Stål and Wahlin group

Metabolic and Inflammatory Liver Disease (MILES)

We study epidemiological and pathophysiological aspects of various metabolic and inflammatory liver diseases, including non-alcoholic fatty liver disease (NAFLD), autoimmune hepatitis (AIH), hereditary hemochromatosis (HH), porphyric liver disease, hepatitis C (HCV) and hepatocellular carcinoma (HCC).

Using big cohorts of patients with a very long follow-up and well characterized clinical data, we combine our findings with data from national registries and tissue analyses. We perform systematic biobanking of liver tissue, DNA and serum, and have unique possibilities to study long-term prognosis, morbidity, mortality and pathogenetic mechanisms of these liver diseases. We look end points such as survival, co-morbidity, or development of cirrhosis and/or hepatocellular carcinoma.

In collaboration with others, we use histology, immunohistochemistry, and molecular biology for translational studies. Our prospective studies aim at finding risk factors for fibrosis progression and for liver cancer development.

Loa Davidsdottir, PhD student
Hannes Hagström, MD, PhD 
Hannes received his MD degree from Karolinska Institutet in 2007 and is a specialist in gastroenterologist and gepatologist. He defended his thesis "The importance of fat and alcohol for progression and prognosis in chronic liver disease" in 2016. Current projects include epidemiology of NAFLD and other liver diseases, aspects of liver immunology and clinical trials. 

Rolf Hultcrantz, Professor, +46 (0)70-484 1433
Research in gastroenterology and hepatology focuses on diseases that affect the stomach, intestines and liver. The field covers many common diseases including gallstones, inflammatory bowel disease, colon cancer, liver diseases such as hepatitis C, alcoholic liver disease and "stomach ache" in general.

Catarina Lindqvist, PhD student 

Catarina received her RD degree from Uppsala University in 2008. She is a clinical dietitian at the department of Clinical Nutrition and Dietetics at Karolinska University Hospital.  She is working with patients suffering from chronic liver diseases and undergoing liver transplantation at the liver center. Her main research focus during her PhD studies is nutritional assessment, body composition and nutrition impact symptoms in patients with chronic liver disease.

Magnus received his MD degree from Karolinska Institute in 2005 and is a specialist in internal medicine and gastroenterology and hepatology since 2015. He is currently working as a gastroenterologist at Karolinska University Hospital mainly in the field of Hepatology.

Knut Stokkeland, MD, PhD
Knut Stokkeland received his MD degree in 1990 from The University of Bergen. He works as a Senior Consultant at the Department of Medicine at Visby Hospital.  In 2006, His PhD theses was  Studies on alcoholic liver disease. His research focus after the PhD has been on the epidemiology of alcoholic liver disease, the effect on children born of women with alcoholic liver disease and other chronic liver diseases. His main current research focus is on the effects of alcohol on patients with who have undergone liver transplants and on patients with esophageal varices and on medication that may reduce liver fibrosis. He collaborates with collegues at Capio S:t Goran, Sahlgrenska University Hospital and several Departments at the Karolinska Institutet.
