Scientific titleRisk/benefit ratio of polyphenols and ethanol contained in red wine: a randomised, crossover, controlled clinical trial of the scientific basis of the effects of moderate consumption of red wine on cardiovascular system
Study hypothesisThe benefit of the main components of red wine, namely ethanol and polyphenolic content is synergistic. No adverse events will be observed.

As of 23/05/2012, the target number of participants were updated from 125 to 73.
Ethics approval(s)Institutional Review Board of the Hospital Clinic of Barcelona approved
ConditionArteriosclerosis
InterventionCurrent interventions as of 23/05/2012
Intervention 1: 100 ml/day of gin
Intervention 2: 272 ml/day of red wine
Intervention 3: 272 ml/day of dealcoholised red wine

Initial wash-out period (15 days); first intervention - 28 days; second intervention - 28 days and third intervention - 28 days.

Previous interventions

Primary outcome measure1. Leukocyte adhesion molecule expression: lymphocyte and monocyte adhesion molecules on these cells will be marked with monoclonal antibodies (MAb) conjugated with fluorescein-isothiocyanate (FITC) and phycoerythrin (PE) by direct double immunofluorescence. The MAb of the adhesion molecules used will be: anti-CD11a (LFA-1), anti-CD40L, anti-CD11b (Mac-1) (Bender MedSystems Diagnostics, Vienna), anti-Sialyl Lewis (anti-CD15s) (Pharmingen, San Diego, CA), anti-CD49d (VLA-4) (Cytogmos). The monoclonal antibodies used to mark the T-lymphocytes will be anti-CD2 and monocytes, anti-CD14 (Caltag Laboratories, Burlingame, CA).
2. Soluble adhesion molecules: the following serum soluble adhesion molecules will be determined by enzyme-linked immunosorbent assay (ELISA) kits: soluble intercellular adhesion molecule-1 (sICAM-1), soluble vascular adhesion molecule 1 (sVCAM-1), sE-selectin, and sP-selectin, as well as soluble monocyte chemotactic protein-1 (sMCP-1), tumour necrotising factor-alpha (TNF-a), and interleukin B (IL-1B) (Immunotech)
3. Nuclear Factor Kappa B by western blot of peripheral blood mononuclear cells
4. Genes and proteins involved in inflammatory response will be determined by real time polymerase chain reaction (PCR) and Western blot analysis (MCP-1, TF and TFPI, as markers of inflammation and LRP and the LDL receptor as lipoproteic receptors). Moreover, the expression metalloproteases and their activity will also be analysed.

All variables (primary and secondary outcomes) will be measured at baseline and after each intervention period.
Secondary outcome measuresCurrent secondary outcome measure(s) as of 23/05/2012
1. Medical record: a complete medical record will be obtained from all participants, which included data on alcohol intake, smoking and dietary habits. Blood pressure and heart rate will be measured with an electronic apparatus Omron HEM-705CP (Netherlands). Plasma nitric oxide will be measured by a chemiluminescence detector in a NO analyzer (Sievers Instruments, Inc., Boulder, CO).
2. Nutrition assessment and general analyses: all participants will complete a validated nutritional questionnaire at baseline to determine the total quantity of calories ingested in the previous month as well as the proportion corresponding to carbohydrates, lipids and proteins. Overall nutrition will be determined by percentage of ideal weight, lean body mass and body mass index. Waist perimeter will be measured. The proteic nutrition will be determined on the basis of the following parameters: haemoglobin, total lymphocyte count, total proteins, albumin, prealbumin, transferrin and retinol-binding protein. Serum and intraerythrocytary folic acid concentrations will be measured, as well as serum vitamin A, B1, B12, C, E, B-carotenes, Zn, Mg and Se concentrations. Moreover, the following measurements will also be obtained: red blood cell count, hematocrit, mean corpuscular volume, leukocyte count, glucose, creatinine, electrolytes, uric acid, transaminases, lactate dehydrogenase, alkaline phosphatase, gamma-glutamyl transpeptidase and bilirubin.
3. Coagulation tests: the following parameters will also be determined: platelet count, prothrombin time, and plasma fibrinogen
4. Serum lipoproteins and others: total cholesterol, triglycerides, cHDL, cLDL, Apo A1, Apo A2, Apo B, Apo C1, Apo C2, lipoprotein (a), insulin, adiponectin, growth hormone, leptin and homocysteine will be determined.
5. Diet and exercise monitoring: all participants will follow an isocaloric diet prepared according to their personal preferences. The diet will be strictly monitored during the study. Diet compliance will be assessed from 7-days diet records administered before each evaluation. This assessment will be administered by trained personnel. The foods ingested will be converted into nutritional values with the aid of the Professional Diet Balancer software (Cardinal Health Systems, Inc., Edina, MN). Physical activity will also be evaluated with the Minnesota Leisure Time Physical Activity questionnaire which has also been validated in Spain. Control of the diet and physical exercise will be carried out before and after each intervention, the same day on which the clinical examinations are performed and blood is withdrawn for immunologic studies.

All variables (primary and secondary outcomes) will be measured at baseline and after each intervention period.
