“…The prevalence of CT was 20.5%, close to findings in a Brazilian study carried out at an STD clinic in Manaus (12) : 20.7%. Among Indian female SW, prevalence levels were lower though, amounting to 7.8% among brothel workers (13) .…”

Changes in the profile of sexually transmitted diseases have increased the need for their detection, particularly where there is a concentration of individuals with risk behavior, so that diagnosis and immediate treatment can be translated in the reduction of resulting problems. The objective was to identify the prevalence of sexually transmitted diseases in female sex workers in a medium-sized city in São Paulo state. This population prevalence study was conducted in 2008 on 102 females. The prevalence was 71.6%. When considered separately and in association, the highest values found were: HPV (67.7%) and Chlamydia (20.5%). HPV typing showed oncogenic genotypes. The prevalence of syphilis was 4.0% and of trichomoniasis 3.0%. No cases of hepatitis B or gonorrhea were identified. It was concluded that the prevalence of sexually transmitted diseases in the studied group was high, since approximately two thirds of the women showed some type of disease under this classification. Considerados aisladamente y en asociación, los mayores valores encontrados fueron: VPH (67,7%) e infección clamidiana (20,5%). El tipaje del VPH evidenció genotipos oncogénicos. La prevalencia de sífilis fue de 4,0% y de tricomoníasis 3,0%. Ningún caso de hepatitis B o gonorrea fue identificado. Se concluye que la prevalencia de enfermedad sexualmente transmisible fue elevada, ya que aproximadamente dos tercios de las mujeres presentaban alguna enfermedad de ese tipo.

“…The frequency of Chlamydia trachomatis was 17% (12-25%) using PCR -EIA. Higher frequencies were found in the 31-40 year old subgroup (49%) and in the 20-30 year-old subgroup (33%) [20].…”

This study compares the detection rates of Chlamydia trachomatis by two techniques, direct immunofluorescence (IMF) and real time polymerase chain reaction (PCR), in patients with and without intra-epithelial cervical lesions (SIL) in Recife. We conducted a transversal study involving 35 women with SIL and 35 without SIL attended at Ambulatório Especializado da Mulher, Recife, Brazil. They were tested for Chlamydia trachomatis using two techniques, direct IMF or real time PCR. The rates of Chlamydia trachomatis detection were compared and the association with intra-epithelial cervical lesions was determined using the chi-square test at a 5% level of significance. Concordance between the tests was evaluated using kappa. The global prevalence of Chlamydia infection was 47.1% by direct IMF and 58.6% by real time PCR. A significant association was observed between Chlamydia diagnosis and presence of intra-epithelial cervical lesions, with about 80% positive results by direct IMF and 77.1% by real time PCR. However, the detected rate of infection with Chlamydia trachomatis was significantly greater in patients without intra-epithelial cervical lesions tested by real time PCR (40%) when compared to direct IMF (14.3%). The concordance between the tests was weak, with a kappa coefficient of 0.4. Both real time PCR and direct IMF detected elevated rates of Chlamydia infection in patients with intra-epithelial cervical lesions (80%) but the tests were discordant when patients without cervical lesions were tested, possibly because sensitivity of real time PCR is greater.

“…According to the reports by the Health Surveillance Secretariat, STD and AIDS Program, the overall prevalence of CT infection, in 2005, was 9.2% for both sexes and 7.3% only in women (15) . The overall rates for each of the cities participating in the study, in descending order, were: Rio de Janeiro (15%), Porto Alegre (12.2%), Vitória (10.7%), São Paulo (9.1%), Manaus (7.8%), Goiânia (7.6% in the female population and 5% in asymptomatic males), and Fortaleza (4.7% for both sexes) (15,(22)(23)(24)(25)(26) . More recent data have established a prevalence of 56.45% in the endocervical samples from 287 women in São Paulo and Santa Catarina by the PCR method (27) .…”

ARTICLE INTRODUCTIONThe WHO estimates that there are 105.7 million new cases of Chlamydia worldwide, with 3 to 4 million of these only in the United States of America (USA), with over 1.4 million cases reported in 2011 (1)(2)(3)(4)(5) , 5 million in Eastern Europe, and 34 million in subSaharan Africa and southeast Asia (5)(6)(7)(8)(9) . Worldwide, it occurs more frequently in sexually active young adults, generally aged younger than 20 years, and it is nearly three times higher in the 14-24 years age group (5,7,9,10) . It currently represents the leading cause of female infertility, but the most common infections are urethritis and cervicitis, which, if untreated, can lead to serious consequences in the reproductive tract such as ectopic pregnancy and infertility (6,(8)(9)(10) . About 50% of infected men and 70 to 75% of infected women are asymptomatic. The infection is transmitted during sexual contact and to the newborn at birth and may cause neonatal conjunctivitis or pneumonia (5,6,(8)(9)(10) . Over 100 million individuals of both sexes worldwide are infected with Chlamydia at some point in their lives (6,9,10) . Among male subjects, the prevalence is comparable with that of risk populations, ranging from 15 to 20%, while in the asymptomatic population, it is between 3 and 7%. In female subjects, the infection rates of asymptomatic populations are between 3 and 10%, while in high-risk populations they are above 20% (1)
