    Chlamydia trachomatis causes the most prevalent bacterial Sexual Transmitted Infection. In pregnant women, untreated chlamydial infections are associated with abortions, premature rupture of membranes, postpartum endometritis, low birth weight and transmission to the newborn. In C贸rdoba, Argentina, there is little knowledge about the prevalence of Chlamydia trachomatis in women in their third trimester of pregnancy, so, the aim of this study was to evaluate Chlamydia trachomatis prevalence and genotypes present in Cordovan pregnant women with different age and socioeconomic status. Methods and findings Design: prospective study. Settings: Women population from Cordoba city, Argentina. Population: Pregnant women having 35 to 37 weeks of gestation. Methods: Five hundred and nine cervical swabs were collected. Each sample was subjected to DNA extraction and PCR for Chlamydia trachomatis using primers NRO/NLO and CTP1/CTP2. Positives samples were sequenced to determine genotype. Main outcome measures: Demographic data of the patients were collected to detect a population at risk for this infection. Results A prevalence of 6.9% (35/509) for Chlamydia trachomatis infection was detected, with 32/ 295 and 3/214 from pregnant women with low or better economic resources respectively (p = 0,0001). Results showed a significantly increased rate of 11.6% (30/258) in women under 25 years compared with 2% (5/251) in patients over that age (p = 0,00003). Genotype E was the most prevalent. Conclusions With these results, we can say that pregnant women under 25 years old and low economic resources are one of the populations in which the screening programs of Chlamydia trachomatis should focus.Fil: Kiguen, Ana Ximena.

    Tesis - Maestr铆a en Salud P煤blica - Universidad Nacional de C贸rdoba. Facultad de Ciencias M茅dicas. Escuela de Salud P煤blica, 201684 p.Chlamydia trachomatis (C.trachomatis) produce una de las infecciones de transmisi贸n sexual (ITS) m谩s frecuentes en el mundo. Esta bacteria se asocia a abortos, endometritis posterior al parto y ruptura prematura de membranas. Cuando la infecci贸n se transmite al reci茅n nacido puede ocasionar bronquitis, neumon铆a, conjuntivitis y bajo peso. Objetivo: Determinar la prevalencia de la infecci贸n por C. trachomatis en mujeres que cursan el tercer trimestre de embarazo evaluando los factores de riesgo asociados, caracterizando a nivel molecular los genotipos presentes y analizando el costo/beneficio de la implementaci贸n del tamizaje de esta infecci贸n bacteriana. Materiales: Se procesaron 279 muestras cl铆nicas cervico-vaginales de mujeres (16 a 42 a帽os) embarazadas (de 35-37 semanas de gestaci贸n), que concurr铆an al Laboratorio de la Direcci贸n de Especialidades M茅dicas a realizarse el estudio de portaci贸n de Streptococcus agalactiae, entre septiembre y diciembre de 2013. M茅todos: La detecci贸n de C. trachomatis fue realizada por biolog铆a molecular aplicando la reacci贸n en cadena de la polimerasa (PCR) y PCR anidada (nested PCR) dirigidas a las secuencias gen茅ticas que codifican para el pl谩smido cr铆ptico y la prote铆na mayor de membrana externa, respectivamente. La genotipificaci贸n se realiz贸 por el an谩lisis filogen茅tico de las secuencias obtenidas de la PCR gen茅rica y las secuencias patrones del GenBank.Resultados: Se detect贸 C. trachomatis en 29 (10,4%) mujeres. La distribuci贸n por grupo etario fue: 24 (82,8%) menores de 25 a帽os; 4 (13,8%) entre 26-35 a帽os y 1 (3,4%) mayor de 35 a帽os. Se evidenci贸 asociaci贸n significativa entre la detecci贸n infecci贸n de C. trachomatis en y las menores de 25 a帽os (p=0,018, X2=4,2262: OR=2,7472 1,0133-7,4480); cabe destacar que el 98% de ellas reciben asignaci贸n universal por hijo. Los genotipos encontrados fueron: B, D, E y F; siendo este 煤ltimo el m谩s frecuente. El costo de la implementaci贸n del tamizaje por biolog铆a molecular de C.trachomatis para las embarazadas; asistidas en centros de salud municipales de la Ciudad de C贸rdoba, corresponde a la cuarta parte del costo anual ocasionado s贸lo por conjuntivitis y neumon铆as de los reci茅n nacidos infectados.Discusi贸n: Este es el primer reporte de prevalencia de la infecci贸n por C. trachomatis en mujeres embarazadas (10,4%) en nuestra regi贸n. La misma result贸 ser superior a la informada en USA y Australia; ( 3,5% y 6,4% respectivamente). E en estos pa铆ses se han implementado rigurosos programas de control de esta Iinfecci贸n. Nuestro trabajo muestra que las pacientes embarazadas menores de 25 a帽os y con bajo nivel socioecon贸mico son un grupo de alto riesgo para la infecci贸n por C.trachomatis. Conclusiones: La detecci贸n de C.trachomatis y el tratamiento espec铆fico de las embarazadas y sus reci茅n nacidos producir铆a una mejor calidad de vida de ellos y un descenso del costo de las complicaciones producidas. Palabras Claves: Chlamydia trachomatis, embarazadas, genotipos, costo/beneficio, tamizaje.Chlamydia trachomatis (C. trachomatis) causes one of the most common sexually transmitted infections (STIs) in the world. This bacterium is associated with abortions, endometritis postpartum, and premature rupture of membranes. When the infection is transmitted to newborns, it may cause bronchitis, pneumonia, conjunctivitis and low weight. Objective: Determinate the prevalence of C. trachomatis infection in women on their third trimester of pregnancy, evaluating associated risk factors, characterizing the genotypes at the molecular level, analyzing the cost / benefit rate of implementing the screening of the bacterial infection. Materials: In 2013, between September and December, two hundred and seventy nine cervico-vaginal clinical women samples were taken at Laboratorio de la Direcci贸n de Especialidades M茅dicas. The pregnancy women had between 35 and 37 gestation weeks and about 16 up to 42 years old. Methods: Detection of C. trachomatis was performed by molecular biology applying the polymerase chain reaction (PCR) and nested PCR (nested PCR) directed to genetic sequences encoding the cryptic plasmid and most outer membrane protein, respectively. Genotyping was performed by phylogenetic analysis resulting from the sequences obtained of generic PCR and patterns GenBank. Results: C. trachomatis was detected in 29 (10.4%) women. The distribution by age group was 24 (82.8%) under age 25; 4 (13.8%) between 26-35 years and 1 (3.4%) over 35 years. Significant association was observed between the C. trachomatis infection and patients under 25 years (p = 0.018, X2 = 4.2262: 2.7472 OR = 1.0133 to 7.4480). The 98% of them received universal child allowance. The genotypes that were found are: B, D, E and F, being F, the most common genotype value found. The cost of implementing screening for molecular biology C.trachomatis for pregnant women, assisted in municipal health centers of the City of C贸rdoba, corresponds to a quarter of the annual cost caused only by conjunctivitis and pneumonia of newborns infected. Discussion: In our region, this is the first report on the prevalence of C. trachomatis infection in pregnant women (10.4%). It was superior to USA`s report and Australia`s report; 3.5% and 6.4% respectively. Those countries have been implemented rigorous programs to control this infection. Our work shows that pregnant patients under 25 years with low socioeconomic status are a group at high risk for infection with C. trachomatis. Conclusions: The detection of C. trachomatis and specific treatment of pregnant women and their newborns would produce a better quality of life for them and a decrease in the cost of its complications.Fil: Marram谩, Marcela.
