    Journal: Ann Allergy Asthma Immunol; 1997 Mar; 78(3):301-6. PubMed ID: 9087157.
    Abstract:
    BACKGROUND: Progression of human immunodeficiency virus type 1 (HIV-1) infection to the acquired immunodeficiency syndrome (AIDS) is associated with elevated total IgE; however, previous cross-sectional studies have differed in their assessment of concurrent changes in allergic disease prevalence. OBJECTIVE: Assessment of changes in aeroallergen-specific IgE during progression from early to late HIV disease. METHODS: Total IgE, aeroallergen-specific IgE (rye grass, ragweed, Alternaria, dust mite, and cat), IFN-gamma, IL-4, and soluble CD23 (sCD23) were measured in a longitudinal study of 20 subject who had progressed from early-HIV infection (mean CD4 lymphocyte count of 650/mm3) to AIDS (mean CD4 lymphocyte count of 40/mm3) over an average of 4 years. RESULTS: Prevalence of positive aeroallergen specific-IgE assays in early HIV disease (T1 subjects with 13 positives) decreased with progression to late disease (five subjects with nine positive, P = .057), while total IgE increased from a median of 69 to 116 IU/mL. IFN-gamma and IL-4 were unchanged, while sCD23 decreased from a median of 72 to 9 U/mL (P = .0005) with disease progression in the full cohort. In contrast to other subjects, the subgroup of individuals with total IgE > 150 IU/mL in both early and late HIV disease demonstrated an increased frequency of aeroallergen-specific IgE. CONCLUSIONS: The elevation of total IgE associated with rapid HIV-1 disease progression was unexplained by concurrent changes in aeroallergen-specific IgE, IL-4, IFN-gamma, or sCD23. Overall, aeroallergen-specific IgE expression was less prevalent with HIV-1 progression, except in those individuals with elevated total IgE both before and after progression to AIDS.
