Ergisi M, Ooi B, Salim O, Papalois V. Post-transplant lymphoproliferative disorders following kidney transplantation: A literature review with updates on risk factors, prognostic indices, screening strategies, treatment and analysis of donor type. Transplant Rev (Orlando) 2024; 38:100837. [PMID: 38430887 DOI: 10.1016/j.trre.2024.100837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2023] [Revised: 01/31/2024] [Accepted: 02/19/2024] [Indexed: 03/05/2024]
Abstract
Post-transplant lymphoproliferative disorders (PTLD) is a devastating complication of kidney transplantation with an insidious presentation and potential to disseminate aggressively. This review delineates the risk factors, prognostic indexes, screening, current management algorithm and promising treatment strategies for PTLD. Kidneys from both extended criteria donors (ECD) and living donors (LD) are being increasingly used to expand the donor pool. This review also delineates whether PTLD outcomes vary based on these donor sources. While Epstein-Barr virus (EBV) is a well-known risk factor for PTLD development, the use of T-cell depleting induction agents has been increasingly implicated in aggressive, monomorphic forms of PTLD. Research regarding maintenance therapy is sparse. The international prognostic index seems to be the most validate prognostic tool. Screening for PTLD is controversial, as annual PET-CT is most sensitive but costly, while targeted monitoring of EBV-seronegative patients was more economically feasible, is recommended by the American Society of Transplantation, but is limited to a subset of the population. Other screening strategies such as using Immunoglobulin/T-cell receptor require further validation. A risk-stratified approach is taken in the treatment of PTLD. The first step is the reduction of immunosuppressants, after which rituximab and chemotherapy may be introduced if unsuccessful. Some novel treatments have also shown potential benefit in studies: brentuximab vedotin, chimeric antigen receptor T-cell therapy and EBV-specific cytotoxic T lymphocytes. Analysis of LD v DD recipients show no significant difference in incidence and mortality of PTLD but did reveal a shortened time to development of PTLD from transplant. Analysis of SCD vs ECD recipients show a higher incidence of PTLD in the ECD group, which might be attributed to longer time on dialysis for these patients, age, and the pro-inflammatory nature of these organs. However, incidence of PTLD overall is still extremely low. Efforts should be focused on optimising recipients instead. Minimising the use of T-cell depleting therapy while encouraging research on the effect of new immunosuppressants on PTLD, screening for EBV status are essential, while enabling shared decision-making during counselling when choosing kidney donor types and individualised risk tailoring are strongly advocated.

Abstract
Background Post-transplant lymphoproliferative disorder (PTLD) is a rare complication following solid organ transplantation and allogeneic hematopoietic stem cell transplantation (Allo-HSCT), which gives rise to high mortality rates. Material/Methods This was a single-center retrospective analysis based on 27 patients who were diagnosed with PTLD following Allo-HSCT between January 1, 2007 and June 2018 at the Chinese PLA General Hospital. The purpose of this analysis was to investigate responses and prognostic factors of rituximab-based treatment. Results Twenty-seven patients were treated with rituximab. Among them, 20 of 27 patients (74.07%) had a complete response, 2 of 27 patients (7.41%) had a partial response, 5 of 27 patients (18.52%) had no response, and 22 of 27 patients (81.48%) cleared Epstein-Barr virus (EBV) copies. There were no obvious side effects. The 1-year overall survival (OS) estimate was 46.8% (95% CI, 23.1–65.5%). Univariate analysis revealed that lower OS was correlated with Eastern Cooperative Oncology Group (ECOG) score standard (3–4), Epstein-Barr virus (EBV) viral load (≥106 copies/mL), bacteria or fungal infection, and EBV reactivation were positive after treatment with 1 or 2 doses of rituximab (P<0.05). Multivariate analysis showed that each of the following were independently associated with lower OS (P<0.05): female, ECOG score standard (3–4), and EBV reactivation were positive after treatment with 1 or 2 doses of rituximab. Conclusions Our results demonstrated that rituximab-based treatment was a safe and effective strategy for patients who were diagnosed with PTLD following Allo-HSCT. The identified prognostic factors may help to detect which PTLD patients are at a higher risk of mortality.

Monomorphic Post-transplant Lymphoproliferative Disorder After Kidney Transplantation and Hematopoietic Stem Cell Transplantation: Clinicopathological Characteristics, Treatments and Prognostic Factors. Indian J Hematol Blood Transfus 2017; 33:492-499. [PMID: 29075059 DOI: 10.1007/s12288-017-0799-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2016] [Accepted: 02/27/2017] [Indexed: 12/21/2022] Open
Abstract
Post-transplant lymphoproliferative disorders (PTLDs) are a heterogeneous group of lymphoid neoplasms associated with immunosuppression following transplantation. Among PTLDs, monomorphic PTLD (m-PTLD) is the largest category; however, its characteristics and survival outcome are not fully understood because of low incidence. This study enrolled 30 adult patients with m-PTLD after kidney-transplantation (KT, n = 17) and hematopoietic stem cell transplantation (HSCT, n = 13) from January 1998 to December 2014. The incidence rates of m-PTLD were 0.74 and 3.63% in the KT and HSCT groups, respectively. M-PTLD patients in the HSCT group were younger and showed earlier onset, with EBV-encoded small RNAs (EBER) more frequently identified. Diffuse large B cell lymphoma (DLBCL) was the main pathological type, and the digestive system was the most extranodal involvement site in m-PTLD after KT and HSCT. Among the 28 patients with DLBCL m-PTLD,the complete remission rate after rituximab treatment was higher than in patients not administered rituximab treatment (P = 0.038). With a median follow-up of 46 months after m-PTLD diagnosis, the estimated 5-year overall survival (OS) was 59.2 ± 9.1% in all patients, and 64.2 ± 11.8 and 52.7 ± 14.1% in the KT and HSCT groups, respectively (P = 0.741). ECOG PS, Ann Arbor stage, and CD68 IHC expression were independent prognostic factors for OS. M-PTLD is a rare but serious complication after transplantation. Ongoing efforts to standardize safe and effective treatment protocols would improve the poor overall survival. The independent prognostic factors contributed to risk-stratified treatment, and might be validated by larger studies.

Abstract
The risk of lymphoma, particularly non-Hodgkin's lymphoma, is an important concern associated with therapy for inflammatory bowel disease (IBD). Lymphoma risks have been described for nearly all immunomodulatory therapies for IBD, and it is therefore important to have discussions with patients before initiating therapy. However, it is also important to put risks into contexts that IBD patients can appropriately appreciate. Relative risks can appear large for these medications, while, by contrast, the absolute risk may be quite low. Additionally, understanding the risks of foregoing immunomodulatory therapy--specifically, continued active disease and/or continued corticosteroid use--can frame an appropriate risk-benefit discussion for both patients and physicians.

Abstract
BACKGROUND AND OBJECTIVES Allograft involvement can occur in some renal transplant recipients who develop post-transplant lymphoproliferative disorders (PTLD). We aimed to find indications and/or contraindications for nephrectomy in renal allograft PTLD based on an outcome analysis of previous reports. DESIGN AND SETTING A comprehensive search of Pubmed and Google scholar was performed to find reports of different treatment strategies addressing PTLD occurring within the allograft after renal transplantation. PATIENTS AND METHODS Patients who underwent nephrectomy due to kidney allograft localization by PTLD were categorized as the case group, and renal recipients with kidney PTLD for whom nonsurgical treatment modalities were used served as controls. RESULTS Survival analysis demonstrated that patients with renal allograft involvement who underwent allograft nephrectomy had a significantly better outcome compared to patients for whom a non-surgical approach was used (P=.03). In patients with disseminated PTLD, nephrectomy was not useful (P>.1). Patients with simultaneous kidney and lung complications by PTLD benefitted from nephrectomy. CONCLUSIONS We found that patients with renal graft complication with disseminated PTLD do not benefit from nephrectomy, which can be considered the only contraindication. However, some particular PTLD co-localizations were not as likely to adversely affect the benefit of nephrectomy in these patients, and these can be considered indications for the procedure. Future multicenter studies are needed to confirm our results.

Abstract
Objective Few cases of graft posttransplant lymphoproliferative disease (PTLD) in pulmonary transplant recipients have been reported. Published data on PTLD are pooled to analyze and compare characteristics, predictors, and prognosis of pulmonary PTLDs arising in lung allograft recipients. Materials and Methods PubMed and Google Scholar were searched for reports of lymphoproliferative disorders occurring within the graft in lung transplant recipients. Data from 23 studies were pooled and analyzed. Results Data from 137 patients (61 graft locations) with PTLD after lung transplantation were analyzed. Lung recipients with pulmonary graft PTLD were significantly more likely to have early-onset PTLD (70% vs 31%, respectively; P< .001). Lung graft PTLD also was associated with having tested negative for infection with Epstein-Barr virus before transplantation ( P = .05). Log-rank test showed significantly higher survival rates for pulmonary transplant recipients with allograft complication than for recipients with PTLD elsewhere ( P = .02). Conclusion Pulmonary transplant recipients who show early symptoms of impaired graft function should be evaluated for a potential lung graft PTLD in addition to being assessed for risk of rejection. Further prospective studies with large populations of patients are needed to confirm these results.

Abstract
BACKGROUND Post-transplant lymphoproliferative disorder (PTLD) is a complication of organ transplantation. The risk of developing PTLD varies depending on a number of factors, including the organ transplanted and the degree of immunosuppression used. METHODS We report a retrospective analysis of 35 patients with PTLD treated at our center after lung transplantation. Of 705 patients who received allografts, 34 (4.8%) developed PTLD. One patient underwent transplantation elsewhere and was treated at our center. RESULTS PTLD involved the allograft in 49% of our patients and the gastrointestinal (GI) tract lumen in 23%. Histologically, 39% of tumors were monomorphic and 48% polymorphic. The time to presentation defined the location and histology of disease. Of 17 patients diagnosed within 11 months of transplantation, PTLD involved the allograft in 12 (71%) and the GI tract in 1 (p = 0.01). This "early" PTLD was 85% polymorphic (p = 0.006). Conversely, of the 18 patients diagnosed more than 11 months after transplant, the lung was involved in 5 (28%) and the GI tract in 7 (39%; p = 0.01). "Late" PTLD was 71% monomorphic (p = 0.006). Median overall survival after diagnosis was 18.57 months. Overall survival did not differ between all lung transplant recipients and those who developed PTLD. CONCLUSIONS PTLD is an uncommon complication after lung transplantation, and its incidence declined remarkably in the era of modern immunosuppression. We report several factors that are important for predisposition toward, progression of, and treatment of PTLD after lung transplantation.

Abstract
Organ transplantation increases risk of non-Hodgkin lymphoma (NHL), but long-term risk and time trends have seldom been evaluated. Immunosuppressive drug load is an important risk determinant, but the details are unclear. We studied NHL risk in a nationwide Swedish cohort of 11 081 graft recipients transplanted 1970-2008. Relative risks (RRs) were estimated within the cohort and versus the general population by age, sex, follow-up time and calendar period. NHL risk was also assessed by cumulative and average doses of immunosuppressive treatments in a nested case-control design throughout 1997 using conditional logistic regression. We observed 153 NHL cases during 97 853 years of follow-up. Compared with the general population, NHL risk was eightfold increased (RR 7.9; 95% confidence interval [CI] 6.6-9.4), and increased risks persisted after ≥15 years of follow-up among kidney (6.1; 95% CI 3.5-10) and nonkidney recipients (44; 14-103). Among nonkidney recipients, NHL risk was lower in the 2000s compared with the 1990s (0.5; 95% CI 0.3-1.0; p = 0.04). A high average dose of antithymocyte immunoglobulin (ATG) conferred an eightfold increased risk of NHL (OR 8.5; 95% CI 1.9-38). To conclude, posttransplant NHL risk decreased during the last decade among nonkidney recipients, possibly because of a more careful use of ATG, the introduction of new drugs, or both.

Abstract
Autoimmune hepatitis (AIH) is an immune-mediated necroinflammatory condition of the liver. Presentation can vary from the asymptomatic individual with abnormal liver function test to fulminant liver failure. The diagnosis is based on the combination of biochemical, autoimmune, and histological parameters, and exclusion of other liver diseases. Standard therapy consists of a combination of corticosteroids and azathioprine, which is efficacious in 80% of patients. Alternative therapies are increasingly being explored in patients who do not respond to the standard treatment and/or have unacceptable adverse effects. This review examines the role of alternative drugs (second-line agents) available for AIH treatment non-responders. These agents include budesonide, mycophenolate mofetil, cyclosporin, tacrolimus, 6-mercaptopurine, 6-thioguanine, rituximab, ursodeoxycholic acid, rapamycin, and methotrexate. In addition, the risk of opportunistic infections and malignancies are discussed. A treatment algorithm is proposed for the management of patients with AIH treatment non-responders.

Abstract
This article describes the cancer risks of commonly used inflammatory bowel disease (IBD) medications, with an emphasis on hematologic malignancy risks. The increasing use of immunosuppressant therapies in the treatment of IBD has raised this question to an even greater importance. Studies evaluating these medications are complicated due to varying disease severity and concomitant use of other immunosuppressant medication. The potential risks of all therapies must be weighed against the benefits these therapies can offer these patients.
