Intravenous Anakinra for Treating Macrophage Activation Syndrome in Adult-Onset Still's Disease. | LitMetric

AI Article Synopsis

Article Abstract

Background: Adult-onset Still's disease (AOSD) is a rare systemic inflammatory disease characterized by fever, rash, arthritis, and multi-organ involvement. Macrophage activation syndrome (MAS), a serious complication of AOSD, poses significant diagnostic and therapeutic challenges.

Case Presentation: A 32-year-old male was diagnosed with AOSD in 2020 after being hospitalized for a fever of unknown origin and elevated liver enzymes. The patient was initially treated with corticosteroids and methotrexate but subsequently discontinued both treatment and follow-up. In September 2023, he presented with fever, sore throat, and elevated inflammatory markers. After screening for infections, methylprednisolone (MP) treatment was initiated because of AOSD activation. The following day, the patient was admitted to the intensive care unit due to an altered state of consciousness. Brain magnetic resonance imaging revealed brainstem involvement. Empirical treatments were initiated, including intravenous MP, and immunoglobulin therapy. Due to suspected macrophage activation syndrome (MAS), anakinra (ANA) infusion was initiated. Significant improvement was observed after the ANA infusion.

Conclusion: This case highlights the complex management of severe AOSD complications, emphasizing the role of early recognition, aggressive therapy, and multidisciplinary care in improving outcomes.

Learning Points: Macrophage activation syndrome (MAS) is a serious complication of adult-onset Still's disease characterized by systemic inflammation. Early recognition and prompt initiation of treatment are crucial due to the high mortality rate associated with MAS, especially when neurologic symptoms are present.Clinicians should not delay treatment pending confirmatory diagnostic tests when MAS is suspected, as early intervention can significantly impact patient outcomes.Anakinra, an interleukin-1 inhibitor, is typically administered subcutaneously but has shown promise when administered intravenously, particularly in severe cases of MAS.
