Cocaine use is linked to two vasculitis types: midline destructive lesions from cocaine itself and ANCA-associated vasculitis from levamisole contamination. Early diagnosis and treatment are crucial for managing these serious side effects.

Area of Science:

  • Rheumatology
  • Toxicology
  • Dermatology

Background:

  • Cocaine use is increasing globally, presenting various health risks.
  • Vasculitis is a recognized, albeit uncommon, side effect of cocaine use.
  • Two distinct vasculitic syndromes are associated with cocaine consumption.

Approach:

  • This review details the clinical presentation, pathogenesis, and diagnostic considerations for cocaine-associated vasculitis.
  • It differentiates between cocaine-induced midline destructive lesions and ANCA-associated vasculitis.
  • Emphasis is placed on the role of levamisole contamination in the latter.

Key Points:

  • Cocaine-induced midline destructive lesions result from direct vasoconstriction, causing ischemic necrosis and nasal septal perforation.

  • ANCA-associated vasculitis is linked to levamisole, a common cocaine adulterant, and may be MPO/PR3 positive.
  • Clinical manifestations include skin lesions, joint pain, ear, nose, and throat issues, and a low white blood cell count (agranulocytosis).

    • Conclusions:

    • Recognizing these distinct vasculitic syndromes is critical for effective patient management.
    • A high index of suspicion is necessary for timely diagnosis and treatment of cocaine-induced vasculitis.
    • Awareness of the association between cocaine, levamisole, and vasculitis is essential for healthcare providers.
