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.

-Background -Protein-calorie malnutrition is a frequent fi nding in patients with chronic liver disease, but investigations of nutritional status have been rarely performed in individuals seen at outpatient clinics. Aim -To evaluate the nutritional status of patients with alcoholic and nonalcoholic cirrhosis, attended for the fi rst time at a reference outpatient clinic for liver diseases. Patients and methods -A total of 300 consecutive patients attended at the outpatient clinics of a reference center for liver diseases were investigated. Anthropometric evaluation was performed by the usual parameters: triceps skinfold, arm circumference and arm muscle circumference. Biochemical parameters included creatinine/height index, serum albumin and lymphocytes count. The nutritional diagnosis was based on the PCM score proposed by Mendenhall et al. Food intake was retrospectively evaluated using 24-hour dietary recall data. Results -About 71% of the patients studied were chronic alcohol abusers, whereas in 29% cirrhosis was of nonalcoholic etiology. Independently of the disease etiology 75.3% of the patients showed some degree of protein-calorie malnutrition, which was moderate or severe in 38.3% of them. More advanced protein-calorie malnutrition degrees were associated with lower energy and protein intake. The prevalence of moderate or severe protein-calorie malnutrition was higher in patients classifi ed as Child-Pugh C than in patients classifi ed as Child-Pugh A (21% x 58%, respectively). Regarding sexual differences, fat reserves, evaluated by triceps skinfold, were more depleted in females than in males (48.6% x 26.6%) regardless of the etiology of the cirrhosis, whereas muscle reserves (arm muscle circumference) were more depleted in males (43.4% x 13.4%) regardless of the etiology of cirrhosis. In contrast, cirrhosis of alcoholic etiology was determinant in reducing arm muscle circumference in females (20% x 9.1%).Conclusions -These data highlight the high prevalence of protein-calorie malnutrition occurring early in the natural history of the disease and accompanying functional hepatic deterioration. In addition, attention should be paid to the different gender patterns of response to protein-calorie malnutrition in these patients. HEADINGS -Nutritional status. Liver cirrhosis. Outpatients.

Nutritional intervention as exclusive treatment, with a loss of at least 5% of initial weight, is effective in the treatment of non-alcoholic fatty liver disease.

-In order to draw evidence-based recommendations concerning the management of autoimmune diseases of the liver, the Brazilian Society of Hepatology has sponsored a single-topic meeting in October 18th, 2014 at São Paulo. An organizing committee comprised of seven investigators was previously elected by the Governing Board to organize the scientific agenda as well as to select twenty panelists to make a systematic review of the literature and to present topics related to the diagnosis and treatment of autoimmune hepatitis, primary sclerosing cholangitis, primary biliary cirrhosis and their overlap syndromes. After the meeting, all panelists gathered together for the discussion of the topics and the elaboration of those recommendations. The text was subsequently submitted for suggestions and approval of all members of the Brazilian Society of Hepatology through its homepage. The present paper is the final version of the reviewed manuscript organized in topics, followed by the recommendations of the Brazilian Society of Hepatology.

Serum HA was the parameter that alone presented the best diagnostic accuracy in the assessment of hepatic fibrosis in CHC. The APRI showed a better diagnostic sensitivity than GGT levels or the AST/ALT ratio. Its simple determination and low cost make this index a valid alternative for the noninvasive staging of CHC.

The prevalence of obesity-related metabolic syndrome has rapidly increased in Brazil, resulting in a high frequency of nonalcoholic fatty liver disease, that didn't receive much attention in the past. However, it has received increased attention since this disease was identified to progress to end-stage liver diseases, such as cirrhosis and hepatocellular carcinoma. Clinical practice guidelines for the diagnosis and treatment of nonalcoholic fatty liver disease have not been established in Brazil. The Brazilian Society of Hepatology held an event with specialists' members from all over Brazil with the purpose of producing guideline for Nonalcoholic Fatty Liver Disease based on a systematic approach that reflects evidence-based medicine and expert opinions. The guideline discussed the following subjects: 1-Concepts and recommendations; 2-Diagnosis; 3-Non-medical treatment; 4-Medical treatment; 5-Pediatrics - Diagnosis; 6-Pediatrics - Non-medical treatment; 7-Pediatrics - Medical treatment; 8-Surgical treatment.

Hepatic fibrosis in patients with non-alcoholic fatty liver disease is associated with progression of the disease. In the present study, we analyzed the discriminative ability of serum laminin, type IV collagen and hyaluronan levels to predict the presence of fibrosis in these patients. In this preliminary report, we studied 30 overweight patients divided into two groups according to the absence (group I, N = 19) or presence (group II, N = 11) of fibrosis in a liver biopsy. Triglycerides, aspartate aminotransferase, alanine aminotransferase, gamma-glutamyltranspeptidade, hyaluronan (noncompetitive fluoroassay), type IV collagen, and laminin (ELISA) were determined. Group II presented significantly higher mean laminin, hyaluronan, type IV collagen, and aspartate aminotransferase values, which were due to the correlation between these parameters and the stage of fibrosis in the biopsy (Spearman's correlation coefficient, rS = 0.65, 0.62, 0.53, and 0.49, respectively). Analysis of the ROC curve showed that laminin values >282 ng/ml were those with the best diagnostic performance, with 87% accuracy. Association of laminin with type IV collagen showed improvement in the positive predictive value (100%), but with reduction in diagnostic sensitivity (64%). When compared with the criteria of Ratziu et al. [Gastroenterology (2000) 118: 1117-1123] for the diagnosis of septal fibrosis, laminin values presented a better diagnostic accuracy (83 vs 70%). Determination of extracellular matrix components in serum, especially of laminin, may identify patients with non-alcoholic fatty liver disease and fibrosis and these components may be used as indicators for liver biopsy in these patients
