No Independent Association Between Serum Zinc Levels and Endoscopic Disease Activity Assessed by the Ulcerative Colitis Endoscopic Index of Severity: A Single-Center Retrospective Study

Why This Matters

The study suggests that serum zinc by itself may not be a reliable indicator of endoscopic inflammation in UC; nutritional status and inflammation (for example albumin and CRP) can confound zinc levels.

Who Should Pay Attention

Clinicians treating ulcerative colitis; researchers of IBD biomarkers; patients tracking micronutrient status

What To Know

This single-center retrospective study compared serum zinc measurements taken within 30 days of colonoscopy to the UCEIS in 40 patients (44 pairs). In univariate analysis there was a weak, non-significant negative correlation between zinc and UCEIS.

In multivariable models adjusted for age, sex, disease extent, serum albumin, CRP, and advanced therapy, serum zinc was not independently associated with UCEIS. When albumin was removed from the model, zinc did show a statistically significant association, suggesting nutritional and inflammatory status influence zinc levels.

Practical takeaway: serum zinc alone did not reliably reflect endoscopic disease severity in this cohort; clinicians should consider albumin and inflammatory markers when interpreting zinc results.

Keep In Mind

Single-center retrospective design and small sample size limit generalizability. The provided content is based on the article abstract rather than full peer-reviewed supplementary data.
