    Notes: Background:  Heat-killed Listeria monocytogenes (HKL) potently stimulates interferon (IFN)-γ production in CD4 T-lymphocytes, and when used as adjuvant for immunotherapy, reduces immunoglobulin (Ig)E production and reverses established allergen-induced airway hyperreactivity (AHR) in a murine model of asthma. We asked if such treatment could decrease established peanut-induced anaphylaxis or cow's milk-induced food allergy in highly food-allergic dogs.Methods:  We therefore studied four 4-year-old atopic colony dogs extremely allergic to peanut (Group I), as well as five 7-year-old dogs very allergic to wheat, milk and other foods (Group II). All dogs experienced marked allergic symptoms, including vomiting and diarrhea on oral challenge with the relevant foods. The dogs were then vaccinated once subcutaneously with peanut or milk and wheat with HKL emulsified in incomplete Freund's adjuvant.Results:  Following vaccination of the allergic dogs with HKL and allergen, oral challenges with peanut (Group I) or milk (Group II) elicited only minor or no symptoms. In addition, skin test end-point titrations showed marked reductions for 〉10 weeks after treatment, and levels of Ara h 1-specific IgE in serum of peanut sensitive dogs, as demonstrated by immunoblotting, were greatly reduced by treatment with HKL plus peanut allergen.Conclusions:  Thus, HKL plus allergen treatment markedly improved established food allergic responses in dogs, suggesting that such an immunotherapy strategy in humans might greatly improve individuals with food allergy and anaphylaxis.

    Notes: Diverse neuropeptides are released by neuroendocrine and immune cells at the sites of allergic and inflammatory reactions. The neuropeptides and other neuromediators affect functions of smooth muscle, microvasculature and secretory cells, and are potent stimuli of mast cell, lymphocyte and other leucocyte contributions to such reactions. The distinctive immune sources, structures and cellular receptors for neuromediators suggest the possibility of novel pathogenetic mechanisms and levels of pharmacological intervention specific for neuroregulation of immunity and hypersensitivity.

    Notes: Infants born of allergic mothers but normal fathers, who had eczema and who were fed cows' milk, had a significantly greater incidence of asthma (P 〈 0.001) than infants with a similar history but who were breast-fed. An analysis of all breast-fed infants in the study showed that they were less likely to develop asthma than those who were bottle-fed (P 〈 0.06).There was a lower incidence of allergy in infants born of families with allergic mothers and normal fathers, than in families in which both parents were allergic (P 〈 0.02).In skin tests of both breast or bottle-fed babies, the two most common allergens eliciting reactions were egg and cat dander.
