[A case of chronic myelogenous leukemia complicated with nephrotic syndrome]

An 81-year-old woman was admitted, complained general malaise, and edema on face and lower extremities. In the peripheral blood, leucocytosis (17,220/mm3), microcytic hypochromic anemia (RBC 348 x 10(4)/mm3, Hb 9.6 g/dl, Ht 29.2%), and thrombocytosis (130 x 10(4)/mm3) were present, and many myeloid cells containing of myeloblasts, promyelocytes and so on were observed. Bone marrow aspiration revealed increment of the myeloid series without hiatus leukemia . The Neutrophil Alkaline Phosphatase score and rate was low, and on bone marrow scintigram using indium chloride, liver and extremities were shown. On admission, proteinuria (21.5 g/dl) and hypoalbuminemia (2.5 g/day) were pointed out, and the renal biopsy specimen showed membraneous proliferative glomerulonephritis (MPGN), so we diagnosed this case that chronic myelogenous leukemia (CML) complicated with nephrotic syndrome. At first, she was treated with prednisolone, but proteinuria was not entirely improved, then busulfan was given, myeloid cells in peripheral blood were disappeared and proteinuria was gradually decreased. From this coarse, the causality between CML and nephrotic syndrome was verified.
