Predictors of poor health-related quality of life among people living with HIV aged ≥60 years in the PISCIS cohort: Findings from the Vive+ project.

INTRODUCTION: Advancements in and accessibility to effective antiretroviral therapy has improved the life expectancy of people living with HIV, increasing the proportion of people living with HIV reaching older age (≥60 years), making this population's health-related quality of life (HRQoL) more relevant. Our aim was to identify the determinants of poor HRQoL in people living with HIV aged ≥60 years and compare them with those of their younger counterparts. METHODS: We used data from the 'Vive+' study, a cross-sectional survey conducted between October 2019 and March 2020, nested within the PISCIS cohort of people living with HIV in Catalonia and the Balearic Islands, Spain. We used the 12-item short-form survey (SF-12), divided into a physical component summary (PCS) and a mental component summary (MCS), to evaluate HRQoL. We used the least absolute shrinkage and selection operator for variable selection and used multivariable regression models to identify predictors. RESULTS: Of the 1060 people living with HIV (78.6% males) who participated in the study, 209 (19.7%) were aged ≥60 years. When comparing older people living with HIV (≥60 years) and their younger counterparts, older people exhibited a worse PCS (median 51.3 [interquartile range {IQR} 46.0-58.1] vs. 46.43 [IQR 42.5-52.7], p < 0.001) but a similar MCS (median 56.0 [IQR 49.34-64.7] vs. 57.0 [IQR 48.9-66.3], p = 0.476). In the multivariable analysis, cognitive function correlated with a PCS (ß correlation factor [ß] -0.18, p = 0.014), and depressive symptoms and satisfaction with social role correlated with an MCS (ß 0.61 and ß -0.97, respectively, p < 0.001) in people living with HIV aged ≥60 years. CONCLUSION: Depressive symptoms, poor cognitive function, and lower satisfaction with social roles predict poorer HRQoL in older people living with HIV. These factors need to be considered when designing targeted interventions.

Who is lost to follow-up in HIV care? Assessment of care retention over time and the impact of COVID-19. Longitudinal analysis of the PISCIS cohort.

INTRODUCTION: People living with HIV who are lost to follow-up have a greater risk of health deterioration, mortality, and community transmission. OBJECTIVE: Our aim was to analyse both how rates of loss to follow-up (LTFU) changed between 2006 and 2020 and how the COVID-19 pandemic affected these rates in the PISCIS cohort study of Catalonia and the Balearic Islands. METHODS: We analysed socio-demographic and clinical characteristics of LTFU yearly and with adjusted odds ratios to assess the impact of these determinants on LTFU in 2020 (the year of COVID-19). We used latent class analysis to categorize classes of LTFU based on their socio-demographic and clinical characteristics at each year. RESULTS: In total, 16.7% of the cohort were lost to follow-up at any time in the 15 years (n = 19 417). Of people living with HIV who were receiving follow-up, 81.5% were male and 19.5% were female; of those who were lost to follow-up, 79.6% and 20.4% were male and female, respectively (p < 0.001). Although rates of LTFU increased during COVID-19 (1.11% vs. 0.86%, p = 0.024), socio-demographic and clinical factors were similar. Eight classes of people living with HIV who were lost to follow-up were identified: six for men and two for women. Classes of men (n = 3) differed in terms of their country of birth, viral load (VL), and antiretroviral therapy (ART); classes of people who inject drugs (n = 2) differed in terms of VL, AIDS diagnosis, and ART. Changes in rates of LTFU included higher CD4 cell count and undetectable VL. CONCLUSIONS: The socio-demographic and clinical characteristics of people living with HIV changed over time. Although the circumstances of the COVID-19 pandemic increased the rates of LTFU, the characteristics of these people were similar. Epidemiological trends among people who were lost to follow-up can be used to prevent new losses of care and to reduce barriers to achieve Joint United Nations Programme on HIV/AIDS 95-95-95 targets.

Syndemic conditions and quality of life in the PISCIS Cohort of people living with HIV in Catalonia and the Balearic Islands: a cross sectional study.

BACKGROUND: People living with HIV (PLWH) face structural and psychosocial factors that affect health-related quality of life (HRQoL). We aimed to evaluate how syndemic conditions affected HRQoL in PLWH. METHODS: A cross-sectional survey was conducted among 861 PLWH, to determine whether syndemic conditions (monthly income; sexual satisfaction; depressive symptoms; social role satisfaction; social isolation; cognitive function; nicotine dependence; perception of stigma) have an effect on HRQoL. A linear regression model and measures of Additive Interaction (AI) were used to determine the effects of syndemic conditions on HRQoL, controlling for other risk factors. RESULTS: Overall, the most frequently observed were stigma perception (56.9%), poor cognitive function (50.6%) and the perception of social isolation (51.6%). The presence of depressive symptoms was the risk factor most associated with worse Physical Health (PH) (B 3.93, 2.71-5.15) and Mental Health (MH) (B 5.08, 3.81-6.34) in linear regression model. Specifically, an interaction was observed between poor cognitive function and poor satisfaction with social role on worse PH and MH (AI 2.08, 0.14-4.02; AI 2.69, 0.15-5.22, respectively); and low income and perception of stigma (AI 2.98, 0.26-5.71), low income and perception of social isolation (AI 2.79, 0.27-5.32), and low income and poor satisfaction with social role (AI 3.45, 0.99-5.91) on MH. CONCLUSION: These findings provide evidence that syndemic factors impact HRQoL. HIV prevention programs should screen and address co-occurring health problems to improve patient-centered health care and outcomes.

Mortality and immunovirological outcomes in patients with advanced HIV disease on their first antiretroviral treatment: differential impact of antiretroviral regimens.

OBJECTIVES: To assess the clinical and immunovirological outcomes among naive patients with advanced HIV presentation starting an antiretroviral regimen in real-life settings. METHODS: This was a multicentre, prospective cohort study. We included all treatment-naive adults with advanced HIV disease (CD4+ T cell count < 200 cells/mm3or presence of an AIDS-defining illness) who started therapy between 2010 and 2020. The main outcomes were mortality, virological effectiveness (percentage of patients with viral load of ≤50 copies/mL) and immune restoration (percentage of patients with CD4+ T cell count above 350 cells/mm3). Competing risk analysis and Cox proportional models were performed. A propensity score-matching procedure was applied to assess the impact of the antiretroviral regimen. RESULTS: We included 1594 patients with advanced HIV disease [median CD4+T cell count of 81 cells/mm3and 371 (23.3%) with AIDS-defining illness] and with a median follow-up of 4.44 years. The most common ART used was an integrase strand transfer inhibitor (InSTI) regimen (46.9%), followed by PI (35.7%) and NNRTI (17.4%), with adjusted mortality rates at 3 years of 3.1% (95% CI 1.8%-4.3%), 4.7% (95% CI 2.2%-7.1%) and 7.6% (95% CI 5.4%-9.7%) (P = 0.001), respectively. Factors associated with increased mortality included older age and history of injection drug use, whilst treatment with an InSTI regimen was a protective factor [HR 0.5 (95% CI 0.3-0.9)]. A sensitivity analysis with propensity score procedure confirms these results. Patients who started an InSTI achieved viral suppression and CD4+ T cell count above 350 cells/mm3significantly earlier. CONCLUSIONS: In this large real-life prospective cohort study, a significant lower mortality, earlier viral suppression and earlier immune reconstitution were observed among patients with advanced HIV disease treated with InSTIs.

Impact of tenofovir on SARS-CoV-2 infection and severe outcomes among people living with HIV: a propensity score-matched study.

BACKGROUND: Reports on the impact of some antiretrovirals against SARS-CoV-2 infection and disease severity are conflicting. OBJECTIVES: We evaluated the effect of tenofovir as either tenofovir alafenamide/emtricitabine (TAF/FTC) or tenofovir disoproxil fumarate/emtricitabine (TDF/FTC) against SARS-CoV-2 infection and associated clinical outcomes among people living with HIV (PLWH). METHODS: We conducted a propensity score-matched analysis in the prospective PISCIS cohort of PLWH (n = 14 978) in Catalonia, Spain. We used adjusted Cox regression models to assess the association between tenofovir and SARS-CoV-2 outcomes. RESULTS: After propensity score-matching, SARS-CoV-2 diagnosis rates were similar in TAF/FTC versus ABC/3TC recipients (11.6% versus 12.5%, P = 0.256); lower among TDF/FTC versus ABC/3TC recipients (9.6% versus 12.8%, P = 0.021); and lower among TDF/FTC versus TAF/FTC recipients (9.6% versus 12.1%, P = 0.012). In well-adjusted logistic regression models, TAF/FTC was no longer associated with reduced SARS-CoV-2 diagnosis [adjusted odds ratio (aOR) 0.90; 95% confidence interval (CI), 0.78-1.04] or hospitalization (aOR 0.93; 95% CI, 0.60-1.43). When compared with ABC/3TC, TDF/FTC was not associated with reduced SARS-CoV-2 diagnosis (aOR 0.79; 95% CI, 0.60-1.04) or hospitalization (aOR 0.51; 95% CI, 0.15-1.70). TDF/FTC was not associated with reduced SARS-CoV-2 diagnosis (aOR 0.79; 95% CI, 0.60-1.04) or associated hospitalization (aOR 0.33; 95% CI, 0.10-1.07) compared with TAF/FTC. CONCLUSIONS: TAF/FTC or TDF/FTC were not associated with reduced SARS-CoV-2 diagnosis rates or associated hospitalizations among PLWH. TDF/FTC users had baseline characteristics intrinsically associated with more benign SARS-CoV-2 infection outcomes. Tenofovir exposure should not modify any preventive or therapeutic SARS-CoV-2 infection management.

Strategies to reengage patients lost to follow up in HIV care in high income countries, a scoping review.

BACKGROUND: Despite remarkable achievements in antiretroviral therapy (ART), losses to follow-up (LTFU) might prevent the long-term success of HIV treatment and might delay the achievement of the 90-90-90 objectives. This scoping review is aimed at the description and analysis of the strategies used in high-income countries to reengage LTFU in HIV care, their implementation and impact. METHODS: A scoping review was done following Arksey & O'Malley's methodological framework and recommendations from Joanna Briggs Institute. Peer reviewed articles were searched for in Pubmed, Scopus and Web of Science; and grey literature was searched for in Google and other sources of information. Documents were charted according to the information presented on LTFU, the reengagement procedures used in HIV units in high-income countries, published during the last 15 years. In addition, bibliographies of chosen articles were reviewed for additional articles. RESULTS: Twenty-eight documents were finally included, over 80% of them published in the United States later than 2015. Database searches, phone calls and/or mail contacts were the most common strategies used to locate and track LTFU, while motivational interviews and strengths-based techniques were used most often during reengagement visits. Outcomes like tracing activities efficacy, rates of reengagement and viral load reduction were reported as outcome measures. CONCLUSIONS: This review shows a recent and growing trend in developing and implementing patient reengagement strategies in HIV care. However, most of these strategies have been implemented in the United States and little information is available for other high-income countries. The procedures used to trace and contact LTFU are similar across reviewed studies, but their impact and sustainability are widely different depending on the country studied.

Disparities in Coronavirus Disease 2019 Clinical Outcomes and Vaccination Coverage Among Migrants With Human Immunodeficiency Virus in the PISCIS Cohort: A Population-Based Propensity Score-Matched Analysis.

Background: Coronavirus disease 2019 (COVID-19) disproportionately affects migrants and ethnic minorities, including those with human immunodeficiency virus (HIV). Comprehensive studies are needed to understand the impact and risk factors. Methods: Using data from the PISCIS cohort of people with HIV (PWH) in Catalonia, Spain, we investigated COVID-19 outcomes and vaccination coverage. Among 10 640 PWH we compared migrants and non-migrants assessing rates of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing, diagnosis, and associated clinical outcomes through propensity score matching and multivariable Cox regression. Results: The cohort (mean age, 43 years; 83.5% male) included 57.4% (3053) Latin American migrants. Migrants with HIV (MWH) had fewer SARS-CoV-2 tests (67.8% vs 72.1%, P < .0001) but similar COVID-19 diagnoses (29.2% vs 29.4%, P = .847) compared to Spanish natives. Migrants had lower complete vaccination (78.9% vs 85.1%, P < .0001) and booster doses (63.0% vs 65.5%, P = .027). COVID-19 hospitalizations (8.1% vs 5.1%, P < .0001) and intensive care unit (ICU) admissions (2.9% vs 1.2%, P < .0001) were higher among migrants, with similar hospitalization duration (5.5 vs 4.0 days, P = .098) and mortality (3 [0.2%] vs 6 [0.4%], P = .510). Age ≥40 years, CD4 counts <200 cells/µL, ≥2 comorbidities, and incomplete/nonreception of the SARS-CoV-2 vaccine increased the risk of severe COVID-19 among migrants. Conclusions: MWH had lower rates of SARS-CoV-2 testing and vaccination coverage, although the rates of COVID-19 diagnosis were similar between migrants and non-migrants. Rates of COVID-19-associated hospitalizations and ICU admissions were higher among migrants in comparison with non-migrants, with similar hospitalization duration and mortality. These findings can inform policies to address disparities in future pandemic responses for MWH.

The impact of the COVID-19 pandemic on healthcare services utilization among people living with HIV in Catalonia, Spain: A population-based cohort study.

BACKGROUND: The COVID-19 pandemic disrupted healthcare services usage. We estimated the impact of the COVID-19 pandemic on healthcare services utilization among people living with HIV (PLWH) in Catalonia, Spain. METHODS: We accessed public healthcare usage in HIV units, primary care, hospitals, and emergency departments among 17,738 PLWH in the PISCIS cohort from January 1, 2017, to December 31, 2020. We performed an interrupted time series analysis using the autoregressive integrated moving average to estimate the effect of COVID-19 on medical visits and HIV monitoring among PLWH. RESULTS: A non-significant decrease of 17.1% (95% CI: [-29.4, 0.4]) in overall medical visits was observed during the lockdown, followed by a steady resumption until the end of 2020. Three health facilities presented statistically significant declines in visits during the lockdown: HIV units (-44.8% [-56.7, -23.6]), hospitals (-40.4% [-52.8, -18.1]), and emergency departments (-36.9% [-47.0, -21.9]); thereafter, the visits have begun to increase steadily but not to previous levels as of December 2020. In contrast, primary care visits remained unchanged during the lockdown by 1.9% (95% CI: -13.5, 23.9). CD4 cell (54.2% [95% CI: -64.4, -36.0]) and HIV RNA viral load (53.1% [95% CI: -62.9, -36.1]) laboratory monitoring reduced significantly during the lockdown. CONCLUSION: COVID-19 lockdowns significantly disrupted in-person healthcare services usage among PLWH. The reduction in healthcare utilization however did not affect primary care services. Despite services gradually rebounding to pre-pandemic levels, it is imperative to effectively prepare for future pandemics and implement measures to ensure continuous provision of care to PLWH during pandemic lockdowns.

Developing and validating a clinical risk score to predict losses in the PISCIS cohort of people with HIV.

BACKGROUND: People lost to follow-up (LTFU) from HIV care have an increased risk of worse health. The objective of this study is to create and validate a risk score to predict LTFU among PLWH in Catalonia and the Balearic Islands. METHODS: 6661 PLWH were included. LTFU were those without contact with HIV care for 12 months or more. Logistic regression models were used to assess the role of independent factors on LTFU. The validation included a 10-fold iteration to predict the performance of the regression model and the Area under the ROC Curve (AUC). Regression coefficients were rounded and summed to construct the score. RESULTS: Determinants of LTFU included being younger than 34 years (OR: 1.80, CI, 1.44-2.23), not having been born in Spain (OR: 1.32, 1.11-1.58), men who inject drugs (OR: 2.10, 1.38-3.19), having a detectable viral load (OR: 3.14, 2.47-3.99), and ≤2.5 years since HIV diagnosis (OR: 3.84, 3.10-4.75). The validation of determinants resulted in a mean AUC of 0.69 and the risk-score revealed that 28.8% had a medium and 3.4% a high risk of LTFU respectively. CONCLUSIONS: Findings can be used to prevent LTFU in HIV care.

Major cardiovascular events after COVID-19 in people with HIV.

OBJECTIVES: To assess the effect of COVID-19 on the postacute risk of cardiovascular events (CVEs) among people with HIV (PWH). METHODS: Population-based matched cohort, including all PWH ≥16 years in the Catalan PISCIS HIV cohort. We estimated the incidence rate of the first CVE after COVID-19, analysed it a composite outcome (2020-2022). We adjusted for baseline differences using inverse probability weighting and used competing risk analysis. RESULTS: We included 4199 PWH with and 14 004 PWH without COVID-19. The median follow-up was 243 days (interquartile range [IQR]: 93-455), 82% (14 941/18 203) were men, with a median age of 47 years. Overall, 211 PWH with COVID-19 and 621 without developed CVE, with an incidence rate of 70.2 and 56.8/1000 person-years, respectively. During COVID-19 infection, 7.6% (320/4199) required hospitalization and 0.6% (25/4199) intensive care unit admission, 97% (4079/4199) had CD4+T-cell ≥200 cells/µL, 90% (3791/4199) had HIV-RNA<50 copies/mL and 11.8% (496/4199) had previous CVE at baseline. The cumulative CVE incidence was higher among PWH after COVID-19 compared with PWH without COVID-19 during the first year (log-rank p=0.011). The multivariable analysis identified significantly increased CVE risk with age, heterosexual men, previous cardiovascular disease (CVD), and chronic kidney or liver disease. COVID-19 was associated with increased subsequent risk of CVE (adjusted hazard ratio 1.30 [95% CI, 1.09-1.55]), also when only including individuals without previous CVD (1.60 [95% CI, 1.11-2.29]) or nonhospitalized patients (1.34 [95% CI, 1.11-1.62]). DISCUSSION: COVID-19 was associated with a 30% increased risk of major CVE in PWH during the subsequent year, suggesting that COVID-19 should be considered an additional CVD risk in PWH in the short term.

Evolving AIDS- and non-AIDS Mortality and Predictors in the PISCIS Cohort of People Living With HIV in Catalonia and the Balearic Islands (Spain), 1998-2020.

Background: Effective antiretroviral therapy (ART) has substantially reduced acquired immunodeficiency syndrome (AIDS)-related deaths, shifting the focus to non-AIDS conditions in people living with human immunodeficiency virus (HIV) (PLWH). We examined mortality trends and predictors of AIDS- and non-AIDS mortality in the Population HIV Cohort from Catalonia and Balearic Islands (PISCIS) cohort of PLWH from 1998 to 2020. Methods: We used a modified Coding Causes of Death in HIV protocol, which has been widely adopted by various HIV cohorts to classify mortality causes. We applied standardized mortality rates (SMR) to compare with the general population and used competing risks models to determine AIDS-related and non-AIDS-related mortality predictors. Results: Among 30 394 PLWH (81.5% male, median age at death 47.3), crude mortality was 14.2 per 1000 person-years. All-cause standardized mortality rates dropped from 9.6 (95% confidence interval [CI], 8.45-10.90) in 1998 through 2003 to 3.33 (95% CI, 3.14-3.53) in 2015 through 2020, P for trend = .0001. Major causes were AIDS, non-AIDS cancers, cardiovascular disease, AIDS-defining cancers, viral hepatitis, and nonhepatitis liver disease. Predictors for AIDS-related mortality included being aged ≥40 years, not being a man who have sex with men, history of AIDS-defining illnesses, CD4 < 200 cells/µL, ≥2 comorbidities, and nonreceipt of ART. Non-AIDS mortality increased with age, injection drug use, heterosexual men, socioeconomic deprivation, CD4 200 to 349 cells/µL, nonreceipt of ART, and comorbidities, but migrants had lower risk (adjusted hazard risk, 0.69 [95% CI, .57-.83]). Conclusions: Mortality rates among PLWH have significantly decreased over the past 2 decades, with a notable shift toward non-AIDS-related causes. Continuous monitoring and effective management of these non-AIDS conditions are essential to enhance overall health outcomes.

Prevalence, risk factors and the impact of tenofovir treatment in SARS-CoV-2 infection and COVID-19 disease among people living with HIV. A cross-sectional population-based study.

The prevalence and risk factors of SARS-CoV-2 infection among unvaccinated people living with HIV (PWH) are not well understood, and the protective role of tenofovir remains controversial. This study aimed to assess the SARS-CoV-2 prevalence and associated risk factors among unvaccinated PWH, and to evaluate the impact of tenofovir. We conducted as a cross-sectional study between November 2020 and May 2021. Plasma samples from 4,400 of 5,476 PWH were tested for total antibodies, IgG, IgM, and IgA. Among the participants (median age 48 years, 84% male), 92% had undetectable HIV viral loads and 5% had syphilis. The prevalence of SARS-CoV-2 infection was 18% (95% CI 17-19), with 1,180 individuals showing antibodies (IgG 13%, IgA 10%, IgM 11%). Of those seropositive for SARS-CoV-2, 67.5% were asymptomatic, 29% had mild disease, and 3.5% had severe/critical conditions. Risk factors included younger age, being female, men who have sex with men (MSM) status, non-European origin, and a history of syphilis. Neither antiretrovirals nor tenofovir provided protection against SARS-CoV-2 infection or COVID-19 disease. Ongoing surveillance and tailored interventions are crucial for at-risk PWH amid evolving SARS-CoV-2 variants.

Civil Engineering and Malaria Risk: A Descriptive Study in a Rural Area of Cubal, Angola.

(1) Background: Angola is among the high-burden countries with malaria cases globally. After 2013, we suspected an increase in the number of malaria cases in Cubal (Angola), previously in decline. Our objective was to evaluate the incidence rate in Cubal, overall and by neighborhood, for 2014, 2015, and 2016. (2) Methods: A retrospective, observational study was performed in Cubal (Angola) from January 2014 to December 2016, including all patients with a microbiologically confirmed diagnosis, treated at Cubal's Hospitals for this period of time. The principal variables calculated were the incidence rates of 2014, 2015, and 2016 in Cubal (overall and by neighborhood). (3) Results: There were 3249 malaria cases. The incidence rates were 2.27, 10.73, and 12.40 cases per 1000 inhabitants in 2014, 2015, and 2016, respectively. In the neighborhood, Hamavoko-Kasseke, there was a 10.73-fold increase in incidence during this period. Additionally, Hamavoko-Kasseke presents an anomalous distribution of malaria cases. (4) Conclusions: We observed an increase in the incidence of malaria in Cubal during the three-year study period. The case distribution was highly heterogeneous with hyperendemic areas, and we found a chronobiological association between the construction of a civil engineering project. This information could be useful for deciding which malaria control strategies must be implemented in this area.

Determinants of Depressive Symptoms in People Living with HIV: Findings from a Population-Based Study with a Gender Perspective.

Depressive symptoms are common among people living with HIV (PLWH). The aim of this study was to identify the determinants of depressive symptoms in PLWH in Spain. A total of 1060 PLWH participated in this cross-sectional study and completed the Patient Health Questionnaire-9. The odds ratios for the presence of depressive symptoms were analyzed in a multivariable logistic regression model, including sociodemographic data, comorbidities, health-related behaviors, and social-environment-related variables. We found an overall prevalence of depressive symptoms of 21.42%; by subgroup, namely men, women, and transgender persons, prevalence was 18.13%, 32.81%, and 37.14%, respectively. Moreover, social isolation (OR = 1.05 [CI, 1.02-1.08]) and poor physical and mental quality of life (OR = 1.06 [CI, 1.02-1.09] and OR = 1.13 [CI, 1.09-1.17], respectively) were associated with depressive symptoms. As protective factors, we identified serodisclosure to more people (vs. none; OR = 0.39 [CI, 0.17-0.87]), satisfaction with social roles (OR = 0.86 [CI, 0.79-0.94]), better cognitive function (OR = 0.92 [CI, 0.89-0.95]), and sexualized drug use once in a lifetime (OR = 0.52 [CI, 0.29-0.93]). This study showed a high prevalence of depressive symptoms in PLWH, especially among women and transgender people. The association between psychosocial variables and depressive symptoms highlights the multidimensionality of the problem and identifies areas for intervention. This study found that the management of mental health issues is an area that needs to be improved and tailored to specific groups, with the aim of enhancing the well-being of PLWH.

Cardiovascular events in delayed presentation of HIV: the prospective PISCIS cohort study.

Objectives: People with HIV (PWH) have a higher cardiovascular risk than the general population. It remains unclear, however, whether the risk of cardiovascular disease (CVD) is higher in late HIV presenters (LP; CD4 ≤ 350 cells/µL at HIV diagnosis) compared to PWH diagnosed early. We aimed to assess the rates of incident cardiovascular events (CVEs) following ART initiation among LP compared to non-LP. Methods: From the prospective, multicentre PISCIS cohort, we included all adult people with HIV (PWH) initiating antiretroviral therapy (ART) between 2005 and 2019 without prior CVE. Additional data were extracted from public health registries. The primary outcome was the incidence of first CVE (ischemic heart disease, congestive heart failure, cerebrovascular, or peripheral vascular disease). The secondary outcome was all-cause mortality after the first CVE. We used Poisson regression. Results: We included 3,317 PWH [26 589.1 person/years (PY)]: 1761 LP and 1556 non-LP. Overall, 163 (4.9%) experienced a CVE [IR 6.1/1000PY (95%CI: 5.3-7.1)]: 105 (6.0%) LP vs. 58 (3.7%) non-LP. No differences were observed in the multivariate analysis adjusting for age, transmission mode, comorbidities, and calendar time, regardless of CD4 at ART initiation [aIRR 0.92 (0.62-1.36) and 0.84 (0.56-1.26) in LP with CD4 count <200 and 200- ≤ 350 cells/µL, respectively, compared to non-LP]. Overall mortality was 8.5% in LP versus 2.3% in non-LP (p < 0.001). Mortality after the CVE was 31/163 (19.0%), with no differences between groups [aMRR 1.24 (0.45-3.44)]. Women vs. MSM and individuals with chronic lung and liver disease experienced particularly high mortality after the CVE [aMRR 5.89 (1.35-25.60), 5.06 (1.61-15.91), and 3.49 (1.08-11.26), respectively]. Sensitivity analyses including only PWH surviving the first 2 years yielded similar results. Conclusion: CVD remains a common cause of morbidity and mortality among PWH. LP without prior CVD did not exhibit an increased long-term risk of CVE compared with non-LP. Identifying traditional cardiovascular risk factors is essential for CVD risk reduction in this population.

Mpox: Clinical Outcomes and Impact of Vaccination in People with and without HIV: A Population-Wide Study.

We investigated differences in mpox clinical outcomes in people with HIV (PWH) and without HIV (PWoH) and the impact of vaccination in Catalonia, Spain. We used surveillance data and the PISCIS HIV cohort. We included all confirmed mpox cases (May-December 2022). Of 2122 mpox cases, the majority had mild disease, 56% were Spanish, and 24% were from Latin America. A total of 40% were PWH, with a median CD4+T-cell of 715 cells/µL; 83% had HIV-RNA < 50 copies/mL; and 1.8% CD4+T-cell < 200 cells/µL. PWH had no increased risk for complications, except those with CD4+T-cell < 200 cells/µL. PWH with CD4+T-cell < 200 cells/µL were more likely to be from Latin America, had more generalized exanthema, and required hospitalization more frequently (p = 0.001). Diagnosis of other sexually transmitted infections (STIs) was common, both at mpox diagnosis (17%) and two years before (43%). Dose-sparing smallpox intradermal vaccination was accompanied by a sharp decrease in mpox incidence in both populations (p < 0.0001). In conclusion, unless immunosuppressed, PWH were not at increased risk of severe disease or hospitalization. Mpox is a marker of high-risk sexual behavior and was associated with high HIV and STI rates, supporting the need for screening in all mpox cases. Ethnicity disparities demonstrate the need for interventions to ensure equitable healthcare access. Dose-sparing smallpox vaccination retained effectiveness.

Comparative Analysis of Primary and Monovalent Booster SARS-CoV-2 Vaccination Coverage in Adults with and without HIV in Catalonia, Spain.

People with HIV (PWH) may be more susceptible to SARS-CoV-2 infection and worse clinical outcomes. We investigated the disparity in SARS-CoV-2 vaccination coverage between PWH and those without HIV (PWoH) in Catalonia, Spain, assessing primary and monovalent booster vaccination coverage from December 2021 to July 2022. The vaccines administered were BNT162, ChAdOx1-S, mRNA-127, and Ad26.COV2.S. Using a 1:10 ratio of PWH to PWoH based on sex, age, and socioeconomic deprivation, the analysis included 201,630 individuals (183,300 PWoH and 18,330 PWH). Despite a higher prevalence of comorbidities, PWH exhibited lower rates of complete primary vaccination (78.2% vs. 81.8%, p < 0.001) but surpassed PWoH in booster coverage (68.5% vs. 63.1%, p < 0.001). Notably, complete vaccination rates were lower among PWH with CD4 <200 cells/µL, detectable HIV viremia, and migrants compared to PWoH (p < 0.001, all). However, PWH with CD4 < 200 cells/µL received more boosters (p < 0.001). In multivariable logistic regression analysis of the overall population, a prior SARS-CoV-2 diagnosis, HIV status, migrants, and mild-to-severe socioeconomic deprivation were associated with lower primary vaccination coverage, reflecting barriers to healthcare and vaccine access. However, booster vaccination was higher among PWH. Targeted interventions are needed to improve vaccine coverage and address hesitancy in vulnerable populations.

Determinants of long-term survival in late HIV presenters: The prospective PISCIS cohort study.

Background: Late HIV diagnosis (i.e CD4≤350 cells/µL) is associated with poorer outcomes. However, determinants of long-term mortality and factors influencing immune recovery within the first years after antiretroviral treatment (ART) initiation are poorly defined. Methods: From PISCIS cohort, we included all HIV-positive adults, two-year survivors after initiating ART between 2005-2019. The primary outcome was all-cause mortality according to the two-year CD4 count. We used Poisson regression. The secondary outcome was incomplete immune recovery (i.e., two-year CD4<500 cells/µL). We used logistic regression and propensity score matching. Findings: We included 2,719 participants (16593·1 person-years): 1441 (53%) late presenters (LP) and 1278 non-LP (1145 non-LP with two-year CD4 count >500 cells/µL, reference population). Overall, 113 patients (4·2%) died. Mortality was higher among LP with two-year CD4 count 200-500 cells/µL (aMRR 1·95[95%CI:1·06-3·61]) or <200 cells/µL (aMRR 4·59[2·25-9·37]).Conversely, no differences were observed in participants with two-year CD4 counts >500 cells/µL, regardless of being initially LP or non-LP (aMRR 1·05[0·50-2·21]). Mortality rates within each two-year CD4 strata were not affected by the initial CD4 count at ART initiation (test-interaction, p = 0·48). The stronger factor influencing immune recovery was the CD4 count at ART initiation. First-line integrase-inhibitor-(INSTI)-based regimens were associated with reduced mortality compared to other regimens (aMRR 0·54[0·31-0·93]) and reduced risk of incomplete immune recovery in LP (aOR 0·70[0·52-0·95]). Interpretation: Two-year immune recovery is a good early predictor of long-term mortality in LP after surviving the first high-risk 2 years. Nearly half experienced a favorable immune recovery with a life expectancy similar to non-LP. INSTI-based regimens were associated with higher rates of successful immune recovery and better survival compared to non-INSTI regimens.
