title: [Prevalence of asymptomatic sexually transmitted infections among high-risk patients attending a free anonymous HIV-screening center].
abstract: BACKGROUND
  The aim of this study was to assess the prevalence of sexually transmitted infections among patients attending an anonymous HIV Screening Center.
  
  
  METHODS
  This prospective study was performed in the HIV Screening Center of University hospital in Reims (France) from May 1997 to December 1997. The inclusion criteria were the asymptomatic clinical presentation and the presence of risk factors for sexually transmitted infections referring to WHO criteria. The methods included clinical examination after application of acetic acid and urethral and endocervical swabs to identify:Neisseria gonorrhoeae, Chlamydia trachomatis, Ureaplasma urealyticum, Mycoplasma hominis, Gardnerella vaginalis, Trichomonas vaginalis in specific culture. Treponema pallidum and HIV-1 infection were both detected by Enzym Linked Immuno Sorbent Assay (ELISA).
  
  
  RESULTS
  One hundred and one patients (62 men and 39 women) were included in the study. Their mean age was 27 +/- 4 Years. Risk factors for sexually transmitted infections were: multiple sexual partners 81 p. 100; homo or bisexuality 16 p. 100; intravenous drug use 3 p. 100. The sexually transmitted infections were: HIV-1 infection 1 p. 100;Ureaplasma urealyticum 25 p. 100; genital warts 5 p. 100;Chlamydia trachomatis 3 p. 100; Gardnerella vaginalis 3 p. 100; Mycoplasma hominis 2 p. 100; Treponema pallidum 0 p. 100; Neisseria gonorrhoeae 0 p. 100; Trichomonas vaginalis 0 p. 100. The prevalence of sexually transmitted infections was significantly higher among women (p<0.05).
  
  
  CONCLUSIONS
  Classical sexually transmitted infections and HIV infection were rarely detected in this study; but prevalence of other sexually transmitted infections (genital warts, Chlamydia trachomatis, Mycoplasma hominis, Ureaplasma urealyticum) was high. Ureaplasma urealyticum is considered as a possible pathogenic agent in pregnant women (preterm delivery, decrease of birth weight, chorioamniotitis). These results suggest that other than sexually transmitted infections in high risk patients attending a HIV Screening Center other sexually transmitted infections should also be systematically screened for.
