Background: Treatment has improved HIV infection prognosis, but whether risk and health care seeking behavior have improved is unclear. Methods: New entrants to HIV care at University Hospitals of Cleveland, Ohio, between 1995 and 2002, with no history of AIDS-defining illnesses or antiretroviral exposure were included. Results: Of new patients, 806 (80%) met the inclusion criteria. Median age increased during the study period(35.2 to 38.6 years; P < .001); proportions of females and non-whites increased nonsignificantly. Prevalence of AIDS-defining illnesses decreased from 1995 to 1996 (25.0% to 14.2%; P <.001) but remained stable thereafter. Category B conditions and sexually transmitted diseases decreased significantly(31.7% to 9.1%; P = .039 and 22.5% to 8.0%; P = .003), as did hepatitis B and C seroprevalence (8.3% to 3.6%; P = .05 and 26.2% to 14.3%; P = .003). Median CD4 counts and HIV RNA did not change significantly. Conclusions: Prevalence of Category B conditions, sexually transmitted diseases, and hepatitis B and C declined significantly in this study. Prevalence of AIDS-defining illnesses decreased early in the highly active antiretroviral therapy era only, whereas markers of HIV disease stage remained stable, suggesting a need for earlier recognition of infection. Decreasing sexually transmitted diseases and hepatitis coinfections suggest that HIV infection is increasingly seen in populations previously perceived at lower risk.
