He received five packed red blood cell, and one platelet transfusions, and was treated with plasma infusions during six days. Renal function was normal at discharge. HUS caused by Streptococcus pneumoniae has more morbility and mortality that classic HUS, although they usually recovery renal function. In those cases of atypical HUS, different from others, blood transfusions that contains IgM should be avoided,because they can increase antigen-antibody reaction and cellular damage. The low incidence of HUS by Streptococcus pn
