Rapid expansion of lymphogranuloma venereum infections with fast diversification and spread of L genovariants.

Numerous international organizations, including the World Health Organization, have been drawing attention to the global increase in sexually transmitted infections. Twenty years ago, lymphogranuloma venereum (LGV) was mainly considered a tropical disease; in recent decades, however, LGV has been increasingly present in high-income countries. This increase has been linked to men who have sex with men who participate in highly interconnected sexual networks, leading to a rapid spread of LGV.

Monitoring monkeypox virus in saliva and air samples in Spain: a cross-sectional study.

Background: The transmission of monkeypox virus occurs through direct contact, but transmission through saliva or exhaled droplets and aerosols has not yet been investigated. We aimed to assess the presence of monkeypox virus DNA and infectious virus in saliva samples and droplets and aerosols exhaled from patients infected with monkeypox virus.

Methods: We did a cross-sectional study in patients with monkeypox confirmed by PCR who attended two health centres in Madrid, Spain.

Elite controllers long-term non progressors present improved survival and slower disease progression.

Different phenotypes exhibiting no evidences of disease progression have been described in ART-naïve HIV-1 positive individuals. Long-term non progressors (LTNP) and elite controllers (EC) are low frequent examples of immunological and virological control in HIV-1 positive subjects, respectively. The combination of both phenotypes is even less frequent and studied despite being considered as models of HIV-1 functional cure.

Monkeypox outbreak in Madrid (Spain): Clinical and virological aspects.

Background: Monkeypox is the most prevalent Orthopoxvirus zoonosis infection since the eradication of smallpox. The current multi-country outbreak involves five WHO regions affecting mainly Europe. Accurate clinical and virological aspects of the disease outside endemic areas are needed.

Immunoescape of HIV-1 in Env-EL9 CD8 + T cell response restricted by HLA-B*14:02 in a Non progressor who lost twenty-seven years of HIV-1 control.

Background: Long-Term Non-Progressors (LTNPs) are untreated Human Immunodeficiency virus type 1 (HIV-1) infected individuals able to control disease progression for prolonged periods. However, the LTNPs status is temporary, as viral load increases followed by decreases in CD4 + T-cell counts. Control of HIV-1 infection in LTNPs viremic controllers, have been associated with effective immunodominant HIV-1 Gag-CD8 + T-cell responses restricted by protective HLA-B alleles.

rs7041 and rs3829251 are Linked to CD4 Recovery in HIV Patients on Antiretroviral Therapy.

The lack of the recovery of CD4 T-cells (CD4 recovery) among immunodeficiency virus (HIV)-infected patients on antiretroviral therapy (ART) is not well known. We aimed to analyze the association between single nucleotide polymorphisms (SNPs) underlying vitamin D metabolism and the CD4 recovery in naïve HIV-infected patients who started ART with low baseline CD4. We conducted a retrospective study in 411 naïve individuals with plasma HIV load >200 copies/mL and CD4 <200 cells/mm.

Identification of CRF66_BF, a New HIV-1 Circulating Recombinant Form of South American Origin.

Circulating recombinant forms (CRFs) are important components of the HIV-1 pandemic. Among 110 reported in the literature, 17 are BF1 intersubtype recombinant, most of which are of South American origin. Among these, all 5 identified in the Southern Cone and neighboring countries, except Brazil, derive from a common recombinant ancestor related to CRF12_BF, which circulates widely in Argentina, as deduced from coincident breakpoints and clustering in phylogenetic trees.

Comparison of Polydrug Use Prevalences and Typologies between Men Who Have Sex with Men and General Population Men, in Madrid and Barcelona.

This study compares the prevalence of drug use and the typologies of polydrug use (PDU) in men who have sex with men (MSM) and general population men (GPM). Participants were men aged 16-64, living in the provinces of Madrid and Barcelona: 1720 were recruited in a GPM survey, and 2658 were HIV-negative MSM from HIV/STIs diagnosis services. Lifetime and last-year prevalence of drug use and prevalence ratios (PRs) of MSM to GPM for the different drugs were calculated using Poisson regression.

Sexualized drug injection among men who have sex with men in Madrid and Barcelona as the first episode of drug injecting.

Background: We estimate the prevalence of drug injection, the variables associated with having ever injected and the proportion of ever injectors whose first drug injection was for having sex; we describe the first drug injection episode, analyze the drugs most frequently injected and estimate the prevalence of risky injecting behaviors.

Methods: The participants were 3387 MSM without a previous HIV diagnosis attending four HIV/STI diagnosis services in Madrid and Barcelona. Lifetime prevalence and prevalence ratios (PRs) by different factors were calculated using Poisson regression models with robust variance.

Preventive Efficacy of Tenofovir/Emtricitabine Against Severe Acute Respiratory Syndrome Coronavirus 2 Among Pre-Exposure Prophylaxis Users.

Background: The preventive effect that tenofovir/emtricitabine (FTC) could have against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in human immunodeficiency virus-negative people is unknown. The objective of this study was to analyze the seroprevalence and clinical manifestations of COVID-19 among users of pre-exposure prophylaxis (PrEP), disoproxil fumarate/FTC (TDF/FTC), or tenofovir alafenamide (TAF)/FTC and to compare it to that of a control group.

Methods: An observational descriptive study of the seroprevalence of antibodies for SARS-CoV-2 among men who have sex with men and transgender women without use of PrEP (Group 1; n = 250) and PrEP users with TDF/FTC (n = 409) or TAF/FTC (n = 91) (Group 2; n = 500) was conducted from May11, 2020 to June 27, 2020.

Psychological distress in women and men living with HIV in Spain: a cross-sectional telephone survey.

Background: Psychological distress includes a broader range of experiences, varying from less severe symptoms of depression and anxiety to severe psychiatric disease. Global estimates for depression and anxiety in 2017 were 3.4% and 3.

Health care issues affecting transgender people living with HIV: an opportunity for improvement.

The high vulnerability of transgender (TG) persons to HIV infection and the difficulties associated with access to health services can lead to delays in the diagnosis and treatment of HIV infection, thus increasing the risk of transmission of HIV by this population. We performed a retrospective study to analyze the main characteristics of TG living with HIV infection in a hospital in Madrid, Spain and to identify issues related to lack of access to the health care system and combination antiretroviral therapy (cART). We analyzed 28 TG, of whom 22 (78.

Soluble PD-L1: a potential immune marker for HIV-1 infection and virological failure.

Despite viral control, basal chronic inflammation and its related comorbidities remain unsolved problems among HIV-infected individuals. Soluble factors derived from myeloid cells have emerged as potent markers associated with HIV-related comorbidities and mortality. In the present report, we explored the relationship between soluble programmed death-ligand 1 (sPD-L1) and HIV-1 infection, antiretroviral therapy (ART), CD4/CD8 ratio, viral load (VL), and sexually transmitted coinfections.

Permanent control of HIV-1 pathogenesis in exceptional elite controllers: a model of spontaneous cure.

Elite controllers (EC) represent a small subset of HIV-1-infected people that spontaneously control viral replication. However, natural virological suppression and absence of immune dysfunction are not always long-term sustained. We define exceptional EC (EEC) as HIV-1 subjects who maintain the EC characteristics without disease progression for more than 25 years.

Tolerability of IM penicillin G benzathine diluted or not with local anesthetics, or different gauge needles for syphilis treatment: a randomized clinical trial.

Background: Penicillin G Benzathine (PGB) is the cornerstone of syphilis treatment. However, its intramuscular (IM) administration is associated with pain at the site of injection. The dilution of PGB with local anesthetics is recommended in some guidelines, but the evidence that supports it, particularly in adults and in HIV infection, is scarce.

Natural Conception is Safe for HIV-Serodiscordant Couples with Persistent Suppressive Antiretroviral Therapy for the Infected Partner.

Sustained use of antiretroviral treatment to achieve a suppressed viral load in persons living with HIV is associated with zero or near-zero risk of sexual and vertical HIV transmission. This has led to an increasing number of HIV-serodiscordant couples (SDCs) who wish to have children. The aim of this study was to describe the most recent results of a protocol for reproductive counseling directed at HIV-SDCs who desire natural conception and to identify some of the factors influencing reproductive success.

Durability of first-line antiretroviral regimens in the era of integrase inhibitors: a cohort of HIV-positive individuals in Spain, 2014-2015.

Background: We compared time to treatment change (TC), viral suppression (VS) and change in CD4 T-cell counts of first-line antiretroviral regimens (ART).

Methods: We analysed HIV treatment-naive adults from the Cohort of the Spanish HIV/AIDS Research Network (CoRIS) initiating the most commonly used ART regimens from September 2014 to November 2015. We used proportional hazards models on the sub-distribution hazard to estimate sub-distribution hazard ratios (sHR) for time to TC, logistic regression to estimate odds ratios (ORs) for VS (viral load <50 copies/ml), and linear regression to assess mean differences in CD4 T-cell changes from ART initiation.

A high mucosal blocking score is associated with HIV protection.

Background: Early steps of HIV infection are mediated by the binding of the envelope to mucosal receptors as α4β7 and the C-type lectins DC-SIGN and langerin. Previously Env-specific B-cell responses have been reported in highly exposed seronegative individuals (HESN).

Method: Here, we studied gp120-specific antibodies ability to block HIV interaction with α4β7, DC-SIGN and/or langerinin HESN.
