Coorti e interventi
Gruppo / CoorteGruppo / Coorte |
|---|
|
Acute Pulmonary Exacerbation (APE)
Those subjects presenting with APE will be treated with at least two pathogen specific I.V. antibiotics, as dictated by their treating physician and compliant with standard guidelines for care of an APE.
|
|
Baseline Health
Those subjects presenting at baseline health will be identified by their treating physician as such and will not be starting on any treatments for APE.

|
|
Difference in CD4+ T cell TLR2 expression
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
The primary outcome measure is the difference in expression of CD4+ T cell TLR2 as measured by flow cytometry from circulating blood between the two groups (APE and baseline).

Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
|
Difference in GILT expression
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health

|
Correlation of primary outcome measurements with C-Reactive Protein
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health

A secondary outcome measure is the correlation of the differences in expression of neutrophil CD64, CD4+ T cell TLR2, and GILT with differences in C-Reactive Protein (CRP)
|
Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
|
Correlation of primary outcome measurements with total white blood cell counts
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
A secondary outcome measure is the correlation of the differences in expression of neutrophil CD64, CD4+ T cell TLR2, and GILT with differences in total white blood cell counts (WBC).
|
Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
|
Correlation of primary outcome measurements with sputum inflammatory markers
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
A secondary outcome measure is the correlation of the differences in expression of neutrophil CD64, CD4+ T cell TLR2, and GILT with differences in sputum inflammatory markers as measured by sputum neutrophil counts and neutrophil elastase expression.
|
Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
|
Correlation of primary outcome measurements with phagocytosis
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
A secondary outcome measure is the correlation of the differences in expression of neutrophil CD64, CD4+ T cell TLR2, and GILT with differences in the percentage of phagocytosis by isolated neutrophils.
|
Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
|
Correlation of primary outcome measurements with quality of life questionnaire score
Lasso di tempo: Within 24 hours of initiation of IV antibiotic treatment for CF pulmonary exacerbation or at Baseline health
|
A secondary outcome measure is the correlation of the differences in expression of neutrophil CD64, CD4+ T cell TLR2, and GILT with differences in patient reported health related quality of life scores as measured by the Cystic Fibrosis Questionnaire-Revised (CFQ-R).
