Diabetes Metab ; In a study on the prevention of diabetes, fenformin was well tolerated in a wide group of insulin-resistant obese patients, and significantly reduced the incidence of established diabetes Insulin resistance and hyperinsulinemia in patients with thalassemia maior treated by hypertransfusion.

On the other hand, although hepatic steatosis generally carries a benign prognosis and can be diagnosed by clinical, laboratory, and ultrasound esteatohepatitks, it can progress to NASH and cirrhosis; therefore, patients whose data are suggestive of disease progression should be selected and entered into treatment protocols. Although histological assessment is the golden rule for identifying NASH, there is no widespread agreement in regard to its evaluation, although Brunt modified semiquantitative staging 83which classifies inflammatory activity into grades 0 to 3 and fibrosis into stages 0 to 4, is the most widely used system Table II.

Scand J Gastroenterol ; Hyperferritinemia, iron overload, and multiple metabolic alterations identify patients at risk for nonalcoholic steatohepatitis. Betaine is a choline metabolite that increases S-adenosylmethionine levels, protects the liver from triglyceride deposits and oxidative stress in mice fed with alcohol, and may therefore have some efficacy as an antioxidant in NAFLD Insulin resistance plays a fundamental role in type-2 diabetes mellitus, as well as in obesity, and is the most predisposing and reproducible factor in NASH 24 Table I.

Although most cases of NASH are detected in the fifth and sixth decades of life, it should be emphasized that the prevalence of this disease is increasing in children 67,68 ; it can therefore present at any age.

Some mutations of the encoding gene for these nuclear receptors have been identified in esteaohepatitis with NASH, and might be involved in its pathogenesis Clin Perspect Gastroenterol Leptin is considered to contribute to the appearance of steatosis and NASH by promoting insulin resistance, altering hepatocyte insulin signaling, promoting fatty acid synthesis, and increasing proinflammatory responses; however, it could be beneficial in lipodystrophic patients with NAFLD, since the administration of leptin to lipodystrophic mice that had developed secondary leptin deficiency, associated with insulin resistance and steatosis, led to their healing A hypothesis has recently been put forward that fat cells may play a central role in the development of insulin resistance, as well as of NASH.

Most patients with primary iron overload unrelated to hemochromatosis have insulin resistancewhich may improve with phlebotomy 55, Similarly, many patients with cryptogenic cirrhosis may develop NASH with a loss of the peculiar histological characteristics of this condition 14, The preliminary results of treatment with atorvastatin are promising esteafohepatitis indicate that 3-hydroxy-3methylglutaryl-coenzyme A reductase inhibitors may be useful in the treatment of NASH The natural history of nonalcoholic steatohepatitis: It has been suggested that leptin may be classified as a cytokine as it does not only regulate food intake and energy consumption, but also modulates immune and inflammatory responses This factor is normally found synthesized and maintained in an inactive form within the cell cytoplasm, bound to the IKK protein.

Factors that may imply a higher risk of steatosis developing to NASH include: The fact that there is no universal effective treatment for NASH leads some to avoid invasive diagnostic tests such allcoholica liver biopsy. The greater afflux of fatty acids to the liver, together with the potential alterations of its metabolization within the liver including esteahohepatitis triglyceride synthesis, reduced triglyceride elimination, and reduced beta-oxidation of fatty acidsresults in hepatic steatosis; these mechanisms are considered a “first impact’ in the development of NASH.

A possible beneficial effect of metronidazole in reducing TPN-associated liver function derangements. Many factors can contribute to NASH-related mortality, including the complications of obesity and diabetes.

Molecular mechanisms of insulin-stimulated glucose uptake in adipocytes. Angulo P, Lindr KD. Semin Liver Dis ; It must be underscored esteatphepatitis severe -even moderate- hepatic steatosis may result in primary graft dysfunction; therefore, grafts with this condition are not acceptable for transplantation. Effect of ursodeoxycholic acid plus diet in patients with non-alcoholic steatohepatitis Abstract. J Pediatr ; Proliferating alcojolica activated receptors PPAR are expressed in tissues with important oxidative phosphorilation, and regulate lipids through the peroxisomal, microsomal, and mitochondrial pathways.

Diabetes is an important independent predictor of severe hepatic fibrosis in Fsteatohepatitis Metformin reverses nonalcoholic fatty liver disease in obese leptin-deficient mice. Bilirubin and albumin usually remain within their normal ranges 7,69,70, The effect of betaina in reversing alcoholic steatosis.

J Gastroenterol Hepatol ; 6: Belfiore F, Iannello S. The causes of recurrence are unknown and may probably be due to multiple factors, including hypertriglyceridemia, obesity, diabetes, and corticoid therapy.

Further insight into the natural history of the disease and prospective therapeutic trials for correct decision-making are warranted AGA technical review on nonalcoholic fatty liver disease.

It is contraindicated for patients with potential lactic acidosis, renal failure, estatohepatitis congestive heart failure.

A pilot study of a thiazolidinedione, troglitazone, in nonalcoholic steatohepatitis. Free fatty acids thus produced are highly miscible with cell membranes, so that they immediately go to fat cells where they are converted into resterified triglycerides, or to the muscle as energy supply, or enter the liver.
