Background: There is limited recent evidence about infective endocarditis (IE) in HIV-infected patients. Our aim was to compare IE according to HIV infection presence. Methods: Consecutive inclusion of IE patients at 46 Spanish hospitals between 2008 and 2021. Results: From 5667 patients, 99 were HIV-infected (1·7%; 50 intravenous drugs users). Compared to patients without HIV, HIV-infected patients were more frequently male (84% vs. 67%), had younger median age (46 vs. 69 years), and less comorbidities, except liver disease (52% vs. 9%) and intravenous drug use (51% vs. 1%). They had more common tricuspid location (36% vs. 5%) and community-acquired IE (82% vs. 63%), vascular (29% vs. 17%) and cutaneous (22% vs. 7%) foci of infection, and Staphylococcus aureus aetiology (46% vs. 22%). Vegetations (84% vs. 72%), vascular phenomena (17% vs. 9%), splenomegaly (30% vs. 11%), and embolisation (41% vs 21%) were also more common. Surgical indication and surgery were less frequent in HIV-infected patients (54% vs 67%, 28% vs 47%, respectively). Median CD4 count in HIV-infected patients was 318 cells/mm3. In-hospital mortality (23% vs. 26%) and one-year mortality (25% vs. 32%) were similar in both groups. HIV infection was not independently associated with in-hospital (odds ratio 1·1, 95% CI 0·6–1·9) nor one-year mortality (hazard ratio 0·8, 95% CI 0·4–1·3). Conclusions: In the combined antiretroviral therapy era, less than 2% of IE patients have HIV infection. HIV-infected patients have a different clinical profile than those without HIV, but the presence of HIV does not seem to impact on IE prognosis.
