Abstract
C hronic renal failure (CRF) is a rapidly growing global health problem, with a prevalence of 15% in developed nations. Cognitive impairment has increasingly been recognized in CRF. Studies have shown impairment in executive function ranging from 23% - 38% and memory impairment ranging from 28% - 33% in patients with CRF. Anemia is an important risk factor for cognitive impairment in CRF and antianemic drug recombinant human erythropoietin (rHu-Epo) is a standard therapy for the management of anemia in CRF. Experimental studies have also shown that rHu-Epo exerts a remarkable neuroprotection in both cell cultures and in animal models of nervous system disorders. Studies show amyloid precursor protein (APP), β amyloid (Aβ) and hyperphosphorylated tau (pTau) protein expressions are useful biomarkers to detect cognitive dysfunction. In this study, we found that the impact of rHu-Epo supplementation on neurobehavioral changes caused by CRF induction in experimental animals and correlated the same with APP, Aβ and pTau expressions in brain regions such as cerebellum, cerebral cortex and hippocampus of CRF induced animals. Along with this, we also determined haematological parameters and brain creatine kinase activity. CRF was induced in rats by adenine mixed feed (0.75%, w/w) treatment for 4 weeks. Neurobehavioral changes such as learning, memory, reasoning and anxiety-related behaviors were recorded in CRF induced animals using rectangular and pluz maze procedures. Haematological parameters and APP, Aβ, pTau expressions and creatine kinase activity in brain regions were altered in CRF induced animals. Supplementation of rHu-Epo (100 IU/ Kg bwt, thrice a week) in combination with adenine mixed diet treatment or post treatment of rHu-Epo (after 4 weeks of adenine mixed diet treatment), 12 days daily reversed the changes caused by CRF. In this study, the benefits of antianemic drug rHu- Epo against CRF induced neurotoxicity were seen.
