Introduction: People living with human immunodeficiency virus (PLHIV) may suffer more severe symptoms of coronavirus disease 2019 (COVID-19) due to their immunocompromised status, even if they are undetectable. Human immunodeficiency virus (HIV) infection has been reported as an independent factor associated with higher mortality in patients with COVID-19. The present study aims to describe the clinical characteristics of PLHIV and COVID-19 in one center in Mexico. Methodology: We conducted an observational retrospective monocentric cohort study of PLHIV diagnosed with COVID-19 between 1 March 2020 and 30 April 2021. SARS-CoV-2 was detected by polymerase chain reaction (PCR) of a nasopharyngeal swab sample, clinical features, and epidemiological characteristics. Results: We identified 55 PLHIV with COVID-19. The median age was 36 years (IQR 25-41.5 years), and 54 patients were men. The median duration of HIV-1 infection was 4.3 years (Interquartile range, IQR 2.6-7.2 years), and 100% were on antiretroviral therapy (ART). The last HIV-1 RNA viral load analysis of the patients was 52/55 (94.5%) indicating that they were in virological suppression. The median CD4+ Tcell count was 734/mm³ (IQR 541.5-921/mm³). The most frequent pre-existing comorbidities found were obesity (21.8%), hypertension (7.2%), and diabetes (5.4%). Only one death was reported (1.8%). Conclusions: It has been reported that COVID-19/HIV/AIDS co-infection has a higher risk of mortality, admission to intensive care, and complications. However, our study found that people living with HIV-1 with adequate virological control did not present a severe course of COVID -19. [ABSTRACT FROM AUTHOR]

Purpose: In the last two decades transmission of hepatitis C virus (HCV) in HIV positive men who have sex with men (MSM) has been reported globally. Chemsex and specific sexual practices have been identified as risk factors. Our study aimed to identify risk factors for HCV transmission in MSM living with HIV attending in Mexico. Methods: We conducted a case-control study from April to December 2019 at the Hospital de Infectología "La Raza" National Medical Center, in Mexico City. A case was defined as an HIV-infected MSM with positive HCV-antibody test. For each case, 3 controls were included, defined as HIV infected MSM with negative HCV-antibody test. A self-questionnaire covering sexual practices and other risk factors for HCV transmission was applied. Bivariate analysis was performed to obtain odds ratio (OR) using Chi-square test. Independent risk factors were identified in a subsequent analysis performing a logistic regression model. Results: A total of 324 patients participated in the study, 81 cases and 243 controls. Median age was 30.5 years (IQR: 18–52) and 28.8 years (IQR: 21–45) in the case and control group, respectively. Most prevalent HCV genotype was 1a (79%). In the logistic regression model, sharing straw during cocaine inhalation (OR: 9.03; 95% CI; 1.35–13.52; P = 0.003), sharing sex toys (OR: 17.53, 95% CI; 6.85–44.86; P = 0.002), and ethyl chloride use for chemsex (OR: 2.26; 95% CI; 1.29–5.56; P = 0.037) were significant risk factors for HCV infection. Conclusion: This study identifies risk factors for HCV transmission in Mexico in HIV positive MSM in congruence with the findings of many studies performed worldwide. This is the first study that indicates a possible association between ethyl chloride use in chemsex and HCV infection. Assessment of local populations for risk factors for HCV transmission may help to develop specifically targeted behavioral interventions to reduce HCV transmission. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Congenital syphilis (CS) remains a major public health problem, and its incidence is increasing worldwide., Methods: Retrospective, observational, and descriptive study of cases with CS and their mothers at a tertiary-level hospital in Mexico from 2017 to 2022. Medical records of patients with CS and a structured collection of epidemiological, clinical, and laboratory data were analyzed and classified in the Centers for Disease Control scenarios as confirmed, probable, less probable, or unlikely., Results: One hundred eighty cases were diagnosed with a compatible definition of congenital syphilis, and we identified 43 (21.21%) confirmed proven. Among those proven cases, 15.6% had hematological, 13.3% skin, 12.2% liver, 6.7% pulmonary, 6.6% neurological, 5.8% eye, 5.6% bone, and 0.6% hearing involvements. According to the clinical stages of maternal syphilis, 119 (66.1%) were in the late latent phase, 49 (27.2%) in the early latent phase, 7 (3.9%) in the secondary stage, and 5 (2.8%) in the primary stage. Mothers with tertiary syphilis were not detected., Conclusion: Regardless of negative antenatal screening, health care workers should consider the diagnosis of congenital syphilis. Infants are still undiagnosed at birth, and only a tiny percentage exhibits symptoms. The wide range of clinical manifestations of this preventable infection can be misdiagnosed for various other diseases, causing diagnostic delays that can have serious consequences., Competing Interests: Conflict of Interest and Sources of Funding: None declared., (Copyright © 2023 American Sexually Transmitted Diseases Association.

- Abstract
On 13 May 2022, a familial cluster of two cases of monkeypox was reported in the United Kingdom (UK) by the UK Health Security Agency (UKHSA). These cases had no relation to a case imported from Nigeria that was previously reported on 7 May 2022 in the UK. In the following days, several other European Union (EU) the Member States and other countries have reported cases of monkeypox not linked to travel to endemic countries. The report by the World Health Organization (WHO) until May 26, 2022, is of a total of 257 confirmed cases and 120 suspected cases, without any report of death. This outbreak involves 23 countries that are not endemic to the monkeypox virus. Latin America had no reported cases. We describe a case of imported monkeypox in Mexico City, Mexico., Competing Interests: Conflict of Interest All authors report no conflicts of interest with this article., (Copyright © 2022.

- Abstract
Objective: To investigate the impact of single nucleotide polymorphisms (SNPs) from APOA5, APOC3, CETP, ATP binding cassette transporter A1 and SIK3 genes in the development of hypertriglyceridemia in HIV patients under antiretroviral therapy., Material and Methods: A case-control study was developed. Leukocytic genomic DNA was extracted and genotyping for SNPs rs662799, rs964184, rs5128, rs2854116, rs2854117, rs3764261, rs4149310, rs4149267 and rs139961185 was performed by real time-PCR using TaqMan allelic discrimination assays, in Mexican mestizo patients with HIV infection, with hypertriglyceridemia (>1.7 mmol/L) under antiretroviral therapy. Genetic variants were also investigated in a control group of normolipidemic HIV patients (≤ 1.7 mmol/L). Haplotypes and gene interactions were analyzed., Results: A total of 602 HIV patients were genotyped (316 cases and 286 controls). Age and antiretroviral regimen based on protease inhibitors were associated with hypertriglyceridemia (P = 0.0001 and P = 0.0002. respectively). SNP rs964184 GG genotype in APOA5 gene exhibited the highest association with hypertriglyceridemia risk (OR, 3.2, 95% CI, 1.7-5.8, P = 0.0001); followed by SNP rs139961185 in SIK3 gene (OR = 2.3; (95% CI, 1.1-4.8; P = 0.03 for AA vs. AG genotype; and APOC3 rs5128 GG genotype, (OR, 2.2; 95% CI, 1.1-4.9; P = 0.04) under codominant models. These associations were maintained in the adjusted analysis by age and protease inhibitors based antiretroviral regimens., Conclusions: This study reveals an association between rs964184 in APOA5; rs5128 in APOC3 and rs139961185 in SIK3 and high triglyceride concentrations in Mexican HIV-patients receiving protease inhibitors. These genetic factors may influence the adverse effects related to antiretroviral therapy., (Copyright © 2021 Wolters Kluwer Health, Inc. All rights reserved.)
