Chronic lymphocytic leukemia-associated membranous glomerulopathy: remission with fludarabine.

摘要

In some individuals, chronic lymphocytic leukemia (CLL) may be associated with glomerular disease from membranous nephropathy with resultant nephrotic syndrome. CLL is characterized by abnormal immunoregulation with a malignant clonal proliferation of lymphocytes. The association between the abnormal clone and nephrotic syndrome is suggested in some cases by the remission of proteinuria with a reduction in abnormal lymphocyte number after treatment with antineoplastic agents. For the first time, we describe a patient with CLL and associated membranous glomerulopathy whose nephrotic syndrome remitted after treatment with fludarabine, a new purine analogue used in the treatment of refractory CLL.
