Determinants of high-grade anal intraepithelial lesions in HIV-positive men having sex with men

2018

Background Identifying determinants for histologically proven high-grade anal intraepithelial lesions (hHSIL) in HIV-positive MSM would allow better targeted screening. Methods APACHES is a prospective study of anal HPV and related-lesions in 513 HIV-positive MSM aged ≥35 in six clinics across France. At baseline, participants underwent high resolution anoscopy (HRA) with biopsy of suspicious lesions, preceded by anal swabs for liquid-based cytology, p16/Ki67 immunostaining, and HPV DNA. hHSIL diagnosis was established by histopathological review panel consensus, and determinants assessed by logistic regression. Results Baseline hHSIL prevalence was 10.4% and did not differ significantly by…

Molecular characterization of Treponema pallidum subsp. pallidum in Switzerland and France with a new multilocus sequence typing scheme

2018

Syphilis is an important public health problem and an increasing incidence has been noted in recent years. Characterization of strain diversity through molecular data plays a critical role in the epidemiological understanding of this re-emergence. We here propose a new high-resolution multilocus sequence typing (MLST) scheme for Treponema pallidum subsp. pallidum (TPA). We analyzed 30 complete and draft TPA genomes obtained directly from clinical samples or from rabbit propagated strains to identify suitable typing loci and tested the new scheme on 120 clinical samples collected in Switzerland and France. Our analyses yielded three loci with high discriminatory power: TP0136, TP0548, and TP…

Head and neck squamous cell carcinoma in people living with HIV in France.

2018

Abstract Objectives Head and neck squamous cell carcinoma (HNSCC), mainly due to smoking, is one of the leading causes of cancer deaths. However, an increasing number of tumors – especially oropharyngeal cancer – are reported in non-smokers in association with the human papillomavirus (HPV). As HIV-infected individuals are particularly at risk of HPV-related disease, we aimed to describe the burden of HNSCC in this population. Methods Retrospective chart review of patients from HIV clinics diagnosed with HNSCC between 2004 and 2014. Case patients were defined using the International Classification of Disease for Oncology (3rd edition). Age at HIV diagnosis and time from HIV diagnosis to HNS…

Staphylococcus aureus bloodstream infection in patients with prosthetic joint included in the prospective VIRSTA cohort study: frequency and time of …

2019

International audience; Among 143 patients of the VIRSTA cohort study with Staphylococcus aureus bacteremia and an arthroplasty implanted for more than a year, S. aureus periprosthetic joint infection was observed in 19%. Signs of infection (pain and swelling) were always present, in median 1 day (range, 0-21 days) after onset of bacteremia. Staphylococcus aureus has both a high potential for metastatic infection and a high affinity for foreign material. Possible prosthesis infection is of clinical concern in all patients with preexisting prosthetic materials experiencing S. aureus bloodstream infection (SAB). Prosthetic joints are especially prone to infection during the course of bacterem…
