[Recommendations for the diagnosis and treatment of rheumatic diseases-related hemophagocytic syndrome in China].

Hemophagocytic syndrome (HPS), which is currently named as hemophagocytic lymphohistiocytosis (HLH), is a hyperinflammatory syndrome characterized by persistent fever, hepatosplenomegaly, pancytopenia and hemophagocytosis found in bone marrow, liver, spleen and lymph nodes due to excessive activation of macrophages and cytotoxic T cells. Macrophage activation syndrome (MAS) is a specific form of HLH induced by autoinflammatory/autoimmune disorders which can be life-threatening and requires multiple disciplines. In order to improve clinicians' understanding of MAS and standardize the clinical diagnosis and treatment practice of MAS, the rheumatology branch of Chinese Rheumatology Association organized domestic experts to formulate the diagnosis and treatment standard, in order to improve the diagnosis and treatment level of MAS and improve the prognosis of patients.噬血细胞综合征（HPS）又称噬血细胞性淋巴组织细胞增多症（HLH），其中继发于风湿性疾病的HLH亦称为巨噬细胞活化综合征（MAS）。HLH是细胞毒T细胞和单核-巨噬细胞系统过度激活，临床上以持续发热、肝脾肿大、全血细胞减少及骨髓、肝、脾、淋巴结组织出现噬血现象为特征的综合征。MAS是风湿性疾病的高危并发症，需要多学科密切合作。为提高临床医师对MAS的认识，规范MAS的临床诊治实践，中华医学会风湿病学分会组织国内相关专家制定了本规范，旨在提高MAS的诊治水平，改善患者预后。.
