We aimed to study whether red blood cell distribution width (RDW) could be one of the variables determining the extent of liver fibrosis and inflammation in patients with biopsy-proven hepatitis B. A total of 446 hepatitis B virus-infected patients who underwent liver biopsy were divided into 2 groups: absent or mild and moderate-severe according to the severity of liver fibrosis and inflammation. The independent variables that determine the severity of liver fibrosis and inflammation were explored. RDW values increased with progressive liver fibrosis and inflammation...

OBJECTIVE: To evaluate the effect of the viral load on the red blood cell parameters in chronic hepatitis B patients and its clinical significance. METHODS: In the study, 373 chronic hepatitis B patients were recruited, including 123 alanine transaminase (ALT) normal patients (ALT<40 U/L),128 ALT greater than or equal to the upper limit of normal, and less than 2 times higher than the upper limit of normal patients(40 U/L ≤ALT<80 U/L), and 122 ALT greater than or equal to 2 times higher than the upper limit of normal patients (ALT≥80 U/L)...

OBJECTIVE: Hepatitis B virus infection is still one of the leading causes of cirrhosis and hepatocellular carcinoma worldwide. Liver biopsy is the gold-standard method to assess the severity of liver fibrosis, but the invasive nature of this method limits its usage. Currently, noninvasive parameters are utilized to estimate liver histology. In the present study, we aimed to investigate the relationship between the severity of fibrosis and red blood cell distribution width (RDW), platelet distribution width (PDW), mean platelet volume (MPV), and MPV and red blood cell distribution width to platelet ratio (RPR) in patients with chronic hepatitis B (CHB)...

BACKGROUND: Sensitivity data from a head-to-head comparison study in South Africa were used to compare the efficacy of the Ultrio Plus assay in individual-donation (ID) and minipool (MP)4 and MP8 formats with that of TaqScreen MP6 in preventing hepatitis B virus (HBV) transmission risk. STUDY DESIGN AND METHODS: The replicate nucleic acid test (NAT) results on 106 HBV NAT (Ultrio)-yield samples and 29 HBV DNA (Ultrio)-negative, hepatitis B surface antigen (HBsAg)-positive samples were used to determine the viral load in copies/mL against the Eurohep HBV standard by probit analysis...

OBJECTIVE: To develop a simple predictive model for significant fibrosis and cirrhosis in chronic hepatitis B (CHB) using the routine hematological parameters of a complete blood count. METHODS: A total of 458 eligible CHB patients who had undergone a liver biopsy were randomly divided into two cohorts: an estimation group (n = 310) and a validation group (n = 148). Liver histology was assessed according to the Metavir scoring scheme. All common demographics, hematological parameters, HBeAg status, HBV DNA, and liver biochemistry were analyzed...

BACKGROUND: Red blood cell distribution width (RDW) is increased in liver disease. Its clinical significance, however, remains largely unknown. The aim of this study was to identify whether RDW was a prognostic index for liver disease. METHODS: We studied, retrospectively, 33 patients with non-cirrhotic HBV chronic hepatitis, 125 patients with liver cirrhosis after HBV infection, 81 newly diagnosed primary hepatocellular carcinoma (pHCC) patients, 17 alcoholic liver cirrhosis patients and 42 patients with primary biliary cirrhosis (PBC)...

BACKGROUND: Red blood cell distribution width (RDW), an automated measure of red blood cell size heterogeneity (e.g., anisocytosis) that is largely overlooked, is a newly recognized risk marker in patients with cardiovascular diseases, but its role in persistent viral infection has not been well-defined. The present study was designed to investigate the association between RDW values and different disease states in hepatitis B virus (HBV)-infected patients. In addition, we analyzed whether RDW is associated with mortality in the HBV-infected patients...

OBJECTIVE: To investigate the expression and distribution of Toll-like receptor 4 (TLR4) in renal tissue of HBV associated nephropathy (HBV-GN) and its role in the pathogenesis and clinical manifestations of HBV-GN. METHODS: Renal tissues were sampled from 48 HBV-GN patients confirmed by renal biopsy and 154 non-HBV-GN patients. The distribution of TLR4 in renal tissue and the relationship between the distribution of TLR4 and HBsAg were detected by immunohistochemistry...

BACKGROUND/AIMS: To identify risk factors of postoperative ascites after hepatectomy for patients with hepatocellular carcinoma (HCC) and hepatitis B virus associated-cirrhosis. METHODOLOGY: The data of 73 patients were reviewed in current study. Pre- and intra-operative variables were retrospectively analyzed using uni- and multi-variate analyses. The diagnostic accuracy of the predictors was evaluated by the receiver operating characteristics (ROC) analysis. RESULTS: Indocyanine green retention rate at 15 minutes (ICGR15) >10%, tumor size >10cm, splenectomy, middle hepatic vein (MHV) resection, red blood cell (RBC) transfusion were risk factors in univariate analysis...

BACKGROUND: The number of apheresis collections increased significantly in recent years; however, data on viral marker rates among these collections are lacking. STUDY DESIGN AND METHODS: Apheresis collection data for 2004 to 2008 were analyzed. All collections were tested for antibodies and viral RNA for human immunodeficiency virus (HIV) and hepatitis C virus (HCV), hepatitis B surface antigen (HBsAg), antibody to hepatitis B core antigen (anti-HBc), antibody to human T-lymphotropic virus (anti-HTLV), and other markers...

Phospholipid vesicles encapsulating concentrated human hemoglobin (Hb-vesicles, HbV), also known as liposomes, have a membrane structure similar to that of red blood cells (RBCs). These vesicles circulate in the bloodstream as an oxygen carrier, and their circulatory half-life times (t(1/2)) and biodistribution are fundamental characteristics required for representation of their efficacy and safety as a RBC substitute. Herein, we report the pharmacokinetics of HbV and empty vesicles (EV) that do not contain Hb, in rats and rabbits to evaluate the potential of HbV as a RBC substitute...

Lyophilized PHP as an oxygen carrier is prepared from outdated red cell and dicarboxymethylated polyoxyethylene. In order to apply PHP for a clinical use, a large scale production of high quality PHP has been studied. We have set up a 20 L scale production flow of PHP88. The product was tested to confirm the quality and lot-to-lot consistency. The blood group specific materials were weakly positive in stroma-free hemoglobin (SFH), however, were found negative in the PHP of this scale. The amount of phosphatidylethanolamine (PE) in purified SFH and PHP88 reconstituted solution was 0...
