BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is one of the most common diseases worldwide. Studies have shown that melatonin, as a regulatory hormone, is effective in different cell protective pathways. We aimed to compare serum melatonin levels of patients with NAFLD with different stages of fibrosis with that of healthy individuals. METHODS In this cross-sectional study patients, aged >20 years with elevated serum liver enzymes and trance abdominal sonographic diagnosis of fatty liver who met the exclusion criteria for NAFLD were included. The participants were categorized into three groups as follows: 1) severe fibrosis (fibrosis > 9.1 kPa and steatosis > 285 dbm), 2) mild-moderate fibrosis (fibrosis: 6-9.0 kPa and steatosis 240-285), and 3) normal group with fibrosis < 5.8 kPa and steatosis < 240 dbm based on Fibroscan evaluation. Five ml of fasting venous blood was taken from each patient and the control group for laboratory assessment. A questionnaire including demographic, anthropometric, laboratories (serum ALT, AST, triglyceride, total cholesterol and melatonin level), and clinical data was completed for all participants. RESULTS 97 people with a mean±SD age of 42.21 ± 11 years were enrolled. 59 (60.0%) patients were women. we observed that the melatonin levels were increased by advancing fibrosis. Based on control- attenuated parameter results the melatonin levels significantly differed between the healthy individuals and patients with severe steatosis. There was a direct association between increased melatonin levels and liver enzymes. CONCLUSION As a regulatory hormone, melatonin may directly be associated with liver cell injuries. Therefore, considered regulatory substances such as melatonin either diagnostic or therapeutic can improve the patients’ outcome.

CONTEXT: Due to its good correlation to glycemic clamp, HOMA-IR has been widely utilized as insulin resistance index in clinical and epidemiological studies involving non-alcoholic fatty liver disease carriers. However, values used for this parameter have shown large variability. OBJECTIVE: To identify the HOMA-IR cut value that best distinguishes non-diabetic non-alcoholic fatty liver disease patients from a control group. METHODS: One hundred sixteen non-alcoholic fatty liver disease patients were studied, diagnosed by clinical, biochemical, and liver image or biopsy criteria, and 88 healthy individuals, without any liver disease and testing for oral glucose tolerance within normality. These groups did not differ in age and gender. All were submitted to oral glucose tolerance test and blood samples were collected for glucose and insulin measurements by immunofluorometric method. HOMA-IR was calculated according to the formula: fasting insulin (µU/L) x fasting glucose (nmol/L)/22.5. RESULTS: NAFLD patients showed higher insulin, glycemia, and HOMA-IR values than control group, even when excluding glucose intolerant and diabetes mellitus patients by their glycemic curves. HOMA-IR 75th percentile for control group was 1.78 and the best area under the curve index was obtained for HOMA-IR values of 2.0 [AUC= 0.840 (0.781-0.899 CI 95%), sensitivity (Se): 85%, specificity (Sp): 83%] while value 2.5 showed best specificity without important loss in sensitivity [AUC=0,831 (0.773-0.888) Se = 72%, Sp = 94%]. CONCLUSION: HOMA-IR values above or equal to 2.0 or 2.5 show enhanced diagnostic value in distinguishing non-alcoholic fatty liver disease carriers from control group individuals.

Alcoholic Fatty Liver Disease

Purpose Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease which has become a public health concern, whose growing prevalence has been reported as around 33.9% in Iran. As oxidative stress plays a crucial role in the pathogenesis of NAFLD, antioxidant compounds such as quercetin could ameliorate the side effect of oxidative stress. The aim of the current study was to assess the effect of quercetin on lipid profile, liver enzymes and inflammatory indices in NAFLD patients. Design/methodology/approach In a randomized, double-blind, placebo-controlled trial conducted as a pilot study, 90 patients with NAFLD were supplemented with either a quercetin or a placebo capsule twice daily (500 mg) for 12 weeks. Both groups were advised to follow an energy-balanced diet with physical activity recommendations. Blood sample was obtained for laboratory parameters at baseline and the end of week 12. Findings At the end of the follow-up, quercetin group had significantly greater reduction in anthropometric parameters, cholesterol (−15 ± (−41, 0.00) in Q group versus −1± (−8, 2) in control group, p = 0.004), TG (−56.7 ± 22.7) in Q group versus −13.4 ± 27.7 in control group, p = 0.04), and tumor necrosis factor-α (TNF-α) (−49.5 ± (−99, 21) in Q group versus −5 ± (−21, 0.30) in the control group, p < 0.0001) compared to the control group. However, changes in fatty liver grade, liver enzymes, as well as high density lipoprotein-cholesterol and high-sensitivity C-reactive protein were not significantly different between the two groups. Originality/value To the best of the authors’ knowledge, this was the first study which assessed the effect of quercetin supplementation on liver enzymes, lipid profile and inflammatory indices of NAFLD patients as a double-blind placebo-controlled pilot study.

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.

AbstractWe aimed to investigate the effects of maternal tadalafil therapy on fetal programming of metabolic function in a mouse model of fetal growth restriction (FGR). Pregnant C57BL6 mice were divided into the control, L-NG-nitroarginine methyl ester (L-NAME), and tadalafil + L-NAME groups. Six weeks after birth, the male pups in each group were given a high-fat diet. A glucose tolerance test (GTT) was performed at 15 weeks and the pups were euthanized at 20 weeks. We then assessed the histological changes in the liver and adipose tissue, and the adipocytokine production. We found that the non-alcoholic fatty liver disease activity score was higher in the L-NAME group than in the control group (p < 0.05). Although the M1 macrophage numbers were significantly higher in the L-NAME/high-fat diet group (p < 0.001), maternal tadalafil administration prevented this change. Moreover, the epididymal adipocyte size was significantly larger in the L-NAME group than in the control group. This was also improved by maternal tadalafil administration (p < 0.05). Further, we found that resistin levels were significantly lower in the L-NAME group compared to the control group (p < 0.05). The combination of exposure to maternal L-NAME and a high-fat diet induced glucose impairment and non-alcoholic fatty liver disease. However, maternal tadalafil administration prevented these complications. Thus, deleterious fetal programming caused by FGR might be modified by in utero intervention with tadalafil.

Abstract Background Ectopic hepatic lipid accumulation is closely related to the development of insulin resistance, which is regarded as one of the most significant risk factors of non-alcoholic fatty liver disease (NAFLD). The aim of the study was to evaluate and validate the diagnostic value of serum vaspin, NAFLD Fibrosis Score and sonograghic parameters in detection and quantification of liver steatosis and determining further need for liver biopsy or other means to establish NAFLD diagnosis. Methods This study was carried out on 60 patients having bright liver in ultrasonography and 30 healthy persons as controls. The subjects were divided into the following groups; group A: 30 age and sex matched healthy volunteers (control group), group B: 20 patients with fatty liver grade I, group C: 20 patients with fatty liver grade II and group D: 20 patients with fatty liver grade III. Results serum vaspine levels and NAFLD fibrosis score, were significantly higher in patients than in controls with p-value:&lt;0.001. There was a significant positive correlation between NAFLD fibrosis score and serum vaspin and ultrasonographic findngs of NAFLD with p-value: &lt;0.001. Conclusion Vaspin seem to be the most suitable non-invasive biomarker in predicting both intrahepatic lipid contents in NAFLD group.

Objective: The aim of this study is to identify the relationship between carotid intima-media thickness (c-imt) and non-alcoholic fatty liver disease (NAFLD), and to determine whether NAFLD is an independent predictor for the progression of atherosclerosis.  Method: This is a prospective randomized controlled study. 103 NAFLD patients who have hepatosteatosis with grade II and above were enrolled in this study. Patients were divided into NAFLD with metabolic syndrome (MS) and NAFLD without MS groups and compared with 50 healthy people. Basal demographic characteristics and C-imt of all patients and control group were measured.  Results: C-imt and carotid cross sectional area rates in the NAFLD groups were significantly higher than those in the control group. The mean and max. c-imt levels were significantly higher in the NAFLD group with metabolic syndrome (p<0,001). Homeostatic Model of Assessment-Insulin Resistance (HOMA-IR) levels were increased in the group with metabolic syndrome than those in the group without metabolic syndrome, with statistical significance (p<0.001). There was no difference in c-imt levels between HOMA-IR positive and negative groups (p=0.254) in patients with NAFLD and without metabolic syndrome. There was only a mild positive corelation between c-imt levels and high sensitive C-Reactive protein (hs-CRP) levels in metabolic syndrome positive group (p=0.026 r=0.30).  Conclusion: NAFLD was a significant predictor to determine the increased risk of carotid atherosclerosis.

AbstractNon-alcoholic fatty liver disease (NAFLD) includes a range of disorders from simple steatosis to non-alcoholic steatohepatitis. There is no proven drug treatment for NAFLD, and diet modification is considered part of the main line of treatment for this disease. The aim of this study was to investigate the efficacy of garlic supplementation in NAFLD patients. The effect of garlic powder supplementation on hepatic steatosis, liver enzymes and lipid profile was investigated in NAFLD patients. Ninety NAFLD patients were randomly assigned to take either a garlic powder supplement or a placebo for 12 weeks. The treatment group received four tablets of garlic daily (each tablet contained 400 mg garlic powder). The control group received four tablets of placebo (each placebo contained 400 mg starch). At the end of the study, hepatic steatosis was significantly reduced in the treatment group compared with the control group (P = 0·001). In addition, a significant decrease was seen in the serum concentration of alanine transaminase (P < 0·001), aspartate transaminase (P = 0·002), γ-glutamyltransferase (P = 0·003) as well as total cholesterol (P = 0·009), TAG (P < 0·001), HDL-cholesterol (P < 0·001) and LDL-cholesterol (P = 0·01) in the treatment group compared with the control group. No significant difference was seen between the two groups in serum concentration of alkaline phosphatase. Overall, garlic powder supplementation improved hepatic features and lipid profile among NAFLD patients.

Background: Non-alcoholic fatty liver disease (NAFLD) has emerged as the most common liver problem in the western world and is a clinicopathologic entity increasingly recognized as a major health burden in developed countries. Different laboratory tests are extremely useful in achieving a better understanding of diseases, and thereby, allow making decision for better management. The examination of different biochemical parameters usually provides excellent clues to the cause of the disease. The present study was conducted with the aim to assess the biochemical markers in Non alcoholic fatty liver disease (NAFLD) patients in Nepalese population.Methods: The biochemical parameters were investigated in 75 NAFLD patients, and 70 normal participants. The diagnosis of hepatic steatosis was established by abdominal ultrasound examination. All patients diagnosed as NAFLD were investigated for biochemical parameters and see the relationship between NAFLD and control was studied.Results: The findings of all biochemical parameters were raised in NAFLD patients in comparison with non-fatty liver control group and the differences were found to be statistically (P value less than 0.005) significant.Conclusions: NAFLD is associated with changes in biochemical parameters in cases of NAFLD. Its early detection will help in modifying the disease course, delaying complications and will also play a major role in preventive cardiology.Ann. Clin. Chem. Lab. Med. 2016:2(2);15-20
