Approach to patients with hypophosphataemia

Area of Science:

• Biochemistry
• Endocrinology
• Nephrology

Background:

• Phosphate metabolism research is advancing, with expanded knowledge of homeostasis disturbances and new targeted therapies.
• Hypophosphataemia (low serum phosphate) is a biochemical finding in various diseases, necessitating a focus on underlying pathophysiological mechanisms.
• Clinical effects of hypophosphataemia are widespread, impacting multiple organ systems and varying with the primary disorder.

Purpose of the Study:

• To provide a comprehensive review of hypophosphataemia assessment and management.
• To elucidate the pathophysiological mechanisms driving low serum phosphate concentrations.
• To present an updated overview of current and emerging therapeutic strategies.

Main Methods:

• Review of current literature on phosphate metabolism and hypophosphataemia.
• Development of an assessment algorithm for patients with low serum phosphate.
• Analysis of pathophysiological mechanisms and differential diagnoses.
• Evaluation of the latest targeted therapies for hypophosphataemia.

Main Results:

• Established an algorithm for systematic patient assessment.
• Detailed the diverse causes and clinical manifestations of hypophosphataemia.
• Summarized the current landscape of therapeutic interventions.
• Highlighted areas for future research in phosphate metabolism.

Conclusions:

• Understanding pathophysiological mechanisms is crucial for diagnosing hypophosphataemia.
• A structured approach and knowledge of new therapies improve patient management.
• Ongoing research promises enhanced understanding and treatment of phosphate imbalances.
