About this study

Title: The acute effect of narghile smoking on endothelial Function, and exhaled breath condensate (EBC) and pulmonary function tests in healthy volunteers.

Objectives: To evaluate the acute effect of one cession of narghile smoking on endothelial Function, airway inflammation as assessed by exhaled breath condensate (EBC) in healthy volunteers.

Design: Prospective study evaluating these parameters before and after 30 minutes of Narghile smoking. The changes in inflammatory parameters pre and post smoking will be evaluated blindly.

Sample size: 50 participants Participant selection: Adults subjects who smoke Narghile . Intervention: Each subject will undergo evaluation including a respiratory questionnaire, endothelial Function , pulmonary function tests , exhaled breath condensate (EBC) and carboxy- hemoglobin levels . All measurements will be evaluated before and after one cession of 30 minutes narghile smoking.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. PRE - Endothelial Function as assessed by EndoPAT2000

    as assessed by EndoPAT2000. a pulse-oxymeter that asseses the endothelial function

    Measured: baseline (before smoking narghile)

  2. POST - Endothelial Function as assessed by EndoPAT2000

    as assessed by EndoPAT2000. a pulse-oxymeter that asseses the endothelial function

    Measured: after 30 minutes of smoking narghile

Secondary outcomes (8)
  1. carboxy- hemoglobin

    Blood Test

    Measured: before and immediatly after 30 min of smoking

  2. heart rate

    Heart Beats count

    Measured: before and immediatly after 30 min of smoking

  3. Visual Analog Score 1-10 (1=bad 10=good)

    Questionnaire

    Measured: before and immediatly after 30 min of smoking

  4. Respiratory Rate

    Measured: before and immediatly after 30 min of smoking

  5. Spirometry

    Koko spirometry system

    Measured: before and immediatly after 30 min of smoking

  6. Eosinophils Count

    Blood Test

    Measured: before and immediatly after 30 min of smoking

  7. Blood Pressure

    Regular Blood Pressure assesment

    Measured: before and immediatly after 30 min of smoking

  8. Exhaled Breath Condensate

    R-tubes test

    Measured: before and immediatly after 30 min of smoking

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

PRE - Endothelial Function as assessed by EndoPAT2000 (time frame: baseline (before smoking narghile)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01237548, which also lists 1 linked publication.
