Microangiopathic anemia without thrombocytopenia and kidney disease in a child with diarrhea caused by Shiga toxin-producing Escherichia coli.

A child with a history of diarrhea presented with transient anemia, reticolucytosis, and red blood cell fragmentation. Blood pressure and levels of blood platelets, creatinine, and urea were normal, as were results of urinalysis. Escherichia coli harboring genes for Shiga toxin were detected in stool specimens. It is concluded that extraintestinal diseases caused by Shiga toxin-producing bacteria sometimes present without any renal involvement.
