Abstract
in English, Spanish

Streptococcus pneumoniae associated hemolytic uremic syndrome (Sp-HUS) is defined as microangiopathic hemolytic anemia, thrombocytopenia and acute renal injury, in a patient with Streptococcus pneumoniae (Sp) invasive infection. A 2-year-old boy was admitted with pneumonia and empyema. Sp was isolated from blood and pleural fluid cultures. After 72 h, the patient showed paleness, asthenia, respiratory whining and oliguria. Laboratory showed anemia, low platelets, increased blood urea, creatirnina, lactate dehdrogenase, direct Coombs +, schistocytes, fibrinogen, normal coagulogram and increased D-dimer. Proteinuria and hematuria were detected in urine. Mechanical ventilatory assistance and transfusions of washed red blood cells were required. The patient recovered progressively. Sp serotype 38 was isolated in the National Reference Laboratory "Malbran". This is the first report associated to this serotype.

El síndrome urémico hemolítico asociado a Streptococcus pneumoniae (SUH-Sp) se define como anemia hemolítica microangiopática, plaquetopenia y lesión renal aguda, en un paciente con infección invasiva por Streptococcus pneumoniae (Sp). Varón de 2 años, con neumonía con derrame pleural por Sp aislado en hemocultivos y líquido pleural. A las 72 h, presentó palidez, decaimiento, quejido respiratorio y oliguria. En el análisis de laboratorio se encontró anemia, plaquetopenia, aumento de la urea, la creatinina y la lactato deshidrogenasa en sangre; coombs directa +; esquistocitos en frotis; fibrinógeno; coagulograma normal; dímero D aumentado. Orina con proteinuria y hematuria. En Terapia Intensiva requirió asistencia respiratoria mecánica y transfusión con glóbulos rojos lavados; se recuperó progresivamente. El Instituto Malbrán informó serotipo 38 de Sp. Es el primer paciente comunicado con este serotipo.
