Antibiotic nebulised

The impact of evolving treatment regimens, airway clearance strategies, and antibiotic combinations on the incidence and prevalence of respiratory infection in cystic fibrosis (CF) in children and adolescents remains unclear. The incidence, prevalence, and prescription trends from 2002 to 2019 with 18,339 airway samples were analysed. Staphylococcus aureus [- 3.86% (95% CI - 5.28-2.43)] showed the largest annual decline in incidence, followed by Haemophilus influenzae [- 3.46% (95% CI - 4...

BACKGROUND: Cystic fibrosis (CF) is a life-limiting genetic condition, affecting over 90,000 people worldwide. CF affects several organs in the body, but airway damage has the most profound impact on quality of life (QoL) and survival. Causes of lower airway infection in people with CF are, most notably, Staphylococcus aureus in the early course of the disease and Pseudomonas aeruginosa at a later stage. Macrolide antibiotics, e.g. azithromycin and clarithromycin, are usually taken orally, have a broad spectrum of action against gram-positive (e...

BACKGROUND: Nebulisation of antibiotics is a promising treatment for ventilator-associated pneumonia (VAP) caused by multidrug-resistant organisms. Ensuring effective antibiotic concentrations at the site of infection in the interstitial space fluid is crucial for clinical outcomes. Current assessment methods, such as epithelial lining fluid and tissue homogenates, have limitations in providing longitudinal pharmacokinetic data. MAIN BODY: Lung microdialysis, an invasive research technique predominantly used in animals, involves inserting probes into lung parenchyma to measure antibiotic concentrations in interstitial space fluid...

BACKGROUND: Prescribers have an increasing range of inhaled antimicrobial formulations to choose from when prescribing both eradication and chronic suppression regimens in cystic fibrosis (CF). This study aimed to investigate the decision-making process behind prescribing of inhaled antimicrobials for Pseudomonas aeruginosa infections. METHODS: A questionnaire was developed using Microsoft Forms and then forwarded to 57 Principal Investigators (PIs), at each of the CF centres within the European Cystic Fibrosis Society-Clinical Trials Network (ECFS-CTN)...

Specialists caring for people with bronchiectasis recommend specialised nebulisers for inhaled antibiotics, but are often limited by availability and cost of nebulisation devices https://bit.ly/40FvFdZ.

BACKGROUND: Burn inhalation injury (BII) is a major cause of burn-related mortality and morbidity. Despite published practice guidelines, no consensus exists for the best strategies regarding diagnosis and management of BII. A modified DELPHI study using the RAND/UCLA (University of California, Los Angeles) Appropriateness Method (RAM) systematically analysed the opinions of an expert panel. Expert opinion was combined with available evidence to determine what constitutes appropriate and inappropriate judgement in the diagnosis and management of BII...

BACKGROUND: Nebuliser systems are used to deliver medications to the lungs, to control the symptoms and the progression of lung disease in people with cystic fibrosis (CF). There are many different nebulised-medications prescribed for people with CF and there are many different types of nebuliser systems. Some of these nebulised medications are licenced for, and can be taken via only one type of nebuliser system; some are licensed for, and can be taken via more than one type of nebuliser system...

OBJECTIVES: Phage-resistant bacteria often emerge rapidly when performing phage therapy. However, the relationship between the emergence of phage-resistant bacteria and improvement in clinical symptoms is still poorly understood. METHODS: An inpatient developed a pulmonary infection caused by multidrug-resistant Klebsiella pneumoniae. He received a first course of treatment with a single nebulised phage (ΦKp_GWPB35) targeted at his bacterial isolate of Kp7450...

Respiratory infections caused by Staphylococcus aureus and Pseudomonas aeruginosa are a major concern for cystic fibrosis (CF) patients due to increasing antibiotic resistance. Bacteriophages, which are viruses that selectively target and kill bacteria, are being studied as an alternative treatment for these infections. This systematic review evaluates the safety and effectiveness of bacteriophages for the treatment of CF-related infections caused by S. aureus and/or P. aeruginosa. We conducted a search for original, published articles in the English language up to March 2023...

BACKGROUND: Cystic fibrosis (CF) is a life-limiting genetic disorder predominantly affecting the lungs and pancreas. Airway clearance techniques (ACTs) and exercise therapy are key components of physiotherapy, which is considered integral in managing CF; however, low adherence is well-documented. Poor physiotherapy adherence may lead to repeated respiratory infections, reduced exercise tolerance, breathlessness, reduced quality of life, malaise and reduced life expectancy, as well as increased use of pharmacology, healthcare access and hospital admission...

INTRODUCTION: People with cystic fibrosis (CF) are often on multiple long-term treatments, including mucoactive nebulisers. In the UK, the most common mucoactive nebuliser is dornase alfa (DNase). A common therapeutic approach for people already on DNase is to add hypertonic saline (HS). The effects of DNase and HS used alone have been studied in randomised trials, but their effects in combination have not. This study investigates whether, for people already prescribed DNase, adding HS has additional benefit for lung function or use of intravenous antibiotics...

BACKGROUND: In people with cystic fibrosis (CF), regular nebulisation of 6% or 7% saline improves lung function; however, these concentrations are not always tolerable. Clinically, some CF patients report using lower concentrations of saline to improve tolerability, yet the effects of lower concentrations are unknown. This study therefore aimed to evaluate the relative effectiveness and tolerability of 0.9% versus 3% versus 6% saline nebulised twice daily with an eFlow rapid nebuliser...

BACKGROUND: Hypertonic saline enhances mucociliary clearance and may lessen the destructive inflammatory process in the airways. This is an update of a previously published review. OBJECTIVES: To investigate efficacy and tolerability of nebulised hypertonic saline treatment in people with cystic fibrosis (CF) compared to placebo or other treatments that enhance mucociliary clearance. SEARCH METHODS: We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Cystic Fibrosis Trials Register, comprising references identified from comprehensive electronic database searches, handsearches of relevant journals and abstract books of conference proceedings...

BACKGROUND: Regular daily nebulised antibiotics are widely used in managing bronchiectasis. This patient population typically has severe bronchiectasis requiring multiple other medications. Given that little is known about patients' views and preferences for such therapies, this was the focus of our study. METHODS: To explore patient lived-experience using nebulised antibiotics, focus groups and semi-structured interviews were conducted with patients and carers; these were audio-recorded and transcribed to enable thematic analysis...

BACKGROUND: Respiratory tract infections with Pseudomonas aeruginosa occur in most people with cystic fibrosis (CF). Established chronic P aeruginosa infection is virtually impossible to eradicate and is associated with increased mortality and morbidity. Early infection may be easier to eradicate. This is an updated review. OBJECTIVES: Does giving antibiotics for P aeruginosa infection in people with CF at the time of new isolation improve clinical outcomes (e.g...

INTRODUCTION: Cystic fibrosis (CF) is a multisystem condition that is complicated by recurrent pulmonary infections requiring aggressive antibiotic treatment. This predisposes the patient to complications such as sensorineural hearing loss, renal impairment, hypersensitivity and the development of antibiotic resistance. Pseudomonas aeruginosa is one of the more common organisms which cause recurrent infections and result in greater morbidity and mortality in people living with CF. Bacteriophages have been identified as a potential alternative or adjunct to antibiotics...

Respiratory tract infections (RTIs) are reported to be the leading cause of death worldwide. Delivery of liposomal antibiotic nano-systems via the inhalation route has drawn significant interest in RTIs treatment as it can directly target the site of infection and reduces the risk of systemic exposure and side effects. Moreover, this formulation system can improve pharmacokinetics and biodistribution and enhance the activity against intracellular pathogens. Microfluidics is an innovative manufacturing technology that can produce nanomedicines in a homogenous and scalable way...

BACKGROUND: Improved understanding and treatment of cystic fibrosis (CF) has led to longer life expectancy, which is accompanied by an increasingly complex regimen of treatments. Suboptimal adherence to the treatment plan, in the context of respiratory disease, has been found to be associated with poorer health outcomes. With digital technology being more accessible, it can be used to monitor adherence to inhaled therapies via chipped nebulisers, mobile phone apps and web-based platforms...

The diagnosis of non-tuberculous mycobacteria (NTM) is a particular challenge in people with cystic fibrosis. Current standard diagnostic approaches rely on serial sputum culture, which is resource demanding, dependent on patient expectoration and may be compromised by excessive decontamination, conventional bacterial overgrowth and masking by concomitant oral and nebulised antibiotics. An alternative rapid, reliable and inexpensive diagnostic method is therefore urgently needed. Serum of patients with Mycobacterium abscessus infection and chronic suppurative lung disease without NTM infection was tested against an array of novel synthetic mycolic acids, identical or similar to natural components of mycobacterial cell walls, and glycopeptidolipid (GPL)-core antigen, which has previously been investigated in Mycobacterium avium pulmonary infection...

Children with chronic wet cough and without cystic fibrosis (non-CF) may suffer from chronic suppurative lung disease (CSLD) or bronchiectasis. Pseudomonas aeruginosa (Pa) can be one of the offending microbes in these children. The present study aimed to describe the clinical course of children with the above two conditions who were infected with Pa. Data of 54 children with CSLD/bronchiectasis who were diagnosed and attended in our department were retrospectively analysed through a Cox proportional hazard model, with age, presence of bronchiectasis, use of inhaled colistin, azithromycin, inhaled hypertonic saline as the covariates...
