AB BACKGROUND: Atopic symptoms such as sinusitis, eczema, and wheezing are
common in human immunodeficiency virus (HIV)-infected children.
OBJECTIVE: To determine whether IgE levels are increased in
HIV-seropositive children, and to determine whether there is a
relationship between IgE, stage of disease, and atopic symptoms.
METHODS: Levels of serum IgE and parameters of HIV infection, including
absolute CD4 and CD8 T lymphocyte counts, and serum levels of neopterin,
beta 2 microglobulin and HIV P24 antigen were measured. Clinical
parameters including stage of disease, opportunistic infections, and
atopic symptoms were recorded. RESULTS: IgE was increased prior to 1
year of age and mean levels remained elevated through age 6 years but
regressed to the normal mean in children ages 7 to 9. There was a strong
association between increased IgE and the presence of secondary
disseminated or systemic diseases including pulmonary lymphoid
hyperplasia, Pneumocystis carinii pneumonia, or disseminated
cytomegalovirus infection. There was no correlation between CD4 levels
and IgE levels (r = .03). The relationship between IgE and serum P24
antigen, beta 2 microglobulin, and neopterin levels was also analyzed. A
weak positive correlation was found only with serum p24 antigen levels
(r = .24). Atopic symptoms were found in a subpopulation of these
children, with wheezing occurring in 27% of all patients, atopic
dermatitis in 5%, drug reactions in 7% and sinusitis in 8% but IgE
levels were not significantly elevated in patients with atopic symptoms.
CONCLUSIONS: These findings demonstrate that serum IgE is increased in
children very early after HIV infection and that IgE levels increase in
association with HIV-associated systemic disease. Increased IgE is not
associated with atopic symptoms in children.
