Large-scale HEV genotype 3 outbreak on New Caledonia Island.

Background And Aims: Several symptomatic cases of HEV infections were reported to the New Caledonia Island Public Health Service between August and December 2023. This prompted epidemiological and virological investigations to identify the source of infection.

Approach And Results: HEV RNA was assessed in symptomatic patients, various food items, and pig farms on the Island.

Favorable Outcome of an Exclusively Posttransplant Prophylactic Strategy After Heart Transplantation in Recipients With High Immunological Risk.

Background: Management of the increasing number of sensitized heart transplant candidates has become a recurrent issue. Rather than using pretransplant desensitization therapies, we used a posttransplant prophylactic strategy. Our aim was to describe outcomes in transplant recipients with preformed donor-specific anti-HLA antibodies (pfDSA) managed with this strategy.

Severe hemolysis after plasma transfusion in a neonate with necrotizing enterocolitis, Clostridium perfringens infection, and red blood cell T-polyagglutination.

Background: Red blood cell (RBC) Thomsen-Friedenreich antigen exposure (T activation) in infants with necrotizing enterocolitis (NEC) has occasionally been associated with posttransfusional intravascular hemolysis thought to be due to anti-T antibodies in the donor plasma.

Study Design And Methods: We describe an infant with NEC and Clostridium perfringens infection complicated by severe hemolysis after plasma transfusion. After this case, infants with confirmed NEC were prospectively evaluated for T activation.

Immunohematologic tolerance of chronic transfusion exchanges with erythrocytapheresis in sickle cell disease.

Background: Sickle cell disease (SCD) has become a major public health issue. Hydroxyurea and red blood cell (RBC) transfusion are the cornerstone treatments. Erythrocytapheresis (ECP) is an automated method for transfusion exchange.
