A Case of Late-Stage Lymphogranuloma Venereum in a Woman in Europe

Genital ulcers caused by sexually transmitted agents

Genital ulcers (GUs) represent a diagnostic challenge and can be secondary to neoplastic and inflammatory processes of different causes. Among those of infectious etiology, there are sexually transmitted infections (STIs), a very frequent reason for seeking the health service. The most common agents are herpes simplex virus and Treponema pallidum and, more rarely, Haemophilus ducreyi, Klebsiella granulomatis and Chlamydia trachomatis. A careful dermatological examination offers important diagnostic elements; however, atypical manifestations are very common. Distinctive characteristics of ulcers to look out for include their margin, edge, bottom, and base. Regional lymph node chain alterations should be evaluated regarding their number, size, mobility, consistency, inflammation, and pain on palpation. Diagnostic tests have variable sensitivity and specificity, and molecular tests are currently considered the reference exams. The rapid immunochromatographic tests represented a significant advance, as they can be performed with blood obtained from the digital pulp, offer results in up to 30 minutes, and do not require a laboratory structure. The treatment of persons affected by GU/STIs must be immediate, as it aims to prevent complications, as well as reduce transmission. It is not always considered that people with GUs/STIs have varying degrees of depression, anxiety, and self-reproach, with an impact on relationships. Establishing a bond and trusting the professional is essential for adherence to treatment and preventive measures that must be discussed individually.

2019 European guideline on the management of lymphogranuloma venereum

New or important issues in this updated version of the 2013 European guideline on the management of lymphogranuloma venereum (LGV): EPIDEMIOLOGY: Lymphogranuloma venereum continues to be endemic among European men who have sex with men (MSM) since 2003. Lymphogranuloma venereum infections in heterosexuals are extremely rare in Europe, and there is no evidence of transmission of LGV in the European heterosexual population.

AETIOLOGY AND TRANSMISSION

Chlamydia trachomatis serovars/genovars L2b and L2 are the causative strains in the majority of cases in Europe.

CLINICAL FEATURES

Among MSM, about 25% of the anorectal LGV infections are asymptomatic. Genital infections among MSM are rare; the ratio of genital vs. anorectal LGV infections is 1 in 15.

DIAGNOSIS

To diagnose LGV, a sample tested C. trachomatis positive with a commercial nucleic acid amplification test (NAAT) platform should be confirmed with an LGV discriminatory NAAT.

TREATMENT

Doxycycline 100 mg twice a day orally for 21 days is the recommended treatment for LGV. This same treatment is recommended also in asymptomatic patients and contacts of LGV patients. If another regimen is used, a test of cure (TOC) must be performed.

Lymphogranuloma venereum in Spain, 2005-2015: A literature review

Lymphogranuloma venereum (LGV) was an unusual disease in Europe until 2003, when several outbreaks among men who have sex with men (MSM) emerged. Since 2015, LGV has been included notifiable disease in Spain. Our aim is to review LGV cases published in Spain from 2005 to 2015. Fourteen studies met the inclusion criteria describing cases in 7autonomous regions. Most cases were MSM, Spaniards, aged between 30-45, with anorectal syndrome. L2 was the predominant serotype isolated. More than 60% of the cases among MSM were co-infected with HIV and nearly half of those reported another concurrent STI. Since the first LGV case published more than 10years ago, this disease has spread across Spain. Epidemiological and clinical characteristics of cases are similar to cases described in Europe. Implementation of national surveillance will improve information about LGV's magnitude and its evolution, key elements for its control.
