The Role of Bacteria and Genetic Variations in Cystic Fibrosis
United States76 participantsStarted 2001-06-20
Plain-language summary
This study will examine 1) the role of hereditary factors in cystic fibrosis; i.e., the relationship of the disease to specific gene variations, and 2) the role of bacterial products involved in lung infections substances produced by bacteria may worsen the disease.
Patients with cystic fibrosis who are being followed by the Medical College of Wisconsin or the University of Wisconsin-Madison are eligible for this study. Participants will have blood tests, pulmonary function tests, a sputum culture, and buccal swabbing (cotton swabbing of the inside of the cheek to collect cells for DNA study). In addition, their medical records will be reviewed for a history of lung infections and the results of various tests, including pulmonary function studies, chest X-rays and bacterial cultures. Blood samples collected previously at the Medical College of Wisconsin or the University of Wisconsin-Madison will also be analyzed for antibodies to bacteria.
Although this is a one-time study, participants may be asked to return for repeated tests.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
* INCLUSION CRITERIA:
Patients with cystic fibrosis who have a defined mutation in CFTR (e.g., any of the known variants of the CFTR gene, such as the delta F508 allele) born in the state of Wisconsin since 1985 or otherwise followed by the cystic fibrosis centers at the Medical College of Wisconsin or University of Wisconsin-Madison.
Patients will have been tested or will be tested for the CFTR gene under another protocol (96-H-0100).
Patients may be colonized with P. aeruginosa or other organisms (e.g., Burkholderia cepacia).
The age range of NIH participants in this study is from 9 to 80 years old.
EXCLUSION CRITERIA:
There are no exclusion criteria.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
There is a relationship between the virulence characteristics of P.aeruginosa involved inpersistent infection of the lung and the genetic profile of CF patients.
