Determinants of HIV late presentation among men who have sex with men in Portugal (2014-2019): who's being left behind?

Introduction: HIV late presentation (LP) remains excessive in Europe. We aimed to analyze the factors associated with late presentation in the MSM population newly diagnosed with HIV in Portugal between 2014 and 2019. Methods: We included 391 newly HIV-1 diagnosed Men who have Sex with Men (MSM), from the BESTHOPE project, in 17 countrywide Portuguese hospitals. The data included clinical and socio-behavioral questionnaires and the viral genomic sequence obtained in the drug resistance test before starting antiretrovirals (ARVs). HIV-1 subtypes and epidemiological surveillance mutations were determined using different bioinformatics tools. Logistic regression was used to estimate the association between predictor variables and late presentation (LP). Results: The median age was 31 years, 51% had a current income between 501-1,000 euros, 28% were migrants. 21% had never been tested for HIV before diagnosis, with 42.3% of MSM presenting LP. 60% were infected with subtype B strains. In the multivariate regression, increased age at diagnosis, higher income, lower frequency of screening, STI ever diagnosed and higher viral load were associated with LP. Conclusion: Our study suggests that specific subgroups of the MSM population, such older MSM, with higher income and lower HIV testing frequency, are not being targeted by community and clinical screening services. Overall, targeted public health measures should be strengthened toward these subgroups, through strengthened primary care testing, expanded access to PrEP, information and promotion of HIV self-testing and more inclusive and accessible health services.

Real-World Characterization of the Portuguese Population Living with HIV who Initiated Raltegravir Based-Regimens: The REALITY Study.

INTRODUCTION: Although raltegravir has been available since 2007, data are lacking on the Portuguese population living with HIV who initiated this antiretroviral therapy. Hence, this study aimed to characterize the patients who initiated raltegravir-based regimens between January 2015 and December 2017, on sociodemographics, clinical features, and treatment satisfaction. MATERIAL AND METHODS: Observational, retrospective, multicentre study conducted at 11 reference sites. Sociodemographic and clinical data were collected retrospectively from hospital medical records. For participants continuing raltegravir at study inclusion, the HIV Treatment Satisfaction Questionnaire was administered to assess satisfaction with raltegravir-based therapy. Descriptive statistics were performed. Treatment-naïve and treatment-experienced subgroups were compared for demographic and clinical variables. RESULTS: A total of 302 patients were included; mostly men (69.5%) with a mean age of 49 years old. Approximately half of the patients had at least one non-AIDS-related comorbidity at baseline (53.3%), such as hypercholesterolemia, arterial hypertension, diabetes mellitus, and depression. Moreover, 52.3% were treatment-experienced patients with up to two treatments prior to raltegravir. Across the study time points, there was a reduction in the viral load and improvement in CD4 counts in both the treatment-naïve and treatment-experienced subgroups. Continuing users of raltegravir reported high treatment satisfaction (55.4 ± 7.2 points). CONCLUSION: Raltegravir-based regimens seem like a valid therapeutic option in heterogeneous populations of HIV-infected patients, in patients with previous ART experience and as part of first-line therapeutic options alongside with the latest generation of drugs from its class.

Introdução: Apesar de o raltegravir estar disponível desde 2007, os dados na população portuguesa com VIH que iniciou esta terapêutica antirretroviral são escassos. Deste modo, este estudo teve por objetivo caracterizar os doentes que iniciaram um regime terapêutico baseado em raltegravir entre janeiro de 2015 e dezembro de 2017, relativamente a dados sociodemográficos, características clínicas e satisfação com o tratamento. Material e Métodos: Estudo observacional, retrospetivo, multicêntrico conduzido em 11 centros de referência. Os dados sociodemográficos e clínicos foram recolhidos retrospetivamente nos processos clínicos. Os participantes que continuaram o regime com raltegravir após a inclusão no estudo preencheram o HIV Treatment Satisfaction Questionnaire para avaliar a satisfação com a terapêutica. Foram efetuadas análises de estatística descritiva e comparações para as variáveis sociodemográficas e clínicas nos subgrupos de doentes naïve de tratamento e de doentes com experiência terapêutica. Resultados: Foram incluídos 302 doentes, maioritariamente do sexo masculino (69,5%) com idade média de 49 anos. Aproximadamente metade dos doentes tinha pelo menos uma comorbilidade não relacionada com SIDA no início do estudo (53,3%), tais como hipercolesterolemia, hipertensão arterial, diabetes mellitus ou depressão. Adicionalmente, 52,3% eram doentes com experiência terapêutica com até dois tratamentos anteriores ao raltegravir. Ao longo do estudo verificou-se uma redução na carga viral e uma melhoria nas contagens de CD4 em ambos os subgrupos de doentes (doentes naïve de tratamento e doentes com experiência terapêutica). Os doentes com uso continuado de raltegravir reportaram uma elevada satisfação com o tratamento (55,4 ± 7,2 pontos). Conclusão: Os regimes terapêuticos baseados em raltegravir parecem ser uma opção terapêutica válida em populações heterogéneas de doentes infetados com VIH, em doentes com experiência em ART e como tratamento de primeira linha, em paralelo com outras terapêuticas de última geração.

Non-AIDS-related comorbidities in people living with HIV-1 aged 50 years and older: The AGING POSITIVE study.

OBJECTIVE: To characterize the profile of non-AIDS-related comorbidities (NARC) in the older HIV-1-infected population and to explore the factors associated with multiple NARC. METHODS: This was a multicentre, cross-sectional study including HIV-1-infected patients aged ≥50 years, who were virologically suppressed and had been on a stable antiretroviral therapy (ART) regimen for at least 6 months. A multiple regression model explored the association between demographic and clinical variables and the number of NARC. RESULTS: Overall, 401 patients were enrolled. The mean age of the patients was 59.3 years and 72.6% were male. The mean duration of HIV-1 infection was 12.0 years and the median exposure to ART was 10.0 years. The mean number of NARC was 2.1, and 34.7% of patients had three or more NARC. Hypercholesterolemia was the most frequent NARC (60.8%), followed by arterial hypertension (39.7%) and chronic depression/anxiety (23.9%). Arterial hypertension and diabetes mellitus were the most frequently treated NARC (95.6% and 92.6% of cases, respectively). The linear regression analysis showed a positive relationship between age and NARC (B=0.032, 95% confidence interval 0.015-0.049; p=0.0003) and between the duration of HIV-1 infection and NARC (B=0.039, 95% confidence interval 0.017-0.059; p=0.0005). CONCLUSIONS: A high prevalence of NARC was found, the most common being metabolic, cardiovascular, and psychological conditions. NARC rates were similar to those reported for the general population, suggesting a larger societal problem beyond HIV infection. A multidisciplinary approach is essential to reduce the burden of complex multi-morbid conditions in the HIV-1-infected population.
