Cocaine inhalation can cause severe, recurrent alveolar hemorrhage in young adults. This case highlights the importance of considering drug use in unexplained diffuse alveolar hemorrhage.

Area of Science:

  • Pulmonary Medicine
  • Toxicology
  • Cardiovascular Research

Background:

  • Diffuse alveolar hemorrhage (DAH) is a rare but serious condition.
  • Common causes include immunological and infectious diseases.
  • This case presents a young adult with recurrent DAH and severe anemia.

Observation:

  • The patient exhibited hemoptysis, dyspnea, and bilateral lung opacities on imaging.
  • Bronchoscopy confirmed diffuse bleeding, with negative initial investigations for common causes.
  • Toxicology revealed cannabis and cocaine use, initially denied by the patient.

Findings:

  • Lung biopsy showed diffuse alveolar damage consistent with cocaine inhalation.
  • The patient subsequently admitted to smoking "improved joints" (cocaine).

Implications:

  • Cocaine inhalation should be considered as a potential cause of DAH, especially in young adults.
  • This case underscores the diagnostic challenges and the need for thorough toxicological screening.
  • Early identification and cessation of drug use are crucial for managing DAH in such cases.
