RESUMO

INTRODUCTION: There is discussion about the frequency of STI screening among pre-exposure prophylaxis (PrEP) users. The aim of this study was to analyse the incidence of STIs and to evaluate different screening models in order to optimise the follow-up. METHODOLOGY: A prospective study was conducted between 2017 and 2023, including 138 PrEP users in a STI clinic. Participants were tested for STIs every three months. Unscheduled visits were performed for those with STI-related symptoms or for people who were notified for an STI by a sexual partner. We performed a survival analysis of repeated events, estimating the cumulative incidence (CI) and incidence rate (IR). RESULTS: The overall CI by quarterly screening was 8.3 (95% CI: 7.6-9.1) infections per person over six years, with a decreasing trend. The most frequently diagnosed pathogen was Neisseria gonorrhoeae, with a IR of 0.76 (95% CI: 0.68-0.84). If the frequency of screening is reduced to every six months, the IR of STIs is reduced by (95% CI: 0.5-0.66) infections per user per year, and at 12 months by 0.82 (95% CI: 0.73-0.89). In the case of no pharyngeal or urethral screening, IR is reduced by 0.37 (95% CI: 0.32-0.42) infections per person per year and in those over 35 years of age by 0.33 (95% CI: 0.25-0.4). Eliminating unscheduled visits, the reduction in IR is 0.33 (95% CI: 0.24-0.42). CONCLUSIONS: The incidence of STIs among PrEP users is high, especially in the rectum, but it does not increase over time. STI screening could be optimised reducing the frequency of pharyngeal and urethral testing, particularly in those over 35 years of age. It is essential to redistribute health resources for unscheduled visits, which have been shown to be the most cost-effective screening.

RESUMO

INTRODUCTION: We analyzed epidemiological, clinical characteristics, and the response to treatment in people living with HIV (PLHIV) who recently acquired hepatitis C (RAHC) in a multicentre study in Madrid (Spain). METHODS: Multicenter, ambispective, observational study of RAHC in men who have sex with men (MSM) infected with HIV. Clinical, epidemiological, and RAHC evolution were recorded prospectively in 2019 and 2020 and retrospectively in 2017 and 2018. In patients who received HCV treatment, sustained virological response (SVR) was provided 12 weeks after the end of treatment in an intention to treat analysis (ITT): all treated patients were included; and in analysis per-protocol (PP): missing patients were excluded. RESULTS: Overall, 133 patients were included. Median (IQR) age was 40 (34.3-46.1) years, 90.9% had at least one previous sexual transmission disease (STD), and 33.6% had previously hepatitis C. More than half of the prospective sample included patients using chemsex related drugs (57.3%), 45.7% of them intravenously. The most prevalent genotype was G1a (66.2%), followed by G4 (11.3%). Ten of 90 patients evaluated for spontaneous cure (11%) cured the infection spontaneously, and 119 had treatment after a median time of 1.8 (0.7-4.6) months: sustained virological response (SVR) was achieved in 90.7% in the ITT and 94.7% in the PP analysis, with no differences regarding the direct-acting antiviral agents (DAA) combination used. CONCLUSIONS: MSM infected by HIV with a RAHC were exposed to high-risk sexual behavior. Spontaneous cure rate was low, while SVR after treatment was achieved by more than 90%.

RESUMO

IntroducciónLa serología luética en la sífilis primaria puede ser negativa los primeros 5-15 días. El objetivo de este trabajo fue evaluar los beneficios de incluir la microscopia de campo oscuro (MCO) en el algoritmo diagnóstico de la sífilis primaria.MetodologíaSe incluyó a todos los pacientes que acudieron a una clínica de infecciones de transmisión sexual de la Comunidad de Madrid entre 2015 y 2019 que presentaban una úlcera genital sospechosa de sífilis primaria. Se les realizó MCO y serología (EIA/TPPA/RPR).ResultadosDe las 806 muestras, el 53,2% (429) fueron positivas para MCO. De los 429, el 48% presentaba screening serológico negativo (EIA/RPR) y de ellos en el 77,6% el TPPA fue positivo.ConclusionesLa MCO permite un diagnóstico de sífilis primaria precoz, incluso sin confirmación serológica. Si no se dispone de técnicas directas, en primoinfección, la TPPA es de gran ayuda en el diagnóstico.

RESUMO

IntroductionKnowing the factors associated with HIV transmission is necessary in order to design preventive programmes tailored to the epidemiological situation in each region and population.AimOur objective was to study the sociodemographic, clinical and behavioural characteristics of men who have sex with men (MSM) who were newly diagnosed with HIV infection.MethodsWe carried out an observational, descriptive, study on all MSM newly diagnosed with HIV infection in one clinic for sexually transmitted infections (STI) and HIV clinic in Madrid between 2014 and 2019. Information on sociodemographic, clinical, and behavioural characteristics of participants per year of diagnosis was collected.ResultsWe detected a total of 1,398 people with HIV infection, 253 of whom were recent seroconverters (rSCV) with a median duration of documented seroconversion of 6 months. From the total, 97.9% infections were sexually transmitted and 2.1% involved injected drugs, i.e. slam practices. The average age was 32.9 years (range: 15.6-74.9), 51.8% were Spanish and 40% Latin American. These diagnoses decreased in Spanish people and increased in Latin Americans during the study period. Of the rSCV, 73.9% had condomless sex under the influence of drugs and 28.9% participated in chemsex sessions. Apps were used by 92.6% rSCV for sexual encounters and 70.4% of them attributed HIV transmission to their use.ConclusionsCombination of HIV prevention strategies, as pre-exposure prophylaxis, should be reinforced among young MSM, especially those born in Latin America, those who use drugs for sex, and those who use apps in search of sexual contacts.

RESUMO

OBJECTIVE: Since the recent introduction of preexposure prophylaxis (PrEP), several studies have reported a decrease in the use of condoms and a rise in STIs among users. This rise in risk behavior associated with the advent of PrEP is known as "risk compensation." The aim of this study is to measure clinical and behavioral changes associated with the introduction of PrEP by analyzing condom use for anal intercourse, number of sexual partners, sexualized drug use and STI incidence. METHODS: We performed a retrospective descriptive study of PrEP users followed every 3months over a 2-year period spanning 2017-2019 in a referral clinic specializing in STI/HIV in Madrid, Spain. One hundred ten men who have sex with men and transgender women underwent regular screening for STIs and hepatitis C virus (HCV) infection. Sociodemographic, clinical, and behavioral data were gathered for all subjects studied. RESULTS: The risk compensation observed in this study consisted primarily of a lower rate of condom use, while the number of sexual partners and recreational drug consumption remained stable. We observed a very high incidence of STIs in this sample, particularly rectal gonorrhea and chlamydia. The factors shown to be independently associated with the presence of an STI on multivariate analysis were age below 30 years and over 10 sexual partners/month. CONCLUSION: The incidence of STI acquisition was higher than expected, indicating a need for strategies to minimize this impact, particularly among younger individuals with a higher number of sexual partners.

RESUMO

INTRODUCTION: Adolescents have a higher incidence of sexually transmitted infections (STIs) than persons of older age groups. The WHO emphasises the need to adopt specific and comprehensive prevention programmes aimed at this age group. The objective of this work was to analyse the prevalence of HIV/STIs among adolescents and to identify the sociodemographic, clinical and behavioural markers associated with these infections, in order to promote specific preventive strategies. METHODOLOGY: Retrospective descriptive study of adolescents, aged 10-19 years, who were attended to for the first consultation between 2016 and 2018 in a reference STI clinic in Madrid. All adolescents were given a structured epidemiological questionnaire where information on sociodemographic, clinical and behavioural characteristics was collected. They were screened for human inmmunodeficiency virus (HIV) and other sexually transmitted infections (STIs). The processing and analysis of the data was done using the STATA 15.0 statistical package. RESULTS: The frequency of HIV/STIs detected among all adolescents was: gonorrhoea 21.7%, chlamydia 17.1%, syphilis 4.8% and HIV 2.4%. After conducting a multivariate analysis, the independent and statistically significant variables related to the presence of an STI were having first sexual relations at a young age and having a history of STIs. Latin American origin was just below the level of statistical significance (p = 0.066). DISCUSSION/CONCLUSIONS: Adolescents who begin sexual relations at an early age or those who have a history of HIV/STIs are at higher risk of acquiring STIs. Comprehensive prevention programmes aimed specifically at adolescents should be implemented, especially before the age of 13 years.

RESUMO

INTRODUCCIÓN: La profilaxis preexposición (PrEP) al VIH consiste en administrar fármacos antirretrovirales a personas negativas para el VIH con prácticas de riesgo. El objetivo del estudio fue describir las características de los serconvertores recientes al VIH para conocer el perfil de los candidatos a quienes proponer PrEP. MÉTODOS: Estudio descriptivo de todos los pacientes diagnosticados de VIH durante 2014, con serología negativa documentada en los 12 meses previos. Se pasó un cuestionario estructurado para conocer características sociodemográficas, conductuales y clínicas, y se realizó despistaje de otras ITS. RESULTADOS: El 98,4% de los 61 seroconvertores recientes eran hombres que tenían sexo con hombres, de 20 a 39 años (88,5%), con antecedentes de ITS (80,3%) y múltiples parejas con las que mantenían sexo sin preservativo (82,7%), bajo el efecto de drogas recreativas (87%). CONCLUSIONES: Evaluar el riesgo para el VIH de los pacientes seronegativos permite identificar a los candidatos idóneos a quienes proponer la PrEP


INTRODUCTION: HIV Pre-Exposure Prophylaxis (PrEP) consists of administering antiretroviral drugs to seronegative individuals with high risk practices. The aim of the study was to describe the characteristics of recent seroconverted HIV patients in order to determine the profile of the appropriate candidates for PrEP. METHODS: A descriptive study of all patients diagnosed with HIV infection in 2014, and who had achieved a documented negative serology over the previous 12 months. A specific form was completed to determine the sociodemographic, behavioural, and clinical features, with complementary tests being performed for other sexually transmitted infections. RESULTS: Almost all (98.4%) of the 61 recent seroconverted were men who have sex with men, and aged between 20 to 39 years (88.5%). They also had a background of sexually transmitted infections (80.3%), performed multiple and unprotected sexual practices (82.7%), and under the effect of recreational drugs (87%). CONCLUSIONS: The evaluation of the risk factors for HIV infection in seronegative patients should enable the appropriate candidates for PrEP to be identified

RESUMO

El presente documento intenta reflejar y actualizar las principales tareas y cometidos que un laboratorio de microbiología debería tener para realizar el diagnóstico y seguimiento de los pacientes infectados por el VIH. Se distribuye en 3 apartados: en el primero se trata el diagnóstico serológico, que en los últimos años ha sufrido una importante renovación, y en el que hemos procurado adecuarnos a las demandas diagnósticas y epidemiológicas actuales, para que desde los laboratorios podamos contribuir a no perder oportunidades de diagnóstico. En una segunda parte se describe la determinación de la carga viral plasmática, y se hace una exhaustiva revisión de los avances tecnológicos y de las recomendaciones actuales, además de abordar un tema de enorme interés clínico, la significación de la viremia persistente de bajo grado. Finalmente, en el tercer apartado se desarrolla el tema de las resistencias a los fármacos antirretrovirales tanto en pacientesnaive como en fracaso, analizando la transcriptasa reversa, la proteasa y la integrasa, e incorporando como novedades las técnicas de determinación del tropismo viral, y el papel de las variantes minoritarias


This document attempts to update the main tasks and roles of the Clinical Microbiology laboratory in HIV diagnosis and monitoring. The document is divided into three parts. The first deals with HIV diagnosis and how serological testing has changed in the last few years, aiming to improve diagnosis and to minimize missed opportunities for diagnosis. Technological improvements for HIV Viral Load are shown in the second part of the document, which also includes a detailed description of the clinical significance of low-level and very low-level viremia. Finally, the third part of the document deals with resistance to antiretroviral drugs, incorporating clinical indications for integrase and tropism testing, as well as the latest knowledge on minority variants

RESUMO

BACKGROUND: As Lens epithelium-derived growth factor (LEDGF/p75) is an important co-factor involved in HIV-1 integration, the LEDGF/p75-IN interaction is a promising target for the new class of allosteric HIV integrase inhibitors (LEDGINs). Few data are available on the genetic variability of LEDGF/p75 and the influence on HIV disease in vivo. This study evaluated the relation between LEDGF/p75 genetic variation, mRNA expression and HIV-1 disease progression in order to guide future clinical use of LEDGINs. METHODS: Samples were derived from a therapy-naïve cohort at Ghent University Hospital and a Spanish long-term-non-progressor cohort. High-resolution melting curve analysis and Sanger sequencing were used to identify all single nucleotide polymorphisms (SNPs) in the coding region, flanking intronic regions and full 3'UTR of LEDGF/p75. In addition, two intronic tagSNPs were screened based on previous indication of influencing HIV disease. LEDGF/p75 mRNA was quantified in patient peripheral blood mononuclear cells (PBMC) using RT-qPCR. RESULTS: 325 samples were investigated from patients of Caucasian (n = 291) and African (n = 34) origin, including Elite (n = 49) and Viremic controllers (n = 62). 21 SNPs were identified, comprising five in the coding region and 16 in the non-coding regions and 3'UTR. The variants in the coding region were infrequent and had no major impact on protein structure according to SIFT and PolyPhen score. One intronic SNP (rs2737828) was significantly under-represented in Caucasian patients (P<0.0001) compared to healthy controls (HapMap). Two SNPs showed a non-significant trend towards association with slower disease progression but not with LEDGF/p75 expression. The observed variation in LEDGF/p75 expression was not correlated with disease progression. CONCLUSIONS: LEDGF/p75 is a highly conserved protein. Two non-coding polymorphisms were identified indicating a correlation with disease outcome, but further research is needed to clarify phenotypic impact. The conserved coding region and the observed variation in LEDGF/p75 expression are important characteristics for clinical use of LEDGINs.

RESUMO

Two HIV infected patients not receiving Highly Active Antiretroviral Treatment (HAART) presented with epidemic Kaposi's sarcoma of the oral cavity. One patient initially refused HAART, but when the lesion became large enough to be noticeable he agreed to HAART associated with excision of the intraoral lesion by CO2 laser. The other patient developed KS and progressed to AIDS at two years after ceasing HAART due to adverse effects; he was referred to hospital for renewed administration of HAART. In both cases, the lesions observed in the oral cavity were the first clinical manifestation of AIDS. These reports underline the close relationship between the use of HAART and the control of KS lesions, highlighting the important role of the dentist in the identification and early diagnosis of these oral lesions.

RESUMO

La poliquistosis renal autosómica dominante afecta al 5%-10% de personas en programa de hemodiálisis o de trasplante renal. Este estudio tiene un doble objetivo: conocer el perfil clínico del paciente con poliquistosis renal y comprender cómo esta enfermedad influye en las diferentes etapas vitales. El diseño de investigación es cuantitativo y cualitativo para dar respuesta a cada uno de los objetivos propuestos. La perspectiva cuantitativa abarca un estudio descriptivo retrospectivo de revisión de las historias clínicas de los pacientes atendidos en nuestro centro con este diagnóstico entre los años 2000 y 2005 (N=161). Para abarcar aspectos cualitativos de la enfermedad se han realizado dos entrevistas en profundidad, semiestructuradas, a personas cuyo diagnóstico ha actuado como condicionante en la toma de decisiones personales y familiares. El perfil de paciente con poliquistosis renal es el de una persona de 58 años de media con poliquistosis hepática, así como antecedentes familiares de la enfermedad y diversas patologías asociadas, siendo la más frecuente la hipertensión arterial. Las entrevistas en profundidad denotan la presencia de dolor crónico, con una alteración de la vida cotidiana y de la dinámica familiar. La incerteza en cuanto a su evolución y tratamiento produce ansiedad y un desgaste emocional progresivo (AU)


Autosomic dominant renal polycystosis affects 5%-10% of people on haemodialysis or with kidney transplants. This study has a two-fold purpose: to determine the clinical profile of the patient with renal polycystosis and to understand how this disease affects different vital stages. The research design is quantitative and qualitative in order to meet each of the proposed goals. The quantitative perspective encompasses a retrospective descriptive review of the case histories of the patients treated at our centre with this diagnosis between the years 2000 and 2005 (N=161). To cover qualitative aspects of the disease, two in-depth, semi-structured interviews were carried out with people whose diagnosis has acted as a conditioning factor in personal and family decision-making. The profile of the patient with renal polycystosis is that of person with an average age of 58 years with liver polycystosis, and with a family history of the disease and several associated pathologies, the most frequent being hypertension. The in-depth interviews denote the presence of chronic pain, with an alteration of daily life and family dynamics. The uncertainty as to its evolution and treatment produces anxiety and progressive emotional wear (AU)

RESUMO

Los pacientes sometidos a un trasplante renal están expuestos a una alteración en el metabolismo de los glúcidos, que puede ocasionar un tipo de diabetes conocida como esteroidea. El uso de corticoides, hormonas esteroideas, como tratamiento inmunosupresor para evitar el rechazo, parece ser el principal causante de la aparición de esta enfermedad en el trasplantado renal. En nuestro trabajo hemos querido estudiar, además de la influencia de estos fármacos, diversos factores predisponentes que puedan influir en la incidencia de la enfermedad: edad, sexo, índice de masa corporal y tratamiento sustitutivo previo al trasplante, tratamiento inmunosupresor utilizado, tiempo de aparición de la enfermedad post trasplante, etc. Los criterios de inclusión del estudio fueron: ser pacientes trasplantados renales entre septiembre de 1980 y octubre del 2000 en nuestro centro y no padecer ningún tipo de diabetes previa al injerto. Analizamos 39 casos de diabetes esteroidea de un total de 744 trasplantes realizados. La incidencia de la enfermedad fue del 5,2 por ciento. Se observó una relación entre la administración de corticoides a dosis altas (bolus de corticoides) como tratamiento inmunosupresor y la aparición de la enfermedad (79 por ciento, 31 casos). La edad también condicionó la aparición de la misma, pues el 85 por ciento (33 casos) de los pacientes tenían más de 40 años en el momento de realizarse el trasplante (AU)
