The Viral Hepatitis Research Group

Denna sida på svenska

The group study how hepatitis viruses cause disease and how the body reacts to the infection, and the factors that contribute to the cure and/or control of the disease.

We focus both on basic research but also development of new therapies. The group has several national and international cooperations in both academia and in the pharmaceutical industry. The translational research is conducted in collaboration with the Unit for Infectious Diseases, Karolinska University Hospital Huddinge and Linköping University Hospital.

Viral hepatitis is a major health problem with approximately half a billion people infected world-wide. The viruses that primarily causes liver inflammation are hepatitis A, B, C, D and E. The infection is characterized by mild to severe disease, including jaundice, fever, myalgia, nausea, fatigue, vomiting, fatty liver, cirrhosis, liver failure and liver cancer. Hepatitis viruses can be divided into two groups depending on how the virus is transmitted between individuals. Hepatitis A and E are transmitted by the fecal-oral route (eg. ingestion of contaminated water and food) and hepatitis B, C and D are mainly transmitted parenterally (eg. infected blood). Prevention is available by prophylactic vaccines for hepatitis A, B and D, but not for hepatitis C and E. Antiviral treatments are available for hepatitis B, C and D, but with varying responses depending on the type of infecting virus.
