Abstract
Lymphocyte trafficking via chemokine receptors such as C-C chemokine receptor 5 (CCR5) and CXCR3 plays a critical role in the pathogenesis of acute graft-versus-host disease (aGVHD). Our previous studies showed that the addition of CCR5 or CXCR3 antagonists could only slightly alleviate the development of aGVHD. Given the specificity of T lymphocytes bearing CXCR3 and CCR5, we investigated whether combined CCR5 and CXCR3 blockade could further attenuate murine aGVHD. A mouse model of aGVHD was established to assess the efficacy of CCR5 and/or CXCR3 blockade on the development of aGVHD. The distribution of lymphocytes was calculated by quantification of immunostaining cells. The immunomodulatory effect on T cells was assessed by evaluating T-cell proliferation, viability, and differentiation. Using the murine allogeneic hematopoietic stem cell transplantation model, we demonstrated that blockade of both CCR5 and CXCR3 could efficiently alleviate the development of aGVHD. Further investigation on the immune mechanisms for this prophylactic effect showed that more T cells were detained into secondary lymphoid organs (SLOs), which may lead to reduced infiltration of T cells into GVHD target organs. Our study also showed that T cells detained in SLOs dampened the activation, suppressed the polarization toward T helper type 1 (Th1) and T cytotoxic type 1 (Tc1) cells, and induced the production of Treg cells. These data suggest that concurrent blockade of CCR5 and CXCR3 attenuates murine aGVHD through modulating donor-derived T-cell distribution and function, and this might be applicable for aGVHD prophylaxis in clinical settings.

Abstract
BACKGROUND Hematopoietic stem cell transplantation (HSCT) is a common and effective treatment for multiple malignant and non-malignant pediatric conditions. Graft-versus-host disease (GVHD) is a common complication of HSCT that can be prevented with prophylactic use of calcineurin inhibitor (CNI) immunosuppressants. A complication of HSCT and CNI use is pericardial effusion (PEF), which is frequently treated by CNI discontinuation with or without surgical intervention. No studies to date have evaluated the management of PEF without CNI discontinuation as a means of preventing GVHD flares. METHODS In this single-center retrospective study, we reviewed the management of PEF in pediatric patients post-HSCT who received conservative or surgical intervention with or without CNI discontinuation between May 2012 and June 2022. RESULTS Of the patients found to have PEF, all were given tacrolimus for GVHD prophylaxis. Management of PEF included surgical intervention for 83% of patients, and CNI was not discontinued for 83%. None of the patients developed GVHD during the management of PEF. CONCLUSIONS Our results demonstrate that continuation of CNI therapy for GVHD prophylaxis did not negatively impact the disease course of PEF in post-HSCT patients.

Comparison of tacrolimus vs. cyclosporine in pediatric hematopoietic stem cell transplantation for thalassemia. Pediatr Transplant 2024; 28:e14688. [PMID: 38317344 DOI: 10.1111/petr.14688] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 12/13/2023] [Accepted: 12/20/2023] [Indexed: 02/07/2024]
Abstract
OBJECTIVES Graft-versus-host disease (GvHD) is one of the leading causes of morbidity and mortality in patients undergoing allogeneic HSCT, and effective prevention of GvHD is critical for the success of the HSCT procedure. Calcineurin inhibitors (CNI) have been used for decades as the backbone of GvHD prophylaxis. In this study, the efficacy and safety of Cyclosporine A (CsA) and tacrolimus (TCR) were compared in pediatric HSCT for thalassemia. MATERIALS AND METHODS This is a retrospective analysis of 129 pediatric patients who underwent HSCT with the diagnosis of thalassemia at Medicalpark Göztepe and Antalya Hospitals between January 2017 and December 2020. RESULTS Despite the GvHD prophylaxis, grade II-IV acute GvHD developed in 29 patients. Of these patients, 12 had only gut, 10 had only skin, 6 had combined gut and skin, and one had only liver GvHD. Fifteen of these 29 patients were in the CsA group, and 14 of them were in the TCR group. There was no significant difference between the groups in terms of acute GvHD occurrence, GvHD stage, or involvement sites. In terms of CNI-related toxicity, neurotoxicity in 15 (CsA n = 9, TCR n = 6) and nephrotoxicity in 18 (CsA n = 4, TCR n = 14) patients were observed. While there was no difference between the two groups in terms of neurotoxicity, more nephrotoxicity developed in patients using TCR (p = .013). There was no significant difference between the groups in terms of engraftment syndrome, veno-occlusive disease, CMV reactivation, PRES, or graft rejection. CONCLUSION Regarding GvHD, there was no difference in efficacy between TCR and CsA usage. Patients taking TCR experienced noticeably higher nephrotoxicity in terms of adverse effects. This difference should be considered according to the patient's clinical situation while choosing a CNI.

Abstract
Ethiopia is attempting to reduce cancer-related morbidity and mortality through a strategic national cancer control plan but according to Globocan 2020, hematologic malignancies particularly leukemia and non-Hodgkin's lymphoma rank among the top five leading causes of new cancer incidence and cause of death among all age groups in both sexes. Hematopoietic stem-cell transplantation (HSCT) is an advanced treatment modality that makes the only effective treatment for cancer and non-cancer-related hematologic diseases unresponsive to conventional therapy. Patients who need stem cell transplants must travel to abroad countries to get the treatment. Meanwhile, the Ethiopian National Specialty and Subspecialty Roadmap sets the goal of establishing HSCT centers in 2020-2029 GC, yet leaders and planners must start taking steps to put the setup in place. Setting up an HSCT facility is challenging for developing countries due to the high costs, limited infrastructure, and need for intensive medical staff training; however, several nations have been able to start successful stem cell transplant programs. This review summarizes the basic steps and requirements of the program in light of guidelines recommendations and lessons learned from other developing countries. It also highlights possible cost-effective opportunities, bottlenecks, and areas that will require work and investment to make the objective reality in Ethiopia. Provides key information to assist administrators and policymakers to set priorities in planning and making informed decisions to establish and maintain the service.

Influential Factors and Efficacy Analysis of Tacrolimus Concentration After Allogeneic Hematopoietic Stem Cell Transplantation in Children with β-Thalassemia Major. PHARMACOGENOMICS & PERSONALIZED MEDICINE 2021; 14:1221-1237. [PMID: 34594128 PMCID: PMC8478485 DOI: 10.2147/pgpm.s325103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Accepted: 09/15/2021] [Indexed: 11/23/2022]
Abstract
Purpose To analyze factors influencing tacrolimus (TAC) trough concentration (C0) in β-thalassemia major (β-TM) pediatric patients after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and to investigate the effects of genotype polymorphism and drug-drug interactions on TAC trough concentration in children with β-TM. Furthermore, to analyze the correlation between TAC C0 and efficacy and adverse reactions. Patients and Methods Prospectively collection of demographic information and details of combined treatment of patients with β-TM receiving HSCT, and genotypes of CYP3A4, CYP3A5, and ABCB1 (rs1045642, rs1128503, rs2032582) were obtained for each patient. Univariate analysis and multiple linear regression analysis were used to investigate influencing factors on TAC C0. The impact of different genotypes and the co-administration of azole antifungal drugs on β-TM patients receiving TAC were evaluated, together with the correlation between acute graft-versus-host disease (aGVHD), infection, and liver injury of TAC C0. Results A total of 46 patients with 587 concentration data were included. The multiple linear regression results showed that the patient's sex, weight, postoperative time, hemoglobin, platelet count, serum cystatin C, and combined voriconazole were independent influencing factors of the infusion trough concentration/daily dose, C0/Div. Age, body surface area, postoperative time, co-administration of voriconazole, and CYP3A4*18B are independent influencing factors of C0/Dpo. Group comparisons showed that voriconazole can affect TAC C0 administered intravenously (IV) and orally in β-TM pediatric patients, while patient genotype can affect TAC C0 during oral administration. TAC C0 does not correlate with aGVHD or liver injury, but infection may be associated with TAC C0. Conclusion The concentration of TAC should be closely monitored when co-administered with voriconazole. It is worth considering that the influence of genotype on the trough concentration of oral TAC and individualized drug administration warrant investigation. Finally, this study indicated that C0 is not suitable as an indicator of the efficacy of TAC.

Abstract
Cyclosporin a (CsA) was characterized by a narrow therapeutic window and high interindividual pharmacokinetic variability. In this study, we aimed to identify the association of CYP3A4, ABCB1, ABCC2, ABCG2, NFKB1, POR, and PXR polymorphisms with CsA concentrations in patients with allogeneic haematopoietic cell transplantation (allo-HSCT) based on the route of administration.A total of 40 allo-HSCT recipients receiving CsA were genotyped for CYP3A4, ABCB1, ABCC2, ABCG2, NFKB1, POR, and PXR polymorphisms. The correlation between polymorphisms and CsA concentration was analysed.The CsA dose-adjusted trough concentration (Cssmin/D) of oral or intravenous administration was significantly different (p < 0.001). For CsA Cssmin/D of intravenous administration, CYP3A4 rs2246709 (p = 0.015), ABCC2 rs717620 (p = 0.024), ABCG2 rs2231142 (p = 0.042), PXR rs3732359 (p = 0.008), PXR rs3814058 (p = 0.028) and PXR rs6785049 (p < 0.001) had a significant effect on CsA Cssmin/D. For CsA Cssmin/D of oral administration, ABCC2 rs717620 (p = 0.009) and ABCG2 rs2231142 (p = 0.011) had a significant effect on CsA Cssmin/D.These results illustrated that the CYP3A4, ABCC2, ABCG2, and PXR genotypes were closely correlated with CsA Cssmin/D, suggesting these SNPs were suitable for determining the appropriate dose of CsA.

Abstract
Cell-cell contact participates in the process of mesenchymal stromal cell (MSC)-mediated T cell modulation and thus contributes to MSC-based therapies for various inflammatory diseases, especially T cell-mediated diseases. However, the mechanisms underlying the adhesion interactions between MSCs and T cells are still poorly understood. In this study, we explored the interaction between MSCs and T cells and found that activated T cells could rapidly adhere to MSCs, leading to significant reduction of TNF-α and IFN-γ mRNA expression. Furthermore, TCR-proximal signaling in activated T cells was also dramatically suppressed in the MSC co-culture, resulting in weakened Ca2+ signaling. MSCs rapidly suppressed TCR signaling and its downstream signaling in a cell-cell contact-dependent manner, partially through the ICAM-1/CD43 adhesion interaction. Blockade of either ICAM-1 on MSCs or CD43 on T cells significantly reversed this rapid suppression of proinflammatory cytokine expression in T cells. Mechanistically, MSC-derived ICAM-1 likely disrupts CD43-mediated TCR microcluster formation to limit T cell activation. Taken together, our results reveal a fast mechanism of activated T cell inhibition by MSCs, which provides new clues to unravel the MSC-mediated immunoregulatory mechanism for aGVHD and other severe acute T cell-related diseases.

Abstract
Philadelphia chromosome-positive acute myeloid leukemia (Ph+ AML) confers a dismal prognosis when treated with chemotherapy alone. Data on allogeneic hematopoietic cell transplantation (allo-HCT) outcomes are limited. We retrospectively analyzed 4649 AML patients who received allo-HCT and were in complete remission. Outcomes of Ph+ AML (n = 30), intermediate-risk, and poor-risk AML patients were compared. The 3-year overall survival after allo-HCT was similar in intermediate-risk (62.7%; 95% CI: 61.0-64.3%) and Ph+ AML (73.3%; 95% CI: 51.5-86.4%) groups (P = 0.42); however, it differed significantly between the poor-risk (49.7%; 95% CI: 45.9-53.4%) and Ph+ AML (73.3%; 95% CI: 51.5-86.4%) groups (P = 0.049). Disease-free survival in Ph+ AML patients was comparable to that in intermediate-risk patients but better than that in poor-risk patients. Relapse rates were significantly lower in Ph+ AML patients than in other groups. Non-relapse mortality (NRM) rates were similar among groups. Multivariate analysis showed that Ph+ AML was not a significant predictor of poor prognosis in terms of overall survival, disease-free survival, relapse, and NRM. Our data showed better post-transplant outcomes for Ph+ AML patients than for those with poor-risk AML. Hence, allo-HCT could be a feasible treatment option for Ph+ AML patients.
