Improvement of dysphagia in a child affected by Pompe disease treated with enzyme replacement therapy

Insights

Enzyme replacement therapy (ERT) improved dysphagia in a Pompe disease patient. Videofluoroscopic Swallowing Study confirmed normal swallowing after 36 months of ERT.

Area of Science:

  • Biochemistry
  • Neurology
  • Genetics

Background:

  • Pompe disease (PD) is a rare metabolic myopathy caused by alpha-glucosidase deficiency.
  • Dysphagia is a common complication in PD, significantly impacting patient quality of life.
  • Enzyme replacement therapy (ERT) with alglucosidase alfa is the standard treatment for PD, but its effect on dysphagia is unknown.

Observation:

  • A 6-year-old boy with PD presented with severe oral stage dysphagia (Grade 1).
  • The patient received ERT with alglucosidase alfa for 36 months.
  • Videofluoroscopic Swallowing Study (VFSS) was used to assess swallowing function at baseline and after treatment.

Findings:

  • Baseline VFSS revealed complete incoordination of oral swallowing, graded as DSS Grade 1.
  • After 36 months of ERT, VFSS showed normal swallowing function, graded as DSS Grade 0.
  • ERT demonstrated a significant positive impact on swallowing ability in this PD patient.

Implications:

  • ERT may be an effective treatment for dysphagia in Pompe disease patients.
  • VFSS is a valuable diagnostic and monitoring tool for swallowing disorders in PD.
  • Further research is warranted to confirm these findings in a larger cohort.

Esophageal Achalasia01:27

Esophageal Achalasia

Esophageal achalasia is a chronic neurogenic disorder characterized by impaired relaxation of the lower esophageal sphincter (LES) and absent or ineffective peristalsis in the distal esophagus. This leads to a functional obstruction without a physical blockage, despite significant disruption of esophageal motility.EtiologyAchalasia is caused by degeneration of the myenteric (Auerbach's) plexus, specifically the loss of inhibitory ganglion cells that produce vasoactive intestinal peptide (VIP)...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Esophageal Strictures-II: Clinical Features and Management

Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Gastroesophageal Reflux Disease II: Clinical Features and Management

Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...
Esophageal Strictures-I: Introduction01:30

Esophageal Strictures-I: Introduction

Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...
