Systemic lupus erythematosus in Kuwaiti children: organ system involvement and serological findings

Abstract

The course and severity of systemic lupus erythematosus (SLE) in children is generally similar to the adult form with potential serious organ system involvement, there are, however, factors that influence the prevalence and clinical behavior of the disease. Our objective was to analyse the organ system involvement and immunological findings in Kuwaiti children with SLE in relation to gender and age of onset and compare these findings to that in published reports. Organ system involvement and serologic profiles were analysed in 35 children with SLE. The major organ systems studied were: renal, hematological, cardiac, pulmonary, hepatic and the central nervous system. The prevalence of ANA, anti-dsDNA, anti-Sm, SSA, SSB and anti-cardiolipin antibodies were studied in addition to complement C3 and C4 levels. The results showed that a high percentage of children had hematological involvement (34%); thrombocytopenia (23%) and hemolytic anemia (20%). Renal involvement was proven by biopsy in only 10 children (29%). Neuropsychiatric manifestations were seen in five (14%) of patients. Males had a tendency for major organ involvement relative to females. All patients had positive ANA tests. All males had positive anti-dsDNA tests compared to 86% of female patients. The most significant finding in this study is the high frequency of hematological manifestations and the relatively low incidence of renal disease and neuropsychiatric abnormalities in Kuwaiti children with SLE.
