Ultrastructural changes in chronic inflammatory enteropathies-a comparison between dogs and humans

Area of Science:

• Veterinary Medicine
• Gastroenterology
• Pathology

Background:

• Chronic inflammatory enteropathies (CIEs) are complex canine diseases.
• Current diagnostic methods like endoscopy and histopathology have limitations in subclassifying CIEs and predicting treatment response.
• Healing of mucosal disease and ultrastructural evaluation are understudied in canine CIE.

Purpose of the Study:

• To evaluate the literature on ultrastructural mucosal lesions in canine CIE and human inflammatory bowel disease (IBD).
• To highlight the potential of ultrastructural evaluation as a sensitive diagnostic tool for canine CIE.
• To propose future research directions for studying ultrastructural mucosal lesions in canine CIE.

Main Methods:

• Literature review and synthesis of existing research on ultrastructural lesions in canine CIE and human IBD.
• Comparative analysis of ultrastructural findings between canine CIE and human IBD.

Main Results:

• Canine CIE serves as a valuable spontaneous model for human IBD.
• Ultrastructural mucosal lesions may be detected with higher sensitivity compared to light microscopy.
• These ultrastructural changes might precede or persist after clinical and histological resolution.

Conclusions:

• Ultrastructural evaluation of the canine mucosa warrants further investigation for CIE diagnosis and monitoring.
• This approach may provide deeper insights into disease pathogenesis and remission.
• Future studies should focus on the diagnostic and prognostic value of ultrastructural mucosal lesions in canine CIE.
