Evans syndrome: a report on 12 patients.
From 1981 to 1989, 12 patients of the University Hospital, Kuala Lumpur, were diagnosed to have Evans syndrome based on direct antiglobulin test (DAT) positive haemolytic anaemia and immune thrombocytopenia occurring either simultaneously (7 patients) or consecutively (5 patients). Their mean age at presentation was 24.8 years with a marked female preponderance. All 12 patients were given high dose steroid after diagnosis. Subsequently, other modalities including intravenous immunoglobulin (1 patient) and high dose methylprednisolone (1 patient) were given. Three patients died of intracranial haemorrhage during the first admission while 1 patient died of pulmonary embolism six months after diagnosis. Three patients had splenectomy because of thrombocytopenia. Six patients tested positive for antinuclear factor and antibodies to double stranded DNA and four of them died. Positive serology appeared to be associated with a poorer prognosis. Follow up observations indicate that patients who survive the acute attacks fare reasonably well.
