Insights
Chronic kidney disease-mineral bone disorder (CKD-MBD) management has evolved beyond parathyroid hormone (PTH) control. A multidisciplinary approach and new treatments aim to improve cardiovascular and survival outcomes in CKD patients.
Area of Science:
- Nephrology
- Endocrinology
- Internal Medicine
Background:
- Chronic kidney disease (CKD) is linked to significant morbidity and mortality.
- Disturbances in mineral metabolism are major contributors to mortality in CKD patients.
- CKD-mineral bone disorder (CKD-MBD) is a systemic condition involving bone, mineral, and vascular abnormalities.
Purpose of the Study:
- To review the current therapeutic strategies for CKD-MBD.
- To discuss the latest advancements in treatments for CKD-MBD.
- To highlight the shift towards improved cardiovascular and survival outcomes in CKD-MBD management.
Main Methods:
- Review of current literature on CKD-MBD treatments.
- Analysis of new therapeutic agents including phosphate binders, vitamin D derivatives, and calcimimetics.
- Emphasis on the role of a multidisciplinary approach in patient management.
Main Results:
- Current treatments focus on managing CKD-MBD beyond just parathyroid hormone (PTH) control.
- New therapeutic agents offer improved management options for mineral metabolism disturbances.
- A multidisciplinary approach involving nurses, dieticians, and clinicians enhances patient outcomes.
Conclusions:
- CKD-MBD requires a comprehensive management strategy.
- Novel treatments and a multidisciplinary approach are crucial for improving cardiovascular and survival outcomes in CKD patients.
- The focus has shifted from managing renal osteodystrophy to a broader CKD-MBD paradigm.
Abstract:
Chronic kidney disease (CKD) is associated with increased morbidity and mortality. Mineral metabolism disturbances appear to contribute to the high mortality rate. A CKD-mineral bone disorder (CKD-MBD) has recently been defined as a systemic disorder manifested by one or a combination of abnormalities in bone biopsy, laboratory parameters and/or vascular or other soft-tissue calcifications. New available treatments have contributed to move from the former treatment paradigm of renal osteodystrophy to CKD-MBD management, beyond mere control of parathyroid hormone (PTH) and trying to improve cardiovascular or survival outcomes. Thus, the recommended multidisciplinary approach among nurses, dieticians and clinicians, helping not only through dietary assessment but also through education, behaviour control and by increasing the patient's personal motivation, may have additional important benefits. This article will review the current therapeutic approach with phosphate binders including the latest developments, vitamin D derivatives and selective vitamin D receptor activators as well as the new calcimimetics, all used in the treatment of this systemic disease.
