Brief Summary

Cystic fibrosis (CF) is a chronic multiorgan disorder caused by mutations in the CFTR (cystic fibrosis transmembrane conductance regulator) gene. Chronic airway infection by bacterial pathogens accounts for the progressive, suppurative pulmonary disease that leads to significant morbidity and mortality in patients with CF. Neutrophil recruitment to the lungs accounts the most important contributor to pulmonary destruction. However, there is evidence that platelets may also have an important role in the pathogenesis of inflammation. To our knowledge, there is few information in platelet levels in patients with cystic fibrosis during pulmonary exacerbation, chronic airway colonization and when stable.

Outcome Measures

Primary Outcomes (1)

  • Platelet levels and mean platelet volume in acute pulmonary infection in patients with cystic fibrosis

    Elevated platelet level count (x103/uL) and increased mean platelet volume (fl) during acute pulmonary exacerbation in cystic fibrosis patients

    2 weeks

Study Arms (6)

Group 1. Total cystic fibrosis patients with pulmonary exacerbation

Platelet count (PC) and mean platelet volume (MPV) during pulmonary exacerbation.

Other: platelet count and mean platelet volume are obtained from whole blood count

Group 2. Total cystic fibrosis patients with no pulmonary exacerbation

PC and MPV during no pulmonary exacerbation

Other: platelet count and mean platelet volume are obtained from whole blood count

Group 3. Cystic fibrosis patients with chronic colonization in acute pulmonary exacerbation

PC and MPV during chronic colonization in acute pulmonary exacerbation

Other: platelet count and mean platelet volume are obtained from whole blood count

Group 4. Cystic fibrosis patients with chronic colonization without pulmonary exacerbation

PC and MPV during chronic colonization without pulmonary exacerbation

Other: platelet count and mean platelet volume are obtained from whole blood count

Group 5. Cystic fibrosis patients with chronic colonization without pulmonary exacerbation

PC and MPV during chronic colonization without pulmonary exacerbation

Other: platelet count and mean platelet volume are obtained from whole blood count

Group 6. Cystic fibrosis patients with no chronic colonization without pulmonary exacerbation

PC and MPV during no chronic colonization without pulmonary exacerbation

Other: platelet count and mean platelet volume are obtained from whole blood count

Interventions

The records of cystic fibrosis patients will be retrospectively evaluated for acute pulmonary exacerbation, chronic airway colonization for bacteria, clinical stable status. PC and MPV will be obtained and matched in 6 groups (described above). Then, PC and MPV will be compared among the groups.

Group 1. Total cystic fibrosis patients with pulmonary exacerbationGroup 2. Total cystic fibrosis patients with no pulmonary exacerbationGroup 3. Cystic fibrosis patients with chronic colonization in acute pulmonary exacerbationGroup 4. Cystic fibrosis patients with chronic colonization without pulmonary exacerbationGroup 5. Cystic fibrosis patients with chronic colonization without pulmonary exacerbationGroup 6. Cystic fibrosis patients with no chronic colonization without pulmonary exacerbation
