    Notes: We have earlier suggested that bacteria-induced histamine release is caused by different mechanisms, including allergic and non-immunological mechanisms, and that the latter probably depends on lectin-mediated reactions. Two possibilities of lectin-mediated reactions were examined in this study, bacterial surface lectins bind to sugars on the basophil cell membrane leading to histamine release, and the reverse reaction where bacterial aminosugars react with lectins on the basophil cell surface. In the bacterial histamine release caused by the Staph. aureus strain Wood 46 it was possible to demonstrate a reverse reaction, but not a bacterial lectin-mediated reaction. The reaction seems to be complex, as lower concentrations of sugars might potentiate the release of histamine by binding to the target cell or bacteria, while the release is inhibited by higher concentrations.

    Determination of IgE-Containing Immune Complexes in Human Sera (1984)

    Notes: We studied the polyethylene (PEC) precipitability of monomeric human IgE, and of human IgE artificially complexed with rabbit anti-human IgE. At conditions where precipitation of monomeric IgE did not occur, from 0.2 to 20% of the complexed IgE was precipitated. The PEG precipitability of the complexes was inversely related to the IgE/anti-IgE ratio used for preparation of the complexes. From 1.5 to 19.2% of the IgE in the redissolved precipitates could be detected by use of a two-site IgE immunoradiometric assay, the percentage being highest for complexes formed at equivalence. We conclude that exact quantitation of circulating IgE immune complexes (IC) probably is impossible by any PEC precipitation assay. However, the optimized assay was found to be useful for identification of IgE IC in sera with total IgE concentrations below 5,000 U/ml. IgE IC were found in 5/20 sera from patients with Felty's syndrome, in 5/39 sera from patients with extrinsic allergy and high levels of specific IgE, and in 1/17 sera from immunized wasp allergies. No IgE IC were found in 20 normal human sera.

    Notes: In vitro formation of immune complexes was studied by 3H-serotonin release from human platelets by P. aeruginosa antigens in the presence of serum From 22 cystic fibrosis patients. chronically infected with mucoid P. aeruginosa (CF + P) and with a pronounced antibody response against these bacteria, and in 24 patients without P. aeruginosa (CF-P). All CF + P patients responded with 3H -serotonin release (16–34%), whereas CF-P patients released less than 15%. In the group of CF4-P patients the number of P. aeruginosa precipitins was correlated to the serotonin liter. Time courses indicated that SH-serotonin release was maximal between 2 and 5 min, and that no further release was observed up to 20 min. There was a gradual increase in 3H -serotonin release with higher platelet concentrations The response was not changed by complement inactivation. and fractionation of serum demonstrated that the serotonin release was dependent on the presence of the immuno-globulin fraction. These experiments support the suggestion of a type 111 reaction being invoked in the lung damage in CF + P patients and also suggest a possible involvement of serotonin in the inflammatory reaction during chronic P. aeruginosa lung infection.

    Possible Role of Histamine in Rheumatoid Arthritis (1981)

    Notes: Basophilocytes from patients with rheumatoid arthritis (RA) responded to leukocyte nuclei from normal persons with histamine release; a similar histamine release induced by the nuclear components RNA and DNA has been demonstrated previously. A role of histamine in RA is also supported by the findings of clinical improvement during treatment with H1 and H2 antihistamines in six of 12 patients with RA in active phase, whereas four showed definite deterioration.

    Bacterial Histamine Release by Immunological and Non-Immunological Lectin-Mediated Reactions (1984)
    Oxford, UK : Blackwell Publishing Ltd
    Allergy 39 (1984), S. 0 
    Details

    Notes: The mechanisms of bacteria-induced histamine release were examined in vitro in human leukocytes and rat mast cells. Three types of bacterial responders were found. In persons with IgE-bearing basophilocytes bacterial histamine release could be triggered by two different mechanisms, an IgE-dependent mechanism where removal of IgE abolished the release and a non-immunological mechanism where this was not the case. In responders with no IgE-bearing cells bacterial histamine release was caused by a non-immunological mechanism. The non-immunological mechanism was further substantiated by release in isolated mast cells from germ-free rats. These experiments suggest a direct interaction between bacteria and target cell, and experiments with multi-washed bacteria and bacteria cell wall preparations indicate the possibility of the bacteria wall interacting with the target cell. It is probable that the non-immunological mechanism depends on lectin-mediated reactions, since bacteria-induced histamine release was inhibited by lectin-binding sugars as is release caused by plant lectins.

    Type I Allergy to Normal Cellular Constituents in Chronic Inflammatory Bowel Disease? (1984)

    Notes: The possibility of autoimmune type I reactions to cellular constituents was investigated in 22 patients with ulcerative colitis, 12 with Crohn's disease, and in 22 healthy volunteers Nuclear components and colon mucosa fragments were tested as potential antigens by the basophil histamine release technique One of 12 patients with ulcerative colitis responded to sonicated leukocyte nuclei and one of 12 patients with Crohn's disease responded to both nuclei and RNA. Increased serum levels of total IgE and antinuclear antibodies of IgE class were found in one and three of the 24 patients, respectively Histamine release caused by colon mucosa fragments was not observed in a separate study consisting of 10 ulcerative colitis patients and 10 healthy volunteers. Autoimmune type I allergy to cellular‘constituents does not seem to be of significance for chronic inflammatory bowel disease and thus could not explain the involvement of tissue mast cells and eosinophils in this condition

    Pseudomonas Aeruginosa Allergy in Cystic Fibrosis (1980)

    Notes: Basophil histamine release by P. aeruginosa standard antigen was examined in cystic fibrosis patients chronically infected with mucoid P. aeruginosa (CF + P) and with pronounced antibody response against these bacteria, and in patients without P. aeruginosa infection (CF - P). All the patients showed eosinophil counts and total IgE, which did not differ significantly from that of normal persons. In the absence of patient's sera, histamine release was only found in two patients in the CF + P group, indicating that type I allergy to P. aeruginosa is not predominating in cystic fibrosis.In the presence of patients' sera significantly more of the CF + P patients responded to P. aeruginosa with histamine release compared with the CF - P patients. The response was lost by complement inactivation and regained by reconstitution of the complement activity. The involvement of a type III-mediated complement-dependent histamine release is therefore suggested in the pathogenesis of lung damage in cystic fibrosis.

    Notes: A double-antibody radioimmunoassay for measurement of grass pollen antigen-specific IgG in serum is described. Grass pollen antigens were used to show a correlation between the results obtained by this method and those obtained by measuring blocking antibodies by inhibition of antigen-induced leukocyte histamine release. The new technique described is convenient, sensitive, specific and reproducible and can be recommended for clinical use.

    Intrinsic asthma and bacterial histamine release (1982)

    Notes: Abstract In this study of intrinsic asthma (IA) in children the pathogenic role of bacteria in respiratory disease was elucidated by a basophil histamine liberation technique. Several strains of bacteria caused release of histamine from peripheral leukocytesin vitro. Normal, non-infectious and non-atopic children frequently responded in a similar fashion, although positive responses were less frequent. It seems that two different mechanisms of bacterial histamine release exist: interaction with the basophil-bound IgE and a direct interaction with the cell surface. It is suggested that the histamine release takes place only in the lung of IA patients, where a defective pulmonary barrier could permit the bacteria to enter, but not in healthy individuals.
