A negative result of therapy based on immunosuppressive drugs is its leading to pathological alterations in the organ, including liver. Use of immunosuppressive medication may also lead to organized and genetically controlled cell death - apoptosis. The aim of this study was to examine histopathological changes in the livers of rats treated with immunosuppressive drugs, and also to determine the effects of different groups of immunosuppressive drugs on apoptosis activity in the hepatocytes of rat livers. The study was conducted on archival material obtained from Department of Nephrology, Transplantology and Internal Medicine of the Independent Public Clinical Hospital No...

Cornerstone immunosuppressive therapy currently relies on immediate-release tacrolimus, a calcineurin inhibitor (CNI) that is potentially nephrotoxic and is more diabetogenic than cyclosporine A. Two new formulations of tacrolimus have been launched: an extended-release formulation (Advagraf®/Astagraf XL®, Astellas company) and a long-lasting formulation (Envarsus®, Veloxis company). Area covered: Herein, we assess the efficacy of an extended-release formulation of tacrolimus (Advagraf®/Astagraf XL®) used in conjunction with or without an induction therapy (i...

Graft survival following pancreas transplant alone (PTA) is inferior to other pancreas transplants. Steroid elimination is appealing, but a two drug maintenance strategy may be inadequate. Additionally, recipients tend to have diabetic nephropathy and do not tolerate nephrotoxic medications. A three-drug maintenance strategy permits immunosuppression through different mechanisms as well as an opportunity to use lower doses of the individual medications. Induction consisted of five doses of rabbit antithymocyte globulin (1 mg/kg/dose)...

BACKGROUND: The most common multiple-organ transplant is the simultaneous pancreas-kidney transplantation (SPK). It is usually offered to patients who have insulin-dependent diabetes mellitus and those with diabetic nephropathy and renal failure that has already been established. In this study we present the results of 15 years of SPK in a transplant hospital center in Paraná, Brazil, and evaluated survival, immunosuppression, and transplant-related problems. METHODS: This study was a retrospective analysis of 131 SPK transplants performed at the Angelina Caron Hospital between January 2001 and December 2015...

BACKGROUND: Soluble CD30 (sCD30) is a suggested marker for kidney transplantation outcomes. We investigated whether sCD30 serum levels are influenced by immunosuppression and whether they correlate with findings in protocol biopsies and with CD30 gene expression in peripheral blood mononuclear cells (PBMC). METHODS: We studied 118 kidney transplant recipients that initially received tacrolimus (TAC) and, at month-3, were converted or not to sirolimus (SRL). RESULTS: sCD30 serum levels gradually declined after transplantation, being the decline more pronounced in the SRL group...

Sirolimus appears to protect against CMV in organ transplant recipients. The effect of this drug in allogeneic hematopoietic stem cell transplantation (allo-HSCT) recipients remains unexplored. By means of multivariate continuous-time Markov model analyses, we identified three independent covariates which significantly impacted the risk of CMV DNAemia: recipient/donor CMV serostatus, tacrolimus exposure and sirolimus exposure. CMV seropositive recipients with CMV seronegative donors had a significantly higher probability of having detectable CMV DNAemia...

Given the increasing incidence of chronic graft-versus-host disease (cGVHD) and its rapidly escalating costs due to many lines of drug treatments, we aimed to perform a meta-analysis to assess the comparative effectiveness of various treatment options. Using these results, we then conducted a cost-effectiveness analysis for the frequently utilized agents in steroid-refractory cGVHD. We searched for studies examining tacrolimus, sirolimus, rituximab, ruxolitinib, hydroxychloroquine, imatinib, bortezomib, ibrutinib, extracorporeal photopheresis, pomalidomide, and methotrexate...

A 27-year old caucasian male was diagnosed 2.7 years after kidney transplantation with Epstein-Barr virus (EBV)-associated smooth muscle tumors in liver and spleen. The reduction in immunosuppression and conversion from tacrolimus to sirolimus did not lead to a regression of the tumors. Additionally, the patient developed a cellular rejection of his renal allograft, which was successfully treated. A combined approach with stereotactic radiofrequency ablation (SRFA) and surgical resection was effective in the treatment of the tumors...

BACKGROUND: T- cell prolymphocytic leukemia (T- PLL) is a rare aggressive hematological malignancy. Alemtuzumab, an anti-CD52 humanized monoclonal antibody, is the treatment of choice for remission induction. Allogeneic hematopoietic cell transplantation (allo-HCT) has been described to induce durable remissions and improve survival, but data is limited. PATIENTS AND METHODS: We evaluated clinical outcomes of 11 patients, median age of 56 (range, 43-71) years who underwent allo-HCT for T-PLL...

There is currently no consensus on the most suitable therapeutic approach for psoriasis (PS) co-existing with posthepatic cirrhosis (PCs) and hepatocellular carcinoma (HCC) following liver transplantation (LT). The present study provides an analysis of the therapeutic experience of such patients. Five LT recipients (two with PC and three with HCC) with accompanying PS were included. The induction program consisted of methylprednisolone plus basiliximab treatment. The initial postoperative treatment scheme consisted of tacrolimus (FK506) plus mycophenolate mofetil (MMF) and hormone; the latter was withdrawn 1 week after LT...

Pericardial effusion in a renal transplant recipient represents a diagnostic conundrum with a variety of differential diagnoses. Immunosuppressive medications such as sirolimus have been linked to pericardial effusions in the reported literature. Tacrolimus has been reported to be associated with pleural effusions and ascites. We present a case of a patient with tacrolimus as the likely cause of a recurrent pericardial effusion.

Allogeneic blood or marrow transplantation (BMT) candidates may lack HLA-matched, related haploidentical, and unrelated umbilical cord options. Barriers to partially HLA-mismatched, unrelated donor (mMUD) BMT include excess graft-versus-host disease (GVHD), graft failure, and death. We prospectively studied nonmyeloablative (NMA) mMUD BMT with high-dose posttransplantation cyclophosphamide (PTCy) for patients with hematologic malignancies. Three transplants were performed with busulfan/fludarabine conditioning, with subsequent change to fludarabine/Cy/total body irradiation (flu/Cy/TBI)...
