RESUMEN

Metabolic-dysfunction-associated fatty liver disease (MAFLD) is a comorbidity that generally increases in people living with HIV (PLWH). This condition is usually accompanied by persistent inflammation and premature immune system aging. In this prospective cohort study, we describe a straightforward methodology for quantifying biomarkers of aging, such as DNA methylation and telomere length, in PLWH and in the context of another relevant condition, such as MAFLD. Fifty-seven samples in total, thirty-eight from PLWH and nineteen from non-PLWH participants with or without MAFLD, were obtained and subjected to DNA extraction from peripheral blood mononuclear cells (PBMCs). Global DNA methylation and telomere length quantification were performed using an adapted enzyme-linked immunosorbent assay (ELISA) and qPCR, respectively. The quantification results were analysed and corrected by clinically relevant variables in this context, such as age, sex, and metabolic syndrome. Our results show an increased association of these biomarkers in PLWH regardless of their MAFLD status. Thus, we propose including the quantification of these age-related factors in studies of comorbidities. This will allow a better understanding of the effect of comorbidities of HIV infection and MAFLD and prevent their effects in these populations in the future.

RESUMEN

OBJECTIVES: To assess the effectiveness and tolerability of dolutegravir (DTG)/lamivudine (3TC) among treatment-naive and virologically suppressed treatment-experienced individuals in the multicentre cohort of the Spanish HIV/AIDS Research Network (CoRIS) during the years 2018-2021. METHODS: We used multivariable regression models to compare viral suppression (VS) [HIV RNA viral load (VL) <50 copies/mL] and the change in CD4 cell counts at 24 and 48 (±12) weeks after initiation with dolutegravir/lamivudine or other first-line ART regimens. RESULTS: We included 2160 treatment-naive subjects, among whom 401 (18.6%) started with dolutegravir/lamivudine. The remaining subjects started bictegravir (BIC)/emtricitabine (FTC)/tenofovir alafenamide (TAF) (n = 949, 43.9%), DTG + FTC/tenofovir disoproxil fumarate (TDF) (n = 282, 13.1%), DTG/3TC/abacavir (ABC) (n = 255, 11.8%), darunavir (DRV)/cobicistat(COBI)/FTC/TAF (n = 147, 6.8%) and elvitegravir (EVG)/COBI/FTC/TAF (n = 126, 5.8%). At 24 and 48 weeks after starting dolutegravir/lamivudine, 91.4% and 93.8% of the subjects, respectively, achieved VS. The probability of achieving VS with dolutegravir/lamivudine was not significantly different compared with any other regimen at 24 or 48 weeks, with the exception of a lower chance of achieving VS at 24 weeks for DRV/COBI/FTC/TAF (adjusted OR: 0.47; 95% CI: 0.30-0.74) compared with dolutegravir/lamivudine.For the analysis of treatment-experienced virally suppressed subjects we included 1456 individuals who switched to dolutegravir/lamivudine, among whom 97.4% and 95.5% maintained VS at 24 and 48 weeks, respectively. During the first 48 weeks after dolutegravir/lamivudine initiation, 1.0% of treatment-naive and 1.5% of treatment-experienced subjects discontinued dolutegravir/lamivudine due to an adverse event. CONCLUSIONS: In this large multicentre cohort, effectiveness and tolerability of dolutegravir/lamivudine were high among treatment-naive and treatment-experienced subjects.

RESUMEN

To evaluate the prevalence of transmitted drug resistance (TDR) to nucleoside and nonnucleoside reverse transcriptase inhibitors (NRTI, NNRTI), protease inhibitors (PI), and integrase strand transfer inhibitors (INSTI) in Spain during the period 2019-2021, as well as to evaluate transmitted clinically relevant resistance (TCRR) to antiretroviral drugs. Reverse transcriptase (RT), protease (Pro), and Integrase (IN) sequences from 1824 PLWH (people living with HIV) were studied. To evaluate TDR we investigated the prevalence of surveillance drug resistance mutations (SDRM). To evaluate TCRR (any resistance level ≥ 3), and for HIV subtyping we used the Stanford v.9.4.1 HIVDB Algorithm and an in-depth phylogenetic analysis. The prevalence of NRTI SDRMs was 3.8% (95% CI, 2.8%-4.6%), 6.1% (95% CI, 5.0%-7.3%) for NNRTI, 0.9% (95% CI, 0.5%-1.4%) for PI, and 0.2% (95% CI, 0.0%-0.9%) for INSTI. The prevalence of TCRR to NRTI was 2.1% (95% CI, 1.5%-2.9%), 11.8% for NNRTI, (95% CI, 10.3%-13.5%), 0.2% (95% CI, 0.1%-0.6%) for PI, and 2.5% (95% CI, 1.5%-4.1%) for INSTI. Most of the patients were infected by subtype B (79.8%), while the majority of non-Bs were CRF02_AG (n = 109, 6%). The prevalence of INSTI and PI resistance in Spain during the period 2019-2021 is low, while NRTI resistance is moderate, and NNRTI resistance is the highest. Our results support the use of integrase inhibitors as first-line treatment in Spain. Our findings highlight the importance of ongoing surveillance of TDR to antiretroviral drugs in PLWH particularly with regard to first-line antiretroviral therapy.

RESUMEN

Mental disorders hamper immunological control of HIV infection by exerting a negative influence on antiretroviral therapy (ART) adherence. We sought to address the possible relationship between non-adherence to antiretroviral treatment (ART), mental disorders and substance use in people living with HIV/AIDS (PLWHA) in Spain, which presents a high prevalence of intravenously transmitted HIV infection. We assessed 125 PLWHA attending regular outpatient follow-up. The main adherence measure was pill collection from the Hospital Pharmacy. We included sociodemographic variables, mental disorders diagnosis, and substance use in the 12 months prior to the assessment. Harmful alcohol consumption (OR: 6.834; 95% CI: 2.008-23.257; p = 0.002), suffering from depression (OR: 5.851; 95% CI: 1.470-23.283; p = 0.012) and being at risk of suicide (OR: 3.495; 95% CI: 1.136-10.757; p = 0.029) increased the likelihood of non-adherence. 29.6% of the sample had been infected via blood contact. HCV co-infection was present in 46.4% of the study sample, increasing the likelihood of non-adherence (OR: 3.223; 95% CI: 1.119-9.286; p = 0.030). Harmful alcohol use and some serious mental disorders (especially depression and suicide risk) are consistently associated with non-adherence to ART. HCV co-infection could be an important risk marker of non-adherence among PLWHA with a high prevalence of intravenous drug use.

RESUMEN

A woman with mild coronavirus disease 2019 developed cervical adenopathy, being diagnosed of Epstein-Barr virus infectious mononucleosis. We performed fine needle aspiration, and demonstrate that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is found in lymph nodes even in mild disease along with a strong expansion of terminally differentiated effector memory CD4+ T cells, a cell population that is practically absent in lymph nodes.

RESUMEN

OBJECTIVES: With the goal of facilitating the use of HIV-TRePS to optimize therapy in settings with limited healthcare resources, we aimed to develop computational models to predict treatment responses accurately in the absence of commonly used baseline data. METHODS: Twelve sets of random forest models were trained using very large, global datasets to predict either the probability of virological response (classifier models) or the absolute change in viral load in response to a new regimen (absolute models) following virological failure. Two 'standard' models were developed with all baseline variables present and 10 others developed without HIV genotype, time on therapy, CD4 count or any combination of the above. RESULTS: The standard classifier models achieved an AUC of 0.89 in cross-validation and independent testing. Models with missing variables achieved AUC values of 0.78-0.90. The standard absolute models made predictions that correlated significantly with observed changes in viral load with a mean absolute error of 0.65 log10 copies HIV RNA/mL in cross-validation and 0.69 log10 copies HIV RNA/mL in independent testing. Models with missing variables achieved values of 0.65-0.75 log10 copies HIV RNA/mL. All models identified alternative regimens that were predicted to be effective for the vast majority of cases where the new regimen prescribed in the clinic failed. All models were significantly better predictors of treatment response than genotyping with rules-based interpretation. CONCLUSIONS: These latest models that predict treatment responses accurately, even when a number of baseline variables are not available, are a major advance with greatly enhanced potential benefit, particularly in resource-limited settings. The only obstacle to realizing this potential is the willingness of healthcare professions to use the system.

RESUMEN

BACKGROUND: Cobicistat, dolutegravir and rilpivirine are all modest inhibitors of proximal tubular creatinine secretion (IPTCrS) and hence a moderate and early non-progressive creatinine estimated glomerular filtration rate (Cr-eGFR) reduction has been observed in clinical trials. Data regarding the impact of combination of those drugs on Cr-eGFR, in the clinical practice, are scarcely known. METHODS: Changes in Cr-eGFR after starting darunavir/cobicistat alone or in combination with dolutegravir and/or rilpivirine were studied in a nationwide retrospective cohort study of consecutive HIV-infected patients initiating darunavir/cobicistat. The relationship between Cr-eGFR changes over time and the use of darunavir/cobicistat alone or darunavir/cobicistat plus dolutegravir and/or rilpivirine adjusted by different HIV patient's characteristics, socio-demographics, HIV severity and use of tenofovir concomitant medication other than antiretrovirals was explored through univariate and multivariate analyses. RESULTS: The analysis included 725 patients. At 48 weeks, the combination of two or more IPTCrS (darunavir/cobicistat with rilpivirine and/or dolutegravir) was associated with higher decreases in Cr-eGFR [adjusted median difference (±SD) -3.5 ± 1.6 (95% CI -6.6 to -0.3), P = 0.047], and a decrease up to or higher than 15 mL/min/1.73 m2 was more frequent [adjusted OR 3.233 (95% CI 1.343-7.782), P = 0.009], with respect to darunavir/cobicistat alone. The Cr-eGFR changes between darunavir/cobicistat and darunavir/cobicistat with rilpivirine and/or dolutegravir showed more significant decreases in patients taking two or more IPTCrS at 12, 24 and 48 weeks. (ClinicalTrials.gov: NCT03042390). CONCLUSIONS: Concomitant use of darunavir/cobicistat plus IPTCrS dolutegravir, rilpivirine, or both produced an additive effect in the expected Cr-eGFR decrease.

RESUMEN

Hepatitis C virus (HCV) and HIV are major causes of worldwide disease. We aimed to evaluate the effect of a combined screening programme, which included a risk-assessment questionnaire and rapid tests for point-of-care diagnosis, on screening and new diagnosis rates. This prospective, cluster randomized study was carried out in primary care. The intervention arm included a 4-hour educational programme, the use of a risk-assessment questionnaire and rapid tests. In the control centres, only the educational intervention was provided. The main variables compared were the screening coverage and the number and rate of new HCV and HIV diagnoses. Of a total of 7991 participants, 4670 (58.5%) and 2894 (36.2%) presented a risk questionnaire for HIV or HCV, respectively. The younger participants, men and those from Latin America and Eastern Europe, showed the greatest risk of presenting with a positive questionnaire. The overall screening coverage was higher within the intervention arm (OR 17.7; 95% CI 16.2-19.5; P < .001). Only two HIV-positives were identified compared to one in control centres. The rate of HCV diagnoses was higher among intervention centres, with 37 versus seven positive tests (OR 5.2; 95% CI 2.3-11.6; P < .001). Of them, 10 were new diagnoses and 27 had been previously diagnosed, although not linked to care. In conclusion, a simple operational programme can lead to an increase in HCV and HIV screening rates, compared to an exclusively educational programme. The selection of at-risk patients with a self-questionnaire and the use of rapid tests significantly increased the diagnostic rate of HCV infection.

RESUMEN

BACKGROUND: HIV infection has become a chronic disease and well-being of people living with HIV (PLHIV) is now of particular concern. The objectives of this paper were to describe self-rated health among PLHIV, on ART and on ART virally suppressed and to analyse its determinants. METHODS: Data were obtained from a second-generation surveillance system based on a cross-sectional one-day survey in public hospitals. Epidemiological and clinical data were collected among HIV-infected inpatients and outpatients receiving HIV-related care the day of the survey in 86 hospitals in 2019. Self-rated health was measured using a question included in the National Health Survey: "In the last 12 months, how would you rate your health status?" an ordinal variable with five categories (very good, good, moderate, bad and very bad). For the analysis, these responses were dichotomized into two categories: 1 = very good/good and 0 = moderate, bad or very bad health status. Factors associated with very good/good self-rated health were estimated using logistic regression. RESULTS: Of 800 PLHIV, 67.5% perceived their health as very good/good, 68.4% among PLHIV on ART and 71.7% of those virally suppressed. Having university education (adjusted odds ratio (aOR):2.1), being unemployed (aOR:0.3) or retired (aOR:0.2), ever being diagnosed of AIDS (aOR:0.6), comorbidities (aOR:0.3), less than 2 year since HIV diagnosis (aOR:0.3) and not receiving ART (aOR:0.3) were associated with good self-rated health. Moreover, among PLHIV on ART, viral load less than 200 copies (aOR:3.2) were related to better perceived health. Bad adherence was inversely associated with good self-rated health among PLHIV on ART (aOR:0.5) and of those virally suppressed (aOR:0.4). CONCLUSIONS: Nearly seven in 10 PLHIV in Spain considered their health status as very good/good, being higher among virally suppressed PLHIV. Both demographic and clinical determinants affect quality of life.

RESUMEN

BACKGROUND: To estimate the prevalence and severity of menopausal symptoms and anxiety/depression and to assess the differences according to menopausal status among women living with HIV aged 45-60 years from the cohort of Spanish HIV/AIDS Research Network (CoRIS). METHODS: Women were interviewed by phone between September 2017 and December 2018 to determine whether they had experienced menopausal symptoms and anxiety/depression. The Menopause Rating Scale was used to evaluate the prevalence and severity of symptoms related to menopause in three subscales: somatic, psychologic and urogenital; and the 4-item Patient Health Questionnaire was used for anxiety/depression. Logistic regression models were used to estimate odds ratios (ORs) of association between menopausal status, and other potential risk factors, the presence and severity of somatic, psychological and urogenital symptoms and of anxiety/depression. RESULTS: Of 251 women included, 137 (54.6%) were post-, 70 (27.9%) peri- and 44 (17.5%) pre-menopausal, respectively. Median age of onset menopause was 48 years (IQR 45-50). The proportions of pre-, peri- and post-menopausal women who had experienced any menopausal symptoms were 45.5%, 60.0% and 66.4%, respectively. Both peri- and post-menopause were associated with a higher likelihood of having somatic symptoms (aOR 3.01; 95% CI 1.38-6.55 and 2.63; 1.44-4.81, respectively), while post-menopause increased the likelihood of having psychological (2.16; 1.13-4.14) and urogenital symptoms (2.54; 1.42-4.85). By other hand, post-menopausal women had a statistically significant five-fold increase in the likelihood of presenting severe urogenital symptoms than pre-menopausal women (4.90; 1.74-13.84). No significant differences by menopausal status were found for anxiety/depression. Joint/muscle problems, exhaustion and sleeping disorders were the most commonly reported symptoms among all women. Differences in the prevalences of vaginal dryness (p = 0.002), joint/muscle complaints (p = 0.032), and sweating/flush (p = 0.032) were found among the three groups. CONCLUSIONS: Women living with HIV experienced a wide variety of menopausal symptoms, some of them initiated before women had any menstrual irregularity. We found a higher likelihood of somatic symptoms in peri- and post-menopausal women, while a higher likelihood of psychological and urogenital symptoms was found in post-menopausal women. Most somatic symptoms were of low or moderate severity, probably due to the good clinical and immunological situation of these women.

RESUMEN

BACKGROUND: The aim of this study was to investigate the effectiveness and tolerability of the combination elvitegravir/cobicistat/tenofovir/emtricitabine plus darunavir (EVG/COB/TFV/FTC + DRV) in treatment-experienced patients from the cohort of the Spanish HIV/AIDS Research Network (CoRIS). METHODS: Treatment-experienced patients starting treatment with EVG/COB/TFV/FTC + DRV during the years 2014-2018 and with more than 24 weeks of follow-up were included. TFV could be administered either as tenofovir disoproxil fumarate or tenofovir alafenamide. We evaluated virological response, defined as viral load (VL) < 50 copies/ml and < 200 copies/ml at 24 and 48 weeks after starting this regimen, stratified by baseline VL (< 50 or ≥ 50 copies/ml at the start of the regimen). RESULTS: We included 39 patients (12.8% women). At baseline, 10 (25.6%) patients had VL < 50 copies/ml and 29 (74.4%) had ≥ 50 copies/ml. Among patients with baseline VL < 50 copies/ml, 85.7% and 80.0% had VL < 50 copies/ml at 24 and 48 weeks, respectively, and 100% had VL < 200 copies/ml at 24 and 48 weeks. Among patients with baseline VL ≥ 50 copies/ml, 42.3% and 40.9% had VL < 50 copies/ml and 69.2% and 68.2% had VL < 200 copies/ml at 24 and 48 weeks. During the first 48 weeks, no patients changed their treatment due to toxicity, and 4 patients (all with baseline VL ≥ 50 copies/ml) changed due to virological failure. CONCLUSIONS: EVG/COB/TFV/FTC + DRV was well tolerated and effective in treatment-experienced patients with undetectable viral load as a simplification strategy, allowing once-daily, two-pill regimen with three antiretroviral drug classes. Effectiveness was low in patients with detectable viral loads.

RESUMEN

BACKGROUND: Integrase strand-transfer inhibitors (INSTIs) constitute at present one of the pillars of first-line ART. OBJECTIVES: To study the prevalence of and the trend in transmitted drug resistance (TDR) to INSTIs in ART-naive patients in Spain. METHODS: During the period 2012-17, 1109 patients from CoRIS were analysed. The Stanford algorithm v8.7 was used to evaluate TDR and transmission of clinically relevant resistance. To describe individual mutations/polymorphisms, the most recent IAS list (for INSTIs) and the 2009 WHO list update (for the backbone NRTIs used in combination with INSTIs in first-line treatment) were used. RESULTS: Clinically relevant resistance to the INSTI class was 0.2%: T66I, 0.1%, resistance to elvitegravir and intermediate resistance to raltegravir; and G163K, 0.1%, intermediate resistance to raltegravir and elvitegravir. No clinical resistance to dolutegravir or bictegravir was observed. The prevalence of INSTI TDR following the IAS-USA INSTI mutation list was 2.6%, with no trend towards changes in the prevalence throughout the study period. The overall prevalence of NRTI WHO mutations was 4.3%, whereas clinically relevant resistance to tenofovir, abacavir and emtricitabine/lamivudine was 1.7%, 1.9% and 0.7%, respectively. CONCLUSIONS: Given the low prevalence of clinically relevant resistance to INSTIs and first-line NRTIs in Spain, it is very unlikely that a newly diagnosed patient will present with clinical resistance to a first-line INSTI-based regimen. These patients may not benefit from INSTI and NRTI baseline resistance testing.

RESUMEN

Objectives: Optimizing antiretroviral drug combination on an individual basis can be challenging, particularly in settings with limited access to drugs and genotypic resistance testing. Here we describe our latest computational models to predict treatment responses, with or without a genotype, and compare their predictive accuracy with that of genotyping. Methods: Random forest models were trained to predict the probability of virological response to a new therapy introduced following virological failure using up to 50 000 treatment change episodes (TCEs) without a genotype and 18 000 TCEs including genotypes. Independent data sets were used to evaluate the models. This study tested the effects on model accuracy of relaxing the baseline data timing windows, the use of a new filter to exclude probable non-adherent cases and the addition of maraviroc, tipranavir and elvitegravir to the system. Results: The no-genotype models achieved area under the receiver operator characteristic curve (AUC) values of 0.82 and 0.81 using the standard and relaxed baseline data windows, respectively. The genotype models achieved AUC values of 0.86 with the new non-adherence filter and 0.84 without. Both sets of models were significantly more accurate than genotyping with rules-based interpretation, which achieved AUC values of only 0.55-0.63, and were marginally more accurate than previous models. The models were able to identify alternative regimens that were predicted to be effective for the vast majority of cases in which the new regimen prescribed in the clinic failed. Conclusions: These latest global models predict treatment responses accurately even without a genotype and have the potential to help optimize therapy, particularly in resource-limited settings.

RESUMEN

OBJECTIVES: The objective of this study was to evaluate the incidence, prevalence and clinical consequences of virological failure (VF) to raltegravir-based regimens in Spain. METHODS: A multicentre, retrospective, observational study was performed in 10 tertiary hospitals (January 2006 to June 2013). The study included HIV-1-infected patients with loss of virological suppression (LVS; two consecutive HIV-1 RNA ≥50 copies/mL) while receiving raltegravir. VF and low-level viraemia (LLV) were defined as two consecutive HIV-1 RNA ≥200 copies/mL and 50 to <200 copies/mL, respectively. Integrase strand-transfer inhibitor resistance was investigated at LVS. During the 48 weeks following LVS, recorded data included clinical characteristics, treatment discontinuations, AIDS-associated events and deaths. Effectiveness of therapy following LVS was evaluated by ITT and PP. Multivariate regression was used to assess predictors of efficacy. RESULTS: Of the 15 009 HIV-infected patients in participating centres, 2782 (18.5%) had received raltegravir-based regimens. Of those, 192 (6.9%), 125 (4.5%) and 67 (2.4%) experienced LVS, VF and LLV, respectively. The incidence of VF was 1.8 (95% CI, 1.5-2.1) per 100 patients/year. The prevalence of VF was 4.5% (95% CI, 3.8%-5.3%). Integrase-associated mutations were found in 78.8% of patients with integrase genotyping results available. High-level resistance to dolutegravir was not observed. Salvage therapy failed in 34.1% of patients; progression to AIDS/death occurred in 8.3% during the first year following LVS. The latter was associated with intravenous drug use, time on raltegravir and lower CD4+ count nadir in patients who started raltegravir-based treatments as salvage regimens. CONCLUSIONS: VF with raltegravir is infrequent, but often associated with major clinical complications in treatment-experienced patients.

RESUMEN

BACKGROUND: Immigrant women living with HIV generally have worse adherence to medical treatment and follow-up when compared to native women and immigrant or native men. The general aim of this study was to improve healthcare services for HIV-positive women and to better understand why some of them discontinue treatment. The specific objectives were: (1) to explore the barriers and facilitators to medical follow-up among women and (2) to use the findings to create a guide for healthcare professionals with strategies and tools to encourage the immigrant women to continue with their healthcare treatment. METHODS: We conducted a qualitative, patient-centred research based on semi-structured interviews in order to understand the drivers and barriers for HIV positive immigrant women to adhere to medical follow-up. A total of 26 women in active or discontinued treatment (from sub-Saharan Africa (10), Latin America (8) and Spain (8)) were interviewed in 2012 using a purposive sampling methodology. The semi-structured interviews were transcribed and analysed based on the grounded theory approach and the framework method. Three researchers took part in the triangulation of results.The study was approved by the Ethical Committee of the Hospital Universitario Ramón y Cajal. RESULTS: The study revealed eight categories that impacted adherence to treatment and medical follow-up: doctor-patient relationship, relationship between body and HIV, employment, gender roles, representations of AIDS, emotional support received, trust in biomedical system, and psychological condition. Specific barriers and facilitators related to these categories were identified. In immigrant women, the influence of these barriers was greater than in Spanish women.Recommendations for healthcare professionals based on this study have been compiled in an informative brochure. CONCLUSIONS: Social, cultural, and psychological aspects as well as self-perception of body changes, gender roles, and the relationship with the healthcare system, are key elements that may affect the adherence to medical treatment of immigrant women living with HIV.Qualitative research focused on the comprehensive experience of living with HIV can be useful for creating tools that pave the way to detect barriers and facilitators to medical follow-up in specific populations.

RESUMEN

In this update, antiretroviral therapy (ART) is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The strength and grade of the recommendation varies with clinical circumstances, number of CD4 cells, comorbid conditions and prevention of transmission of HIV. The objective of ART is to achieve an undetectable plasma viral load. Initial ART should always comprise a combination of 3 drugs, including 2 nucleoside reverse transcriptase inhibitors and a third drug from a different family (non-nucleoside reverse transcriptase inhibitor, protease inhibitor, or integrase inhibitor). This update presents the causes and criteria for switching ART in patients with undetectable plasma viral load and in cases of virological failure. An update is also provided for the specific criteria for ART in special situations (acute infection, HIV-2 infection, and pregnancy) and with comorbid conditions (tuberculosis or other opportunistic infections, kidney disease, liver disease, and cancer).

RESUMEN

The current reality of the diagnosis and treatment of HIV infection justifies a multidisciplinary and coordinated approach between Primary Care and Hospital Care, contemplating bidirectionality and communication between the two care settings. The consensus document, coordinated by the AIDS Study Group of the Spanish Society of Infectious Diseases and Clinical Microbiology (SEIMC-GeSIDA) and the Spanish Society of Family and Community Medicine (semFYC), was born out of this need. Here, the recommendations of the four sections that comprise it are summarized: the first deals with aspects of prevention and diagnosis of HIV infection; the second contemplates the clinical care of people living with HIV; the third deals with social factors, including legal and confidentiality issues, quality of life, and the role of NGOs; finally, the fourth block addresses bidirectional and shared training/teaching and research.

RESUMEN

BACKGROUND: Ending AIDS by 2030 requires improvements across all stages of the HIV care continuum. We used a longitudinal approach to assess changes in the HIV care continuum in Spain and transition probabilities across different stages. METHODS: We used data from the prospective Cohort of the Spanish HIV/AIDS Research Network to analyse the time from diagnosis to linkage to care, linkage to care to antiretroviral therapy (ART), and ART to viral suppression in five calendar periods defined by milestones in ART, from 2005 to 2022. We used the Kaplan-Meier method and Cox proportional hazard models to estimate cumulative probabilities of stage transition within 1, 3, 6, and 12 months of stage eligibility, by period. FINDINGS: We included 18 529 participants. Comparing the initial (2005-09) and final (2020-22) periods, time to linkage to care decreased from a median of 6·0 weeks to 1·3 weeks, time to ART initiation from 15·9 weeks to 0·4 weeks, and time to viral suppression from 13·3 weeks to 7·1 weeks. Adjusted hazard ratios for the comparison between the last period and the initial period were 3·1 (95% CI 2·8-3·4) for linkage to care within 1 month, 11·4 (10·1-12·3) for ART initiation within 1 month, and 2·2 (1·2-2·4) for viral suppression within 3 months. The aggregate proportion of late diagnoses was 38·6%, increasing after 2012 to 46·4% in the 2020-22 period. Same-day ART initiation increased from 18% to 39% from 2005 to 2022. The overall incidence rate of virological failure was 1·05 failures per 1000 person-years and showed a non-significant decline throughout the study. INTERPRETATION: The great improvement in transition times through the HIV care cascade might put Spain on the verge of achieving the UNAIDS targets for HIV elimination. However, late diagnosis remains a challenge that should be addressed. FUNDING: Instituto de Salud Carlos III and Spanish AIDS Research Network.

RESUMEN

BACKGROUND AND IMPORTANCE: The rates of hidden infection and late diagnosis of HIV still remain high in Western countries. Missed diagnostic opportunities represent the key point in changing the course of the epidemic. OBJECTIVE: To evaluate the feasibility and results of implementation of a selective strategy to test for HIV in the emergency department (ED) in patients with six pre-defined medical situations: sexually transmitted infections, herpes zoster, community-acquired pneumonia, mononucleosis syndrome, practice of chemsex (CS) or request of post-exposure prophylaxis. DESIGN: This quasi-experimental longitudinal study evaluated the pre- and post-implementation results of HIV testing in the six aforementioned clinical scenarios. SETTINGS AND PARTICIPANTS: Patients attended 34 Spanish EDs. INTERVENTION OR EXPOSURE: The intervention was an intensive educational program and pathways to facilitate and track orders and results were designed. We collected and compared pre- and post-implementation ED census and diagnoses, and HIV tests requested and results. OUTCOME MEASURES AND ANALYSIS: The main outcome was adherence to the recommendations. Secondary outcomes were to evaluate the effectiveness of the program by the rate of positive test and the new HIV diagnoses. Differences between first and second periods were assessed. The magnitude of changes (absolute and relative) was expressed with the 95% confidence interval (CI). MAIN RESULTS: HIV tests increasing from 7080 (0.42% of ED visits) to 13 436 (relative increase of 75%, 95% CI from 70 to 80%). The six conditions were diagnosed in 15 879 and 16 618 patients, and HIV testing was ordered in 3393 (21%) and 7002 (42%) patients (increase: 97%; 95% CI: 90-104%). HIV testing significantly increased for all conditions except for CS. The positive HIV test rates increased from 0.92 to 1.67%. Detection of persons with undiagnosed HIV increased from 65 to 224, which implied a 220% (95% CI: 143-322%) increase of HIV diagnosis among all ED comers and a 71% (95% CI: 30-125%) increase of positive HIV tests. CONCLUSION: Implementation of a strategy to test for HIV in selective clinical situations in the ED is feasible and may lead to a substantial increase in HIV testing and diagnoses.
