Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) and Its Relationship with Bone Metabolism
TL;DR
The need for comprehensive strategies to mitigate the systemic effects of CKD-MBD is highlighted, including phosphate control, vitamin D supplementation, and the use of calcimimetics—is essential for enhancing patient outcomes.
Abstract
Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD) is a multifaceted syndrome marked by disturbances in bone and mineral metabolism due to chronic kidney disease (CKD). These disruptions involve imbalances in calcium, phosphate, vitamin D, and parathyroid hormone (PTH) levels, which can result in skeletal deformities, vascular calcification, and heightened cardiovascular risk. This article explores the connection between CKD-MBD and bone metabolism, emphasizing the dynamic processes of bone formation and resorption influenced by both systemic and local factors. It discusses the pathophysiology of CKD-MBD, including changes in vitamin D metabolism and the development of secondary hyperparathyroidism. Additionally, the article outlines clinical manifestations such as fractures and cardiovascular complications, along with advanced diagnostic tools and treatment strategies. Effective management of CKD-MBD—through phosphate control, vitamin D supplementation, and the use of calcimimetics—is essential for enhancing patient outcomes. By examining the interactions between CKD, mineral metabolism, and bone health, this article highlights the need for comprehensive strategies to mitigate the systemic effects of CKD-MBD.
