Studies on fatty acid-binding proteins. The binding properties of rat liver fatty acid-binding protein.

1. The fluorescent fatty acid probe 11-(dansylamino)undecanoic acid binds to rat liver fatty acid-binding protein with a 1:1 stoichiometry. 2. The binding of the fluorescent probe is competitive with long-chain fatty acids. 3. Binding displacement studies were performed with a wide range of fatty acids and other ligands and identified C16 and C18 fatty acids as the preferred fatty acids for rat liver fatty acid-binding protein. No preference was observed for unsaturated fatty acids within this group. 4. Fatty acyl-CoA binds less well than the corresponding fatty acid.

Diagnosis of early acute fatty liver of pregnancy.

Acute fatty liver of pregnancy (AFLP) is usually diagnosed at autopsy, with severe hepatic failure, or after the appearance of extrahepatic disease. We present an atypical patient with mild AFLP in whom hepatic biopsy allowed earlier diagnosis. A low threshold for liver biopsy in patients not experiencing fulminant disease can afford diagnostic information prior to the onset of serious sequelae.

[Studies on treatment of fatty liver with traditional Chinese medicine].

Great progress has been made in the study of fatty liver with integrated traditional Chinese and western medicine in aspects of diagnosis, treatment and experimental study, etc. Most researches were designed to utilize diagnostic or model replicating method of western medicine to observe the effects or investigate the action mechanism of compound recipe, single Chinese herb or effective ingredients of Chinese herbs on fatty liver. According to the pathological mechanism of traditional Chinese medicine (TCM), fatty liver is characterized by deficiency in nature and repletion in appearance, which involves three Zang viscera such as liver, spleen and kidney and manifests as spleen Qi deficiency, liver and kidney deficiency, phlegm and dampness heaping internally, and Qi stagnation and blood stasis. This facilitates us to use specific recipe or modified recipe to treat fatty liver from the points of integrated traditional Chinese and western medicine and combining syndrome differentiation with disease differentiation. With gratifying achievement, this kind of approach has been the mainstream of the research on fatty liver and many researchers have reached an agreement on this point domestically. Spleen Fortifying and Blood Invigorating Recipe (SFBVER in brief, invented by our institute) can significantly improve the B ultrasound outcome of the liver in patients with fatty liver, with significant difference in B ultrasound scoring between pre-and post-treatment. It can alleviate the patients' symptoms, improve or regain liver function, decrease waist/buttocks ratio and the content of triglyceride and cholesterol in blood. SFBVER is superior to Dongbao Gantai Recipe in general effective rate. Experimental study also reveals that SFBVER can alleviate CCl(4) induced liver cell fatty degeneration and the inflammatory cell infiltration in rats, decrease the activities of ALT and AST, lower the content of triglyceride in liver, recover SOD activity in liver to normal level. The overall efficacy of SFBVER is superior to that of Dongbao Gantai Recipe. Further correlated study should be focused on inventing new preparation of traditional Chinese medicine and investigating its action mechanism with the guiding of the theory of TCM and referring to the latest discovery in fatty liver research in modern medicine.

Critical preservation injury in rat fatty liver is to hepatocytes, not sinusoidal lining cells.

BACKGROUND: Fatty livers are more prone to primary nonfunction after transplantation. We hypothesized that sinusoidal lining cells (SLCs) in fatty livers of obese Zucker rats are more susceptible to ischemia/reperfusion injury than in normal livers. METHODS: Cold University of Wisconsin solution-preserved (30 min or 24 hr) livers from obese and lean Zucker rats were perfused ex vivo for 90 min with oxygenated warm acellular buffer containing hyaluronate. Bile output, alanine transferase, and hyaluronate clearance were measured during reperfusion. Trypan blue was infused at completion of reperfusion to assess cell membrane integrity. Another group of 24-hr preserved livers were reperfused with cold hypoxic buffer to differentiate the effects of preservation from reoxygenation. RESULTS: After 30 min of preservation, fatty livers had significantly decreased flow (1.9 vs. 2.6 ml/g/min), increased resistance, decreased hyaluronate clearance (17 vs. 35 microg/g liver) and lower bile output (13 vs. 42 microl/g) in comparison with normal livers. Hepatocyte and SLC trypan blue uptake were minimal and similar in both groups. After 24 hr of preservation, flow (2.0 vs. 2.0), resistance, hyaluronate clearance, and bile output were similar in both fatty and normal livers. The SLC trypan blue uptake was increased but similar in both groups (22 vs. 20%). In contrast, a significantly greater number of hepatocytes were trypan blue-stained in fatty livers (32 vs. 0.6%), accompanied by a marked increase in lactate dehydrogenase and alanine transferase release. Hypoxic reperfusion caused a significant decrease in hepatocyte and SLC trypan blue uptake. CONCLUSIONS: Fatty livers demonstrate impaired hepatocyte and SLC function, after even a very brief preservation. With increasing preservation, hepatocytes appear to be more susceptible to injury than SLCs. Reoxygenation appears to be important in triggering this event.

Fasting insulin and uric acid levels but not indices of iron metabolism are independent predictors of non-alcoholic fatty liver disease. A case-control study.

BACKGROUND: Non-alcoholic fatty liver disease is a common reason for hepatological consultation and may herald severe hepatic and extra-hepatic disease. The aetiopathogenesis of this condition is an area of increasing interest. AIM: To evaluate anthropometric and biochemical factors associated to non-alcoholic fatty liver disease in a case-control study. Methods. Demographic and biochemical data of 60 consecutive patients with bright liver absent-to-low alcohol consumption, no evidence of viral, genetic and autoimmune diseases, were compared to those of 60 age- and gender-matched historical controls without fatty liver by univariate and multiple logistic regression analysis. RESULTS: Patients were more often hypertriglyceridaemic, obese and diabetic than controls (p<.01). Mean values of alanine transaminase, gammaglutamyltranspeptidase, triglycerides, uric acid, fasting and log insulin, transferrin percent saturation and ferritin were significantly higher in the patients, while transferrin and quantitative insulin sensitivity check index, a quantitative insulin sensitivity index, were lower. No iron storage was found in those who underwent liver biopsy At univariate analysis the relative risk for non-alcoholic fatty liver disease significantly increased (p<0. 05) with increasing body mass index, fasting insulin, alanine transaminase, uric acid, triglycerides and gammaglutamyltranspeptidase; it decreased with increasing transferrin and quantitative insulin sensitivity check index. Multiple logistic regression analysis disclosed only fasting insulin and uric acid to be independent predictors of non-alcoholic fatty liver disease (p<0.05). CONCLUSIONS: Fasting insulin and serum uric acid levels indicating insulin resistance, but not indices of iron overload, are independent predictors of non-alcoholic fatty liver disease.

Safety limit of the extent of hepatectomy for rats with moderately fatty liver: experimental study concerning living liver donor safety.

INTRODUCTION: The aim of the present study was to determine whether rats with moderately fatty liver could withstand a 90% hepatectomy, which rats with normal livers can survive. MATERIAL AND METHODS: Nine-week-old male Wistar rats were used. Normal rat chow was fed to the normal liver group, and fat-enriched rat chow was fed to the fatty liver group for 4 weeks to induce a moderately fatty liver. The authors have previously reported that this fatty liver rat model can cause fatal liver dysfunction after reduced-size-liver transplantation. A 90% and 95% hepatectomy were performed using rats of both groups to evaluate posthepatectomized liver function. RESULTS: All rats undergoing a 90% hepatectomy were still alive 30 days after the hepatectomy, but the rats that underwent a 95% hepatectomy were all dead within 4 days regardless of group. Increases in the liver remnant wet weight measured until 7 postoperative days after 90% hepatectomy were almost similar among the two groups. Alanin aminotransferase measured at 24, 48, 72, and 168 h after a 90% hepatectomy were significantly higher in the fatty liver group than in the normal liver group. Similarly, at up to 72 h postoperatively, the serum hyarulonic acids were significantly higher in the fatty liver group. CONCLUSION: A moderately fatty liver did not cause mortality in 90% hepatectomized rats. However, it caused a higher degree of hepatic parenchymal as well as sinusoidal injury.

Polyene fatty acid interactions with recombinant intestinal and liver fatty acid-binding proteins. Spectroscopic studies.

Binding and proximity relationships of fatty acids with recombinant rat liver fatty acid-binding protein (L-FABP) and intestinal fatty acid-binding protein (I-FABP) were studied with absorption and fluorescence spectroscopy. Protein aromatic amino acids were examined in the absence and presence of bound fatty acid. Second derivative absorbance spectroscopy of the apo- and holoproteins suggested that fatty acid binding altered the conformation of L-FABP, but not of I-FABP. Fatty acid binding also blocked the accessibility of L-FABP tyrosine and I-FABP tryptophan to Stern-Volmer quenching by acrylamide, indicating that these amino acids were present in the fatty acid-binding pocket. Forster energy transfer from I-FABP tryptophan to bound cis-parinaric acid resulted in quenching of tryptophan lifetime and appearance of sensitized lifetime of bound cis-parinaric acid. The calculated donor-acceptor distances were 16.9 +/- 0.6 and 19.2 +/- 0.3 A for I-FABP and L-FABP, respectively. Absorbance spectral shifts and ratios of fluorescence excitation maxima indicated that the parinaric acid microenvironment in the fatty acid-binding site of I-FABP was much less polar than that of L-FABP. Parinaric acids displayed similar rotational correlation time and limiting anisotropy when bound to I-FABP and to L-FABP. These results are consistent with a close proximity of bound fatty acids to the tyrosine and tryptophan residues and with immobilization of the polyene fatty acids in the fatty acid-binding site(s) of L-FABP and I-FABP. The two proteins differ in that only L-FABP has two fatty acid-binding sites and appears to undergo significant conformational change upon fatty acid binding.

Acute fatty liver of pregnancy.

Acute fatty liver of pregnancy (AFLP) is rare and is peculiar to the latter half of pregnancy. Despite the high rates of death among affected mothers and their fetuses, early recognition of the disease and immediate delivery of the infant may improve the chances of survival. This paper describes a case of AFLP, characterized by a rapid decrease in the size of the liver, a greatly prolonged prothrombin time and minimal increases in the serum transaminase levels, in which an immediate cesarean section followed by vigorous supportive care led to survival of both mother and infant. It is clear that guidelines on treatment are necessary if the management of such cases is to be successful.

Acute fatty liver of pregnancy.

Acute fatty liver of pregnancy can produce a great variety of complications. Of these, infections are important. We describe two cases, one of them complicated with uterine sepsis. Both gave evidence of the necessity for multidisciplinary treatment, which reduces the maternal-fetal morbidity and mortality produced by this disease.

Control of adenine nucleotide metabolism in hepatic mitochondria from rats with ethanol-induced fatty liver.

Male rats developed fatty liver after being fed on an ethanol-containing diet for 31 days. Liver mitochondria from these animals catalysed ATP synthesis at a slower rate when compared with mitochondria from pair-fed control rats (control mitochondria), and demonstrated lowered respiratory control with succinate as substrate, owing to a decrease in the State-3 respiratory rate. Respiration in the presence of uncoupler was comparable in mitochondria from both groups of rats. Translocation of both ATP and ADP was decreased in mitochondria from ethanol-fed rats, with ADP uptake being lowered more dramatically by ethanol feeding. Parameters influencing adenine nucleotide translocation were investigated in mitochondria from ethanol-fed rats. Experiments performed suggested that lowered adenine nucleotide translocation in these mitochondria is not the result of inhibition of the translocase by either long-chain acyl-CoA derivatives or unesterified fatty acids. Analysis of endogenous adenine nucleotides in these mitochondria revealed lowered ATP concentrations, but no decrease in total adenine nucleotides. In experiments where the endogenous ATP in these mitochondria was shifted to higher concentrations by incubation with oxidizable substrates or defatted bovine serum albumin, the rate of ADP translocation was increased, with a linear correlation being observed between endogenous ATP concentrations and the rate of ADP translocation. The depressed ATP concentration in mitochondria from ethanol-fed rats suggests that the ATP synthetase complex is replenishing endogenous ATP at a slower rate. The lowered ATPase activity of the ATP synthetase observed in submitochondrial particles from ethanol-fed animals suggests a decrease in the function of the synthetase complex. A decrease in the rate of ATP synthesis in mitochondria from ethanol-fed rats is sufficient to explain the decreased ADP translocation and State-3 respiration.

Prevalence of fatty liver in non-obese Japanese children with atopic dermatitis.

Fatty liver in non-obese Japanese children was observed in 3.2% of non-atopic children and in 17.6% of patients with atopic dermatitis in 2000. The prevalence of fatty liver in non-obese children aged 0-12 years was studied from 2001 to 2003. Subjects were either non-atopic children, or suffering from bronchial asthma, allergic rhinitis, or atopic dermatitis. Fatty liver was studied by abdominal ultrasound scans. The prevalence of fatty liver was increasing annually, and it reached to 12.5% in non-atopic children, 13.1% in patients with bronchial asthma, 13.7% in patients with allergic rhinitis, or 33.9% in patients with atopic dermatitis, in 2003. Since fatty liver in childhood may be a risk factor for lifestyle-related diseases in future, care should be taken to prevent it.

Leptin, free leptin index, insulin resistance and liver fibrosis in children with non-alcoholic fatty liver disease.

OBJECTIVE: Prevalence of non-alcoholic fatty liver disease (NAFLD) among children is increasing dramatically. It is unclear why some patients develop steatohepatitis (NASH), fibrosis and cirrhosis from steatosis, and others do not. A role for leptin has been claimed. This study aims to evaluate the relationship between leptin, insulin resistance (IR) and NAFLD in children. DESIGN AND METHODS: In 72 biopsy-proven NAFLD children (aged 9-18 years; 51M/21F), fasting leptin and its soluble receptor (sOB-R) were measured; free leptin index (FLI) was calculated as leptin/sOB-R; IR was estimated by homeostasis model assessment (HOMA-IR) and insulin sensitivity index (ISI-comp); glucose tolerance by oral glucose tolerance test (OGTT). Percentage of total body fat (TBF) by dual-energy X-ray absorptiometry (DXA) was available in 65 patients. RESULTS: Prevalence of diabetes, impaired fasting and/or after load glucose tolerance was 11%. HOMA-IR and ISI-comp values were 2.55 +/- 1.39 and 4.4 +/- 2. NASH was diagnosed in 38 and simple steatosis in 25 children; diagnosis was indeterminate in 29 children. Increased fibrosis, mostly of mild severity, was observed in 41 patients. Median NAFLD activity (NAS) score was 3.42 +/- 1.60. According to histology, levels of leptin and FLI increased as steatosis (leptin from 11.9 +/- 6.3 in score 1 to 17.4 +/- 6.9 in score 2 (P = 0.01) and 22.2 +/- 6.8 ng/ml in score 3 (P < 0.001); FLI 2.56 +/- 1.40, 3.57 +/- 0.34, 4.45 +/- 0.64 respectively (P = 0.05)); ballooning (from 13.7 +/- 6.7 in score 1 to 17 +/- 7.5 in score 2 (P = 0.001) and 22.1 +/- 7.1 ng/ml in score 3 (P = 0.01); FLI 2.81 +/- 1.50, 3.40 +/- 1.65, 4.57 +/- 1.67 (P = 0.01 between 0 and 2)); fibrosis (from 14.3 +/- 7 to18.3 +/- 6.9; P = 0.03; FLI 3.03 +/- 1.57 vs 3.92 +/- 077; P < 0.05) and NAS score (score 1-2: 12.9 +/- 6.9; score 3-4: 17 +/- 6.9 (P = 0.01); score 5-7: 22.9 +/- 7.5 ng/ml (P = 0.03); FLI 2.70 +/- 1.53, 3.12 +/- 1.53, 4.58 +/- 1.57 P = 0.01 and P = 0.05 between 1-2 vs 3-4 and 3-4 vs 5-7 respectively) worsened. Higher leptin correlated with more severe steatosis, ballooning and NAS score (r(0) = 0.6, 0.4 and 0.6 respectively; for all P < 0.001); FLI with ballooning (r(0) = 0.4, P < 0.0001), steatosis (r(0) = 0.5, P < 0.0001) and NAS score (r(0) = 0.5, P < 0.0001). CONCLUSIONS: Leptin and liver injury correlated independently of age, BMI and gender in the present study. Nevertheless, any causative role of leptin in NAFLD progression could be established. Thus, studies are needed to define whether the hormone plays a major role in the disease.

In vivo magnetic resonance (MR) study of fatty liver: importance of intracellular ultrastructural alteration for MR tissue parameters change.

Fatty liver is thought to have a shorter T1 relaxation time than normal liver tissue, due to the accumulation of triglyceride. Previous studies regarding T1 and T2 relaxation times, however, show widely different results. In order to elucidate the mechanism responsible for the changes and diversity of relaxation times in fatty liver, we created two animal models in 14 rabbits, one acute form (N = 6) and the other chronic form (N = 8). Four rabbits were taken as a control group. Tissue relaxation times and the magnetization transfer (MT) effect of the liver tissue in these two models were measured. The results were correlated with biochemical analysis of water and fat content and histological examination, including findings in light microscopy and electron microscopy. Although the fatty ratio in both forms of fatty liver was similar, their tissue relaxation rate and MT effect were significantly different. The acute form showed prolongation of both T1 and T2 relaxation times (512 +/- 51 msec vs. 710 +/- 95 msec and 39 +/- 1.8 msec vs. 48 +/- 3.7 msec, respectively) and a decrease of the MT effect (50 +/- 5.1% vs. 38 +/- 6.3%), compared to those of the control group and preinduction liver. The chronic form showed shorter T1 and T2 values (526 +/- 36 msec vs. 406 +/- 56 msec and 36 +/- 1.6 msec vs. 33 +/- 2.3 msec, respectively) and a stronger MT effect (21 +/- 0.9% vs. 26 +/- 2.3%). In acute form fatty liver, electron microscopic examination revealed dramatic subcellular changes, such as vesicular transformation, a markedly increased amount of smooth endoplasmic reticulum (SER), and disruption of the crista. These changes were not found in the chronic form fatty liver. From this study, we concluded that the ultrastructural alteration in the subcellular organelles of hepatocyte might play a crucial role for the chameleonic presentation of MR tissue parameters in fatty liver.

Acute fatty liver of pregnancy: a report of two cases.

Acute fatty liver of pregnancy is an uncommon, potentially fatal disorder. Between 1998 and 2000, two patients with acute fatty liver of pregnancy presented at the Christian Medical College Hospital, Vellore. Both patients were in the thirty-sixth week of pregnancy. jaundice and encephalopathy were the predominant symptoms. Both the mothers died after they delivered a stillborn Infant each. The maternal deaths were due to multiorgan failure and/or postpartum haemorrhage and sepsis. The route of delivery was vaginal in both the patients. Extrahepatic and metabolic complications in both cases Included renal failure, sepsis, hypoglycaemia, disseminated intravascular coagulation and gastrointestinal bleeding. Liver biopsy done in both patients was consistent with the diagnosis of acute fatty liver of pregnancy. To the best of our knowledge, this is the first report from India on acute fatty liver of pregnancy.

Dual-energy CT in the diagnosis and quantification of fatty liver: limited clinical value in comparison to ultrasound scan and single-energy CT, with special reference to iron overload.

BACKGROUND/AIMS: It has been suggested that dual-energy CT could differentiate irregular fatty liver from other hypodense lesions. We compared dual-energy CT to ultrasound scan and single-energy CT in the diagnosis and quantification of fatty liver, with special reference to iron overload. METHODS: Twenty-seven patients were included according to ultrasound: fatty liver (n=16) and normal liver (n=11). Single and dual-energy CT were performed. Attenuation measurements of hepatic lobes and control tissues were taken at 140 kV and 80 kV CT-guided liver biopsy was done in fatty liver patients, the degree of infiltration was estimated, and the histologic iron overload determined (iron overload, n=11; iron-free, n=5). RESULTS: The mean changes in attenuation for the right hepatic lobe were: normal liver: -0.8 (ns); iron overloaded fatty liver: 1.5 (ns); and iron-free fatty liver: 7.7 (p<0.0053). A spleen-liver attenuation differential threshold of 12H (140 kV, single-energy CT) and a right hepatic lobe 140 kV to 80 kV attenuation differential threshold of 9 H (dual-energy CT) were specific for fatty liver. Histology confirmed all cases of fatty liver diagnosed by ultrasound, independently of iron overload. Ultrasound did not differentiate cases of irregular from diffuse fatty liver detected on CT. Iron overload produced a masking effect in CT, decreasing its sensitivity: fatty liver was diagnosed in 67% of cases by single-energy CT and in 20% by dual-energy CT. Degree of fatty infiltration correlated with single-energy CT. CONCLUSIONS: Ultrasound diagnosed fatty liver best. Single-energy CT quantifies fatty infiltration, and best differentiates the irregular from the diffuse forms. Dual-energy CT is limited by poor sensitivity, especially in iron overload.

Biliary excretion of enterokinase in rats: studies in alcoholic rats with fatty liver.

Ethanol-associated fatty liver was induced in rats fed a nutritionally deficient liquid diet containing 36% of total calories as ethanol. Control rats received the same diet with sucrose substituted isocalorically for ethanol. After 40 days, hepatic lipid content of the ethanol-maintained animals was four-fold greater than controls and ultrastructural changes in hepatocytes were well established. Clearance of intravenously administered human enterokinase from the circulation as well as bile flow were, however, the same in both groups. The proportion of enterokinase appearing in catalytically active form in bile after intravenous injection was substantially greater in the ethanol-maintained animals than the isocaloric controls; the difference was highly significant (p less than 0.001) and reached two- to four-fold after 70 days on the diet. These findings would suggest that the ability of hepatocytes to degrade enterokinase cleared from the blood may be bypassed or impaired by prolonged ethanol consumption and a deficient diet. Catalytically active enterokinase in bile may participate in the development of some types of acute necrotising pancreatitis.

Factors associated or related to with pathological severity of nonalcoholic fatty liver disease.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) has been more and more often regarded as a serious disorder, because nonalcoholic steatohepatitis (NASH), a part of NAFLD, may progress to the end stage of liver disease. Though an advanced age, obesity, diabetes mellitus (DM) etc. being not infrequent conditions in Korea, are known to exacerbate the severity of this disease, there are only a few Korean reports on this subject. The purpose of this study is to identify possible factors that might add up to the pathological severity of this disorder in Korean patients. METHODS: Of 60 patients with steatosis found at liver biopsy, 43 NAFLD patients were reviewed retrospectively after exclusion of other liver diseases. RESULTS: The cases of steatosis were mild, moderate, and severe in 9. 10, and 24 patients, respectively. The degree of necroinflammatory activity was mild, moderate, and severe in 33, 9, and 1 patients, respectively. There were no established factors directly related to these classes. As to fibrosis, the cases were classified as none, mild, moderate, severe, and cirrhotic in 9, 11, 16, 7, and 0 patients, respectively. The stage of fibrosis correlated with the age (p < 0.001), BMI (body mass index) (p = 0.032), and the platelet count (p = 0.009), but the presence of NASH was associated only with BMI (p = 0.002) and obesity (p = 0.001). CONCLUSION: It seems that there are no factors that are directly related to the degree of steatosis or necroinflammatory activity. BMI seems to be a unique factor directly related to both the severity of fibrosis and the presence of NASH. The age and the platelet count are factors that are directly related to the degree of fibrosis but not to the presence of NASH.

[The prevalence of metabolic syndrome in patients with nonalcoholic fatty liver disease].

BACKGROUND/AIMS: Nonalcoholic fatty liver disease (NAFLD) is associated with dyslipidemia, obesity, and insulin resistance, which are the main features of metabolic syndrome. First, we examined the prevalence of metabolic syndrome among patients with NAFLD. We then compared the prevalence of metabolic syndrome in simple steatosis with that in nonalcoholic steatohepatitis (NASH). Finally, we sought to identify clinical factors associated with the stage of liver fibrosis. METHODS: From November 2002 to March 2004, we enrolled consecutive 25 patients with NAFLD from patients visiting outpatient clinic. The 17 controls were healthy persons who visited our health promotion center. We compared the clinical and biochemical data of the NAFLD group with those of the control group. Using histologic findings, we divided NAFLD into simple steatosis and NASH. We then compared the clinical and biochemical data of the simple steatosis group with those of the NASH group. RESULTS: Fourteen patients (14/25, 56%) had metabolic syndrome in the NAFLD group. There was no difference in the prevalence of metabolic syndrome between the simple steatosis (5/10, 50%) and the NASH group (9/15, 60%). We found significant differences in cardiovascular risk factors between the two groups, but homeostasis model assessment insulin resistance was the only significantly different factor between the simple steatosis group and the NASH group. In addition, no difference in histological features was found between NASH with metabolic syndrome and without metabolic syndrome. CONCLUSIONS: A considerable number of patients with NAFLD had metabolic syndrome. There was a close correlation between NAFLD and metabolic syndrome. We could not find any cardiovascular risk factors that could predict a severe fibrosis.
