Beneficial outcomes and epidemiologics of atypical electrophoretic profiles arising after allogeneic hematopoietic stem cell transplantation for myeloid malignancies. Curr Res Transl Med 2021; 70:103322. [PMID: 34801813 DOI: 10.1016/j.retram.2021.103322] [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: 12/14/2020] [Revised: 11/05/2021] [Accepted: 11/09/2021] [Indexed: 11/22/2022]
Abstract
PURPOSE OF THE STUDY Atypical serum protein electrophoresis (SPE) profiles may arise in patients who received allogeneic hematopoietic stem cell transplantation (allo-HSCT), but little is known about their clinical significance. Atypical SPE combine either monoclonal and oligoclonal components, suspected on SPE and confirmed by immunofixation. The aim of the study is to analyze the incidence, the etiology and the clinical significance of atypical SPE profiles in patients who received allo-HSCT. PATIENTS AND METHODS This retrospective study enrolled 117 patients with myeloid malignancies who received an allo-HSCT between 2012 and 2018. We excluded patients with lymphoid malignancies or multiple myeloma, patients presenting atypical electrophoresis prior to transplantation and patients who died within 100 days post-transplant. RESULTS Atypical SPE occurred in 42.7% of patients. The cumulative incidence of atypical profiles was significantly higher in patients with acute Graft Versus Host Disease (GVHD, p = 0.019) and in patients with Cytomegalovirus (CMV) reactivation (p = 0.0017). We observed for the first time that atypical SPE profiles mostly occurred in patients transplanted from a CMV+ donor (p = 0.031). CMV reactivation preceded the occurrence of atypical SPE in the majority of patients. We show that atypical SPE delay the relapse of the underlying malignant disease (486 vs 189 days, p = 0.006), and significantly improve overall survival (OS; 33.1 months vs 28.3 months, p = 0.049). In both univariate and multivariate analyzes, the presence of an atypical SPE is the only factor that significantly improves OS. CONCLUSIONS The occurrence of atypical SPE profiles after allo-HSCT may reflect an adapted post-transplant immune response leading to favourable outcomes.

Transient paraproteinemia after allogeneic hematopoietic stem cell transplantation is an underexplored phenomenon associated with graft versus host disease. Oncotarget 2017; 8:106333-106341. [PMID: 29290952 PMCID: PMC5739737 DOI: 10.18632/oncotarget.22462] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2017] [Accepted: 10/27/2017] [Indexed: 01/12/2023] Open
Abstract
The clinical and biological relevance of a paraprotein that newly arises after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in non-myeloma patients is unknown. In this study, the incidence, the course, and the clinical impact of paraproteins found after allo-HSCT were investigated in a cohort of 383 non-myeloma patients. Paraproteinemia after allo-HSCT was more frequent (52/383 patients, 14%) than the reported incidence of monoclonal gammopathy of unknown significance (MGUS) in age-matched healthy subjects and, in contrast to MGUS, did not correlate with age. In most patients (32/52, 62%), the paraprotein appeared transiently within the first year after allo-HSCT with a median duration of 6.0 months. Post-allo-HSCT paraproteinemia was significantly associated with graft versus host disease (GvHD) and correlated with a survival benefit within the first year, but not after five years following allo-HSCT. Importantly, patients with post-allo-HSCT paraproteinemia did not progress into a plasma cell myeloma as observed for MGUS inferring a distinct pathogenic mechanism. Skewing of lymphocyte subpopulations and alterations in cytokine levels in GvHD may explain the expansion of a specific plasma cell subset in non-myeloma patients undergoing allo-HSCT. Our data suggests that paraproteinemia after allo-HSCT is a reactive phenomenon rather than the consequence of clonal plasma cell transformation.

Abstract
After allogeneic hematopoietic stem cell transplantation (HSCT), recovery of humoral immunity is essential to protect from life-threatening infections. However, monitoring the humoral immune system after transplantation with standard techniques in the clinical routine is imprecise. Here, we performed sequencing of mononuclear bone marrow cells to characterize the VH1-repertoire of switched B cells of healthy volunteers and patients undergoing HSCT. Analysis of healthy bone marrow donors and patients showed virtually no clonally related sequences between individuals. Interestingly, clonally related sequences were present in pre- and post-transplantation bone marrow of patients undergoing HSCT for acute myeloid leukemia treatment. We consistently observed such related B cell clones, irrespective of conditioning regimen, donor source or time post transplantation. In general, repertoire diversity was lower in post-HSCT as compared to pre-HSCT samples. However, post-HSCT repertoires retained highly mutated sequences, despite immunosuppressive therapy and presence of T cell deficiency after HSCT. These observations identify key properties of the recovering B cell compartment and provide a conceptual framework for the surveillance of humoral immunity after allogeneic transplantation.

Mixed T Cell Chimerism After Allogeneic Hematopoietic Stem Cell Transplantation for Severe Aplastic Anemia Using an Alemtuzumab-Containing Regimen Is Shaped by Persistence of Recipient CD8 T Cells. Biol Blood Marrow Transplant 2016; 23:293-299. [PMID: 27816648 PMCID: PMC5270460 DOI: 10.1016/j.bbmt.2016.11.003] [Citation(s) in RCA: 22] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2016] [Accepted: 11/01/2016] [Indexed: 01/08/2023]
Abstract
Clinical outcomes are excellent using an alemtuzumab-containing hematopoietic stem cell transplantation regimen for aplastic anemia. Outcomes are excellent despite prolonged abnormality of the T cell profile. Recipient-derived CD8 T cells shape persistent mixed chimerism.
Prevention of graft-versus-host disease (GVHD) is paramount for allogeneic hematopoietic stem cell transplantation (HSCT) to treat nonmalignant diseases. We previously reported that allogeneic HSCT for severe aplastic anemia (SAA) using the fludarabine, cyclophosphamide, and alemtuzumab (Campath-1H) (FCC) regimen is associated with a very low risk of GVHD and excellent clinical outcomes. We now report a single-center study of 45 patients with longer follow-up and investigation of lymphocyte recovery. Overall survival (OS) was 93%, and event-free survival (EFS) was 90.7%. Acute and chronic GVHD each occurred in 6 patients (13.3%), and only 1 case was severe. Mixed T cell chimerism was frequent and persisted after cessation of immunosuppression. T cells were extensively depleted, representing only 11.3% of lymphocytes at day 30 and rising to 43.8% by 1 year, but still significantly below normal levels (67.2%; P = .018), and deficiency persisted after immunosuppressive therapy (IST) withdrawal. Depletion of CD4 T cells was particularly profound, causing inversion of the normal CD4:CD8 T cell ratio. T cell subset composition was also abnormal, with memory and effector T cells predominating for at least 6 months after FCC HSCT. Analysis of T cell subset chimerism showed that CD4 T cells were predominantly donor-derived at 1 year, whereas recipient-derived CD8 T cells shaped mixed chimerism with a notable contribution of recipient effector CD8 T cells. The prolonged mixed T cell chimerism after IST withdrawal and low incidence of GVHD indicates the establishment of mutual tolerance, but the low incidence of viral disease suggests maintenance of antiviral immunity. Our study shows that despite the abnormal T cell profile after allogeneic HSCT for SAA using the FCC regimen, this regimen is conducive to an excellent clinical outcome.

Abstract
BACKGROUND Transplant recipients are at risk of posttransplant lymphoproliferative disease (PTLD). METHODS Thirty-six pediatric transplant recipients were evaluated (18 hematopoietic stem cell and 18 liver recipients; 12 had PTLD). We studied 207 longitudinal plasma samples from these recipients for three markers of B-cell activation or clonality: immunoglobulin free light chains (FLCs), soluble CD30 (sCD30), and monoclonal immunoglobulins (M-proteins). RESULTS Kappa FLCs, lambda FLCs, and sCD30 were elevated in 20.8%, 28.0%, and 94.2% of plasma specimens, respectively. Free light chain and sCD30 levels increased significantly 1.18 to 1.82 fold per log10 Epstein-Barr virus (EBV) load in peripheral blood. Five PTLD cases manifested elevated FLCs with an abnormal kappa/lambda ratio, suggesting monoclonal FLC production. M-proteins were present in 91% of PTLD cases versus 50% to 67% of other recipients with high or low EBV loads (P=0.13). Concordance of FLCs, M-proteins, and PTLD tumor light chain restriction was imperfect. For example, one PTLD case with an IgG lambda M-protein had a tumor that was kappa restricted, and another case with an M-protein had a T-cell PTLD. In an additional case, an IgM kappa M-protein and excess kappa FLCs were both detected in plasma at PTLD diagnosis; although the tumor was not restricted at diagnosis, kappa restriction was present 5 years later when the PTLD relapsed. CONCLUSIONS Plasma markers of B-cell dysfunction are frequent after transplantation and associated with poor EBV control. These abnormal markers may be produced by oligoclonal B-cell populations or PTLD tumor cells and could potentially help identify recipients at high risk of PTLD.

Abstract
We report the results of a pilot study of a BU-fludarabine-alemtuzumab (BFA)-reduced toxicity conditioning (RTC) followed by allogeneic hematopoietic SCT (AlloHSCT) in 12 children and adolescents (<21 years) with malignant and non-malignant diseases. Stem cell sources were: two unrelated cord blood, one unrelated BM, two related and seven unrelated PBSC. Positive CD34 selection was performed in five unrelated PBSC grafts. RCT was carried out with BFA, and GVHD prophylaxis was FK506 and mycophenolate mofetil. The median time for neutrophil and platelet engraftment was 16 and 31 days, respectively. The P of developing ≥ grade II, ≥ grade III aGVHD and cGVHD was 41.6, 25 and 9%, respectively. Only 1 out of 12 developed ≥ grade III toxicity. There was one primary and no secondary graft failure. Mixed donor chimerism on day 100 and 1 year was median 99 and 96%, respectively; ≥ 90% of recipients achieved ≥ 80% donor chimerism. The 3-year overall survival (OS) in all patients was 91.7 ± 8% (100% for malignant vs. 80% for non-malignant diseases, ns). In all, 11 (91%) patients remain alive at median 2.8 (0.3-6.8) years. RTC followed by AlloHSCT, based on BFA conditioning, is feasible and tolerable in children and adolescents, and results in prompt achievement of durable mixed donor chimerism and excellent OS.

Abstract
Epstein-Barr Virus (EBV) reactivation and EBV-related post-transplant lymphoproliferative disease (PTLD) have emerged as a severe complication after stem cell transplantation (SCT). We prospectively evaluated 104 consecutive patients receiving SCT either autologous or allogeneic. Fifty-two patients (50%) presented EBV DNA-emia and five of them developed PTLD proven or probable. PTLD rate was 9.6% among patients with EBV DNA-emia. One patient developed PTLD without EBV DNA-emia (0.96%). Overall PTLD incidence was 5.7%. No PTLD developed after autologous SCT. EBV DNA-emia was significantly more frequent after allogeneic than autologous SCT (60.7% vs 17.4%, p = 0.0002). At EBV reactivation, serum protein electrophoresis and immunofixation were assessed. Global incidence of γ-peak after allogeneic SCT with EBV reactivation was 65.3% (32/49 patients) and monoclonal gammopathy (MG) was identified in 23/28 evaluable patients (82%). All patients with PTLD developed γ-peak and in five of them MG was identified. MG is consistently associated with EBV DNA-emia and may help identification of progression to PTLD after allogeneic SCT.
