Observational StudyPredictive factors of hepatitis C virus eradication after interferon-free therapy in HIV coinfection.
Real-life cohorts have shown that the effectiveness of all-oral, direct-acting antivirals (DAA) for HCV treatment is > 90%. We aimed to explore the predictive factors of DAA success in HIV coinfection. This is an observational prospective study within the cohort "VIH-DOC", Madrid, Spain. ⋯ DAA for HCV in HIV-coinfected patients is highly effective. DAA adherence ≥ 95% and a baseline CD4+ count ≥ 200/μL predicted a higher probability of SVR. A lower rate of SVR was found in MSM, presumably due to a higher frequency of HCV reinfection.

Evaluation of Xpert MTB/RIF Ultra performance for pulmonary tuberculosis diagnosis on smear-negative respiratory samples in a French centre.
Tuberculosis (TB) is a worldwide public health concern, including in high-resource countries with a low prevalence of TB. Xpert MTB/RIF assay was developed to improve TB and rifampicin (RIF) resistance detection, but sensitivity remains poor on smear-negative sputum. Xpert MTB/RIF Ultra assay was designed to enhance the sensitivity of TB detection in clinical samples. ⋯ Among samples collected after treatment initiation (n = 12), sensitivity was 100%, without correlation with time to growth detection due to presence of afterglow DNA in samples. In high-resource settings, the Xpert MTB/RIF Ultra test represents a useful tool for pulmonary TB diagnosis, notably for the paucibacillary forms. Moreover, quantitative measurement of Xpert MTB/RIF Ultra could help to predict time to MTB culture positivity and be used as a quality indicator of MTB culture process.

Multicenter StudyRisk factors for carbapenem-resistant Enterobacteriaceae infections: a French case-control-control study.
This study aimed to assess characteristics associated with infections due to carbapenem-resistant Enterobacteriaceae (CRE), producing (CPE) or not producing (non-CPE) carbapenemase, among hospitalised patients in 2014-2016 in France. Case-patients with CRE were compared to two control populations. ⋯ Univariate analyses comparing separately CPE cases to controls (39 CPE vs C1 and 36 CPE vs C2) and non-CPE cases to controls (121 non-CPE vs C1 and 112 non-CPE vs C2), concomitantly with comparison of CPE to non-CPE cases showed that only CPE cases were at risk of previous travel and hospitalisation abroad. This study shows that, among CRE, risk factors are different for CPE and non-CPE infection, and suggests that question patients about their medical history and lifestyle should help for early identification of patients at risk of CPE among patients with CRE.

STI with Mycoplasma genitalium-more common than Chlamydia trachomatis in patients attending youth clinics in Sweden.
The prevalence of Chlamydia trachomatis in Sweden is well known, whereas the prevalence of Mycoplasma genitalium is less well documented. Youth clinics offer free contraception advice, sexually transmitted infection (STI) testing and/or contact tracing for the age group 15-25 years. The main objective of this study was to determine the prevalence of STIs, the presence of symptoms and the role of contact tracing. ⋯ The prevalence of M. genitalium was higher than C. trachomatis in this study population. Initial testing for both C. trachomatis and M. genitalium should at least be considered for young men presenting with symptoms of genital infection. In finding positive cases, contact tracing is of great importance.

Outcomes of Clostridium difficile-suspected diarrhea in a French university hospital.
Clostridium difficile infection (CDI) produces a variety of clinical presentations ranging from mild diarrhea to severe infection with fulminant colitis, septic shock, and death. CDI puts a heavy burden on healthcare systems due to increased morbidity and mortality, and higher costs. We evaluated the clinical impact of CDI in terms of complications and mortality in a French university hospital compared with patients with diarrhea unrelated to CDI. ⋯ Death was attributable to CDI in 15 patients (6.4%). Complications are more frequent among CDI cases than in patients with diarrhea not related to C. difficile. Assessment of CDI is necessary to ensure allocation of sufficient resources to CDI prevention.
