RESUMO

Introducción: La profilaxis preexposición (PrEP) es una intervención biomédica dirigida a prevenir la infección por el VIH en personas seronegativas con alto riesgo de contraer la infección. Esta estrategia fue aprobada por el Ministerio de Salud de España en octubre de 2019. Objetivo: Presentar la experiencia inicial de la PrEP en la Unidad de VIH del Hospital Clínic de Barcelona, poniendo especial atención en el análisis de los factores de vulnerabilidad de la cohorte. Materiales y métodos: Estudio retrospectivo, descriptivo. Se analizan las características epidemiológicas, sociodemográficas y clínicas basales de los usuarios incluidos en el programa durante el primer año de funcionamiento, prestando particular atención a las infecciones, las prácticas de riesgo y el consumo de sustancias. Resultados: Se incluyeron 190 individuos, 177 hombres y 12 mujeres transexuales con una edad media de 35 años (8DE). El 70% tenía estudios superiores y la mitad nacionalidad española. Informaron de tener 10 parejas de media al trimestre y el 60% de practicar sexo anal desprotegido. El 31% presentó al menos una PCR positiva para ITS, siendo la N. gonorrhoeae el germen más prevalente (51%) y la muestra rectal la más afectada (21%). El 63% reportó el uso de chemsex, el 19% policonsumo y el 8% slamming. La mitad expresó su preocupación por el consumo y/o prácticas sexuales y un 25% la necesidad de ayuda. Conclusiones: El perfil del usuario de PrEP visitado en nuestra unidad hospitalaria justifica la creación de equipos multidisciplinares que permitan prestar una atención holística de la vida sexual de estas personas.(AU)


Introduction: Pre-Exposure Prophylaxis (PrEP) is a biomedical intervention to prevent HIV infection in seronegative people at high risk of becoming infected. This strategy was endorsed in October 2019 by the Spanish Ministry of Health. Objective: To present the PrEP initial experience in the HIV Unit of the Hospital Clínic of Barcelona, paying special attention to the analysis of the vulnerability factors in the cohort. Materials and methods: Retrospective, descriptive study. The epidemiological, sociodemographic, and clinical characteristics of the users included in the program during the first year are analyzed, paying particular attention to Infections, risky practices, and substance use. Results: 190 individuals were included, 177 men and 12 trans women with a mean age of 35 years (8 SD). 70% had higher education, and half had Spanish nationality. An average of 10 couples per trimester and 60% reported unprotected anal sex. 31% had at least one positive PCR for STIs, with N. gonorrhoeae being the most prevalent microorganism (51%) and the rectal sample the most affected (21%). 63% reported chemsex use, 19% polydrug use, and 8% “slamming”. Half expressed concern about consumption and/or sexual practices and 25% the need for help. Conclusions: The PrEP user profile attended in our Hospital Unit justifies the creation of multidisciplinary teams that allow us to provide holistic attention to the sexual life of these people.(AU)

RESUMO

OBJECTIVE: Hepatitis C virus (HCV) therapy with direct-acting antivirals (DAA) achieves high rates of sustained virological response in people living with human immunodeficiency virus (HIV) (PLWH). Information on its long-term clinical impact is scarce. The aim of this study was to analyse liver fibrosis and immune response evolution after DAA treatment. METHODS: Retrospective, single centre cohort study of HIV-HCV co-infected patients treated with DAA between June 2013 and June 2018. We analysed the changes during follow up in liver fibrosis (assessed by transient elastography (TE), aspartate aminotransferase to platelet ratio index (APRI) and FIB-4 scores) and immunity (CD4 and CD8 cells counts and CD4/CD8 ratio). RESULTS: We included 410 patients; 75% (308/407) men with a mean age of 50 years (SD 8); 78% (318/410) had long chronic HCV infection (median 21 years, interquartile range (IQR) 6-27 years) and 27% (107/393) had liver cirrhosis. Liver fibrosis improvement based on the decrease in TE value compared with the baseline occurred in 43% (131/302) of patients and 31% of patients based on biological scores (APRI: 124/398; FIB-4: 104/398) (p < 0.0001), being more frequent in those with advanced baseline fibrosis (83/144). The higher decrease was observed at 6 months after DAA therapy (-0.23; 95% CI -0.29 to -0.18), but a continuum in fibrosis regression of at least 30% from baseline value of TE was observed along the follow up (32% of patients at month 6, 51% at month 24 and 55% at month 48). Regarding the immunological profile, there was a significant decrease in CD8 counts at month 48 (-62.38; 95% CI -106.77 to -17.99; p 0.0001) and a progressive rise in the CD4/CD8 ratio after 24 months of follow up reaching an increment of +0.07 (95% CI 0.03-0.10, p 0.0001) at month 48. CONCLUSIONS: HCV treatment with DAA in PLWH is associated with significant progressive improvement in liver fibrosis and recovery of the immune system with an increase in the CD4/CD8 ratio in long-term follow up.

RESUMO

Background: Acute hepatitis C virus (AHC) infection is increasingly common among HIV+ men who have sex with men (MSM). Until 2017, the guidelines recommended therapy with pegylated-interferon plus ribavirin with a mild sustained virological response (SVR). This prompted many patients to reject that treatment, at that time, waiting to be treated with better and safer options with new Direct-Acting-Antivirals (DAA). Objectives: Assess the efficacy and safety of Elbasvir/Grazoprevir to treat recent chronic hepatitis C infection, genotype 1 or 4, in HIV+ MSM patients. Methods: Prospective, open-labeled, two center, pilot study. SVR is analyzed for treatment with Elbasvir/Grazoprevir (8 weeks in GT1b or 12 in GT1a or GT4) in patients with a recent chronic HCV infection, defined as HCV infection lasting less than 4 years and mild liver fibrosis (liver stiffness <8kPa). Results: Forty-eight patients were included (May 2017–March 2018): 2 GT1b, 24 GT1a and 22 GT4. HCV-RNA>800000UI in 63% and medium liver stiffness 4.9kPa. The SVR was 98%, one patient failed due to poor adherence. 67% of patients had adverse effects, but only 16% treatment related. The most frequent side effects were gastrointestinal (19%), related with the central nervous system (18%), respiratory (16%) and systemic symptoms (15%).During one year of follow-up post-therapy, 4 AHC and 18 patients with sexually transmitted diseases (STD) were diagnosed. Conclusions: Treatment with Elbasvir/Grazoprevir in this scenario is highly effective and safe. Patients with risky sexual practices must remain linked to the medical care system to detect new STD and HCV reinfection.(AU)


Antecedentes: La infección aguda por el virus de la hepatitis C (HCA) es cada vez más frecuente entre los hombres VIH+ que mantienen relaciones sexuales con hombres (HSH). Hasta 2017, las directrices recomendaban el tratamiento con interferón pegilado más ribavirina con una respuesta virológica sostenida (RVS) leve. Esto llevó a muchos pacientes a rechazar dicho tratamiento en ese momento, a la espera de recibir tratamiento con opciones mejores y más seguras con los nuevos antivirales de acción directa (AAD). Objetivos: Evaluar la eficacia y la seguridad de elbasvir/grazoprevir para tratar la infección por hepatitis C crónica reciente, genotipo 1 o 4, en pacientes HSH VIH+. Métodos: Estudio preliminar, prospectivo, abierto y realizado en 2 centros. Se evalúa la RVS para el tratamiento con elbasvir/grazoprevir (8 semanas en GT1b o 12 en GT1a o GT4) en pacientes con una infección por VHC crónica reciente, definida como una infección por VHC que dura menos de 4 años y fibrosis hepática leve (rigidez hepática <8kPa). Resultados: Se incluyeron 48 pacientes (mayo de 2017-marzo de 2018): 2 en GT1b, 24 en GT1a y 22 en GT4. ARN-VHC>800.000UI en el 63% y rigidez hepática media de 4,9Kpa. La RVS fue del 98%; un paciente fracasó debido a un cumplimiento terapéutico deficiente. El 67% de los pacientes presentó efectos adversos, pero solo el 16% estuvo relacionado con el tratamiento. Los efectos secundarios más frecuentes fueron síntomas gastrointestinales (19%), relacionados con el sistema nervioso central (18%), respiratorios (16%) y sistémicos (15%). Durante un año de seguimiento postratamiento se diagnosticaron 4 HCA y 18 pacientes con enfermedades de transmisión sexual (ETS). Conclusiones: El tratamiento con elbasvir/grazoprevir en este contexto es muy eficaz y seguro. Los pacientes con prácticas sexuales de riesgo deben permanecer vinculados al sistema de asistencia médica para detectar nuevas ETS y reinfecciones por VHC.(AU)
