Brief Summary:
The purpose of this study is to determine biomarkers of exposure to Harmful and Potentially Harmful Constituents (HPHCs) in Cigarette Smoke and cardiovascular-related biomarkers in smokers and non smokers.

Condition or disease
Smoking Healthy

Detailed Description:

Since Japanese mortality associated with cardiovascular disease (CVD) is lower than that in the USA although Japan is one of the top four tobacco consuming countries, this study aims to determine biomarkers of both level of exposure and CVD-related biological effects in Japanese smokers compared to non-smokers.

Biomarkers of Exposure (BoExp) include 2-naphthylamine (2-NA), 4-aminobiphenyl (4-ABP), 4-(methylnitrosaminoi)-1-(3-pyridil)-1-butanone (NNK), carbon monoxide (CO), nicotine, pyrene and 0-toluidine (o-TOL). CVD-related biomarkers include white blood cell (WBC) count, high sensitivity C-reactive protein (hs-CRP) and homocysteine in plasma; complemented with urinary 8-epi-prostaglandin F2α (8-epi-PGF2α), plasma malondialdehyde (MDA), urinary 11-DTXB2, plasma fibrinogen, high-density lipoprotein-cholesterol, triglycerides, sICAM-1, sVCAM-1 and von Willebrand Factor.

Outcome Measures

Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. The level of biomarkers of Exposure (BoExp) to HPHCs - present in cigarette smoke - in Asian smokers compared to non smokers [ Time Frame: At Visit 2 (up to14 days after Visit 1) ]
    To measure the level of smoking, at baseline the Fagerstrom nicotine dependence test and urinary cotinine are measured. For measurement of biomarkers of exposure, blood and 24 hour urine sampling are performed at V2.

  2. The level of CVD-related biomarkers in Asian smokers compared to non smokers [ Time Frame: At Visit 2 (up to14 days after Visit 1) ]
