title: Successful intravenous immunoglobulin therapy for severe and persistent astrovirus gastroenteritis after fludarabine treatment in a patient with Waldenström's macroglobulinemia.
abstract: A 78-year-old male with Waldenström's macroglobulinemia was after 23 years of conservative treatment given fludarabine phosphate in 1993 because of disease progression. Three weeks after the third fludarabine course he presented with a 5-day-history of watery diarrhoea, nausea and vomiting. Stool cultures were negative but a semiquantitative electron microscopy method demonstrated massive amounts of astrovirus (> 10(14) particles/ml). Symptomatic treatment was given but since his condition deteriorated, high-dose intravenous immunoglobulin (IvIg) treatment, 0.4 g/kg for four days was initiated. Within twenty-four hours all symptoms disappeared and the patient was discharged after a few days. A stool sample collected after two weeks demonstrated 10(7) particles/ml and after four weeks no astrovirus could be detected. The association between fludarabine and this opportunistic infection and the potential role of high dose IvIg treatment are discussed.
