The purpose of this study is to find out what causes kidney disease in people with CF. The investigators will study biomarkers in the blood and urine that can either predict who is at risk or detect kidney damage early before it becomes permanent. The study will compare these markers in people with CF over time and during the treatment of lung flare-ups. It will also compare the blood and urine samples obtained from people without CF. The comparison aims to better understand the impact of cystic fibrosis and its treatment on the kidneys, as well as to develop improved methods for preventing, diagnosing, and treating kidney issues associated with CF.

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.

Examine whether trajectories of eGFR (calculated from serum creatinine and cystatin C) correlate with urinary kidney injury signatures detected in different urine fractions, or urinary neutrophil levels/activation.
Timeframe: Enrollment and every 3 months for 24 months
Correlation between recurrent hospitalizations and urinary kidney injury signature.
Timeframe: On admission before the initiation of intravenous antibiotic therapy, every 48 hrs during the hospitalization, after discharge at each subsequent routine CF care visit for 24 months.
Relationship between recurrent hospitalization and change in slope of eGFR
Timeframe: On admission before the initiation of intravenous antibiotic therapy, every 48 hrs during the hospitalization, after discharge at each subsequent routine CF care visit for 24 months.
