ABSTRACT Effect of cholesterol on in vitro latex-specific IgE production by mononuclear cells from atopic dermatitis patients with latex allergy. Cholesterol enhanced latex-specific IgE production in a dose-dependent fashion, and maximal enhancement was achieved at 1 microg/ml. In contrast, cholesterol had no effect on latex -specific IgA or IgG4 production. Study for cytokine production revealed that cholesterol decreased latex-induced production of IFN-gamma and IL-12, while it increased latex-induced production of IL-4, IL-10 and IL-13. These results indicate that cholesterol skews cytokine pattern toward Th2 type. Collectively, cholesterol may increase allergen-specific IgE production, which may in turn aggravate allergic symptoms.

    ABSTRACT: Stress enhanced allergic skin wheal responses and allergen-specific IgE production. In contrast, mothers' kissing caused relaxation in infants, and kissing by lovers or spouses to atopic patients reduced allergic skin wheal responses. I studied the effect of kissing on production of allergen-specific IgE and cytokines in atopic patients. Twenty-four patients with mild atopic eczema and 24 patients with mild allergic rhinitis kissed with lovers or spouses freely for 30 min while listening to soft music. Just before and immediately after kissing, blood mononuclear cells were separated cultured for allergen, and production of allergen-specific immunoglobulin and cytokine was measured. Kissing selectively decreased allergen-specific IgE production with skewing cytokine pattern toward Th1 type. Kissing may alleviate allergic symptoms by decrease in allergen-specific IgE production.

    ABSTRACT: Cholesterol promotes Th2 immunity and allergic inflammation in rodents; whether this occurs in humans is unclear. Reports of both direct and inverse associations between serum cholesterol and atopy in different populations suggest that race and/or other demographic variables may modify these relationships. Aims OF THE STUDY: To determine the relationships between levels of three serum cholesterol measures [total cholesterol (TC), high density lipoprotein-cholesterol (HDL-C), and non-HDL-C] and atopy in a sample representative of the US population. Cross-sectional study of 6854 participants aged > or =6 years from the 2005-2006 National Health and Nutrition Examination Survey. In the overall population, adjusted odds ratios (AORs) per two-standard deviation increase in TC and non-HDL-C for biochemical atopy (defined as > or =1 allergen-specific IgE to 19 allergens) were 1.17 [95% confidence interval (CI), 1.00-1.38] and 1.19 (95% CI, 1.03-1.39), respectively. Interactions by race were noted for the two relationships (interaction P = 0.004 and P = 0.009, respectively) with non-Hispanic Whites (NHWs) having direct relationships [TC: AOR 1.27 (95% CI, 1.03-1.57); non-HDL-C: AOR 1.27 (95% CI, 1.03-1.56)] and non-Hispanic Blacks (NHBs) inverse relationships [TC: AOR 0.77 (95% CI, 0.62-0.95); non-HDL-C: AOR 0.86 (95% CI, 0.69-1.08)]. The adjusted HDL-C-atopy relationship was nonsignificant for NHWs and inverse for NHBs [AOR 0.77 (95% CI, 0.61-0.96)]. Relationships were independent of body mass index and serum C-reactive protein and unmodified by corticosteroid or statin usage. Results were similar using current hay fever/allergy as the atopy outcome. There are marked inter-racial differences in the relationship between serum cholesterol and atopy in the US population.

    ABSTRACT: Atopic dermatitis is a chronic inflammatory disorder of the skin that has become very common in childhood. Similarly, obesity has increased in the USA and developed countries to epidemic proportions. Recent clinical and epidemiological studies have demonstrated an association between obesity and atopic dermatitis in childhood. Obesity is associated with increased prevalence and severity of, and healthcare utilization from, atopic dermatitis. Furthermore, obesity may be a modifiable risk factor for atopic dermatitis, such that weight loss may prevent or perhaps alleviate atopic dermatitis. Future studies are needed to determine whether weight loss in obese individuals improves atopic dermatitis.
