Insulin Resistance and Chronic Hepatitis C: Relationship With Serum Iron and Hepcidin.

Backgrounds and aim Besides the clinical evidence supporting insulin resistance in chronic hepatitis C (CHC) patients, the exact mechanism elucidating insulin resistance is still under discussion. The present study aimed to observe any relationship between serum hepcidin, serum iron, and insulin resistance in CHC patients. Methodology A total of 54 individuals were recruited in this study, assorted into group A (CHC population with diabetes) and control group B (CHC population without diabetes). Both groups were tested for serum hepcidin, iron, ferritin, and serum glycemic indices (fasting blood glucose, serum insulin, and insulin resistance). Serum parameters were compared between diabetic and non-diabetic CHC patients by using the Mann-Whitney U test. Correlation analysis was done between serum hepcidin and serum iron, serum hepcidin, and insulin resistance, and serum iron and insulin resistance by applying the Spearman correlation test. Results Diabetic and non-diabetic CHC populations exhibited an iron profile of chronic illness, i.e., low serum iron and hepcidin along with normal ferritin levels. Also, the diabetic and non-diabetic CHC population exhibited normal serum insulin and insulin resistance. However, the fasting serum glucose of the diabetic CHC population was higher than normal. Correlation analysis indicated a negative significant correlation (rho=-0.404, p=0.036) between serum iron and insulin resistance among the diabetic CHC population. Conclusion Our study could not provide any mounting evidence in favor of insulin resistance in the chronic hepatitis C population via serum iron or hepcidin. Hepatitis C virus causing diabetes mellitus may have some etiology other than iron metabolism.
