Hemolytic uremic syndrome in childhood: renal function ten years later.

Forty-six patients who developed a Hemolytic Uremic Syndrome (HUS) during the period 1970-1976, were examined ten years later. Thirty-two individuals had no signs of renal disease whereas fourteen showed at least one abnormality. In the latter group a urinary osmolality below 800 mosmole per kg water was the most frequent defect found (eight cases). Three adolescents had both hypertension and proteinuria, which are considered as important late sequelae.
