autoimmunity and viral infections are closely associated fields, and viruses have been proposed as a likely aetiological, contributory or triggering factors of systemic autoimmune diseases. hepatitis c virus seems to be the virus usually associated with the appearance of autoimmune diseases, and the relationship between chronic hepatitis c virus infection and some autoimmune disease has been st...

background: hepatitis g virus (gbv-c) is a single strand rnapositive virus and is a member of flaviviridae family. infection with the virus is prevalent add has worldwide distribution. accurate diagnosis of the virus is very important, because of co-infection with other important viruses like hcv, hbv and hiv, it may influence on pathogenesis, disease progression and response to viral therapy. ...

transfusion-transmissible infections such as hepatitis b and hepatitis c are among the greatest threats to blood safety for transfusion recipients and pose a serious public health problem. the aim of this study was to assess the epidemiological aspects of hepatitis b and c in kazakhstani donor's blood over the period 2000-2011.the data were obtained from the annual reports of the republican blo...

conclusions history of drug addiction and/or blood transfusion and longer duration of hd treatment were the main risk factors determining the prevalence of hcv infection in the hormozgan province of southern iran in 2015. however, the values observed in the present investigation reflect the effective management techniques imposed by healthcare authorities and relevant organizations in recent ye...

Background and Aims: Evaluation of the prevalence of transfusion-transmissible infections (TTIs) in blood donors is a valuable index of donor selection and blood safety. This study was conducted to explore the prevalence and trends of TTIs markers and study of confidential unit exclusion )CUE) option among blood donors in Kurdistan province in the west of Iran. Materials and Methods: We conduc...
