A cascade of care for diabetes in people living with HIV in a tertiary care center in Mexico City.

Background: Diabetes affects 4.5% of people living with HIV in Mexico. This study aims to describe the diabetes cascade of care (DMC) in people with HIV in a tertiary center in Mexico City.

Adjuvant Topical Interferon Alpha 2b for the Treatment of Monkeypox Ocular Manifestations.

Purpose: The aim of this study was to report a case of ocular Mpox that responded favorably to treatment with topical interferon and oral doxycycline.

Methods: This is a case report of a previously healthy 24-year-old woman who developed a pustular rash, headache, fever, arthralgia, sore throat, and asthenia 3 weeks before attending to our clinic. Her main complaint at the moment of the visit was pain, photophobia, foreign body sensation, blurred vision, red eye, and discharge on the left eye.

Development and content validity of EVAD: A novel tool for evaluating and classifying the severity of adverse events for psychotherapeutic clinical trials.

Objective: Develop and obtain content validity of a new tool for Evaluating and Classifying the Severity of Adverse Events for Psychotherapeutic Clinical Trials (EVAD).

Method: Study of the development process of EVAD in four stages: (1) identify the domain and concept definition through a literature review, (2) instrument design, (3) expert judgment of the EVAD items through Gwent's concordance coefficient, and (4) applicability.

Results: In the absence of a consistent conceptual framework of adverse events in psychotherapeutic clinical trials, we have developed a framework and defined it.

Incomplete Antiretroviral Therapy Adherence Is Associated with Lower CD4-CD8 Ratio in Virally Suppressed Patients with HIV Infection in Mexico.

Suboptimal adherence to antiretroviral therapy (ART) in people with HIV, even during sustained viral suppression, is associated with persistent inflammation, immune activation, and coagulopathy. Persistently low CD4-CD8 Ratio has been also associated with residual inflammation, is a good predictor of increased risk of death and more widely available than inflammatory biomarkers. We tested the hypothesis that the CD4-CD8 Ratio is associated with ART adherence during periods of complete viral suppression.

Gaps in the continuum of care in HIV-positive adults and the need for caution in those returning to care after loss to follow-up.

Loss to follow-up (LTFU) and interruption of antiretroviral therapy (ART) are associated with worse outcomes in people with HIV (PWH). Little is known about gaps in the continuum of care. We conducted a retrospective cohort study including adult PWH with at least one clinical visit during 2000-2017.

Risk factors associated with HCV co-infection amongst MSM and transgender women living with HIV in Mexico City: A case-control study.

Introduction And Objectives: Hepatitis C virus infection (HCV) is a major cause of co-morbidity in people living with HIV (PLWHIV). The modes of HCV transmission in the local population of PLWHIV are still unclear. We conducted this study to identify risk factors for HCV transmission amongst PLWHIV in central Mexico.

Relationship Between Anemia and Systemic Inflammation in People Living With HIV and Tuberculosis: A Sub-Analysis of the CADIRIS Clinical Trial.

People with HIV (PWH) are at increased risk of developing active tuberculosis (TB), and anemia is a common complication in both conditions. Anemia in TB patients has been linked to immune activation, levels of inflammatory biomarkers in blood, and risk for HIV disease progression and death. In this study we show that anemia was associated with a more pronounced inflammatory profile in HIV-TB coinfected persons in a cohort of 159 individuals with advanced HIV disease (CD4 count < 100 cells/µL) recruited as part of a randomized clinical trial (NCT00988780).

Clinical effects of durability of immunosuppression in virologically suppressed ART-initiating persons with HIV in Latin America. A retrospective cohort study.

Background: Clinical outcomes are rarely studied in virologically suppressed people living with HIV (PWH) and incomplete CD4 recovery. To explore whether time living with severe immunosuppression predict clinical outcomes better than baseline or time updated CD4, we estimated the association between cumulative percentage of time with CD4 <200 cells/μL during viral suppression (VS) (%t), and mortality and comorbidities during 2000-2019.

Methods: In a retrospective cohort analysis, we followed PWH initiating ART in Latin America from first VS (HIV-RNA<200 copies/μL) to death, virological failure or loss to follow-up.

Seroepidemiology of SARS-CoV-2 in healthcare personnel working at the largest tertiary COVID-19 referral hospitals in Mexico City.

Introduction: We performed a longitudinal SARS-CoV-2 seroepidemiological study in healthcare personnel of the two largest tertiary COVID-19 referral hospitals in Mexico City.

Methods: All healthcare personnel, including staff physicians, physicians in training, nurses, laboratory technicians, researchers, students, housekeeping, maintenance, security, and administrative staff were invited to voluntarily participate, after written informed consent. Participants answered a computer-assisted self-administered interview and donated blood samples for antibody testing every three weeks from October 2020 to June 2021.

Retention in Care, Mortality, Loss-to-Follow-Up, and Viral Suppression among Antiretroviral Treatment-Naïve and Experienced Persons Participating in a Nationally Representative HIV Pre-Treatment Drug Resistance Survey in Mexico.

We describe associations of pretreatment drug resistance (PDR) with clinical outcomes such as remaining in care, loss to follow-up (LTFU), viral suppression, and death in Mexico, in real-life clinical settings. We analyzed clinical outcomes after a two-year follow up period in participants of a large 2017-2018 nationally representative PDR survey cross-referenced with information of the national ministry of health HIV database. Participants were stratified according to prior ART exposure and presence of efavirenz/nevirapine PDR.

Exceptional T CD4 Recovery Post-antiretroviral Is Linked to a Lower HIV Reservoir with a Specific Immune Differentiation Pattern.

We present a cohort of individuals who reached CD4 T cell counts of greater than 1,000 cells/mm (Hypers) after starting antiretroviral treatment (ART) and compared them with those who reached between 350 and 999 CD4 T cells/mm (Concordants). Demographic data, immune recovery kinetics, T CD4 subset phenotypes, and integrated HIV DNA were analyzed. Data from individuals living with HIV on their first ART regimen and after 48 months of follow-up were obtained.

CLINICAL AND EPIDEMIOLOGICAL CHARACTERISTICS OF PATIENTS DIAGNOSED WITH COVID-19 IN A TERTIARY CARE CENTER IN MEXICO CITY: A PROSPECTIVE COHORT STUDY.

Background: Regional information regarding the characteristics of patients with coronavirus disease (COVID)-19 is needed for a better understanding of the pandemic.

Objective: The objective of the study to describe the clinical features of COVID-19 patients diagnosed in a tertiary-care center in Mexico City and to assess differences according to the treatment setting (ambulatory vs. hospital) and to the need of intensive care (IC).

Frequency of non-communicable diseases in people 50 years of age and older receiving HIV care in Latin America.

Background: A growing population of older adults with HIV will increase demands on HIV-related healthcare. Nearly a quarter of people receiving care for HIV in Latin America are currently 50 years or older, yet little is known about the frequency of comorbidities in this population. We estimated the prevalence and incidence of non-communicable diseases (NCDs) among people 50 years of age or older (≥50yo) receiving HIV care during 2000-2015 in six centers affiliated with the Caribbean, Central and South American network for HIV epidemiology (CCASAnet).

High prevalent human papillomavirus infections of the oral cavity of asymptomatic HIV-positive men.

Background: Incidence of anal and oral infections with Human Papillomavirus (HPV) is increasing, particularly among Human Immunodeficiency Virus-positive (HIV+) men. HPV type 16 has exhibited the highest incidence and only limited data is available on other prevalent types, variants of HPV16, as well as associated factors. We were interested in identifying prevalent HPV types, variants of type 16, as well as factors associated with HPV16 infections in the oral cavity of HIV+ men who have sex with men (MSM).

The Population Impact of Late Presentation With Advanced HIV Disease and Delayed Antiretroviral Therapy in Adults Receiving HIV Care in Latin America.

Late presentation to care and antiretroviral therapy (ART) initiation with advanced human immunodeficiency virus (HIV) disease are common in Latin America. We estimated the impact of these conditions on mortality in the region. We included adults enrolled during 2001-2014 at HIV care clinics.

III. THE ROLE OF THE RESEARCH ETHICS COMMITTEES IN THE REGULATION OF PHARMA-SPONSORED STUDIES.

Participants of Pharma-sponsored research are exposed to risks, benefits, and uncertainties that do not occur in other forms of clinical studies. Ethics committees represent the subjects' first line of protection. This responsibility begins with the study review and ends after all study subjects finish the intervention.

Durability of Efavirenz Compared With Boosted Protease Inhibitor-Based Regimens in Antiretroviral-Naïve Patients in the Caribbean and Central and South America.

Background: Efavirenz (EFV) and boosted protease inhibitors (bPIs) are still the preferred options for firstline antiretroviral regimens (firstline ART) in Latin America and have comparable short-term efficacy. We assessed the long-term durability and outcomes of patients receiving EFV or bPIs as firstline ART in the Caribbean, Central and South America network for HIV epidemiology (CCASAnet).

Methods: We included ART-naïve, HIV-positive adults on EFV or bPIs as firstline ART in CCASAnet between 2000 and 2016.
