RESUMEN
Las microangiopatías trombóticas (MAT), que incluyen la púrpura trombótica trombocitopénica (PTT) y al síndrome urémico-hemolítico (SUH), se diagnostican habitualmente por la presencia de anemia hemolítica no inmune y trombocitopenia, lo que lleva a tratarlas con plasmaféresis. Se reporta el caso de una paciente de 51 años que ingresó con insuficiencia renal aguda-subaguda de etiología desconocida cuya biopsia renal mostró microangiopatía trombótica pero sin trombocitopenia ni anemia hemolítica. Por lo tanto dicha patología no siempre seria diagnosticada con los criterios actuales, debiendo utilizarse otros marcadores como ADAMTS-13.
ABSTRACT
The disease category of thrornbotic microangiopathy (TM) encompass diffcrent entities such as thrombocvtopenic thrombotic purpura (TTP) and uremic hemolytic syndrorne (UHS) , both strongly related and whose diagnosis relies on the presence of non immune hemolytic anemia and trombocytopenia, findings that should urge the caring physician to start plasmapheresis promptly. We report the case of a 51 year old woman admitted with acute-subacute renal failure of unknown etiology whose renal biopsy finding was thrombotic microangiopathy, in absence of thrombocytopenia and haemolytic anemia. This inusual case and according to published literature can not be diagnosed on standard accepted criteria and others markers like ADAMTS-13 should be considered.
