Background Chlamydia trachomatis (CT) is one of the world's most frequent sexually transmitted infections (STI), having great impact on sexual and reproductive health.

Objectives To describe clinical profile of and the prevalence of CT infection in HIV women attending the Institute of Tropical Medicine in Manaus, Amazonas, Brazil Methods: A cross-sectional study performed among women attending the AIDS clinic from March to December 2010. They were invited to take pat in the study and answered an interview including demographic, behavioural and clinical data. They underwent in a gynaecological examination where it was collect a cervical sample for diagnosing CT by hybrid capture.

Results A total of 330 women were included in the study. Median age was 32 (IQR (IQR): 27; 38) years and median of schooling 9 (IQR: 4; 11) years. Prevalence rate of CT was 4.5% (95% CI 2.3%—to 6.7%). Median of first sexual intercourse was 16 (IQR: 14; 17) years and 53.9% were married or reported a stable partner. A total of 70.9% reported regular use of condoms in the last year. Risk factors reported were: injecting drug use (1.2%), no-injecting drugs (15.2%), previous STI (32.4%), commercial sex workers (16.4%), more than one partners in the last year (12.7%) and in life (94.5%). Regarding clinical symptoms, 51.1% reported chronic pelvic pain, 55.2% vaginal discharge, 23.0% dysuria and 10.0% genital bleeding. CD4 counts were more than 500 cells/mm3 in 21.8% and viral load were less than 100 copies/mm3 in 55.2%. In the final model of logistic regression the only variable remained was having more than one partner in life.

Conclusions Health programmes need to pay attention to the need to screen for easily curable sexually transmitted infections, such as Chlamydia trachomatis, in populations that are more vulnerable and at greater risk, as women living with HIV.
