The observation of several cases with coexistent antiphospholipid syndrome (APS) and fibromyalgia led us to this investigation. The objective was to define the frequency of fibromyalgia in a group of patients with antiphospholipid syndrome.
From March 24th to June 8th 2017 we studied all APS patients attending our outpatient rheumatology clinic. All of them fulfilled the Sapporo and/or Sydney APS classification criteria. The Institutional Ethics Committee approved the protocol. All patients underwent a history + physical examination with emphasis on musculoskeletal features. All filled-out the following questionnaires: the Revised Fibromyalgia Impact Questionnaire (FIQ-R), the 2016 revision of Wolfe’s Fibromyalgia Diagnostic Criteria, and the quality of life EuroQol 5D-5L. The Damage Index in Thrombotic Antiphospholipid Syndrome (DIAPS) was also obtained. Spearman method was used to correlate APS clinical features with fibromyalgia questionnaire scales. Chi square to compare categorical variables.
Sixty one patients with APS were included. Their mean age: 44 ± 15 years, 70% are female and 54% have primary APS. The prevalence of fibromyalgia was different when using the 1990 ACR diagnostic criteria (4.9%) compared to Wolfe’s criteria (16.4%) p<0.0001. The frequency of fibromyalgia was not different in patient with primary vs. secondary APS. In those patient who had concurrent APS and fibromyalgia according to Wolfe’s criteria (n = 10), there was a correlation between total number of thrombotic events with headache, depression, and abdominal pain (r=0.636, p=0.048), as well as with FIQ-R balance problems (r=0.754, p=0.012). Oddly, cumulative organ damage measured by DIAPS inversely correlated with FIQ-R quality of sleep (r=-0.820, p=0.004). Quality of life measured by Euro Qol is poorer in APS + fibromyalgia patients (85±16 vs 64±12, p<0.001).
In this cohort of patients with APS, more individuals can be classified as having concurrent fibromyalgia when the 2016 revised Wolfe’s criteria is used. Recurrent thrombosis is associated to several fibromyalgia symptoms such as headache, depression and abdominal pain. Patients with APS and concurrent fibromyalgia have poorer quality life.
