[Systemic lupus erythematosus: description of a pediatric series].
We describe 11 cases of Systemic Lupus Erythematosus (SLE) with pediatric onset (10 females and 1 male). Mean age at onset was 10.9 years (range 3 to 16 years). Initial manifestations: cutaneous involvement in 7 cases, articular symptoms in 7 cases, renal involvement in 5 cases (proteinuria and/or microhematuria, or renal failure), pancytopenia in 3 cases. In 3 cases the onset of the disease was extremely sudden and severe: one patient had an intestinal infarct following mesenteric thrombosis associated with glomerulonephritis; another started with encephalopathy (deep coma, stage III); a third patient presented renal failure due to acute glomerulonephritis. At diagnosis all patients received systemic steroid therapy with the exception of one who had only a cutaneous involvement. The course of the disease is described. We underline that, in our series, it was rare for organs and systems, apart from the central nervous system, to be involved in exacerbations after initial onset of the disease. Six patients are presently asymptomatic or have only minor cutaneous and/or articular manifestations which are well controlled with low-dose cortisone therapy. Laboratory indices did not return to normal in any of the patients. In fact, in our series the disease doesn't appear to reach a complete remission, even many years after onset and no patient seems to be able to withdrawal the therapy at all. Our data confirm, according to other Authors, that the course of LES with paediatric onset is more severe than in adults.
