Sera from patients with adult T-cell leukemia and asymptomatic carriers of human T-cell lymphotropic virus type I (HTLV-I) from widely separated areas of the world reacted strongly in a standardized quantitative enzyme-linked immunosorbent assay procedure with HTLV-I viral antigen prepared from a strain isolated in the United States. There was a sharp differentiation of the values seen in the patients as compared with a normal population. Of the 35 acquired immune deficiency syndrome patients with Kaposi's sarcoma, only 2 were positive for HTLV-I antibodies in this test, and the distribution of the negative assay values in the other acquired immune deficiency syndrome patient sera was similar to that seen in the normal sera. Sera which contained extremely high levels of antibodies to other unrelated viruses (rubella virus, cytomegalovirus, and herpes simplex virus) all showed negative anti-HTLV-I results, in a pattern similar to the normal sera. Sera from patients with several autoimmune disease (systemic lupus erythematosus, rheumatoid arthritis, thyroiditis) as well as those with infectious mononucleosis or myeloma all also showed the normal distribution of negative results, in spite of the presence of very high levels of the autoantibodies, etc., associated with their illnesses.

The results of screening for antibodies against rubella, morbilli, mumps, herpes simplex, rota and Epstein-Barr virus in serum from patients with multiple myeloma are reported. Antibodies against herpes simplex virus were found in all samples, present in high titres in most samples. Antibody titres against the other five viruses were generally low. A possible association of common virus infections and myelomatosis is discussed.

Mice were immunized by three intraperitoneal and one intravenous injection of rubella haemagglutinin. Splenocytes from these mice were fused with the cells of a syngeneic myeloma cell line, and following culture for various periods of time, single-cell clones were derived by the technique of limiting dilution. A total of 139 clones were derived from 13 parent hybrid cultures. To date, four of these cloned cultures have been propagated as ascitic tumours in mice. The preparation of IgG from ascitic fluid and labelling of this antibody with 125I is described. Results indicate that the use of labelled monoclonal antibodies as indicator reagents in solid-phase IgM antibody capture assays for the detection of rubella-specific IgM results in enhanced performance of these tests.

Adenosine deaminase (adenosine aminohydrolase, EC 3.5.4.4; ADA) activity is widely distributed in human tissues and is highest in lymphoid tissues. Two ADA isozymes are known as ADA1 and ADA2. Human tissue extracts contained ADA1 predominantly. Meanwhile, ADA2 was the main component of serum ADA. ADA activity was significantly elevated in the sera from patients with hepatic diseases, hematological malignancies and infectious diseases. Serum concentrations of ADA1 were high in patients with acute leukemias, chronic myeloid blast crisis leukemia and acute liver injury. Serum ADA2 levels were raised in patients with adult T-cell leukemia, multiple myeloma (B-J type), infectious mononucleosis, rubella, acquired immunodeficiency syndrome, chronic hepatic diseases and tuberculosis. It is supposed that ADA1 is derived mainly from injured tissues or cells while ADA2 comes from stimulated T-cells.

Whereas patients with multiple myeloma (MM) have a well-documented susceptibility to infections, this has been less studied in other B-cell disorders, such as Waldenstrom's macroglobulinemia (WM) and monoclonal gammopathy of undetermined significance (MGUS). We investigated the humoral immunity to 24 different pathogens in elderly patients with MM (n = 25), WM (n = 16), and MGUS (n = 18) and in age-matched controls (n = 20). Antibody titers against pneumococci, staphylococcal alpha-toxin, tetanus and diphtheria toxoids, and varicella, mumps, and rubella viruses were most depressed in MM patients, next to lowest in WM and MGUS patients, and highest in the controls. In contrast, levels of antibodies specific for staphylococcal teichoic acid, Moraxella catarrhalis, candida, aspergillus, and measles virus were similarly decreased in MM and MGUS patients. Comparable titers in all study groups were seen against Haemophilus influenzae type b (Hib), borrelia, toxoplasma, and members of the herpesvirus family. Finally, a uniform lack of antibodies was noted against Streptococcus pyogenes, salmonella, yersinia, brucella, francisella, and herpes simplex virus type 2. To conclude, although MM patients displayed the most depressed humoral immunity, significantly decreased antibody levels were also evident in patients with WM and MGUS, particularly against Staphylococcus aureus, pneumococci, and varicella. Conversely, immunity was retained for Hib and certain herpesviruses in all study groups.

Attenuated live virus vaccinations are generally recommended 24 months following hematopoietic cell transplantation (HCT) in patients not receiving immunosuppressive therapy. To date, there are no data regarding the safety of live-attenuated herpes zoster or measles-mumps-rubella (MMR) vaccinations in multiple myeloma patients on maintenance lenalidomide or bortezomib following autologous HCT. One hundred thirty-seven multiple myeloma patients on maintenance lenalidomide or bortezomib post-auto-HCT who received either MMR or herpes zoster vaccine were analyzed and any adverse events documented in the medical record in the 42 days following vaccination were recorded. Patients were vaccinated a median of 25 months (range, 18-62) post transplant. The most common post-vaccination adverse event was upper respiratory tract infection (18/137 patients); no rash attributed to vaccine strains or other adverse outcomes potentially related to the vaccines were identified. MMR and herpes zoster vaccination were safe and well-tolerated in this cohort.

Common childhood infectious diseases have been associated with a reduced risk of following haematopoietic malignancies, but investigations on multiple myeloma (MM) are scarce. Information about 213 MM cases and 1128 healthy controls were obtained from a multicentre population-based Italian case-control study. The association between chickenpox, measles, mumps, pertussis and rubella and the MM risk was estimated by unconditional logistic regression, adjusting for age, gender and residence area. No association was found between MM risk and any considered infectious disease. The number of infections was slightly inversely associated with the risk of MM, but statistical significance was not reached (OR 0.87, 95% CI 0.55-1.4 for 1-2 diseases vs. none and OR 0.68, 95% CI 0.41-1.1 for 3-5 diseases, respectively, P = 0.131). We did not find a clear evidence that common infections during childhood are associated with the subsequent risk of developing MM.
