Obstructive Sleep Apnea Common But Often Undiagnosed, Leading to Treatment Delay, Study Suggests
People with fibromyalgia are very commonly diagnosed with obstructive sleep apnea, highlighting the importance of sleep studies for better management of the condition, researchers from Loyola University Chicago report. The review study, “Obstructive sleep apnea co-morbidity in patients with fibromyalgia: a single-center retrospective analysis and literature review,” was published in the journal Rheumatology: Research and Reviews. Improving sleep patterns and sleep quality is vital in the symptomatic management of fibromyalgia. Sleep disturbance, and specifically obstructive sleep apnea (OSA), is prevalent in fibromyalgia patients, but often undiagnosed. This causes a delay in treatment, as well as "leading to medical and economic consequences," the researchers said. Determining the rate of co-morbidity — or the co-occurrence — of fibromyalgia and OSA will help to improve the treatment and management of fibromyalgia, according to the study. The team searched the Loyola University Chicago health system medical records and identified patients, 18 years and older, diagnosed with fibromyalgia and OSA from 2012 to 2016. They then determined the overlap between the two diagnoses. The researchers assessed clinical data from all outpatient clinics in the system, including psychiatry, sleep, and rheumatology. Among the total number of patients in each clinic, the greatest number of fibromyalgia patients — 2,505 of 8,607, or 29.1% — were identified in the rheumatology clinic. Next was the sleep clinic (1,205/6,975; 17.2%), followed by psychiatry (364/2,393; 15.2%), and other clinics (15,106/380,666; 3.9%). The majority (14,833) of all those diagnosed with fibromyalgia (19,180) were women. Further review showed that, among those with fibromyalgia
