Summary

Colchicine overdose caused severe gastrointestinal symptoms, bone marrow hypoplasia, and pneumonia. Histopathology revealed mitotic figures in the gut, confirming colchicine toxicity.

Area of Science:

  • Toxicology
  • Gastroenterology
  • Hematology

Background:

  • Colchicine is a medication used to treat gout and familial Mediterranean fever.
  • Overdoses can lead to severe toxicity, affecting multiple organ systems.

Observation:

  • A 45-year-old male presented with vomiting, nausea, and diarrhea after colchicine ingestion.
  • During hospitalization, a dramatic decrease in white blood cell count was observed.

Findings:

  • Postmortem examination revealed bilateral bronchopneumonia, bone marrow hypocellularity, and reduced hematopoietic cells.
  • Histological analysis showed numerous metaphasic mitotic figures in the gastric and small bowel epithelia.
  • Colchicine was quantified in antemortem plasma and postmortem blood and bile using high-pressure liquid chromatography.

Implications:

  • This case highlights the severe and potentially fatal consequences of colchicine overdose.
  • The histological findings of mitotic figures suggest colchicine's mechanism of action involves disruption of cell division.
  • Early detection and quantification of colchicine are crucial for managing toxicity.
