Urokinase Like Plasminogen Activator Levels in Patients Undergoing Bronchoscopy

This study has been completed.

Some of the risk factors for bleeding following bronchoscopy is having a malignancy or an immunocompromised state. The etiology of this remains uncertain. The investigators suspect that individuals with malignancy have abnormalities involving certain factors that influence the coagulation pathway.

The investigators plan to measure these factors prior to and after bronchoscopy.


Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Utility of Serum and Bronchoalveolar Fluid Urokinase Like Plasminogen Activator Levels in Defining Patients at Higher Risk of Hemoptysis.

  • Volume of blood loss during the procedure [ Time Frame: 1 day ]

Enrollment: 10
Study Start Date: June 2009
Study Completion Date: October 2011
Primary Completion Date: June 2010 (Final data collection date for primary outcome measure)
Lung cancer
Comparison between individuals with and without pulmonary malignancy

Detailed Description:
This is a prospective observational study looking at some coagulation factors in individuals with lung cancer. We are looking at BAL and plasma. We would like to see if there is a difference in the levels and if this is the reason behind the higher incidence of hemoptysis in patients with lung cancer.

Ages Eligible for Study:   18 Years to 80 Years   (Adult, Senior)

Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
Patients from the VAMC in Oklahoma city

Inclusion Criteria:
