Insights
X-linked pyruvate dehydrogenase deficiency in a male infant caused severe neonatal lactic acidosis. A modified ketogenic diet improved compliance and clinical stability, allowing developmental progress.
Area of Science:
- Biochemistry
- Genetics
- Pediatrics
Background:
- Pyruvate dehydrogenase deficiency is an X-linked metabolic disorder.
- Neonatal lactic acidosis is a severe complication.
- The ketogenic diet is a treatment option, but compliance can be challenging.
Observation:
- A male infant presented with severe neonatal lactic acidosis due to X-linked pyruvate dehydrogenase deficiency.
- Initial adherence to a strict ketogenic diet was poor.
- The diet was modified to a less restrictive formulation.
Findings:
- The modified ketogenic diet significantly improved patient compliance.
- The child remained clinically stable one year after dietary modification.
- Developmental progress was observed on the modified diet.
Implications:
- Less restrictive ketogenic diets may improve treatment adherence in pediatric metabolic disorders.
- Dietary modifications can lead to sustained clinical stability and development.
- This case highlights the importance of personalized therapeutic approaches for rare genetic diseases.
Abstract:
A male child with X-linked pyruvate dehydrogenase deficiency presented with severe neonatal lactic acidosis. Poor compliance following initiation of the ketogenic diet justified modification to a less restrictive form which improved compliance. One year after starting the modified diet, he remained clinically stable, showing developmental progress.

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Outcomes of Glycolysis
Cellular respiration can occur aerobically (with oxygen) or anaerobically (without oxygen). In the presence of oxygen, cellular respiration starts with glycolysis and continues with pyruvate oxidation, the...
Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
