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.
