Abstract
Background
The kidney plays a vital role in the metabolism of minerals and bone health. It is not only the target organ of several regulating hormones such as parathormon (PTH) and fibroblast growth factor-23 (FGF-23), but it is also the main organ that activates vitamin D. Calcium and phosphorus are fundamentally important in a wide array of biological functions. Abnormalities in calcium, phosphorus, parathyroid hormone (PTH), and vitamin D metabolism (usually referred to as disordered mineral metabolism) are common in patients with (CKD).
Aim of the work
Comparing the effect of hemodiafiltration (HDF) versus conventional Hemodialysis on bone markers.
Patients and Methods
The study was performed on 50 patients in Ain Shams University Specialized Hospital with end-stage renal failure treated by means of chronic hemodialysis (n = 25) and hemodiafiltration (n = 25). Inclusion criteria were end stage renal disease patients on regular hemodialysis for > 6 months, their age> 18 years old, no recent infection (normal CRP), cardiac or vascular access complication, none of the patients had history of bone disease, fracture or malignancy. As regarding blood transfusion and drug intake (affect bone metabolism or hemostasis) had not administered for 1 month perior to study.
Results
Both groups had lower levels of serum creatinine before and after sessions of HD or HDF but Hemodialysis (HD) patients has higher levels of phosphate and bone ALP, than patients on HDF.
Conclusion
Hemodiafiltration (HDF) has better effect on bone metabolism than Hemodialysis (HD).
