title: Neonatal hemolytic uremic syndrome after mother-to-child transmission of Escherichia coli O157.
abstract: About 90% of cases of hemorrhagic uremic syndrome (HUS) occur in early childhood and most frequently are preceded by bloody diarrhea due to shiga-like toxin (SLT) producing Escherichia coli. We report a case of a newborn girl presenting with bloody diarrhea on her 7th day of life. Acute renal failure, severe arterial hypertension and hemolytic anemia were detected and prompt peritoneal dialysis and antihypertensive therapy were required. The girl had several episodes of seizures, necessitating intravenous phenobarbital. Transfontanel ultrasonography 48 h after disease onset was normal, whereas, MRI investigation 10 days later revealed severe ischemic lesions with beginning cystic encephalopathy. Renal function recovered and only very moderate tubular dysfunction remained. Serum analysis of factor H, von Willebrand factor protease, homocystinemia, proteins C and S, and antithrombin III were all normal. Mutation analysis of factor V Leiden, factor II, and methyltetrahydrofolate-reductase were normal. E. coli 0157:H7 and SLT 2 were detected in the stool. SLT 2 was also found in the mother's stool. This is the first report of mother-to-child transmission of SLT-producing E. coli.
