A retrospective study was done to evaluate bone marrow smears in seven children with systemic onset juvenile rheumatoid arthritis (JRA). Eosinophilia and monocytosis were found in all the patients and in five there also were increased proportions of mononuclear basophils. Anemia is common in this disease and erythroid hypoplasia was present in six cases. Four patients had increased numbers of plasma cells and three had histiocytes with hemophagocytic activity. We did not find hemophagocytosis, as reported before, in bone marrow smears of JRA patients.
开展了一项回顾性研究，以评估7例全身型幼年类风湿性关节炎（JRA）患儿的骨髓涂片。所有患者均发现嗜酸性粒细胞增多和单核细胞增多，5例患者的单核嗜碱性粒细胞比例也有所增加。贫血在该疾病中很常见，6例存在红系造血低下。4例患者的浆细胞数量增加，3例有具有噬血细胞活性的组织细胞。我们在JRA患者的骨髓涂片中未发现如之前报道的噬血细胞现象。
