The sera of 46 patients with multiple myeloma were examined for the presence of anti-tuberculosis (TB) glycolipids antibodies. In positive sera samples, anti-polynucleotides, anti-histones, anti-cardiolipin, anti-Sm and anti-RNP activities were sought. Antibodies against three different mycobacterial glycolipids were detected in 10 of the 46 sera. Three (P429, P557, P5) showed high titres of antibodies against all three different TB glycolipids. Of the 10 reactive samples, two antibodies were purified (P429, P557). P557 reacted with various polynucleotides and other antigens tested (Sm, RNP, cardiolipin, histones). One immunoglobulin (P207) which showed high activity against Sm and RNP had no activity against TB glycolipids and was employed as a control. The cross-reactivity between mycobacterial glycolipids and the nuclear antigens was further established by bi-directional competition assays with P429 and P557. Our study shows a high incidence (22%) of anti-TB glycolipids antibodies in sera of patients with monoclonal gammopathies, some of which show anti-DNA and other anti-nuclear antigens activities. This is additional evidence for the mycobacterial-nuclear antigen cross-reactivity which may suggest a possible role of infection (e.g., tuberculosis) in autoimmune diseases.

To study the risk of death and causes of death among female patients with tuberculosis (TB), a total of 1,083 female patients who diagnosed as having active pulmonary TB and newly registered into the Nagoya TB registry between 1979-1981 were followed up till the end of 1983. During follow-up period 138 deaths (12.7%) were observed, a significantly higher rate than expected from the general population. Observed deaths (O) from all types of cancer (O/E ratio = 2.5), lung (6.4) and colorectal cancers (5.0), were significantly higher than that which was expected (E). The number of deaths from TB was naturally high (O/E ratio = 40.0, p less than 0.001). Malignant lymphoma and multiple myeloma also showed high relative risk. The smoking rate among the patients was 14%, about the same as with the general population. Excessive high rates of death from lung cancer were observed both among smoking and non-smoking cancer patients. Non-smokers showed a high proportion (60%) of adenocarcinoma. The proportion of the use of antituberculous drugs during the past five years was not different between the lung cancer group and the non-lung cancer group. Patients who died from cirrhosis of the liver showed more frequent use of antituberculous drugs than the others. Factors causing excess incidence of colorectal cancer remain unknown. It was suggested that some immunologic disorders in TB patients may play some role in the development of cancer.

Acute renal failure developed in a patient with a normal serum creatinine level, after treatment with rifampin was begun for tuberculosis. Renal biopsy revealed an obstructive nephropathy due to tubular casts. Immunoperoxidase and immunofluorescence studies demonstrated the presence of heterogeneous light chains within these casts. This unique drug-induced renal disease is discussed with reference to the literature and to possible analogies with myeloma kidney.

From January 1980 to September 1985, 82 patients with IA to IIIB clinical stage (CS) Hodgkin's disease were treated by three MOPP chemotherapy (CT) cycles followed by extended field radiotherapy (RT) including the spleen (30-40 Gy). 2 patients died during the treatment (medullary aplasia, pulmonary edema). 6 were in failure after three MOPP cycles; they received other CT; 3 died and 3 are alive in remission (survival: 2.5 to 3.5 yr). 74 were in complete remission (CR) after completion of treatment. 4 patients relapsed (all alive after re-treatment) and 4 died in first CR (tuberculosis, hepatitis, myeloma, unknown cause). At 6 yr, actuarial survival and relapse-free survival are respectively 89.8% for the 82 patients and 93% for those in CR. These good results are due to: the administration of CT before RT, limited to three cycles; identification of failures after CT; inclusion of the spleen in RT ports in all cases; and a short lumbo-aortic port in CS I and II.

A hospital-based case-control study of 153 multiple myeloma (MM) cases and 459 controls was conducted to evaluate the hypothesis that chronic or frequent infections or allergic and autoimmune diseases might be of higher prevalence in individuals who develop MM. Information was obtained by direct interviews of subjects. Controls were matched to cases on age, sex, race, and hospital. "Immune-stimulating conditions" included chronic infections such as pyelonephritis, urinary tract infections (UTIs), prostatitis, rheumatoid arthritis and other collagen vascular diseases, allergies, bronchitis, tuberculosis, cholecystitis, diverticulitis, and osteomyelitis. The overall odds ratio (OR) (odds of history of immune-stimulating conditions in cases versus controls) was 0.4 (95% confidence interval = 0.3-0.7) which suggested that cases had significantly less immune-stimulating conditions than did controls. The exposure rate for these conditions was high for cases (0.7) as well as for all control groups (0.8). These findings suggest that immune-stimulating conditions alone are not the causative factor in the etiology of MM, though they may play a role in the predisposed individual.

Monoclonal antibodies to Mycobacterium leprae were produced by the fusion of BALB/c splenocytes and lymph node cells to BALB/c myeloma (NSI/1) cells. Eleven monoclonal antibodies were characterized as to their reactivity with M. leprae and 18 other mycobacterial species by enzyme-linked immunosorbent assay and immunofluorescence. Two monoclonal antibodies reacted only with M. leprae, and the other nine showed unique patterns of reactivity by enzyme-linked immunosorbent assay. One monoclonal antibody (IIH9) reacted with a 68,000-dalton protein present in extracts from M. leprae, M. tuberculosis H37Rv, M. gastri, and M. smegmatis. Potential uses for these antibodies in serological tests and immunochemical analyses are discussed.

Supernatants from clones of human T lymphocytes that were responding to a purified Mycobacterium tuberculosis antigen were able to activate macrophages and macrophage-like myeloma cells (U937) to release increased amounts of the microbicidal agent hydrogen peroxide. The activity was not neutralized by monoclonal antibody against interferon-gamma (IFN-gamma), was greater than could be accounted for by the IFN-gamma activity in the supernatants, and was separated from IFN-gamma by high performance liquid chromatography. It is evident that IFN-gamma is not the only macrophage activator released by T lymphocytes responding to microbial antigen, and may not even be the main one to enhance antimicrobial activity in infections such as tuberculosis.

Thirty-two monoclonal antibodies (MoAb) to Mycobacterium tuberculosis H37Rv, M. bovis BCG and M. leprae were produced. The spleen cells of BALB/c mice immunized with sonicated or intact bacilli were fused with Sp2/0-Ag-14 myeloma cells. Many more antibody producing hybridomas were found when M. tuberculosis, rather than M. leprae, was used as the immunogen. The MoAb were characterized by an enzyme immunoassay and immunofluorescence on 16 mycobacterial species. The sodium dodecylsulphate polyacrylamide gel electrophoresis immunoperoxidase assay was used to determine the molecular weight of the antigens detected by the MoAb. Antigens of high, low and intermediate molecular weight were found. Some of the antigens were proteinaceous, others of a glycolipid nature. The immunofluorescence assay proved to be essential for the selection of MoAb since some MoAb reacted only in this assay and not in the enzyme immunoassay. The most specific clones were found in the fusions with spleen cells of mice immunized with intact rather than sonicated bacteria. One MoAb (F29-29) reacted only with M. tuberculosis H37Rv; one (F41-3) only with M. leprae and another (F29-45) reacted with M. tuberculosis and M. gastrii. Several MoAb only reacted with three mycobacterial species: M. tuberculosis, M. kansasii and M. gastrii. Others showed unique patterns of reactivity by enzyme immuno- and immunofluorescence assay. The potential use of the MoAb for the identification of mycobacteria and mycobacterial antigens is discussed.

The records of 52 patients with amyloidosis admitted to Groote Schuur Hospital, Cape Town, between January 1969 and August 1982 were analysed. The male: female ratio was 1,3:1 and the mean age was 49,3 years. Forty-eight per cent of the patients had secondary amyloidosis, 21% had primary amyloidosis, 11,5% had localized amyloidosis and 11,5% had amyloidosis associated with multiple myeloma. Tuberculosis, chronic pulmonary sepsis and other chronic infections were present in 88% and rheumatoid arthritis in 16% of the patients with secondary amyloidosis. The commonest features at diagnosis were proteinuria (70%), oedema (52%) and hepatomegaly (39%). The diagnosis of amyloidosis was established by renal, liver and rectal biopsy (either singly or in combination) in 82% of cases. The prevalence of amyloidosis at autopsy was 0,28%.

Of 30 bacterial species tested 18 stimulated DNA synthesis in human blood lymphocytes. The maximum response was after 3-4 days of culture suggesting a mitogenic effect. This was confirmed by the induction of polyclonal antibody production shown by a plaque assay. Most bacterial species increased the DNA synthesis in B-enriched lymphocytes and unseparated lymphocytes but had negligible activity on T-enriched lymphocytes. Among bacteria with a mitogenic effect and ability to induce polyclonal antibody production are Staphylococcus aureus, Haemophilus influenzae, Mycobacterium tuberculosis, Neisseria gonorrhoeae, Streptococcus group A and Streptococcus pneumoniae. In an attempt to define structure (s) on the B-lymphocyte surface responsible for the lymphocyte stimulation the binding of IgD, IgM, and HLA-A, -B and HLA-D antigens to different bacterial species was investigated. A high IgD binding to N. catarrhalis and H. influenzae and a moderate binding of IgD to streptococci was found. Binding studies employing radiolabelled IgD Fab- and Fc-fragments indicated that the binding probably involves the CHl-region of the IgD molecule. Three purified radiolabelled myeloma IgM M-components were all shown to be efficiently bound to many bacteria indicating that a part of the IgM molecule other than the antigen-combining site can be involved in attachment to bacteria. Highly purified detergent-solubilized HLA-A, -B and HLA-D antigens, when separately incorporated into liposomes, were bound efficiently to two strains of N. catarrhalis and to one strain of H. influenzae weakly to one strain of E. coli, but not at all to another strain E. coli. Preliminary experiments indicate that these bacteria-immunoglobulin and bacteria-HLA-antigen interactions lead to lymphocyte stimulation.
