Cure8 research brief
Zinc deficiency is common in UC, and this study suggests that changes in zinc‑dependent enzyme activity in the gut lining are linked with local inflammation. If confirmed, mucosal enzyme activity might help explain altered zinc handling in UC or serve as a tissue biomarker of inflammation.
Clinicians and researchers studying ulcerative colitis, nutritional status (zinc) in IBD, and mucosal biomarkers; adult patients with UC interested in research on nutrient–inflammation links.
This was a single‑center prospective observational study of 29 UC patients who underwent colonoscopy with tissue sampling. Researchers measured serum zinc, serum and mucosal activity of two zinc‑dependent enzymes (heat‑resistant alkaline phosphatase and NT5E/CD73), and mucosal inflammatory cytokine mRNA.
Lower serum zinc was seen in patients not in clinical or endoscopic remission. Higher mucosal (but not serum) zinc‑dependent enzyme activity correlated with histologic inflammation and with greater mucosal inflammatory cytokine expression.
The study suggests a local (mucosal) relationship between zinc‑dependent enzyme activity and inflammation in UC, not explained by serum enzyme activity. These findings are associative and do not prove causation; the study is small and single‑center.
The article abstract reports a small (n=29), single‑center observational study. Associations reported do not establish causality, and the summary is based on the paper abstract rather than full peer‑reviewed replication across centers.

Vitamin D supplementation is commonly considered in people with IBD because deficiency is frequent and low vitamin D may relate to inflammation.
Researchers are exploring plant-derived polysaccharides as potential therapies that might reduce inflammation and protect the intestinal barrier. For people with UC, therapies that reduce pyroptosis and restore...
The review brings together evidence that genetics, immune responses, the gut microbiome, and environmental triggers interact to cause Crohn's disease and ulcerative colitis.
