Chest
|June 1, 1981
Summary
Methyldopa, a medication for high blood pressure, can induce a lupus-like syndrome. This syndrome, characterized by fever and inflammation, resolved after discontinuing the drug, as seen in a patient with antinuclear antibody positivity.
Area of Science:
- Cardiology
- Rheumatology
- Pharmacology
Background:
- Methyldopa is a commonly prescribed antihypertensive agent.
- Drug-induced lupus erythematosus (DILE) is a recognized adverse effect of various medications.
Observation:
- A 50-year-old woman developed pleural pericarditis and fever while on methyldopa therapy.
- She also exhibited a positive antinuclear antibody (ANA) test result.
Findings:
- Discontinuation of methyldopa led to complete resolution of clinical symptoms.
- The patient's antinuclear antibody titer normalized after drug withdrawal.
Implications:
- This case highlights methyldopa as a potential cause of drug-induced lupus-like syndrome.
- Clinicians should consider methyldopa when evaluating patients presenting with lupus-like symptoms.
- Early recognition and drug withdrawal can lead to favorable patient outcomes.
