    QJM : monthly journal of the Association of Physicians·2013

    Area of Science:

    • Toxicology
    • Hematology
    • Clinical Medicine

    Background:

    • Colchicine, a medication used for gout and familial Mediterranean fever, has a narrow therapeutic index.
    • Overdose can lead to severe multi-organ toxicity, with a high mortality rate.
    • Suicidal overdose presents unique challenges in management and understanding of toxic effects.

    Observation:

    • A patient presented with a suicidal overdose of colchicine.
    • The patient developed significant complications affecting the hematopoietic, gastrointestinal, respiratory, and central nervous systems.
    • Heinz bodies were identified in red blood cells, a previously undocumented finding in colchicine overdose.

    Findings:

    • Colchicine overdose can induce Heinz body formation in erythrocytes.

  • Severe central nervous system complications are a significant cause of mortality in colchicine poisoning.
  • Multi-system involvement necessitates intensive supportive care.

    • Implications:

    • This case expands the known spectrum of hematological abnormalities associated with colchicine toxicity.
    • The presence of Heinz bodies may serve as an additional diagnostic clue in severe colchicine poisoning.
    • Understanding these complications can guide clinical management and improve patient outcomes in future overdose cases.
