Gastrointestinal graft-versus-host disease is a risk factor for post-engraftment blood stream infection in allogeneic hematopoietic stem cell transplant recipients

Blood stream infection (BSI) is a common complication in patients after allogeneic hematopoietic stem cell transplantation (allo-HSCT) and can be fatal without appropriate and expedient treatment, especially in the pre-engraftment period [1 –3]. Intensive chemotherapy and irradiation allows bacteria to enter the systemic circulation via disrupted mucosal barriers of the gastrointestinal (GI)-tract and/or oral cavity, providing an inflammatory cytokine milieu fit for T-cell proliferation and activation, This culminates in the developm ent of acute graft-versus-host disease (GvHD) after the engraftment of donor cells [4].
