AIM: To evaluate the impact of the consumption of a synbiotic product on the antioxidative activity markers of blood in asymptomatic H. pylori-colonized persons.

METHODS AND RESULTS: Fifty-three healthy adult volunteers without gastric symptoms participated in a randomized, double-blind placebo-controlled study. The crossover consumption of the enterocoated capsules containing antioxidative Lactobacillusfermentum ME-3, Lact. paracasei 8700:2 and Bifidobacterium longum 46 with Raftilose P95 lasted for 3 weeks and did not change the H. pylori colonization. In H. pylori-positive subjects the sera values of total antioxidative status (TAS) were significantly lower compared to H. pylori-negative subjects (0.97 vs 1.05 mmol l(-1), P = 0.008). After the consumption of the synbiotic, TAS values (0.97 vs 1.03 mmol l(-1), P = 0.004) increased, while the ratio between oxidized and reduced glutathione (0.035 vs 0.030, P = 0.016) decreased in H. pylori-positive subjects.

CONCLUSIONS: The consumption of a synbiotic containing an antioxidative probiotic strain improved the reduced systemic antioxidative activity in H. pylori-colonized asymptomatic subjects.

SIGNIFICANCE AND IMPACT OF THE STUDY: A synbiotic product containing an antioxidative probiotic strain may be useful in the reduction of systemic oxidative stress in H. pylori infection.
