“…However, in the previous survey, a high prevalence of sensitization to DP as well as a strong association of this allergen with asthma and rhinitis was found, emphasizing the role of mites as triggers of allergic diseases (5). Several studies have addressed the capacity of BT to cause allergic diseases (10,11). As expected, most of these investigations have been carried out in regions with tropical or subtropical climates, although the presence of sensitization to BT in patients with asthma and/or rhinitis has also been detected in colder climates (12,13).…”

Our findings suggest that the greater diversity in prevalence of AR or AR/C in populations in these regions is in contrast to the lower diversity of AR or AR/C in the 'western populations (USA and Europe), which tend to be more uniform. This review provides a comprehensive database of the important allergens and triggers which are likely to influence the prevalence of allergic rhinitis in these diverse regions, where the prevalence of allergic rhinitis is increasing and its adverse impact on the quality of life of affected individuals is increasingly recognised.

“…Physical examination of the skin was performed using the criteria for diagnosis of atopic dermatitis established by Hannifin and Rajka and assessment of severity depending on the SCORAD index . Skin prick tests (SPT) were carried using allergenic extracts of cow's milk, hen's egg, Dermatophagoides pteronyssinus and Dermatophagoides farinae prepared as described previously and at a concentration of 0.3 mg/ml in a saline solution with 50% glycerol and 0.4% phenol. Control tests were performed with the diluent alone and with 1% w/v histamine dihydrochloride.…”

Background: We evaluated the influence of intestinal parasitic infection on food sensitization associated to the severity of Atopic Dermatitis (AD) in a group of Warao Amerindian pre-school children. Methods: Feces examinations were performed in fresh stool specimens. Diagnosis of AD was done according to Hannifin and Rajka criteria and SCORAD index. Skin prick tests (SPT) were performed using extracts of cow's milk (CM), hen's egg (HE), Dermatophagoides pteronyssinus and Dermatophagoides farinae . Serum CM and HE-IgE levels (ELISA) were measured. Quantikine (R&D systems) assays were used for the determination of IL-13, TNF-a IL-6, and sCD23 in supernatants of CM-and HE-whole blood stimulated samples. Results: Atopic Dermatitis was reported in 23% of the children. It was significantly (p < 0.0001) associated toward both CM and HE-SPT positivity (p < 0.001). Giardia duodenalis infection (37%) was associated to the presence of AD (p = 0.005) and to a significant increase in the levels of CM stimulated TNF-a (p ¼ 0:006), IL-13 (p = 0.01), sCD23 (p = 0.001), CM-IgE (p = 0.012) and CM-SPT (p < 0.0001). Similarly, G. duodenalis infection was particularly associated with the increase on the levels of HE-stimulated TNF-a (p = 0.001), sCD23 (p = 0.001), HE-IgE levels (p = 0.002) and HE-SPT (p = 0.001). Conclusion: Gut inflammation caused by G. duodenalis may enhance food allergic reactivity contributing to the manifestation of AD in these children. However, other environmental factors (not considered in this work) as well as an atopic background among the Warao population would also contribute to the presence of AD.
