[Current aspects of Chlamydia trachomatis infection].

The number of detection and diagnosis of urogenital infections with Chlamydia trachomatis is increasing among both men and women. Three-quarters involve young people between 15 and 24 years. Infection, often asymptomatic, is more common in women. It is necessary to identify it to avoid complications.The number of rectal lymphogranuloma venereum (LGV) is also growing. The affected patients are homo/bisexuel men frequently co-infected with HIV. Nucleic acid amplification tests (NAATs) are the tests of choice to the diagnosis of C. trachomatis infection regardless of the clinical situation. Most of tests simultaneously detect C. trachomatis and Neisseria gonorrhoeae. The recommended treatment regimens for a non-complicated infection to C. trachomatis is azithromycin 1g orally in a single dose or doxycyline 100 mg orally twice a day for 7 days. Doxycyclin for 21 days remains the treatment of choice for LGV. Patients should be instructed to refer their sex partners for treatment.
