Six cases of leukemic myelomatosis (plasma cell leukemia), are reported. A spectrum of leukemic plasmacellular proliferation was observed in this group: in two cases the plasmacytic leukemia was a terminal event of multiple myeloma, in one of a chronic lymphocytic leukemia, and in the remaining three cases the peripheral blood plasmacytosis was a presenting manifestation of an acute immunocytic dyscrasia. The clinical features, frequencies of extraosseous plasmacytic infiltrations, hypercalcemia and Bence Jones proteinuria, and cytomorphologic difficulties in differentiating plasmacytic from chronic lymphocytic leukemia are discussed.

Patients with asymptomatic or smoldering multiple myeloma should not be treated but should be observed closely for progression. For symptomatic myeloma, chemotherapy is indicated. Melphalan, the agent of choice, should be given with prednisone for 1 week of every 6 weeks, If melphalan brings no response, or response and then relapse, cyclophosphamide (Cytoxan) should be give intravenously every 4 weeks or orally every day. BCNU, CCNU, and doxorubicin (Adriamycin) have also shown activity in myeloma. Hypercalcemia occurs in one-third of patients and should be countered with hydration, corticosteroids, Neutra-Phos, or mithramycin. Long-term hemodialysis has achieved some success. The combination of sodium flouride and calcium carbonate produces new bone formation; it seems a useful adjunct in treatment for myelomatous bone disease. Radiation should be utilized only for severe, localized pain or for solitary lesions. Survival with multiple myeloma varies, mean durations being 2 to 3 years. Multivariate analysis indicates that serum creatinine and calcium levels are the most significant indicators regarding 2-year survival. We have found monoclonal proteinuria not significantly more frequent with renal insufficiency than with normal renal function, renal insufficiency not significantly more frequent with lambda than with kappa chains, and survival not significantly greater with IgG myeloma than with IgA.

Ninety-seven patients with light chain disease (LCD) were studied. The median survival from diagnosis was 30 mo for 52 patients with kappa-LCD and 10 mo for 45 patients with lambda-LCD (p less than 0.0007). A lower proportion of kappa-LCD patients (15.7%) than lambda-LCD patients (42.2%) died within the first 6 mo after diagnosis. The survival of the remaining patients with kappa-LCD was still much longer than of those with lambda-LCD (p = 0.022). The shorter survival of lambda-LCD patients could not be ascribed to an increased incidence of recognized manifestations indicating a poor prognosis (e.g., anemia, hypercalcemia, azotemia, low albumin, the extent of osteolytic lesions, or proteinuria), the incidence of amyloidosis, the clinical stage of the disease at diagnosis, or the response to treatment, and remains unexplained. A comparison of the clinical manifestations of LCD with those of other myelomas revealed some differences. LCD patients were slightly younger than IgA and IgG patients but older than IgD patients. A 1:1 ratio of males to females was similar to the ratios in IgA and IgG myeloma, but differed from the 3:1 ratio reported for IgD myeloma. Plasma-cell leukemia developed in 7/97 LCD patients, an incidence that was higher than has been reported in other myelomas. The initial BUN was more than or equal to 30 mg/100 ml in 54 of 95 LCD patients, an incidence that was higher than has been reported for IgA and IgG myeloma, but lower than the incidence in IgD myeloma. The incidence of amyloidosis in LCD (23 of 97 patients) was similar to that reported for IgA and IgG myeloma, but less than the incidence in IgD myeloma.

This patient had an acute onset of myeloma, with hypercalcemia, a high M-component in the plasma, Bence Jones proteinuria, and 37% plasma cells in the bone marrow sample. After melphalan treatment (210 mg totally) he seems to have a complete cure, with total disappearance of the M-component, Bence Jones proteinuria, myeloma cells, hypercalcemia and elevated ESR for almost three years.

The clinical, haematological and biochemical correlations of 224 consecutive unselected examples of monoclonal gammopathy have been studied. The paraprotein frequency detedted was IgG 62 percent, IgA 15.2 percent, IgM 10.3 percent, Bence Jones protein 8.9 percent and in 3.6 percent the paraproteins were not identified. In half the monoclonal gammopathy was associated with an immunocytoma (myeloma in 82 and lymphoma in 30). In three cases the associated clinical disease was amyloidosis. In 36 cases (16.1 percent) the associated clincial disease was a nonlymphoproliferative malignant tumour. Monoclonal gammopathy may be a significant marker of malignancy in such cases. In 73 cases (32.6 percent) the associated clinical conditions were unrelated to the gammopathy although only 55 of these cases were sufficiently investigated to warrant classification as examples of benign monoclonal gammopathy. There was a strong correlation between Bence Jones proteinuria and malignancy. Sixty-five patients demonstrated Bence Jones proteinuria and in 59 of these a malignancy was detected. The association was strong between hypercalcaemia and malignancy as this was present in all 27 of the cases who had hypercalcaemia. The relationship between Bence Jones proteinuria and hypercalcaemia was also strong and Bence Jones proteinuria was detected in 73 percent of the hypercalcaemic patients as opposed to 36.7 percent in the whole series. Hypercalcaemia and Bence Jones proteinuria, when found in a patient with monoclonal gammopathy have a grave clinical connotation.

A review of 869 cases of multiple myeloma seen at the Mayo Clinic from 1960 through 1971 revealed that 98% of patients were 40 years of age or older and that 61% of them were males. Inital findings were bone pain in 68% of patients, anemia in 62%, renal insufficiency in 55%, hypercalcemia in 30%, a palpable liver in 21%, and a palpable spleen in 5%. Proteinuria was noted in 88% and Bence Jones proteinuria was identified in 49%. Skeletal roentgenographic abnormalities were seen in 79%. Serum protein electrophoresis showed a spike in 76%, hypogammaglobulinemia in 9%, and minor or no abnormalities in 15%, and a globulin spike was seen 75% of the urinary electrophoretic patterns. Immunoelectrophoresis of the serum revealed a monoclonal heavy chain in 83% and a monoclonal light chain in the serum, in 8% (Bence Jones proteinemia). Three patients had no monoclonal protein in the serum or the urine ("nonsecretory"). Amyloidosis was found in 7% of the patients. Follow-up information was obtained in 99.7% ; 82% of the 869 patients have died. Infection and renal insufficiency were the most common specific causes of death. The median survival was 20 months; 66% of the patients were alive at 1 year and 18% at 5 years.

1. The clinical manifestations, laboratory data and renal histologic features of acute renal failure occurring in 14 patients with multiple myeloma are reviewed and contrasted with the data from 29 previously reported cases. 2. Whereas other reports have stressed the role of intravenous pyelography and dehydration in the development of acute renal failure in multiple myeloma, the most common etiologic factor in our experience was hypercalcemia (7 patients). Other factors included potentially nephrotoxic antibiotics (3 patients) and volume depletion (2 patients). Intravenous pyelography could be clearly implicated in ony one patient. 3. The unusually high incidence of Bence Jones proteinuria in these patients is consistent with the possibility that Bence Jones protein excretion is associated with an increased susceptibility to renal injury. This could be due to an adverse effect of Bence Jones proteins on the renal tubules or their tendency to precipitate in tubular lumina during periods of reduced tubular flow. 4. The prognosis of patients with multiple myeloma who develop acute renal failure is poor; only 5 of our 14 patients survived the early period of acutely impaired renal function, and 4 of these subsequently died within 2 months. Preventive measures particularly the prompt correction of hypercalcemia and volume depletion, are the most important aspects of patient management.

This report deals with an unusual case of primary macroglobulinemia with hypercalcemia, chronic renal failure and systemic amyloidosis. In May 1990, a 63-year-old male was transferred to our hospital because of hypercalcemia (13.5 mg/dl) and renal failure. Clinical examinations showed anemia, macroglossia, lymph node swellings and hepatomegaly. Laboratory findings included Bence-Jones (kappa type) proteinuria (0.8 g/day), a monoclonal gammopathy of the IgM-kappa type (2.8 g/dl), a proliferation of lymphoid cells in the peripheral blood (5%) and the bone marrow (59.6%), and lymphomatous involvement of an inguinal lymph node. Serum creatinine concentration was 8.5 mg/dl. The serum levels of parathormone and vitamin D3 metabolites were normal. The roentgenogram of bones showed a compression fracture of the lumbar spine and systemic osteoporosis. The treatment included eel calcitonin, prednisolone and the CHOP regimen, followed by hemodialysis and plasmapheresis. The serum level of IgM increased to 4.6 g/dl. The patient died three months later and postmortem examination demonstrated marked systemic amyloidosis.

Contrast media administered intravenously are still thought by many to be a major cause of acute renal failure (ARF) in myeloma patients. Recently, several authors found that the predominant risk factors of ARF in myeloma patients are hypercalcemia, dehydration, infection, and Bence Jones proteinuria rather than contrast media. In a review of seven retrospective studies of myeloma patients receiving contrast media, 476 patients were noted to have undergone 568 contrast media studies, with an ARF prevalence of 0.6%-1.25%. One large series showed the incidence of ARF after administration of contrast media to be 0.15% in the general population. Although the administration of contrast media to myeloma patients is not totally risk free, it may be performed if the clinical need arises and the patient is well hydrated.

Mercuric chloride induces in BN rats a self-limiting systemic autoimmune disease characterized by proliferation of autoreactive CD4+ T lymphocytes, polyclonal activation of B lymphocytes, and the development of an anti-glomerular basement membrane (GBM) nephritis with concomitant nephrotic range proteinuria. We have used this model of autoimmune disease to test the immunosuppressive ability of a novel vitamin D3 analogue KH1060. This compound prevents autoimmune manifestations including proteinuria, serum IgE, and serum anti-laminin antibodies in a dose-dependent manner, as does cyclosporin A (CyA). When dosages of KH1060 capable of partial reduction of proteinuria without causing significant hypercalcaemia are combined with small dosages of CyA also capable of partial prevention of proteinuria, an additive effect is seen, leading to complete prevention of proteinuria and substantial reductions in serum IgE and anti-laminin levels. Possible mechanisms of action are discussed and it is suggested that KH1060 could prove useful as an immunosuppressive agent in the treatment of autoimmune diseases.
