What Is the Prevalence of Sleep Disorders in Neurologic Populations?

Article Type
Changed

A retrospective study finds that insomnia may be associated with worse neurologic status in patients with movement disorders and patients with epilepsy.

LOS ANGELES—About one-third of neurologic patients has a high risk of obstructive sleep apnea (OSA), and approximately one-quarter has significant symptoms of insomnia, according to data presented at the 70th Annual Meeting of the American Academy of Neurology. The presence of insomnia symptoms is associated with worse neurologic status in movement disorders and epilepsy populations, researchers said.

“Given the high prevalence of sleep disorder symptoms, further investigation into the role of sleep therapies on disease-specific outcomes in neurologic populations is warranted,” said Thapanee Somboon, MD, a neurologist at Prasat Neurological Institute in Bangkok, Thailand, and research fellow at the Cleveland Clinic Sleep Disorders Center, and colleagues.

Analyzing STOP and Insomnia Severity Index Scores

OSA and insomnia are highly prevalent in the general population and may be more common in patients with neurologic conditions. To examine the association between sleep instrument scores and disease-specific outcomes in neurologic populations, Dr. Somboon and colleagues conducted a retrospective analysis of data from 19,052 adult initial visits to the psychiatry, brain tumor, movement disorders, cerebrovascular, and epilepsy centers at the Cleveland Clinic between March 2015 and October 2016.

In all, 7,762 patients had completed the snoring, tiredness, observed apnea, and high blood pressure (STOP) questionnaire, and 8,530 patients had completed the Insomnia Severity Index. A STOP score of 2 or greater predicted a high risk of OSA, and an Insomnia Severity Index score of 15 or greater indicated significant insomnia symptoms.

The crude prevalence of high-risk OSA was 47.9% in the cerebrovascular center, 44.1% in the movement disorders center, 34% in the brain tumor center, 33% in the epilepsy center, 29.8% in the psychiatry center, and 36.7% overall.

The crude prevalence of significant insomnia symptoms was 33.6% in the psychiatry center, 26.1% in the epilepsy center, 20.7% in the brain tumor center, 20% in the movement disorders center, 19.5% in the cerebrovascular center, and 25.5% overall.

Disease-Specific Outcomes

The researchers used regression models to adjust for patients’ age, sex, race, marital status, self-reported sleep duration, income, tobacco use, and comorbid conditions. Multivariate models evaluated the associations between abnormal sleep scores and scores on the Patient Health Questionnaire-9 (PHQ-9; from all centers), Karnofsky Performance Status (from the brain tumor center), Unified Parkinson’s Disease Rating Scale (UPDRS II; from the movement disorders center), modified Rankin Scale (from the cerebrovascular center), and Liverpool Seizure Severity Scale (from the epilepsy center).

Patients with a STOP score of 2 or greater were older, more likely to be male, more likely to be a current or former smoker, had greater PHQ-9 scores, and had more comorbidities.

Patients with Insomnia Severity Index scores of 15 or greater were younger, more likely to be female, more likely to be a current or former smoker, and had a higher prevalence of depression.

OSA and insomnia were significantly associated with PHQ-9 scores. In addition, insomnia symptoms were significantly associated with Liverpool Seizure Severity Scale and UPDRS II scores.

Sleep Paralysis and Hallucinations Are Prevalent in Student Athletes

Article Type
Changed

These symptoms may predict depression severity, independent of short sleep and insomnia.

BALTIMORE—Many student athletes have sleep paralysis and hypnagogic or hypnopompic hallucinations, according to research presented at the 32nd Annual Meeting of the Associated Professional Sleep Societies. In addition, these sleep symptoms are independently associated with symptoms of depression.

“These sleep symptoms are usually harmless on their own, but they can be a sign of more serious sleep problems,” said Serena Liu, a student research assistant in the Sleep and Health Research Program at the University of Arizona College of Medicine in Tucson. “The fact that they are so common among student athletes suggests that this is a group with some significant sleep problems that should be evaluated and dealt with.”

A Study of NCAA Athletes

Student athletes often have difficulty finding time to rest because of their busy schedules. Shorter sleep duration and poor sleep quality contribute to disordered sleep in many student athletes, and data indicate a high prevalence of common sleep symptoms in this group. Investigators have not studied the prevalence of less common symptoms (eg, sleep paralysis and hypnagogic and hypnopompic hallucinations, which are more prevalent in younger adults) in student athletes, however. Nor have they examined the potential role of these symptoms in mental health, independent of insufficient sleep duration or insomnia.

Ms. Liu and colleagues collected data from 189 student athletes in the National Collegiate Athletic Association’s Division I. The researchers asked the athletes how often they had sleep paralysis and hypnagogic or hypnopompic hallucinations. Responses were “never,” “rarely (once per month or less),” or “often (once or more per week).” Participants also gave information about sleep duration and underwent evaluation with the Insomnia Severity Index and the Centers for Epidemiological Studies Depression Scale. Ms. Liu and colleagues performed regression analyses to examine depression score as outcome and sleep symptoms as predictor in a model adjusted for age and sex and a model adjusted for age, sex, insomnia severity, and sleep duration.

Sleep Symptoms May Indicate Other Problems

About 18% of the sample reported having sleep paralysis rarely, and 7% reported having it often. In addition, 24% of the sample reported having hypnagogic or hypnopompic hallucinations rarely, and 11% reported having them often. In models adjusted for age and sex, reporting sleep paralysis rarely and often were associated with higher depression score, compared with reporting them never. Similarly, reporting hypnagogic and hypnopompic hallucinations rarely and often were associated with higher depression score. In models adjusted for insomnia and sleep duration, these relationships were attenuated, but remained significant.

High-Intensity Interval Exercise May Be Appropriate for Patients With MS

Article Type
Changed

The activity is as enjoyable as continuous exercise for this population and could improve physiologic conditioning.

NASHVILLE—For patients with multiple sclerosis (MS) and walking impairments, high-intensity interval exercise is as enjoyable as traditional continuous exercise and does not induce sustained, harmful effects on mood, according to research presented at the 2018 CMSC Annual Meeting. This finding could influence evidence-based prescriptions for exercise that are appropriate for improving physiologic conditioning, according to the researchers.

MS often results in walking dysfunction and physiologic deconditioning. High-intensity interval exercise has induced significant improvements in physiologic conditioning in healthy and clinical populations, including patients with MS. Before integrating high-intensity interval exercise into an exercise prescription, and to increase the likelihood that participants will engage in and adhere to this exercise regimen, investigators thought it important to ascertain whether people with MS and mobility disability enjoy the high-intensity interval exercise and experience mood benefits.

Elizabeth Hubbard, PhD, Assistant Professor of Kinesiology at Berry College in Mount Berry, Georgia, conducted a study to examine the effects of single sessions of high-intensity interval exercise and continuous exercise on mood and enjoyment outcomes in persons with MS and mobility disability. In their study, 20 participants (median Expanded Disability Status Scale score, 5.8) underwent counterbalanced presentations of high-intensity interval exercise and continuous exercise bouts using a recumbent stepper. The high-intensity interval exercise bout was 20 minutes long and included 10 cycles of one-minute intervals at a wattage associated with 90% VO2 peak, followed by one-minute recovery intervals at 15 W. The continuous exercise bout lasted for 20 minutes at a wattage associated with 50% to 60% VO2 peak. The researchers administered the Profile of Mood States (POMS) survey before, immediately after, and 30 minutes after exercise. The Physical Activity Enjoyment Scale (PACES) questionnaire was administered immediately after exercise.

Elizabeth Hubbard, PhD


Dr. Hubbard and colleagues observed no significant condition-by-time interactions or main effects of condition on any POMS subscales. The data indicated large, statistically significant main effects of time on total mood disturbance, fatigue, and vigor. Specifically, mood worsened immediately after exercise, but rebounded after the 30-minute recovery period. The researchers saw no significant difference in scores for the PACES questionnaire between high-intensity interval exercise (mean, 95.5) and continuous exercise (mean, 97.7) conditions.

One weakness of the study was that the population was relatively active, although with a low level of fitness. In addition, the researchers did not control for age, sex, or disability status.

The high-intensity interval exercise and continuous exercise were feasible, safe, and enjoyable in people with MS who have mobility disability. “High-intensity interval exercise … might be particularly beneficial for improving fitness and functional capacity in persons with MS who have mobility disability and experience subsequent physiologic deconditioning,” said Dr. Hubbard.

How does the Quality Payment Program affect you?

Article Type
Changed

 

AGA asks Congress and CMS to continue to implement the Quality Payment Program (QPP) in a way that maximizes flexibility and success for you and your Medicare patients.

Most gastroenterologists participate in the Merit-Based Incentive Payment System (MIPS), which means how the QPP is implemented impacts the entire GI profession. The QPP replaced the sustainable growth rate (SGR) formula in 2015 when the Medicare Access and CHIP Reauthorization Act (MACRA) was signed into law. The QPP is comprised of two tracks: MIPS and Advanced Alternative Payment Models (Advanced APMs).

CMS has designated 2017 and 2018 as transition years to allow providers to learn about the QPP and to gradually increase their preparedness for MIPS.

Congress also recently acted to provide CMS additional flexibility with respect to QPP and MIPS implementation, including:

• Excluding Medicare Part B drug costs from MIPS payment adjustments.

• Eliminating improvement scoring for the cost performance category for the second through fifth years of MIPS.

• Allowing CMS to weight the cost performance category at less than 30 percent, but not less than 10 percent for the second through fifth years of MIPS.

• Allowing CMS flexibility in setting the performance threshold for MIPS in years two through five to ensure a gradual and incremental transition to the performance threshold set at the mean or median for the sixth year.

QPP implementation is a top priority for AGA to ensure that the value of specialty care is recognized. Learn more on our website www.gastro.org/QPP.

Phase 3 trial: Tasimelteon effective for jet lag disorder

Article Type
Changed

 

– Tasimelteon, a drug approved for non–24-hour sleep-wake disorder, has been shown to increase sleep times in travelers with jet lag, according to results from a phase 3 trial.

“Tasimelteon demonstrated an increase in total sleep time of 85 minutes versus placebo and also demonstrated improvement in next-day alertness versus placebo,” Christos Polymeropoulos, MD, medical director of Vanda Pharmaceuticals, said in presenting results of the JET8 trial during the late-breaking abstracts session at the annual meeting of the Associated Professional Sleep Societies.

Tasimelteon, sold under the trade name Hetlioz, is a melatonin receptor agonist that is Food and Drug Administration–approved for non-24-hour sleep-wake disorder – but not for treatment of jet lag disorder (JLD). Dr. Polymeropoulos noted there is no FDA-approved treatment for JLD.

“Jet lag disorder is a circadian disorder frequently observed in millions of travelers who cross multiple time zones,” Dr. Polymeropoulos said. “JLD is characterized by nighttime sleep disruption, decrease in daytime alertness, and impairment in social and occupational function.”

JET8 induced the circadian challenge equivalent to crossing eight time zones. The study involved 318 individuals randomized evenly to 20 mg tasimelteon or placebo 30 minutes before bedtime. The primary endpoint of the study was total sleep time in the first two-thirds of night measured by polysomnography.

Those on tasimelteon averaged 216.4 minutes of total sleep time in the first two-thirds of night versus 156.1 for those on placebo (P less than .0001), Dr. Polymeropoulos said. Full total sleep times were 315.8 minutes versus 230.3 minutes (P less than .0001), respectively.

“For total sleep time, the tasimelteon subjects gained about an hour and a half, as measured by PSG [polysomnography],” Dr. Polymeropoulos said.

Other key markers the trial measured were latency to persistent sleep and wakefulness after sleep onset. They measured 15 minutes less and 74.6 minutes less, respectively, in the tasimelteon arm.

Dr. Polymeropoulos also disclosed early results of a second trial of tasimelteon in JLD: the JET Study, a two-phase transatlantic travel study of 25 patients. The subjects flew from four U.S. cities to London for 3 nights, receiving tasimelteon or placebo each night in London. The study was terminated before reaching its enrollment goal of 90 patients because of its complexity, Vanda said in a separate press release. Over 3 nights of study, the tasimelteon arm gained a total of about 130 minutes of sleep versus 40 minutes for the placebo arm, Dr. Polymeropoulos said.

Vanda has said it plans to file a supplemental new drug application for tasimelteon for treatment of JLD in the second half of this year.

Study questions canagliflozin amputation risk, but concerns remain

Article Type
Changed

A large, observational study found no increased risk of below-the-knee amputations with canagliflozin (Invokana) for type 2 diabetes, but clinicians should still favor other options in patients at risk for amputations, according to investigator John Buse, MD, PhD, chief of the division of endocrinology at the University of North Carolina at Chapel Hill.

Canagliflozin is the only sodium-glucose transporter 2 (SGLT2) inhibitor that carries a black box warning of “lower limb amputations, most frequently of the toe and midfoot” but also the leg. The drug doubled the risk versus placebo in its approval trials, particularly in patients with baseline histories of prior amputations, peripheral vascular disease, neuropathy, or diabetic foot ulcers.

One trial, for instance, reported 7.5 amputations per 1,000 patient years versus 4.2 with placebo, according to labeling.

The new, observational study, which was funded by canagliflozin’s maker Johnson & Johnson and, with the exception of Dr. Buse, conducted by its employees, found no such connection. Investigators reviewed claims data from 142,800 new users of canagliflozin, 110,897 new users of the competing SGLT2 inhibitors empagliflozin (Jardiance) and dapagliflozin (Farxiga), and 460,885 new users of other diabetes drugs except for metformin, Dr. Buse said when he presented the results at the annual scientific sessions of the American Diabetes Association.

The hazard ratio for below-knee amputations with canagliflozin versus non-SGLT2 inhibitors was 0.75 (95% confidence interval, 0.40-1.41; P = 0.30). The ratio versus other SGLT2 inhibitors was 1.14 (95% CI, 0.67-1.93; P = 0.53). Overall, there were 1-5 amputations per 1,000 patient years with the drug.

However, the median follow-up was a few months, far shorter than the median follow-up of over 2 years in the randomized trials. “Therefore, the current study had limited statistical power to detect differences in the 6-12 month time period, the time at which amputation risk began to emerge” in the trials, the study report noted. Also, the investigators didn’t parse out results according to baseline amputation risk. Overall, “none of the analyses were sufficiently powered to rule out the possibility of a modest effect” on amputation rates (Diabetes Obes Metab. 2018 Jun 25. doi: 10.1111/dom.13424).

When moderator Robert H. Eckel, MD, a professor in the division of endocrinology, metabolism, and diabetes at the University of Colorado at Denver, Aurora, asked the 150 or so people who heard the presentation if they use SGLT2 inhibitors in their practices, only a small number raised their hands. Few, if any, raised their hands when he asked if the new results would make them more comfortable prescribing canagliflozin.

“I find [the study] somewhat informative,” Dr. Eckel said in an interview afterwards, “but I think the issue is that the prescribing label still demands that patients be informed of the black box warning. I think we are going to have to wait for the longer term outcomes to determine if [amputation] is a molecule effect or a class effect.”

Dr. Buse later said that “I think for the general population of patients with diabetes, they are at low risk for an amputation,” but “if you are at high risk for having an amputation, we really have to take this risk very seriously. [Canagliflozin] may increase your risk for amputation.

“If I have a patient who has had an amputation and I want to use an SGLT2 inhibitor, I wouldn’t use canagliflozin because of the label. I would use empagliflozin because [amputation] is not in the label, and there was no evidence” of it in trials, he added.

The new study, meanwhile, confirmed the cardiac benefits of SGLT2 inhibitors in type 2 patients. Canagliflozin, for instance, reduced the risk of hospitalization for heart failure by about 60%, compared with non-SGLT2 inhibitors in patients with cardiovascular disease, but it offered no statistically significant heart benefit over other members of its class.

FDA approves Aristada Initio for schizophrenia

Article Type
Changed

 

The Food and Drug Administration has approved aripiprazole lauroxil (Aristada Initio) for the initiation of aripiprazole lauroxil (Aristada) for treating schizophrenia in adults, the drug’s developer, Alkermes, announced July 2 in a press release.

The alternative formulation of the long-acting injectable is intended be used with a single 30-mg dose of oral aripiprazole and can be initiated on the first day of treatment, Alkermes stated.

The ability to initiate Aristada on day one may be particularly useful in the hospital setting, where more than one-third of patients initiate onto long-acting therapies,” Craig Hopkinson, MD, chief medical officer at Alkermes, said in the press release.

The standard initiation regimen for aripiprazole lauroxil previously was 21 consecutive days of oral aripiprazole starting with the first dose of Aristada. The alternative initiation regimen allows patients to achieve “relevant levels of aripiprazole within 4 days of initiation,” according to Alkermes. The result gives health care providers “an additional tool to support patients.”

One important advantage of Aristada Initio is that, in addition to monthly and 6-week dosing options, it offers a 2-month option.

Aristada and Aristada Initio both contain aripiprazole lauroxil, but the drugs are not interchangeable because they have different pharmacokinetic profiles, the company said. In addition, Aristada Initio is to be administered a single time only.

Aristada Initio has exhibited some of the same adverse events as other atypical antipsychotics, including neuroleptic malignant syndrome, tardive dyskinesia, and metabolic changes. Injection-site reactions also have been observed.

Aristada Initio is expected to become available by mid-July.

Full prescribing information and boxed warnings can be found on the Alkermes website.

Aristada and Aristada Initio both contain aripiprazole lauroxil, but the drugs are not interchangeable because they have different pharmacokinetic profiles, the company said. In addition, Aristada Initio is to be administered a single time only.

Aristada Initio has exhibited some of the same adverse events as other atypical antipsychotics, including neuroleptic malignant syndrome, tardive dyskinesia, and metabolic changes. Injection-site reactions also have been observed.

Aristada Initio is expected to become available by mid-July.

The Food and Drug Administration has approved aripiprazole lauroxil (Aristada Initio) for the initiation of aripiprazole lauroxil (Aristada) for treating schizophrenia in adults, the drug’s developer, Alkermes, announced July 2 in a press release.

The alternative formulation of the long-acting injectable is intended be used with a single 30-mg dose of oral aripiprazole and can be initiated on the first day of treatment, Alkermes stated.

The ability to initiate Aristada on day one may be particularly useful in the hospital setting, where more than one-third of patients initiate onto long-acting therapies,” Craig Hopkinson, MD, chief medical officer at Alkermes, said in the press release.

The standard initiation regimen for aripiprazole lauroxil previously was 21 consecutive days of oral aripiprazole starting with the first dose of Aristada. The alternative initiation regimen allows patients to achieve “relevant levels of aripiprazole within 4 days of initiation,” according to Alkermes. The result gives health care providers “an additional tool to support patients.”
