A two-arm randomized open labeled controlled clinical trial was conducted on 50 patients with non-alcoholic fatty liver disease (NAFLD). Participants were assigned to take either a lifestyle modification (LM), or LM +30 g/day brown milled flaxseed for 12 weeks. At the end of the study, body weight, liver enzymes, insulin resistance and hepatic fibrosis and steatosis decreased significantly in both groups (p< 0.05); however, this reduction was significantly greater in those who took flaxseed supplementation (p < 0.05). The significant mean differences were reached in hepatic markers between flaxseed and control group, respectively: ALT [-11.12 compared with -3.7 U/L; P< 0.001], AST [-8.29 compared with -4 U/L; p < 0.001], GGT [-15.7 compared with -2.62 U/L; p < 0.001], fibrosis score [-1.26 compared with -0.77 kPa; p = 0.013] and steatosis score [-47 compared with -15.45 dB/m; p = 0.022]. In conclusion, flaxseed supplementation plus lifestyle modification is more effective than lifestyle modification alone for NAFLD management.

Background:Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. The pathogenesis of this disease is closely associated with obesity and insulin resistance. Ginger can have hypolipidemic and antioxidant effects, and act as an insulinsensitizer.Objectives:The aim of this study was to evaluate the effects of ginger supplementation in NAFLD management.Patients and Methods:In a randomized, double-blind, placebo-controlled clinical trial, 44 patients with NAFLD were assigned to take either two grams per day of a ginger supplement or the identical placebo, for 12 weeks. In both groups, patients were advised to follow a modified diet and physical activity program. The metabolic parameters and indicators of liver damage were measured at study baseline and after the 12 week intervention.Results:Ginger supplementation resulted in a significant reduction in alanine aminotransferase, γ-glutamyl transferase, inflammatory cytokines, as well as the insulin resistance index and hepatic steatosis grade in comparison to the placebo. We did not find any significant effect of taking ginger supplements on hepatic fibrosis and aspartate aminotransferase.Conclusions:Twelve weeks of two grams of ginger supplementation showed beneficial effects on some NAFLD characteristics. Further studies are recommended to assess the long-term supplementation effects.

Background: This study aimed to evaluate the safety and efficacy of 2 forms of vitamin D supplementation on oxidative stress and weaning from the ventilator in patients with traumatic injury and vitamin D deficiency. Methods: Seventy-two patients were randomly divided into 3 groups: receiving 50,000 IU pearl cholecalciferol daily for 6 days, 1 intramuscular injection of 300,000 IU of cholecalciferol, or a control group that did not receive any supplement. Duration of mechanical ventilation, body composition, and biochemical biomarkers were measured before and after the intervention. Result: At the end of the study, the mean serum 25(OH)D increased in the intervention groups compared with the control group (P < .05). The interleukin 6, erythrocyte sedimentation rate, C-reactive protein levels, Sequential Organ Failure Assessment score, duration of mechanical ventilation, and length of intensive care unit admission significantly decreased; however, total antioxidant capacity concentration did not differ significantly between the 2 intervention groups. Among the body composition variables, extracellular water ratio changes were statically different in oral vitamin D group compared with the control group (P = .001). No side effects were reported with the supplements. Conclusions: Vitamin D administration improved clinical signs and biochemical biomarkers in a small group of patients with traumatic injury. Well-designed multicenter clinical studies with longer intervention duration are necessary for this field.
