TL;DR
A hydrogen-releasing compound protected against chemotherapy-related hearing loss by reducing inflammation, cell death, and oxidative stress.
Key Finding
Magnesium hydride protected hearing and preserved inner ear cells in mice treated with cisplatin, working through antioxidant, anti-inflammatory, and cell-protective mechanisms.
Summary
Cisplatin is a cancer drug that often causes permanent hearing loss as a side effect. In this mouse study, researchers tested whether magnesium hydride (a compound that releases hydrogen) could protect hearing. The treatment reduced damage to sound-sensing cells in the inner ear, decreased harmful molecules called free radicals, and reduced inflammation—all factors that contribute to cisplatin's hearing damage.
Practical Takeaway
While this animal study suggests hydrogen-releasing compounds may help prevent chemotherapy-related hearing loss, it is not yet evidence that hydrogen water would have the same effect in humans. The study used a specific compound (magnesium hydride) in mice, not the molecular hydrogen found in hydrogen water, so direct application to consumer hydrogen products is unclear. Clinical trials in humans would be needed before any recommendations could be made for cancer patients.
Abstract
Cisplatin is a widely-used chemotherapeutic agent, but its dose-limiting ototoxicity often results in irreversible hearing loss. The pathogenesis involves oxidative stress, apoptosis, DNA damage, and inflammatory responses, yet effective preventive strategies remain limited. Here, we demonstrate that magnesium hydride (MgH2), a hydrogen-releasing compound, provides robust protection against cisplatin-induced hearing loss. Our results showed that MgH2 protected auditory function and preserved cochlear hair cells in vivo. Furthermore, it significantly attenuated cisplatin-induced oxidative stress and apoptosis in cultured HEI-OC1 (House Ear Institute-Organ of Corti 1) cells and cochlear explants. Notably, MgH2 suppressed NOD-like receptor family pyrin domain containing 3 (NLRP3)-mediated inflammatory cascades, thereby limiting downstream inflammatory damage. These findings revealed that MgH2 alleviated cisplatin-induced hearing loss through integrated antioxidant, anti-inflammatory, and anti-apoptotic pathways, with NLRP3 identified as a critical regulatory molecule. Collectively, our study provides compelling evidence for MgH2 as a potential therapeutic candidate for the prevention of cisplatin-induced hearing loss.
