Patients and Methods : In this double-blind randomized controlled clinical trial study (#IRCT cod; 29363; http://irct.ir/trial/29363), the effect of the omega-3 supplement on uremic pruritus was assessed in 64 chronic hemodialysis patients (using standard 5-D itch scale questionnaire). Patients were surveyed at the hemodialysis department of Imam Khomeini and Razi hospitals in Ahvaz city, Iran. Results : We found that the mean score of itching degree in the intervention and the placebo groups decreased from 3.56 to 1.72 (P0.001) and 3.63 to 3.09 (P0.05) respectively.
