Histamine inhibition of neutrophil lysosomal enzyme release: an H2 histamine receptor response.

Abstract: Human polymorphonuclear leukocytes treated with cytochalasin B release the lysosomal enzyme beta glucuronidase during contact with serum-activated zymosan particles. Histamine increases intracellular cyclic adenosine monophosphate and inhibits release of this enzyme. The H2 antihistamine metiamide blocks the histamine inhibition of lysosomal enzyme release and the increase in the intracellular adenoisine 3,5'-monophosphate of granulocytes. Chlorpheniramine, an H1 antihistamine, did not block the histamine inhibition of granulocyte lysosomal enzyme release.

Decreased adrenergic responses in lymphocytes and granulocytes in atopic eczema

Abstract: The physiologic and cyclic adenosine monophosphate (cAMP) response to beta adrenergic stimulation in lymphocytes and granulocytes was examined in atopic eczema. These cells were isolated by Ficoll-Hypaque gradient from 10 patients with atopic eczema, and their responses were compared to 10 normal subjects. In eczema, basal concentrations of cAMP were normal in both lymphocytes and granulocytes. Lymphocyte cAMP response in eczema was decreased both to epinephrine (10-5 M) and to isoproterenol (10-5 M) but normal to prostaglandin E1 (PGE1). It was also noted that the glycogenolysis response to isoproterenol was significantly less at 10-5 M in eczema, but the fall in glycogen was normal with PGE (10-5 M and 10-7 M). The inhibition of lysosomal enzyme release from granulocytes after zymosan stimulation was significantly less (p less than 0.01) in eczema with all concentrations of isoproterenol tested. There was also a decrease in cyclic AMP response to isoproterenol in the polymorphonuclear leukocytes. PGE1 inhibited lysosomal enzyme release and stimulated cAMP normally. In eczema, both lymphocytes and polymorphonuclear leukocytes have a decreased beta adrenergic response.

Alternaria IgG precipitins and adverse reactions.

Abstract: Late reactions consisting of fever, malaise, and swelling at the site, 4 to 6 hr after injections of Alternaria extract occurred in several patients receiving immunotherapy with Alternaria. These patients had in common serum IgG precipitins and exquisite leukocyte histamine release sensitivity to Alternaria. Such precipitins were 3 times more frequent in patients receiving Alternaria immunotherapy than a control group of patients receiving immunotherapy with other antigens. A prospective study revealed that 5 of 23 Alternaria-sensitive persons had precipitins before immunotherapy and another 6 developed precipitins during therapy. Only one of the 23 experienced a late Alternaria reaction. Thus, precipitins to Alternaria are common and do not seem to be the basis for the late reactions we observed. The finding of precipitins does not contraindicate immunotherapy.

Intranasal immunization with attenuated live influenza vaccine in asthma.

Abstract: Attenuated live intranasal influenza vaccine ("Alice") was given to 20 asthmatics and 9 control subjects. Pulmonary function tests were performed before and after, with emphasis on tests of small airways function (using flow volume curves with air and a helium-oxygen mixture). In subjects with a low influenza A antibody titer, there was a 4-fold rise in titer to the vaccine, whereas those subjects with a high titer showed no rise. There were no significant changes in pulmonary function in any parameters measured, and no significant symptoms were reported. We have concluded from this study that "Alice" appears safe for use in asthma and was capable of producing an antibody titer rise in persons with low titers.
