TL;DR
Hydrogen treatment can reduce inflammation and oxidative stress in cells affected by rheumatoid arthritis.
Key Finding
Hydrogen-enriched water reduced oxidative stress markers and blocked key inflammatory signaling pathways (MAPK and NF-κB) in arthritis-affected cells in a mouse model.
Summary
Researchers tested whether molecular hydrogen could reduce inflammation in mice with a type of arthritis similar to rheumatoid arthritis. They found that hydrogen-enriched water appeared to protect cells from damage caused by oxidative stress (harmful molecules that build up in the body) by activating protective enzymes and blocking inflammatory signaling pathways that normally trigger joint damage.
Practical Takeaway
This is early-stage research in mice only, so it cannot yet be applied to human health. While the results suggest hydrogen water may have anti-inflammatory potential for arthritis, human clinical trials would be needed to determine if these effects translate to people with rheumatoid arthritis.
Abstract
Rheumatoid arthritis (RA) is a chronic inflammatory disease which results in progressive destruction of the joint. In this study, we examined if the hydrogen could inhibit inflammation in a mouse model of collagen-induced arthritis (CIA) via oxidative stress on RA-FLSs. Moreover, to identify the mechanisms of action, we evaluated the effect of hydrogen on RA-FLSs development and the expression of pro-inflammatory cytokines and signaling pathways. Based on our result, H2 enriched medium can increase super oxide dismutase (SOD) level following H2O2 treatment and decrease 8-hydroxy-2'-deoxyguanosine (8-OHdG) level. Since H2O2 treatment activates MAPK, NF-κB and TGF-β1 in cells, our study suggested that H2 could inhibit H2O2 activated MAPK and NF-κB activation as well as TGF-β1 expression in treated cells. Taken together, our data suggested that H2 can directly neutralize OH and ONOO- to reduce oxidative stress. Moreover, MAPK and NF-κB pathway also play roles in oxidative damage caused by H2O2 in RA-FLSs. H2 can provide protection to cells against inflammation, which may be related to inhibition of the activation of MAPK and NF-κB.
