Immunologic Parallels: Infectious Burden and Markers of Atopic Response Type
- 38 Downloads
The relationship between serological markers of infections and the atopic status of patients with allergy symptoms (rhinorrhea, nasal congestion, recurrent cough, asthma attacks, recurrent skin rashes combined with skin itching) and an increased total Ig E level was investigated. The determination of an infectious burden included screening for bacterial pathogens, protozoa, and helminths. All patients also had specific—food and inhalation—Ig E testing done. The relationship between the infectious burden and a specific atopic status is ambiguous—different pathogens have different types of effects such as opposite, synergistic, or no effect in mono-exposure. In addition, it has been shown that the pattern of pathogen influence on specific IgE response can vary in different age periods. This is due to both cumulative effects associated with a prolonged antigen burden and “switching” of the immune response that forms a hyperimmune IgE response as a protective phenomenon against helminths.
