RESUMEN Introducción: La bacteria Chlamydia trachomatis provoca una de las infecciones de transmisión sexual más frecuente. La Organización Mundial de la Salud reporta aproximadamente 131 millones de casos anuales. Objetivo: Evaluar el desempeño de la prueba rápida CROMATEST (Linear Chemicals. S.L. Barcelona España) en muestras clínicas. Métodos: Se estudiaron 72 muestras: 38 exudados vaginales de adolescentes de los hospitales pediátricos Juan Manuel Márquez y el Cerro; y 34 muestras de orina de voluntarios del Instituto de Medicina Tropical “Pedro Kourí. Se empleó el ensayo CROMATEST y como prueba de referencia la reacción en cadena de la polimerasa en tiempo real comercial. Se calculó sensibilidad, especificidad, valor predictivo positivo y negativo. Resultados: Seis muestras resultaron positivas por el test rápido, cinco por la reacción en cadena de la polimerasa en tiempo real y una por la prueba de referencia. De las 66 muestras negativas, una fue negativa para la reacción en cadena de la polimerasa en tiempo real y positiva en el CROMATEST. El porcentaje de concordancia entre ambas pruebas fue del 95 % y el valor de Kappa 0,8182. Se obtuvo una sensibilidad de 83,33 %, una especificidad del 98,48 % y valores predictivos positivo y negativo de 83,33 % y 98,48 %, respectivamente. Conclusiones: La prueba rápida CROMATEST tuvo un desempeño excelente contra la prueba de referencia; por tanto, se recomienda su utilización para la detección de Chlamydia trachomatis.

ABSTRACT Introduction: The bacterium Chlamydia trachomatis causes one of the most common sexually transmitted infections. The World Health Organization reports approximately 131 million cases annually. Objective: To evaluate the performance of the CROMATEST rapid test (Linear Chemicals. S.L. Barcelona Spain) in clinical specimens. Methods: 72 samples were studied: 38 vaginal exudates from adolescents from the Juan Manuel Márquez and El Cerro pediatric hospitals; and 34 urine samples from volunteers from the "Pedro Kourí" Tropical Medicine Institute. The CROMATEST assay was used and the commercial real-time polymerase chain reaction was used as a reference test. Sensitivity, specificity, positive and negative predictive value were calculated. Results: Six samples were positive by the rapid test, five by the real-time polymerase chain reaction and one by the reference test. The negative samples were 66, of which one was negative for the real-time polymerase chain reaction and positive in the CROMATEST. The concordance between both tests was 95 % and the Kappa value 0.8182. A sensitivity of 83.33 %, a specificity of 98.48 % and positive and negative predictive values of 83.33 % and 98.48 %, respectively, were obtained. Conclusions: The CROMATEST rapid test performed excellently against the reference test; therefore, its use is recommended for the detection of Chlamydia trachomatis.

ABSTRACT Background: Trachoma is the leading infectious cause of blindness worldwide. It is a neglected tropical disease caused by Chlamydia trachomatis. The objective of this study was to analyze the trachoma-associated morbidity and mortality in Brazil from 2000 to 2022. This ecological time-series study was based on secondary data on trachoma obtained from hospital admissions (trachoma as the primary or secondary cause) and death certificates (trachoma as the underlying or associated cause). Methods: We calculated the sex- and age-standardized rates of hospital admissions and trachoma-specific mortality according to sociodemographic variables and analyzed the spatial distribution. Results: We identified 141/263,292,807 hospital admissions (primary cause: 83.0%) and 126/27,596,830 death certificates (associated cause: 91.3%) related to trachoma. Trachoma-related sequelae were reported in 8.5% of hospital admissions and 6.3% of death certificates. Trachoma was more common in males (hospital admissions and death certificates), people aged ≥70 years (hospital admissions and death certificates), those with brown skin (hospital admissions and death certificates), and those living in the North (hospital admissions) and Northeast (death certificates) regions of Brazil. Conclusions: Despite the relatively low rates of trachoma morbidity in Brazil, the associated mortality rates are of concern. The heterogeneous patterns of occurrence in the country in terms of population and territory reinforce the need to evaluate and monitor the available data, despite the low prevalence, in order to achieve and maintain the elimination targets in Brazil in the future.

Resumen: El objetivo de este estudio fue conocer la opinión de los profesionales participantes de la implantación piloto de pruebas moleculares para la detección de Chlamydia trachomatis y Neisseria gonorrhoeae en el Sistema Único de Salud brasileño (SUS). Se determinó la tasa de detección de C. trachomatis y/o N. gonorrhoeae y los factores asociados con la infección. En la estrategia participaron laboratorios pertenecientes a la red de carga viral de VIH y hepatitis virales. La prueba tuvo como público objetivo a personas más vulnerables a las infecciones de transmisión sexual, con recolección de muestras de orina y/o swabs vaginal, endocervicales y/o uretral masculino. Se enviaron cuestionarios a los gestores estatales y a los profesionales de laboratorio sobre la implementación piloto. En general, las evaluaciones fueron positivas. Entre las debilidades, se citó las dificultades en el cambio del proceso de trabajo, la falta de recursos humanos, los profesionales de la asistencia poco sensibilizados y la ausencia del contenedor de orina primaria, el único insumo no suministrado. Como fortalezas, se destaca la adquisición centralizada de pruebas, el intercambio de equipos y el almacenamiento de muestras a temperatura ambiente. De las 16.177 personas evaluadas, 1.004 (6,21%) fueron positivas para C. trachomatis, 1.036 (6,4%) para N. gonorrhoeae y 239 (1,48%) para C. trachomatis/N. gonorrhoeae. La detección de alguna infección ocurrió más en personas jóvenes (≤ 24 vs. > 24 años) (aOR = 2,65; IC95%: 2,38-2,96), del sexo masculino (aOR = 1,95; IC95%: 1,72-2,21), parda/negra (aOR = 1,06; IC95%: 1,05-1,11), localizadas en la región Sudeste (aOR = 1,08; IC95%: 1,02-1,13) y en muestras de secreción uretral (aOR = 1,46; IC95%: 1,41-1,52). Los resultados de este estudio demostraron la importancia de la disponibilidad de la prueba a nivel nacional, los cuales subsidiaron la implantación de la red definitiva para detección de C. trachomatis/N. gonorrhoeae en el SUS.

Resumo: O objetivo deste estudo foi conhecer a opinião dos profissionais participantes da implantação-piloto de testes moleculares para detecção de Chlamydia trachomatis e Neisseria gonorrhoeae no Sistema Único de Saúde (SUS). Determinou-se a taxa de detecção de C. trachomatis e/ou N. gonorrhoeae e os fatores associados à infecção. A estratégia contou com laboratórios pertencentes à rede de carga viral de HIV e hepatites virais. A testagem teve como público-alvo pessoas mais vulnerabilizadas às infecções sexualmente transmissíveis, com coleta de amostras de urina e/ou swabs vaginal, endocervical e/ou uretral masculino. Questionários foram enviados aos gestores estaduais e profissionais de laboratório sobre a implantação-piloto. De maneira geral, as avaliações foram positivas. Entre as fraquezas, citou-se dificuldades na mudança do processo de trabalho, carência de recursos humanos, pouca sensibilidade de profissionais da assistência e ausência de tubo primário de urina, único insumo não fornecido. Como fortaleza, destaca-se aquisição centralizada de testes, compartilhamento de equipamentos e armazenamento de amostras à temperatura ambiente. Das 16.177 pessoas testadas, 1.004 (6,21%) foram positivas para C. trachomatis, 1.036 (6,4%) para N. gonorrhoeae e 239 (1,48%) para C. trachomatis/N. gonorrhoeae. A detecção de infecção ocorreu mais em pessoas jovens (≤ 24 vs. > 24 anos) (aOR = 2,65; IC95%: 2,38-2,96), do sexo masculino (aOR = 1,95; IC95%: 1,72-2,21), pardas/pretas (aOR = 1,06; IC95%: 1,05-1,11), na Região Sudeste (aOR = 1,08; IC95%: 1,02-1,13) e em amostras de secreção uretral (aOR = 1,46; IC95%: 1,41-1,52). Os resultados deste estudo demonstraram a importância da disponibilização da testagem em âmbito nacional, os quais subsidiaram a implantação da rede definitiva para detecção de C. trachomatis/N. gonorrhoeae no SUS.

Abstract: This study aimed to know the opinion of professionals participating in an experiment to implement a pilot for molecular tests to detect Chlamydia trachomatis and Neisseria gonorrhoeae at the Brazilian Unified National Health System (SUS). The detection rate of C. trachomatis and/or N. gonorrhoeae and the factors associated with infection were determined. The strategy included laboratories belonging to the HIV and viral hepatitis viral load network. Testing targeted people who are more vulnerable to sexually transmitted infections and collected urine samples and/or vaginal, endocervical, and/or male urethral swabs. Questionnaires were sent to state managers and laboratory professionals about the implementation of the pilot. Reviews were overall positive. Weaknesses included difficulties changing work processes, lack of human resources, poorly sensitized care professionals, and absence of primary urine tubes, the only input not provided. Strengths included the centralized acquisition of tests, sharing of equipment, and storage of samples at room temperature. Of the 16,177 people who were tested, 1,004 (6.21%) were positive for C. trachomatis; 1,036 (6.4%), for N. gonorrhoeae; and 239 (1.48%), for C. trachomatis/N. gonorrhoeae . Detection of any infection occurred more frequently in young people (≤ 24 vs. > 24 years) (adjOR = 2.65; 95%CI: 2.38-2.96), men (adjOR = 1.95; 95%CI: 1.72-2.21), brown/black individuals (adjOR = 1.06; 95%CI: 1.05-1.11), those in Southeastern Brazil (adjOR = 1.08; 95%CI: 1.02-1.13), and in urethral secretion samples (adjOR = 1.46; 95%CI: 1.41-1.52). Results show the importance of making testing available nationwide, which supported the implementation of a definitive network to detection C. trachomatis/N. gonorrhoeae in SUS.

RESUMO Objetivo: Estimar as prevalências e os fatores associados à detecção de Chlamydia trachomatis (CT) e Neisseria gonorrhoeae (NG) em mulheres trans e travestis em cinco capitais brasileiras. Métodos: Os dados vieram de um estudo transversal, realizado entre 2019 e 2021, com pessoas recrutadas por RDS (respondent driven sampling) em São Paulo, Campo Grande, Manaus, Porto Alegre e Salvador. Analisou-se a detecção de CT e NG, em três sítios de coleta (anorretal, orofaríngeo e uretral). Para identificação dos fatores associados empregaram-se modelos logísticos com efeitos mistos. Resultados: Forneceram material biológico para detecção dessas infecções 1.297 participantes recrutadas. As prevalências de CT, NG e coinfecção foram, respectivamente, 11,5, 13,3 e 3,6%. Foram independentemente associados à detecção para CT: trabalho sexual no passado (odds ratio — OR=1,73; intervalos de confiança para 95% — IC95% 1,02–2,95), no momento atual (OR=2,13; IC95% 1,23–3,69) e como atividade parcial (OR=2,75; IC95% 1,60–4,75) e uso de drogas injetáveis na vida (OR=3,54; IC95% 1,49–8,40). Para NG: uso de drogas injetáveis na vida (OR=1,91; IC95% 1,28–2,84) e orientação sexual – heterossexuais (OR=3,44; IC95% 1,35–8,82), homossexuais (OR=5,49; IC95% 1,89–15,97) e bissexuais (OR=3,21; IC95% 1,06–9,68). Para coinfecção: uso de drogas nos últimos 12 meses (OR=2,34; IC95% 1,10–5,00). Ser mais jovem foi associada a todos os desfechos investigados. Conclusão: As prevalências estimadas de CT, NG e de coinfecção foram desproporcionalmente mais elevadas entre as mulheres trans e travestis se comparadas à população geral, especialmente entre as mais jovens, que exerciam trabalho sexual e faziam uso de drogas.

ABSTRACT Objective: To estimate the prevalence and factors associated with the detection of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) in transgender women and travestis in five Brazilian capitals. Methods: Data were obtained from a cross-sectional study conducted between 2019 and 2021, with participants recruited through Respondent Driven Sampling in São Paulo, Campo Grande, Manaus, Porto Alegre and Salvador. Detection of CT and NG was analyzed at three collection sites (anorectal, oropharyngeal and urethral). Mixed logistic regression models were employed to identify associated factors. Results: A total of 1,297 recruited participants provided biological material to detect these infections. The prevalences of CT, NG and coinfection were 11.5%, 13.3% and 3.6%, respectively. Independent associations with CT infections included past (OR=1.73; 95%CI 1.02–2.95), current (OR=2.13; 95%CI 1.23–3.69), and part-time sex work (OR=2.75; 95%CI 1.60–4.75), as well as lifetime injectable drug use (OR=3.54; 95%CI 1.49–8.40). For NG, associations were observed with lifetime injectable drug use (OR=1.91; 95%CI 1.28–2.84) and sexual orientation, including heterosexual (OR=3.44; 95%CI 1.35–8.82), homosexual (OR=5.49; 95%CI 1.89–15.97), and bisexual (OR=3.21; 95%CI 1.06–9.68). Coinfection was associated with use of illicit drugs in the last 12 months (OR=2.34, 95%CI 1.10–5.00), and younger age was associated with all investigated outcomes. Conclusion: Estimated prevalences of CT, NG and co-infection were higher among transgender women and travestis compared to the general population, particularly among younger, individuals engaged in sex work and illicit drug use.

RESUMO Objetivo As infecções sexualmente transmissíveis (IST) afetam desproporcionalmente as mulheres trans e travestis (MTT), que muitas vezes não têm acesso a cuidados de saúde devido ao estigma e à discriminação. Descrevemos a abordagem e a metodologia de um estudo que investigou a prevalência de sífilis, HIV, hepatite A, B e C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT) e papilomavírus humano (HPV) entre as MTT, bem como seu conhecimento e percepção sobre a sífilis, para melhor as políticas para redução de IST nessa população vulnerável. Métodos: TransOdara foi um estudo multicêntrico, transversal, realizado em cinco capitais das principais regiões brasileiras entre dezembro de 2019 e julho de 2021. Mulheres autoidentificadas como mulheres trans ou travestis, com idade >18 anos, foram recrutadas usando respondent-driven sampling, após uma fase de pesquisa formativa. Responderam a um questionário conduzido por entrevistadoras. Foi oferecida consulta médica, com exame físico, e solicitou-se que fornecessem amostras de vários locais para detectar as IST citadas. Quando indicado e consentido, foram iniciadas a vacinação e o tratamento. Resultados: Foram recrutadas 1.317 participantes nos cinco locais de estudo: Campo Grande (n=181, 13,7%), Manaus (n=340, 25,8%), Porto Alegre (n=192, 14,6%), Salvador (n= =201, 15,3%) e São Paulo (n=403, 30,6%). O período de recrutamento variou em cada local em razão de restrições logísticas impostas pela pandemia de COVID-19. Conclusão: Apesar dos enormes desafios colocados pela ocorrência simultânea da pandemia da COVID-19 e do trabalho de campo dirigido a uma população vulnerabilizada e dispersa, o projeto TransOdara foi eficazmente implementado. As adversidades não impediram que mais de 1.300 mulheres trans e travestis tenham sido entrevistadas e testadas em meio a uma epidemia de tal magnitude que perturbou os serviços de saúde e os projetos de pesquisa no Brasil e no mundo.

ABSTRACT Objective Sexually transmitted infections (STIs) disproportionately affect transgender women and travestis (TGW), who often lack access to healthcare due to stigma and discrimination. We describe the approach and methodology of a study investigating the prevalence of syphilis, HIV, hepatitis A, B, and C, Neisseria gonorrhoeae (NG), Chlamydia trachomatis (CT), and human papillomavirus (HPV) among TGW, as well as their knowledge and perceptions regarding syphilis, to better inform policies to curb STIs among this vulnerable population. Methods: TransOdara was a multicentric, cross-sectional study conducted among TGW in five capital cities from major Brazilian regions between December 2019 and July 2021. Self-identified transgender women and travestis aged >18 years were recruited using respondent-driven sampling after a qualitative formative phase, completed an interviewer-led questionnaire, were offered a physical examination, and were also asked to provide samples from multiple sites to detect various STIs, starting vaccination and treatment when indicated. Results: A total of 1,317 participants were recruited from the five study locations: Campo Grande (n=181, 13.7%), Manaus (n=340, 25.8%), Porto Alegre (n=192, 14.6%), Salvador (n=201, 15.3%), and São Paulo (n=403, 30.6%). The recruitment period varied at each study location due to logistic constraints imposed by the COVID-19 pandemic. Conclusion: Despite the enormous challenges posed by the co-occurrence of the COVID-19 pandemic and field work targeting a vulnerable, elusive, and scattered population, the TransOdara project has been effectively implemented. Caveats did not preclude 1,300 TGW from being interviewed and tested, amid a significant epidemic that disrupted health services and research projects in Brazil and worldwide.

RESUMO Objetivo: Estimar as prevalências e os fatores associados à detecção de Chlamydia trachomatis (CT) e Neisseria gonorrhoeae (NG) em mulheres trans e travestis em cinco capitais brasileiras. Métodos: Os dados vieram de um estudo transversal, realizado entre 2019 e 2021, com pessoas recrutadas por RDS (respondent driven sampling) em São Paulo, Campo Grande, Manaus, Porto Alegre e Salvador. Analisou-se a detecção de CT e NG, em três sítios de coleta (anorretal, orofaríngeo e uretral). Para identificação dos fatores associados empregaram-se modelos logísticos com efeitos mistos. Resultados: Forneceram material biológico para detecção dessas infecções 1.297 participantes recrutadas. As prevalências de CT, NG e coinfecção foram, respectivamente, 11,5, 13,3 e 3,6%. Foram independentemente associados à detecção para CT: trabalho sexual no passado (odds ratio — OR=1,73; intervalos de confiança para 95% — IC95% 1,02–2,95), no momento atual (OR=2,13; IC95% 1,23–3,69) e como atividade parcial (OR=2,75; IC95% 1,60–4,75) e uso de drogas injetáveis na vida (OR=3,54; IC95% 1,49–8,40). Para NG: uso de drogas injetáveis na vida (OR=1,91; IC95% 1,28–2,84) e orientação sexual – heterossexuais (OR=3,44; IC95% 1,35–8,82), homossexuais (OR=5,49; IC95% 1,89–15,97) e bissexuais (OR=3,21; IC95% 1,06–9,68). Para coinfecção: uso de drogas nos últimos 12 meses (OR=2,34; IC95% 1,10–5,00). Ser mais jovem foi associada a todos os desfechos investigados. Conclusão: As prevalências estimadas de CT, NG e de coinfecção foram desproporcionalmente mais elevadas entre as mulheres trans e travestis se comparadas à população geral, especialmente entre as mais jovens, que exerciam trabalho sexual e faziam uso de drogas.

Abstract: This study aimed to know the opinion of professionals participating in an experiment to implement a pilot for molecular tests to detect Chlamydia trachomatis and Neisseria gonorrhoeae at the Brazilian Unified National Health System (SUS). The detection rate of C. trachomatis and/or N. gonorrhoeae and the factors associated with infection were determined. The strategy included laboratories belonging to the HIV and viral hepatitis viral load network. Testing targeted people who are more vulnerable to sexually transmitted infections and collected urine samples and/or vaginal, endocervical, and/or male urethral swabs. Questionnaires were sent to state managers and laboratory professionals about the implementation of the pilot. Reviews were overall positive. Weaknesses included difficulties changing work processes, lack of human resources, poorly sensitized care professionals, and absence of primary urine tubes, the only input not provided. Strengths included the centralized acquisition of tests, sharing of equipment, and storage of samples at room temperature. Of the 16,177 people who were tested, 1,004 (6.21%) were positive for C. trachomatis; 1,036 (6.4%), for N. gonorrhoeae; and 239 (1.48%), for C. trachomatis/N. gonorrhoeae . Detection of any infection occurred more frequently in young people (≤ 24 vs. > 24 years) (adjOR = 2.65; 95%CI: 2.38-2.96), men (adjOR = 1.95; 95%CI: 1.72-2.21), brown/black individuals (adjOR = 1.06; 95%CI: 1.05-1.11), those in Southeastern Brazil (adjOR = 1.08; 95%CI: 1.02-1.13), and in urethral secretion samples (adjOR = 1.46; 95%CI: 1.41-1.52). Results show the importance of making testing available nationwide, which supported the implementation of a definitive network to detection C. trachomatis/N. gonorrhoeae in SUS.

Resumen: El objetivo de este estudio fue conocer la opinión de los profesionales participantes de la implantación piloto de pruebas moleculares para la detección de Chlamydia trachomatis y Neisseria gonorrhoeae en el Sistema Único de Salud brasileño (SUS). Se determinó la tasa de detección de C. trachomatis y/o N. gonorrhoeae y los factores asociados con la infección. En la estrategia participaron laboratorios pertenecientes a la red de carga viral de VIH y hepatitis virales. La prueba tuvo como público objetivo a personas más vulnerables a las infecciones de transmisión sexual, con recolección de muestras de orina y/o swabs vaginal, endocervicales y/o uretral masculino. Se enviaron cuestionarios a los gestores estatales y a los profesionales de laboratorio sobre la implementación piloto. En general, las evaluaciones fueron positivas. Entre las debilidades, se citó las dificultades en el cambio del proceso de trabajo, la falta de recursos humanos, los profesionales de la asistencia poco sensibilizados y la ausencia del contenedor de orina primaria, el único insumo no suministrado. Como fortalezas, se destaca la adquisición centralizada de pruebas, el intercambio de equipos y el almacenamiento de muestras a temperatura ambiente. De las 16.177 personas evaluadas, 1.004 (6,21%) fueron positivas para C. trachomatis, 1.036 (6,4%) para N. gonorrhoeae y 239 (1,48%) para C. trachomatis/N. gonorrhoeae. La detección de alguna infección ocurrió más en personas jóvenes (≤ 24 vs. > 24 años) (aOR = 2,65; IC95%: 2,38-2,96), del sexo masculino (aOR = 1,95; IC95%: 1,72-2,21), parda/negra (aOR = 1,06; IC95%: 1,05-1,11), localizadas en la región Sudeste (aOR = 1,08; IC95%: 1,02-1,13) y en muestras de secreción uretral (aOR = 1,46; IC95%: 1,41-1,52). Los resultados de este estudio demostraron la importancia de la disponibilidad de la prueba a nivel nacional, los cuales subsidiaron la implantación de la red definitiva para detección de C. trachomatis/N. gonorrhoeae en el SUS.

Resumo: O objetivo deste estudo foi conhecer a opinião dos profissionais participantes da implantação-piloto de testes moleculares para detecção de Chlamydia trachomatis e Neisseria gonorrhoeae no Sistema Único de Saúde (SUS). Determinou-se a taxa de detecção de C. trachomatis e/ou N. gonorrhoeae e os fatores associados à infecção. A estratégia contou com laboratórios pertencentes à rede de carga viral de HIV e hepatites virais. A testagem teve como público-alvo pessoas mais vulnerabilizadas às infecções sexualmente transmissíveis, com coleta de amostras de urina e/ou swabs vaginal, endocervical e/ou uretral masculino. Questionários foram enviados aos gestores estaduais e profissionais de laboratório sobre a implantação-piloto. De maneira geral, as avaliações foram positivas. Entre as fraquezas, citou-se dificuldades na mudança do processo de trabalho, carência de recursos humanos, pouca sensibilidade de profissionais da assistência e ausência de tubo primário de urina, único insumo não fornecido. Como fortaleza, destaca-se aquisição centralizada de testes, compartilhamento de equipamentos e armazenamento de amostras à temperatura ambiente. Das 16.177 pessoas testadas, 1.004 (6,21%) foram positivas para C. trachomatis, 1.036 (6,4%) para N. gonorrhoeae e 239 (1,48%) para C. trachomatis/N. gonorrhoeae. A detecção de infecção ocorreu mais em pessoas jovens (≤ 24 vs. > 24 anos) (aOR = 2,65; IC95%: 2,38-2,96), do sexo masculino (aOR = 1,95; IC95%: 1,72-2,21), pardas/pretas (aOR = 1,06; IC95%: 1,05-1,11), na Região Sudeste (aOR = 1,08; IC95%: 1,02-1,13) e em amostras de secreção uretral (aOR = 1,46; IC95%: 1,41-1,52). Os resultados deste estudo demonstraram a importância da disponibilização da testagem em âmbito nacional, os quais subsidiaram a implantação da rede definitiva para detecção de C. trachomatis/N. gonorrhoeae no SUS.

ABSTRACT Introduction: Chlamydia trachomatis (CT) infection is recognized as the most common bacterial sexually transmitted infection (STI). The World Health Organization reports approximately 131 million cases annually. Objective: To evaluate the performance of the CROMATEST rapid test (Linear Chemicals. S.L. Barcelona España), using clinical samples. Methods: A total of 72 individuals were studied (27 women and 7 men), and the same number of clinical samples. Of which, 38 vaginal swabs from adolescents with symptoms of STI from two pediatric hospitals from Havana, and 34 urine samples from apparently healthy volunteers, from the “Pedro Kourí” Institute of Tropical Medicine (IPK). The CROMATEST assay was applied to the samples and a commercial RT-PCR was used as reference test. Sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated. Results: Of the samples under study, six were positive by the CROMATEST rapid test, while five were reactive for CT by mean of RT-PCR. One sample was only reactive by the reference test. Of the 66 negative samples, 65 were non-reactive by both tests; one sample was negative by RT-PCR and positive by CROMATEST. The percentage of agreement between both tests was 95 % and the Kappa value 0.8182. A sensitivity 83.33 %, specificity 98.48 %, PPV 83.33 % and NPV 98.48 %, were obtained. Conclusion: The CROMATEST rapid test had an excellent performance when evaluated against the reference test; we recommend its use as a rapid test for the detection of CT.

RESUMEN Introducción: La infección por Chlamydia trachomatis (CT) se reconoce como la infección de transmisión sexual (ITS) bacteriana más frecuente. La Organización Mundial de la Salud, reporta aproximadamente 131 millones de casos anuales. Objetivo: Evaluar el desempeño de la prueba rápida CROMATEST (Linear Chemicals. S.L. Barcelona, España) en muestras clínicas. Métodos: Se estudiaron 72 individuos (27 mujeres y 7 hombres) y el mismo número de muestras. De ellas, 38 exudados vaginales de adolescentes con sospecha de ITS atendidas en dos hospitales pediátricos de La Habana, y 34 muestras de orina de voluntarios, aparentemente sanos, del Instituto de Medicina Tropical “Pedro Kourí”. Se aplicó el ensayo CROMATEST para la detección de CT y como prueba de referencia, una PCR-Tiempo Real (PCR-TR) comercial. Se calcularon, sensibilidad, especificidad, valor predictivo positivo (VPP) y negativo (VPN). Resultados: De las muestras estudiadas, seis resultaron positivas por la prueba rápida y cinco por la PCR-TR, una fue positiva sólo por la prueba de referencia. De las 66 muestras negativas, 65 fueron no reactivas por ambas pruebas, una fue negativa por PCR-TR y positiva por CROMATEST. El porcentaje de concordancia entre ambas pruebas fue del 95 % y el valor de Kappa 0,8182. Se obtuvo una sensibilidad de 83,33 %, una especificidad del 98,48 %, VPP de 83,33 % y VPN de 98,48 %. Conclusión: La prueba rápida CROMATEST tuvo un desempeño excelente al compararla con la prueba de referencia, por esta razón recomendamos su utilización como prueba rápida para la detección de CT.

Resumen Introducción: La infección por Chlamydia trachomatis es la ITS bacteriana más frecuente del mundo. En el cervix se presenta mayormente de forma asintomática y afecta especialmente a mujeres jóvenes y adolescentes. Puede producir daño permanente en el tracto reproductor femenino, se asocia a parto prematuro, infecciones neonatales transmitidas vía vertical y mayor riesgo de adquirir otras ITS como VIH Y VPH. Por estos motivos se han establecido estrategias de tamizaje para detectar y tratar precozmente la infección asintomática por C. trachomatis en diferentes países. En nuestro país no contamos con un programa nacional de tamizaje. Objetivo: Determinar la prevalencia de infección asintomática por Chlamydia trachomatis en mujeres entre 12 y 21 años de la Provincia de Osorno, Región de Los Lagos, Chile. Pacientes y Métodos: Se desarrolló un estudio de diseño transversal con una cohorte única de mujeres adolescentes y jóvenes consultantes en el Policlínico de Alto Riesgo Obstétrico y de Ginecología Infantil y Adolescente, del Hospital Base de Osorno, entre enero de 2019 y enero 2020. Se determinó el estado de infección asintomática mediante RPC en tiempo real para C. trachomatis. Se realizó una encuesta a fin de determinar características demográficas, hábitos y conductas sexuales de las pacientes estudiadas. Resultados: Fueron reclutadas 124 mujeres entre 12 a 21 años de edad, de las cuales, 36 (29,3%) se encontraban embarazadas al momento del estudio. La prevalencia de infección asintomática por C. trachomatis fue de 14/124 (11,3%). En las mujeres gestantes se encontraron 6/36 (16,7%) casos positivos de infección por C. trachomatis y 8/88 (9,1%) en las no gestantes. Existe una mayor frecuencia de infección asintomática a menor edad de inicio de actividad sexual (33,3% en aquellas que inician entre 11-12 años vs. 16,2% en las que inician entre 1314 años, 7,4% entre 15-16 y 8% entre 17-21 años; p < 0,05). Esta tendencia no fue observada al comparar el estado de infección con el tiempo de vida sexual activa. Sólo 15,7% de las pacientes utilizó preservativo en todas sus relaciones sexuales. Discusión: La infección asintomática por C. trachomatis es frecuente en las mujeres adolescentes y jóvenes sexualmente activas. Las pacientes con inicio más temprano de la actividad sexual coital (bajo 13 años de edad) podrían estar en mayor riesgo. Se requiere con urgencia establecer la frecuencia nacional de infección para desarrollar una estrategia sanitaria para su pesquisa y manejo oportuno en nuestro país.

Abstract Background: Chlamydia trachomatis infection is the world most common bacterial STI. At uterine cervix it presents mostly asymptomatically and especially affects young women and adolescents. It can cause permanent damage to the female reproductive tract and is associated with premature birth, connatal infections and increased risk of acquiring other STIs such as HIV and HPV. For these reasons, other countries have established screening strategies to detect and treat asymptomatic C. trachomatis infection. Our country don’t have a national screening program. Aim: To determine the prevalence of C. trachomatis asymptomatic infection in adolescent and young women in Osorno province, Los Lagos Region, Chile. Methods: A crosssectional study was performed in adolescent and young women who consult at Hospital Base Osorno in the MaternoFetal and PediatricAdolescent Gynecology ambulatory clinics, between January 2019 and January 2020. The status of asymptomatic infection was determined by PCR for C. trachomatis. A survey was carried out to determine the demographic characteristics, habits and sexual behaviors. Results: 124 women between 12 and 21 years of age were recruited, of which 36 (29,3%) were pregnant at the time of the study. The prevalence of asymptomatic infection by C. trachomatis was 11.3.%. In pregnant women, there were 6/36 (16.7%) positive cases for C. trachomatis and 8/88 (9.1%) in nonpregnant women. We found a higher frequency of asymptomatic infection at younger age of first sexual intercourse (33% in adolescents at 11-12 years old vs. 16.2% at 13-14, 7.4% at 15-16 and 8% at 17-21; p<0.05). Only 15.7% of the patients utilized condoms in all their intercourses. Discussion: Asymptomatic C. trachomatis infection is common in adolescent and young women, with a higher risk in those who onset sexual activity at an early age (less than 13 years old). It is urgently required to determine the national frequency of asymptomatic C. trachomatis infection to develop a national strategy for screening and timely treatment.

Abstract Background The factors associated with bacterial vaginosis in women with homosexual, bisexual and heterosexual practices are still poorly explored. Thus, the aim of this study was to analyze the factors associated with bacterial vaginosis in women with different sexual practices. Methods Cross-sectional study that included 453 women, 149 Women with Homosexual practice (WSW); 80 bisexual Women (WSWM) and 224 Women with heterosexual practice (WSM). The diagnosis of bacterial vaginosis was performed by microscopic examination of the vaginal smears stained by Gram method and classified according to the Nugent et al. (1991) score. Data analysis was performed by Cox multiple regression. Results Bacterial vaginosis was associated to years of education among WSW (0.91 [95% CI 0.82‒0.99]; p= 0.048) and non-white skin color (2.34 [95% CI 1.05‒5.19]; p= 0.037) between WSWM. Changing partners in the last 3-months (2.09 [95% CI 1.14‒3.82]; p= 0.017), inconsistent use of condoms (2.61 [95% CI 1.10‒6.20]; p= 0.030) and positive diagnosis of Chlamydia trachomatis (2.40 [95% CI 1.01‒5.73]; p= 0.048) were associated with bacterial vaginoses only in WSH. Conclusions The factors associated to bacterial vaginosis differ between different sexual practices, suggesting that the type of sexual partner may influence the risk of developing this classic dysbiosis. homosexual explored Thus Crosssectional Cross sectional 45 14 (WSW) 8 WSWM (WSWM 22 WSM.

BACKGROUND: Sexually transmitted infections (STIs) are a global public health concern and sub-Saharan Africa, has limited data on STIs in the men who have sex with men (MSM) population. Syndromic management has controversies for treating asymptomatic STIs (ASTIs AIM: The aim of this study was to describe the risk factors for STIs among MSM SETTING: This study was conducted in Tshwane North, Gauteng Province in South Africa METHODS: A cross-sectional quantitative design was employed using structured questionnaires, rapid plasma reagent test, from December 2021 to May 2022. Bivariate and multivariate analyses were used for statistical analysis RESULTS: A total of 200 MSM with the mean age of 27.6, standard deviations: 6.8 participated, and STIs prevalence was 66%, with 37% concurrent infections. Ureaplasma urealyticum was (24%), Mycoplasma hominis (23%), Chlamydia trachomatis (20%), Treponema pallidum (20%) and Neisseria gonorrhoeae (9%). The risk factors for acquisition of STI include having a new partner in the last month (OR = 1.68; CI: 0.98-3.13 CONCLUSION: The prevalence of ASTIs is high. Serial and multiple sexual partners are the risk factors CONTRIBUTION: This study contributes to the body of knowledge of the burden of STIs among high-risk population

Abstract Introduction: Genital Chlamydia trachomatis infection is one of the most frequent in the world; about 85 million new cases of this pathology are registered each year, which causes severe complications in women and newborns. Objective: To determine the clinical-epidemiological characteristics of C. trachomatis infection in sexually active Venezuelan women. Materials and methods: Descriptive, cross-sectional, and field study based on the clinical history and physical examination, detection of infection with immunoenzymatic assay with anti-LPS polyclonal antibody and confirmation of results with molecular biology test. The sample consisted of 100 sexually active women over 12 years of age from Carabobo state, Venezuela. Results: The women were mostly between 20 and 45 years old, in 25% of them IgG antibodies to C. trachomatis were detected and in 84% of these the infection was confirmed by PCR, in none of the women IgM antibodies to C. trachomatis were found. Conclusion: Chronic infection characterizes women between 20 and 45 years of age; the immunoenzymatic test yielded false positives corroborated by PCR.

Abstract Background: Chlamydia trachomatis-lymphogranuloma venereum (LGV) is a sexually transmitted infection (STI) and an uncommon cause of proctitis. The diagnosis requires a high index of clinical suspicion, since the clinical, imaging, endoscopic, and histological findings can mimic multiple benign or malignant conditions like inflammatory bowel disease and rectal neoplasms. Case Presentation: We present the case of a 48-year-old Caucasian male with no significant previous medical history who was admitted due to the suspicion of a rectal neoplasia. He underwent an abdominopelvic computed tomography (CT) scan and pelvic magnetic resonance imaging (MRI) before admission due to complaints of anorectal pain, hematochezia, and constipation over the previous 2 weeks. The examination revealed a circumferential rectal wall thickening, infiltration of the perirectal fat and invasion of the mesorectal fascia, associated with perirectal fat lymphadenopathy. A radiological diagnosis of a rectal malignant neoplasia staged as T4N2MX was stated. Digital rectal examination identified a circumferential rectal tumor. Rectosigmoidoscopy showed an extensive and circumferential ulceration of the rectal mucosa, with elevated geographical borders, exudate, and aphthoid erosions at the proximal limit of the endoscopic mucosal ulceration. Biopsy specimens revealed acute ulcerative proctitis with lymphoplasmocytic inflammatory infiltrate but no evidence of dysplasia or malignancy. A STI screening was positive for HIV-1 (CD4+ 251/mm3; N = 700-1,100) and C. trachomatis, with an elevated IgA-specific antibody titer (52.000; N < 5.0), suggesting LGV disease. The diagnosis was confirmed by the identification of C. trachomatis DNA on rectal swab. Other infectious causes of acute proctitis were excluded. When faced with these results, the patient ended up mentioning that he had unprotected anal sex with men. He started treatment with doxycycline 100 mg twice a day for 21 days, with a drastic improvement. Rectosigmoidoscopy was repeated and showed clear signs of progressive resolution of the ulcerative proctitis. Discussion: LGV-associated proctitis, often undervalued, is a reemerging disease which should always be considered a benign cause of rectal mass, in order to avoid delay in diagnosis and development of complications. Diagnosis becomes more challenging in patients with unknown HIV status. A detailed clinical history, including sexual behaviors, is a vital step to achieve the final diagnosis.

Resumo Introdução: A infeção por Chlamydia trachomatis-linfogranuloma venéreo (LGV) é uma doença sexualmente transmissível (DST), sendo uma causa incomum de proctite. O diagnóstico exige um elevado grau de suspeição, dado que os achados clínicos, radiológicos, endoscópicos e histológicos podem mimetizar múltiplas condições benignas ou malignas, como a doença inflamatória intestinal e as neoplasias retais. Caso clínico: Apresentamos o caso de um homem de 48 anos, caucasiano, sem antecedentes relevantes, admitido por suspeita de neoplasia retal. Por queixas de dor anorretal, hematoquézias e obstipação com 2 semanas de evolução, realizou uma tomografia computadorizada abdominopélvica e uma ressonância magnética pélvica, que revelaram espessamento retal circunferencial, infiltração da gordura periretal e invasão da fáscia mesoretal, associados a linfadenopatias locais, sugestivos de malignidade retal (T4N2MX). O toque retal identificou uma tumoração retal circunferencial. A retosigmoidoscopia mostrou mucosa retal com ulceração extensa e circunferencial, bordos geográficos elevados, exsudado e erosões aftóides no limite proximal da ulceração mucosa. As biópsias revelaram proctite ulcerada aguda com infiltrado linfoplasmocitário difuso, sem displasia ou neoplasia. O screening de DST foi positivo para VIH-1 (CD4+ 251/mm3; N:700-1100) e título elevado de IgA para C. trachomatis (52 000; N<5), sugerindo LGV. O diagnóstico foi confirmado pela identificação do DNA de C. trachomatis em zaragatoa retal. Outras causas infecciosas de proctite aguda foram excluídas. Perante estes resultados, o doente acabou por mencionar que tinha tido relações homossexuais anais desprotegidas. Iniciou doxiciclina (100 mg duas vezes por dia, por 21 dias) com melhoria sintomática drástica. Repetiu retosigmoidoscopia, com sinais de proctite ulcerada em resolução. Discussão: A proctite por LGV, frequentemente desvalorizada, é uma doença re-emergente, que deve ser sempre equacionada como causa benigna de massa retal, de modo a evitar o atraso diagnóstico e o desenvolvimento de complicações. O diagnóstico torna-se mais desafiante em doentes com status VIH desconhecido. A história clínica detalhada, incluindo comportamentos sexuais de risco, é fundamental para o diagnóstico.

Resumo O impacto da infecção por Chlamydia trachomatis (CT) na fertilidade feminina ainda não está completamente estabelecido, uma vez que o nível de evidência associando esses fatores ainda é insignificante. Assim, o objetivo desta revisão é contribuir para uma melhor elucidação deste assunto. A base de dados eletrônica escolhida foi a Medline/PubMed, com a última pesquisa em 11 de maio de 2021. Utilizou-se como filtro a data de publicação, sendo selecionados os 5 anos anteriores. Foram usados os seguintes descritores: Chlamydia trachomatis E infertility; Chlamydia trachomatis E tubal alteration E infertility; Chlamydia E low pregnancy rates. Dos 322 estudos selecionados, 293 que não atenderam aos nossos critérios de elegibilidade foram excluídos. Posteriormente, retiramos sete estudos por não terem como foco principal a possível correlação entre infecção por CT e infertilidade feminina e três por tratarem de infecções sexualmente transmissíveis (ISTs) em geral. Além disso, dois estudos concebidos como revisões também foram excluídos. Portanto, incluímos 17 estudos em nossa análise qualitativa. Os autores realizaram pesquisas individualmente e analisaram criteriosamente os estudos selecionados. Como obtivemos as informações necessárias para nosso estudo por meio da leitura dos textos, nenhum contato foi feito com os autores. Esta revisão sistemática corrobora a hipótese de que a infecção por CT potencializa a infertilidade feminina, pois 76,47% dos estudos incluídos encontraram correlação positiva entre eles. Concluímos que existe uma associação importante entre infecção por CT e infertilidade feminina. Portanto, tornar os procedimentos de triagem por CT parte da rotina de investigação de infertilidade é relevante e justificável.

Abstract The impact of Chlamydia trachomatis (CT) infection on female’s fertility is not completely established yet, since the level of evidence associating these factors is still weak. Hence, the goal of the present review is to contribute to a better elucidation of this matter. The electronic database chosen was the Medline/PubMed, with the last survey on May 11, 2021. Publication date was used as a filter, with the previous 5 years having been selected. The following describers were used: chlamydia trachomatis AND infertility; chlamydia trachomatis AND tubal alteration AND infertility; chlamydia AND low pregnancy rates. From the 322 studies screened, 293 that failed to meet our eligibility criteria were excluded. Subsequently, we removed seven studies for not having the possible correlation between CT infections and female infertility as its main focus, and three for being about sexually transmitted infections (STIs) in general. Moreover, two studies designed as reviews were also excluded. Ergo, we included 17 studies in our qualitative analysis. The authors conducted research individually and analyzed carefully the studies selected. As we retrieved the information needed for our study through reading the texts, no contact was made with the authors of the studies selected. This systematic review corroborates the hypothesis that CT infection potentiates female infertility, as 76.47% of the included studies found a positive correlation between them. We conclude that there is an important association between CT infection and female infertility. Ergo, making CT screening part of the infertility investigation routine is relevant and has a reasonable justification.
