Vitamin D supplements in chronic kidney disease

Area of Science:

• Nephrology
• Endocrinology
• Public Health

Background:

• Chronic kidney disease (CKD) affects millions globally, with Vitamin D deficiency being a common comorbidity.
• Vitamin D deficiency in CKD is linked to mineral and bone disorders, cardiovascular issues, infections, and worsening kidney function.
• Emerging research suggests potential benefits of Vitamin D supplementation for CKD patients.

Purpose of the Study:

• To review the current evidence on the effectiveness of Vitamin D supplements in managing CKD.
• To discuss the controversies and ongoing debates surrounding Vitamin D supplementation in clinical practice for CKD.
• To summarize the impact of Vitamin D on CKD-mineral bone disease, renal function, cardiovascular events, and the immune system.

Main Methods:

• Comprehensive literature review of existing laboratory and clinical evidence.
• Analysis of in vitro, animal, and epidemiological studies.
• Synthesis of data concerning Vitamin D's effects on various CKD-related parameters.

Main Results:

• Vitamin D deficiency is prevalent in CKD patients and associated with adverse outcomes.
• Evidence suggests Vitamin D supplements may offer benefits for CKD-mineral bone disease and potentially slow disease progression.
• Significant controversies and ongoing disputes exist regarding the optimal use and efficacy of Vitamin D in CKD.

Conclusions:

• Vitamin D plays a crucial role in CKD management, impacting bone metabolism, cardiovascular health, and immune function.
• While promising, the clinical application of Vitamin D supplements in CKD requires further investigation to resolve existing controversies.
• Continued research, including experimental and clinical studies, is essential to clarify the role of Vitamin D in improving outcomes for individuals with chronic kidney disease.
