Engraftment syndrome(ES)is one of the most common complications in the early phase after autologous hematopoietic stem cell transplantation(ASCT),and we aimed to evaluate the incidence and risk factors for ES patients receiving ASCT in the era of plerixafor-based mobilization.A total of 294 were enrolled,and 16.0%(n=47)experienced ES after *** main clinical manifestations were fever(100%),diarrhea(78.7%),skin rash(23.4%),and hypoxemia/pulmonary edema(12.8%).Plerixafor-based mobilization was associated with higher counts of CD3^(+)cells,CD4^(+)cells,and CD8^(+)cells in *** univariate analysis of the total cohort,age≥60 years,receiving ASCT at complete remission(CR),higher number of mononuclear cell(MNC),CD3^(+)cell counts,CD4^(+)cells as well as CD8^(+)cells transfused and plerixafor-based mobilization were associated with ES after *** analysis showed that age≥60 years(P=0.0014),receiving ASCT at CR(P=0.002),and higher number of MNC transfused(P=0.026)were associated with ES in total *** plasma cell disease subgroup,age≥60 years(P=0.013),plerixafor-based mobilization(P=0.036),and receiving ASCT at CR(P=0.002)were associated with *** with more risk factors had a higher risk of *** 1-year probabilities of relapse,non-relapse mortality,and survival were comparable between patients with and without ***,plerixafor-based mobilization may influence the composition of T lymphocytes in grafts and increase the risk of ES,particularly in patients with plasma cell disease.

AIM:To clarify the endoscopic and clinical findings of cytomegalovirus(CMV) gastritis after allogeneic hematopoietic stem cell transplantation(allo-SCT).METHODS:Between 1999 and 2005,523 patients underwent allo-SCT at our hospital,and 115 of these patients with gastrointestinal symptoms underwent ***:CMV gastritis was diagnosed pathologically in seven patients(1.3%) with the other 108 patients serving as *** of the seven patients developed positive CMV antigenemia,and five complained of abdominal *** of abdominal pain preceded CMV antigenemia in four of the f ive *** examination showed oozing(n=2),erosion(n=6),and redness(n=5) in the seven patients with CMV gastritis,while the control patients showed oozing(n=3),erosion(n=24),and redness(n=100).Erosion and oozing were more frequently documented in patients with CMV gastritis compared with the controls,and the differences were statistically significant(P=0.0012 and 0.029,respectively).CMV inclusion bodies were documented in 12 of 14 biopsy specimens obtained from erosive lesions,while they were identif ied in 4 of 15 biopsy specimens obtained from lesions other than erosions(P=0.0025).CONCLUSION:This study suggests that erosion and oozing,as well as abdominal pain,are useful indicators in the diagnosis of CMV gastritis following allo-SCT.
