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.

Iron overload in chronically HCV-infected patients was uncommon and hepatic iron content seemed not to be related to the liver damage process. In the eventuality of iron overload, histochemical liver iron is a useful marker to estimate HIC.

The prevalence of steatosis in hepatitis C was high. Risk factors usually related to steatosis such as age, female gender and obesity, as well as genotype 3, were independently associated with the presence of steatosis. Steatosis was not independently associated with the intensity of histological liver disease.
