Posttransfusion hepatitis after exclusion of commercial and hepatitis-B antigen-positive donors.
In a prospective study the exclusion of commercial blood donors and donors positive for hepatitis-B antigen (HBAg) resulted in a hepatitis frequency of only 3 .7 cases/1000 units transfused. Residual posttransfusion hepatitis was caused by at least two viruses. Four of 10 cases were short incubation, HBAg negative; six cases were long incubation, HBAg positive. One patient had both diseases in ...
متن کاملHistory of posttransfusion hepatitis.
The risk of hepatitis virus transmission from tranfusions has declined dramatically from that of the 1940s when posttransfusion hepatitis (PTH) was first appreciated. Introduction of hepatitis B surface antigen screening and conversion to volunteer donors for whole-blood donations in the late 1960s and early 1970s led to substantial reduction in PTH cases. However, up to 10% of the recipients c...
متن کاملEXPRESSION OF HEPATITIS B SURFACE ANTIGEN IN SACCHAROMYCES CEREVISIAE
The genome of HB V virus of serotype ayw cloned in pBR322 and expression shuttle vector p YES2 were used for construction of the HBsAg chimeric genes and their expression in Saccharomyces cerevisiae. Two recombinant plasmids were constructed. One of them contained the coding sequences for the major polypeptide of surface antigen. Another construct carried the major polypeptide with the pre-S2 a...

متن کاملSerum hepatitis C virus sequences in posttransfusion non-A, non-B hepatitis.
We investigated 17 patients (12 males and 5 females, ages 2 to 57 years old) with posttransfusion non-A, non-B hepatitis to determine relationships between clinical courses and hepatitis C virus (HCV) markers. The patients were grouped according to time course of abnormal serum alanine aminotransferase (ALT) levels into three categories (chronic biochemical disease, biochemically resolved chron...
