Brief Summary
The goal of this study is to identify chemical compounds in the blood and sputum (i.e., biomarkers) that are associated with objective measurements of health status in patients with cystic fibrosis (CF). This study builds upon observations that blood levels of hepcidin-25, a protein that regulates how the body uses and stores iron, vary during CF pulmonary exacerbation (CFPE).

Outcome Measures
Primary Outcomes (1)
Change in Serum Hepcidin-25 Concentration After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
The primary endpoint of this study is the characterization of 3 groups (i.e., "low," "intermediate," and "high") of serum hepcidin-25 responders to CFPE treatment. Response will be defined as the ratio of post- to pre-treatment serum hepcidin-25 concentration for each subject.
Duration of hospitalization, an expected average of 12 days
Secondary Outcomes (11)
Change in Percent-Predicted Forced Expiratory Volume in One Second (FEV1%) After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in Body Mass Index (BMI) After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in CFRSD-CRISS Score After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in Serum Iron After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in Serum Interleukin-6 (IL-6) Concentration After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
- +6 more secondary outcomes
Other Outcomes (3)
Change in Sputum SDI After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in Sputum Pseudomonas aeruginosa Gene Expression After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Change in Peripheral Blood Mononuclear Cell (PBMC) Gene Expression After Hospitalization for CF Pulmonary Exacerbation (CFPE) Treatment
Duration of hospitalization, an expected average of 12 days
Study Arms (1)
Adults - CFPE Treatment
Other: CF Pulmonary Exacerbation (CFPE) Treatment
Interventions
Hospitalization for comprehensive treatment of CF pulmonary exacerbation, including intravenous (IV) antibiotics, nutritional assessment and support, airway clearance of mucus, use of inhaled mucolytic agents and bronchodilators, glycemic control with insulin, and psychosocial support.
Eligibility Criteria
Patients greater than
You may qualify if:
- Diagnosis of CF confirmed by history of positive chloride sweat test and/or CFTR mutation analysis;
- History of consistent sputum production on most occasions;
- FEV1% greater than or equal to 75% of best measurement in previous 6 months;
- or more hospitalizations for CFPE treatment with intravenous antibiotics within the previous year;
- Absence of CFPE (i.e., Akron Pulmonary Exacerbation Score \<5);
- Not admitted to hospital within the previous 3 weeks;
- Body weight greater than or equal to 75% of best measurement in previous 6 months;
- Provision of signed informed-consent to study protocol;
- \<Age\>65
You may not qualify if:
- Women who are pregnant or lactating;
- Recent and/or persistent visible blood in sputum (hemoptysis);
- Rescue use of oral antibiotics within the previous 3 weeks, defined as antibiotic use for health deterioration rather than chronic suppression
