title: Detection of anti-HIV-1 immunoglobulin M antibodies in patients with serologically proved HIV-1 infection.
abstract: Serum samples from 247 patients with positive HIV-1 IgG serology were investigated for specific IgM antibodies. We found that 109 also reacted positively with a least one antigen in an HIV-1 IgM Western Blot and only 31 in an HIV-1 IgM enzyme-linked immunosorbent assay (ELISA). It was shown that in some of the persons, specific IgM antibodies against the gp160/120, p66, p55, gp41, p24, and p17 antigens of the virus are synthesized at some time after infection. IgM antibodies to the endonuclease-related p31 antigen were observed in one serum only. IgM antibodies against the gp160/120, p66, gp41, and p17 antigens seemed to disappear early after infection. Those against the p55 and the p24 antigens were found in 62% and 75% of investigated cases, respectively. A direct correlation between the Western Blot patterns and the IgM ELISA results was not found.
