Leadership in a Private Nephrology Practice: Autonomy Is More Than a Dream!

Private practice is entering an era of diminishing reimbursement and increasing overhead associated with federally mandated payment reforms resulting in a need to move from the traditional fee-for-service to a value-based model, changes that place financial and organizational strain on nephrology practices. In addition, the changing geopolitical scene is one of mergers and consolidation of health care networks, which in turn are developing their own insurance plans or partnering with commercial payers. The new landscape will require the leadership of a private nephrology practice to vigilantly monitor and adapt to these changes for success. Our leaders must be mindful of the impact of these changes to foster the successful growth of an autonomous private nephrology practice in which there is opportunity for personal and professional growth of its members in their quest to provide quality and safe patient care

Iron Replacement Therapy with Oral Ferric Maltol: Review of the Evidence and Expert Opinion

Iron deficiency is the most common cause of anemia globally and is frequently reported in patients with underlying inflammatory conditions, such as inflammatory bowel disease (IBD) and chronic kidney disease (CKD). Ferric maltol is a new oral iron replacement therapy designed to optimize iron absorption while reducing the gastrointestinal adverse events associated with unabsorbed free iron. Ferric maltol has been studied in clinical trials involving almost 750 adults and adolescents with iron-deficiency anemia associated with IBD, CKD, and other underlying conditions, and it has been widely used in clinical practice. It is approved for the treatment of adults with iron deficiency with or without anemia, independent of the underlying condition, and is commercially available in Europe and the United States. We review the published evidence for ferric maltol, which demonstrates consistent and clinically meaningful improvements in hemoglobin and measures of iron availability (ferritin and transferrin saturation) and shows that it is well-tolerated over long-term treatment for up to 64 weeks—an important consideration in patients with chronic underlying conditions such as IBD and CKD. We believe that ferric maltol is an effective, convenient, and well-tolerated treatment option for iron deficiency and iron-deficiency anemia, especially when long-term management of chronic iron deficiency is required.

A Prospective Cohort Study of Mineral Metabolism After Kidney Transplantation.

BACKGROUND: Kidney transplantation corrects or improves many complications of chronic kidney disease, but its impact on disordered mineral metabolism is incompletely understood. METHODS: We performed a multicenter, prospective, observational cohort study of 246 kidney transplant recipients in the United States to investigate the evolution of mineral metabolism from pretransplant through the first year after transplantation. Participants were enrolled into 2 strata defined by their pretransplant levels of parathyroid hormone (PTH), low PTH (\u3e65 to ≤300 pg/mL; n = 112), and high PTH (\u3e300 pg/mL; n = 134) and underwent repeated, longitudinal testing for mineral metabolites. RESULTS: The prevalence of posttransplant, persistent hyperparathyroidism (PTH \u3e65 pg/mL) was 89.5%, 86.8%, 83.1%, and 86.2%, at months 3, 6, 9, and 12, respectively, among participants who remained untreated with cinacalcet, vitamin D sterols, or parathyroidectomy. The results did not differ across the low and high PTH strata, and rates of persistent hyperparathyroidism remained higher than 40% when defined using a higher PTH threshold greater than 130 pg/mL. Rates of hypercalcemia peaked at 48% at week 8 in the high PTH stratum and then steadily decreased through month 12. Rates of hypophosphatemia ( CONCLUSIONS: Persistent hyperparathyroidism is common after kidney transplantation. Further studies should determine if persistent hyperparathyroidism or its treatment influences long-term posttransplantation clinical outcomes.This is an open-access article distributed under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 3.0 License, where it is permissible to download and share the work provided it is properly cited.

Randomized Controlled Trial of Difelikefalin for Chronic Pruritus in Hemodialysis Patients

INTRODUCTION: There is an unmet medical need for pruritus associated with chronic kidney disease, a distressing complication characterized by generalized and persistent itch affecting 20% to 40% of patients undergoing hemodialysis. Here we report the results of a phase 2 trial evaluating the efficacy and safety of a novel peripherally restricted kappa opioid receptor agonist, difelikefalin, in adult patients undergoing hemodialysis with pruritus. METHODS: In this study, 174 hemodialysis patients with moderate-to-severe pruritus were randomly assigned to receive difelikefalin (0.5, 1.0, or 1.5 μg/kg) or placebo intravenously thrice weekly after each hemodialysis session for 8 weeks in a double-blind, controlled trial. The primary endpoint was the change from baseline at week 8 in the weekly mean of the 24-hour Worst Itching Intensity Numerical Rating Scale score. The secondary efficacy endpoint was the change in itch-related quality of life measured by the Skindex-10 questionnaire. Other endpoints included safety, sleep quality, and additional measures including the 5-D itch scale. RESULTS: A significant reduction from baseline in itch intensity scores at week 8 favored all difelikefalin doses combined versus placebo ( CONCLUSION: In this trial, difelikefalin effectively reduced itching intensity and improved sleep and itch-related quality of life
