title: [HIV infection: pathophysiology and its clinical features--clinical course and surrogate marker].
abstract: Clinical courses and several hematological and serological markers were evaluated in 34 patients with HIV infection (32 with hemophilia and 2 with homosexuality) who had been followed up at Shizuoka Prefecture Children's Hospital for 3 to 13 years, with the reference to the results observed in 1,082 patients with HIV infection registered with the Ministry of Health and Welfare Study Group, Natural History Committee. The results indicated as significant follow-up markers as (1) CD4- and CD8-positive lymphocyte count, (2) IgA, IgG and beta-2 microglobulin, (3) HIV p24 antigen and HIV culture isolation, and (4) serum HIV-RNA. Of these markers, the quantification of serum HIV-RNA seemed particularly useful for prognosis estimation, determination of therapy onset, and efficacy assessment of a given anti-HIV agent. In addition, we encountered 2 HIV-infected patients who seemed to meet the definition of long-term survivors. Factor analysis in these patients will be an important subject of investigation from a clinical point of view as well.
