Filter by:Although cystic fibrosis (CF) is the most common, life-threatening autosomal recessive genetic disorder of the white population, there are often delays in diagnosis and hence start of treatment. Advances of the past two decades have made CF screening feasible using routinely collected neonatal blood specimens and measuring an enzyme level followed by CF mutation DNA analysis. Our overall goal of the study is to see if early diagnosis of CF through neonatal screening will be medically beneficial without major risks. ''Medically beneficial'' refers to better nutrition and/or pulmonary status, whereas '' risks'' include laboratory errors, miscommunication or misunderstanding, and adverse psychosocial consequences. Specific aims include assessment of the benefits, risks, costs, quality of life, and cognitive function associated with CF neonatal screening and a better understanding of the epidemiology of CF. A comprehensive, randomized clinical trial emphasizing early diagnosis as the key variable has been underway since 1985. Nutritional status has been assessed using height and weight measurements and biochemical methods. The results have demonstrated significant benefits in the screened (early diagnosis) group. We are now focusing on the effect of early diagnosis of CF on pulmonary outcome. Pulmonary status is measured using chest radiographs, chest scans using high resolution computerized tomography, and pulmonary function tests. Other factors that we are looking at include risk factors for the acquisition of respiratory pathogens such as Pseudomonas aeruginosa, quality of life and cognitive function of children with CF who underwent early versus delayed diagnosis, as well as the cost effectiveness of screening and the costs of diagnosis and treatment of CF throughout childhood. If the questions underlying this study are answered favorably, it is likely that neonatal screening using a combination of enzyme level (immunoreactive trypsinogen) and DNA test will become the routine method for identifying new cases of CF not only in the State of Wisconsin, but throughout the country.
OBJECTIVES: I. Determine the amount of hepatic glucose production derived from gluconeogenesis and glycogenolysis in the post-absorptive state in patients with cystic fibrosis. II. Determine de novo lipogenesis in relationship to resting energy expenditure in this patient population.
People with cystic fibrosis (CF) now frequently live into adulthood and with this extended life expectancy has come new clinical problems. Poor bone health, including osteoporosis and bone fractures, is one of these increasingly important conditions. Preventing the negative outcomes of poor bone health in later life is primarily related to ensuring optimal growth (weight and height) and obtaining maximal amount of bone mass during growth and development. This study will identify factors that influence bone health in a sample of children, adolescents and young adults as measured by dual energy x-ray absorptiometry and new bone densitometry methods (peripheral quantitative computerized tomography [p-QCT] and bone sonometer). We will also identify factors which influence changes in bone status over a 12-month follow-up period in a subsample of people with CF.
This study's primary goals are to test the safety and effectiveness of Tobramycin for Inhalation (TOBIr) in cystic fibrosis (CF) patients who are between 6 months and 6 years of age. This drug is an antibiotic that is inhaled into the lungs by the patient. It has already been studied and approved by the FDA for treatment of CF patients 6 years and older. Lung fluid will be examined for bacteria before and after the 28-day treatment. The amount of bacteria before and after treatment will be compared. This will indicate whether the antibiotic was effective in killing bacteria in the lungs. Once treatment begins, patients will be monitored every 2 weeks throughout the study (5 exams in 56 days). Half of the patients will receive TOBIr, half will receive a placebo (a substance that looks like TOBIr but contains no medication).
The current study examines the efficacy of two treatments to help children with cystic fibrosis (CF) meet their dietary calorie requirements of 120% to 150% of the recommended daily allowance of energy and the effect of these treatments on weight gain and maintenance. One treatment provides children with CF and their parents nutrition education about the best foods for meeting their dietary needs. The second treatment gives children with CF and their families similar nutritional information plus behavioral parenting methods for motivating children to eat the recommended foods. Children with CF and their families are seen weekly for 7 treatment sessions across 9 weeks for the active phase of treatment. Families are then followed for 2 years after treatment in order to better understand how long the treatments are effective and to determine the health benefits of better nutrition status and weight gain.
OBJECTIVES: I. Compare the efficacy of enteric coated pancrelipase with bicarbonate (PANCRECARB) capsules versus the patient's usual enteric coated pancreatic enzyme without bicarbonate in decreasing fecal fat and nitrogen losses in patients with cystic fibrosis.
Cystic Fibrosis (CF) is the most common lethal genetic disorder in America. Previous studies by our group and others have shown that human recombinant growth hormone (GH) improves height velocity, weight velocity, lean body mass (LBM) and pulmonary function. These positive results have prompted us to ask further questions regarding GH use in CF including: a) Do patients with better baseline body weight and pulmonary function derive more benefit from treatment than those with worse weight and pulmonary function?, b) Does GH use improve the patient's quality of life?, c) Once GH is discontinued, are the positive effects sustained? We hypothesize that GH treatment in CF patients will improve their clinical status and their quality of life. We further hypothesize that these effects will be present regardless of baseline body weight or pulmonary function, and that positive outcome will be sustained for at least one year after GH treatment is discontinued. To test our hypothesis, we will recruit 40 prepubertal children from five CF centers across the United States (8 per center). Patients will be randomly assigned to receive treatment with GH (0.3mg/kg/wk) during either the first or the second year. All subjects will be seen every three months. We will evaluate the following parameters every three months: 1) height, height velocity and Z-score, 2) body weight and weight velocity. Every six months we will measure: 1) lean body mass utilizing DEXA, 2) pulmonary function, including measurement of respiratory muscle strength (peak inspiratory and peak expiratory pressure), 3) quality of life (QOL), quantitated from QOL forms specific for CF ("The Cystic Fibrosis Questionnaire"). After one year of study, subjects will "cross-over" to the other treatment arm. This 24 month study will allow us to statistically compare outcome measures in 20 treated and 20 nontreated subjects from multiple centers, and will allow us to assess sustained effect in the 20 subjects who receive GH during the first year, by comparing their results to results obtained during the year post treatment.
OBJECTIVES: I. Determine the safety and efficacy of tobramycin in patients with cystic fibrosis who are chronically colonized with Pseudomonas aeruginosa. II. Determine whether this treatment produces tobramycin-resistant bacteria at a frequency different from the placebo group and whether the emergence of resistance is associated with a lack of clinical response.
OBJECTIVES: Evaluate the efficacy and safety of lipid-mediated transfer of the cystic fibrosis transmembrane conductance regulator gene to nasal epithelium in patients with cystic fibrosis.
OBJECTIVES: I. Assess the safety and efficacy of gene transfer into the nasal epithelium using Ad5-CB-CFTR, an E1-deleted adenovirus vector containing the cystic fibrosis transmembrane conductance regulator gene, in patients with cystic fibrosis (CF). II. Determine whether ion transport abnormalities in CF airway cells can be corrected.
