Chlamydial lymphogranuloma (venereum)
ICD-10 A55 is a billable code used to indicate a diagnosis of chlamydial lymphogranuloma (venereum).
Chlamydial lymphogranuloma venereum (LGV) is a sexually transmitted infection caused by specific serovars of Chlamydia trachomatis. It primarily affects the lymphatic system and is characterized by the development of painful lymphadenopathy, particularly in the groin region. The infection typically begins with a small, painless ulcer at the site of infection, often on the genitalia or perianal area, which may go unnoticed. As the infection progresses, it can lead to significant swelling of the lymph nodes, known as buboes, which can become painful and may rupture. LGV is more prevalent in certain populations, particularly among men who have sex with men (MSM). Diagnosis is often made through clinical evaluation and laboratory testing, including nucleic acid amplification tests (NAATs). Treatment typically involves a course of antibiotics, with doxycycline being the first-line therapy. Early detection and treatment are crucial to prevent complications such as chronic inflammation and scarring. Contact tracing is essential to control the spread of the infection, as LGV is highly transmissible through sexual contact.
Detailed patient history, clinical findings, and laboratory test results.
Diagnosis and management of LGV in high-risk populations.
Consideration of co-infections and comprehensive STI screening.
Thorough sexual history and risk assessment.
Routine screening and treatment of STIs in sexually active individuals.
Emphasis on patient education and contact tracing.
Used for diagnosing LGV in patients presenting with symptoms.
Document the reason for testing and patient consent.
Infectious disease specialists should ensure comprehensive STI screening.
Common symptoms include a painless ulcer at the site of infection, followed by painful swelling of lymph nodes, fever, and systemic symptoms in advanced cases.
LGV is typically treated with antibiotics, with doxycycline being the first-line treatment. Alternative regimens may include azithromycin.
Contact tracing is crucial to prevent the spread of LGV, as it is highly transmissible through sexual contact. Identifying and treating partners helps control outbreaks.
