Hemolytic uremic syndrome (HUS) is one of the common causes of acute renal failure in children, but it is rarely encountered in newborns. It comprises of a triad of microangiopathic hemolytic anemia, non-immune thrombocytopenia and renal failure. Neonatal cases of HUS predominantly belong to the atypical category, resulting from abnormalities of the complement pathway or cobalamin C disorders. However, HUS cases due to infection have rarely been reported in newborns. For infection associated HUS e.g., due to Shiga toxin producing E.coli (STEC), presence of diarrhea is not a must and some cases associated with urinary tract infection (UTI) have also been seen. We present a case of a female newborn who developed HUS by acquiring the infection from her mother who had UTI associated HUS.
