About this study

Helicobacter pylori is a Gram-negative, spiral-shaped bacterium that infects up to 50% of the world's population, residing in the gastric mucosa and using the mucus layer for protection from the stomach's high acidity. Its clinical significance is profound: it is classified as a Group 1 carcinogen by the World Health Organization and is a primary cause of chronic gastritis, peptic ulcers, gastric lymphoma, and gastric carcinoma. The current first-line treatment, a PPI-based triple therapy (PPI + clarithromycin + amoxicillin), is experiencing a decline in efficacy (cure rates of 50-70%) due to widespread antibiotic resistance and compliance issues. To overcome this, newer agents like Vonoprazan Fumarate, a Potassium-Competitive Acid Blocker (P-CAB), are being adopted. Vonoprazan works by reversibly inhibiting the H+, K+ ATPase pump achieving stronger and longer-lasting acid suppression than PPIs because it does not require acid activation and is more stable in an acidic environment. In addition to pharmacological treatment, adjunctive therapies show promise. Vitamin D, acting through Vitamin D Receptor (VDR), assists in eradication by upregulating antimicrobial proteins like beta-defensin and cathelicidin, and its metabolite can cause bacterial cell lysis. Probiotics (primarily Lactobacillus and Bifidobacterium strains) enhance eradication rates by restricting bacterial growth, inhibiting adhesion, and exerting an anti-inflammatory effect through decreased interleukin-8 produc…
