Healthcare resource utilization and related cost of non-HIV comorbidity management in people with HIV in a Spanish cohort from 2007-2016.

Objective: To estimate the cost and healthcare resource utilization (HRU) associated with the prevalence of comorbidities in people living with HIV (PLWH) in a Spanish cohort over ten years.

Methods: A cohort study carried out at the HIV outpatient clinic of the University Hospital Virgen del Rocío based on data collected during 2007-2016. PLWH with at least one follow-up visit were included.

Efficacy and safety of antistaphylococcal penicillin or cephazolin-based combinations versus monotherapy for methicillin-susceptible Staphylococcus aureus infective endocarditis: A propensity score analysis of nationwide prospective cohort.

Objectives: We aimed to evaluate the usefulness of antistaphylococcal penicillin (ASP) or cephazolin-based combinations versus monotherapy in patients with native-valve infective endocarditis (IE) caused by methicillin-susceptible Staphylococcus aureus (MSSA).

Methods: Post-hoc analysis of a multicentre prospective cohort. We include patients from 2008 to 2022 with definite native-valve, left-side IE due to MSSA treated primarily with ASP/cephazolin.

Plasma concentrations of IL-6, MIP-1β, IP-10, and PTX-3 as predictors of the immunological response to antiretroviral treatment in people with HIV.

Despite effective antiretroviral therapy (ART), 15-30% of people with HIV experience poor CD4 T-cell recovery, termed immunologic non-responders (INR). This study aims to evaluate whether pre-ART plasma levels of interleukin-6 (IL-6), interferon gamma-induced protein-10 (IP-10), macrophage inflammatory protein-1-β (MIP-1β), and/or pentraxin-3 (PTX-3) could predict subsequent immunologic recovery. Seventy-four participants were enrolled and classified as INR and immunologic responders (IR) based on CD4/CD8 ratio increase over 24 months after starting ART.

HIV-1-DNA/RNA and immunometabolism in monocytes: contribution to the chronic immune activation and inflammation in people with HIV-1.

Background: Among people living with HIV-1 (PHIV), immunological non-responders (INR) experience incomplete immune recovery despite suppressive antiretroviral treatment (ART), facing more severe non-AIDS events than immunological responders (IR) due to higher chronic immune activation and inflammation (cIA/I). We analyzed the HIV-1 reservoir and immunometabolism in monocytes as a source of cIA/I.

Methods: Cross-sectional study in which 110 participants were enrolled: 25 treatment-naïve; 35 INR; 40 IR; and 10 healthy controls.
