 This study investigated the relationship between ghrelin levels and various biochemical and demographic indices in a group of non-diabetic hemodialysis patients. The results showed that there was no significant correlation between ghrelin levels and age, dialysis quality, dosage, calcium level, ALP, PTH, vitamin D and hemoglobin in these patients. Further research is needed to better understand the role of ghrelin in hemodialysis patients. This article was authored by Leila Mamudnia, Sarah by Griziai, Muhammad Reza Tamadon and others.
