Abstract
ObjectiveTo investigate the mineral and bone disorder (MBD) in patients with chronic kidney disease (CKD ) at stage G3 to G5.
MethodsA cross-sectional study was carried out in the Ninetl People’s Hospital of Suzhou. From August 2014 to August 2019, 323 inpatients were enrolled. Parameters including serum phosphorus (P), total calcium (t-Ca), intact parathyroid hormone (iPTH) and alkaline phosphatase (AKP) were analyzed. All the patients were divided into three groups (CKD G3 group, CKD G4 group and CKD G5 group ). The parameters of MBD were compared and the abnormal conditions of calcium, phosphorus and iPTH were evaluated.
ResultsIn CKD G3 to G5 patients, serum P was(1.28±0.25), (1.48±0.30) and (2.03±0.62 )mmol/L (F=81.51, P<0.01); the incidence of hyperphosphatemia was 25.56%, 47.95% and 83.75%; serum Ca was(2.34±0.11), (2.26±0.17), and (2.07±0.27)mmol/L (F=51.45, P<0.01); the incidence of hypocalcemia was 2.22%, 9.59% and 41.25%; serum iPTH was(90.82±55.59), (161.63±143.55) and (282.02±162.04)ng/L (F=60.83, P<0.01); the incidence of high parathyroid hormone was 56.67%, 68.49% and 38.13%, respectively. Correlation analysis showed that serum iPTH level was positively correlated with serum phosphate (r=0.32, P<0.01) and negatively correlated with serum calcium (r=-0.43, P<0.01) and glomerular filtration rate (GFR ) (r=-0.52, P<0.01).
ConclusionsFrom the beginning of the CKD G3 stage, serum Ca, P, iPTH began to appear relatively abnormal, and with the progressive decrease of glomerular filtration rate, serum P and iPTH began to gradually increase, and serum Ca gradually decreased. Early monitoring and clinical intervention should be given to improve patients’ outcomes.
