ABSTRACT

A síndrome de ativação macrofágica (SAM) ou síndrome hemofagocítica secundária (reativa) consiste de uma rara, grave e potencialmente fatal complicação das doenças reumáticas crônicas, particularmente da artrite idiopática juvenil de início sistêmico, doença de Still do adulto e lúpus eritematoso sistêmico. É caracterizada pela excessiva ativação dos macrófagos, resultando febre, hepatoesplenomegalia, linfadenomegalia, envolvimento neurológico, graus variáveis de citopenias, hiperferritinemia, distúrbio hepático, coagulação intravascular e freqüente falência de múltiplos órgãos. Também ocorre em associação com neoplasias, imunodeficiências e variedade de agentes infecciosos virais (sobretudo do grupo do herpes), bacterianos e fúngicos. Relatamos um caso de SAM decorrente de infecção viral aguda pelo vírus Epstein-Barr tratado com corticóide oral


The macrophage activation syndrome (MAS) or secondary haemophagocytic syndrome (reactive) is an uncommon, severe and life-threatening complication of chronic rheumatic diseases, especially systemic onset juvenile idiopathic arthritis, adult-onset Still disease and systemic lupus eritematosus. It is characterized by the excessive activation of macrophages, resulting in fever, hepatoesplenomegaly, lymphadenopathy, neurological involvement, variable cytopenias, hyperferritinemia, liver disease, intravascular coagulation, often resulting in fatal multiple organ failure. Besides chronic rheumatic diseases, it is also seen in a heterogeneous group of diseases like neoplasms, imunodeficiencies and viruses (especially the herpes group), bacteria and fungi infections. We describe a case report of one patient with MAS triggered by Epstein-Barr virus infection treated with oral corticosteroid.
