Abstract

BackgroundWe evaluated LGV prevalence and predictors in a high risk population attending a STI Outpatients Clinic in the North of Italy.

MethodsA total of 108 patients 99 MSM and 9 women, with a history of unsafe anal sexual intercourses, were enrolled. Anorectal swabs and urine samples were tested for Chlamydia trachomatis CT DNA detection by Versant CT-GC DNA 1.0 Assay Siemens Healthcare Diagnostics Terrytown, USA. RFLP analysis was used for CT molecular typing.

ResultsL2 CT genotype was identified in 13-108 12% rectal swabs. All LGV cases were from MSM, declaring high-risk sexual behaviour and complaining anorectal symptoms. Patients first attending the STI Outpatient Clinic received a significant earlier LGV diagnosis than those first seeking care from general practitioners or gastroenterologists P = 0.0046.

LGV prevalence and characteristics found in our population are in agreement with international reports. Statistical analysis showed that LGV positive patients were older P = 0.0008 and presented more STIs P = 0.0023 than LGV negative ones, in particular due to syphilis P < 0.001, HIV P < 0.001 and HBV P = 0.001.

Multivariate logistic regression analysis revealed that HIV and syphilis infections are strong risk factors for LGV presence respectively, P = 0.001 and P = 0.010.

ConclusionsEven if our results do not provide sufficient evidence to recommend routine screening of anorectal swabs in high-risk population, they strongly suggest to perform CT NAAT tests and genotyping on rectal specimens in presence of ulcerative proctitis in HIV and-or syphilis-positive MSM. In this context, CT DNA detection by Versant CT-GC DNA 1.0 Assay, followed by RFLP analysis for molecular typing demonstrated to be an excellent diagnostic algorithm for LGV identification.
