Medication-related osteonecrosis of the jaw leading to sepsis in a patient with rheumatoid arthritis: A case report and clinical implications

Key clinical message: Chronic use of bisphosphonates, in combination with immunosuppressive therapy, increases the risk of jaw osteonecrosis. When sepsis occurs in patients receiving bisphosphonate, osteonecrosis of the jaw should be considered a potential source of infection.

Abstract: Reports of medication-related osteonecrosis of the jaw (MRONJ) accompanied by sepsis are limited. A 75-year-old female patient with rheumatoid arthritis, receiving treatment with bisphosphonate and abatacept, developed sepsis secondary to MRONJ. When sepsis occurs in patients receiving bisphosphonate, osteonecrosis of the jaw should be considered a potential source of infection.
