An epidemiological survey of Mycoplasma hominis and Ureaplasma urealyticum in gynaecological outpatients, Rome, Italy.

The objective of this study was to assess the prevalence of Ureaplasma urealyticum and Mycoplasma hominis infections and to investigate associations between their presence in the lower female genital tract and lifestyle characteristics. The study was performed on a population of 3115 women, comparing the demographic and behavioural characteristics of 872 women with U. urealyticum infection and 142 women with M. hominis with uninfected women, using univariate and multiple logistic regression analysis. The prevalence of infection with U. urealyticum was 28% and M. hominis was 4.6%. In multivariate logistic regression analysis, intrauterine device, number of sexual partners and age (<35 years) were significantly associated with U. urealyticum while previous induced abortion, condom use and young age at first intercourse (<16 years) were associated with M. hominis infection. U. urealyticum infection presents the same demographic and behavioural characteristics of a sexually transmitted disease. The unprotective role of condom use suggests a non-sexual mode of transmission of M. hominis infection.

Epidemiology of Chlamydia trachomatis endocervical infection in a previously unscreened population in Rome, Italy, 2000 to 2009.

As reliable data on Chlamydia trachomatis infection in Italy are lacking and as there is no Italian screening policy, epidemiological analyses are needed to optimise effective strategies for surveillance of the infection in the country. We collected data from 6,969 sexually active women aged 15 to 55 years who underwent testing for endocervical C. trachomatis infection at the Cervico-Vaginal Pathology Unit in the Department of Gynaecology and Obstetrics of Sapienza University in Rome between 2000 and 2009. The mean prevalence of C. trachomatis endocervical infection during this period was 5.2%. Prevalence over time did not show a linear trend. Univariate analysis demonstrated a significant association of infection with multiple lifetime sexual partners, younger age (<40 years), never having been pregnant, smoking, use of oral contraceptives, and human papillomavirus and Trichomonas vaginalis infections. Multivariate stepwise logistic regression showed that T. vaginalis infection, age under 20 years and more than one lifetime sexual partner remained significantly associated with C. trachomatis infection in the final model. Prevalence of C. trachomatis in this study was high, even among women aged 25­39 years (5.1%): our data would suggest that a C. trachomatis screening policy in Italy is warranted, which could lead to a more extensive testing strategy.
