Hydrogen enriched water for mitochondrial and inflammatory myopathiesScientific Research
Open-label trial and randomized, double-blind, placebo-controlled, crossover trial of hydrogen-enriched water for mitochondrial and inflammatory myopathies
Molecular hydrogen is important in more than 30 animal models, especially in oxidative stress-mediated diseases and inflammatory diseases. Furthermore, hydrogen effects have been reported in human type 2 diabetes, hemodialysis, metabolic syndrome, radiotherapy for liver cancer, and brainstem infarction. The hydrogen effect has been attributed to specific radical scavenging activities to eliminate hydroxyl radicals and peroxynitrite, as well as signal-modulating activities, but the detailed molecular mechanisms remain elusive. Hydrogen is a safe molecule, mainly produced by gut bacteria in rodents and humans, and no adverse effects have been recorded.
We conducted an open-label study in 5 patients with progressive muscular dystrophy (PMD), 4 patients with polymyositis/dermatomyositis (PM/DM) and 5 patients with mitochondrial myopathy drinking 1.0 liters of rich daily Hydrogen water for 12 weeks (MM). Serum parameters and 8-isoprostaglandin were measured 18 times in urine every 4 weeks. Next, we conducted a randomized, double-blind, placebo-controlled, crossover study of 0.5 liters of hydrogen-rich water per day or placebo water in 10 patients with DM and 12 patients with MM for 8 weeks with 18 measurements each Serum parameters. 4 weeks.
No objective improvement or worsening of clinical symptoms was observed in the open-label study. However, we observed significant effects on lactate to pyruvate ratios in PMD and MM, fasting blood glucose in PMD, serum matrix metalloproteinase-3 (MMP3) in PM/DM, and serum triglycerides in PM/DM. influences. No objective clinical effect was observed in the double-blind study, but a significant improvement in lactate in MM was noted. The lactate to pyruvate ratio in MM and MMP3 in DM also showed good responses, but not statistically significant. No adverse effects were observed in all studies, except for a hypoglycemic event in one MELAS patient receiving insulin, which was resolved by reducing the insulin dose.
Hydrogen-rich water improves mitochondrial dysfunction in MM and inflammatory processes in PM/DM. The less pronounced effect in the double-blind study may be due to the lower amount of hydrogen administered and the shorter observation period compared to the open-label study, suggesting a threshold or dose-response effect of hydrogen.
