Dynamic Differences Of Red Cell Distribution Width Levels Contribute To The Differential Diagnosis Of Hepatitis B Virus-related Chronic Liver Diseases: A Case-control Study
Department of Clinical Laboratory, Peking University People's Hospital, Beijing, China
Objective: This study aims to clarify the changes and clinical significance of red cell distribution width (RDW) during HBV-related chronic diseases, including inactive hepatitis B virus (HBV) carriers, HBV immune tolerant individuals, chronic hepatitis B (CHB) patients and HBV-related hepatocirrhosis patients.
Methods: RDW was measured 288 CHB patients, 100 patients with hepatitis B e antigen(HBeAg)-negative chronic HBV infection (inactive carriers), 92 patients with HBeAg-positive chronic HBV infection (immune tolerant), and 272 patients with HBV-related hepatocirrhosis. Their RDW changes were compared with 160 healthy controls. Correlations between RDW and clinical indicators were conducted. For HBeAg+ CHB patients, RDW was measured before and after antiviral therapy. The efficiency of RDW to distinguish hepatocirrhosis from CHB and/or inactive carriers was evaluated by receiver operating characteristic (ROC) curves.
Results: RDW was higher in hepatocirrhosis patients than other groups of patients and healthy controls. Besides, HBeAg+ CHB patients possessed higher RDW than HBeAg- CHB patients. For HBeAg+ patients that underwent HBeAg seroconversion after antiviral therapy, RDW was decreased. RDW was positively correlated with total bilirubin and Child-Pugh scores and negatively correlated with albumin among hepatocirrhosis patients. The areas under the curve (AUC) of ROC curves to distinguish hepatocirrhosis from CHB patients was 0.7040 for RDW-standard deviation (RDW-SD) and 0.6650 for RDW-coefficient of variation (RDW-CV), and AUC to distinguish hepatocirrhosis from inactive carriers was 0.7805 for RDW-SD and 0.7991 for RDW-CV.
Conclusions: RDW is significantly increased in HBeAg+ CHB patients and patients with HBV-related hepatocirrhosis and could reflect their severity. RDW could help to distinguish hepatocirrhosis from CHB patients and inactive HBV carriers.
