Effect of vitamin C supplementation on serum uric acid in patients undergoing hemodialysis: a randomized controlled trial.

Introduction: Clinical studies of recent years have shown that hyperuricemia is associated with poor outcomes such as cardiovascular mortality and dialysis inadequacy in patients undergoing hemodialysis. Our study investigated the effect of vitamin C supplementation on serum uric acid levels in hemodialysis patients.

Materials And Methods: This randomized placebo-controlled trial was conducted on 172 hemodialysis patients.

Effect of Vitamin C Supplementation on C-reactive Protein Levels in Patients Undergoing Hemodialysis: A Randomized, Double Blind, Placebo-Controlled Study.

Background: Chronic inflammation is the most important cause of cardiovascular disease in patients undergoing hemodialysis, and vitamin C as a major antioxidant which could be effective to suppress inflammation.

Objectives: This study was performed to evaluate the effect of vitamin C supplementation on C-reactive protein levels in patients undergoing hemodialysis.

Patients And Methods: This randomized, placebo-controlled and double-blind trial was conducted on 151 patients on hemodialysis who were divided randomly by lottery method to three identical groups.

The effect of vitamin C on parathyroid hormone in patients on hemodialysis with secondary hyperparathyroidism: a double blind, placebo-controlled study.

Background: Secondary hyperparathyroidism (SHPT) is a prevalent disorder in patients with chronic kidney disease. It is proffered that there is a contradictory relation between serum level of vitamin C and parathyroid hormone (PTH) in hemodialysis patients with secondary hyperparathyroidism.

Objectives: The goal of this study was to assess the effects of the supplemental vitamin C on parathyroid hormone among hemodialysis patients with secondary hyperparathyroidism.

Different aspects of fatigue experienced by patients receiving maintenance dialysis in hemodialysis units.

Background: Fatigue, a common symptom reported by patients receiving dialysis, is a multidimensional and subjective experience which is readily understood by individuals but difficult to measure.

Objectives: This study was performed to identify the prevalence of differential aspects of fatigue among patients receiving maintenance dialysis.

Patients And Methods: The cross-sectional study was conducted in two hemodialysis wards in Tehran with a sample of 163 participants.

Effect of eye mask on sleep quality in patients with acute coronary syndrome.

Introduction: Sleep is one of the basic human needs and sleep deprivation causes nu-merous adverse effects on the human body and mind. Due to reduced sleep quality in patients with acute coronary syndrome, this study was carried out to determine the effect of eye mask on sleep quality in patients with acute coronary syndrome.

Methods: In this two-group controlled clinical trial, sixty patients with acute coronary syndrome in the coronary care units of Baqiyatallah Hospital in Tehran in 2010 were selected by purposeful sampling method and randomly allocated to two groups of case and control.
