LISBON – A shift toward broader-spectrum antibiotics and increasing antibiotic resistance has led to high levels of mortality and neurodevelopmental impacts in surviving babies, according to a large international study conducted on four continents.

Results of the 3-year study were presented at this week’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID).

The observational study, NeoOBS, conducted by the Global Antibiotic Research and Development Partnership (GARDP) and key partners from 2018 to 2020, explored the outcomes of more than 3,200 newborns, finding an overall mortality of 11% in those with suspected neonatal sepsis. The mortality rate increased to 18% in newborns in whom a pathogen was detected in blood culture.

More than half of infection-related deaths (59%) were due to hospital-acquired infections. Klebsiella pneumoniae was the most common pathogen isolated and is usually associated with hospital-acquired infections, which are increasingly resistant to existing antibiotic treatments, said a report produced by GARDP to accompany the results.

The study also identified a worrying trend: Hospitals are frequently using last-line agents such as carbapenems because of the high degree of antibiotic resistance in their facilities. Of note, 15% of babies with neonatal sepsis were given last-line antibiotics.

Pediatrician Julia Bielicki, MD, PhD, senior lecturer, Paediatric Infectious Diseases Research Group, St. George’s University of London, and clinician at the University of Basel Children’s Hospital, Switzerland, was a coinvestigator on the NeoOBS study.

In an interview, she explained that, as well as reducing mortality, the research is about managing infections better to prevent long-term events and improve the quality of life for survivors of neonatal sepsis. “It can have life-changing impacts for so many babies,” Dr. Bielicki said. “Improving care is much more than just making sure the baby survives the episode of sepsis – it’s about ensuring these babies can become children and adults and go on to lead productive lives.”

Also, only a minority of patients (13%) received the World Health Organization guidelines for standard of care use of ampicillin and gentamicin, and there was increasing use of last-line agents such as carbapenems and even polymyxins in some settings in low- and middle-income countries. “This is alarming and foretells the impending crisis of a lack of antibiotics to treat sepsis caused by multidrug-resistant organisms,” according to the GARDP report.

There was wide variability in antibiotic combinations used across sites in Bangladesh, Brazil, China, Greece, India, Italy, Kenya, South Africa, Thailand, Uganda, and Vietnam, and often such use was not supported by underlying data.

Dr. Bielicki remarked that there was a shift toward broad-spectrum antibiotic use. “In a high-income country, you have more restrictive patterns of antibiotic use, but it isn’t necessarily less antibiotic exposure of neonates to antibiotics, but on the whole, usually narrow-spectrum agents are used.”

In Africa and Asia, on the other hand, clinicians often have to use a broader-spectrum antibiotic empirically and may need to switch to another antibiotic very quickly. “Sometimes alternatives are not available,” she pointed out.

“Local physicians are very perceptive of this problem of antibiotic resistance in their daily practice, especially in centers with high mortality,” said Dr. Bielicki, emphasizing that it is not their fault, but is “due to the limitations in terms of the weapons available to treat these babies, which strongly demonstrates the growing problem of antimicrobial resistance affecting these babies on a global scale.”

Tim Jinks, PhD, Head of Drug Resistant Infections Priority Program at Wellcome Trust, commented on the study in a series of text messages to this news organization. “This research provides further demonstration of the urgent need for improved treatment of newborns suffering with sepsis and particularly the requirement for new antibiotics that overcome the burden of drug-resistant infections caused by [antimicrobial resistance].”

“The study is a hugely important contribution to our understanding of the burden of neonatal sepsis in low- and middle- income countries,” he added, “and points toward ways that patient treatment can be improved to save more lives.”
 

High-, middle-, and low-income countries

The NeoOBS study gathered data from 19 hospitals in 11 high-, middle-, and low-income countries and assessed which antibiotics are currently being used to treat neonatal sepsis, as well as the degree of drug resistance associated with them. Sites included some in Italy and Greece, where most of the neonatal sepsis data currently originate, and this helped to anchor the data, Dr. Bielicki said.

The study identified babies with clinical sepsis over a 4-week period and observed how these patients were managed, particularly with respect to antibiotics, as well as outcomes including whether they recovered, remained in hospital, or died. Investigators obtained bacterial cultures from the patients and grew them to identify which organisms were causing the sepsis.

Of note, mortality varied widely between hospitals, ranging from 1% to 27%. Dr. Bielicki explained that the investigators were currently exploring the reasons behind this wide range of mortality. “There are lots of possible reasons for this, including structural factors such as how care is delivered, which is complex to measure,” she said. “It isn’t trivial to measure why, in a certain setting, mortality is low and why in another setting of comparable income range, mortality is much higher.”

Aside from the mortality results, Dr. Bielicki also emphasized that the survivors of neonatal sepsis frequently experience neurodevelopmental impacts. “A hospital may have low mortality, but many of these babies may have neurodevelopment problems, and this has a long-term impact.”

“Even though mortality might be low in a certain hospital, it might not be low in terms of morbidity,” she added.

The researchers also collected isolates from the cohort of neonates to determine which antibiotic combinations work against the pathogens. “This will help us define what sort of antibiotic regimen warrants further investigation,” Dr. Bielicki said.

Principal Investigator, Mike Sharland, MD, also from St. George’s, University of London, who is also the Antimicrobial Resistance Program Lead at Penta Child Health Research, said, in a press release, that the study had shown that antibiotic resistance is now one of the major threats to neonatal health globally. “There are virtually no studies underway on developing novel antibiotic treatments for babies with sepsis caused by multidrug-resistant infections.”

“This is a major problem for babies in all countries, both rich and poor,” he stressed.
 

NeoSep-1 trial to compare multiple different treatments

The results have paved the way for a major new global trial of multiple established and new antibiotics with the goal of reducing mortality from neonatal sepsis – the NeoSep1 trial.

“This is a randomized trial with a specific design that allows us to rank different treatments against each other in terms of effectiveness, safety, and costs,” Dr. Bielicki explained.

Among the antibiotics in the study are amikacin, flomoxef and amikacin, or fosfomycin and flomoxef in babies with sepsis 28 days old or younger. Similar to the NeoOBS study, patients will be recruited from all over the world, and in particular from low- and middle-income countries such as Kenya, South Africa, and other countries in Africa and Southeast Asia.

Ultimately, the researchers want to identify modifiable risk factors and enact change in practice. But Dr. Bielicki was quick to point out that it was difficult to disentangle those factors that can easily be changed. “Some can be changed in theory, but in practice it is actually difficult to change them. One modifiable risk factor that can be changed is probably infection control, so when resistant bacteria appear in a unit, we need to ensure that there is no or minimal transmission between babies.”

Luregn Schlapbach, MD, PhD, Head, department of intensive care and neonatology, University Children’s Hospital Zurich, Switzerland, welcomed the study, saying recent recognition of pediatric and neonatal sepsis was an urgent problem worldwide.

She referred to the 2017 WHO resolution recognizing that sepsis represents a leading cause of mortality and morbidity worldwide, affecting patients of all ages, across all continents and health care systems but that many were pediatric. “At that time, our understanding of the true burden of sepsis was limited, as was our knowledge of current epidemiology,” she said in an email interview. “The Global Burden of Disease study in 2020 revealed that about half of the approximatively 50 million global sepsis cases affect pediatric age groups, many of those during neonatal age.”

The formal acknowledgment of this extensive need emphasizes the “urgency to design preventive and therapeutic interventions to reduce this devastating burden,” Dr. Schlapbach said. “In this context, the work led by GARDP is of great importance – it is designed to improve our understanding of current practice, risk factors, and burden of neonatal sepsis across low- to middle-income settings and is essential to design adequately powered trials testing interventions such as antimicrobials to improve patient outcomes and reduce the further emergence of antimicrobial resistance.”

Dr. Bielicki and Dr. Schlapbach have disclosed no relevant financial relationships.

The latest upward trend in new COVID-19 cases among children picked up steam, but there was also some movement in the vaccination effort in the past week.

Moderna submitted a request to the Food and Drug administration for emergency use authorization of its COVID-19 vaccine in children under the age of 6 years, according to this news organization, and Pfizer/BioNTech officially applied for authorization of a booster dose in children aged 5-11, the companies announced.

The FDA has tentatively scheduled meetings of its Vaccines and Related Biological Products Advisory Committee in June to consider the applications, saying that it “understands the urgency to authorize a vaccine for age groups who are not currently eligible for vaccination and will work diligently to complete our evaluation of the data. Should any of the submissions be completed in a timely manner and the data support a clear path forward following our evaluation, the FDA will act quickly” to convene the necessary meetings.

The need for greater access to vaccines seems to be increasing, as new pediatric COVID cases rose for the third consecutive week. April 22-28 saw over 53,000 new cases reported in children, up 43.5% from the previous week and up 105% since cases started rising again after dipping under 26,000 during the week of April 1-7, based on data from the American Academy of Pediatrics and the Children’s Hospital Association.

Hospital admissions involving diagnosed COVID also ticked up over the latter half of April, although the most recent 7-day average (April 24-30) of 112 per day was lower than the 117 reported for the previous week (April 17-23), the Centers for Disease Control and Prevention said, also noting that figures for the latest week “should be interpreted with caution.”

Vaccinations also were up slightly in children aged 5-11 years, with 52,000 receiving their first dose during the week of April 21-27, compared with 48,000 the week before. There was a slight dip, however, among 12- to 17-year-olds, who received 34,000 first doses during April 21-27, versus 35,000 the previous week, the AAP said in a separate report.

Cumulatively, almost 69% of all children aged 12-17 years have received at least one dose of the COVID-19 vaccine and 59% are fully vaccinated. Those aged 5-11 are well short of those figures, with just over 35% having received at least one dose and 28.5% fully vaccinated, the CDC said on its COVID Data Tracker.

A look at recent activity shows that children are not gaining on adults, who are much more likely to be vaccinated – full vaccination in those aged 50-64, for example, is 80%. During the 2 weeks from April 17-30, the 5- to 11-year-olds represented 10.5% of those who had initiated a first dose and 12.4% of those who gained full-vaccination status, both of which were well below the oldest age groups, the CDC reported.

The World Health Organization and United Nations International Children’s Emergency Fund are warning about a heightened risk of measles spreading and triggering larger outbreaks in 2022.

Worldwide cases are up nearly 80% so far over 2021, the groups reported. More than 17,300 measles cases were reported worldwide in January and February, compared with 9,600 cases at the beginning of 2021.

In the last 12 months, there have been 21 “large and disruptive” measles outbreaks, particularly in Africa and the East Mediterranean region. The actual numbers are likely higher because of underreporting and disruptions to surveillance systems.

“Pandemic-related disruptions, increasing inequalities in access to vaccines, and the diversion of resources from routine immunization are leaving too many children without protection against measles and other vaccine-preventable diseases,” the organizations said.

As cities and countries relax COVID-19 restrictions, measles outbreaks are becoming more likely, they noted.

“It is encouraging that people in many communities are beginning to feel protected enough from COVID-19 to return to more social activities. But doing so in places where children are not receiving routine vaccination creates the perfect storm for the spread of a disease like measles,” Catherine Russell, executive director for UNICEF, said in the statement.

In the past year, the largest measles outbreaks have occurred in Somalia, Yemen, Nigeria, Afghanistan, and Ethiopia. The main reason for outbreaks is a lack measles vaccine coverage, the organizations said.

About 23 million children missed childhood vaccinations in 2020, the groups said. Childhood vaccination campaigns were hindered because of the COVID-19 pandemic and conflicts in Ukraine, Ethiopia, Somalia, and Afghanistan.

Overall, 57 campaigns targeting vaccine-preventable diseases across 43 countries that were scheduled to take place since the beginning of the COVID-19 pandemic are still postponed, the groups said, which could affect 203 million people. Among those, 19 are measles campaigns, which could put 73 million children at risk of measles because of missed vaccinations.

Vaccine coverage of 95% or higher with two doses of the measles vaccine can provide protection, according to the organizations. But the five countries that had the highest measles cases in the last year had first-dose coverage between 46% and 68%.

In the United States, measles vaccinations in kindergarten students dropped from about 95% to 93.9% for the 2020-2021 school year, according to CNN.

Vaccination coverage also dropped from 95% to 93.6% for diphtheria, tetanus, acellular pertussis, and varicella. Even though the decreases appear small, it means tens of thousands of children across the United States started school without their common childhood vaccinations, the Centers for Disease Control and Prevention said.

“We are concerned that missed routine vaccinations could leave children vulnerable to preventable diseases like measles and whooping cough, which are extremely contagious and can be very serious, especially for babies and young children,” Shannon Stokley, DrPH, deputy director of the CDC’s immunization services division, told CNN.

The numbers show a “concerning decline in childhood immunizations that began in March 2020,” she said.

Health officials are investigating at least 30 cases of severe hepatitis in children across 10 U.S. states. The Minnesota Department of Health received two reports of severe hepatitis, one in an infant and another in a 2-year-old, the Associated Press reported on April 30. One child was treated “several months ago” and required a liver transplant, according to the article. 

Worldwide cases surpass 200, including 34 cases in the United Kingdom, the U.K. Health Security Agency announced on April 29. Most cases have occurred in the United Kingdom, but there have been more than 55 probable and confirmed hepatitis cases in children in 12 countries in the European Union or the European Economic Area. Cases have also been identified in Asia, with both Japan and Singapore reporting one case each of acute hepatitis, Bloomberg reported. Additionally, three children in Indonesia died from acute hepatitis in April, but the total number of cases in that country was not available.

Although the total number of worldwide cases remains small, the severity of the cases – as well as their unexplained cause – have health officials on alert, said David Lee Thomas, MD, MPH, of the Viral Hepatitis Center at Johns Hopkins Medicine in Baltimore. “There are some kids who would have died if not for liver transplants.”

In the United States, the only confirmed cases are in Alabama, where nine patients were admitted for severe hepatitis between October 2021 and February 2022. Beyond the two suspected cases in Minnesota, health officials are investigating at least 19 other potential cases in eight states, according to NBC News: Delaware (1), Georgia, Illinois (3), Louisiana (1), New York, North Carolina (2), Tennessee (6), and Wisconsin (4). (New York and Georgia did not specify the number of cases being investigated.)

Reported cases have occurred in patients aged between 1 month and 16 years old. Globally, at least 17 patients have needed liver transplants, according to a World Health Organization alert on April 23. While WHO officials said there has been at least one death globally linked to hepatitis, that does not include the three deaths in Indonesia. One death has also been reported in Wisconsin, but the state’s Department of Health Services did not confirm whether this death was included in the WHO announcement.

The cause of these severe hepatitis cases has yet to be identified, but these cases have tested negative for more common viruses that can cause hepatitis in children. There is no link between these cases and COVID-19 vaccination, according to WHO, because most affected children have not been vaccinated.

Adenovirus is a possible contributing factor in these cases, as many of the cases in Europe tested positive for the virus. In an analysis of the nine Alabama cases released by the Centers for Disease Control and Prevention, adenovirus was detected in the blood samples of all nine children. Five of the nine children tested positive for adenovirus type 41, which is a common cause of acute gastroenteritis in children. While the six liver biopsies performed showed varying degrees of hepatitis, there were “no viral inclusions observed, no immunohistochemical evidence of adenovirus, or no viral particles identified by electron microscopy,” according to the report. None of the children tested positive for COVID-19 or had a documented history of previous COVID-19 infection.

“At this time, we believe that adenovirus may be the cause for these reported cases, but other potential environmental and situational factors are still being investigated,” the CDC said in a media statement. The CDC added that the report was specific to the nine Alabama cases, and that the agency is working to investigate other potential cases with state and local public health officials.

While the “growing consensus” among experts is that adenovirus could be behind these severe cases, there are many unanswered questions, Dr. Thomas added, such as why this strain of adenovirus causes such severe hepatitis, and why the liver biopsies do not show classic signs of viral infection. That information will come as investigations continue.

“From a provider point of view, if you have a child with an unexplained liver problem, report it to the CDC,” he advised. “Right now, we have to learn more about [these cases],” and that requires more research like the investigations in Alabama, he noted.

The Diagnosis: Condyloma Latum

A punch biopsy of the perianal mass revealed epidermal acanthosis with elongated slender rete ridges, scattered intraepidermal neutrophils, and a dense dermal inflammatory infiltrate (Figure, A) with a prominent plasma cell component (Figure, B). A treponemal immunohistochemical stain revealed numerous coiled spirochetes concentrated in the lower epidermis (Figure, C). Serologic test results including rapid plasma reagin (titer 1:1024) and Treponema pallidum antibody were reactive, confirming the diagnosis of secondary syphilis with condyloma latum. The patient was treated with intramuscular penicillin G with resolution of the lesion 2 weeks later.

Syphilis, a sexually transmitted infection caused by the spirochete T pallidum, reached historically low rates in the United States in the early 2000s due to the widespread use of penicillin and effective public health efforts.1 However, the rates of primary and secondary syphilis infections recently have markedly increased, resulting in the current epidemic of syphilis in the United States and Europe.^1,2 Its wide variety of clinical and histopathologic manifestations make recognition challenging and lend it the moniker “the great imitator.”

Secondary syphilis results from the systemic spread of T pallidum and classically is characterized by the triad of a skin rash that frequently involves the palms and soles, mucosal ulceration such as condyloma latum, and lymphadenopathy.^2,3 However, condyloma latum may represent the only manifestation of secondary syphilis in a subset of patients,⁴ as observed in our patient.

In the 2 months prior to diagnosis, our patient was evaluated at multiple emergency departments and primary care clinics, receiving diagnoses of condyloma acuminatum, genital herpes simplex virus, hemorrhoids, and suspicion for malignancy—entities that comprise the differential diagnosis for condyloma latum.^2,5 Despite some degree of overlap in patient populations, risk factors, and presentations between these diagnostic considerations, recognition of certain clinical features, in addition to histopathologic evaluation, may facilitate navigation of this differential diagnosis.

Primary and secondary syphilis infections have been predominantly observed in men, mostly men who have sex with men and/or those who are infected with HIV.¹ Condyloma acuminata, genital herpes simplex virus, and chancroid also are seen in younger individuals, more commonly in those with multiple sexual partners, but show a more even gender distribution and are not restricted to those partaking in anal intercourse. The clinical presentation of condyloma latum can be differentiated by its painless, flat, smooth, and commonly hypopigmented appearance, often with associated surface erosion and a gray exudate, in contrast to condyloma acuminatum, which typically presents as nontender, flesh-colored or hyperpigmented, exophytic papules that may coalesce into plaques.^2,3,6 Genital herpes simplex virus infection presents with multiple small papulovesicular lesions with ulceration, most commonly on the tip or shaft of the penis, though perianal lesions may be seen in men who have sex with men.⁷ Similarly, chancroid presents with painful necrotizing genital ulcers most commonly on the penis, though perianal lesions also may be seen.8 Hemorrhoids classically are seen in middle-aged adults with a history of constipation, present with rectal bleeding, and may be associated with pain in the setting of thrombosis or ulceration.⁹ Finally, perianal squamous cell carcinoma primarily occurs in older adults, typically in the sixth decade of life. Verrucous carcinoma most commonly arises in the oropharynx or anogenital region in sites of chronic irritation and presents as a slow-growing exophytic mass. Classic squamous cell carcinoma most commonly occurs in association with human papillomavirus infection and presents with scaly erythematous papules or plaques.¹⁰

Our case highlighted the clinical difficulty in recognizing condyloma latum, as this lesion remained undiagnosed for 2 months, and our patient presumptively was treated for multiple perianal pathologies prior to a biopsy being performed. Due to the clinical similarity of various perianal lesions, the diagnosis of condyloma latum should be considered, and serologic studies should be performed in fitting clinical contexts, especially in light of recently rising rates of syphilis infection.^1,2

A man who worked on a commercial poultry farm in Colorado has tested positive for avian influenza A(H5) virus, better known as H5 bird flu, the CDC announced on April 28.

This is the first case of H5 bird flu in humans in the United States and only the second case in the world, the CDC said in a news release. The first case was detected last December in a man who raised birds in the United Kingdom. That man had no symptoms.

The only symptom the man in Colorado reported was fatigue, the Colorado Department of Public Health and Environment (CDPHE) reported. He has recovered and is isolating and being treated with oseltamivir, an antiviral drug.

The CDC said the man was helping kill poultry that likely had the H5N1 bird flu.

He is a state prison inmate who was working on a commercial poultry farm in Montrose County in a prerelease employment program, the CDPHE said. The flock he was working with has been euthanized, and the response team and other inmates working on the farm were given protective equipment, the CDPHE said.

“Repeat testing on the person was negative for influenza,” the department said. “Because the person was in close contact with infected poultry, the virus may have been in the person’s nose without causing infection.”

This CDC said the case does not change the risk of bird flu for the general public, which is considered low. People who work with birds should continue to take safety precautions, such as wearing gloves when handling birds and avoiding birds that appear to be dead or ill, the CDC said.

“We want to reassure Coloradans that the risk to them is low,” said Rachel Herlihy, MD, state epidemiologist with the CDPHE. “I am grateful for the seamless collaboration between CDC, Department of Corrections, Department of Agriculture, and CDPHE, as we continue to monitor this virus and protect all Coloradans.”

The federal government says the H5N1 virus has been found in commercial and backyard birds in 29 states and in wild birds in 34 states since the first cases were detected in late 2021.

The CDC says it has tracked the health of 2,500 people exposed to birds infected with H5N1 and only found one case of human infection, in Colorado.

A man who worked on a commercial poultry farm in Colorado has tested positive for avian influenza A(H5) virus, better known as H5 bird flu, the CDC announced on April 28.

This is the first case of H5 bird flu in humans in the United States and only the second case in the world, the CDC said in a news release. The first case was detected last December in a man who raised birds in the United Kingdom. That man had no symptoms.

The only symptom the man in Colorado reported was fatigue, the Colorado Department of Public Health and Environment (CDPHE) reported. He has recovered and is isolating and being treated with oseltamivir, an antiviral drug.

The CDC said the man was helping kill poultry that likely had the H5N1 bird flu.

He is a state prison inmate who was working on a commercial poultry farm in Montrose County in a prerelease employment program, the CDPHE said. The flock he was working with has been euthanized, and the response team and other inmates working on the farm were given protective equipment, the CDPHE said.

The incidence of sexually transmitted infection (STI) as well as disability-adjusted life-years (DALYs) increased worldwide over 30 years, according to an observational trend study from China.

“Most countries had a decrease in age-standardized rates of incidence and DALY for STIs, whereas the absolute incident cases and DALYs increased from 1990 to 2019,” the authors write in The Lancet Infectious Diseases. “Therefore, STIs still represent a global public health challenge, especially in sub-Saharan Africa and Latin America, where more attention and health prevention services are warranted.”

“Our study also suggested an upward trend of age-standardized incidence rates among young populations, especially for syphilis, after 2010,” they add.
 

STIs are a major worldwide public health challenge

To assess global STI burden and trends, co–lead study author Yang Zheng, MD, of Zhejiang University School of Medicine in Hangzhou, China, and colleagues analyzed data from the Global Burden of Disease (GBD) study 2019.

They calculated incidence and DALYs of STIs in the general population at national, regional, and global levels over 30 years. They also calculated annual percentage changes in the age-standardized incidence rate and the age-standardized DALY rate of the five STIs included in the GBD study.

Of 204 countries in GBD 2019, 161 provided data on syphilis, 64 on gonorrhea, 94 on chlamydia, 56 on trichomonas, and 77 on genital herpes. The authors included 95% uncertainty intervals (UIs) and used Bayesian meta-regression to model the data.

• Overall, they found that the global age-standardized incidence rate of STIs trended downward, with an estimated annual percentage change of –0.04 (95% UI, –0.08 to 0.00) from 1990 to 2019, reaching 9,535.71 per 100,000 person-years (8,169.73-11,054.76) in 2019.
• The age-standardized DALY rate decreased with an estimated annual percentage change of –0.92 (–1.01 to –0.84) and reached 22.74 per 100,000 person-years (14.37-37.11) in 2019.
• Sub-Saharan Africa, one of the hotspots, had the highest age-standardized incidence rate (19,973.12 per 100,000 person-years, 17,382.69-23,001.57) and age-standardized DALY rate (389.32 per 100,000 person-years, 154.27-769.74).
• The highest incidence rate was among adolescents (18,377.82 per 100,000 person-years, 14,040.38-23,443.31), with stable total STI trends except for an increase in syphilis between 2010 (347.65 per 100,000 person-years, 203.58-590.69) and 2019 (423.16 per 100,000 person-years, 235.70-659.01).
• The age-standardized incidence rate was higher among males (10,471.63 per 100,000 person-years, 8,892.20-12,176.10) than females (8,602.40 per 100,000 person-years, 7,358.00-10,001.18), whereas the age-standardized DALY rate was higher among females (33.31 per 100,000 person-years, 21.05-55.25) than males (12.11 per 100,000 person-years, 7.63-18.93).

The authors deliver a call to action

“This paper is a call to action to focus on the STI pandemic with granular data on key target populations,” Yukari C. Manabe, MD, FIDSA, FRCP, who was not involved in the study, told this news organization. “If behavioral messaging and testing in adolescents is not improved, HIV incidence rates will be impacted, and the gains that have been made in this area will be threatened.”

“Although the number of countries from which data could be culled was limited, the change in incident cases is particularly striking, with most countries showing an increase and with African countries showing the largest rise,” said Dr. Manabe, professor of medicine, international health, and molecular microbiology and immunology at Johns Hopkins Medicine and director of the Johns Hopkins Center for Innovative Diagnostics for Infectious Diseases, Baltimore.

“The increase in syphilis incidence rates, particularly in younger people, including men who have sex with men, is also alarming,” she added in an email. “It is interesting to see the gender gap grow as more countries adopt antenatal syphilis screening.”

Ken S. Ho, MD, MPH, infectious diseases specialist and medical director of the Pitt Men’s Study at the University of Pittsburgh School of Medicine, Pennsylvania, called the study’s findings a wake-up call for clinicians to discuss sexual health and wellness with their patients, to increase STI screening, and to address STI stigma.

“Overall, STI rates in most countries have trended down, but paradoxically, the number of cases may be going up, because we have more younger, sexually actively people,” Dr. Ho said in an email.

“The study helps us understand the populations most impacted by STIs and allows us to design and create public health interventions that target the most impacted communities and demographic groups,” Dr. Ho, who also was not involved in the study, added. “It allows us to reflect on how we address disparities. For example, the greater burden of disease seen in women may be due to the fact that women may not be screened and are diagnosed later.”

Dr. Ho explained that the high STI rates in sub-Saharan Africa and Latin America are thought to be due to factors such as poverty and limited access to health care, known drivers of health care disparities.

The 2016 global incidence of common STIs was estimated to be up to 563.3 million, including 6.3 million cases of syphilis, 86.9 million cases of gonorrhea, 127.2 million cases of chlamydia, 156.0 million cases of trichomonas, and 186.9 million cases of genital herpes, the authors write.

The World Health Organization aims to end the STI epidemic by 2030, they note.

The study was funded by Mega-Project of National Science and Technology for the 13th Five-Year Plan of China and the National Natural Science Foundation of China. The authors, Dr. Manabe, and Dr. Ho have disclosed no relevant financial relationships.

After several cases of acute hepatitis of unknown origin in children in the United Kingdom were reported, further cases have now been reported in France (two cases), Denmark, Ireland, the Netherlands, and Spain. More than 80 cases have been reported overall, raising fears of an epidemic, according to a press release from the European Centre for Disease Prevention and Control (ECDC).

Furthermore, nine cases have allegedly been reported since last autumn in Alabama in the United States. These cases have mainly been in children aged 1-6 years.

Investigations are ongoing in all these countries, particularly as the “exact causes of these cases of acute hepatitis remain unknown.” Nevertheless, the team working on these cases in the United Kingdom believes that, based on clinical and epidemiologic data, the cause is probably infectious in origin.

Coordinated by the ECDC, European medical societies such as the European Association for the Study of the Liver and the European Society of Clinical Microbiology and Infectious Diseases (ESCMID) are working together to promote information sharing, according to the European agency.
 

Potential infectious agent

For context, on April 5, the United Kingdom reported about 10 cases of acute hepatitis of unknown origin in children younger than 10 in Scotland with no underlying conditions. Seven days later, the UK reported that 61 additional cases were under investigation in England, Wales, and Northern Ireland, the majority of which were in children aged 2-5 years.

The cases in the United Kingdom presented with severe acute hepatitis, with increased liver enzyme levels (aspartate aminotransferase [AST] and alanine aminotransferase [ALT] levels above 500 IU/L), and most presented with jaundice. Some reported gastrointestinal symptoms such as abdominal pain, diarrhea, and vomiting in the previous weeks.

The majority had no fever.

Although no deaths had been reported at press time, some cases needed to be seen by a liver specialist in the hospital, and others had to undergo transplantation (six transplants in Europe and two in the United States).

Initial hypotheses have focused on a potential infectious agent or exposure to a toxin. No link to COVID-19 vaccination has been established.
 

Which type of hepatitis?

The ECDC reports that laboratory tests have ruled out the possibility of attributing the cases to type A, B, C, D, and E viral hepatitis. Of the 13 cases in Scotland, 3 tested positive for SARS-CoV-2, 5 were negative, and 2 had contracted COVID-19 over the course of the last 3 months.

One positive test for adenovirus was found in 5 of the 13 Scottish cases, out of the 11 that were tested. All the cases reported in the United States tested positive for an adenovirus, five of which were for adenovirus type 41, which is responsible for inflammation of the bowel. Investigations are ongoing to assess any possible involvement of this virus in other cases. It should be noted that adenoviruses can cause hepatitis in children, but generally only in those who are immunosuppressed.

The pandemic could be another possible explanation, Nancy Reau, MD, head of the hepatology department at Rush University, Chicago, told this news organization. “The possibility that these cases are linked to COVID still exists,” she said. Some cases in the United Kingdom tested positive for COVID-19; none of these children had received the COVID-19 vaccine.

“COVID has been regularly seen to raise liver markers. It has also been shown to affect organs other than the lungs,” she stated. “It could be the case that, as it evolves, this virus has the potential to cause hepatitis in children.”

For context, on April 5, the United Kingdom reported about 10 cases of acute hepatitis of unknown origin in children younger than 10 in Scotland with no underlying conditions. Seven days later, the UK reported that 61 additional cases were under investigation in England, Wales, and Northern Ireland, the majority of which were in children aged 2-5 years.

The cases in the United Kingdom presented with severe acute hepatitis, with increased liver enzyme levels (aspartate aminotransferase [AST] and alanine aminotransferase [ALT] levels above 500 IU/L), and most presented with jaundice. Some reported gastrointestinal symptoms such as abdominal pain, diarrhea, and vomiting in the previous weeks.

The majority had no fever.

Although no deaths had been reported at press time, some cases needed to be seen by a liver specialist in the hospital, and others had to undergo transplantation (six transplants in Europe and two in the United States).

Initial hypotheses have focused on a potential infectious agent or exposure to a toxin. No link to COVID-19 vaccination has been established.
 

Which type of hepatitis?

The ECDC reports that laboratory tests have ruled out the possibility of attributing the cases to type A, B, C, D, and E viral hepatitis. Of the 13 cases in Scotland, 3 tested positive for SARS-CoV-2, 5 were negative, and 2 had contracted COVID-19 over the course of the last 3 months.

One positive test for adenovirus was found in 5 of the 13 Scottish cases, out of the 11 that were tested. All the cases reported in the United States tested positive for an adenovirus, five of which were for adenovirus type 41, which is responsible for inflammation of the bowel. Investigations are ongoing to assess any possible involvement of this virus in other cases. It should be noted that adenoviruses can cause hepatitis in children, but generally only in those who are immunosuppressed.

The pandemic could be another possible explanation, Nancy Reau, MD, head of the hepatology department at Rush University, Chicago, told this news organization. “The possibility that these cases are linked to COVID still exists,” she said. Some cases in the United Kingdom tested positive for COVID-19; none of these children had received the COVID-19 vaccine.

“COVID has been regularly seen to raise liver markers. It has also been shown to affect organs other than the lungs,” she stated. “It could be the case that, as it evolves, this virus has the potential to cause hepatitis in children.”

LISBON – Two-thirds of antibiotic prescriptions written for Black patients and more than half of antibiotic prescriptions for Hispanic/Latinx patients are inappropriate, according to data from a study of antibiotic prescribing habits in U.S. doctors’ offices, hospital clinics, and emergency departments.

Eric Young, PharmD, PhD, from the University of Texas at Austin, and UT Health, San Antonio, presented his work as a poster at the 32nd European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) 2022.

“We were really surprised mainly by the racial findings, because Black patients have the highest overall and the highest inappropriate prescribing of antibiotics,” he told this news organization. “There was also a difference seen for age [across all ethnicities].”

Pediatric patients were found to have high overall prescribing but, notably, the lowest inappropriate prescribing among all the patient groups, reported Dr. Young. “This is interesting because oftentimes we think the more antibiotics are prescribed, then surely the greater the inappropriate prescribing would be too, but pediatricians actually have one of the lowest rates of inappropriate antibiotic prescribing. They do a great job.”

The study included more than 7 billion patient visits, 11.3% of which involved an antibiotic prescription.

The rate of antibiotic prescribing was 122 per 1,000 visits in Black patients and 139 per 1,000 visits in Hispanic patients, while in White patients, the rate was 109 per 1,000 visits. The rate was 114 per 1,000 visits in patients younger than 18 years and 170 per 1,000 visits in females.

Dr. Young found that almost 64% of antibiotic prescriptions written for Black patients and 58% for Hispanic patients were inappropriate. For White patients, the rate of inappropriate antibiotic prescribing was 56%. Similarly, 74% of prescriptions dispensed to patients aged 65 years and older and 58% to males were deemed inappropriate.

Kajal Bhakta, PharmD, BCACP, ambulatory care clinical pharmacist, University Health System, UT Health Science Center San Antonio, who was not involved in the study, pointed out that antibiotics are frequently prescribed without confirmation of an infection, owing to the fact that the verification process may delay care, especially in the outpatient setting.

Dr. Bhakta said that overprescribing in the elderly population and in certain ethnic groups was “likely due to socioeconomic and cultural factors. These prescribing methods may lead to unnecessary drug side effects and/or antimicrobial resistance.”

Regarding the patient-doctor consultation process, she pointed out that “older patients may have trouble describing their symptoms, and when those symptoms remain unresolved, providers may be more inclined to prescribe antibiotics to help.”

Sometimes overprescribing can occur because of the logistics involved in getting to the doctor’s office in the outpatient setting. “Sometimes patients struggle with transportation, as two separate trips to the doctor and pharmacy may not be feasible. Additionally, these same patients may have limited access to health care and therefore may use an urgent care facility for their acute infection–like symptoms,” Dr. Bhakta explained.

Dr. Young, who is of Asian descent, first became interested in disparities in health care when he noticed that ethnic minority groups showed greater hesitancy toward COVID-19 vaccination. “I noticed that there weren’t many Asians involved in previous trials and realized at this point that disparities were rampant.”

Dr. Young had been involved in investigating the overall use and the inappropriate use of antibiotics across the whole U.S. population when his interest in health disparities prompted him to study these patterns in specific demographic groups.

“Most previous data are derived from inpatient studies where the physician is giving the antibiotics,” said Dr. Young, who looked specifically at outpatient prescribing.

Dr. Young used prescribing data from the Centers for Disease Control and Prevention’s National Ambulatory Medical Care Survey, which covers more than 5.7 billion adult (aged 18 and older) and 1.3 billion child visits to outpatient practices between 2009 and 2016 across all 50 U.S. states and Washington, D.C.

He gathered patient data on ICD-9-CM and ICD-10 diagnostic codes for infections and for diagnoses that “appeared like infections.” All of the patients who were included had received at least one oral antibiotic. Antibiotic prescribing was defined as visits that included an antibiotic per 1,000 total patient visits.

On the basis of previous research, Dr. Young and his colleagues then determined whether each antibiotic prescription was appropriate, possibly appropriate, or inappropriate. Patient demographics included age (younger than 18 years, 18-64 years, and older than 64 years), sex (male or female), race, and ethnicity (White, Black, more than one race, Hispanic/Latinx, and other). These data were used to evaluate overall and inappropriate use.

“The health care community needs to be really careful with the judicious use of antibiotics,” Dr. Young said. “We have good guidelines on antimicrobial stewardship both in the inpatient and outpatient settings, but sometimes we overlook the disparities and cultural implications held by some patients.”

Typical examples of socioeconomic and cultural factors at play included patients not being able to afford the antibiotics, having limited access to care, or not returning for a follow-up visit for whatever reason.

“Patients of Black and Hispanic descent often don’t have the same degree of established care that many White patients have,” Dr. Young noted.

In the future, Dr. Young wants to conduct research into whether patients are actually taking their prescribed antibiotics, as well as their outcomes. For example, he would like to investigate whether rates of antibiotic resistance or Clostridioides difficile infection are higher among Black patients.

Dr. Young and Dr. Bhakta have disclosed no relevant financial relationships.

In this column I have previously discussed the microbiome and its importance to health, especially as it relates to infections in children. Given the appreciated connection between microbiome and immunity, my group in Rochester, N.Y., recently undertook a study of the effect of antibiotic usage on the immune response to routine early childhood vaccines. In mouse models, it was previously shown that antibiotic exposure induced a reduction in the abundance and diversity of gut microbiota that in turn negatively affected the generation and maintenance of vaccine-induced immunity.^1,2 A study from Stanford University was the first experimental human trial of antibiotic effects on vaccine responses. Adult volunteers were given an antibiotic or not before seasonal influenza vaccination and the researchers identified specific bacteria in the gut that were reduced by the antibiotics given. Those normal bacteria in the gut microbiome were shown to provide positive immunity signals to the systemic immune system that potentiated vaccine responses.³

My group conducted the first-ever study in children to explore whether an association existed between antibiotic use and vaccine-induced antibody levels. In the May issue of Pediatrics we report results from 560 children studied.⁴ From these children, 11,888 serum antibody levels to vaccine antigens were measured. Vaccine-induced antibody levels were determined at various time points after primary vaccination at child age 2, 4, and 6 months and boosters at age 12-18 months for 10 antigens included in four vaccines: DTaP, Hib, IPV, and PCV. The antibody levels to vaccine components were measured to DTaP (diphtheria toxoid, pertussis toxoid, tetanus toxoid, pertactin, and filamentous hemagglutinin), Hib conjugate (polyribosylribitol phosphate), IPV (polio 2), and PCV (serotypes 6B, 14, and 23F). A total of 342 children with 1,678 antibiotic courses prescribed were compared with 218 children with no antibiotic exposures. The predominant antibiotics prescribed were amoxicillin, cefdinir, amoxicillin/clavulanate, and ceftriaxone, since most treatments were for acute otitis media.

Of possible high clinical relevance, we found that from 9 to 24 months of age, children with antibiotic exposure had a higher frequency of vaccine-induced antibody levels below protection compared with children with no antibiotic use, placing them at risk of contracting a vaccine-preventable infection for DTaP antigens DT, TT, and PT and for PCV serotype 14.

For time points where antibody levels were determined within 30 days of completion of a course of antibiotics (recent antibiotic use), individual antibiotics were analyzed for effect on antibody levels below protective levels. Across all vaccine antigens measured, we found that all antibiotics had a negative effect on antibody levels and percentage of children achieving the protective antibody level threshold. Amoxicillin use had a lower association with lower antibody levels than the broader spectrum antibiotics, amoxicillin clavulanate (Augmentin), cefdinir, and ceftriaxone. For children receiving amoxicillin/clavulanate prescriptions, it was possible to compare the effect of shorter versus longer courses and we found that a 5-day course was associated with subprotective antibody levels similar to 10 days of amoxicillin, whereas 10-day amoxicillin/clavulanate was associated with higher frequency of children having subprotective antibody levels (Figure).

We examined whether accumulation of antibiotic courses in the first year of life had an association with subsequent vaccine-induced antibody levels and found that each antibiotic prescription was associated with a reduction in the median antibody level. For DTaP, each prescription was associated with 5.8% drop in antibody level to the vaccine components. For Hib the drop was 6.8%, IPV was 11.3%, and PCV was 10.4% – all statistically significant. To determine if booster vaccination influenced this association, a second analysis was performed using antibiotic prescriptions up to 15 months of age. We found each antibiotic prescription was associated with a reduction in median vaccine-induced antibody levels for DTaP by 18%, Hib by 21%, IPV by 19%, and PCV by 12% – all statistically significant.

Our study is the first in young children during the early age window where vaccine-induced immunity is established. Antibiotic use was associated with increased frequency of subprotective antibody levels for several vaccines used in children up to 2 years of age. The lower antibody levels could leave children vulnerable to vaccine preventable diseases. Perhaps outbreaks of vaccine-preventable diseases, such as pertussis, may be a consequence of multiple courses of antibiotics suppressing vaccine-induced immunity.

A goal of this study was to explore potential acute and long-term effects of antibiotic exposure on vaccine-induced antibody levels. Accumulated antibiotic courses up to booster immunization was associated with decreased vaccine antibody levels both before and after booster, suggesting that booster immunization was not sufficient to change the negative association with antibiotic exposure. The results were similar for all vaccines tested, suggesting that the specific vaccine formulation was not a factor.

The study has several limitations. The antibiotic prescription data and measurements of vaccine-induced antibody levels were recorded and measured prospectively; however, our analysis was done retrospectively. The group of study children was derived from my private practice in Rochester, N.Y., and may not be broadly representative of all children. The number of vaccine antibody measurements was limited by serum availability at some sampling time points in some children; and sometimes, the serum samples were collected far apart, which weakened our ability to perform longitudinal analyses. We did not collect stool samples from the children so we could not directly study the effect of antibiotic courses on the gut microbiome.

Our study adds new reasons to be cautious about overprescribing antibiotics on an individual child basis because an adverse effect extends to reduction in vaccine responses. This should be explained to parents requesting unnecessary antibiotics for colds and coughs. When antibiotics are necessary, the judicious choice of a narrow-spectrum antibiotic or a shorter duration of a broader spectrum antibiotic may reduce adverse effects on vaccine-induced immunity.

Across all vaccine antigens measured, we found that all antibiotics had a negative effect on antibody levels and percentage of children achieving the protective antibody level threshold. Amoxicillin use had a lower association with lower antibody levels than the broader spectrum antibiotics, amoxicillin clavulanate (Augmentin), cefdinir, and ceftriaxone. For children receiving amoxicillin/clavulanate prescriptions, it was possible to compare the effect of shorter versus longer courses and we found that a 5-day course was associated with subprotective antibody levels similar to 10 days of amoxicillin, whereas 10-day amoxicillin/clavulanate was associated with higher frequency of children having subprotective antibody levels (Figure).

We examined whether accumulation of antibiotic courses in the first year of life had an association with subsequent vaccine-induced antibody levels and found that each antibiotic prescription was associated with a reduction in the median antibody level. For DTaP, each prescription was associated with 5.8% drop in antibody level to the vaccine components. For Hib the drop was 6.8%, IPV was 11.3%, and PCV was 10.4% – all statistically significant. To determine if booster vaccination influenced this association, a second analysis was performed using antibiotic prescriptions up to 15 months of age. We found each antibiotic prescription was associated with a reduction in median vaccine-induced antibody levels for DTaP by 18%, Hib by 21%, IPV by 19%, and PCV by 12% – all statistically significant.

Our study is the first in young children during the early age window where vaccine-induced immunity is established. Antibiotic use was associated with increased frequency of subprotective antibody levels for several vaccines used in children up to 2 years of age. The lower antibody levels could leave children vulnerable to vaccine preventable diseases. Perhaps outbreaks of vaccine-preventable diseases, such as pertussis, may be a consequence of multiple courses of antibiotics suppressing vaccine-induced immunity.

A goal of this study was to explore potential acute and long-term effects of antibiotic exposure on vaccine-induced antibody levels. Accumulated antibiotic courses up to booster immunization was associated with decreased vaccine antibody levels both before and after booster, suggesting that booster immunization was not sufficient to change the negative association with antibiotic exposure. The results were similar for all vaccines tested, suggesting that the specific vaccine formulation was not a factor.

The study has several limitations. The antibiotic prescription data and measurements of vaccine-induced antibody levels were recorded and measured prospectively; however, our analysis was done retrospectively. The group of study children was derived from my private practice in Rochester, N.Y., and may not be broadly representative of all children. The number of vaccine antibody measurements was limited by serum availability at some sampling time points in some children; and sometimes, the serum samples were collected far apart, which weakened our ability to perform longitudinal analyses. We did not collect stool samples from the children so we could not directly study the effect of antibiotic courses on the gut microbiome.

Our study adds new reasons to be cautious about overprescribing antibiotics on an individual child basis because an adverse effect extends to reduction in vaccine responses. This should be explained to parents requesting unnecessary antibiotics for colds and coughs. When antibiotics are necessary, the judicious choice of a narrow-spectrum antibiotic or a shorter duration of a broader spectrum antibiotic may reduce adverse effects on vaccine-induced immunity.
