What was done

Two patients with chronic atrophic gastritis (CAG)—one secondary to autoimmune gastritis and the other secondary to Helicobacter pylori infection—were treated with oral zinc L-carnosine (39.5 mg twice daily) for at least 12 months for persistent dyspeptic symptoms. Endoscopic evaluation, histologic reassessment, and gastric biomarker testing (pepsinogen I, pepsinogen II, and gastrin 17) were conducted after at least 12 months of treatment.

What was found

The authors report clinically significant improvements in dyspeptic symptoms, histologic features of chronic atrophic gastritis, and gastric function biomarkers (pepsinogen I, pepsinogen II, and gastrin 17) in both patients. The abstract provides no specific numerical values, baseline scores, or magnitude of changes.

Why it matters

This report provides preliminary clinical observation that zinc L-carnosine may improve symptoms and mucosal features in chronic atrophic gastritis.

Limits

The study is an uncontrolled case series of only two patients (n = 2), precluding any definitive causal inference. The abstract reports no quantitative data, and the design lacks blinding, controls, and long-term clinical outcome follow-up.
