Pemphigus erythematosus relapse associated with atorvastatin intake

Area of Science:

• Immunology
• Pharmacology
• Dermatology

Background:

• Statins (HMG-CoA reductase inhibitors) are widely used for cardiovascular disease prevention.
• While generally safe, rare adverse effects like myositis and rhabdomyolysis can occur.
• Emerging evidence suggests long-term statin use may induce autoimmune reactions.

Observation:

• A 70-year-old male patient with a history of autoimmune conditions was treated with atorvastatin.
• The patient experienced a relapse of pemphigus erythematosus following atorvastatin intake.

Findings:

• Atorvastatin intake was temporally associated with the relapse of pemphigus erythematosus.
• Statins, as proapoptotic agents, may release nuclear antigens, potentially inducing autoantibodies.

Implications:

• This case highlights a potential link between statin use and autoimmune diseases like pemphigus erythematosus.
• Further research is needed to elucidate the mechanisms of statin-induced autoimmunity.
• Clinicians should consider autoimmune reactions in patients on long-term statin therapy presenting with relevant symptoms.
