REVIEW
Theoni Kanellopoulou
Hemolysis after solid organ transplantation can be caused by both immune and non-immune mediated mechanisms and the evaluation must take into account issues distinctive to the post-transplant period. Autoimmune hemolytic anemia usually occurs within the first year and has been attributed to immunosuppressive treatment, infections or underlying post-transplant lymphoproliferative disorder. Review of the literature revealed 59 cases with autoimmune hemolytic anemia mostly in children after liver transplantation...

INTRODUCTION: We present a 51 year old, African American, female who presented with persistent hypoxemia. She had been taking dapsone for many years for prophylaxis against Pneumocystic Jiroveci with no symptoms but eventually developed methemoglobinemia only after a splenectomy. From our literature review there are no documented cases that have demonstrated this relationship between dapsone, splenic function and methemoglobin and we hope to share our perplexing case and shed light on the interaction...

BACKGROUND: Polymorphisms in genes encoding for drug-metabolizing enzymes and drug transporters are among multiple factors that modulate the pharmacokinetic variability of tacrolimus (TAC) and sirolimus (SRL). This study aimed to evaluate the influence of single nucleotide polymorphisms (SNPs) on TAC and SRL dose-adjusted concentrations (C0/D) in stable kidney transplant recipients. METHODS: This is an exploratory and prospective study, which includes 46 stable kidney transplant recipients...

Chronic GvHD (cGvHD) is the leading cause of late non-relapse mortality (NRM) and morbidity after allogeneic hematopoietic stem cell transplant (AHSCT). We analyzed the late effects of a phase II trial testing the efficacy of intermediate dose rabbit anti-thymocyte globulin (Thymoglobulin Thymo) in combination with tacrolimus and sirolimus (TTS) in 47 patients (pts) for the prevention of acute and chronic GvHD after unrelated AHSCT. The median follow-up was 45.2 months. The cumulative incidence of NIH severe cGvHD at 48 months was 6...

Follicular regulatory T (Tfr) cell can effectively regulate humoral immunity, but its function and mechanism in antibody-mediated rejection (AMR) after organ transplantation remains unclear. Here we detected follicular helper T (Tfh) cell subsets in 88 renal transplant patients with chronic renal allograft dysfunction (40 with AMR and 48 without AMR). The ratio of Tfr cells in renal graft tissues and peripheral blood of AMR patients significantly decreased, while the ratio of IL-21-producing Tfh cells (Tfh2 and Tfh17) significantly increased, compared to non-AMR patients...

Despite the abundance of information on cutaneous malignancies associated with solid organ transplantation in the transplant literature, there is limited information regarding non-malignant skin changes after transplantation. There are numerous skin toxicities secondary to immunosuppressive and other transplant-related medications that can vary in presentation, severity, and prognosis. In order to limit associated morbidity and mortality, SOTR care providers should effectively identify and manage cutaneous manifestations secondary to drug toxicity...

RATIONALE: In the determination of immunosuppressive drugs cyclosporine A (CSA), tacrolimus (TARO), sirolimus (SIRO), and everolimus (EVE) in whole blood there is an open debate about which is the best assay between immunochemistry and liquid chromatography/tandem mass spectrometry (LC/MS/MS). This work is aimed to explore this topic, focusing on the use of updated assays and the analysis of a large number of samples. METHODS: A certified in vitro diagnostic kit coupled with a medical device LC/MS/MS was validated and applied to the analysis of 1192 blood samples of patients treated with immunosuppressive drugs...

Mycophenolic acid (MPA), the active compound of mycophenolate mofetil (MMF), is widely used as an antirejection drug after renal transplantation. There is growing evidence supporting the notion that there is substantial variability in the intra- and interpatient exposure to MPA. Drug interactions involving MPA with tacrolimus, steroids, and sirolimus have been understudied. The objective of this study was to determine the relationship between MPA, steroids, tacrolimus, and sirolimus. MPA trough concentrations from 37 pediatric renal transplant recipients (mean age 7...

Posttransplant diabetes mellitus (PTDM) is one of the major metabolic complications after transplantation of solid organs including the kidney. This type of diabetes mellitus affects allograft survival, cardiovascular complications and overall patient survival. The modifiable risk factors that contribute to PTDM include obesity, some viral infections (eg, hepatitis C virus, cytomegalovirus) and especially immunosuppressive drugs including corticosteroids, tacrolimus, cyclosporine and sirolimus. Currently, predisposing genetic factors have been considered important in PTDM development...

There is a paucity of data evaluating acute kidney injury (AKI) incidence and its relationship with the tacrolimus-sirolimus (Tac-Sir) concentrations in the setting of reduced-intensity conditioning (RIC) after allogeneic stem cell transplantation (allo-HSCT). This multicenter retrospective study evaluated risk factors of AKI defined by 2 classification systems, Kidney Disease Improving Global Outcome (KDIGO) score and "Grade 0-3 staging," in 186 consecutive RIC allo-HSCT recipients with Tac-Sir as graft-versus-host disease prophylaxis...

Sirolimus (SIR)/tacrolimus (TAC) is an alternative to methotrexate (MTX)/TAC. However, rational selection among these GvHD prophylaxis approaches to optimize survival of individual patients is not possible based on current evidence. We compared SIR/TAC (n=293) to MTX/TAC (n=414). The primary objective was to identify unique predictors of overall survival (OS). Secondary objective was to compare acute and chronic GvHD, relapse, non-relapse mortality, thrombotic microangiopathy (TMA), hepatic veno-occlusive disease (VOD/SOS), and acute kidney injury...

BACKGROUND: As part of liver transplantation, immunosuppression (suppressing the host immunity) is given to prevent graft rejections resulting from the immune response of the body against transplanted organ or tissues from a different person whose tissue antigens are not compatible with those of the recipient. The optimal maintenance immunosuppressive regimen after liver transplantation remains uncertain. OBJECTIVES: To assess the comparative benefits and harms of different maintenance immunosuppressive regimens in adults undergoing liver transplantation through a network meta-analysis and to generate rankings of the different immunosuppressive regimens according to their safety and efficacy...

OBJECTIVES: De novo donor-specific antibody formation posttransplant is associated with decreased graft survival. It is not known whether mammalian target of rapamycin inhibitors may be advantageous or detrimental compared with mycophenolate in the prevention of de novo donor-specific antibody formation. MATERIALS AND METHODS: We compared 66 kidney and kidney-pancreas transplant recipients who received tacrolimus, mammalian target of rapamycin inhibitor, and prednisone (group 1; 36 of whom received everolimus and 30 of whom received sirolimus) versus 132 patients who received tacrolimus, mycophenolate, and prednisone (group 2) matched for age, sex, race, and type/timing of transplant from 2007 to 2012...

AIM: Hematocrit (Ht) effects remain a challenge in dried blood spot (DBS) sampling. The aim was to develop an immunosuppressant DBS assay on two LC-MS/MS systems covering a clinically relevant Ht range without Ht correction. RESULTS: The method was partially validated for tacrolimus, sirolimus, everolimus, cyclosporin A and fully validated for mycophenolic acid on an Agilent and Thermo LC-MS/MS system. Bias caused by Ht effects were within 15% for all immunosuppressants between Ht levels of 0...

Kaposi᾽s sarcoma (KS) can develop in 0.06% to 4.1% of kidney transplant recipients. Here we describe a case of 50-year-old man who developed KS a few months after kidney transplantation. After transplantation, he had delayed graft function and was managed by anti-thymocyte globulin (ATG) for five days. At the discharge, his immunosuppressive therapy was prednisolone 20 mg/day, tTacrolimus (Pprograf®) 4 mg/day, and mycophenolate mofetil (MMF) 2 gr/day, while he also took Vvalcyte and diltiazem. Once diagnosed with KS, the Prograf® (tacrolimus)  was replaced by prednisolone (5 mg/day) and sirolimus (2 mg/day)...

BACKGROUND: Non-human primates (NHPs) are often used as recipients in preclinical transplantation research that in most cases involves administration of various drugs including immunosuppressants. Long-term oral drug administration, particularly tacrolimus, is challenging in the transplant recipient NHPs. Oral drug administration method using the mixture of drug and fruit juice has been used in NHPs, but this is not always effective in all monkeys. To those monkeys who are poorly compliant, oral drug administration in restraint or administration using gastrostomy tube should be necessary...

Hypertriglyceridemia and hyperlipidemia are the most remarkable metabolic complications seen with long-term sirolimus therapy. We report the case of a 36-year-old woman status post bilateral lung transplantation on a maintenance immunosuppression regimen of sirolimus, tacrolimus, and prednisone who presented with status migrainosus, chest pain, abdominal discomfort, and triglyceride levels greater than 4425 mg/dL. In previously reported cases of severe hypertriglyceridemia that developed on maintenance sirolimus therapy, plasmapheresis has been utilized as an early strategy to rapidly lower triglycerides in order to minimize the risk of acute complications such as pancreatitis, but our case was managed medically without plasmapheresis...

BACKGROUND: The risks for transplant outcomes associated with baseline viral serostatus in kidney transplant recipients (KTR) on sirolimus have not been widely studied. METHODS: We performed a cohort-study of 61 590 adult KTR in 2000 to 2013. We used Cox regression models to determine the adjusted hazard ratio (aHR) of patient death, death-censored graft loss and posttransplant malignancy associated with the baseline serostatus (+ or -: hepatitis B core [HBc], hepatitis C virus [HCV], Epstein-Barr virus [EBV], or cytomegalovirus [CMV]) in KTR on sirolimus (SRL) + mycophenolate (MPA) or SRL + tacrolimus (Tac), relative to the control-regimen: Tac + MPA...
