Filter by:This trial aims to analyze whether the resistive inspiratory manoeuvre (RIM) performed previously to autogenic drainage (AD) technique improves the effectiveness in terms of mucus clearance during a typical bronchial drainage session in adults, stable CF patients.
The purpose of this study is the psychometric validation of a self-administered dyspnea questionnaire, usable in clinical practice in order to assess dyspnea and its impact on patients with chronic respiratory diseases.
This Phase 1 study in F508del-CFTR homozygous CF patients is being conducted to assess the pharmacokinetics and absorption dynamics of N91115 compared with healthy subjects in order to identify an initial starting dose for Phase 2 trials.
With better medical care, patients with cystic fibrosis (CF), a life-threatening disease, are enjoying longer lives. As the CF life expectancy increases, conditions such as CF-related diabetes (CFRD) become more prevalent. Nutrition plays a major role in maintaining optimal health in cystic fibrosis (CF). This project is designed to investigate nutrition-related factors, such as diet and body composition, on outcomes in patients with CF. The data generated from this study will be used to inform future nutrition intervention studies in adults with CF and CFRD.
The objective of this study is to determine if tobramycin inhalation powder (TIP) can reduce the amount of Burkholderia Cepacia Complex (BCC) species - type of bacteria, in the sputum of cystic fibrosis patient.
The morbidity and mortality associated with Cystic Fibrosis (CF) are the result of chronic suppurative lung disease. The aggressive use of antibiotics is one of the mainstays of treatment in CF, however, the problems of multiple drug resistance and adverse reactions are major clinical issues. Cysteamine is a licensed drug used in the treatment of cystinosis. In vitro work suggests that cysteamine has properties of potential benefit in CF. Cysteamine is a potent mucolytic, it disrupts biofilms, it is antimicrobial, and synergises with other antibiotic agents. CF is characterised by malabsorption and it is not known whether cysteamine is absorbed in CF, furthermore it is not known if cysteamine enters the bronchial secretions. It is not possible to assume that the pharmacokinetics of cysteamine in patients with CF are the same as those reported for cystinosis. Objectives: to characterise the pharmacokinetic profile of cysteamine in people with CF, to ascertain whether cysteamine enters the bronchial secretions and the tolerability of cysteamine by patients with CF. Method: a single centre, single group open label investigation of the tolerability and pharmacokinetics of oral cysteamine (Cystagon) when administered to patients with Cystic Fibrosis at the dose licensed for use in cystinosis. Setting: adult CF clinic, Aberdeen Royal Infirmary. Target population: 12 patients aged ≥18years with CF associated lung disease who are clinically stable. Intervention: Oral cysteamine (Cystagon) will be increased from 450mg od to 450mg qds over three weeks, they will remain on 450mg qds for two weeks. Assessment: face to face health outcome assessments will be carried out for all participants at recruitment/baseline, 1, 2, 3, and 5 and 6 weeks. Serial blood cysteamine levels will be measured in the first 24 hours after the first dose. Sputum cysteamine will be quantified after two weeks of full dose cysteamine 450mg qds. Disease specific health status (CFQ-R) will be assessed at baseline and after two weeks of full dose. At each assessment, lung function (FEV1, FVC), adverse reactions and serious adverse events will be ascertained. Blood samples will be taken for measurement of haematological and biochemical parameters. Sputum samples at each assessment will be analysed for microbial load and spinnbarkeit.
Current guidelines on the diagnoses and management of cystic fibrosis (CF) related diabetes recommend treatment for diabetes based on diagnostic criteria derived from adults with type 2 diabetes. Increasing evidence supports treating early glucose abnormalities in cystic fibrosis patients to target CF specific outcomes, including lung function and nutrition (BMI-Body Mass Index). However, the criteria and timing of when to start insulin therapy in the 'prediabetic' state are unclear. A more accurate characterization of blood sugar variability in youth with and without CF will help the investigators better interpret continuous glucose monitor (CGM) findings in patients with CF prediabetes and diabetes and more accurately identify those individuals at greatest risk for disease progression.
Exploratory comparative evaluation of exhaled breath composition in cystic fibrosis patients with age and gender-matched healthy adults in order to identify a disease-specific exhaled breath pattern as well as to gain insight into pathophysiological and microbial contributions to exhaled breath composition.
Anyone who practices clinical medicine will understand that socially disadvantaged children will have worse health outcomes, no matter what the underlying condition might be. There is limited prospective data on the effects of social deprivation on children in BC and there is none concerning the effects of social deprivation on children with chronic diseases. In order to generate relevant data for those who manage children with chronic diseases in BC, the investigators wish to perform an observational study of the relationship between questionnaire-derived social variables and measured outcomes in children with cystic fibrosis, type 1 diabetes, and chronic kidney disease. Our working hypothesis is that there is an association between social determinants of health (income, education, race) and health outcomes in children with cystic fibrosis, type 1 diabetes and chronic renal failure, that is independent of access to health care (assessed by distance to nearest specialty clinic and number of clinic visits in the last year).
Cystic fibrosis-related diabetes (CFRD) occurs in almost 20% of teens and 50% of adults. The investigators' long term goal is to determine the cause of CFRD in order to translate this knowledge into therapies aimed at preventing CFRD. Since CFRD and type 2 diabetes share several clinical features and since oxidative stress is a key factor in the development of type 2 diabetes, the investigators explored the role of oxidative stress in CFRD. The investigators discovered a unique CF biochemical signature that they believe could be implicated in the development of CFRD. The investigators found that glucose ingestion in CF teens and young adults causes an acute and profound systemic redox imbalance to the oxidizing state. The degree of redox imbalance was quite severe and would be expected to damage the insulin producing cells as these cells are particularly vulnerable to oxidative stress. Thus, these findings could prove to be a critical factor in the pathogenesis of CFRD. This proposal will test the hypothesis that glucose-induced redox imbalance is an intrinsic, metabolic defect in CF. In addition, because CF people are required to consume a high calorie diet to maintain their weight, the investigators also hypothesize that certain high caloric foods will recapitulate the redox imbalance induced by ingesting glucose and thus hasten the development of CFRD. Specifically, the investigators aim to: - Determine whether young children with CF have glucose-induced redox imbalance - Determine whether eating a meal with a high glycemic index induces acute redox imbalance - Determine whether commonly consumed beverages containing simple sugars (i.e., soda or fruit juice) induce acute redox imbalance
