Introduction: HIV is an independent risk factor for cardiovascular diseases (CVD). There is insufficient information regarding comorbidities and cardiovascular risk factors in the Colombian HIV population. The aim of this study is to describe the prevalence of cardiovascular risk factors and comorbidities in patients from the HIV Colombian Group VIHCOL. Methods: This is a multicenter, cross-sectional study conducted in the VIHCOL network in Colombia. Patients 18 years or older who had at least 6 months of follow-up were included. A stratified random sampling was performed to estimate the adjusted prevalence of cardiovascular risk factors and comorbidities. Results: A total of 1616 patients were included. 83.2% were men, and the median age was 34 years. The adjusted prevalence for dyslipidemia, active tobacco use, hypothyroidism, and arterial hypertension was 51.2% (99% CI: 48.0%–54.4%), 7.6% (99% CI: 5.9%–9.3%), 7.4% (99% CI: 5.7%–9.1%), and 6.3% (99% CI: 4.8%–7.9%), respectively. Conclusions: In this Colombian HIV cohort, there is a high prevalence of modifiable CVD risk factors such as dyslipidemia and active smoking. Non-pharmacological and pharmacological measures for the prevention and management of these risk factors should be reinforced.

Introduction Long-term use of antiretroviral therapy (ART) for HIV infection might lead to the necessity of switching regimens. We aimed to analyze the reasons for the ART switch, the time-to-switch of ART, and its associated factors in a Colombian cohort. Methods We conducted a retrospective cohort in 20 HIV clinics, including participants ≥18 years old with confirmed HIV infection who underwent an ART switch from January 2017 to December 2019 with at least 6 months of follow-up. A time-to-event analysis and an exploratory Cox model were performed. Results 796 participants switched ART during the study period. The leading cause of ART switch was drug intolerance ( n = 449; 56.4%) with a median time-to-switch of 12.2 months. The longest median time-to-switch was due to regimen simplification (42.4 months). People ≥50 years old (HR = 0.6; 95% CI (0.5–0.7) and CDC stage 3 at diagnosis (HR = 0.8; 95% CI (0.6–0.9) had less hazard for switching ART over time. Conclusions In this Colombian cohort, drug intolerance was the main cause of the ART switch, and the time-to-switch is shorter than reports from other countries. In Colombia, it is crucial to apply current recommendations for ART initiation to choose regimens with a better tolerability profile.

BackgroundThe use of effective antiretroviral therapy (ART) has shown to modify the trend of AIDS-defining malignancies (ADM) toward non-AIDS defining malignancies (NADM); however, Latin America is a region with a known late presentation of HIV/AIDS and late initiation of ART, which could not result in averting the incidence of ADM. The epidemiology of cancers that define or not AIDS in people living with HIV in Colombia is not known.MethodsThe purpose of our study was to identify the trend of ADM and NADM and the effect of ART in a collective cohort of 15 centers of 8 cities in Colombia. After the institutional review board approval, the study was conducted as a retrospective chart review of patients with any diagnosis of cancer presented after the diagnosis of HIV and a year before. Demographic and clinical data related to the HIV infection, ART treatment, and cancer diagnosis were analyzed with Stata 12 software, and associations between different variables were made using univariate and bivariate analyses.ResultsA total of 415 patients with malignancies were included since 1986 (table). Most common cancers were Kaposi sarcoma (n = 227; 54.7%), and non-Hodgkin lymphoma (n = 80, 19,3%). Median CD4+ cell count was very low in this population (median 115.5, P25-75 39.5–243) at the time of HIV diagnosis. Most common NADM were skin cancer (n = 22; 5.3%) and Hodgkin lymphoma (15; 3.6%). The ratio of ADM:NADM was 0.5 before 1995 and increased progressively up to 3.0 after 2010 (P = 0.001) (figure). By bivariate analysis, we found a correlation of ADM with older age (P < 0.001), male gender (P = 0.03), recent years (P < 0.001), lower CD4 and higher VL at the time of cancer (P < 0.0001 for both), and mortality (P = 0.027). Cancer-associated mortality was 3.9%.ConclusionThe trend for diagnosis of ADM in Colombia is increasing despite antiretroviral treatment and exceeds NADM diagnosis. Potential explaining factors are the late presentation and initiation of ART, and poor treatment success in this population. Special efforts are required to diagnose and treat HIV patients in Colombia to avert this worrying trend. Disclosures All authors: No reported disclosures.
