Benralizumab trials cast doubt on eosinophil depletion’s role in COPD treatment
and eosinophilic inflammation, according to results from two phase 3 trials. The data were published in the New England Journal of Medicine.
Benralizumab, an interleukin-5 receptor alpha–directed cytolytic monoclonal antibody, is approved for the treatment of patients with severe eosinophilic asthma. To assess whether the treatment may prevent COPD exacerbations, Gerard J. Criner, MD, chair and professor of thoracic medicine and surgery at Temple University in Philadelphia and colleagues conducted two randomized, double-blind, parallel-group studies: GALATHEA and TERRANOVA. Researchers enrolled patients with frequent moderate or severe COPD exacerbations and blood eosinophil counts of at least 220 per mm3.
A 56-week treatment period
“An eosinophil threshold of 220 per mm3 was selected on the basis of the phase 2 trial of benralizumab in patients with COPD, in which modeling of annual exacerbations according to baseline blood eosinophil count indicated that patients with eosinophil counts above a similar threshold were more likely to have a response to benralizumab,” the authors wrote. “The doses selected were 30 mg, the approved dose for asthma treatment; 100 mg, to inform the safety margin; and 10 mg (in TERRANOVA), to evaluate the dose-efficacy relationship.”
Patients received placebo or benralizumab via subcutaneous injection every 4 weeks for the first three doses, then every 8 weeks for the rest of the 56-week treatment period. The primary end point was the annualized COPD exacerbation rate ratio (benralizumab vs. placebo) at week 56.
The primary analysis populations included 1,120 patients in GALATHEA and 1,545 patients in TERRANOVA. Most patients were white men, and the average age was 65 years. The percentages of patients with current asthma (5.4% in GALATHEA and 3.3% in TERRANOVA) or past asthma (8.3% in GALATHEA and 6.1% in TERRANOVA) were low.
In GALATHEA, the estimated annualized exacerbation rates were 1.19 per year in the 30-mg benralizumab group, 1.03 per year in the 100-mg benralizumab group, and 1.24 per year in the placebo group. Compared with placebo, the rate ratio was 0.96 for 30 mg of benralizumab and 0.83 for 100 mg of benralizumab.
In TERRANOVA, the estimated annualized exacerbation rates for 10 mg, 30 mg, and 100 mg of benralizumab and for placebo were 0.99 per year, 1.21 per year, 1.09 per year, and 1.17 per year, respectively. The corresponding rate ratios were 0.85, 1.04, and 0.93. “At 56 weeks, none of the annualized COPD exacerbation rate ratios for any dose of benralizumab as compared with placebo reached significance in either trial,” the researchers said. “Types and frequencies of adverse events were similar with benralizumab and placebo.”
Depletion of eosinophils in blood and sputum
By week 4, benralizumab substantially depleted blood eosinophils. In addition, treatment substantially depleted sputum eosinophils by week 24. “However, in contrast to the results in benralizumab-treated patients with severe eosinophilic asthma, this eosinophil depletion did not correspond to a significant difference in the rate of exacerbations. This finding, together with the effect on eosinophils – with minimal effect on the COPD exacerbation rate – that was observed in the mepolizumab trials, suggests that eosinophil depletion is unlikely to ameliorate exacerbation outcomes for the majority of patients with COPD,” Dr. Criner and his coauthors concluded. “Future investigation is required to identify additional clinical factors or biomarkers that may characterize the patients with COPD who are most likely to benefit from anti–interleukin-5 receptor antibody therapy.”
The trials were sponsored by AstraZeneca, which manufactures benralizumab (Fasenra), and by Kyowa Hakko Kirin.

Trump administration finalizing ban on flavored e-cigarettes
The Food and Drug Administration is finalizing a compliance policy that will target flavored e-cigarettes and aim to clear the market of unauthorized, non–tobacco-flavored e-cigarette products, U.S. Department of Health & Human Services Secretary Alex M. Azar II announced Sept. 11.
“The Trump administration is making it clear that we intend to clear the market of flavored e-cigarettes to reverse the deeply concerning epidemic of youth e-cigarette use that is impacting children, families, schools, and communities,” Mr. Azar said in a statement. “We will not stand idly by as these products become an on-ramp to combustible cigarettes or nicotine addiction for a generation of youth.”
The announcement comes as the Centers for Disease Control and Prevention and state health departments track hundreds of lung-related illnesses that are linked to the use of e-cigarettes. At least 450 cases have been reported in 33 states and one jurisdiction. Diagnoses include lipoid pneumonia, alveolar hemorrhage, and cryptogenic organizing pneumonia, according to a Sept. 6 press briefing by Ileana Arias, PhD, CDC acting deputy director for non-infectious diseases. Six deaths associated with the illnesses have been reported thus far.
Details of new regulatory action will be forthcoming and will outline enforcement policy for non–tobacco-flavored e-cigarette products that lack premarket authorization, HHS officials said. According to federal rules, all electronic nicotine delivery system (ENDS) products must file premarket tobacco product applications with the FDA within 2 years. Many ENDS products currently on the market are not being legally marketed and are subject to government action, according to the Trump administration.
“Once finalized, this compliance policy will serve as a powerful tool that the FDA can use to combat the troubling trend of youth e-cigarette use,” Ned Sharpless, MD, acting FDA commissioner, said in the statement. “We must act swiftly against flavored e-cigarette products that are especially attractive to children. Moreover, if we see a migration to tobacco-flavored products by kids, we will take additional steps to address youth use of these products.”
Federal officials noted that preliminary numbers from the National Youth Tobacco Survey show a continued rise in youth e-cigarette use, with more than a quarter of high school students current e-cigarette users in 2019. The overwhelming majority of youth e-cigarette users cited the use of fruit, menthol, or mint flavors, according to the preliminary data, which have not yet been published.
According to 2018 survey data, e-cigarette use increased from 12% to 21% among high school students and from 3% to 5% among middle school students from 2017 to 2018. There were 1.5 million more youth e-cigarette users in 2018 than in 2017, and youth who were using e-cigarettes were using them more often, according to the survey.

New genotype of S. pyrogenes found in rise of scarlet fever in U.K.
A new Streptococcus pyogenes genotype (designated M1UK) emerged in 2014 in England causing an increase in scarlet fever “unprecedented in modern times.” Researchers discovered that this new genotype became dominant during this increased period of scarlet fever. This new genotype was characterized by an increased production of streptococcal pyrogenic exotoxin A (SpeA, also known as scarlet fever or erythrogenic toxin A) compared to previous isolates, according to a report in The Lancet Infectious Diseases.

The researchers analyzed changes in S. pyogenes emm1 genotypes sampled from scarlet fever and invasive disease cases in 2014-2016. The emm1 gene encodes the cell surface M virulence protein and is used for serotyping S. pyogenes isolates. Using regional (northwest London) and national (England and Wales) data, they compared genomes of 135 noninvasive and 552 invasive emm1 isolates from 2009-2016 with 2,800 global emm1 sequences.
During the increase in scarlet fever and invasive disease, emm1 S. pyogenes upper respiratory tract isolates increased significantly in northwest London during the March to May periods over 3 years from 5% of isolates in 2014 to 19% isolates in 2015 to 33% isolates in 2016. Similarly, invasive emm1 isolates collected nationally in the same period increased from 31% of isolates in 2015 to 42% in 2016 (P less than .0001). Sequences of emm1 isolates from 2009-2016 showed emergence of a new emm1 lineage (designated M1UK), which could be genotypically distinguished from pandemic emm1 isolates (M1global) by 27 single-nucleotide polymorphisms. In addition, the median SpeA protein concentration was 9 times greater among M1UK isolates than among M1global isolates. By 2016, M1UK expanded nationally to comprise 84% of all emm1 genomes tested. Dataset analysis also identified single M1UK isolates present in Denmark and the United States.
“The expansion of such a lineage within the community reservoir of S. pyogenes might be sufficient to explain England’s recent increase in invasive infection. Further research to assess the likely effects of M1UK on infection transmissibility, treatment response, disease burden, and severity is required, coupled with consideration of public health interventions to limit transmission where appropriate,” Dr. Lynskey and colleagues concluded.
The authors reported that they had no disclosures.

FDA issues warning to JUUL on illegal marketing of e-cigarettes
, citing violation of the Federal Food, Drug, and Cosmetic Act.
According to the letter, JUUL has marketed its e-cigarettes and e-liquids as modified-risk tobacco products without receiving FDA authorization to do so. JUUL’s labeling, advertising, and other consumer-oriented activities to this effect could reasonably lead consumers to believe that JUUL products represent a lower risk of tobacco-related disease, compared with other tobacco products; that they contain a reduced level of a substance; and that they are free of a particular substance or substances.
As evidence, the letter cited testimony given at a July 2019 hearing held by the Subcommittee on Economic and Consumer Policy of the Committee on Oversight and Reform of the House of Representatives, in which a representative from JUUL, speaking to students at a school presentation, said that JUUL products were “much safer than cigarettes” and that the “FDA would approve it any day,” that JUUL products were “totally safe,” that a student “should mention JUUL to his [nicotine-addicted] friend ... because that’s a safer alternative than smoking cigarettes, and it would be better for the kid to use,” and that the FDA “was about to come out and say it [JUUL] was 99% safer than cigarettes ... and that ... would happen very soon.”
In addition, a “Letter from the CEO” that appeared on the JUUL website and was emailed to a parent in response to her complaint that the company sold JUUL products to her child stated that “[JUUL’s] simple and convenient system incorporates temperature regulation to heat nicotine liquid and deliver smokers the satisfaction that they want without the combustion and the harm associated with it.”
In a related press release, acting FDA Commissioner Ned Sharpless, MD, said that “regardless of where products like e-cigarettes fall on the continuum of tobacco product risk, the law is clear that, before marketing tobacco products for reduced risk, companies must demonstrate with scientific evidence that their specific product does in fact pose less risk or is less harmful. JUUL has ignored the law, and very concerningly, has made some of these statements in school to our nation’s youth.”
The FDA has requested a response from JUUL within 15 working days of the letter’s issue. Failure to comply with the Federal Food, Drug, and Cosmetic Act could result in the FDA’s initiating further actions such as civil money penalties, seizure, and/or injunction.

, citing violation of the Federal Food, Drug, and Cosmetic Act.
According to the letter, JUUL has marketed its e-cigarettes and e-liquids as modified-risk tobacco products without receiving FDA authorization to do so. JUUL’s labeling, advertising, and other consumer-oriented activities to this effect could reasonably lead consumers to believe that JUUL products represent a lower risk of tobacco-related disease, compared with other tobacco products; that they contain a reduced level of a substance; and that they are free of a particular substance or substances.
As evidence, the letter cited testimony given at a July 2019 hearing held by the Subcommittee on Economic and Consumer Policy of the Committee on Oversight and Reform of the House of Representatives, in which a representative from JUUL, speaking to students at a school presentation, said that JUUL products were “much safer than cigarettes” and that the “FDA would approve it any day,” that JUUL products were “totally safe,” that a student “should mention JUUL to his [nicotine-addicted] friend ... because that’s a safer alternative than smoking cigarettes, and it would be better for the kid to use,” and that the FDA “was about to come out and say it [JUUL] was 99% safer than cigarettes ... and that ... would happen very soon.”
In addition, a “Letter from the CEO” that appeared on the JUUL website and was emailed to a parent in response to her complaint that the company sold JUUL products to her child stated that “[JUUL’s] simple and convenient system incorporates temperature regulation to heat nicotine liquid and deliver smokers the satisfaction that they want without the combustion and the harm associated with it.”
In a related press release, acting FDA Commissioner Ned Sharpless, MD, said that “regardless of where products like e-cigarettes fall on the continuum of tobacco product risk, the law is clear that, before marketing tobacco products for reduced risk, companies must demonstrate with scientific evidence that their specific product does in fact pose less risk or is less harmful. JUUL has ignored the law, and very concerningly, has made some of these statements in school to our nation’s youth.”

Sensory feedback may smooth walking with a prosthetic leg
A prosthetic leg that elicits the sensation of knee motion and the feeling of the sole of the foot touching the ground may improve walking performance and reduce phantom limb pain, according to a proof-of-concept study with two patients.
With the bionic leg system, the patients performed better during clinically important tests indoors and outdoors, study author Stanisa Raspopovic, PhD, explained during a press briefing about the research. The findings were published in Nature Medicine.
The results indicate that the use of sensory feedback “could be common practice” in prosthetic devices in the future, he said. Dr. Raspopovic is a researcher at Swiss Federal Institute of Technology Zürich and a founder of SensArs Neuroprosthetics, which is based in Lausanne, Switzerland.
Neural prosthetics allow the nervous system and external devices to interact. These brain-machine interfaces may improve quality of life for patients with brain or spinal cord injuries, degenerative disease, or loss of limbs.
“Conventional leg prostheses do not convey sensory information about motion or interaction with the ground to above-knee amputees, thereby reducing confidence and walking speed in the users,” the study authors wrote. Users may also have high levels of mental and physical fatigue, and the lack of physiologic feedback from the extremity to the brain may contribute to the generation of phantom limb pain.
To evaluate whether neural sensory feedback restoration could address these issues, investigators conducted a study with two patients who had undergone transfemoral amputations as a result of traumatic events. The patients were implanted with four intraneural stimulation electrodes in the remaining tibial nerve. The prosthetic leg device included sensors to represent foot touch and pressure and knee joint angle. The sensors transmitted sensory signals to the nervous system through the stimulation electrodes in the tibial nerve.
When the patients walked outdoors over a path traced in the sand, “participants’ speeds were significantly higher when sensory feedback was provided,” the authors wrote. One participant walked 3.56 m/min faster, and the other walked 5.68 m/min faster.
The participants also rated their confidence in the prosthesis on a scale from 0 to 10. For patient 1, self-rated confidence improved from 4.85 to 7.71 with the device. Patient 2 reported a confidence level that climbed from 2.7 to 5.55.
When tested indoors, both patients reached a 0.5 km/hour higher speed on the treadmill when stimulation was provided and both had a lower mean rate of oxygen uptake during the sensory feedback trials, the study authors reported.
Levels of phantom limb pain also decreased significantly after 10-minute stimulation sessions, but not during control sessions.
Longer studies with more patients are required, and fully implantable devices without transcutaneous cables need to be developed, the authors wrote.
Grants from the European Research Council, European Commission, and Swiss National Science Foundation funded the research. Dr. Raspopovic and two coauthors hold shares of SensArs Neuroprosthetics, a start-up company dealing with the commercialization of neurocontrolled artificial limbs.

Less CPAP time linked to exacerbation in COPD/OSA overlap syndrome
and all‐cause mortality, according to a retrospective cohort study.
“These factors should be taken into account when considering the management and prognosis of these patients,” the researchers said in the Clinical Respiratory Journal.
Prior studies have found that patients with COPD and OSA – that is, with overlap syndrome – “have a substantially greater risk of morbidity and mortality, compared to those with either COPD or OSA alone,” said Philippe E. Jaoude, MD, and Ali A. El Solh, MD, both of the Veterans Affairs Western New York Healthcare System in Buffalo and the University at Buffalo.
To identify factors associated with COPD exacerbation and all‐cause mortality in patients with overlap syndrome, Dr. Jaoude and Dr. El Solh reviewed the electronic health records of patients with simultaneous COPD and OSA. They compared patients with overlap syndrome who had an acute exacerbation of COPD during a 42-month period with a control group of patients with overlap syndrome who did not have exacerbations during that time. Patients with exacerbations and controls were matched 1:1 by age and body mass index.
Eligible patients were aged 42-90 years, had objectively confirmed COPD, and had documented OSA by in-laboratory polysomnography (that is, at least five obstructive apneas and hypopneas per hour). The investigators defined a COPD exacerbation as a sustained worsening of a patient’s respiratory condition that warranted additional treatment.
Of 225 eligible patients, 92 had at least one COPD exacerbation between March 2014 and September 2017. Patients with COPD exacerbation and controls had a mean age of about 68 years. The group of patients with exacerbation had a higher percentage of active smokers (21% vs. 9%) and had poorer lung function (mean forced expiratory volume in 1 second percent predicted: 55.2% vs. 64.5%).
“Although the rate of CPAP adherence between the two groups was not significantly different, the average time of CPAP use was significantly higher in patients with no recorded exacerbation,” the researchers reported – 285.4 min/night versus 238.2 min/night.
In all, 146 patients (79.4%) survived, and 38 patients (20.6%) died during the study period. The crude mortality rate was significantly higher in the group with COPD exacerbations (14% vs. 7%).
“Multivariate logistic regression analysis identified the independent risk factors associated with COPD exacerbations as active smoking, worse airflow limitation, and lower CPAP utilization,” they said. “As for all-cause mortality, a higher burden of comorbidities, worse airflow limitation, and lower time of CPAP use were independently associated with poor outcome.”
The researchers noted that they cannot rule out the possibility that patients who were adherent to CPAP were systematically different from those who were not.
The authors had no conflicts of interest.

Vape lung disease cases exceed 400, 3 dead
Vitamin E acetate is one possible culprit in the mysterious vaping-associated lung disease that has killed three patients, sickened 450, and baffled clinicians and investigators all summer.
Another death may be linked to the disorder, officials said during a joint press briefing held by the Centers for Disease Control and Prevention and the Food and Drug Administration. In all, 450 potential cases have been reported and e-cigarette use confirmed in 215. Cases have occurred in 33 states and one territory. A total of 84% of the patients reported having used tetrahydrocannabinol (THC) products in e-cigarette devices.
A preliminary report on the situation by Jennifer Layden, MD, of the department of public health in Illinois and colleagues – including a preliminary case definition – was simultaneously released in the New England Journal of Medicine (2019 Sep 6. doi: 10.1056/NEJMoa1911614).
No single device or substance was common to all the cases, leading officials to issue a blanket warning against e-cigarettes, especially those containing THC.
“We believe a chemical exposure is likely related, but more information is needed to determine what substances. Some labs have identified vitamin E acetate in some samples,” said Dana Meaney-Delman, MD, MPH, incident manager, CDC 2019 Lung Injury Response. “Continued investigation is needed to identify the risk associated with a specific product or substance.”
Besides vitamin E acetate, federal labs are looking at other cannabinoids, cutting agents, diluting agents, pesticides, opioids, and toxins.
Officials also issued a general warning about the products. Youths, young people, and pregnant women should never use e-cigarettes, they cautioned, and no one should buy them from a noncertified source, a street vendor, or a social contact. Even cartridges originally obtained from a certified source should never have been altered in any way.
Dr. Layden and colleagues reported that bilateral lung infiltrates was characterized in 98% of the 53 patients hospitalized with the recently reported e-cigarette–induced lung injury. Nonspecific constitutional symptoms, including fever, chills, weight loss, and fatigue, were present in all of the patients.
Patients may show some symptoms days or even weeks before acute respiratory failure develops, and many had sought medical help before that. All presented with bilateral lung infiltrates, part of an evolving case definition. Many complained of nonspecific constitutional symptoms, including fever, chills, gastrointestinal symptoms, and weight loss. Of the patients who underwent bronchoscopy, many were diagnosed as having lipoid pneumonia, a rare condition characterized by lipid-laden macrophages.
“We don’t know the significance of the lipid-containing macrophages, and we don’t know if the lipids are endogenous or exogenous,” Dr. Meaney-Delman said.
The incidence of such cases appears to be rising rapidly, Dr. Layden noted. An epidemiologic review of cases in Illinois found that the mean monthly rate of visits related to severe respiratory illness in June-August was twice that observed during the same months last year.

Michigan becomes first state to ban flavored e-cigarettes
The state health agency is expected to issue rules outlining the ban within the next 30 days. The emergency ban will be in effect for 6 months, with the possibility of a 6-month extension while state health regulators craft rules to set in place a permanent ban.
The ban will also prohibit “misleading marketing of vaping products, including the use of terms like ‘clean,’ ‘safe,’ and ‘healthy,’ that perpetuate beliefs that these products are harmless,” according to a statement issued by Gov. Whitmer.
Companies selling vaping products “are using candy flavors to hook children on nicotine and misleading claims to promote the belief that these products are safe,” she said in a statement. “That ends today. Our kids deserve leaders who are going to fight to protect them. These bold steps will finally put an end to these irresponsible and deceptive practices and protect Michiganders’ public health.”
The ban also will cover mint- and menthol-flavors in addition to sweet flavors but will not ban tobacco-flavored e-cigarette products.
The American Academy of Pediatrics, American Heart Association, American Lung Association, American Cancer Society Cancer Action Network and other organizations praised the action taken by the state, calling the steps “necessary and appropriate.”
“The need for action is even more urgent in light of the recent outbreak of severe lung illness associated with e-cigarette use and the failure of the U.S. Food and Drug Administration to take strong regulatory action such as prohibiting the sale of the flavored products nationwide that have attracted shocking numbers of our nation’s youth,” the organizations said in a statement.
The groups noted that “health authorities are investigating reports of severe respiratory illness associated with e-cigarette use in at least 215 people ... in 25 states,” adding that many are youth and young adults.
The U.S. Department of Health & Human Services Secretary Alex Azar said in an Aug. 30 statement that the federal government is “using every tool we have to get to the bottom of this deeply concerning outbreak of illness in Americans who use e-cigarettes. More broadly, we will continue using every regulatory and enforcement power we have to stop the epidemic of youth e-cigarette use.”
HHS noted that no single substance or e-cigarette product has been consistently associated with the reports of illness. The agency called upon clinicians to report any new cases as appropriate to their state and local health departments.
Gov. Whitmer earlier this year signed bills that clarify that it is illegal to sell nontraditional nicotine products to minors, but the governor’s statement notes her criticism that the bills did not go far enough to protect the state’s youth, necessitating this further action.

The state health agency is expected to issue rules outlining the ban within the next 30 days. The emergency ban will be in effect for 6 months, with the possibility of a 6-month extension while state health regulators craft rules to set in place a permanent ban.
The ban will also prohibit “misleading marketing of vaping products, including the use of terms like ‘clean,’ ‘safe,’ and ‘healthy,’ that perpetuate beliefs that these products are harmless,” according to a statement issued by Gov. Whitmer.
Companies selling vaping products “are using candy flavors to hook children on nicotine and misleading claims to promote the belief that these products are safe,” she said in a statement. “That ends today. Our kids deserve leaders who are going to fight to protect them. These bold steps will finally put an end to these irresponsible and deceptive practices and protect Michiganders’ public health.”
The ban also will cover mint- and menthol-flavors in addition to sweet flavors but will not ban tobacco-flavored e-cigarette products.
The American Academy of Pediatrics, American Heart Association, American Lung Association, American Cancer Society Cancer Action Network and other organizations praised the action taken by the state, calling the steps “necessary and appropriate.”
“The need for action is even more urgent in light of the recent outbreak of severe lung illness associated with e-cigarette use and the failure of the U.S. Food and Drug Administration to take strong regulatory action such as prohibiting the sale of the flavored products nationwide that have attracted shocking numbers of our nation’s youth,” the organizations said in a statement.
The groups noted that “health authorities are investigating reports of severe respiratory illness associated with e-cigarette use in at least 215 people ... in 25 states,” adding that many are youth and young adults.
The U.S. Department of Health & Human Services Secretary Alex Azar said in an Aug. 30 statement that the federal government is “using every tool we have to get to the bottom of this deeply concerning outbreak of illness in Americans who use e-cigarettes. More broadly, we will continue using every regulatory and enforcement power we have to stop the epidemic of youth e-cigarette use.”

VA Pathologist Indicted for Patient Deaths Due to Misdiagnoses
Levy was chief pathologist at Veterans Health Care System of the Ozarks in Fayetteville, Arkansas. During his 12-year tenure at the US Department of Veterans Affairs (VA), he read almost 34,000 pathology slides. However, at the same time, he was working under the influence of alcohol and 2-methyl-2-butanol (2M2B)—a substance that intoxicates but cannot be detected in routine tests.
The VA fired Levy last year, and the VA Office of the Inspector General (OIG) began an investigation of his actions and of agency lapses in overseeing him. The 18-month review found that 8.9% of Levy’s diagnoses involved clinical errors—the normal misdiagnosis rate for pathologists is 0.7%. Hundreds of Levy’s misdiagnoses were not serious, but ≥ 15 may have led to deaths and harmful illness in 15 other patients. Some patients were not diagnosed when they should have been. Some were told they were sick when they were not and suffered unnecessary invasive treatment.
Levy knowingly falsified diagnoses for 3 veterans. One patient was diagnosed with diffuse large B-cell lymphoma—a type of cancer he did not have. He received the wrong treatment and died. Levy diagnosed another patient, also wrongly, with small cell carcinoma; that patient died of squamous cell carcinoma that spread. The third patient was given a benign test result for prostate cancer. Untreated, he died after the cancer spread.
One patient was given antibiotics instead of treatment for what was later diagnosed as late-stage neck and throat cancer. In an interview with the Washington Post he said, “I went from ‘Your earache isn’t anything’ to stage 4.”
How was Levy able to wreak such havoc? One reason was that despite concerns and complaints from colleagues, he looked good on paper. He falsified records to indicate that his deputy concurred with his diagnoses in mandated peer reviews. He also appeared “clean” in inspections through using 2M2B.
Levy was fired not for his work performance but for being arrested for driving while intoxicated. He had been a “star hire” with an medical degree from the University of Chicago, who had completed a pathology residency at the University of California at San Francisco and a fellowship at Duke University focusing on disease of the blood. But he also had a 1996 arrest for a driving under the influence (DUI) on his record when he joined the VA in 2005.
In 2015, a fact-finding panel interviewed Levy about reports that he was under the influence while on duty. He denied the allegations. In 2016, Levy arrived at the radiology department to assist with a biopsy with a blood alcohol level of nearly 0.4. He was suspended, his alcohol impairment was reported to the state medical boards, and his medical privileges were revoked. He entered a VA treatment program in 2016, then returned to work. Levy, who also sat on oversight boards and medical committees, seemed drowsy and was speaking “nonsense” at an October 2017 meeting of the hospital’s tumor board, according to meeting minutes provided to The Post.
He was suspended again in 2017 for being under the influence but allowed to continue with nonclinical work until he was again arrested for DUI in 2018, when the police toxicology test detected 2M2B. He was finally dismissed in April 2018. Nonetheless, even after he had arrived impaired at the laboratory twice, the VA had awarded him 2 performance bonuses, based on the supposedly low clinical error rate and 42 urine and blood samples that turned up negative for alcohol and drugs.
In addition to 3 counts of involuntary manslaughter, the indictment charges that Levy devised a scheme to defraud the VA and to obtain money and property from the VA in the form of salary, benefits, and performance awards. He is charged with 12 counts of wire fraud, 12 counts of mail fraud, and 4 counts of making false statements related to 12 occasions between 2017 and 2018, when Levy was reportedly buying 2M2B over the Internet while he was contractually obligated to submit to random drug and alcohol screens.
After being fired, Levy moved to a small island in the Dutch Caribbean and found a position teaching pathology at a local medical school. At the time of his VA hiring, Levy held a medical license issued by Mississippi. His active medical licenses in California and Florida were revoked only this spring. The VA did not notify the3 states where Levy was licensed that he could no longer practice until June 2018.
The Office of Inspector General (OIG) has identified other VA physicians who continued to practice even after they were found to have compromised patient care, and the Government Accountability Office found “weak systems” for ensuring that problems are addressed in a timely fashion. A VA spokesperson, however, quoted in The Washington Post, said the Levy case was “an isolated incident,” and that the agency has “strengthened internal controls” to ensure that errors are more quickly identified and addressed. The Fayetteville Medical Center also has increased monitoring of its clinical laboratory, according to a Washington Post report. VA officials also said they have added oversight of small specialty staffs across the system to ensure “independent and objective oversight.”
The VA has contacted the families in the 30 most serious cases to advise them of their legal and treatment options, according to the Washington Post.
“The arrest of Dr. Levy was accomplished as a result of the strong leadership of the US Attorney’s Office and the extensive work of special agents of the VA OIG, supported by the medical expertise of the OIG’s health care inspection professionals,” said Michael Missal, the VA’s inspector general, in a press release issued by the US Attorney’s Office in the Western District of Arkansas. “These charges send a clear signal that anyone entrusted with the care of veterans will be held accountable for placing them at risk by working while impaired or through other misconduct.”
Levy is in jail in Fayetteville. The trial date for his case is set for October 7.

Vaping-related lung disease cases rise, case reporting standardized
The number of possible cases of vaping-related pulmonary illness has risen to 215, reported from 25 states, as of Aug. 27, 2019, according to the Centers for Disease Control and Prevention, Atlanta. Additional reports of pulmonary illness are under investigation.
The CDC has released a standardized case definition that states are using to complete their own investigations and verifications of cases. It appears that all cases are linked to e-cigarette product use, but the cause of the respiratory illnesses is still unconfirmed.
In many cases, patients reported a gradual start of symptoms, including breathing difficulty, shortness of breath, and/or chest pain before hospitalization. Some cases reported mild to moderate gastrointestinal illness including vomiting and diarrhea, or other symptoms such as fevers or fatigue. In many cases, patients have also acknowledged recent use of tetrahydrocannabinol (THC)-containing e-cigarette products while speaking to health care personnel or in follow-up interviews by health department staff, according to a statement from the CDC and the Food and Drug Administration.
The agencies are working with state health departments to standardize information collection at the state level to help build a more comprehensive picture of these incidents, including the brand and types of e-cigarette products, whether any of them would fall within the FDA’s regulatory authority, where they were obtained, and whether there is a link to specific devices, ingredients, or contaminants in the devices or substances associated with e-cigarette product use.
CDC staff have been deployed to Illinois and Wisconsin to assist their state health departments. The agencies have released a Clinician Outreach and Communication Activity (COCA) Clinical Action Alert describing this investigation and asking providers to report possible cases to their state health departments. In addition to a standardized case definition, the agencies have issued a medical chart abstraction form and case interview questionnaire, are reviewing and providing feedback on data collection and health messaging tools for states, and are facilitating information sharing between states with possible cases.
More information on the cases and reporting are available from the CDC.
