*Serum creatinine significantly higher in multiple myeloma patients compared with the dialysis population as a whole, P < 0.02. **One patient with known chronic lymphocytic leukaemia, in remission, presented with acute renal failure and biopsy proven cast nephropathy. Investigation identified an intact IgM band on immunofixation electrophoresis with an associated λ FLC, bone marrow examination provided a haematological diagnosis of IgM myeloma.
