Background. Invasive pneumococcal disease (IPD) is an important cause of morbidity among individuals infected with human immunodeficiency virus (HIV).

description Background. Invasive pneumococcal disease (IPD) is an important cause of morbidity among individuals infected with human immunodeficiency virus (HIV). We described incidence and risk factors for IPD in HIV-infected and uninfected individuals. Methods. Nationwide population-based cohort study of HIV-infected adults treated at all Danish HIV treatment centers during 1995–2012. Nineteen population-matched controls per HIV-infected individual were retrieved. The risk of IPD was assessed using Poisson regression. Results. The incidence of IPD was 304.7 cases per 100 000 person-years of follow-up (PYFU) in HIV-infected and 12.8 per 100 000 PYFU in HIV-uninfected individuals. After adjusting for confounders, HIV infection (relative risk [RR], 24.4 [95% confidence interval [CI], 23.7–25.1]), male sex (RR, 1.20 [95% CI, 1.16–1.24]), increasing age (per year) (RR, 1.03 [95% CI, 1.03–1.04]), and calendar period (pre-cART RR, 2.80 [95% CI, 2.70–2.91] compared with late cART) were significantly associated with an increased risk of IPD. Among HIV-infected individuals, male sex (RR, 1.57 [95% CI, 1.49–1.66]), smoking (RR, 1.34 [95% CI, 1.26–1.42]), and injecting drug use (RR, 2.51 [95% CI, 2.26–2.67]) were associated with an increased risk of IPD. Detectable viral loads (RR, 1.88 [95% CI, 1.79–1.98]) and a relative fall in CD4 T-cell counts were also associated with an increased risk (≥500 to 350–500 CD4 T cells/μL: RR, 1.29 [95% CI, 1.21–1.37] and
