Ceftaroline for bloodstream infections caused by methicillin-resistant Staphylococcus aureus: a multicentre retrospective cohort study.

Objectives: To evaluate the effectiveness of ceftaroline vs. vancomycin or daptomycin in the treatment of methicillin-resistant Staphylococcus aureus bloodstream infections (BSIs) (MRSA-BSIs).

Methods: This multicentre retrospective study conducted in 15 Spanish hospitals included data from the first MRSA-BSIs of adult patients between January 2019 and December 2022.

Impact of an Intervention Program on Infections: Comparison of 2 Hospital Cohorts.

Background: infection (CDI) occurs in various contexts and care settings and is managed by multiple specialists who are not experts in its management. While there are many initiatives to improve the diagnosis and avoid overdiagnosis, there is less focus on the overall management of the infection.

Methods: We studied a cohort of patients with a positive test result for toxigenic in 2 hospitals.

Impact of antibiotic prophylaxis in second-stage surgery in joint prosthesis infection treated with two-stage exchange. A multicenter case-control study.

Introduction: After two-stage exchange due to prosthetic joint infection (PJI), the new prosthesis carries a high risk of reinfection (RePJI). There isn`t solid evidence regarding the antibiotic prophylaxis in 2nd-stage surgery. The objective of this study is to describe what antibiotic prophylaxis is used in this surgery and evaluate its impact on the risk of developing RePJI.

Bezlotoxumab during the first episode of Clostridioides difficile infection in patients at high risk of recurrence.

Purpose: To describe a cohort with a high risk of recurrence who received bezlotoxumab during the first episode of Clostridioides difficile infection (CDI) and to compare this cohort with patients with similar characteristics who did not receive the monoclonal antibody.

Methods: A prospective and multicentre study of patients with a high risk of recurrence (expected recurrence rate>35%) who were treated with bezlotoxumab during their first episode of CDI was conducted. A propensity score-matched model 1:2 was used to compare both cohorts that were weighed according to basal characteristics (hospital-acquisition, creatinine value, and fidaxomicin as a CDI treatment).

Lamivudine and Entecavir for Acute Hepatitis B: A Systematic Review and Meta-Analysis.

Background: Acute hepatitis B infection is associated with severe liver disease and chronic sequelae in some cases. The purpose of this review was to determine the efficacy of nucleoside analogues (NA) (lamivudine versus entecavir) compared to placebo or no intervention for treating acute primary HBV infection.

Methods: A meta-analysis for drug intervention was performed, following a fixed-effect model.

Description of reinfection of joint prosthesis after 2-stage replacement (infection of the 2nd stage prosthesis): A multicenter study.

Introduction: Two-stage exchange is the gold standard in the surgical management of prosthetic joint infection (PJI). However, perioperative reinfections (RePJI) can occur to newly inserted prosthesis, which highlights the importance of an adequate antibiotic prophylaxis, although there is scarce evidence in this field. Our objective was to evaluate the characteristics of RePJI, its prognosis and the antibiotic prophylaxis that is commonly used in second-stage surgery.

spp. Infections after Instrumented Spine Surgery Have a Good Prognosis Regardless of Rifampin Use: A Cross-Sectional Study.

Infection after spinal instrumentation (IASI) by spp. is being more frequently reported. The aim of this study was to analyse the incidence, risk factors, clinical characteristics, and outcome of a spp.

Conventional versus extended-pulsed fidaxomicin dosing in patients at high risk of recurrence of Clostridioides difficile infection: a propensity score analysis.

Introduction: The main challenge in the treatment of Clostridioides difficile infection (CDI) is to reduce recurrence rates. Fidaxomicin improves the recurrence rate of CDI compared with vancomycin. Extended-pulsed dosing of fidaxomicin was associated with lower recurrence rates in one clinical trial but has never been directly compared with conventional fidaxomicin dosing.

Rates and Predictors of Treatment Failure in Staphylococcus aureus Prosthetic Joint Infections According to Different Management Strategies: A Multinational Cohort Study-The ARTHR-IS Study Group.

Introduction: Guidelines have improved the management of prosthetic joint infections (PJI). However, it is necessary to reassess the incidence and risk factors for treatment failure (TF) of Staphylococcus aureus PJI (SA-PJI) including functional loss, which has so far been neglected as an outcome.

Methods: A retrospective cohort study of SA-PJI was performed in 19 European hospitals between 2014 and 2016.

Preoperative and perioperative risk factors, and risk score development for prosthetic joint infection due to Staphylococcus aureus: a multinational matched case-control study.

Objectives: We aim to identify the preoperative and perioperative risk factors associated with post-surgical Staphylococcus aureus prosthetic joint infections (PJI) and to develop and validate risk-scoring systems, to allow a better identification of high-risk patients for more efficient targeted interventions.

Methods: We performed a multicenter matched case-control study of patients who underwent a primary hip and knee arthroplasty from 2014 to 2016. Two multivariable models by logistic regression were performed, one for the preoperative and one for perioperative variables; predictive scores also were developed and validated in an external cohort.

Fidaxomicin monotherapy versus standard therapy combined with bezlotoxumab for treating patients with Clostridioides difficile infection at high risk of recurrence: a matched cohort study.

Background: Both fidaxomicin and bezlotoxumab (used in combination with an antibiotic against Clostridioides difficile) achieve reductions in recurrence rates of C. difficile infection (CDI). However, the two strategies have never been compared.

Prognosis of unexpected positive intraoperative cultures in arthroplasty revision: A large multicenter cohort.

Background: The positive-intraoperative-cultures-type prosthetic joint infection (PIOC-PJI) is considered when surgical cultures yield microorganisms in presumed aseptic arthroplasty revisions. Herein we assess the risk factors for failure in the largest cohort of PIOC-PJI patients reported to date.

Methods: A retrospective, observational, multicenter study was performed during 2007-2017.

The efficacy of suppressive antibiotic treatment in patients managed non-operatively for periprosthetic joint infection and a draining sinus.

: Patients with prosthetic joint infections (PJIs) not suitable for curative surgery may benefit from suppressive antibiotic therapy (SAT). However, the usefulness of SAT in cases with a draining sinus has never been investigated. : A multicentre, retrospective observational cohort study was performed in which patients with a PJI and a sinus tract were eligible for inclusion if managed conservatively and if sufficient follow-up data were available (i.

Carbapenemase-producing infections in COVID-19 patients.

Background: Carbapenemase-producing (CPE) infections have been occasionally described in patients with coronavirus disease-19 (COVID-19). We assess the clinical features and outcome of these infections.

Methods: In this retrospective single-centre, case-control study, we included 54 patients with CPE infection: 30 case-patients (COVID-19) and 24 controls (non-COVID-19), collected between March and May 2020.

Suppressive Antibiotic Treatment in Prosthetic Joint Infections: A Perspective.

The treatment of prosthetic joint infections (PJIs) is a complex matter in which surgical, microbiological and pharmacological aspects must be integrated and, above all, placed in the context of each patient to make the best decision. Sometimes it is not possible to offer curative treatment of the infection, and in other cases, the probability that the surgery performed will be successful is considered very low. Therefore, indefinite administration of antibiotics with the intention of "suppressing" the course of the infection becomes useful.

Usefulness of Fecal Calprotectin in the Management of Patients with Toxigenic .

The availability of highly sensitive molecular tests for the detection of in feces leads to overtreatment of patients who are probably only colonized. In this prospective study, the usefulness of fecal calprotectin (fCP) is evaluated in a cohort of patients with detection of toxigenic in feces. Patients were classified by an infectious diseases consultant blinded to fCP results into three groups-group I, presumed infection (CDI); group II, doubtful but treated CDI; and group III, presumed colonization or self-limited CDI not needing treatment.

Prosthetic Shoulder Joint Infection by : Does Rifampin Improve Prognosis? A Retrospective, Multicenter, Observational Study.

This retrospective, multicenter observational study aimed to describe the outcomes of surgical and medical treatment of -related prosthetic joint infection (PJI) and the potential benefit of rifampin-based therapies. Patients with -related PJI who were diagnosed and treated between January 2003 and December 2016 were included. We analyzed 44 patients with -related PJI (median age, 67.

Role of asymptomatic bacteriuria on early periprosthetic joint infection after hip hemiarthroplasty. BARIFER randomized clinical trial.

Purpose: To evaluate preoperative asymptomatic bacteriuria (ASB) treatment to reduce early-periprosthetic joint infections (early-PJIs) after hip hemiarthroplasty (HHA) for fracture.

Methods: Open-label, multicenter RCT comparing fosfomycin-trometamol versus no intervention with a parallel follow-up cohort without ASB.

Primary Outcome: early-PJI after HHA.

Efficacy and safety of oral fosfomycin for asymptomatic bacteriuria in kidney transplant recipients: Results from a Spanish multicenter cohort.

Current guidelines recommend against systematic screening or treating asymptomatic bacteriuria (AB) among kidney transplant (KT) recipients, although the evidence regarding episodes occurring early after transplantation or in the presence of anatomical abnormalities is inconclusive. Oral fosfomycin may constitute a good option for the treatment of post-transplant AB, particularly due to the emergence of multidrug-resistant (MDR) uropathogens. Available clinical evidence supporting its use in this specific setting, however, remains scarce.

Infections after spine instrumentation: effectiveness of short antibiotic treatment in a large multicentre cohort.

Background And Objectives: Available information about infection after spine instrumentation (IASI) and its management are scarce. We aimed to analyse DAIR (debridement, antibiotics and implant retention) prognosis and evaluate effectiveness of short antibiotic courses on early forms.

Methods: Multicentre retrospective study of patients with IASI managed surgically (January 2010-December 2016).

Extraintestinal Clostridioides difficile infection: Septic arthritis 12 months after colitis.

A 79-year-old male was diagnosed with a total knee prosthetic infection. He had a history of an episode of Clostridioides difficile-associated diarrhoea a year ago. Clostridioides difficile was isolated from the joint fluid and intraoperative tissue samples, and ribotyping demonstrated that the strain was the same that had caused the diarrheic episode, an infrequent ribotype (RT534).

Real-life experience with fidaxomicin in Clostridioides difficile infection: a multicentre cohort study on 244 episodes.

The high cost of fidaxomicin has restricted its use despite the benefit of a lower Clostridioides difficile infection (CDI) recurrence rate at 4 weeks of follow-up. This short follow-up represents the main limitation of pivotal clinical trials of fidaxomicin, and some recent studies question its benefits over vancomycin. Moreover, the main risk factors of recurrence after treatment with fidaxomicin remain unknown.

Long-Term Impact of Suppressive Antibiotic Therapy on Intestinal Microbiota.

The aim was to describe the safety of indefinite administration of antibiotics, the so-called suppressive antibiotic therapy (SAT) and to provide insight into their impact on gut microbiota. 17 patients with SAT were recruited, providing a fecal sample. Bacterial composition was determined by 16S rDNA massive sequencing, and their viability was explored by PCR-DGGE with and without propidium monoazide.
