Background Drug–drug interactions between antiretroviral treatment (ART) and cytostatics may have a negative impact in the prognosis of people with HIV (PWH) and cancer. Objective The objective of this study is to evaluate the impact of the implementation of interdisciplinary management and the type of ART in PWH diagnosed with lymphoid neoplasms. Methods This is a multicentric, retrospective observational cohort study including PWH diagnosed with lymphoid neoplasm who started first-line chemotherapy between 2008 and 2020. Demographic, clinical and therapeutic variables were obtained from the electronic medical records and associated with 5-year progression-free survival (PFS) and overall survival (OS) using Cox proportional hazard models. Results A total of 118 individuals were included. Boosted ART was being used in 55 (46.6%) cases at the time of neoplasm diagnosis. The Infectious Diseases or the Pharmacy Department was consulted before starting chemotherapy in 79/118 (66.9%) cases. Interdisciplinary management resulted in fewer subjects taking boosted ART (17.7% versus 71.8%, P  < 0.001) and more subjects using unboosted integrase strand transfer inhibitor–based ART (74.7% versus 7.7%, P  < 0.001). The use of boosted ART with chemotherapy was associated with worse 5-year PFS (P  = 0.003) and 5-year OS (P  = 0.016). There was a trend towards better 5-year PFS and OS when interdisciplinary management was implemented, with significant differences for individuals receiving boosted ART at neoplasm diagnosis (P  = 0.0246 and P  = 0.0329, respectively). Conclusions Our findings underscore the significant impact of the type of ART on the prognosis of PWH undergoing chemotherapy. Encouraging collaborative management between oncologists, pharmacists and HIV teams for these patients enhances PFS and OS rates. [ABSTRACT FROM AUTHOR]

Introduction Rapid initiation of ART after HIV diagnosis is recommended for individual and public health benefits. However, certain clinical and ART-related considerations hinder immediate initiation of therapy. Methods An open-label, single-arm, single-centre 48-week prospective clinical trial involving ART-naïve HIV-diagnosed adults who started bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) within a week from the first hospital visit, before the availability of baseline laboratory and genotype results. The primary aim was to determine the proportion of people with at least one condition that would hinder immediate initiation of any recommended ART regimen other than BIC/FTC/TAF. Clinicaltrials.gov : NCT04416906. Results We included 100 participants: 79% men, 64% from Latin America, median age 32 years. According to European AIDS Clinical Society (EACS) and US Department of Health and Human Services 2023 guidelines, 11% (95%CI 6; 19) of participants had at least one condition that made any ART different from BIC/FTC/TAF less appropriate for a rapid ART strategy. Seventy-nine percent of the people started BIC/FTC/TAF within the first 48 hours of their first hospital visit. There were 16 early discontinuations (11 lost to follow-up). By week 48, 92% (95%CI 86; 98) of the participants of the ITT population with observed data achieved viral suppression. Eight grade 3–4 adverse events (AEs), five serious AEs and six ART-related AEs were identified. Adherence remained high. Conclusions BIC/FTC/TAF is an optimal treatment for rapid initiation of ART. However, additional strategies to improve retention in care must be implemented. [ABSTRACT FROM AUTHOR]

Objective: Patients with COVID-19 presented with an elevated prevalence of antiphospholipid antibodies (aPL) but the relationship with thrombosis is controversial. We analysed the persistence of aPL and their association with the clinical outcomes during hospitalisation in a cohort of COVID-19 patients. Patients and Methods: We conducted a prospective study including consecutive hospitalised patients with COVID-19 from Hospital Clínic of Barcelona between March 28th and April 22nd, 2020. Clinical outcomes during hospitalisation were thrombosis, intensive care unit (ICU) admission, and severe ventilatory failure. We determined both criteria and non-criteria aPL. Of note, in those patients with a positive result in the first determination, a second sample separated by at least 12 weeks was drawn to test the persistence of aPL. Results: One hundred and fifty-eight patients (59.5% men) with a mean age of 61.4 ± 14.9 years old were included. Thrombosis was present in 28 (17.7%) patients, severe respiratory failure in 47 (30.5%), and 30 (18.9%) patients were admitted to ICU. Sixteen (28.6%) patients were positive for the criteria aPL at both determinations and only two (3.6%) of them suffered from thrombosis during hospitalisations (both had aCL IgG). However, they presented with low titers of aCL. Of note, aPL were not related to thrombosis, ICU admission or severe respiratory failure. Conclusion: Although aPL were prevalent in our cohort of hospitalised COVID-19 patients and they were persistent in half of tested patients, most determinations were at low titers and they were not related to worse clinical outcomes.
