Abstract: There has been a global increase in prevalence of allergic diseases. This is particularly so in developed and in urban centres of developing countries. At the same time, in rural areas of developing countries helminth infections are still highly prevalent. The immune response against helminths and allergens is generally characterized by high levels of IgE and increased numbers of Th2 cells, eosinophils, and mast cells, yet the clinical outcome with respect to immediate hypersensitivity and inflammation is clearly not the same. High levels of IgE are seen to allergens during helminth infections; however, these IgE responses do not translate into allergy symptoms. The role of socio-economic status (SES) which can be intertwined with presence or absence of helminth infections, has been examined in relation to development of allergic disorders in several studies. This thesis summarizes the evidence of the association between helminth infections and allergic disorders. It discusses how helminth infection can lead to IgE cross-reactivity with allergens and how this IgE has poor biological activity. The studies presented in this thesis shed light on the relationship between helminth infection, SES and atopic disorders in a developing country (Indonesia) where large differences in life-style, environmental exposure and SES are seen.
