Abstract
Chronic kidney disease (CKD) is among the most significant health problems, with
the associated cardiovascular disease and bone metabolism disorders being the leading cause of morbidity
and mortality in these patients. The aim of the study was to determine markers of bone turnover
in patient sera (phosphates, calcium, alkaline phosphatase, parathyroid hormone and osteoprotegerin
(OPG)) in all stages of kidney failure including kidney transplant recipients. We also wanted to determine
whether dialysis vintage affects recovery of bone markers one year after transplantation. There were
164 study patients, whereas 30 healthy individuals served as a control group. Serum OPG progressively
increased with decline of the glomerular filtration rate. The highest OPG concentration was recorded
in dialysis group. We observed a statistically significant OPG increase in stage 2 CKD. In kidney
transplant group, there was positive correlation between OPG and dialysis vintage. We also found that
serum OPG was lower in patients treated with dialysis for less than 4 years prior to transplantation. We
confirmed that CKD-mineral and bone disorder began in stage 3 CKD with parathyroid hormone and
OPG elevation, and a statistically significant OPG increase in stage 2 CKD might be an early sign of
CKD-mineral and bone disorder. Dialysis vintage longer than 4 years is associated with more significant
disturbances in mineral and bone metabolism.
