Abstract

In 1980 AIDS appeared in the USA in the homosexual community. CHARACTERISTICS OF THE VIRUS: A particle of HIV is formed by two identical RNA chains that are packed within a center of viral proteins, and surrounded by a double layer of fosfolipids derived from the cellular membrane of the host. It starts with a severe infection, evolving in a progressive chronic infection reaching a final phase with a T CD4+ cellular count under 200 cells per mm3, with incident infections, neoplasias, consumption syndrome, renal dysfunction, and degeneration of the central system. CONSEQUENCES IN ALLERGIC REACTION: Reactions to the use of drugs are the most frequent form of hypersensitivity caused by HIV compared to the general population. In this condition, a profile of TH2 cytocines are produced and they induce the synthesis of IgE against the drugs. IgE levels have been related to the progression of this condition. The increase of IgE is a risk factor to allergic reactions against these medications, as well as a severity index.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
