Benign elevation of serum alkaline phosphatase, transient and persistent variety

Area of Science:

• Pediatric Endocrinology
• Clinical Biochemistry

Background:

• Elevated serum alkaline phosphatase (AP) is a common finding in pediatric practice.
• Distinguishing benign causes from serious pathology is crucial for appropriate patient management.

Purpose of the Study:

• To investigate the etiology and clinical significance of markedly increased serum alkaline phosphatase (AP) in children.
• To identify familial and transient forms of benign hyperphosphatasemia.

Main Methods:

• Case identification of children with significantly elevated serum AP.
• Comprehensive clinical investigation including family surveys and follow-up studies.
• Analysis of the pattern and origin of hyperphosphatasemia.

Main Results:

• Seven children presented with markedly increased serum AP concentrations.
• In all seven cases, the elevated AP was determined to be a benign finding.
• A familial pattern was observed in four children, while three had a transient, idiopathic origin.

Conclusions:

• Benign forms of hyperphosphatasemia are prevalent in pediatric populations.
• Recognition of familial and transient hyperphosphatasemia aids in accurate interpretation of elevated AP levels.
• Awareness of these benign conditions prevents unnecessary investigations and patient anxiety.
