Consecutive serum samples obtained from 20 homosexual men during symptomatic primary HIV infection were examined by a variety of IgG and IgM antibody assays. All sera obtained 2-5 weeks after onset of disease contained IgM anti-HIV as demonstrated by an IgM antibody capture assay. The IgM antibodies appeared during the 2 first weeks of illness, reached peak titres at 2-5 weeks and declined thereafter to undetectable levels at 2-3 months after the onset of disease. By contrast, IgG anti-HIV appeared later, during the second week after the onset of symptoms, and did not reach maximal levels until the IgM response had waned. The first IgM antibodies to appear were directed against gag proteins. IgM antibodies against env antigens were found less frequently and later in the course of the disease. These results suggest that IgM antibody determination may be helpful in the diagnosis of early HIV infection as a possible addition to the combined use of antigen detection and a second generation ELISA, which, in the present study, was found to be highly reliable for diagnostic purposes.

D007075 Immunoglobulin M A class of immunoglobulin bearing mu chains (IMMUNOGLOBULIN MU-CHAINS). IgM can fix COMPLEMENT. The name comes from its high molecular weight and originally was called a macroglobulin. Gamma Globulin, 19S,IgM,IgM Antibody,IgM1,IgM2,19S Gamma Globulin,Antibody, IgM
D007118 Immunoassay A technique using antibodies for identifying or quantifying a substance. Usually the substance being studied serves as antigen both in antibody production and in measurement of antibody by the test substance.

D006678 HIV Human immunodeficiency virus. A non-taxonomic and historical term referring to any of two species, specifically HIV-1 and/or HIV-2. Prior to 1986, this was called human T-lymphotropic virus type III/lymphadenopathy-associated virus (HTLV-III/LAV). From 1986-1990, it was an official species called HIV. Since 1991, HIV was no longer considered an official species name; the two species were designated HIV-1 and HIV-2.

D000163 Acquired Immunodeficiency Syndrome An acquired defect of cellular immunity associated with infection by the human immunodeficiency virus (HIV), a CD4-positive T-lymphocyte count under 200 cells/microliter or less than 14% of total lymphocytes, and increased susceptibility to opportunistic infections and malignant neoplasms. Clinical manifestations also include emaciation (wasting) and dementia. These elements reflect criteria for AIDS as defined by the CDC in 1993.
