RESUMO
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 countâ<â200â 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 ≤50â copies/mL) and immune restoration (percentage of patients with CD4+ T cell count above 350â 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 81â cells/mm3and 371 (23.3%) with AIDS-defining illness] and with a median follow-up of 4.44â 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 3â 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%) (Pâ=â0.001), 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 350â 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.

BACKGROUND: People with HIV have a substantially higher risk of anal cancer than the general population. We aimed to identify risk factors associated with the development of anal cancer among people with HIV to implement more effective and targeted screening strategies. METHODS: We conducted a multicentre retrospective cohort study in 16 hospitals across Catalonia and the Balearic Islands, Spain, between Jan 1, 1998, and Dec 31, 2022. Treatment-naive people with HIV nested in the PISCIS cohort aged 16 years and older with biopsy-proven squamous cell carcinoma of the anus or anal canal were eligible for inclusion. Data were retrieved from every hospital registry and were centrally validated in the PISCIS cohort and the Public Data Analysis for Health Research and Innovation Program. The primary outcome was the incidence rate (IR) of histologically confirmed anal cancer. We used Poisson regression to examine the association between the following risk factors and incidence of anal cancer: age, mode of HIV transmission, nadir CD4 cell count, and time period of HIV diagnosis. FINDINGS: Among 14â238 people with HIV, 107 (0·8%) developed anal cancer, with an overall IR of 72·5 cases per 100â000 person-years (95% CI 59·4-87·6) and median follow-up of 9·5 years (IQR 4·4-15·7). Of these patients with anal cancer, 37 (34·6%) died, of which 24 (64·9%) deaths were related to anal cancer. Incidence was highest among people with HIV with historical nadir CD4 counts of less than 200 cells per µL (IR 105·0 person-years, 95% CI 82·0-132·5) and lowest among those with counts of more than 350 cells per µL (2·9 person-years, 0·1-16·0). Among men who have sex with men (MSM), the IR was 211·5 person-years (95% CI 151·1-211·7) among those with a CD4 count of less than 200 cells per µL, 37·6 person-years (16·2-74·1) among those with a count of 200-350 cells per µL, and 4·8 person-years (0·1-26·9) among those with a count of more than 350 cells per µL. Among people with HIV younger than 30 years, there were no cases of anal cancer among women or men who do not have sex with men, and one case among MSM with a nadir CD4 count of more than 350 cells per µL (IR 4·8 person-years, 95% CI 0·1-26·9). In the multivariable analysis, people with HIV with nadir CD4 counts of more than 350 cells per µL had the lowest risk of developing anal cancer, compared with people with HIV with counts of less than 200 cells per µL (adjusted IR ratio 0·03, 95% CI 0·00-0·25; p=0·0010) or 200-350 cells per µL (0·30, 0·17-0·55; p<0·0001). Compared with people with HIV younger than 30 years, people with HIV aged 60 years and older had an adjusted IR ratio of 27·6 (3·7-206·9; p=0·0010) and people with HIV aged 45-59 years of 21·6 (3·0-156·4; p=0·0020). Compared with individuals diagnosed after 2015, a diagnosis of HIV before 1998 had an adjusted IR ratio of 33·0 (7·9-137·5; p<0·0001). INTERPRETATION: A nadir CD4 count threshold below 350 cells per µL, particularly less than 200 cells per µL, has the potential to identify people with HIV at heightened risk of developing anal cancer. Customised screening strategies that prioritise screening for individuals at high risk with this surrogate marker could maximise available resources. External validation of these data with other cohorts is required before screening recommendations can be updated. FUNDING: Catalan Health Department, Generalitat de Catalunya.
RESUMO
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.
RESUMO
BACKGROUND: Quantification and description of patients recently infected by HIV can provide an accurate estimate of the dynamics of HIV transmission. Between 2006 and 2008 in Catalonia, we estimated the prevalence of recent HIV infection among newly diagnosed cases, described the epidemiological characteristics of the infection according to whether it was recent, long-standing or advanced, and identified factors associated with recent infection. METHODS: A Test for Recent Infection (TRI) was performed in serum samples from patients newly diagnosed with HIV. Two different TRI were used: the Vironostika-LS assay (January 2006-May 2007) and the BED-CEIA CEIA (June 2007 onwards). Samples were obtained within the first 6 months of diagnosis. Patients whose samples tested positive in the TRI were considered recently infected. RESULTS: Of 1125 newly diagnosed patients, 79.9% were men (median age, 35.4 years), 38.7% were born outside Spain, 48.9% were men who have sex with men (MSM) and 10.6% presented other sexually transmitted infections. The overall percentage of recent infection was 23.0%, which increased significantly, from 18.1% in 2006 to 26.2% in 2008. This percentage was higher for patients from South America (27.6%). Factors associated with recent infection were acquiring infection through sexual contact between MSM [odds ratio (OR) 2.0; 95% confidence interval (95% CI) 1.1-3.9], compared with acquiring infection through heterosexual relations and being under 30 years of age (OR 5.9; 95% CI 1.9-17.4), compared with being over 50 years of age. CONCLUSION: The highest percentage of recent infection was identified in MSM, suggesting either a higher incidence or a greater frequency of HIV testing. Information regarding testing patterns is necessary to correctly interpret data from recently infected individuals. Systems to monitor the HIV epidemic should include both parameters.

People living with HIV (PLWH) are prioritised for SARS-CoV-2 vaccination due to their vulnerability to severe COVID-19. Therefore, the epidemiological surveillance of vaccination coverage and the timely identification of suboptimally vaccinated PLWH is vital. We assessed SARS-CoV-2 vaccination coverage and factors associated with under-vaccination among PLWH in Catalonia, Spain. As of 11.12.2021, 9945/14942 PLWH (66.6%) had received ≥1 dose of a SARS-CoV-2 vaccine. Non-Spanish origin (adjusted odds ratio (aOR) 0.64, 95% CI 0.59−0.70), CD4 count of 200−349 cells/µL (aOR 0.74, 95% CI 0.64−0.86) or 350−499 cells/µL (aOR 0.79, 95% CI 0.70−0.88), detectable plasma HIV-RNA (aOR 0.61 95% CI 0.53−0.70), and previous SARS-CoV-2 diagnosis (aOR 0.58 95% CI 0.51−0.65) were associated with under-vaccination. SARS-CoV-2 diagnosis (437 [9.5%] vs. 323 [3.5%], p < 0.001), associated hospitalisations (10 [2.3%] vs. 0 [0%], p < 0.001), intensive care unit admissions (6 [1.4%] vs. 0 [0%], p < 0.001), and deaths (10 [2.3%] vs. 0 [0%], p < 0.001) were higher among unvaccinated PLWH. Vaccination coverage was lower among PLWH with a CD4 count >200 cells/µL, detectable plasma HIV-RNA, previous SARS-CoV-2 diagnosis, and migrants. SARS-CoV-2 diagnosis, associated hospitalisations, and deaths among PLWH were lower among the vaccinated compared with the unvaccinated. SARS-CoV-2 vaccination prioritisation has not completely reached vulnerable PLWH with poorer prognosis. This information can be used to inform public health strategies.
RESUMO
OBJECTIVES: The objectives of this study were to assess the prevalence of transmitted HIV-1 drug resistances (TDR) and HIV-1 subtypes in recently infected patients in Catalonia between 2003 and 2005 and to describe the characteristics of these patients according to the presence or absence of TDR and HIV-1 subtype. METHODS: After application of the Serological Testing Algorithm for Recent HIV Seroconversion (STARHS), residual aliquots of serum samples from recently infected antiretroviral-naïve individuals were genotyped. FASTA sequences were analyzed using the HIVDB Program. The World Health Organization 2009 List of Mutations for Surveillance of Transmitted HIV-1 Drug Resistant HIV Strains was used to estimate the prevalence of TDR. RESULTS: Of 182 recently infected patients, 14 (7.7%) presented TDR. Seven (3.8%) had genotypic evidence of TDR against non-nucleoside reverse transcriptase inhibitors, 6 (3.3%) against nucleoside reverse transcriptase inhibitors, 3 (1.6%) against protease inhibitors (PIs), and only 2 individuals (1.1%) presented TDR against more than one class of drugs. Thirty-five (19.2%) patients were infected with a non-B HIV-1 subtype. CONCLUSION: This is the first study to estimate the prevalence of TDR in recently infected patients in Catalonia. The results are similar to those of studies performed in other Spanish regions. Correct monitoring of these parameters requires systematic epidemiologic surveillance of transmitted resistance.

BACKGROUND: We assessed the prevalence of antibodies against hepatitis C virus (HCV-Abs) and active HCV infection in patients infected with human immunodeficiency virus (HIV) in Spain in 2016 and compared the results with those of similar studies performed in 2002, 2009, and 2015. METHODS: The study was performed in 43 centers during October-November 2016. The sample was estimated for an accuracy of 2% and selected by proportional allocation and simple random sampling. During 2016, criteria for therapy based on direct-acting antiviral agents (DAA) were at least significant liver fibrosis, severe extrahepatic manifestations of HCV, and high risk of HCV transmissibility. RESULTS: The reference population and the sample size were 38904 and 1588 patients, respectively. The prevalence of HCV-Abs in 2002, 2009, 2015, and 2016 was 60.8%, 50.2%, 37.7%, and 34.6%, respectively (P trend <.001, from 2002 to 2015). The prevalence of active HCV in 2002, 2009, 2015, and 2016 was 54.0%, 34.0%, 22.1%, and 11.7%, respectively (P trend <.001). The anti-HCV treatment uptake in 2002, 2009, 2015, and 2016 was 23.0%, 48.0%, 59.3%, and 74.7%, respectively (P trend <.001). In 2016, HCV-related cirrhosis was present in 7.6% of all HIV-infected individuals, 15.0% of patients with active HCV, and 31.5% of patients who cleared HCV after anti-HCV therapy. CONCLUSIONS: Our findings suggest that with universal access to DAA-based therapy and continued efforts in prevention and screening, it will be possible to eliminate active HCV among HIV-infected individuals in Spain in the short term. However, the burden of HCV-related cirrhosis will continue to be significant among HIV-infected individuals.
