ORLANDO, FLORIDA — Asthma is the most common cause of chronic cough in children, but it’s important to be aware of other differential diagnoses for those patients who have less common concerns, according to Rajeev Bhatia, MD, division chief of pulmonology at Phoenix Children’s in Phoenix, Arizona. Bhatia reviewed both the major causes of chronic cough as well as the rare zebras to watch out for in a presentation at the American Academy of Pediatrics (AAP) 2024 National Conference.

“When you see a patient for cough, the most important thing is, history, history, history,” Bhatia said. “There are many, many, many clues in the history, age of onset, and duration.” That includes starting at birth to ensure you don’t miss key details such as a preterm birth. It’s also important to discuss what the cough sounds like, how frequent it is, what makes it better, what makes it worse, and how it’s affecting the child and others around them — all of which can help narrow the diagnosis.

Jose Quijada, DO, a pediatrician with CommuniCare Pediatrics in San Antonio, found the session “incredibly useful” not only because of the specific pointers about each condition but also because of the realistic case studies he included throughout.

“Sometimes when you’re practicing, you focus on what’s most common,” Quijada said, so it was helpful to get a review of some of the key features and red flags that point to less common causes that may need to be considered. He particularly appreciated the discussion of habitual cough and potential treatments because those can be challenging patients and it can be tough to find a middle ground with how much workup to do.
 

Common Causes of Chronic Cough

The coughing from inadequately controlled asthma tends to be nonproductive and worse at night or in the early morning, Bhatia explained, and it’s often accompanied by wheezing, shortness of breath, and chest tightness. While fractional exhaled nitric oxide can be useful, “studies show that it is more useful for to monitor the symptoms rather than to diagnose the asthma,” Bhatia told attendees, but he also added that spirometry can be normal in patients with asthma. In young patients, the Asthma Predictive Index can be an invaluable tool, he also said.

Another common cause of chronic cough is a postinfectious cough, which lasts more than 3 weeks after resolution of acute upper respiratory infection. It occurs in about one in 10 children after a viral infection such as a rhinovirus or respiratory syncytial virus infection and results from extensive inflammation and disruption of the airway epithelial integrity. Chest x-rays are usually normal in these patients, and the cough will usually resolve on its own. Albuterol has not been shown to be any more effective than placebo for a postinfectious cough, and antibiotics similarly have no clinically useful role.

A wet cough that lasts for at least 4 weeks and appears to have no other specific cause may be protracted bacterial bronchitis (PBB). While the cause of PBB isn’t known, it could be due to frequent illnesses that cause airway inflammation and injury over time, thereby making it easier for bacteria to grow and cause infection. Risk factors include tracheomalacia/bronchomalacia and childcare attendance, and typical pathogens include Haemophilus influenzae, Streptococcus pneumonia, and Moraxella catarrhalis.

While an x-ray can be done, radiography is often normal in patients with PBB. Bronchoscopy will reveal purulent secretions. PBB should resolve with at least 2 weeks of antibiotics, including amoxicillin-clavulanate, but the course can be extended to 4 weeks if the cough persists. However, about 40% of patients will have recurrence, and those with recurrent PBB or with a chronic cough unresponsive to 4 weeks of antibiotics should be referred to a pediatric pulmonologist.

Upper airway cough syndrome is the updated name for postnasal drip, which can occur with both allergic and nonallergic rhinitis and chronic rhinosinusitis. This is often a dry, throat-clearing cough that can be accompanied by headaches, nasal congestion, and sinus or facial tenderness. An examination will reveal posterior pharynx cobblestoning, Bhatia said, and empirical use of intranasal steroids can be both diagnostic and therapeutic for upper airway cough syndrome. He also emphasized the importance of taking an environmental history and avoiding exposure of environmental triggers.
 

Uncommon Pulmonary Causes of Chronic Cough

After discussing frequent reasons patients may present with a chronic cough, Bhatia went on to discuss the less common things to consider if the provider has eliminated the other possibilities. These include both pulmonary causes as well as congenital malformations, gastrointestinal causes, and habit cough.

A child who presents with a sudden onset of cough or wheeze in the absence of an upper respiratory infection may have a retained foreign body. This cough can be mistaken for bronchiolitis, asthma, croup, and other infectious conditions, especially because a partial obstruction can make diagnosis confusing or challenging. Adding to the challenge is that most foreign bodies will be radiolucent. A decubitus chest x-ray could be useful, but bronchoscopy is necessary for diagnosis. Bhatia stressed that it’s easy to miss a foreign body in younger children and that the wheezing can be more prominent on one side or another.

Cystic fibrosis, another uncommon cause of chronic cough, is ideally diagnosed via newborn screening, but screening is imperfect and can involve missed diagnoses or false negatives. Over 75% of cystic fibrosis cases are diagnosed by age 2, but that means a substantial number of cases still are not diagnosed until older childhood or later. This cough will be a chronic productive/wet cough.

A family history of cystic fibrosis may be present but doesn’t have to be, so signs to look for include poor weight gain, sinusitis, nasal polyps, clubbing, and isolation of suspicious organisms from a respiratory culture, such as Pseudomonas aeruginosa or Burkholderia cepacia complex. Clubbing in the fingers is a particularly telltale symptom of undiagnosed cystic fibrosis, and bronchiectasis of unknown etiology will be present. Suspicion of cystic fibrosis should lead to a referral to a cystic fibrosis center for a sweat test.

Even rarer than cystic fibrosis is primary ciliary dyskinesia (PCD), an inherited autosomal recessive disease that occurs in about one in 20,000 live births and involves a structural or functional defect in the cilia. About half of all patients with PCD will have situs inversus — an arrangement of chest and abdominal organs that is a mirror image of typical human anatomical presentation — but most people with situs inversus do not have PCD. One type of PCD is Kartagener syndrome, identified by the triad of situs inversus totalis, chronic sinusitis, and bronchiectasis.

Children with PCD present with a chronic productive cough and recurrent pneumonias, and nearly all patients will have rhinosinusitis. About 60% of patients will develop respiratory symptoms such as mild distress or cough in their first month, and recurrent otitis media is common in these patients. PCD diagnosis is based on a combination of genetic testing, nasal nitric oxide, and evaluation of ciliary motion and structure. Clinical suspicion of PCD should lead to a specialist referral.

Nearly all people with PCD will eventually develop bronchiectasis, where the priority should be airway clearance using antibiotics for acute exacerbations and chronic azithromycin therapy for recurrent exacerbations. Patients with chronic rhinosinusitis, chronic otitis media, and nasal polyposis should be referred to an ENT specialist.
 

Other Uncommon Causes of Chronic Cough

A non-pulmonary, uncommon cause of chronic cough is a vascular ring, a congenital anomaly in which blood vessels encircle and potentially constrict the esophagus and/or trachea. The most common type is a double aortic arch, but a right aortic arch or pulmonary artery sling is also possible. These coughs sound harsh and are usually accompanied by stridor, dyspnea and feeding problems. Workup includes an echocardiogram, a CT angiogram, and possibly a bronchoscopy to determine the extent of the airway narrowing. In symptomatic patients, surgery is indicated for correction.

Another congenital malformation that can cause chronic cough is a tracheoesophageal fistula, which occurs in about one in 3500 live births, commonly linked to trisomy disorders and VACTERL. Several types of tracheoesophageal fistula exist, and H-type fistula is associated with late onset symptoms. The cough can be wet or dry and sometimes sounds like barking because of the associated airway collapse. Patients often have recurrent pneumonia, bronchitis, and cough or cyanosis with feeding. Workup should include an upper gastrointestinal series but not with barium, Bhatia said, because that can cause pneumonitis. Instead, the series should be done with a thickened water-soluble contrast material, and a bronchoscopy may be indicated as well.

Though common as a condition in adults, gastroesophageal reflux disease (GERD) is a rare, but possible, cause of chronic cough in children. More often, the reflux is the result of the cough rather than the cause. The most sensitive tool for assessing GERD is esophageal 24-hour pH/impedance reflux monitoring. However, treatment of the reflux for cough is not recommended unless the patient has clinical features of GERD, including dystonic neck posturing in infants, heartburn, regurgitation, or other symptoms. If the patient has clinical symptoms, then treatment is acid suppressive therapy for 4-8 weeks, followed by a clinical reassessment.

An uncommon cause of chronic cough with no biological mechanism is habit cough. Habit cough is most easily distinguished from other coughs by its sounds, a “large, loud, honking noise,” Bhatia said. It also lacks a clear trigger and is usually absent during sleep, but it can be continuous during the day. Frustratingly, the patients themselves often don’t seem bothered by the cough, but “it’s very disruptive in the school and everywhere else,” Bhatia said. Families and/providers will often have tried multiple treatments and seen no improvement with habit cough.

The first thing to do with habit cough is reassure the family that there’s nothing serious going on because they are often worried by this point. Several non-pharmaceutical treatments can be effective, such as suggestion therapy or the “warm water technique,” in which the patient takes a sip of warm water every time they feel the urge to cough. “If they’re able to break the cycle, most of the time, they are fine,” Bhatia said. In rarer cases, more involved behavioral interventions may be indicated, such as a psychology referral if an underlying anxiety or other behavioral disorder is contributing.
 

Newer Causes of Cough

Two more recent causes of cough to watch for are long COVID and e-cigarette or vaping product–associated lung injury (EVALI), Bhatia said. The clearest sign of EVALI is a history of e-cigarette/vaping exposure, but clinical symptoms include a dry cough that occurs with dyspnea and chest pain. A chest x-ray may show diffuse, hazy, or consolidative opacities. Sometimes antibiotics or steroids can be helpful, but the evidence isn’t strong, and the most effective treatment is stopping e-cigarette use. Less commonly, passive exposure to vaping can also be associated with EVALI.

The most recent research on long COVID suggests that about 10-20% of children with acute COVID develop long COVID, and about a quarter of these patients develop a chronic dry cough. It’s often associated with fatigue and shortness of breath, which can be assessed with cardiopulmonary exercise testing. Sometimes a short trial of inhaled steroids can help.

Bhatia also mentioned a handful of other uncommon causes of chronic cough that most American pediatricians are unlikely to see: Childhood interstitial lung disease, tuberculosis, use of Angiotensin-Converting Enzyme inhibitors, and a build-up of ear wax via the Arnold’s nerve reflex.
 

Evaluation and Workup

Bhatia also discussed what to cover while taking a history and questions to ask. The history should include the type of cough, the onset timing (sudden vs gradual), associated symptoms, the cough trajectory, medications the patient is taking, and the patient’s past medical history and environmental exposures. Those attributes are included in this more comprehensive list of questions to consider during evaluation, adapted from a list provided in a 2019 article in Paediatric Respiratory Reviews:

• Age of onset and duration?
• Was the onset sudden or associate with an illness?
• Is the cough wet or dry?
• What does the cough sound like?
• How often does the cough occur?
• Is it progressive?
• Is it present during sleep?
• Are there any other associated symptoms, such as wheeze, dyspnea, vomiting, chest pain, etc?
• Are there any exacerbating factors or known triggers?
• Are there any relieving factors, including a trial of bronchodilators?
• Has there been exposure to auto-irritants, such as secondhand smoke?
• What is the cough’s effect on the child and on others around the child?
• Does the child have any other underlying conditions such as neuromuscular disease or asthma?
• What medications is the child taking or has recently taken?
• Is there a family history of atopy and/or respiratory disease?

Bhatia also recommended paying special attention to the following red flags or key features that may help more quickly narrow the diagnosis and often require a specialist referral:

• Digital clubbing, failure to thrive, or low tone
• An abnormal cardiac exam
• Tachypnea, hypoxemia, chest retractions, or hemoptysis
• Abnormal breath sounds such as unilateral wheezing or coarse crackles
• Abnormal spirometry in those aged 5 and older showing reversible obstruction, which often indicates asthma
• An abnormal chest x-ray with, for example, bilateral infiltrates, hyperinflation, right middle lobe syndrome, situs inversus, unilateral hyperlucency, a right aortic arch, etc.

No external funding was used for the presentation. Bhatia and Quijada had no disclosures.

The cough can be wet or dry and sometimes sounds like barking because of the associated airway collapse. Patients often have recurrent pneumonia, bronchitis, and cough or cyanosis with feeding. Workup should include an upper gastrointestinal series but not with barium, Bhatia said, because that can cause pneumonitis. Instead, the series should be done with a thickened water-soluble contrast material, and a bronchoscopy may be indicated as well.

Though common as a condition in adults, gastroesophageal reflux disease (GERD) is a rare, but possible, cause of chronic cough in children. More often, the reflux is the result of the cough rather than the cause. The most sensitive tool for assessing GERD is esophageal 24-hour pH/impedance reflux monitoring. However, treatment of the reflux for cough is not recommended unless the patient has clinical features of GERD, including dystonic neck posturing in infants, heartburn, regurgitation, or other symptoms. If the patient has clinical symptoms, then treatment is acid suppressive therapy for 4-8 weeks, followed by a clinical reassessment.

An uncommon cause of chronic cough with no biological mechanism is habit cough. Habit cough is most easily distinguished from other coughs by its sounds, a “large, loud, honking noise,” Bhatia said. It also lacks a clear trigger and is usually absent during sleep, but it can be continuous during the day. Frustratingly, the patients themselves often don’t seem bothered by the cough, but “it’s very disruptive in the school and everywhere else,” Bhatia said. Families and/providers will often have tried multiple treatments and seen no improvement with habit cough.

The first thing to do with habit cough is reassure the family that there’s nothing serious going on because they are often worried by this point. Several non-pharmaceutical treatments can be effective, such as suggestion therapy or the “warm water technique,” in which the patient takes a sip of warm water every time they feel the urge to cough. “If they’re able to break the cycle, most of the time, they are fine,” Bhatia said. In rarer cases, more involved behavioral interventions may be indicated, such as a psychology referral if an underlying anxiety or other behavioral disorder is contributing.
 

Newer Causes of Cough

Two more recent causes of cough to watch for are long COVID and e-cigarette or vaping product–associated lung injury (EVALI), Bhatia said. The clearest sign of EVALI is a history of e-cigarette/vaping exposure, but clinical symptoms include a dry cough that occurs with dyspnea and chest pain. A chest x-ray may show diffuse, hazy, or consolidative opacities. Sometimes antibiotics or steroids can be helpful, but the evidence isn’t strong, and the most effective treatment is stopping e-cigarette use. Less commonly, passive exposure to vaping can also be associated with EVALI.

The most recent research on long COVID suggests that about 10-20% of children with acute COVID develop long COVID, and about a quarter of these patients develop a chronic dry cough. It’s often associated with fatigue and shortness of breath, which can be assessed with cardiopulmonary exercise testing. Sometimes a short trial of inhaled steroids can help.

Bhatia also mentioned a handful of other uncommon causes of chronic cough that most American pediatricians are unlikely to see: Childhood interstitial lung disease, tuberculosis, use of Angiotensin-Converting Enzyme inhibitors, and a build-up of ear wax via the Arnold’s nerve reflex.
 

Evaluation and Workup

Bhatia also discussed what to cover while taking a history and questions to ask. The history should include the type of cough, the onset timing (sudden vs gradual), associated symptoms, the cough trajectory, medications the patient is taking, and the patient’s past medical history and environmental exposures. Those attributes are included in this more comprehensive list of questions to consider during evaluation, adapted from a list provided in a 2019 article in Paediatric Respiratory Reviews:

• Age of onset and duration?
• Was the onset sudden or associate with an illness?
• Is the cough wet or dry?
• What does the cough sound like?
• How often does the cough occur?
• Is it progressive?
• Is it present during sleep?
• Are there any other associated symptoms, such as wheeze, dyspnea, vomiting, chest pain, etc?
• Are there any exacerbating factors or known triggers?
• Are there any relieving factors, including a trial of bronchodilators?
• Has there been exposure to auto-irritants, such as secondhand smoke?
• What is the cough’s effect on the child and on others around the child?
• Does the child have any other underlying conditions such as neuromuscular disease or asthma?
• What medications is the child taking or has recently taken?
• Is there a family history of atopy and/or respiratory disease?

Bhatia also recommended paying special attention to the following red flags or key features that may help more quickly narrow the diagnosis and often require a specialist referral:

• Digital clubbing, failure to thrive, or low tone
• An abnormal cardiac exam
• Tachypnea, hypoxemia, chest retractions, or hemoptysis
• Abnormal breath sounds such as unilateral wheezing or coarse crackles
• Abnormal spirometry in those aged 5 and older showing reversible obstruction, which often indicates asthma
• An abnormal chest x-ray with, for example, bilateral infiltrates, hyperinflation, right middle lobe syndrome, situs inversus, unilateral hyperlucency, a right aortic arch, etc.

No external funding was used for the presentation. Bhatia and Quijada had no disclosures.

Noninvasive surveillance with multitarget stool DNA testing or fecal immunochemical testing (FIT) could potentially match colonoscopy for reducing long-term colorectal cancer (CRC) incidence and mortality. It might also reduce colonoscopies by an estimated 15%-41%.

The greatest reduction would likely be achieved by annual FIT-based surveillance, especially with FIT FOB-Gold at a threshold of at least 32 µg/g feces, according to findings from the Dutch MOCCAS study published in Gastroenterology.

In this cross-sectional observational study, the multitarget DNA test outperformed FIT for detecting advanced precursor lesions, especially serrated polyps. According to long-term-impact mathematical modeling, however, DNA-based surveillance would be more costly than colonoscopy surveillance, whereas FIT would save costs.

“With the worldwide implementation of FIT-based screening programs, following a positive test, many more people enter surveillance programs after polypectomy. This results in an increased pressure on the colonoscopy capacity and healthcare budgets,” lead author Beatriz Carvalho, PhD, a molecular biologist in the Department of Pathology of the Netherlands Cancer Institute in Amsterdam, said in an interview.

Study Details

The cross-sectional observational study included individuals aged 50-75 years who provided stool samples for the DNA test and two FITs. Test accuracy was calculated for all surveillance indications.

For the post-polypectomy indication only, which is the most common and associated with a relatively low CRC risk, the long-term impact of stool-based surveillance was evaluated with the Adenoma and Serrated Pathway to Colorectal Cancer model. Stool-based strategies were simulated to tune each test’s positivity threshold to obtain strategies that are at least as effective as colonoscopy surveillance.

A total of 3453 individuals had results for all stool tests and colonoscopy; among them, 2226 had previously undergone polypectomy, 1003 had a history of CRC, and 224 had a familial risk.

Areas under the receiver operating characteristic curve for advanced neoplasia were as follows:

• 0.72 (95% CI, 0.69-0.75) for the multitarget stool DNA test
• 0.61 (95% CI, 0.58-0.64) for the FIT OC-SENSOR 
• 0.59 (95% CI, 0.56-0.61) for the FIT FOB-Gold 

Stool-based surveillance was estimated to be at least as effective as colonoscopy surveillance and required 5.6 to 9.5 stool tests over a person’s lifetime. DNA-based surveillance was more costly than colonoscopy surveillance, whereas FIT-based surveillance saved costs.

“These findings provide a basis to embark on a prospective intervention study to assess the clinical utility of FIT as an alternative to colonoscopy surveillance in a post-polypectomy CRC surveillance population,” the authors wrote.

In the United States, Ladabaum said, it would likely be possible to find FIT-based strategies that closely approximate or match surveillance colonoscopy — “if we could deploy FIT with the required flexibility, for example, by adjusting the threshold and if the reference surveillance standard were somewhat relaxed compared with current guidelines.”

He worries, however, that if FIT for screening and FIT for surveillance were optimized at different hemoglobin detection thresholds, “there could be confusion and room for error in real-world clinical implementation.”

The authors called for research to increase understanding of the mechanisms underlying progression from adenomas to malignancy over time, which may yield better biomarkers to improve stool test accuracy.

This study was funded by the Alpe d’HuZes charity and the Dutch Cancer Society. Exact Sciences provided test equipment and performed multitarget stool DNA test analysis. Sentinel Diagnostics provided equipment and reagents.

Carvalho and Veerle M. H. Coupé, PhD, disclosed several patents pending and/or issued. Other coauthors disclosed multiple financial relationships with private companies, including Exact Sciences and Sentinel, for research support, travel, board membership, advisory or speaker fees, consulting, employment, stock ownership, or patents.

Ladabaum disclosed no competing interests relevant to his comments.

A new serum containing 2-mercaptonicotinoyl glycine (Melasyl) as its main ingredient was at least as good as, if not better than, cysteamine 5% cream in treating facial melasma in a randomized controlled study presented at the European Academy of Dermatology and Venereology (EADV) 2024 Congress.

“Melasyl is a new potent melanogenesis inhibitor that exhibits a unique mode of action while preserving melanocyte integrity,” Mukta Sachdev, MD, head of the Department of Dermatology at Manipal Hospital in Bangalore, India, said at a late-breaking news session.

Both the serum and the cysteamine cream lightened participants’ skin to a similar extent, according to the modified Melasma Area and Severity Index (mMASI), with respective reductions of 4.19 and 3.81 points over a period of 4 months from baseline values of 11.15 and 10.93.

The mMASI score ranges from 0 to 24, with the lowest score representing the least and the highest score the most severe hyperpigmentation of the skin.

But the serum performed better than the cream by another measure. Judged by investigators blinded to which preparation study participants had been using, there was a significantly higher reduction in the Investigator Global Assessment (IGA) score from baseline among those treated with the serum than among those treated with the cream (−51.85% vs −39.06%; P = .0163). 

Moreover, after 4 months of treatment, there were significantly more participants with clear or almost clear skin with the serum than with the cream (17.46% vs 7.81%; P = .0163), Sachdev reported.

Other skin parameters relative to melasma, such as the brightness of skin tone and evenness of the improvement, improved more in the participants using the serum vs cream, she said. 

With “no side effects, no local skin reactions,” Sachdev said, “quality of life improved significantly and similarly, and almost all subjects in both groups were very satisfied with their treatment options.”
 

Active Ingredients

Margarida Gonçalo, MD, PhD, professor of dermatology at the University of Coimbra, in Portugal, who co-chaired the late-breaking news session, commented: “It’s really nice to have new products to treat such a devastating disease.”

Session co-chair, Lidia Rudnicka, MD, head of the Department of Dermatology, Medical University of Warsaw, in Poland, and president of the Polish Dermatological Society, wanted to know more about the active ingredients of the serum and the study’s design. 

Sachdev replied that the serum also contains other ingredients that provide “antioxidant protection” and moisturization. These include retinyl palmitate, which works on the dermal-epidermal junction, and hyaluronic acid, as well as “soothing agents,” such as the medicinal herb Centella asiatica, she said.
 

Study Design

Conducted at a single center in India, the study involved 127 adults aged 20-50 years with melasma. For inclusion, the participants had to have facial epidermal or mixed melasma (phototypes III-V) for more than 1 year; those with dermal melasma were excluded. 

Participants were randomly allocated to receive either the serum, which was applied topically to the areas of interest twice a day in the morning and then at bedtime (n = 63), or cysteamine cream (n = 64), which was applied once a day in addition to a neutral moisturizer. Treatment was for 4 months, with an on-site visit every month. 

All participants were supplied with the same sunscreen/ultraviolet protector applied twice a day (once in the morning and again at midday) and a neutral hydrating cleanser that was used in the morning and evening. 
 

Practical Implications

Over 4 months, both products showed significant improvement in melasma without reaching a plateau, Sachdev reported, with the serum demonstrating superior efficacy and tolerability, as judged by the investigators. 

The study suggests that the serum is a promising non-hydroquinone treatment for melasma, she said. Hydroquinone-containing topical preparations are used to depigment the skin, but their long-term use can be limited for safety reasons. 

“When products like this demonstrate improvement, it is something for the dermatologist to think about because we now have newer ingredients, which are safer and well tolerated,” she continued, noting that there appeared to be no risk for exogenous ochronosis, which can occur with long-term application of hydroquinone.

“So, I think the armamentarium of non-hydroquinone products for the treatment of melasma is rapidly expanding, and there are studies now with clinically proven efficacy,” Sachdev concluded. 

The study was supported by L’Oréal France La Roche-Posay, which launched Melasyl in March 2024. Sachdev reported receipt of research support and honoraria from the company. Gonçalo and Rudnicka were not involved in the study and had no relevant conflicts of interest to report.

TOPLINE:

The Fracture Risk Assessment Tool (FRAX), with bone mineral density, predicts the risk for major osteoporotic fractures and hip fractures in patients with cancer, but FRAX without bone mineral density slightly overestimates these risks, a new analysis found.

METHODOLOGY:

• Cancer-specific guidelines recommend using FRAX to assess fracture risk, but its applicability in patients with cancer remains unclear.
• This retrospective cohort study included 9877 patients with cancer (mean age, 67.1 years) and 45,875 matched control individuals without cancer (mean age, 66.2 years). All participants had dual-energy x-ray absorptiometry (DXA) scans.
• Researchers collected data on bone mineral density and fractures. The 10-year probabilities of major osteoporotic fractures and hip fractures were calculated using FRAX, and the observed 10-year probabilities of these fractures were compared with FRAX-derived probabilities.
• Compared with individuals without cancer, patients with cancer had a shorter mean follow-up duration (8.5 vs 7.6 years), a slightly higher mean body mass index, and a higher percentage of parental hip fractures (7.0% vs 8.2%); additionally, patients with cancer were more likely to have secondary causes of osteoporosis (10% vs 38.4%) and less likely to receive osteoporosis medication (9.9% vs 4.2%).

TAKEAWAY:

• Compared with individuals without cancer, patients with cancer had a significantly higher incidence rate of major fractures (12.9 vs 14.5 per 1000 person-years) and hip fractures (3.5 vs 4.2 per 1000 person-years).
• FRAX with bone mineral density exhibited excellent calibration for predicting major osteoporotic fractures (slope, 1.03) and hip fractures (0.97) in patients with cancer, regardless of the site of cancer diagnosis. FRAX without bone mineral density, however, underestimated the risk for both major (0.87) and hip fractures (0.72).
• In patients with cancer, FRAX with bone mineral density findings were associated with incident major osteoporotic fractures (hazard ratio [HR] per SD, 1.84) and hip fractures (HR per SD, 3.61).
• When models were adjusted for FRAX with bone mineral density, patients with cancer had an increased risk for both major osteoporotic fractures (HR, 1.17) and hip fractures (HR, 1.30). No difference was found in the risk for fracture between patients with and individuals without cancer when the models were adjusted for FRAX without bone mineral density, even when considering osteoporosis medication use.

IN PRACTICE:

“This retrospective cohort study demonstrates that individuals with cancer are at higher risk of fracture than individuals without cancer and that FRAX, particularly with BMD [bone mineral density], may accurately predict fracture risk in this population. These results, along with the known mortality risk of osteoporotic fractures among cancer survivors, further emphasize the clinical importance of closing the current osteoporosis care gap among cancer survivors,” the authors wrote.

LIMITATIONS:

This study cohort included a selected group of cancer survivors who were referred for DXA scans and may not represent the general cancer population. The cohort consisted predominantly of women, limiting the generalizability to men with cancer. Given the heterogeneity of the population, the findings may not be applicable to all cancer subgroups. Information on cancer stage or the presence of bone metastases at the time of fracture risk assessment was lacking, which could have affected the findings.

TOPLINE:

The Fracture Risk Assessment Tool (FRAX), with bone mineral density, predicts the risk for major osteoporotic fractures and hip fractures in patients with cancer, but FRAX without bone mineral density slightly overestimates these risks, a new analysis found.

METHODOLOGY:

• Cancer-specific guidelines recommend using FRAX to assess fracture risk, but its applicability in patients with cancer remains unclear.
• This retrospective cohort study included 9877 patients with cancer (mean age, 67.1 years) and 45,875 matched control individuals without cancer (mean age, 66.2 years). All participants had dual-energy x-ray absorptiometry (DXA) scans.
• Researchers collected data on bone mineral density and fractures. The 10-year probabilities of major osteoporotic fractures and hip fractures were calculated using FRAX, and the observed 10-year probabilities of these fractures were compared with FRAX-derived probabilities.
• Compared with individuals without cancer, patients with cancer had a shorter mean follow-up duration (8.5 vs 7.6 years), a slightly higher mean body mass index, and a higher percentage of parental hip fractures (7.0% vs 8.2%); additionally, patients with cancer were more likely to have secondary causes of osteoporosis (10% vs 38.4%) and less likely to receive osteoporosis medication (9.9% vs 4.2%).

TAKEAWAY:

• Compared with individuals without cancer, patients with cancer had a significantly higher incidence rate of major fractures (12.9 vs 14.5 per 1000 person-years) and hip fractures (3.5 vs 4.2 per 1000 person-years).
• FRAX with bone mineral density exhibited excellent calibration for predicting major osteoporotic fractures (slope, 1.03) and hip fractures (0.97) in patients with cancer, regardless of the site of cancer diagnosis. FRAX without bone mineral density, however, underestimated the risk for both major (0.87) and hip fractures (0.72).
• In patients with cancer, FRAX with bone mineral density findings were associated with incident major osteoporotic fractures (hazard ratio [HR] per SD, 1.84) and hip fractures (HR per SD, 3.61).
• When models were adjusted for FRAX with bone mineral density, patients with cancer had an increased risk for both major osteoporotic fractures (HR, 1.17) and hip fractures (HR, 1.30).

Twice a month, a 40-foot-long truck transformed into a mobile clinic travels the Rio Grande Valley to provide rural Texans with women’s health care, including birth control.

The clinic, called the UniMóvil, is part of the Healthy Mujeres program at the University of Texas Rio Grande Valley School of Medicine in Edinburg.

The United States has about 3000 mobile health programs. But Saul Rivas, an ob.gyn., said he wasn’t aware of any that shared the specific mission of Healthy Mujeres when he helped launch the initiative in 2017. “Mujeres” means “women” in Spanish.

It’s now part of a small but growing number of mobile programs aimed at increasing rural access to women’s health services, including long-acting reversible contraception.

There are two kinds of these highly effective methods: intrauterine devices, known as IUDs, and hormonal implants inserted into the upper arm. These birth control options can be especially difficult to obtain — or have removed — in rural areas.

“Women who want to prevent an unintended pregnancy should have whatever works best for them,” said Kelly Conroy, senior director of mobile and maternal health programs at the University of Arkansas for Medical Sciences, Little Rock.

The school is launching a mobile women’s health and contraception program in rural parts of the state in October.

Rural areas have disproportionately fewer doctors, including ob.gyns., than urban areas. And rural providers may not be able to afford to stock long-acting birth control devices or may not be trained in administering them, program leaders say.

Mobile clinics help shrink that gap in rural care, but they can be challenging to operate, said Elizabeth Jones, a senior director at the National Family Planning & Reproductive Health Association.

Money is the greatest obstacle, Jones said. The Texas program costs up to $400,000 a year. A 2020 study of 173 mobile clinics found they cost an average of more than $630,000 a year. Mobile dental programs were the most expensive, averaging more than $1 million.

While many programs launch with the help of grants, they can be difficult to sustain, especially with over a decade of decreased or stagnant funding to Title X, a federal money stream that helps low-income people receive family planning services.

For example, a mobile contraception program serving rural Pennsylvania lasted less than 3 years before closing in 2023. It shut down after losing federal funding, said a spokesperson for the clinic that ran it.

Rural mobile programs aren’t as efficient or profitable as brick-and-mortar clinics. That’s because staff members may have to make hours-long trips to reach towns where they’ll probably see fewer patients than they would at a traditional site, Jones said.

She said organizations that can’t afford mobile programs can consider setting up “pop-up clinics” at existing health and community sites in rural areas.

Maria Briones is a patient who has benefited from the Healthy Mujeres program in southern Texas. The 41-year-old day care worker was concerned because she wasn’t getting her menstrual period with her IUD.

She considered going to Mexico to have the device removed because few doctors take her insurance on the US side of the Rio Grande Valley.

But Briones learned that the UniMóvil was visiting a small Texas city about 20 minutes from her home. She told the staff there that she doesn’t want more kids but was worried about the IUD.

Briones decided to keep the device after learning it’s safe and normal not to have periods while using an IUD. She won’t get billed for her appointment with the mobile clinic, even though the university health system doesn’t take her insurance.

“They have a lot of patience, and they answered all the questions that I had,” Briones said.

IUDs and hormonal implants are highly effective and can last up to 10 years. But they’re also expensive — devices can cost more than $1,000 without insurance — and inserting an IUD can be painful.

Patient-rights advocates are also concerned that some providers pressure people to use these devices.

They say ethical birth control programs aim to empower patients to choose the contraceptive method — if any — that is best for them, instead of promoting long-acting methods in an attempt to lower birth and poverty rates. They point to the history of eugenics-inspired sterilization and even more recent incidents.

For example, an investigation by Time magazine found doctors are more likely to push Black, Latina, young, and low-income women than other patients to use long-acting birth control — and to refuse to remove the devices.

Rivas said Healthy Mujeres staffers are trained on this issue.

“Our goal isn’t necessarily to place IUDs and implants,” he said. It’s to “provide education and help patients make the best decisions for themselves.”

David Wise, a spokesperson for the University of Arkansas for Medical Sciences, said staff members with the university’s mobile program will ask patients if they want to get pregnant in the next year, and will support their choice. The Arkansas and Texas programs also remove IUDs and hormonal arm implants if patients aren’t happy with them.

The Arkansas initiative will visit 14 rural counties with four vehicles the size of food trucks that were used in previous mobile health efforts. Staffing and equipment will be covered by a 2-year, $431,000 grant from an anonymous donor, Wise said.

In addition to contraception, faculty and medical residents staffing the vehicles will offer women’s health screenings, vaccinations, prenatal care, and testing and treatment for sexually transmitted infections.

Rivas said the Texas program was inspired by a study that found that, 6 months after giving birth, 34% of surveyed Texas mothers said long-acting contraception is their preferred birth control option — but only 13% were using that method.

“We started thinking about ways to address that gap,” Rivas said.

Healthy Mujeres, which is funded through multiple grants, started with a focus on contraception. It later expanded to services such as pregnancy ultrasounds, cervical cancer screenings, and testing for sexually transmitted infections.

While the Texas and Arkansas programs can bill insurance, they also have funding to help uninsured and underinsured patients afford their services. Both use community health workers — called promotoras in largely Spanish-speaking communities like the Rio Grande Valley — to connect patients with food, transportation, additional medical services, and other needs.

They partner with organizations that locals trust, such as food pantries and community colleges, which let the mobile units set up in their parking lots. And to further increase the availability of long-acting contraception in rural areas, the universities are training their students and local providers on how to insert, remove, and get reimbursed for the devices.

One difference between the programs is dictated by state laws. The Arkansas program can provide birth control to minors without a parent or guardian’s consent. But in Texas, most minors need consent before receiving health care, including contraception.

Advocates say these initiatives might help lower the rates of unintended and teen pregnancies in both states, which are higher than the national average.

Rivas and Conroy said their programs haven’t received much pushback. But Rivas said some churches that had asked the UniMóvil to visit their congregations changed their minds after learning the services included birth control.

Catherine Phillips, director of the Respect Life Office at Arkansas’ Catholic diocese, said the diocese supports efforts to achieve health care equity and she’s personally interested in mobile programs that visit rural areas such as where she lives.

But Phillips said the Arkansas program’s focus on birth control, especially long-acting methods, violates the teachings of the Catholic Church. Offering these services to minors without parental consent “makes it more egregious,” she said.

Jones said that, while these programs have hefty costs and other challenges, they also have benefits that can’t be measured in numbers.

“Building community trust and making an impact in the communities most impacted by health inequities — that’s invaluable,” she said.

TOPLINE:

BARCELONA, SPAIN — Patients who receive a diagnosis of neovascular age-related macular degeneration (nAMD) from their primary care clinician may be less likely to adhere to treatment than those who receive the diagnosis from a specialist who provides anti–vascular endothelial growth factor (anti-VEGF) therapy, according to global survey results presented at the European Society of Retina Specialists (EURETINA) 2024. Likewise, patients who self-pay for the medication or who have bilateral nAMD may be less adherent to therapy, researchers found.

METHODOLOGY:

• Researchers analyzed data from 4558 patients with nAMD who participated in the Barometer Global Survey, which involved 77 clinics in 24 countries, including Canada, Mexico, Brazil, Germany, and France.
• The survey included multiple-choice questions on personal characteristics, disease awareness, experiences with treatment, and logistical challenges with getting to appointments.
• An exploratory statistical analysis identified 19 variables that influenced patient adherence to anti-VEGF therapy.
• The researchers classified 670 patients who missed two or more appointments during a 12-month period as nonadherent.

TAKEAWAY:

• Patients with nAMD diagnosed by their family doctor or general practitioner had a threefold higher risk for nonadherence than those diagnosed by the physician treating their nAMD.
• Self-pay was associated with more than twice the odds of nonadherence compared with having insurance coverage (odds ratio [OR], 2.5).
• Compared with unilateral nAMD, bilateral nAMD was associated with higher odds of multiple missed appointments (OR, 1.7).
• Nonadherence increased with the number of anti-VEGF injections, which may show that “longer treatment durations could permit more opportunities for absenteeism,” the investigators noted.

IN PRACTICE:

“Identifying patient characteristics and challenges that may be associated with nonadherence allows clinicians to recognize patients at risk for nonadherence and provide further support before these patients begin to miss appointments,” the study authors wrote.

TOPLINE:

BARCELONA, SPAIN — Patients who receive a diagnosis of neovascular age-related macular degeneration (nAMD) from their primary care clinician may be less likely to adhere to treatment than those who receive the diagnosis from a specialist who provides anti–vascular endothelial growth factor (anti-VEGF) therapy, according to global survey results presented at the European Society of Retina Specialists (EURETINA) 2024. Likewise, patients who self-pay for the medication or who have bilateral nAMD may be less adherent to therapy, researchers found.

METHODOLOGY:

• Researchers analyzed data from 4558 patients with nAMD who participated in the Barometer Global Survey, which involved 77 clinics in 24 countries, including Canada, Mexico, Brazil, Germany, and France.
• The survey included multiple-choice questions on personal characteristics, disease awareness, experiences with treatment, and logistical challenges with getting to appointments.
• An exploratory statistical analysis identified 19 variables that influenced patient adherence to anti-VEGF therapy.
• The researchers classified 670 patients who missed two or more appointments during a 12-month period as nonadherent.

TAKEAWAY:

• Patients with nAMD diagnosed by their family doctor or general practitioner had a threefold higher risk for nonadherence than those diagnosed by the physician treating their nAMD.
• Self-pay was associated with more than twice the odds of nonadherence compared with having insurance coverage (odds ratio [OR], 2.5).
• Compared with unilateral nAMD, bilateral nAMD was associated with higher odds of multiple missed appointments (OR, 1.7).
• Nonadherence increased with the number of anti-VEGF injections, which may show that “longer treatment durations could permit more opportunities for absenteeism,” the investigators noted.

Premenstrual disorders (PMDs), including premenstrual dysphoric disorder (PMDD), adversely affect the lives of millions of women worldwide. Most girls and women — as many as 80%-90%— will experience some premenstrual discomfort such as irritability, depressed mood, food or alcohol cravings, bloating, body aches, breast pain, constipation, or fatigue.

Diagnosable menstrual disorders include, collectively, premenstrual syndrome (PMS); PMDD, formerly called late luteal phase dysphoric disorder; and premenstrual worsening of another medical condition.

The most debilitating of these is PMDD, which has an estimated prevalence of about 4%-8% in women of reproductive age, according to obstetrician/gynecologist Hoosna Haque, MD, assistant professor of medicine at Columbia University Irving Medical Center in New York City.

“It’s difficult to be sure because this condition is underreported,” said Luu D. Ireland, MD, MPH, assistant professor of obstetrics and gynecology at UMass Memorial Medical Center in Worcester, Massachusetts. “But more women are coming forward, and there’s more discussion and media coverage of this condition.”

Occurring in the same post-follicular timeframe as PMS, PMDD takes cyclical discomfort to a more intense level, with a trifecta of affective comorbidities, somatic manifestations, and behavioral changes, all of which can seriously impair daily functioning, including work, physical activities, and personal relationships. Romantic and marital relationships can be particularly impaired.

Although recent cost figures are lacking, PMDs exact a considerable economic toll with increased direct healthcare costs from doctor visits and pharmaceuticals. A 2010 study found that US women with PMS were more likely to accrue in excess of $500 in healthcare visit costs over 2 years, and the figure would likely be higher today. PMDs also increase work/school absenteeism and reduce productivity.
 

Etiology

Brain areas that regulate emotion and behavior contain receptors for estrogen, progesterone, and other sex hormones, which affect the functioning of neurotransmitter systems influencing mood and thinking. Although the precise pathophysiology remains unclear, PMDD is likely multifactorial and results in a heightened sensitivity to normal fluctuations in estrogen and progesterone during the luteal phase of the menstrual cycle and dysfunction of the serotonin and gamma-aminobutyric acid neurotransmitter systems.

Patients with PMDD have lower levels of cortisol and beta-endorphins during both the follicular and luteal phases, suggesting abnormalities in the hypothalamic-pituitary-gonadal axis (HPGA), which is consistent with dysregulation in mood disorders.
 

Risk Factors

These include family history, past traumatic events, smoking, chronic pain syndrome, and obesity. There may be a genetic component as recent studies have suggested the involvement of the gene that codes for the serotonergic 5HT1A receptor and allelic variants of ESR1 in the development of PMS/PMDD.

A particularly concerning aspect of PMDs of any sort is their possible association with a higher risk for death from non-natural causes. In a recent Swedish study, which did not distinguish between PMDs in general and PMDD in particular, patients had an almost 60% greater risk for death from non-natural causes and nearly twice the risk for death by suicide compared with women without PMDs.

Those diagnosed with a PMD at an early age showed excess mortality, and the risk for suicide was elevated regardless of age. “These findings support the need for careful follow-up for young women with PMDs and the need for suicide prevention strategies,” wrote lead author Marion Opatowski, PhD, a medical epidemiologist at Karolinska Institutet in Stockholm, Sweden. “Women with severe PMDD should definitely be monitored for suicidal thoughts or behavior and they should have an emergency outreach plan in place,” Haque added.
 

Diagnosis

Although the somatic manifestations of PMDD resemble those of PMS, they are more severe and associated psychological symptoms are greater. “In my experience, PMDD symptoms can last the whole 2 weeks of the luteal phase, whereas PMS might occur a couple of days before menstruation,” said Ireland.

Symptoms include labile mood, nervousness, hopelessness, anger and aggressiveness, as well as tension and irritability. Those affected may have suicidal thoughts or even behaviors. In addition to a lethargic loss of interest in normal activities, patients with PMDD may feel paranoid, confused, exhausted, or out of control and experience insomnia or hypersomnia. They may have trouble concentrating or remembering. Some patients with PMDD may already be prone to attention-deficit/hyperactivity disorder and non–cycle-related depression, anxiety, and panic attacks.

Diagnosis is based on the presence of any five of the typical affective, somatic, or behavioral symptoms outlined above in the week before onset of menses.

“It’s important to do a careful diagnosis for PMDD and rule out other underlying conditions such as existing depressive or anxiety disorders,” said Haque. “Symptoms tend to be more intense in periods of high hormonal fluctuation such as in the postpartum and perimenopause periods. Women with PMDD should be monitored for postpartum depression.”

PMDD is considered both a gynecologic-genitourinary disorder and an affective condition.

In 2013, it was controversially included as a depressive disorder in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. Strongly advocated by some patients, psychiatrists, and pharmaceutical companies, its inclusion was criticized by psychologists and generalists, who feared it would lead to overdiagnosis and pathologization of normal female hormonal changes. Women’s advocates protested that this inclusion would stigmatize female biology and harm their advance in society and the workplace, while some doctors continued to dismiss PMDD as not a serious concern.
 

Treatments

In its latest clinical practice guideline on PMDs, the American College of Obstetricians and Gynecologists (ACOG), for which Ireland served as the lead author, recommends that most patients with PMDD get medical treatment and outlines the following therapies, based on varying degrees of evidence strength.

Antidepressants. These may benefit patients with strong affective symptoms. Selective serotonin reuptake inhibitors such as sertraline (Zoloft), citalopram (Celexa), escitalopram (Lexapro), or fluoxetine (Prozac) are first choices.

Antidepressants may interrupt aberrant signaling in the HPGA, the circuit linking brain and ovaries and regulating the reproductive cycle. Serotonin norepinephrine reuptake inhibitor venlafaxine (Effexor) may also improve symptoms, but other types of antidepressants have not proven effective.

“The response to these well-tolerated drugs is rapid and can happen in the first 2 days,” said Ireland. The drugs may be taken either just in the luteal period or over the month, especially by patients with chronic depression or anxiety.

Hormonal therapy. ACOG recommends the use of combined oral contraceptives (COCs), gonadotropin-releasing hormone (GnRH) agonists to induce anovulation (with combined add-back hormones), progestin-only methods, and noncontraceptive continuous estrogen formulations. It notes, however, that COCs have not been more effective than placebo in reducing depressive symptom scores.

If symptoms do not improve over two to three cycles, an alternate therapy should be considered. Haque recommends an assessment after three cycles and then yearly.

Some women in her practice take both antidepressant and hormone therapy. “Unfortunately, there are no new pharmaceutical treatments on the horizon, but we have good ones already and we would love for patients to utilize them more often,” Ireland said.

Nonsteroidal anti-inflammatory drugs. Limited evidence shows these may reduce physical symptoms such as abdominal cramps, headaches, and general body aches, as well as some mood-related symptoms, which may be an indirect effect of pain alleviation.

Surgery. For women with the most severe intractable symptoms, bilateral oophorectomy with or without hysterectomy may be a last-resort option when medical management has failed. A trial period of GnRH agonist therapy (with or without adjunctive estrogen add-back treatment) is advised before surgery to predict a patient’s response to surgical management.

Acupuncture. ACOG suggests that acupuncture may help manage physical and affective premenstrual symptoms.

Diet. The usual dietary advice for premenstrual symptoms — such as consuming less caffeine, sugar, or alcohol and eating smaller, more frequent meals — is unlikely to help women with PMDD.

Exercise. Although it has not been well studied for PMDD, aerobic exercises such as walking, swimming, and biking tend to improve mood and energy levels in general. Exercise may reduce symptoms through several pathways, including effects on beta-endorphin, cortisol, and ovarian hormone levels.

Supplements. Vitamin B6, calcium and magnesium supplements, and herbal remedies are not supported by consistent or compelling evidence of efficacy. ACOG conditionally recommends calcium supplementation of 100-200 mg/d in adults to help manage physical and affective symptoms.

A small study suggested that supplemental zinc may improve both physical and psychological symptoms.

Cognitive-behavioral therapy. This treatment aims to interrupt negative and irrational thought patterns and may include awareness and education, as well as relaxation techniques, problem-solving and coping skills, and stress management. It has been associated with small to moderate improvement in anxiety and depression, said Ireland.

Peer support. Patients should consider joining a support group. The International Association for Premenstrual Disorders can help patients connect and develop coping skills.

The bottom line is that people with strong symptomatic evidence of PMDD should have medical intervention — to the benefit of their health and quality of life. Screening for PMDD should be part of women’s wellness examinations, said Ireland. “The impact of PMDD should not be minimized or dismissed,” said Haque. “And patients need to know there are very effective treatments.”

Ireland and Haque had no competing interests with regard to their comments.

TOPLINE:

Fetuses exposed in utero to SARS-CoV-2 are not at an increased risk for neurodevelopmental problems in early childhood.

METHODOLOGY:

• This prospective study aimed to assess whether in utero exposure to SARS-CoV-2, which causes COVID-19, is associated with abnormal neurodevelopment among children at ages 12, 18, and 24 months.
• It included 2003 pregnant individuals (mean age, 33.3 years) from the ASPIRE cohort who were enrolled before 10 weeks’ gestation and followed through 24 months post partum; 10.8% of them were exposed to SARS-CoV-2 during pregnancy, as determined via self-reported data or dried blood spot cards.
• The birth mothers were required to complete the Ages & Stages Questionnaires, Third Edition (ASQ-3), a validated screening tool for neurodevelopmental delays, at 12, 18, and 24 months postpartum.
• Neurodevelopmental outcomes were available for 1757, 1522, and 1523 children at ages 12, 18, and 24 months, respectively.
• The primary outcome was a score below the cutoff on the ASQ-3 across any of the following developmental domains: Communication, gross motor, fine motor, problem-solving, and social skills.

TAKEAWAY:

• The prevalence of abnormal ASQ-3 scores did not differ between children who were exposed to SARS-CoV-2 in utero and those who were not, at ages 12 (P = .39), 18 (P = .58), and 24 (P = .45) months.
• No association was observed between in utero exposure to SARS-CoV-2 and abnormal ASQ-3 scores among children in any of the age groups.
• The lack of an association between exposure to SARS-CoV-2 during pregnancy and abnormal neurodevelopment remained unchanged even when factors such as preterm delivery and the sex of the infant were considered.
• Supplemental analyses found no difference in risk based on the trimester of infection, presence of fever, or incidence of breakthrough infection following vaccination.

IN PRACTICE:

“In this prospective cohort study of pregnant individuals and offspring, in utero exposure to maternal SARS-CoV-2 infection was not associated with abnormal neurodevelopmental screening scores of children through age 24 months. These findings are critical considering the novelty of the SARS-CoV-2 virus to the human species, the global scale of the initial COVID-19 outbreak, the now-endemic nature of the virus indicating ongoing relevance for pregnant individuals,” the authors of the study wrote. 

“While the scientific consensus resists a link between in utero COVID-19 exposure and impaired offspring neurodevelopment, the question remains whether societal responses to the pandemic impacted developmental trajectories,” the researchers added. “Certain studies comparing infants from a pandemic cohort with historic controls have raised concerns about lower ASQ-3 scores among children living during the pandemic. Critically, socioeconomic factors influence vulnerability, not only to infection itself but also regarding the ability to deploy resources in times of stress (eg, school closures) to mitigate sources of developmental harm. Our data support this theory, with the observed independent protective association of increasing household income with childhood ASQ-3 scores. Additional research is warranted to clarify the potential impact of societal measures on early development and the differential impact of these measures on different communities.”

LIMITATIONS: 

Limitations of the research included the use of self-reported data and dried blood spot cards for determining exposure to SARS-CoV-2, which may have led to misclassification. The ASQ-3 is a modestly sensitive tool for detecting developmental delays that may have affected the study’s power to detect associations.

SAVANNAH, GEORGIA — One patient with autoimmune myasthenia gravis (MG) has a niece with the same diagnosis, and at least one of his other close relatives may have it too. Another patient with MG lost his father and brother to complications from the disease, while a surviving brother also has it. These two cases, reported at a meeting of nerve/muscle specialists, spotlight one of the mysteries of MG: What role does heredity play in this disorder?

“Clinical familial associations — when transmission appears to be vertical, from parent to offspring — suggest that there is much yet to learn about genetic bases for autoimmunity and how certain mutations could favor selection for specific immune disorders,” said Elena Shanina, MD, PhD, a neurology professor at the University of Texas Medical Branch, Galveston, in an interview. She and colleagues presented the two case reports at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.

As Shanina noted, MG is usually sporadic without a link to heredity. However, she said, research suggests that up to 7% of patients have MG in their family history.

“There are well-described genetic causes for congenital myasthenic syndromes, in which mutations occur in genes for neuromuscular junction (NMJ) proteins affecting NMJ function. However, much less is known about genetic associations to autoimmune MG,” she said.

“More than a decade ago, differences in HLA DQ haplotype-associated presentation of AChR alpha-chain peptides were suggested to suffice in producing MG, and specific HLA DQ susceptibility links were found predisposing to MG. More recent studies have tried to identify specific genes such as CTLA4 mutations that enhance autoimmunity and neuroinflammation.”
 

Two Cases

In one of the case reports, a 75-year-old White man with hereditary coagulopathy presented with myasthenic crisis in the setting of acute pulmonary embolism. Chronic symptoms included diplopia, ptosis, and proximal muscle weakness.

A niece of the patient has been diagnosed with MG and suffers from ocular symptoms. Meanwhile, an uncle has ptosis but no diagnosis yet, and a daughter has dermatomyositis. Like MG, dermatomyositis is an autoimmune disease that causes muscle weakness.

The patient, who’s CTLA4 negative, is faring well on eculizumab after failing standard therapies, Shanina said.

In the other case, a 67-year-old Hispanic man presented with diplopia, generalized fatigue, and weakness. Like the other patient, he was seropositive for acetylcholine receptor antibodies.

This patient lost his father and brother to complications from MG. Another brother, who’s still living, also has MG.

“The patient has minimal manifestation status with disease and is currently controlled using oral immunomodulatory therapies,” Shanina said. “He is also CTLA4 negative.”
 

Genetics and Environment May Each Play a Role

Shanina called for research exploring mutations and inheritance patterns in families with MG.

“If there are genetic causes that increase autoimmunity with specific propensity for certain immune diseases, correcting those mutations could fundamentally change how we treat — and prevent — at least some autoimmune diseases,” she said. “For example, if HLA linkage is directly involved in determining susceptibility to MG, and if the presence of a specific HLA locus allele is sufficient to produce disease, HLA gene editing could be a future therapy to prevent such diseases. Likewise, monoclonal antibodies that target products of genes that increase risk for autoimmunity might be able to reduce such risks without modifying the patient’s genome.”

Henry J. Kaminski, MD, professor of neurology at George Washington University, Washington, DC, is familiar with the report’s findings. In an interview, he noted that while genetic profiles can make MG more likely, “the situation is not like Huntington’s or Alzheimer’s where there is a strong genetic risk.” 

Instead, he said, there’s “a genetic risk coupled to some environmental stimulus that leads to the development of MG, which is true for many complex autoimmune conditions.” 

While he doesn’t think the two new case reports are especially noteworthy, Kaminski said “the ability to assess genetic risk factors across patients will elucidate understanding of MG. Personalized medicine choices will likely require understanding of genetic risks.”

While understanding MG in families is “always good to know from a research perspective,” there’s no reason to launch surveillance of relatives to see if they also have the disease, he said.

Also, Kaminski cautioned that it’s important to differentiate autoimmune MG from congenital myasthenia, an even more rare genetic disorder of neuromuscular transmission. “Congenital myasthenias will not improve with immune therapy, and patients will suffer complications for no reason,” he said. “A patient who is seronegative should be assessed for congenital myasthenia with the right clinical presentation. The condition would be more likely in patients with a family history of symptoms similar to MG. It may be symptomatic at birth, but patients may present in adulthood.”

Kaminski noted that his team is collecting saliva samples from patients with MuSK-MG, a rare MG subtype linked to more severe cases, for genetic testing and genome-wide association studies.

There was no study funding, and the authors have no disclosures. Kaminski is principal investigator of a rare disease network dedicated to MG.

AMSTERDAM — Prurigo nodularis (PN), an itchy, highly symptomatic disease that can cause severe impairments in quality of life, may gain a third therapy if promising data on povorcitinib presented at the European Academy of Dermatology and Venereology (EADV) 2024 Congress are further validated.

“We now have a pipeline of clinical studies in PN. Who would have even thought that a few years ago,” said Shawn Kwatra, MD, professor and chair, Department of Dermatology, University of Maryland School of Medicine, Baltimore. That is a remarkable turn of events for a difficult disease, he added.

Dr. Kwatra

Dupilumab, a monoclonal antibody that inhibits the activity of interleukin (IL)–4 and IL-13, was the first treatment approved for PN by the Food and Drug Administration 2 years ago. Approval of nemolizumab, a monoclonal antibody that targets IL-31, a cytokine strongly implicated in the itch response, followed in August 2024. Povorcitinib, which targets Janus kinase 1 (JAK1), is on track to be the third.

New data on both nemolizumab and povorcitinib were presented in late breaking news sessions at EADV.

For povorcitinib, a JAK inhibitor, Dr. Kwatra presented extended phase 2 results through 40 weeks at a late-breaker session at the EADV meeting. They follow 16-week data from a randomized study presented earlier this year.

Of the 146 patients followed in the original 16-week randomized trial, which compared 15, 45, and 75 mg of oral povorcitinib once daily against placebo, 126 entered an extension in which all patients were treated with active therapy. In this single-blind phase, those who were responders at 16 weeks received 45 mg povorcitinib, and those who were nonresponders received 75 mg povorcitinib.

At 16 weeks, all doses were superior to placebo in achieving at least a 4-point reduction on the Itch Numerical Rating Scale (NRS4) and the Investigator Global Assessment (IGA) score 0 or 1 (clear or almost clear), as well as in a composite endpoint of both. However, even though the lowest dose of povorcitinib was active, there was a “very clear dose response” demonstrated in speed of response and proportion of responders, according to Dr. Kwatra.

On the 75-mg dose, the time to improvement was a median of 19 days, while the median times to improvement were 35 days on the 45-mg dose and 58 days on the 15-mg dose.

Among povorcitinib responders, 96% had met the NRS4 response at the time they entered the extension study. During the extension study, the proportion of responders who maintained this level of itch control hovered around 90% for the duration. The proportion was 89% at week 40.

The proportion of responders at 16 weeks achieving IGA 0/1, signifying clear or almost clear, was 93%. Again, the rate hovered around 90% for the full 40 weeks. At week 40, the proportion at this outcome was also 89%. The composite outcome among responders persisted at about 80% for most of the follow-up but fell to 63% at the last follow-up.

Among nonresponders who transitioned to 75 mg povorcitinib for the extension period, the NSR4 response rates climbed within 4 weeks to approximately 60% and reached 70% at week 40. For the endpoint of IGA 0/1, rates rose incrementally among the nonresponders over time, reaching 51% at week 40. The composite endpoint was reached at 40 weeks by 41% of nonresponders switched to 75 mg during the 24-week extension.

The results at 40 weeks were highly encouraging, according to Dr. Kwatra, who reported there were no surprises in regard to safety during the extension period. He reported some transient reductions in hemoglobin and infections that resolved, but there were no cardiac events or other more serious events that have been previously associated with JAK inhibitors during the 40-week study period.

When asked if there might be an advantage for povorcitinib relative to the monoclonal antibodies in regard to speed of onset, Dr. Kwatra said that there are no comparative data. Like previous experience with dupilumab, some patients responded rapidly with povorcitinib, but others took longer to achieve benefit.

This variability in response is consistent with the growing evidence that PN is a heterogeneous disease, according to Dr. Kwatra. With multiple up-regulated cytokines implicated in the pathogenesis of PN, he suggested that more treatment options would be useful. When it comes to the multiple molecular pathways involved in the pathogenesis of PN, he said, “patients can be at a different edge of a spectrum.”

In other evidence suggesting that more options are needed, another late-breaking news study at the 2024 EADV congress underlined the fact that PN is a chronic disease. Presented by Franz J. Legat, MD, professor of dermatology at the Medical University of Graz, Graz, Austria, the data involved a withdrawal evaluation nested in a long-term extension (LTE) of the OLYMPIA pivotal trials with nemolizumab.

After 52 weeks in the LTE, 34 patients entered the OLYMPIA DURABILITY study, in which they were randomized to withdrawal or to continue on nemolizumab on an every 4-week dosing schedule.

The relapse rate over 24 weeks was 16.7% (3 of 18 patients) in the continuous nemolizumab arm and 75% (12 of 16 patients) in the withdrawal arm. The median time to relapse was 112.5 days for those in the withdrawal arm and was not reached during follow-up in the nemolizumab arm.

Praising the patients who were willing to risk PN relapse by entering this randomized trial, Dr. Legat said that the study shows a relatively high risk for relapse within months of treatment withdrawal even after good PN control over a period of 52 weeks.

“These data clearly support continuous nemolizumab beyond 52 weeks,” he said.

Dr. Kwatra reported financial relationships with AbbVie, Arcutis, Biotherapeutics, Aslan, Celldex, Galderma, Genzada, Johnson & Johnson, Novartis, Pfizer, Regeneron, Sanofi, and Incyte, which is developing povorcitinib for PN. Dr. Legat reported financial relationships with Almirall, Celgene, Eli Lilly, Menlo Therapeutics, Novartis, Pfizer, Trevi, Vifor, and Galderma, which provided funding for the nemolizumab studies.

“We now have a pipeline of clinical studies in PN. Who would have even thought that a few years ago,” said Shawn Kwatra, MD, professor and chair, Department of Dermatology, University of Maryland School of Medicine, Baltimore. That is a remarkable turn of events for a difficult disease, he added.

Dr. Kwatra

Dupilumab, a monoclonal antibody that inhibits the activity of interleukin (IL)–4 and IL-13, was the first treatment approved for PN by the Food and Drug Administration 2 years ago. Approval of nemolizumab, a monoclonal antibody that targets IL-31, a cytokine strongly implicated in the itch response, followed in August 2024. Povorcitinib, which targets Janus kinase 1 (JAK1), is on track to be the third.

New data on both nemolizumab and povorcitinib were presented in late breaking news sessions at EADV.

For povorcitinib, a JAK inhibitor, Dr. Kwatra presented extended phase 2 results through 40 weeks at a late-breaker session at the EADV meeting. They follow 16-week data from a randomized study presented earlier this year.

Of the 146 patients followed in the original 16-week randomized trial, which compared 15, 45, and 75 mg of oral povorcitinib once daily against placebo, 126 entered an extension in which all patients were treated with active therapy. In this single-blind phase, those who were responders at 16 weeks received 45 mg povorcitinib, and those who were nonresponders received 75 mg povorcitinib.

At 16 weeks, all doses were superior to placebo in achieving at least a 4-point reduction on the Itch Numerical Rating Scale (NRS4) and the Investigator Global Assessment (IGA) score 0 or 1 (clear or almost clear), as well as in a composite endpoint of both. However, even though the lowest dose of povorcitinib was active, there was a “very clear dose response” demonstrated in speed of response and proportion of responders, according to Dr. Kwatra.

On the 75-mg dose, the time to improvement was a median of 19 days, while the median times to improvement were 35 days on the 45-mg dose and 58 days on the 15-mg dose.

Among povorcitinib responders, 96% had met the NRS4 response at the time they entered the extension study. During the extension study, the proportion of responders who maintained this level of itch control hovered around 90% for the duration. The proportion was 89% at week 40.

The proportion of responders at 16 weeks achieving IGA 0/1, signifying clear or almost clear, was 93%. Again, the rate hovered around 90% for the full 40 weeks. At week 40, the proportion at this outcome was also 89%. The composite outcome among responders persisted at about 80% for most of the follow-up but fell to 63% at the last follow-up.

Among nonresponders who transitioned to 75 mg povorcitinib for the extension period, the NSR4 response rates climbed within 4 weeks to approximately 60% and reached 70% at week 40. For the endpoint of IGA 0/1, rates rose incrementally among the nonresponders over time, reaching 51% at week 40. The composite endpoint was reached at 40 weeks by 41% of nonresponders switched to 75 mg during the 24-week extension.

The results at 40 weeks were highly encouraging, according to Dr. Kwatra, who reported there were no surprises in regard to safety during the extension period. He reported some transient reductions in hemoglobin and infections that resolved, but there were no cardiac events or other more serious events that have been previously associated with JAK inhibitors during the 40-week study period.

When asked if there might be an advantage for povorcitinib relative to the monoclonal antibodies in regard to speed of onset, Dr. Kwatra said that there are no comparative data. Like previous experience with dupilumab, some patients responded rapidly with povorcitinib, but others took longer to achieve benefit.

This variability in response is consistent with the growing evidence that PN is a heterogeneous disease, according to Dr. Kwatra. With multiple up-regulated cytokines implicated in the pathogenesis of PN, he suggested that more treatment options would be useful. When it comes to the multiple molecular pathways involved in the pathogenesis of PN, he said, “patients can be at a different edge of a spectrum.”

In other evidence suggesting that more options are needed, another late-breaking news study at the 2024 EADV congress underlined the fact that PN is a chronic disease. Presented by Franz J. Legat, MD, professor of dermatology at the Medical University of Graz, Graz, Austria, the data involved a withdrawal evaluation nested in a long-term extension (LTE) of the OLYMPIA pivotal trials with nemolizumab.

After 52 weeks in the LTE, 34 patients entered the OLYMPIA DURABILITY study, in which they were randomized to withdrawal or to continue on nemolizumab on an every 4-week dosing schedule.

The relapse rate over 24 weeks was 16.7% (3 of 18 patients) in the continuous nemolizumab arm and 75% (12 of 16 patients) in the withdrawal arm. The median time to relapse was 112.5 days for those in the withdrawal arm and was not reached during follow-up in the nemolizumab arm.

Praising the patients who were willing to risk PN relapse by entering this randomized trial, Dr. Legat said that the study shows a relatively high risk for relapse within months of treatment withdrawal even after good PN control over a period of 52 weeks.

“These data clearly support continuous nemolizumab beyond 52 weeks,” he said.

Dr. Kwatra reported financial relationships with AbbVie, Arcutis, Biotherapeutics, Aslan, Celldex, Galderma, Genzada, Johnson & Johnson, Novartis, Pfizer, Regeneron, Sanofi, and Incyte, which is developing povorcitinib for PN. Dr. Legat reported financial relationships with Almirall, Celgene, Eli Lilly, Menlo Therapeutics, Novartis, Pfizer, Trevi, Vifor, and Galderma, which provided funding for the nemolizumab studies.
