红细胞分布宽度与肝脏疾病的关系

Research progress on the relationship between red cell distribution width and liver disease

红细胞分布宽度（RDW）是红细胞异质性的客观指标，反映了红细胞大小不均一性。RDW升高与许多疾病相关，特别是心血管疾病，而与肝脏疾病的关系研究主要集中于与慢性HBV感染相关的疾病和非酒精性脂肪性肝病纤维化程度以及疾病严重程度的相关性上。此文就RDW与上述肝脏疾病相关性研究的进展进行综述。

Red cell distribution width （RDW） is an objective indicator of red blood cell （RBC） heterogeneity which reflects size variability of RBC. Rise of RDW associates many disease, especially with cardiovascular disease. The association of RDW and liver disease focuses on the relationship with severity of HBV-associated liver disease and nonalcoholic fatty liver disease and with stage of liver fibrosis. Research progresses on these aspects are reviewed in this paper.
