Resin related enterocolitis: An underreported co-occurrence.

Area of Science:

• Gastroenterology
• Pathology
• Nephrology

Background:

• Medication resins are crucial for managing electrolyte balance in patients with renal compromise.
• These resins can paradoxically induce significant gastrointestinal tract damage, which is often reversible.
• The damage can manifest as colitis, complicating diagnosis.

Observation:

• Gastrointestinal biopsy specimens from patients on medication resins may contain these resin particles.
• Resin-induced colitis can present with symptoms similar to inflammatory bowel disease (IBD).
• Lack of clinical history can mislead pathologists, obscuring the resin-related etiology.

Findings:

• Microscopic identification of medication resins in gastrointestinal biopsies is key.
• Histopathological features of resin-induced colitis can be distinct but require careful evaluation.
• The condition is often underdiagnosed due to its resemblance to IBD and limited patient history.

Implications:

• Timely recognition of resin-related colitis is vital to prevent further gastrointestinal injury.
• Meticulous history-taking and communication between clinicians and pathologists are essential.
• Pathologists must consider medication resin toxicity in differential diagnoses for colitis, especially in renal patients.
