Abstract

aGVHD of the GI tract is common after allogeneic HSCT. Corticosteroids are the mainstay of treatment. Recent data suggest infliximab might be beneficial for steroid refractory aGVHD. We reviewed our experience in 10 pediatric patients who developed severe steroid refractory aGVHD (stage 3, n = 6; stage 4, n = 4), after an allogeneic matched unrelated HSCT for various hematological diseases (leukemia, n = 7; thalassemia, n = 3). The median age was 9.5 yr (range, 0.8-18.5 yr). All patients received 10 mg/kg infliximab weekly for 3-4 doses. Eight patients had CR and two had partial response. None of the patients developed therapy-related adverse effects. All patients developed infections subsequently, which may or may not be related to infliximab. Five patients developed chronic GVHD (cGVHD) (four severe, one mild). Six patients died at 66-1451 days post-transplant, from infection (n = 3), aGVHD (n = 1), lung cGVHD (n = 1), or idiopathic pneumonia (n = 1). Four patients were alive at 238-924 days post-transplant, all of whom had an increase in BMI by six months post-transplant. In conclusion, infliximab is well tolerated and appears effective in children with steroid refractory or dependent GI aGVHD. Infection is common and mortality remains high.
