Insights

Gastroesophageal reflux (GER) is common in infants with cystic fibrosis (CF), causing various symptoms. Treating GER with cisapride significantly improved infant health, suggesting anti-reflux therapy is crucial for CF patients.

Area of Science:

  • Pediatrics
  • Gastroenterology
  • Pulmonology

Background:

  • Cystic Fibrosis (CF) often presents with diverse respiratory and gastrointestinal symptoms.
  • Gastroesophageal reflux (GER) is a potential complicating factor in infants with CF.
  • Standard CF treatments may not fully address GER-related complications.

Purpose of the Study:

  • To investigate the prevalence of GER in infants with newly diagnosed CF.
  • To evaluate the efficacy of cisapride, a GI prokinetic agent, in managing GER in CF infants.
  • To assess the impact of GER treatment on clinical manifestations in CF.

Main Methods:

  • pH monitoring over approximately 20 hours was used to diagnose GER in ten infants with CF.
  • Eight infants received treatment with the prokinetic drug cisapride.
  • Clinical follow-up studies were conducted to evaluate symptom improvement.

Main Results:

  • All ten infants diagnosed with CF exhibited abnormal GER.
  • Cisapride treatment led to normalized pH monitoring in seven out of eight treated infants.
  • Significant clinical improvement in respiratory, gastrointestinal, and weight gain issues was observed during cisapride therapy.

Conclusions:

  • Abnormal GER is highly prevalent in infants with cystic fibrosis.
  • Cisapride treatment effectively managed GER and improved clinical outcomes in CF infants.
  • Anti-reflux therapy should be considered an integral component of managing young CF patients.

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...

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...
Barrett Esophagus-I: Introduction01:21

Barrett Esophagus-I: Introduction

Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more similar...

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...
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)...
Hiatal Hernia01:25

Hiatal Hernia

A hiatal hernia is the abnormal protrusion of the stomach or other abdominal organs through the esophageal hiatus of the diaphragm into the thoracic cavity.Normally, the gastroesophageal junction (GEJ) lies below the diaphragm and is supported by the phrenoesophageal membrane, the diaphragmatic crura, and connective tissues. Weakening of these structures—due to aging, congenital defects like a short esophagus, or increased intra-abdominal pressure from coughing, obesity, pregnancy, or heavy...
