Summary
Hereditary fructose intolerance (HFI) can be diagnosed in adults using medical history and fructose tolerance tests. Many adults with HFI are asymptomatic due to dietary restriction, making diagnosis challenging.
Area of Science:
- Metabolic disorders
- Clinical diagnostics
- Human genetics
Background:
- Hereditary fructose intolerance (HFI) is a rare genetic disorder.
- It affects fructose metabolism, leading to potential toxicity upon ingestion.
- Diagnosis in adults is often delayed or missed.
Observation:
- A 69-year-old male was diagnosed with HFI.
- Diagnosis was confirmed via medical history and intravenous fructose tolerance testing.
- Control subjects of similar age were included for comparison.
Findings:
- Adults with HFI may be asymptomatic due to self-imposed dietary restrictions (fructose and sucrose).
- Diagnosis relies heavily on detailed dietary history.
- The true prevalence of HFI in the adult population is unknown but potentially underestimated.
Implications:
- Highlights the importance of considering HFI in adult patients with unexplained symptoms or dietary histories.
- Suggests current diagnostic approaches may need refinement for adult HFI cases.
- Underscores the need for further research into adult HFI prevalence and presentation.
