Approximately 10-20% of patients with non-alcoholic fatty liver disease (NAFLD) are at risk of progressing to cirrhosis. The cause of such progression is unclear. SEN-V is a hepatotropic virus that has been associated with more severe and advanced liver disease in patients with chronic hepatitis C virus infections.
M. Grubert Van Iderstine et al. (section of Hepatology, Department of Medicine, University of Manitoba, Winnipeg, Manitoba, Canada) tested 32 NAFLD patients for evidence of SEN-V infection and correlated the results with histologic findings. Their study revealed similar disease severity and stage of progression in SEN-V positive and negative patients.
Other non-A-E hepatotropic viruses may contribute to the development and course of NAFLD, as discussed in this study.
