GliSODin, a vegetal sod with gliadin, as preventative agent vs. atherosclerosis, as confirmed with carotid ultrasound-B imaging.

Prevention of cardiovascular disease should target high-risk subjects based on genetic/familial factors, blood chemistry, blood pressure, body mass index (BMI), and a history of/or current cigarette smoking. We selected active adults (n=76) aged 30-60 and investigated these risk factors, in order to recommend preventive measures. Another interesting variable is the preclinical status or atheroma of the arterial (carotid) wall or lumen. We also investigated the presence of oxidative stress in, and the anti-oxidant status of these subjects. We studied the anti-oxidative efficacy of superoxide dismutase (SOD) and variations of malondialdehyde (MDA). Supplementation with GliSODin, a vegetal SOD associated with gliadin, was effective in controlling the thickness of the carotid artery intima and media layers as measured by ultrasonography-B. We could demonstrate the preventive efficacy of GliSODin at a preclinical stage in subjects with risk factors of cardiovascular disease.

Objectifying exercise ischemia in peripheral vascular disease: a study in 120 patients.

This study presents the results of transcutaneous oxygen pressure (TcPO2) monitoring during a treadmill test walk performed in the early stages of peripheral obliterative vascular disease. The study population consisted of a first group of 50 known arteriopathic patients presenting, on questioning, with intermittent claudication; a second group of 50 known arteriopathic patients void of any symptoms of intermittent claudication; and a third group, which was a control cohort of 20 nonarteriopathic, nonclaudicating patients. Though resting TcPO2 cannot be used to aid the clinical diagnosis of exercise ischemia it may be useful in revealing asymptomatic chronic resting ischemia (9% of cases in this series). On the other hand, a posteffort (recovery phase) fall in TcPO2 had a predictive positive diagnostic accuracy for ischemia on exercise in 99% of the cases reported here versus 87% for clinical appraisal. In the light of these results, TcPO2 measurements coupled to a treadmill test walk perfectly ascertain exercise ischemia in arteriopathic patients, whether asymptomatic or not, and avoid the false-positive results obtained by clinical evaluation.
