Insights

Nocturnal acid breakthrough is common in children on proton pump inhibitors for reflux esophagitis. Adding ranitidine did not improve healing, suggesting proton pump inhibitors alone are effective.

Area of Science:

  • Pediatric Gastroenterology
  • Pharmacology
  • Acid Reflux Management

Background:

  • Reflux esophagitis is a common condition in children.
  • Proton pump inhibitors (PPIs) are a standard treatment for pediatric reflux esophagitis.
  • Nocturnal acid breakthrough (NAB) during PPI therapy may impact treatment efficacy.

Purpose of the Study:

  • To determine the incidence of nocturnal acid breakthrough in pediatric patients receiving PPIs for reflux esophagitis.
  • To compare the healing of esophagitis in children with NAB who received PPIs with or without ranitidine.

Main Methods:

  • Prospective, double-blind study involving 18 pediatric patients (ages 1-13).
  • Esophagitis assessed via endoscopic and histologic scores.
  • Esophagogastric pH monitoring performed at week 3 to identify nocturnal acid breakthrough.
  • Patients with NAB were randomized to receive PPIs +/- ranitidine at bedtime.

Main Results:

  • Nocturnal acid breakthrough occurred in 89% of patients.
  • Esophagitis improved in all patients, with mean endoscopic and histologic scores decreasing significantly (P < 0.0020).
  • Symptoms improved significantly (P = 0.0001), but ranitidine supplementation showed no additional benefit.

Conclusions:

  • Nocturnal acid breakthrough is highly prevalent in pediatric patients on PPI therapy.
  • Despite NAB, esophagitis and symptoms improved with PPIs alone.
  • Ranitidine added at bedtime did not provide additional therapeutic benefit for healing or symptom control.

Acid Suppressive Drugs for Peptic Ulcer Disease: Proton Pump Inhibitors

Peptic ulcers, often induced by H. pylori infections or NSAID usage, arise from disruptions in the delicate balance of gastric acid production. Peptic ulcers stem from heightened gastric acid levels due to H. pylori infections or NSAID use. The protective mucus layer diminishes in the presence of these factors, allowing gastric acid to erode the stomach lining and form ulcers.
Gastric acid, a potent cocktail of hydrogen and chloride ions, is produced in specialized parietal cells within the...

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...

Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...

Acid Suppressive Drugs for Peptic Ulcer Disease: Antacids

In the complex environment of the gastric lumen, excessive acid secretion can lead to the formation or worsening of ulcers within the delicate mucosal layer. Antacids, such as sodium bicarbonate and calcium carbonate, provide relief by neutralizing this acid, transforming it into harmless salt and water. This neutralization process raises the gastric pH from a highly acidic level of 1 to a more basic 3-4, reducing the acidity within the stomach.
However, this neutralization reaction between...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Acid Suppressive Drugs for Peptic Ulcer Disease: Histamine H2-Receptor Antagonists

Histamine H2 receptors, which are intricately located on the basolateral membrane of parietal cells, play a crucial role in modulating gastric acid secretion. When released from enterochromaffin-like cells, histamine engages H2 receptors, initiating the cyclic AMP (cAMP) pathway. In this pathway, adenylyl cyclase converts ATP into cAMP, elevating intracellular cAMP levels. The activation of protein kinase A follows, stimulating the proton pump. This stimulation prompts the secretion of hydrogen...
