Systemic lupus erythematosus in Kuwait--hospital based study

Abstract

The present study describes the clinical characteristics of patients with systemic lupus erythematosus (SLE), from the rheumatology service of the two main teaching hospitals in Kuwait. It was a retrospective-cum-prospective clinical study of 108 SLE patients. There were 98 females and 10 males, with a median age of 31.5y. Kuwaitis constituted 69%, while 31% were expatriates. The mean disease duration was 62 months. The main clinical features were: musculoskeletal involvement (87%), photosensitivity (48%), malar rash (43%), discoid lesions (10%), oral ulcers (33%), vasculitic skin lesions (10%), haematological features (53%), constitutional symptoms (51.4%), neuropsychiatric manifestations (23%), renal involvement (37%), serositis (29%), clinical manifestations of antiphospholipid syndrome (21%), cardiac involvement (10%) and pulmonary manifestations (19%). In conclusion, the clinical features of SLE in Kuwait were similar to most major studies from developed countries. Main differences included prominent haematological and mucocutaneous manifestations and possibly a low prevalence of anti-Sm antibodies. Whether these differences are due to the environment or genetic factors, remains to be studied.
