Phosphate homeostasis and disorders

Area of Science:

• Biochemistry and Molecular Biology
• Endocrinology
• Nephrology

Background:

• Phosphate is vital for numerous bodily functions.
• Phosphate balance is regulated by vitamin D, parathyroid hormone, and phosphatonins like fibroblast growth factor-23 (FGF23).
• Disruptions in phosphate homeostasis (hypo- and hyperphosphataemia) are prevalent and have significant clinical implications.

Purpose of the Study:

• To review recent advancements in understanding phosphate homeostasis.
• To detail the causes, diagnostic approaches, and management strategies for hypophosphataemia and hyperphosphataemia.

Main Methods:

• Literature review of recent studies on phosphate metabolism.
• Synthesis of current knowledge on regulatory mechanisms.
• Analysis of clinical consequences and management of phosphate imbalances.

Main Results:

• Hyperphosphataemia is increasingly linked to elevated cardiovascular disease risk.
• Advances in understanding FGF23's role in phosphate regulation.
• Identification of key factors in maintaining phosphate balance.

Conclusions:

• A comprehensive understanding of phosphate metabolism is essential for clinical practice.
• Effective management of phosphate disorders can mitigate associated health risks, including cardiovascular complications.
• Ongoing research continues to refine our knowledge of phosphate homeostasis and its clinical relevance.
