Abstract
Diabetes is frequently found in patients with chronic HCV infection even before the development of advanced liver disease. The underlying mechanism responsible for derange-ments in glucose tolerance is poorly understood.
Aim of Study: To detect the presence of anti-islet cell antibodies in hepatitis C virus infected patients and also measure insulin resistance in them, which are highly predictive for the development of type 2 DM and which may occur years before the development of manifest diabetes.
Patients and Methods: This study was conducted on 80 chronic hepatitis C patients, excluding patients co-infected with hepatitis B and patients with type 1 diabetes. All patients subjected to full clnical examination, routine chemical labs, abdominal ultrasound, child classification, islet antibodies testing, fasting insulin and HOMA-R calculation.
Results: This study showed very low prevalence of islet cell antibodies in HCV infected patients (3.74%, 3 out of 80), with no correlation between these antibodies and diabetes or insulin resistance. On the contrary insulin resistance had a very high prevalence among the patients (HOMA-R >2.5, in 80%). Insulin resistance was significantly correlated to ad-vanced age, male sex, and presence of liver cirrhosis. A significant negative correlation was also detected between mean value of insulin resistance and serum creatinine values.
Conclusions: Islet cell antibodies does not appear to paly a significant role in the pathophysiology of diabetes in HCV infected patients.
