ABSTRACT

Os autores relatam um caso infreqüente de púrpura trombocitopênica trombótica associada à infecção urinária por Escherichia coli e apresentam uma revisão bibliográfica sobre o assunto. A púrpura trombocitopênica trombótica é uma complicação incomum da infecção urinária por Escherichia coli. Caracteriza-se por anemia hemolítica microangiopática, trombocitopenia, sintomas neurológicos, insuficiência renal e febre. Entretanto, somente 40% dos casos apresentam todos esses sinais/sintomas. Sua evolução pode ser fatal se não for diagnosticada e tratada precocemente. No caso descrito, somente o tratamento agressivo do quadro séptico, com antibióticos, medidas de suporte e remoção do foco infeccioso (nefrectomia), e o manejo da púrpura trombocitopênica, com imunoglobulina, corticoterapia e plasmaférese associada à reposição de plasma fresco possibilitaram a recuperação da paciente (AU)


The authors report a rare case of a patient with thrombotic thrombocytopenic purpura associated with Escherichia coli urinary tract infection and present a review about this subject. Thrombotic thrombocytopenic purpura is an uncommon complication of Escherichia coli urinary tract infection. It is characterized by microangiopathic hemolytic anemia, thrombocytopenia, neurologic abnormalities, renal failure and fever. However, only 40% of cases do present all of these signs and symptoms. The disease can be fatal if not diagnosed and treated early. In our report, only the aggressive management of the urinary sepsis, with general measures, antibiotics and the removal of the septic focus (with nephrectomy), and the treatment of the thrombotic thrombocytopenic purpura with immunoglobulins, corticosteroids and plasmapheresis with administration of fresh plasma have allowed the patient to recover (AU)
