Osteoporosis Risk

AbstractLoss of bone mineral density (BMD) is a substantial risk of mortality in addition to fracture in hemodialysis patients. However, the factors affecting BMD are not fully determined. We conducted a single-center, cross-sectional study on 321 maintenance hemodialysis patients who underwent evaluation of femoral neck BMD using dual-energy X-ray absorptiometry from August 1, 2018, to July 31, 2019. We examined factors associated with osteoporosis defined by T-score of ≤  − 2.5, using logistic regression models. Median age of patients was 66 years, and 131 patients (41%) were diagnosed with osteoporosis. Older age, female, lower body mass index, diabetes mellitus, and higher Kt/V ratios were associated with higher osteoporosis risk. The only medication associated with lower osteoporosis risk was calcium-based phosphate binders (CBPBs) [odds ratio (OR), 0.41; 95% confidence interval (CI), 0.21–0.81]. In particular, CBPB reduced the osteoporosis risk within subgroups with dialysis vintage of ≥ 10 years, albumin level of < 3.5 mg/dL, active vitamin D analog use, and no proton pump inhibitor (PPI) use. In conclusion, CBPB use was associated with lower osteoporosis risk in hemodialysis patients. This effect might be partially attributable to calcium supplementation, given its higher impact in users of active vitamin D analogs or non-users of PPI, which modulate calcium absorption.

Abstract Background and Aims Recently, we demonstrated the efficacy of etelcalcetide for control of secondary hyperparathyroidism (SHPT) in the DUET trial; a 12-week multicenter, open-label, randomized (1:1:1), parallel-group study treated with etelcalcetide + active vitamin D (Group E+D), etelcalcetide + oral calcium preparation (Group E+Ca), or control groups (Group C) in 124 subjects undergoing maintenance hemodialysis. Moreover, we also showed that active vitamin D was useful in correcting hypocalcemia induced by calcimimetics, but the oral calcium preparation was superior for suppression of hyperphosphatemia. In this post hoc analysis, we evaluated vascular calcification markers, fibroblast growth factor 23 (FGF23) and calciprotein particles (CPPs), in patients using etelcalcetide (n = 77) extracted from the registrants of the DUET trial. Method Serum levels of FGF23 and CPPs were measured at baseline, 6 weeks and 12 weeks after start of the trial. Skewed data (FGF23 and CPPs) were transformed to natural logarithm to achieve normal distribution prior to statistical analysis. The changes in log CPPs and log FGF23 were estimated in a linear mixed model with each treatment group, time point, and interaction of the treatment group and time point as the fixed effects. We compared these changes between treatment the groups using a linear mixed model and also the Tukey-Kramer method to correct for multiplicity. Additionally, we exploratory examined the correlations among changes of FGF23, CPPs and other biomarkers related to bone mineral metabolisms, iPTH, Ca, P, and calcium-phosphate product, tested by Spearman’s rank correlation coefficient. Results The decreases at the 12-week time point after the trial start in log FGF23 were estimated -1.13 pg/mL in Group E+Ca and -0.10 pg/mL in Group E+D in a linear mixed model, respectively. Similarly, the decreases in CPPs were estimated -1.60 AU in Group E+Ca and -0.82 AU in Group E+D, respectively. Changes of both FGF23 (P = 0.017) and CPPs (P &lt; 0.001) in Group E+Ca significantly decreased compared with those in in Group E+D by Tukey-Kramer multiple-comparison test at 12 weeks after the trial start, while both changes in CPPs and FGF23 could not reach the significant differences between two groups at 6 weeks after the trial start (Figure 1). Reductions in FGF23 positively correlated with reductions in calcium (ρ = 0.42, P &lt; 0.01) and phosphate (ρ = 0.48, P &lt; 0.01) at 6 weeks after the trial start, and in calcium (ρ = 0.30, P &lt; 0.01) and phosphate (ρ =0.70, P &lt; 0.01) at 12 weeks after 6 weeks of the trial start), but there was no correlation with reductions in iPTH at any time point. Reductions in CPPs positively correlated with reductions only in phosphate at 6 weeks after the trial start (ρ = 0.47, P &lt; 0.01) and at 12 weeks after 6 weeks of the trial start (ρ = 0.54, P &lt; 0.01). Conclusion In this analysis, vascular calcification markers were significantly decreased in Group E+Ca compared to those in Group E+D. Further studies should be needed, our study suggests that oral calcium preparation may have an advantage against vascular calcification rather than active vitamin D for the correction of hypocalcemia induced by etelcalcetide in hemodialysis patients with SHPT.

Objective The objective of this study was to assess the relationship between intact parathyroid hormone levels (iPTH) and hemoglobin (Hb) levels in patients with end-stage renal disease (ESRD) who were on hemodialysis. Material and methods  An observational, cross-sectional study was conducted in the Department of Nephrology at Jinnah Postgraduate Medical Centre in Karachi, Pakistan. Patients were enrolled in this study after consent and institutional review board approval. Serum samples were collected for Hb level, iPTH level, vitamin D, urea and creatinine, ferritin, and transferrin saturation.  Results Ninety four patients were inducted into this study; men comprised 66.0% of the patients, and Diabetes mellitus was the commonest etiology of ESRD. Most of the patients were on dialysis for more than 5 years on twice per week hemodialysis. Mean Hemoglobin was 9.29g/dl, iPTH 576.59ng/dl and Vitamin D 25.47ng/ml. Significant inverse correlation was found between anemia and i-PTH levels. Conclusion Hyperparathyroidism is one of the major contributor anemia among maintenance hemodialysis patients.
