High prevalence of anti-hepatitis E virus antibodies in blood donors from South West France.

Cases of autochthonous acute hepatitis E occur in most industrialized countries and are frequent in the South West of France. The prevalence of anti-hepatitis E virus (HEV) IgG antibodies in blood donors in this area was determined. A total of 529 samples from rural and urban blood donors were tested.

Local immunotherapy of recurrent glioblastoma multiforme by intracerebral perfusion of interleukin-2 and LAK cells.

A non randomized pilot study has been undertaken to evaluate the feasibility of local immunotherapy (IT) of recurrent glioblastoma multiforme (GM) by continuous intracerebral perfusion of recombinant interleukin-2 (rIL-2, Eurocetus) with and without lymphokine activated killer (LAK) cells. At time of surgical removal of the tumor, a catheter was implanted in the cavity left by tumor debulking allowing continuous perfusion of rIL-2. Five patients received 18 x 10(6) IU/day or rIL-2 for five days.

Risk factors for cytomegalovirus infection in BMT recipients transfused exclusively with seronegative blood products.

Risk factors for developing cytomegalovirus (CMV) infection and pneumonitis were analysed in 100 unselected consecutive patients undergoing allogenic BMT. This series is homogeneous because of the same diagnostic procedures, BMT technique and supportive care (exclusive seronegative blood products, no CMV immunoglobulin, no prophylactic antiviral). The incidence of CMV infection and CMV interstitial pneumonitis (CMV-IP) were 44% and 13% respectively, of whom five patients died.
