About

Insulin resistance is one of the key factors in defining a progressive course of chronic Hepatitis C virus (HCV) infection and hepatic fibrosis. Multiple trials have targeted insulin resistance as an adjuvant way to manage hepatitis C liver disease with promising results.

Long term therapy using high dose insulin was shown to significantly reduce insulin resistance in obese patients. In cardiac and critically ill patients, long term insulin was shown to produce better outcomes mainly by reducing the overt inflammatory response. Furthermore, initial results of ongoing trials are revealing more benefits of insulin therapy. Using the (hyperinsulinimic normoglycemic clamp) for eight hours on patients undergoing major liver resection was able to maximize their liver function post-operatively. This trial also demonstrated inhibition of the inflammatory response, improvement in liver glycogen, inhibition of apoptosis and stimulation of liver regeneration.

Putting in mind the potential ability of the liver to regenerate and regain better function. The anti-inflammatory properties of insulin therapy along with its ability to reduce insulin resistance over time has led us to see the potential benefits of using insulin therapy on patients with chronic hepatitis C virus liver cirrhosis. Insulin will target the pathophysiology of the disease at a cellular and a molecular level.

The investigators theorize that long-term high insulin therapy would be able to promote better liver function and slow down fibrosis and injury in this population of patients.
