Macrophage activation syndrome complicating early course of adult-onset Still’s disease
Introduction. Adult-onset Still?s disease is a rare inflammatory disorder of unknown etiology. It can be complicated by macrophage activation syndrome, potentially life-treatening condition. While macrophage activation syndrome and adult-onset Still?s disease shared similar features, early recognition is very difficult in clinical praxis. Case outline. We report a young woman, which illness was presented suddenly, with spiking fever, sore throat, myalgia, arthralgia and maculopapular rash. In suspicion of sepsis, she received antibiotics, despite no evidence of infection. After two weeks, her condition worsened, which has been followed by cytopenia, elevated liver enzymes and high serum levels of ferritin. She was diagnosed as macrophage activation syndrome in early course of adult-onset Still?s disease. She was treated with high dose corticosteroids and cyclosporine A and recovered completely. Conclusion. Macrophage activation syndrome can occur at the beginning of adult-onset Still?s disease. Early recognition and timely administration of immunosuppressive drugs are important for successful outcome in this condition.
