[Prevalence of Chlamydia trachomatis, Neisseria gonorrhoeae and Mycoplasma genitalium infections in the emergency department].Pathol Biol (Paris) 2013; 61(6):245-9PB
To estimate the prevalence of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG) and Mycoplasma genitalium (MG) in patients under 31 years of age admitted to the emergency department of the University Hospital of Montpellier, for which a urinalysis was performed.
PATIENTS AND METHODS
CT, NG and MG specific real-time PCRs were performed in the urine samples from 301 patients between July 2010 and January 2011.
CT DNA was detected in 11% of patients, NG DNA in 3.7% of patients and MG DNA in one patient. Seventy-five percent of male patients and only 13% of women were diagnosed with sexually transmitted infection (STI). No patient with leucocyturia below 10(4)/mL had a positive PCR result for one of the three bacteria. Of the patients with leucocyturia greater or equal to 10(4)/mL, CT was detected in 23.4% of men and 11% of women, NG in 19.2% of men and 1% of women, and MG in 2.1% of men.
The prevalence of NG and CT detection in our population was high while that of MG was low. The diagnosis was facilitated by the use of PCR on the urine sample although this sample is not recommended for the molecular detection of bacterial agents of STIs and may explain the low detection of MG. The study allowed diagnosing STIs in 14.3% of our patient population.
