Characterization of Medication Trends for Chronic Kidney Disease: Mineral and Bone Disorder Treatment Using Electronic Health Record-Based Common Data Model.

ABSTRACT: Chronic kidney disease-mineral bone disorder (CKD-MBD) is the most common complication in CKD patients. Although there is a consensus on treatment guidelines for CKD-MBD, it remains uncertain whether these treatment recommendations reflect actual practice. Therefore, the aim of this study was to investigate the CKD-MBD medication trend in real-world practice. This was a retrospective and observational study using a 12-year period database transformed into a common data model from three tertiary university hospitals. Study populations were subjects initially diagnosed as CKD. The date of diagnosis was designated as the index date. New patients were categorized year to year from 2008 to 2019 with a fixed observation period of 365 days to check the prescription of CKD-MBD medications including calcium-containing phosphate binder, noncalcium-containing phosphate binder, aluminium hydroxide, vitamin D receptor activator (VDRA), and cinacalcet. The numbers of CKD patients in the three hospitals were 7555, 2424, and 5351, respectively. The proportion for patients with CKD-MBD medication prescription decreased yearly regardless of hospital and CKD stage (p for trend < 0.05). The use of aluminium hydroxide disappeared steadily while the use of VDRA increased annually in all settings. Despite these changes in prescription patterns, the mean value for CKD-MBD-related serologic markers was almost within target range. The proportion of the population within the target value was not significantly changed. Irrespective of hospital and CKD stage, similar trends of prescription for CKD-MBD medications were observed in real-world practice. Further research with a distributed network study may be helpful to understand medication trends in CKD-MBD treatment.

Project description:BackgroundChronic kidney disease-mineral and bone disorder (CKD-MBD) in dogs is associated with hypovitaminosis D, increased parathyroid hormone (PTH), and increased fibroblast growth factor-23 (FGF-23) concentrations. Best practice for vitamin D metabolite supplementation in CKD-MBD remains unknown.ObjectiveTo provide an extended-release calcifediol supplement to dogs with CKD and to measure its effects on variables indicative of CKD-MBD.AnimalsTen dogs with International Renal Interest Society stages 2 and 3 CKD.MethodsIn a prospective study, dogs received a calcifediol supplement for 84 days. Serum 25-hydroxyvitamin D (25[OH]D), 1,25-dihydroxyvitamin D (1,25[OH]2 D), 24,25-dihydroxyvitamin D (24,25[OH]2 D), creatinine, calcium, phosphorus, PTH, plasma FGF-23 concentrations, and urine profiles were measured monthly during supplementation. Urine calcium to creatinine (UCa/Cr) ratios and fractional excretion of calcium, phosphorus, and sodium were determined.ResultsAll serum vitamin D metabolite concentrations increased significantly by day 84 (P < .001): [25(OH)D (median 249.9 ng/mL; range, 149.7-469.9 ng/mL) compared to baseline (median 50.2 ng/mL; range, 31.3-66.0 ng/mL); 1,25(OH)2 D (median 66.1 pg/mL; range, 56.9-88.1 pg/mL) compared to baseline (median 37.3 pg/mL; range, 29.3-56.7 pg/mL); 24,25(OH)2 D (median 81.4 ng/mL; range, 22.1-151.7 ng/mL) compared to baseline (median 15.4 ng/mL; range, 6.9-40.6 ng/mL)]. There were no significant differences in calcium, phosphorus, PTH concentrations, UCa/Cr or fractional excretion of calcium. No dog developed ionized hypercalcemia. Plasma FGF-23 concentrations increased by day 84 (median 1219 pg/mL; range, 229-8824 pg/mL) compared to baseline (median 798 pg/mL; range, 103-4.145 pg/mL) (P < .01).Conclusions and clinical importanceCalcifediol supplementation for 84 days was well-tolerated in dogs with IRIS stages 2 and 3 CKD. It remains to be determined how long-term supplementation would affect CKD progression and QOL.
