[Death following fructose and sorbitol infusions]

Area of Science:

• Biochemistry
• Genetics
• Metabolic Disorders

Background:

• Hereditary Fructose Intolerance (HFI) is an autosomal recessive metabolic disorder.
• It results from a deficiency in the enzyme aldolase B, crucial for fructose metabolism.
• The prevalence of HFI is estimated at 1 in 20,000 to 1 in 50,000 live births.

Observation:

• Patients with HFI often present with symptoms only after consuming fructose or sorbitol.
• Infusions containing fructose and sorbitol are widely used in clinical settings.
• Delayed diagnosis is common, frequently occurring in adulthood.

Findings:

• The lack of timely diagnosis in HFI patients leads to prolonged exposure to dietary triggers.
• This exposure can result in severe health complications, including liver damage and hypoglycemia.
• The risks associated with delayed diagnosis of HFI are often underestimated.

Implications:

• Highlights the critical need for increased awareness and earlier screening for HFI, especially in adults.
• Emphasizes the importance of considering HFI in patients presenting with unexplained metabolic derangements.
• Underscores the potential dangers of fructose and sorbitol administration in undiagnosed individuals.
