Eosinophilia predicts better overall survival after acute graft-versus-host-disease.
The prognostic significance of eosinophilia after allogeneic hematopoietic SCT (HSCT) and the relationship between eosinophilia and acute GVHD are not well studied. We retrospectively analyzed 201 adult patients who underwent their first allogeneic HSCT. Seventy-three (36%) patients developed eosinophilia within the first 100 days after HSCT. ⋯ In contrast, eosinophilia was not associated with outcomes in those patients without acute GVHD. In conclusion, eosinophilia was associated with milder acute GVHD and better prognosis among patients with acute GVHD. The pathophysiology behind eosinophilia after allogeneic HSCT remains to be investigated.

Multicenter StudyUnrelated umbilical cord blood transplantation in children with immune deficiency: results of a multicenter study.
In the absence of a related donor, unrelated cord blood transplant (CBT) may be a potential option for patients with a primary immune deficiency (PID). Most published experience consists of single-center data using multiple preparative regimens and GVHD prophylaxis. We report the results of a multicenter prospective trial of unrelated CBT for PID. ⋯ Cumulative incidence estimates of grade III-IV acute GVHD at day 100 and chronic GVHD at 1 year were 29% (95% CI: 10-48%) and 24% (95% CI: 3-44%), respectively. The probability of survival at 180 days and 1 year was 66.7% (95% CI: 44.3-81.7%) and 62.5% (95% CI: 40.3-78.4%), respectively. Unrelated CBT should be considered in children with PID.
