A 73-year-old male was admitted to our hospital in October 1987 because of severe anemia, anorexia, and loss of weight. The hemoglobin level was 5.7 g/dl, the white blood cell count 2,500/microliters with 5% myeloblasts positive for peroxidase, and the platelet count 8.6 x 10(4)/microliters. The LDH was 656 mU/ml, the total protein in the serum 7.4 g/dl, IgG 419 mg/dl, IgA 104 mg/dl, IgM 10 mg/dl, and urine Bence Jones (BJ) protein 8.8 g/day. The X-ray survey of the bones showed multiple osteolytic lesions. A bone marrow aspirate was hypercellular with 91.4% plasma cells, and was cultured a whole day for chromosome study. It revealed an abnormal karyotype of 46, XY, -15, t(6; 14) (p21.1; q32.3), +der(15)t(1; 15) (q23; q24). Immunoelectrophoresis demonstrated lambda type BJ protein. He was treated with melphalan and prednisolone. Proteinuria and marrow plasma cells decreased in amount. In December a white cell count was 6,030/microliters with 80% myeloblasts. A bone marrow aspirate revealed an increase of 82.6% myeloblasts or promyelocytes. The patient was refractory to chemotherapy and died of sepsis in April 1988. An unrelated abnormal karyotype; 48, XY, +8, +13 appeared concomitant with an increase of the leukemic cells, but no cells showed the t(6; 14). We cytogenetically discussed the simultaneous presence of multiple myeloma with acute myelogenous leukemia.

In a 59-year-old man with multiple myeloma (kappa-light chain paraproteinaemia) in stage IIIB, bone marrow infiltration with atypical plasma cells was reduced by five cytostatic treatment courses with vincristine, melphalan, cyclophosphamide and prednisone (VMCP protocol), but anaemia requiring blood transfusion persisted (haemoglobin concentration 5.3 g/dl). Even administration of interferon alpha-2b (5 million units s.c. every other day) failed to alter this. Only a combination of interferon and erythropoietin (150 U/kg i.v. every other day) achieved lasting regression of the anaemia (haemoglobin concentration up to 14 g/dl). In four other anaemic patients with multiple myeloma, stage III, treated according to the VMCP protocol but without additional interferon, erythropoietin did not improve erythropoiesis.

A monoclonal anti-equine infectious anemia virus (anti-EIAV) antibody (1B15) has been generated by fusion of X63 Ag 8.653 myeloma cells and spleen cells from mice hypersensitized with viral antigen p29. Ouchterlony double-diffusion analysis indicated that antibody 1B15 is of the IgG class. The specificity of the immune reaction for p29 was confirmed by cross-over immunoelectrophoresis and disc-gel electrophoresis. MAb 1B15 was used to devise a solid-phase 'capture' RIA for EIAV-p29 antigen. The antigen, bound by 1B15 adsorbed onto wells of flexible microtitre plates, was detected using a rabbit anti-p29 serum followed by a 125I-labelled tracer. The assay was applied to detected using a of virus in horse serum and infected cell culture fluids.

Plasma UBBC-B12 and transcobalamins were measured in 112 patients suffering from different haematological disorders. The data showed different patterns of changes in plasma transcobalamin profile in different haematological disorders. Plasma UBBC-B12 and transcobalamins were significantly higher than normal in untreated chronic myeloid leukaemia, acute promyelocytic leukaemia, nutritional megaloblastic anaemia and in refractory anaemias with hypercellular marrow. Normal levels of these proteins were noted in chronic lymphatic leukaemias, in primary and secondary hypereosinophilic states and in multiple myeloma. Subnormal levels of these proteins were observed in hypoplastic anaemia and acute lymphoblastic leukaemia. Chronic myeloid leukaemia patients during blast crisis and acute myeloid leukaemia patients except those suffering from acute promyelocytic leukaemia showed varying pattern of plasma transcobalamins depending on type of blast crisis or FAB subtype of AML. The significance of these changes in plasma transcobalamins have been discussed along with the experience of other workers in this field.

A 63-year-old man was admitted to our hospital with tremor and somnolence, followed soon by coma. Anemia and retinal bleeding were observed. The blood smear exhibited rouleaux formation and leukoerythroblastosis. A bone marrow aspiration resulted in dry tap. The biopsy specimens revealed remarkable infiltration of myeloma cells with fibrosis. The M-component of IgG-lambda type and hyper-ammonemia were detected in the serum. Liver and renal functions, however, were within normal range. His consciousness recovered after plasmapheresis. Two courses of VMCP (vincristine, melphalan, carboquone and prednisolone) did not affect the paraproteinemia. Five courses of VAD (vincristine, adriamycin and dexamethasone) could lower the level of IgG. He died of pneumonia. The plasma of some patients with multiple myeloma may contain unidentified factors which increase the plasma ammonia.

A 73-year-old man was admitted into the hospital because of lumbago in October, 1986. Laboratory examination on admission showed anemia, an IgA-kappa Bence Jones proteinemia. The bone marrow picture disclosed a marked involvement by the neoplastic cells, followed by leukemic conversion 2 weeks later. The leukemic cells displayed a lymphoblastoid appearance on light microscopy, but rather compatible with plasma cells on electron microscopy, showing some strands of rough endoplasmic reticulum and a prominent Golgi apparatus in the cytoplasm. The cells expressed a wide spectrum of surface markers, including those of plasma cell (PCA-1, OKT10), B cell (B1, sIg) and CALLA. Reverse hemolytic plaque assay disclosed the immunoglobulin production of monoclonal kappa chain, but a heavy chain production was recognized only in a small proportion of the cells. Under the diagnosis of multiple myeloma, he was treated with vincristine, cyclophosphamide, and prednisolone. But he died of renal failure complicating hypercalcemia after only three months of the admission in accordance with previous reports that CALLA-positive myeloma was associated with poor prognosis. This case may also represent the clinical, morphological and phenotypic diversity in multiple myeloma.

Pyoderma gangrenosum (PG) is a rare condition remarkable for its association with particular diseases, notably haemopathies and gastrointestinal diseases. As regards haemopathies, the associations most frequently encountered are with myeloid malignancies and monoclonal dysglobulinaemia. The association of PG with mainly inflammatory digestive tract diseases is also classical. The lack of publications concerning gastric atrophy and the dual haematological and gastric pathology which characterizes our case have prompted us to report it. A 60-year-old woman without significant history was admitted for PG on both knees, following vesiculo-bullous lesions. Laboratory examinations detected a normochromic anaemia tending to be macrocytic, a marked inflammatory syndrome and a monoclonal lambda light chain IgA peak at protein immunoelectrophoresis. Bone marrow biopsy, skeletal radiography and a search for Bence-Jones proteinuria were normal or negative. Colonoscopy showed no abnormality, but fibroscopy of the upper digestive tract revealed a severe gastric atrophy en plaques. Serum vitamin B12 level was moderately low, but there was no other sign of pernicious anaemia. After one month treatment with systemic corticosteroids, healing was obtained under replacement vitamin therapy. PG recurred a few months later; serum vitamin B12 level was normal, and the lesions healed after systemic corticosteroid treatment. In non-myelomatous dysglobulinaemia IgA is frequently found and there is no light chain predominance. PG often precedes dysglobulinaemia. Evolution towards a true myeloma seems to be exceptional. In a recent publication, 17 cases of association between PG and myeloma were mentioned, the IgA type being most common. Protein electrophoresis is indispensable in patients with PG. Five cases of congenital hypogammaglobulinaemia have been recorded, including three with IgA deficiency.(ABSTRACT TRUNCATED AT 250 WORDS)

Patients with monoclonal gammopathy of undetermined significance (MGUS) have a monoclonal protein but no evidence of multiple myeloma, macroglobulinemia, amyloidosis, or related disorders. In a long-term follow-up (median, 19 years) of 241 patients with MGUS, 53 (22%) developed multiple myeloma (36 patients), macroglobulinemia (7 patients), primary systemic amyloidosis (7 patients), or malignant lymphoproliferative disease (3 patients). Fifty-seven patients (24%) remained stable and were alive, while 124 patients (51%) died of causes unrelated to the monoclonal gammopathy. Multiple myeloma was diagnosed in the 36 patients 23 to 251 months (median, 9.6 years) after recognition of the M-protein. Smoldering multiple myeloma (SMM) is characterized by a serum M-protein level greater than 30 g/l and greater than 10% plasma cells in the bone marrow but no anemia, renal insufficiency, or lytic lesions. Differentiation of MGUS and SMM from multiple myeloma and macroglobulinemia is difficult at the time of diagnosis of the M-protein, and the patients must be followed up indefinitely.

Between January 1, 1972 and December 31, 1985, 28 cases of IgD myeloma were diagnosed in the Languedoc region, southern France. These cases did not show the male predominance and early development usually found with this type of myeloma. Comparisons with a series of myelomas of all types detected in the same region during a similar period revealed an increased frequency of extramedullary clinical localizations, osteolytic lesions, anaemia and renal impairment. The monoclonal component was sometimes meagre, but it could be detected by electrophoresis on cellogel in 81 per cent of the cases. The lambda isotype, largely predominant, might account for these biological abnormalities and for a particularly sombre prognosis: the median survival was 11 months as against 29 months with myelomas of all types. There was no statistically significant correlation between any of the clinical and laboratory findings and the duration of survival.

Myeloma is a malignancy of plasma cells which are terminally differentiated B-lymphocytes. The diagnosis may be made incidentally at routine blood testing, when an abnormality is found in the plasma proteins on electrophoresis. More usually the patients are symptomatic, with bone pain, anaemia, evidence of renal failure, or the metabolic abnormalities associated with increased plasma calcium and urate levels. Effective treatment will extend survival from 7 to approximately 30 months and at the same time improve the quality of life. Treatment is multidisciplinary, prominently involves the professional nurse and may arbitrarily be divided into two stages. Firstly, reversible lesions, such as dehydration and plasma hyperviscosity must be corrected, hypercalcaemia and hyperuricaemia improved and, if necessary, renal dialysis undertaken. Secondly, but of equal importance, is the need for specific therapy to be directed against the tumour itself, and both cytotoxic agents and irradiation have an important role to play. More recently, newer approaches have included high dose chemotherapy and bone marrow transplantation.
