Cold non-HLA lymphocyte cytotoxins were found to be principally reactive against B lymphocytes. These antibodies were studied in 1335 patients with a wide range of diseases such as systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), scleroderma, Hashimoto's disease, asthma, diabetes, lymphoma, psoriasis, leukemia, multiple sclerosis, and also in healthy donors. Antibodies reactive to B lymphocytes in the cold or warm test conditions were not directed against HLA specificities. Since B lymphocytes differ from T lymphocytes principally in that they have surface immunoglobulin, it is postulated that at least one target antigen of cold lymphocyte cytotoxins is not a virus, infectious agent, or a genetically determined structural antigen, but, rather, simply immunoglobulin.

In a statistical analysis of more than 2000 IgE estimations, the authors corroborate the importance of this determination for diagnosis of asthma, eczema and rhinitis. Serum IgE levels are also elevated in parasitic diseases, and may be elevated in some other cases in which there are several disorders, such as cirrhosis and leukemia.

In the Tri-State Leukemia Survey, the history of diseases in 605 adult male leukemia cases 15 years and older and in 668 adult male population controls was examined. These diseases occurred at least 1 year before leukemia was diagnosed. The data were based on respondents' answers that the disease was diagnosed by a physician; the respondent was either the subject or his spouse. Of 30 diseases studied, 7 showed an excess among the patients with leukemia: infectious hepatitis, eczema, psoriasis, diabetes, arthritis and rheumatism, heart disease, and ankylosing spondylitis. Mumps had a lower reported occurrence among the cases, whereas pneumonia was less frequent in acute lymphatic cases than in population controls. Three diseases occurred significantly less in controls than in persons with specific histologic types of leukemia. Our data revealed a more frequent history of herpes zoster (shingles) in chronic lymphatic leukemia, more hives in acute chronic myeloid cases, and meningitis in acute myeloid leukemia. When we only considered the patients' responses, more of them admitted having had acne than did our controls. The remaining diseases--childhood viral diseases, infectious mononucleosis, smallpox, typhoid fever, dysentery, scarlet fever, tuberculosis, asthma, hay fever, and goiter did not occur more frequently in cases than in controls. The findings were consistent with evidence from previous laboratory and clinical studies. The increased occurrence of infectious hepatitis in our case series is consistent with the findings of other studies showing an increased frequency of Australia antigen in patients with hepatitis, leukemia, and Down's syndrome.

Intravenous human immunoglobulins (IVIG) are valuable in the treatment of several immunodeficiency and autoimmune diseases. The classic, well-known indications are primary hypogammaglobulinaemic conditions, immune thrombocytopenia and Kawasaki's syndrome. IVIG's content of specific antibodies toward a series of known, pathogenic microorganisms has led to the treatment of a number of infectious conditions and IVIG has a documented effect on AIDS in children, prophylactically in cases with potentially life-threatening CMV infections in certain types of transplants and prophylactically in hypogammaglobulinaemic patients with the most common variety of leukaemia, chronic lymphocytic leukaemia. Immunotherapy with IVIG in diseases of autoimmune character such as acute and chronic demyelinating neuropathy has recently shown promising results and encouraging reports have been published in the treatment of severe, steroid-dependent asthma, juvenile chronic arthritis and systemic vasculitis and dermatomyositis where IVIG possibly has a favourable immunomodulating effect on the patient's immune response. Future treatment will probably consist of polyvalent immunoglobulins as well as monoclonal or recombinant monovalent antibodies.

The IgE-dependent activation of mononuclear phagocytic cells through their capacity to express low affinity IgE receptors (Fc epsilon RII) has been proposed as a mechanism for the development of airways inflammation in allergic asthma. This Fc epsilon RII expression leads to the IgE-dependent production of the potent pro-inflammatory cytokines IL-1 beta and TNF-alpha. Expression by monocytes of Fc epsilon RII is regulated by several cytokines including interleukin-4, gamma- and alpha-interferons, and granulocyte-macrophage and macrophage colony stimulating factors. An anti-inflammatory effect of nedocromil on monocytes has been proposed as a possible mechanism for its anti-asthma activity. We therefore investigated the capacity of nedocromil to modulate mononuclear phagocyte Fc epsilon RII expression and cytokine production. We used an anti-Fc epsilon RII antibody and flow cytometric analysis to assess the capacity of nedocromil to modulate cytokine-induced Fc epsilon RII expression in normals and asthmatics. Monocytes, THP-1 monocyte leukaemia cells, and alveolar macrophages were exposed to varying concentrations of these cytokines for 48 hr at 37 degrees C with or without the additional presence of nedocromil (1-10 microM) and the per cent of monocytes expressing Fc epsilon RII was determined. No changes in Fc epsilon RII expression were observed. Subsequently, we investigated the capacity of nedocromil to affect the capacity of IgE plus anti-IgE complexes, allergen, and LPS (16 hr/37 degrees C) to stimulate IL-1 beta and IL-6 production. No changes were observed when nedocromil was applied concomitant with the stimulus.(ABSTRACT TRUNCATED AT 250 WORDS)

Machining fluids are widely used in a variety of common industrial metalworking operations to lubricate and cool both the tool and the working surfaces. Previous studies have suggested elevated respiratory, digestive, and skin cancers in exposed populations. This cohort study was initiated to assess whether long-term exposure to machining fluids in the course of machining, grinding, and other cutting operations is associated with excess cancer mortality. The cohort includes more than 45,000 automobile production workers from 3 plants, almost 1 million years of follow-up, over 10,000 deaths, and an extensive exposure assessment component. Standardized mortality ratios (SMRs) have been estimated for each of the 3 plants, using both U.S. as well as local populations as reference. Relative risks of 1.2-3.1 have been observed for several specific respiratory and digestive cancers of a priori interest, including cancer of the stomach, large intestine, pancreas, lung, and larynx. In addition, elevated risks for leukemia and asthma were noted. Future exposure-response analyses will provide the opportunity to identify relatively modest excesses in cause-specific mortality risk associated with exposure to specific types (straight, soluble, or synthetic), additives, or components of machining fluids.

The role of selected prior medical conditions in the etiology of hematopoietic malignancies was examined in a case-control study of members of two regional branches of the Kaiser Permanente Medical Care Program (USA). Past history of chronic infectious, autoimmune, allergic, and musculoskeletal disorders was abstracted from medical records for leukemia (n = 299), non-Hodgkin's lymphoma (NHL, n = 100), and multiple myeloma (n = 175) cases and matched controls (n = 787). Little difference was found between cases and controls for most of the chronic conditions evaluated, including sinusitis, carbuncles, urinary tract infections, pelvic infections, herpes zoster, asthma, rheumatoid arthritis, psoriasis, bursitis, and gout. Only three statistically significant elevated risks were found, i.e., with combined disc disease myeloma among patients with prior eczema and disk and other musculoskeletal conditions, and NHL following tuberculosis. Only two of these associations showed consistent patterns by sex and geographic region (myeloma with eczema and with musculoskeletal conditions). While prior history of eczema and musculoskeletal conditions may slightly increase risk of myeloma, this study provided little if any support for an association of chronic infectious, autoimmune, allergic, and musculoskeletal conditions with subsequent occurrence of the leukemias or NHL. Additionally, these data did not support a role for chronic antigenic stimulation, as defined in previous epidemiologic studies, in the etiology of hematopoietic malignancies.

From a total of 95 children treated on a long-term basis with corticosteroids as part of a chronic dialyzation programme on account of asthma, juvenile chronic arthritis and leukaemia in 23 (24%) posterior subcapsular cataract (PSC) was diagnosed. The authors consider as the risk factor the amount of corticosteroids in relation to body weight rather than the absolute dose. The danger of PSC develops after one year's administration of 0.3 mg/kg/day Prednisone or its equivalent. This fact is documented by two case-histories indicating the chronology of development of PSC in two-year-old patients, from clear lenses to the most severe affection in the group. The absolute amount of Prednisone was 5-10 mg, i. e. 0.5 mg/kg/day. In one of the two patients the cataract of one eye had to be operated. The patients should have dispensary examinations after one year and subsequently after six-month intervals in case of continuing corticosteroid treatment. An interesting finding was the observation of the incipient stage of PSC--a double dissociation in the area of the posterior "Y" seam.

Investigated age and gender differences in adjustment to chronic disease in children suffering from one of five conditions: diabetes, asthma, cardiac disease, epilepsy, and leukemia. Ratings of adjustment and disease-related restrictions were obtained separately from mothers and fathers. Factor analysis of the adjustment scale yielded 6 subscales which differentiated between children in terms of age and disease type, and to a lesser extent, gender. Mothers' and fathers' ratings of adjustment and restrictions were comparable, though fathers made less differentiation on the basis of disease or age. For both parents, perceived restrictions of the disease were associated with poorer adjustment in the child, and this was particularly reflected on indices of peer relations and work.

The effect of nedocromil sodium on the generation of neutrophil-derived histamine-releasing activity (HRA-N) from human peripheral blood neutrophils and on the secretory effects of HRA-N and anti-IgE on rat basophil leukemia (RBL) cells was studied. Nedocromil sodium caused dose-related inhibition of HRA-N generation by human neutrophils (10(-7) to 10(-4) mol/L; inhibitory concentration of 50%, 1.5 x 10(-8) mol/L). In contrast, the presence of nedocromil sodium had no effect on HRA-N-mediated serotonin release from RBL cells. In five experiments, with one crude and four partially purified HRA-N preparations, serotonin release from RBL cells exposed to native HRA-N or HRA-N in the presence of nedocromil sodium (10(-4) mol/L) was 28% +/- 6% and 26% +/- 5%, respectively. Similar results were found with all concentrations of nedocromil sodium studied. Preincubation of RBL cells with nedocromil sodium (10(-4) mol/L) for 0 to 60 minutes also did not affect HRA-N-mediated serotonin release. Likewise, nedocromil sodium (10(-7) to 10(-4) mol/L) had no effect on anti-IgE-induced serotonin release from RBL cells. In 10 experiments, anti-IgE alone or in the presence of nedocromil sodium (10(-4) mol/L) induced 32% +/- 6% and 32% +/- 5% serotonin release, respectively. Preincubation of RBL cells with nedocromil sodium before anti-IgE exposure had no further effect. This is the first study of pharmacologic manipulation of the generation of a histamine-releasing factor. It is hypothesized that one possible mechanism whereby nedocromil sodium protects against asthma and allergic rhinitis is through inhibition of HRA-N generation.
