Enterococcal pyomyositis in a rheumatoid arthritis patient under biologic therapy

Key Points

• Enterococcal pyomyositis developed in a patient on biologic therapy, leading to severe complications.
• The patient experienced muscle infections due to weakened immune responses from ongoing treatment.
• Observed infection challenges conventional assumptions regarding safety in biologic therapy for rheumatoid arthritis.
• Further investigation is necessary to understand risks and recommend preventive strategies.
