Liver function tests are among the most determined biochemical parameters, and it is essential that their interpretation is always performed correctly. The presence of liver disease is indicated not only by the well-known basic panel of liver function tests (bilirubin, ALT, AST, GGT and ALP), but also by other biochemical parameters, especially albumin, INR and platelet count. The latter analytes are often overlooked, as is the fact that normal values in the baseline liver test panel do not yet rule out advanced chronic liver disease - liver fibrosis or cirrhosis. In contrast, high levels of liver function tests do not automatically indicate liver failure. Considering the increasing incidence of liver disease as well as the rising mortality from liver causes in many European countries, it is desirable to update the diagnostic algorithm when pathological liver function tests are detected.

Finding an effective treatment of non-alcoholic fatty liver disease (NAFLD) remains one of main challenges in hepatological research for the 21st century, since there is no such a treatment yet. Lifestyle modifications leading to weight reduction are cheap and effective, however only a fraction of patients reaches significant weight loss goals. Current pharmacological treatment of NAFLD comprises screening and therapy of metabolic syndrome components and minimizing of alcohol intake. There are new substances being evaluated in clinical trials, the most promising ones are semaglutide and lanifibranor.

Non-alcoholic fatty liver disease (NAFLD) is currently the most common chronic liver disease in developed countries, where it affects up to a quarter of the population. The groups at most risk are diabetics, obese and patients with dyslipidemia, i. e. individuals with advanced metabolic syndrome, in whom the prevalence of NAFLD exceeds 50 %. Some of these patients develop inflammation, so-called steatohepatitis, and subsequent fibroproduction, which in turn can lead to liver cirrhosis with all the complications, especially liver failure, portal hypertension (ascites, esophageal varices) and hepatocellular carcinoma. Therefore recently great emphasis has been placed on actively searching for advanced forms of NAFLD in this population in order to identify and adequately treat these patients in a timely manner. Today, diagnostic methods are widely available and the development of effective therapies for advanced forms of NAFLD is at the forefront of research interest.

Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease nowadays. It is referred to as liver manifestation of metabolic syndrome. Given the growing incidence of diabetes and obesity, we can confidently say that we will be, or even are facing, a NAFLD pandemic in the near future. Despite strenuous efforts, there is no causal therapy and the only effective therapeutic modality is a complex lifestyle change encompasses diet and regime changes leading to a weight loss. However, it is clear from many published papers that putting these recommendations into practice and their long-term compliance with patients is very difficult. What can be offered to patients with NAFLD in clinical practice and how can they be rationally treated?
