Definitions, incidence and outcome of poor graft function after hematopoietic cell transplantation: A systematic review and meta-analysis. Blood Rev 2023; 60:101076.

Abstract
Poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (HCT) is a serious complication with high morbidity and mortality. The reported incidence of PGF, its risk factors and outcome vary substantially between studies. This variability may be explained by heterogeneity in patient cohorts and HCT strategies, differences in the underlying causes of cytopenia, as well as by differences in PGF definition. In this systematic review and meta-analysis, we provide an overview of the various PGF definitions used and determined the impact of this variability on the reported incidence and outcome. We searched MEDLINE, EMBASE and Web of Science up to July 2022, for any study on PGF in HCT recipients. We performed random-effect meta-analyses for incidence and outcome and subgroup analyses based on different PGF criteria. Among 69 included studies (14.265 HCT recipients), we found 63 different PGF definitions, using various combinations of 11 common criteria. The median incidence of PGF was 7% (IQR: 5-11%, 22 cohorts). The pooled survival of PGF patients was 53% (95% CI: 45-61%, 23 cohorts). The most commonly reported risk factors associated with PGF were history of cytomegalovirus infection and prior graft-versus-host disease. Incidence was lower in studies with strict cytopenic cutoffs, while survival was lower for primary compared to secondary PGF. This work indicates that a standardized, quantitative definition of PGF is needed to facilitate clinical guideline development and to advance scientific progress.

Abstract
RATIONALE Poor graft function (PGF) occurs in 5% to 27% of allogeneic hematopoietic stem cell transplantation (allo-HSCT) and is associated with high life-threatening complications. The etiology of PGF is complex and multifactorial, and iron overload (IOL) is considered as a predictive factor. PATIENT CONCERN A 45-years-old woman who was diagnosed as low-risk myelodysplastic syndrome in 2012 has been transfusion dependent and developed severe IOL. DIAGNOSES Due to transfusion dependency and also ineffective erythropoiesis, this patient was diagnosed as IOL and developed PGF after allo-HSCT. INTERVENTIONS Deferasirox (20mg/kg/d) was administered regularly after allo-HSCT for 2 years. OUTCOMES Hematopoiesis was gradually recovered during iron chelation therapy treatment after allo-HSCT and PGF was reverted. LESSONS IOL, as a prognostic factor for PGF, is a common problem in Transfusion dependent myelodysplastic syndrome patients undergoing HSCT. IOL issues should be considered at the time of diagnosis and throughout the treatment course for patients who are potential candidates for HSCT.

Abstract
Many patients with hematologic malignancies receive RBC transfusion support, which often causes systemic and tissue iron toxicity. Because of their compromised bone marrow function, hematopoietic stem cell transplant (HSCT) recipients are especially vulnerable to excess iron levels. Iron toxicity may compromise transplant engraftment and eventually promote relapse by mediating oxidative and genotoxic stress in hematopoietic stem cells (HSCs) and further impairing the already dysfunctional bone marrow microenvironment in HSCT recipients. Iron toxicity is thought to be primarily mediated by its ability to induce reactive oxygen species and trigger inflammation. Elevated iron levels in the bone marrow can decrease the number of HSCs and progenitor cells, as well as their clonogenic potential, alter mesenchymal stem cell differentiation, and inhibit the expression of chemokines and adhesion molecules involved in hematopoiesis. In vivo, in vitro, and clinical studies support the concept that iron chelation therapy may limit iron toxicity in the bone marrow and promote hematologic improvement and engraftment in HSCT recipients. This review will provide an overview of the current knowledge of the detrimental impact of iron toxicity in the setting of HSCT in patients with hematologic malignancies and the use of iron restriction approaches to improve transplant outcome.

Ther Adv Hematol 2020; 11:2040620720961910. [PMID: 33194161 PMCID: PMC7594218 DOI: 10.1177/2040620720961910] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/03/2020] [Accepted: 09/07/2020] [Indexed: 12/12/2022] Open
Abstract
Background: Patients with post-transplant cytopenias due to poor graft function or
primary engraftment failure show poor prognosis with a high mortality rate
mainly because of graft versus host disease (GVHD),
infection and/or bleeding. Treatment options are scarce and a CD34+ stem
cell boost or a second bone marrow transplantation may be required to
restore adequate haematopoiesis. Methods: In the present study patients with primary engraftment failure
(n = 1) and refractory poor graft function
(n = 11) were treated with eltrombopag in a single
centre. The reason for eltrombopag treatment was trilineage cytopenia in six
patients, bilineage cytopenia in three patients and single lineage cytopenia
in three patients. Eltrombopag was initiated at a median of 214 (range:
120–877) days after haematopoietic stem cell transplantation (HCST) and
administered for a median time of 114 (range: 12 days to >490) days. In
8/12 patients eltrombopag was introduced at a dose of 75 mg/day and then
increased to 150 mg/day after 1 week; 1 patient was given 50 mg eltrombopag
per day, and 3 patients received 75 mg daily. Results: In 10/12 patients eltrombopag significantly enhanced blood count values and
patients became transfusion independent. Once stable haematological response
was obtained, treatment was tapered until final discontinuation in 9/10
responding patients. No grade 3 or 4 toxicities were observed. At time of
last follow up, 3/12 patients were dead, 2 due to disease relapse, 1 due to
GVHD and pneumonia. All patients except one maintained their complete
response and remain transfusion independent at a median of 858 (range:
429–1119) days. Conclusion: These preliminary data confirm that eltrombopag is able to rescue
multilineage haematopoiesis in patients with treatment-refractory cytopenias
after allogeneic HSCT.

Abstract
Poor graft function (PGF) following allogeneic hematopoietic stem-cell transplantation (allo-HSCT) is a life-threatening complication and is characterized by bilineage or trilineage blood cell deficiency and hypoplastic marrow with full chimerism. With the rapid development of allo-HSCT, especially haploidentical-HSCT, PGF has become a growing concern. The most common risk factors illustrated by recent studies include low dose of infused CD34+ cells, donor-specific antibody, cytomegalovirus infection, graft versus host disease (GVHD), iron overload and splenomegaly, among others. Because of the poor prognosis of PGF, it is crucial to uncover the underlying mechanism, which remains elusive. Recent studies have suggested that the bone marrow microenvironment may play an important role in the pathogenesis of PGF. Deficiency and dysfunction of endothelial cells and mesenchymal stem cells, elevated reactive oxygen species (ROS) levels, and immune abnormalities are believed to contribute to PGF. In this review, we also discuss recent clinical trials that evaluate the safety and efficacy of new strategies in patients with PGF. CD34+-selected stem-cell boost (SCB) is effective with an acceptable incidence of GVHD, despite the need for a second donation. Alternative strategies including the applications of mesenchymal stem cells, N-acetyl-l-cysteine (NAC), and eltrombopag have shown favorable outcomes, but further large-scale studies are needed due to the small sample sizes of the recent clinical trials.

Abstract
Objective: To investigate the risk factors of poor graft function (PGF) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) for severe aplastic anemia (SAA) . Methods: Clinical data from 111 SAA patients who received allo-HSCT were analyzed retrospectively. Factors including age, gender, interval to transplantation, the level of serum ferritin before transplantation were analyzed by Cox multivariate regression analysis. Results: Among the 111 patients who underwent allo-HSCT, 16 developed PGF (14.4%) . Multivariate analysis showed donor type (HR=2.656, 95%CI 1.204-5.858, P= 0.016) and the level of serum ferritin before tansplantation (HR=3.170, 95%CI 1.400-7.180, P=0.006) were significant risk factors for PGF. Conclusion: Unrelated donor transplantation and the high level of serum ferritin before transplantation are risk factors for PGF.
