Background: Erythropoietin (EPO) has been used clinically for the treatment of anemia as it was the first characterized hematopoietic factor. Erythropoietin is produced primarily by the kidneys (renal cortical fibroblasts) which induces proliferation and differentiation of erythroid progenitor cells. Previous studies suggested that erythropoietin may directly stimulates the regeneration of damaged tubular cells due to presence of erythropoietin receptors on renal tubular epithelial, mesangial and endothelial cells. EPO directly prevent glomerulosclerosis as a consequence of amelioration of podocyte injury. Therefore, to improve kidney function in chronic kidney disease (CKD), it is of critical importance to investigate clinically the beneficial reno-protective effects of EPO in patients with CKD.
Methodology: The study was conducted at King Abdulaziz Medical City and included patients with chronic kidney diseases. Patients were under medical treatment with Darpeboetin for the first time. The administration frequency of Darpeboetin was single dose weekly. Kidney function tests including serum creatinine, serum urea, alkaline phosphatase, serum calcium, serum phosphorus, serum albumin and albuminuria were collected from the hospital electronic medical record system (BestCareR). Test values before and after treatment were compared. of the patients before starting treatment and at the end of treatment. The week before starting treatment was considered week 0 (baseline)
Results: The results indicated that, treatment with a weekly single dose of Darpeboetin reduces blood urea nitrogen (BUN p=0.002) and serum uric acid level (p=0.009). The effect of treatment on serum calcium and potassium, showed a significant elevation of serum potassium (P<0.001), serum calcium (P<0.001) and adjusted calcium (P<0.001) levels parallel with significant decrease in serum phosphorus (p=0.004). Also treatment of chronic kidney disease patients significantly ameliorates serum albumin (P<0.001).
Conclusion: Treatment with Darpeboetin may confirm the reno-protective potency. Darpeboetin is a promising drug to prevent or attenuate tissues kidney damage especially in chronic kidney disease
