Introduction And Objective:
Insulin resistance and diabetes mellitus are frequently associated with chronic hepatitis C virus (HCV) infection, and it is thought that the presence of insulin resistance aggravates liver disease. We aimed to evaluate insulin resistance in nondiabetic Egyptian patients with chronic HCV infection.
Materials And Methods:
Sixty nondiabetic patients with chronic HCV infection and 30 healthy nondiabetic non-HCV-infected volunteers were enrolled in our study. They were divided into 3 groups: group 1 included 30 patients with chronic HCV infection with no cirrhosis, group 2 included 30 patients with chronic HCV infection and cirrhosis of the liver, and group 3 included 30 healthy volunteers as controls. The entire study population underwent a detailed clinical history and physical examination, weight and height measurement, routine laboratory tests, and viral marker determination that included hepatitis B surface antigen and HCV antibodies. PCR analysis was carried out on the patients with positive HCV antibodies. Fasting blood sugar and fasting insulin levels were measured in all the patients, and insulin resistance was calculated according to the homeostasis model assessment of insulin resistance (HOMA-IR).
Results:
Patients with cirrhosis of the liver (2 patients with Child class A, 12 patients with Child class B, and 16 patients with Child class C) showed higher insulin resistance levels (2.76±0.97) than the patients with chronic HCV infection and no cirrhosis (2.03±0.743) and the control group (1.22±0.38). The p value was significantly different between the 3 groups. There were direct and significant correlations between insulin resistance, fasting blood sugar, and fasting insulin levels. Patients with chronic HCV infection showed significantly higher fasting insulin and glucose levels than the control group.
Conclusion:
Chronic HCV-infected patients showed significantly higher insulin resistance levels than the normal population, even in the absence of hepatic dysfunction and cirrhosis.
