The role of melatonin treatment in chronic kidney disease.
Summary of "The role of melatonin treatment in chronic kidney disease."
The pineal hormone melatonin plays a major role in circadian sleep-wake rhythm. Patients with Chronic Kidney Disease (CKD), especially those who are on hemodialysis, frequently suffer from sleep disturbances. In this review an overview is given of the classification of stages of chronic kidney disease, followed by a presentation of the circadian rhythm disorders in renal disease involving sleep disturbances in relation to melatonin deficiency. The therapeutic benefit of melatonin treatment in sleep disorders related to chronic kidney disease including the controlled trials solving this topic, is described. Furthermore, the beneficial effect of melatonin on blood pressure alterations in CKD states and the protection of melatonin in oxidative stress and inflammation in renal disorders are explored. Finally a hypothetic model is described for the relation between circadian rhythm disorders and CKD.

Renal Insufficiency, Chronic
Conditions in which the KIDNEYS perform below the normal level for more than three months. Chronic kidney insufficiency is classified by five stages according to the decline in GLOMERULAR FILTRATION RATE and the degree of kidney damage (as measured by the level of PROTEINURIA). The most severe form is the end-stage renal disease (CHRONIC KIDNEY FAILURE). (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002)
Kidney Failure, Chronic
The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.
Receptor, Melatonin, Mt1
A melatonin receptor subtype that is primarily found in the HYPOTHALAMUS and in the KIDNEY.
A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
A family of G-protein-coupled receptors that are specific for and mediate the effects of MELATONIN. Activation of melatonin receptors has been associated with decreased intracellular CYCLIC AMP and increased hydrolysis of PHOSPHOINOSITIDES.
Much attention recently has been focused on stem cell technology as a possible alternative modality of treatment of a variety of diseases. Chronic kidney disease is a serious health problem and most c...
Ischemia-reperfusion (I/R) injury induces the generation of reactive oxygen species (ROS) which affect many organs. This study was designed to investigate the roles of melatonin and 1,25-dihydroxyvita...
This review summarizes new findings related to beneficial effects of melatonin (N-acetyl-5-methoxytryptamine) on reproductive physiology. Recently many researchers have begun to study the local role o...
