Pleural effusion associated with D-penicillamine therapy: a case report

Area of Science:

• Pulmonology
• Pharmacology
• Clinical Medicine

Background:

• D-penicillamine is a chelating agent used to treat conditions like Wilson's disease and rheumatoid arthritis.
• Pleural effusion is a known, albeit rare, side effect of some medications.
• The long-term effects and potential complications of D-penicillamine require ongoing investigation.

Observation:

• A case of a large pleural effusion developed in a patient undergoing long-term D-penicillamine treatment.
• The effusion was clinically significant and required intervention.
• No prior reports linked D-penicillamine therapy to pleural effusion.

Findings:

• This case report documents a novel association between prolonged D-penicillamine use and the development of large pleural effusion.
• The temporal relationship suggests a potential causal link, although further studies are needed to confirm this.
• This represents a previously unrecognized adverse drug reaction.

Implications:

• Clinicians should consider pleural effusion in the differential diagnosis of respiratory symptoms in patients on long-term D-penicillamine.
• Awareness of this potential complication may lead to earlier diagnosis and management.
• Further research is warranted to elucidate the mechanism and incidence of this adverse event.
