Popis: Early diagnosis of human immunodeficiency virus (HIV) infection may be difficult in adults with acute or recent HIV infection and in infants with perinatally acquired HIV. Detection of HIV-specific immunoglobulin A (IgA) antibodies in infant serum by Western blot (immunoblot) has been suggested as a reliable method to identify HIV-infected infants, especially those over the age of 6 months, and as an adjunct to diagnosis of acute HIV infection in adults. We developed a simple enzyme immunoassay for detection of HIV-specific IgA, using standard commercially available reagents. Enzyme immunoassay was comparable to Western blot for detection of HIV-specific IgA in sera from adults (n = 216), older children (n = 49), and infants born to HIV-infected mothers (n = 65). Specificity was 100% and sensitivity ranged from 80 to 92%. IgA-enzyme immunoassay is a simple, highly sensitive method for detection of HIV-specific IgA antibodies and is easily adapted to the standard clinical laboratory.
