title: Clinical features of systemic lupus erythematosus in Thai males and females.
abstract: From 1976 through 1988, 726 patients with systemic lupus erythematosus (SLE) were admitted to the Medical Service of Chulalongkorn Hospital, 666 cases (91.7%) being female and 60 cases (8.3%) male (the female-to-male ratio = 11:1). Clinical comparison of 60 males and 130 females (by randomized selection from the total of 666 females) was made. Onset of disease in males occurred later than in females (29.2 +/- 12.2 years vs 25.8 +/- 10.7 years, p less than 0.01). The majority of clinical manifestations were similar; however, musculoskeletal (63.3 vs 73.3%), cardiac manifestations (13.3 vs 26.1%) and Raynaud's phenomenon (18.3 vs 35.4%) were less common in males than females (p less than 0.01), whereas hematologic manifestations were more common in males than females (p less than 0.01).
