“…Two reports have shown a lower prevalence rate of 0.9 % in the US [16] and Germany [17] in a population of military and adolescent students; however, higher prevalence rates (8.8%) have been reported for Chinese students [18] and young people of England (8.3%) [19]. The rate for a population who attended health care centers in Brazil showed an average prevalence rate of 11.7%, ranging from 4 to 25.7% [20,21] Infection with C. trachomatis can be asymptomatic in up to 80% of the females [22], this fact can difficult its diagnosis and detection. The asymptomatic nature of chlamydial infection makes screening essential for the control of this infection.…”

Infections by Chlamydia trachomatis are usually asymptomatic or minimally symptomatic and for this reason, diagnosis is often delayed. The aim of this study was to investigate the genotype of genital Chlamydia trachomatis infections among asymptomatic adolescent and young people. Detection and genotyping of Chlamydia trachomatis were performed with polymerase chain reaction (PCR) and restriction fragment length polymorphism analysis directly on crude cells of first-void urine. Crude samples (n=427; 222 men/205 women) from young people with different social and economic conditions were screened for C. trachomatis. The prevalence of chlamydial infection was 13.7% among women and 4.1% among men. Socioeconomically disadvantaged women had a significantly higher prevalence compared with the rest of the women 27.4% vs. 6.1% (p=0.0006). Genotype E was the most frequently found (N=27 73%) among both genders. Screening programs focussed on sexually active adolescents and young people attending health clinics are important for detection of Chlamydia trachomatis infections.

Background Chlamydia, caused by the bacterium Chlamydia trachomatis(C. trachomatis), is the most common sexually transmitted disease. The incidence is not clear due to the asymptomatic nature of early stage of infections. The incidence of Chlamydia has not been fully investigated in the Chinese Han population. Since chronic infection with can C. trachomatis can lead to infertility in males and females, it is important to determine the impact of infection on clinical outcomes. The aim of this study is to explore the epidemiology of C. trachomatis in subfertile couples and to determine whether infections will adversely affect clinical outcomes after assisted reproduction technique (ART) treatment.MethodsSubfertile patients (n = 30760) were screened in the research for C. trachomatis in our center from January 2010 to December 2014. C. trachomatis-specific DNA was detected by Taq-man PCR from semen or swabs from the urethral, endocervix or vaginal. The control group consisted of 1140 subfertile patients without C. trachomatis infection. The prevalence and characteristics of C. trachomatis were identified for subfertile couples and clinical outcomes were collected and analyzed. A retrospective study was performed.ResultsNine hundred and seventy patients were diagnosed with C. trachomatis infection, and the overall prevalence was 3.15% in the most recent five years, with a yearly increasing. The incidence was a higher in the second half of the year (3.40%) compared to the first half (2.69%). The age group with the highest-risk of infection with C. trachomatis was between 26 to 35 years old, and in about one third of the couples, both partners were infected. The basic parameters and clinical outcomes were not statistically significant between different the groups (P > 0.05), even though some minor data were different (P < 0.05).Conclusions C. trachomatis is a common infection in subfertile people and it is essential to test for this organism in ART couples’ screening. This study identified no adverse on clinical outcomes after successful treatment of C. trachomatis infection, regardless of gender, age and number of C. trachomatis copies.

“…The lack of populational studies and organized screening programs hinder the visibility of problems. Therefore, most of the available data comes from regional investigations, which, taken together, help to understand the profile of this silent infection 4,5,6,7,8,9 .…”

Prevalence and Risk Factors of Chlamydia trachomatis Cervicitis in Pregnant Women at the Genital Tract Infection in Obstetrics Unit Care at Botucatu Medical School, São Paulo State University - UNESP, Brazil

Abstract: The prevalence of C. trachomatis is high in pregnant women seen at the Genital Infection Unit Care, UNESP, and is related to many risk factors. Therefore, its screening is extremely important in reducing obstetrical and neonatal complications.
