Abstract
Engraftment syndrome (ES) is associated with neutrophil recovery after stem cell transplantation (SCT). It is associated with autologous and allogeneic SCT. However, a literature review has shown that allogeneic SCT (allo-SCT) is associated with ES without conclusive data on risk factors or effects on outcomes. This meta-analysis was undertaken to estimate the cumulative incidence of ES following allo-SCT, and to evaluate the risk factors and outcomes among patients with ES following allo-SCT. Current literature was searched using electronic databases, and manually. Studies with ES after allo-SCT were selected, and a meta-analysis of proportion was performed using the Freeman-Tukey Double Arcsine transformation, random-effects model to calculate the cumulative incidence of ES. Donor type, source of haematopoetic stem cells, graft vs. host disease (GvHD) prophylaxes, and conditioning regimens' intensity were evaluated for risk factors for ES. Association of acute GvHD (aGvHD), chronic GvHD (cGvHD), relapse, nonrelapse mortality (NRM), and overall survival (OS) between the ES and no ES groups were assessed using the odds ratio (OR). Eighteen studies were included comprising 3620 patients receiving allo-SCT and 774 of them had developed ES with a cumulative incidence of 35.4%. The odds of aGvHD (OR 2.5, p < 0.001), cGvHD (OR 4.5, p = 0.021), and NRM (OR 1.8, p = 0.01) were higher among patients who developed ES. The odds of relapse were significantly less (OR = 0.679, p = 0.011) among the ES group. OS (OR = 0.72, p < 0.001) was reduced in the ES group. Myeloablative conditioning was found to be a significant risk factor for ES development. In conclusion, ES after allo-SCT is common with higher odds of developing aGvHD, cGvHD, and NRM and lower odds of OS.

Abstract
BACKGROUND Diagnosis of engraftment syndrome (ES) following allogeneic hematopoietic stem cell transplantation (HSCT) can be a challenge due to the systemic presentation and alternative etiologies. With a goal of establishing biomarkers to more accurately distinguish ES, we prospectively analyzed levels of cytokines during HSCT. PROCEDURES We performed a prospective study of children <=21 years who underwent allogeneic HSCT. Blood samples for interleukin (IL)-6, IL-8, IL-10, IL-1b, IL-12p70, interferon-gamma, tumor necrosis factor alpha (TNF-alpha) and procalcitonin were obtained from each subject prior to conditioning, at day 0, and then biweekly through engraftment and at days 30, 60 and 100. Patients were evaluated for ES, infection and acute graft-versus-host disease. Cytokines were analyzed by values at engraftment, and also compared to pre-conditioning and day 0 values to evaluate for change from baseline. RESULTS A total of 30 subjects (median age: 7 years, min.-max.: 1-21 years) were enrolled of whom 5 had ES. Characterization of the cytokine profile revealed differences between day 0 from pre-HSCT, with a trend towards differences in IL-10, IL-12p70, interferon-gamma and TNF-alpha at the time of ES. For IL8 and procalcitonin, there was evidence that the absolute difference (or fold change) between engraftment and pre-conditioning or day 0 differed according to ES. In particular, procalcitonin increased from baseline (15.1 median fold increase in ES+ versus 2.31 median fold increase in ES-, P = 0.0006, median difference: 13.8, 95% confidence interval: 6.33, 65.6). CONCLUSIONS Our data provide one of the first prospective studies evaluating cytokines in pediatric allogeneic HSCT and suggest that elevated procalcitonin may serve as a biomarker for ES. Further studies to evaluate this finding are warranted.

Abstract
The biology of engraftment syndrome is poorly understood, and the degree of overlap with acute graft-versus-host disease (GVHD) is unclear. To understand engraftment syndrome better, plasma cytokine profiles were evaluated in 56 pediatric allogeneic bone marrow transplant recipients before transplant, on the day of stem cell infusion, and weekly until day +100. Patients were divided into 4 groups: those with isolated engraftment syndrome (n = 8), acute GVHD (n = 12), both engraftment syndrome and acute GVHD (n = 4), and neither engraftment syndrome nor acute GVHD (n = 32). Engraftment syndrome was observed a median of 13.5 days (range, 10 to 28) after transplant, whereas acute GVHD was diagnosed a median of 55 days (range, 19 to 95) after transplant. Four patients developed both engraftment syndrome at a median of 10.5 days (range, 10 to 11) and acute GVHD at a median of 35 days (range, 23 to 56) after stem cell infusion. Median plasma levels of IL-1beta, IL-6, IL-12, IL-4, and IL-13 were significantly elevated in patients with isolated engraftment syndrome when compared with isolated acute GVHD. A rise of proinflammatory cytokines (IL-1beta, IL-6, and IL-12) was followed by surge in anti-inflammatory cytokines (IL-4 and IL-13) in patients with isolated engraftment syndrome. The observation of elevated IL-1beta suggests that engraftment syndrome could be an inflammasome mediated phenomenon. Copyright © 2016 American Society for Blood and Marrow Transplantation.

Abstract
Pre-engraftment syndrome (PES) after umbilical cord blood transplantation (CBT) remains poorly characterized, and the prognosis and appropriate management are unclear. Therefore, we retrospectively analyzed the incidence, risk factors, manifestations, and clinical outcomes of PES in CBT recipients, who had been treated for hematologic malignancies at our transplantation center. PES was defined as unexplained fever higher than 38.3degreeC that is not associated with documented infection and unresponsive to antimicrobial manipulations and/or unexplained erythematous skin rash occurring prior to neutrophil engraftment. A total of 81 patients (median 18 yr, range 3-48) received either myeloablative (n=72) or non-myeloablative (n=9) conditioning. Neutrophil engraftment was achieved in 69 of the 81 cases [86.2%, 95% confidence interval (CI)=78.9-94.1%], and the median time to more than 0.5 x 10(9) /L ANC was 19 d (range, 12-39). Fifty-one patients (63.0%) developed PES at a median of 7d (range 3-15) post-transplant: 46 patients had both rash and unexplained fever; one patient had unexplained fever alone; and four patients had rash only. Forty-seven patients (92.2%) received IV methylprednisolone (MP) at a median dose of 1 mg/kg (range 0.4-3). All patients treated with MP responded as evidenced by fever resolution combined with resolution of rash. All patients with PES had high serum levels of C-reactive protein (CRP), which were significantly reduced after effective steroid treatment. Univariate analysis identified myeloablative conditioning and younger age as significant risk factors for developing PES. Cumulative incidence of grade II-IV acute graft-versus-host disease (aGVHD) in the PES+ and PES- groups was 51.5% (95% CI=38.0-70.0%) and 17.0% (95% CI=6.9-41.7%), respectively. In a multivariate analysis, we found significantly increased risk of grade II-IV aGVHD among PES patients (P=0.041). However, PES was not associated with sustained donor engraftment, the day to neutrophil recovery, chronic graft-versus-host disease, transplant-related mortality at day 180, and overall survival. Despite of the inherent limitations of this small retrospective study, PES seemed to be common after CBT and associated with high incidence of aGVHD.Copyright © 2011 John Wiley & Sons A/S.
