OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks of the observation period.

Population: 1 patient in Divaza group had no laboratory data.

Based on laboratory evaluation. Change in mean value of lipoprotein ability for oxidation after 12-week therapy versus baseline. For plasma, draw blood into an EDTA tube and gently invert the tube 8 to 10 times to mix the anticoagulant. Centrifuge the tube, remove the stopper and draw off approximately 2/3 of the upper plasma layer into a labeled transfer tube using a transfer pipet bulb. Plasma must be separated from cells within 45 minutes of venipuncture. Measurement of oxidized LDL (oxLDL) has been incorporated into clinical practice in the diagnosis and treatment of lipid disorders (such as diabetes mellitus), atherosclerosis, and various liver and renal diseases, especially as it pertains to the evaluation of oxidative stress. Oxidized LDL-particles are considered to be an important driving factor in the pathophysiology of atherosclerosis and oxLDL measurement has been used to test the efficacy of CVD drugs (eg, statins) to reduce oxidative stress.

OTHER_PRE_SPECIFIED outcome

Timeframe: 12 weeks of the observation period.

Based on laboratory evaluation. Change in the mean concentration of nitrites and nitrates in serum after 12-week therapy versus baseline. Griess Reaction assay. In the Griess reaction, first reported by Johann Peter Griess in 1879 as a method of analysis of nitrite (NO2-), nitrite reacts under acidic conditions with sulfanilic acid (HO3SC6H4NH2) to form a diazonium cation (HO3SC6H4-Ntriple bondN+) which subsequently couples to the aromatic amine 1-naphthylamine (C10H7NH2) to produce a red-violet coloured (λmax ≈ 540 nm), water-soluble azo dye (HO3SC6H4-Ndouble bondN-C10H6NH2).
