Paricalcitol, a new Vit. D analogue is thought to be more potent than Calcitriol and has also been reported to cause less hypercalcemia. We report one‐year follow‐up on patients (N = 74) from one inner city dialysis unit. Patients were stratified in groups A, B, C, D depending on intact Paratharmone (iPTH) levels i.e., < 100, 100–300, 300–600, > 600 respectively. Serum Ca, PO4, alkaline phosphatase (ALK), albumin (ALB), hemoglobin (Hb) was measured monthly and serum iPTH was checked quarterly. The results are as follows: Group # PTH Ca PO4 ZPR Hb EPO pg/dl mg/dl mg/dl mcg/hd g/dl U/kg/hd A656.83*9.745.32011.72255.8†B22197.01**9.045.532.48¶12.12137.55C29422.89**9.45.734.54¶¶11.86128.87D171253.4**9.887.2112.51¶¶12.174.35†† PTH: p < 0.05 = *vs**, ZPR(zemplar): p < 0.05¶ vs¶¶, mcg: microgram EPO(erythropoietin): p < 0.05 = † vs††, Mean age, weight, URR, ALB., ALK. and iron indices were not statistically different in all groups. Mean duration of hemodialysis (HD) was 34, 30, 57 & 65 months in groups A, B, C, D respectively. None of these patients had symptomatic bone disease. Seven patients were changed to low Ca (1.0 meq/L) bath secondary to hypercalcemia (Ca > 11.5) & severe hyperparathyroidism (HPT). This data suggest that severe HPT is frequent despite aggressive Paricalcitol therapy in the inner city HD population. More effective noncalcium phosphate binders and/or calcimimetic agents may be needed in addition to dietary and medication compliance in group D to control severe HPT. Interestingly patients with low PTH (< 100) showed relative epogen resistance while patients in group D required smaller epogen doses. There was inverse relationship between ZPR & EPO dosage. The effect of ZPR on EPO responsiveness needs to be confirmed in larger study.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
