Recently, molecular hydrogen (H2) was demonstrated to be a selective scavenger for the hydroxyl radical.
Although its etiology is unknown, the hydroxyl radical has been suggested to be involved in the pathogenesis of Rheumatoid arthritis( a chronic inflammatory disease characterized by the destruction of bone and cartilage..).
We hypothesized that molecular hydrogen H2 in the water could complement conventional therapy by reducing the oxidative stress in Rheumatoid arthritis
The method to prepare water containing extremely high concentration of molecular hydrogen H2 has been developed.
20 patients with rheumatoid arthritis (RA) drank 530 ml of water containing 4 to 5 ppm molecular hydrogen (high H2) water every day for 4 weeks. After a 4-week wash-out period, the patients drank the high molecular hidrogen H2 water for another 4 weeks.
Urinary 8-hydroxydeoxyguanine (8-OHdG) and disease activity (DAS28, using C-reactive protein [CRP] levels) was estimated at the end of each 4-week period.
Drinking high molecular hydrogen H2 water seems to raise the concentration of molecular hydrogen H2 more than the H2 molecular hydrogen saturated (1.6 ppm) water in vivo.
Urinary 8-OHdG was significantly reduced by 14.3% (p < 0.01) on average. DAS28 also decreased from 3.83 to 3.02 (p < 0.01) during the same period.
After the wash-out period, both the urinary 8-OHdG and the mean
DAS28 decreased, compared to the end of the drinking period.
During the second drinking period, the mean DAS28 was reduced from 2.83 to 2.26 (p < 0.01). Urinary 8-OHdG was not further reduced but remained below the baseline value.
All the 5 patients with early rheumatoid arthritis (duration < 12 months) who did not show antibodies against cyclic citrullinated peptides (ACPAs) achieved remission, and 4 of them became symptom-free at the end of the study.
Conclusions: The results suggest that the hydroxyl radical scavenger -molecular hydrogen H2(dissolved in water) effectively reduces oxidative stress in patients with rheumatoid arthritis. The symptoms of rheumatoid arthritis were significantly improved with high molecular hidrogen H2 water.
