[Immunoglobulins E and human immunodeficiency virus infection (HIV)].

Except for Ig E, serum immunoglobulin abnormalities in persons with human immunodeficiency virus (HIV) infection have been well described. Serum IgE levels have been shown to rise with progressive disease. The authors evaluated IgE in 148 HIV-seropositive individuals with or without acquired immunodeficiency syndrome (AIDS). Mean serum IgE levels were compared between groups based on absolute CD4 lymphocyte counts or clinical status (CDC) and with a seronegative control group. Higher serum IgE levels were observed in seropositive-patients. A rise in IgE serum is common in patients with HIV infection; it could be link with an earlier dysregulation in the IgE synthesis. No correlation was found between IgE level and CD4 counts.
