Abstract

  Abstract

 Background and Objectives

  The prevalence of GBV-C and HGV in blood donor populations in developd countries based on HGV RNA detection and anti-E2 screening ranges from 1 to 5 and 3 to 14% respectively. The aim of this study was to investigate seroepidemiologic hepatitis G virus (HGV) in blood donors, haemodialysis patients, haemophiliacs, and β thalassemics with a history of liver disease by Elisa tecnique.

 

  Materials and Methods

  In this descriptive study, blood samples of 330 volunteer blood donors, 44 haemodialysis patients, 16 haemophiliacs, and 40 β major thalassemics with a history of liver disease were studied by Elisa technique for their seroepidemiologic status of hepatitis G virus and their past record of HGV infection. For data analysis, Chi-square, Fisher exact test, and SPSS version 11.5 were used.

  

 Results

  This study showed that out of 330 healthy blood donors 14(4.2%), out of 44 haemodialysis patients 10(22.7%), out of 16 haemophiliacs 5 (30.3%) and out of 40 β thalassemics 10 (25%) were positive for HGV-anti-E2. These data are significant evidence for HGV to be considered as a transfusion-transmitted infection. The prevalence of anti-HGV and anti-HCV (co-infection) was found to involve 10 (30.3%) of haemodialysis patients, 4 (28.6%) of haemophiliacs and 9 (23.7%) of β thalassemics. It was also found that 1 (8.3%) of haemodialysis patients, 1 (33.3%) of haemophiliacs, and 1 (50%) of β thalassemics were infected with anti-HGV and HBsAg co-infection.

 

 Conclusions

  The prevalence of HGV was high in multitransfused individuals including haemodialysis patients, haemophiliacs, and thalassaemics. Therefore, HGV was a transfusion-transmittable agent. Co-infection of anti-HGV with HCV was observed in viruses. It is recommended that further studies focus on evaluating sexual and vertical transmission routes so as to cast light on relatively high rate of HGV in donor population.

Abstract
Abstract
Background and Objectives
ABO-incompatible allo-HSCT leads to complications like pure red cell aplasia (PRCA), which involves 7-16% of ABO-incompatible recipients. In this condition, albeit the development of other hematopoietic lineages in the bone marrow engraftment is successful, erythroid precursors are missing; thus, patients may require blood transfusions because of severe anemia. An extensive variety of treatment strategies has been introduced for treating PRCA patients. This study reviewed the various PRCA treatments following allo-HSCT.

Materials and Methods
In this Review study, keywords including Pure Red-Cell Aplasia, Hematopoietic Stem Cell Transplantation, and ABO Blood-Group System were searched in PubMed and Google Scholar databases. Sixty-four articles were reviewed, and related data were extracted.

Results
There are three main approaches for treating PRCA: erythropoiesis with erythropoietin, reducing isoagglutinin levels, and immunomodulatory therapies/graft versus plasma cell effect.

Conclusions 
Monoclonal antibody drugs targeting plasma cells have shown unprecedented results. Overall, PRCA management ways incorporate: individual patients’ evaluation in order to select the proper treatment management for each case, a thorough monitoring approach from the first day of hospitalization, and predicting the possibility of PRCA as indicated by blood group antibodies’ levels.
