Lymph follicular cholecystitis.

Y Hatae, M Kikuchi

    Acta Pathologica Japonica

    Summary
    This summary is machine-generated.

    Severe lymphocytic reactions in cholecystitis cases were linked to gram-negative bacterial infections like E. coli. Gallstones did not show a significant influence on these reactions, suggesting a focus on bacterial causes for this specific cholecystitis presentation.

    Area of Science:

    • Gastroenterology
    • Pathology
    • Microbiology

    Background:

    • Cholecystitis, inflammation of the gallbladder, can present with varied histopathological findings.
    • Lymphocytic infiltration in the gallbladder wall is an observed, though not fully understood, phenomenon.
    • The role of bacterial infection versus gallstones in driving specific inflammatory responses in cholecystitis requires further elucidation.

    Purpose of the Study:

    • To investigate the potential causes of severe lymphocytic reactions observed in cholecystitis cases.
    • To differentiate cases with severe lymphocytic reactions as a distinct entity, termed lymph follicular cholecystitis.
    • To explore the association between bacterial infections and gallstone presence in the context of these reactions.

    Main Methods:

    Related Experiment Videos

  • Histopathological examination of 131 cholecystitis and/or cholelithiasis cases.
  • Selection of ten cases exhibiting severe lymphocytic reactions for detailed analysis.
  • Microbiological assessment to identify bacterial presence in bile samples.

    • Main Results:

    • Ten cases of cholecystitis demonstrated severe lymphocytic reactions.
    • Gram-negative bacterial infections, specifically Escherichia coli (E. coli) and Klebsiella pneumoniae, were frequently associated with these reactions.
    • The presence of gallstones did not show a definitive influence on the severity of lymphocytic infiltration.

    Conclusions:

    • Severe lymphocytic reactions in cholecystitis may represent a distinct pathological entity, potentially 'lymph follicular cholecystitis'.
    • Gram-negative bacterial infections are implicated as a likely cause of these severe lymphocytic reactions.
    • Further investigation into bacterial infections in bile is warranted for cases presenting with lymph follicular cholecystitis.
