Abstract
Iron overload (IOL) is a frequently reported complication following hematopoietic stem cell transplantation (HSCT) that has been investigated extensively in the field of hemoglobinopathies but has not been thoroughly characterized after HSCT in pediatric malignancies. Our aim was to assess prevalence, severity, risk factors, and management of IOL, as defined using biochemical (serum ferritin) and radiologic tools (T2*-weighted magnetic resonance imaging [MRI]), in a cohort of pediatric patients who underwent HSCT for either malignant or benign diseases. This monocentric, retrospective, observational study included all the 163 patients alive and in continuous remission at 24 months post-HSCT out of the 219 consecutive children and adolescents who underwent HSCT at our institution between 2012 and 2018, were included in the study. IOL was classified into 4 categories: absent, mild, moderate, and severe. Among the 163 patients, 73% had some degree of IOL (mild in 37%, moderate in 29%, and severe in 7%). Moderate/severe IOL was more frequent among patients diagnosed with a malignant disease versus those with a benign disease (43% versus 19%; P = .0065). Trend lines for serum ferritin showed a "bell-shaped" distribution, with the highest levels recorded during the first 6 months post-HSCT, followed by a spontaneous reduction. Both pre-HSCT (1659 ng/mL versus 617 ng/mL; P < .001) and maximum post-HSCT (2473 ng/mL versus 1591 ng/mL; P < .001) median ferritin levels were statistically higher in the patients with malignancies. Radiologic assessment of IOL confirmed a more severe degree in patients with malignant disorders compared to those with benign disorders (median T2*-MRI, 4.20 msec [interquartile range (IQR), 3.0 to 6.40 msec] versus 7.40 msec [IQR, 4.90 to 11.00 msec]; P = .008). T2* levels were associated with the number of transfusions performed (P = .0006), with a steeper drop in T2* values for the first 20 transfusions and a milder slope for subsequent transfusions. T2* and ferritin values showed a statistically significant negative exponential relationship (P < .0001), although a ferritin level ≥1000 ng/mL showed poor specificity (48%) and low positive predictive value (53%) for discriminating moderate-to-severe IOL from absent-mild IOL as assessed by T2*-MRI, but with high sensitivity (92%) and negative predictive value (91%). In a multivariable model, >20 transfusions (odds ratio [OR], 4.07; 95% confidence interval [CI], 1.61 to 10.68; P = .003) and higher pre-HSCT ferritin level (P < .001) were associated with the risk of developing moderate-to-severe IOL. Use of a sibling donor (OR, .29; 95% CI, .10 to .77; P = .015) and a nonmalignancy (OR, .27; 95% CI, .08 to .82; P = .026) were protective factors. Phlebotomy (66%), low-dose oral chelators (9%), or a combined approach (25%) were started at a median of 12 months after HSCT in 78% of the patients with IOL. Six percent of the patients treated exclusively with phlebotomy (median, 14, significantly higher in patients >40 kg) discontinued phlebotomy owing to poor venous access, lack of compliance, or hypotension, whereas 39% of patients treated with chelators developed mild renal or hepatic side effects that resolved after tapering or discontinuation. Patients with malignancies showed statistically higher pre-HSCT and post-HSCT ferritin levels and lower T2* values. High ferritin level recorded on T2*-MRI showed unsatisfactory diagnostic accuracy in predicting IOL; thus, T2*-MRI should be considered a key tool for confirming IOL after HSCT in patients with an elevated serum ferritin level. IOL treatment is feasible after HSCT.

Does ferritin level affect the outcomes of autologous stem cell transplantation equally in all diseases? Transfus Apher Sci 2023:103655. [PMID: 36805278 DOI: 10.1016/j.transci.2023.103655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2022] [Revised: 02/03/2023] [Accepted: 02/09/2023] [Indexed: 02/18/2023]
Abstract
BACKGROUND In this retrospective study, we evaluated the effect of ferritin levels on the outcomes of autologous stem cell transplantation in patients with MM or lymphoma. METHODS In this study, 170 patients with measured ferritin levels within one month before transplantation who underwent ASCT with the diagnosis of MM or lymphoma were evaluated. The cut-off value of ferritin was determined as 500 ng/mL to evaluate the transplant outcomes in both groups. The hematological recovery status/duration, febrile neutropenia rate, hospitalization time, transplant-related mortality (TRM) in the first 100 days, and OS were evaluated according to the ferritin level RESULTS: Of all patients, 105 (61,8%) were diagnosed with MM and 65 (38.2%) with lymphoma. Ferritin levels had no statistically significant effect on the engraftment status/times, the febrile neutropenia rates, and hospitalization times of both lymphoma and myeloma patients (p > .05). Ferritin level was not significantly associated with TRM in MM (p = .224). However, in lymphoma, ferritin level was significantly associated with TRM (33.3% for ferritin level ≥500 ng/L vs. 5.3% for ferritin level ng/mL, p = .005). There was no statistically significant correlation between ferritin value and OS in MM group [ferritin level ≥ 500 ng/L: 39.9 months (95% CI: 33.7-46.1) and ferritin level 500 ng/mL: 39.4 months (95% CI: 36.5-42.2), p = .446]. Ferritin level was significantly associated with OS in patients with lymphoma [ferritin level ≥ 500 ng/L: 22.1 months 95% CI: 14.7-29.5), ferritin level 500 ng/mL: 27.3 months (95% CI: 22.4-32.2), p = .038] CONCLUSION: High ferritin level is important prognostic factor on survival after ASCT in patients with lymphoma.

Efficacy and Safety of Iron Chelation Therapy After Allogeneic Hematopoietic Stem Cell Transplantation in Pediatric Thalassemia Patients: A Retrospective Observational Study. J Pediatr Hematol Oncol 2022; 44:e26-e34. [PMID: 34986131 DOI: 10.1097/mph.0000000000002328] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/18/2020] [Accepted: 07/02/2021] [Indexed: 01/22/2023]
Abstract
BACKGROUND Studies on the increased body iron load in patients with thalassemia major have thoroughly demonstrated the problems caused by iron overload. In patients who undergo hematopoietic stem cell transplantation (HSCT) as curative therapy, iron overload continues long after transplantation. There are few pediatric studies on chelation therapy in the posttransplant period. In this study, we present the outcomes of our patients who received posttransplant oral chelation therapy. PATIENTS AND METHODS This retrospective observational study evaluated the outcomes of pediatric patients with thalassemia major who used oral chelation therapy after allogeneic HSCT at the Akdeniz University Pediatric Bone Marrow Unit between January 2008 and October 2019. RESULTS Deferasirox therapy was initiated in 58 pediatric patients who underwent HSCT for thalassemia. Pretreatment mean serum ferritin was 2166±1038 ng/mL. Treatment was initiated at a mean of 12±6.7 months after transplantation and continued for a mean of 15.7±11.5 months. At treatment discontinuation, the mean serum ferritin was 693±405 ng/mL and the mean reduction was -1472.75±1121.09 ng/mL (P<0.001 vs. posttreatment). Serum ferritin was below 500 ng/mL in 52% of the patients at treatment discontinuation. Manageable side effects such as nausea, vomiting, liver enzyme elevation, and proteinuria were observed in 17% of the patients, while one patient developed ototoxicity. CONCLUSIONS Deferasirox therapy effectively reduces iron overload in the posttransplant period. Studies evaluating the effects of early treatment on the graft may help to establish guidelines for posttransplant chelation therapy. Clear guidelines are needed regarding when to initiate and discontinue treatment.

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.

Abstract
Iron overload (IO) is common in hematologic malignancies and hemoglobinopathies, largely due to red cell transfusion burden. End-organ damage from IO occurs via reactive oxygen species-mediated pathways. The impact of pretransplant IO on hematopoietic cell transplant (HCT) morbidity and mortality remains contentious; studies have shown mixed results, possibly due to variability in study population and design, as well as markers of IO. Ferritin has served as a traditional circulating marker of total body IO, but liver iron content by MRI appears to be a better marker of end-organ involvement. Novel surrogate markers including hepcidin, marrow Prussian blue staining, and labile plasma iron levels may prove to be more specific for HCT complications. Posttransplant phlebotomy, chelation, or both in combination remains the mainstays of treatment, though may ultimately be supplanted by pretransplant or peri-transplant use of bone marrow maturation agents or targeted chelation at time of highest IO risk. This review discusses the pathophysiology of IO in hematologic disease, the evidence supporting and refuting its negative impact on HCT outcomes, as well as current and future therapies.

Abstract
Haematopoietic stem cell transplant (HSCT) can be a curative treatment for children and adolescents with very-high-risk acute lymphoblastic leukaemia (ALL). Improvements in supportive care and transplant techniques have led to increasing numbers of long-term survivors worldwide. However, conditioning regimens as well as transplant-related complications are associated with severe sequelae, impacting patients' quality of life. It is widely recognised that paediatric HSCT survivors must have timely access to life-long care and surveillance in order to prevent, ameliorate and manage all possible adverse late effects of HSCT. This is fundamentally important because it can both prevent ill health and optimise the quality and experience of survival following HSCT. Furthermore, it reduces the impact of preventable chronic illness on already under-resourced health services. In addition to late effects, survivors of paediatric ALL also have to deal with unique challenges associated with transition to adult services. In this review, we: (1) provide an overview of the potential late effects following HSCT for ALL in childhood and adolescence; (2) focus on the unique challenges of transition from paediatric care to adult services; and (3) provide a framework for long-term surveillance and medical care for survivors of paediatric ALL who have undergone HSCT.

Abstract
OBJECTIVES Myelodysplastic syndrome (MDS) is a highly mortal disease in which anemia is unresponsive to treatment. In this study, the effect of basal ferritin values on prognosis and survival was investigated in MDS patients without history of transfusion. METHODS Data were retrospectively analyzed for 62 MDS cases. The cases were divided into two groups according to ferritin values. RESULTS The mean survival time was 61.1±4.8 months. During the follow-up period, 34 (54.8%) patients deceased. Median ferritin level was 358ng/mL. The serum ferritin (SF) level associated with mortality was determined as 400ng/mL (ROC area for SF was 0.731 with a cutoff value of 400; sensitivity and specificity were 70.7% and 68.2%, respectively) (P=0.002). There were 29 (46.8%) patients with serum ferritin levels of ≥400ng/mL. Patients with serum ferritin levels≥400ng/mL had low survival rates. Ferritin≥400ng/mL was associated with six times increased mortality (P=0.001). CONCLUSION Although the acceptable ferritin level at the start of chelation therapy is 1000ng/mL, the fact that 400ng/mL value is associated with survival in our study suggests that it may be useful to start chelation therapy in the early period. Further case studies on the subject are required.

Abstract
This article discusses the complications of hematopoietic stem cell transplantion (HSCT) that affect infections in HSCT recipients, with analogies to patients with hematologic malignancies. Mucositis, with mucosal barrier disruption, is common and increases the risk of gram-positive and anaerobic bacterial, and fungal infections, and can evolve to typhlitis. Engraftment syndrome; graft-versus-host disease, hepatic sinusoidal obstruction syndrome; and posterior reversible encephalopathy syndrome can affect the infectious potential either directly from organ dysfunction or indirectly from specific treatment. Pulmonary infections can predispose to life threatening complications including diffuse alveolar hemorrhage, idiopathic pulmonary syndrome, bronchiolitis obliterans syndrome, and bronchiolitis obliterans with organizing pneumonia.

Abstract
BACKGROUND The role of serum ferritin (SF) as a prognostic factor has been analyzed in patients with myelodysplastic syndromes (MDS) who have undergone hematopoietic stem cell transplantation (HSCT), but the prognostic role of elevated SF levels is still controversial in lower risk MDS patients. Therefore, we performed a meta-analysis of all available published literature to evaluate whether elevated SF levels are associated with a worse overall survival (OS) among patients with low risk MDS. MATERIAL AND METHODS A systematic bibliographic search of relevant studies was undertaken in accordance with guidelines for meta-analysis of observational studies in epidemiology. Electronic databases were searched through July 2016 for studies examining the level of SF as a prognostic factor in the adults affected by MDS. RESULTS Six articles were included in the meta-analysis. A significant association between OS and SF was achieved for the threshold of SF≥1000 ng/mL, when the only study that used SF cut-off ≥2000 ng/mL was not included in the meta-analysis (RR = 1.33; 95% CI = 1.06-1.67). The estimated risk was 2.58 (95% CI = 1.41-4.74) when a SF cut-off≥500 ng/mL was considered. CONCLUSIONS Our findings underlined a worse survival in patients with MDS who had higher SF levels. The association was stronger and achieved statistical significance after stratification of analyses in which we excluded cut-offs of SF level considered as outliers. These results suggest that negative impact on OS already exist at SF level ≥500 ng/mL. Prospective studies, are needed to better understand this relationship and, above all, to clarify whether earlier iron chelation therapy could improve patients' OS.

Iron is an essential element for key cellular metabolic processes. However, transfusional iron overload (IOL) may result in significant cellular toxicity. IOL occurs in transfusion dependent hematologic malignancies (HM), may lead to pathological clinical outcomes, and IOL reduction may improve outcomes. In hematopoietic stem cell transplantation (SCT) for HM, IOL may have clinical importance; endpoints examined regarding an impact of IOL and IOL reduction include transplant-related mortality, organ function, infection, relapse risk, and survival. Here we review the clinical consequences of IOL and effects of IOL reduction before, during and following SCT for HM. IOL pathophysiology is discussed as well as available tests for IOL quantification including transfusion history, serum ferritin level, transferrin saturation, hepcidin, labile plasma iron and other parameters of iron-catalyzed oxygen free radicals, and organ IOL by imaging. Data-based recommendations for IOL measurement, monitoring and reduction before, during and following SCT for HM are made.

Abstract
Iron overload is an adverse prognostic factor for patients undergoing hematopoietic stem cell transplantation (HSCT). In the HSCT setting, pretransplant and early posttransplant ferritin and transferrin saturation were found to be highly elevated due to high transfusion requirements. In addition to that, post-HSCT iron overload was shown to be related to infections, hepatic sinusoidal obstruction syndrome, mucositis, liver dysfunction, and acute graft-versus-host disease. Hyperferritinemia causes decreased survival rates in both pre- and posttransplant settings. Serum ferritin levels, magnetic resonance imaging, and liver biopsy are diagnostic tools for iron overload. Organ dysfunction due to iron overload may cause high mortality rates and therefore sufficient iron chelation therapy is recommended in this setting. In this review the management of iron overload in adult HSCT is discussed.

Abstract
BACKGROUND Iron overload is one of the most significant problems as a leading cause of death in patients with leukemia and those who underwent allogeneic hematopoietic stem cell transplantation (alloHSCT). METHODS In the current study, we retrospectively evaluated the bone marrow iron scores (BMIS) in patients who underwent alloHSCT (n = 125). The first available bone marrow biopsy specimens prior to the alloHSCT procedure or date of hospitalization (control group) were assessed in a blinded fashion using a standardized scoring system. RESULTS A total of 125 patients were enrolled in the study. Seventy-six (60.8%) of the patients were male, and 49 (39.2%) were female. The median level of pre-transplant serum ferritin was 1023.00 ng/mL (range, 393.80-1627.50 ng/mL). The majority of the patients were diagnosed with acute leukemia (83; 66.4%) and lymphomas (20; 16.0%). The median time for neutrophil engraftment was 14.00 days (range, 13.00-16.00 days) and 11.00 days (range, 10.00-14.00 days) for platelet engraftment. The peri-transplant mortality was similar to international mortality rates (3; 2.4%). The overall survival and disease-free survival were strongly correlated with the degree of BMIS, and both were significantly poorer in patients with high bone marrow iron content (P < .001 and P = .012, respectively). CONCLUSION The validation of BMIS for risk stratification in patients who undergo alloHSCT may predict posttransplant outcomes.

Abstract
Serum ferritin reflects body iron stores, but this correlation is dissociated in inflammation. Ferritin has been shown to be prognostically relevant in breast cancer and in patients with hematologic malignancies undergoing autologous or allogeneic stem cell transplantation. In the present study, we evaluated the prognostic relevance of pretransplant ferritin levels in 137 patients with myeloma (median age: 56 years) subjected to autologous stem cell transplantation in our institution between 1994 and 2010. After completion of induction therapy, a minority of patients had increased β₂-microglobulin (β2M) (> 3.5 mg/L: 30.6%) or low albumin (≤ 3.5 g/dL: 6.8%). Median overall survival from transplantation was 83.9 months. Pretransplant ferritin level was an independent prognostic marker in multivariate analyses (including age and ferritin levels albumin) for progression-free and overall survival and retained prognostic significance in a stepwise backward regression. Iron-independent effects of ferritin in myeloma should be prospectively investigated in preclinical and clinical studies.

Abstract
BACKGROUND Elevated levels of serum ferritin have been documented to be an adverse prognostic factor in patients with hematologic malignancies undergoing hematopoietic stem cell transplantation. The purpose of this study was to estimate the correlation between elevated levels of serum ferritin and survival outcomes in patients with non-Hodgkin lymphoma (NHL). PATIENTS AND METHODS A total of 267 patients who were newly diagnosed with NHL and who received chemotherapy between September 1999 and April 2012 were retrospectively analyzed. RESULTS In multivariate analysis, other chemotherapy regimens excluding CHOP-like chemotherapy regimens (cyclophosphamide, adriamycin, vincristine, prednisolone) and RCHOP (rituximab plus CHOP), a high level of β2-microglobulin, a high-intermediate/high risk according to the international prognostic index (IPI), and elevated levels of serum ferritin were all significant independent prognostic factors for 5-year progression-free survival rates. RCHOP and other chemotherapy regimens, a high level of β2-microglobulin, a high-intermediate/high IPI risk, and high levels of serum ferritin were significant independent prognostic factors for 5-year overall survival rates. CONCLUSION Elevated levels of serum ferritin of 500 ng/mL or more as well as the use of chemotherapy regimens besides CHOP-like or RCHOP, a high-intermediate/high risk IPI, and a high level of beta2-microglobulin in NHL may be an important marker for predicting poor survival outcomes.

Abstract
INTRODUCTION Iron overload (IO) has been shown to be an important cause of mortality and morbidity in patients who underwent allogeneic hematopoietic stem cell transplantation (alloHSCT). This study aimed to evaluate the possible effect of oral iron-chelation treatment (deferasirox) on survival in alloHSCT recipients in the posttransplant period. MATERIALS AND METHODS A total of 80 alloHSCT recipients with IO were analyzed, retrospectively. Pretransplant and posttransplant data were obtained from the patients' files. Patients were divided into two groups. Group 1; patients who did not receive any chelator treatment due to side effects or compliance problems. These patients were treated by phlebotomy. Group 2 consisted of patients who received deferasirox treatment. RESULTS The median treatment duration with deferasirox was 122 days (min-max:91-225). The iron chelating treatment significantly reduced serum ferritin levels administered at a dosage of 20-30 mg/kg/day (p<0.001). The median OS in Group 1 was found 16.0 (min-max:1.0-63.0) months and 25.0 (min-max:3.0-72.0) months in Group 2. In univariate and multivariate analysis, patients in Group 1 showed poorer OS compared to those in Group 2 with an increase in risk of death (HR:3.22, min-max:1.67-6.23, p=0.001 and HR:3.51,, min-max:1.75-6.99, p<0.001; respectively). The median DFS in Group 1 was found 11.0 (min-max:3.0-24.0) months and 22.0 (min-max:8.0-43.0) months in Group 2. The difference was found statistically significant (p=0.023). The other factors that we found significant difference in multivariate analysis between groups were; presence of acute GVHD (patients with aGVHD had increased risk of death compared to patients without aGVHD (HR:2.49, min-max: 1.32-4.69, p=0.005), chronic GVHD (HR:2.57, min-max:1.23-5.41, p=0.013), median interval to tx (HR: 2.23, min-max:1.17-4.26, p=0.015) and HLA match (HR:3.01, min-max:1.35-6.73, p=0.007) CONCLUSION: Oral deferasirox (Exjade) treatment may improve survival in patients with iron overload who underwent alloHSCT.

Abstract
Myelodysplastic syndromes (MDS) are a poorly understood group of disorders caused by one or more genetic aberrations in the bone marrow-derived cell line responsible for hematopoiesis. Recent advances in genetic medicine have offered new insights into the epigenesis as well as the prognosis of MDS, but have not resulted in new or improved curative treatment options. Bone marrow transplantation, introduced before the advent of genetic medicine, is still the only potential cure. Advances in other medical and pharmaceutical areas have broadened the scope of supportive care and disease-modifying therapies, and treating physicians now have a broad range of disease management options depending on a patient's likely prognosis. There is now clear evidence that appropriate supportive care and therapeutic intervention can improve progression-free and overall survival of MDS patients.

Abstract
BACKGROUND Most MM patients develop anemia with progression to symptomatic disease. Usually, this is normocytic/normochromic, with normal or low iron and elevated ferritin levels. Because ferritin levels alone do not correctly reflect iron stores, we performed a comprehensive analysis of iron parameters (iron, ferritin, transferrin, transferrin saturation [TRFS]) to more precisely assess patients' iron metabolism. PATIENTS AND METHODS We analyzed: (1) the frequency of IO vs. ID in 136 consecutive MM patients; (2) the prognostic effect on progression-free (PFS) and overall survival (OS); and (3) specific risk groups according to patients' iron metabolism. RESULTS Most patients had normal iron metabolism or ID: median iron, ferritin, transferrin, and TRFS values were 75 μg/dL, 446 μg/L, 195 mg/dL, and 26%, respectively. Ferritin levels of < 400 μg/L, 400 to 1000 μg/L, and > 1000 μg/L were observed in 46%, 30%, and 24%, and TRFS levels < 20%, 20% to 45%, and > 45% in 32%, 46%, and 22% of patients, respectively. When patients with modified (ID or IO) vs. normal iron metabolism were compared, laboratory parameters (prohormone of brain natriuretic peptide, estimated glomerular filtration rate, c-reactive protein, reflecting cardiac, renal, or infectious impairment), and PFS and OS appeared impaired with modified metabolism, albeit age- and disease-specific differences were insignificant. CONCLUSION Normal iron metabolism and ID is more frequent in MM patients than IO. ID and IO correlate with organ impairment and impaired survival in MM. This knowledge should be incorporated into the design of future studies that will determine the benefit of iron supplementation with ID, and iron chelators with IO in MM.

Abstract
Iron overload (IO), primarily related to multiple red blood cell transfusions, is a relatively common complication in hematopoietic stem cell transplant (HSCT) recipients. Elevated pretransplant ferritin levels have been reported to increase the risk of non-relapse mortality following HSCT and might influence the risk of acute and chronic graft versus host disease. IO has been shown to be an important cause of mortality and morbidity in patients who have undergone alloHSCT (Armand et al., Blood 109:4586-4588, 2007; Kim et al., Acta Haematol 120:182-189, 2008; Kataoka et al., Biol Blood Marrow Transplant 15:195-204, 2009). We know that excessive iron accumulation results in tissue damage and organ failure, mainly as a result of the generation of free radicals that cause oxidative damage and organ dysfunction (e.g., hepatotoxicity, cardiotoxicity, and endocrine dysfunction) (Altes et al., Bone Marrow Transplantation 29: 987-989, 2002; Papanikolaou et al., Toxicol Appl Pharmac 202:199-211, 2005). In the last decade, efforts have been directed toward identifying alternative treatment for IO in alloHSCT recipients to maintain improved transplant outcomes.

Abstract
Context.—Patients who undergo hematopoietic stem cell transplant are at an increased risk of developing iron overload.
Objectives.—To describe the effect of hepatic iron overload on hematopoietic stem cell transplant recipients and to validate the utility of histologic scoring system of iron granules in the liver.
Design.—Records of 154 post allogeneic hematopoietic stem cell transplant patients were reviewed. Forty-nine patients underwent liver biopsy. Histologic hepatic iron overload was defined as a score of 2 or greater (scale, 0–4).
Results.—Twenty-eight of 49 patients (57%) evaluated by liver biopsy had hepatic iron overload; 17 had moderate to severe hepatic iron overload (score, 3 or 4). In multivariate analysis, a significant correlation was discovered between hepatic iron overload and the number of transfusions (P < .001), posttransplant serum ferritin levels (P = .004), lactate dehydrogenase levels (P = .03), and the development of blood stream infections (P = .02). There was no correlation between hepatic iron overload and abnormal liver function test results. While 37 patients (76%) died after receiving a transplant, mortality was not influenced by hepatic iron overload but was significantly higher in older patients, in patients with lower serum albumin levels, higher serum bilirubin levels, and higher clinical grade of acute graft-versus-host disease (P = .04, P = .001, P = <.001, and P = .004, respectively).
Conclusions.—Hepatic iron overload is commonly identified in hematopoietic stem cell transplant patients and can be accurately diagnosed by liver biopsy. In addition, hepatic iron overload has been identified in patients receiving as few as 25 units of packed red blood cells, with elevated posttransplant serum ferritin levels, and with blood stream infections.

Abstract
The myelodysplastic syndromes (MDS) are characterized by cytopenias and risk of progression to acute myeloid leukaemia (AML). Most MDS patients eventually require transfusion of red blood cells for anaemia, placing them at risk of transfusional iron overload. In β-thalassaemia major, transfusional iron overload leads to organ dysfunction and death; however, with iron chelation therapy, organ function is improved, and survival improved to near normal and correlated with the degree of compliance with chelation. In lower-risk MDS, several nonrandomized studies suggest an adverse effect of iron overload on survival and that lowering iron with chelation may minimize this impact. Emerging data indicate that chelation may improve organ function, particularly hepatic function, and a minority of patients may have improvement in cell counts and decreased transfusion requirements. While guidelines for MDS generally recommend chelation in selected lower-risk patients, data from nonrandomized trials suggest iron overload may impact adversely on the outcome of higher-risk MDS and stem cell transplantation (SCT). This effect may be due to increased transplant-related mortality, infection and AML progression, and preliminary data suggest that lowering iron may be beneficial in this patient group. Other areas of active and future investigation include optimizing the monitoring of iron overload using imaging such as T2* MRI and measures of labile iron and oxidative stress; correlating new methods of measuring iron to clinical outcomes; clarifying the contribution of different cellular and extracellular iron pools to iron toxicity; optimizing chelation by using agents that access the appropriate iron pools to minimize the relevant clinical consequences in individual patients; and incorporating measures of quality of life and co-morbidities into clinical trials of chelation in MDS. It should be noted that chelation is costly and potentially toxic, and in MDS should be initiated after weighing potential risks and benefits for each patient until more definitive data are available. In this review, data on the impact of iron overload in MDS and SCT are discussed; for example, several noncontrolled studies show inferior survival in patients with iron overload in these clinical settings, including an increase in transplant-related mortality and infection risk. Possible mechanisms of iron toxicity include oxidative stress, which can damage cellular components, and the documented impact of lowering iron on organ function with measures such as iron chelation therapy includes an improvement in elevated liver transaminases. Lowering iron also appears to improve survival in both lower-risk MDS and SCT in nonrandomized studies. Selected aspects of iron metabolism, transport, storage and distribution that may be amenable to future intervention and improved removal of iron from important cellular sites are discussed, as are attempts to quantify quality of life and the importance of co-morbidities in measures to treat MDS, including chelation therapy.

Abstract
INTRODUCTION Iron overload is an important problem in candidates for and survivors of hematopoietic stem cell transplantation (HSCT), and affects long-term outcome and survival. The objective of the present study was to determine the effect of iron overload on early toxic or infectious complications and survival. PATIENTS AND METHODS We retrospectively reviewed the medical records for 250 adult patients (162 men and 88 women; median [range] age, 34 [16-71] years who underwent HSCT between September 2003 and August 2008. The HSCT grafts were autologous in 102 patients, and allogeneic in 148. RESULTS Follow-up was 315 (1-1809) days. Mean (SD) pre-HSCT serum ferritin concentration was 1402.6 (5016.2) ng/mL in the entire group, 647.6 (1204.3 ng/mL in autologous recipients, and 1410.6 (2410.4) ng/mL in allogeneic recipients. Twenty-eight autologous graft recipients (27.4%) and 102 allogeneic recipients (68.9%) demonstrated serum ferritin concentrations of 500 ng/mL or greater, and were classified as the high-ferritin group. High ferritin concentrations were significantly associated with toxic or infectious complications including mucositis, fungal infections, pneumonia, and sinusoidal obstruction syndrome in the early post-HSCT setting. A significant effect of pre-HSCT ferritin concentration on overall survival and transplant-related mortality was observed. The effect of pre-HSCT ferritin on survival was independent of the comorbidity index at Cox regression analysis. In the entire study population, the probability of survival was significantly lower when ferritin concentration was greater than 500 ng/mL. CONCLUSION Transplant-related mortality has decreased substantially with the development of supportive treatments. Pretransplantation risk assessment and risk-adapted strategies such as decreasing iron overload might further improve transplant-related complications.

Abstract
Recipients of hematopoietic stem cell transplantation (HSCT) frequently have iron overload resulting from chronic transfusion therapy for anemia. In some cases, for example, in patients with myelodysplastic syndromes and thalassemia, this can be further exacerbated by increased absorption of iron from the gut as a result of ineffective erythropoiesis. Accumulating evidence has established the negative impact of elevated pretransplantation serum ferritin, a surrogate marker of iron overload, on overall survival and nonrelapse mortality after HSCT. Complications of HSCT associated with iron overload include increased bacterial and fungal infections as well as sinusoidal obstruction syndrome and possibly other regimen-related toxicities. Based on current evidence, particular attention should be paid to prevention and management of iron overload in allogeneic HSCT candidates, especially in patients with thalassemia and myelodysplastic syndromes. The pathophysiology of iron overload in the HSCT patient and optimum strategies to deal with iron overload during and after HSCT require further study.

Abstract
BACKGROUND Serum ferritin was discovered in the 1930s, and was developed as a clinical test in the 1970s. Many diseases are associated with iron overload or iron deficiency. Serum ferritin is widely used in diagnosing and monitoring these diseases. SCOPE OF REVIEW In this chapter, we discuss the role of serum ferritin in physiological and pathological processes and its use as a clinical tool. MAJOR CONCLUSIONS Although many aspects of the fundamental biology of serum ferritin remain surprisingly unclear, a growing number of roles have been attributed to extracellular ferritin, including newly described roles in iron delivery, angiogenesis, inflammation, immunity, signaling and cancer. GENERAL SIGNIFICANCE Serum ferritin remains a clinically useful tool. Further studies on the biology of this protein may provide new biological insights.

Abstract
The evaluation of patients for hematopoietic stem cell transplantation is a complex process. The decision to recommend transplantation is not simply dependent on patient diagnosis; instead it is a specialized analytic decision process intricately dependent on a number of variables including patient age, performance status, medical comorbidities, family support structure, socioeconomic viability and motivation to participate in self-care, to name a few. The process of pre-transplant patient evaluation has substantial variability across different transplant centers, owing to lack of formal published guidelines. This review summarizes the process of pre-transplant patient evaluation and workup, and aims to describe components of a well-organized and evidenced-based patient selection process for SCT.

Abstract
BACKGROUND/AIMS Serum ferritin is a marker of acute phase reactions and iron storage. In addition, hematologic malignancies are associated with elevated serum ferritin levels. Other studies have suggested that ferritin is a surrogate for advanced disease and has an impact on relapse, because elevated serum ferritin predicts overall survival (OS) and relapse-free survival following autologous stem cell transplantation for lymphomas. METHODS We studied 89 consecutive patients with newly diagnosed multiple myeloma to determine the value of serum ferritin in comparison with known prognostic factors. RESULTS The OS in the elevated serum ferritin group (>or=300 ng/mL) was shorter than that in the normal serum ferritin group (<300 ng/mL, p<0.001) after a median follow-up of 25 months. In univariate analysis, elevated ferritin was correlated with poor survival in the patients (relative risk [RR], 2.588; 95% confidence interval [CI], 1.536 to 4.358; p<0.001). Furthermore, multivariate analysis showed that elevated serum ferritin was an independent predictor of mortality in patients with multiple myeloma (RR, 2.594; 95% CI, 1.403 to 4.797; p=0.002). CONCLUSIONS The serum ferritin can a prognostic parameter of survival as well as disease activity in patients with multiple myeloma.

Abstract
Abstract
Hepatic sinusoidal obstruction syndrome (SOS) is a serious complication in hematopoietic stem cell transplant (HSCT) recipients. To determine the impact of pretransplantation hyperferritinemia on the risk of SOS after HSC transplantation, we retrospectively studied 427 HSCT recipients (179 autologous and 248 allogeneic). Serum ferritin levels were measured before transplantation. Patients with and without a diagnosis of SOS were compared regarding demographics; underlying disease; transplant characteristics; receipt of imatinib, busulfan, total body irradiation, gemtuzumab, vancomycin, acyclovir, or methotrexate; and baseline serum ferritin. Univariate and multivariate (stepwise logistic regression) analyses were performed. SOS was diagnosed in 88 patients (21%) at a median of 10 days (range, 2-29 days) after transplantation. By multivariate analysis, allogeneic HSC transplantation (odds ratio [OR] = 8.25; 95% confidence interval [95% CI], 3.31-20.57), receipt of imatinib (OR = 2.60; 95% CI, 1.16-5.84), receipt of busulfan (OR = 2.18; 95% CI, 1.25-3.80), and ferritin serum level higher than 1000 ng/dL (OR = 1.78; 95% CI, 1.02-3.08) were risk factors for SOS. A ferritin serum level higher than 1000 ng/dL in the pretransplantation period is an independent risk factor for SOS. The results suggest the need for prospective studies addressing the use of iron chelation in the pretransplantation period.
