A 52-year-old man from Delhi presents with a 3-month history of epigastric pain relieved by food and antacids. Upper endoscopy reveals a 1.5 cm antral ulcer with clean base. Rapid urease test is positive. He is not on NSAIDs. What is the most appropriate next step in management?

Explanation

## Clinical Scenario Analysis This patient has **H. pylori-positive peptic ulcer disease** (PUD) confirmed by positive rapid urease test on endoscopy. The management of H. pylori-associated PUD follows a well-established eradication protocol. ## Management Algorithm for H. pylori-Positive PUD ```mermaid flowchart TD A[H. pylori-positive PUD confirmed]:::outcome --> B{Eradication therapy indicated?}:::decision B -->|Yes| C[Triple or Quadruple therapy for 14 days]:::action C --> D[Omeprazole 20 mg BD + Amoxicillin 1 g BD + Clarithromycin 500 mg BD]:::action D --> E[Continue PPI monotherapy for 4-8 weeks total]:::action E --> F[Test of cure after 4 weeks if symptoms persist]:::action B -->|No| G[PPI monotherapy] ``` ## Key Point: **Triple therapy is the gold standard first-line eradication regimen** for H. pylori-positive PUD in India [cite:Harrison 21e Ch 297]. The standard regimen is: - Omeprazole 20 mg BD (or pantoprazole 40 mg BD) - Amoxicillin 1 g BD - Clarithromycin 500 mg BD - Duration: 14 days ## High-Yield: **After eradication therapy completion**, continue PPI monotherapy for a total of 4–8 weeks to allow ulcer healing. Test of cure (urea breath test or stool antigen) is performed 4 weeks after completing eradication therapy if symptoms persist. ## Clinical Pearl: The clean base of the ulcer on endoscopy is reassuring and does **not** suggest malignancy in this context. Biopsy for malignancy is indicated only if the ulcer has an irregular margin, raised edges, or nodular base—features of a malignant ulcer. ## Why This Approach? 1. **Eradication cures the disease**: H. pylori eradication heals >90% of ulcers and prevents recurrence, eliminating the need for long-term PPI therapy. 2. **Guideline-mandated**: All major guidelines (ASGE, BSG, ASGE) recommend triple therapy as first-line for H. pylori eradication. 3. **Cost-effective**: A 2-week course of triple therapy is more economical than indefinite PPI monotherapy.
