Comparison of erythropoietin resistance in hemodialysis patients using calcitriol, cinacalcet, or paricalcitol.
The erythropoiesis-stimulating agent (ESA) hyporesponsiveness index (EHRI) calculated as the weekly dose of EPO divided by weight (kg) divided by hemoglobin level (g/dL) has been considered useful to assess ESA resistance. Recent evidence suggests that active vitamin D, cinacalcet, and paricalcitol use may be related with lower ESA resistance. We conducted this observational cross-sectional study to investigate ESA resistance calculated by the EHRI among patients using calcitriol, cinacalcet, and paricalcitol. Participants underwent a medical history taken, physical examination, measurement of biochemical analysis, calculation of dialysis adequacy, and EHRI. Sixty-five patients did not receive any treatment regarding vitamin D, paricalcitol, and cinacalcet (group 1), 41 were taking only vitamin D (group 2), 50 were taking only paricalcitol (group 3), 19 were taking only cinacalcet (group 4), and 21 were taking paricalcitol + cinacalcet (group 5). The EHRI values for groups 1, 2, 3, 4, and 5 were 11.36 ± 8.72, 11.58 ± 5.72, 8.29 ± 5.54, 9.49 ± 4.61, and 8.91 ± 4.44 respectively (P =.034). Post hoc analysis showed that the EHRI differed between group 1 and group 3 (P =.017) and between group 2 and group 3 (P =.006). In linear regression analysis, use of paricalcitol was independently associated with EHRI. In conclusion, paricalcitol use was associated with lower EHRI levels as a measure of ESA resistance.

Cholecalciferol supplementation in hemodialysis patients: effects on mineral metabolism, inflammation, and cardiac dimension parameters.
Vitamin D deficiency is highly prevalent in chronic kidney disease. The aim of this study was to evaluate the effects of oral cholecalciferol supplementation on mineral metabolism, inflammation, and cardiac dimension parameters in long-term hemodialysis (HD) patients.. This 1-year prospective study included 158 HD patients. Serum levels of 25-hydroxyvitamin D [25(OH)D], 1,25-dihydroxyvitamin D [1,25(OH)(2)D], intact parathyroid hormone, and plasma brain natriuretic peptide as well as circulating bone metabolism and inflammation parameters were measured before and after supplementation. Baseline 25(OH)D and 1,25(OH)(2)D levels were measured twice (end of winter and of summer, respectively). Therapy with paricalcitol, sevelamer, and darbepoietin was evaluated.. There was an increase in serum 25(OH)D and 1,25(OH)(2)D levels after supplementation. Conversely, serum calcium, phosphorus, and intact parathyroid hormone were decreased. There was a reduction in the dosage and in the number of patients who were treated with paricalcitol and sevelamer. Darbepoietin use was also reduced, with no modification of hemoglobin values. Serum albumin increased and C-reactive protein decreased during the study. Brain natriuretic peptide levels and left ventricular mass index were significantly reduced at the end of the supplementation.. Oral cholecalciferol supplementation in HD patients seems to be an easy and cost-effective therapeutic measure. It allows reduction of vitamin D deficiency, better control of mineral metabolism with less use of active vitamin D, attenuation of inflammation, reduced dosing of erythropoiesis-stimulating agents, and possibly improvement of cardiac dysfunction.

Severe hyperparathyroidism despite paricalcitol therapy: one-year follow-up.
Paricalcitol [Zemplar: Abbott Laboratories, Abbott Park, IL, U.S.A.] is efficient for treating secondary hyperparathyroidism in patients on maintenance hemodialysis (HD). Zemplar is thought to be more potent than calcitriol and has been reported to cause less hypercalcemia and hyperphosphatemia. Here, we report a 1-year follow-up on patients from one inner-city dialysis unit. We reviewed the charts of 100 patients and collected data for 1 year. Patients were stratified into four groups depending upon their intact parathormone (iPTH) levels. Hemoglobin (Hb) and erythropoietin (EPO) doses were determined. More than 50% of patients had iPTH levels greater than 300 pg/mL. Mean Ca and PO4 levels were not significantly different, but Zemplar doses were significantly different in all groups. None of the patients had symptomatic bone disease. Seven patients were changed to low-Ca dialysate (1.0 mEq/L) secondary to hypercalcemia (Ca > 11.5 mg/dL) and severe secondary hyperparathyroidism. Interestingly, patients with low iPTH (< 100 pg/microL) showed relative EPO resistance, and patients with high iPTH (> 600 pg/microL) required smaller EPO doses. An inverse relationship was observed between Zemplar and EPO dose. The effect of Zemplar on EPO responsiveness needs to be confirmed in a larger study. Our data suggest that severe secondary hyperparathyroidism is frequent despite aggressive paricalcitol therapy in our inner-city HD population. To control severe secondary hyperparathyroidism in these patients, dietary and medication compliance may need to be supplemented with more effective non-calcium phosphate binders or calcimimetic agents, or both.
