What is the next step in managing a 68-year-old female patient with chronic acid reflux, reactive gastropathy in the antrum, and symptoms of food stuck in the stomach, who has shown improvement with over-the-counter (OTC) antacids but experiences recurring symptoms when not taking them?

Management of Chronic Acid Reflux in a 68-Year-Old Female with Reactive Gastropathy

The most appropriate next step in management for this 68-year-old female with chronic acid reflux and reactive gastropathy is to initiate a proton pump inhibitor (PPI) therapy at standard dose once daily for 4-8 weeks, with subsequent dose adjustment based on response.

Assessment of Current Situation

The patient presents with:

• Chronic acid reflux symptoms
• Sensation of "food stuck in stomach" with reflux
• Partial response to OTC antacids with symptom recurrence when not taking them
• Occasional nocturnal reflux
• No dysphagia
• EGD findings: normal esophagus and duodenum, reactive gastropathy in antrum
• Biopsies: negative for H. pylori, intestinal metaplasia, and carcinoma
• Benign squamous mucosa in esophagus with features of reflux

Treatment Approach

Step 1: Initiate PPI Therapy

• Start with standard dose PPI once daily for 4-8 weeks 1, 2, 3
  • Omeprazole 20 mg once daily, or
  • Lansoprazole 30 mg once daily, or
  • Pantoprazole 40 mg once daily, or
  • Rabeprazole 20 mg once daily

Step 2: Assess Response at 4-8 Weeks

• If adequate response: taper to lowest effective dose or convert to on-demand therapy 1
• If partial or no response: increase to twice daily dosing or switch to a more effective acid suppressive agent 1, 2

Step 3: Adjunctive Therapy Based on Symptoms

• For breakthrough symptoms: alginate-containing antacids 2
• For nocturnal symptoms: nighttime H2 receptor antagonists 1, 2
• For sensation of "food stuck in stomach" (suggesting possible gastroparesis): consider adding a prokinetic agent 2

Evidence-Based Rationale

The American Gastroenterological Association (AGA) clinical practice update recommends a 4-8 week trial of single-dose PPI therapy for patients with typical reflux symptoms 1. This patient's endoscopic findings of reactive gastropathy and reflux features on biopsy, along with her clinical presentation, support the diagnosis of GERD requiring acid suppression therapy.

The patient's sensation of "food stuck in stomach" may suggest delayed gastric emptying, which can exacerbate GERD symptoms by increasing intragastric pressure and promoting reflux 2. This symptom, combined with the finding of reactive gastropathy, indicates that a combination approach with PPI and potentially a prokinetic agent may be beneficial.

Important Considerations

• Administration instructions: Take PPI 30-60 minutes before meals for optimal effect 2, 3
• Lifestyle modifications: Recommend weight management if applicable, elevating the head of the bed, avoiding meals within 3 hours of bedtime, and identifying/avoiding trigger foods 2
• Duration of therapy: If symptoms resolve with initial therapy, attempt to wean to lowest effective dose; for patients requiring chronic PPI therapy, consider objective reflux testing within 12 months to confirm the need for long-term therapy 1
• Monitoring: If symptoms persist despite optimized PPI therapy, consider additional diagnostic testing including prolonged wireless pH monitoring off medication 1

Potential Pitfalls

1. Inadequate PPI dosing or timing: Ensure proper administration 30-60 minutes before meals
2. Non-acid reflux: Some patients may have weakly acidic or non-acid reflux that responds poorly to acid suppression alone
3. Overlooking gastroparesis: The sensation of "food stuck in stomach" warrants consideration of prokinetic therapy
4. Long-term PPI safety: While initiating therapy is appropriate, be mindful of potential long-term effects including vitamin B12 deficiency, hypomagnesemia, and fundic gland polyps with prolonged use 3

By following this approach, you can effectively manage this patient's chronic acid reflux symptoms while addressing the underlying reactive gastropathy, with the goal of improving her quality of life and preventing complications of chronic GERD.
