The authors report a case of multiple kappa myeloma comboned with chronic lymphoid leukemia. The chronic lymphoid leukemia had evolved over a 13-year period in the classical manner, without serum or urnary monoclonal immunoglobulins. The multiple myeloma with blood and urinary kappa chains appeared suddenly with a typical clinical and radiological picture accompanied by renal insufficiency. Thd diagnosis was confirmed by the demonstration of both lymphocyte and plasmocyte cell proliferation and a study of the ultrastructure which showed the sarcomatous and secretory character of the plasmocytes. A study of plasmocyte subpopulation showed the proliferation of B lymphocytes. A combination of chronic lymphoid leukemia and multiple myeloma is exceptional. The physiopathological interpretation (mono or biclonal proliferation) is discussed in the light of current nosological conceptions concerning lymphoproliferative disorders.

A study was made of the mean blood uric acid level in a group of patients with myeloma, assessed before treatment and in cases where renal insufficiency had been formally excluded. This mean uric acid level of the blood was 63.3 +/- 15 mg. per liter in a groupe of 16 men, and 59.5 +/- 16.5 mg. per liter in a group of 18 women. Comparison of these findings with those obtained in a number of control groups suggests that in myeloma without renal failure, mild hyperuricemia exists. No clear mention of this fact is found in previous publications. The moderate extent of this hyperuricemia is probably due to the fairly slow growth of the myelomatous tumor mass. It is suggested that accurate determinations of the variations of the uricemia and uraturia might yield exact data concerning the sensitivity of the myelomatous cells to the cytolytic agents used to combat them.

Serum RNase levels were measured in 34 patients with multiple myeloma and compared with 51 normal controls and 28 non-myeloma patients on chronic hemodialysis. Nineteen of the myeloma patinets with creatinine clearance (CCr) greater than 50 ml/minute had mean serum RNase levels that were statistically indistinguishable from those of the normal controls. The 15 myeloma patinets with CCr less than 50 ml/minute had mean RNase levels much higher than normal controls or myeloma patients with normal renal function. Patients without myeloma but on hemodialysis for chronic renal failure of varied etiologies had markedly elevated serum RNase levels. A strong correlation between RNase levels and renal insufficiency, as measured by CCr, has thus been demonstrated. In addition, case histories of 5 representative myeloma patients were analyzed in greater detail; they illustrated the rise and fall of RNase levels as a function of the status of their renal insufficiency, regardless of the extent of the underlying myeloma. We concluded that the serum RNase level was an indicator of renal function, and was not a biomarker either for the presence or extent of the plasma cell tumor.

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.

The authors confirm the great rarity of joint complications in patients with Kahler's disease. Among the records of 1953 cases the following complications were the only one found: 2 cases of proved articular amylosis, 2 cases of probable articular amylosis, 3 cases of possible articular amylosis, 20 cases of arthropathy that were impossible to classify, 27 cases of compression of the median nerve in the carpan canal, 6 cases of gouty arthritis, and 3 cases of septic arthritis. The data on symptoms obtained in the course of this enquiry are in conformity with the data in the literature. Articular amylosis often takes on the appearance of a polyarthritic syndrome of progressive installation and extension, involving in particular the hands and the wrists, but sometimes involving in a symmetrical bilateral manner the elbows, the shoulders, and the knees. The affected joints are swollen, stiff, and painful. Local signs of inflammation are, however, often absent. The deformations characteristic of rheumatoid arthritis do not develop. The joints do not show radiological signs for most of the time. In addition, it is not possible to detect the rheumatoid factor in the serum. The arthropathies can also assume an oligo-articular topography. Articular discharges are very frequent: they are usually of a mechanical nature. Whatever the clinical appearance, an exact diagnosis can be established only by means of anatomo-pathological examination of the synovial membrane or of certain para-articular amyloid nodules. Myelomas complicated by amyloid articular deposits are often light chain, with only little increase in the erythrocyte sedimentation rate, discrete hyperproteinaemia, moderate medullary plasmocytosis, and rare or limited radiological lesions. The carpal canal syndrome is either isolated or included within the framework of a polyarthropathy. Compression of the median nerve is due to amyloid infiltration into the synovial sheath of the tendons of the finger flexors, proof of which is not always easy. Gout is rare despite the frequency of hyperuricacidaemia caused by renal insufficiency. Septic arthritis is often caused by renal insufficiency. Septic arthritis is often caused by pneumococci to which those with a myeloma appear particularly suceptible.

From 1960 through 1972, 236 cases of amyloidosis with histologic proof were found. The amyloidosis was primary (without evidence of preceding or coexisting disease) in 132 cases (group 1) and associated with multiple myeloma in 61 (group 2). Secondary amyloidosis appeared in 19 cases (associated with rheumatoid arthritis or osteomyelitis in two-thirds of them). There were 22 patients with amyloid localized to a single organ (bladder, lung, skin, or larynx in more than half of them). Two patients had familial amyloidosis. In group 1 and group 2, the most common presenting symptoms were fatigue, weight loss, edema, dyspnea, light-headedness or syncope, and paresthesias. Symptoms of the carpal-tunnel syndrome were frequent. The liver was palpable in almost 50% of the series, but splenomegaly was an initial finding in less than 10%. Macroglossia was recorded in 26% of group 2 and in 12% of group 1. Enlargement of submandibular structures was noted in about 10% of cases; and purpura, particularly around the eyes, was a significant feature. Substantial numbers of the patients had carpal-tunnel syndrome, nephrotic syndrome, congestive heart failure, sprue, peripheral neuropathy, or orthostatic hypotension. Approximately 50% of patients had renal insufficiency at the time of diagnosis. Proteinuria was found in more than 90%. A monoclonal protein was found in the serum of 49% of group 1 and in 74% of group 2. Monoclonal proteins were found in the urine of 35% and 81%, respectively. Only 12% of patients in group 1 had no monoclonal protein when both serum and urine were analyzed, and all patients of group 2 had a monoclonal protein in the serum or urine when both were analyzed. Lambda light chains were more common than kappa. None of the patients in group 1 had more than 15% plasma cells in the marrow, whereas more than half of group 2 had more than 15% plasma cells. Roentgenograms showed no evidence of skeletal disease in 94% of group 1, but 50% of group 2 had skeletal abnormalities. Rectal biopsy was positive for amyloid in 84% of cases. Kidney, liver, and carpal-tunnel biopsies were positive in 90% or more. Follow-up of all 193 patients in groups 1 and 2 revealed that 80% of group 1 and 97% of group 2 had died. The median survival was 14.7 months in group 1 and 4 months in group 2. Cardiac failure was the most common cause of death, accounting for 30% of the fatalities. We also reclassified all cases by the method of Isobe and Osserman (105), which is based on clinical patterns: pattern I--principal involvement of tongue, heart, gastrointestinal tract, muscle, nerves, skin, and carpal ligaments; pattern II--principal involvement of liver, spleen, kidneys, and adrenals; and mixed pattern I and II. This analysis failed to reveal predictive value in the clinical pattern classification, and did not discern the survival differences between primary amyloidosis (group 1) and amyloidosis with myeloma (group 2). Consequently, for the present we prefer the classification used in this study.

We describe a 39-year-old man who developed kappa light chain nodular glomerulosclerosis with superimposed conspicuous crescent formation and extensive tubulointerstitial injury. The clinical picture was characterized by nephrotic syndrome and rapidly progressive glomerulonephritis. Incessantly progressive loss of renal function culminated in irreversible renal failure 7 weeks after initial manifestations of renal insufficiency. The patient has since been maintained on thrice weekly hemodialysis with chemotherapy for five years. At the time of pathologic diagnosis by renal biopsy, there was no evidence of multiple myeloma, and no serum M-component or Bence-Jones proteinuria was detected. An initial bone marrow aspirate revealed the presence of 0.6% atypical lymphocytes as the sole abnormality, although these were later identified as atypical plasma cells. These cells had also infiltrated the renal interstitium. Crescentic kappa light chain nodular glomerulosclerosis lacking evidence of plasma cell dyscrasia should be included in the differential diagnosis of rapidly progressive glomerulonephritis.

One hundred and twenty-two patients with multiple myeloma were classified as mature, intermediate, immature, or plasmablastic subtype according to Greipp's criteria. Contrary to Greipp's report, the survival time of plasmablastic myeloma was not significantly shorter than other subtypes, nor was the plasmablastic subtype identified as a poor prognostic factor. The survival time of mature plus intermediate myeloma was significantly longer than that of immature plus plasmablastic myeloma. Between the former and latter, significant differences were found for sex, clinical stage, thrombocytopenia, bone marrow plasmacytosis, renal insufficiency, bone destruction, and response rate to treatment. Therefore, it was suspected that the immature and plasmablastic subtypes were unfavorable prognostic factors in patients with multiple myeloma.

Patients suffering from malignant disease will probably develop some metabolic abnormality of electrolytes. Hypernatremia is defined as an elevation of serum natrium over 150 mEq/l and caused by decrease of water intake, low level of ADH secretion and impaired response of kidney to ADH. Hyponatremia below 135 mEq/l of serum natrium is caused by SI-DAH, sick cell syndrome and increased loss of natrium from the kidney. On the other hand, hyperkalemia is defined as an elevation of serum kalium over 5.0 mEq/l and caused by acute tumor cell lysis syndrome, adrenal and renal insufficiency. Hypokalemia is caused by kalium loss from kidney and hypersecretion of mineral corticoid. Hypercalcemia is found in the high frequency among patients with malignant disease. Hypercalcemia is defined as an elevation of serum calcium over 11.0 mg/dl, although the most important aspect is the level of ionized calcium. The excess calcium causes defective urinary concentration with polydipsia, nausea and vomiting leading to volume depletion. At serum calcium levels about 13.8 mg/dl, there may be rapid deterioration or renal function, dehydration, coma and cardiac arrhythmias. Hypercalcemia is rarely the first manifestation of cancer. There are three principle pathogenic causes of malignant hypercalcemia, 1) hypercalcemia is a feature of several hematological cancers, including Burkitt's lymphoma, T cell leukemia, but most commonly with myeloma. The hypercalcemia in these myeloma patients is due to the secretion of an osteoclast activator, a lymphokine by the myeloma cells. 2) all patients with bony metastases have biochemical evidence of increased bone resorption. However, not all patients with bony metastases develop hypercalcemia. Probably the hypercalcemia is due partially to increased renal tubular reabsorption of calcium, mediated by a humoral factor, with activity similar to that of parathormone. 3) hypercalcemia in the patients without bony metastases is due to increased bone resorption caused by the ectopic secretion by the tumor. Mildly symptomatic patients will benefit from modest salt loading. They are dehydrated and replacement of the extracellular fluid is the first line of treatment. This may require 4-10 l normal saline/24 h. In addition, frusemide will increase calcium excretion. Calcitonin may be given subcutaneously or intravenously to refuse the mobilisation of calcium from bone. Glucocorticoids are unhelpful, but will prolong the effect of calcitonin. A diphosphonate is also useful.

We compared the presentation features of three series of patients with multiple myeloma diagnosed between 1960 and 1971 (Kyle R, Mayo Clin Proc, 1975, 50, 29, n = 869), 1972 and 1986 (Clinica Medica, University of Pavia, n = 345) and 1987 and 1990 (Cooperative Group for Study and Treatment of Multiple Myeloma, n = 341). In the most recently diagnosed patients, the percentage of those who had symptoms related to multiple myeloma (i.e. any of bone pain, systemic symptoms, disturbances related to hypercalcemia, neurological involvement and hyperviscosity) was reduced (90 vs. 86 vs. 66%) (P less than 0.001), while the percentage of asymptomatic patients diagnosed by chance was increased (not reported, and 14 vs. 34%). In the most recent series, a lower percentage of spontaneous bone pain (68 vs. 60 vs. 37%, P less than 0.001) paralleled a lower incidence of advanced bone disease (osteolyses and pathological fractures, 60 vs. 64 vs. 34%), and renal failure (serum creatinine greater than 1.2 mg/dl) was also less common (56 vs. 44 vs. 33%, P less than 0.01), at least partially due to a decreased incidence of both hypercalcemia (30 vs. 20 vs. 18%, P less than 0.001) and of hyperuricemia (serum uric acid greater than 7 mg/dl, 47 vs. 32 vs. 26%, P less than 0.01). Systemic symptoms (weakness, infections, fever or weight loss) were reported more seldom by recently diagnosed patients, due to a decreased frequency of anaemia (haemoglobin less than 12 g/dl), leukopenia and thrombocytopenia, as well as of the systemic effects of bone pain and of renal insufficiency. These data indicate that multiple myeloma is diagnosed earlier now than in the past, and this must be taken into account when comparing survival data in treated series.
