Title: Graft-versus-host disease (GVHD) prophylaxis by using methotrexate decreases pre-engraftment syndrome and severe acute GVHD, and accelerates engraftment after cord blood transplantation. Author: Iguchi A, Terashita Y, Sugiyama M, Ohshima J, Sato TZ, Cho Y, Kobayashi R, Ariga T. Journal: Pediatr Transplant; 2016 Feb; 20(1):114-9. PubMed ID: 26526424. Abstract: GVHD and graft failure are serious problems in CBT. PES after CBT also occurs frequently and is associated with transplantation-related complications such as acute GVHD. We reviewed medical records for 70 consecutive child CBT recipients between December 1997 and April 2015. Forty-nine patients received prophylaxis against GVHD with CsA or Tac in combination with mPSL from day +7 (mPSL group), and 21 patients received CsA or Tac with MTX on day +1 and day +3 (MTX group). Neutrophil engraftment was detected in 59 patients (84.3%). Neutrophil engraftment rate in the MTX group was significantly higher than that in the mPSL group (21/21 (100%) and 38/49 (77.6%), respectively, p = 0.027). PES developed in 35 patients, and the incidence of PES in the mPSL group was significantly higher than that in the MTX group (p = 0.036). The incidence of severe acute GVHD (grade III or IV) in the MTX group was significantly lower than that in the mPSL group (p = 0.049). Although this study was a small-scale study, the results showed that increase in the rate of engraftment and decrease in the incidence of early immune reactions such as PES and severe acute GVHD could be achieved by early commencement of immunosuppression using MTX.[Abstract] [Full Text] [Related] [New Search]
