The Association between Sinusitis and Survival among Individuals Infected with the Human Immunodeficiency Virus

Abstract

The purpose of this study was to determine the association between sinusitis and survival among human immunodeficiency virus (HIV)–infected persons. All patients enrolled in the adult spectrum of disease data base from November 1, 1990 to November 1, 1999 were included. Patients were followed until death, loss to follow-up, or the end of the study on January 10, 2000. A Cox proportional hazard regression analysis was conducted to evaluate the association between sinusitis, various other cofactors, and survival. Of the 7513 HIV-infected patients followed, 57% were <35 years old, 59.5% were black, 78.5% were male, and 20.8% had an opportunistic infection (OI) at entry. The incidence of one or more diagnoses of sinusitis in the cohort was 14.5%. The mean entry CD4 count for the entire cohort was 347.8 (SD, 298.9) and the mean follow-up time was 33.2 months (SD, 25.7). The mean CD4 count at the time of sinusitis diagnosis was 391 (SD, 316). In the multivariate analysis, older age and lower CD4 cell count were associated with death. Sinusitis, gender, and race were not associated with survival. Sinusitis is frequent in individuals infected with HIV. After adjusting for level of immunodeficiency, age, gender, and race, sinusitis is not associated with an increased hazard of death. This may have implications for treatment, because a diagnosis of sinusitis does not portend a poor prognosis in individuals infected with HIV.
