Dupilumab to undergo FDA Priority Review for CRSwNP treatment
The Food and Drug Administration will conduct a Priority Review on the supplemental Biologics License Application (sBLA) for dupilumab (Dupixent) as an add-on treatment for adults with inadequately controlled severe chronic rhinosinusitis with nasal polyps (CRSwNP).
CRSwNP is a chronic disease of the upper airway in which patients can experience severe nasal obstruction with breathing difficulties, nasal discharge, reduction or loss of sense of smell and taste, and facial pain or pressure. There are currently no FDA-approved treatments for the disease, Regeneron said in the press release.
The sBLA is based on results from a pair of phase 3 trials in which patients with CRSwNP received either dupilumab plus a standard-of-care corticosteroid nasal spray or the standard-of-care spray alone. In results presented at the 2019 annual meeting of the American Academy of Allergy, Asthma, and Immunology, dupilumab plus the spray improved nasal polyp size, nasal congestion severity, chronic sinus disease, sense of smell, and comorbid asthma outcomes while reducing the need for corticosteroid use and nasal/sinus surgery.
Dupilumab is currently approved in the United States to treat moderate to severe atopic dermatitis in adults whose disease is poorly controlled with topical agents and as a maintenance treatment in combination with other asthma medications in patients aged 12 years and older whose disease is not controlled with their current prescription. The most common adverse events include injection-site reactions, oropharyngeal pain, and cold sores.
The target action date for the FDA decision is June 26, 2019, Regeneron said.

Flu activity down for a second straight week
A second straight week of reduced influenza activity suggests that the 2018-2019 flu season is on the decline, according to the most recent data from the Centers for Disease Control and Prevention.
The proportion of outpatient visits for influenza-like illness (ILI) was 4.7% during the week ending March 2, which means that, thanks to a revision of the number for the previous week (Feb. 23) from 5.0% down to 4.9%, there have been two straight weeks of declines since outpatient visits reached a season-high 5.0% for the week ending Feb. 16, the CDC’s influenza division said March 8. The national baseline level is 2.2%.
This marks the second 2-week drop in ILI visits for the 2018-2019 season, as there was similar dip in the beginning of January before activity started rising again.
This compares with 24 the week before; 32 states were in the high range of 8-10, compared with the 33 reported last week, based on data from the Outpatient ILI Surveillance Network.
There were nine flu-related pediatric deaths reported during the week, with three occurring in the week ending March 2. To underscore the preliminary nature of these data, one of the deaths reported this week occurred in 2016. A total of 64 deaths in children have been associated with influenza so far for the 2018-2019 season, and the total for the 2015-2016 season is now 95, the CDC said.

Heart-harming toxins may hurt hookah smokers
Smoking a water pipe, or hookah, can result in significant inhalation of toxins and an increased risk for short- and long-term cardiovascular health problems, according to a scientific statement issued by the American Heart Association on March 8.
In the statement, published in the journal Circulation, Aruni Bhatnagar, PhD, of the University of Louisville (Ky.) and his colleagues reviewed the potential dangers of water pipe use and offered strategies for prevention.
Data from the 2016 National Youth Tobacco Survey showed that current use (defined as use within the past 30 days) of water pipes by high school students increased in a nonlinear trend from 4.1% in 2011 to 4.8% in 2016, with a peak of 9.4% in 2014. Water pipe tobacco is sold in flavors such as cherry, chocolate, and coffee that appeal to younger consumers, and epidemiology data suggest that youth view water pipes as safer than conventional cigarettes because the water “filters out toxins” according to the statement.
Findings from the National Adult Tobacco Survey showed an increase as well, from 1.5% during 2009-2010 to 3.2% during 2013-2014. Adults cite cultural and social influences, as well as psychological benefits of reduced stress and anger and improved concentration, which may be attributable to nicotine, the researchers noted.
Water pipe smoking involves placing charcoal briquettes on top of a tobacco-filled bowl with a stem immersed in water such that the smoke is pulled through and bubbles up through the water into a mouthpiece. and include tar, phenanthrene, carbon monoxide, heavy metals, and arsenic, as well as nicotine.
The patterns of exposure to toxins during water pipe smoking are unclear, the authors noted.
However, the risks for both short-term and long-term health effects are similar to those associated with cigarettes. “Overall, the short-term cardiovascular effects are consistent with the sympathomimetic effects of nicotine,” according to the statement.
Data on the long-term effects of water pipe smoking on cardiovascular health are limited, but “lifetime exposures exceeding 40 water pipe–years (2 water pipes per day for a total of 20 years or 1 water pipe for 40 years) are associated with a threefold increase in the odds of angiographically diagnosed coronary artery stenosis,” according to the statement. Additional research on long-term health effects may help guide regulation of water pipe products, the authors suggested.
The AHA statement encourages health care providers to take a proactive approach in addressing hookah use by asking patients about it, by advising those who use water pipes to quit, by assisting those who want to quit by providing counseling and social support, and by referring water pipe smokers to legitimate resources for information on the potential for addiction and health risks.
Dr. Bhatnagar received funding from the National Institutes of Health, but he had no other financial conflicts to disclose.

Are You Sitting Down for This?
Not all sedentary behavior is equal, say researchers from Universidad Autónoma de Madrid in Spain, who evaluated the sedentary habits of 5,459 women and 4,740 men.
The researchers note that several studies have found that, unlike, for example, computer use and reading, TV watching is consistently associated with adverse health outcomes, such as metabolic syndrome, obesity, and diabetes mellitus (DM). But different sedentary behaviors (SBs) have different health effects, they add. They cite research that suggests TV and other “passive” SBs (eg, listening or talking while sitting) could be more harmful than “mentally active” SBs, such as computer use and reading. In this study, “passive” sedentary time, such as TV watching, was associated with less recreational activity and higher body weight. Time at the computer and reading were linked to more recreational physical activity but less light-intensity activity at home.
Moreover, each type of SB has a distinct demographic and lifestyle profile, the researchers say. Older age, lower education, unhealthy lifestyle (smoking, worse diet, less physical activity, higher BMI) and chronic morbidity, such as DM or osteomuscular disease, were linked to more TV time. Longer time at the computer or in commuting was linked to younger age, male gender, higher education, and a sedentary job.
Watching TV had no association with total time spent on the rest of leisure-time SBs. The researchers also found that “mentally active” SBs, such as using the computer and reading, tend to cluster.
Many studies have looked at the effects of and connections between SB, lifestyle choices, and health. The researchers of this study say theirs extends knowledge in the field by considering more types of SB (using the computer, commuting, lying in the sun, listening to music, and reading). To their knowledge, they say, no previous study on a representative sample of an entire country has examined the association between TV watching time and the rest of SB, or has reported the full profile of sociodemographic, lifestyle, and health variables associated with each type of SB.
Watching TV was the predominant SB (45% of total sitting time), followed by sitting at the computer (23%), reading (15%), and commuting (12%). The participants spent a mean of 1.96 hours a day watching TV, vs > 1 hour for the other behaviors.

Poor COPD management might increase MI risk in HIV
SEATTLE – Chronic obstructive pulmonary disease is independently associated with an increased risk of myocardial infarction in people with HIV, according to a report at the Conference on Retroviruses and Opportunistic Infections.
Chronic obstructive pulmonary disease (COPD) is known to increase the risk of myocardial infarction (MI) in the general population, but hadn’t been shown until now to do the same in HIV. The study raises the question of whether COPD is being managed adequately in patients with the virus, according to study lead Kristina Crothers, MD, associate professor in the division of pulmonary, critical care & sleep medicine at the University of Washington, Seattle.
The investigators reviewed 25,509 HIV patients in the Center for AIDS Research Network of Integrated Clinical Systems cohort, a large electronic database of HIV-infected people. They defined COPD by diagnostic codes and inhaler prescriptions. MIs were adjudicated by review.
The team identified 423 subjects with moderate to severe COPD, and 698 who had MIs, including 339 type 1 MIs (T1MI) from a ruptured plaque (54%), and 294 (46%) type 2 heart attacks (T2MI) from a supply-demand mismatch due to sepsis or some other problem. In general, T2MIs are far more common in people with HIV.
COPD was associated with a greater than twofold increased risk of MI after adjustment for age, sex, viral load, nadir CD4 count, hypertension, and other confounders. The risk dropped slightly when smoking – both current smoking and pack years – was added to the model (adjusted hazard ratio 1.88, 95% confidence interval, 1.34-2.63).
The association was particularly strong for T2MI, especially in the setting of bacteremia and sepsis, and unlike T1MI, it remained significant after adjustment for smoking.
The study establishes a link between COPD and MI in HIV, but it could not answer what’s going on. Chronic inflammation from the virus could be at play, but the team also found hints of inadequate COPD management.
“About 60% of patients were on inhalers ... but only about 25% of them were on long-acting inhalers. 75% were only on short-acting.” That’s a problem because long-acting inhalers are needed to control exacerbations, Dr. Crothers said.
The study didn’t capture exacerbation rates, but increased rates could help explain the MI risk. Increased rates of pneumonia could as well, since pneumonia is a common cause of sepsis.
“We need to better manage complications of COPD in this population. I think optimizing long-term COPD management could have many beneficial effects,” Dr. Crothers said.
The National Institutes of Health funded the work. Dr. Crothers had no disclosures.

REPORTING FROM CROI 2019
Poor asthma control during pregnancy trims live birth rate
SAN FRANCISCO – and among the live births had a significantly increased rate of both preterm delivery and neonatal intensive care admissions, according to a review of insurance claims data for more than 1 million American women during 2011-2015.
On the other hand, asthma severity, which the researchers inferred based on the type and amount of treatment patients received, showed essentially no link with the live birth rate, Jennifer Yland said at the annual meeting of the American Academy of Allergy, Asthma, and Immunology.
“The findings add to the body of evidence that relate poor asthma control to an increased risk for pregnancy complications.” explained Michael X. Schatz, MD, an allergist at Kaiser Permanente of Southern California, in San Diego, and a coauthor of the study.
Results from several prior studies had shown links between asthma and an increased rate of preterm birth, “but the larger, more generalizable population is a strength of the current findings. Results from prior studies have less frequently shown a link between asthma during pregnancy and neonatal ICU admissions,” he added.“The findings strengthen the case for good asthma control during pregnancy.”
For their review, Ms. Yland and her coauthors used insurance claims data from privately-insured American women aged 12-55 years who were pregnant and had drug prescription records during the study period. The database included 996,861 women without an asthma diagnosis and 29,882 women diagnosed with asthma. The analysis excluded women diagnosed with chronic obstructive pulmonary disease at least twice during pregnancy.
To analyze the pregnancy outcomes by asthma severity Ms. Yland and her associates divided the asthma patients into five subgroups based on the drug regimens they were on during pregnancy as a surrogate marker of disease severity. This analysis showed no relationship between disease severity and live birth rate.
The researchers also ran an analysis that divided patients into the quality of their management during pregnancy – either good or poor – based on either of two markers of poor control: filling five or more prescriptions for a short-acting beta-antagonist, or at least one exacerbation episode defined as an asthma-related emergency department visit, hospitalization, or need for oral corticosteroid treatment. By these criteria 7,135 (24%) of the pregnant women with asthma were poorly controlled. The live birth rate was 74% among women without asthma, 71% among those with well-controlled asthma, and 68% among women with poorly-controlled asthma, reported Ms. Yland, a researcher at the Harvard T.H. Chan School of Public Health in Boston.
In a multivariate analysis that adjusted for demographic differences and comorbidities, women with poorly-controlled asthma had preterm delivery a statistically significant 30% more often than did women with well-controlled asthma, and the rate of neonatal ICU admissions was a significant 24% higher in women with poorly-controlled asthma, compared with women who had well-controlled asthma. However, the rates of small-for-gestational-age infants and infants with congenital malformations was not significantly different between the well-controlled and poorly-controlled subgroups.
The finding that almost a quarter of the pregnant women in the study were poorly controlled wasn’t surprising, Dr. Schatz said in an interview. In some studies as many as half the asthma patients have poor control.
The 24% rate of poor asthma control during pregnancy in the studied women is “most likely an underestimate of poor control in the general population” because the study used data from women with commercial health insurance, noted Sonia Hernandez-Diaz, MD, lead investigator for the study and professor of epidemiology at Harvard T.H. Chan School of Public Health. “More disadvantaged populations, such as pregnant women on Medicaid, tend to have worse control.”
Barriers to good asthma control during pregnancy include smoking, weight gain, undertreatment, poor adherence, and viral infection. The overall approach to managing asthma during pregnancy is the same as when women are not pregnant, although certain asthma medications have a better safety record during pregnancy. “The most reassuring data exist for albuterol and inhaled steroids, particularly budesonide and fluticasone. Reassuring data also exist for the long-acting beta agonists salmeterol and formoterol, which are combined with inhaled steroids, and for montelukast,” Dr. Schatz said.
This is the first study to assess the impact of asthma management on pregnancy outcome in such a large population. The large number of women included provided a lot of statistical power and allowed the analyses to control for several potential confounders, Ms. Yland noted in an interview. She plans to expand the analysis with Medicaid data to try to further increase the generalizability and precision of the findings.

SAN FRANCISCO – and among the live births had a significantly increased rate of both preterm delivery and neonatal intensive care admissions, according to a review of insurance claims data for more than 1 million American women during 2011-2015.
On the other hand, asthma severity, which the researchers inferred based on the type and amount of treatment patients received, showed essentially no link with the live birth rate, Jennifer Yland said at the annual meeting of the American Academy of Allergy, Asthma, and Immunology.
“The findings add to the body of evidence that relate poor asthma control to an increased risk for pregnancy complications.” explained Michael X. Schatz, MD, an allergist at Kaiser Permanente of Southern California, in San Diego, and a coauthor of the study.
Results from several prior studies had shown links between asthma and an increased rate of preterm birth, “but the larger, more generalizable population is a strength of the current findings. Results from prior studies have less frequently shown a link between asthma during pregnancy and neonatal ICU admissions,” he added.“The findings strengthen the case for good asthma control during pregnancy.”
For their review, Ms. Yland and her coauthors used insurance claims data from privately-insured American women aged 12-55 years who were pregnant and had drug prescription records during the study period. The database included 996,861 women without an asthma diagnosis and 29,882 women diagnosed with asthma. The analysis excluded women diagnosed with chronic obstructive pulmonary disease at least twice during pregnancy.

REPORTING FROM AAAAI 2019
Histoplasmosis Manifests After Decades
Immunocompromised patients can be at risk for complications long after the original health issue was resolved—a problem illustrated by a patient who had a heart transplant in 1986 but developed acute progressive disseminated histoplasmosis decades later.
The patient presented with altered mental status; a Mini-Mental State Exam showed confusion. A computed tomography scan of the patient’s head revealed lesions, raising the suspicion of metastatic malignancy, which was ruled out after biopsy of a medial right temporal brain lesion. MRIs of his chest, abdomen, and pelvis revealed bilateral masses on his adrenal glands. Guided adrenal biopsy showed necrotizing granulomas consistent with a diagnosis of disseminated histoplasmosis.
However, that diagnosis was questioned—the patient had lived in Arizona for years, not, for instance, the Midwest, where histoplasmosis is more common. Nor did he have a history of spelunking, prior exposure to bird or bat droppings. He did report a short visit to North Carolina 30 years earlier. And he had been on immunosuppressive drugs for years.
The patient was started on liposomal amphotericin B, which was discontinued when his renal function deteriorated. He was switched to itraconazole, then restarted on amphotericin B with close monitoring after the diagnosis was confirmed. His doses of immunosuppressive drugs were reduced.
The clinicians note that HIV/AIDS and use of immunosuppressive drugs are among the risk factors for disseminated infection. They cite 1 study that found immunosuppression was the single most common risk factor. In another study, the risk of histoplasmosis increased as CD4+ T cells dropped below 300/µL.
The patient’s case was complicated by the fact that it was > 30 years after his heart transplant, and he had made only a short visit to an endemic area. He also had no history of histoplasmosis—the clinicians say a database search turned up the fact that most reported cases were preceded by symptomatic infection.
When charting patient history, they advise placing emphasis on a history of travel to endemic areas and considering histoplasmosis in immunocompromised patients in nonendemic areas.

CDC Expands Assessment Study of Toxic Chemicals Near Military Bases
Per- and polyfluoroalkyl substances (PFAS) are manmade chemicals used in industry and consumer products, such as nonstick cookware, water-repellent clothing, and stain-resistant fabrics. Studies have shown that exposure to PFAS can—among other things—affect growth, learning, and behavior of infants and children; reduce a woman’s chance of getting pregnant; affect the immune system; and increase the risk of cancer.
The 2018 National Defense Authorization Act allowed the CDC and the Agency for Toxic Substances and Disease Registry (ATSDR) to look at PFAS exposure in communities near current or former military bases that are known to have had PFAS in the drinking water. In a pilot study, researchers conducted assessments in Bucks and Montgomery counties in Pennsylvania (near Horsham Air Guard Station and former Naval Air Warfare Center), and in Westhampton, New York (near Gabreski Air National Guard Base).
Now, CDC/ATSDR have expanded the assessments to 8 other communities:
- Berkeley County (WV) near Shepherd Field Air National Guard Base
- El Paso County (CO) near Peterson Air Force Base
- Fairbanks North Star Borough (AK) near Eielson Air Force Base
- Hampden County (MA) near Barnes Air National Guard Base
- Lubbock County (TX) near Reese Technology Center
- Orange County (NY) near Stewart Air National Guard Base
- New Castle County (DE) near New Castle Air National Guard Base
- Spokane County (WA) near Fairchild Air Force Base
The researchers will randomly select people in each community to participate by having their PFAS levels checked in blood and urine samples. The sampling results will provide researchers and public health professionals with information about community-level exposure but also be used to help communities understand the level of risk and how to reduce PFAS exposure.
The assessments, expected to begin this year and continue through 2020, will also “lay the groundwork,” the CDC says, for a multisite health study that will examine the relationship between PFAS exposure and health outcomes.

Second extubation attempts should be judged on their own merits
SAN DIEGO – When attempting a second extubation, improvements in weaning parameters, compared with the first extubation attempt, do not predict success. Instead, the best predictors were the values of the parameters immediately before the second attempt.
“We hypothesized that the change in parameter values was more important than the actual values right before we tried to re-extubate, and that didn’t turn out to be the case. Because it was a smaller study, we can’t say [change in values] is not useful at all, but we didn’t find a strong association. We showed that the magnitude of the effect with the number measured right before the re-extubation is probably your best bet, but you should obviously evaluate the whole clinical scenario,” commented senior author Michael David Maile, MD, assistant professor of anesthesiology at the University of Michigan, Ann Arbor.
The study was presented at the Critical Care Congress sponsored by the Society of Critical Care Medicine by Suraj Trivedi, MD, who is currently an anesthesiology fellow at Stanford (Calif.) Medicine.
Factors such as rapid shallow breathing index (RSBI), negative inspiratory force (NIF), vital capacity (VC), and partial pressure of arterial carbon dioxide (PaCO2) have been shown to predict success or failure of an initial extubation attempt.
There is currently little available guidance on how to proceed when a first extubation attempt fails. The researchers had anticipated that RSBI, NIF, VC, and PaCO2 levels matching the first attempt would be associated with success the second time around.
But their retrospective study of adult patients at the University of Michigan critical care units found that only the change in RSBI values predicted success on a univariate analysis, and that association became statistically insignificant once they corrected for baseline RSBI previous to the re-extubation attempt.
“I think the biggest take-home message is that we have to figure out each attempt to extubate on its own merits. If you’re trying to extubate a patient in the ICU who has potentially been intubated and extubated multiple times, the clinical gut feeling is always that [the patient has] to be better off than the previous attempt. What we are pointing out is that it really doesn’t matter. If the parameters are all within the overall guidelines, it’s still okay to extubate, even if the absolute change in the variables is not better [than the previous attempt],” Dr. Trivedi said in an interview.
“People put a lot of emphasis on the improvement from the first to the second attempt, and this should temper that enthusiasm to put a lot of weight on the change. But I don’t think our data support that the change means nothing,” added Dr. Maile.
The study included 525 patients (42% female). Comorbidities were common: 72% had cardiac arrhythmias, 58% had hypertension, 33% had renal failure, 39% had a pulmonary disorder, and 25% had liver disease.
Univariate analyses showed associations between values of parameters immediately before the second extubation attempt and success in the second extubation attempt, including RSBI (re-extubation success, mean 53.1 vs failure, mean 68.8; P =.0002) and NIF (success, mean –41.2 vs. failure, mean –38.4; P =.036), and VC (success, mean 1009.8 vs. failure, mean 906.8; P =.017).
When the researchers examined changes in parameters between the first and second attempt, only a change in RSBI predicted success (success, value change of 7.1 vs. failure, value change of 0.05; P less than .031). But when they corrected for the RSBI value immediately before the second attempt, the difference was not statistically significant (P = .892).
The study was not funded. Dr. Maile and Dr. Trivedi have no relevant financial disclosures.

If you’re trying to extubate a patient in the ICU who has potentially been intubated and extubated multiple times, the clinical gut feeling is always that [the patient has] to be better off than the previous attempt. What we are pointing out is that it really doesn’t matter. If the parameters are all within the overall guidelines, it’s still okay to extubate, even if the absolute change in the variables is not better [than the previous attempt],” Dr. Trivedi said in an interview.
“People put a lot of emphasis on the improvement from the first to the second attempt, and this should temper that enthusiasm to put a lot of weight on the change. But I don’t think our data support that the change means nothing,” added Dr. Maile.
The study included 525 patients (42% female). Comorbidities were common: 72% had cardiac arrhythmias, 58% had hypertension, 33% had renal failure, 39% had a pulmonary disorder, and 25% had liver disease.
Univariate analyses showed associations between values of parameters immediately before the second extubation attempt and success in the second extubation attempt, including RSBI (re-extubation success, mean 53.1 vs failure, mean 68.8; P =.0002) and NIF (success, mean –41.2 vs. failure, mean –38.4; P =.036), and VC (success, mean 1009.8 vs. failure, mean 906.8; P =.017).
When the researchers examined changes in parameters between the first and second attempt, only a change in RSBI predicted success (success, value change of 7.1 vs. failure, value change of 0.05; P less than .031). But when they corrected for the RSBI value immediately before the second attempt, the difference was not statistically significant (P = .892).
The study was not funded. Dr. Maile and Dr. Trivedi have no relevant financial disclosures.

REPORTING FROM CCC48
Key clinical point: Patient readiness for a second extubation should be judged by current parameters alone.
Major finding: The change in parameter values between first and second extubation attempts was not predictive of success.
Study details: A retrospective analysis of 525 patients.
Disclosures: The study was not funded. Dr. Maile and Dr. Trivedi have no relevant financial disclosures.

Flu season shows signs of peaking
The 2018-2019 flu season may have peaked as the major nationwide measure of influenza activity held steady for the week ending Feb. 23, according to the Centers for Disease Control and Prevention. The proportion of outpatient visits for influenza-like illness (ILI) was 5.0% for the most recent reporting week, the CDC’s influenza division said in its March 1 report. The previous week’s outpatient visit rate, originally reported as 5.1%, was revised this week to 5.0% as well, suggesting that flu activity is no longer increasing.
Activity at the state level was more mixed. The number of states at level 10 on the CDC’s 1-10 scale of ILI activity stayed at 24 as Indiana and North Dakota replaced Tennessee and Wyoming, but the number of states in the high range (8-10) of the activity scale increased from 30 to 33, CDC data show.
The signs of plateauing ILI activity did not, however, extend to flu-related deaths, with 15 reported among children – the highest weekly number for the 2018-2019 season, although 11 actually occurred in previous weeks – during the week ending Feb. 23 and 289 deaths among all ages for the week ending Feb. 16, which is already more than the 268 listed the week before despite less complete reporting (82% vs. 97%), the CDC reported. Total flu-related deaths in children are now up to 56, compared with 138 at the corresponding point in the 2017-2018 season.
