Scientific titleEffect of probiotic yoghurt comprising L. plantarum strain TENSIA on blood indices and intestinal microflora of healthy volunteers: A randomised controlled crossover trial
Study acronymJOG3
Study objectivesThe consumption of yoghurt containing probiotic L. plantarum strain TENSIA has positive impact on blood indices of healthy volunteers.
Ethics approval(s)Ethics Review Committee on Human Research of the University of Tartu approved on the 17th January 2010 (ref: 200-T4)
Health condition(s) or problem(s) studiedBlood indices, intestinal microflora
InterventionThe consumption once a day 150 g of probiotic yoghurt versus regular yoghurt for 3 weeks. Probiotic yoghurt containing either Lactobacillus plantarum strain TENSIA (10^9 colony forming units [CFU]/g). After two-week washout period, volunteers are crossed over to another three weeks of probiotic yoghurt or control yoghurt administration. Fasting blood samples are collected.
Intervention typeOther
Primary outcome measure1. The health indices of study participants (height, weight, body mass index, blood pressure) assessed at the recruitment, after 3 weeks of probiotic treatment, after washout and after 3-week placebo treatment
2. The self-reported questionnaire containing questions on welfare, and habitual gastrointestinal symptoms (abdominal pain, flatulence, bloating, and stool frequency), measured once a week during the trial
3. Haematological indices (haemoglobin, white blood cell count, red blood cells, platelets), plasma glucose, albumin, total cholesterol, low density lipoprotein (LDL)-cholesterol, high density lipoprotein (HDL)-cholesterol, triglycerides, high sensitivity C reactive protein (hs-CRP) and interlukin (IL)-6 measured at the recruitment, after 3 weeks of probiotic treatment, after washout and after 3-week placebo treatment
Secondary outcome measuresCirculation of polyamines in host, oxidised low density lipoprotein (oxLDL), 8-isoprostanes, adiponectine, leptin, cytokines and growth factors (IL1 alfa, IL1beta, IL2, IL4, IL6, IL8, IL10, VEGF, EDG, ITFgamma, TNFalfa, MCP-1), osteoprotegerin
