Hemolytic uremic syndrome (HUS), a disease that destroys red blood cells, is the most common cause of sudden, short term acute kidney failure in children. By far, the commonest subgroup (>90% of childhood HUS) is induced by shiga toxin producing bacteria, usually enterohemorrhagic Escherichia coli (EHEC). These patients typically have a prodrome of diarrhea. Another important subgroup that is readily identified on clinical grounds follows invasive Streptococcus pneumonia infection. These infants tend to be younger than those with D + HUS, and the syndrome is very rare after the age of 4 years. They present with pneumonia, empyema, meningitis, and less often, isolated septicemia. Another group of patients may have mutations in complement regulators, and less often, inherited deficiency of von Willebrand protease or an inborn error of cobalamin metabolism. We report a 6-month-old child who developed hemolytic uremic syndrome following S. pneumonia meningitis.
