LGV (Lymphogranuloma Venereum) Treatment in Nepal The L-Serovar Chlamydia — the Systemic Disease
The LGV is the invasive chlamydia-serovar (L1/L2/L3) disease — the transient genital ulcer plus the painful inguinal/rectal lymphadenopathy. It needs the extended 21-day doxycycline course. At Thamel Clinic.

LGV in Nepal
- Under-recognized — the LGV missed as the routine STI.
- MSM proctitis — the rectal-LGV is the emerging.
- Differential — the inguinal swelling mimics the other causes.
- Extended course — the LGV needs the 21-day, not the single-dose.
The LGV Is the Invasive Chlamydia — Distinct and Under-Diagnosed
The LGV is caused by the invasive L1/L2/L3 serovars of Chlamydia trachomatis — distinct from the routine genital chlamydia. The classic picture: a small, painless, transient genital ulcer (often missed) followed weeks later by the painful inguinal lymph-node swelling (the "buboes") — and in the receptive-anal-intercourse patients, the proctitis/rectal disease. The LGV is the under-diagnosed, increasingly-recognized infection, particularly in the MSM population.
The LGV is more invasive than the routine chlamydia — it involves the lymphatic tissue, can cause the chronic proctitis, the fistulae, the rectal stricture if the untreated. The correct recognition (the stage, the rectal involvement) and the extended antibiotic course are essential.
This page covers the LGV — the clinical stages, the diagnostic approach, the correct extended treatment, and the partner management.
The LGV Clinical Stages
Stage 1
The small painless genital ulcer — the transient, often missed.
Stage 2
The painful inguinal lymphadenopathy — the "buboes"; or the proctitis (the rectal LGV).
Stage 3
The chronic — the stricture, the fistula, the tissue damage if untreated.
Systemic
The fever, the malaise — the lymphatic involvement.
The LGV Diagnosis
The LGV is diagnosed by the site-specific NAAT (the rectal or the genital swab) detecting the C. trachomatis, ideally with the LGV-serovar genotyping. The clinical suspicion — the inguinal buboes, the proctitis in the receptive partner — plus the positive chlamydia-NAAT at the site is the diagnostic. The routine NAAT detects the organism; the serovar-typing confirms the LGV.
The blood-test or the urine test misses the LGV — the correct site-specific sample (the rectal for the receptive-anal-intercourse patient) is essential.
The LGV Treatment
The LGV requires the extended antibiotic — the doxycycline 100 mg twice daily for 21 days (the standard course — longer than the routine chlamydia 7-day). The extended course is essential because the LGV involves the lymphatic tissue, which clears the more slowly.
The alternative is the erythromycin (the pregnancy-compatible). The partner management — the partner within the window tested and the treated. The avoid-sex until the treatment complete.
The Rectal LGV and the Complications
The rectal LGV (the receptive anal intercourse) causes the proctitis — the rectal pain, the discharge, the bleeding, the tenesmus. The untreated rectal LGV can cause the chronic proctitis, the fistulae, the rectal stricture — the serious complications. The early recognition and the extended treatment prevent this.
LGV Diagnosis & Treatment Costs
| Service | What It Includes | Cost (NPR) |
|---|---|---|
| Consultation | The examination + the assessment. | Rs. 450 |
| Site-specific NAAT | The rectal/genital chlamydia PCR. | Lab rates |
| Treatment | The 21-day doxycycline + the follow-up. | Medication |
Extended course.
Why the LGV Care Here
- Recognized — the under-diagnosed identified.
- Site-specific — the correct sample.
- Extended course — the 21-day correctly given.
- Complications prevented — the early treatment.
- Confidential — the non-judgmental.
Frequently Asked Questions
What is LGV?
The invasive chlamydia-serovar (L1/L2/L3) infection — the transient ulcer then the painful inguinal lymph-node swelling or the proctitis.
How is it different from chlamydia?
The LGV is the invasive serovar involving the lymphatic tissue — it needs the 21-day treatment, not the 7-day.
What is the treatment?
The doxycycline 100 mg twice daily for 21 days — the extended course.
Is the rectal LGV serious?
Yes — the untreated can cause the chronic proctitis, the fistulae, the stricture; the early treatment prevents this.
