Health-related quality of life impairment is equal for antiphospholipid syndrome whether primary or associated with systemic lupus erythematosus.

INTRODUCTION

Antiphospholipid syndrome (APS) manifests with thrombosis and pregnancy losses and may significantly impair the health-related quality of life (HRQoL). So far, APS has been perceived as a less burdensome disease than systemic lupus erythematosus (SLE), but data on this are scarce. The purpose of the present study was to evaluate HRQoL in APS patients by applying the Short Form 36 Health Survey (SF-36) and World Health Organization Quality-of-Life Scale (WHOQoL-BREF); to examine the impact of primary APS and with coexisting SLE (APS/SLE) on patient HRQoL; and to provide a description of the APS patient population.

MATERIAL AND METHODS

One hundred twelve patients with APS were included in the study, 57 of them with primary APS and 55 with coexisting SLE. HRQoL was measured by the 36-Item SF-36 and WHOQoL questionnaires.

RESULTS

Mean age was 47 years (47.6 ±13.8), and 96 patients were (85.7%) women. The mean disease duration was 72 months. Health-related quality of life impairment was found in both components for all APS patients in comparison to the healthy Polish population ( < 0.0001). There was no difference between APS and APS/SLE groups in HRQoL (mental component = 1.0, physical component = 0.337). The history of venous thrombosis was associated with HRQoL impairment only in the APS/SLE group in the physical component ( = 0.0118), not in primary APS ( = 0.6862). The mental component of SF-36 was associated with all domains of WHOQoL-BREF, while the physical component was associated only with physical health ( < 0.001).

CONCLUSIONS

Primary APS and APS secondary to SLE lead to equal impairment in HRQoL. Diagnosis and proper management of all patients with APS are essential to prevent thrombosis and miscarriages, which ultimately will lead to longer survival with optimal life quality.
