Impaired Antioxidant Status in Non-Organ Specific Autoantibody Positive Patients with Non-Alcoholic Fatty Liver Disease

Abstract. Aim: The fruit of the pomegranate (Punica granatum) has a high content of polyphenols and is renowned for its antioxidant capabilities. In particular, it is recognized as reducing oxidative stress and, therefore, playing a productive role in obstructing the pathogenesis of fatty liver disease. The aim of the present study was to evaluate the effects of consumingpomegranate juice (high in antioxidant content) and orange juice (low in antioxidant content) when combined with a hypocaloric diet on liver enzymes and the antioxidant status of patients. Methods: In a randomized clinical trial, 65 patients who exhibited non-alcoholic fatty liver disease (NAFLD) at a mean age of 39+/-8 years received 250 mL pomegranate juice or orange juice per day as a substitute for two servings of fruit in a hypocaloric diet over a period of 12 weeks. The subjects’ levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total antioxidant capacity (TAC), malondialdehyde (MDA) and tumor necrosis factor-α (TNF-α) were measured at the beginning and end of the study. Results: At the end of the study, the levels of liver enzymes and body mass index (BMI) had significantly decreased in both groups. A significant increase in TAC was also observed in the subjects in the pomegranate group (p <0.01). Conclusion: Consumption of fruits that are high in antioxidants could represent a useful means to improve the antioxidant status of NAFLD patients who follow a hypocaloric diet.

Abstract. Some epidemiological evidence suggests an inverse correlation between non-alcoholic fatty liver disease (NAFLD) frequency and vitamin D levels. Likewise, a beneficial effect of vitamin D on diabetes mellitus (DM) and insulin resistance has been observed, but this is an unsolved issue. Thus, we aimed to investigate the prevalence of hypovitaminosis D in a NAFLD Brazilian population and its association with disease severity and presence of comorbidities. In a cross-sectional study, the clinical, biochemical and histological parameters of 139 NAFLD patients were evaluated according to two different cut-off points of serum 25-hydroxyvitamin D levels (20 ng/mL and 30 ng/mL). The mean age of the population was 56 ± 16 years, most patients were female (83%), 72% had hypertension, 88% dyslipidemia, 46% DM, 98% central obesity, and 82% metabolic syndrome. Serum vitamin D levels were < 30 ng/mL in 78% of the patients, and < 20 ng/mL in 35%. The mean vitamin D level was 24.3 ± 6.8 ng/mL. The comparison between the clinical, biochemical and histological characteristics of the patients according to the levels of vitamin D showed no significant difference. Most patients with NAFLD had hypovitaminosis D, but low vitamin D levels were not related to disease severity and the presence of comorbidities.

Objectives: To evaluate the frequency of non-alcoholic fatty liver disease, the retinol serum levels, lipid profile, and insulin resistance in overweight/obese children. To relate these biochemical variables with the risk of this disease in the population studied. Methods: The study was cross-sectional and prospective, with 46 overweight/obese school children (28 female, 18 male; mean age 8.6 years). The control group consisted of 45 children, paired by age and gender. Hepatic steatosis, evaluated by ultrasound, was classified as normal, mild, moderate, or severe. Also evaluated were serum retinol levels; thiobarbituric acid reactive substances; lipid profile; and fasting glucose and serum insulin levels, used for the calculation of the Homeostasis Model Assessment. Results: Hepatic ultrasound alterations were found in 56.5% and 48,9% of the overweight/obese and control group children, respectively. Presence of obesity was associated with high levels of triglycerides (OR = 4.6; P = 0.002). In the studied children, the risk of steatosis was related to a trend to a higher percentage of retinol inadequacy (OR = 2.8; p = 0.051); there was no association with thiobarbituric acid reactive substances, lipid profile, or insulin resistance. Conclusions: The high frequency of non-alcoholic fatty liver disease in both groups, evaluated by hepatic ultrasound, in low-socioeconomic level children, independent of nutritional condition and without significant association with insulin resistance, emphasizes that especially in developing countries, other risk factors such as micronutrient deficiencies (e.g. vitamin A) are involved.
