The public health implications of hepatitis E virus (HEV) in Europe have changed due to increasing numbers of hepatitis E cases and recent reports of chronic, persistent HEV infections associated with progression to cirrhosis in immunosuppressed patients. The main infectious risk for such immunosuppressed patients is exposure to undercooked infected pork products and blood transfusion. We summa...
Background and Aims: This study was the trends of Hepatitis B infection among Iranian blood donors which was analyzed in a period of 10 years. Materials and Methods: In a period of 10 years, from 2001 through 2010, a total of 16,264,830 donations from 30 regional and 35 local blood services were screened. All blood samples were tested for Hepatitis B surface antigen (HBs Ag) by commercial avail...
The Public Health Service (PHS) has recommended a multifaceted approach to blood safety in the United States that includes stringent donor selection practices and the use of screening tests. Blood donations in the United States have been screened for antibody to human immunodeficiency virus type 1 (HIV-1) since March 1985 and type 2 (HIV-2) since June 1992. An estimated one in 450,000 to one in...
BACKGROUND Blood donations resulting in "nontransparent turbid milky" plasma must be discarded. The aim of this study was to objectively determine opacity and to identify risk factors for turbid plasma donations. STUDY DESIGN AND METHODS This case-control study included 238 whole blood donors who provided turbid plasma (cases) and 309 random control subjects with normal plasma. Participants f...
OBJECTIVES Infection remains a leading cause of post-transfusion mortality and morbidity. Bacterial contamination is, however, detected in less than 0.1% of blood units tested. The aim of the study was to identify viable bacteria in standard blood-pack units, with particular focus on bacteria from the oral cavity, and to determine the distribution of bacteria revealed in plasma and in the red b...
The prevalence of HBV DNA among seronegative blood donations in China has not been studied extensively on a nationwide scale. The aim of this study was to analyse the prevalence, trend, distributions, and serological characteristics of HBV DNA positive/seronegative blood donations. We collected HBV test data from all blood banks of China from 2010 to 2015 and performed supplemental serological ...
BACKGROUND In experimental animals, iron overload appears to promote atherosclerosis and ischemic myocardial damage, but the results of epidemiological studies that relate iron stores to risk of coronary heart disease (CHD) have been inconsistent. METHODS AND RESULTS We prospectively studied blood donations, which effectively reduce body iron stores, in relation to the risk of CHD among parti...
