ABSTRACT
La glomerulonefritis aguda desencadenada por Streptococcus pneumoniae es una patología de baja prevalencia. Existen diversos reportes que comunican distintas cepas nefritogénicas; sin embargo, la 6C ha sido escasamente señalada como tal.Se presenta el caso de un paciente de 4 años, quien ingresó a Terapia Intensiva con pleuroneumonía por Streptococcus pneumoniae serotipo 6C y desarrolló, de modo concomitante, edemas, hipertensión arterial, hematuria, proteinuria, disminución del filtrado glomerular y del nivel de complemento C3. Se diagnosticó glomerulonefritis aguda. Su evolución fue satisfactoria en un breve plazo. Esta patología, por lo general, es de curso transitorio y benigno; sin embargo, en ocasiones, puede complicar la evolución de un paciente críticamente enfermo, por lo cual se hace necesario tenerla entre los diagnósticos diferenciales para considerar.
Acute glomerulonephritis caused by Streptococcuspneumoniaeis a low prevalence pathology. There are several reports communicating different nephritogenic serotypes, however, 6C has been scarcely indicated as such. It is presented the case of a 4-year-old patient who entered Intensive Therapy Unit with pleuropneumonia due to Streptococcuspneumoniae serotype 6C and concomitantly developed edemas, arterial hypertension, hematuria, proteinuria, decreased glomerular filtration rate and C3 complement level. Acute glomerulonephritis was diagnosed. His evolution was satisfactory in a short time. This pathology is usually of a transitory and benign course; however, sometimes it can potentially complicate the evolution of a critically ill patient, so it is necessary to have it among the differential diagnoses to consider.

Hemolytic-uremic syndrome (HUS) is an uncommon complication of pneumococcal infection. Highly suggesting findings in a patient with Streptococcus pneumoniae infection are: microangyopatic hemolytic anemia, thrombocytopenia and acute renal failure. We report a 41 years old woman, admitted to the hospital due to a severe pneumonia, that required the surgical drainage of an empyema. On admission, a drop in packed red cell volume from 41 to 25 percent, the presence of schistocytes in the blood smear, an elevation of LDH to 1,700 IU/L, a fall in haptoglobin to 5.8 mg/dL and a thrombocytopenia of 72,000 per mm3 were detected. These alterations coincided with an oliguric acute renal failure. She was treated with hemodialysis and the hemolytic syndrome was managed with plasmapheresis. She was discharged 35 days after admission and in the follow up, after 2.5 months, her serum creatinine is 1.2 mg/dL and her packed red cell volume is 41 percent
