Abstract
A 68-year-old gentleman with a long history of type 2 diabetes mellitus and recurrent multidrug resistant urinary tract infection and a recent history of a carbuncle, presented with a one week history of fever and dysuria. Laboratory results included erythrocyte rouleaux formation, ESR 121 mm/h, creatinine 217umol/l, total protein 83 g/l, albumin 32g/l, and Bence-Jones protein in the urine. Skull X-ray showed multiple lytic lesions. Serum protein electrophoresis showed a monoclonal band of33g/ I of IgA kappa, IgG 665 mg/dl, and IgM 26.9 mg/dl. Bone marrow aspirate showed an infiltration of plasma cells. Renal biopsy showed a mild cast nephropathy with mild diabetic glomerular disease. The patient was assessed as stage IIIB multiple myeloma IgA kappa type and was started on chemotherapy MP protocol (oral Melphalan 5 mg/sq m body surface area plus oral prednisolone 60mg/sq m body surface area for four days every four weeks) after which he became stable.
