Abstract
Posttransplant lymphoproliferative disorder (PTLD) represents a heterogeneous group of lymphoproliferative diseases occurring in the setting of immunosuppression following hematopoietic stem cells transplant and solid organ transplantation. Despite its overall low incidence, PTLD is a serious complication following transplantation, with a mortality rate as high as 50% in transplant recipients. Therefore, it is important to establish for each transplant recipient a personalized risk evaluation for the development of PTLD based on the determination of Epstein-Barr virus serostatus and viral load following the initiation of immunosuppression. Due to the dynamic progression of PTLD, reflected in the diverse pathological features, different therapeutic approaches have been used to treat this disorder. Moreover, new therapeutic strategies based on the administration of virus-specific cytotoxic T cells have been developed. In this review, we summarize the available data on screening and treatment to suggest a strategy to identify transplant recipients at a higher risk for PTLD development and to review the current therapeutic options for PTLD.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is a leading cause of cancer death in solid organ transplant recipients (SOTRs). Relapsed or refractory (R/R) PTLD portends a high risk of death and effective management is not well established. CD19-targeted CAR-T cell therapy has been utilized, but the risks and benefits are unknown. We report the first case of diffuse large B-cell lymphoma (DLBCL) PTLD treated with lisocabtagene maraleucel and present a systematic literature review of SOTRs with PTLD treated with CD19 CAR-T therapy. Our patient achieved a complete response (CR) with limited toxicity but experienced a CD19+ relapse 8 months after infusion despite CAR-T persistence. Literature review revealed 14 DLBCL and 2 Burkitt lymphoma PTLD cases treated with CD19 CAR-T cells. Kidney (n = 12), liver (n = 2), heart (n = 2), and pancreas after kidney (n = 1) transplant recipients were analyzed. The objective response rate (ORR) was 82.4% (14/17), with 58.5% (10/17) CRs and a 6.5-month median duration of response. Among kidney transplant recipients, the ORR was 91.7% (11/12). Allograft rejection occurred in 23.5% (4/17). No graft failure occurred. Our analysis suggests that CD19 CAR-T therapy offers short-term effectiveness and manageable toxicity in SOTRs with R/R PTLD. Further investigation through larger datasets and prospective study is needed.

Abstract
Post-transplant lymphoproliferative disorder (PTLD) is rare and heterogeneous lymphoid proliferations that occur as a result of immunosuppression following solid organ transplant (SOT) and haematopoietic stem cell transplant (HSCT) with the majority being driven by EBV. Although some histologies are similar to lymphoid neoplasms seen in immunocompetent patients, treatment of PTLD may be different due to difference in pathobiology and higher risk of treatment complications. The most common treatment approach in SOT PTLD after failing immunosuppression reduction (RIS) takes into consideration a risk-stratified sequential algorithm with rituximab +/- chemotherapy based on phase 2 studies. In HSCT PTLD, RIS alone and chemotherapy are usually ineffective making rituximab +/- RIS as the gold standard of frontline treatment. In this review, we give an update on the treatment of PTLD beyond RIS. We highlight the most recent studies that attempted to incorporate more aggressive chemotherapy regimens and novel treatments into the traditional risk-stratified sequential approach. We also discuss the role of EBV-cytotoxic T lymphocytes in treatment of EBV-driven PTLD. Other novel agents with potential role in PTLD will be discussed in addition to the challenges that could arise with chimeric antigen receptor T-cell therapy and immune checkpoint inhibitors in this population.

Abstract
Regulatory T cells (Tregs) play an important role in maintaining immune tolerance and homeostasis by modulating how the immune system is activated. Several studies have documented the critical role of Tregs in suppressing the functions of effector T cells and antigen-presenting cells. Under certain conditions, Tregs can lose their suppressive capability, leading to a compromised immune system. For example, mutations in the Treg transcription factor, Forkhead box P3 (FOXP3), can drive the development of autoimmune diseases in multiple organs within the body. Furthermore, mutations leading to a reduction in the numbers of Tregs or a change in their function facilitate autoimmunity, whereas an overabundance can inhibit anti-tumor and anti-pathogen immunity. This review discusses the characteristics of Tregs and their mechanism of action in select autoimmune skin diseases, transplantation, and skin cancer. We also examine the potential of Tregs-based cellular therapies in autoimmunity.

Post-Transplant Lymphoproliferative Disease (PTLD) after Allogeneic Hematopoietic Stem Cell Transplantation: Biology and Treatment Options. J Clin Med 2022; 11:jcm11247542. [PMID: 36556158 PMCID: PMC9784583 DOI: 10.3390/jcm11247542] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 12/15/2022] [Accepted: 12/16/2022] [Indexed: 12/24/2022] Open
Abstract
Post-transplant lymphoproliferative disease (PTLD) is a serious complication occurring as a consequence of immunosuppression in the setting of allogeneic hematopoietic stem cell transplantation (alloHSCT) or solid organ transplantation (SOT). The majority of PTLD arises from B-cells, and Epstein-Barr virus (EBV) infection is present in 60-80% of the cases, revealing the central role played by the latent infection in the pathogenesis of the disease. Therefore, EBV serological status is considered the most important risk factor associated with PTLDs, together with the depth of T-cell immunosuppression pre- and post-transplant. However, despite the advances in pathogenesis understanding and the introduction of novel treatment options, PTLD arising after alloHSCT remains a particularly challenging disease, and there is a need for consensus on how to treat rituximab-refractory cases. This review aims to explore the pathogenesis, risk factors, and treatment options of PTLD in the alloHSCT setting, finally focusing on adoptive immunotherapy options, namely EBV-specific cytotoxic T-lymphocytes (EBV-CTL) and chimeric antigen receptor T-cells (CAR T).

A Case of Central Nervous System Post-Transplant Lymphoproliferative Disorder Following Haploidentical Stem Cell Transplantation in a Patient With Acute Lymphoblastic Leukemia.

Abstract
We present a differential diagnosis of an intracranial lesion following
haploidentical stem cell transplantation (haplo-SCT) in a female
patient with acute lymphoblastic leukemia (ALL). This patient received
an anti-CD19-chimeric antigen receptor (CAR) T-cell therapy for
refractory B-cell ALL and obtained minimal residual disease
(MRD)-positive (0.03%) complete remission (CR). Then the patient
received a bridging therapy of haplo-SCT. After bridging therapy, the
patient maintained MRD-negative and full donor chimerism in bone
marrow (BM) and was negative for Epstein–Barr virus (EBV)-DNA copy in
peripheral blood. At 91 days after haplo-SCT, the patient presented
with dizziness and fatigue and magnetic resonance imaging (MRI)
demonstrated an intracranial lesion. The diagnosis of isolated
extramedullary relapse (IEMR) was temporarily considered. Then
next-generation sequencing (NGS) identified positive EBV-DNA in the
cerebrospinal fluid, although EBV-DNA in the peripheral blood was
negative. Furthermore, the positive EBV-DNA by NGS and complete donor
chimerism in the brain tissue confirmed the diagnosis of central
nervous system post-transplant lymphoproliferative disorder
(CNS-PTLD). However, the EBV-encoded small RNAs (EBERs) in
situ hybridization was sparsely positive. The patient
was subsequently treated with anti-CD22-CAR T cells in combination
with Zanubrutinib, but the disease progressed quickly and died. Donor
chimerism examination of focal biopsy provides important evidence for
diagnosing PTLD. Furthermore, NGS detection of EBV-DNA in local
lesions is more valuable for diagnosing PTLD than detection of EBV-DNA
in the peripheral blood. Trial registration: The patient was enrolled in a clinical
trial of ChiCTR1800019622 and
ChiCTR1800019298.
