Carditis etiology is controversial. This study found Helicobacter pylori (Hp) associated with carditis in normal SCJ patients, while gastroesophageal reflux linked to carditis in patients with irregular SCJ segments.

Area of Science:

  • Gastroenterology
  • Pathology
  • Endoscopy

Background:

  • Carditis etiology remains debated.
  • Understanding carditis mechanisms is crucial for patient management.

Purpose of the Study:

  • To investigate carditis prevalence and pathogenetic mechanisms.
  • To differentiate etiological factors based on endoscopic and histological findings.

Main Methods:

  • Biopsies from 664 patients analyzed histologically.
  • Specimens stained for mucosa type, inflammation, metaplasia, and Helicobacter pylori (Hp).
  • Correlation of findings with endoscopic appearance of the squamocolumnar junction (SCJ).

Main Results:

  • Carditis prevalence was high (90.6% and 87.4%) in both patient groups.

  • Hp infection strongly associated with carditis in normal SCJ.
  • Gastroesophageal reflux features trended with carditis in irregular SCJ.
  • Cardiac/mixed mucosa rare in the endoscopically defined cardia.

    • Conclusions:

    • Two distinct etiologies for carditis suggested: Hp-associated in normal SCJ, and reflux-associated in irregular SCJ.
    • Histological analysis of SCJ biopsies is key to understanding carditis.
    • Findings highlight the importance of SCJ appearance in diagnosing carditis.
