Situación epidemiológica de las infecciones de transmisión sexual pospandemia en Cataluña, España / Epidemiological situation of post-pandemic sexually transmitted infections in Catalonia, Spain

Antecedentes La creciente tendencia de las infecciones de transmisión sexual (ITS) de los últimos años se vio alterada tras la irrupción de la pandemia por SARS-CoV-2. Objetivos Describir el impacto de la pandemia por el coronavirus de tipo 2 causante del síndrome respiratorio agudo severo (SARS-CoV-2) en las declaraciones de ITS recibidas durante el período prepandémico al pandémico y estimar el número de casos de ITS esperados para el período pandémico. Material y métodos Análisis descriptivo de las declaraciones de ITS recibidas durante el período prepandémico (2018-2019) y pandémico (2020-2021). Se estudió mediante un modelo de correlación la influencia del número de casos positivos de SARS-CoV-2 con el número de casos positivos de ITS durante los meses de pandemia. Mediante el modelo de series temporales Holt-Wilson se realizó una estimación del número de casos de ITS esperados para el período pandémico. Resultado La tasa de incidencia global para todas las ITS en 2020 descendió un 18,3% respecto a 2019. La Clamidia y la sífilis presentaron una reducción superior en su incidencia de 2019 a 2020 del 22,7% y 20,9%, respectivamente y del 9,5% y del 2,5% para gonococia y linfogranuloma venéreo. Las estimaciones mostraron que en 2020 se hubieran producido un 44,6% más de ITS que las declaradas. Las proporciones según el sexo, el país de nacimiento y la orientación sexual cambiaron significativamente en clamidia y gonococia. Conclusiones Las medidas adoptadas para la prevención de contagios por SARS-CoV-2 pudieron conseguir un descenso inicial de los casos de ITS en 2020; sin embargo, este cambio no se mantuvo durante 2021, que acabó con las incidencias más elevadas recogidas hasta la fecha (AU)

Background The growing trend of STIs in recent years was altered after the outbreak of the SARS-CoV-2 pandemic. Objectives Describe the impact of the SARS-CoV-2 pandemic on STI declarations received during the pre-pandemic to pandemic period and estimate the number of STI cases expected for the pandemic period. Material and methods Descriptive analysis of STI declarations received during the pre-pandemic (2018-2019) and pandemic (2020-2021) periods. The influence of the number of positive cases of SARS-CoV-2 with the number of positive cases of STIs during the months of the pandemic was studied using a correlation model. Using the Holt-Wilson time series model, an estimate was made of the number of STI cases expected for the pandemic period. Results The global incidence rate for all STIs in 2020 decreased by 18.3% compared to 2019. Chlamydia and syphilis presented a greater reduction in their incidence from 2019 to 2020 of 22.7% and 20.9%, respectively and 9.5% and 2.5% for gonorrhea and LGV. Estimates showed that in 2020 there would have been 44.6% more STIs than those declared. The proportions according to sex, country of birth and sexual orientation changed significantly in chlamydia and gonorrhea. Conclusions The measures adopted for the prevention of SARS-CoV-2 infections were able to achieve an initial decrease in STI cases in 2020, however, this change was not maintained during 2021, which ended with higher incidences recorded to date (AU)

Facilitadores de la participación e implementación de la subcohorte PELFI de familias inmigrantes / Facilitators of participation and implementation of the immigrant families' PELFI Sub-Cohort

Objetivo: PELFI es un estudio multicéntrico de cohortes de familias inmigradas en España. Los objetivos de este manuscrito son: 1) describir el reclutamiento, la recogida de información y las características sociodemográficas según origen y sexo de los participantes de las familias; y 2) valorar las estrategias de reclutamiento y recogida de información que facilitaron la participación en la subcohorte PELFI Badalona/SC. Método: Estudio descriptivo con una muestra de conveniencia de familias inmigrantes y autóctonas residentes en Badalona y Santa Coloma de Gramanet. Se encuestaron los padres, madres e hijos >16 años, y se realizaron exámenes médicos. Resultados: Participaron 115 familias. Entre las estrategias de reclutamiento, la bola de nieve logró el 69% de cooperación. La tasa de cooperación del estudio fue del 57,5% y de los exámenes médicos del 66,6%. La cooperación de las familias chinas fue del 38,5% y no se reclutaron hijos >16 años. El 28% de las encuestas se realizaron en fin de semana o por la noche. Las familias tenían un tiempo medio de residencia de 12,2 años. El 71,2% de los hijos >16 años tenían estudios secundarios finalizados. Los inmigrantes tenían una clase social más baja que los autóctonos (p<0,05) y las mujeres inmigradas menor nivel de estudios (p<0,05). Conclusiones: Interaccionar frecuentemente con la comunidad, utilizar simultáneamente distintas estrategias de reclutamiento, incorporar investigadores del mismo origen geográfico que los participantes, minimizar las barreras idiomáticas y ofrecer flexibilidad de tiempo y lugar facilitó la participación. Las familias chinas presentaron mayores dificultades. Las conclusiones facilitarán la implementación de futuras cohortes de características similares

Objective: PELFI is a multicentre cohort study of migrant families in Spain. The objectives of this manuscript were: 1) to describe the recruitment strategies, data collection and the main socio-demographic characteristics according to geographical origin and sex of participants of the families; and 2) to assess the recruitment and data collection strategies that facilitated participation in the basal assessment of the Badalona and Santa Coloma de Gramanet cohort. Method: Descriptive study on a convenience sample of migrant and native families residing in Badalona and Santa Coloma de Gramanet. Health interviews were conducted on fathers, mothers and children>16 years; and medical examinations were performed. Results: There were 115 participating families. Within the recruitment strategies, snow ball achieved 69% cooperation. The cooperation rate of the study was 57.5% and that of the clinical sub-sample was 66.6%. Cooperation rate of the Chinese families was 38.5% and Chinese children >16 years old were not recruited. Twenty-eight percent of the interviews were conducted at weekends or during the evening. Families had a mean of 12.2 years of residence. Seventy-one point two percent of the children >16 years had completed secondary studies. The migrants had lower social class than natives (p < 0.05) and the migrant women had lower levels of education (p < 0.05). Conclusions: Interacting frequently with the community, using different recruitment strategies simultaneously, incorporating researchers from the same geographical origin as participants, minimising language barriers and offering flexibility in conducting data collection facilitated the participation of the migrant families. The Chinese families presented greater difficulties. The study findings will facilitate the implementation of future cohort studies with similar characteristics

Trends in human immunodeficiency virus diagnoses among men who have sex with men in North America, Western Europe, and Australia, 2000-2014.

PURPOSE: The aim of the article was to investigate recent trends in human immunodeficiency virus (HIV) diagnosis rates among men who have sex with men (MSM) in high-income countries in North America, Western Europe, and Australia. METHODS: Data on annual rates of HIV diagnoses among MSM aged 15 to 65 years from 2000 to 2014 were collected from 13 high-income countries. Joinpoint regression software was used to empirically determine country-specific trend periods. Trends in HIV diagnosis rates and in the proportion of diagnoses occurring in young MSM aged 15 to 24 years were analyzed using Poisson regression and log-binomial regression, respectively. RESULTS: Six countries experienced an increasing trend from 2000 to 2007-08 followed by either a stable or declining trend through 2014. Five countries had recently increasing trends, and two countries had one stable trend from 2000 to 2014. All 13 countries experienced increases in the proportion of diagnoses occurring in young MSM. CONCLUSIONS: Since 2008, half of the 13 high-income countries examined experienced stable or decreasing trends. Still, some countries continue to experience increasing HIV trends, and young MSM are increasingly represented among new diagnoses. Efforts to support early sexual health promotion, reduce barriers to pre-exposure prophylaxis, and improve care engagement for young MSM are critical to addressing current HIV trends.

Infección VIH/SIDA y otras infecciones de transmisión sexual en la población inmigrante en España. Revisión bibliográfica / HIV and other sexually transmitted infections among migrant population in Spain. A scoping review

Fundamentos: Los flujos migratorios tienen la capacidad de dispersar agentes infecciosos y alterar las epidemiologías locales. El objetivo del estudio es describir las características socio-epidemiológicas, clínicas y de microbiología/epidemiología molecular de la infección VIH/Sida en la población inmigrada.. Métodos: Revisión de la literatura científica mediante la metodología de Scoping Review. Se realizó una búsqueda bibliográfica en las bases de datosMedline yMEDES. Se seleccionaron artículos originales realizados en España y publicados entre 1998-2012, en los que participara población procedente deAmérica Latina, África subsahariana, Norte de África,Asia y Europa del Este. Resultados: Se seleccionaron 41 artículos. La población más estudiada fue la de América Latina (48,8%). Se observaron prevalencias mayores de VIH que en autóctonos en los hombres que tienen sexo con hombresde América Latina (18,1%), travestis y transexuales trabajadores del sexo de América Latina (23,3%), mujeres gestantes (0,9%) y hombres y mujeres de África Subsahariana (9,1% y 7,5%). Las conductas de riesgo fueron diferentes en función del país de origen y del sexo. El retraso diagnóstico llegó al 43% de las infecciones VIH, hallándose mayor prevalencia en inmigrantes de África subsahariana, que mostraron retraso diagnóstico en el 41% y resistencias al tratamiento anti-retroviral en el 13%. Las mujeres inmigrantes presentaron más pérdidas de seguimiento, peor respuesta inmunológica al TARV y menor tiempo de fracaso terapéutico. Conclusiones: La mayor prevalencia de VIH la presentan los sujetos procedentes de África subsahariana y los hombres que tienen sexo con hombres y travestis y transexuales trabajadores del sexo de América Latina. También las mujeres gestantes. El retraso diagnóstico y las resistencias al tratamiento son más frecuentes en sujetos de África Subsahariana. Las mujeres inmigrantes respondieron peor al tratamiento antiretroviral (AU)

Background: Migration flows have the ability to disperse infectious agents and alter local epidemiologies. The aim of the study is to describe the socio-epidemiological, clinical and microbiology / molecular epidemiology of HIV /AIDS infection in the immigrant population. Methods: Review of the literature following the methodology Scoping review. A literature search in Medline and MEDES, original items made in Spain, published between 1998-2012, with people from Latin America, sub-Saharan Africa, North Africa, Asia and / or Eastern Europe was conducted. Results: 41 articles were selected. The most studied population was from Latin America (48.8%). Higher HIV prevalence than in native was observed in men who have sex with men from Latin America (18.1%), transvestite and transsexual sex workers from Latin America (23.3%), pregnant women (0.9% ) and men and women from sub-Saharan Africa (9.1% and 7.5%). Risk behaviors were different depending on the country of origin and sex. The diagnostic delay of HIV infections reached 43%, with higher prevalence in immigrants from sub-Saharan Africa, which showed delayed diagnosis in 41% and resistance to anti-retroviral treatment in 13%. Immigrant women had more losses to follow up, worse immunological response to antiretroviral treatment and shorter time treatment failure. Conclusion: Higher prevalence of HIV is presented by subjects from sub-Saharan Africa, men who have sex with men and transgender and transvestite sex workers fromLatinAmerica.Also pregnant women. Delayed diagnosis and resistance to treatment are more common in individuals from sub-SaharanAfrica. Immigrant women presented poorer response to antiretroviral treatment (AU)
