COPD Highlights From ATS 2024
The latest research on treatment of patients with COPD presented at the American Thoracic Society (ATS) 2024 annual meeting is reported on by Diego J. Maselli, MD, FCCP, CHEST Physician Editorial Board Member, from UT Health San Antonio in Texas.
Dr. Maselli discusses the phase 2a COURSE study, which looked at patients with moderate to severe COPD to determine whether novel tezepelumab would help reduce exacerbations over 52 weeks. The study reached a nonsignificant numerical reduction in the annual rate vs placebo, but Dr. Maselli suggests that outcomes in patients. with high blood eosinophil counts merit further study.
Next, Dr. Maselli discusses the phase 3 NOTUS trial, looking at the efficacy and safety of the monoclonal antibody dupilumab in patients with moderate to severe COPD. The researchers found a 34% reduction in exacerbations in the dupilumab group vs placebo after 52 weeks.
He then details a 272-patient study looking at nebulized ensifentrine, a dual inhibitor of PDE3 and PDE4. The study demonstrated improved lung function as well as a reduction in exacerbation rate to patients with moderate to severe COPD treated with ensifentrined added to long-acting beta agonists-inhaled corticosteroid maintenance therapy.
Finally, Dr. Maselli highlights the MAZI study, a large retrospective analysis comparing the mortality rate in patients with COPD taking single-inhaler triple therapy (SITT) vs multiple-inhaler triple therapy (MITT). The researchers found that SITT was superior to MITT.

Narcolepsy an Independent Cardiovascular Disease Risk Factor
HOUSTON — Narcolepsy is associated with a significantly increased risk for cardiovascular disease (CVD) and major adverse cardiac events (MACEs), independent of common comorbid conditions and medications commonly used to treat the chronic sleep disorder, according to two new studies.
A nationwide analysis revealed that people with narcolepsy had a 77% higher risk for CVD and an 82% higher risk for MACE than those without the disorder.
“These findings indicate that it is important for clinicians to regularly monitor patients for cardiovascular disease and take this into consideration when recommending specific treatments for narcolepsy,” study investigators Christopher Kaufmann, PhD; Munaza Riaz, PharmD, MPhil; and Rakesh Bhattacharjee, MD, told this news organization.
“Additionally, physicians should consider monitoring the presence of other health conditions as contributing factors to the risk of CVD,” they said. Dr. Kaufmann and Dr. Riaz are with the University of Florida, Gainesville, Florida, and Dr. Bhattacharjee is with the University of California, San Diego.
They presented their research at SLEEP 2024: 38th Annual Meeting of the Associated Professional Sleep Societies.
Independent Risk Factor
The National Institute of Neurological Disorders and Stroke reports an estimated 125,000 to 200,000 people in the United States live with narcolepsy. The condition often coexists with other common health conditions including obstructive sleep apnea (OSA), diabetes, and other comorbidities, which can all contribute to the risk for CVD.
This raises doubt as to whether narcolepsy itself directly leads to CVD or if it is the result of these comorbid health conditions. Additionally, some medications used to treat narcolepsy carry their own cardiovascular risks.
Using the IBM MarketScan Commercial and Medicare supplemental databases, the researchers identified 34,562 adults with a diagnosis of narcolepsy and a propensity-matched comparison cohort of 100,405 adults without narcolepsy. The patients had a mean age of 40 years, and 62% were women.
Compared with adults without narcolepsy, those with the chronic sleep disorder that causes overwhelming daytime drowsiness had a 77% increased risk for any CVD (hazard ratio [HR], 1.77) and an 82% increased risk for MACE (HR, 1.82).
They also had an increased risk for stroke (HR, 2.04), heart failure or myocardial infarction (MI; HR, 1.64), and atrial fibrillation (HR, 1.58).
The results were similar in a separate analysis of the same population that also controlled for baseline use of stimulants, oxybates, and wake-promoting agents — medications commonly used to treat excessive daytime sleepiness associated with narcolepsy.
In this analysis, narcolepsy was associated with an 89% higher risk for CVD (HR, 1.89) and a 95% increased risk for MACE (HR, 1.95). The risk for any stroke (HR, 2.06), heart failure (HR, 1.90), atrial fibrillation (HR, 1.66), and MI (HR, 1.93) was also higher in those with narcolepsy.
“Our study found that even after considering the presence of health conditions like obstructive sleep apnea, diabetes, hypertension, hyperlipidemia, and even depression, as well as medication use, there still appears to be an independent relationship between narcolepsy and CVD,” the investigators said.
They cautioned that the mechanisms explaining the link between CVD and narcolepsy are unclear and warrant further study.
“Sleep fragmentation is a hallmark of narcolepsy, and it is speculated that this fragmentation, which may trigger disturbances in autonomic function, predisposes individuals to CVD. In rodent models, a possible link has been observed between hypocretin — a central neurotransmitter that is reduced or deficient in patients with narcolepsy — and atherosclerosis.
“However, it remains uncertain whether this is the primary mechanism related to CVD,” they commented.
Compelling Evidence for Higher CVD
Commenting on the findings for this news organization, Shaheen Lakhan, MD, a neurologist and researcher based in Miami, Florida, called for narcolepsy to be recognized as a significant contributor to higher CVD risk.
“Given the compelling evidence linking narcolepsy to a higher incidence of cardiovascular disease, it is crucial that narcolepsy be included in clinical guidelines and risk assessment tools alongside other known risk factors,” said Dr. Lakhan, who was not involved in this research.
“Physicians and health care providers should proactively address the increased cardiovascular risk associated with narcolepsy by incorporating preventive strategies and interventions into the management of patients with this condition,” Dr. Lakhan suggested.
Regular CVD screening, a healthier lifestyle, and targeted therapies could all decrease cardiac risk, Dr. Lakhan added.
“Ultimately, novel disease-modifying therapies for narcolepsy should target the core mechanisms driving the increased cardiovascular risk associated with this condition. By elucidating the specific biological pathways and developing targeted therapies that address the unique challenges faced by narcolepsy patients, we can effectively mitigate the risk,” Dr. Lakhan said.
The studies were funded by the Sleep Research Society Foundation. The authors and Dr. Lakhan had no relevant disclosures.

Helping Patients Cut Down on Sodium: Useful Substitutes and Strategies
Humans have used salt for centuries, to preserve or cure food before refrigeration was readily available, and even as currency in some cultures. Though modern food preservation efforts have decreased our reliance on salt, we still heavily incorporate it as a flavor enhancer.
It’s only relatively recently that we’ve begun limiting salt in our diets, as research has linked high sodium intake with chronic, preventable conditions like hypertension, heart disease, and kidney disease.
How to Recommend Restriction in a Helpful Way
The US Department of Agriculture’s Dietary Guidelines for Americans recommends intake of no more than 2300 mg of sodium daily for adults and children aged 14 years or older. This echoes similar recommendations for people at risk for heart disease, kidney disease, and hypertension. However, the sodium intake of the average American still sits at a whopping 3400 mg daily.
High sodium intake is primarily the result of modern commercial food processing. Food prepared outside the home accounts for up to 70% of sodium intake in the United States, whereas only about 10% comes from salt that is added to food either during or after cooking. For this reason, I hesitate to recommend withholding salt as a primary focus when counseling on a low-sodium diet.
To many people, certain foods just taste better with salt. Many of my patients in the southern United States simply will not eat foods like eggs and tomatoes if they cannot salt them. We can spend every moment of patient interaction time explaining why excess sodium is unhealthy, but the fact remains that humans prefer food that tastes good. This is why I try to avoid counseling a “no-added-salt” diet; instead, I recommend a low-sodium diet with a focus on fresh, whole foods and limiting salt to only a few food items.
Patients should be counseled to slowly restrict their salt intake and be made aware that doing so may increase the time it takes for their sensitivity to the taste of less salty foods to return. But it is also important for them to know that it will return. The surest way to kill progress is for an unprepared patient to believe that their food will taste bland forever. A prepared patient understands that their food may taste different for a couple of weeks, but that the change will not last forever.
Types of Salt
I have often worked with patients who insist that their sodium intake is acceptable because they are using sea salt instead of table salt. This is the result of exceptional marketing and misinformation.
Specialty salts like sea salt and Himalayan pink salt contain about 560 mg and 590 mg of sodium, respectively, per quarter teaspoon. These products do have a slightly different mineral content, with sea salt typically having a negligible amount of calcium, magnesium, or potassium. The very small amount of these minerals offers no obvious health benefits compared with more affordable table salt.
The sodium content of iodized table salt is comparable to these products, with about 590 mg of sodium per quarter teaspoon. Though its high sodium content will put some practitioners off, it is also an excellent source of iodine, at about 75 mg per serving. It has been estimated that upward of 35% of the US population has iodine deficiency, most commonly due to pregnancy, avoidance of dairy products, increasing rates of vegetarianism, intake of highly processed foods, and avoidance of added salt. For this reason, and its relative affordability, I find table salt to be far more appropriate for the average American than specialty salts.
Salt Substitutes
Monosodium glutamate (MSG). MSG was previously at the center of public health concern owing to reports of “Chinese restaurant syndrome” that have since been debunked. I often recommend MSG to people trying to decrease sodium intake because the US Food and Drug Administration has designated it as GRAS (“generally recognized as safe”), and it has about one quarter of the sodium content of table salt at 125 mg per quarter teaspoon. Its crystalline structure makes it a lower-sodium salt substitute in savory applications like soups, stews, and gravies.
Hot sauce. These sauces are generally composed of peppers, vinegar, salt, and sugar. There may be some variation and occasionally added ingredients depending upon the brand. However, I find most hot sauces to be a low-sodium seasoning option that works especially well on proteins like eggs, chicken, and pork.
Potassium-based substitutes. Salt alternatives such as Nu-Salt and Morton Salt Substitute are sodium-free options with a significant amount of potassium, at 525 mg per quarter-teaspoon serving. These alternatives may not be ideal for patients with kidney problems, but they can be very helpful for those with potassium deficiency.
Herb-based seasonings. Garlic and onion powder are both sodium-free seasonings that many of my patients have found help to increase palatability while decreasing salt use. Black pepper; lemon and lime juice; salt-free herb mixes like Mrs. Dash; and spices like cumin, paprika, dill, chili powder, and ginger are also sodium-free or low-sodium alternatives that can help to alleviate blandness for someone new to a low-sodium diet. I recommend them often and use them in my own cooking at home.
Plant-based diet. If the goal of care is to improve cardiovascular or kidney health, then I find that working with patients to increase intake of plant foods to be a helpful option. This way of eating encourages replacing highly processed foods that may be high in sodium and sugar with plants that tend to be higher in potassium and calcium. The Dietary Approaches to Stop Hypertension (DASH), Mediterranean, and other plant-based diets have been shown to increase cardiovascular and metabolic health by significantly decreasing serum lipids, blood pressure, and hemoglobin A1c and promoting weight loss. They have also been shown to increase the gut microbiome and promote increased cognitive function.
I rarely encourage the use of added salt. However, research shows that putting down the salt shaker is probably not the most effective option to restrict sodium intake. For those who can cut back, these options can help keep food flavorful and patients compliant.

The very small amount of these minerals offers no obvious health benefits compared with more affordable table salt.
The sodium content of iodized table salt is comparable to these products, with about 590 mg of sodium per quarter teaspoon. Though its high sodium content will put some practitioners off, it is also an excellent source of iodine, at about 75 mg per serving. It has been estimated that upward of 35% of the US population has iodine deficiency, most commonly due to pregnancy, avoidance of dairy products, increasing rates of vegetarianism, intake of highly processed foods, and avoidance of added salt. For this reason, and its relative affordability, I find table salt to be far more appropriate for the average American than specialty salts.
Salt Substitutes
Monosodium glutamate (MSG). MSG was previously at the center of public health concern owing to reports of “Chinese restaurant syndrome” that have since been debunked. I often recommend MSG to people trying to decrease sodium intake because the US Food and Drug Administration has designated it as GRAS (“generally recognized as safe”), and it has about one quarter of the sodium content of table salt at 125 mg per quarter teaspoon. Its crystalline structure makes it a lower-sodium salt substitute in savory applications like soups, stews, and gravies.
Hot sauce. These sauces are generally composed of peppers, vinegar, salt, and sugar. There may be some variation and occasionally added ingredients depending upon the brand. However, I find most hot sauces to be a low-sodium seasoning option that works especially well on proteins like eggs, chicken, and pork.
Potassium-based substitutes. Salt alternatives such as Nu-Salt and Morton Salt Substitute are sodium-free options with a significant amount of potassium, at 525 mg per quarter-teaspoon serving. These alternatives may not be ideal for patients with kidney problems, but they can be very helpful for those with potassium deficiency.
Herb-based seasonings. Garlic and onion powder are both sodium-free seasonings that many of my patients have found help to increase palatability while decreasing salt use. Black pepper; lemon and lime juice; salt-free herb mixes like Mrs. Dash; and spices like cumin, paprika, dill, chili powder, and ginger are also sodium-free or low-sodium alternatives that can help to alleviate blandness for someone new to a low-sodium diet. I recommend them often and use them in my own cooking at home.
Plant-based diet. If the goal of care is to improve cardiovascular or kidney health, then I find that working with patients to increase intake of plant foods to be a helpful option. This way of eating encourages replacing highly processed foods that may be high in sodium and sugar with plants that tend to be higher in potassium and calcium. The Dietary Approaches to Stop Hypertension (DASH), Mediterranean, and other plant-based diets have been shown to increase cardiovascular and metabolic health by significantly decreasing serum lipids, blood pressure, and hemoglobin A1c and promoting weight loss. They have also been shown to increase the gut microbiome and promote increased cognitive function.
I rarely encourage the use of added salt. However, research shows that putting down the salt shaker is probably not the most effective option to restrict sodium intake. For those who can cut back, these options can help keep food flavorful and patients compliant.

Myeloma: VRd Plus Isatuximab Improves Outcomes
Patients who took isatuximab (Sarclisa) plus bortezomib, lenalidomide, and dexamethasone (VRd) reached higher estimated progression-free survival at a median 59.7 months vs. those who took VRd alone (63.2% vs. 45.2%, respectively, 98.5% CI, hazard ratio [HR] = 0.60, P < .001), reported Thierry Facon, MD, professor of hematology at Lille University Hospital, France, and colleagues at the annual meeting of the American Society of Clinical Oncology in Chicago. The study was simultaneously published in The New England Journal of Medicine.
“The significant progression-free benefit observed with Sarclisa with combination therapy compared to VRd is important and encouraging for patients with newly diagnosed multiple myeloma,” Dr. Facon said in an interview. The findings demonstrated the VRd-isatuximab’s potential as “a first-in-class combination to address gaps in care for newly diagnosed multiple myeloma transplant-ineligible patients,” he said.
According to Dr. Facon, more than 180,000 people worldwide are diagnosed with MM each year, he said, making it the second-most common hematologic malignancy.
“There is a need for new frontline therapeutic options for all MM patients,” he said. “Effective frontline therapy has the potential to modify the course of the disease, which is a key outcome for transplant-ineligible patients who often face high rates of attrition in later lines of therapy.”
For the industry-funded IMROZ study, researchers recruited patients aged 18-80 at 93 sites in 21 nations from 2017-2019. All were ineligible for transplant due to comorbidities or being aged 65 or older. Exclusions included Eastern Cooperative Oncology Group (ECOG) performance status scores of more than 2.
The subjects were randomly assigned in a 3-to-2 ratio to isatuximab-VRd (n = 265) or VRd alone (n = 181) and received four induction cycles (6 weeks per cycle) followed by 4-week cycles of continuous treatment until disease progression, unacceptable adverse event, or other criteria for discontinuation. If progression occurred, patients could be switched from the VRd-only group to the isatuximab-VRd group.
The median age in both the isatuximab-VRd and VRd groups was 72. The percentages of women were 46.0% and 48.1%, respectively, and 72.5% and 72.4%, respectively, were White. The next largest race/ethnic group was Asian (11.7% and 9.4%, respectively). Almost all had ECOG status of 0 or 1 (88.7% and 89.5%, respectively).
At study cut-off in September 2023, the percentages of subjects in the isatuximab-VRd and VRd groups who were still receiving treatment were 47.2% and 24.3%, respectively.
An intention-to-treat analysis found that the two groups had similar rates of overall response (91.3% for isatuximab-VRd vs. 92.3% for VRd), but the isatuximab-VRd group had higher complete or better response (74.7% vs. 64.1%, P = .01).
The percentage of patients who were minimal residual disease (MRD)-negative and had a complete response was also higher in the VRd-isatuximab group vs. the VRd group (55.5% vs. 40.9%, respectively, P = .003). A total of 26.0% of patients in the VRd-isatuximab group died vs. 32.6% in the VRd group; the estimated overall survival rates at 60 months were 72.3% and 66.3%, respectively, HR = 0.78, 99.97% CI).
As for adverse events, grade 5 events were more common in the VRd-isatuximab group (11.0% vs. 5.5%), as were deaths within the first 60 days of treatment (1.5% vs. 0.6%). “The difference was driven in part by different treatment exposures,” the researchers reported. Treatment-emergent events led to treatment discontinuation in 22.8% and 26.0% of patients, respectively.
“The safety and tolerability of Sarclisa observed was consistent with the established safety profile of Sarclisa and VRd with no new safety signals observed,” Dr. Facon said.
In an interview, Zandra Klippel, MD, global product head for multiple myeloma at Sanofi — the maker of isatuximab and funder of the study — said the Food and Drug Administration has accepted a priority review application for the investigational use of isatuximab in combination with VRd for the treatment of patients with transplant-ineligible, newly diagnosed MM.
“Our FDA approval date is expected on September 27, 2024,” Dr. Klippel said. “If all goes well, we anticipate launching as early as 2024 in the US and rolling out in other key countries starting in 2025 and continuing through 2026.”
Dr. Klippel added that isatuximab “continues to be evaluated in multiple ongoing phase 3 clinical trials in combination with current standard treatments across the MM treatment continuum.”
In an interview, Sagar Lonial, MD, chair and professor of hematology and medical oncology and chief medical officer at Winship Cancer Institute at Emory University in Atlanta, said the study is “important.”
However, Dr. Lonial, who is familiar with the findings but didn’t take part in the study, said it’s difficult to understand the impact of the treatment on frail patients. It appears that the combination treatment may be good for frail patients, he said, “but I need to better understand the magnitude of the benefit in that subset a little more.”
As for adverse events, he said “they are what would be expected for a trial like this.”
Pneumonia and COVID-19 infections were higher in the VRd-isatuximab group, he said, and “we know in general that vaccine responses are blocked by CD38 antibodies.” This can be managed, he said, via intravenous immunoglobulin support.
Manni Mohyuddin, MD, assistant professor at Huntsman Cancer Institute in Utah, said in an interview that the findings suggest that in older, fit patients, “you can get fairly good outcomes without use of transplant.”
In the United States, many more patients in the cohort would have been considered transplant-eligible, he said, and not eliminated from consideration for transplant due to age over 65. However, as patients age, “you get more diminishing returns for transplants,” said Dr. Mohyuddin, who is familiar with the study findings but didn’t take part in the research.
All the drugs in the new combination are FDA approved, he said, although the combination isn’t. “I suspect this will make it to our guidelines very soon and then be reimbursed by insurance companies and Medicare.”
The study was funded by Sanofi and an M.D. Anderson Cancer Center support grant. Dr. Facon has no disclosures. Other study authors report multiple ties relationships with various drug makers. Dr. Lonial disclosed ties with Takeda, Amgen, Novartis, BMS, GSK, AbbVie, Genentech, Pfizer, Regeneron, Janssen, AstraZeneca, and TG Therapeutics).

FROM ASCO 2024
Melatonin May Cut Risk for Age-Related Eye Disease
TOPLINE:
Melatonin supplementation is linked to a reduced risk for developing age-related macular degeneration (AMD) and slowing its progression, suggesting potential as a preventive therapy.
METHODOLOGY:
- Researchers analyzed data from the TriNetX database, covering electronic medical records across the United States from December 2023 to March 2024.
- The retrospective study included patients aged ≥ 50 years, divided into groups based on their history of AMD and melatonin medication codes between November 2008 and November 2023.
- Propensity score matching was used to compare melatonin users and nonusers for the risk for developing any form of AMD or the progression to exudative AMD from the nonexudative form of the condition.
TAKEAWAY:
- Use of melatonin was associated with a 58% reduction in the risk for developing AMD, according to the researchers.
- In people with nonexudative AMD, use of the supplement was linked to a 56% lower risk for progression to exudative AMD.
- The findings were consistent across age groups, suggesting melatonin’s benefits may extend to older populations at higher risk for AMD, the researchers reported.
IN PRACTICE:
“In this cohort study of 121,523 patients with no history of AMD aged ≥ 50 years, taking melatonin was associated with a decreased risk of developing AMD,” the authors of the study wrote. “Likewise, among 66,253 patients with preexisting nonexudative AMD, melatonin supplementation was negatively associated with the rate of progression to exudative AMD.”
Studies in animals and humans have shown melatonin may be a potent antioxidant and anti-inflammatory agent and have both antiangiogenic and mitochondrial-preserving properties, the authors noted. The new findings “provide a rationale for expanding clinical research on the potential therapeutic efficacy of melatonin in preventing AMD development or its progression,” they added.
SOURCE:
The study was led by Hejin Jeong, Case Western Reserve University School of Medicine, Cleveland, and was published online in JAMA Ophthalmology.
LIMITATIONS:
The study’s reliance on diagnostic codes may have limited the accuracy of identifying AMD progression. Variations in coding practices and the reporting of over-the-counter medications like melatonin could have influenced the results. The study did not control for all modifiable risk factors for AMD, which may have introduced healthy user bias.
DISCLOSURES:
The authors reported various potential conflicts of interest, including receiving personal fees and grants from various pharmaceutical companies. The study was funded by grants from the National Institutes of Health and the Cleveland Eye Bank Foundation.
This article was created using several editorial tools, including AI, as part of the process. Human editors reviewed this content before publication.

SCD: Delaying Transition to Adult Care Poses Risks
TOPLINE:
METHODOLOGY:
- Guidelines have recommended that young adults with SCD transfer from pediatric care within 6 months, but many transfers take longer — sometimes up to a year.
- Researchers evaluated the impact of prolonged transition gaps on health outcomes in 183 young adults who completed pediatric care between 2012 and 2018 and were transitioned to an adult care program. Patients were followed for 2-8 years from their first adult care visit.
TAKEAWAY:
- Approximately 88% of patients transferred to adult health care within 6 months, with a median transfer gap of 1.4 months. At 2 years of adult care, patients with a transition gap of 6 months or longer were 89% (relative risk, 1.89) more likely to have an inpatient visit and 75% (RR, 1.75) more likely to have ED visits.
- Those with transfer gaps of 6 months or longer had twice the rate of inpatient visits (rate ratio, 2.01) at 8 years of follow-up, compared with those who transitioned within 2 months.
- However, fewer adult care outpatient visits were seen (5.1 vs 6.7 visits per year) for young adults transferred in 6 or more months versus those within 6 months.
IN PRACTICE:
According to the authors, “longer delays in establishing adult health care following pediatric care were associated with greater acute health care resource utilization and fewer health care maintenance (ie, outpatient) SCD visits. These findings emphasize the importance of swift transfer from pediatric to adult care among young adults with SCD.”
SOURCE:
The study was led by Kristen E. Howell, of the Department of Epidemiology and Biostatistics, Texas A&M School of Public Health, College Station, Texas, and was published online in Blood Advances.
LIMITATIONS:
Data was available only for patients within a specific health care system, limiting the generalizability of the findings. Involving only one pediatric and two adult programs could impact findings. Insurance loss or changes due to low income were not accounted for.
DISCLOSURES:
The study was funded by U1EMC19331 and the American Lebanese Syrian Associated Charities. The authors declared no relevant conflicts of interest.
TOPLINE:
METHODOLOGY:
- Guidelines have recommended that young adults with SCD transfer from pediatric care within 6 months, but many transfers take longer — sometimes up to a year.
- Researchers evaluated the impact of prolonged transition gaps on health outcomes in 183 young adults who completed pediatric care between 2012 and 2018 and were transitioned to an adult care program. Patients were followed for 2-8 years from their first adult care visit.
TAKEAWAY:
- Approximately 88% of patients transferred to adult health care within 6 months, with a median transfer gap of 1.4 months. At 2 years of adult care, patients with a transition gap of 6 months or longer were 89% (relative risk, 1.89) more likely to have an inpatient visit and 75% (RR, 1.75) more likely to have ED visits.
- Those with transfer gaps of 6 months or longer had twice the rate of inpatient visits (rate ratio, 2.01) at 8 years of follow-up, compared with those who transitioned within 2 months.
- However, fewer adult care outpatient visits were seen (5.1 vs 6.7 visits per year) for young adults transferred in 6 or more months versus those within 6 months.

Erythematous Flaky Rash on the Toe
The Diagnosis: Necrolytic Migratory Erythema
Necrolytic migratory erythema (NME) is a waxing and waning rash associated with rare pancreatic neuroendocrine tumors called glucagonomas. It is characterized by pruritic and painful, well-demarcated, erythematous plaques that manifest in the intertriginous areas and on the perineum and buttocks.1 Due to the evolving nature of the rash, the histopathologic findings in NME vary depending on the stage of the cutaneous lesions at the time of biopsy.2 Multiple dyskeratotic keratinocytes spanning all epidermal layers may be a diagnostic clue in early lesions of NME.3 Typical features of longstanding lesions include confluent parakeratosis, psoriasiform hyperplasia with mild or absent spongiosis, and upper epidermal necrosis with keratinocyte vacuolization and pallor.4 Morphologic features that are present prior to the development of epidermal vacuolation and necrosis frequently are misattributed to psoriasis or eczema. Long-standing lesions also may develop a neutrophilic infiltrate with subcorneal and intraepidermal pustules.2 Other common features include a discrete perivascular lymphocytic infiltrate and an erosive or encrusted epidermis.5 Although direct immunofluorescence typically is negative, nonspecific findings can be seen, including apoptotic keratinocytes labeling with fibrinogen and C3, as well as scattered, clumped, IgM-positive cytoid bodies present at the dermal-epidermal junction (DEJ).6 Biopsies also have shown scattered, clumped, IgM-positive cytoid bodies present at the DEJ.5
Psoriasis is a chronic relapsing papulosquamous disorder characterized by scaly erythematous plaques often overlying the extensor surfaces of the extremities. Histopathology shows a psoriasiform pattern of inflammation with thinning of the suprapapillary plates and elongation of the rete ridges. Further diagnostic clues of psoriasis include regular acanthosis, characteristic Munro microabscesses with neutrophils in a hyperkeratotic stratum corneum (Figure 1), hypogranulosis, and neutrophilic spongiform pustules of Kogoj in the stratum spinosum. Generally, there is a lack of the epidermal necrosis seen with NME.7,8
Lichen simplex chronicus manifests as pruritic, often hyperpigmented, well-defined, lichenified plaques with excoriation following repetitive mechanical trauma, commonly on the lower lateral legs, posterior neck, and flexural areas.9 The histologic landscape is marked by well-developed lesions evolving to show compact orthokeratosis, hypergranulosis, irregularly elongated rete ridges (ie, irregular acanthosis), and papillary dermal fibrosis with vertical streaking of collagen (Figure 2).9,10
Subacute cutaneous lupus erythematosus (SCLE) is recognized clinically by scaly/psoriasiform and annular lesions with mild or absent systemic involvement. Common histopathologic findings include epidermal atrophy, vacuolar interface dermatitis with hydropic degeneration of the basal layer, a subepidermal lymphocytic infiltrate, and a periadnexal and perivascular infiltrate (Figure 3).11 Upper dermal edema, spotty necrosis of individual cells in the epidermis, dermal-epidermal separation caused by prominent basal cell degeneration, and accumulation of acid mucopolysaccharides (mucin) are other histologic features associated with SCLE.12,13
The immunofluorescence pattern in SCLE features dustlike particles of IgG deposition in the epidermis, subepidermal region, and dermal cellular infiltrate. Lesions also may have granular deposition of immunoreactions at the DEJ.11,13
The manifestation of drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome (also known as drug-induced hypersensitivity syndrome) is variable, with a morbilliform rash that spreads from the face to the entire body, urticaria, atypical target lesions, purpuriform lesions, lymphadenopathy, and exfoliative dermatitis.14 The nonspecific morphologic features of DRESS syndrome lesions are associated with variable histologic features, which include focal interface changes with vacuolar alteration of the basal layer; atypical lymphocytes with hyperchromic nuclei; and a superficial, inconsistently dense, perivascular lymphocytic infiltrate. Other relatively common histopathologic patterns include an upper dermis with dilated blood vessels, spongiosis with exocytosis of lymphocytes (Figure 4), and necrotic keratinocytes. Although peripheral eosinophilia is an important diagnostic criterion and is observed consistently, eosinophils are variably present on skin biopsy.15,16 Given the histopathologic variability and nonspecific findings, clinical correlation is required when diagnosing DRESS syndrome.

These findings suggest that restoring EEC function could alleviate some of the more general abdominal symptoms associated with IBD, reported lead author Zachariah Raouf, MD, of Johns Hopkins University School of Medicine, Baltimore, and colleagues.
“The symptoms experienced by patients with IBD, especially ulcerative colitis, may include those that are colonic in nature, such as bloody stools, abdominal pain, and weight loss, as well as those that are more general in nature, such as severe nausea and abdominal bloating,” the investigators wrote in Cellular and Molecular Gastroenterology and Hepatology . “Although the first set of symptoms may be attributable to the effects of colonic inflammation itself, those that are more vague seem to overlap with the symptoms that patients with small intestinal dysmotility experience, such as occur in response to medications, or diabetes.”
Supporting this notion, several previous studies have reported the onset of intestinal dysmotility in experimental models of colitis, which is believed to be caused by impaired enteric nervous system function. But the precise mechanisms behind the impaired intestinal motility observed in colitis patients remain unclear.
To learn more, Dr. Raouf and colleagues conducted experiments involving three groups of mice: wild-type mice, mice genetically engineered to overexpress EECs, and mice lacking EECs.
To induce colitis, the mice were administered dextran sulfate sodium (DSS) in drinking water at concentrations of 2.5% or 5% for 7 days. Small intestinal motility was evaluated by measuring the transit of fluorescein isothiocyanate (FITC)-dextran. Immunohistochemical analyses were conducted to assess EEC number and differentiation, while quantitative reverse-transcriptase polymerase chain reaction was used to examine the expression of genes related to serotonin synthesis and transport.
The researchers examined colon length and signs of colonic inflammation, monitored weight loss, and measured the expression of proinflammatory cytokines. Histological analyses of colon and small intestine tissues were performed to further understand the effects of colitis. The presence and number of EEC cells was evaluated using chromogranin A (ChgA) staining, while apoptosis in EECs was measured via TUNEL staining. The expression of serotonin-related genes was also assessed.
These experiments revealed that DSS-induced colitis led to significant small-bowel hypomotility and a reduction in EEC density. Of note, genetic overexpression of EECs or treatment with prucalopride, a 5-hydroxytryptamine receptor 4 agonist, improved small intestinal motility.
“It is noteworthy that there were no significant changes in the density of other intestinal epithelial cells, or in other cell types that are linked to motility, such as enteric glia and neurons, suggesting the specificity of the effect,” the investigators wrote. “Importantly, treatment with a serotonin agonist ameliorated the colitis-induced, small-bowel hypomotility and attenuated the severity of colitis, providing potential clinical relevance of the current findings. Taken together, these results identify mechanisms to explain the intestinal hypomotility observed in the setting of colitis.”Dr. Raouf and colleagues called for human clinical trials to their findings. Specifically, they suggested exploring therapies targeting enteroendocrine cells or serotonin pathways and examining the role of different EEC types in gut motility during inflammation. The study was supported by the National Institutes of Health. The investigators disclosed no conflicts of interest.
Inflammatory bowel disease (IBD) typically manifests with colonic symptoms but is also associated with intestinal inflammation and dysmotility of the small intestine. Clinical research debates whether IBD causes small intestine hypermotility or hypomotility, but these motility dysfunctions are often attributed to alterations of the gut’s intrinsic nervous system.
Dr. Raouf and colleagues focus on the role of enteroendocrine cells, an epithelial cell subtype with neuron-like features that secrete serotonin, one of the most important regulators of intestinal motility. Their population is reduced in colitis, and the subsequent alteration of serotonin signaling induces small intestine dysmotility. The observed loss of enteroendocrine cells in the small bowel may result from low-grade local inflammation increasing enteroendocrine cell apoptosis, or impaired gene expression in their differentiation pathways. However, more research is required to elucidate the underlying mechanisms of this loss.
This study enhances our understanding of the small intestine dysfunction associated with colitis and raises the exciting possibility of enteroendocrine cell-based therapeutic approaches in IBD.

Latest Breakthroughs in Molluscum Contagiosum Therapy
Molluscum contagiosum (ie, molluscum) is a ubiquitous infection caused by the poxvirus molluscum contagiosum virus (MCV). Although skin deep, molluscum shares many factors with the more virulent poxviridae. Moisture and trauma can cause viral material to be released from the pearly papules through a small opening, which also allows entry of bacteria and medications into the lesion. The MCV is transmitted by direct contact with skin or via fomites.1
Molluscum can affect children of any age, with MCV type 1 peaking in toddlers and school-aged children and MCV type 2 after the sexual debut. The prevalence of molluscum has increased since the 1980s. It is stressful for children and caregivers and poses challenges in schools as well as sports such as swimming, wrestling, and karate.1,2
For the first time, we have US Food and Drug Administration (FDA)–approved products to treat MCV infections. Previously, only off-label agents were used. Therefore, we have to contemplate why treatment is important to our patients.
What type of care is required for molluscum?
Counseling is the first and only mandatory treatment, which consists of 3 parts: natural history, risk factors for spread, and options for therapy. The natural history of molluscum in children is early spread, contagion to oneself and others (as high as 60% of sibling co-bathers3), triggering of dermatitis, eventual onset of the beginning-of-the-end (BOTE) sign, and eventually clearance. The natural history in adults is poorly understood.
Early clearance is uncommon; reports have suggested 45.6% to 48.4% of affected patients are clear at 1 year and 69.5% to 72.6% at 1.5 years.4 For many children, especially those with atopic dermatitis (AD), lesions linger and often spread, with many experiencing disease for 3 to 4 years. Fomites such as towels, washcloths, and sponges can transfer the virus and spread lesions; therefore, I advise patients to gently pat their skin dry, wash towels frequently, and avoid sharing bathing equipment.1,3,5 Children and adults with immunosuppression may have a greater number of lesions and more prolonged course of disease, including those with HIV as well as DOC8 and CARD11 mutations.6 The American Academy of Pediatrics (AAP) emphasizes that children should not be excluded from attending child care/school or from swimming in public pools but lesions should be covered.6 Lesions, especially those in the antecubital region, can trigger new-onset AD or AD flares.3 In response, gentle skin care including fragrance-free cleansers and periodic application of moisturizers may ward off AD. Topical corticosteroids are preferred.
Dermatitis in MCV is a great mimicker and can resemble erythema multiforme, Gianotti-Crosti syndrome, impetigo, and AD.1 Superinfection recently has been reported; however, in a retrospective analysis of 56 patients with inflamed lesions secondary to molluscum infection, only 7 had positive bacterial cultures, which supports the idea of the swelling and redness of inflammation as a mimic for infection.7 When true infection does occur, tender, swollen, pus-filled lesions should be lanced and cultured.1,7,8
When should we consider therapy?
Therapy is highly dependent on the child, the caregiver, and the social circumstances.1 More than 80% of parents are anxious about molluscum, and countless children are embarrassed or ashamed.1 Ultimately, an unhappy child merits care. The AAP cites the following as reasons to treat: “(1) alleviate discomfort, including itching; (2) reduce autoinoculation; (3) limit transmission of the virus to close contacts; (4) reduce cosmetic concerns; and (5) prevent secondary infection.”6 For adults, we should consider limitations to intimacy and reduction of sexual transmission risk.6
Treatment can be based on the number of lesions. With a few lesions (<3), therapy is worthwhile if they are unsightly; appear on exposed skin causing embarrassment; and/or are itchy, uncomfortable, or large. In a report of 300 children with molluscum treated with cantharidin, most patients choosing therapy had 10 to 20 lesions, but this was over multiple visits.8 Looking at a 2018 data set of 50 patients (all-comers) with molluscum,3 the mean number of lesions was 10 (median, 7); 3 lesions were 1 SD below, while 14, 17, and 45 were 1, 2, and 3 SDs above, respectively. This data set shows that patients can develop more lesions rapidly, and most children have many visible lesions (N.B. Silverberg, MD, unpublished data).
Because each lesion contains infectious viral particles and patients scratch, more lesions are equated to greater autoinoculation and contagion. In addition to the AAP criteria, treatment can be considered for households with immunocompromised individuals, children at risk for new-onset AD, or those with AD at risk for flare. For patients with 45 lesions or more (3 SDs), clearance is harder to achieve with 2 sessions of in-office therapy, and multiple methods or the addition of immunomodulatory therapeutics should be considered.
Do we have to clear every lesion?
New molluscum lesions may arise until a patient achieves immunity, and they may appear more than a month after inoculation, making it difficult to keep up with the rapid spread. Latency between exposure and lesion development usually is 2 to 7 weeks but may be as long as 6 months, making it difficult to prevent spread.6 Therefore, when we treat, we should not promise full clearance to patients and parents. Rather, we should inform them that new lesions may develop later, and therapy is only effective on visible lesions. In a recent study, a 50% clearance of lesions was the satisfactory threshold for parents, demonstrating that satisfaction is possible with partial clearance.9
What is new in therapeutics for molluscum?
Molluscum therapies are either destructive, immunomodulatory, or antiviral. Two agents now are approved by the FDA for the treatment of molluscum infections.
Berdazimer gel 10.3% is approved for patients 1 year or older, but it is not yet available. This agent has both immunomodulatory and antiviral properties.10 It features a home therapy that is mixed on a small palette, then painted on by the patient or parent once daily for 12 weeks. Study outcomes demonstrated more than 50% lesional clearance.11,12 Complete clearance was achieved in at least 30% of patients.12A proprietary topical version of cantharidin 0.7% in flexible collodion is now FDA approved for patients 2 years and older. This vesicant-triggering iatrogenic is targeted at creating blisters overlying molluscum lesions. It is conceptually similar to older versions but with some enhanced features.5,13,14 This version was used for therapy every 3 weeks for up to 4 sessions in clinical trials. Safety is similar across all body sites treated (nonmucosal and not near the mucosal surfaces) but not for mucosa, the mid face, or eyelids.13 Complete lesion clearance was 46.3% to 54% and statistically greater than placebo (P<.001).14Both agents are well tolerated in children with AD; adverse effects include blistering with cantharidin and dermatitislike symptoms with berdazimer.15,16 These therapies have the advantage of being easy to use.
Final Thoughts
We have entered an era of high-quality molluscum therapy. Patient care involves developing a good knowledge of the agents, incorporating shared decision-making with patients and caregivers, and addressing therapy in the context of comorbid diseases such as AD.

Fomites such as towels, washcloths, and sponges can transfer the virus and spread lesions; therefore, I advise patients to gently pat their skin dry, wash towels frequently, and avoid sharing bathing equipment.1,3,5 Children and adults with immunosuppression may have a greater number of lesions and more prolonged course of disease, including those with HIV as well as DOC8 and CARD11 mutations.6 The American Academy of Pediatrics (AAP) emphasizes that children should not be excluded from attending child care/school or from swimming in public pools but lesions should be covered.6 Lesions, especially those in the antecubital region, can trigger new-onset AD or AD flares.3 In response, gentle skin care including fragrance-free cleansers and periodic application of moisturizers may ward off AD. Topical corticosteroids are preferred.
Dermatitis in MCV is a great mimicker and can resemble erythema multiforme, Gianotti-Crosti syndrome, impetigo, and AD.1 Superinfection recently has been reported; however, in a retrospective analysis of 56 patients with inflamed lesions secondary to molluscum infection, only 7 had positive bacterial cultures, which supports the idea of the swelling and redness of inflammation as a mimic for infection.7 When true infection does occur, tender, swollen, pus-filled lesions should be lanced and cultured.1,7,8
When should we consider therapy?
Therapy is highly dependent on the child, the caregiver, and the social circumstances.1 More than 80% of parents are anxious about molluscum, and countless children are embarrassed or ashamed.1 Ultimately, an unhappy child merits care. The AAP cites the following as reasons to treat: “(1) alleviate discomfort, including itching; (2) reduce autoinoculation; (3) limit transmission of the virus to close contacts; (4) reduce cosmetic concerns; and (5) prevent secondary infection.”6 For adults, we should consider limitations to intimacy and reduction of sexual transmission risk.6
Treatment can be based on the number of lesions. With a few lesions (<3), therapy is worthwhile if they are unsightly; appear on exposed skin causing embarrassment; and/or are itchy, uncomfortable, or large. In a report of 300 children with molluscum treated with cantharidin, most patients choosing therapy had 10 to 20 lesions, but this was over multiple visits.8 Looking at a 2018 data set of 50 patients (all-comers) with molluscum,3 the mean number of lesions was 10 (median, 7); 3 lesions were 1 SD below, while 14, 17, and 45 were 1, 2, and 3 SDs above, respectively. This data set shows that patients can develop more lesions rapidly, and most children have many visible lesions (N.B. Silverberg, MD, unpublished data).
Because each lesion contains infectious viral particles and patients scratch, more lesions are equated to greater autoinoculation and contagion. In addition to the AAP criteria, treatment can be considered for households with immunocompromised individuals, children at risk for new-onset AD, or those with AD at risk for flare. For patients with 45 lesions or more (3 SDs), clearance is harder to achieve with 2 sessions of in-office therapy, and multiple methods or the addition of immunomodulatory therapeutics should be considered.
Do we have to clear every lesion?
New molluscum lesions may arise until a patient achieves immunity, and they may appear more than a month after inoculation, making it difficult to keep up with the rapid spread. Latency between exposure and lesion development usually is 2 to 7 weeks but may be as long as 6 months, making it difficult to prevent spread.6 Therefore, when we treat, we should not promise full clearance to patients and parents. Rather, we should inform them that new lesions may develop later, and therapy is only effective on visible lesions. In a recent study, a 50% clearance of lesions was the satisfactory threshold for parents, demonstrating that satisfaction is possible with partial clearance.9
What is new in therapeutics for molluscum?
Molluscum therapies are either destructive, immunomodulatory, or antiviral. Two agents now are approved by the FDA for the treatment of molluscum infections.
Berdazimer gel 10.3% is approved for patients 1 year or older, but it is not yet available. This agent has both immunomodulatory and antiviral properties.10 It features a home therapy that is mixed on a small palette, then painted on by the patient or parent once daily for 12 weeks. Study outcomes demonstrated more than 50% lesional clearance.11,12 Complete clearance was achieved in at least 30% of patients.12A proprietary topical version of cantharidin 0.7% in flexible collodion is now FDA approved for patients 2 years and older. This vesicant-triggering iatrogenic is targeted at creating blisters overlying molluscum lesions. It is conceptually similar to older versions but with some enhanced features.5,13,14 This version was used for therapy every 3 weeks for up to 4 sessions in clinical trials. Safety is similar across all body sites treated (nonmucosal and not near the mucosal surfaces) but not for mucosa, the mid face, or eyelids.13 Complete lesion clearance was 46.3% to 54% and statistically greater than placebo (P<.001).14Both agents are well tolerated in children with AD; adverse effects include blistering with cantharidin and dermatitislike symptoms with berdazimer.15,16 These therapies have the advantage of being easy to use.
Final Thoughts
We have entered an era of high-quality molluscum therapy. Patient care involves developing a good knowledge of the agents, incorporating shared decision-making with patients and caregivers, and addressing therapy in the context of comorbid diseases such as AD.

Chronotherapy: Why Timing Drugs to Our Body Clocks May Work
Do drugs work better if taken by the clock?
A new analysis published in The Lancet journal’s eClinicalMedicine suggests: Yes, they do — if you consider the patient’s individual body clock. The study is the first to find that timing blood pressure drugs to a person’s personal “chronotype” — that is, whether they are a night owl or an early bird — may reduce the risk for a heart attack.
The findings represent a significant advance in the field of circadian medicine or “chronotherapy” — timing drug administration to circadian rhythms. A growing stack of research suggests this approach could reduce side effects and improve the effectiveness of a wide range of therapies, including vaccines, cancer treatments, and drugs for depression, glaucoma, pain, seizures, and other conditions. Still, despite decades of research, time of day is rarely considered in writing prescriptions.
“We are really just at the beginning of an exciting new way of looking at patient care,” said Kenneth A. Dyar, PhD, whose lab at Helmholtz Zentrum München’s Institute for Diabetes and Cancer focuses on metabolic physiology. Dr. Dyar is co-lead author of the new blood pressure analysis.
“Chronotherapy is a rapidly growing field,” he said, “and I suspect we are soon going to see more and more studies focused on ‘personalized chronotherapy,’ not only in hypertension but also potentially in other clinical areas.”
The ‘Missing Piece’ in Chronotherapy Research
Blood pressure drugs have long been chronotherapy’s battleground. After all, blood pressure follows a circadian rhythm, peaking in the morning and dropping at night.
That healthy overnight dip can disappear in people with diabetes, kidney disease, and obstructive sleep apnea. Some physicians have suggested a bed-time dose to restore that dip. But studies have had mixed results, so “take at bedtime” has become a less common recommendation in recent years.
But the debate continued. After a large 2019 Spanish study found that bedtime doses had benefits so big that the results drew questions, an even larger, 2022 randomized, controlled trial from the University of Dundee in Dundee, Scotland — called the TIME study — aimed to settle the question.
Researchers assigned over 21,000 people to take morning or night hypertension drugs for several years and found no difference in cardiovascular outcomes.
“We did this study thinking nocturnal blood pressure tablets might be better,” said Thomas MacDonald, MD, professor emeritus of clinical pharmacology and pharmacoepidemiology at the University of Dundee and principal investigator for the TIME study and the recent chronotype analysis. “But there was no difference for heart attacks, strokes, or vascular death.”
So, the researchers then looked at participants’ chronotypes, sorting outcomes based on whether the participants were late-to-bed, late-to-rise “night owls” or early-to-bed, early-to-rise “morning larks.”
Their analysis of these 5358 TIME participants found the following results: Risk for hospitalization for a heart attack was at least 34% lower for “owls” who took their drugs at bedtime. By contrast, owls’ heart attack risk was at least 62% higher with morning doses. For “larks,” the opposite was true. Morning doses were associated with an 11% lower heart attack risk and night doses with an 11% higher risk, according to supplemental data.
The personalized approach could explain why some previous chronotherapy studies have failed to show a benefit. Those studies did not individualize drug timing as this one did. But personalization could be key to circadian medicine’s success.
“Our ‘internal personal time’ appears to be an important variable to consider when dosing antihypertensives,” said co-lead author Filippo Pigazzani, MD, PhD, clinical senior lecturer and honorary consultant cardiologist at the University of Dundee School of Medicine. “Chronotherapy research has been going on for decades. We knew there was something important with time of day. But researchers haven’t considered the internal time of individual people. I think that is the missing piece.”
The analysis has several important limitations, the researchers said. A total of 95% of participants were White. And it was an observational study, not a true randomized comparison. “We started it late in the original TIME study,” Dr. MacDonald said. “You could argue we were reporting on those who survived long enough to get into the analysis.” More research is needed, they concluded.
Looking Beyond Blood Pressure
What about the rest of the body? “Almost all the cells of our body contain ‘circadian clocks’ that are synchronized by daily environmental cues, including light-dark, activity-rest, and feeding-fasting cycles,” said Dr. Dyar.
An estimated 50% of prescription drugs hit targets in the body that have circadian patterns. So, experts suspect that syncing a drug with a person’s body clock might increase effectiveness of many drugs.
A handful of US Food and Drug Administration–approved drugs already have time-of-day recommendations on the label for effectiveness or to limit side effects, including bedtime or evening for the insomnia drug Ambien, the HIV antiviral Atripla, and cholesterol-lowering Zocor. Others are intended to be taken with or after your last meal of the day, such as the long-acting insulin Levemir and the cardiovascular drug Xarelto. A morning recommendation comes with the proton pump inhibitor Nexium and the attention-deficit/hyperactivity disorder drug Ritalin.
Interest is expanding. About one third of the papers published about chronotherapy in the past 25 years have come out in the past 5 years. The May 2024 meeting of the Society for Research on Biological Rhythms featured a day-long session aimed at bringing clinicians up to speed. An organization called the International Association of Circadian Health Clinics is trying to bring circadian medicine findings to clinicians and their patients and to support research.
Moreover, while recent research suggests minding the clock could have benefits for a wide range of treatments, ignoring it could cause problems.
In a Massachusetts Institute of Technology study published in April in Science Advances, researchers looked at engineered livers made from human donor cells and found more than 300 genes that operate on a circadian schedule, many with roles in drug metabolism. They also found that circadian patterns affected the toxicity of acetaminophen and atorvastatin. Identifying the time of day to take these drugs could maximize effectiveness and minimize adverse effects, the researchers said.
Timing and the Immune System
Circadian rhythms are also seen in immune processes. In a 2023 study in The Journal of Clinical Investigation of vaccine data from 1.5 million people in Israel, researchers found that children and older adults who got their second dose of the Pfizer mRNA COVID vaccine earlier in the day were about 36% less likely to be hospitalized with SARS-CoV-2 infection than those who got an evening shot.
“The sweet spot in our data was somewhere around late morning to late afternoon,” said lead researcher Jeffrey Haspel, MD, PhD, associate professor of medicine in the division of pulmonary and critical care medicine at Washington University School of Medicine in St. Louis.
In a multicenter, 2024 analysis of 13 studies of immunotherapy for advanced cancers in 1663 people, researchers found treatment earlier in the day was associated with longer survival time and longer survival without cancer progression.
“Patients with selected metastatic cancers seemed to largely benefit from early [time of day] infusions, which is consistent with circadian mechanisms in immune-cell functions and trafficking,” the researchers noted. But “retrospective randomized trials are needed to establish recommendations for optimal circadian timing.”
Other research suggests or is investigating possible chronotherapy benefits for depression, glaucoma, respiratory diseases, stroke treatment, epilepsy, and sedatives used in surgery. So why aren’t healthcare providers adding time of day to more prescriptions? “What’s missing is more reliable data,” Dr. Dyar said.
Should You Use Chronotherapy Now?
Experts emphasize that more research is needed before doctors use chronotherapy and before medical organizations include it in treatment recommendations. But for some patients, circadian dosing may be worth a try:
Night owls whose blood pressure isn’t well controlled. Dr. Dyar and Dr. Pigazzani said night-time blood pressure drugs may be helpful for people with a “late chronotype.” Of course, patients shouldn’t change their medication schedule on their own, they said. And doctors may want to consider other concerns, like more overnight bathroom visits with evening diuretics.
In their study, the researchers determined participants’ chronotype with a few questions from the Munich Chronotype Questionnaire about what time they fell asleep and woke up on workdays and days off and whether they considered themselves “morning types” or “evening types.” (The questions can be found in supplementary data for the study.)
If a physician thinks matching the timing of a dose with chronotype would help, they can consider it, Dr. Pigazzani said. “However, I must add that this was an observational study, so I would advise healthcare practitioners to wait for our data to be confirmed in new RCTs of personalized chronotherapy of hypertension.”
Children and older adults getting vaccines. Timing COVID shots and possibly other vaccines from late morning to mid-afternoon could have a small benefit for individuals and a bigger public-health benefit, Dr. Haspel said. But the most important thing is getting vaccinated. “If you can only get one in the evening, it’s still worthwhile. Timing may add oomph at a public-health level for more vulnerable groups.”

A growing stack of research suggests this approach could reduce side effects and improve the effectiveness of a wide range of therapies, including vaccines, cancer treatments, and drugs for depression, glaucoma, pain, seizures, and other conditions. Still, despite decades of research, time of day is rarely considered in writing prescriptions.
“We are really just at the beginning of an exciting new way of looking at patient care,” said Kenneth A. Dyar, PhD, whose lab at Helmholtz Zentrum München’s Institute for Diabetes and Cancer focuses on metabolic physiology. Dr. Dyar is co-lead author of the new blood pressure analysis.
“Chronotherapy is a rapidly growing field,” he said, “and I suspect we are soon going to see more and more studies focused on ‘personalized chronotherapy,’ not only in hypertension but also potentially in other clinical areas.”
The ‘Missing Piece’ in Chronotherapy Research
Blood pressure drugs have long been chronotherapy’s battleground. After all, blood pressure follows a circadian rhythm, peaking in the morning and dropping at night.
That healthy overnight dip can disappear in people with diabetes, kidney disease, and obstructive sleep apnea. Some physicians have suggested a bed-time dose to restore that dip. But studies have had mixed results, so “take at bedtime” has become a less common recommendation in recent years.
But the debate continued. After a large 2019 Spanish study found that bedtime doses had benefits so big that the results drew questions, an even larger, 2022 randomized, controlled trial from the University of Dundee in Dundee, Scotland — called the TIME study — aimed to settle the question.
Researchers assigned over 21,000 people to take morning or night hypertension drugs for several years and found no difference in cardiovascular outcomes.
“We did this study thinking nocturnal blood pressure tablets might be better,” said Thomas MacDonald, MD, professor emeritus of clinical pharmacology and pharmacoepidemiology at the University of Dundee and principal investigator for the TIME study and the recent chronotype analysis. “But there was no difference for heart attacks, strokes, or vascular death.”
So, the researchers then looked at participants’ chronotypes, sorting outcomes based on whether the participants were late-to-bed, late-to-rise “night owls” or early-to-bed, early-to-rise “morning larks.”
Their analysis of these 5358 TIME participants found the following results: Risk for hospitalization for a heart attack was at least 34% lower for “owls” who took their drugs at bedtime. By contrast, owls’ heart attack risk was at least 62% higher with morning doses. For “larks,” the opposite was true. Morning doses were associated with an 11% lower heart attack risk and night doses with an 11% higher risk, according to supplemental data.
The personalized approach could explain why some previous chronotherapy studies have failed to show a benefit. Those studies did not individualize drug timing as this one did. But personalization could be key to circadian medicine’s success.
“Our ‘internal personal time’ appears to be an important variable to consider when dosing antihypertensives,” said co-lead author Filippo Pigazzani, MD, PhD, clinical senior lecturer and honorary consultant cardiologist at the University of Dundee School of Medicine. “Chronotherapy research has been going on for decades. We knew there was something important with time of day. But researchers haven’t considered the internal time of individual people. I think that is the missing piece.”
The analysis has several important limitations, the researchers said. A total of 95% of participants were White. And it was an observational study, not a true randomized comparison. “We started it late in the original TIME study,” Dr. MacDonald said. “You could argue we were reporting on those who survived long enough to get into the analysis.” More research is needed, they concluded.
Looking Beyond Blood Pressure
What about the rest of the body? “Almost all the cells of our body contain ‘circadian clocks’ that are synchronized by daily environmental cues, including light-dark, activity-rest, and feeding-fasting cycles,” said Dr. Dyar.
An estimated 50% of prescription drugs hit targets in the body that have circadian patterns. So, experts suspect that syncing a drug with a person’s body clock might increase effectiveness of many drugs.
A handful of US Food and Drug Administration–approved drugs already have time-of-day recommendations on the label for effectiveness or to limit side effects, including bedtime or evening for the insomnia drug Ambien, the HIV antiviral Atripla, and cholesterol-lowering Zocor. Others are intended to be taken with or after your last meal of the day, such as the long-acting insulin Levemir and the cardiovascular drug Xarelto. A morning recommendation comes with the proton pump inhibitor Nexium and the attention-deficit/hyperactivity disorder drug Ritalin.
Interest is expanding. About one third of the papers published about chronotherapy in the past 25 years have come out in the past 5 years. The May 2024 meeting of the Society for Research on Biological Rhythms featured a day-long session aimed at bringing clinicians up to speed. An organization called the International Association of Circadian Health Clinics is trying to bring circadian medicine findings to clinicians and their patients and to support research.
Moreover, while recent research suggests minding the clock could have benefits for a wide range of treatments, ignoring it could cause problems.
In a Massachusetts Institute of Technology study published in April in Science Advances, researchers looked at engineered livers made from human donor cells and found more than 300 genes that operate on a circadian schedule, many with roles in drug metabolism. They also found that circadian patterns affected the toxicity of acetaminophen and atorvastatin. Identifying the time of day to take these drugs could maximize effectiveness and minimize adverse effects, the researchers said.
Timing and the Immune System
Circadian rhythms are also seen in immune processes. In a 2023 study in The Journal of Clinical Investigation of vaccine data from 1.5 million people in Israel, researchers found that children and older adults who got their second dose of the Pfizer mRNA COVID vaccine earlier in the day were about 36% less likely to be hospitalized with SARS-CoV-2 infection than those who got an evening shot.
“The sweet spot in our data was somewhere around late morning to late afternoon,” said lead researcher Jeffrey Haspel, MD, PhD, associate professor of medicine in the division of pulmonary and critical care medicine at Washington University School of Medicine in St. Louis.
In a multicenter, 2024 analysis of 13 studies of immunotherapy for advanced cancers in 1663 people, researchers found treatment earlier in the day was associated with longer survival time and longer survival without cancer progression.
“Patients with selected metastatic cancers seemed to largely benefit from early [time of day] infusions, which is consistent with circadian mechanisms in immune-cell functions and trafficking,” the researchers noted. But “retrospective randomized trials are needed to establish recommendations for optimal circadian timing.”
Other research suggests or is investigating possible chronotherapy benefits for depression, glaucoma, respiratory diseases, stroke treatment, epilepsy, and sedatives used in surgery. So why aren’t healthcare providers adding time of day to more prescriptions? “What’s missing is more reliable data,” Dr. Dyar said.
Should You Use Chronotherapy Now?
Experts emphasize that more research is needed before doctors use chronotherapy and before medical organizations include it in treatment recommendations. But for some patients, circadian dosing may be worth a try:
Night owls whose blood pressure isn’t well controlled. Dr. Dyar and Dr. Pigazzani said night-time blood pressure drugs may be helpful for people with a “late chronotype.” Of course, patients shouldn’t change their medication schedule on their own, they said. And doctors may want to consider other concerns, like more overnight bathroom visits with evening diuretics.
In their study, the researchers determined participants’ chronotype with a few questions from the Munich Chronotype Questionnaire about what time they fell asleep and woke up on workdays and days off and whether they considered themselves “morning types” or “evening types.” (The questions can be found in supplementary data for the study.)
If a physician thinks matching the timing of a dose with chronotype would help, they can consider it, Dr. Pigazzani said. “However, I must add that this was an observational study, so I would advise healthcare practitioners to wait for our data to be confirmed in new RCTs of personalized chronotherapy of hypertension.”
Children and older adults getting vaccines. Timing COVID shots and possibly other vaccines from late morning to mid-afternoon could have a small benefit for individuals and a bigger public-health benefit, Dr. Haspel said. But the most important thing is getting vaccinated. “If you can only get one in the evening, it’s still worthwhile. Timing may add oomph at a public-health level for more vulnerable groups.”
