Background Narcolepsy is a rare, central disorder of hypersomnolence that requires long-term treatment and is associated with multiple comorbidities. Many treatments for narcolepsy symptoms have cardiovascular-related warnings and precautions in their labels.

Objective To estimate the risk of cardiovascular and renal comorbidities in US adults with narcolepsy.

Design/Methods Claims from IBM^® MarketScan^®, an administrative claims database, between January 2014 and June 2019 were analyzed. Eligible patients were ≥18 years of age and had continuous medical and prescription coverage (gaps ≤30 days allowed). The narcolepsy cohort was defined by ≥2 outpatient claims containing a diagnosis of narcolepsy type 1 or type 2 on separate days and no more than 6 months apart, with ≥1 non-diagnostic office visit. Patients without narcolepsy were matched 3:1 to patients with narcolepsy by calendar date of cohort entry, age, gender, US geographic region, and insurance type. Each incidence calculation required a 6-month washout period prior to cohort entry. Differences between cohorts were evaluated using a Cox proportional hazard model adjusted for age, gender, region, insurance type, and relevant morbidities/comorbidities and medications in the baseline period.

Results

Of 54,239,110 adults in the database, 12,816 and 38,441 were included in the narcolepsy and matched non-narcolepsy cohorts. Approximately 67% were female, and mean age was approximately 38 years in both cohorts. Adjusted hazard ratios (HRs), derived from incidence rates, suggested significantly increased risk of the following outcomes in the narcolepsy cohort compared with matched non-narcolepsy controls (nominal P<0.05): any stroke (HR [95% CI]: 1.71 [1.24, 2.34]); edema (1.61 [1.28, 2.03]); heart failure (1.35 [1.03, 1.76]); ischemic stroke (1.67 [1.19, 2.34]); major adverse cardiac event (1.45 [1.20, 1.74]); grouped instances of stroke, atrial fibrillation, or edema (1.48 [1.25, 1.74]); and any cardiovascular disease excluding hypertension (1.30 [1.08, 1.56]).

Conclusions Physicians should consider increased cardiovascular risk when weighing risk modification strategies and treatment options for narcolepsy.
