Incidence of cardiovascular events is doubled in patients with MS
WEST PALM BEACH, FLA. – The incidence rate of many cardiovascular events is more than doubled in patients with multiple sclerosis (MS), compared with matched controls without MS, according to a study presented at ACTRIMS Forum 2020. The risk of a major adverse cardiac event (MACE) – that is, a first myocardial infarction, stroke, or cardiac arrest – is approximately twofold higher. Venous thromboembolism and peripheral vascular disease also occur at notably increased rates, reported Rebecca Persson, MPH, and colleagues at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis. Ms. Persson is an epidemiologist at the Boston Collaborative Drug Surveillance Program in Lexington, Mass.
Vascular comorbidities are more prevalent in patients with MS than in the general population, but few studies have reported on the incidence of cardiovascular disease after MS diagnosis. To describe rates of incident cardiovascular disease after MS diagnosis and compare them with rates in a matched population without MS, the researchers analyzed data from a U.S. Department of Defense database.
The study included a cohort of 6,406 patients with MS diagnosed and treated during Jan. 2004–Aug. 2017 who had at least one prescription for an MS disease-modifying treatment.
A cohort of 66,281 patients without MS were matched to the patients with MS 10:1 based on age, sex, geographic region, and cohort entry date. The researchers excluded patients with a history of cardiovascular disease or select comorbidities such as dyslipidemia, atrial fibrillation, or a disorder related to peripheral vascular disease. They also excluded patients with a history of treated hypertension or treated type 2 diabetes, defined as diagnosis and treatment within 90 days of each other.
Researchers considered a patient to have a cardiovascular disease outcome – including MI, stroke, cardiac arrest, heart failure, angina or unspecified ischemic heart disease, transient ischemic attack or unspecified cerebrovascular disease, venous thromboembolism, peripheral vascular disease, pericardial disease, bradycardia or heart block, or arrhythmia other than atrial fibrillation or atrial flutter – if the disease was recorded five or more times.
The researchers followed patients from cohort entry until study outcome (separate for each outcome), loss of eligibility, death, or end of data collection. Ms. Persson and colleagues calculated incidence rates (IRs) using the Byar method and incidence rate ratios (IRRs) using Poisson regression for each outcome.
The median age at MS diagnosis or at the matched date was 38 years, and 71% were female. The median duration of record after patients entered the cohort was 7.2 years for patients with MS and 5.3 years for patients without MS.
The IRs of all cardiovascular disease types, with the exception of bradycardia or heart block, were higher for patients with MS, compared with non-MS patients, the researchers reported. Many cardiovascular disease outcomes had IRRs greater than 2. “The incidence of MI was higher among MS patients than among non-MS patients,” the researchers said (IR, 12.4 vs. 5.9 per 10,000 person-years; IRR, 2.11).
“Risk of MACE and risk of stroke were higher among MS patients than among non-MS patients,” the researchers said. Relative risks also were higher among women than among men (2.47 vs. 1.55 for MACE, and 2.19 vs. 1.71 for stroke). When the investigators performed a sensitivity analysis to address the possibility that physicians might misdiagnosis MS symptoms as stroke, the rate of stroke was attenuated among patients with MS, but remained elevated relative to the rate among patients without MS (IRR, 1.63).
The IR of venous thromboembolism was more than 2 times higher among patients with MS than among non-MS patients (38.4 vs. 15.1 per 10,000 person-years; IRR, 2.54), as was the risk of peripheral vascular disease (14.9 vs. 6.0 per 10,000 person-years; IRR, 2.49). The relative risk of peripheral vascular disease was higher in women than men, and the risk in patients with MS increased after age 40 years.
The study was funded by a grant from Celgene, a subsidiary of Bristol-Myers Squibb. Four of Ms. Persson’s coauthors are employees of BMS, and one works for a company that has a business relationship with Celgene.

Phase 2 remyelination trial yields ‘intriguing’ interim results
Placebo and CMN-Au8 help patients with relapsing MS, visual impairment
WEST PALM BEACH, FLA. – Among patients with relapsing multiple sclerosis (MS) and visual impairment who received a potential remyelinating treatment or placebo for as long as 36 weeks, median low-contrast letter acuity improved in the population overall, according to an interim, blinded analysis. Exploratory outcome measures of cognition, gait, and upper extremity function also improved.
The results do not mean that the treatment works. “We know that placebo works. I’m not here to tell you that the drug works. I’m just here to tell you that we have intriguing data,” said Robert Glanzman, MD, chief medical officer of Clene Nanomedicine, the developer of the drug.
The patients in the interim analysis represent about 25% of the target study population of 150 patients, Dr. Glanzman said. The phase 2, double-blind, randomized, controlled trial, VISIONARY-MS, is assessing the efficacy and safety of CNM-Au8, a suspension of clean-surfaced gold nanocrystals that may support intracellular biologic processes. Patients are randomly assigned to receive low-dose CNM-Au8, high-dose CNM-Au8, or placebo taken orally once daily.
Neuroprotective or remyelinating agents are an unmet need in MS, Dr. Glanzman said. VISIONARY-MS has enrolled patients at centers in Australia and recently expanded the trial sites in North America. Dr. Glanzman presented the interim data during a joint symposium of the North American Imaging in MS Cooperative and the International Multiple Sclerosis Visual System Consortium at the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis.
VISIONARY-MS is enrolling participants with chronic optic neuropathy, defined as visual impairment with no episodes of acute optic neuritis within the 6 months prior to enrollment, and nonactive disease, defined as no MS relapses within the prior 3 months. Patients may take concomitant immunomodulatory disease-modifying MS therapies during the trial.
The primary endpoint is improvement in low-contrast letter acuity (LCLA) from baseline to week 24. Secondary endpoints are change in amplitude and latency of multifocal visual evoked potential. Other functional measures are exploratory endpoints. Participants remain in the trial through week 48 or until the last participant completes week 24.
Patients also had median improvement on other subscales of the modified Multiple Sclerosis Functional Composite (MSFC) that assess cognition (Symbol Digit Modalities Test), upper extremity function (9-Hole Peg Test), and gait (Timed 25-foot Walk). CNM-Au8 has been well tolerated, and no serious adverse events related to the study drug have been reported. The most frequent adverse events include headache, upper respiratory infection, and sore throat. Full unblinded results are anticipated in 2021.
About 60% of patients in the interim analysis were female, and the mean Expanded Disability Status Scale score was less than 2, Dr. Glanzman said.
“These data add to the growing body of clinical evidence demonstrating that CNM-Au8, a suspension of catalytic, clean-surfaced, faceted gold nanocrystals, has the unique ability to improve remyelination and provide axonal neuroprotection,” Dr. Glanzman said in a news release. “The consistent median improvements observed across the MSFC functional domains in the population of participants in VISIONARY-MS are exciting.”
At previous meetings, research has described data from studies that have provided evidence of efficacy in animal models of MS. An overview of the preclinical studies – “Nanocatalytic activity of clean-surfaced, faceted nanocrystalline gold enhances remyelination in animal models of multiple sclerosis” – was published recently in Scientific Reports (2020 Feb 11;10[1]:1936). Preclinical studies in animal models of diseases other than MS also have shown evidence of neuroprotection, Dr. Glanzman said.
“We are studying the visual system in order to interrogate the nervous system as a whole,” he said. “The visual system is by far the most sensitive to change.” The design of VISIONARY-MS was informed by a trial of clemastine fumarate as a potential remyelinating agent in patients with chronic optic neuropathy, Dr. Glanzman added.
Dr. Glanzman is an employee of Clene Nanomedicine, and receives salary and stock options.

Increased risk of infection seen in patients with MS
womensWEST PALM BEACH, FLA. – Patients with multiple sclerosis (MS) are at increased risk for most types of infection, with the highest risk associated with renal tract infections, according to an analysis of Department of Defense data.
Susan Jick, DSc, director of the Boston Collaborative Drug Surveillance Program and professor of epidemiology and biostatistics at Boston University, and colleagues sought to understand the rates at which infections occur because they are known to be a common cause of comorbidity and death in patients with MS.
At the meeting held by the Americas Committee for Treatment and Research in Multiple Sclerosis, Dr. Jick and associates presented rates of infection in patients with MS after MS diagnosis, compared with a matched population of patients without MS. The MS cohort included patients who had MS diagnosed and treated between January 2004 and August 2017. Patients had medical history available for at least 1 year before MS diagnosis and at least one prescription for an MS disease-modifying treatment.
Patients without MS were matched to patients with MS 10:1 based on age, sex, geographic region, and cohort entry date. For each patient, the researchers identified the first diagnosed infection of each type after cohort entry. They followed patients until loss of eligibility, death, or end of data collection.
In all, the study included 8,695 patients with MS and 86,934 matched patients without MS. The median age at cohort entry was 41 years, and 71% were female. Median duration of follow-up after study entry was about 6 years. Patients with MS were more likely to have an infection in the year before cohort entry, compared with non-MS patients (43.9% vs. 36.3%).
After cohort entry, the incidence rate of any infection was higher among patients with MS, compared with non-MS patients (4,805 vs. 2,731 per 10,000 person-years; IR ratio, 1.76). In addition, the IR of hospitalized infection was higher among MS patients (125 vs. 51.3 per 10,000 person-years; IRR, 2.43). The IR also was increased for several other types of infections, including renal, skin, fungal, pneumonia or influenza, and other infections (such as rickettsial and spirochetal diseases, helminthiases, and nonsyphilitic and nongonococcal venereal diseases). Eye or ear, respiratory or throat, and viral IRRs “were marginally elevated,” the investigators wrote.
In both cohorts, females had a higher risk of infection than males did. The rate of renal tract infection was more than fourfold higher among females, compared with males, in both cohorts. Relative to non-MS patients, however, men with MS had a higher IRR for renal tract infection than women with MS did (2.47 vs. 1.90).
“The risk for any opportunistic infection was slightly increased among MS patients,” the researchers wrote (520 vs. 338 per 10,000 person-years; IRR, 1.54). This was particularly true for candidiasis (252 vs. 166 per 10,000 person-years; IRR, 1.52) and herpes virus infection (221 vs. 150 per 10,000 person-years; IRR, 1.47). “There were few cases of tuberculosis, hepatitis B infection, or hepatitis C infection,” they noted.
The study was funded by a grant from Celgene, a subsidiary of Bristol-Myers Squibb. Four authors are employees of Bristol-Myers Squibb, and one author works for a company that does business with Celgene.

Median duration of follow-up after study entry was about 6 years. Patients with MS were more likely to have an infection in the year before cohort entry, compared with non-MS patients (43.9% vs. 36.3%).
After cohort entry, the incidence rate of any infection was higher among patients with MS, compared with non-MS patients (4,805 vs. 2,731 per 10,000 person-years; IR ratio, 1.76). In addition, the IR of hospitalized infection was higher among MS patients (125 vs. 51.3 per 10,000 person-years; IRR, 2.43). The IR also was increased for several other types of infections, including renal, skin, fungal, pneumonia or influenza, and other infections (such as rickettsial and spirochetal diseases, helminthiases, and nonsyphilitic and nongonococcal venereal diseases). Eye or ear, respiratory or throat, and viral IRRs “were marginally elevated,” the investigators wrote.
In both cohorts, females had a higher risk of infection than males did. The rate of renal tract infection was more than fourfold higher among females, compared with males, in both cohorts. Relative to non-MS patients, however, men with MS had a higher IRR for renal tract infection than women with MS did (2.47 vs. 1.90).
“The risk for any opportunistic infection was slightly increased among MS patients,” the researchers wrote (520 vs. 338 per 10,000 person-years; IRR, 1.54). This was particularly true for candidiasis (252 vs. 166 per 10,000 person-years; IRR, 1.52) and herpes virus infection (221 vs. 150 per 10,000 person-years; IRR, 1.47). “There were few cases of tuberculosis, hepatitis B infection, or hepatitis C infection,” they noted.
The study was funded by a grant from Celgene, a subsidiary of Bristol-Myers Squibb. Four authors are employees of Bristol-Myers Squibb, and one author works for a company that does business with Celgene.

Specific markers detect psoriatic disease inflammation without elevated CRP
according to a cross-sectional study of patients and healthy controls.
“Different clinical subsets of psoriatic disease based on skin, entheseal, and joint involvement are characterized by specific inflammation marker profiles,” Maria V. Sokolova, MD, of Friedrich-Alexander University Erlangen-Nuremberg and University Clinic Erlangen (Germany) and colleagues reported in Arthritis Research & Therapy. “Treatment of psoriatic disease with cytokine inhibitors reduces these elevated levels of systemic inflammation markers.”
Quantifying systemic inflammation in psoriatic disease has been a challenge, Dr. Sokolova and colleagues wrote. Levels of C-reactive protein (CRP), a commonly used measure of systemic inflammation, “are often low or absent.” To examine other potential markers of systemic inflammation in psoriatic disease, the investigators conducted cross-sectional and longitudinal studies that included healthy controls and patients with psoriatic disease. Patients had isolated or combined manifestations of psoriatic disease, including the skin, the entheses, and the joints. The researchers grouped patients by isolated psoriatic skin disease; isolated enthesitis; isolated arthritis; psoriatic skin disease with enthesitis; psoriatic skin disease with arthritis; arthritis and enthesitis; and combined psoriatic skin disease, arthritis, and enthesitis.
Data from more than 100 patients
The researchers first assessed 10 potential markers using enzyme-linked immunosorbent assay: calprotectin, interleukin-22, IL-8, lipocalin 2, beta-defensin 2, IL-17, IL-23, vascular endothelial growth factors, LL37 (cathelicidin), and pentraxin 3. They measured the markers in 10 healthy controls and 10 patients with active polymorphic psoriatic arthritis. Five parameters – beta-defensin 2, lipocalin 2, IL-22, IL-8, and calprotectin – significantly differed between healthy controls and patients with psoriatic disease. Lipocalin 2, beta-defensin 2, and IL-22 are associated with IL-17/IL-23 activation, and calprotectin and IL-8 are associated with innate immune cell activation. The other markers did not significantly differ or were not detectable in enough participants.
To validate the signals, the researchers measured the five parameters as well as CRP in 105 controls and 105 patients with psoriatic disease, including 15 patients in each of the seven disease pattern groups. “As expected, CRP levels were normal in the majority of individuals,” the authors wrote. The proportion of patients with CRP greater than 5 mg/L was 0% in isolated psoriatic skin disease, 0% in isolated enthesitis; 20% in isolated arthritis; 7% in psoriatic skin disease with enthesitis; 33% in psoriatic skin disease with arthritis; 27% in arthritis with enthesitis; and 33% in combined psoriatic skin disease, arthritis, and enthesitis.
“Only a subset of patients with arthritis, but not patients with skin or entheseal disease show elevated CRP,” the researchers wrote. “In sharp contrast,” beta-defensin 2 and lipocalin 2 were elevated in a majority of patients with monomorphic skin and entheseal disease, but not in joint disease. “Both proteins were significantly correlated to the extent of skin disease and to a lesser extent also entheseal disease,” they added. Calprotectin and IL-8 were elevated in a majority of patients with joint disease and correlated with the extent of arthritis. “IL-22 was elevated ... in all three manifestations of psoriatic disease,” and the vast majority of patients with polymorphic disease had “widespread marker elevation,” the researchers wrote.
Effects of treatment
In a study of 20 patients with psoriatic arthritis, treatment with secukinumab or adalimumab significantly lowered all five markers. Compared with tumor necrosis factor inhibition with adalimumab, “IL-17 inhibition [with secukinumab] showed a more pronounced lowering of lipocalin 2 and beta-defensin 2 levels,” the investigators noted.
“These results confirm earlier data showing elevated beta-defensin levels in psoriasis patients and its association with the extent of skin involvement,” Dr. Sokolova and colleagues wrote. “Overall, these results offer a new possibility to measure systemic inflammation in psoriatic disease.”
The study was supported by the German Research Foundation and other grant and fellowship funding. The authors had no competing interests.

Cigarette smoking is associated with prefrontal function in patients with schizophrenia
Patients with schizophrenia have decreased chronnectomic density in the dorsolateral prefrontal cortex, compared with healthy controls, and cigarette smoking in patients with schizophrenia may be associated with a degree of preserved function in that brain region, researchers reported. The results indicate that smoking may be associated with a preservation effect, but it “cannot restore patients’ prefrontal dysfunction to normal levels,” the researchers said.
The chronnectome depicts how brain functional connectivity patterns (i.e., the connectome) vary over time. “Therefore, the chronnectome may be an effective index to evaluate the smoking-related prefrontal functional changes in schizophrenia,” said Yun-Shuang Fan, a researcher at the Clinical Hospital of Chengdu Brain Science Institute in China, and colleagues in the report, which was published in Progress in Neuro-Psychopharmacology & Biological Psychiatry.
The investigators studied 49 patients with schizophrenia, including 22 smokers and 27 nonsmokers, and 43 healthy controls, including 22 smokers and 21 nonsmokers. Participants underwent resting-state functional magnetic resonance imaging, and the researchers analyzed chronnectomic density using a sliding-window method. The investigators examined interactions between smoking status and diagnosis.
Smoking was associated with reduced chronnectomic density in healthy controls, but increased density in patients with schizophrenia. The study provides a “framework to elaborate upon the self-medication hypothesis in schizophrenia” and sheds “some fresh light on the elevated rates of smoking in schizophrenia,” they said.
The study was relatively small, and patients’ use of antipsychotic medications, which can affect the connectome, may limit the results. In addition, the study’s cross-sectional design precludes knowing whether “smoking behavior is the cause or result of the prefrontal chronnectome alterations in schizophrenia,” the authors added.
The study was supported by the National Natural Science Foundation of China and the Sichuan Science and Technology Program. The researchers had no conflicts of interest.

Blood pressure categories may signal maternal, perinatal risks
GRAPEVINE, TEX. – Blood pressure categories created by the American College of Cardiology (ACC) and American Heart Association (AHA) in 2017 identify patients with increased risk of preeclampsia, preterm birth, and perinatal death when applied to the first 20 weeks of pregnancy, according to a retrospective study presented at the meeting sponsored by the Society for Maternal-Fetal Medicine.
The absolute risk increases are small, and it is unknown whether treating these patients differently would be beneficial, said study author Martha Tesfalul, MD, maternal-fetal medicine clinical fellow at University of California, San Francisco. Nevertheless, , Dr. Tesfalul said.
Cutoffs with unclear implications
The ACC/AHA in November 2017 reclassified blood pressure in nonpregnant adults, but “implications of these categories in pregnancy are still unclear,” Dr. Tesfalul and colleagues said. Under the guidelines, normal blood pressure is systolic blood pressure less than 120 mm Hg and diastolic blood pressure less than 80 mm Hg. Elevated blood pressure is defined as systolic blood pressure between 120 and 129 mm Hg and diastolic blood pressure less than 80 mm Hg. Stage 1 hypertension is systolic blood pressure between 130 and 139 mm Hg or diastolic blood pressure between 80 and 89 mm Hg. And stage 2 hypertension is systolic blood pressure of at least 140 mm Hg or diastolic blood pressure of at least 90 mm Hg.
For the present analysis, the researchers retrospectively compared obstetric and perinatal outcomes for approximately 6,000 pregnancies at an academic center for which they had at least one blood pressure measurement prior to 20 weeks. The highest measurement was used to identify women with normal blood pressure, elevated blood pressure, or stage 1 hypertension according to the 2017 thresholds.
The researchers included singleton pregnancies with delivery between January 2014 and October 2017. They excluded patients with a prior diagnosis of chronic hypertension, autoimmune or chronic renal disease, or fetal anomalies. They examined rates of gestational hypertension, preeclampsia, preterm birth, neonatal intensive care admission, and perinatal death.
Adjusted relative risks
Dr. Tesfalul and colleagues identified about 3,500 pregnancies with normal blood pressure, more than 1,300 pregnancies with elevated blood pressure, and nearly 1,100 pregnancies with stage 1 hypertension.
After adjusting for relevant covariates – maternal age, nulliparity, race, body mass index, in vitro fertilization, tobacco use, pregestational diabetes, and aspirin use – elevated blood pressure and stage 1 hypertension were associated with a higher risk of preeclampsia and severe preeclampsia, relative to normal blood pressure. The proportion of patients with preeclampsia was 5.7% in the normal blood pressure group, 11.7% in the elevated blood pressure group (adjusted relative risk, 1.8), and 15% in the stage 1 hypertension group (adjusted RR, 2.1). The proportion with preeclampsia with severe features was 3.1% in the normal blood pressure group, 5.7% in the elevated blood pressure group (adjusted RR, 1.6), and 6.8% in the stage 1 hypertension group (adjusted RR, 1.8).
In addition, stage 1 hypertension, compared with normal blood pressure, was associated with increased odds of preterm birth at less than 37 weeks (7.9% vs. 5.1%; adjusted RR, 1.4) and perinatal death (0.7% vs. 0.4%; adjusted RR, 2.8).
“Patients with elevated blood pressure and stage 1 hypertension prior to 20 weeks are at increased risk of adverse outcomes,” the authors concluded. “Further research [is] needed to determine optimal care of patients with elevated blood pressure and stage 1 hypertension in pregnancy.”

REPORTING FROM THE PREGNANCY MEETING
Patients remain satisfied despite reduced use of opioids post partum
GRAPEVINE, TEX. – The amount of opioids prescribed post partum may decline over time without affecting levels of pain control satisfaction, according to research presented at the meeting sponsored by the Society for Maternal-Fetal Medicine.
Data from a large center indicate that trends in opioid use significantly declined from 2017 to 2019, but not at the expense of adequate pain control, said Nevert Badreldin, MD, assistant professor of obstetrics and gynecology at Northwestern University in Chicago. Patients consistently reported that they were satisfied with inpatient pain control, while opioid use per inpatient day decreased from about 30 morphine milligram equivalents (MME) to less than 20 MME during that time.
To assess trends in postpartum opioid prescribing, opioid use, and pain control satisfaction, Dr. Badreldin and colleagues evaluated data from a prospective observational study. Their analysis included data from women who used an opioid during postpartum hospitalization between May 2017 and July 2019. The researchers excluded women with NSAID or morphine allergies or recent opioid use, as well as those who received general anesthesia without concurrent neuraxial anesthesia, those who underwent peripartum hysterectomy, and women admitted to the ICU.
The investigators used nonparametric tests of trend to assess the difference over time in the proportion of patients who received an opioid prescription at discharge and in the total MME prescribed post partum.
Of 900 women with inpatient opioid use, 471 agreed to be followed after discharge. In that group, the amount of opioid use per inpatient day significantly declined. In addition, the percentage who received an opioid prescription at discharge significantly declined, as did the total MME prescribed at discharge.
“Both inpatient and outpatient satisfaction with pain control were unchanged,” the researchers reported. “In this population, both the frequency and amount of opioid use in the postpartum period declined from 2017 to 2019, without any change in satisfaction with pain control.”
The study was supported by the Society for Maternal-Fetal Medicine/AMAG 2017 Health Policy Award, and a coauthor received support from the National Institute of Child Health and Human Development.

REPORTING FROM THE PREGNANCY MEETING
Report chastises government for allowing flavored e-cigarettes
according to a report on federal and state policies.
In its annual “State of Tobacco Control” report, the American Lung Association called out the federal government for issuing “inadequate guidance on flavored e-cigarettes that leaves thousands of flavored e-cigarettes on the market.” The organization urged Congress and the Food and Drug Administration “to eliminate all flavored tobacco products from the marketplace, including menthol cigarettes, flavored cigars, and e-cigarettes,” in 2020.
“Flavored tobacco products cause kids to become hooked, and now more than one in four teens (27.5%) are vaping, a staggering 135% increase over the past 2 years,” the association wrote in a news release. Federal guidance on Jan. 2, 2020, permits the sale of flavored e-cigarettes that do not use cartridges. This guidance represented a reversal after officials said in a prior announcement that regulators would “clear the market” of flavored e-cigarettes.
Graphic warning labels
The report also asked the FDA to reject product marketing applications that fail to meet public health standards, calls on the U.S. Department of Health & Human Services to “clarify and ensure that all tobacco users have access to a comprehensive tobacco cessation benefit,” and urges Congress to increase federal funding for the Centers for Disease Control and Prevention’s Office on Smoking and Health to help stop youth e-cigarette use.
“Raising the federal minimum age of sale to 21, which took effect immediately on Dec. 30, was an important first step forward,” the report says. “The American Lung Association successfully advocated for the legislation to be comprehensive and to close state exemptions, such as for military personnel, while also not limiting states from pursuing stronger protections. Additional rules from FDA to provide guidance on the law’s implementation are forthcoming.”
The FDA is expected to release graphic warning labels for cigarette packs in March. After legal setbacks to the Tobacco Control Act of 2009, which required the FDA to ensure all cigarette packs had graphic warning labels by 2011, a judgment “compels FDA to release final graphic warnings by March 15, 2020, with the warning labels appearing on all cigarette packs by June of 2021,” the American Lung Association report said.
“While the American Lung Association recognizes the federal government with an A grade for passage of a strong federal Tobacco 21 law [raising the minimum age of purchase], it also earns an F for its failure to comprehensively oversee tobacco products,” said Harold P. Wimmer, national president and CEO of the American Lung Association, in the news release. “Without meaningful actions by the federal government, the health and the future of our nation’s children are being compromised.”
The federal government received an F for its tobacco tax policies, a D for cessation coverage, and an A for its mass media campaigns, “Tips from Former Smokers” and “The Real Cost.”
Grading states
In addition, the report graded each state and the District of Columbia in terms of funding for tobacco prevention programs, strength of smoke-free workplace laws, level of state tobacco taxes, and coverage of and access to services to quit tobacco. None scored all A’s, but California, the District of Columbia, Maine, New York, and Vermont ranked the highest. Alabama, Mississippi, and North Carolina, on the other hand, received all F’s.
In November, Massachusetts became the first state to prohibit the sale of flavored tobacco products, including menthol cigarettes, and more states should follow suit, according to the association.

Rate of suicide is higher in people with neurologic disorders
The absolute risk difference is small, but statistically significant. “These findings do not necessarily warrant changing the management of treatment for individual patients,” wrote Annette Erlangsen, PhD, a researcher at the Danish Research Institute for Suicide Prevention in Hellerup, and colleagues. “As with all patients, physicians should be aware of the potential for depression, demoralization, and suicide.”
In addition, dementia, Alzheimer’s disease, and intellectual disabilities may be associated with lower suicide rates, according to the study, which was published in JAMA.
“Plausible mechanisms” could underlie the association between neurologic disease and suicide, the authors wrote. A neurologic diagnosis “may constitute a distressing life event,” and the diseases may have psychological, physical, and psychiatric effects. Patients may see themselves as a burden or have less financial security. In addition, the diseases may entail “communication difficulties, poor sleep, and pain.” Neurologic diseases may alter brain circuitry and functioning and influence aggression and impulsivity. “People with neurologic disorders may also have easier access to toxic medication,” they added.
More than a dozen conditions examined
Prior studies have found associations between neurologic conditions and rates of suicide, but data have been inconclusive or inconsistent for some of the disorders. To examine whether people with neurologic disorders have higher suicide rates, relative to people without these disorders, the researchers conducted a retrospective study. They analyzed data from more than 7.3 million people aged 15 years or older who lived in Denmark between 1980 and 2016. The cohort included more than 1.2 million people with neurologic disorders. The investigators identified neurologic disorders using ICD codes for head injury, stroke, epilepsy, polyneuropathy, diseases of the myoneural junction, Parkinson’s disease, multiple sclerosis, CNS infections, meningitis, encephalitis, amyotrophic lateral sclerosis, Huntington’s disease, dementia, intellectual disability, and other brain disorders. They compared incidence rates using a Poisson regression model and adjusted for time period, sex, age, region, socioeconomic status, comorbidity, self-harm or psychiatric hospitalization prior to a neurologic diagnosis, and whether a person lived alone.
In all, 35,483 people in the cohort died by suicide at an average age of about 52 years; 77.4% were male. About 15% of those who died by suicide had a neurologic disorder. The suicide incidence rate among people with a neurologic disorder was 44.0 per 100,000 person-years, whereas the rate among people without a neurologic disorder was 20.1 per 100,000 person-years.
The adjusted incidence rate ratio for people with a neurologic disorder was 1.8. The rate ratio was highest during the 3 months after diagnosis, at 3.1. Huntington’s disease and amyotrophic lateral sclerosis were associated with “the largest excess adjusted [incidence rate ratios] of suicide mortality,” with a rate ratio of 4.9 for each condition, the researchers reported. The adjusted incidence rate ratio was 1.7 for head injury, 1.3 for stroke, 1.7 for epilepsy, 1.4 for intracerebral hemorrhage, 1.3 for cerebral infarction, 1.3 for subarachnoid hemorrhage, 1.7 for polyneuropathy and peripheral neuropathy, 2.2 for Guillain-Barré syndrome, 1.9 for diseases of myoneural junction and muscle, 1.8 for other brain disorders, 1.7 for Parkinson’s disease, 2.2 for multiple sclerosis, and 1.6 for CNS infection.
Compared with people without a neurologic condition, people with dementia, Alzheimer’s disease, and intellectual disabilities had lower suicide rates, with adjusted incidence rate ratios of 0.8, 0.2, and 0.6, respectively. “However, the adjusted [incidence rate ratio] for people with dementia during the first month after diagnosis was 3.0,” the researchers wrote.
In addition, the suicide rate increased with an increasing cumulative number of hospital contacts for neurologic conditions.
Overall incidence rates declined
“Over the study period, the suicide incidence rate for people with neurological disorders decreased from 78.6 per 100,000 person-years during the 1980-1999 years to 27.3 per 100,000 person-years during the 2000-2016 years,” wrote Dr. Erlangsen and colleagues. “The suicide incidence rate for those without a disorder decreased from 26.3 to 12.7 during the same time spans. ... The decline in the overall suicide rate over time did not affect the relative risk pattern.”
The decline in the general suicide rate in Denmark “has largely been attributed to means restriction, such as efforts to limit availability of firearms and particularly toxic medication,” the authors added.
In those time spans, the adjusted incidence rate ratio for suicide among those with dementia decreased from 2.4 to 1.0, and among those with multiple sclerosis from 2.0 to 1.0. “It is possible that the improvements observed for dementia and multiple sclerosis may be related to improvements in treatment and intensified community-based support,” Dr. Erlangsen and coauthors wrote.
When the researchers used people with rheumatoid arthritis as a reference group, those with a neurologic disorder had a higher suicide rate per 100,000 person-years, 30.2 versus 18.4. The adjusted incidence rate ratio for that comparison was 1.4.
In patients with Huntington’s disease, depression mediated by hyperactivity in the hypothalamic-pituitary-adrenal axis may contribute to the risk of suicide. “Witnessing the course of the disease in one’s parent” also may contribute the risk, the researchers wrote.
The analysis may have missed people with neurologic disorders diagnosed before 1977 if they did not have subsequent contact with a hospital, the investigators noted. In addition, diagnoses given in primary care were not included, suicide deaths may be underrecorded, and “adjusting for preexisting mental disorders could be viewed as overadjusting,” they wrote.
The study was supported by a grant from the Psychiatric Research Foundation in Denmark. The authors reported that they had no disclosures.

Two hours after treatment, a significantly greater proportion of patients who received the liquid solution, known as DFN-15, had freedom from pain and freedom from their most bothersome accompanying symptom – nausea, photophobia, or phonophobia – compared with patients who received placebo. The pain freedom rates were 35.6% with celecoxib oral solution and 21.7% with placebo. The rates of freedom from the most bothersome symptom were 57.8% with celecoxib oral solution and 44.8% with placebo.
About 9% of patients who received celecoxib oral solution had treatment-emergent adverse events related to the study drug, the most common of which were dysgeusia (4.2%) and nausea (3.2%). In comparison, about 6% of patients who received placebo had treatment-emergent adverse events. There were no serious treatment-emergent adverse events.
“DFN‐15 has the potential to become a reliable and convenient acute therapeutic option for patients with migraine,” said lead author Richard B. Lipton, MD, and colleagues. Dr. Lipton is affiliated with the Albert Einstein College of Medicine in New York.
Assessing celecoxib in migraineurs
Evidence-based guidelines recommend nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin, diclofenac, ibuprofen, and naproxen, as effective acute migraine treatments, but these medications may increase the risk of adverse gastrointestinal events, the authors said. Celecoxib, a selective cyclooxygenase (COX)-2 inhibitor, is indicated for the treatment of acute pain in patients with ankylosing spondylitis, osteoarthritis, primary dysmenorrhea, and rheumatoid arthritis. Although it produces analgesia similar to other NSAIDs, among patients with osteoarthritis and rheumatoid arthritis, celecoxib is associated with significantly lower risk of gastrointestinal events, compared with naproxen and ibuprofen, and significantly lower risk of renal events, compared with ibuprofen.
Researchers have studied an oral capsule form of celecoxib (Celebrex, Pfizer) as an acute treatment for migraine in an open-label study that compared celecoxib with naproxen sodium. “While preliminary results suggest comparable efficacy but better tolerability than widely used and guideline-recommended NSAIDs, celecoxib is not currently approved for migraine,” the authors said.
Compared with the oral capsule formulation, the oral liquid solution DFN-15 has a faster median time to peak concentration under fasting conditions (within 1 hour vs. 2.5 hours), which “could translate into more rapid onset of pain relief,” the authors said. In addition, DFN-15 may have greater bioavailability, which could lower dose requirements and improve safety and tolerability. To compare the efficacy, tolerability, and safety of 120-mg DFN-15 with placebo for the acute treatment of migraine, researchers conducted a randomized, double-blind, placebo-controlled study.
Participants used single-dose bottles
Researchers randomized 622 patients 1:1 to DFN-15 or placebo, and 567 treated a migraine during the trial. Patients had a mean age of 40 years, and 87% were female. Patients had episodic migraine with or without aura, no signs of medication overuse, and two-eight migraine attacks per month. For the trial, patients treated a single migraine attack of moderate to severe intensity within 1 hour of onset. “Each subject was given a single‐dose bottle of DFN‐15 120 mg or matching placebo containing 4.8 mL liquid,” Dr. Lipton and colleagues said. “They were instructed to drink the entire contents of the bottle to ensure complete consumption of study medication.”
Freedom from pain and freedom from the most bothersome symptom at 2 hours were the coprimary endpoints. “DFN‐15 was also significantly superior to placebo on multiple secondary 2‐hour endpoints, including freedom from photophobia, pain relief, change in functional disability from baseline, overall and 24‐hour satisfaction with treatment, and use of rescue medication,” they reported.
“A new COX‐2 inhibitor that is effective and rapidly absorbed could provide an important new option for a wide range of patients,” the authors said. “Though cross‐study comparisons are problematic, the current results for DFN‐15 indicate that its efficacy is similar to that of NSAIDs and small‐molecule calcitonin gene‐related peptide receptor antagonists (gepants), based on placebo‐subtracted rates pain freedom in acute treatment trials (14%‐21%). DFN‐15 may also be useful among triptan users, who are at elevated risk of medication‐overuse headache and for whom TEAEs within 24 hours postdose are common. ... The form and delivery system of DFN‐15 – a ready‐to‐use solution in a 4.8‐mL single‐use bottle – may support patient adherence.”
The trial had robust placebo response rates, which may have been influenced by “the novelty of a ready‐made oral solution, which has not been previously tested for the acute treatment of migraine,” the authors noted. In addition, the trial does not address the treatment of mild pain or treatment across multiple attacks.
The trial was supported by Dr. Reddy’s Laboratories, manufacturer of DFN-15. Two authors are employed by and own stock in Dr. Reddy’s. Dr. Lipton and a coauthor disclosed research support from and consulting for Dr. Reddy’s.
