More than 5% of cases of sudden infant death may be linked to maternal obesity, new research showed.

“When a parent has a child that dies of sudden unexplained infant death [SUID], it’s extremely devastating,” said Jan-Marino Ramirez, PhD, the Zain Nadella Endowed Chair in Pediatric Neurosciences at the University of Washington, Seattle, and director of the Center for Integrative Brain Research at Seattle Children’s Hospital. “And the most devastating problem is that there’s no clear answer. Understanding the mechanisms will help parents understand.”

The study was published online in JAMA Pediatrics.

In the United States, approximately 3500 cases of SUID are reported yearly. After educational campaigns in the 1990s demonstrating safe infant sleep positions, rates of these fatalities dropped but have since plateaued.
 

Maternal Obesity During Pregnancy

Rates of maternal obesity are increasing globally, and more than half of women of reproductive age are overweight or obese.

“Maternal obesity before pregnancy affects placental development, gene expression, and has long-term implications,” said Patrick Catalano, MD, a professor in residence at the Departments of Reproductive Endocrinology and Obstetrics and Gynecology at Massachusetts General Hospital and Harvard Medical School in Boston.

Maternal obesity is a well-documented risk factor for adverse outcomes of pregnancy including stillbirth, preterm birth, and admission to the neonatal intensive care unit. Swedish researchers in 2014 reported maternal obesity was linked to an increase in infant mortality that increased with body mass index (BMI), but that study did not look specifically at SUID.

For their new study, Dr. Ramirez and colleagues looked at data from all live births in the United States from 2015 to 2019 recorded by the Centers for Disease Control and Prevention and the National Center for Health Statistics. Of the 18,857,694 live births occurring at 28 weeks of gestation or later, 16,545 infants died of a sudden, unexplained cause.

Rates of SUID in babies born to mothers with obesity increased in a statistically significant, dose-dependent manner relative to normal weight mothers. The unadjusted absolute risks for SUID were 0.74 cases per 1000 births for normal weight mothers, 0.99 cases at BMIs between 30 and 35, 1.17 cases at BMIs between 35 and 40, and 1.47 instances at BMI ≥ 40.

After adjustment for maternal age, race, ethnicity, and level of education, the adjusted odds ratio for a case of SUID was 1.39 among women with the highest levels of obesity (95% CI, 1.31-1.47), according to the researchers.

While the study revealed an association between maternal obesity and SUID, the basis for this connection remains unknown, the investigators noted. One possibility for the link is that obesity increases the risk for obstructive sleep apnea, which can result in intermittent hypoxia. That, in turn, causes oxidative stress, which may possibly have effects on the fetus causing effects that eventually lead to SUID in the infant.

An accompanying editorial by Jacqueline Maya, MD; Marie-France Hivert, MD, MMSc; and Lydia Shook, MD, from the Massachusetts General Hospital and Harvard Medical School, suggested that the SUID is unlikely directly influenced by high maternal BMI but rather by the metabolic concerns related to obesity such as inflammation, insulin resistance, and abnormal lipid metabolism. Epigenetics may also play a role.

“We believe the evidence for this study of an association between prepregnancy obesity and SUID is a call to action for the scientific and medical community to better understand the complex interplay of biological, social, and behavioral factors that may lead to SUID, a devastating complication that no family should experience,” the authors of the editorial wrote.

Dr. Ramirez stressed the importance of not initiating guilt because there are many factors in SUID such as genetics that cannot be controlled.

“We are far from saying a baby died because you were obese; that’s an important message to parents,” he said. What he sees as important, rather, is using this new research to elucidate further mechanisms that may allow for more targeted interventions: “If we discover that it’s due to, for example, sleep apnea, that’s something we can prevent.”

The researchers reported no conflicts of interest.

STOCKHOLM — Current treatments for age-related macular degeneration (AMD) have proved effective and safe. However, these lifelong therapies involve frequent ocular injections. “It can be nerve-wracking for patients about to embark on this journey,” Lisa Olmos de Koo, MD, an ophthalmologist at the University of Washington Eye Institute at Harborview, Seattle, told this news organization.

At the American Society of Retina Specialists (ASRS) 2024 annual meeting, researchers from around the world presented results from clinical studies aiming at reducing the burden of AMD treatment by:

• Identifying patients at a higher risk for degeneration and vision loss who will be more likely to respond to treatment
• Developing gene therapies that promise to drastically reduce or eliminate the need for injections
• Testing novel drugs with mechanisms of action that use different pathways than currently available medications, offering patients more options and longer-lasting treatments

“It’s exciting to see the broad range of novel approaches in AMD treatments,” Dimitra Skondra, MD, PhD, a retina specialist at the University of Chicago, told this news organization.
 

Whom to Treat

Anti–vascular endothelial growth factor (anti-VEGF) therapies shook the AMD treatment scene when they were introduced in the early 2000s. “It was incredible,” Dr. Olmos de Koo said. Patients with wet AMD could finally see their vision improve with each injection. “It was a great motivator to begin therapy.”

However, patients with the advanced form of dry AMD involving geographic atrophy (GA) have had less luck. Pegcetacoplan and avacincaptad pegol, the only US Food and Drug Administration (FDA)–approved treatments for GA, slow the progression of the disease but do not restore vision. In fact, vision continues to decline. “Patients want to understand if their condition is worsening and whether treatment is necessary,” Dr. Olmos de Koo said.

Researchers are developing tools to help clinicians identify lesions that are more likely to grow and reach the fovea, causing vision loss.

For example, Cleveland Clinic’s Katherine Talcott, MD, presented an analysis of the GATHER1 and GATHER2 clinical trials that showed that spectral domain optical coherence tomography can be used to examine the integrity of the ellipsoid zone for predicting GA growth and treatment response. The retina’s ellipsoid zone contains densely packed mitochondria within the inner segments of the photoreceptor cells and plays a critical role in visual function.

Dr. Talcott and her team found that more severe baseline damage of the ellipsoid zone was associated with a faster growth rate of GA.

Another analysis of the same trials, presented by Dilraj Grewal, MD, associate professor of ophthalmology, vitreoretinal surgery, and uveitis at Duke Eye Center, Durham, North Carolina, showed that intravitreal administration of avacincaptad pegol efficiently reduced GA growth whether the treated eye developed macular neovascularization or not. Avacincaptad pegol is a complement factor inhibitor that aims to reduce complement-mediated inflammation and tissue damage in the retina.

Dr. Olmos de Koo explained that clinical trials have shown that more patients develop neovascularization when treated for dry GA than they would if left untreated. This has raised the question among clinicians whether the increased risk is a valid reason to avoid treatment. “This useful analysis tells us that there is still a rationale to continue treating GA, even while you’re concurrently treating the wet component with anti-VEGF therapies,” she said.

Another biomarker of GA growth is the position of the lesion at baseline. Daniel Muth, MD, an ophthalmology consultant at the Karolinska Institutet in Stockholm, Sweden, reported the results from a long-term, retrospective analysis of fundus autofluorescence in patients with GA. His semiautomated artificial intelligence–based analysis showed that patients affected bilaterally, but whose fovea was not yet affected, exhibited a faster GA growth rate than fovea-involving patients, with an approximate 15% risk for fovea involvement.

“Those patients whose atrophy has not yet affected the very center are the most likely to benefit from preventive therapy,” Dr. Olmos de Koo said. “Left untreated, a large proportion of them will develop atrophy that does affect their central vision — that’s their reading or facial recognition ability.”

“Potential predictors of rapid growth rates guide us clinically and allow patients to make more informed decisions about whether to pursue treatments that require frequent interventions,” Dr. Olmos de Koo said.

Forecasting the side to which the cost-benefit balance of treatment will tip for each patient is a complex decision-making process, she explained. “A patient is not a statistic, but these predictive studies are one important piece of the pie.”
 

The Promise of Gene Therapy

The one-and-done promise of gene therapy could rattle the field once again. Trials presented at the ASRS24 showed a drastic reduction (from 85% to 95%) in the number of anti-VEGF and complement treatments needed following gene therapy injection, improving patient vision while relieving them from the stress of monthly injections.

But researchers are still debating the optimal corticosteroid regimen that is required for reducing the inflammatory response associated with the administration of gene therapies, especially those that use viral vectors. The main controversy is whether systemic immunosuppression is necessary or if local therapies, such as topical and intravitreal administration, can suffice.

Results presented at the meeting suggest that local therapies alone can be effective, potentially reducing the need for systemic immunosuppression.

The LUNA trial evaluated the efficacy and tolerability of ixoberogene soroparvovec, a therapy that delivers an anti-VEGF gene into the eye. Investigators included various prophylactic regimens, including local corticosteroids with and without oral prednisone. They found that local corticosteroid therapy alone effectively reduced inflammation.

Biopharma company 4DMT conducted the PRISM study, which examined a dual transgene therapy for neovascular AMD. Patients in this trial received a 20-week topical steroid taper. Only one patient (of 39) required a 6-week extension of steroid therapy. No patients experienced clinically significant intraocular inflammation, indicating that local corticosteroid therapy was effective in managing immune responses.

Currently, gene therapy clinical trials are designed for patients who have failed standard therapy or require frequent injections. “Once we figure out possible long-term side effects and how to deal with inflammation, [gene therapy] could reach many more patients,” Dr. Olmos de Koo said.
 

New Approaches Enter Pipeline

While gene therapy brings excitement to the field, it might not be for everyone, experts agreed at the ASRS24. New agents are being evaluated to offer a broader range of treatment options with longer-lasting efficacy. Results from early-phase trials presented at the meeting show favorable safety and efficacy signals.

“Finally, after a long time, we have a lot of exciting drugs for geographic atrophy in the pipeline that seem to be safe, with many studies also showing a functional outcome in addition to anatomical outcome,” Dr. Skondra told this news organization.

Current FDA-approved treatments for GA focus on inhibiting the humoral arm of the immune system through C3 and C5 inhibitors. However, a new approach targets both the humoral and cellular arms of the immune response by inhibiting macrophages that release pro-inflammatory cytokines. The goal is to convert these macrophages to a “resolution state,” potentially reducing the release of inflammatory cytokines and offering a more comprehensive treatment for wet and dry AMD, said Rishi Singh, MD, a retina surgeon at the Cole Eye Institute, Cleveland Clinic.

AVD-104, a sialic acid–coated nanoparticle developed by Aviceda Therapeutics, is a promising candidate in this approach. This 100-nm-in-diameter particle, which is only as heavy as 20 hydrogen atoms, is designed for better tissue penetration and has a pharmacokinetic profile lasting 3-4 months after a single intravitreal dose.

AVD-104 aims to repolarize macrophages into a resolution phenotype and decreases complement factor overamplification through direct binding to complement factor H, which downregulates C3 production in immune cells. This dual-action approach could offer a more effective and long-lasting treatment option.

Dr. Singh, who presented the phase 2/3 SIGLEC clinical trial assessing AVD-104, said a single dose resulted in significantly slower rates of disease progression as early as 1 month post-treatment and a notable decrease in junctional zone hyper-autofluorescence.

In addition, about 40% of patients gained vision, which was unexpected but a pleasant surprise, Dr. Singh said. “This is a small study. I don’t want anyone to walk away with the conclusion that we’ve figured out how to improve visual acuity in GA. But it’s promising.”

Other researchers are tackling GA by focusing on therapies that aim to intervene before the complement system is activated.

ONL1204 is a novel agent designed to inhibit the activation of the tumor necrosis factor FAS receptor, which is activated and upregulated in a disease state and is implicated in multiple cell death and inflammatory pathways.

Multiple preclinical models of AMD have shown that ONL1204 preserves retinal cells and inhibits inflammation by inhibiting the FAS receptor. Phase 1 trial results presented at the meeting showed that ONL1204 was safe and showed strong efficacy signals as early as 6 months after treatment initiation.

“We need to be cautiously optimistic,” Dr. Skondra said. “Larger studies will tell us if these signals are real. But it’s a very exciting time. I’m happy to see different mechanisms of action besides the complement because we can attack the disease from multiple fronts.”

Dr. Grewal declared interests with Eyepoint, Iveric Bio, Regeneron, Alumis, Apellis, DORC, and Genentech. Dr. Muth declared interests with Bayer, Canon, and Roche. Dr. Olmos de Koo declared interests with Alcon and Pixium Vision. Dr. Singh declared interests with Gyroscope, 4DMT, Aviceda, Eyepoint, Alcon, Bausch and Lomb, Novartis, and Regeneron. Dr. Skondra declared interests with Biogen, Iveric Bio, Allergan, and Trinity Health Science. Dr. Talcott declared interests with Bausch and Lomb, Eyepoint, Regeneron, REGENXBIO, Zeiss, Apellis, Genentech, Alimera, Outlook, and Iveric Bio.

Dr. Olmos de Koo explained that clinical trials have shown that more patients develop neovascularization when treated for dry GA than they would if left untreated. This has raised the question among clinicians whether the increased risk is a valid reason to avoid treatment. “This useful analysis tells us that there is still a rationale to continue treating GA, even while you’re concurrently treating the wet component with anti-VEGF therapies,” she said.

Another biomarker of GA growth is the position of the lesion at baseline. Daniel Muth, MD, an ophthalmology consultant at the Karolinska Institutet in Stockholm, Sweden, reported the results from a long-term, retrospective analysis of fundus autofluorescence in patients with GA. His semiautomated artificial intelligence–based analysis showed that patients affected bilaterally, but whose fovea was not yet affected, exhibited a faster GA growth rate than fovea-involving patients, with an approximate 15% risk for fovea involvement.

“Those patients whose atrophy has not yet affected the very center are the most likely to benefit from preventive therapy,” Dr. Olmos de Koo said. “Left untreated, a large proportion of them will develop atrophy that does affect their central vision — that’s their reading or facial recognition ability.”

“Potential predictors of rapid growth rates guide us clinically and allow patients to make more informed decisions about whether to pursue treatments that require frequent interventions,” Dr. Olmos de Koo said.

Forecasting the side to which the cost-benefit balance of treatment will tip for each patient is a complex decision-making process, she explained. “A patient is not a statistic, but these predictive studies are one important piece of the pie.”
 

The Promise of Gene Therapy

The one-and-done promise of gene therapy could rattle the field once again. Trials presented at the ASRS24 showed a drastic reduction (from 85% to 95%) in the number of anti-VEGF and complement treatments needed following gene therapy injection, improving patient vision while relieving them from the stress of monthly injections.

But researchers are still debating the optimal corticosteroid regimen that is required for reducing the inflammatory response associated with the administration of gene therapies, especially those that use viral vectors. The main controversy is whether systemic immunosuppression is necessary or if local therapies, such as topical and intravitreal administration, can suffice.

Results presented at the meeting suggest that local therapies alone can be effective, potentially reducing the need for systemic immunosuppression.

The LUNA trial evaluated the efficacy and tolerability of ixoberogene soroparvovec, a therapy that delivers an anti-VEGF gene into the eye. Investigators included various prophylactic regimens, including local corticosteroids with and without oral prednisone. They found that local corticosteroid therapy alone effectively reduced inflammation.

Biopharma company 4DMT conducted the PRISM study, which examined a dual transgene therapy for neovascular AMD. Patients in this trial received a 20-week topical steroid taper. Only one patient (of 39) required a 6-week extension of steroid therapy. No patients experienced clinically significant intraocular inflammation, indicating that local corticosteroid therapy was effective in managing immune responses.

Currently, gene therapy clinical trials are designed for patients who have failed standard therapy or require frequent injections. “Once we figure out possible long-term side effects and how to deal with inflammation, [gene therapy] could reach many more patients,” Dr. Olmos de Koo said.
 

New Approaches Enter Pipeline

While gene therapy brings excitement to the field, it might not be for everyone, experts agreed at the ASRS24. New agents are being evaluated to offer a broader range of treatment options with longer-lasting efficacy. Results from early-phase trials presented at the meeting show favorable safety and efficacy signals.

“Finally, after a long time, we have a lot of exciting drugs for geographic atrophy in the pipeline that seem to be safe, with many studies also showing a functional outcome in addition to anatomical outcome,” Dr. Skondra told this news organization.

Current FDA-approved treatments for GA focus on inhibiting the humoral arm of the immune system through C3 and C5 inhibitors. However, a new approach targets both the humoral and cellular arms of the immune response by inhibiting macrophages that release pro-inflammatory cytokines. The goal is to convert these macrophages to a “resolution state,” potentially reducing the release of inflammatory cytokines and offering a more comprehensive treatment for wet and dry AMD, said Rishi Singh, MD, a retina surgeon at the Cole Eye Institute, Cleveland Clinic.

AVD-104, a sialic acid–coated nanoparticle developed by Aviceda Therapeutics, is a promising candidate in this approach. This 100-nm-in-diameter particle, which is only as heavy as 20 hydrogen atoms, is designed for better tissue penetration and has a pharmacokinetic profile lasting 3-4 months after a single intravitreal dose.

AVD-104 aims to repolarize macrophages into a resolution phenotype and decreases complement factor overamplification through direct binding to complement factor H, which downregulates C3 production in immune cells. This dual-action approach could offer a more effective and long-lasting treatment option.

Dr. Singh, who presented the phase 2/3 SIGLEC clinical trial assessing AVD-104, said a single dose resulted in significantly slower rates of disease progression as early as 1 month post-treatment and a notable decrease in junctional zone hyper-autofluorescence.

In addition, about 40% of patients gained vision, which was unexpected but a pleasant surprise, Dr. Singh said. “This is a small study. I don’t want anyone to walk away with the conclusion that we’ve figured out how to improve visual acuity in GA. But it’s promising.”

Other researchers are tackling GA by focusing on therapies that aim to intervene before the complement system is activated.

ONL1204 is a novel agent designed to inhibit the activation of the tumor necrosis factor FAS receptor, which is activated and upregulated in a disease state and is implicated in multiple cell death and inflammatory pathways.

Multiple preclinical models of AMD have shown that ONL1204 preserves retinal cells and inhibits inflammation by inhibiting the FAS receptor. Phase 1 trial results presented at the meeting showed that ONL1204 was safe and showed strong efficacy signals as early as 6 months after treatment initiation.

“We need to be cautiously optimistic,” Dr. Skondra said. “Larger studies will tell us if these signals are real. But it’s a very exciting time. I’m happy to see different mechanisms of action besides the complement because we can attack the disease from multiple fronts.”

An ancient virus that infected our ancestors tens of millions of years ago may be helping to fuel cancer today, according to a fascinating new study in Science Advances. Targeting these viral remnants still lingering in our DNA could lead to more effective cancer treatment with fewer side effects, the researchers said.

The study “gives a better understanding of how gene regulation can be impacted by these ancient retroviral sequences,” said Dixie Mager, PhD, scientist emeritus at the Terry Fox Laboratory at the British Columbia Cancer Research Institute, Vancouver, British Columbia, Canada. (Mager was not involved in the study.)

Long thought to be “junk” DNA with no biologic function, “endogenous retroviruses,” which have mutated over time and lost their ability to create the virus, are now known to regulate genes — allowing some genes to turn on and off. Research in recent years suggests they may play a role in diseases like cancer.

But scientists weren’t exactly sure what that role was, said senior study author Edward Chuong, PhD, a genome biologist at the University of Colorado Boulder.

Most studies have looked at whether endogenous retroviruses code for proteins that influence cancer. But these ancient viral strands usually don’t code for proteins at all.

Dr. Chuong took a different approach. Inspired by scientists who’ve studied how viral remnants regulate positive processes (immunity, brain development, or placenta development), he and his team explored whether some might regulate genes that, once activated, help cancer thrive.

Borrowing from epigenomic analysis data (data on molecules that alter gene expression) for 21 cancers mapped by the Cancer Genome Atlas, the researchers identified 19 virus-derived DNA sequences that bind to regulatory proteins more in cancer cells than in healthy cells. All of these could potentially act as gene regulators that promote cancer.

The researchers homed in on one sequence, called LTR10, because it showed especially high activity in several cancers, including lung and colorectal cancer. This DNA segment comes from a virus that entered our ancestors’ genome 30 million years ago, and it’s activated in a third of colorectal cancers.

Using the gene editing technology clustered regularly interspaced short palindromic repeats (CRISPR), Dr. Chuong’s team silenced LTR10 in colorectal cancer cells, altering the gene sequence so it couldn’t bind to regulatory proteins. Doing so dampened the activity of nearby cancer-promoting genes.

“They still behaved like cancer cells,” Dr. Chuong said. But “it made the cancer cells more susceptible to radiation. That would imply that the presence of that viral ‘switch’ actually helped those cancer cells survive radiation therapy.”

Previously, two studies had found that viral regulators play a role in promoting two types of cancer: Leukemia and prostate cancer. The new study shows these two cases weren’t flukes. All 21 cancers they looked at had at least one of those 19 viral elements, presumably working as cancer enhancers.

The study also identified what activates LTR10 to make it promote cancer. The culprit is a regulator protein called mitogen-activated protein (MAP) kinase, which is overactivated in about 40% of all human cancers.

Some cancer drugs — MAP kinase inhibitors — already target MAP kinase, and they’re often the first ones prescribed when a patient is diagnosed with cancer, Dr. Chuong said. As with many cancer treatments, doctors don’t know why they work, just that they do.

“By understanding the mechanisms in the cell, we might be able to make them work better or further optimize their treatment,” he said.

“MAP kinase inhibitors are really like a sledgehammer to the cell,” Dr. Chuong said — meaning they affect many cellular processes, not just those related to cancer.

“If we’re able to say that these viral switches are what’s important, then that could potentially help us develop a more targeted therapy that uses something like CRISPR to silence these viral elements,” he said. Or it could help providers choose a MAP kinase inhibitor from among the dozens available best suited to treat an individual patient and avoid side effects.  

Still, whether the findings translate to real cancer patients remains to be seen. “It’s very, very hard to go the final step of showing in a patient that these actually make a difference in the cancer,” Dr. Mager said.

More lab research, human trials, and at least a few years will be needed before this discovery could help treat cancer. “Directly targeting these elements as a therapy would be at least 5 years out,” Dr. Chuong said, “partly because that application would rely on CRISPR epigenome editing technology that is still being developed for clinical use.”

To the Editor:

Henoch-Schönlein purpura (HSP)(also known as IgA vasculitis) is a small vessel vasculitis characterized by deposition of IgA in small vessels, resulting in the development of purpura on the legs. Based on the European Alliance of Associations for Rheumatology criteria,¹ the patient also must have at least 1 of the following: arthritis, arthralgia, abdominal pain, leukocytoclastic vasculitis with IgA deposition, or kidney involvement. The disease can be triggered by infection—with more than 75% of patients reporting an antecedent upper respiratory tract infection²—as well as medications, circulating immune complexes, certain foods, vaccines, and rarely cancer.^3,4 The disease more commonly occurs in children but also can affect adults.

Several cases of HSP have been reported following COVID-19 vaccination.⁵ We report a case of HSP developing days after the messenger RNA Pfizer-BioNTech COVID-19 vaccine booster that was associated with anti-Smith and anti–double-stranded DNA (dsDNA) antibodies as well as antineutrophil cytoplasmic antibodies (ANCAs).

A 24-year-old man presented to dermatology with a rash of 3 weeks’ duration that first appeared 1 week after receiving his second booster of the messenger RNA Pfizer-BioNTech COVID-19 vaccine. Physical examination revealed petechiae with nonblanching erythematous macules and papules covering the legs below the knees (Figure 1) as well as the back of the right arm. A few days later, he developed arthralgia in the knees, hands, and feet. The patient denied any recent infections as well as respiratory and urinary tract symptoms. Approximately 10 days after the rash appeared, he developed epigastric abdominal pain that gradually worsened and sought care from his primary care physician, who ordered computed tomography and referred him for endoscopy. Computed tomography with and without contrast was suspicious for colitis. Colonoscopy and endoscopy were unremarkable. Laboratory tests were notable for elevated white blood cell count (17.08×10³/µL [reference range, 3.66–10.60×10³/µL]), serum IgA (437 mg/dL [reference range, 70–400 mg/dL]), C-reactive protein (1.5 mg/dL [reference range, <0.5 mg/dL]), anti-Smith antibody (28.1 CU [reference range, <20 CU), positive antinuclear antibody with titer (1:160 [reference range, <1:80]), anti-dsDNA (40.4 IU/mL [reference range, <27 IU/mL]), and cytoplasmic ANCA (c-ANCA) titer (1:320 [reference range, <1:20]). Blood urea nitrogen, creatinine, and estimated glomerular filtration rate were all within reference range. Urinalysis with microscopic examination was notable for 2 to 5 red blood cells per high-power field (reference range, 0) and proteinuria of 1+ (reference range, negative for protein).

The patient’s rash progressively worsened over the next few weeks, spreading proximally on the legs to the buttocks and the back of both elbows. A repeat complete blood cell count showed resolution of the leukocytosis. Two biopsies were taken from a lesion on the left proximal thigh: 1 for hematoxylin and eosin stain for histopathologic examination and 1 for direct immunofluorescence examination.

The patient was preliminarily diagnosed with HSP, and dermatology prescribed oral tofacitinib 5 mg twice daily for 5 days, which was supposed to be increased to 10 mg twice daily on the sixth day of treatment; however, the patient discontinued the medication after 4 days based on his primary care physician’s recommendation due to clotting concerns. The rash and arthralgia temporarily improved for 1 week, then relapsed.

Histopathology revealed neutrophils surrounding and infiltrating small dermal blood vessel walls as well as associated neutrophilic debris and erythrocytes, consistent with leukocytoclastic vasculitis (Figure 2). Direct immunofluorescence was negative for IgA antibodies. His primary care physician, in consultation with his dermatologist, then started the patient on oral prednisone 70 mg once daily for 7 days with a plan to taper. Three days after prednisone was started, the arthralgia and abdominal pain resolved, and the rash became lighter in color. After 1 week, the rash resolved completely.

Due to the unusual antibodies, the patient was referred to a rheumatologist, who repeated the blood tests approximately 1 week after the patient started prednisone. The tests were negative for anti-Smith, anti-dsDNA, and c-ANCA but showed an elevated atypical perinuclear ANCA (p-ANCA) titer of 1:80 (reference range [negative], <1:20). A repeat urinalysis was unremarkable. The patient slowly tapered the prednisone over the course of 3 months and was subsequently lost to follow-up. The rash and other symptoms had not recurred as of the patient’s last physician contact. The most recent laboratory results showed a white blood cell count of 14.0×10³/µL (reference range, 3.4–10.8×10³/µL), likely due to the prednisone; blood urea nitrogen, creatinine, and estimated glomerular filtration rate were within reference range. The urinalysis was notable for occult blood and was negative for protein. C-reactive protein was 1 mg/dL (reference range, 0–10 mg/dL); p-ANCA, c-ANCA, and atypical p-ANCA, as well as antinuclear antibody, were negative. As of his last follow-up, the patient felt well.

The major differential diagnoses for our patient included HSP, ANCA vasculitis, and systemic lupus erythematosus. Although ANCA vasculitis has been reported after SARS-CoV-2 infection,⁶ the lack of pulmonary symptoms made this diagnosis unlikely.⁷ Although our patient initially had elevated anti-Smith and anti-dsDNA antibodies as well as mild renal involvement, he fulfilled at most only 2 of the 11 criteria necessary for diagnosing lupus: malar rash, discoid rash (includes alopecia), photosensitivity, ocular ulcers, nonerosive arthritis, serositis, renal disorder (protein >500 mg/24 h, red blood cells, casts), neurologic disorder (seizures, psychosis), hematologic disorders (hemolytic anemia, leukopenia), ANA, and immunologic disorder (anti-Smith). Four of the 11 criteria are necessary for the diagnosis of lupus.⁸

Torraca et al⁷ reported a case of HSP with positive c-ANCA (1:640) in a patient lacking pulmonary symptoms who was diagnosed with HSP. Cytoplasmic ANCA is not a typical finding in HSP. However, the additional findings of anti-Smith, anti-dsDNA, and mildly elevated atypical p-ANCA antibodies in our patient were unexpected and could be explained by the proposed pathogenesis of HSP—an overzealous immune response resulting in aberrant antibody complex deposition with ensuing complement activation.^5,9 Production of these additional antibodies could be part of the overzealous response to COVID-19 vaccination.

The disease can be triggered by infection—with more than 75% of patients reporting an antecedent upper respiratory tract infection²—as well as medications, circulating immune complexes, certain foods, vaccines, and rarely cancer.^3,4 The disease more commonly occurs in children but also can affect adults.

Several cases of HSP have been reported following COVID-19 vaccination.⁵ We report a case of HSP developing days after the messenger RNA Pfizer-BioNTech COVID-19 vaccine booster that was associated with anti-Smith and anti–double-stranded DNA (dsDNA) antibodies as well as antineutrophil cytoplasmic antibodies (ANCAs).

A 24-year-old man presented to dermatology with a rash of 3 weeks’ duration that first appeared 1 week after receiving his second booster of the messenger RNA Pfizer-BioNTech COVID-19 vaccine. Physical examination revealed petechiae with nonblanching erythematous macules and papules covering the legs below the knees (Figure 1) as well as the back of the right arm. A few days later, he developed arthralgia in the knees, hands, and feet. The patient denied any recent infections as well as respiratory and urinary tract symptoms. Approximately 10 days after the rash appeared, he developed epigastric abdominal pain that gradually worsened and sought care from his primary care physician, who ordered computed tomography and referred him for endoscopy. Computed tomography with and without contrast was suspicious for colitis. Colonoscopy and endoscopy were unremarkable. Laboratory tests were notable for elevated white blood cell count (17.08×10³/µL [reference range, 3.66–10.60×10³/µL]), serum IgA (437 mg/dL [reference range, 70–400 mg/dL]), C-reactive protein (1.5 mg/dL [reference range, <0.5 mg/dL]), anti-Smith antibody (28.1 CU [reference range, <20 CU), positive antinuclear antibody with titer (1:160 [reference range, <1:80]), anti-dsDNA (40.4 IU/mL [reference range, <27 IU/mL]), and cytoplasmic ANCA (c-ANCA) titer (1:320 [reference range, <1:20]). Blood urea nitrogen, creatinine, and estimated glomerular filtration rate were all within reference range. Urinalysis with microscopic examination was notable for 2 to 5 red blood cells per high-power field (reference range, 0) and proteinuria of 1+ (reference range, negative for protein).

The patient’s rash progressively worsened over the next few weeks, spreading proximally on the legs to the buttocks and the back of both elbows. A repeat complete blood cell count showed resolution of the leukocytosis. Two biopsies were taken from a lesion on the left proximal thigh: 1 for hematoxylin and eosin stain for histopathologic examination and 1 for direct immunofluorescence examination.

The patient was preliminarily diagnosed with HSP, and dermatology prescribed oral tofacitinib 5 mg twice daily for 5 days, which was supposed to be increased to 10 mg twice daily on the sixth day of treatment; however, the patient discontinued the medication after 4 days based on his primary care physician’s recommendation due to clotting concerns. The rash and arthralgia temporarily improved for 1 week, then relapsed.

Histopathology revealed neutrophils surrounding and infiltrating small dermal blood vessel walls as well as associated neutrophilic debris and erythrocytes, consistent with leukocytoclastic vasculitis (Figure 2). Direct immunofluorescence was negative for IgA antibodies. His primary care physician, in consultation with his dermatologist, then started the patient on oral prednisone 70 mg once daily for 7 days with a plan to taper. Three days after prednisone was started, the arthralgia and abdominal pain resolved, and the rash became lighter in color. After 1 week, the rash resolved completely.

Due to the unusual antibodies, the patient was referred to a rheumatologist, who repeated the blood tests approximately 1 week after the patient started prednisone. The tests were negative for anti-Smith, anti-dsDNA, and c-ANCA but showed an elevated atypical perinuclear ANCA (p-ANCA) titer of 1:80 (reference range [negative], <1:20). A repeat urinalysis was unremarkable. The patient slowly tapered the prednisone over the course of 3 months and was subsequently lost to follow-up. The rash and other symptoms had not recurred as of the patient’s last physician contact. The most recent laboratory results showed a white blood cell count of 14.0×10³/µL (reference range, 3.4–10.8×10³/µL), likely due to the prednisone; blood urea nitrogen, creatinine, and estimated glomerular filtration rate were within reference range. The urinalysis was notable for occult blood and was negative for protein. C-reactive protein was 1 mg/dL (reference range, 0–10 mg/dL); p-ANCA, c-ANCA, and atypical p-ANCA, as well as antinuclear antibody, were negative. As of his last follow-up, the patient felt well.

The major differential diagnoses for our patient included HSP, ANCA vasculitis, and systemic lupus erythematosus. Although ANCA vasculitis has been reported after SARS-CoV-2 infection,⁶ the lack of pulmonary symptoms made this diagnosis unlikely.⁷ Although our patient initially had elevated anti-Smith and anti-dsDNA antibodies as well as mild renal involvement, he fulfilled at most only 2 of the 11 criteria necessary for diagnosing lupus: malar rash, discoid rash (includes alopecia), photosensitivity, ocular ulcers, nonerosive arthritis, serositis, renal disorder (protein >500 mg/24 h, red blood cells, casts), neurologic disorder (seizures, psychosis), hematologic disorders (hemolytic anemia, leukopenia), ANA, and immunologic disorder (anti-Smith). Four of the 11 criteria are necessary for the diagnosis of lupus.⁸

Torraca et al⁷ reported a case of HSP with positive c-ANCA (1:640) in a patient lacking pulmonary symptoms who was diagnosed with HSP. Cytoplasmic ANCA is not a typical finding in HSP. However, the additional findings of anti-Smith, anti-dsDNA, and mildly elevated atypical p-ANCA antibodies in our patient were unexpected and could be explained by the proposed pathogenesis of HSP—an overzealous immune response resulting in aberrant antibody complex deposition with ensuing complement activation.^5,9 Production of these additional antibodies could be part of the overzealous response to COVID-19 vaccination.

Dear Friends,

This issue of The New Gastroenterologist marks my first year completed as faculty. It has been both the best year and the HARDEST year. I celebrated many successes, felt intellectually and emotionally drained by difficult and complicated cases, and learned that there is so much more I still do not know. But that’s the beauty of our field — we are constantly learning to be better physicians for our patients. To trainees and my fellow gastroenterologists in practice, never stop asking questions!

In this issue’s “In Focus,” Dr. Rajan Singh and Dr. Baharak Moshiree describe a practical approach to patients with bloating by evaluating and investigating the pathophysiology and etiology of bloating, such as food intolerances, visceral hypersensitivity, pelvic floor dysfunction, abdominophrenic dyssynergia, gut dysmotility, and small intestinal bacterial overgrowth, as well as treatment management. In the “Short Clinical Review” section, Dr. Ahmad Bazarbashi and his colleagues review when to refer complex polyps to an advanced endoscopist and the different techniques of advanced tissue resection, including endoscopic mucosal resection, endoscopic submucosal dissection, submucosal tunneling endoscopic resection, and full thickness resection.

Locum practices have become more popular among gastroenterologists. Dr. Catherine Bartholomew is a retired professor of medicine who was chief of gastroenterology at an academic institution, and is now working as a GI locum after retirement. She details what a locum tenens is, the role of the company, being an independent contractor, and the benefits.

Navigating and negotiating maternity and paternity leave may be challenging in private practice. Dr. Marybeth Spanarkel gives her opinion on the nuances of maternity/paternity leave in private practices, what it may mean financially, and things to inquire of the practice if planning to have children.

As we move from joining non-traditional practices and navigating family planning with private practices, Dr. Vasu Appalaneni shares her experiences with financial planning for retirement. She describes ways to financially plan a retirement, but also to consider aspects that affect financial well-being during retirement, including healthcare coverage, lifestyle and traveling, legal and estate, professional development, and emotional and social support.

If you are interested in contributing or have ideas for future TNG topics, please contact me ([email protected]) or Danielle Kiefer ([email protected]), communications/managing editor of TNG.

Until next time, I leave you with a historical fun fact because we would not be where we are not without appreciating where we were: The first colonic polypectomy using an electrosurgical snare was performed by Dr. Hiromi Shinya at Beth Israel Medical Center in New York City, in 1969.

TORONTO — Lawrence A. Schachner, MD, would like pediatric dermatologists to adopt a “toxic agent of the year” to raise awareness about the potential harm related to certain topical treatments in babies and young children.

Dr. Schachner, director of the Division of Pediatric Dermatology in the Department of Dermatology & Cutaneous Surgery at the University of Miami, Coral Gables, Florida, said he got the idea from the American Contact Dermatitis Society, which annually names the “Allergen of the Year.”

In pediatric dermatology, the list of potentially toxic products includes topical analgesics such as Castellani paint used for skin infections, alcohols used for umbilical care in newborns, and henna dye used in cosmetics, said Dr. Schachner, professor of pediatrics and dermatology at the University of Miami.

“Any one of those would be excellent toxic substances of the year” that could be the focus of an educational campaign, he told this news organization following his presentation on “Toxicology of Topical Ingredients in Pediatric Dermatology” at the annual meeting of the Society for Pediatric Dermatology on July 14.

Benzene might also be a good candidate for the list, although the jury seems to be still out on its toxicity, said Dr. Schachner.

He talked about the “four Ps” of poisoning — the physician, pharmacy, parents, and pharmaceutical manufacturing — which all have some responsibility for errors that lead to adverse outcomes but can also take steps to prevent them.

During his presentation, Dr. Schachner discussed how babies are especially sensitive to topical therapies, noting that a baby’s skin is thinner and more permeable than that of an adult. And children have a greater body surface-to-weight ratio, so they absorb more substances through their skin.

He also noted that babies lack natural moisturizing factors, and their skin barrier isn’t mature until about age 3-5 years, stressing the need for extreme care when applying a topical agent to a baby’s skin.

Tragic Stories

Dr. Schachner pointed to some instances of mishaps related to toxic topical substances in children. There was the outbreak in the early 1980s of accidental hexachlorophene poisoning among children in France exposed to talc “baby powder.” Of the 204 affected children, 36 died.

The cause was a manufacturing error; the product contained 6.3% hexachlorophene, as opposed to the 0.1% limit recommended by the US Food and Drug Administration (FDA).

Local anesthetics, including lidocaine, dibucaine, and prilocaine, can cause local anesthetic systemic toxicity, a syndrome with symptoms that include central nervous system depression, seizures, and cardiotoxicity. Dr. Schachner described the case of a 3-year-old who developed methemoglobinemia, with seizures, after treatment with an excessive amount of eutectic mixture of local anesthetics (EMLA) cream, which contains both lidocaine and prilocaine.

EMLA shouldn’t be used with methemoglobinemia-inducing agents, such as some antimalarials, analgesics, anesthetics, and antineoplastic agents. It’s not recommended in neonates or for those under 12 months if receiving methemoglobinemia-inducing agents, “and I would keep an eye on it after 12 months of age,” said Dr. Schachner.

He cited a retrospective review of topical lidocaine toxicity in pediatric patients reported to the National Poison Data System from 2000 to 2020. It found 37 cases of toxicity, the most common from application prior to dermatologic procedures (37.5%), which led to two deaths.
 

Not Benign Agents

“These are not benign agents; we have to use them correctly,” Dr. Schachner stressed. When discussing alcohols and antiseptics, he noted that phenol is found in a variety of household disinfectants, gargling products, ointments, and lip balms. Phenol can be used as a chemical peel and is the antiseptic component of Castellani paint. He also referred to cases of alcohol intoxication linked to umbilical care in newborns.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure. Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

Dr. Schachner is chair of Stiefel Laboratories and is an investigator with: Astellas, Berg Pharma, Celgene, Ferndale Labs, Lilly, Medimetriks Pharmaceuticals, Novartis, Organogenesis, Pfizer, Sciton; is a consultant for: Alphyn, Amryt Pharma, Beiersdorf, Brickell, Cutanea, Hoth, Lexington, Mustela, TopMD, Noble Pharma; a speaker for: Novartis, Sanofi-Regeneron, CeraVe; is on the advisory boards of: Almirall, Alphyn, Apogee, Aslan, Biofrontera, CeraVe, Krystal Biotech, Mustela, Noble Pharma, Pfizer, Pierre Fabre, Sanofi-Regeneron; and owns stocks in: TopMD and Alphyn. Dr. Maguiness had no relevant conflicts of interest.

Benzene at elevated levels has been found in some topical benzoyl peroxide acne products and in some sunscreens. There have been suggestions, not strongly substantiated, that benzene may increase the risk for cancer, especially leukemias.

But there is sparse data on the absorption and toxicity of benzene exposure with sunscreen use. The data, he said, include an analysis of National Health and Nutrition Examination Survey data, which found that people who regularly used sunscreens were less likely to have elevated benzene levels compared with those who didn’t use sunscreens.

Turning to insecticides, Dr. Schachner discussed N,N-diethyl-m-toluamide (DEET), the active ingredient in many insect repellents. It helps avoid “some terrible diseases,” including mosquito-borne illnesses such as malaria and tick-borne conditions such as Lyme disease, and is available in several convenient formulations, he said.

When used on children, the American Academy of Pediatrics (AAP) recommends products with no more than 30% DEET. And insect repellents are not recommended for children younger than 2 months, or under clothing or damaged skin, he said.

Dr. Schachner referred to a case series of 18 children who developed DEET-induced encephalopathy; 13 (72%) involved dermal exposure. Three of those with cutaneous exposure died, mostly from neurologic, respiratory, and cardiac issues. “What’s very striking is that 55% of the kids were exposed to DEET of 20% or less, even though the AAP approves DEET at 30%, so maybe that’s something we have to look at,” he said.
 

Medication Patches

With medication patches, especially fentanyl transdermal patches, much can go wrong when it comes to children. This was highlighted by the cases Schachner cited, including an infant who developed acute cytotoxic cerebellar edema from fentanyl patch intoxication.

In another case, emergency room staff found a fentanyl patch stuck to the back of a 3-year-old girl. A CT scan showed global cerebral edema, and the patient progressed to brain death. “This is not a unique case; there have been over 10 such cases in the United States,” said Dr. Schachner. “We should be doing better with fentanyl.”

Nicotine patches can also be dangerous to children, he added. As for other topical agents, there have been reports of toxicity and deaths linked to salicylic acid, commonly used by dermatologists because of its bacteriostatic, fungicidal, keratolytic, and photoprotective properties.

Dr. Schachner cited the case of a 2-month-old where the pediatrician prescribed 50% salicylic acid for seborrheic dermatitis of the scalp, under occlusion. “It’s amazing this child survived; that’s clearly a physician error,” he said.

Henna, a reddish-brown dye derived from the crushed leaves of Lawsonia alba, is used cosmetically for the hair, skin, and nails. Many henna products are mixed with additives, including para-phenylenediamine, which has been associated with dermatitis, asthma, renal failure, and permanent vision loss.

Asked to comment on the presentation, Sheilagh Maguiness, MD, professor of dermatology and pediatrics and chair of pediatric dermatology at the University of Minnesota, Minneapolis, recalled a particularly concerning story in 2008, when the FDA issued a warning about Mommy’s Bliss, a cream containing chlorphenesin and phenoxyethanol as preservatives, promoted to nursing mothers for soothing cracked nipples. There were reports of the cream causing respiratory distress, vomiting, and diarrhea in nursing infants.

Dr. Schachner is chair of Stiefel Laboratories and is an investigator with: Astellas, Berg Pharma, Celgene, Ferndale Labs, Lilly, Medimetriks Pharmaceuticals, Novartis, Organogenesis, Pfizer, Sciton; is a consultant for: Alphyn, Amryt Pharma, Beiersdorf, Brickell, Cutanea, Hoth, Lexington, Mustela, TopMD, Noble Pharma; a speaker for: Novartis, Sanofi-Regeneron, CeraVe; is on the advisory boards of: Almirall, Alphyn, Apogee, Aslan, Biofrontera, CeraVe, Krystal Biotech, Mustela, Noble Pharma, Pfizer, Pierre Fabre, Sanofi-Regeneron; and owns stocks in: TopMD and Alphyn. Dr. Maguiness had no relevant conflicts of interest.

PHILADELPHIA – Drinking more than three cups of coffee a day is linked to more rapid cognitive decline over time, results from a large study suggest.

Investigators examined the impact of different amounts of coffee and tea on fluid intelligence — a measure of cognitive functions including abstract reasoning, pattern recognition, and logical thinking.

“It’s the old adage that too much of anything isn’t good. It’s all about balance, so moderate coffee consumption is okay but too much is probably not recommended,” said study investigator Kelsey R. Sewell, PhD, Advent Health Research Institute, Orlando, Florida. 

The findings of the study were presented at the 2024 Alzheimer’s Association International Conference (AAIC).
 

One of the World’s Most Widely Consumed Beverages

Coffee is one of the most widely consumed beverages around the world. The beans contain a range of bioactive compounds, including caffeine, chlorogenic acid, and small amounts of vitamins and minerals.

Consistent evidence from observational and epidemiologic studies indicates that intake of both coffee and tea has beneficial effects on stroke, heart failure, cancers, diabetes, and Parkinson’s disease.  

Several studies also suggest that coffee may reduce the risk for Alzheimer’s disease, said Dr. Sewell. However, there are limited longitudinal data on associations between coffee and tea intake and cognitive decline, particularly in distinct cognitive domains.

Dr. Sewell’s group previously published a study of cognitively unimpaired older adults that found greater coffee consumption was associated with slower cognitive decline and slower accumulation of brain beta-amyloid.

Their current study extends some of the prior findings and investigates the relationship between both coffee and tea intake and cognitive decline over time in a larger sample of older adults.

This new study included 8451 mostly female (60%) and White (97%) cognitively unimpaired adults older than 60 (mean age, 67.8 years) in the UK Biobank, a large-scale research resource containing in-depth, deidentified genetic and health information from half a million UK participants. Study subjects had a mean body mass index (BMI) of 26, and about 26% were apolipoprotein epsilon 4 (APOE e4) gene carriers.

Researchers divided coffee and tea consumption into tertiles: high, moderate, and no consumption.

For daily coffee consumption, 18% reported drinking four or more cups (high consumption), 58% reported drinking one to three cups (moderate consumption), and 25% reported that they never drink coffee. For daily tea consumption, 47% reported drinking four or more cups (high consumption), 38% reported drinking one to three cups (moderate consumption), and 15% reported that they never drink tea.

The study assessed cognitive function at baseline and at least two additional patient visits. 

Researchers used linear mixed models to assess the relationships between coffee and tea intake and cognitive outcomes. The models adjusted for age, sex, Townsend deprivation index (reflecting socioeconomic status), ethnicity, APOE e4 status, and BMI.
 

Steeper Decline 

Compared with high coffee consumption (four or more cups daily), people who never consumed coffee (beta, 0.06; standard error [SE], 0.02; P = .005) and those with moderate consumption (beta, 0.07; SE, 0.02; P = < .001) had slower decline in fluid intelligence after an average of 8.83 years of follow-up.

“We can see that those with high coffee consumption showed the steepest decline in fluid intelligence across the follow up, compared to those with moderate coffee consumption and those never consuming coffee,” said Dr. Sewell, referring to illustrative graphs.

At the same time, “our data suggest that across this time period, moderate coffee consumption can serve as some kind of protective factor against cognitive decline,” she added.

For tea, there was a somewhat different pattern. People who never drank tea had a greater decline in fluid intelligence, compared with those who had moderate consumption (beta, 0.06; SE, 0.02; P = .0090) or high consumption (beta, 0.06; SE, 0.02; P = .003).

Because this is an observational study, “we still need randomized controlled trials to better understand the neuroprotective mechanism of coffee and tea compounds,” said Dr. Sewell.

Responding later to a query from a meeting delegate about how moderate coffee drinking could be protective, Dr. Sewell said there are probably “different levels of mechanisms,” including at the molecular level (possibly involving amyloid toxicity) and the behavioral level (possibly involving sleep patterns).

Dr. Sewell said that she hopes this line of investigation will lead to new avenues of research in preventive strategies for Alzheimer’s disease. 

“We hope that coffee and tea intake could contribute to the development of a safe and inexpensive strategy for delaying the onset and reducing the incidence for Alzheimer’s disease.”

A limitation of the study is possible recall bias, because coffee and tea consumption were self-reported. However, this may not be much of an issue because coffee and tea consumption “is usually quite a habitual behavior,” said Dr. Sewell.

The study also had no data on midlife coffee or tea consumption and did not compare the effect of different preparation methods or types of coffee and tea — for example, green tea versus black tea. 

When asked if the study controlled for smoking, Dr. Sewell said it didn’t but added that it would be interesting to explore its impact on cognition.

Dr. Sewell reported no relevant conflicts of interest.

TOPLINE:

People with knee osteoarthritis and symptoms for less than 1 year benefit more from exercise therapy than do those with longer symptom duration, especially when long-term outcomes are considered.

METHODOLOGY:

• Researchers conducted an individual participant data meta-analysis using data from the OA Trial Bank, including 1769 participants (mean age, 65.1 years; 66% women) with knee osteoarthritis from 10 randomized controlled trials.
• The participants were categorized on the basis of their symptom duration: ≤ 1 year, > 1 and ≤ 2 years, and > 2 years.
• This study included an exercise therapy group comprising land- and water-based therapeutic exercise interventions and a control group comprising no exercise or sham treatment.
• The primary outcomes were self-reported pain and physical function, standardized to a 0-100 scale, at short-term (closest to 3 months) and long-term (closest to 12 months) follow-ups.

TAKEAWAY:

• The overall pain and physical function associated with osteoarthritis improved in the exercise therapy group at both short- and long-term follow-ups compared with in the control group.
• Exercise therapy led to a greater improvement in short-term (mean difference [MD], −3.57; P = .028) and long-term (MD, −8.33; P < .001) pain among participants with a symptom duration ≤ 1 year vs > 1 year.
• Similarly, those with a symptom duration ≤ 2 years vs > 2 years who underwent exercise therapy showed greater benefits in terms of short-term (P = .001) and long-term (P < .001) pain.
• Exercise therapy improved long-term physical function in those with a symptom duration ≤ 1 year vs > 1 year (MD, −5.46; P = .005) and ≤ 2 years vs > 2 years (MD, −4.56; P = .001).

IN PRACTICE:

“Exercise should be encouraged as early as possible once symptoms emerge in the disease process to take advantage of its effects in potentially [slowing] disease progression within the suggested ‘window of opportunity,’ ” the authors wrote.

SOURCE:

The study was led by Marienke van Middelkoop, PhD, Erasmus MC Medical University, Rotterdam, the Netherlands. It was published online in Osteoarthritis and Cartilage.

LIMITATIONS:

The dataset of most studies included in the meta-analysis lacked information on the radiographic severity of osteoarthritis. The relatively short follow-up time hindered interpreting the impact of exercise on the long-term progression of osteoarthritis. The reliance on patient recall for recording symptom duration may have led to misclassification.

DISCLOSURES:

The Netherlands Organisation for Health Research and Development supported this study. Three authors received funding from the Dutch Arthritis Society for the program grant Center of Excellence “OA prevention and early treatment – OA Pearl.” One author declared receiving royalties for the UpToDate knee osteoarthritis clinical guidelines.

The Food and Drug Administration (FDA) has approved daratumumab and hyaluronidase-fihj (Darzalex Faspro, Janssen Research and Development) in combination with bortezomib, lenalidomide, and dexamethasone for induction and consolidation in transplant-eligible patients with newly diagnosed multiple myeloma.

Approval followed priority review and was based on efficacy and safety findings from the open-label PERSEUS trial involving 709 patients under age 70 years who were randomized to receive bortezomib, lenalidomide, and dexamethasone alone or in combination with daratumumab and hyaluronidase-fihj, according to the FDA. 

Compared with bortezomib, lenalidomide, and dexamethasone alone, the addition of daratumumab and hyaluronidase-fihj resulted in a 60% reduction in the risk for disease progression or death (hazard ratio, 0.40). Median progression-free survival was not reached in either group.

Adverse reactions occurring in ≥ 20% of patients were peripheral neuropathy, fatigue, edema, pyrexia, upper respiratory infection, constipation, diarrhea, musculoskeletal pain, insomnia, and rash. 

The recommended dosage for this indication is 1800 mg daratumumab and 30,000 units hyaluronidase, according to the full prescribing information.

Daratumumab and hyaluronidase-fihj, which was first approved in 2020, has a range of other indications in multiple myeloma.
