Article Abstract
Objectives: This study was designed to evaluate the impact of fructose-rich diet and chronic kidney disease (CKD) on the in vitro function of pancreatic islets.
Methods: Fifty-four rats were divided into 3 equal groups as follows: control, rats with CKD 1/2 that underwent surgical uninephrectomy, and rats with CKD 5/6 that underwent uninephrectomy and kidney cortex mass resection. Each group was further assigned to 3 diet protocols--regular diet, regular diet with 10% fructose (F10), and 60% fructose-rich diet (F60). After 8 weeks of insulin administration, C-peptide, glycated hemoglobin level, serum urea nitrogen, creatinine clearance, and homeostasis model assessment of insulin resistance were evaluated. Static glucose insulin stimulation test of isolated pancreatic islets and histologic analysis of pancreatic tissue were performed.
Results: The F10 diet increased the levels of insulin and C-peptide in all groups. Homeostasis model assessment of insulin resistance was increased in all animals fed with fructose. The elevated levels of creatinine and diminished creatinine clearance were detected in CKD 5/6 rats fed with 60% fructose-rich diet. The F10 diet resulted in high levels of serum insulin and C-peptide and glucose-stimulated insulin secretion. Fructose-rich diet increased the islet size and number, with irregular morphology and exocrine tissue fibrosis.
Conclusions: The fructose-rich diet accelerates the progression of CKD and affects the pancreatic islet function.
