Failure on voxilaprevir, velpatasvir, sofosbuvir and efficacy of rescue therapy.

Background & Aims: There are limited data on patients with chronic HCV infection in whom combination voxilaprevir (VOX), velpatasvir (VEL), sofosbuvir (SOF) retreatment fails. Thus, we aimed to assess treatment failure and rescue treatment options in these patients.

Methods: Samples from 40 patients with HCV genotypes (GT) 1-4 in whom VOX/VEL/SOF retreatment failed were collected within the European Resistance Study Group.

[Evaluation of methods for studying susceptibility to oxacillin and penicillin in 60 Staphylococcus lugdunensis isolates].

Introduction: Staphylococcus lugdunensis is a coagulase-negative staphylococcus associated with a variety of clinical infections. In this paper we present the results of a comparative study using 4 methods to determine antimicrobial susceptibility to oxacillin and penicillin in 60 S. lugdunensis isolates.

[Microbiological diagnosis of upper respiratory tract infections].

Upper respiratory tract (URT) infections are common and account for more medical visits than any other type of infectious disease. Diagnostic procedures for the following syndromes are included in this report: Streptococcal and nonstreptococcal pharyngitis, laryngeal syndromes, otitis, sinusitis, and others caused by unusual and/or uncommon bacteria or fungi, including Lemierre's disease, Vincent's angina, pharyngeal and peritonsillar abscesses, diphtheria, candidiasis, and zygomycoses. Detailed information is provided on specimen collection and processing, selection of laboratory tests, interpretation of findings, reporting results, additional procedures for uncommon infections, and the use of new techniques.
