Summary
This case report details a patient who developed classic drug-induced lupus (DIL) from clozapine, a serious adverse effect. The condition resolved upon clozapine withdrawal and recurred upon rechallenge, confirming the link.
Area of Science:
- Psychiatry
- Rheumatology
- Clinical Pharmacology
Background:
- Clozapine is an atypical antipsychotic used for treatment-resistant schizophrenia.
- Drug-induced lupus (DIL) is a condition mimicking systemic lupus erythematosus, often caused by medications.
Observation:
- A 32-year-old woman with schizophrenia developed DIL symptoms while on clozapine.
- Discontinuation of clozapine led to remission, but symptoms reappeared upon rechallenge.
Findings:
- The patient presented with classic clinical and laboratory markers of DIL.
- The Naranjo probability scale indicated a highly probable relationship between clozapine and DIL.
- This case represents a classic presentation of clozapine-induced lupus.
Implications:
- Drug-induced lupus should be considered a potential serious adverse effect of clozapine.
- A high index of suspicion is crucial for diagnosing DIL in patients taking clozapine.
- This case highlights the importance of careful monitoring for adverse reactions to antipsychotic medications.
