TL;DR
Drinking hydrogen-rich water may protect rats from kidney damage caused by the chemotherapy drug cisplatin, as shown by MRI scans.
Key Finding
Rats that drank hydrogen-rich water before receiving cisplatin chemotherapy showed significantly better kidney function markers and less kidney damage on imaging compared to rats that drank regular water.
Summary
Researchers gave rats a chemotherapy drug called cisplatin, which is known to damage the kidneys. Some rats drank regular water while others drank hydrogen-rich water (water with extra hydrogen gas dissolved in it). Using a special MRI imaging technique, the researchers found that rats drinking hydrogen-rich water showed better kidney function markers and less kidney damage compared to rats drinking regular water. The researchers believe hydrogen may work by reducing harmful oxygen molecules that damage cells.
Practical Takeaway
This is an early-stage animal study suggesting hydrogen-rich water may help protect against chemotherapy-related kidney damage. However, this was only tested in rats, not humans, so it's unclear whether these results would apply to people. Anyone undergoing chemotherapy should discuss any supplements or special waters with their oncologist before use.
Abstract
The aim of this study was to assess the mechanism of the protective effect of hydrogen-rich water (HW) against cisplatin (CP)-induced nephrotoxicity in rats using blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI). Apparent transverse relaxation time-weighted images (T2 WI) were acquired in 28 rats. The control group (n = 7) had free access to standard water (SW) and no CP injection. The CP group (n = 7) had free access to SW and was given a CP injection on day 0. The CP+HW group (n = 7) had free access to HW and had a CP injection. The HW group (n = 7) had free access to HW and no CP injection. The apparent transverse relaxation rate (R2) was estimated from T2 WI. In the CP+HW group, the R2 value in the medulla normalized by the value of the day 0 was significantly greater than that in the CP group on days 4 and 7. The creatinine and blood urea nitrogen levels in the CP group were significantly higher than those in the control, CP+HW, and HW groups. BOLD MRI may be useful for demonstrating the change in R2 in CP-induced nephrotoxicity in rats. The changes in the CP+HW group were suspected to be due to a reduction of cytotoxic oxygen radicals.
