I have created a place for non-pharmacological treatment of obesity in adults and an ambulance for non-invasive diagnosis of liver diseases. I am the President of the Slovak Society of Practical Obesitology. I attended several study stays abroad, organized 5 interdisciplinary conferences with international participation and I regularly give lectures at domestic and foreign specialized events.

Introduction: Chronic viral hepatitides B and C (CVH-B/CVH-C) are serious medical, public health, social and economic problems globally. In Slovakia chronic liver diseases are the fifth most common cause of death in overall, and third in people of productive age. The European Association for the Study of the Liver rankes Slovakia as the country with the fourth-highest liver diseases mortality, after Hungary, Romania and Slovenia. Material and methods: Screening was conducted for the presence of antibodies to the hepatitis C virus (anti-HCV) in all patients who were sent to our outpatient department (Internal Clinic for Liver Disease Diagnosis and Treatment in Bardejov Spa, Remedium s.r.o.) for the purpose of differential diagnosis of liver diseases between 2010 and 2017. During that period, 3,518 new patients were sent to this clinic. In each patient an ultrasound examination of the abdominal organs and a complete differential diagnosis of liver diseases were performed. When positive antibodies to hepatitis C virus were detected, HCV-RNA was supplemented with the determination of the presence of ribonucleic acid of the hepatitis C virus and the genotype of the hepatitis C virus. A liver investigation was also conducted using transient elastography.Results: Anti-HCV antibodies were found in 53 patients (1.5%). HCV-RNA was detected in 43 patients (1.2%). Of these, 42 (97.7%) were examined using Fibroscan. Heavier damage to the liver (F2-F4) was present in 27 of the 43 patients (62.7%). Before coming to our outpatient clinic 19 of these 27 (70.3%) had never been treated for CVH-C. Conclusions: Chronic viral hepatitis C is currently the only chronic viral infection that can be cured. Therefore, a systematic search for patients with a slight change in liver function tests is warranted. Close interdisciplinary cooperation between general practitioners and specialists is necessary in identifying patients with CVH-C.

Hepatic diseases are the sixth most common cause of death in the European Union. The World Health Organization has adopted a global strategy to eliminate viral hepatitis as a serious public health threat by 2030. Approximately one quarter of patients with CHC (chronic hepatitis C) has developed cirrhosis of the liver. It is a precancerosis with a high risk of developing hepatocellular carcinoma. From an epidemiological point of view, injection drug use (IDU) is the most significant way of transmitting HCV infection. Patients with an increased risk of transmitting HCV infection, active IDUs, homosexuals with risky sexual practices, women planning to conceive, patients undergoing hemodialysis and prisoners should all be treated in preference. This population of patients is threatened by an addiction itself as well as by infections, repeated reinfections or mixed infections, concomitant mental disorders or diseases, and multiple associated disorders. To the fulfilment of the WHO strategy on HCV elimination/eradication would certainly contribute a nationwide screening in individual European countries and active collaboration with general practitioners who could treat patients with HCV by themselves-that is, without help of specialists, with pan-genotypic drugs.
