Chlamydia trachomatis infection in infertile and pregnant women in southern Brazil

Introduction: Chlamydia trachomatis (CT) is the most prevalent sexually transmitted bacterial infection, affecting mainly young, sexually active women. Untreated infection may lead to reproductive complications due to tubal damage. Infections during pregnancy may cause preterm labor, low birth weight, perinatal death, and neonatal conjunctivitis and pneumonia. There are few data on CT infection in Brazil. The aim of this study was to determine CT prevalence in infertile and pregnant women. Methods: A cross-sectional study included 77 infertile and 60 asymptomatic pregnant women. First-void urine was tested for CT using PCR (Polymerase Chain Reaction). Blood samples were collected for CT IgG antibodies testing using indirect immunofluorescence. A questionnaire about medical, gynecological, and sexual history was completed by all participants. Results: We found statistically similar prevalence of PCR and IgG antibodies between the groups. There was a 61% prevalence of CT IgG antibodies in infertile women and 56.7% in pregnant women. PCR was positive in only one (1.3%) infertile woman and in none pregnant women. Conclusion: There is a high prevalence of CT IgG antibody in Brazilian pregnant and infertile women, but we found a low prevalence of positive PCR in the urine samples. CT antibodies were associated with sexual behavior and smoking (AU)

Tumor de células de Leydig do ovário associado a virilização em paciente na pós-menopausa / Ovarian Leydig cell tumor associated with virilization in postmenopausal patient

Tumores de células de Leydig são neoplasias de células esteroides e correspondem a menos de 0,5% dos tumores ovarianos. Ocorrem mais comumente na pós-menopausa e se apresentam com virilização em metade dos casos. Relatamos o caso de uma mulher de 53 anos com história de virilização. A investigação com ressonância magnética demonstrou altos níveis séricos de testosterona e um nódulo de 2 cm no ovário direito. A paciente foi submetida a ooforectomia bilateral, e a análise patológica confirmou o diagnóstico de tumor de células de Leydig do ovário direito. Um dia após a cirurgia, o nível sérico de testosterona se normalizou. Em quatro meses, a paciente apresentou nível sérico normal de testosterona e regressão parcial da alopecia. Em mulheres pós-menopáusicas com quadro de virilização progressiva, deve-se suspeitar de neoplasias ovarianas produtoras de andrógenos (AU)

Leydig cell tumors are tumors of the steroids cells and represent less than 0.5% of ovarian tumors. They occur most often in postmenopausal women and present with virilization in half of the cases. We report the case of a 53-year-old woman with virilization history. Magnetic resonance imaging showed high serum testosterone levels and a 2-cm nodule in the right ovary. The patient underwent bilateral oophorectomy, and the pathological analysis confirmed the diagnosis of Leydig cell tumor in the right ovary. The day after surgery, serum testosterone level was normalized. In four months, the patient had normal serum testosterone level and partial regression of alopecia. In postmenopausal women with progressive virilization, ovarian neoplasms producing androgens should be investigated (AU)
