“…8,9 The clinical manifestations can be explained by overproduction of pro-infl ammatory cytokines (interleukin 1, tumoral necrosis factor, gamma-interferon, among others), which are responsible for this severe complication. [10][11][12] The diagnostic diffi culty is due to the fact that disease activity shares common signs and symptoms, in addition to clinical pictures associated with infectious agents. 13,14 According to many authors the presence hiperferritinemia is a highly suggestive sign of reactive macrophage disease and this factor associated with the bone marrow aspirate has defi ned RHS clinical features.…”

“…Macrophage Activation Syndrome Triggered by Epstein-Barr Virus Adolpho X. de Carvalho Filho (1) , Fabrício de Oliveira Correa (2) , Ivan Schumann (3) Recebido em macrófagos, levando à superprodução de citocinas (TNF-α, IL-1, IL-6 e interferon) (5) . Ela é clinicamente reconhecida por ocorrer principalmente na forma sistêmica da AIJ (1,4) , e foi demonstrado que a atividade citotóxica da célula natural killer (NK) foi significativamente menor nesses pacientes que nos pacientes com outras formas de AIJ (6) .…”

“…Ela é clinicamente reconhecida por ocorrer principalmente na forma sistêmica da AIJ (1,4) , e foi demonstrado que a atividade citotóxica da célula natural killer (NK) foi significativamente menor nesses pacientes que nos pacientes com outras formas de AIJ (6) . Tais dados sugerem que essas disfunções citotóxicas e/ou deficiências imunorregulatórias das células NK são anormalidades etiopatogênicas importantes para o desenvolvimento da SAM (6) .…”
