[Hemolytic-uremic syndrome in children: a 19-year retrospective study].

Forty-two children (22 girls and 20 boys, ranging in age between 2 months and 13 years, median age 17 months) were admitted with acute hemolytic-uremic syndrome to the University Children's Hospital, Berne from 1973 to 1991. Seventeen patients developed hypertension and 30 renal failure. Three out of the 19 cases necessitating acute dialysis progressed to end stage renal failure. Four out of the 7 patients with signs of severe central nervous system involvement died. The initial clinical course was consistently more favourable in 35 patients with diarrheal prodrome. Increased protein excretion in association with high blood pressure was observed in 4 patients with initial favourable course who were examined one year after disease onset. This study indicates the generally favourable immediate prognosis of childhood hemolytic uremic syndrome and the possible persistence of high blood pressure and pathological proteinuria on follow-up.
