Pathophysiology
Lymphogranuloma venereum (LGV) is a chronic (long-term) infection of the lymphatic system caused by three different types of the bacteria Chlamydia trachomatis. The bacteria spread through sexual contact. The infection is caused by a different bacteria than that which causes genital chlamydia.
Transmission
LGV is passed from person to person through direct contact with lesions, ulcers or other area where the bacteria is located. Transmission of the organism occurs during sexual penetration (vaginal, oral, or anal) and may also occur via skin to skin contact. The likelihood of LGV infection following an exposure is unknown, but it is considered less infectious than some other STDs. A person who has had sexual contact with a LGV-infected partner within 60 days of symptom onset should be examined, tested for urethral or cervical chlamydial infection, and treated with doxycycline, twice daily for 7 days.
The clinical manifestation of LGV depends on the site of entry of the infectious organism (the sex contact site) and the stage of disease progression. Inoculation at the mucous lining of external sex organs (penis and vagina) can lead to the inguinal syndrome named after the formation of buboes or abscesses in the groin (inguinal) region where draining lymph nodes are located. The rectal syndrome arises if the infection takes place via the rectal mucosa (through anal sex) and is mainly characterized by proctocolitis symptoms. The pharyngeal syndrome is rare, starts after infection of pharyngeal tissue and buboes in the neck region can occur.
