Effective Treatment of Lymphogranuloma Venereum With a 7-Day Course of Doxycycline.

BACKGROUND: Lymphogranuloma venereum (LGV) remains endemic in the United Kingdom, primarily among gay, bisexual or other men who have sex with men (GBMSM). Current treatment guidelines recommend 21 days of doxycycline, but recent evidence suggests shorter antibiotic duration is as effective. We evaluated clinical outcomes in a cohort with LGV treated with 7 days of doxycycline. METHODS: We reviewed case notes of all LGV cases at a South London sexual health service between November 2016 and September 2022, treated with only 7 days of doxycycline and anonymized data were collected from electronic patient records. RESULTS: Fifty-two individuals with detected LGV-specific DNA were treated with 7 days of doxycycline 100 mg twice daily. All were GBMSM, median age of 35 years (range, 21-64 years), 21 (40%) were living with HIV, and 18 (35%) had concomitant sexually transmitted infections. Thirty-four (65%) were asymptomatic, whereas 18 (35%) reported symptoms: 7 (13%) urethral, 11 (21%) anorectal, and 2 (4%) other symptoms. Twenty-two (42%) were prescribed additional antimicrobials; however, none were active against Chlamydia trachomatis . All 52 underwent follow-up testing (range, 4-481 days). Chlamydia trachomatis was detected in one individual, but negative for LGV-specific DNA, and so considered to be a reinfection. All other cases were C. trachomatis -negative, indicating successful LGV eradication. CONCLUSIONS: Our data support the approach of offering a 7-day doxycycline course routinely for asymptomatic or clinically mild C. trachomatis infections, and contacts of LGV infection, regardless of their LGV status. This may simplify patient management, reduce cost, and improve antimicrobial stewardship.

Clinical features and novel presentations of human monkeypox in a central London centre during the 2022 outbreak: descriptive case series.

OBJECTIVE: To characterise the clinical features of monkeypox infection in humans. DESIGN: Descriptive case series. SETTING: A regional high consequences infectious disease centre with associated primary and secondary care referrals, and affiliated sexual health centres in south London between May and July 2022. PARTICIPANTS: 197 patients with polymerase chain reaction confirmed monkeypox infection. RESULTS: The median age of participants was 38 years. All 197 participants were men, and 196 identified as gay, bisexual, or other men who have sex with men. All presented with mucocutaneous lesions, most commonly on the genitals (n=111 participants, 56.3%) or in the perianal area (n=82, 41.6%). 170 (86.3%) participants reported systemic illness. The most common systemic symptoms were fever (n=122, 61.9%), lymphadenopathy (114, 57.9%), and myalgia (n=62, 31.5%). 102/166 (61.5%) developed systemic features before the onset of mucocutaneous manifestations and 64 (38.5%) after (n=4 unknown). 27 (13.7%) presented exclusively with mucocutaneous manifestations without systemic features. 71 (36.0%) reported rectal pain, 33 (16.8%) sore throat, and 31 (15.7%) penile oedema. 27 (13.7%) had oral lesions and 9 (4.6%) had tonsillar signs. 70/195 (35.9%) participants had concomitant HIV infection. 56 (31.5%) of those screened for sexually transmitted infections had a concomitant sexually transmitted infection. Overall, 20 (10.2%) participants were admitted to hospital for the management of symptoms, most commonly rectal pain and penile swelling. CONCLUSIONS: These findings confirm the ongoing unprecedented community transmission of monkeypox virus among gay, bisexual, and other men who have sex with men seen in the UK and many other non-endemic countries. A variable temporal association was observed between mucocutaneous and systemic features, suggesting a new clinical course to the disease. New clinical presentations of monkeypox infection were identified, including rectal pain and penile oedema. These presentations should be included in public health messaging to aid early diagnosis and reduce onward transmission.
