title: [Renal insufficiency in myelomatosis. Causes and treatment].
abstract: Renal failure is a frequent complication in multiple myeloma and it is present in about 50% of patients with newly-diagnosed multiple myeloma. Renal failure at the time of diagnosis has earlier been associated with a bad prognosis, but a better prognostic factor is the response to chemotherapy. In general, it is important to distinguish between 1) renal insufficiency at the time of diagnosis, 2) acute renal insufficiency and 3) chronic renal insufficiency developing during the course of the disease. The patients in the first two groups are treated with intensive therapy which is long-lasting (median four to six weeks). The improved function of the kidney is correlated to an improved survival. Patients developing chronic renal insufficiency late in the course of the disease should receive palliative therapy. The most important factors that provoke acute renal insufficiency are dehydration, hypercalcaemia and/or infection, but renal insufficiency is also provoked by the use of nephrotoxic drugs, hyperuricaemia and/or hyperviscosity. Chronic renal insufficiency is provoked by deposits of light chains, infiltration by plasma cells or deposits of amyloid. The treatment consists of elimination of the provoking factors and start of chemotherapy.
