\nLymphogranuloma venereum (LGV) is a sexually transmitted systemic infection caused by the Chlamydia trachomatis bacterium that targets the lymph nodes in the groin area. Its symptoms include small painless sores that appear in the genital area, followed by painful, tense swellings in the groin lymph nodes. Its treatment is provided through long-term antibiotic use planned under physician supervision and, when necessary, minimal clinical interventions that relieve pressure in the lymph nodes. In this condition, which progresses by infiltrating the lymphatic channels deep within the body, early diagnosis is the most critical step in preventing permanent damage to the tissues and completely eliminating the infection from the body.<\/p>\n
| Definition<\/span><\/td>\n | Lymphogranuloma venereum (LGV) is a sexually transmitted invasive infection caused by the L1, L2, and L3 serovars of the Chlamydia trachomatis bacterium. It can affect genital, anal, and lymphatic tissues; if left untreated, it may lead to chronic complications.<\/span><\/td>\n<\/tr>\n| Causative Agent<\/span><\/td>\n | Chlamydia trachomatis serovars L1, L2, and L3<\/span><\/td>\n<\/tr>\n | Route of Transmission<\/span><\/td>\n | It is transmitted through unprotected vaginal, anal, or oral sexual contact. It spreads through direct contact with infected lesions and mucous membranes.<\/span><\/td>\n<\/tr>\n | Risk Factors<\/span><\/td>\n | Unprotected sexual intercourse, multiple sexual partners, men who have sex with men (especially anal contact), HIV infection, and the presence of other sexually transmitted infections.<\/span><\/td>\n<\/tr>\n | Incubation Period<\/span><\/td>\n | Usually 3\u201330 days.<\/span><\/td>\n<\/tr>\n | Stages of the Disease<\/span><\/td>\n | Primary stage (small genital ulcer or papule), secondary stage (painful lymph node enlargement and systemic symptoms), tertiary stage (chronic inflammation, fibrosis, and lymphedema).<\/span><\/td>\n<\/tr>\n | Most Commonly Affected Areas<\/span><\/td>\n | Penis, vulva, vagina, cervix, urethra, rectum, anus, and groin lymph nodes.<\/span><\/td>\n<\/tr>\n | Primary Stage Findings<\/span><\/td>\n | A small, usually painless papule, vesicle, or superficial ulcer develops. The lesion can often heal without being noticed.<\/span><\/td>\n<\/tr>\n | Secondary Stage Findings<\/span><\/td>\n | Painful enlargement of the groin lymph nodes (bubo), fever, fatigue, muscle aches, and headache. In anal infections, rectal pain, bloody discharge, mucus in the stool, and proctocolitis may develop.<\/span><\/td>\n<\/tr>\n | Tertiary Stage Findings<\/span><\/td>\n | Chronic lymphedema, genital deformities, fibrosis, fistulas, anal narrowing, chronic proctitis, and permanent tissue damage may occur.<\/span><\/td>\n<\/tr>\n | Symptoms<\/span><\/td>\n | Genital ulcer, painful swelling in the groin, fever, fatigue, rectal pain, pain during defecation, anal discharge, bleeding, constipation, or tenesmus.<\/span><\/td>\n<\/tr>\n | Physical Examination Findings<\/span><\/td>\n | Tender and enlarged lymph nodes in the groin, fluctuant buboes, genital ulcers, inflammation in the anal region, and signs of proctitis.<\/span><\/td>\n<\/tr>\n | Diagnosis<\/span><\/td>\n | Clinical evaluation, nucleic acid amplification testing (NAAT\/PCR) for Chlamydia trachomatis, LGV serovar identification in appropriate samples, and exclusion of other sexually transmitted infections.<\/span><\/td>\n<\/tr>\n | Laboratory Findings<\/span><\/td>\n | Detection of Chlamydia trachomatis by PCR; serological tests may be helpful in some cases, but they are not diagnostic on their own.<\/span><\/td>\n<\/tr>\n | Differential Diagnosis<\/span><\/td>\n | Syphilis, genital herpes, chancroid, donovanosis, reactive lymphadenitis, anal fissure, inflammatory bowel diseases, anal cancer, and other causes of proctitis.<\/span><\/td>\n<\/tr>\n | Treatment<\/span><\/td>\n | Doxycycline therapy is the first choice. Alternatively, erythromycin or azithromycin may be used in some cases. Treatment must be arranged according to the physician’s recommendation.<\/span><\/td>\n<\/tr>\n | Duration of Treatment<\/span><\/td>\n | Standard treatment usually lasts 21 days.<\/span><\/td>\n<\/tr>\n | Surgical Intervention<\/span><\/td>\n | Aspiration may be performed when necessary for buboes. Extensive surgical drainage is generally not recommended because it may increase the risk of fistula formation.<\/span><\/td>\n<\/tr>\n | Treatment During Pregnancy<\/span><\/td>\n | Doxycycline is not used during pregnancy. The appropriate antibiotic is selected by the physician according to the pregnancy status.<\/span><\/td>\n<\/tr>\n | Complications<\/span><\/td>\n | Chronic lymphedema, genital elephantiasis, fistula formation, anal stenosis, chronic proctocolitis, genital damage that may contribute to infertility, and permanent scar tissue.<\/span><\/td>\n<\/tr>\n | Relationship with HIV<\/span><\/td>\n | It can occur together with HIV and may have a more severe or atypical course, especially in HIV-positive individuals. Genital ulcers may increase the risk of HIV transmission.<\/span><\/td>\n<\/tr>\n | Sexual Partner Management<\/span><\/td>\n | It is recommended that partners with whom sexual contact has occurred within the last 60 days be evaluated, tested, and treated when appropriate.<\/span><\/td>\n<\/tr>\n | Prevention Methods<\/span><\/td>\n | Condom use, safe sexual intercourse, regular sexual health screenings, avoiding sexual contact when symptoms develop, and early diagnosis and treatment.<\/span><\/td>\n<\/tr>\n | Follow-up<\/span><\/td>\n | Improvement of symptoms after treatment is evaluated. Retesting may be performed when necessary, and screening for other sexually transmitted infections is recommended.<\/span><\/td>\n<\/tr>\n | Recovery Process<\/span><\/td>\n | With early diagnosis and appropriate antibiotic treatment, the infection can heal completely. Fibrosis and lymphedema that develop in cases diagnosed late may be permanent.<\/span><\/td>\n<\/tr>\n | Risk of Recurrence<\/span><\/td>\n | Reinfection is possible. New unprotected sexual contact after treatment increases the risk of infection.<\/span><\/td>\n<\/tr>\n | When Should a Doctor Be Consulted?<\/span><\/td>\n | If there is a genital ulcer, painful swelling in the groin, rectal pain, anal bleeding or discharge, unexplained fever, or suspicion of a sexually transmitted infection, a healthcare facility should be consulted without delay.<\/span><\/td>\n<\/tr>\n | Prognosis<\/span><\/td>\n | The prognosis is generally good with early diagnosis and appropriate treatment. When treatment is delayed, chronic lymphatic damage, deformity, and permanent loss of function may develop.<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n | |
