Kidney Function in People With Cystic Fibrosis

This study aims to understand why people with cystic fibrosis (CF) develop kidney disease. Researchers will look at markers in your blood and urine that could help predict who is at risk or find kidney damage early. They will compare these markers over time in people with CF, especially during lung flare-ups, and with people who don't have CF. The goal is to better understand how CF and its treatments affect kidneys, and to find new ways to prevent, diagnose, and treat kidney problems related to CF. You can join if you have CF and are over 7 years old (for inpatients) or over 30 years old (for outpatients). The study will be successful if it finds links between kidney function changes and these markers, and if it helps understand why some people with CF are hospitalized more often.

Study design
This is an observational study involving 260 participants, including outpatients with CF, inpatients with CF, and healthy individuals.
What's involved
You would provide blood and urine samples at enrollment and every 3 months for 24 months. If hospitalized, samples would be taken on admission, every 48 hours, and after discharge at routine CF care visits.
Compensation
Not stated in the trial record.
Follow-up
Participants will be followed for 24 months after enrollment or discharge.
