RBX2660 shows promise in breaking the cycle of recurrent C. difficile
CHARLOTTE, N.C. –
Following a standard course of antibiotics, a one-time treatment with RBX2660 was successful for three quarters of participants at 8 weeks, according to a new study. It also prevented additional bouts, with 84% of these initial responders remaining free of C. difficile infection at 6 months.
The ongoing phase 3, open-label PUNCH CD3-OLS study expands on clinical trial experience by treating more “real-world” patients. People who might have been excluded from previous research because of comorbidities, such as irritable bowel syndrome, inflammatory bowel disease, and immunosuppression, were included.
The study also placed no limit on the number of previous rounds of C. difficile infections.
“Even when you expand the patient population to make it more generalizable, we’re still seeing both a high cure rate and a high success rate,” Sahil Khanna, MBBS, a gastroenterologist and hepatologist at the Mayo Clinic in Rochester, Minn., said in an interview.
“We also are not seeing any kind of safety signals that can be attributed to this particular product,” he said.
Dr. Khanna presented the findings during the annual meeting of the American College of Gastroenterology, which were also published simultaneously in the journal Drugs. The research by Dr. Khanna and associates received an ACG Outstanding Research Award in the colon category.
Study design and results
RBX2660 (Rebyota) is a microbiota-based live biotherapeutic in development from Ferring Pharmaceuticals. The treatment contains human stool collected from prescreened, qualified donors and is prepared according to good manufacturing standards.
After standard-of-care antibiotics and a 72-hour washout period, participants received a single 150-mL dose rectally by enema. RBX2660 is administered by a health care professional.
The median age of study participants was 63 years, with 45% aged 65 years or older, and 70% were women. Overall, 37% of participants had Crohn’s disease and 4% had ulcerative colitis.
At the time of screening, about half of participants had a history of one or two infections with C. difficile, and the remaining half reported three or more episodes.
Of the 402 participants whose outcomes could be analyzed, 75% reported treatment success, meaning no further C. difficile infections at 8 weeks. This was consistent with the 75% of 60 participants free of C. difficile in the interim analysis reported in 2021. Efficacy results were based on a modified intent-to-treat analysis.
Of the 300 participants who responded to RBX2660 at 8 weeks, 262 were followed up to 6 months, with 84% of these reporting no C. difficile recurrence.
“If you succeeded to 8 weeks, there was a high likelihood that you would succeed up to 6 months,” Dr. Khanna said.
For the subset of participants with inflammatory bowel disease, Dr. Khanna noted that the success rates were in the 80% range, which is higher than what is seen in clinic fecal microbiota transplantation programs.
Adverse events
Of the participants, 63% reported treatment-emergent adverse events. Most events were mild to moderate in severity, the researchers reported, with diarrhea and abdominal pain being the most common.
“When you look at the treatment-emergent adverse events, it’s important to put them into context in terms of this patient population,” Dr. Khanna said. “This recurrent population has developed underlying gastrointestinal symptoms like abdominal pain, diarrhea, nausea, vomiting, and weight loss.”
Some of these adverse events persist beyond resolution of the C. difficile infection, and the adverse-event profile with RBX2660 is consistent with what is seen following fecal microbiota transplantation, he added.
The serious adverse events “were very, very few,” Dr. Khanna said.
Overall, 11% of participants reported a serious adverse event. The majority were related to the C. difficile infection or an underlying comorbidity, he noted.
“Excruciating for patients to deal with”
Traditionally, there could be “some hesitation on the patient’s part [to undergo therapy] just because it’s delivered rectally,” session comoderator Lisa Malter, MD, said in an interview.
However, C. difficile can be “excruciating for patients to deal with,” said Dr. Malter, a gastroenterologist and professor of medicine at New York University Langone Health. They “may be more than willing to take [this agent] because it gets them feeling better.”
“This is a positive adjunct to our current therapies for C. diff in terms of trying to knock it out once a standard course of antibiotics has been administered,” she added.
Currently, people with recurrent C. difficile seek fecal microbiota material from a biobank or from a close friend or loved one.
But Dr. Malter noted that asking someone you know to donate fecal matter for transplantation requires several steps. Donors are screened to make sure they are free of gastrointestinal illness, are not taking any contraindicated medications, and do not have active infection.
Fecal microbiota samples from a biobank are more standardized, but there have been intermittent shutdowns and availability has been limited during the pandemic, she said.
Dr. Malter added that one unanswered question is how much of the colon is covered by therapy delivery via enema compared with colonoscope delivery during fecal microbiota transplantation.
“If it’s delivered colonoscopically, you get the entire colon. In contrast with an enema, you really only hit the left side of the colon,” she said.
FDA advisory committee nod
On Sept. 26, the Food and Drug Administration’s Vaccines and Related Biological Products Advisory Committee reviewed evidence for RBX2660. The committee voted 13 to 4 that data were adequate to support the effectiveness of RBX2660 to reduce the recurrence of C. difficile infection in adults following antibiotic treatment for recurrent infections.
Members also voted 12 to 4, with one abstention, that the data were adequate to support the product’s safety.
The FDA often follows its advisory committee recommendations but is not required to do so.
“The hope would be that this would get through the usual FDA pipeline of an approval in the near future,” Dr. Khanna said.
The study was funded by Ferring Pharmaceuticals. Dr. Khanna reported receiving grant and research funding from Ferring. Dr. Malter reported no relevant financial relationships.

Droplet dispersal in sterile processing units far exceeds guideline limit
In the era of Ebola, COVID-19, and even Legionnaires, technicians and other staff working behind the scenes to ensure provider and patient safety continue to face a long-recognized but under addressed challenge: splashes and airborne droplets.
Granted, National Institute for Occupational Safety and Health (NIOSH) standards, industry standards, and professional guidelines are all in place to prevent unintentional exposure to pathogens. However, findings from a newly published study in the American Journal of Infection Control suggest they fall short.
In the study, researchers found that simulated manual cleaning of medical devices generated a drenching splash throughout the process with droplet dispersal exceeding 7 feet (2.1 meters).
Cori L. Ofstead, MSPH, lead author and president/CEO of Ofstead & Associates, Bloomington, Minn., told this news organization. “That’s the problem with having standards and guidelines that are not based on relevant evidence, [which] in this case, is a single study that was done in an intensive care area where they had an infection outbreak.”
Ms. Ofstead was referring to a report in the journal Infection Control and Hospital Epidemiology, detailing a Canadian investigation involving a multidrug-resistant Pseudomonas aeruginosa outbreak in an ICU. The report implicated the faucets over the hand hygiene sinks, with fluorescent dye showing droplet dispersal roughly 3 feet away from the sinks.
“Somehow it [the 3-feet rule] got implemented in guidelines in sterile processing decontamination areas, which are not the same as hand hygiene,’’ Ms. Ofstead explained.
With a goal of providing more current evidence on droplet generation and dispersal, as well as personal protection equipment (PPE) exposure/effectiveness, she and her colleagues simulated manual cleaning of a decommissioned colonoscope and transvaginal ultrasound probe, using for the study location a new academic sterile processing unit.
To detect droplet generation and dispersal as well as splash following common technician activities (for example, colonoscope brushing, scrubbing, rinsing and transport to an automated endoscope reprocessor [AER] for sterilization), the researchers affixed blue moisture-detection paper to environmental surfaces, on carts positioned 4 feet (1.2 meters) from the sink (to simulate observers), and along a 15-foot pathway between the sink and AER.
They observed droplets everywhere.
Technician activities such as running the faucet and rinsing the probe under running water generated substantial splashing overall. Instrument rinsing in particular produced small and large droplets and confluent puddles of water around the sink and in the broad area surrounding the workspace. Droplets were also dispersed on the floor 7.25 feet (2.2 meters) away and along the entire 15-foot path from the sink to the AER.
At the sink, the technician risked drenching exposure from head to toe during most activities, and even observers positioned 3-4 feet away were found to have droplets on their gowns. In addition, saturated shoe covers reportedly tracked moisture away from the sink to the unit door – a distance of 13 feet (4 meters) – and 2 feet (0.6 meters) farther out into the PPE foyer for donning and doffing.
Although PPE gowns effectively repelled moisture during cleaning of a single device, Ms. Ofstead emphasized that technicians typically handle up to 10 instruments during a normal, 2-hour shift, further increasing exposure risk with each subsequent cleaning.
However, perhaps one of the most surprising findings was that despite an optimal unit design, including physical separation of clean and dirty activities and pressurized air flow to protect workers, droplets were still broadly dispersed.
Current efforts, however well-intentioned, might not be offering the degree of protection (and consideration) that sterile processing technicians need.
“The study was conducted in a new sterile processing area that had an extra excellent kind of distancing and three separate rooms, something that I think most of our hospitals are working toward,” Stella Hines, MD, associate professor at the University of Maryland School of Medicine, Baltimore, explained. Dr. Hines was not directly involved in the study.
“But it also really kind of highlighted what’s happening to workers potentially,” she added. “For example, we want to know if that spray or splatter has a live microbe it in that could cause a problem or ... in a highly wet environment, if that water has some kind of chemical in it that could pose an occupational hazard to the worker based on skin or mucous membrane exposure.”
Ms. Ofstead agreed. “We need to be thinking about the exposure of critically important workers and the environment in an era where we are worried about aerosol-generating procedures and superbugs,” she explained.
Dr. Hines and Ms. Ofstead also noted that the majority of staff involved in front-line patient care have never actually ventured into the sterile processing units nor do they recognize the risks that technicians working in these units face on a daily, or even hourly, basis.
“The people who run these operations are very well trained and knowledgeable. I think that it would be helpful for them to know that they’re appreciated and for the people upstairs on the front lines using the equipment to see what goes on downstairs and all of the painstaking steps that need to be in place for the equipment to come out of sterile processing and be ready to go,” said Dr. Hines.
In the meantime, hospital leaders need to address the challenges and danger posed by migrating infectious droplets, especially for workers involved in processes that stir them up in the first place – workers who by the end of their shifts are unavoidably drenched with infectious blood and tissue secretions.
“I think that it’s going to take a much bigger kind of worldview from hospital leadership,” Dr. Hines said.
The study was supported in part by a grant from Healthmark Industries. Ms. Ofstead reports research grants or consulting fees through her organization with 3M Company, Ambu, Boston Scientific, Cleanis, Fortive/Advanced Sterilization Products, Healthmark Industries, Pentax, and Steris/Cantel/Medviators. Dr. Hines reports no relevant financial relationships.

“I think that it’s going to take a much bigger kind of worldview from hospital leadership,” Dr. Hines said.
The study was supported in part by a grant from Healthmark Industries. Ms. Ofstead reports research grants or consulting fees through her organization with 3M Company, Ambu, Boston Scientific, Cleanis, Fortive/Advanced Sterilization Products, Healthmark Industries, Pentax, and Steris/Cantel/Medviators. Dr. Hines reports no relevant financial relationships.

Is it flu, RSV, or COVID? Experts fear the ‘tripledemic’
Just when we thought this holiday season, finally, would be the back-to-normal one, some infectious disease experts are warning that a so-called “tripledemic” – influenza, COVID-19, and RSV – may be in the forecast.
The warning isn’t without basis.
The flu season has gotten an early start. As of Oct. 21, early increases in seasonal flu activity have been reported in most of the country, the Centers for Disease Control and Prevention said, with the southeast and south-central areas having the highest activity levels.
Children’s hospitals and EDs are seeing a surge in children with RSV.
COVID-19 cases are trending down, according to the CDC, but epidemiologists – scientists who study disease outbreaks – always have their eyes on emerging variants.
said Justin Lessler, PhD, a professor of epidemiology at the University of North Carolina at Chapel Hill. Dr. Lessler is on the coordinating team for the COVID-19 Scenario Modeling Hub, which aims to predict the course COVID-19, and the Flu Scenario Modeling Hub, which does the same for influenza.
For COVID-19, some models are predicting some spikes before Christmas, he said, and others see a new wave in 2023. For the flu, the model is predicting an earlier-than-usual start, as the CDC has reported.
While flu activity is relatively low, the CDC said, the season is off to an early start. For the week ending Oct. 21, 1,674 patients were hospitalized for flu, higher than in the summer months but fewer than the 2,675 hospitalizations for the week of May 15, 2022.
As of Oct. 20, COVID-19 cases have declined 12% over the last 2 weeks, nationwide. But hospitalizations are up 10% in much of the Northeast, The New York Times reports, and the improvement in cases and deaths has been slowing down.
As of Oct. 15, 15% of RSV tests reported nationwide were positive, compared with about 11% at that time in 2021, the CDC said. The surveillance collects information from 75 counties in 12 states.
Experts point out that the viruses – all three are respiratory viruses – are simply playing catchup.
“They spread the same way and along with lots of other viruses, and you tend to see an increase in them during the cold months,” said Timothy Brewer, MD, professor of medicine and epidemiology at UCLA.
The increase in all three viruses “is almost predictable at this point in the pandemic,” said Dean Blumberg, MD, a professor and chief of pediatric infectious diseases at the University of California Davis Health. “All the respiratory viruses are out of whack.”
Last year, RSV cases were up, too, and began to appear very early, he said, in the summer instead of in the cooler months. Flu also appeared early in 2021, as it has in 2022.
That contrasts with the flu season of 2020-2021, when COVID precautions were nearly universal, and cases were down. At UC Davis, “we didn’t have one pediatric admission due to influenza in the 2020-2021 [flu] season,” Dr. Blumberg said.
The number of pediatric flu deaths usually range from 37 to 199 per year, according to CDC records. But in the 2020-2021 season, the CDC recorded one pediatric flu death in the U.S.
Both children and adults have had less contact with others the past two seasons, Dr. Blumberg said, “and they don’t get the immunity they got with those infections [previously]. That’s why we are seeing out-of-season, early season [viruses].”
Eventually, he said, the cases of flu and RSV will return to previous levels. “It could be as soon as next year,” Dr. Blumberg said. And COVID-19, hopefully, will become like influenza, he said.
“RSV has always come around in the fall and winter,” said Elizabeth Murray, DO, a pediatric emergency medicine doctor at the University of Rochester (N.Y.) Medical Center and a spokesperson for the American Academy of Pediatrics. In 2022, children are back in school and for the most part not masking. “It’s a perfect storm for all the germs to spread now. They’ve just been waiting for their opportunity to come back.”
Self-care vs. not
RSV can pose a risk for anyone, but most at risk are children under age 5, especially infants under age 1, and adults over age 65. There is no vaccine for it. Symptoms include a runny nose, decreased appetite, coughing, sneezing, fever, and wheezing. But in young infants, there may only be decreased activity, crankiness, and breathing issues, the CDC said.
Keep an eye on the breathing if RSV is suspected, Dr. Murray tells parents. If your child can’t breathe easily, is unable to lie down comfortably, can’t speak clearly, or is sucking in the chest muscles to breathe, get medical help. Most kids with RSV can stay home and recover, she said, but often will need to be checked by a medical professional.
She advises against getting an oximeter to measure oxygen levels for home use. “They are often not accurate,” she said. If in doubt about how serious your child’s symptoms are, “don’t wait it out,” and don’t hesitate to call 911.
Symptoms of flu, COVID, and RSV can overlap. But each can involve breathing problems, which can be an emergency.
“It’s important to seek medical attention for any concerning symptoms, but especially severe shortness of breath or difficulty breathing, as these could signal the need for supplemental oxygen or other emergency interventions,” said Mandy De Vries, a respiratory therapist and director of education at the American Association for Respiratory Care. Inhalation treatment or mechanical ventilation may be needed for severe respiratory issues.
Precautions
To avoid the tripledemic – or any single infection – Timothy Brewer, MD, a professor of medicine and epidemiology at the University of California, Los Angeles, suggests some familiar measures: “Stay home if you’re feeling sick. Make sure you are up to date on your vaccinations. Wear a mask indoors.”

HPV-positive women who undergo IVF don’t have worse outcomes
A new study provides more evidence that HPV infection doesn’t raise the risk of poor outcomes in women who undergo fertility treatment via in vitro fertilization with fresh embryos. In fact, HPV-positive women were somewhat more likely than HPV-negative women to become pregnant (relative risk, 1.20; 95% confidence interval, 1.03-1.39) and have live births (RR, 1.39; 95% CI, 1.13-1.70), researchers reported Oct. 24 at the American Society for Reproductive Medicine’s 2022 meeting .
“This evidence should reassure women that being HPV positive will not affect live birth rates after a fresh embryo transfer cycle,” said study coauthor and ob.gyn. Nina Vyas, MD, a clinical fellow at Weill Cornell Medicine, New York, in an interview.
According to Dr. Vyas, previous studies have offered conflicting results about whether HPV affects pregnancy outcomes. In 2006, for example, her group performed a pilot study (Fertil Steril. Jun 16. doi: 10.1016/j.fertnstert.2006.01.051) that linked lower pregnancy rates to HPV-positive tests on the day of egg retrieval.
“We sought to reevaluate this finding in a retrospective manner,” Dr. Vyas said. “You’re taking eggs out of their home, injecting with sperm, and putting them back. There’s so much that we don’t know, and we want to make sure there’s no extra risk.”
Also, she added, “prior studies had a relatively low sample size. We sought to use our patient volume to address this question on a larger scale. Our current study benefits from a large sample size and using the clinically meaningful endpoint of live birth as our primary outcome.”
For the new study, researchers retrospectively analyzed 1,333 patients (of 2,209 screened) who received first fresh embryo transfers from 2017 to 2019. All had cytology or HPV status documented per cervical cancer screening guidelines within 6 months before embryos were transferred.
The researchers looked at only fresh embryo transfers “so we could account for pregnancy outcomes closest to the documented HPV status at the time of egg retrieval,” Dr. Vyas said.
Ten percent (133) of patients were HPV positive. Of those, 60.1% became pregnant, and 43.6% of them had live births. Of the HPV-negative women (90% of subjects, n = 1,200), 52.2% became pregnant and 33.5% had live births. The researchers didn’t calculate P values, but Dr. Vyas said an analysis determined that the differences between HPV-positive and HPV-negative women were statistically significant.
The study size doesn’t allow researchers to determine whether HPV actually has a protective effect on pregnancy/live birth rates in IVF, Dr. Vyas said. Even if it did, the virus is dangerous.
What else could explain the discrepancy? “Some elements driving this could the smaller sample size of the HPV-positive group, differences in HPV prevalence between the general population and our population,” she said, “or other confounding factors we were not able to appreciate due to the limitations of the retrospective study.”
Researchers also reported that they found “no significant difference in biochemical or spontaneous abortion rates” between HPV-positive and HPV-negative women.
What is the message of the study? “Women with HPV can rest assured that they won’t have worse outcomes than their non-HPV [infected] counterparts after a fresh embryo transfer cycle,” Dr. Vyas said.
In an interview, McGill University, Montreal, epidemiologist Helen Trottier, PhD, MSc, noted that she recently coauthored a study that linked persistent HPV infection in pregnancy to premature births. The findings appear convincing, she said: “I think we can say that HPV is associated with preterm birth.”
She praised the new study but noted “the relative risks that are reported need to be adjusted for race and possibly other factors.”
Dr. Vyas said that kind of adjustment will occur in a future study that’s in progress. “We are now prospectively enrolling patients and collecting cytology data to understand whether there might be a difference for women with higher malignancy potential/different types of HPV genotypes.”
The study authors have no disclosures. Disclosure information for Dr. Trottier was unavailable.

IgA Vasculitis in the Setting of Biologic Therapy for Psoriasis and Recurrent Cutaneous Methicillin-Resistant Staphylococcus aureus Colonization
Case Report
A 47-year-old man presented with a sudden-onset rash consisting of red bumps on the abdomen and legs that had been ongoing for several days. He had known psoriasis and psoriatic arthritis that had been well controlled with adalimumab for the last 18 months. He reported concurrent onset of nausea but denied fevers, chills, night sweats, unintentional weight loss, abdominal pain, and pruritus. He endorsed prior cutaneous infections of methicillin-resistant Staphylococcus aureus (MRSA). His medical history also included diabetes mellitus, hypertension, and obesity. His other medications included oral losartan-hydrochlorothiazide, amlodipine, naproxen, and atorvastatin.
Physical examination revealed numerous thin purpuric papules—some with adherent scale—distributed on the lower legs, extensor forearms, and abdomen. Abdominal lesions were confined to weight-related striae (Figure 1). The palms, soles, oral mucosa, and face were spared. Three punch biopsies were performed, including 1 for direct immunofluorescence (DIF), and the patient was instructed to apply clobetasol to the affected areas twice daily until further notice.
Pathology showed perivascular extravasation of erythrocytes, neutrophils, eosinophils, and leukocytoclasis surrounding blood vessels associated with fibrin (Figure 2). Direct immunofluorescence showed granular deposition of IgA, complement component 3, and fibrinogen in a superficial dermal vascular pattern (Figure 3). These results were consistent with IgA small-vessel vasculitis. One specimen was consistent with the patient’s known psoriasis.
Urinalysis revealed moderate hemoglobinuria, and urine microscopy showed 174 red blood cells per high-power field. Creatinine was high at 1.87 mg/dL (reference range, <1.34 mg/dL; patient’s baseline, 0.81 mg/dL) and glomerular filtration rate was low (42 mL/min, patient’s baseline, >60 mL/min [reference range, 90–120 mL/min]). Erythrocyte sedimentation rate (21 mm/h [reference range, 0–22 mm/h]) and C-reactive protein were elevated (2.2 mg/dL [reference range, 0.3–1.0 mg/dL]). Given his history of cutaneous MRSA infections, a bacterial culture swab was collected from the skin surface to check for colonization, which showed moderate growth of MRSA. Naproxen was discontinued over concern of worsening the patient’s renal status. The patient was instructed to rest at home with his legs elevated, wear compression socks when ambulatory, use chlorhexidine antiseptic daily as a body wash when showering, and apply mupirocin three times daily to the biopsy sites. He was referred to urology for his microhematuria, where cystoscopy revealed no abnormalities.A month passed with no improvement of the patient’s cutaneous vasculitis, and his psoriatic arthritis worsened without his usual use of naproxen. He developed abdominal pain and loss of appetite. A prednisone taper was ordered starting at 40 mg/d (28.8 mg/kg), which provided relief of the skin and joint symptoms only until the course was completed 12 days later.
Five weeks after the initial presentation, the patient returned with a more severe eruption consisting of innumerable purpuric papules that coalesced in plaques on the abdomen, arms, and legs. He also had erythematous facial pustules and mild palmar petechiae (Figure 4). Three biopsies were performed, including 1 for DIF and 1 from a pustule on the forehead. Histology and DIF were again consistent with IgA small-vessel vasculitis. The forehead biopsy was compatible with steroid acne (attributed to recent prednisone use) and psoriasis.
Rheumatology was consulted, and adalimumab was discontinued 6 weeks after the initial presentation out of concern for drug-induced cutaneous vasculitis. Vasculitis work-up was unremarkable, including antineutrophil cytoplasmic antibodies, rheumatoid factor, cyclic citrullinated peptide, and serum protein electrophoresis. Oral dapsone was started at 100 mg/d, with the tentative plan of starting secukinumab if cutaneous symptoms improved. For 3 weeks, the patient’s cutaneous symptoms steadily improved.
Nine weeks after initial presentation to dermatology (3 weeks after discontinuing adalimumab) the patient self-administered his first dose of secukinumab at home. Several hours later, he reported sudden reappearance of vasculitis. He denied diarrhea, abdominal pain, bowel movement urgency, fevers, fatigue, and unintentional weight loss. Antistreptolysin O and hepatitis A antibodies were negative. He was instructed to hold secukinumab indefinitely.
Four weeks after his only secukinumab injection, the patient reported another episode of acute worsening cutaneous symptoms. A 4-week prednisone taper starting at 40 mg/d was ordered. Computed tomography of the chest, abdomen, and pelvis to rule out internal malignancy was unremarkable. Around this time, the patient reported major emotional distress related to an unexpected death in his family, which added to a gradual increase in his stress level related to the COVID-19 pandemic.
Three weeks later, dapsone was increased to 100 mg twice daily on account of the patient’s adiposity and lack of cutaneous improvement on the lower dose. Subsequently, the vasculitis rapidly improved for 2 weeks. The patient then reported symptoms of headache, dizziness, and chills. He was tested for COVID-19 and was negative. Six weeks after increasing the dapsone dose (5 months after initial presentation), the skin was normalizing, showing only faintly hyperpigmented macules confined to areas of resolved vasculitis (forearms, abdomen, legs).
The patient had been on dapsone 100 mg twice daily for 3 months when he was started on ustekinumab (90 mg at weeks 0 and 4, with planned doses every 12 weeks) for psoriatic arthritis in hopes of withdrawing dapsone. His cutaneous symptoms have remained well controlled on this regimen for 18 months. Lowering of dapsone below 100 mg daily has resulted in recurrent mild vasculitis symptoms; he now maintains the once-daily dosing without negative side effects.
Comment
IgA vasculitis is a form of cutaneous small-vessel leukocytoclastic vasculitis (LCV) characterized by episodes of palpable purpura on the extensor surfaces of the arms and legs that may be associated with arthritis, abdominal pain, and/or hematuria. Although vasculitis is a known potential adverse effect of anti–tumor necrosis factor (TNF) α therapy, cases of adalimumab-induced IgA vasculitis are uncommon. As use of more targeted therapies for psoriasis and psoriatic arthritis, such as the IL-17 inhibitor secukinumab, increases so do reports of associated adverse events. Of 6 previously reported cases of secukinumab-associated vasculitis, at least 4 were IgA vasculitis (Table).1-6 Another case described one patient with rheumatoid arthritis undergoing secukinumab treatment who experienced necrotizing glomerulonephritis; however, the authors concluded secukinumab likely was not causative in that case, as serologies and urinalyses suggested gradual onset of the process prior to initiating the medication.7
The exact pathogenesis of IgA vasculitis is unclear, but a prevailing theory involves the dysregulation of IgA synthesis and metabolism. Other than increased serum levels of transforming growth factor β, which is a major stimulating factor for IgA production, it also has been hypothesized that the presence of aberrantly hypoglycosylated IgA exposes an autoepitope for recognition by other pathogenic IgG and IgA, leading to the formation of large immune complexes that can readily deposit in postcapillary venules. The deposition of IgA immune complexes in postcapillary venules and the subsequent activation of the complement system causes direct damage to the endothelial cells of vessel walls. This complement activation is evidenced by vascular complement component 3 deposition on DIF (a nonspecific feature of LCV). Chemotaxis of neutrophils ensues, followed by their firm adherence and transendothelial migration (mediated by monocyte chemoattractant protein 1 [MCP-1]). Neutrophil degranulation releases reactive oxygen species and cytokines, which in turn recruit additional leukocytes to the area of inflammation, subsequently undergoing degeneration (leukocytoclasis). Microvascular permeability also is enhanced by MCP-1, allowing exudation of serum, erythrocytes, and fibrin. In the setting of elevated circulating TNF and IL-1, endothelium is stimulated to activate the intrinsic and extrinsic coagulation pathways. This decreases endothelial fibrinolytic activity, leading to thrombosis. The high venous pressure and low fibrinolytic activity in the lower legs explains why vasculitic lesions often are confined to or begin in this distribution.1,8-10
There also are noteworthy roles for cytokines in LCV. Circulating transforming growth factor β and IL-6—which are necessary for development of T helper 17 (TH17) cells and production of IL-17—are higher in patients with LCV compared to controls. Peripheral blood monocytes in patients with LCV demonstrate higher production of IL-17. Once TH17 cells develop, their survival and phenotype are maintained by IL-23 (considered the master regulator of TH17 differentiation). IL-17 is a potent chemoattractant of IL-8 (CXCL8) and MCP-1, both of which promote neutrophil-mediated perivascular inflammation. The IL-23 and IL-17 pathways implicated in the pathogenesis of psoriasis also cause neutrophil activation and upregulate transcription of proinflammatory cytokines (IL-1, IL-6, IL-8, and TNF-α), which overlap with those implicated in LCV. Autoimmune disease generally entails some positive feedback loop of progressively severe self-recognition and tissue destruction by the immune system. These shared cytokinetic processes may explain how the internal environment of psoriasis could perpetuate IgA vasculitis.1,2,8,10-12
The mechanisms underlying vasculitis associated with adalimumab are unclear, but hypotheses involve direct toxicity on vessels, capillary deposition of anti-TNF/TNF immune complexes, or an inflammatory process resulting in autoantibodies. Similar hypotheses are posited for secukinumab-associated vasculitis, including deposition of secukinumab–IL-17 complexes. Anti–TNF-α medications may increase TH17 cell numbers, leading to increased production of IL-22 and a resultant immunologic microenvironment conducive to vasculitis. All 6 published cases of secukinumab-associated vasculitis that we found had received prior treatment with a TNF-α blocker, but only 1 had occurrence of vasculitis during that treatment.1-6,10
In the 6 cases we reviewed, the time from starting secukinumab to onset of vasculitis ranged from 1 to 18 months. Our patient’s same-day re-emergence of vasculitis after his first secukinumab dose was so acute that we were skeptical of secukinumab as a potential trigger; this may simply have been coincident to the natural waxing and waning of the vasculitis (although onset of IgA vasculitis within 1 day of starting anti–TNF-α therapy has been reported).1-6,13
Specific associations of IgA vasculitis are many and can include bacterial organisms such as Helicobacter pylori, streptococci, and staphylococci. Although internal mucous membrane infections are considered more linked because of the surveillance role of IgA predominantly in mucosal tissues, it is possible that our patient with cutaneous MRSA harbored the same within the nasal mucosa. Our patient also received multiple vaccinations outside our department throughout his clinical course (2 hepatitis B and 1 pneumococcal conjugate), which are known potential triggers for vasculitis. Psychological stress is a known trigger for psoriasis, and given the cytokinetic relationship of psoriasis to vasculitis described previously, it may have indirectly contributed to vasculitis in our case. The anxiety associated with being immunosuppressed during the COVID-19 pandemic and bereavement of losing a family member may have contributed to the refractory nature of our patient’s condition. Renal involvement is relatively common in adults with IgA vasculitis and so should be ruled out, as should occult internal malignancy.8,10,14
It is unclear which of the above factors was causative in our case, but a multifactorial process is likely. Treatment of monoclonal antibody–associated vasculitis entails investigating for triggers and systemic involvement, removing the most likely culprit, quelling the vasculitis acutely, avoiding known potential exacerbators, and introducing an alternative long-term immunomodulant. In all 6 reported similar cases, discontinuation of secukinumab and initiation of prednisone or colchicine led to resolution.1-6 Dapsone also is acceptable for acute control of IgA vasculitis, although this medication is highly lipid soluble and penetrates well into various tissues.15 Thus, lower doses may prove ineffective for obese patients, as was demonstrated in our case. Given the known potential of vaccinations, infections, and other factors (eg, alcohol, penicillin) to trigger IgA vasculitis, these should be avoided.10
Blockade of IL-23 with ustekinumab has been suggested by other authors encountering secukinumab-associated vasculitis, as IL-23 is the main driver and sustainer of TH17 cell differentiation.8 Although 6 previously reported cases of secukinumab-associated vasculitis achieved resolution without long-term recurrence, none did so using an IL-23 inhibitor (nor had any of the described patients received IL-23 inhibitors previously).1-6 Given the established safety of IL-23 inhibitors and that they theoretically are well suited for this unique circumstance (by ceasing the main causative cytokine cascades “upstream”) and were efficacious in quickly resolving our patient’s vasculitis, we suggest that ustekinumab may represent

Case Report
A 47-year-old man presented with a sudden-onset rash consisting of red bumps on the abdomen and legs that had been ongoing for several days. He had known psoriasis and psoriatic arthritis that had been well controlled with adalimumab for the last 18 months. He reported concurrent onset of nausea but denied fevers, chills, night sweats, unintentional weight loss, abdominal pain, and pruritus. He endorsed prior cutaneous infections of methicillin-resistant Staphylococcus aureus (MRSA). His medical history also included diabetes mellitus, hypertension, and obesity. His other medications included oral losartan-hydrochlorothiazide, amlodipine, naproxen, and atorvastatin.
Physical examination revealed numerous thin purpuric papules—some with adherent scale—distributed on the lower legs, extensor forearms, and abdomen. Abdominal lesions were confined to weight-related striae (Figure 1). The palms, soles, oral mucosa, and face were spared. Three punch biopsies were performed, including 1 for direct immunofluorescence (DIF), and the patient was instructed to apply clobetasol to the affected areas twice daily until further notice.
Pathology showed perivascular extravasation of erythrocytes, neutrophils, eosinophils, and leukocytoclasis surrounding blood vessels associated with fibrin (Figure 2). Direct immunofluorescence showed granular deposition of IgA, complement component 3, and fibrinogen in a superficial dermal vascular pattern (Figure 3). These results were consistent with IgA small-vessel vasculitis. One specimen was consistent with the patient’s known psoriasis.
Urinalysis revealed moderate hemoglobinuria, and urine microscopy showed 174 red blood cells per high-power field. Creatinine was high at 1.87 mg/dL (reference range, <1.34 mg/dL; patient’s baseline, 0.81 mg/dL) and glomerular filtration rate was low (42 mL/min, patient’s baseline, >60 mL/min [reference range, 90–120 mL/min]). Erythrocyte sedimentation rate (21 mm/h [reference range, 0–22 mm/h]) and C-reactive protein were elevated (2.2 mg/dL [reference range, 0.3–1.0 mg/dL]). Given his history of cutaneous MRSA infections, a bacterial culture swab was collected from the skin surface to check for colonization, which showed moderate growth of MRSA. Naproxen was discontinued over concern of worsening the patient’s renal status.

Other than increased serum levels of transforming growth factor β, which is a major stimulating factor for IgA production, it also has been hypothesized that the presence of aberrantly hypoglycosylated IgA exposes an autoepitope for recognition by other pathogenic IgG and IgA, leading to the formation of large immune complexes that can readily deposit in postcapillary venules. The deposition of IgA immune complexes in postcapillary venules and the subsequent activation of the complement system causes direct damage to the endothelial cells of vessel walls. This complement activation is evidenced by vascular complement component 3 deposition on DIF (a nonspecific feature of LCV). Chemotaxis of neutrophils ensues, followed by their firm adherence and transendothelial migration (mediated by monocyte chemoattractant protein 1 [MCP-1]). Neutrophil degranulation releases reactive oxygen species and cytokines, which in turn recruit additional leukocytes to the area of inflammation, subsequently undergoing degeneration (leukocytoclasis). Microvascular permeability also is enhanced by MCP-1, allowing exudation of serum, erythrocytes, and fibrin. In the setting of elevated circulating TNF and IL-1, endothelium is stimulated to activate the intrinsic and extrinsic coagulation pathways. This decreases endothelial fibrinolytic activity, leading to thrombosis. The high venous pressure and low fibrinolytic activity in the lower legs explains why vasculitic lesions often are confined to or begin in this distribution.1,8-10
There also are noteworthy roles for cytokines in LCV. Circulating transforming growth factor β and IL-6—which are necessary for development of T helper 17 (TH17) cells and production of IL-17—are higher in patients with LCV compared to controls. Peripheral blood monocytes in patients with LCV demonstrate higher production of IL-17. Once TH17 cells develop, their survival and phenotype are maintained by IL-23 (considered the master regulator of TH17 differentiation). IL-17 is a potent chemoattractant of IL-8 (CXCL8) and MCP-1, both of which promote neutrophil-mediated perivascular inflammation. The IL-23 and IL-17 pathways implicated in the pathogenesis of psoriasis also cause neutrophil activation and upregulate transcription of proinflammatory cytokines (IL-1, IL-6, IL-8, and TNF-α), which overlap with those implicated in LCV. Autoimmune disease generally entails some positive feedback loop of progressively severe self-recognition and tissue destruction by the immune system. These shared cytokinetic processes may explain how the internal environment of psoriasis could perpetuate IgA vasculitis.1,2,8,10-12
The mechanisms underlying vasculitis associated with adalimumab are unclear, but hypotheses involve direct toxicity on vessels, capillary deposition of anti-TNF/TNF immune complexes, or an inflammatory process resulting in autoantibodies. Similar hypotheses are posited for secukinumab-associated vasculitis, including deposition of secukinumab–IL-17 complexes. Anti–TNF-α medications may increase TH17 cell numbers, leading to increased production of IL-22 and a resultant immunologic microenvironment conducive to vasculitis. All 6 published cases of secukinumab-associated vasculitis that we found had received prior treatment with a TNF-α blocker, but only 1 had occurrence of vasculitis during that treatment.1-6,10
In the 6 cases we reviewed, the time from starting secukinumab to onset of vasculitis ranged from 1 to 18 months. Our patient’s same-day re-emergence of vasculitis after his first secukinumab dose was so acute that we were skeptical of secukinumab as a potential trigger; this may simply have been coincident to the natural waxing and waning of the vasculitis (although onset of IgA vasculitis within 1 day of starting anti–TNF-α therapy has been reported).1-6,13
Specific associations of IgA vasculitis are many and can include bacterial organisms such as Helicobacter pylori, streptococci, and staphylococci. Although internal mucous membrane infections are considered more linked because of the surveillance role of IgA predominantly in mucosal tissues, it is possible that our patient with cutaneous MRSA harbored the same within the nasal mucosa. Our patient also received multiple vaccinations outside our department throughout his clinical course (2 hepatitis B and 1 pneumococcal conjugate), which are known potential triggers for vasculitis. Psychological stress is a known trigger for psoriasis, and given the cytokinetic relationship of psoriasis to vasculitis described previously, it may have indirectly contributed to vasculitis in our case. The anxiety associated with being immunosuppressed during the COVID-19 pandemic and bereavement of losing a family member may have contributed to the refractory nature of our patient’s condition. Renal involvement is relatively common in adults with IgA vasculitis and so should be ruled out, as should occult internal malignancy.8,10,14
It is unclear which of the above factors was causative in our case, but a multifactorial process is likely. Treatment of monoclonal antibody–associated vasculitis entails investigating for triggers and systemic involvement, removing the most likely culprit, quelling the vasculitis acutely, avoiding known potential exacerbators, and introducing an alternative long-term immunomodulant. In all 6 reported similar cases, discontinuation of secukinumab and initiation of prednisone or colchicine led to resolution.1-6 Dapsone also is acceptable for acute control of IgA vasculitis, although this medication is highly lipid soluble and penetrates well into various tissues.15 Thus, lower doses may prove ineffective for obese patients, as was demonstrated in our case. Given the known potential of vaccinations, infections, and other factors (eg, alcohol, penicillin) to trigger IgA vasculitis, these should be avoided.10
Blockade of IL-23 with ustekinumab has been suggested by other authors encountering secukinumab-associated vasculitis, as IL-23 is the main driver and sustainer of TH17 cell differentiation.8 Although 6 previously reported cases of secukinumab-associated vasculitis achieved resolution without long-term recurrence, none did so using an IL-23 inhibitor (nor had any of the described patients received IL-23 inhibitors previously).1-6 Given the established safety of IL-23 inhibitors and that they theoretically are well suited for this unique circumstance (by ceasing the main causative cytokine cascades “upstream”) and were efficacious in quickly resolving our patient’s vasculitis, we suggest that ustekinumab may represent

Practice Points
- Biologic medications including adalimumab and more rarely secukinumab may be associated with leukocytoclastic vasculitis; a smaller subset of patients may experience IgA vasculitis.
- The IL-23 blocker ustekinumab may represent an ideal therapeutic agent when secukinumabassociated vasculitis is suspected. Because IL-23 is the main driver and sustainer of TH17 cell differentiation, it may cease the main causative cytokine cascades “upstream.”
Side effects from COVID vaccine show its effectiveness
It means your body had a greater antibody response than people who had just a little pain or rash at the injection site, or no reaction at all.
That’s according to new research published in the journal JAMA Network Open .
“These findings support reframing postvaccination symptoms as signals of vaccine effectiveness and reinforce guidelines for vaccine boosters in older adults,” researchers from Columbia University in New York, the University of Vermont, and Boston University wrote.
The vaccines provided strong protection regardless of the level of reaction, researchers said. Almost all the study’s 928 adult participants had a positive antibody response after receiving two doses of vaccine.
“I don’t want a patient to tell me that, ‘Golly, I didn’t get any reaction, my arm wasn’t sore, I didn’t have fever. The vaccine didn’t work.’ I don’t want that conclusion to be out there,” William Schaffner, MD, a professor in the division of infectious diseases at Vanderbilt University Medical Center, Nashville, Tenn., told CNN.
“This is more to reassure people who have had a reaction that that’s their immune system responding, actually in a rather good way, to the vaccine, even though it has caused them some discomfort,” said Dr. Schaffner, who was not involved in the study.

Children and COVID: Weekly cases fall to lowest level in over a year
With the third autumn of the COVID era now upon us, the discussion has turned again to a possible influenza/COVID twindemic, as well as the new-for-2022 influenza/COVID/respiratory syncytial virus tripledemic. It appears, however, that COVID may have missed the memo.
For the sixth time in the last 7 weeks, the number of new COVID cases in children fell, with just under 23,000 reported during the week of Oct. 14-20, according to the American Academy of Pediatrics and the Children’s Hospital Association. That is the lowest weekly count so far this year, and the lowest since early July of 2021, just as the Delta surge was starting. New pediatric cases had dipped to 8,500, the lowest for any week during the pandemic, a couple of weeks before that, the AAP/CHA data show.
Weekly cases have fallen by almost 75% since over 90,000 were reported for the week of Aug. 26 to Sept. 1, even as children have returned to school and vaccine uptake remains slow in the youngest age groups. Rates of emergency department visits with diagnosed COVID also have continued to drop, as have new admissions, and both are nearing their 2021 lows, according to the Centers for Disease Control and Prevention.
New vaccinations in children under age 5 years were up slightly for the most recent week (Oct. 13-19), but total uptake for that age group is only 7.1% for an initial dose and 2.9% for full vaccination. Among children aged 5-11 years, 38.7% have received at least one dose and 31.6% have completed the primary series, with corresponding figures of 71.2% and 60.9% for those aged 12-17, the CDC said on its COVID Data Tracker.
Despite the low overall numbers, though, the youngest children are, in one respect, punching above their weight when it comes to vaccinations. In the 2 weeks from Oct. 6 to Oct. 19, children under 5 years of age, who represent 5.9% of the U.S. population, received 9.2% of the initial vaccine doses administered. Children aged 5-11 years, who represent 8.7% of the total population, got just 4.2% of all first doses over those same 2 weeks, while 12- to 17-year-olds, who make up 7.6% of the population, got 3.4% of the vaccine doses, the CDC reported.
On the vaccine-approval front, the Food and Drug Administration recently announced that the new bivalent COVID-19 vaccines are now included in the emergency use authorizations for children who have completed primary or booster vaccination. The Moderna vaccine is authorized as a single-dose booster for children as young as 6 years and the Pfizer-BioNTech vaccine can be given as a single booster dose in children as young as 5 years, the FDA said.
“These bivalent COVID-19 vaccines include an mRNA component of the original strain to provide an immune response that is broadly protective against COVID-19 and an mRNA component in common between the omicron variant BA.4 and BA.5 lineages,” the FDA said.

Time to ditch clarithromycin for H. pylori?
Rates of resistance to clarithromycin among Helicobacter pylori isolates in the United States and Europe are high enough to warrant discontinuation of empiric use of proton pump inhibitor (PPI)–based triple therapy that includes the antibiotic in these regions, a new study has found.
Overall, 22.2% of participants were resistant to clarithromycin – a rate that is above the currently recommended threshold of 15% or higher for avoidance of PPI-based triple therapy that includes clarithromycin.
, study investigator William Chey, MD, professor and chief, Division of Gastroenterology and Hepatology, Michigan Medicine, Ann Arbor, said in an interview.
Judith Kim, MD, a gastroenterologist at NYU Langone Health and clinical instructor of medicine at NYU Grossman School of Medicine, who wasn’t involved in the study, agrees.
“The use of PPI-based triple therapy is still common practice despite recent recommendations to avoid clarithromycin in areas with high resistance rates,” Dr. Kim told this news organization.
“This study shows that multiple parts of the United States and Europe have high resistance rates,” rendering clarithromycin-based regimens “more likely to ineffectively eradicate H pylori,” Dr. Kim said.
The study was published online in The American Journal of Gastroenterology.
Better options now available
Guidelines advise against the use of PPI-based triple regimens with clarithromycin for H. pylori infection in areas where resistance is 15% or higher or for patients who have previously received macrolides. However, up-to-date information on H. pylori antimicrobial resistance patterns is limited, especially in the United States.
Dr. Chey and colleagues assessed resistance rates to antibiotics commonly used to treat H. pylori in isolates from 907 adults with the infection in the United States and Europe. They included four U.S. subregions and five participating European countries.
In all U.S. subregions and European countries, clarithromycin resistance rates were above 15% except possibly in the United Kingdom, where the sample size was too small to provide a reliable estimate.
Three-quarters of the clarithromycin-resistant isolates were also resistant to metronidazole.
The study also found that, overall, 1.2% of patients had isolates that were resistant to amoxicillin, and 69.2% had isolates resistant to metronidazole. Resistance patterns were similar in the United States and Europe; metronidazole resistance was the most common (50%-79% of isolates), and amoxicillin was the least common (≤ 5%).
“Overall, these data provide robust evidence to support a shift away from the default empiric prescription of triple combinations containing a PPI and clarithromycin for H. pylori infection in the United States and Europe,” the study team writes.
The high prevalence of resistance, including dual resistance, highlights the need for antibiotic stewardship and resistance surveillance, as well as novel treatment strategies for H. pylori infection, they add.
Last spring, as previously reported, the United States Food and Drug Administration approved two vonoprazan-based treatments for H. pylori: Voquezna Triple Pak (vonoprazan, amoxicillin, clarithromycin) and Voquezna Dual Pak (vonoprazan, amoxicillin), both from Phathom Pharmaceuticals.
“Vonoprazan-based treatment may be superior to standard PPI triple therapy for clarithromycin-resistant infections based on prior studies and is a potential good option,” Dr. Kim said.
Still, she added, she “would most likely first recommend regimens that do not have clarithromycin, such as bismuth quadruple therapy.”
Study’s importance
Because the study drew upon the largest dataset to date on U.S. resistance rates, it should be used to more precisely guide first-line therapy decisions, said Richard Peek, Jr., MD, professor of medicine and director of gastroenterology at Vanderbilt University Medical Center, Nashville, Tenn.
“To date, there has been a dearth of information in the United States regarding H. pylori resistance rates, which has often led to the use of ineffective empiric therapies and inappropriate exposure to antibiotics,” Dr. Peek, who wasn’t involved in the study, told this news organization.
“These data are particularly exciting when viewed within the context of new genomic sequencing tests that can determine H. pylori resistance patterns using DNA isolated from the stomach or the stool,” he said.
Dr. Peek agreed that the recent approval of vonoprazan-based therapies “adds another regimen to the therapeutic armamentarium available for eradicating H. pylori, and its value seems to be particularly beneficial for eradication failures.”
The research was funded by Phathom Pharmaceuticals. Dr. Chey is a board member of the American College of Gastroenterology, GI on Demand, the International Foundation of Functional GI Disorders, and the Rome Foundation. He has received compensation as a consultant from AbbVie, Alfasigma, Allakos, Alnylam, Bayer, BioAmerica, Cosmo, Intrinsic Medicine, Ironwood Pharmaceuticals, QOL Medical, Nestle, Phathom Pharmaceuticals, RedHill Biopharma, Salix/Valeant, Takeda, Urovant, and Vibrant; grant/research support from BioAmerica, Commonwealth Diagnostics International, QOL Medical, Salix, and Vibrant; owns stock/stock options in GI on Demand and Modify Health; and owns patents relating to methods and kits for identifying food sensitivities and intolerances, digital manometry, and a rectal expulsion device. Dr. Peek and Dr. Kim report no relevant financial relationships.

Resistance patterns were similar in the United States and Europe; metronidazole resistance was the most common (50%-79% of isolates), and amoxicillin was the least common (≤ 5%).
“Overall, these data provide robust evidence to support a shift away from the default empiric prescription of triple combinations containing a PPI and clarithromycin for H. pylori infection in the United States and Europe,” the study team writes.
The high prevalence of resistance, including dual resistance, highlights the need for antibiotic stewardship and resistance surveillance, as well as novel treatment strategies for H. pylori infection, they add.
Last spring, as previously reported, the United States Food and Drug Administration approved two vonoprazan-based treatments for H. pylori: Voquezna Triple Pak (vonoprazan, amoxicillin, clarithromycin) and Voquezna Dual Pak (vonoprazan, amoxicillin), both from Phathom Pharmaceuticals.
“Vonoprazan-based treatment may be superior to standard PPI triple therapy for clarithromycin-resistant infections based on prior studies and is a potential good option,” Dr. Kim said.
Still, she added, she “would most likely first recommend regimens that do not have clarithromycin, such as bismuth quadruple therapy.”
Study’s importance
Because the study drew upon the largest dataset to date on U.S. resistance rates, it should be used to more precisely guide first-line therapy decisions, said Richard Peek, Jr., MD, professor of medicine and director of gastroenterology at Vanderbilt University Medical Center, Nashville, Tenn.
“To date, there has been a dearth of information in the United States regarding H. pylori resistance rates, which has often led to the use of ineffective empiric therapies and inappropriate exposure to antibiotics,” Dr. Peek, who wasn’t involved in the study, told this news organization.
“These data are particularly exciting when viewed within the context of new genomic sequencing tests that can determine H. pylori resistance patterns using DNA isolated from the stomach or the stool,” he said.
Dr. Peek agreed that the recent approval of vonoprazan-based therapies “adds another regimen to the therapeutic armamentarium available for eradicating H. pylori, and its value seems to be particularly beneficial for eradication failures.”
The research was funded by Phathom Pharmaceuticals.

Rates of resistance to clarithromycin among Helicobacter pylori isolates in the United States and Europe are high enough to warrant discontinuation of empiric use of proton pump inhibitor (PPI)–based triple therapy that includes the antibiotic in these regions, a new study has found.
Overall, 22.2% of participants were resistant to clarithromycin – a rate that is above the currently recommended threshold of 15% or higher for avoidance of PPI-based triple therapy that includes clarithromycin.
, study investigator William Chey, MD, professor and chief, Division of Gastroenterology and Hepatology, Michigan Medicine, Ann Arbor, said in an interview.
Judith Kim, MD, a gastroenterologist at NYU Langone Health and clinical instructor of medicine at NYU Grossman School of Medicine, who wasn’t involved in the study, agrees.
“The use of PPI-based triple therapy is still common practice despite recent recommendations to avoid clarithromycin in areas with high resistance rates,” Dr. Kim told this news organization.
“This study shows that multiple parts of the United States and Europe have high resistance rates,” rendering clarithromycin-based regimens “more likely to ineffectively eradicate H pylori,” Dr. Kim said.
The study was published online in The American Journal of Gastroenterology.
Better options now available
Guidelines advise against the use of PPI-based triple regimens with clarithromycin for H. pylori infection in areas where resistance is 15% or higher or for patients who have previously received macrolides. However, up-to-date information on H. pylori antimicrobial resistance patterns is limited, especially in the United States.
Dr. Chey and colleagues assessed resistance rates to antibiotics commonly used to treat H. pylori in isolates from 907 adults with the infection in the United States and Europe. They included four U.S. subregions and five participating European countries.
In all U.S. subregions and European countries, clarithromycin resistance rates were above 15% except possibly in the United Kingdom, where the sample size was too small to provide a reliable estimate.
Three-quarters of the clarithromycin-resistant isolates were also resistant to metronidazole.
The study also found that, overall, 1.2% of patients had isolates that were resistant to amoxicillin, and 69.2% had isolates resistant to metronidazole. Resistance patterns were similar in the United States and Europe; metronidazole resistance was the most common (50%-79% of isolates), and amoxicillin was the least common (≤ 5%).

Life expectancy 6.3 years shorter for Black MSM with HIV
WASHINGTON –
Lead author Katherine Rich, MPH, a student at Harvard Medical School, Boston, presented the data during an annual scientific meeting on infectious diseases.
“Substantial disparities in care exist between Black and White MSM here in the United States,” she said. “The 2030 goals of the EHE [Ending the HIV Epidemic in the U.S. initiative] won’t be met until HIV-related disparities are reduced.”
Using modeling, the team was able to measure both the gaps and the potential of interventions to address those gaps.
- The team found that improving engagement in care had the largest benefit in narrowing the gap. Improving engagement and retention in care, they write, would result in a gain of 1.4 life-years for Black MSM and 1 year for White MSM.
- Annual testing would add 0.6 life-years for Black MSM and 0.3 life-years for White MSM, compared with standard care.
- In simulating viral suppression, the model-predicted gain would be 1.1 years for Black MSM and 0.3 for White.
Furthermore, a combination of annual testing, 95% engagement in care, and 95% virologic suppression would add 3.4 years for Black MSM (more than double the increase in life-years for any one intervention) and 1.6 years for their White counterparts, the research suggests.
The researchers projected life expectancy from age 15 to be 52.2 years for Black MSM (or 67.2 years old) and 58.5 years from age 15 for White MSM (or 73.5 years old), a difference of 6.3 years.
Kathleen McManus, MD, assistant professor of medicine in infectious diseases and international health at the University of Virginia, Charlottesville, said in an interview that the projected gap in years of life should be a call to action. Dr. McManus was not involved with the study.
Life expectancy gap ‘alarming’
“It is alarming that with current usual HIV care Black MSM with HIV have 6.3 fewer years of life expectancy than White MSM,” she said. “Black MSM having lower retention in care and a lower rate of viral suppression than White MSM demonstrates that there is a problem with our current health care delivery to Black MSM.”
With qualitative, community-engaged research, she said, “we need to ask the Black MSM community what care innovations they need – and then we need clinics and organizations to make the identified changes.”
Researchers used the validated CEPAC (Cost-Effectiveness of Preventing AIDS Complications) microsimulation HIV model to project life expectancy. Using data from the United States Centers for Disease Control and Prevention, they estimated the average age at HIV infection to be 26.8 years for Black MSM and 35 years for White MSM.
They estimated the proportion of time that MSM with diagnosed HIV are retained in care to be 75.2% for Black MSM and 80.6% for White MSM. They calculated the proportion who achieve virologic suppression to be 82% for Black MSM and 91.2% for White MSM.
Senior author Emily P. Hyle, MD, associate professor of medicine at Harvard and infectious diseases physician at Massachusetts General Hospital, both in Boston, said in a press conference before the presentation that strategies to narrow the gap will look different by region.
“Our study highlights that if you can find effective interventions, the effect can be incredibly large. These are very large differences in life-years and life expectancies,” she said.
Ms. Rich gave an example of promising interventions by pointing to work by study coauthor Aima Ahonkhai, MD, MPH, assistant professor of medicine at Vanderbilt University, Nashville, Tenn., who has received federal funding to pursue research on whether preventive care outreach in barbershops can improve prevention for Black men with HIV.
Ms. Rich noted that the modeling has limitations in that it focused on health outcomes and did not simulate transmissions. Results also reflect national data and not local HIV care continuums, which, she acknowledged, differ substantially.
Dr. McManus and the study authors have reported no relevant financial relationships.

Worse COVID outcomes seen with gout, particularly in women
People with gout, especially women, appear to be at higher risk for poor COVID-19 outcomes, including hospitalization and death, regardless of COVID-19 vaccination status, researchers suggest.
“We found that the risks of SARS-CoV-2 infection, 30-day hospitalization, and 30-day death among individuals with gout were higher than the general population irrespective of the vaccination status,” lead study author Dongxing Xie, MD, PhD, Xiangya Hospital, Central South University, Changsha, China, and his colleagues write in their large population study. “This finding informs individuals with gout, especially women, that additional measures, even after vaccination, should be considered in order to mitigate the risk of SARS-CoV-2 infection and its severe sequelae.”
People with gout, the most common inflammatory arthritis, often have other conditions that are linked to higher risk for SARS-CoV-2 infection and poor outcomes as well, including obesity, cardiovascular disease, and chronic kidney disease, the authors write. And elevated serum urate may contribute to inflammation and possible COVID-19 complications. But unlike in the case of diseases such as lupus and rheumatoid arthritis, little is known about SARS-CoV-2 infection risk among patients with gout.
As reported in Arthritis & Rheumatology, Dr. Xie and his research team used the Health Improvement Network ([THIN], now called IQVIA Medical Research Database) repository of medical conditions, demographics, and other details of around 17 million people in the United Kingdom to estimate the risk for SARS-CoV-2 infection, hospitalization, and death in people with gout. They compared those outcomes with outcomes of people without gout and compared outcomes of vaccinated vs. nonvaccinated participants.
From December 2020 through October 2021, the researchers investigated the risk for SARS-CoV-2 breakthrough infection in vaccinated people between age 18 and 90 years who had gout and were hospitalized within 30 days after the infection diagnosis or who died within 30 days after the diagnosis. They compared these outcomes with the outcomes of people in the general population without gout after COVID-19 vaccination. They also compared the risk for SARS-CoV-2 infection and its severe outcomes between individuals with gout and the general population among unvaccinated people.
They weighted these comparisons on the basis of age, sex, body mass index, socioeconomic deprivation index score, region, and number of previous COVID-19 tests in one model. A more fully adjusted model also weighted the comparisons for lifestyle factors, comorbidities, medications, and healthcare utilization.
The vaccinated cohort consisted of 54,576 people with gout and 1,336,377 without gout from the general population. The unvaccinated cohort included 61,111 individuals with gout and 1,697,168 individuals without gout from the general population.
Women more likely to be hospitalized and die
The risk for breakthrough infection in the vaccinated cohort was significantly higher among people with gout than among those without gout in the general population, particularly for men, who had hazard ratios (HRs) ranging from 1.22 with a fully adjusted exposure score to 1.30 with a partially adjusted score, but this was not seen in women. The overall incidence of breakthrough infection per 1,000 person-months for these groups was 4.68 with gout vs. 3.76 without gout.
The researchers showed a similar pattern of a higher rate of hospitalizations for people with gout vs. without (0.42/1,000 person-months vs. 0.28); in this case, women had higher risks than did men, with HRs for women ranging from 1.55 with a fully adjusted exposure score to 1.91 with a partially adjusted score, compared with 1.22 and 1.43 for men, respectively.
People with gout had significantly higher mortality than did those without (0.06/1,000 person-months vs. 0.04), but the risk for death was only higher for women, with HRs calculated to be 2.23 in fully adjusted exposure scores and 3.01 in partially adjusted scores.
These same comparisons in the unvaccinated cohort all went in the same direction as did those in the vaccinated cohort but showed higher rates for infection (8.69/1,000 person-months vs. 6.89), hospitalization (2.57/1,000 person-months vs. 1.71), and death (0.65/1,000 person-months vs. 0.53). Similar sex-specific links between gout and risks for SARS-CoV-2 infection, hospitalization, and death were seen in the unvaccinated cohort.
Patients with gout and COVID-19 need close monitoring
Four experts who were not involved in the study encourage greater attention to the needs of patients with gout.
Pamela B. Davis, MD, PhD, research professor at Case Western Reserve University, Cleveland, told this news organization, “This study brings to attention yet another potentially vulnerable group for physicians to monitor closely if they are infected with SARS-CoV-2.
“It is not clear why women with gout are more vulnerable, but fewer women than men were in the cohort with gout, and the confidence intervals for the results in women were, in general, larger,” she said.
“The authors suggest that women with gout tend to be older and have more comorbidities than men with gout,” Dr. Davis added. “The excess risk diminishes when the model is fully adjusted for comorbidities, such as obesity, hypertension, or heart disease, suggesting that already-known antecedents of infection severity account for a great deal of the excess risk.”
Kevin D. Deane, MD, PhD, associate professor of medicine and chair in rheumatology research at the University of Colorado at Denver, Aurora, advises physicians to keep in mind other conditions linked with increased risk for severe COVID-19, including advanced age; heart, lung, or kidney problems; and autoimmune diseases.
“I would be very cautious about the finding that there was not a difference in outcomes in individuals with gout based on vaccination status,” he cautioned, urging clinicians to “still strongly recommend vaccines according to guidelines.”
Sarah E. Waldman, MD, associate clinical professor of infectious diseases at UC Davis Health in Sacramento, Calif., called the study interesting but not surprising.
“The reason for increased risk for COVID-19 infection among those with gout may have to do with their underlying inflammatory state. Additional research needs to be done on this topic.
“Retrospective population-based cohort studies can be difficult to interpret due to biases,” she added. Associations identified in this type of study do not determine causation.
“As the researchers noted, those with gout tend to have additional comorbidities as well as advanced age,” she said. “They may also seek medical care more often and be tested for SARS-CoV-2 more frequently.”
Dr. Waldman advises clinicians to counsel patients with gout about their potential increased infection risk and ways they can protect themselves, including COVID-19 vaccinations.
“The strong association between gout and COVID-19 infection could involve coexisting conditions such as diabetes, hypertension, cardiovascular disease, and chronic kidney disease,” Dr. Aung added.
Earlier studies show links between gout and severe COVID-19 outcomes
Lead author Kanon Jatuworapruk, MD, PhD, of Thammasat University in Pathumthani, Thailand, and his colleagues investigated characteristics and outcomes of people with gout who were hospitalized for COVID-19 between March 2020 and October 2021, using data from the COVID-19 Global Rheumatology Alliance registry.
“This cohort of people with gout and COVID-19 who were hospitalized had high frequencies of ventilatory support and death,” the authors write in ACR Open Rheumatology . “This suggests that patients with gout who were hospitalized for COVID-19 may be at risk of poor outcomes, perhaps related to known risk factors for poor outcomes, such as age and presence of comorbidity.”
In their study, the average age of the 163 patients was 63 years, and 85% were men. Most lived in the Western Pacific Region and North America, and 46% had two or more comorbidities, most commonly hypertension, cardiovascular disease, diabetes, chronic kidney disease, and obesity. The researchers found that:
- Sixty-eight percent of the cohort required supplemental oxygen or ventilatory support during hospitalization.
- Sixteen percent of deaths were related to COVID-19, with 73% of deaths occurring in people with two or more comorbidities.
Ruth K. Topless, assistant research fellow in the department of biochemistry at the University of Otago in Dunedin, New Zealand, is the lead author on a study she and her colleagues are conducting using the UK Biobank databases of 459,837 participants in the United Kingdom, including 15,871 people with gout, through April 6, 2021, to investigate whether gout is a risk factor for diagnosis of COVID-19 and COVID-19–related death.
“Gout is a risk factor for COVID-19-related death in the UK Biobank cohort, with an increased risk in women with gout, which was driven by risk factors independent of the metabolic comorbidities of gout,” the researchers conclude in The Lancet Rheumatology.
In their study, gout was linked with COVID-19 diagnosis (odds ratio, 1.20; 95% confidence interval, 1.11-1.29) but not with risk for COVID-19–related death in the group of patients with COVID-19 (OR, 1.20; 95% CI, 0.96-1.51). In the entire cohort, gout was linked with COVID-19–related death (OR, 1.29; 95% CI, 1.06-1.56); women with gout were at increased risk for COVID-19–related death (OR, 1.98; 95% CI, 1.34-2.94), but men with gout were not (OR, 1.16; 95% CI, 0.93-1.45). The risk for COVID-19 diagnosis was significant in the nonvaccinated group (OR, 1.21; 95% CI, 1.11-1.30) but not in the vaccinated group (OR, 1.09; 95% CI, 0.65-1.85).
Editorial authors join in recommending further related research
In a commentary in The Lancet Rheumatology about the UK Biobank and other related research, Christoffer B. Nissen, MD, of University Hospital of Southern Denmark in Sonderborg, and his co-authors call the Topless and colleagues study “an elegantly conducted analysis of data from the UK Biobank supporting the hypothesis that gout needs attention in patients with COVID-19.”
Further studies are needed to investigate to what degree a diagnosis of gout is a risk factor for COVID-19 and whether treatment modifies the risk of a severe disease course,” they write. “However, in the interim, the results of this study could be considered when risk stratifying patients with gout in view of vaccination recommendations and early treatment interventions.”
Each of the three studies received grant funding. Several of the authors of the studies report financial involvements with pharmaceutical companies. All outside experts commented by email and report no relevant financial involvements.

These same comparisons in the unvaccinated cohort all went in the same direction as did those in the vaccinated cohort but showed higher rates for infection (8.69/1,000 person-months vs. 6.89), hospitalization (2.57/1,000 person-months vs. 1.71), and death (0.65/1,000 person-months vs. 0.53). Similar sex-specific links between gout and risks for SARS-CoV-2 infection, hospitalization, and death were seen in the unvaccinated cohort.
Patients with gout and COVID-19 need close monitoring
Four experts who were not involved in the study encourage greater attention to the needs of patients with gout.
Pamela B. Davis, MD, PhD, research professor at Case Western Reserve University, Cleveland, told this news organization, “This study brings to attention yet another potentially vulnerable group for physicians to monitor closely if they are infected with SARS-CoV-2.
“It is not clear why women with gout are more vulnerable, but fewer women than men were in the cohort with gout, and the confidence intervals for the results in women were, in general, larger,” she said.
“The authors suggest that women with gout tend to be older and have more comorbidities than men with gout,” Dr. Davis added. “The excess risk diminishes when the model is fully adjusted for comorbidities, such as obesity, hypertension, or heart disease, suggesting that already-known antecedents of infection severity account for a great deal of the excess risk.”
Kevin D. Deane, MD, PhD, associate professor of medicine and chair in rheumatology research at the University of Colorado at Denver, Aurora, advises physicians to keep in mind other conditions linked with increased risk for severe COVID-19, including advanced age; heart, lung, or kidney problems; and autoimmune diseases.
“I would be very cautious about the finding that there was not a difference in outcomes in individuals with gout based on vaccination status,” he cautioned, urging clinicians to “still strongly recommend vaccines according to guidelines.”
Sarah E. Waldman, MD, associate clinical professor of infectious diseases at UC Davis Health in Sacramento, Calif., called the study interesting but not surprising.
“The reason for increased risk for COVID-19 infection among those with gout may have to do with their underlying inflammatory state. Additional research needs to be done on this topic.
“Retrospective population-based cohort studies can be difficult to interpret due to biases,” she added. Associations identified in this type of study do not determine causation.
“As the researchers noted, those with gout tend to have additional comorbidities as well as advanced age,” she said. “They may also seek medical care more often and be tested for SARS-CoV-2 more frequently.”
Dr. Waldman advises clinicians to counsel patients with gout about their potential increased infection risk and ways they can protect themselves, including COVID-19 vaccinations.
“The strong association between gout and COVID-19 infection could involve coexisting conditions such as diabetes, hypertension, cardiovascular disease, and chronic kidney disease,” Dr. Aung added.
Earlier studies show links between gout and severe COVID-19 outcomes
Lead author Kanon Jatuworapruk, MD, PhD, of Thammasat University in Pathumthani, Thailand, and his colleagues investigated characteristics and outcomes of people with gout who were hospitalized for COVID-19 between March 2020 and October 2021, using data from the COVID-19 Global Rheumatology Alliance registry.
“This cohort of people with gout and COVID-19 who were hospitalized had high frequencies of ventilatory support and death,” the authors write in ACR Open Rheumatology . “This suggests that patients with gout who were hospitalized for COVID-19 may be at risk of poor outcomes, perhaps related to known risk factors for poor outcomes, such as age and presence of comorbidity.”
In their study, the average age of the 163 patients was 63 years, and 85% were men. Most lived in the Western Pacific Region and North America, and 46% had two or more comorbidities, most commonly hypertension, cardiovascular disease, diabetes, chronic kidney disease, and obesity. The researchers found that:
- Sixty-eight percent of the cohort required supplemental oxygen or ventilatory support during hospitalization.
- Sixteen percent of deaths were related to COVID-19, with 73% of deaths occurring in people with two or more comorbidities.
Ruth K. Topless, assistant research fellow in the department of biochemistry at the University of Otago in Dunedin, New Zealand, is the lead author on a study she and her colleagues are conducting using the UK Biobank databases of 459,837 participants in the United Kingdom, including 15,871 people with gout, through April 6, 2021, to investigate whether gout is a risk factor for diagnosis of COVID-19 and COVID-19–related death.
“Gout is a risk factor for COVID-19-related death in the UK Biobank cohort, with an increased risk in women with gout, which was driven by risk factors independent of the metabolic comorbidities of gout,” the researchers conclude in The Lancet Rheumatology.
In their study, gout was linked with COVID-19 diagnosis (odds ratio, 1.20; 95% confidence interval, 1.11-1.29) but not with risk for COVID-19–related death in the group of patients with COVID-19 (OR, 1.20; 95% CI, 0.96-1.51). In the entire cohort, gout was linked with COVID-19–related death (OR, 1.29; 95% CI, 1.06-1.56); women with gout were at increased risk for COVID-19–related death (OR, 1.98; 95% CI, 1.34-2.94), but men with gout were not (OR, 1.16; 95% CI, 0.93-1.45). The risk for COVID-19 diagnosis was significant in the nonvaccinated group (OR, 1.21; 95% CI, 1.11-1.30) but not in the vaccinated group (OR, 1.09; 95% CI, 0.65-1.85).
Editorial authors join in recommending further related research
In a commentary in The Lancet Rheumatology about the UK Biobank and other related research, Christoffer B. Nissen, MD, of University Hospital of Southern Denmark in Sonderborg, and his co-authors call the Topless and colleagues study “an elegantly conducted analysis of data from the UK Biobank supporting the hypothesis that gout needs attention in patients with COVID-19.”
Further studies are needed to investigate to what degree a diagnosis of gout is a risk factor for COVID-19 and whether treatment modifies the risk of a severe disease course,” they write. “However, in the interim, the results of this study could be considered when risk stratifying patients with gout in view of vaccination recommendations and early treatment interventions.”
Each of the three studies received grant funding. Several of the authors of the studies report financial involvements with pharmaceutical companies. All outside experts commented by email and report no relevant financial involvements.

People with gout, especially women, appear to be at higher risk for poor COVID-19 outcomes, including hospitalization and death, regardless of COVID-19 vaccination status, researchers suggest.
“We found that the risks of SARS-CoV-2 infection, 30-day hospitalization, and 30-day death among individuals with gout were higher than the general population irrespective of the vaccination status,” lead study author Dongxing Xie, MD, PhD, Xiangya Hospital, Central South University, Changsha, China, and his colleagues write in their large population study. “This finding informs individuals with gout, especially women, that additional measures, even after vaccination, should be considered in order to mitigate the risk of SARS-CoV-2 infection and its severe sequelae.”
People with gout, the most common inflammatory arthritis, often have other conditions that are linked to higher risk for SARS-CoV-2 infection and poor outcomes as well, including obesity, cardiovascular disease, and chronic kidney disease, the authors write. And elevated serum urate may contribute to inflammation and possible COVID-19 complications. But unlike in the case of diseases such as lupus and rheumatoid arthritis, little is known about SARS-CoV-2 infection risk among patients with gout.
As reported in Arthritis & Rheumatology, Dr. Xie and his research team used the Health Improvement Network ([THIN], now called IQVIA Medical Research Database) repository of medical conditions, demographics, and other details of around 17 million people in the United Kingdom to estimate the risk for SARS-CoV-2 infection, hospitalization, and death in people with gout. They compared those outcomes with outcomes of people without gout and compared outcomes of vaccinated vs. nonvaccinated participants.
From December 2020 through October 2021, the researchers investigated the risk for SARS-CoV-2 breakthrough infection in vaccinated people between age 18 and 90 years who had gout and were hospitalized within 30 days after the infection diagnosis or who died within 30 days after the diagnosis. They compared these outcomes with the outcomes of people in the general population without gout after COVID-19 vaccination. They also compared the risk for SARS-CoV-2 infection and its severe outcomes between individuals with gout and the general population among unvaccinated people.
They weighted these comparisons on the basis of age, sex, body mass index, socioeconomic deprivation index score, region, and number of previous COVID-19 tests in one model. A more fully adjusted model also weighted the comparisons for lifestyle factors, comorbidities, medications, and healthcare utilization.
The vaccinated cohort consisted of 54,576 people with gout and 1,336,377 without gout from the general population. The unvaccinated cohort included 61,111 individuals with gout and 1,697,168 individuals without gout from the general population.
Women more likely to be hospitalized and die
The risk for breakthrough infection in the vaccinated cohort was significantly higher among people with gout than among those without gout in the general population, particularly for men, who had hazard ratios (HRs) ranging from 1.22 with a fully adjusted exposure score to 1.30 with a partially adjusted score, but this was not seen in women. The overall incidence of breakthrough infection per 1,000 person-months for these groups was 4.68 with gout vs. 3.76 without gout.
The researchers showed a similar pattern of a higher rate of hospitalizations for people with gout vs. without (0.42/1,000 person-months vs. 0.28); in this case, women had higher risks than did men, with HRs for women ranging from 1.55 with a fully adjusted exposure score to 1.91 with a partially adjusted score, compared with 1.22 and 1.43 for men, respectively.
People with gout had significantly higher mortality than did those without (0.06/1,000 person-months vs. 0.04), but the risk for death was only higher for women, with HRs calculated to be 2.23 in fully adjusted exposure scores and 3.01 in partially adjusted scores.
