INTRODUCTION: This case report signifies the need to systemically assess antimalarial toxicity in those undergoing long-term treatment.
CASE REPORT: A 59-year-old man with a history of ischemic-labeled heart disease revealed by conduction disorders and cutaneous lupus treated initially with hydroxychloroquine followed by chloroquine consulted for asthenia and weight loss. Clinically, he had a muscular atrophy, a motor deficit, and an abolition of the osteo-tendinous reflexes in the lower limbs. Adverse drug effects of the antimalarial therapy were suspected-specifically, muscular and cardiac toxicity. The diagnosis was confirmed with a muscle biopsy, which showed typical and florid vacuolar myopathy. Cessation of the drug resulted in a slow regression of symptoms.
CONCLUSION: Cardiac and muscular toxicity related to antimalarials are rare and sometimes fatal; thus, they must be systematically assessed in a patient with several years of exposure. A muscle biopsy could be sufficient to allow for the diagnosis.
