Juvenile systemic lupus erythematosus in 60 Saudi children

A ten-year retrospective analysis of the clinical features and survival of 60 Saudi children with systemic lupus erythematosus (SLE) was made. All the patients fulfilled the 1982 American College of Rheumatology's revised criteria for SLE and had had the disease at or before the age of 16 years. The female to male ratio was 5:1, the mean age of onset was 12.1 years (range 1.6-16 years), and the mean duration of follow-up was 4.7 years (range 2.2-11). Thirty-eight patients (63%) were diagnosed correctly before referral to KFSH&RC or KKUH. The mode of presentation was as follows: 55 patients had musculoskeletal involvement (91.6%), 49 patients had skin involvement (81.6%), 40 patients had hematological abnormalities (66.6%), 39 patients had renal disease (65%), 10 patients had pulmonary involvement (16%), 23 patients had cardiovascular disease (38%) and 18 patients had central nervous system involvement. During the study period four patients died (6.6%) - two of renal failure, one from meningitis and one from severe sepsis. This is the largest collection of childhood systemic lupus erythematosus from the Middle East and it shows that SLE is more common in Saudis than was hitherto believed, and that it has a high rare of organ involvement.
