Prospective algorithm favors vaginal hysterectomy
based on data from a prospective study of 365 patients.
“Total vaginal hysterectomy is the most cost-effective route, with a low complication rate, and, therefore, should be performed when feasible,” wrote Jennifer J. Schmitt, DO, of the Mayo Clinic, Rochester, Minn., and colleagues.
However, algorithms to support the decision to choose vaginal hysterectomy are not widely used, they said.
To assess the optimal surgical route for hysterectomy, the researchers devised a prospective algorithm and decision tree based on history of laparotomy, uterine size, and vaginal access. The results of their study were published in Obstetrics & Gynecology.
The study population included 365 women aged 18 years and older who underwent hysterectomies between Nov. 24, 2015, and Dec. 31, 2017, at a single center. A total of 202 patients (55%) met criteria for a total vaginal hysterectomy using the algorithm, and 57 (15.6%) were assigned to have an examination under anesthesia followed by total vaginal hysterectomy, for a total of 259 expected vaginal hysterectomies. Ultimately, 211 (81.5%) of the patients identified as being the best candidates for having a vaginal hysterectomy underwent the procedure. Almost all of the procedures – 99.1% – were completed successfully.
The algorithm predicted that 52 patients were expected to have an examination under anesthesia followed by a robot-assisted total laparoscopic hysterectomy and 54 were expected to have an abdominal, robotic, or laparoscopic hysterectomy. A total of 46 procedures (44 robotic, when vaginal was expected and 2 abdominal, when vaginal was expected) deviated to a more invasive route than prescribed by the algorithm, and 7 procedures deviated from the algorithm-predicted robotic or abdominal procedure to total vaginal hysterectomy.
Approximately 95% of the patients were discharged within 24 hours of surgery. These patients included 7 who had vaginal surgery when a more invasive method was predicted and did not experience intraoperative complications or Accordion grade 3 complications.
“Prospective algorithm use predicts that 55.3% of all hysterectomies were expected to have an a priori total vaginal hysterectomy, which is higher than the actual total vaginal hysterectomy rate of 11.5% reported previously,” the researchers noted, and they added that vaginal hysterectomy would be associated with cost savings of $657,524 if the total hysterectomy rate was 55% instead of 11%.
The study findings were limited by several factors including an expertise bias at the center where the study was conducted, as well as the small number of patients with algorithm deviations or poor outcomes, and the lack of a control group, the researchers noted. However, the results support the use of the algorithm “in combination with educating gynecologic surgeons about the feasibility of vaginal surgery,” they said.
“Prospective use of this algorithm nationally may increase the rate of total vaginal hysterectomy and decrease health care delivery costs,” they concluded.
“The American College of Obstetricians and Gynecologists continues to recommend vaginal hysterectomy as the approach of choice whenever feasible, and although clinical evidence and societal endorsements support vaginal hysterectomy as a superior high-value modality, the rate of vaginal hysterectomy in the United States has continued to decline,” Arnold P. Advincula, MD, of Columbia University Medical Center, New York, wrote in an accompanying editorial.
Many variables beyond clinical will determine the optimal hysterectomy route, Dr. Advincula said.
“Although historical evidence demonstrates that vaginal hysterectomy is associated with better outcomes when compared with other approaches, a multitude of studies now exist that challenge this notion. Given the financial implications and overall costs of care with surgical complications and 30-day readmissions, experienced high-volume surgeons using all available routes have shown robotics to be the best surgical approach in terms of fewer postoperative complications and lowest 30-day readmission rates,” he noted. However, “one should not split hairs and subtly pit one minimally invasive option against another, but instead should work toward the goal of minimizing laparotomy, which is still performed at a high rate,” Dr. Advincula emphasized.
The study was supported in part by the National Center for Advancing Translational Science. Dr. Schmitt had no financial conflicts to disclose. Dr. Advincula disclosed serving as a consultant for AbbVie, Baxter, ConMed, Eximis Surgical, Intuitive Surgical, and Titan Medical, and performing consultancy work and receiving royalties from Cooper Surgical.

Physicians and health systems can reduce fear around COVID-19
A message from a Chief Wellness Officer
We are at a time, unfortunately, of significant public uncertainty and fear of “the coronavirus.” Mixed and inaccurate messages from national leaders in the setting of delayed testing availability have heightened fears and impeded a uniformity in responses, medical and preventive.
Despite this, physicians, nurses, and other health professionals across the country, and in many other countries, have been addressing the medical realities of this pandemic in a way that should make every one of us health professionals proud – from the Chinese doctors and nurses to the Italian intensivists and primary care physicians throughout many countries who have treated patients suffering from, or fearful of, a novel disease with uncertain transmission characteristics and unpredictable clinical outcomes.
It is now time for physicians and other health providers in the United States to step up to the plate and model appropriate transmission-reducing behavior for the general public. This will help reduce the overall morbidity and mortality associated with this pandemic and let us return to a more normal lifestyle as soon as possible. Physicians need to be reassuring but realistic, and there are concrete steps that we can take to demonstrate to the general public that there is a way forward.
First the basic facts. The United States does not have enough intensive care beds or ventilators to handle a major pandemic. We will also have insufficient physicians and nurses if many are quarantined. The tragic experience in Italy, where patients are dying from lack of ventilators, intensive care facilities, and staff, must not be repeated here.
Many health systems are canceling or reducing outpatient appointments and increasingly using video and other telehealth technologies, especially for assessing and triaging people who believe that they may have become infected and are relatively asymptomatic. While all of the disruptions may seem unsettling, they are actually good news for those of us in healthcare. Efforts to “flatten the curve” will slow the infection spread and help us better manage patients who become critical.
So, what can physicians do?
- Make sure you are getting good information about the situation. Access reliable information and data that are widely available through the Centers for Disease Control and Prevention, the National Institutes of Health, and the World Health Organization. Listen to professional news organizations, local and national. Pass this information to your patients and community.
- Obviously, when practicing clinically, follow all infection control protocols, which will inevitably change over time. Make it clear to your patients why you are following these protocols and procedures.
- Support and actively promote the public health responses to this pandemic. Systematic reviews of the evidence base have found that isolating ill persons, testing and tracing contacts, quarantining exposed persons, closing schools and workplaces, and avoiding crowding are more effective if implemented immediately, simultaneously (ie, school closures combined with teleworking for parents), and with high community compliance.
- Practice social distancing so that you remain as much in control as you can. This will make you feel psychologically better and safer, as well as reduce the risk for transmission. Take the essential precautionary measures that we are all being asked to take. Wash your hands. Do not shake hands. Clean shared items. Do not go to large public gatherings. Minimize large group travel as much as you can. Use video to see your patients or your own doctor.
- Connect and reconnect with people you trust and love. See your family, your partner, your children, your friends. Speak to them on the phone and nourish those relationships. See how they feel and care for each other. They will be worried about you. Reassure them. Be in the moment with them and use the importance of these relationships to give yourself a chance not to overthink any fears you might have.
- Look after yourself physically. Physical fitness is good for your mental health. While White House guidelines suggest avoiding gyms, you can still enjoy long walks and outdoor activities. Take the weekend off and don’t work excessively. Sleep well – at least 7-8 hours. which has a series of really excellent meditation and relaxation tools.
- Do not panic. Uncertainty surrounding the pandemic makes all of us anxious and afraid. It is normal to become hypervigilant, especially with our nonstop media. It is normal to be concerned when we feel out of control and when we are hearing about a possible future catastrophe, especially when fed with differing sets of information from multiple sources and countries.
- Be careful with any large decisions you are making that may affect the lives of yourself and your loved ones. Think about your decisions and try to take the long view; and run them by your spouse, partner, or friends. This is not a time to be making sudden big decisions that may be driven unconsciously, in part at least, by fear and anxiety.
- Realize that all of these societal disruptions are actually good for us in health care, and they help your family and friends understand the importance of slowing the disease’s spread. That’s good for health care and good for everyone.
Finally, remember that “this is what we do,” to quote Doug Kirk, MD, chief medical officer of UC Davis Health. We must look after our patients. But we also have to look after ourselves so that we can look after our patients. We should all be proud of our work and our caring. And we should model our personal behavior to our patients and to our families and friends so that they will model it to their community networks. That way, more people will keep well, and we will have more chance of “flattening the curve” and reducing the morbidity and mortality associated with COVID-19.

Benefit of ultrathin over thin stent still growing at 3 years
NATIONAL HARBOR, MD. – In a head-to-head comparison, the ultrathin-strut Orsiro drug-eluting stent (DES) is demonstrating a growing advantage over the thin-strut Xience DES stent in stable patients undergoing coronary revascularization, according to a presentation at the 2020 CRT meeting.
“These results direct our attention to strut thickness and polymer composition as key attributes for stent design,” reported David E. Kandzari, MD, director of interventional cardiology at the Piedmont Heart Institute in Atlanta.
In the multinational BIOFLOW V trial, 1,334 patients were randomized in a two-to-one ratio to the Orsiro stent, which is composed of a bioabsorbable, sirolimus-eluting polymer, or to the Xience stent, which is composed of an everolimus-eluting durable polymer. Relative to the Xience device, which has thin struts of 81 microns in width, the struts of the Orsiro device, at 60 microns in width, are characterized as ultrathin.
In earlier published follow-up studies, the ultrathin device demonstrated a lower rate of target lesion (TL) failure at 1 year (5.9% vs. 9.2%; P = .032) and at 2 years (7.1% vs. 11.1%; P = .015), but the 3-year data are notable because they indicate that the relative advantage is continuing to grow, according to Dr. Kandzari.
At 3 years, with follow-up available for 94.8% and 94.2% of the Orsiro and Xience groups, respectively, the absolute relative difference in the primary endpoint of TL failure reached 5.4% (8.2% vs. 13.6%; P = .002) in favor of the Orsiro device.
For the components of the composite TL failure endpoint, which includes cardiovascular death, TL-related myocardial infarction, and TL revascularization, there were large relative advantages for every outcome except cardiovascular death, which did not differ between the Orsiro and Xience groups (1.1% vs. 1.2%, respectively; P = .1). Conversely, the TL-related MI (5.5% vs. 10.1%; P = .004) and ischemia-driven TL revascularization (3.4% vs. 6.9%; P = .008) rates were nearly cut in half in the Orsiro arm.
“The benefit appears to be bimodal in that there is a significant advantage in the periprocedural period [for the Orsiro device] and then a late advantage,” Dr. Kandzari reported.
Most TL-related MI in both groups, for example, occurred within the first 30 days of follow-up. Although there was a relative advantage for the Orsiro device in this early period (4.1% vs. 6.7%; P = .04), Dr. Kandzari indicated that the advantage between 30 days and 3 years was even more impressive (0.95% vs. 2.8%; P = .012).
Dr. Kandzari, showing a graph in which the line representing Orsiro device hugged the x axis as the line for the Xience device climbed, emphasized that the rate of target vessel MI at the end of follow-up was nearly three times greater for those randomized to the Xience device.
The patterns of ischemia-driven TL revascularization also diverged. In this case, the rates over the first 360 days were very similar for the two devices initially. At 1 year, the lower rate in the Orsiro device was not significantly different (2.0% vs. 2.3%; P = .72), but the lines began to separate at about 18 months. By the end of 3 years, the rate of ischemia-related TL revascularization was nearly 70% lower in the Orsiro arm (1.5% vs. 4.7%; P < .001).
The Orsiro device was also linked with a lower rate of definite or probable stent thrombosis when the two devices were compared from 30 days post implantation to 3 years of follow-up (0.1% vs. 1.2%; P = .018).
Noting that there are several features of the Orsiro device that might explain these results, including the width of the struts, the biodegradable polymer, and the type of anti-inflammatory coating, Dr. Kandzari said that it is difficult to determine which attributes account for the overall or the specific advantages observed for the Orsiro device in the BIOFLOW V trial.
However, he hypothesized that “there might be different time lines for different benefits” related to individual device characteristics. For example, the ultrathin struts might be important for the early relative advantages while the biodegradation of the strut might explain the reduced need for revascularization.
Overall, “there is an emerging evidence base consistent across clinical trials demonstrating a potential efficacy and safety difference in favor of ultrathin struts,” according to Dr. Kandzari.
The data are “remarkable,” according to James B. Hermiller, MD, an interventional cardiologist at the Heart Center of Indiana in Indianapolis. A panel member for the CRT late-breaking trial session where these data were presented, Dr. Hermiller was impressed by the very low rate of revascularization in the extended follow-up.
“We have all wanted to see a flattening of these event curves after a year,” Dr. Hermiller said. He indicated that the BIOFLOW V data represent a departure from the need for revascularization and other late events so commonly seen over lengthening follow-up with earlier generation devices.

NATIONAL HARBOR, MD. – In a head-to-head comparison, the ultrathin-strut Orsiro drug-eluting stent (DES) is demonstrating a growing advantage over the thin-strut Xience DES stent in stable patients undergoing coronary revascularization, according to a presentation at the 2020 CRT meeting.
“These results direct our attention to strut thickness and polymer composition as key attributes for stent design,” reported David E. Kandzari, MD, director of interventional cardiology at the Piedmont Heart Institute in Atlanta.
In the multinational BIOFLOW V trial, 1,334 patients were randomized in a two-to-one ratio to the Orsiro stent, which is composed of a bioabsorbable, sirolimus-eluting polymer, or to the Xience stent, which is composed of an everolimus-eluting durable polymer. Relative to the Xience device, which has thin struts of 81 microns in width, the struts of the Orsiro device, at 60 microns in width, are characterized as ultrathin.
In earlier published follow-up studies, the ultrathin device demonstrated a lower rate of target lesion (TL) failure at 1 year (5.9% vs. 9.2%; P = .032) and at 2 years (7.1% vs. 11.1%; P = .015), but the 3-year data are notable because they indicate that the relative advantage is continuing to grow, according to Dr. Kandzari.
At 3 years, with follow-up available for 94.8% and 94.2% of the Orsiro and Xience groups, respectively, the absolute relative difference in the primary endpoint of TL failure reached 5.4% (8.2% vs. 13.6%; P = .002) in favor of the Orsiro device.
For the components of the composite TL failure endpoint, which includes cardiovascular death, TL-related myocardial infarction, and TL revascularization, there were large relative advantages for every outcome except cardiovascular death, which did not differ between the Orsiro and Xience groups (1.1% vs. 1.2%, respectively; P = .1). Conversely, the TL-related MI (5.5% vs. 10.1%; P = .004) and ischemia-driven TL revascularization (3.4% vs. 6.9%; P = .008) rates were nearly cut in half in the Orsiro arm.
“The benefit appears to be bimodal in that there is a significant advantage in the periprocedural period [for the Orsiro device] and then a late advantage,” Dr. Kandzari reported.
Most TL-related MI in both groups, for example, occurred within the first 30 days of follow-up. Although there was a relative advantage for the Orsiro device in this early period (4.1% vs. 6.7%; P = .04), Dr. Kandzari indicated that the advantage between 30 days and 3 years was even more impressive (0.95% vs. 2.8%; P = .012).
Dr. Kandzari, showing a graph in which the line representing Orsiro device hugged the x axis as the line for the Xience device climbed, emphasized that the rate of target vessel MI at the end of follow-up was nearly three times greater for those randomized to the Xience device.
The patterns of ischemia-driven TL revascularization also diverged. In this case, the rates over the first 360 days were very similar for the two devices initially. At 1 year, the lower rate in the Orsiro device was not significantly different (2.0% vs. 2.3%; P = .72), but the lines began to separate at about 18 months. By the end of 3 years, the rate of ischemia-related TL revascularization was nearly 70% lower in the Orsiro arm (1.5% vs. 4.7%; P < .001).
The Orsiro device was also linked with a lower rate of definite or probable stent thrombosis when the two devices were compared from 30 days post implantation to 3 years of follow-up (0.1% vs. 1.2%; P = .018).

REPORTING FROM CRT 2020
FDA advises stopping SGLT2 inhibitor treatment prior to surgery
The new changes affect canagliflozin, dapagliflozin, empagliflozin, and ertugliflozin, and were made because surgery may put patients being treated with SGLT2 inhibitors at a higher risk of ketoacidosis. Canagliflozin, dapagliflozin, and empagliflozin should be discontinued 3 days before scheduled surgery, and ertugliflozin should be stopped at least 4 days before, the agency noted in a press release. Blood glucose should be monitored after drug discontinuation and appropriately managed before surgery.
“The SGLT2 inhibitor may be restarted once the patient’s oral intake is back to baseline and any other risk factors for ketoacidosis are resolved,” the agency added.
SGLT2 inhibitors lower blood sugar by causing the kidney to remove sugar from the body through urine. Side effects for the drugs vary, but include urinary tract infections and genital mycotic infection. Patients with severe renal impairment or end-stage renal disease, who are on dialysis treatment, or who have a known hypersensitivity to the medication should not take SGLT2 inhibitors, the FDA said.

Teledermoscopy using smartphones fails to boost skin cancer detection
Skin cancer detection does not improve when patients use a dermatoscope for smartphones to capture and send photos of lesions for diagnosis, according to the Australian SKIN Project trial.
“Mobile health applications are increasingly used in cancer prevention and early detection but rarely tested stringently for their value with regard to patient care,” noted trial investigators, who were led by Monika Janda, PhD, of the University of Queensland in Brisbane, Australia. The trial was published in Lancet Digital Health.
The investigators studied 234 adults at high risk for skin cancer, asking them to perform whole-body skin self-exams in their homes at baseline, 1 month, and 2 months.
Half of patients were randomized to perform standard naked-eye exams, note suspicious lesions on a body chart, and submit the chart by email. The other half were randomized to supplement their exams with mobile dermoscopy, and they were provided with a dermatoscope (FotoFinder) that interfaces with smartphones to capture and submit photos of suspicious lesions to a dermatologist for telediagnosis.
Both groups received Web-based instructions on how to complete whole-body skin self-exams and were examined in person within 3 months of their last self-exam to provide a reference standard.
In comparing the two approaches for early detection of skin cancer, the investigators determined that teledermoscopy-enhanced exams would have to show 20% greater sensitivity to establish their superiority.
The median number of lesions submitted was six per person in both the group using adjunctive teledermoscopy and the group performing only naked-eye exams.
At the lesion level, teledermoscopy-enhanced exams had lower sensitivity than naked-eye exams in detecting suspected skin cancers or precursor lesions (75% vs. 88%; P = .04) and similar specificity (87% vs. 89%; P = .42). At the patient level, the two approaches had statistically indistinguishable sensitivity (87% vs. 97%; P = .26) and specificity (95% vs. 96%; P = .96).
At the same time, telediagnosis showed good overall diagnostic concordance with in-person clinical skin examination (88%).
“For the early detection of skin cancer, naked-eye skin self-examination should continue to be recommended by cancer agencies,” Dr. Janda and colleagues concluded. “Further improvements to the instructions for participants on the relevance of nonpigmented skin lesions, training for partners, and the integration of automatic algorithms that rule out clearly benign skin lesions at the time of photographing might increase sensitivity of teledermoscopy in the future.”
This trial was funded by the National Health and Medical Research Council. The authors disclosed relationships with e-derm-consult, SciBase, Canfield Scientific, and other companies.

Study links GLP-1R agonists, lower inflammatory biomarker levels
Patients with both type 2 diabetes and asthma who were on glucagonlike peptide receptor–1 (GLP-1R) agonists for glucose control had lower levels of a key biomarker of airway inflammation than similar patients on other types of glucose-control medications, according to results of a study to have been presented at the annual meeting of the American Academy of Asthma, Allergy, and Immunology. The AAAAI canceled their annual meeting and provided abstracts and access to presenters for press coverage.
The findings from this study potentially replicated findings in humans that have been reported in preclinical trials.
“Our work showed that type 2 diabetics with asthma who were treated with GLP-1 receptor agonists had lower levels of periostin, and this provides really one of the first human data to show that these drugs may impact key inflammation pathways in the airway,” Dinah Foer, MD, of Brigham and Women’s Hospital, Boston, said in an interview. She described periostin as “a known critical inducer of airway mucous production and airway responsiveness.”
The study retrospectively evaluated serum samples from the Partners HealthCare Biobank of 161 adults with both asthma and type 2 diabetes, 42 of whom were on GLP-1R agonists and 119 of whom were taking non-GLP-1R agonist diabetes medications. The study used the Partners Healthcare EHR to identify eligible patients.
The study found that periostin levels were significantly decreased in GLP-1R agonist users: 19.1 ng/mL (standard deviation, +8.7) versus 27.4 ng/mL (SD, +14) in the non-GLP-1R agonist group (P = .001), Dr. Foer said. The other known mediators of asthma inflammatory pathways that were measured – interleukin-6, IL-8, sCD163, total IgE, and sST2 (soluble suppression of tumorigenesis–2) – showed no differences between the two groups, Dr. Foer said.
She said that this was the first human study to show similar results to preclinical models of asthma pathways. “What was interesting to us was that our findings were robust even when we controlled for covariates,” she added.
These findings lay the groundwork for further research into the potential therapeutic role GLP-1R agonists in asthma, Dr. Foer said. “This supports using periostin as a biomarker for novel therapeutic use of GLP-1R [agonists] in asthma,” she said. “At this point further study is needed to understand the clinical impact of GPL-1R [agonists] in asthma both for patients with type 2 diabetes and potentially in the future for patients who don’t have type 2 diabetes or metabolic disease.”
She added: “I don’t think we’re there yet; this is just one foot forward.”
The next step for researchers involves analyzing outcomes in asthmatics with type 2 diabetes on GLP-1R agonist therapy using a larger sample size as well as patients with asthma and metabolic disease, Dr. Foer said. The goal would be to identify corresponding biomarkers.
“There’s a terrific conversation in the field about the relationships between metabolism and asthma,” she said. “What our data contributes to that is, it suggests a role for metabolic pathways, specifically as it’s related GLP-1R [agonist] signaling pathways in regulating airway inflammation.”
Mark Moss, MD, associate professor of allergy & immunology at the University of Wisconsin–Madison, who was to serve as the moderator of the session, was positive about the GLP-1R agonist findings. He said in an interview: “This is promising research that provides a possible new target for the treatment of asthma.”
Dr. Foer disclosed that she has no relevant financial relationships.

While prior studies have shown the effects of racial/ethnic and socioeconomic risk factors on treatment outcomes in adult cancer populations, less is known about how these factors impact children with CNS cancers, explained study author Robert Fineberg, MD, of St. Anthony North Health Campus in Westminster, Colo., and colleagues.
The authors conducted their study to examine the effects of demographic and socioeconomic factors on survival in pediatric CNS cancers. Using data from the Surveillance, Epidemiology, and End Results database, the researchers identified 1,881 patients with CNS tumors, including both spinal and cranial neoplasms.
Data collection encompassed patient characteristics, socioeconomic parameters, tumor characteristics, treatment, and year of diagnosis. The primary outcomes were overall survival and disease stage at diagnosis.
Most patients were white (78.15%) and non-Hispanic (72.09%). The most common brain tumors were gliomas (n = 788), ependymomas (n = 418), and medulloblastomas (n = 393).
On multivariable analysis, the researchers found that black and Hispanic patients had worse survival, compared with white patients (hazard ratio, 1.39; P = .0014) and non-Hispanic patients (HR, 1.36; P = .0002).
After adjustment for socioeconomic parameters and treatment, the hazard ratios for both Hispanic (HR, 1.29; P = .0051) and black patients (HR, 1.29; P = .0206) slightly declined, but the differences remained significant.
On stratified analysis, poorer survival rates were observed for black and Hispanic patients with both metastatic and localized disease at diagnosis, compared with white non-Hispanic patients. However, after adjustment for mediating factors, the difference did not remain significant for black patients (P = .1026).
“Our findings on extent of disease at diagnosis demonstrated that neither black race nor Hispanic ethnicity increased the chance of metastatic disease at presentation when controlling for mediating variables,” the authors wrote. “These data suggest that racial and ethnic disparities appear to be partially explained by postdiagnosis mediating factors that may fall in the pathway between race/ethnicity and poorer survival.”
The researchers acknowledged that a key limitation of this study was the exclusion of insurance status because of incomplete access for some patients. As a result, potential associations between insurance and survival or extent of disease could not be determined.
“To better understand underlying causes that contribute to the disparity of outcomes in pediatric brain tumors, patient-level data should be utilized in future studies to investigate both biological factors and pre/postdiagnosis treatment gaps in the care of children diagnosed with CNS tumors in the hopes of improving outcomes,” the authors wrote.
In the meantime, collaboration among physicians could help improve outcomes for these patients, according to study author Adam Green, MD, of the University of Colorado at Denver in Aurora.
“[Clinicians] should establish good working relationships with pediatric oncology and neuro-oncology physicians in their community, and they should ask questions early of those teams when they have patients they’re concerned about,” Dr. Green said. “They can [ensure] that patients of minority race/ethnicity, nonprivate health insurance, and lower socioeconomic status have easy and timely access to appointments.”
This research was supported, in part, by grant funding from the National Institutes of Health. The authors reported having no conflicts of interest.

SLIT tablet during pollen season improves symptoms of allergic rhinitis
according to recent research released as an abstract for the annual meeting of the American Academy of Allergy, Asthma & Immunology.
Tree pollen season is generally considered to be between February and June, with alder and hazel allergens affecting patients early and oak pollen affecting patients later in the season. Since a major birch allergen, Betula verrucosa 1 (Bet v 1), cross-reacts with alder, hazel, and oak allergens, some patients may experience allergies across the entire tree pollen season from members of this so-called birth homologous group, Hendrik Nolte, MD, senior vice president of research and development at ALK-Abello Americas and International, said in an interview.
According to the U.S. National Health and Nutrition Examination Survey 2005-2006, 16% of 8,086 participants 6 years or older with allergy had a specific immunoglobulin E (IgE) to birch, while 18% had a specific IgE to oak. Patients who reported having hay fever had a specific IgE to birch of 23% and a specific IgE to oak of 26% (J Allergy Clin Immunol. 2011 May;127[5]:1226-1235.e7).
“Patients who are allergic to birch pollen often experience symptoms in response to pollen from other members of the birch homologous group, which prolong the tree season and increase the symptom burden for these patients,” Dr. Nolte said. “Thus, treatment with SLIT-tablet immunotherapy may be an important treatment option for many allergy sufferers.”
Dr. Nolte and colleagues performed a randomized, double-blind, multinational trial of 634 patients before and during tree pollen season in which participants received a daily SLIT tablet or placebo. Patients were between ages 12 and 65 years with allergic rhinitis, and investigators enrolled patients or without conjunctivitis and with or without asthma. The investigations evaluated the patients’ daily symptom score and daily medication score, which was grouped into the total combined score. The patients were also allowed to use their rescue medications during the trial.
SLIT demonstrates symptom improvement
“Improvement in allergic rhinoconjunctivitis symptoms and reduction in symptom-relieving medication use with the tree SLIT-tablet during birch, alder/hazel, and oak pollen seasons were significant versus placebo and showed internal consistency across almost 4 months of birch and related tree pollen exposure,” Dr. Nolte said.
Patients showed relative improvements in their total combined score of 39.6% for birch, 29.7% for alder and hazel, 36.0% during oak pollen season, and 35.0% during the entire tree pollen season, compared with placebo (all P ≤ .002). Relative daily symptom scores also improved in the group that received oral SLIT, with 36.8% of patients showing improvement during birch season, 26.0% during alder and hazel season, 31.6% during oak season, and 31.6% across all pollen seasons, compared with those taking placebo (all P ≤ .003). A greater number of patients also achieved a relative improvement in daily medication score during birch season (49.2%), alder and hazel season (43.8%), oak season (45.9%) and during the whole of tree pollen season (45.3%), compared with placebo (P ≤ .002).
“The results support the clinical relevance of cross-reactivity between birch, alder/hazel, and oak pollen homologous allergens,” Dr. Nolte said. “Immunologic cross-reactivity is supported by alder, hazel, and oak specific IgE data and IgG4 in responses to the tree SLIT tablet.”
Dr. Nolte said the next step in his team’s research was to evaluate oral SLIT in a phase 3 trial for children aged 5-17 years.
This study was funded by ALK, and the authors received medical writing and editorial assistance from Scott Medical Communications. Dr. Nolte reported that he is a paid employee of ALK.

African Americans with SLE face increased risk of CVD hospitalizations
PHOENIX – African Americans with systemic lupus erythematosus are more likely to experience recurrent hospitalizations for cardiovascular disease, compared with other racial/ethnic groups, results from a single-state registry study found.
“SLE is an autoimmune disease that causes inflammation affecting multiple organ systems including the cardiovascular system,” Meghan Angley, MPH, said at the Epidemiology and Prevention/Lifestyle and Cardiometabolic Health meeting. “Therefore, individuals with SLE are at risk for early CVD. African Americans represent the racial group at greatest risk for SLE.”
According to Ms. Angley, with the department of epidemiology at Emory University, Atlanta, white women with SLE have CVD associated mortality 12 years earlier than their non-SLE counterparts, while African American women with SLE have CVD-associated mortality 19 years earlier than their non-SLE counterparts. “We know that recurrent hospitalizations for CVD are associated with mortality,” she said. “These represent potential points of identification of high-risk individuals and also points of interventions.”
In order to study racial disparities across recurrent hospitalizations for cardiovascular disease in an SLE population, Ms. Angley and her colleagues drew from the Georgia Lupus Registry, which is a population-based registry of patients with validated SLE in two Georgia counties. They included all cases diagnosed between 2000 and 2004. The registry was linked to records of all inpatient hospitalizations in Georgia between 2000 and 2013. The researchers used ICD-9 codes to identify hospitalizations for coronary heart disease, peripheral artery disease, cerebrovascular disease, and heart failure and used the Prentice-Williams-Peterson model for recurrent time-to-event analysis. Specifically, they looked at the total time scale from the point of diagnosis to each of the subsequent CVD hospitalizations and truncated the number of hospitalizations at three to maintain stable modeling estimates. The analysis was censored at the time of patient death or at the end of 2013 and adjusted for sex and age at diagnosis.
The sample included 417 African Americans with SLE and 149 non–African Americans with the disease. Most (86%) were female, and the non–African American group was slightly more likely to have been diagnosed with SLE after the age of 45 years, compared with the African American group (36% vs. 30%, respectively).
Ms. Angley and her colleagues found that 24% of African Americans had at least one CVD hospitalization, and 14% had at least two, while 13% of non–African Americans had at least one CVD hospitalization, and 5% had at least two. Among those in the African American group, reasons for hospitalizations were congestive heart failure, (58%), cerebrovascular disease (27%), coronary heart disease (18%), and peripheral artery disease (2%). Among those in the non–African American group, reasons for hospitalizations were congestive heart failure (38%), coronary heart disease (38%), cerebrovascular disease (25%), and peripheral artery disease (6%).
Overall, African American race was associated with recurrent hospitalizations (adjusted hazard ratio, 1.9). In an event-specific stratified analysis, the association between African American race and the hazard of recurrence became even more pronounced with each event (hospitalization 1 aHR, 1.2; hospitalization 2 aHR, 1.5; hospitalization 3 aHR, 1.9). The researchers also observed that African Americans were hospitalized sooner, compared with non–African Americans: a median of 3.68 versus 4.61 years for hospitalization 1, 3.73 years versus 5.98 years for hospitalization 2, and 4.84 years versus 8.14 years for hospitalization 3.
“African Americans with SLE are more likely to experience recurrent hospitalizations for CVD,” Ms. Angley concluded at the meeting, which was sponsored by the American Heart Association. “The events occur sooner after diagnosis than in non–African Americans, suggesting that African Americans may be more vulnerable to the cardiovascular complications of SLE. Our next steps include examining potential reasons for these disparities, such as looking at primary care patterns over time, SLE severity over time, and treatment at CVD hospitalizations.”
In an interview, one of the meeting session’s moderators, Sherry-Ann Brown, MD, called for additional research to determine the reasons for disparities that were observed between African Americans with SLE and their non–African American counterparts. “We need to figure out why and address it,” said Dr. Brown, who is a cardiologist and physician-scientist at Mayo Clinic, Rochester, Minn. “We recognize that social determinants of health, such as insurance, socioeconomic factors, and psychosocial factors, can contribute. We need to figure out the additional steps we need to take in order to close that gap.”
Ms. Angley reported having no disclosures. The study was funded by grants from the Centers for Disease Control and Prevention and by the National Institutes of Health.

“African Americans with SLE are more likely to experience recurrent hospitalizations for CVD,” Ms. Angley concluded at the meeting, which was sponsored by the American Heart Association. “The events occur sooner after diagnosis than in non–African Americans, suggesting that African Americans may be more vulnerable to the cardiovascular complications of SLE. Our next steps include examining potential reasons for these disparities, such as looking at primary care patterns over time, SLE severity over time, and treatment at CVD hospitalizations.”
In an interview, one of the meeting session’s moderators, Sherry-Ann Brown, MD, called for additional research to determine the reasons for disparities that were observed between African Americans with SLE and their non–African American counterparts. “We need to figure out why and address it,” said Dr. Brown, who is a cardiologist and physician-scientist at Mayo Clinic, Rochester, Minn. “We recognize that social determinants of health, such as insurance, socioeconomic factors, and psychosocial factors, can contribute. We need to figure out the additional steps we need to take in order to close that gap.”
Ms. Angley reported having no disclosures. The study was funded by grants from the Centers for Disease Control and Prevention and by the National Institutes of Health.

PARAGON-HF: Optimal systolic pressure in HFpEF is 120-129 mm Hg
A target systolic blood pressure (SBP) of 120-129 mm Hg in patients with heart failure with preserved ejection fraction proved to be the sweet spot with the lowest rates of major adverse cardiovascular and renal events in a new analysis from the landmark PARAGON-HF trial.
This finding from the largest-ever randomized, controlled study in heart failure with preserved ejection fraction (HFpEF) strengthens support for current U.S. joint hypertension guidelines, which call for a target SBP less than 130 mm Hg in patients with HFpEF (J Am Coll Cardiol. 2017 Aug 8;70[6]:776-803), a recommendation based upon weak evidence until now. That’s because the SPRINT trial, the major impetus for adoption of intensive blood pressure control in the current guidelines, excluded patients with symptomatic HF, Scott D. Solomon, MD, and coinvestigators noted in their new analysis. The study was published in the Journal of the American College of Cardiology and had been planned for presentation during the joint scientific sessions of the American College of Cardiology and the World Heart Federation. ACC organizers chose to present parts of the meeting virtually after COVID-19 concerns caused them to cancel the meeting.
The new analysis from PARAGON-HF (Prospective Comparison of ARNI with ARB Global Outcomes in HFpEF) also ruled out the SBP-lowering effect of sacubitril/valsartan (Entresto) as the explanation for the combination drug’s demonstrated beneficial impact on outcomes in the subgroup with an SBP of 120-129 mm Hg. That wasn’t actually a surprise. Indeed, the new study had two hypotheses: one, that the relationship between SBP and cardiovascular and renal outcomes in HFpEF would follow a J-shaped curve, and two, that sacubitril/valsartan’s blood pressure–lowering effect would not account for the drug’s outcome benefits in the subset of HFpEF patients with an SBP in the sweet spot of 120-129 mm Hg. Both hypotheses were borne out, noted Dr. Solomon, professor of medicine at Harvard Medical School and director of noninvasive cardiology at Brigham and Women’s Hospital, both in Boston.
“These data strongly support that additional mechanisms other than blood pressure–lowering account for the benefit. But this is not surprising. The same can be said for most of the therapies that work in heart failure,” he said in an interview.
Take, for example, spironolactone. In TOPCAT (Treatment of Preserved Cardiac Function Heart Failure with an Aldosterone Antagonist), another major trial in which Dr. Solomon played a leadership role, the beneficial effect of spironolactone on clinical outcomes also proved unrelated to the drug’s blood pressure–lowering effect.
Other known effects of sacubitril/valsartan, a novel angiotensin receptor–neprilysin inhibitor, or ARNI, might in theory account for the observed clinical benefits in ARNI-treated patients with an on-treatment SBP of 120-129 mm Hg in PARAGON-HF. These include improved left atrial remodeling, an increase in natriuretic peptides, and improved myocardial relaxation. However, the current lack of understanding of the basic mechanistic processes underlying the varied clinical expressions of HFpEF is a major factor contributing to the lack of any proven-effective therapy for this extremely common and costly disorder, according to Dr. Solomon and coinvestigators.
In contrast to HFpEF, for which to date there is no proven treatment, heart failure with reduced ejection fraction sacubitril/valsartan has a class I recommendation on the strength of its performance in significantly reducing cardiovascular deaths and heart failure hospitalizations in the PARADIGM-HF trial (N Engl J Med. 2014 Sep 11;371:993-1004).
PARAGON-HF included 4,822 patients with symptomatic HFpEF who were randomized to sacubitril/valsartan at 97/103 mg b.i.d. or valsartan at 160 mg b.i.d. As previously reported (N Engl J Med. 2019 Oct 24;381[17]:1609-20), at an average follow-up of 35 months, the primary outcome – a composite of total hospitalizations for heart failure and cardiovascular death – occurred at a rate of 12.8 events per 100 patient-years in the sacubitril/valsartan group and 14.6 per 100 patient-years in the valsartan arm, for a 13% relative risk reduction that narrowly missed statistical significance (P = .059).
However, sacubitril/valsartan showed significant benefit on some prespecified secondary endpoints, including worsening renal function, change in New York Heart Association class, and quality of life. Women, who notably accounted for 52% of study participants, appeared to benefit from sacubitril/valsartan more than men as evidenced by their 27% relative risk reduction in the primary endpoint. Also, in the roughly half of PARAGON-HF participants with a baseline left ventricular ejection fraction of 45%-57%, treatment with sacubitril/valsartan resulted in a statistically significant 22% relative risk reduction in the primary endpoint, compared with valsartan alone.
SBP and cardiovascular outcomes in HFpEF
In the new analysis, Dr. Solomon and coworkers examined outcomes based on baseline and mean achieved SBP quartiles regardless of treatment arm. In an unadjusted analysis, the primary composite endpoint occurred at a rate of 15.2 events/100 patient-years in HFpEF patients with an achieved SBP below 120 mm Hg, 11.4/100 patient-years at 120-129 mm Hg, 12.2/100 patient-years at 130-139 mm Hg, and 15.6/100 patient-years at 140 mm Hg or more. Further, in a multivariate regression analysis extensively adjusted for atrial fibrillation, sex, race, and numerous other potential confounders, the group with an achieved SBP of 120-129 mm Hg continued to fare best. The adjusted risks for the primary endpoint were 11% and 21% higher in patients in the first and third quartiles of achieved SBP, compared with those at 120-129 mm Hg, although neither trend reached statistical significance. But patients in the top quartile, with an achieved SBP of 140 mm Hg or more, had a highly significant 56% increase in risk, compared with patients in the second-lowest SBP quartile.
Change in blood pressure from baseline to week 48 had no impact on quality of life or high-sensitivity troponin T. However, each 10–mm Hg lowering of SBP was associated with a modest 2.1% reduction in log-transformed N-terminal of the prohormone brain natriuretic peptide.
Sacubitril/valsartan reduced SBP by an average of 5.2 mm Hg more than valsartan alone at 4 weeks regardless of baseline SBP. And the combo drug had a significantly greater SBP-lowering effect in women than men, by a margin of 6.3 mm Hg versus 4.0 mm Hg. But a Cox regression analysis showed that in women, as in the study population as a whole, sacubitril/valsartan’s SBP-lowering effects didn’t account for the drug’s impact on outcomes.
In an editorial accompanying publication of the new PARAGON-HF blood pressure analysis (J Am Coll Cardiol. 2020 Mar 16. doi: 10.1016/j.jacc.2020.02.024), Hector O. Ventura, MD, and colleagues at the Ochsner Clinic in New Orleans observed that the study results “lend some credence to the prognostic relationship of blood pressure in HFpEF, but whether they should serve as a therapeutic target or are merely a prognostic surrogate determined by other pathogenic factors, such as vascular ventricular uncoupling or aortic stiffness on one hand when blood pressure is greater than 140 mm Hg, or a reduced cardiac performance indicated by reduced blood pressure to less than 120 mm Hg, remains uncertain.”
“What is certain, however, is that the relationship and contributions of hypertension in manifest HFpEF are complex, multifactorial and likely go well beyond a simplistic framework of hemodynamic influences,” they added.
Dr. Solomon has received research grants from and serves as a consultant to Novartis, which funded PARAGON-HF, and has similar financial relationships with more than a dozen other pharmaceutical companies. Dr. Ventura reported having no relevant financial interests.
