Study Details

Brief summary:

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.

Interventions and Outcome Measures

Arms

Outpatient CF Cohort

Not hospitalized CF group: Diagnosis of CF, age >30 y, with ongoing care at one of the 3 CF Centers (Dartmouth, UAB, UVA).

Inpatient CF Cohort

Hospitalized CF cohort: Diagnosis of CF, age >7 y, being admitted for intravenous antibiotic treatment of pulmonary exacerbation.

Healthy Controls

Healthy Volunteers without CF

Primary outcome measure

  • 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. [ Time Frame: Enrollment and every 3 months for 24 months ]
  • Correlation between recurrent hospitalizations and urinary kidney injury signature. [ Time Frame: 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 [ Time Frame: 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. ]
