Cardiomyopathy in propionic acidaemia
1Medical Unit, Institute of Child Health, London, United Kingdom.
Insights
Propionic acidaemia can cause cardiomyopathy, a serious heart condition. This study found cardiomyopathy in 6 of 19 patients, with some cases being fatal, highlighting the need for awareness.
Area of Science:
- Biochemistry
- Cardiology
- Genetics
Background:
- Propionic acidaemia is an inherited metabolic disorder.
- Cardiomyopathy is a potential complication of propionic acidaemia.
Observation:
- A review of 19 patients with propionic acidaemia identified 6 with cardiomyopathy.
- Three of these patients died, while three experienced complete resolution of cardiac disease.
Findings:
- Cardiomyopathy is a significant and potentially fatal complication in propionic acidaemia.
- Standard therapy and L-carnitine did not demonstrably alter the outcome of cardiomyopathy in this cohort.
Implications:
- Early detection and monitoring for cardiomyopathy are crucial in patients with propionic acidaemia.
- Further research is needed to explore effective treatments for propionic acidaemia-associated cardiomyopathy.
Abstract:
Following the death of a patient with propionic acidaemia with a cardiomyopathy we reviewed 19 patients with the same disorder for evidence of cardiomyopathy. Six patients were found to meet the diagnostic criteria. Three patients died and in the other three the cardiac disease resolved completely. All patients were treated with standard therapy and some received L-carnitine but this did not seem to influence the eventual outcome. Cardiomyopathy is an important complication of propionic acidaemia and may be rapidly fatal.
