This study aims to assess the safety, virological, and clinical outcomes of convalescent plasma transfusion (CPT) in immunocompromised patients hospitalized for coronavirus disease 2019 (COVID-19). We conducted a retrospective multicenter cohort study that included all immunosuppressed patients with COVID-19 and RNAemia from May 2020 to March 2023 treated with CPT. We included 81 patients with hematological malignancies (HM), transplants, or autoimmune diseases (69% treated with anti-CD20).

- - The study aimed to differentiate infectious aortitis (IA) from noninfectious aortitis (NIA) by examining their clinical, biological, and radiological features, along with their outcomes in a retrospective analysis of 183 patients from 10 French centers between 2014 and 2019.
- - Results showed that 36.1% of patients had IA, primarily caused by bacteria like Enterobacterales and streptococci, while NIA was mainly due to vasculitides and idiopathic causes; IA was notably linked to a higher prevalence of aortic aneurysms and lower survival rates.
- - The study concluded that IA had significantly higher mortality compared to NIA, with effective initial antibiotic treatment being
Objectives: To describe the efficacy and safety of prolonged cefazolin course for Staphylococcus infection and the emergence of multidrug-resistant bacteria carriage after treatment.
Methods: Monocentric retrospective cohort study of patients hospitalized for blood stream infections (BSI) and osteoarticular infections (OAI) by methicillin susceptible staphylococcal species treated with cefazolin from January 2015 to July 2017. Rectal and nasal swabs were performed at cefazolin initiation and end of treatment to detect respectively methicillin resistant Staphylococcus aureus (MRSA) and extended-spectrum beta-lactamase (ESBL) producing bacteria.
