Title: Long-term outcome according to renal histological lesions in 118 patients with monoclonal gammopathies.

Abstract: BACKGROUND: The prognosis of monoclonal gammopathies with multiple myeloma and renal involvement is poor, and the indication for renal replacement therapy is controversial. Few studies address the value of renal histology for determining prognosis according to initial pathology findings. METHODS: We studied the course of 118 patients with multiple myeloma according to renal biopsy lesions. The monoclonal component was identified and quantified in serum and urine. Tumor cell mass was classified as stage 1, 2 or 3, according to Durie and Salmon. End-points were death, or survival on dialysis, or serum creatinine level at last examination. RESULTS: Renal biopsy showed myeloma kidney in 48 cases (41%), AL-amyloidosis in 35 (30%), light chain deposit disease in 22 (19%), chronic tubulointerstitial nephritis in 12 (10%) and cryoglobulinaemic kidney with multiple myeloma in 1. Maintenance haemodialysis was required in 46 patients (39%), earlier (P<0.0001) in myeloma kidney (mean: 3 months after diagnosis) than in AL-amyloidosis (mean: 15 months) and light chain deposit disease (mean: 18 months). Median survival was 12 months in myeloma kidney, 24 months in AL-amyloidosis and 48 months in light chain deposit disease. Dialysis increased survival in light chain deposit disease, in contrast with myeloma kidney and AL-amyloidosis patients whose survival was shorter when dialysed. The main cause of death during first year of dialysis was cardiac involvement in AL-amyloidosis, and sepsis or cardiac insufficiency in myeloma kidney. There was a trend to increased survival with multidrug chemotherapy which seemed to slow progression to end-stage renal failure. At last follow-up (median: 12 months, range 1-297), 65 (55%) patients had died. By multivariate analysis, independent predictors of survival were: age < 70, serum creatinine < or = 300 micromol/l, and serum calcium < or = 2.5 mmol/l. CONCLUSIONS: Initial renal biopsy helps predict prognosis in patients with multiple myeloma and renal involvement. Maintenance haemodialysis is a reasonable indication in light chain deposit disease and AL-amyloidosis, especially in patients aged < 70. Multidrug therapy tends to prolong survival and slow progression to end-stage renal disease. CAS Registry/EC Number 0 (Antineoplastic Combined Chemotherapy Protocols).

Title: Presentation and survival of patients with severe renal failure and myeloma.

Source: Qjm. 90(12):773-80, 1997 Dec.

Abstract: We reviewed the clinical features and outcome of 56 patients with myeloma and severe renal failure managed in a single institution over a 15-year period. Renal failure was recognized within 2 months of the diagnosis of myeloma in 75% of patients, and was the initial presentation of myeloma in 50%. Patients were staged by the Durie and Salmon classification. Light-chain and IgD myeloma accounted for 46% of cases, and Bence-Jones proteinuria was identified in > 90%. In 43%, a potential precipitant of renal failure was identified, usually hypercalcaemia or a non-steroidal anti-inflammatory agent. A preserved corrected calcium at presentation was characteristic (2.40 +/- 0.15 mmol/l, n = 42), even after excluding those with hypercalcaemia requiring specific intervention (n = 14, 2.76 +/- 0.51; p < 0.01): this finding in patients with unexplained acute renal failure should alert clinicians to the possibility of myeloma. Forty-seven patients (84%) required dialysis. Only seven (15%) ever regained renal function. Median survival (all patients) was 8 months. One-third died within 3 months of referral and one-third survived > 1 year. Hypoalbuminaemia and reduced platelet count at presentation were associated with reduced survival, but hypercalcaemia, infection, dialysis, (urgent or long-term), and dialysis modality were not. Chemotherapy was associated with increased survival, but progression of myeloma and infection were the two most frequent causes of death. Severe renal failure was associated with advanced myeloma stage and light-chain/IgD paraproteinaemia. Survival was related to severity of myeloma and not requirement for dialysis per se.

Title: Patients with multiple myeloma requiring long-term dialysis: presenting features, response to therapy, and outcome in a series of 20 cases.

Source: British Journal of Haematology. 91(4):854-9, 1995 Dec.

Abstract: From January 1982 to December 1993, 30 patients with multiple myeloma (MM) required haemodialysis (HD) at our institution. The subgroup of 20 patients who survived more than 2 months on HD is the subject of this study. Four patients were already on HD, due to previous nephropathy, when MM was diagnosed. 13 patients presented with acute renal failure and were on dialysis from the time of diagnosis. The remaining three cases developed renal failure later in the course of the disease. The objective response rate was 40% (8/20). Only two patients could discontinue HD (one had a late partial recovery and one received a kidney graft). Mean hospitalization per year was 19.3 d. The subgroup of patients who survived < 1 year spent a mean of 38.3 d in hospital. Whereas in the subgroup with a survival > 1 year mean hospitalization days was 9.6 (P < 0.001). The median survival was 20 months and six patients survived for > 3 years. In summary, patients with MM and severe renal failure who survive the first 2 months on dialysis have an objective response rate to chemotherapy of 40% and a median survival of almost 2 years, with 30% long-term survivors.

Title: Management of renal complications in patients with advanced multiple myeloma.

Source: Leukemia & Lymphoma. 38(5-6):513-9, 2000 Aug.

Abstract: Although the kidney is frequently involved in malignant monoclonal gammopathy, the clinical outcome of the patients varies considerably. We retrospectively assessed the clinical course in seventeen patients with acute and chronic renal failure suffering from multiple myeloma, and analyzed their case history focusing on the therapeutic management, the possible clinical improvement as well as the patients' outcome. Treatment included chemotherapy (n = 17), forced diuresis (n = 3), hemodialysis (n = 11, 7 chronic, 4 intermittent) and plasmapheresis (n = 3). Renal function improved in five patients, and was stabilized compensated in four. Seven patients developed end-stage renal disease, one refused further treatment and was lost for follow up. In addition to renal failure, the most frequent complications included local bone destruction (all), anemia (n = 12), low platelet count (n = 11), and bacterial infections (n = 9). One year survival rate after admission to the nephrology department was 76 percent. Chemotherapy in combination with renal replacement therapy may improve the clinical course even in MM patients with serum creatinine levels above 3.0 mg/dL or end-stage renal disease.
