People with untreatable dystrophic epidermolysis bullosa (DEB) may soon have access to an investigational gene therapy delivered in a topical gel that is currently under review by the Food and Drug Administration.

In a phase 3 study of patients with DEB, “we found that repeated topical application of B-VEC [beremagene geperpavec], an HSV-1–based gene therapy, resulted in a greater likelihood of complete wound healing than the topical application of placebo at up to 6 months,” the authors wrote. The study was published in The New England Journal of Medicine. “Longer and larger trials are warranted to determine the durability of effect and risks of this approach,” the authors noted.

“The results prove that B-VEC, the first topical in vivo gene therapy to reach late-stage development, can heal DEB,” senior author M. Peter Marinkovich, MD, associate professor of dermatology at Stanford University, Redwood City, Calif., said in an interview.

“In the past, DEB was a very specialized disease that only a handful of dermatologists would see but could not do much to treat,” he said. “With gene therapy, many more dermatologists who may not be familiar with DEB will be able to treat these patients in their offices.” It is expected that nurses will be able to administer the treatment to patients at home, he added.
 

Rare, life-threatening, genetic blistering disease

DEB, a rare disease that affects one to three persons per million in the United States, is caused by mutations in the COL7A1 gene that encodes the alpha-1 chain of collagen type VII (C7) protein. C7 forms the anchoring fibrils that attach the epidermis to the underlying dermal connective tissue.

COL71A mutations that lead to defective, decreased, or absent C7 can make the skin so fragile it tears with the slightest touch. This has led to patients being called “butterfly children.” Epithelial tissues blister and scar, causing esophageal and genitourinary strictures, adhesion of digits, malnutrition, anemia, infection, and bothersome itch and pain. Morbidity and mortality are high. The leading cause of death in adults is chronic wounds leading to aggressive squamous cell cancers.
 

The first therapy for DEB, under FDA review

B-VEC restores C7 protein by using an engineered replication-defective herpes simplex virus type 1 (HSV-1) vector to deliver the COL7A1 gene directly to skin cells to restore functional C7 protein fibrils that stabilize the skin structure.

On the basis of manufacturing information submitted to the FDA in December 2022, the agency extended the date for a decision on approval by 3 months, to May 19, 2023, according to a statement from Krystal Biotech, the developer of B-VEC and the sponsor of the NEJM study.

Dr. Marinkovich and his colleagues conducted the double-blind, randomized, controlled GEM-3 trial of B-VEC at three sites in the United States. The 31 study participants ranged in age from 1 to 44 years (median age, 16 years) and had genetically confirmed DEB (30 with the recessive form and 1 with the dominant form).

For each participant, a pair of wounds was chosen that were matched in size, region, and appearance. The wounds within each pair were randomly allocated to receive weekly applications of either B-VEC or placebo gel for 26 weeks.

The results of the study included the following:

• Complete healing at 6 months occurred in 67% of the wounds treated with B-VEC (including a wound in the patient with dominant DEB), vs. 22% of those who received placebo (95% confidence interval [CI], 24-68; P = .002).
• Complete healing at 3 months occurred in 71% of the wounds treated with B-VEC, vs. 20% of those who received placebo (95% CI, 29-73; P < .001).
• The mean change from baseline to week 22 in pain severity during wound-dressing changes for patients aged 6 years and older, as determined on the basis of a visual analogue scale, was –0.88 with B-VEC, vs. –0.71 with placebo (adjusted least-squares mean difference, –0.61; 95% CI, –1.10 to –0.13); similar mean changes were seen at weeks 24 and 26.
• Among all patients, 58% had at least one adverse event. Most adverse events were mild or moderate. The most common were pruritus, chills, and squamous cell carcinoma (SCC), which were reported in three patients each (SCC cases occurred at wound sites that had not been exposed to B-VEC or placebo). Serious adverse events, which were unrelated to the treatment, occurred in three patients: diarrhea, anemia, cellulitis, and a positive blood culture related to a hemodialysis catheter.

“With the ability to treat patients with topical gene therapy, dermatology is entering a new age of treatment possibilities,” Dr. Marinkovich said in the interview.

The researchers were surprised that the redosable in vivo gene therapy worked so well, he added. In vivo gene therapy has been plagued by the occurrence of immune reactions against the viral vectors used, Dr. Marinkovich explained. But because the herpes simplex virus has evolved to evade the immune system, his team could use the viral vector every week for 6 months without inflammatory reactions.

“The immune system’s inability to fight off or get rid of the herpes simplex vector makes it bad as a disease, but as a gene therapy vector, it provides a huge advantage,” he added.

Asked to comment on the results, Christen Ebens, MD, MPH, assistant professor in the department of pediatrics at the University of Minnesota, Minneapolis, whose clinical and research interests include EB, called the results exciting for patients, families, and doctors.

“Side effects were minimal, and importantly, use of the replication-incompetent HSV vector means that the payload gene does not integrate into the patient’s DNA,” Dr. Ebens, who was not involved in the study, said in an interview. “B-VEC is not a lifelong cure but potentially an effective maintenance therapy requiring repeated doses,” she added.

Although the researchers found no clinically important immune reactions to B-VEC, Dr. Ebens said she would like to see results from longer studies of the treatment. “We will want to see that patients do not produce neutralizing antibodies against B-VEC or its components, as such antibodies may yield the treatment ineffective or cause significant side effects.”

In an interview, Vanessa R. Holland, MD, associate clinical professor in the division of dermatology at UCLA Health, Burbank, Calif., who was not involved in the study, said that “topical replication-defective HSV-1 is a brilliant vector to deliver the depleted collagen.” She added that “such a vehicle may significantly alter management of these disorders and improve or extend lives by minimizing potentially fatal complications.”

Paras P. Vakharia, MD, PharmD, assistant professor of dermatology at Northwestern University, Chicago, who was not involved in the study, was surprised by the high percentage of healed wounds and wounds that remained healed over time.

B-VEC for treating other conditions

Dr. Marinkovich noted that an ongoing phase 1 clinical trial, also sponsored by Krystal Biotech, is using the HSV-1 vector to deliver a different biologic (KB105) to establish dose and safety in the treatment of ichthyosis. He added that he would like to explore the use of B-VEC to treat DEB at mucosal surfaces, including inside the mouth, the eye, and the esophagus.

Authors of two editorials that accompanied the study also referred to other conditions B-VEC might treat.

This study “highlights potential future investigations,” David V. Schaffer, PhD, professor of chemical and biomolecular engineering, bioengineering, and molecular and cell biology at the University of California, Berkeley, wrotes in one of the editorials.

Important considerations he mentioned include the likelihood of the treatment becoming lifelong; the inability of HSV to penetrate intact skin, making B-VEC unsuitable for preventing the development of new wounds; and the inability of this treatment to treat EB lesions along the digestive tract. “This important trial builds on and extends gene-therapy successes to new targets and vectors, an advance for patients,” he added.

In the second editorial, Aimee S. Payne, MD, PhD, professor of dermatology at the University of Pennsylvania, Philadelphia, raised the question of whether B-VEC’s clinical success for treating DEB can translate to other genetic diseases.

“Formulations for ophthalmic, oral-gastrointestinal, or respiratory delivery would be of great value to address the extracutaneous manifestations of epidermolysis bullosa and other genetic diseases,” she wrote.

Referring to an ongoing trial of a topical gene therapy for cystic fibrosis that is delivered by a nebulizer, Dr. Payne noted, “Ultimately, the completion of clinical trials such as this one will be required to determine whether HSV-1–mediated gene delivery can go more than skin deep.”

Earlier data and more details of the study were presented in a poster at the annual meeting of the Society for Pediatric Dermatology in July 2022.

Dr. Marinkovich has disclosed no relevant financial relationships. Several coauthors are employees of or have other financial relationships with Krystal Biotech, the study’s sponsor and the developer of beremagene geperpavec. Dr. Schaffer and Dr. Payne have financial relationships with the pharmaceutical industry. Dr. Ebens, Dr. Holland, and Dr. Vakharia have disclosed no relevant financial relationships.

Corticosteroid (CS) injections may worsen progression of knee osteoarthritis as seen on radiography and whole-knee MRI. Injecting hyaluronic acid (HA) instead, or managing the condition without injections, may better preserve knee structure and cartilage, according to results of two related studies presented at the annual meeting of the Radiological Society of North America.

The findings come nonrandomized, observational cohort studies, leading knee OA experts to call for further study in randomized trial settings. In the meantime, shared decision-making between patients and clinicians is advised on the use of these injections.

For knee OA, most patients seek a noninvasive treatment for symptomatic relief. “At least 10% of these patients undergo local treatment with injectable corticosteroids or hyaluronic acid,” the lead author of one of the studies, Upasana Upadhyay Bharadwaj, MD, research fellow in musculoskeletal radiology at the University of California, San Francisco, said in a video press release.

Researchers in both studies used data and images from the Osteoarthritis Initiative (OAI), a multicenter, longitudinal, observational study of 4,796 U.S. patients aged 45-79 years with knee OA. Participants were enrolled from February 2004 to May 2006.

The OAI maintains a natural history database of information regarding participants’ clinical evaluation data, x-rays, MRI scans, and a biospecimen repository. Data are available to researchers worldwide.
 

Two studies draw similar conclusions

In one study, Dr. Bharadwaj and colleagues found that HA injections appeared to show decreased knee OA progression in bone marrow lesions.

They investigated 8 patients who received one CS injection, 12 who received one HA injection, and 40 control persons who received neither treatment. Participants were propensity-score matched by age, sex, body mass index (BMI), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Physical Activity Scale for the Elderly (PASE).

The researchers semiquantitatively graded three Tesla MRI scans that had been obtained at baseline, 2 years before the injection, and 2 years after the injection, using whole-organ MRI score (WORMS) for the meniscus, bone marrow lesions, cartilage, joint effusion, and ligaments.

They quantified OA progression using the difference in WORMS between baseline and 2-year follow-up, and they used linear regression models, adjusted for age, sex, BMI, KL grade, WOMAC, and PASE, to identify the link between type of injection and progression of WORMS.

At 2 years, the authors found a significant association between CS injection and postinjection progression of WORMS over 2 years for the knee overall, the lateral meniscus, lateral cartilage, and medial cartilage. There was no significant link between HA injection and postinjection progression of WORMS or between either injection type and progression of pain, as quantified by WOMAC. There was also no significant difference in progression of WORMS over the 2 years prior to injection for CS and HA injections.

“Corticosteroid injections must be administered with caution with respect to long-term effects on osteoarthritis,” Dr. Bharadwaj advised. “Hyaluronic acid injections, on the other hand, may slow down progression of knee osteoarthritis and alleviate long-term effects while offering similar symptomatic relief to corticosteroid injections. Overall, they are perhaps a safer alternative when looking at medium- and long-term disease course of knee osteoarthritis.”

In the second study, lead author Azad Darbandi, MS, a fourth-year medical student at Chicago Medical School, North Chicago, and colleagues found that patients who received CS injections experienced significantly more medial joint space narrowing.

They identified 210 knees with imaging at baseline and at 48 months that received CS injections, and 59 that received HA injections; 6,827 knees served as controls. The investigators matched 50 patients per group on the basis of confounding factors, which included age, sex, BMI, comorbidities, surgery, and semiquantitative imaging outcomes at baseline. They performed ANCOVA testing using 48-month semiquantitative imaging outcomes as dependent variables and confounding variables as covariates.

The researchers analyzed joint space narrowing, KL grade, and tibia/femur medial/lateral compartment osteophyte formation and sclerosis.

At 4 years, the average KL grade in the CS group was 2.79, it was 2.11 in the HA group,;and it was 2.37 in the control group. Intergroup comparisons showed significant differences in KL grade between CS and HA groups and between CS and control groups. Medial compartment joint space narrowing was 1.56 in the CS group, 1.11 in the HA group, and 1.18 in controls. There was a significant difference between the CS and control groups. Other dependent variables were not significant.

“These preliminary results suggest that corticosteroid injections accelerated the radiographic progression of osteoarthritis, specifically medial joint space narrowing and Kellgren-Lawrence grading, whereas hyaluronic acid injections did not,” Mr. Darbandi said in an interview.

“OA radiographic progression does not always correlate with clinical progression, and further research is needed,” he added.

Proper matching of patients at baseline for confounding factors is a strength of the study, Mr. Darbandi said, while the retrospective study design is a weakness.
 

Experts share their perspectives on the preliminary results

Michael M. Kheir, MD, assistant professor of orthopedic surgery at the University of Michigan Health System, who was not involved in the studies, said he would like to see further related research.

“Perhaps steroid injections are not as benign as they once seemed,” he added. “They should be reserved for patients who already have significant arthritis and are seeking temporary relief prior to surgical reconstruction with a joint replacement, or for patients with recalcitrant pain after having already tried HA injections.”

William A. Jiranek, MD, professor and orthopedic surgeon at Duke Health in Morrisville, N.C., who also was not involved in the studies, was not surprised by the findings.

“It is important to do these studies to learn that steroid injections do not come with zero cost,” he said.

“I am pretty sure that a percentage of these patients had no cartilage loss at all,” he added. “We need to understand which OA phenotypes are not at risk of progressive cartilage loss from steroid injections.”

Annunziato (Ned) Amendola, MD, professor and sports medicine orthopedic surgeon at Duke Health in Durham, N.C., who was also not involved in the studies, said he would like to know how injection effectiveness and activity level are related.

“If the injections were effective at relieving pain, and the patients were more active, that may have predisposed to more joint wear,” he said. “It’s like tires that last longer if you don’t abuse them.”
 

Shared decision-making and further research recommended

Amanda E. Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.

“The causal relationship remains in question, and questions around the efficacy of intra-articular HA in particular, and the ideal settings for intra-articular therapy in general, persist,” noted Dr. Nelson, who was also not involved in the studies. “Thus, shared decision-making between patients and their providers is essential when considering these options.”

C. Kent Kwoh, MD, professor of medicine and medical imaging at the University of Arizona and director of the University of Arizona Arthritis Center, both in Tucson, said in an interview that these types of studies are important because CS injections are common treatments for knee OA, they are recommended in treatment guidelines, and other good options are lacking.

But he pointed out that the results of these two studies need to be interpreted with caution and should not be used to decide the course of treatment.

“These data are hypothesis generating. They suggest association, but they do not show causation,” said Dr. Kwoh, who was also not involved in the studies. “Both studies are secondary analyses of data collected from the OAI, which was not specifically designed to answer the questions these studies are posing.

“The OAI was not a treatment study, and participants were seen only once a year or so. They may have had joint injections anytime from only days to around 1 year before their visit, and their levels of activity or pain just prior to or just after their joint injections were not reported,” Dr. Kwoh explained.

The reasons why patients did or did not receive a specific joint injection – including their socioeconomic status, race, access to insurance, and other confounding factors – were not assessed and may have affected the results, he added.

The fact that both studies used the same data and came to the same conclusions gives the conclusions some strength, he said, but “the gold standard to understanding causation would be a randomized, controlled trial.”

Mr. Darbandi’s research received grant support from Boeing, His c-authors, as well as all experts not involved in the studies, reported no relevant financial relationshiips. Dr. Bharadwaj did not provide conflict-of-interest and funding details. Dr. Kwoh reported membership on panels that have developed guidelines for the management of knee OA.

Corticosteroid (CS) injections may worsen progression of knee osteoarthritis as seen on radiography and whole-knee MRI. Injecting hyaluronic acid (HA) instead, or managing the condition without injections, may better preserve knee structure and cartilage, according to results of two related studies presented at the annual meeting of the Radiological Society of North America.

The findings come nonrandomized, observational cohort studies, leading knee OA experts to call for further study in randomized trial settings. In the meantime, shared decision-making between patients and clinicians is advised on the use of these injections.

For knee OA, most patients seek a noninvasive treatment for symptomatic relief. “At least 10% of these patients undergo local treatment with injectable corticosteroids or hyaluronic acid,” the lead author of one of the studies, Upasana Upadhyay Bharadwaj, MD, research fellow in musculoskeletal radiology at the University of California, San Francisco, said in a video press release.

Researchers in both studies used data and images from the Osteoarthritis Initiative (OAI), a multicenter, longitudinal, observational study of 4,796 U.S. patients aged 45-79 years with knee OA. Participants were enrolled from February 2004 to May 2006.

The OAI maintains a natural history database of information regarding participants’ clinical evaluation data, x-rays, MRI scans, and a biospecimen repository. Data are available to researchers worldwide.
 

Two studies draw similar conclusions

In one study, Dr. Bharadwaj and colleagues found that HA injections appeared to show decreased knee OA progression in bone marrow lesions.

They investigated 8 patients who received one CS injection, 12 who received one HA injection, and 40 control persons who received neither treatment. Participants were propensity-score matched by age, sex, body mass index (BMI), Kellgren-Lawrence (KL) grade, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Physical Activity Scale for the Elderly (PASE).

The researchers semiquantitatively graded three Tesla MRI scans that had been obtained at baseline, 2 years before the injection, and 2 years after the injection, using whole-organ MRI score (WORMS) for the meniscus, bone marrow lesions, cartilage, joint effusion, and ligaments.

They quantified OA progression using the difference in WORMS between baseline and 2-year follow-up, and they used linear regression models, adjusted for age, sex, BMI, KL grade, WOMAC, and PASE, to identify the link between type of injection and progression of WORMS.

At 2 years, the authors found a significant association between CS injection and postinjection progression of WORMS over 2 years for the knee overall, the lateral meniscus, lateral cartilage, and medial cartilage. There was no significant link between HA injection and postinjection progression of WORMS or between either injection type and progression of pain, as quantified by WOMAC. There was also no significant difference in progression of WORMS over the 2 years prior to injection for CS and HA injections.

“Corticosteroid injections must be administered with caution with respect to long-term effects on osteoarthritis,” Dr. Bharadwaj advised. “Hyaluronic acid injections, on the other hand, may slow down progression of knee osteoarthritis and alleviate long-term effects while offering similar symptomatic relief to corticosteroid injections. Overall, they are perhaps a safer alternative when looking at medium- and long-term disease course of knee osteoarthritis.”

In the second study, lead author Azad Darbandi, MS, a fourth-year medical student at Chicago Medical School, North Chicago, and colleagues found that patients who received CS injections experienced significantly more medial joint space narrowing.

They identified 210 knees with imaging at baseline and at 48 months that received CS injections, and 59 that received HA injections; 6,827 knees served as controls. The investigators matched 50 patients per group on the basis of confounding factors, which included age, sex, BMI, comorbidities, surgery, and semiquantitative imaging outcomes at baseline. They performed ANCOVA testing using 48-month semiquantitative imaging outcomes as dependent variables and confounding variables as covariates.

The researchers analyzed joint space narrowing, KL grade, and tibia/femur medial/lateral compartment osteophyte formation and sclerosis.

At 4 years, the average KL grade in the CS group was 2.79, it was 2.11 in the HA group,;and it was 2.37 in the control group. Intergroup comparisons showed significant differences in KL grade between CS and HA groups and between CS and control groups. Medial compartment joint space narrowing was 1.56 in the CS group, 1.11 in the HA group, and 1.18 in controls. There was a significant difference between the CS and control groups. Other dependent variables were not significant.

“These preliminary results suggest that corticosteroid injections accelerated the radiographic progression of osteoarthritis, specifically medial joint space narrowing and Kellgren-Lawrence grading, whereas hyaluronic acid injections did not,” Mr. Darbandi said in an interview.

“OA radiographic progression does not always correlate with clinical progression, and further research is needed,” he added.

Proper matching of patients at baseline for confounding factors is a strength of the study, Mr. Darbandi said, while the retrospective study design is a weakness.
 

Experts share their perspectives on the preliminary results

Michael M. Kheir, MD, assistant professor of orthopedic surgery at the University of Michigan Health System, who was not involved in the studies, said he would like to see further related research.

“Perhaps steroid injections are not as benign as they once seemed,” he added. “They should be reserved for patients who already have significant arthritis and are seeking temporary relief prior to surgical reconstruction with a joint replacement, or for patients with recalcitrant pain after having already tried HA injections.”

William A. Jiranek, MD, professor and orthopedic surgeon at Duke Health in Morrisville, N.C., who also was not involved in the studies, was not surprised by the findings.

“It is important to do these studies to learn that steroid injections do not come with zero cost,” he said.

“I am pretty sure that a percentage of these patients had no cartilage loss at all,” he added. “We need to understand which OA phenotypes are not at risk of progressive cartilage loss from steroid injections.”

Annunziato (Ned) Amendola, MD, professor and sports medicine orthopedic surgeon at Duke Health in Durham, N.C., who was also not involved in the studies, said he would like to know how injection effectiveness and activity level are related.

“If the injections were effective at relieving pain, and the patients were more active, that may have predisposed to more joint wear,” he said. “It’s like tires that last longer if you don’t abuse them.”
 

Shared decision-making and further research recommended

Amanda E. Nelson, MD, associate professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina at Chapel Hill, said: “The lack of randomization introduces potential biases around why certain therapies (CS injection, HA injection, or neither) were selected over others (such as disease severity, preference, comorbid conditions, other contraindications, etc), thus making interpretation of the findings challenging.

Tixagevimab copackaged with cilgavimab (Evusheld) is a safe and effective preexposure prophylaxis (PrEP) in patients undergoing B-cell-depleting therapies who have poor immune response to COVID-19 vaccination and are at high risk for serious COVID-19 illness, a small, single-site study suggests.

Evusheld, the only COVID-19 PrEP option available, has Emergency Use Authorization (EUA) from the Food and Drug Administration for treatment of immunocompromised patients who may not respond sufficiently to COVID-19 vaccination and patients who’ve had a severe adverse reaction to COVID-19 vaccination.

“We report the largest real-world experience of Evusheld in this population, and our findings are encouraging,” lead study author Cassandra Calabrese, DO, rheumatologist and infectious disease specialist at Cleveland Clinic, said in an interview.

“Of 412 patients who received Evusheld, 12 [2.9%] developed breakthrough COVID-19, with 11 having mild courses and 1 who required hospitalization but recovered,” she added.

“Our data suggest that Evusheld PrEP, in combination with aggressive outpatient treatment of COVID-19, is likely effective in lowering risk of severe COVID in this vulnerable group.

“Practitioners who care for patients with immune-mediated inflammatory diseases should triage high-risk patients for Evusheld as well as rapid diagnosis and aggressive outpatient therapy if infected,” Dr. Calabrese advised.

For the study, Dr. Calabrese and colleagues at Cleveland Clinic searched the health care system pharmacy records for patients with immune‐mediated inflammatory diseases (IMIDs) or inborn errors of humoral immunity (IEI) who met the criteria to receive Evusheld. The researchers included patients on B-cell-depleting therapies or with humoral IEI who had received at least one dose of Evusheld and were later diagnosed with COVID-19, and they excluded those treated with B-cell-depleting therapies for cancer.
 

EVUSHELD was well tolerated

After extracting data on COVID-19 infection, vaccination status, and outcomes, they found that, between Jan. 18 and May 28, 2022, 412 patients with IMIDs or humoral IEI received Evusheld. No deaths occurred among these patients and, overall, they tolerated the medication well.

All 12 patients who experienced breakthrough COVID-19 infection were treated with B-cell-depleting therapies. Among the 12 patients:

• Six patients developed infection 13-84 (median 19) days after receiving 150 mg/150 mg tixagevimab/cilgavimab.
• Six patients developed infection 19-72 (median of 38.5) days after either a single dose of 300 mg/300 mg or a second dose of 150 mg/150 mg.
• Eleven patients had mild illness and recovered at home; one patient was hospitalized and treated with high-flow oxygen. All cases had been vaccinated against COVID-19 (five received two vaccinations, six received three, and one received four).
• One possible serious adverse event involved a patient with COVID-19 and immune-mediated thrombocytopenia (ITP) who was hospitalized soon after receiving Evusheld with ITP flare that resolved with intravenous immunoglobulin.

Dr. Calabrese acknowledged limitations to the study, including few patients, lack of a comparator group, and the study period falling during the Omicron wave.

“Also, nine of the breakthrough cases received additional COVID-19 therapy (oral antiviral or monoclonal antibody), which falls within standard of care for this high-risk group but prevents ascribing effectiveness to individual components of the regimen,” she added.

“Evusheld is authorized for PrEP against COVID-19 in patients at high risk for severe COVID due to suboptimal vaccine responses. This includes patients receiving B-cell-depleting drugs like rituximab, and patients with inborn errors of humoral immunity,” Dr. Calabrese explained.

“It is well known that this group of patients is at very high risk for severe COVID and death, even when fully vaccinated, and it has become clear that more strategies are needed to protect this vulnerable group, including use of Evusheld as well as aggressive treatment if infected,” she added.  
 

Evusheld not always easy to obtain

Although the medication has been available in the United States since January 2022, Dr. Calabrese said, patients may not receive it because of barriers including lack of both awareness and access.

Davey Smith, MD, professor of medicine and head of infectious diseases and global public health at the University of California San Diego, in La Jolla, said in an interview that he was not surprised by the results, but added that the study was conducted in too few patients to draw any strong conclusions or affect patient care.

“This small study that showed that breakthrough infections occurred but were generally mild, provides a small glimpse of real-world use of tixagevimab/cilgavimab as PrEP for immunocompromised persons,” said Dr. Smith, who was not involved in the study.

“In the setting of Omicron and vaccination, I would expect the same outcomes reported even without the treatment,” he added.

Dr. Smith recommends larger related randomized, controlled trials to provide clinicians with sufficient data to guide them in their patient care.

Graham Snyder, MD, associate professor in the division of infectious diseases at the University of Pittsburgh and medical director of infection prevention and hospital epidemiology at the University of Pittsburgh Medical Center, noted that the study “adds to a quickly growing literature on the real-world benefits of tixagevimab/cilgavimab to protect vulnerable individuals with weakened immune systems from the complications of COVID-19.

“This study provides a modest addition to our understanding of the role and benefit of Evusheld,” Dr. Snyder said in an interview. “By characterizing only patients who have received Evusheld without an untreated comparison group, we can’t draw any inference about the extent of benefit the agent provided to these patients.

“Substantial data already show that this agent is effective in preventing complications of COVID-19 infection in immunocompromised individuals,” added Dr. Snyder, who was not involved in the study.

“ ‘Immunocompromised’ represents a very diverse set of clinical conditions,” he said. “The research agenda should therefore focus on a more refined description of the effect in specific populations and a continued understanding of the effect of Evusheld in the context of updated vaccination strategies and changing virus ecology.”

Dr. Calabrese and her colleagues wrote that larger, controlled trials are underway.

 

FDA: Evusheld may not neutralize certain SARS-CoV-2 variants

“The biggest unanswered question is how Evusheld will hold up against new variants,” Dr. Calabrese said.

In an Oct. 3, 2022, update, the Food and Drug Administration released a statement about the risk of developing COVID-19 from SARS-CoV-2 variants that are not neutralized by Evusheld. The statement mentions an updated fact sheet that describes reduced protection from Evusheld against the Omicron subvariant BA.4.6, which accounted for nearly 13% of all new COVID-19 cases in the United States in the week ending Oct. 1.

There was no outside funding for the study. Dr. Smith reported no relevant financial conflicts of interest. Dr. Snyder said he is an unpaid adviser to an AstraZeneca observational study that’s assessing the real-world effectiveness of Evusheld.

Evusheld, the only COVID-19 PrEP option available, has Emergency Use Authorization (EUA) from the Food and Drug Administration for treatment of immunocompromised patients who may not respond sufficiently to COVID-19 vaccination and patients who’ve had a severe adverse reaction to COVID-19 vaccination.

“We report the largest real-world experience of Evusheld in this population, and our findings are encouraging,” lead study author Cassandra Calabrese, DO, rheumatologist and infectious disease specialist at Cleveland Clinic, said in an interview.

“Of 412 patients who received Evusheld, 12 [2.9%] developed breakthrough COVID-19, with 11 having mild courses and 1 who required hospitalization but recovered,” she added.

“Our data suggest that Evusheld PrEP, in combination with aggressive outpatient treatment of COVID-19, is likely effective in lowering risk of severe COVID in this vulnerable group.

“Practitioners who care for patients with immune-mediated inflammatory diseases should triage high-risk patients for Evusheld as well as rapid diagnosis and aggressive outpatient therapy if infected,” Dr. Calabrese advised.

For the study, Dr. Calabrese and colleagues at Cleveland Clinic searched the health care system pharmacy records for patients with immune‐mediated inflammatory diseases (IMIDs) or inborn errors of humoral immunity (IEI) who met the criteria to receive Evusheld. The researchers included patients on B-cell-depleting therapies or with humoral IEI who had received at least one dose of Evusheld and were later diagnosed with COVID-19, and they excluded those treated with B-cell-depleting therapies for cancer.
 

EVUSHELD was well tolerated

After extracting data on COVID-19 infection, vaccination status, and outcomes, they found that, between Jan. 18 and May 28, 2022, 412 patients with IMIDs or humoral IEI received Evusheld. No deaths occurred among these patients and, overall, they tolerated the medication well.

All 12 patients who experienced breakthrough COVID-19 infection were treated with B-cell-depleting therapies. Among the 12 patients:

• Six patients developed infection 13-84 (median 19) days after receiving 150 mg/150 mg tixagevimab/cilgavimab.
• Six patients developed infection 19-72 (median of 38.5) days after either a single dose of 300 mg/300 mg or a second dose of 150 mg/150 mg.
• Eleven patients had mild illness and recovered at home; one patient was hospitalized and treated with high-flow oxygen. All cases had been vaccinated against COVID-19 (five received two vaccinations, six received three, and one received four).
• One possible serious adverse event involved a patient with COVID-19 and immune-mediated thrombocytopenia (ITP) who was hospitalized soon after receiving Evusheld with ITP flare that resolved with intravenous immunoglobulin.

Dr. Calabrese acknowledged limitations to the study, including few patients, lack of a comparator group, and the study period falling during the Omicron wave.

“Also, nine of the breakthrough cases received additional COVID-19 therapy (oral antiviral or monoclonal antibody), which falls within standard of care for this high-risk group but prevents ascribing effectiveness to individual components of the regimen,” she added.

“Evusheld is authorized for PrEP against COVID-19 in patients at high risk for severe COVID due to suboptimal vaccine responses. This includes patients receiving B-cell-depleting drugs like rituximab, and patients with inborn errors of humoral immunity,” Dr. Calabrese explained.

“It is well known that this group of patients is at very high risk for severe COVID and death, even when fully vaccinated, and it has become clear that more strategies are needed to protect this vulnerable group, including use of Evusheld as well as aggressive treatment if infected,” she added.  
 

Evusheld not always easy to obtain

Although the medication has been available in the United States since January 2022, Dr. Calabrese said, patients may not receive it because of barriers including lack of both awareness and access.

Davey Smith, MD, professor of medicine and head of infectious diseases and global public health at the University of California San Diego, in La Jolla, said in an interview that he was not surprised by the results, but added that the study was conducted in too few patients to draw any strong conclusions or affect patient care.

“This small study that showed that breakthrough infections occurred but were generally mild, provides a small glimpse of real-world use of tixagevimab/cilgavimab as PrEP for immunocompromised persons,” said Dr. Smith, who was not involved in the study.

“In the setting of Omicron and vaccination, I would expect the same outcomes reported even without the treatment,” he added.

Dr. Smith recommends larger related randomized, controlled trials to provide clinicians with sufficient data to guide them in their patient care.

Graham Snyder, MD, associate professor in the division of infectious diseases at the University of Pittsburgh and medical director of infection prevention and hospital epidemiology at the University of Pittsburgh Medical Center, noted that the study “adds to a quickly growing literature on the real-world benefits of tixagevimab/cilgavimab to protect vulnerable individuals with weakened immune systems from the complications of COVID-19.

“This study provides a modest addition to our understanding of the role and benefit of Evusheld,” Dr. Snyder said in an interview. “By characterizing only patients who have received Evusheld without an untreated comparison group, we can’t draw any inference about the extent of benefit the agent provided to these patients.

“Substantial data already show that this agent is effective in preventing complications of COVID-19 infection in immunocompromised individuals,” added Dr. Snyder, who was not involved in the study.

“ ‘Immunocompromised’ represents a very diverse set of clinical conditions,” he said. “The research agenda should therefore focus on a more refined description of the effect in specific populations and a continued understanding of the effect of Evusheld in the context of updated vaccination strategies and changing virus ecology.”

Dr. Calabrese and her colleagues wrote that larger, controlled trials are underway.

 

FDA: Evusheld may not neutralize certain SARS-CoV-2 variants

“The biggest unanswered question is how Evusheld will hold up against new variants,” Dr. Calabrese said.

In an Oct. 3, 2022, update, the Food and Drug Administration released a statement about the risk of developing COVID-19 from SARS-CoV-2 variants that are not neutralized by Evusheld. The statement mentions an updated fact sheet that describes reduced protection from Evusheld against the Omicron subvariant BA.4.6, which accounted for nearly 13% of all new COVID-19 cases in the United States in the week ending Oct. 1.

There was no outside funding for the study. Dr. Smith reported no relevant financial conflicts of interest. Dr. Snyder said he is an unpaid adviser to an AstraZeneca observational study that’s assessing the real-world effectiveness of Evusheld.

Men who have sex with men (MSM) living with HIV, especially those who are young or who’ve had gonorrhea, should get the human papillomavirus (HPV) 9-valent vaccine (Gardasil 9), findings of a newly published study in the Journal of Acquired Immune Deficiency Syndromes suggest.

According to the World Health Organization, only 30% of the target population worldwide has received the HPV vaccine. Despite increased risk for HPV anal infection (an estimated three out of four MSM develop an anal infection from any HPV genotype in their lifetime, epidemiological studies in MSM have been lacking, leaving gaps in data in terms of prevalence rates and prevention.

To help characterize which MSM subgroups benefit the most from early 9-valent HPV vaccination, researchers from Vita-Salute San Raffaele University in Milan determined the prevalence of anal HPV genotypes in MSM who’d been living with HIV for 5 years, and they analyzed the risk factors for HPV anal infection.

Of the 1,352 study participants, 12% were not infected by any HPV genotypes, and the maximum number of genotypes infecting one person (six) was detected in 0.4% (six) people. The prevalence of HR-HPV genotypes or those present in the vaccine remained stable over time.

“Our findings suggest ... that all MSM with HIV would benefit from Gardasil 9 immunization, particularly the youngest and those with a prior gonococcal infection,” wrote Elena Bruzzesi, MD, of Vita-Salute San Raffaele University, and her coauthors.

To determine prevalence of HPV genotypes at anal sites and risk factors, the authors conducted a time-trend, monocentric study on participants who self-identified as MSM who engaged in anal intercourse. The participants underwent one or more anoscopies for HPV genotyping at one academic hospital in Milan between 2015 and 2019.

Swab specimens were collected from the anal canal mucosa, then soaked in thin-layer liquid medium, and sent for molecular analysis.

For detection of HPV phenotypes, the specimens were processed by multiplex real-time polymerase chain reaction.

Findings showed that:

• The overall prevalence of MSM with at least one anal HPV genotype was 88%, with prevalence ranging from 77% to 84%, and no trend difference over the 5-year period.
• Seventy-nine percent of participants were exposed to at least one high-risk (HR)-HPV genotype, and 67.4% by at least one low-risk (LR)-HPV genotype.
• HPV-53, in 27%, was the most prevalent genotype. HPV-6, 11, 16, and 18 prevalence was 22%, 13%, 23%, and 11%, respectively. Of the HR genotypes, HPV-16 and HPV-18 are most often linked with squamous cell cancers and adenocarcinomas, and in the study, prevalence did not change over time.
• Seventy-one percent of participants carried at least one genotype covered by the vaccine, with no change over time.
• On multivariable analysis, the risk of carrying at least one high-risk HPV genotype was linked with younger age (adjusted odds ratio [aOR] for 30 years or younger compared with older than 45 years 2.714; 95% confidence interval [CI], 1.484-4.961), and with having had gonorrhea (aOR, 2.118; 95% CI, 1.100-4.078).
• Also on multivariable analysis, the risk of having one or more genotypes targeted by the 9-valent vaccine was linked with younger age (aOR, 1.868; 95% CI, 1.141-3.060) and with having had gonorrhea (aOR, 1.785; 95% CI, 1.056-3.018).

“We are underutilizing the HPV vaccine in our clinical settings in the United States and globally,” Mehri S. McKellar, MD, an infectious disease specialist at Duke Health in Durham, N.C., told this news organization.

“This powerful study provides important data on HPV genotype prevalence in the MSM HIV+ population, validating that Gardasil 9 will greatly help these individuals,” said Dr. McKellar, who was not involved in the study.

Robert Salata, MD, infectious disease specialist and professor at Case Western Reserve University, Cleveland, also encourages MSM to get the vaccine.

“It is important to understand that the prevalence of anal HPV in men who have sex with men is very high, that the prevalence, including high-risk genotypes, has remained stable, and that the 9-valent vaccine is clearly indicated, especially in younger men and those with known gonorrhea and other STDs,” Dr. Salata (who was also not involved in the study) told this news organization.

“This is an important reminder for us to continue promoting and providing the vaccine to our patients, especially to HIV+ men who have sex with men, who have the highest rates of anal infection with HPV,” Dr. McKellar advised.

The authors, Dr. McKellar, and Dr. Salata report no relevant financial relationships.

French children with peanut allergy tend to have reactions to other legumes, including soy, lentil, pea, bean, lupin, and fenugreek, and those other allergies often lead to anaphylactic reactions, a retrospective study from France reports.

“Among children allergic to peanut, at least two-thirds were sensitized to one other legume, and legume allergy was diagnosed in one-quarter of the sensitized patients,” wrote senior study author Amandine Divaret-Chauveau, MD, of Centre Hospitalier Universitaire de Nancy, Vandoeuvre-les-Nancy, and colleagues. The report is in Pediatric Allergy and Immunology.

People worldwide are eating more legumes these days, the authors noted. High in protein, low in unsaturated fats, with low production costs, legumes are important components of increasingly vegetarian, healthy, sustainable diets.

Food allergens are the most common childhood triggers of allergic reactions. Among children in France, legumes cause 14.6% of food-related anaphylactic reactions, with peanut as the main allergen, they added.

Dr. Divaret-Chauveau and colleagues assessed the prevalence and relevance of sensitization to legumes among all children and adolescents aged 1-17 years who had peanut allergy and had been admitted to one academic pediatric allergy department over roughly 3 years, beginning in early 2017. For the 195 study participants, peanut allergy had been confirmed, and they had been documented to have consumed or to have sensitization to at least one non-peanut legume; 69.7% were boys.

The researchers analyzed data on consumption history, skin prick tests, specific immunoglobulin E status, prior allergic reactions, and oral food challenges for each legume. They found the following:

• Among the 195 children with peanut allergy, 98.4% had at least one other atopic disease.
• Of the 195 children with peanut allergy, 122 (63.9%) were sensitized to at least one other legume. Of these 122 children, 66.3% were sensitized to fenugreek, 42.2% to lentil, 39.9% to soy, and 34.2% to lupin.
• Allergy to one or more legumes was confirmed for 27.9% of the 122 sensitized children, including 4.9% who had multiple legume allergies. Lentil, lupin, and pea were the main allergens.
• Of the 118 children also having a non-legume food allergy, the main food allergens were egg (57.6%), cow’s milk (33.0%), cashew (39.0%), pistachio (23.7%), and hazelnut (30.5%).
• Fifty percent of allergic reactions to non-peanut legumes were severe, often showing as asthma. Atopic comorbidities, including asthma, in most participants may have contributed to the severity of allergic reactions, the authors noted.

Allergy awareness needs to grow with plant-based diets

“The high prevalence of legume sensitization reported in our study highlights the need to explore legume consumption in children with PA [peanut allergy], and the need to investigate sensitization in the absence of consumption,” they added.

Jodi A. Shroba, MSN, APRN, CPNP, coordinator for the Food Allergy Program at Children’s Mercy Kansas City, in Missouri, told this news organization that few data are available in the literature regarding allergies to legumes other than peanut.

“It was interesting that these authors found such a high legume sensitization in their peanut-allergic patients,” Ms. Shroba, who was not involved in the study, said by email. “As more people are starting to eat plant-based diets, it is important that we better understand their allergenicity and cross-reactivity so we can better help guide patient management and education.”

Deborah Albright, MD, assistant professor of pediatrics at the University of Pittsburgh, agreed.

“As plant-based protein consumption broadens worldwide, awareness of the potential for cross-reactivity and co-allergy amongst legumes will become increasingly important,” she said by email.

“However, positive allergy tests do not reliably correlate with true food allergy; therefore, the diagnosis of legume co-allergy should be confirmed by the individual patient’s history, a formal food challenge, or both,” advised Dr. Albright. She was not involved in the study.

“Cross-sensitization to other legumes in patients with a single legume allergy is common; however, true clinical reactivity is often not present,” she added. “Also, legume allergy test sensitization rates and objective reactivity on food challenge can vary by region, depending on diet and pollen aeroallergen exposure.

“Systematic exploration of tolerance versus co-allergy to other legumes should be considered in patients allergic to peanut or other legumes,” Dr. Albright said.

The authors recommend further research and registry data collection of legume anaphylaxis.

Details regarding funding for the study were not provided. The authors, Ms. Shroba, and Dr. Albright report no relevant financial relationships.

Jodi A. Shroba, MSN, APRN, CPNP, coordinator for the Food Allergy Program at Children’s Mercy Kansas City, in Missouri, told this news organization that few data are available in the literature regarding allergies to legumes other than peanut.

“It was interesting that these authors found such a high legume sensitization in their peanut-allergic patients,” Ms. Shroba, who was not involved in the study, said by email. “As more people are starting to eat plant-based diets, it is important that we better understand their allergenicity and cross-reactivity so we can better help guide patient management and education.”

Deborah Albright, MD, assistant professor of pediatrics at the University of Pittsburgh, agreed.

“As plant-based protein consumption broadens worldwide, awareness of the potential for cross-reactivity and co-allergy amongst legumes will become increasingly important,” she said by email.

“However, positive allergy tests do not reliably correlate with true food allergy; therefore, the diagnosis of legume co-allergy should be confirmed by the individual patient’s history, a formal food challenge, or both,” advised Dr. Albright. She was not involved in the study.

“Cross-sensitization to other legumes in patients with a single legume allergy is common; however, true clinical reactivity is often not present,” she added. “Also, legume allergy test sensitization rates and objective reactivity on food challenge can vary by region, depending on diet and pollen aeroallergen exposure.

“Systematic exploration of tolerance versus co-allergy to other legumes should be considered in patients allergic to peanut or other legumes,” Dr. Albright said.

The authors recommend further research and registry data collection of legume anaphylaxis.

Details regarding funding for the study were not provided. The authors, Ms. Shroba, and Dr. Albright report no relevant financial relationships.

All atopic diseases, as well as environmental and parental factors, appear to be linked with hand eczema (HE), a longitudinal study from Finland has shown.

“In this population-based study, all atopic diseases, not only atopic dermatitis, were found as individual risk factors for HE. In addition, female gender, obesity and mold exposure increased the risk of HE,” wrote Marjut Koskelo, MD, and her colleagues at the University of Oulu in Finland. Their report was published in Contact Dermatitis.

“Parental allergy was also a risk factor of offspring’s HE. Moderate or high physical activity as well as owning a dog appeared as protective factors of HE. No association was found between other lifestyle factors and HE,” they added.

Hand eczema is one of the most common skin disorders and is the most common occupational skin disease, the authors wrote. Many risk factors, including atopic dermatitis, are known to be linked with HE, but whether various other factors might also be linked has not been well studied.

The research team investigated the link between HE and atopic diseases, parental factors, environmental factors (exposure to mold, keeping animals), and lifestyle factors (physical activity, obesity, tobacco and alcohol use).

They analyzed data of people who took part in the Northern Finland Birth Cohort 1966 Study. The data, collected since 1965, includes details about 12,055 mothers in northern Finland who were expected to deliver babies in 1966, and their 12,058 live-born children. The children have been followed over the years with questionnaires and clinical examinations, and their parents have been followed by national registers and medical reports.

For the 46-year follow-up, 6,830 respondents aged 45-46 years, roughly half of them women, completed a 132-question form covering physical health, lifestyle, environmental factors, socioeconomic status, and history of hand eczema and other atopic diseases.

In the statistical analysis, the researchers adjusted for atopic dermatitis, asthma, allergic rhinoconjunctivitis, education level, body mass index, maternal BMI, parental allergy, physical activity, living on a farm, and mold exposure and symptoms.

Of the 900 respondents who reported having had HE, 592 (65.8%) were women and 308 (34.2%) were men (odds ratio [OR], 1.73; 95% confidence interval [CI], 1.49-2.0).
 

Various factors linked with hand eczema risk

The authors found the following:

• Atopic diseases and HE were linked: atopic dermatitis (adjusted odds ratio [aOR], 9.66; 95% CI, 8.03-11.66), asthma (aOR, 1.38; 95% CI, 1.12-1.71), and allergic rhinoconjunctivitis (aOR, 1.28; 95% CI, 1.04-1.56). Sex did not affect the link between atopic diseases and HE.
• Respondents who reported visible mold or mold odor in their apartments had higher risk for HE than did those without a history of mold exposure (OR, 1.32; 95% CI, 1.07-1.61).
• Obesity was linked with HE (OR, 3.44; 95% CI, 1.05-22.8), but smoking status, alcohol intake, and education level were not statistically significant risk factors for HE.
• Participants who reported moderate or high physical activity had lower risk for HE (OR, 0.78; 95% CI, 0.64-0.94; and OR, 0.56; 95% CI, 0.33-0.91, respectively) than those who were less active.
• Parental allergy increased risk for HE (OR, 1.98; 95% CI, 1.70-2.30); as maternal age, BMI, and menarche age increased, so did the risk for the child’s HE, but the increases were not statistically significant; and no significant links were found between maternal tobacco smoking, parental asthma, birth weight, parity, gestational age, and HE.
• Dog owners had less risk for HE than did people without a dog (OR, 0.83; 95% CI, 0.71-0.97); links between cat or farm animal owners and HE were not significant.

“There is a strong association between hand eczema and atopic diseases,” Maya Jonas, MD, clinical assistant professor of dermatology at The Ohio State University Wexner Medical Center in Columbus, told this news organization.

“When evaluating patients with hand eczema, it is important to ask if they have a history of atopic dermatitis, asthma, or allergic rhinitis,” said Dr. Jonas, who was not involved in the study.

Elma Baron, MD, professor and director, Skin Study Center, department of dermatology, Case Western Reserve University, Cleveland, was surprised by the inverse link between physical activity and HE. 

“What struck me as interesting is the inverse association between hand eczema and physical activity, that greater physical activity will decrease the risk for hand eczema,” she said in an interview. “It’s an interesting finding that’s worth exploring.

“Dermatologists have also speculated about the association with the female gender, because women are more likely to be in situations that involve frequent hand washing or in occupations, such as hairdressing, that involve known irritants and allergens,” added Dr. Baron, who was not involved in the study.

The main weakness, she noted, is the reliance on self-reported diagnosis. “Hand eczema is a common condition, but the etiologies of reported hand eczema may vary.

“Being cognizant of these associations can help us prescribe appropriate medications and advise patients about how they can avoid exposures that will aggravate their condition,” Dr. Baron advised.

The authors recommend further related studies.

The authors, Dr. Jonas, and Dr. Baron report no relevant financial relationships. The study was not funded.

Managing children’s cow’s milk allergy is costly to families and to health care systems, largely owing to costs of prescriptions, according to an industry-sponsored study based on data from the United Kingdom.

“This large cohort study provides novel evidence of a significant health economic burden of cow’s milk allergy in children,” Abbie L. Cawood, PhD, RNutr, MICR, head of scientific affairs at Nutricia Ltd in Trowbridge, England, and colleagues wrote in Clinical and Translational Allergy.

“Management of cow’s milk allergy necessitates the exclusion of cow’s milk protein from the diet. Whilst breastmilk remains the ideal nutrient source in infants with cow’s milk allergy, infants who are not exclusively breastfed require a hypoallergenic formula,” added Dr. Cawood, a visiting research fellow at University of Southampton, and her coauthors.

Cow’s milk allergy, an immune‐mediated response to one or more proteins in cow’s milk, is one of the most common childhood food allergies and affects 2%-5% of infants in Europe. Management involves avoiding cow’s milk protein and treating possible related gastrointestinal, skin, respiratory, and other allergic conditions, the authors explained.

In their retrospective matched cohort study, Dr. Cawood and colleagues turned to The Health Improvement Network (THIN), a Cegedim Rx proprietary database of 2.9 million anonymized active patient records. They extracted data from nearly 7,000 case records covering 5 years (2015-2020).

They examined medication prescriptions and health care professional contacts based on diagnosis read-codes and hypoallergenic formula prescriptions and compared health care costs for children with cow’s milk allergy with the costs for those without.

They matched 3,499 children aged 1 year or younger who had confirmed or suspected cow’s milk allergy with the same number of children without cow’s milk allergy. Around half of the participants were boys, and the mean observation period was 4.2 years.
 

Children with cow’s milk allergy need more, costly health care

The researchers found:

• Medications were prescribed to significantly more children with cow’s milk allergy (CMA), at a higher rate, than to those without CMA. In particular, prescriptions for antireflux medication increased by almost 500%.
• Children with CMA needed significantly more health care contacts and at a higher rate than those without CMA.
• CMA was linked with additional potential health care costs of £1381.53 per person per year. Assuming a 2.5% prevalence from the estimated 2%-5% CMA prevalence range and extrapolating to the UK infant population, CMA may have added more than £25.7 million in annual health care costs nationwide.

“Several conditions in infancy necessitate the elimination of cow milk–based formulas and require extensively hydrolyzed or amino acid formulas or, if preferred or able, exclusive breast milk,” Kara E. Coffey, MD, assistant professor of pediatrics at the University of Pittsburgh, said by email.

“This study shows that, regardless of the reason for cow milk–based avoidance, these infants require more healthcare service utilizations (clinic visits, nutritional assessments, prescriptions) than [do] their peers, which is certainly a commitment of a lot of time and money for their families to ensure their ability to grow and thrive,” added Dr. Coffey, who was not involved in the study.

Jodi A. Shroba, MSN, APRN, CPNP, the coordinator for the Food Allergy Program at Children’s Mercy Kansas City, Mo., did not find these numbers surprising.

“Children with food allergies typically have other atopic comorbidities that require more visits to primary care physicians and specialists and more prescriptions,” Ms. Shroba, who was not involved in the study, said by email.

“An intriguing statement is that the U.K. guidelines recommend the involvement of a dietitian for children with cow’s milk allergy,” she noted. “In the United States, having a dietitian involved would be a wonderful addition to care, as avoidance of cow’s milk can cause nutritional and growth deficiencies. But not all healthcare practices have those resources available.

“The higher rate of antibiotic use and the almost 500% increase of antireflux prescriptions by the children with cow’s milk allergy warrant additional research,” she added.

Nutricia Ltd. funded the study. Dr. Cawood and one coauthor are employed by Nutricia, and all other coauthors have been employees of or have other financial relationships with Nutricia.

In patients with moderate-to-severe atopic dermatitis, abrocitinib showed consistent treatment responses and no new safety issues, whether or not they had already been treated with the biologic dupilumab, an industry-sponsored study reports.

“In this post hoc analysis, both the efficacy and the safety profiles of abrocitinib were consistent in patients with moderate-to-severe atopic dermatitis, regardless of prior biologic therapy use,” lead author Melinda Gooderham, MD, medical director of the SKiN Centre for Dermatology, Peterborough, Ont., said during an oral presentation at the Society for Investigative Dermatology (SID) 2022 Annual Meeting.

“These results ... support the use of abrocitinib in patients who might have received biologic therapy prior,” she added.

“Prior biologic use did not reveal any new safety signals ... keeping in mind the key limitation of this analysis is that it was done post hoc,” she noted.

Guidelines for moderate-to-severe atopic dermatitis refractory to topical or systemic therapy include systemic immunosuppressants and dupilumab, a monoclonal antibody that inhibits interleukin-4 and interleukin-13 cytokine-induced responses, Dr. Gooderham said.

The Food and Drug Administration recently approved abrocitinib, an oral once-a-day Janus kinase 1 (JAK1) inhibitor, to treat the disease. The approval came with a boxed warning about increased risk for serious infections, mortality, malignancy, and lymphoproliferative disorders, major adverse cardiovascular events, thrombosis, and laboratory abnormalities.

Dr. Gooderham and colleagues investigated whether patients who’d been treated with a biologic would respond to abrocitinib differently than patients who had not received prior biologic treatment.

Researchers pooled data from two phase 3 placebo-controlled trials of abrocitinib that led to approval and an earlier phase 2b study. They identified 67 patients previously treated with dupilumab and 867 patients who were bio-naive. They repeated their analysis using data from another phase 3 study of abrocitinib on 86 patients previously treated with dupilumab and 1,147 who were bio-naive. On average, the bio-experienced patients were in their mid-30s to early 40s, and the bio-naive group was several years younger.

In the pooled phase 2b and phase 3 JADE MONO-1 and JADE MONO-2 monotherapy trials, patients received once-daily abrocitinib 100 or 200 mg or placebo for 12 weeks. In the phase 3 JADE REGIMEN, which they analyzed separately, eligible patients were enrolled in a 12-week open-label run-in period during which they received an induction treatment of abrocitinib 200 mg once a day.

Researchers compared results of two assessments: the IGA (Investigator Global Assessment) and EASI-75 (Eczema Area and Severity Index, 75% or greater improvement from baseline).

• At week 12, IGA 0/1 dose-dependent response rates were similar in the pooled groups, regardless of whether they had received prior biologic therapy. With abrocitinib 200 mg, 43.5% of those with prior dupilumab therapy responded versus 41.4% of bio-naive patients; with abrocitinib 100 mg, 24.1% versus 26.7% responded. In JADE REGIMEN, corresponding response rates with abrocitinib 200 mg were 53.5% versus 66.9%, respectively.
• At week 12, EASI-75 responses were also comparable. In the pooled groups by dose, with abrocitinib 200 mg, EASI-75 response rates were 65.2% in patients with prior dupilumab therapy versus 62.4% in those without; at abrocitinib 100 mg, 34.5% versus 42.7% responded. Corresponding rates in JADE REGIMEN were 64.0% versus 76.4%, respectively.
• Treatment-emergent adverse event rates among patients with versus without prior biologic therapy were, respectively, 71.7% versus 69.9% (abrocitinib 200 mg + 100 mg groups) in the pooled population. Rates in JADE REGIMEN with abrocitinib 200 mg were, respectively, 66.3% versus 66.5%.
• Abrocitinib efficacy and safety were consistent in patients with moderate-to-severe atopic dermatitis, regardless of prior biologic therapy. Adverse events in the pooled monotherapy trials and in JADE REGIMEN included acne, atopic dermatitis, diarrhea, headache, nasopharyngitis, nausea, upper abdominal pain, and upper respiratory tract infection.

The authors acknowledge that the post hoc study design is a limitation and recommend confirming these findings in a large, long-term prospective study.
 

JAK inhibitors expand treatment options

The results will help doctors treat their patients, Jami L. Miller, MD, associate professor of dermatology and dermatology clinic medical director at Vanderbilt University Medical Center, Nashville, Tenn., told this news organization.

“Because JAK inhibitors have potentially more side effects than inhibitors of interleukin-4 and interleukin-13, in clinical practice most dermatologists are more likely to treat patients first with dupilumab or similar meds and step up to a JAK inhibitor if they do not respond,” she added in an email. 

“With more meds coming out to meet the needs of this population, this is an exciting time for patients with moderate-to-severe atopic dermatitis,” she commented.

Lindsay C. Strowd, MD, associate professor and vice chair of the department of dermatology at Wake Forest University, Winston-Salem, N.C., said JAK inhibitors are increasingly being studied and approved for use in various dermatologic diseases.

An oral JAK inhibitor (upadacitinib) is currently FDA approved for moderate-to-severe atopic dermatitis, and a topical JAK inhibitor (ruxolitinib) is also approved for use in atopic dermatitis, Dr. Strowd noted.

“The study results give providers important practical information,” added Dr. Strowd, who also was not involved with the study. “Those of us who care for patients with severe atopic dermatitis need to know how patients with prior biologic exposure will respond as newer agents come to market and the options for biologic use in atopic dermatitis continue to grow.”

The study was sponsored by Pfizer. All study authors have reported relevant financial relationships with, and several authors are employees of, Pfizer, the developer of abrocitinib. Dr. Strowd and Dr. Miller have reported no relevant financial relationships.

In patients with moderate-to-severe atopic dermatitis, abrocitinib showed consistent treatment responses and no new safety issues, whether or not they had already been treated with the biologic dupilumab, an industry-sponsored study reports.

“In this post hoc analysis, both the efficacy and the safety profiles of abrocitinib were consistent in patients with moderate-to-severe atopic dermatitis, regardless of prior biologic therapy use,” lead author Melinda Gooderham, MD, medical director of the SKiN Centre for Dermatology, Peterborough, Ont., said during an oral presentation at the Society for Investigative Dermatology (SID) 2022 Annual Meeting.

“These results ... support the use of abrocitinib in patients who might have received biologic therapy prior,” she added.

“Prior biologic use did not reveal any new safety signals ... keeping in mind the key limitation of this analysis is that it was done post hoc,” she noted.

Guidelines for moderate-to-severe atopic dermatitis refractory to topical or systemic therapy include systemic immunosuppressants and dupilumab, a monoclonal antibody that inhibits interleukin-4 and interleukin-13 cytokine-induced responses, Dr. Gooderham said.

The Food and Drug Administration recently approved abrocitinib, an oral once-a-day Janus kinase 1 (JAK1) inhibitor, to treat the disease. The approval came with a boxed warning about increased risk for serious infections, mortality, malignancy, and lymphoproliferative disorders, major adverse cardiovascular events, thrombosis, and laboratory abnormalities.

Patients with psoriasis and psoriatic arthritis who belong to underserved groups may not be getting the health care they need because of lack of access, a study based on national registry data suggests.

“Using the All of Us dataset, we identified lower rates of psoriasis and psoriatic arthritis in participants with skin of color, lower education levels, and no health insurance,” lead author Megan M. Tran said in her oral presentation at the annual meeting of the Society for Investigative Dermatology.

“This suggests psoriasis and psoriatic arthritis underdiagnosis in these underserved populations, possibly due to limited dermatologic care access,” added Ms. Tran, a second-year medical student at Brown University in Providence, R.I.

Ms. Tran and colleagues used the ongoing National Institutes of Health All of Us Research Program registry that contains a large proportion of participants from groups in the United States who have historically been underrepresented in biomedical research, she said in her talk. 

Of the 329,038 participants with data in version 5 (released this past March) of the All of Us database, 150,158 (45.6%) had skin of color, and 251,597 (76.5%) had available electronic health records (EHRs).
 

Underserved groups need better access to health care

Linking data from EHRs, surveys, and physical measurements at enrollment, the researchers used several variables to estimate psoriasis and psoriatic arthritis (PsA) prevalence, and they used multivariate logistic regression to adjust for the variables. They found:

• Twenty-two percent of patients with psoriasis had PsA. Odds of psoriasis and PsA were lower among Black (psoriasis odds ratio [OR], 0.32, 95% confidence interval [CI], 0.28-0.36; PsA OR, 0.20, 95% CI, 0.15-0.26) and Hispanic participants (psoriasis OR, 0.77, 95% CI, 0.71-0.84; PsA OR, 0.74, 95% CI, 0.61-0.89) compared with White participants.
• Psoriasis prevalence increased linearly with age (topping off at age 70 and older [OR, 3.35, 95% CI, 2.91-3.88], with 18-29 years as the reference). The same trend was found with PsA (70 years and above [OR, 4.41, 95% CI, 3.07-6.55] compared with those aged 18-29 years).  
• Psoriasis prevalence increased linearly with body mass index (BMI 40 and above [OR, 1.71, 95% CI, 1.54-1.90], with 20-24.9 as the reference). The same trend was found with PsA (BMI 40 and above [OR, 2.09, 95% CI, 1.68-2.59], with 20-24.9 as the reference).  
• Former smokers were at increased risk for disease, compared with people who had never smoked (psoriasis OR, 1.30, 95% CI, 1.22-1.39; PsA OR, 2.15, 95% CI, 1.33-3.78).
• Lower odds were found in uninsured adults (psoriasis OR, 0.43, 95% CI, 0.35-0.52; PsA OR, 0.37, 95% CI, 0.22-0.58) compared with those who were insured, and in those with less than a high school degree (psoriasis OR, 0.72, 95% CI, 0.63-0.82; PsA OR, 0.65, 95% CI, 0.47-0.87) compared with those with a college degree.

“The All of Us research program has demonstrated to be a valuable resource to gain unique dermatologic insights on diverse participant populations,” Ms. Tran said.

“There needs to be improvement in access to quality dermatologic care, as this may help to reduce underdiagnosis of psoriasis and psoriatic arthritis,” she added. Access can be increased  in various ways, including “outreach to underserved communities, equitable distribution of resources, and increased awareness of clinical variations in skin of color.”

Laura Korb Ferris, MD, PhD, professor of dermatology and director of clinical trials for the department of dermatology at University of Pittsburgh Medical Center, said the study is interesting.

A low-level light therapy cap may be a safe, convenient treatment for some patients with central centrifugal cicatricial alopecia, though the treatment effects from a small prospective trial appear to be subtle.

Central centrifugal cicatricial alopecia (CCCA) is a form of scarring hair loss with unknown etiology and no known cure that affects mainly women of African descent.

“The low-level light therapy (LLLT) cap does indeed seem to help with symptoms and mild regrowth in CCCA,” senior study author Amy J. McMichael, MD, told this news organization. “The dual-wavelength cap we used appears to have anti-inflammatory properties, and that makes sense for a primarily inflammatory scarring from of alopecia.

“Quality of life improved with the treatment and there were no reported side effects,” added Dr. McMichael, professor of dermatology at Wake Forest University, Winston-Salem, N.C.

The results of the study were presented in a poster at the annual meeting of the Society for Investigative Dermatology.

The REVIAN RED cap (REVIAN Inc.) used in the study contains 119 light-emitting diodes (LEDs) arrayed on the cap’s interior surface that emit orange (620 nm) and red (660 nm) light.

The hypothesis for how the dual-wavelength lights work is that light is absorbed by the chromophore cytochrome c oxidase in the mitochondrial membrane. This induces the release of nitric oxide and the production of adenosine triphosphate (ATP), which leads to vasodilation, cytokine regulation, and increased transcription and release of growth factors.

LLLT is approved to treat androgenetic alopecia, the authors wrote, but has not been studied as a treatment for CCCA.

To assess the effects of LLLT on CCCA, Dr. McMichael and her colleagues at Wake Forest followed the condition’s progress in five Black women over their 6-month course of treatment. Four participants completed the study.

At baseline, all participants had been on individual stable CCCA treatment regimens for at least 3 months. They continued those treatments along with LLLT therapy throughout the study. The women ranged in age from 38 to 69 years, had had CCCA for an average of 12 years, and their disease severity ranged from stage IIB to IVA.

They were instructed to wear the REVIAN RED cap with the LEDs activated for 10 minutes each day.

At 2, 4, and 6 months, participants self-assessed their symptoms, a clinician evaluated the condition’s severity, and digital photographs were taken.

At 6 months:

• Three patients showed improved Dermatology Life Quality Index (DLQI).
• Three patients showed decreased loss of follicular openings and breakage.
• A dermoscopic image of the scalp of one patient revealed short, regrowing vellus hairs and minimal interfollicular and perifollicular scale.
• No patients reported side effects.

Small study raises big questions

“I hope this study will lead to a larger study that will look at the long-term outcomes of CCCA,” Dr. McMichael said. “This is a nice treatment that does not require application of something to the scalp that may affect hair styling, and it has no systemic side effects.”

Dr. McMichael acknowledges that the small sample size, participants continuing with their individual stable treatments while also undergoing light therapy, and the lack of patients with stage I disease, are weaknesses in the study.

“However, the strength is that none of the patients had side effects or stopped using the treatment due to difficulty with the system,” she added.

Dr. McMichael said she would like to investigate the effects of longer use of the cap and whether the cap can be used to prevent CCCA.

Chesahna Kindred, MD, assistant professor of dermatology at Howard University, Washington, D.C., and founder of Kindred Hair & Skin Center in Columbia, Md., told this news organization that she uses LLLT in her practice.

“I find that LLLT is mildly helpful, or at least does not worsen, androgenetic alopecia,” she said.

“Interestingly, while all four patients had stable disease upon initiating the study, it appears as though two of the four worsened after the use of LLLT, one improved, and one remained relatively stable,” noted Dr. Kindred, who was not involved in the study. “This is important because once there is complete destruction of the follicle, CCCA is difficult to improve.

“Given that there are several options to address inflammation and follicular damage in CCCA, more studies are needed before I would incorporate LLLT into my regular treatment algorithms,” she added.

“Studies like this are important and remind us to not lump all forms of hair loss together,” she said.

A low-level light therapy cap may be a safe, convenient treatment for some patients with central centrifugal cicatricial alopecia, though the treatment effects from a small prospective trial appear to be subtle.

Central centrifugal cicatricial alopecia (CCCA) is a form of scarring hair loss with unknown etiology and no known cure that affects mainly women of African descent.

“The low-level light therapy (LLLT) cap does indeed seem to help with symptoms and mild regrowth in CCCA,” senior study author Amy J. McMichael, MD, told this news organization. “The dual-wavelength cap we used appears to have anti-inflammatory properties, and that makes sense for a primarily inflammatory scarring from of alopecia.

“Quality of life improved with the treatment and there were no reported side effects,” added Dr. McMichael, professor of dermatology at Wake Forest University, Winston-Salem, N.C.

The results of the study were presented in a poster at the annual meeting of the Society for Investigative Dermatology.

The REVIAN RED cap (REVIAN Inc.) used in the study contains 119 light-emitting diodes (LEDs) arrayed on the cap’s interior surface that emit orange (620 nm) and red (660 nm) light.

The hypothesis for how the dual-wavelength lights work is that light is absorbed by the chromophore cytochrome c oxidase in the mitochondrial membrane. This induces the release of nitric oxide and the production of adenosine triphosphate (ATP), which leads to vasodilation, cytokine regulation, and increased transcription and release of growth factors.

LLLT is approved to treat androgenetic alopecia, the authors wrote, but has not been studied as a treatment for CCCA.

To assess the effects of LLLT on CCCA, Dr. McMichael and her colleagues at Wake Forest followed the condition’s progress in five Black women over their 6-month course of treatment. Four participants completed the study.

At baseline, all participants had been on individual stable CCCA treatment regimens for at least 3 months. They continued those treatments along with LLLT therapy throughout the study. The women ranged in age from 38 to 69 years, had had CCCA for an average of 12 years, and their disease severity ranged from stage IIB to IVA.

They were instructed to wear the REVIAN RED cap with the LEDs activated for 10 minutes each day.
