Design and Proof of Concept of a Web-Based Questionnaire to Identify Patients at Risk for HIV and HCV Infection.

Despite remarkable improvement in the human immunodeficiency virus (HIV) and hepatitis C virus (HCV) care continuum, the rate of late diagnosis of HIV and HCV in high-income countries remains unacceptably high. Testing relies mainly on primary care physicians' identification of risk factors. We aimed to adapt an analogic to an online questionnaire to help HIV and HCV screening and perform a pilot study to assess its accuracy and acceptability.

Transition times across the HIV care continuum in Spain from 2005 to 2022: a longitudinal cohort study.

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.

Efficacy and safety of dolutegravir/lamivudine in virologically suppressed female participants: week 48 data from the pooled TANGO and SALSA studies.

Objectives: Women represent >50% of people with HIV globally but have historically been underrepresented in clinical trials. We evaluated the efficacy and safety of switching to dolutegravir/lamivudine (DTG/3TC) vs continuing their current antiretroviral regimen (CAR) by sex assigned at birth (female and male) in virologically suppressed adults with HIV-1 without prior virological failure in a pooled analysis of two randomized controlled trials.

Methods: This analysis included 48-week data from the phase 3 TANGO and SALSA studies.

Transmitted drug resistance to antiretroviral drugs in Spain during the period 2019-2021.

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).

Executive summary of the consensus document on the shared care of patients with HIV infection between primary and hospital care.

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.

Description of mpox reinfection by whole genome sequencing.

Several possible mpox reinfections have been reported, however, the debate on whether these are confirmed reinfections remains open. A 30-year-old male living with HIV and a history of single-dose mpox vaccination, first diagnosed with mpox in September 2022, presented with genital ulcers in March 2023, testing positive for mpox virus. Real-time polymerase chain reaction revealed the presence of viral DNA with cycle threshold values of 24 and 25, respectively.

Global DNA methylation and telomere length as markers of accelerated aging in people living with HIV and non-alcoholic fatty liver disease.

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.

Vaccination trends in people with HIV infection participanting in the hospital-based survey of patients infected with HIV, 2006-2021.

Objective: To assess the trend in hepatitis A, hepatitis B, pneumococcal, tetanus and seasonal influenza vaccination in people with HIV infection and to analyse associated factors.

Methods: The Hospital Survey of Patients with HIV, an annual cross-sectional study conducted on a fixed day (2006-2021), was used. Inpatients and outpatients were included.

HIV and HCV screening by non-infectious diseases physicians: can we improve testing and hidden infection rates?

Background: Missed opportunities for Human Immunodeficiency Virus (HIV) and Hepatitis C Virus (HCV) testing remain high. We aimed to ascertain the knowledge of screening guidelines and attitudes of non-infectious disease (ID) hospital physicians and assess the impact of a 1-h session on screening rates and diagnoses.

Methods: This interventional study consisted of a 1-h training session on HIV and HCV epidemiology and testing guidelines for non-ID physicians.

Impact of COVID-19 on the Care of Patients with HIV Infection.

The COVID-19 pandemic and associated lockdown measures have been associated with substantial disruptions to health care services, including screening for human immunodeficiency virus (HIV) and management of people living with HIV (PLWH). Data from 3265 patients were examined in a retrospective cohort study. We compared outpatient follow-up for PLWH, the number of new patients, treatment adherence, hospitalizations, and deaths during the "pandemic period" (March 2020 to February 2021), the "pre-pandemic period" (the equivalent time frame in 2019), and the "post-pandemic period" (March to September 2021).

Decalogue to promote the implementation and improvement of recommendations for the early diagnosis of HIV in Emergency Departments.

Early diagnosis of HIV is still a challenge. Emergency Departments (EDs) suppose ideal settings for the early detection of HIV, since patients with high prevalence of hidden HIV infection are frequently attending those services. In 2020, the Spanish Society of Emergency and Emergency Medicine (SEMES) published a series of recommendations for the early diagnosis of patients with suspected HIV infection and their referral and follow-up in the EDs as part of its "Deja tu huella" program.

Effectiveness and tolerability of dolutegravir/lamivudine for the treatment of HIV-1 infection in clinical practice.

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.

HTLV-2 Enhances CD8 T Cell-Mediated HIV-1 Inhibition and Reduces HIV-1 Integrated Proviral Load in People Living with HIV-1.

People living with HIV-1 and HTLV-2 concomitantly show slower CD4 T cell depletion and AIDS progression, more frequency of the natural control of HIV-1, and lower mortality rates. A similar beneficial effect of this infection has been reported on HCV coinfection reducing transaminases, increasing the spontaneous clearance of HCV infection and delaying the development of hepatic fibrosis. Given the critical role of CD8 T cells in controlling HIV-1 infection, we analysed the role of CD8 T cell-mediated cytotoxic activity in coinfected individuals living with HIV-1.

The Negative Impact of COVID-19 in HCV, HIV, and HPV Surveillance Programs During the Different Pandemic Waves.

Background: The coronavirus disease 2019 (COVID-19) pandemic has been a worldwide stress test for health systems. 2 years have elapsed since the description of the first cases of pneumonia of unknown origin. This study quantifies the impact of COVID-19 in the screening program of chronic viral infections such as human papillomavirus (HPV), human immunodeficiency virus (HIV), and hepatitis C virus (HCV) along the six different pandemic waves in our population.

An Easy-to-Implement Risk Score for Targeted Hepatitis C Virus Testing in the General Population.

Despite the effectiveness of available treatments, hepatitis C virus (HCV) remains a major public health problem, mainly due to the high percentage of undiagnosed individuals. We aim to create an easy-to-implement risk score to facilitate targeted HCV testing in the general population. This is a substudy derived from a prospective study in primary care in Madrid (Spain).

Implementation of a lung cancer screening initiative in HIV-infected subjects.

In this pilot program of low-dose computed tomography (LDCT) for the screening of lung cancer (LC) in a targeted population of people with HIV (PWH), its prevalence was 3.6%; the number needed to screen in order to detect one case of lung cancer was 28, clearly outweighing the risks associated with lung cancer screening. While data from additional cohorts with longitudinal measurements are needed, PWH are a target population for lung cancer screening with LDCT.

Differences in epidemiology and mortality between men and women with HIV infection in the CoRIS cohort from 2004 to 2014.

Introduction: This study sought to analyse differences in epidemiology and survival between women and men living with HIV (WLHIV and MLHIV) in the CoRIS cohort and the course of their disease over a 10-year period.

Methods: Variables of interest between WLHIV and MLHIV were compared. A trend analysis was performed using the Mantel-Haenszel test.

Clinical and economic benefit of 32 years of antiretroviral treatment for people living with HIV in Spain: Has it been an efficient intervention?

Introduction: Although antiretroviral therapy (ART) for HIV/AIDS was introduced in 1987, improvement in disease progression and reduction in mortality at a population level was not observed until 1996, with the combination of three or more drugs. The objective was to estimate the clinical and economic benefit of ART in Spain in the 32-year period between 1987 and 2018.

Methods: A cost-benefit analysis was performed, using a second-order Monte Carlo simulation, from the societal (base case) and the National Health System (NHS) perspectives.

Antiretroviral treatment adherence and mental disorders: observational case-control study in people living with HIV in Spain.

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.
