title: Serological markers as prognostic criteria for the course of HIV infection.
abstract: 576 serum samples from 139 HIV infected patients were analyzed for the presence of HIV antigens, as well as anti-core, anti-env and neutralizing antibodies. The results were correlated with the clinical and immunological stages of the patients. While almost all sera were positive for anti-env antibodies, only two thirds of the same sera had antibodies to core proteins. The average antibody titres, particularly of anti-core antibodies, decreased with the onset of clinical symptoms. The presence of p24 antigen could be demonstrated in only 16% of the sera. A positive reaction for core antigen seemed to be correlated with the absence of anti-core antibodies. Env specific neutralizing antibodies were found to be present in all of the sera analyzed in the LC5-test with a maximum neutralizing capacity observed in sera from WR 4 patients. A useful serological marker must fulfil two criteria, namely positive reactivity in the majority of sera examined and a broad range of antibody titres. None of the above described parameters meet these demands. Here we describe the search for new antibody markers, for example antibodies directed against HIV regulatory proteins.
