A prospective, 1-year study was performed to determine the causes of an ESR greater than or equal to 100 in patients admitted to a general medical ward in Harare, Zimbabwe. An ESR greater than or equal to 100 was found in 101 (12%) patients. Infection (46 patients) was the commonest cause, followed by malignancy (25), connective tissue disease (17), renal disease (8) and liver disease (5). The frequency of an ESR greater than or equal to 100 in these diagnostic groups was infection (28%), malignancy (44%), connective tissue disease (71%), renal disease (30%) and liver disease (24%). Pneumonia was the commonest infection diagnosed and the commonest cause of a markedly elevated ESR. Although myeloma was only the second commonest malignancy diagnosed it was the commonest malignancy causing an ESR greater than or equal to 100. In the largest group, infection, there was a significantly increased mortality in patients with an ESR greater than or equal to 100.

Spin-label 14C-TEMPO-dichlorotriazine distribution in Fab- and Fc-fragments of monoclonal myeloma immunoglobulin IgG (lambda) 1 Bel, in their heavy and light chains, and tryptic fragments of chains was investigated. Radio-active spin label in proteolytic Fab- and Fc-fragments, in heavy and light chains, and in separate peptides was detected. 3 cm and 2 mm band ESR spectra of spin-labeled IgG in water solutions was studied. It was shown that the models of highly anisotropic motion, isotropic motion and slow isotropic motion of spin label around globule or the description of experimental ESR spectra of TEMPO-dichlorotriazine spin-labeled immunoglobulins do not work.

The case of a 48 year old woman is reported with confluent nodules on the base of her nose and adjacent infraorbital areas, isolated ones on her face, and endotracheal masses with severe lumen reduction. Histologically the dermis and chorion of the nasal and tracheal mucosa were infiltrated by normal looking plasma cells. There was an increased ESR and a polyclonal gammapathy but no radiological evidence of skeletal involvement, bone marrow infiltration by atypical plasma cells or Bence Jones proteinuria. Cobalt-therapy was rapidly effective in reducing the endotracheal masses. The skin lesions were unaffected by roentgen-therapy and by several chemotherapeutic schedules. Laboratory values almost reverted to normal and her general condition has been satisfactory for the last two years. The differential diagnosis with multiple myeloma and extramedullary plasmocytoma was discussed and the condition classified as chronic, probably benign, mucocutaneous plasma cell infiltration.

The analysis of individual biochemical and clinical variables in 121 patients with multiple myeloma showed that serum beta 2-microglobulin (S-beta 2m) had the most significant relation to survival. Other variables such as serum thymidine kinase (S-TK), serum lactate dehydrogenase (S-LDH), S-creatinine, haemoglobin (Hb), ESR, S-albumin, age and clinical stage were also significant. No such relationship was found with M-component, presence of light chains in urine, type of secreted immunoglobulin or S-calcium. The exclusion of clinical stage in the first multivariate analysis resulted in a model consisting of S-beta 2m, age and S-TK, none of the other variables gave additional information. When in the second multivariate analysis the basic variables involved in staging procedure were excluded and clinical stage included, stage III, but not stage II, was found to give additional information to the model described above. Individual analysis of the variables showed that Hb had the most significant relation to effect of initial therapy. Other significant variables were S-TK, S-beta 2m and age. When using the multivariate approach, Hb alone was found to contain all the relevant information.

A study of 75 myeloma patients diagnosed at the Kenyatta National Hospital, Nairobi, is presented. The male to female ratio was 1.7:1; the mean age +/- s.d. was 51.5 +/- 12.5 (range 16-80) years; the peak age incidence of 32% occurred in the sixth decade. A combination of: anaemia (81.3%), osteolytic lesions on X-ray skeletal survey (80%), bone pains (66.7%) and an ESR above 50mm/hr (77.3%) formed an important diagnostic tetrad. Other significant findings included: hypoalbuminaemia (76%), elevated leukocyte alkaline phosphatase (61.3%), uraemia (54.7%), upper respiratory tract infections (44%), elevated serum creatinine (34.7%), raised alkaline phosphatase (33.3%), pathological fractures (32%), hyperuricaemia (30.7%) and hypercalcaemia (29.3). The study confirms that the disease is not infrequent in indigenous Kenyan Africans as previous literature seemed to suggest. Poor prognosis was significantly (p less than 0.05) associated with hypoalbuminaemia, raised serum blood urea, hyperuricaemia and an elevated serum creatinine level.

The authors have analysed the difficulties of delayed diagnosis of multiple myeloma (MM) with renal lesion in 27 patients admitted to the clinic of therapy and occupational diseases of the I.M. Sechenov First Moscow Medical Institute over the last 10 years. Before admission to the clinic MM was presumably diagnosed in 6 patients only, 17 patients were referred to the clinic with the diagnosis of this or that renal disease, 3 with the diagnosis of hypertension and 1 with rheumatoid arthritis. The main symptom in all the patients was proteinuria (isolated or combined with raised ESR and/or anemia in scanty urinary sediment). Macrohematuria was occasionally noted in one patient at the onset of the disease, and in another patient the onset of MM was marked by tubulopathy. The correct recognition of MM with renal lesion was rare which was due to a variety of initial symptoms (sometimes they were poorly expressed) and underestimation of the diagnostic importance of the combination of proteinuria with raised ESR and/or anemia.

Five cases of histologically verified plasma cell myeloma in sclerotic skeletal foci and polyneuropathy are reported. Thirty similar cases were collected from the literature. They illustrate a special form of plasma cell neoplasia. The characteristic features are osteosclerosis, polyneuropathy resembling polyradiculitis, approximately normal hemoglobin concentration, bone marrow smears and ESR, low concentration of M-protein, and absence of Bence-Jones' proteinuria. Slow progesssion of the disease is a possible additional feature. It is hypothesized that autoimmune mechanisms are involved in the pathogenesis. This hypothesis is based on the observation of circulating immune complexes, positive Waaler's reaction and relative increase in the number of circulating B-lymphocytes.

The analysis of ESR spectra of spin-labeled human myeloma immunoglobulins M and E has shown the rotation of spin labels bound to carbohydrates to be restricted most probably due to close attachment of oligosaccharide chains to protein parts of molecules. The values of rotational correlation times for IgM, IgMs and Fc5, spin-labeled at carbohydrates, were found to be equal to 7,7 and 6 ns, respectively. These data pointed to the existence of internal lability of the Fc5 fragment. ESR spectra of IgE spin-labeled at carbohydrates also reflected restricted rotation of the spin label, but the presence of a more than one wide extremum spoke in favour of differences in the degree of immobilization between different oligosaccharide chains. The value of rotational correlation times calculated for IgE, spin-labeled at protein and carbohydrate moieties, were similar (60 and 66 ns). These data confirmed the previously found rigidity of IgE molecule as compared with IgG molecule.

Two patients with "primary" plasma-cell dyscrasia, one with IgG kappa multiple myeloma and another with delta type light chain disease, are reported. Both of them presented extraosseous tumor mass on the forehead as an initial problem. They had moderate to severe anemia, accelerated ESR and multiple osteolytic lesions in the x-ray bone survey. They did not show prominent monoclonal spikes in serum electrophoregram and physiological immunoglobulins were not decreased. Repeated bone marrow aspirates on these two cases did not reveal definite plasmacytosis and pathological diagnosis was established by tumor biopsy. Immunopathological correlations were made, with an emphasis on rational analysis and interpretation of monoclonal proteins.

Analysis of 2,547 cases of multiple myeloma (MM) reported in China in 1980s showed that the clinical manifestations are characterized by multipliey. High misdiagnosis rate (69%) and multiple complications. While the monoclonal protein had more than 25 immunological type, IgG myeloma was the commonest (43.1%). Light chain subgroup trended to have higher incidence of renal damage (76.9%). Plasma cell leukemia eventually developed in 30 cases. In order to improve diagnosis and avoid misdiagnosis, the key points are 1, to better the recognition of clinical features of MM. 2. patient should receive urine Bence-Jones protein, immunoglobulins, immunoeletrophresis, bone X-ray and multiple site bone marrow puncture whenever one of such manifestations as unexplained anemia, skeletal pain, proteinuria, elevation of ESR, hyperviscosity syndrome, hypercalcemia, hyperuricemia, elevation of alkaline phosphatase, pathological fractures and diffuse osteoporosis. 3. immuno-binding electrophoresis and immunofluorence antibody detection should be done for suspected cases with normal immunoglobulin level.
