Effect Of Melatonin On The Clinical Outcome In Pediatric Hemodialysis Patients

A Prospective, randomized, double-blinded, placebo-controlled trial will be conducted at the pediatric dialysis unit, Children's Hospital, Ain Shams University in order to investigate the benefits of melatonin supplementation on oxidative stress, inflammation and to assess sleep quality by using PSQI questionnaire in pediatric hemodialysis patients.

3. Patient demographics, clinical characteristics and full medical and medication history: will be obtained at baseline and every 4 weeks after the beginning of the study.
4. Blood samples will be withdrawn from each patient before the dialysis session for assay of each of the following:

1.Oxidative stress marker malondialdehyde (MDA) by ELISA assay. 2. Inflammatory marker level nuclear factor kappa B (NF-KB) by ELISA assay 3. Complete blood picture (CBC). 4. Lipid profile (total cholesterol(TC), triglycerides(TG), high-density lipoprotein (HDL) and low-density lipoprotein (LDL) 5)Safety will be assessed weekly after the beginning of the study by monitoring the side effects or any adverse drug reactions.
