Background: Anorexia, limitation in the intake of some nutrients, loss of nutrients during dialysis, and extensive inflammation are important causes of malnutrition in hemodialysis patients. For this reason, this study reviews the status of macro- and micronutrient intake in these patients as compared to Dietary Reference Intake (DRI) values.
Methods and Materials: This cross-sectional study was performed on 75 hemodialysis patients referred to the dialysis department of Vasei Hospital, Sabzevar, Iran. After measuring height and body weight, nutrient intake of each patient was determined using 24-hour food recall method for two consecutive days (one day on and one day off dialysis) and the frequency of meals was recorded. Nutrient intake of each individual was determined using Nutritionist IV software. Data were analyzed by descriptive statistics and one-sample t-test at the significance level p < 0.05.
Results: The mean BMI of patients in this study was 20.04±3.38 kg/m2. The mean energy intake was 1767.98±373.85 and 1816.76±433.16 kcal in women and men, respectively, and the mean protein intake was 67.92±21.11 and 69.30±21.38 g per day in men and women, respectively. Also, in this study, the intake of all nutrients, except vitamins B1, B3, B12, and iron, was less than the recommended standard in hemodialysis patients (p < 0.05).
Conclusion: Based on the findings of this study, the intake of most water- and fat-soluble vitamins and minerals was less than the recommended standard in hemodialysis patients.

Background and Purpose: Research on non-hemodialysis patients has shown that ω3-fatty acid supplement can reduce the concentration of serum Lp(a). Therefore the present study was designed to investigate the effects of ω3-fatty acid supplement on serum lipids and lipoproteins in hemodialysis patients. Methods and Materials: This double-blind randomized clinical trial was conducted on 40 hemodialysis patients in 2008 in Vase’i Hospital in Sabzevar Iran; they were randomly assigned to either ω3-fatty acid supplement or placebo group. Patients in the ω3-fatty acid supplement group received 2080 mg ω3-fatty acid daily as 4 capsules while the placebo group received 4 corresponding placebo capsules containing MCT oil. At baseline and the end of week 10 of the study 5 ml blood samples were collected from each patient after a 12 to 14-hour fasting before dialysis; their serum triglyceride total cholesterol LDL-C HDL-C and Lp(a) were measured. The obtained data were analyzed in SPSS using Chi-square t-test paired t-test and ANOVA. Results: Serum triglyceride concentration were 11332 and 10919 in the supplement and placebo groups respectively in the beginning; the amounts decreased to 10125 and 11517 at the end of week 10. The reduction was significant in the supplement group (p
