Fatal bronchiolitis obliterans associated with chrysotherapy.

Area of Science:

• Pulmonary Medicine
• Rheumatology
• Toxicology

Background:

• Rheumatoid arthritis is a chronic autoimmune disease primarily affecting joints.
• Gold salts have been used historically to treat rheumatoid arthritis due to their anti-inflammatory properties.
• Bronchiolitis obliterans is a severe, irreversible obstructive lung disease.

Observation:

• A patient undergoing gold therapy for rheumatoid arthritis developed progressive respiratory failure.
• The patient's condition was diagnosed as bronchiolitis obliterans.
• The development of bronchiolitis obliterans was temporally linked to gold administration.

Findings:

• Gold therapy was identified as the likely cause of fatal bronchiolitis obliterans in this patient.
• Review of literature suggests a potential association between gold treatment and lung injury.
• Bronchiolitis obliterans represents a rare but serious adverse effect of gold therapy.

Implications:

• Clinicians should be vigilant for pulmonary complications in rheumatoid arthritis patients receiving gold therapy.
• Alternative treatments for rheumatoid arthritis may be preferable to minimize risks of bronchiolitis obliterans.
• Further research is warranted to elucidate the mechanisms linking gold salts to lung toxicity.
