Emerging Clinical Applications for Molecular Hydrogen.

This narrative review examined the current clinical experience with inhaled H₂ therapy, discusses key challenges and limitations in the existing literature, and identifies areas of interest for future research, including the development of a validated delivery system to enable broader clinical investigation and application of H₂ therapy. Published clinical findings are encouraging, although data are limited by small sample sizes, methodological variability, and the absence of standardized and validated commercially available delivery systems. The reviewed evidence adds support for molecular hydrogen's therapeutic potential across the conditions, mechanisms, or outcomes examined.

[Suppression of abdominal aortic aneurysm by hydrogen through chemokine-like factor1].

In male Sprague-Dawley rats, hydrogen which may contribute to reduce rCklf1 expression prevents infiltration of inflammation and expression of MMP2 thus decreasing destruction and degradation of elastic fibers, therefore ameliorates development of AAA. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.

[Hydrogen-rich saline attenuates hyperalgesia and reduces cytokines in rats with post-herpetic neuralgia via activating autophagy].

In rats, compared with PHN group,the rats in the PHN-H₂ group and PHN-H₂-Rap group showed increased PWT,decreased levels of TNF-α,IL-1β and IL-6,further up-regulated expressions of LC3 and beclin 1 as wel as P62 expression. These results are preclinical and suggest molecular hydrogen's therapeutic potential in the condition studied. Further human research is needed to establish clinical effectiveness.

Microbial hydrogen economy alleviates colitis by reprogramming colonocyte metabolism and reinforcing intestinal barrier.

In mice, exogenous H₂ reprograms colonocyte metabolism by regulating the H₂-gut microbiota-SCFAs axis and strengthens the intestinal barrier by modulating specific mucosa-associated mucolytic bacteria, wherein improved microbial hydrogen economy alleviates colitis. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.

Hydrogen-rich saline alleviates cardiomyocyte apoptosis by reducing expression of calpain1 via miR-124-3p.

In mice, it was also found that compared with the hydrogen-rich saline group, overexpression of calpain1 increased caspase-3 activities, promoted cleaved-caspase3 and Bax protein expressions, and correspondingly decreased Bcl-2, further reducing cell viability. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
