Infecciones por Chlamydia trachomatis en una unidad de cuidados intensivos neonatales / Chlamydia trachomatis infections in a neonatal intensive care unit

Las infecciones por Chlamydia trachomatis han aumentado su prevalencia, especialmente en jóvenes embarazadas. Esto adquiere relevancia en pediatría por el elevado riesgo de transmisión vertical al neonato y su potencial gravedad en el lactante. Estas infecciones requieren de un alto índice de sospecha, por cuadro clínico atípico y signos radiológicos inespecíficos. Los métodos diagnósticos convencionales presentan limitaciones para su detección. Las técnicas moleculares son las recomendadas por su elevada sensibilidad, especificidad y rapidez, lo cual permite una terapéutica adecuada y oportuna. En este estudio, desarrollado en una unidad de cuidados intensivos neonatales de un hospital de alta complejidad durante 12 años, se describieron las características de la población, su presentación clínica y evolución. La detección microbiológica se realizó por métodos moleculares. Se incluyeron 29 pacientes (p) con infección por C. trachomatis (3,9% del total de muestras enviadas),13 p con infección respiratoria y 16 p con compromiso ocular. La mediana de edad fue de 19 días al momento del diagnóstico y el 65% de las gestantes tenía <25 años. Veinticuatro p (83%) eran recién nacidos a término y 23 p (79%) previamente sanos. Nueve p (31%) presentaron fiebre al momento del ingreso y 12 (41%) eosinofilia. De los 13 p con enfermedad respiratoria, 9 (69%) consultaron por tos y 11 (85%) con hipoxemia, con requerimientos de oxígeno en 8 (61%), asistencia respiratoria mecánica en 3 (23%) y uno (16%) requirió ECMO. Los hallazgos radiológicos mostraron un patrón intersticial inespecífico. Nueve p (31%) presentaron coinfección y uno falleció asociado a influenza A (AU)

The prevalence of Chlamydia trachomatis infections has increased, especially among young pregnant women. This is of particular relevance in pediatrics due to the high risk of motherto-child transmission and the potential severity of the infection in infants. A high index of suspicion is required for these infections due to the atypical clinical features and non-specific radiological signs. The usefulness of conventional diagnostic methods is limited. Molecular techniques are recommended because of their high sensitivity, specificity, and speed, allowing for adequate and timely treatment. In this 12-year study conducted in a neonatal intensive care unit of a tertiary-care hospital, patient characteristics, clinical presentation, and outcome are described. Microbiological detection was performed using molecular methods. Twenty-nine patients with C. trachomatis infection (3.9% of the total samples submitted), of whom 13 had respiratory tract infection and 16 ocular involvement, were included. The median age at diagnosis was 19 days and 65% of the mothers were <25 years old. Twenty-four p (83%) were term newborns and 23 patients (79%) were previously healthy. On admission, 9 patients (31%) had fever and 12 (41%) had eosinophilia. Of the 13 patients with respiratory tract involvement, 9 (69%) consulted for cough and 11 (85%) had hypoxemia, requiring oxygen in 8 (61%), mechanical ventilation in 3 (23%), and ECMO in 1 (16%). Radiological findings showed a nonspecific interstitial pattern. Nine patients (31%) presented with coinfection, one of whom died due to an associated influenza A infection (AU)

Antichlamydia Antibodies and Sperm Quality among Male Partners of Infertile Couples in Nigeria

: The impact of Chlamydia trachomatis on semen quality has been studied with varied results. Aim: To determine the prevalence of antichlamydial antibodies and their relationship with sperm quality among male partners of infertile couples in Enugu, South-East Nigeria. Materials and Methods: It was a cross-sectional study of infertile male partners of couples attending infertility clinics at the University of Nigeria Teaching Hospital (UNTH) Ituku-Ozalla, Enugu, Nigeria. Their sera were assayed for antichlamydial antibodies, and semen analysis and culture were done for each participant. Results: Two hundred and eighty-two (282) male partners of infertile couples were studied. Infertility was commoner among participants aged 40 years or more (45.1%) and was mainly of the "primary type" (62.1%). Antichlamydia antibody was detected in 156 (55.3%) participants and was significantly associated with sperm quality (P = 002; OR = 2.294; 95% CI = 1.36­3.88). Overall, 81 (28.7%) had abnormal sperm quality. The sperm count, progressive motility, and vitality were significantly lower in participants with abnormal sperm quality than those with normal sperm quality (P < 0.001) while morphology, volume, and liquefaction time did not differ significantly (P > 0.05). Staphylococcus aureus was the predominant organism isolated from culture (122/282, 43.3%) while Streptococcus species were the least (4/262, 1.4%). There was significantly more Staphylococcus aureus isolated from the semen of participants that were seropositive to antichlamydial antibodies than those that were seronegative (80/156, 51.3% vs. 42/126, 33.3%; OR = 2.105; 95% CI = 1.30­3.42; P = 0.003). Conclusion: The prevalence of antichlamydial antibodies among male partners of infertile couples in Enugu, Nigeria is high and there is a significant association with sperm quality, sperm count, and bacterial isolates in seminal culture. Male partners of infertile couples in Enugu should be screened for antichlamydial antibodies and appropriate treatment offered wherever indicated. There is a need for increased public awareness and advocacy campaigns on the impact of Chlamydia infection on male factor infertility. This primary preventive measure may help in reducing the burden of Chlamydia infection and male factor infertility.

Prevalencia de la infección por Chlamydia trachomatis y su potencial impacto perinatal en pacientes chilenas / Prevalence of Chlamydia trachomatis infection and a potential perinatal impact in Chilean patients

Resumen Chlamydia trachomatis es la infección de transmisión sexual bacteriana más frecuente en el mundo. Según datos de la Organización Mundial de la Salud, su prevalencia se estima alrededor de 4,2% en mujeres. Es una infección silente; sin embargo, puede desarrollar complicaciones en la fertilidad o durante el embarazo. El objetivo de esta revisión es describir la prevalencia de C. trachomatis en estudios recientes en Chile, que utilicen para su detección reacción de polimerasa en cadena (RPC), revisar las posibles complicaciones perinatales asociadas, conocer las recomendaciones de tamizaje en gestantes en otros países y discutir la necesidad de incluir en nuestro país un programa de tamizaje prenatal.

Abstract Chlamydia trachomatis is the most frequent bacterial sexually transmitted disease around the world. Estimated prevalence by WHO is 4,2% for women. Most cases are asymptomatic, but complications in fertility and during pregnancy are possible. The aim of this review is to describe the prevalence of C. trachomatis in Chilean studies using polymerase chain reaction (PCR) for detection, to describe the possible perinatal complications, to know recommendations about pregnancy screening in other countries, and to discuss the possibility of implementing in Chile.

Factores asociados a Chlamydia trachomatis en mujeres con vaginitis atendidas en atención primaria en salud / Factors associated with Chlamydia trachomatis in women with vaginitis attending in primary health care

INTRODUCCIÓN: Chlamydia trachomatis es reconocida como el agente causal de una de las infecciones de transmisión sexual (ITS) más común y curable. En mujeres, puede ser gatillante de enfermedad inflamatoria pélvica, un factor de riesgo para infertilidad o adquisición de otras ITS. OBJETIVO: Determinar C. trachomatis en mujeres con diagnóstico clínico de vaginitis asociando factores sociodemográficos, sexuales, clínicos y microbiota vaginal. PACIENTES Y MÉTODOS: Participaron 121 mujeres voluntarias > 18 años, con diagnóstico clínico de vaginitis y descarga vaginal anormal, atendidas en servicios de atención primaria en salud (APS) en Temuco-Chile. Se tomó muestra de flujo vaginal, determinándose C. trachomatis por una reacción de polimerasa en cadena convencional y microbiota vaginal por tinción de Gram. Se colectaron datos clínicos, sociodemográficos y sexuales mediante encuesta. RESULTADOS: Rango de edad 18-61 años. La frecuencia de C. trachomatis fue 14,9%. Se asoció C. trachomatis a mayor número de parejas sexuales en los últimos 5 años (p = 0,001), relaciones sexuales oral más anal (p = 0,055) y juguetes sexuales (p = 0,027). Asociación no significativa hubo con vaginosis bacteriana 31,2% (p = 0,091) e inicio de la actividad sexual < 18 años 20,6% (p = 0,07). CONCLUSIONES: Sería beneficioso incorporar en la semiología ginecológica de las mujeres atendidas en servicios de APS, los factores encontrados como favorecedores de infección por C. trachomatis, pues ello podría ayudar al manejo de esta ITS.

BACKGROUND: Chlamydia trachomatis is recognized as the causative agent of one of the most common and curable sexually transmitted infections (STIs). In women, it can be a trigger for pelvic inflammatory disease, a risk factor for infertility or acquisition of other STIs. AIM: To determine CT in women with vaginitis and associate it with sociodemographic, sexual, clinical, and vaginal microbiota factors. Methods: 121 female volunteers > 18 years of age, with a clinical diagnosis of vaginitis and abnormal vaginal discharge, attending in primary health care services (PHC) in Temuco-Chile were recluted. A vaginal discharge sample was taken, determining C. trachomatis by polymerase chain reaction and vaginal microbiota by Gram stain. Clinical, sociodemographic and sexual data were collected by survey. RESULTS: Age range was 18-61 years. The frequency of C. trachomatis was 14.9%. C. trachomatis was associated with a higher number of sexual partners in the last 5 years (p = 0.001), oral plus anal sex (p = 0.055) and sex toys (p = 0.027); there was a non-significant association with bacterial vaginosis 31.2% (p = 0.091) and initiation of sexual activity < 18 years 20.6% (p = 0.07). CONCLUSIONS: It would be beneficial to incorporate in the gynecological semiology of the women attended in PHC services, the factors found to favor C. trachomatis infection, as this could help the management of this STI.

Sexually transmitted infections among women living with HIV in a Brazilian city

ABSTRACT Background: Clinical improvements following highly active antiretroviral therapy (HAART) may increase high-risk behaviors resulting in sexually transmitted infections (STI). Optimism related to the success of HAART in slowing disease progression, reducing viral load, and improving health status might be important factors for increasing sexual risk behaviors such as less use of condoms. Objective: To determine the prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae, syphilis, hepatitis B and C, high-risk HPV, and cervical cytological abnormalities among women living with HIV (WLHIV) who attended a Reference Center for STI/AIDS in Brazil. Methods: A cross-sectional study was conducted among 151 WLHIV attending an STI Clinic in Vitória city, Brazil. A structured questionnaire, including demographic, behavioral, and clinical information, was used for data collection. Serological tests for HIV, syphilis, hepatitis C and B, CD4 counts, and viral load determination were performed. Cervical samples were collected for cytology and real-time PCR for HPV, Chlamydia, and Neisseria gonorrhoeae. Results: In this study, 59% of women had at least one diagnosed STI at the time of the first clinic visit; 31% had clinical forms of anogenital HPV, 10% syphilis, 8%Neisseria gonorrhoeae, 5.0% trichomoniasis, 3% Chlamydia trachomatis, 1% hepatitis B, and 1% hepatitis C; 6.7% of the women presented with cervical cytological abnormalities. Furthermore, 46.3% of women had HR-HPV, and 17.6% had HPV 16/18. Only 5% of the women had a CD4 count <200 cells/mm3, 61.6% had undetectable HIV viral load, and 81.3% were currently on HAART. Conclusion: A high prevalence of STI and HR-HPV infections were observed among HIV-infected women in this investigation. Prevention programs need to focus on counseling WLHIV and their regular partners with focused interventions such as couples counseling and education programs.

Resumo: O objetivo do estudo foi estimar a prevalência de infecções sexualmente transmissíveis (IST) e fatores associados sobre mulheres quilombolas no Brasil. Trata-se de estudo transversal de base populacional com mulheres quilombolas no período de março de 2017 a janeiro de 2019. Utilizou-se um questionário com informações sociodemográficas, comportamentais e clínicas. Foi realizado exame ginecológico para coleta de células cervicais para citologia oncótica e para detecção de Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis e papilomavírus humano (HPV), por meio de teste de reação em cadeia pela polimerase. Foi realizado teste rápido para HIV e sífilis. O desfecho principal foi definido como a infecção por um ou mais agentes infecciosos de transmissão sexual. Para a análise, utilizou-se o teste do qui-quadrado e regressão logística hierárquica. De um total de 380 mulheres, 352 (92,6%) foram incluídas no estudo. A prevalência de, pelo menos, uma IST foi de 18,5% (IC95%: 14,76-22,85). A maior prevalência foi de 11,1% por HPV, seguido de 6,3% por T. vaginalis e de 4,3% por C. trachomatis. Não houve nenhum caso de N. gonorrhoeae. Para o HIV, a prevalência foi de 0,3%, e de sífilis foi de 4,3%. A citologia cervicovaginal estava alterada em 7,7%. A detecção de uma ou mais IST foi significativamente associada a idade entre 25 e 44 anos (OR = 2,33; IC95%: 1,05-5,18), a consumo de álcool (OR = 1,96; IC95%: 1,06-3,64), a resultado alterado da citologia (OR = 3,96; IC95%: 1,65-9,48) e a vaginose bacteriana (OR = 3,61; IC95%: 2,01-6,47). Em mulheres quilombolas houve elevada prevalência de uma ou mais IST, o que torna importante a elaboração de estratégias de prevenção direcionadas a essas mulheres.

Abstract: The study aimed to estimate the prevalence of sexually transmissible infections (STIs) and associated factors in women in quilombola (maroon) communities in Brazil. This was a population-based cross-sectional study of quilombola women from March 2017 to January 2019. A questionnaire was used with sociodemographic, behavioral, and clinical information. A gynecological examination was performed for the collection of uterine cervical cells for oncotic cytology and the detection of Chlamydia trachomatis, Neisseria gonorrhoeae, Trichomonas vaginalis, and human papillomavirus (HPV) via polymerase chain reaction. Rapid tests for HIV and syphilis were performed. The main outcome was defined as infection with one or more sexually transmissible pathogens. The analysis used chi-square test and hierarchical logistic regression. From a total of 380 women, 352 (92.6%) were included in the study. Prevalence of at least one STI was 18.5% (95%CI: 14.76-22.85). The highest prevalence was for HPV, with 11.1%, followed by 6.3% for T. vaginalis and 4.3% for C. trachomatis. There were no cases of N. gonorrhoeae. Prevalence was 0.3% for HIV and 4.3% for syphilis. Cervical-vaginal cytology was altered in 7.7% of the women. Detection of one or more STIs was significantly associated with age 25 to 44 years (OR = 2.33; 95%CI: 1.05-5.18), alcohol consumption (OR = 1.96; 95%CI: 1.06-3.64), altered cervical cytology (OR = 3.96; 95%CI: 1.65-9.48), and bacterial vaginosis (OR = 3.61; 95%CI: 2.01-6.47). Quilombola women showed high prevalence of one or more STIs, emphasizing the importance of organizing prevention strategies targeted to these women.

Comparison of two methods for detection of Chlamydia trachomatis and Ureaplasma urealyticum in male reproductive tract / 北京大学学报(医学版)

OBJECTIVE@#To investigate the value of clinical application of simultaneous amplification and testing of RNA (SAT-RNA) for detecting Chlamydia trachomatis (CT) and Ureaplasma urealyticum (UU) by comparing with the polymerase chain reaction testing of DNA (PCR-DNA) method.@*METHODS@#Specimens from both urethra swab and the first avoid urine which should be at least one hour after the previous urination were collected from 163 men who were scheduled for in vitro fertilization and embryo transfer (IVF-ET) treatment due to female factors at Center for Reproductive Medicine, Shengjing Hospital of China Medical University during the period of April 2016 to April 2017. Among the 163 men, 109 simultaneously provided semen that was collected after 3-7 days of sexual abstinence for the testing. Urine and semen specimens were detected for CT and UU with SAT-RNA, while urethra swab specimens were detected for CT and UU with standard PCR-DNA. Detection results of the SAT-RNA were compared with those of the PCR-DNA method.@*RESULTS@#The positive rate of UU in the urethra swab detected with PCR-DNA and that of UU in the urine with SAT-RNA were 47.24% and 47.85%, respectively, and the coincidence rate was 93.25%. In addition, the positive and negative coincidence rates were 93.51% and 93.02%, respectively, and the concordance between the two methods was very good (Kappa=0.865). On the other hand, the positive rate of CT in the swab specimen tested with PCR-DNA was 3.07% and that of CT in urine with SAT-RNA was 4.29%, and the coincidence rate was 97.55%. Moreover, the positive and negative coincidence rates were 80.00% and 98.10%, respectively, and the concordance between the two methods was good (Kappa=0.654). Regarding SAT-RNA detection of UU in the urine and semen specimen of the 109 patients, the positive rates of UU in the urine and semen specimens were 50.46% and 44.95%, respectively; and the coincidence rate between the two specimens was 88.99%. In addition, the positive coincidence rate and the negative coincidence rate was 93.88% and 85.00%, respectively, and the concordance between the two specimens was good (Kappa=0.780). Similarly, SAT-RNA detection of CT in the urine and semen specimens showed the positive rate was 5.50% and 3.67%, respectively; and the two specimens showed 98.17% coincidence rate. The positive and negative coincidence rates were 100.00% and 98.10%, respectively, and the concordance was also good (Kappa=0.791).@*CONCLUSION@#SAT-RNA detection of CT and UU in the urine specimen showed good concordance with the PCR-DNA detection of CT and UU in the urethra swab specimen. In addition, the concordance was also good between the urine and semen specimens detected with SAT-RNA. These results indicate that, as a less invasive and equally accurate procedure, SAT-RNA may be more suitable for clinical application.

Brazilian protocol for sexually transmitted infections, 2020: pelvic inflammatory disease

Abstract Pelvic Inflammatory Disease is a topic included in the Clinical Protocol and Therapeutic Guidelines for Comprehensive Care for People with Sexually Transmitted Infections, published by the Brazilian Ministry of Health in 2020. Pelvic inflammatory disease is an upper female genital tract acute infection due to canalicular spread of endogenous cervicovaginal microorganisms and especially the sexually transmitted microorganisms. Standing out among the etiological agents involved are Chlamydia trachomatis and Neisseria gonorrhoeae. The main sequelae are chronic pelvic pain, infertility, and ectopic pregnancy. Clinical diagnosis is the most important practical approach. Antibiotic treatment must start immediately after the clinical suspicion. Guidelines for health service managers and health professionals on diagnostic tests, treatment, follow-up, counseling, notification, handling sexual partners and special populations are described. Given the increased availability of the molecular biology techniques in Brazil, C. trachomatis and N. gonorrhoeae screening are recommended as a disease prevention strategy.

High prevalence of Chlamydia trachomatis and Neisseria gonorrhoeae in Western French Guiana

ABSTRACT The purpose of this study was to estimate the prevalence of Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG) infections in western French Guiana and to analyze associated factors with both infections. A retrospective study was conducted in a sexually transmitted infections clinic in 2017. Women (n = 338) were tested by real-time polymerase chain reaction for vaginal, anal and throat CT and NG infections. Men (n = 192) were evaluated using urine specimens. Socio-demographic and sexual behaviour data were collected by nurses with a structured questionnaire. The prevalence of CT and NG infections among women were 24.3% and 13.3%, respectively, and 12.0% and 7.3% among men. Women aged under 25 years had a higher risk of CT and NG infections than women aged 35 years or more. Another risk factor for CT infection was low educational level, and occasional unprotected sex for NG infection. CT and NG infections were associated with reporting symptoms among men. Very high prevalences of CT and NG infections among women and men were found, which suggest that a large-scale screening strategy should be implemented in French Guiana.

Incidência de Chlamydia trachomatis em gestantes diagnosticadas com sífilis / Chlamydia trachomatis incidence on syphilis diagnosed pregnant women

De acordo com a Organização Mundial da Saúde, a cada ano, mais de 376 milhões de pessoas são infectadas pelas doenças sexualmente transmissíveis, das quais 127,2 milhões são por Chlamydia trachomatis. As infecções genitais não tratadas na gestação, principalmente as assintomáticas, podem acarretar complicações, tais como: endometrite puerperal e síndrome de Fitz-Hugh-Curtis. A pesquisa científica foi realizada com o objetivo de identificar a presença de Chlamydia trachomatis na secreção endocervical de gestantes sifilíticas, estabelecendo o perfil das gestantes a partir de informações dos possíveis sinais e sintomas durante a gravidez e hábitos gestacionais. Adotou-se como caminho metodológico a pesquisa quantitativa, descritiva, bibliográfica e laboratorial. Como resultados finais, 54% das gestantes foram diagnosticadas com Chlamydia trachomatis e 67% eram assintomáticas. Correlacionamos também que as altas taxas de infecção estão associadas com a falta de conhecimento sobre infecções sexualmente transmissíveis e suas formas de prevenção.(AU)

According to the World Health Organization, each year, more than 376 million people are infected with sexually transmitted diseases, of which 127.2 million are Chlamydia trachomatis, it is a asymptomatic disease, meaning there are no symptoms. Genital infections can lead to complications such as: puerperal endometritis and Fitz-Hugh- -Curtis syndrome. The scientific research was carried out to identify the presence of Chlamydia trachomatis in the endocervical secretion of syphilitic pregnant women. This research established a profile of pregnant women infected with Chlamydia trachomatis using information about possible signs and symptoms during pregnancy and gestational habits. It provides a methodological way to quantify and describe the laboratory research. The results showed, 54% of the pregnant women were diagnosed with Chlamydia trachomatis of which 67% were asymptomatic. We also correlate that high rates of Chlamydia trachomatis infection are associated with lack of knowledge about sexually transmitted infections and their forms of prevention.(AU)

Ascitis secundaria a chlamydia trachomatis tras procedimiento de reproducción asistida / Ascites secondary to chlamydia trachomatis after assisted reproduction procedure

El desarrollo de ascitis moderada o severa es infrecuente tras una enfermedad inflamatoria pélvica por Chlamydia trachomatis, una de las principales causas de infección de transmisión sexual a nivel mundial. Caso clínico: Paciente de 29 años que tras aborto diferido (gestación tras inseminación artificial) que inicia a las seis semanas con cuadro de dolor abdominal inespecífico y ascitis de predominio linfocitario. El diagnostico se realizo mediante PCR (Werfen®) tanto el liquido ascítico como en exudado endocervical. La paciente recibió tratamiento antibiótico con doxiciclina. Conclusión: Las enfermedades de transmisión sexual deben ser consideradas cuando se realiza un diagnóstico diferencial de una mujer sexualmente activa con dolor abdominal y ascitis, instaurar tratamiento antibiótico y evitar pruebas e intervenciones quirúrgicas innecesarias.

The development of moderate or severe ascites is infrequent after a pelvic inflammatory disease from Chlamydia trachomatis, one of the main causes of sexually transmitted infection worldwide. Clinical case: A 29-year-old patient who, after a delayed abortion (gestation after artificial insemination), started at six weeks with symptoms of non-specific abdominal pain and predominantly lymphocytic ascites. The diagnosis is made by PCR (Werfen®) both the ascitic fluid and the endocervical exudate. The patient received antibiotic treatment with doxycycline. Conclusion: Sexually transmitted diseases should be considered when making a differential diagnosis of a sexually activated woman with abdominal pain and ascites. Establishing antibiotic treatment, and avoiding unnecessary tests and surgical treatments.

Inhibition of CD96 enhances interferon-γ secretion by natural killer cells to alleviate lung injury in mice with pulmonary infection / 南方医科大学学报

OBJECTIVE@#To assess the effect of neutralizing CD96 on natural killer (NK) cell functions in mice with pulmonary infection and explore the possible mechanism.@*METHODS@#Male BALB/c mice were randomly divided into infection group (Cm group), anti-CD96 treatment group (anti-CD96 group) and control group (=5). In the former two groups, was inoculated intranasal administration to establish mouse models of pulmonary infection, and the mice in the control group received intranasal administration of the inhalation buffer. In anti-CD96 group, the mice were injected with anti-CD96 antibody intraperitoneally at the dose of 250 μg every 3 days after the infection; the mice in Cm group received intraperitoneal injections of saline. The body weight of the mice was recorded daily. The mice were sacrificed 5 days after infection, and CD96 expression was detected by quantitative real-time PCR and Western blotting. HE staining and pathological scores were used to evaluate pneumonia of the mice. The inclusion body forming units (IFUs) were detected in the lung tissue homogenates to assess lung tissue chlamydia load. Flow cytometry and ELISA were used to assess the capacity of the lung NK cells to produce interferon-γ (IFN-γ) and regulate macrophages and Th1 cells.@*RESULTS@# infection inhibited CD96 expression in NK cells of the mice. Compared with those in Cm group, the mice in antiCD96 mice showed significantly milder lung inflammation ( < 0.05) and reduced chlamydia load in the lung tissue ( < 0.05). Neutralizing CD96 with anti-CD96 significantly enhanced IFN-γ secretion by the NK cells ( < 0.05) and augmented the immunoregulatory effect of the NK cells shown by enhanced responses of the lung macrophages ( < 0.05) and Th1 cells ( < 0.05).@*CONCLUSIONS@#Inhibition of CD96 alleviates pneumonia in -infected mice possibly by enhancing IFN-γ secretion by NK cells and augmenting the immunoregulatory effect of the NK cells on innate and adaptive immunity.

Manifestaciones coloproctológicas de las infecciones de transmisión sexual ocasionadas por Chlamydia Trachomatis, Neisseria Gonorrhoeae y Treponema Pallidum. Presentación casuística / Coloproctological manifestations of sexually transmitted infections caused by Chlamydia Trachomatis, Neisseria Gonorrhoeae and Treponema Pallidum. Case presentation

Introducción: Las infecciones transmisibles sexualmente (ITS) con afectación anorrectal constituyen un desafío pues las manifestaciones producidas por Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) y Treponema pallidum (TP) son similares. Objetivo: Evaluar si las manifestaciones anorrectales debidas a CT, NG y TP asociadas al examen proctológico permiten diagnóstico certero, sin estudios complementarios. Pacientes y método: Estudio retrospectivo. Revisión de registros de pacientes atendidos en consultorio coloproctológico. Periodo: 01/08/2015-01/07/2016. Se incluyeron pacientes con diagnóstico de ITS anorrectal, excepto aquellos con HPV únicamente. A todos se les pesquisaron ITS mediante hisopado anal para CT por inmunofluorescencia y para estudio directo y cultivo de NG, VDRL para TP y además HIV. Variables: sexo, edad, HIV, sexo anal, uso de preservativo, motivo de consulta y resultado de estudios efectuados. Resultados: Treinta y cuatro pacientes (32 hombres). Edad mediana 31,5 años (rango: 19-65). Veinticinco pacientes HIV + (73,5%). Veintinueve pacientes (28 hombres) mantenían sexo anal. 91% no usaba preservativo adecuadamente. 65% tuvo una única infección (ITS pura). Se diagnosticaron 14 sífilis (8 puras), 14 clamidiasis (7 puras) y 11 gonococcias (7 puras). Co-infección entre ellas: 9% y con HPV: 26%. La úlcera fue la manifestación en 7/8 casos de sífilis puras (todas dolorosas, excepto una). El resto presentó síntomas variados (condilomas virales atípicos, secreción purulenta y proctorragia). Más del 50% de las gonococias puras (4/7) se manifestó con úlcera, sin embargo, el dolor estuvo presente siempre (8/8) y en tres se asoció secreción purulenta. En cambio, la mitad de los pacientes con clamidiasis puras, se manifestó con proctorragia causada por un tumor rectal/sigmoideo inflamatorio, clínicamente indistinguible de neoplasia maligna. Todos las sífilis y gonococias tuvieron correlato con las pruebas diagnósticas, no así las clamidiasis cuyo diagnóstico no pudo confirmarse en tres casos (37,5%), que respondieron al tratamiento empírico. Conclusión: NG y TP anorrectal provocaron mayormente síntomas similares a los de etiología no venérea y se requirió del laboratorio para el diagnóstico etiológico. La presencia de tumor con biopsia negativa para neoplasia maligna en pacientes de riesgo para ITS obliga a descartar clamidiasis. (AU)

Introduction: Sexually transmitted infections (STIs) are a challenge in medical consultation. The clinical manifestations of infection by Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Treponema pallidum ( TP) share symptoms at anorectal level. This implies the need for a high index of suspicion for diagnosis, which is based on history, physical examination and laboratory tests that not always are accurate or available . Purpose: Assess whether clinical signs of anorectal infections by CT, NG and TP associated with proctologic exams, lead to an accurate etiologic diagnosis without the help of specific laboratory studies. Patients and methods: Observational, retrospective study, based on a review of records of patients treated at the outpatient clinic of the Hospital Fernandez (City of Buenos Aires) department of coloproctology, in the period between August 2015 and July 2016. Patients who underwent STI diagnosis were all considered, but to those whose only diagnosis was infection by human papilloma virus (HPV) were excluded from the analysis. All patients were tested after the three etiologies of STI (anal swab for CT study by immunofluorescence, swabbing for direct study, and cultivation of NG and TP VDRL) and HIV. Variables analyzed: sex, age, presence of HIV infection, practice of receptive anal sex, proper use of condoms, signs and symptoms that prompted the consultation, and results of diagnostic tests. Results: 34 patients (32 men) were included. Median age 31.5 years (range: 19-65, interquartile range: 26-37). Twenty-five patients (73.5%) were HIV+. Twenty-nine patients (28 men) remained receptive anal sex. 91% did not use condoms properly. 65% of infections were pure, without other STI asociada-. 14 cases of syphilis (8 pure), 14 Chlamydia (7 pure) and 11 gonococcias (7puras), including co-infection in 9% of cases, no evidence of a more frequent another co-infection diagnosed. Co-infection with HPV was detected in 9 (26%) cases. The ulcer was the sign in 7/8 cases of pure syphilis (all painful, except one). The rest is expressed by a variety of symptoms (atypical viral warts, purulent and bloody diarrhea). Similarly, just over 50% (4/7) of pure gonococcias demonstrated ulcer, but the pain was always present (8/8 of pure gonococcias) and three associated with purulent discharge. Instead of the ten patients with pure chlamydia, 50% manifested with bloody diarrhea caused by a rectal tumor / inflammatory sigmoid, clinically indistinguishable from malignancy. All cases of syphilis and gonococcal were correlated with diagnostic tests; not those whose diagnosis of chlamydial infection (confirmed in eight and was negative in three, 37.5%) who responded to empiric treatment indicated by the clinical suspicion. Conclusion: While this is a small series, it shows that the NG and TP in the anorectal location mostly caused symptoms similar to those of non-venereal ethology most of the times, and laboratory assistance for etiologic diagnosis was required. The presence of tumor with negative biopsy for malignancy in patients at risk for STIs, leads chlamydia to be ruled out. (AU)

Conocimiento y creencias sobre infección por clamidia en población joven. Revisión narrativa / Knowledge and beliefs about chlamydia infection in a young population. Narrative review

RESUMEN Introducción: La Chlamydia trachomatis es una de las infecciones de transmisión sexual más comunes en la población menor de 25 años, causante de graves problemas para la salud pública y la calidad de vida de las personas. Objetivo: Describir el conocimiento y creencias en la población joven entre 15 y 25 años, en relación a la infección por Clamidia, enmarcado en el contexto chileno e internacional. Métodos: Revisión narrativa que incluye 14 artículos cualitativos y cuantitativos de los últimos 10 años, en idioma inglés y español. Resultados: Existe desconocimiento sobre la infección por Clamidia, en cuanto a las características clínicas, el medio de transmisión y las pruebas diagnósticas, lo que genera que la población joven subestime el riesgo percibido y aumente conductas sexuales riesgosas. Por otro lado, se observa que el conocimiento aumenta de forma proporcional a la edad de la población, nivel educacional e historia previa de ITS. Conclusión: El déficit de conocimientos frente a las conductas sexuales de riesgo en la población joven favorece a un aumento en la prevalencia la infección por Clamidia, por lo cual es de suma importancia realizar nuevos estudios con el fin de aportar datos para potenciar programas de salud orientados a la concientización de los jóvenes frente a esta infección para así lograr disminuir la incidencia de esta enfermedad y sus complicaciones.

SUMMARY Introduction: Chlamydia trachomatis is one of the most common sexually transmitted infections in the population under 25 years old, causing serious problems for public health and the people's quality of life. Objective: Describe the knowledge and beliefs in the young population between 15 and 25 years old, related to Chlamydia infection in the Chilean and international context. Methods: Narrative review that includes qualitative and quantitative articles of the last 10 years, published in English and Spanish. Results: There is a lack of knowledge about Chlamydia infection, in the clinical characteristics, the transmission, and in the diagnostic tests, which causes the young population to underestimate the perceived risk and increase risky sexual behaviors. On the other hand, it is observed that knowledge increases proportionally to the population's age, educational level, and previous history of STIs. Conclusion: The lack of knowledge about risky sexual behavior in young population increase the prevalence of Chlamydia infection, due to this generates risky behaviors in the population, due to this, it is very important to conduct new studies in order to provide data to promote health programs oriented to raising awareness of young people against this infection and thus achieve to reduce the incidence of this disease and complications.

Proctitis infecciosa por Chlamydia Trachomatis / Infectious proctitis by Chlamydia Trachomatis

Introducción: Las infecciones transmisibles sexualmente (ITS) son motivo de consulta frecuente, encontrándose Chlamydia trachomatis (CT) entre las prevalentes. Este germen provoca proctitis de diversa gravedad según el biovar involucrado. Los casos más floridos suelen ser ocasionados por el biovar LGV, responsable de la entidad linfogranuloma venéreo. Se desconocen la prevalencia de CT como causa de proctitis en Argentina y los biovares implicados. Con el objetivo de estudiar estas variables, se diseñó un protocolo para detectar y genotipificar CT en pacientes con proctitis infecciosa. Pacientes y métodos: Se incluyeron pacientes mayores de 18 años con cuadro de proctitis infecciosa atendidos en un centro público y otro privado. Se excluyeron pacientes con enfermedad inflamatoria intestinal y radioterapia pelviana. El estudio fue aprobado por un Comité de Ética y los pacientes firmaron un consentimiento informado. En las muestras de hisopado anal se realizó detección y tipificación molecular de CT. Resultados: Entre 31de agosto de 2017 y 31 de mayo de 2018, se incluyeron 56 pacientes (1 mujer, 53 hombres, 2 mujeres trans), 79% HIV+. En 29 casos (52%) se detectó CT. Todos eran hombres que tienen sexo con hombres (HSH) y refirieron practicar sexo anal u oral receptivo no protegido. La mediana de edad de este subgrupo fue de 31 años; 83% HIV+ en tratamiento antirretroviral y mediana de CD4 637 cel/mm3. La coinfección con otras ITS fue del 41% (siendo las más frecuentes HPV, gonococia y sífilis). Los motivos de consulta más frecuentes fueron proctorragia, pujo y tenesmo, proctalgia y secreción. Las manifestaciones clínicas fueron variadas: proctitis, úlcera perianal, tumor endoanal/rectal y absceso/fístula. El 86% de las proctitis correspondió al biovar LGV, siendo 62% moderadas a graves. La mediana de tiempo de evolución hasta el diagnóstico fue 21 días. Los casos más prolongados correspondieron a cuadros clínicos y endoscópicos más graves. La duración del tratamiento se adecuó al biovar involucrado. Todos los pacientes respondieron favorablemente; sin embargo, las dos fístulas perianales requirieron resolución quirúrgica. Conclusiones: Proctitis, úlceras y fístulas son manifestaciones inespecíficas; el hallazgo clínico y endoscópico per se no son suficientes para definir la etiología; sólo una anamnesis minuciosa permite presumir una ITS como agente causal. La tipificación logra definir el biovar, dato fundamental para adecuar el tratamiento, cortar la cadena de transmisión y contar con datos epidemiológicos a nivel local. Como resultado de esta investigación, el Ministerio de Salud de Nación proyectó la emisión de una alerta sobre la presencia de LGV en nuestro medio. Tipo de estudio: Observacional, transversal, analítico, multicéntrico.

Introduction: Sexually transmitted infections (STI) are a frequent reason for consultation, being Chlamydia trachomatis (CT) among the most prevalent ones. It causes proctitis of varying severity depending on the biovar involved. The most severe cases are usually caused by the LGV biovar, responsible for the entity called lymphogranuloma venereum. The prevalence of CT as a cause of proctitis in Argentina and the biovars involved are unknown. In order to study these variables, a protocol was designed to detect and genotype CT in patients with infectious proctitis. Patients and methods: Patients over 18 years old with infectious proctitis were attended in a public and private center. Patients with inflammatory bowel disease and pelvic radiation therapy were excluded. The study was approved by an Ethics Committee and the patients signed an informed consent. The detection and molecular typing of CT was performed in anal swab samples. Results: Between 31-08-2017 and 31-05-2018, 56 patients were included (1 woman, 53 men, 2 trans women), 79% HIV +. In 29 cases (52%) CT was detected. All were MSM and reported to practice unprotected receptive oral or anal sex. The median age of this subgroup was 31 years; 83% HIV + on antiretroviral treatment and median CD4 637 cel / mm3. The coinfection with other STIs was present 41% (the most frequent were HPV, gonococcal and syphilis). The most frequent symptoms were bleeding, tenesmus, proctalgia and secretion. The clinical manifestations were varied: proctitis, perianal ulcer, endoanal / rectal tumor and abscess / anal fistula. 86% of the proctitis corresponded to the LGV biovar, being 62% moderate to severe. The median time of evolution until the diagnosis was 21 days. The most prolonged cases corresponded to more severe clinical and endoscopic symptoms. The duration of the treatment was adapted to the biovar involved. All patients responded favorably; however, the two perianal fistulas required surgical resolution. Conclusions: Proctitis, ulcers and fistulas are nonspecific manifestations; the clinical and endoscopic findings per se are not sufficient to define the etiology; only a meticulous anamnesis allows us to presume an STI as a causative agent. The typification allows to define the biovar, a fundamental data to adapt the treatment, stop chain of transmission and provides local epidemiological data. As a result of this investigation, the Ministry of Health of the Argentina issued an alert about the presence of LGV in our country. Type of study: Observational, cross-sectional, analytical, multicenter study.

Síndrome de Fitz-Hugh-Curtis: hallazgo incidental durante el estudio de la infertilidad femenina / Fitz-Hugh-Curtis syndrome: incidental finding during the study of female infertility

RESUMEN La imposibilidad para concebir, después de un año de relaciones sexuales sin protección, es un término aceptado como infertilidad. Entre un 15 y un 20 % de parejas en Cuba requieren algún tipo de ayuda para lograr un hijo. La laparoscopia contrastada es uno de los estudios protocolizados que se debe realizar en la búsqueda de la etiología de esa incapacidad, sobre todo cuando se sospecha una posible causa tubo-peritoneal. El síndrome de Fitz-Hugh-Curtis o perihepatitis, consiste en una inflamación de la cápsula hepática, provocada por una infección (la más frecuente: clamidias), como manifestación extrapélvica de una enfermedad inflamatoria. Se informó el hallazgo insospechado de este síndrome durante la realización de una laparoscopia contrastada, asociada a una obstrucción bilateral de las trompas, sin síntomas clínicos, que hizo sospechar de un proceso pélvico infeccioso previo, como posible factor etiológico de la dificultad para concebir.

ABSTRACT The inability to conceive after one year of unprotected intercourse is a term accepted as infertility. In Cuba 15-20% of couples require some type of help to conceive a child. Hysterosalpingography is one of the established studies that should be performed when the etiology of this inability is sought, especially when a possible tubal-peritoneal cause is suspected. Fitz-Hugh-Curtis syndrome or perihepatitis, consists of an inflammation of the liver capsule, caused by an infection (chlamydial infection is the most common), as an extrapelvic manifestation of an inflammatory disease. The unsuspected finding of this syndrome was reported during the performance of hysterosalpingography, associated with a bilateral tubal obstruction, without clinical symptoms, which led us to suspect a previous pelvic infectious process, as a possible etiological factor of the difficulty to conceive.
