[PMID: 34188518 PMCID: PMC8233479 DOI: 10.2147/pgpm.s295964] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Accepted: 05/20/2021] [Indexed: 12/31/2022]
Abstract
Introduction Mycophenolate mofetil (MMF), a new type of immunosuppressant, has emerged as a frontline agent for treating autoimmune diseases. Mycophenolic acid (MPA) is an active metabolite of MMF. MPA exposure varies greatly among individuals, which may lead to adverse drug reactions such as gastrointestinal side effects, infection, and leukopenia. Genetic factors play an important role in the variation of MPA levels and its side effects. Although many published studies have focused on MMF use in patients after organ transplant, studies that examine the use of MMF in patients with autoimmune diseases are still lacking. Methods This study will not only explore the genetic factors affecting MPA levels and adverse reactions but also investigate the relationships between UGT1A9 −118(dT)9/10, UGT1A9 - 1818T>C, UGT2B7 802C>T, SLCO1B1 521T>C, SLCO1B3 334T>G, IMPDH1 −106G>A and MPA trough concentration (MPA C0), along with adverse reactions among Chinese patients with autoimmune diseases. A total of 120 patients with autoimmune diseases were recruited. The MPA trough concentration was detected using the enzyme multiplied immunoassay technique (EMIT). Genotyping was performed using a real-time polymerase chain reaction (PCR) system and validated allelic discrimination assays. Clinical data were collected for the determination of side effects. Results SLCO1B1 521T>C demonstrated a significant association with MPA C0/d (p=0.003), in which patients with the CC type showed a higher MPA C0/d than patients with the TT type (p=0.001) or the CT type (p=0.000). No significant differences were found in MPA C0/d among the other SNPs. IMPDH1 −106G>A was found to be significantly related to infections (p=0.006). Subgroup analysis revealed that UGT2B7 802C>T was significantly related to Pneumocystis carinii pneumonia infection (p=0.036), while SLCO1B1 521T>C was associated with anemia (p=0.029). Conclusion For Chinese autoimmune disease patients, SLCO1B1 521T>C was correlated with MPA C0/d and anemia. IMPDH1 −106G>A was significantly related to infections. UGT2B7 802C>T was significantly related to Pneumocystis carinii pneumonia infection.

Abstract
ABSTRACT When mycophenolic acid (MPA) was originally marketed for immunosuppressive therapy, fixed doses were recommended by the manufacturer. Awareness of the potential for a more personalized dosing has led to development of methods to estimate MPA area under the curve based on the measurement of drug concentrations in only a few samples. This approach is feasible in the clinical routine and has proven successful in terms of correlation with outcome. However, the search for superior correlates has continued, and numerous studies in search of biomarkers that could better predict the perfect dosage for the individual patient have been published. As it was considered timely for an updated and comprehensive presentation of consensus on the status for personalized treatment with MPA, this report was prepared following an initiative from members of the International Association of Therapeutic Drug Monitoring and Clinical Toxicology (IATDMCT). Topics included are the criteria for analytics, methods to estimate exposure including pharmacometrics, the potential influence of pharmacogenetics, development of biomarkers, and the practical aspects of implementation of target concentration intervention. For selected topics with sufficient evidence, such as the application of limited sampling strategies for MPA area under the curve, graded recommendations on target ranges are presented. To provide a comprehensive review, this report also includes updates on the status of potential biomarkers including those which may be promising but with a low level of evidence. In view of the fact that there are very few new immunosuppressive drugs under development for the transplant field, it is likely that MPA will continue to be prescribed on a large scale in the upcoming years. Discontinuation of therapy due to adverse effects is relatively common, increasing the risk for late rejections, which may contribute to graft loss. Therefore, the continued search for innovative methods to better personalize MPA dosage is warranted.

Effect of inosine monophosphate dehydrogenase-1 gene polymorphisms on mycophenolate mofetil effectiveness in neuromyelitis optica spectrum disorder patients. Mult Scler Relat Disord 2021; 49:102779. [PMID: 33524926 DOI: 10.1016/j.msard.2021.102779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 12/31/2020] [Accepted: 01/16/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND Inosine monophosphate dehydrogenase-1 is the target of mycophenolate mofetil. This research investigated the association between the gene polymorphism of inosine monophosphate dehydrogenase-1 and effectiveness of mycophenolate mofetil therapy in neuromyelitis optica spectrum disorder patients. METHODS Fifty-nine neuromyelitis optica spectrum disorder patients accepted Mycophenolate Mofetil therapy for 1 year at least were divided into two groups: relapsing (n=21) and non-relapsing (n=38). Four single-nucleotide polymorphisms (SNPs: rs2228075, rs2278294, rs2288550, and rs3793165) in the inosine monophosphate dehydrogenase-1 gene were detected. Then we analyzed the allelic frequencies and the genotypes of SNPs in two groups. RESULTS The allelic frequency of rs2278294 distributed differently between the relapse and non-relapsing patients (P=0.03), while no significant difference found in rs2228075, rs2288550 and rs3793165 between two groups. The genotypes C/C, C/T and T/T of rs2278294 (P = 0.031) also distributed differently between the two groups. Logistic regression analysis (adjusted by optic neuritis) showed that compared to the wild genotype C/C, C/T genotype had a 9-fold protection against relapse (OR=0.111 (0.022-0.548)), and T/T genotype had a 6.7-fold protection against relapse (OR=0.149 (0.026-0.854)). CONCLUSION Our study provides preliminary evidence that the genotype of rs2278294 is associated with the response of neuromyelitis optica spectrum disorder patients to mycophenolate mofetil therapy. And compared to wild allelic C, the mutation to T tended to respond better to MMF.

Abstract
Extramedullary relapse (EMR) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) continues to remain a clinical challenge. The data on EMR in acute lymphoblastic leukemia (ALL) are currently limited. Herein, a retrospective analysis of 268 adult ALL patients who underwent allo-HSCT in our center between March 2008 and December 2017 was performed to analyze post-HSCT EMR. Ninety patients (33.58%) experienced relapse; 51(19.03%) experienced bone marrow relapse (BMR), whereas 39 (14.55%) experienced EMR. The 5-year cumulative EMR incidence (CEMRI) revealed that matched sibling donor (MSD)-HSCTs were more likely to develop EMR than unrelated donor (URD)- and haploidentical-related donor (HRD)-HSCTs (CEMRI: 24.02%, 7.69%, and 14.69% for MSD, URD, and HRD, respectively). Notably, MSD-HSCTs (URD vs MSD hazard ratio (HR) = 0.26, p = 0.015; HRD vs MSD HR = 0.46, p = 0.032), history of extramedullary disease (EMD) (HR = 2.45, p = 0.041), and T cell ALL (HR = 2.80, p = 0.012) were independent risk factors for EMR in the multivariate analysis. The median overall survival (OS) for all patients was 15.23 months. However, the OS of EMR patients was significantly longer (19.50 months) than that of BMR patients (12.90 months) (p = 0.003). Multivariate analyses revealed that the leading risk factors for post-relapse deaths were shorter intervals between HSCT and relapse (> 12 months vs ≤ 12 months, HR = 0.30, p < 0.001) and BMR (HR = 0.41, p = 0.002). In conclusion, EMR patients have better survival than BMR patients. ALL patients with allo-HSCT from MSDs, a history of EMD, and the T cell type were significantly associated with EMR.

Disease Progression in Patients with Autosomal Dominant Retinitis Pigmentosa due to a Mutation in Inosine Monophosphate Dehydrogenase 1 (IMPDH1). Transl Vis Sci Technol 2020; 9:14. [PMID: 32821486 PMCID: PMC7401855 DOI: 10.1167/tvst.9.5.14] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2019] [Accepted: 02/10/2020] [Indexed: 02/06/2023] Open
Abstract
Purpose Mutations in the inosine monophosphate dehydrogenase 1 (IMPDH1) gene are a common cause of inherited retinal degeneration (IRD). Due to species- and tissue-dependent expression of IMPDH1, there are no appropriate models of human IMPDH1 disease. Therefore, a limited understanding remains of disease expression and rates of progression for IMPDH1-related IRD. Methods We evaluated semiautomated kinetic and chromatic static perimetry, spectral-domain optical coherence tomography (SD-OCT), and ultra-wide field fundus images with autofluorescence in a cohort of 12 patients (ages 11–58 at first visit). Ten patients had longitudinal data for which rates of progression were estimated. Results Visual acuities were relatively stable over time and the photoreceptors within the central retina remained intact. Perifoveal photoreceptor loss measured over a period of years coincided with visual fields, which were constricted and progressed over time in all patients. Rod sensitivity showed a similar pattern of defect to that of the kinetic perimetry and the autofluorescence ultra-wide field imaging. Full-field electroretinograms were severely reduced and the dark-adapted rod and mixed responses were extinguished at earlier visits than the light-adapted cone responses. Conclusions There was variability in disease severity at the first visit, but results show that the peripheral retina is more susceptible to the deleterious consequences of an IMPDH1 mutation. Given the pattern of degeneration and the alternatively spliced isoforms of IMPDH1, potential interventions may consider targeting the periphery early in disease, modulating transcript expression, and/or preserving central vision at late stages of the disease. Translational Relevance These results inform clinical prognosis and offer evidence strategies toward therapeutic intervention.

Abstract
We evaluated inosine monophosphate dehydrogenase (IMPDH) 1 and IMPDH2 pharmacogenetics in 247 recipient-donor pairs after nonmyeloablative hematopoietic cell transplant (HCT). Patients were conditioned with total body irradiation + fludarabine and received grafts from related or unrelated donors (10% HLA mismatch), with postgraft immunosuppression of mycophenolate mofetil (MMF) with a calcineurin inhibitor. Recipient and donor IMPDH genotypes (rs11706052, rs2278294, rs2278293) were not associated with day 28 T cell chimerism, acute graft-versus-host disease (GVHD), disease relapse, cytomegalovirus reactivation, nonrelapse mortality, or overall survival. Recipient IMPDH1 rs2278293 genotype was associated with a lower incidence of chronic GVHD (hazard ratio, .72; P = .008) in nonmyeloablative HCT recipients. Additional studies are needed to confirm these results with the goal of identifying predictive biomarkers to MMF that lower GVHD.

Abstract
Recent studies have suggested that genomic diversity may play a key role in different clinical outcomes, and the importance of SNPs is becoming increasingly clear. In this article, we summarize the bioactivity of SNPs that may affect the sensitivity to or possibility of drug reactions that occur among the signaling pathways of regularly used immunosuppressants, such as glucocorticoids, azathioprine, tacrolimus, mycophenolate mofetil, cyclophosphamide and methotrexate. The development of bioinformatics, including machine learning models, has enabled prediction of the proper immunosuppressant dosage with minimal adverse drug reactions for patients after organ transplantation or for those with autoimmune diseases. This article provides a theoretical basis for the personalized use of immunosuppressants in the future.

Abstract
Hematopoietic stem cell transplantation is a high-risk procedure that is offered, with curative intent, to patients with malignant and nonmalignant disease. The clinical benefits of personalization of therapy by genotyping have been demonstrated by the reduction in transplant related mortality from donor-recipient HLA matching. However, defining the relationship between genotype and transplant conditioning agents is yet to be translated into clinical practice. A number of the therapeutic agents used in stem cell transplant preparative regimens have pharmacokinetic parameters that predict benefit of incorporating pharmacogenomic data into dosing strategies. Busulfan, cyclophosphamide, thio-TEPA and etoposide have well-described drug metabolism pathways, however candidate gene studies have identified there is a gap in the identification of pharmacogenomic data that can be used to improve transplant outcomes. Incorporating pharmacogenomics into pharmacokinetic modeling may demonstrate the therapeutic benefits of genotyping in transplant preparative regimen agents.

T-cell-replete haploidentical HSCT with low-dose anti-T-lymphocyte globulin compared with matched sibling HSCT and unrelated HSCT. Blood 2014; 124:2735-43. [PMID: 25214441 DOI: 10.1182/blood-2014-04-571570] [Citation(s) in RCA: 143] [Impact Index Per Article: 14.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 12/12/2022] Open
Abstract
We developed an approach of T-cell-replete haploidentical hematopoietic stem cell transplantation (HSCT) with low-dose anti-T-lymphocyte globulin and prospectively compared outcomes of all contemporaneous T-cell-replete HSCT performed at our center using matched sibling donors (MSDs), unrelated donors (URDs), and haploidentical related donors (HRDs). From 2008 to 2013, 90 patients underwent MSD-HSCT, 116 underwent URD-HSCT, and 99 underwent HRD-HSCT. HRDs were associated with higher incidences of grades 2 to 4 (42.4%) and severe acute graft-versus-host disease (17.2%) and nonrelapse mortality (30.5%), compared with MSDs (15.6%, 5.6%, and 4.7%, respectively; P < .05), but were similar to URDs, even fully 10/10 HLA-matched URDs. For high-risk patients, a superior graft-versus-leukemia effect was observed in HRD-HSCT, with 5-year relapse rates of 15.4% in HRD-HSCT, 28.2% in URD-HSCT (P = .07), and 49.9% in MSD-HSCT (P = .002). Furthermore, 5-year disease-free survival rates were not significantly different for patients undergoing transplantation using 3 types of donors, with 63.6%, 58.4%, and 58.3% for MSD, URD, and HRD transplantation, respectively (P = .574). Our data indicate that outcomes after HSCT from suitably matched URDs and HRDs with low-dose anti-T-lymphocyte globulin are similar and that HRD improves outcomes of patients with high-risk leukemia. This trial was registered at www.chictr.org (Chinese Clinical Trial Registry) as #ChiCTR-OCH-12002490.

Role of non-HLA gene polymorphisms in graft-versus-host disease. Int J Hematol 2013; 98:309-18. [PMID: 23949916 DOI: 10.1007/s12185-013-1416-7] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/09/2013] [Revised: 08/05/2013] [Accepted: 08/06/2013] [Indexed: 01/05/2023]
Abstract
A large number of reports have associated various non-HLA gene polymorphisms with the risk and severity of graft-versus-host disease (GVHD). To date, candidate gene studies and genome-wide association studies have been performed to investigate such non-HLA gene polymorphisms in relation to GVHD. Candidate gene studies are hypothesis-driven and cost-effective, whereas genome-wide association studies have the potential to discover new gene polymorphisms, including possible biomarkers and therapeutic targets. Some gene polymorphisms have the potential to affect protein function or gene expression, or to encode minor histocompatibility antigens. Non-HLA genotyping for genes influencing GVHD prior to transplantation should provide useful information that will facilitate choosing the donor, type of graft, conditioning treatment, and GVHD prophylaxis. However, attention should be paid to the need for validation studies and ethical issues.

Lv M, Huang XJ. Allogeneic hematopoietic stem cell transplantation in China: where we are and where to go. J Hematol Oncol 2012; 5:10. [PMID: 22424172 PMCID: PMC3353833 DOI: 10.1186/1756-8722-5-10] [Citation(s) in RCA: 37] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2012] [Accepted: 03/18/2012] [Indexed: 01/29/2023] Open
Abstract
Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is an effective and sometimes the only curative therapy for patients with certain hematological diseases. Allo-HSCT has been practiced in China for approximately 30 years, and great improvements have been made within the past decade, particularly in fields such as the haploidentical HSCT system, strategies to overcome relapse and GVHD, and modified HSCT for elderly patients. This review will describe the current situation and provide a prospective of these unique aspects of Allo-HSCT in China.
