Summary
Pompe disease, a rare genetic disorder, was diagnosed in a five-month-old infant presenting with severe hypotonia and heart failure. Muscle biopsy confirmed significant glycogen buildup, leading to the final diagnosis.
Area of Science:
- Pediatrics
- Genetics
- Metabolic Disorders
Background:
- Pompe disease is a rare, inherited metabolic disorder caused by acid alpha-glucosidase deficiency.
- This deficiency leads to progressive accumulation of glycogen in lysosomes, particularly affecting cardiac and skeletal muscle.
Observation:
- A five-month-old infant presented with severe hypotonicity, hyporeflexia, and congestive heart failure.
- Electrocardiogram (ECG) revealed a short PR interval.
- Chest radiography showed marked cardiomegaly, and echocardiography demonstrated significant left ventricular hypertrophy.
Findings:
- Skeletal muscle biopsy was crucial for diagnosis, revealing substantial glycogen accumulation.
- Histopathological examination confirmed the characteristic findings of Pompe disease.
Implications:
- Early diagnosis of Pompe disease is critical for timely intervention and management.
- This case highlights the importance of recognizing cardiac manifestations in infantile Pompe disease.
- Understanding the typical clinical and diagnostic findings aids in prompt identification and treatment strategies.
