ILLUSTRATIVE CASE

A 37-year-old woman with moderate persistent asthma, controlled on the ICS fluticasone (110 μg twice a day) presents to you for an annual exam. She uses her rescue albuterol inhaler a few times per month. Her last exacerbation was 2 years ago. She has never smoked. She is concerned about continuing to take an ICS every day. What alternative regimen would you recommend for this patient?

According to the Centers for Disease Control and Prevention, asthma affected 24.7 million children and adults in the United States in 2018, accounting for 9.8 million physician visits and 1.6 million emergency department (ED) visits.² The National Institutes of Health (NIH) asthma care guidelines, updated in 2020, recommend a SABA prn as step 1 for intermittent asthma, along with nonpharmacologic management.³ Once a patient has persistent asthma, treatment escalation to step 2 calls for use of daily maintenance inhalers as the preferred treatment option.³

However, the 2020 Global Initiative for Asthma (GINA) warns that an as-needed SABA does not protect patients from severe exacerbations, and regular use of a SABA alone (> 3 inhalers/year) can increase the risk of exacerbations.⁴ A meta-analysis and systematic review from 2018 showed that using an ICS/LABA—scheduled and prn for rescue—had lower risk of asthma exacerbations compared with scheduled ICS/LABA with SABA prn for rescue in patients with ­moderate-to-severe persistent asthma.⁵ Interestingly, the updated 2020 NIH guidelines have adopted this strategy. SABA use prn is no longer recommended for rescue in mild and moderate persistent asthma, and the guidelines now suggest that ICS/LABA be used as rescue in addition to daily medication.³

Although evidence has been mounting for adding the as-needed ICS/LABA for rescue in patients on daily medication, the mainstay has been to provide a SABA prn for rescue use.⁵ Confusing matters more, evidence is emerging that as-needed ICS/LABA for rescue alone in certain patients is safe and effective. The randomized controlled Novel START study, an open-label, parallel-group study, compared ICS/LABA prn vs scheduled ICS with SABA prn vs SABA alone prn in adult patients with intermittent or mild persistent asthma.⁶ ICS/LABA prn prevented more exacerbations and provided better daily control than as-needed SABA alone.⁶ In addition, ICS/LABA as needed resulted in fewer severe exacerbations but potentially poorer daily control than ICS with SABA as needed.⁶

The PRACTICAL study investigated treatment of patients with intermittent, mild persistent, and moderate persistent asthma.¹

STUDY SUMMARY

ICS/LABA prn reduced risk of severe exacerbations

The randomized controlled PRACTICAL study was a 52-week, open-label, parallel-group, superiority trial in New Zealand that compared as-needed ICS/LABA (n = 437) to scheduled ICS plus as-needed SABA (n = 448). Patients were 18 to 75 years old, with a diagnosis of asthma. Applying NIH guideline definitions, these patients would fall into intermittent, mild persistent, or moderate persistent asthma categories, and were on either as-needed SABA alone or a scheduled low- to moderate-dose ICS plus an as-needed SABA in the previous 12 weeks.

Patients on an as-needed SABA prerandomization had to have at least 1 of the following: (1) asthma symptoms or need for a SABA at least twice in the past 4 weeks; (2) at least 1 nighttime awakening due to asthma in the past 4 weeks; or (3) a severe exacerbation requiring oral corticosteroids in the past year. Patients on scheduled ICS plus SABA prn prerandomization were required to have either: (1) low or moderate ICS dosing with partly or well-controlled asthma; or (2) if uncontrolled, poor inhaler technique or adherence.

Patients in the ICS/LABA group were given budesonide 200 µg/formoterol 6 µg, 1 puff prn, and patients in the ICS plus as-needed SABA group were given budesonide 200 µg, 1 puff twice daily, and terbutaline 250 µg, 2 puffs prn. All patients received an asthma action plan that provided guidance on when to seek medical care if asthma worsened, as well as a log to note urgent medical visits and use of systemic corticosteroids. A subset of patients had adherence and dosing monitored by electronic inhaler usage monitors. Patients were seen at 0, 4, 16, 28, 40, and 52 weeks.

Outcomes. The primary outcome was the number of severe exacerbations per patient per year, defined as treatment with oral corticosteroids for ≥ 3 days or ED visit or hospital admission requiring systemic corticosteroids. Among the secondary outcomes were number of moderate and severe exacerbations per patient per year (defined as an unplanned medical visit: primary care, ED, hospital admission, and any duration of steroids); time to first severe exacerbation; assessment with the Asthma Control Questionnaire (ACQ-5); adverse outcomes; and quantity of ICS used (analysis done only for the subset with electronic inhaler monitoring).

This study represents a compelling, real-world look at emerging asthma recommendations.

ACQ-5 takes the mean of 5 questions assessing asthma control in the previous week, with each question ranging from 0 (no impairment) to 6 (maximum impairment). The statistician was blinded to the primary outcome.

Results. The rate of severe exacerbations per patient per year was 0.119 in the as-needed ICS/LABA group vs 0.172 in the scheduled ICS plus as-needed SABA group (relative rate [RR] = 0.69; 95% confidence interval [CI], 0.48–1.00). Time to first severe asthma exacerbation was longer in the as-needed ICS/LABA group (hazard ratio = 0.60; 95% CI, 0.40–0.91). The rate of moderate and severe exacerbations per patient per year was lower in the as-needed ICS/LABA group: 0.165 vs 0.237 (RR = 0.70; 95% CI, 0.51–0.95).

ACQ-5 scores were similar at all time points (mean difference = 0.07; 95% CI, –0.03 to 0.17). Adverse events were similar between groups (most commonly nasopharyngitis in both groups). Less ICS was used in the ICS/LABA group (difference = –126.5 µg per day; 95% CI, –171.0 to –81.9).

Study lends support to recent recommendations

This study represents a compelling, real-world look at emerging asthma recommendations. This was the first comprehensive study to show that as-needed ICS/LABA therapy prevents more moderate and severe exacerbations and lengthens the time to first severe exacerbation, compared with scheduled ICS plus SABA prn in intermittent, mild persistent, or moderate persistent asthma. These data have been incorporated into the GINA guidelines, which recommend ICS/LABA prn for step 2.

CAVEATS

Potential bias in study design

The LABA used in this study was formoterol, which has a quicker onset than other LABAs. It is likely that not all LABAs can be used the same way, and both the NIH and GINA guidelines call it out specifically. Additionally, the study’s open-label design can introduce bias but may be the only way to simulate the real-world actions of our patients. Prior studies used placebo inhalers to keep participants and providers blinded but then could not capitalize on the behavior of using only an inhaler prn (as with the ICS/LABA of this study). Finally, there is discordance between the NIH and GINA asthma guidelines on how to use these data.

CHALLENGES TO IMPLEMENTATION

Cost of ICS/LABA may limit its use

Cost is the largest barrier to implementation. Budesonide costs 6 to 10 times more than albuterol per inhaler (retail price of $281-$427 vs $17-$92, respectively).^7,8 However, cost differences are likely negated for patients already on a maintenance inhaler.

Physicians are going to have to play catch-up when it comes to getting older patients their routine, but important, vaccinations missed during the pandemic.

Weekly general vaccination among Medicare beneficiaries aged ≥ 65 year fell by around 80% soon after the national COVID-19 emergency declaration and have recovered only partially and gradually, according to a report by Kai Hong, PhD, and colleagues at the Centers for Disease Control and Prevention, published in the Morbidity and Mortality Weekly Report. “As the pandemic continues,” the investigators stated, “vaccination providers should continue efforts to resolve disruptions in routine adult vaccination.”

The CDC issued guidance recommending postponement of routine adult vaccination in response to the March 13, 2020, COVID-19 national emergency declaration by the U.S. government and also to state and local shelter-in-place orders. Health care facility operations were restricted because of safety concerns around exposure to the SARS-CoV-2 virus. The result was a significant drop in routine medical care including adult vaccinations.

The investigators examined Medicare enrollment and claims data to assess the change in weekly receipt of four routine adult vaccines by Medicare beneficiaries aged ≥65 during the pandemic: (13-valent pneu­mococcal conjugate vaccine [PCV13], 23-valent pneumococ­cal polysaccharide vaccine [PPSV23], tetanus-diphtheria or tetanus-diphtheria-acellular pertussis vaccine [Td/Tdap], and recombinant zoster vaccine [RZV]). The comparison periods were Jan. 6–July 20, 2019, and Jan. 5–July 18, 2020.

Of the Medicare enrollees in the study sample, 85% were White, 7% Black, 2% Asian, 2% Hispanic, and 4% other racial and ethnic groups. For each of the four vaccines overall, weekly rates of vaccination declined sharply after the emergency declaration, compared with corresponding weeks in 2019. In the period prior to the emergency declaration (Jan. 5–March 14, 2020), weekly percentages of Medicare beneficiaries vaccinated with PPSV23, Td/Tdap, and RZV were consistently higher than rates during the same period in 2019.

After the March 13 declaration, while weekly vaccination rates plummeted 25% for PPSV23 and 62% for RZV in the first week, the greatest weekly declines were during April 5-11, 2020, for PCV13, PPSV23, and Td/Tdap, and during April 12-18, 2020, for RZV. The pandemic weekly vaccination rate nadirs revealed declines of 88% for PCV13, 80% for PPSV23, 70% for Td/Tdap, and 89% for RZV.
 

Routine vaccinations increased midyear

Vaccination rates recovered gradually. For the most recently assessed pandemic week (July 12-18, 2020), the rate for PPSV23 was 8% higher than in the corresponding period in 2019. Weekly corresponding rates for other examined vaccines, however, remained much lower than in 2019: 44% lower for RZV, 24% lower for Td/Tdap and 43% lower for PCV13. The CDC Advisory Committee on Immunization Practices voted in June 2019 to stop recommending PCV13 for adults aged ≥65 years and so vaccination with PCV13 among this population declined in 2020, compared with that in 2019.

Another significant drop in the rates of adult vaccinations may have occurred because of the surge in COVID-19 infections in the fall of 2020 and subsequent closures and renewal of lockdown in many localities.
 

Disparities in routine vaccination trends

Dr. Hong and colleagues noted that their findings are consistent with prior reports of declines in pediatric vaccine ordering, administration, and coverage during the pandemic. While the reductions were similar across all racial and ethnic groups, the magnitudes of recovery varied, with vaccination rates lower among racial and ethnic minority adults than among White adults.

The investigators examined Medicare enrollment and claims data to assess the change in weekly receipt of four routine adult vaccines by Medicare beneficiaries aged ≥65 during the pandemic: (13-valent pneu­mococcal conjugate vaccine [PCV13], 23-valent pneumococ­cal polysaccharide vaccine [PPSV23], tetanus-diphtheria or tetanus-diphtheria-acellular pertussis vaccine [Td/Tdap], and recombinant zoster vaccine [RZV]). The comparison periods were Jan. 6–July 20, 2019, and Jan. 5–July 18, 2020.

Of the Medicare enrollees in the study sample, 85% were White, 7% Black, 2% Asian, 2% Hispanic, and 4% other racial and ethnic groups. For each of the four vaccines overall, weekly rates of vaccination declined sharply after the emergency declaration, compared with corresponding weeks in 2019. In the period prior to the emergency declaration (Jan. 5–March 14, 2020), weekly percentages of Medicare beneficiaries vaccinated with PPSV23, Td/Tdap, and RZV were consistently higher than rates during the same period in 2019.

After the March 13 declaration, while weekly vaccination rates plummeted 25% for PPSV23 and 62% for RZV in the first week, the greatest weekly declines were during April 5-11, 2020, for PCV13, PPSV23, and Td/Tdap, and during April 12-18, 2020, for RZV. The pandemic weekly vaccination rate nadirs revealed declines of 88% for PCV13, 80% for PPSV23, 70% for Td/Tdap, and 89% for RZV.
 

Routine vaccinations increased midyear

Vaccination rates recovered gradually. For the most recently assessed pandemic week (July 12-18, 2020), the rate for PPSV23 was 8% higher than in the corresponding period in 2019. Weekly corresponding rates for other examined vaccines, however, remained much lower than in 2019: 44% lower for RZV, 24% lower for Td/Tdap and 43% lower for PCV13. The CDC Advisory Committee on Immunization Practices voted in June 2019 to stop recommending PCV13 for adults aged ≥65 years and so vaccination with PCV13 among this population declined in 2020, compared with that in 2019.

Another significant drop in the rates of adult vaccinations may have occurred because of the surge in COVID-19 infections in the fall of 2020 and subsequent closures and renewal of lockdown in many localities.
 

Disparities in routine vaccination trends

Dr. Hong and colleagues noted that their findings are consistent with prior reports of declines in pediatric vaccine ordering, administration, and coverage during the pandemic. While the reductions were similar across all racial and ethnic groups, the magnitudes of recovery varied, with vaccination rates lower among racial and ethnic minority adults than among White adults.

Children born to mothers in poor cardiovascular health during pregnancy had an almost eight times higher risk for landing in the poorest cardiovascular health category in early adolescence than children born to mothers who had ideal cardiovascular health during pregnancy.

In an observational cohort study that involved 2,302 mother-child dyads, 6.0% of mothers and 2.6% of children were considered to be in the poorest category of cardiovascular health on the basis of specific risk factors.

The children of mothers with any “intermediate” cardiovascular health metrics in pregnancy – for example, being overweight but not obese – were at just more than two times higher risk for poor cardiovascular health in early adolescence.

Although acknowledging the limitations of observational data, Amanda M. Perak, MD, Northwestern University, Chicago, suggested that focusing on whether or not the relationships seen in this study are causal might be throwing the baby out with the bathwater.

“I would suggest that it may not actually matter whether there is causality or correlation here, because if you can identify newborns at birth who have an eight times higher risk for poor cardiovascular health in childhood based on mom’s health during pregnancy, that’s valuable information either way,” said Dr. Perak.

“Even if you don’t know why their risk is elevated, you might be able to target those children for more intensive preventative efforts throughout childhood to help them hold on to their cardiovascular health for longer.”

That said, she thinks it’s possible that the intrauterine environment might actually directly affect offspring health, either through epigenetics modifications to cardiometabolic regulatory genes or possibly through actual organ development. Her group is collecting epigenetic data to study this further.

“We also need to do a study to see if intervening during pregnancy with mothers leads to better cardiovascular health in offspring, and that’s a question we can answer with a clinical trial,” said Dr. Perak.

This study was published on Feb. 16, 2021, in JAMA.
 

Equal footing

“We’ve always talked about cardiovascular health as if everyone is born with ideal cardiovascular health and loses it from there, and I think what this article points out is that not everybody starts on equal footing,” said Stephen R. Daniels, MD, PhD, University of Colorado at Denver, Aurora, who wrote an editorial accompanying the study.

“We need to start upstream, working with mothers before and during pregnancy, but it’s also important to understand, from a pediatric standpoint, that with some of these kids the horse is kind of already out of the barn very early.”

Dr. Daniels is pediatrician in chief and chair of pediatrics at Children’s Hospital Colorado in Aurora.

This study is the first to examine the relevance of maternal gestational cardiovascular health to offspring cardiovascular health and an important first step toward developing new approaches to address the concept of primordial prevention, he said.

“If primary prevention is identifying risk factors and treating them, I think of primordial prevention as preventing the development of those risk factors in the first place,” said Dr. Daniels.

Future trials, he added, should focus on the various mechanistic pathways – biological effects, shared genetics, and lifestyle being the options – to better understand opportunities for intervention.
 

Mother-child pairs

Dr. Perak and colleagues used data from the Hyperglycemia and Adverse Pregnancy Outcomes (HAPO) study and the HAPO Follow-up Study.

Participants were 2,302 mother-child pairs from nine field centers in Barbados, Canada, China, Thailand, United Kingdom, and the United States, and represented a racially and ethnically diverse cohort.

The mean ages were 29.6 years for pregnant mothers and 11.3 years for children. The pregnancies occurred between 2000 and 2006, and the children were examined from 2013 to 2016, when the children were aged 10-14 years.

Using the American Heart Association’s definition of cardiovascular health, the scientists categorized pregnancy health for mothers based on their measures of body mass index, blood pressure, total cholesterol, glucose level, and smoking status at 28 weeks’ gestation. These five metrics of gestational cardiovascular health have been significantly associated with adverse pregnancy outcomes.

They categorized cardiovascular health for offspring at age 10-14 years based on four of these five metrics: body mass index, blood pressure, cholesterol, and glucose.

Only 32.8% of mothers and 42.2% of children had ideal cardiovascular health.

In analyses adjusted for pregnancy and birth outcomes, the associations seen between poor gestational maternal health and offspring cardiovascular health persisted but were attenuated.

Dr. Perak reported receiving grants from the Woman’s Board of Northwestern Memorial Hospital; the Dixon Family; the American Heart Association; and the National Heart, Lung, and Blood Institute. Dr. Daniels reported no conflicts of interest.

The capacity to mount humoral immune responses to COVID-19 vaccinations may be reduced among people who are heavier, older, and male, new findings suggest.

South_agency/Getty Images

The data pertain specifically to the mRNA vaccine, BNT162b2, developed by BioNTech and Pfizer. The study was conducted by Italian researchers and was published Feb. 26 as a preprint.

The study involved 248 health care workers who each received two doses of the vaccine. Of the participants, 99.5% developed a humoral immune response after the second dose. Those responses varied by body mass index (BMI), age, and sex.

“The findings imply that female, lean, and young people have an increased capacity to mount humoral immune responses, compared to male, overweight, and older populations,” Raul Pellini, MD, professor at the IRCCS Regina Elena National Cancer Institute, Rome, and colleagues said.

“To our knowledge, this study is the first to analyze Covid-19 vaccine response in correlation to BMI,” they noted.

“Although further studies are needed, this data may have important implications to the development of vaccination strategies for COVID-19, particularly in obese people,” they wrote. If the data are confirmed by larger studies, “giving obese people an extra dose of the vaccine or a higher dose could be options to be evaluated in this population.”
 

Results contrast with Pfizer trials of vaccine

The BMI finding seemingly contrasts with final data from the phase 3 clinical trial of the vaccine, which were reported in a supplement to an article published Dec. 31, 2020, in the New England Journal of Medicine. In that study, vaccine efficacy did not differ by obesity status.

Akiko Iwasaki, PhD, professor of immunology at the Howard Hughes Medical Institute and an investigator at Yale University, New Haven, Conn., noted that, although the current Italian study showed somewhat lower levels of antibodies in people with obesity, compared with people who did not have obesity, the phase 3 trial found no difference in symptomatic infection rates.

“These results indicate that even with a slightly lower level of antibody induced in obese people, that level was sufficient to protect against symptomatic infection,” Dr. Iwasaki said in an interview.

Indeed, Dr. Pellini and colleagues pointed out that responses to vaccines against influenza, hepatitis B, and rabies are also reduced in those with obesity, compared with lean individuals.

However, they said, it was especially important to study the effectiveness of COVID-19 vaccines in people with obesity, because obesity is a major risk factor for morbidity and mortality in COVID-19.

“The constant state of low-grade inflammation, present in overweight people, can weaken some immune responses, including those launched by T cells, which can directly kill infected cells,” the authors noted.
 

Findings reported in British newspapers

The findings of the Italian study were widely covered in the lay press in the United Kingdom, with headlines such as “Pfizer Vaccine May Be Less Effective in People With Obesity, Says Study” and “Pfizer Vaccine: Overweight People Might Need Bigger Dose, Italian Study Says.” In tabloid newspapers, some headlines were slightly more stigmatizing.

The reports do stress that the Italian research was published as a preprint and has not been peer reviewed, or “is yet to be scrutinized by fellow scientists.”

Most make the point that there were only 26 people with obesity among the 248 persons in the study.

“We always knew that BMI was an enormous predictor of poor immune response to vaccines, so this paper is definitely interesting, although it is based on a rather small preliminary dataset,” Danny Altmann, PhD, a professor of immunology at Imperial College London, told the Guardian.

“It confirms that having a vaccinated population isn’t synonymous with having an immune population, especially in a country with high obesity, and emphasizes the vital need for long-term immune monitoring programs,” he added.
 

Antibody responses differ by BMI, age, and sex

In the Italian study, the participants – 158 women and 90 men – were assigned to receive a priming BNT162b2 vaccine dose with a booster at day 21. Blood and nasopharyngeal swabs were collected at baseline and 7 days after the second vaccine dose.

After the second dose, 99.5% of participants developed a humoral immune response; one person did not respond. None tested positive for SARS-CoV-2.

Titers of SARS-CoV-2–binding antibodies were greater in younger than in older participants. There were statistically significant differences between those aged 37 years and younger (453.5 AU/mL) and those aged 47-56 years (239.8 AU/mL; P = .005), those aged 37 years and younger versus those older than 56 years (453.5 vs 182.4 AU/mL; P < .0001), and those aged 37-47 years versus those older than 56 years (330.9 vs. 182.4 AU/mL; P = .01).

Antibody response was significantly greater for women than for men (338.5 vs. 212.6 AU/mL; P = .001).

Humoral responses were greater in persons of normal-weight BMI (18.5-24.9 kg/m2; 325.8 AU/mL) and those of underweight BMI (<18.5 kg/m2; 455.4 AU/mL), compared with persons with preobesity, defined as BMI of 25-29.9 (222.4 AU/mL), and those with obesity (BMI ≥30; 167.0 AU/mL; P < .0001). This association remained after adjustment for age (P = .003).

“Our data stresses the importance of close vaccination monitoring of obese people, considering the growing list of countries with obesity problems,” the researchers noted.

Hypertension was also associated with lower antibody titers (P = .006), but that lost statistical significance after matching for age (P = .22).

“We strongly believe that our results are extremely encouraging and useful for the scientific community,” Dr. Pellini and colleagues concluded.

The authors disclosed no relevant financial relationships. Dr. Iwasaki is a cofounder of RIGImmune and is a member of its scientific advisory board.

Humoral responses were greater in persons of normal-weight BMI (18.5-24.9 kg/m2; 325.8 AU/mL) and those of underweight BMI (<18.5 kg/m2; 455.4 AU/mL), compared with persons with preobesity, defined as BMI of 25-29.9 (222.4 AU/mL), and those with obesity (BMI ≥30; 167.0 AU/mL; P < .0001). This association remained after adjustment for age (P = .003).

“Our data stresses the importance of close vaccination monitoring of obese people, considering the growing list of countries with obesity problems,” the researchers noted.

Hypertension was also associated with lower antibody titers (P = .006), but that lost statistical significance after matching for age (P = .22).

“We strongly believe that our results are extremely encouraging and useful for the scientific community,” Dr. Pellini and colleagues concluded.

When treating rosacea/telangiectasia with energy-based devices, the 595-nm pulsed dye laser (PDL) or the 532-nm potassium titanyl phosphate (KTP) laser are the first line options, according to a 2020 international consensus publication that Jeremy B. Green, MD, reviewed during a virtual course on laser and aesthetic skin therapy.

During his presentation, he also reviewed laser treatment of scars. “Erythema is an indicator of scar activity,” said Dr. Green, a dermatologist in Coral Gables, Fla. “So, with flat, red scars, vascular devices are the first choice. If you’re going to treat with multiple lasers in a single session, use the vascular laser first, followed by a resurfacing laser if needed. If you treat with a resurfacing laser first, you’ll cause erythema and edema and you’ll obscure that blood vessel target.”

The manuscript, which was created by a panel of 26 dermatologists and plastic and reconstructive surgeons from 13 different countries, also calls for using scar treatment settings that are lower than those used for port wine stains, with mild purpura as the clinical endpoint to strive for.

Vascular lasers are also the expert panel’s first choice when a scar is painful or pruritic, while the second choice is an ablative fractional laser with intralesional triamcinolone and/or 5-fluorouracil (5-FU). “If the scar is hypertrophic, I will combine a vascular laser, then a nonablative or an ablative fractional laser, then intralesional triamcinolone mixed with 5-FU,” said Dr. Green, who was not involved in drafting the recommendations.

As for the first treatment of choice, 80% of the experts chose a pulsed dye laser, while others chose the KTP laser, intense pulsed light (IPL) and the neodymium yttrium aluminum garnet (Nd:YAG) laser. With regard to settings, when using a PDL and a 10-mm spot size, 41% of experts recommend a fluence of 5-6 J/cm², 27% recommend a fluence of 4-5 J/cm², and 27% recommend a fluence of 6-7 J/cm². Pertaining to pulse duration, 50% favor 1.5 milliseconds, 18% use 3 milliseconds, and 18% use .45 milliseconds.

As for timing post surgery, 70% report treating less than 1 week after surgery and 90% report treating within 1 month post surgery. “I prefer to treat about 1 week after sutures are removed so the skin is re-epithelialized,” Dr. Green said. “The bottom line is, with postsurgical, posttraumatic scars, once the skin is healed, the sooner you get at it, the better.”
 

Rosacea

He also discussed the microvascular effects of PDL in combination with oxymetazoline 1% cream, an alpha_1A adrenoceptor agonist, which is approved by the Food and Drug Administration for treatment of persistent facial erythema associated with rosacea. “This has been a hot topic lately,” Dr. Green said. “When the studies were done for FDA approval, there was an observation that vasodilation occurs 5 minutes after application of oxymetazoline, so the venule diameter increases. Sixty minutes after application, vasoconstriction happens, which is the desired clinical effect for patients with facial erythema.”

In a mouse study, researchers led by Bernard Choi, PhD, and Kristin M. Kelly, MD, of the Beckman Laser Institute and Medical Clinic, University of California, Irvine, found that the combination protocol of oxymetazoline application, followed 5 minutes later by PDL, induced persistent vascular shutdown 7 days after irradiation. Vascular shutdown occurred in 67% of vessels treated with oxymetazoline plus PDL at day 7 vs. 17% in those treated with saline plus PDL.

“This is fascinating,” Dr. Green said during the meeting, which was sponsored by Harvard Medical School, Massachusetts General Hospital, and the Wellman Center for Photomedicine. “There is no publication I’m aware of in humans that has explored this timing, but I have used oxymetazoline in my clinic in patients with stubborn erythema and treated them with the vascular laser 5 minutes later.”

In a separate open-label study of 46 patients with moderate to severe facial erythema associated with rosacea, researchers found that oxymetazoline 1% as adjunctive therapy with energy-based therapy was safe and well tolerated, and reduced facial erythema in patients with moderate to severe persistent facial erythema associated with rosacea. Energy sources used were the PDL, KTP, or IPL.

In a study presented during the 2020 American Society for Laser Medicine & Surgery meeting, researchers led by Pooja Sodha, MD, of George Washington University, Washington, conducted a pilot trial of PDL plus oxymetazoline 1% cream for erythematotelangiectatic rosacea. Between baseline and 6 months’ follow-up the Clinician’s Erythema Assessment score fell from 4 to 2.

“Of note, I would also throw the kitchen sink at these patients medically, meaning I love topical ivermectin 1% cream,” Dr. Green said. “In some cases I’ll even use oral ivermectin and an oral tetracycline class antibiotic.”

He reported having received research funding and/or consulting fees from numerous device and pharmaceutical companies.

More than 50% of patients with cognitive impairment have obstructive sleep apnea, according to findings that also reveal OSA severity is correlated to the degree of cognitive impairment and sleep quality.

“The study shows obstructive sleep apnea is common in patients with cognitive impairment. The results suggest that people with cognitive impairment should be assessed for sleep apnea if they have difficulty with sleep or if they demonstrate sleep-related symptoms,” said study investigator David Colelli, MSc, research coordinator at Sunnybrook Health Sciences Centre in Toronto.

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology..
 

Linked to cognitive impairment

OSA is a common sleep disorder and is associated with an increased risk of developing cognitive impairment. It is also prevalent in the general population, but even more common among patients with dementia.

However, the investigators noted, the frequency and predictors of OSA have not been well established in Alzheimer’s disease and other related conditions such as vascular dementia.

The investigators had conducted a previous feasibility study investigating a home sleep monitor as an OSA screening tool. The current research examined potential correlations between OSA detected by this monitor and cognitive impairment.

The study included 67 patients with cognitive impairment due to neurodegenerative or vascular disease. The range of disorders included Alzheimer’s disease, mild cognitive impairment caused by Alzheimer’s disease, dementia caused by Parkinson’s or Lewy body disease, and vascular conditions.

Participants had a mean age of 72.8 years and 44.8% were male. The mean body mass index (BMI) was 25.6 kg/m².

These participants completed a home sleep apnea test, which is an alternative to polysomnography for the detection of OSA.

Researchers identified OSA in 52.2% of the study population. This, Mr. Colelli said, “is in the range” of other research investigating sleep and cognitive impairment.

“In the general population, however, this number is a lot lower – in the 10%-20% range depending on the population or country you’re looking at,” Mr. Colelli said.

He emphasized that, without an objective sleep test, some patients may be unaware of their sleep issues. Those with cognitive impairment may “misjudge how they’re sleeping,” especially if they sleep without a partner, so it’s possible that sleep disorder symptoms often go undetected.
 

Bidirectional relationship?

Participants answered questionnaires on sleep, cognition, and mood. They also completed the 30-point Montreal Cognitive Assessment (MoCA) to assess language, visuospatial abilities, memory and recall, and abstract thinking.

Scores on this test range from 0 to 30, with a score of 26 or higher signifying normal, 18-25 indicating mild cognitive impairment, and 17 or lower indicating moderate to severe cognitive impairment. The average score for study participants with OSA was 20.5, compared with 23.6 for those without the sleep disorder.

Results showed OSA was significantly associated with a lower score on the MoCA scale (odds ratio, 0.40; P = .048). “This demonstrated an association of OSA with lower cognitive scores,” Mr. Colelli said.

The analysis also showed that OSA severity was correlated with actigraphy-derived sleep variables, including lower total sleep time, greater sleep onset latency, lower sleep efficiency, and more awakenings.

The study was too small to determine whether a specific diagnosis of cognitive impairment affected the link to OSA, Mr. Colelli said. “But definitely future research should be directed towards looking at this.”

Obesity is a risk factor for OSA, but the mean BMI in the study was not in the obese range of 30 and over. This, Mr. Colelli said, suggests that sleep apnea may present differently in those with cognitive impairment.

“Sleep apnea in this population might not present with the typical risk factors of obesity or snoring or feeling tired.”

While the new study “adds to the understanding that there’s a link between sleep and cognitive impairment, the direction of that link isn’t entirely clear,” Mr. Colelli said.

“It’s slowly becoming appreciated that the relationship might be bidirectionality, where sleep apnea might be contributing to the cognitive impairment and cognitive impairment could be contributing to the sleep issues.”

The study highlights how essential sleep is to mental health, Mr. Colelli said. “I feel, and I’m sure you do too, that if you don’t get good sleep, you feel tired during the day and you may not have the best concentration or memory.”

Identifying sleep issues in patients with cognitive impairment is important, as treatment and management of these issues could affect outcomes including cognition and quality of life, he added.

“Future research should be directed to see if treatment of sleep disorders with continuous positive airway pressure (CPAP), which is the gold standard, and various other treatments, can improve outcomes.” Future research should also examine OSA prevalence in larger cohorts.
 

Common, undertreated

Commenting on the resaerch, Lei Gao, MD, assistant professor of anesthesia at Harvard Medical School, Boston, whose areas of expertise include disorders of cognition, sleep, and circadian rhythm, believes the findings are important. “It highlights how common and potentially undertreated OSA is in this age group, and in particular, its link to cognitive impairment.”

OSA is often associated with significant comorbidities, as well as sleep disruption, Dr. Gao noted. One of the study’s strengths was including objective assessment of sleep using actigraphy. “It will be interesting to see to what extent the OSA link to cognitive impairment is via poor sleep or disrupted circadian rest/activity cycles.”

It would also be interesting “to tease out whether OSA is more linked to dementia of vascular etiologies due to common risk factors, or whether it is pervasive to all forms of dementia,” he added.

A 16-minute podcast from JAMA: The Journal of the American Medical Association that attempts to discuss structural racism in the U.S. health care system has stirred conversation on social media about the handling and promotion of the episode.

Published on Feb. 23, the episode is hosted on JAMA’s learning platform for doctors and is available for continuing medical education credits.

“No physician is racist, so how can there be structural racism in health care? An explanation of the idea by doctors for doctors in this user-friendly podcast,” JAMA wrote in a Twitter post to promote the episode. That tweet has since been deleted.

“Systemic and interpersonal racism both still exist in our country — they must be rooted out. I do not share the JAMA host’s belief of doing away with the word ‘racism’ will help us be more successful in ending inequities that exists across racial and ethnic lines,” Dr. Katz said. “Further, I believe that we will only produce an equitable society when social and political structures do not continue to produce and perpetuate disparate results based on social race and ethnicity.”

Dr. Katz reiterated that both interpersonal and structural racism continue to exist in the United States, “and it is woefully naive to say that no physician is a racist just because the Civil Rights Act of 1964 forbade it.”

He also recommended JAMA use this controversy “as a learning opportunity for continued dialogue and create another podcast series as an open conversation that invites diverse experts in the field to have an open discussion about structural racism in healthcare.”

The podcast and JAMA’s tweet promoting it were widely criticized on Twitter. In interviews with WebMD, many doctors expressed disbelief that such a respected journal would lend its name to this podcast episode.

B. Bobby Chiong, MD, a radiologist in New York, said although JAMA’s effort to engage with its audience about racism is laudable, it missed the mark.

“I think the backlash comes from how they tried to make a podcast about the subject and somehow made themselves an example of unconscious bias and unfamiliarity with just how embedded in our system is structural racism,” he said. 

Perhaps the podcast’s worst offense was its failure to address the painful history of racial bias in this country that still permeates the medical community, says Tamara Saint-Surin, MD, assistant professor at the University of North Carolina at Chapel Hill.

“For physicians in leadership to have the belief that structural racism does not exist in medicine, they don’t really appreciate what affects their patients and what their patients were dealing with,” Dr. Saint-Surin said in an interview. “It was a very harmful podcast and goes to show we still have so much work to do.”

Along with a flawed premise, she says, the podcast was not nearly long enough to address such a nuanced issue. And Dr. Livingston focused on interpersonal racism rather than structural racism, she said, failing to address widespread problems such as higher rates of asthma among Black populations living in areas with poor air quality.

The number of Black doctors remains low and the lack of representation adds to an environment already rife with racism, according to many medical professionals.

Shirlene Obuobi, MD, an internal medicine doctor in Chicago, said JAMA failed to live up to its own standards by publishing material that lacked research and expertise.

“I can’t submit a clinical trial to JAMA without them combing through methods with a fine-tooth comb,” Dr. Obuobi said. “They didn’t uphold the standards they normally apply to anyone else.”

Both the editor of JAMA and the head of the American Medical Association issued statements criticizing the episode and the tweet that promoted it.

JAMA Editor-in-Chief Howard Bauchner, MD, said, “The language of the tweet, and some portions of the podcast, do not reflect my commitment as editorial leader of JAMA and JAMA Network to call out and discuss the adverse effects of injustice, inequity, and racism in society and medicine as JAMA has done for many years.” He said JAMA will schedule a future podcast to address the concerns raised about the recent episode.

AMA CEO James L. Madara, MD, said, “The AMA’s House of Delegates passed policy stating that racism is structural, systemic, cultural, and interpersonal, and we are deeply disturbed – and angered – by a recent JAMA podcast that questioned the existence of structural racism and the affiliated tweet that promoted the podcast and stated ‘no physician is racist, so how can there be structural racism in health care?’ ”

He continued: “JAMA has editorial independence from AMA, but this tweet and podcast are inconsistent with the policies and views of AMA, and I’m concerned about and acknowledge the harms they have caused. Structural racism in health care and our society exists, and it is incumbent on all of us to fix it.”

In 2019, the U.S. suicide rate dropped for the first time in 14 years, driven largely by a significant decline in firearm-related deaths, according to a new analysis of National Vital Statistics System data.

Since firearms are the “most common and most lethal” mechanism of suicide, the drop in deaths is “particularly encouraging,” Deborah M. Stone, ScD, MSW, MPH, and associates wrote in the Morbidity and Mortality Weekly Report.

The national suicide rate decreased from 14.2 per 100,000 population in 2018 to 13.9 per 100,000 in 2019, a statistically significant drop of 2.1% that reversed a 20-year trend that saw the rate increase by 33% since 1999, they said.

The rate for firearm use, which is involved in half of all suicides, declined from 7.0 per 100,000 to 6.8, for a significant change of 2.9%, said Dr. Stone and associates at the Centers for Disease Control and Prevention’s National Center for Injury Prevention and Control.

The only other method with a drop in suicide rate from 2018 to 2019 was suffocation – the second most common mechanism of injury – but the relative change of 2.3% was not significant, they noted.

Significant declines also occurred in several subgroups: Whites; those aged 15-24, 55-64, and 65-74 years; and those living in counties classified as large fringe metropolitan or micropolitan (urban cluster of ≥ 10,000 but less than 50,000 population), they said, based on data from the National Vital Statistics System.

“These declines, although encouraging, were not uniform, and several states experienced significant rate increases,” the investigators wrote.

The states with significant increases were Hawaii (30.3%) and Nebraska (20.1%), while declines in the suicide rate were significant in five states – Idaho, Indiana, Massachusetts, North Carolina, and Virginia, Dr. Stone and associates reported. Altogether, the rate fell in 31 states, increased in 18, and did not change in 2.

The significance of those changes varied between males and females. Declines were significant for females in Indiana, Massachusetts, and Washington, and for males in Florida, Kentucky, Massachusetts, North Carolina, and West Virginia. Minnesota was the only state with a significant increase among females, with Hawaii and Wyoming posting increases for males, they said.

As the response to the COVID-19 pandemic continues, the investigators pointed out, “prevention is more important than ever. Past research indicates that suicide rates remain stable or decline during infrastructure disruption (e.g., natural disasters), only to rise afterwards as the longer-term sequelae unfold in persons, families, and communities.”

Contrary to previous findings, selective serotonin reuptake inhibitors are not associated with an increased risk of intracerebral hemorrhage (ICH), results of a large observational study show. However, at least one expert urged caution in interpreting the finding.

“These findings are important, especially since depression is common after stroke and SSRIs are some of the first drugs considered for people,” Mithilesh Siddu, MD, of the University of Miami/Jackson Memorial Hospital, also in Miami, said in a statement.

However, Dr. Siddu said “more research is needed to confirm our findings and to also examine if SSRIs prescribed after a stroke may be linked to risk of a second stroke.”

The findings were released ahead of the study’s scheduled presentation at the annual meeting of the American Academy of Neurology.
 

Widely prescribed

SSRIs, the most widely prescribed antidepressant in the United States, have previously been linked to an increased risk of ICH, possibly as a result of impaired platelet function.

To investigate further, the researchers analyzed data from the Florida Stroke Registry (FSR). They identified 127,915 patients who suffered ICH from January 2010 to December 2019 and for whom information on antidepressant use was available.

They analyzed the proportion of cases presenting with ICH among antidepressant users and the rate of SSRI prescription among stroke patients discharged on antidepressant therapy.

The researchers found that 11% of those who had been prescribed antidepressants had an ICH, compared with 14% of those who had not.

Antidepressant users were more likely to be female; non-Hispanic White; have hypertension; have diabetes; and use oral anticoagulants, antiplatelets, and statins prior to hospital presentation for ICH.

In multivariable analyses adjusting for age, race, prior history of hypertension, diabetes and prior oral anticoagulant, antiplatelet and statin use, antidepressant users were just as likely to present with spontaneous ICH as nonantidepressant users (odds ratio, 0.92; 95% confidence interval, 0.85-1.01).

A total of 3.4% of all ICH patients and 9% of those in whom specific antidepressant information was available were discharged home on an antidepressant, most commonly an SSRI (74%).

The authors noted a key limitation of the study: Some details regarding the length, dosage, and type of antidepressants were not available.
 

Interpret with caution

In a comment, Shaheen Lakhan, MD, PhD, a neurologist in Newton, Mass., and executive director of the Global Neuroscience Initiative Foundation, urged caution in making any firm conclusions based on this study.

“We have two questions here: One, is SSRI use a risk factor for first-time intracerebral hemorrhage, and two, is SSRI use after an ICH a risk factor for additional hemorrhages,” said Dr. Lakhan, who was not involved with the study.

“This study incompletely addresses the first because it is known that SSRIs have a variety of potencies. For instance, paroxetine is a strong inhibitor of serotonin reuptake, whereas bupropion is weak. Hypothetically, the former has a greater risk of ICH. Because this study did not stratify by type of antidepressant, it is not possible to tease these out,” Dr. Lakhan said.

“The second question is completely unaddressed by this study and is the real concern in clinical practice, because the chance of rebleed is much higher than the risk of first-time ICH in the general population,” he added.

The study had no specific funding. Dr. Siddu and Dr. Lakhan disclosed no relevant financial relationships.

Reactions to the infusion of natalizumab (Tysabri) for the treatment of multiple sclerosis (MS) are very uncommon, are usually mild, and nearly always occur during, not after, the infusion, new studies show.

Collectively, the results suggest the need to rethink the drug’s mandatory 1-hour postinfusion observation period – particularly when unnecessarily spending time in medical settings is discouraged because of concerns regarding COVID-19, the researchers concluded.

Their findings “highlight a potential opportunity to improve and streamline the infusion and postinfusion monitoring process,” reported the authors of one of the studies. The findings were presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
 

Infusion reactions were rare

“In this systematic review of almost 10,000 natalizumab infusions, all infusion-related adverse events were mild, and no clinically relevant safety concerns were associated with natalizumab infusions,” they said.

The 1-hour postinfusion observation period for natalizumab, approved for the treatment of relapsing remitting MS (RRMS), is mandated by the Food and Drug Administration, as well as the European Medicines Agency, and applies to each dose, regardless of treatment duration, owing to concerns of infusion reactions. However, previous evidence has indicated that reactions are rare and are usually mild.

In addition to adding burden to the treatment regimen for patients and providers alike, any extended time in an environment where there is concern of heightened risk for SARS-CoV-2 exposure is a concern.

To evaluate the frequency, severity, and timing of infusion reactions, Yujie Wang, MD, of the department of neurology at the University of Washington, Seattle, and colleagues reviewed medical records of all patients who received natalizumab at the University of Washington MS Center’s infusion suite between July 2012 and September 2020.

Among 333 patients with RRMS, 9,682 infusions of natalizumab were provided over the study period, with a mean of 27 infusions per patient (range, 1-174). The mean age of the patients was 41 years, and 87 (26%) were male.

Overall, 33 infusion-related adverse events were reported in 26 patients, representing 0.34% of total infusions and 7.8% of patients.

In 77% of cases, the adverse event occurred during the infusion. In 92% of cases, the adverse event occurred within the first 6 months of treatment.

All of the events were described as mild. The most common were itching, gastrointestinal problems, headache, and flushing.

None of the reactions required emergency care or hospitalization. Symptoms were either self-managed or were managed easily with standard care. The treatment was continued in all cases.

“For physicians and providers who care for patients with MS and are comfortable with infusible therapies, it is no surprise that rates of clinically significant infusion reactions were low,” Dr. Wang said. “It is indeed consistent with prior studies that reactions generally occur during rather than post infusion.”

The authors underscored the array of potential benefits in making changes to the requirement. “Anticipated benefits may include reducing SARS-CoV2 exposure risks for patients and staff, reducing patients’ treatment burden, increasing efficiency, as well as improving access to care without neglecting patient safety.”
 

Additional studies show consistent findings

Several other recent studies have shown similar results. In a study published in Multiple Sclerosis in October 2020, researchers with the Amsterdam University Medical Center found that, among 14,174 natalizumab infusions provided to 225 patients with RRMS between 2006 and 2018, 276 infusion-related adverse events occurred (1.95%) among 60 patients.

There were 11 severe infusion-related adverse events in nine patients (4.0%). All documented severe reactions occurred during the infusion. Among 19 moderate adverse events, 17 occurred during the infusion.

The researchers noted that the majority of patients who experienced severe infusion reactions had detectable antibodies against natalizumab. Such antibodies are associated with a higher risk for infusion-related adverse events.

Patients who did not have any symptoms of a reaction during the infusion had no clinically relevant moderate or severe reactions.

“Thus, the need for postinfusion observation will depend on the patients’ clinical status during the infusion,” they wrote. “Consequently, our data suggest that patients who do not have an infusion-related adverse event while receiving natalizumab treatment do not need to stay in the hospital for an additional observation hour.”
 

Rapid infusion protocol

In another recent study published in Multiple Sclerosis and Related Disorders in January 2021, researchers in Australia reported on the use of a rapid infusion protocol of natalizumab and ocrelizumab. The protocol was implemented to reduce the amount of time patients are required to spend in clinical settings during the COVID-19 pandemic.

In their analysis of 269 rapid infusions of natalizumab and 100 rapid infusions of ocrelizumab, there were two infusion-related reactions in the natalizumab group and eight in the ocrelizumab group.

All the reactions were mild to moderate, and no discontinuations were required. None of the reactions occurred during the postinfusion observation period.

“In the setting of COVID-19 pandemic, rapid infusion protocols could potentially save hospital resources and limit patient exposure to a high-risk clinical setting while still maintaining ongoing treatment of multiple sclerosis,” the authors wrote.

Under the rapid infusion protocol, patients receive three standard doses for 1 hour followed by 30 minutes of observation. In addition, infusions are reduced to 30 minutes, explained lead author Louise Rath, of clinical neurosciences, Alfred Health, in Melbourne.

“For our cohort of patients, the side effects were minimal,” she said.

“Rapid infusions allowed patients to have option of hospital in-home or office, ensuring work was not at risk by infusion,” she added. “Our governance has been very supportive, and we will be keeping rapid infusion post COVID.”

The authors have disclosed no relevant financial relationships.

Reactions to the infusion of natalizumab (Tysabri) for the treatment of multiple sclerosis (MS) are very uncommon, are usually mild, and nearly always occur during, not after, the infusion, new studies show.

Collectively, the results suggest the need to rethink the drug’s mandatory 1-hour postinfusion observation period – particularly when unnecessarily spending time in medical settings is discouraged because of concerns regarding COVID-19, the researchers concluded.

Their findings “highlight a potential opportunity to improve and streamline the infusion and postinfusion monitoring process,” reported the authors of one of the studies. The findings were presented at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
 

Infusion reactions were rare

“In this systematic review of almost 10,000 natalizumab infusions, all infusion-related adverse events were mild, and no clinically relevant safety concerns were associated with natalizumab infusions,” they said.

The 1-hour postinfusion observation period for natalizumab, approved for the treatment of relapsing remitting MS (RRMS), is mandated by the Food and Drug Administration, as well as the European Medicines Agency, and applies to each dose, regardless of treatment duration, owing to concerns of infusion reactions. However, previous evidence has indicated that reactions are rare and are usually mild.

In addition to adding burden to the treatment regimen for patients and providers alike, any extended time in an environment where there is concern of heightened risk for SARS-CoV-2 exposure is a concern.

To evaluate the frequency, severity, and timing of infusion reactions, Yujie Wang, MD, of the department of neurology at the University of Washington, Seattle, and colleagues reviewed medical records of all patients who received natalizumab at the University of Washington MS Center’s infusion suite between July 2012 and September 2020.

Among 333 patients with RRMS, 9,682 infusions of natalizumab were provided over the study period, with a mean of 27 infusions per patient (range, 1-174). The mean age of the patients was 41 years, and 87 (26%) were male.

Overall, 33 infusion-related adverse events were reported in 26 patients, representing 0.34% of total infusions and 7.8% of patients.
