This study assessed adherence to prolonged-release tacrolimus (PR-T)-based immunosuppression during routine maintenance of renal transplant recipients in Germany. Patients had received PR-T for ≥1 month at inclusion. Data were collected during four visits (V): baseline (V1), 6 (V2), 12 (V3) and 18 (V4) months. Composite primary endpoint: non-adherence at V4, defined as self-reported non-adherence on the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS©), investigator-rated non-adherence, and/or V4 tacrolimus trough level outside a pre-defined range...

Allogeneic hematopoietic stem cell transplantation (HSCT) is the recommended treatment for children with very high risk acute lymphoblastic leukemia (ALL), but it requires adequate institutional infrastructure, experience, and expertise, especially for alternative donor HSCT. We review our experience with high-dose chemotherapy (HDCT) and autologous peripheral blood stem cell transplantation (APBSCT), followed by post-APBSCT maintenance chemotherapy for children with very high risk ALL. Between August 1997 and November 2012, our institute was not successful with HLA-haploidentical HSCT...

Imatinib has clinical activity in chronic graft-versus-host disease (cGvHD), a significant complication of allogeneic hematopoietic cell transplant. Nilotinib is a tyrosine kinase inhibitor that targets the same receptors as imatinib but with different affinities. We tested the hypothesis that nilotinib is safe and has clinical activity in cGvHD. 33 participants were enrolled in a phase 1/2 dose escalation and dose extension clinical trial of nilotinib for the treatment of steroid refractory or dependent cGvHD (ClinicalTrials...

Nelarabine, a water soluble prodrug of 9-β-D-arabinofuranosylguanine (ara-G), is a T-cell specific purine nucleoside analogue. Given its activity in relapsed and refractory T acute lymphoblastic leukemia (T-ALL) and T lymphoblastic lymphoma (T-LBL), we sought to define its role in the frontline treatment of adult patients. Therefore, we conducted a single arm phase 2 study to determine the safety and efficacy of nelarabine in combination with hyper-CVAD in newly diagnosed patients. For induction/consolidation, patients received eight cycles of hyper-CVAD alternating with high-dose methotrexate and cytarabine plus two cycles of nelarabine given at a dose of 650 mg/m(2) intravenously daily for 5 days...

Cellular therapies based on permanent genetic modification of conventional T cells have emerged as a promising strategy for cancer. However, it remains unknown if modification of T cell subsets, such as Tregs, could be useful in other settings, such as allograft transplantation. Here, we use a modular system based on a chimeric antigen receptor (CAR) that binds covalently modified mAbs to control Treg activation in vivo. Transient expression of this mAb-directed CAR (mAbCAR) in Tregs permitted Treg targeting to specific tissue sites and mitigated allograft responses, such as graft-versus-host disease...

It is currently controversially discussed whether mesenchymal stem cells (MSC) facilitate cartilage regeneration in vivo by a progenitor- or a nonprogenitor-mediated mechanism. Here, we describe a potentially novel unbiased in vivo cell tracking system based on transgenic donor and corresponding immunocompetent marker-tolerant recipient mouse and rat lines in inbred genetic backgrounds. Tolerance of recipients was achieved by transgenic expression of an immunologically neutral but physicochemically distinguishable variant of the marker human placental alkaline phosphatase (ALPP)...

Specialist species are more vulnerable to environmental change than generalist species. For species with ontogenetic niche shifts, specialization may occur at a particular life stage making those stages more susceptible to environmental change. In the salt marshes in the northeast U.S., accelerated sea level rise is shifting vegetation patterns from flood-intolerant species such as Spartina patens to the flood-tolerant Spartina alterniflora. We tested the potential impact of this change on the coffee bean snail, Melampus bidentatus, a numerically dominant benthic invertebrate with an ontogenetic niche shift...

Indoleamine 2,3 dioxygenase-1 (IDO-1) is an enzyme in the kynurenine pathway which augments tumor-induced immune tolerance. Previous studies in childhood acute myeloid leukemia (AML) have shown a negative correlation of IDO-1 mRNA expression with outcomes. The aim of our study was to develop a practical and objective immunohistochemical technique to quantify IDO-1 expression on diagnostic bone marrow biopsies of AML patients in order to facilitate its use in routine clinical practice. IDO-1 mRNA was extracted from diagnostic bone marrow specimens from 29 AML patients...

The involvement of effector T cells and regulatory T (T reg) cells in opposing and promoting solid organ carcinogenesis, respectively, is viewed as a shifting balance between a breach versus establishment of tolerance to tumor or self-antigens. We considered that tumor-associated T cells might promote malignancy via distinct mechanisms used by T cells in nonlymphoid organs to assist in their maintenance upon injury or stress. Recent studies suggest that T reg cells can participate in tissue repair in a manner separable from their immunosuppressive capacity...

REVIEW

Hepatocellular carcinoma (HCC) recurrence rate after liver transplantation (LT) is still up to 15-20%, despite a careful selection of candidates and optimization of the management within the waiting list. To reduce tumour recurrence, the currently adopted post-transplant strategies are based on the administration of a tailored immunosuppression (IS) regimen. Drug-induced depression of the immune system is essential in preventing graft rejection, however has a well-established association with oncogenesis. The immune system has a key role as a defending mechanism against cancer development, preventing vascular invasion and metastasis...

Violeta Furlan, María L Pochettino, Norma I Hilgert
Home gardens are considered germplasm repositories and places for experimentation, thus they are key sites for the domestication of plants. Domestication is considered a constant process that occurs along a continuum from wild to managed to domesticated populations. Management may lead to the modification of populations and in other cases to their distribution, changing population structure in a landscape. Our objective is focused on the management received in home gardens by perennial species of fruits. For this, the management practices applied to native and exotic perennial fruits species by a group of 20 women in the periurban zone of Iguazú, Argentina, were analyzed...

To evaluate the pharmacokinetic (PK) and tolerability profiles of a new tablet formulation of tacrolimus and its interindividual variability (IIV) in the systemic exposure, and to compare them with those of the conventional capsule formulation, a randomized, open-label, two-treatment, two-period, two-sequence, crossover study was performed in 47 healthy males. The capsule or tablet formulation of tacrolimus was orally administered, and serial blood samples were collected up to 96 hours after dosing. Whole-blood tacrolimus concentration was determined using liquid chromatography-tandem mass spectrometry...

BACKGROUND CML presenting with a variant Philadelphia translocation, atypical BCR-ABL transcript, additional chromosomal aberrations, and evolving MDS is uncommon and therapeutically challenging. The prognostic significance of these genetic findings is uncertain, even as singular aberrations, with nearly no data on management and outcome when they coexist. MDS evolving during the course of CML may be either treatment-associated or an independently coexisting disease, and is generally considered to have an inferior prognosis...

Graft rejection (GR) following an allo-SCT occurs in 10-20% of patients with β thalassemia major (TM). There is limited data on the clinical profile and long term outcome of patients who have had a graft rejection. We undertook a retrospective analysis of patients who had a graft failure post allogeneic SCT for TM at our center. From October, 1991 to June 2016, 55/506 (11%) patients transplanted for TM had a graft failure. An additional 7 patients with graft failure following an allo-SCT done at other centers were referred to us for a second transplant...

BACKGROUND: Reduced intensity conditioning regimens (RIC) for hematopoietic stem cell transplantation (HCT) can reduce morbidity and mortality, but patients with advanced disease may require alternate approaches. In an initial report of RIC (Fludarabine (FLU) and Melphalan (MEL)) with total-marrow-lymphoid irradiation (TMLI) in HCT for advanced hematological malignancies in 33 patients, we found the addition of TMLI to RIC was feasible and safe. Here we report long-term outcomes for these patients...

INTRODUCTION: No standard salvage chemotherapy regimen is available for relapsed or refractory (RR) acute myeloid leukemia (AML). Preclinical data have suggested synergy in vitro between cytarabine and imatinib mesylate (IM) on AML cell growth inhibition. After demonstrating the safety and feasibility in a phase I study, we conducted a phase II clinical study of CLAG (cladribine, cytarabine, granulocyte colony-stimulating factor) regimen combined with IM for patients with RR-AML. PATIENTS AND METHODS: We performed a single-institution 2-stage phase II study...

Antiprogrammed cell-death protein 1 (PD-1) antibodies have revolutionized therapy of metastatic melanoma and other tumors, but some subgroups of patients such as immunosuppressed patients after solid-organ transplantation, have regularly been excluded from clinical studies. We report 2 cases of kidney-transplant patients who received an anti-PD-1 antibody to treat metastatic melanoma. Treatment was tolerated well with no relevant adverse events and stable kidney functions, but the melanoma progressed in both patients...

Anthropogenic carbon dioxide (CO2) emissions and consequent ocean acidification (OA) are projected to have extensive consequences on marine calcifying organisms, including corals. While the effects of OA on coral calcification are well documented, the response of reproduction is still poorly understood since no information are reported for temperate corals. Here we investigate for the first time the influence of OA on sexual reproduction of the temperate azooxanthellate solitary scleractinian Leptopsammia pruvoti transplanted along a natural pCO2 gradient at a Mediterranean CO2 vent...
