    Description / Table of Contents: Summary A 139/12 year old boy presented with the clinical and laboratory signs of a systemic lupus erythematosus (SLE)-like illness. Three months later he developed acute renal failure associated with hemolytic anemia and thrombocytopenia while being treated with prednisone and a non-steroidal antiphlogistic agent. Kidney biopsy revealed endotheliotropic microangiopathy. A thrombocytopenic purpura/hemolytic uremic syndrome was diagnosed according to clinical and histological findings. Plasma exchange, hemodialysis and immunosuppressive therapy with prednisone and cyclophosphamide resulted in a normalization of the hematologic findings, and the kidney function improved. The cyclophosphamide therapy was continued over 21/2 years. Three years after the acute episode the boy is free of symptoms with glomerular filtration rate of 71 ml/min/1.73 qm. Discussion. The association of SLE with thrombotic thrombocytopenic purpura is rare, has predominantly been described in adults and has a high mortality rate. Our case demonstrates the success of an early aggressive therapy including plasma exchange, hemodialysis, prednisolone and cyclophosphamide.
    Notes: Zusammenfassung Ein 139/12 Jahre alter Knabe entwickelte 3 Monate nach Beginn einer Lupus-ähnlichen Systemerkrankung unter Prednisontherapie ein akutes Nierenversagen mit hämolytischer Anämie und Thrombozytopenie. Die Nierenbiopsie zeigte eine thrombotische Mikroangiopathie. Unter Behandlung mit Plasmaaustausch, immunsuppressiver Therapie und Hämodialyse normalisierten sich die hämatologischen Befunde, und die Nierenfunktion besserte sich. Die Cyclophosphamidtherapie wurde über 21/2 Jahre fortgesetzt. Drei Jahre nach dem akuten Nierenversagen ist der Junge unter antihypertensiver Behandlung symptomfrei und hat eine normale glomeruläre Filtrationsrate. Diskussion. Die Assoziation eines systemischen Lupus erythematodes mit einer thrombotisch-thrombozytopenischen Purpura ist in der Literatur bisher nur selten und fast nur bei Erwachsenen beschrieben worden; sie hat eine hohe Mortalität. Der dargestellte Fall demonstriert den Erfolg einer frühzeitigen aggressiven Therapie.

    Notes: Abstract  We studied the long-term outcome of 64 children with biopsy-proven Schönlein-Henoch purpura (SHP) nephritis over 1–23 years of follow-up. Overall renal survival 10 years after onset was 73%. Multivariate logistic regression analysis identified initial renal insufficiency (P=0.004), nephrotic syndrome (P=0.037), and the severity of histological alterations, as defined by the proportion of glomerular crescents (P=0.051), as significant independent predictors of progressive renal failure. Four patients followed for more than 19 years showed glomerular damage after transient recovery. Eight children with crescentic nephritis associated with a rapidly progressive course and/or persistent nephrotic syndrome were treated by at least seven sessions of plasma exchange (PE) within 16 weeks of onset of purpura. During treatment serum creatinine levels dropped in each patient from a mean of 2.3 to 1.1 mg/dl, followed by a rebound increase. Repeated courses of PE in 5 patients produced comparable responses. Four patients undergoing PE reached end-stage renal disease at 1.2.–3.7 years after onset, whilst 3 finally were in preterminal renal failure (creatinine 3.2–6.1 mg/dl after 7–13.5 years), and 1 patient reached a normal glomerular filtration rate. Our experience suggests that initial renal insufficiency is the best single predictor of the further clinical course in children with SHP nephritis. Early PE appears to delay the progression in some patients with severe, rapidly progressive forms of the disease.
