BACKGROUND: Elderly patients (aged ≥65 years) with acute myeloid leukaemia have poor outcomes and no effective standard-of-care therapy exists. Treatment with hypomethylating agents such as azacitidine and decitabine is common, but responses are modest and typically short-lived. The oral anti-apoptotic B-cell lymphoma 2 protein inhibitor, venetoclax, has shown promising single-agent activity in patients with relapsed or refractory acute myeloid leukaemia and preclinical data suggested synergy between hypomethylating agents and venetoclax, which led to this combination phase 1b study...

Acute pyelonephritis might be complicated by the formation of renal and perirenal abscesses and very rarely by renal vein thrombosis, which is a life-threatening condition. The main causative agents of acute pyelonephritis are enterobacteriaceae with the incidence of extended-spectrum beta-lactamase (ESBL)-producing strains increasing worldwide. We present the case of a 71-year-old Greek man with history of diabetes mellitus and recent hospitalization, who suffered from severe pyelonephritis with renal abscesses formation and associated bacteraemia caused by ESBL-producing Escherichia coli, complicated by extensive thrombosis of the ipsilateral renal vein and its branches, protruding also in the inferior venal cava...

Rothia mucilaginosa, previously known as Stomatococcus mucilaginosus, is a Gram-positive coccus that is part of the oropharyngeal microbiota and upper respiratory tract. It is mainly related to infections in immunosuppressed patients. Given its complex microbiological identification, its prevalence may be underestimated. We describe in this article a case of bacteraemia by Rothia in an immunocompetent paediatric patient without epidemiological or medical relevant history. In the available literature no cases of bacteraemia by Rothia mucilaginosa in immunocompetent paediatric patients have been reported...

BACKGROUND: Staphylococcus aureus bacteraemia is a common cause of severe community-acquired and hospital-acquired infection worldwide. We tested the hypothesis that adjunctive rifampicin would reduce bacteriologically confirmed treatment failure or disease recurrence, or death, by enhancing early S aureus killing, sterilising infected foci and blood faster, and reducing risks of dissemination and metastatic infection. METHODS: In this multicentre, randomised, double-blind, placebo-controlled trial, adults (≥18 years) with S aureus bacteraemia who had received ≤96 h of active antibiotic therapy were recruited from 29 UK hospitals...

Background: Patients with end-stage renal disease (ESRD) requiring intermittent haemodialysis (IHD) are at high risk of MRSA bacteraemia (MRSA-B) and often fail first-line therapy. The safety, effectiveness and optimal dosing of telavancin for MRSA-B in this patient population are unclear. Objectives: We aimed to describe clinical outcomes of telavancin in the treatment of refractory MRSA-B in patients with ESRD requiring IHD. Patients and methods: This was a retrospective study of hospitalized patients at two tertiary care academic medical centres with recurrent or persistent (≥3 days) MRSA-B treated with telavancin monotherapy...

INTRODUCTION: Community-acquired Staphylococcus aureus (SA) bacteraemia is a common cause of hospitalisation in children. The occurrence of secondary foci (SF) of SA infection is associated with higher morbidity and mortality. OBJECTIVES: To identify risk factors for SF of infection in children with community-acquired SA bacteraemia. MATERIAL AND METHODS: Prospective cohort. All children aged from 30 days to 16 years admitted to a paediatric referral hospital between January 2010 and December 2016 for community-acquired infections, with SA isolated in blood cultures, were included...

Background: Cephalosporin resistance in clinical E. coli isolates is increasing internationally. The increase has been caused by virulent and often multidrug-resistant clones, especially the extended spectrum β-lactamase (ESBL) producing E. coli clone O25b-ST131. Methods: In Norway, recommended empirical treatment of sepsis consists of gentamicin and penicillin combined, or a broad-spectrum cephalosporin. To investigate if increased gentamicin and cephalosporins resistance rates in our hospital could be caused by specific clones, we conducted a retrospective study on E...

Most Staphylococcus aureus isolates can cause invasive disease given the right circumstances, but it is unknown if some isolates are more likely to cause severe infections than others. S. aureus bloodstream isolates from 120 patients with definite infective endocarditis and 121 with S. aureus bacteraemia without infective endocarditis underwent whole-genome sequencing. Genome-wide association analysis was performed using a variety of bioinformatics approaches including SNP analysis, accessory genome analysis and k-mer based analysis...

Autoimmune Haemolytic Anaemias (AIHAs) are rare in children. They can be either a primary disease or secondary to/triggered by a host of other clinical conditions. We present five interesting cases of paediatric AIHA associated with infections (viral, bacterial and atypical) and autoimmune diseases {Systemic Lupus Erythematosus (SLE) and Autoimmune Hepatitis (AIH)}. The H1N1 influenza associated AIHA responded to oseltamivir and Intravenous Immunoglobulin (IvIg) while the cases secondary to Mycoplasma pneumoniae and pneumococcal bacteraemia required only treatment of the primary infection...
