Hemodialysis employing molecular hydrogen (H2)-enriched dialysis solution rendered by water electrolysis (E-HD), has been reported to alleviate dialysis-related fatigue, but its association with metabolic profiles remains unclear. Eighty-one patients undergoing standard HD were classified into 3 groups [Group A (n = 25, 30.9%): fatigue with activity reduction—subgroups A1: chronic persistent fatig

Background Nephrotoxicity is a common adverse effect of many chemotherapeutic agents and represents a major dose- limiting factor in cancer treatment. Therefore, developing effective renoprotective strategies is urgently needed. Molecular hydrogen (H2) has emerged as a therapeutic agent with potent antioxidant and anti-inflammatory properties, selectively scavenging hydroxyl radicals and alleviati

Mitochondria originated from aerobic bacteria in endosymbiosis. Through this symbiosis, eukaryotes acquired an efficient energy-producing system, but at the cost of exposure to oxidative stress from reactive oxygen species (ROS). Molecular hydrogen (H2) was recently identified as an antioxidant that selectively reduces ROS, such as hydroxyl radicals and peroxynitrite, which are strong oxidants, and

The aim of the review was to examine the main characteristics of hydrogen ion metabolism and its hemostatic function in the human body. For diagnostic purposes, molecular hydrogen (H2) is considered a biological marker. The results of the analysis of therapeutic programs for the clinical use of hydrogen are presented. The use of H2 as a drug in the treatment of more than 170 diseases is also discu

Gentamicin-induced nephrotoxicity primarily results from renal inflammatory cascades and increased oxidative stress. This study aims to examine the effects of hydrogen-rich water (HRW) on gentamicin-induced renal damage in rats. Thirty-two rats were equally divided into four groups, including control (no treatment), hydrogen, gentamicin, and gentamicin+hydrogen. At the end of one week, all animals

Hydrogen is a simple, colorless, and biologically active small molecule gas that can react with reactive oxygen species. Recent research suggests that hydrogen possesses several biological effects, including antioxidant, anti-inflammatory, and anti-apoptotic effects, while exhibiting an extremely high level of safety. Hydrogen application has shown promise in treating a range of acute and chronic

As diabetes rates surge globally, there is a corresponding rise in the number of patients suffering from diabetic kidney disease (DKD), a common complication of diabetes. DKD is a significant contributor to chronic kidney disease, often leading to end-stage renal failure. However, the effectiveness of current medical treatments for DKD leaves much to be desired. Molecular hydrogen (H2) is an antio

Cardiac surgery-associated acute kidney injury (CS-AKI) is a common postoperative complication, mostly due to increasing oxidative stress. Recently, molecular hydrogen (H2 gas), has also been applied to cardiac surgery due to its ability to reduce oxidative stress.

Background: Acute kidney injury and its central pathology, renal ischemia reperfusion injury (IRI), have been studied in many animal models. Although renal IRI has been induced in pig models in many ways, simultaneous bilateral ischemia or unilateral ischemia along with contralateral nephrectomy models only provide data on the renal response to a single ischemia time. Moreover, it has been reporte

Molecular hydrogen (H2) is a colorless and odorless gas. Studies have shown that H2 inhalation has the therapeutic effects in many animal studies and clinical trials, and its application is recommended in the novel coronavirus pneumonia treatment guidelines in China recently.
