[Hemolytic uremic syndrome following juvenile lupus erythematodes disseminatus]

A 12.5 year old girl was admitted to hospital with the typical signs of hemolytic uremic syndrome, and systemic lupus erythematodes as well. On the basis of clinical, blood chemistry, and histological findings we assumed an hemolysis-induced form of hemolytic-uremic syndrome as the most likely pathogenic mechanism. The child also suffered from congenital IgA-deficiency and produced an inhibitor against coagulation factor VIII. Congenital IgA-deficiency, systemic lupus erythematodes, inhibitor-induced hemophilia and hemolytic uremic syndrome are suggested to form a pathogenic sequence.
