Lung Function in Women with and without HIV.

Academic Article

Abstract

  • BACKGROUND: Prior studies have found that HIV infection is associated with impaired lung function and increased risk of chronic lung disease, but few have included large numbers of women. In this study, we investigate whether HIV infection is associated with differences in lung function in women. METHODS: This was a cross-sectional analysis of participants in the Women's Interagency HIV Study (WIHS), a racially and ethnically diverse multicenter cohort of women with and without HIV. In 2018-2019, participants at all nine clinical sites were invited to perform spirometry. Single-breath diffusing capacity for carbon monoxide (DLCO) was also measured at selected sites. The primary outcomes were the post-bronchodilator forced expiratory volume in one second (FEV1) and DLCO. Multivariable regression modeling was used to analyze the association of HIV infection and lung function outcomes after adjustment for confounding exposures. RESULTS: FEV1 measurements from 1,489 women (1,062 HIV+, 427 HIV-) and DLCO measurements from 671 women (463 HIV+, 208 HIV-) met standards for quality and reproducibility. There was no significant difference in FEV1 between women with and without HIV. Women with HIV had lower DLCO measurements (adjusted difference, -0.73  mL/min/mmHg, 95% CI -1.33 to -0.14). Among women with HIV, lower nadir CD4 + cell counts and hepatitis C virus infection were associated with lower DLCO measurements. CONCLUSIONS: HIV infection was associated with impaired respiratory gas exchange in women. Among women with HIV, lower nadir CD4 + cell counts and hepatitis C infection were associated with decreased respiratory gas exchange.
