Characterization of Antibacterial Antibodies in Patients With Cystic Fibrosis
Pulmonary Cystic FibrosisNeutralizing AntibodiesMost of the cystic fibrosis (CF) patients are or have been pulmonary colonized with bacteria such as Pseudomonas aeruginosa or Staphylococcus aureus. Aim of this study is to detect virulence factor neutralizing antibodies in the sera of the study population followed by B cell repertoire analyses to design B cell-derived neutralizing monoclonal antibodies. The functionality of neutralizing antibodies rests on inhibition of virulence factors by binding of crucial epitopes rather than merely the induction of opsonization. Focusing on patients with bacterial colonization/chronic infections or a history of an acute infection in the past, will increase the likelihood for identification of serum with neutralizing activity as in vivo antigen contact is a prerequisite for antibody development and maturation. Since virulence factors are essential for infection, dissemination and tissue damage, inhibition of these factors by developed neutralizing antibodies might contribute to a favorable outcome of life-threatening infections.
Clinical and Genetic Profile of Pediatric Patients With Cystic Fibrosis in Sohag.
Cystic FibrosisCystic fibrosis (CF) is an autosomal recessive genetic disorder caused by mutations in the gene encoding CF transmembrane conductance regulator (CFTR), which is located at 7q31.2 and encodes 1480 amino acids. CFTR protein is responsible for regulating the transport of electrolytes and chloride across epithelial and mucus-producing cell membranes.
A Comprehensive Approach To Relief Of Digestive Symptoms In Cystic Fibrosis: CARDS-CF
Cystic FibrosisDigestive System Disease4 moreDevelopment of a new patient reported outcome measure (PROM) that will measure the daily burden of gastrointestinal symptoms over the previous 24 hour period for people with cystic fibrosis.
MR Imaging of Lung in the Follow-up Assessment of Cystic Fibrosis
Cystic FibrosisThe aim of the study is to assess the diagnostic sensitivity of MRI to detect changes in Helbich-Bhalla scoring over time in patients with cystic fibrosis
A Multi-Centered Study of the Long-Term Effect of Salmeterol and Albuterol in Cystic Fibrosis
Cystic FibrosisLong term use of bronchodilators in CF is beneficial to the improvement of pulmonary function and symptoms. This study is investigating the long-term benefit of administration of the drug Salmeterol, a bronchodilator. Salmeterol will be compared to albuterol or placebo. The medication will be inhaled twice a day for 6 months.
Observational Study Comparing Home to Office Spirometry
Cystic FibrosisThis is a prospective, longitudinal multicenter observational study comparing home to office spirometry and home to office weight and height measurements. The aim of the study is to estimate the accuracy and variability of home spirometric measurements over time, and to assess the feasibility and acceptability of home measurements.
Improving P. Aeruginosa Detection With Breath-based Diagnostics (IMPACT-Breath)
Cystic FibrosisThe study is a breath biomarker validation study. It is anticipated that 300 patients with cystic fibrosis (CF) from 5 clinical sites in the USA will be enrolled. The study is funded by the US NIH and the US Cystic Fibrosis Foundation. Enrollment commenced in May 2019. Sputum, induced sputum, and oropharyngeal swabs will be collected and evaluated at each clinic as part of standard clinical practice. Excess sputum will be sent to Children's Colorado Hospital for molecular analysis. No swabs will be sent anywhere (other than the clinic from which they originate). Breath samples will be taken from all study participants.
Bacterial Gene Profiling to Predict Antibiotic Resistance During Cystic Fibrosis Pulmonary Exacerbations...
Cystic FibrosisPulmonary exacerbations (PEx) are key events that lead to a decline in health status among CF patients, with many never recovering to baseline health. With the advancement of new CFTR modulators and other therapies increasing the lifespan of those living with CF, it will become increasingly important to have better strategies to manage PEx in order to have better outcomes following treatment. PEx treatment decisions will need to take into consideration the increasing frequency of antimicrobial resistance bacteria and the need to treat multiple types of bacteria at once. The purpose of this study is to analyze sputum samples from CF subjects at the time of PEx in order to identify markers of antimicrobial resistant bacteria and see how those relate to treatment responses. CF patients will be recruited from patients followed by the Adult CF Program at National Jewish Health. Within 48 hours of admission to the hospital for treatment of a PEx, subjects will be enrolled and sputum will be collected. The sputum will be processed and analyzed for the presence of antimicrobial resistant bacteria. These results will be compared to clinical data, such as spirometry and frequency of hospitalizations.
Alternate Measures of Glucose During OGTT Testing for CFRD
Cystic FibrosisCystic Fibrosis-related DiabetesAlthough early detection and treatment of cystic fibrosis-related diabetes (CFRD) can lead to significant clinical improvements and prolong life, rates of screening are poor likely due to the burdensome nature of oral glucose tolerance testing (OGTT). The investigators propose to assess the feasibility and accuracy of two screening tools, continuous glucose monitoring (CGM) and a home OGTT kit (GTT@home). If this pilot study reveals acceptable accuracy of either device, this study will allow for future studies exploring home-based OGTT screening.
