Prognosis of Streptococcus pneumoniae-induced hemolytic uremic syndrome

Abstract  

Streptococcus pneumoniae-induced hemolytic uremic syndrome (HUS) is known to be a severe acute disease leading to death in one-third of cases, but data regarding the long-term follow-up are lacking. A new series of 11 patients with Streptococcus pneumoniae-induced HUS associated with meningitis and pneumonia constituted a multi-center review. Among 9 patients with a severe acute infectious disease, 3 died from meningitis and 1 from neurological sequelae after a partial recovery of renal function. The mean duration of dialysis was 32 days in patients with acute renal failure who survived the acute infectious period. Cortical necrosis was documented in five of six kidney specimens. Among the 7 surviving patients, 5 developed end-stage renal failure 4–17 years later.
