RESUMEN
The liver is of key importance in the proper functioning of most of endocrine system. It is a major organ for metabolic degradation of many hormones. In chronic liver disease, there is a change in the concentrations of main pancreatic hormones. In this study, we aimed to study pancreatic islet cell hormones in non ascitic non diabetic cirrhotic HCV patients by measuring these hormones basally and after intravenous glucose load with different concentrations to evaluate pattern of endocrine pancreatic hormonal response at increasing glucose concentration. This case-control study included 25 non ascitic non diabetic patients with cirrhosis due to HCV infection; age ranged from 28 to 60 years. They were selected from outpatient clinic of National Hepatology and Tropical Medicine Research Institute [NHTMRI] during June 2004 to January 2005. Fifteen age and sex matched apparently healthy control subjects from same area were also included in study. Assessment of pancreatic islet cell function was done by assaying insulin, C-peptide, somatostatin and glucagon hormones. All hormones were determined by radioimmunoassay [RIA] for both patients and controls. Basal insulin, basal somatostatin and basal glucagons levels were significantly higher than that of controls [p<0.05]. Basal C-peptide was significantly lower than that of controls [p<0.05]. After intravenous glucose load with different concentrations 5%, 10% and 25%, insulin level showed a significant increase than controls [p<0.05], while other hormones showed no significant difference as compared to controls [p>0.05].
