Objectives:
The metaplastic intestinal epithelium in Barrett esophagus (BE) occasionally contains Paneth cells; however, little is known regarding the prevalence and significance of Paneth cell metaplasia (PCM) in BE.
Methods:
We evaluated 757 esophageal biopsy specimens with intestinal metaplasia (IM) for PCM. Outcome analysis was performed in 299 cases with complete clinical data using multinomial logistic regression.
Results:
Thirty-one percent (234/757) of the IM cases showed PCM. Paneth cells are decreased when BE epithelium becomes increasingly dysplastic. Long-segment BE shows significantly more PCM than short-segment BE. On follow-up biopsies, patients without PCM (NPCM) are three times more likely to regress than patients with PCM, regardless of dysplasia, BE segment length, age, or sex. However, there is no significant difference in terms of progression to dysplasia/adenocarcinoma between the PCM and NPCM groups.
Conclusions:
The presence of PCM is associated with less disease regression and is not associated with more disease progression.
Insights
Paneth cell metaplasia (PCM) in Barrett esophagus (BE) is common, associated with less regression, but not increased progression to dysplasia or adenocarcinoma. This finding is important for understanding BE progression.
Area of Science:
- Gastroenterology
- Oncology
- Pathology
Background:
- Barrett esophagus (BE) is a metaplastic change in the esophageal lining.
- Paneth cells are occasionally found in the metaplastic intestinal epithelium of BE.
- The prevalence and clinical significance of Paneth cell metaplasia (PCM) in BE are not well understood.
Purpose of the Study:
- To determine the prevalence of Paneth cell metaplasia (PCM) in Barrett esophagus (BE).
- To investigate the association between PCM and clinical outcomes in BE, including disease regression and progression to dysplasia or adenocarcinoma.
Main Methods:
- Esophageal biopsy specimens (n=757) with intestinal metaplasia (IM) were analyzed for PCM.
- Clinical outcome analysis was conducted on 299 cases with complete data using multinomial logistic regression.
Main Results:
- Paneth cell metaplasia (PCM) was identified in 31% of IM cases.
- PCM prevalence was higher in long-segment BE compared to short-segment BE.
- Paneth cells decreased with increasing dysplasia.
- Patients without PCM (NPCM) showed a threefold higher likelihood of regression compared to patients with PCM.
- No significant difference in progression to dysplasia or adenocarcinoma was observed between the PCM and NPCM groups.
Conclusions:
- Paneth cell metaplasia (PCM) in Barrett esophagus (BE) is associated with reduced disease regression.
- The presence of PCM does not correlate with an increased risk of progression to dysplasia or adenocarcinoma in BE.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
