Survival in children with relapsed/refractory acute myeloid leukemia is unsatisfactory. Treatment consists of one course fludarabine, cytarabine and liposomal daunorubicin, followed by fludarabine and cytarabine and stem-cell transplantation. Study ITCC 020/I-BFM 2009-02 aimed to identify the recommended phase 2 dose of clofarabine replacing fludarabine in the abovementioned combination regimen (3+3 design). Escalating dose-levels of clofarabine (20-40mg/m2/day x5days) and liposomal daunorubicin (40-0mg/m2/day) were administered with cytarabine (2g/m2/day x5days)...

In France, endothelial dysfunction represents approximately one half of the indications for corneal transplants performed each year. However, the use of endothelial keratoplasty is limited by the technical difficulty of the procedure, a shortage of available grafts, and the potential for graft failure or rejection. These limitations are driving researchers to develop new, less invasive, and more effective therapies. Corneal endothelial cell therapy is being explored as a potential therapeutic measure, to avoid the uncertainty associated with grafting...

BACKGROUND: Herein, we report a case of systemic cutaneous T-cell lymphoma refractory to standard therapy, the course of which resulted in haplo-identical bone marrow grafting. PATIENTS AND METHODS: A 53-year-old woman consulted for facial erythema with infiltration, keratotic lesions on the trunk, and adenopathies measuring around 1cm on the axilla and inguinal folds. A diagnosis was made of Sézary syndrome (SS), a leukaemic form of epidermotropic cutaneous T-cell lymphoma...

PURPOSE OF REVIEW: The aim of this study was to highlight recent evidence on important aspects of influenza vaccination in solid organ transplant recipients. RECENT FINDINGS: Influenza vaccine is the most evaluated vaccine in transplant recipients. The immunogenicity of the vaccine is suboptimal after transplantation. Newer formulations such as inactivated unadjuvanted high-dose influenza vaccine and the administration of a booster dose within the same season have shown to increase response rates...

BACKGROUND: Although trough levels of immunosuppressive drugs are largely used to monitor immunosuppressive therapy after solid organ transplantation, there is still no established tool that allows for a validated assessment of functional degree of immunosuppression or the identification of clinically relevant over- or under-immunosuppression, depending on graft homeostasis. Reliable non-invasive markers to predict biopsy proven acute rejection (BPAR) do not exist. Literature data suggest that longitudinal measurements of immune markers might be predictive of BPAR, but data in children are scarce...

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall...

OBJECTIVES: The goal of this study was to determine the long-term outcomes of catheter ablation (CA) of electrical storm in patients with nonischemic dilated cardiomyopathy (NIDCM) compared with patients with ischemic cardiomyopathy (ICM). BACKGROUND: CA of ventricular tachycardia (VT) electrical storm has been shown to improve VT-free survival in patients with ICM. Data on the outcomes of CA of electrical storm in patients with NIDCM are insufficient. METHODS: The study included 267 consecutive patients with NIDCM (n = 71; ejection fraction 32 ± 14%) and ICM (n = 196; ejection fraction 28 ± 12%)...

We conducted a phase I study of brentuximab vedotin (BV), an antibody-drug conjugate targeting CD30, for the treatment of steroid-refractory chronic graft-versus-host disease (cGVHD). A modified 3+3 study design was used with the primary endpoint to determine the maximum tolerated dose (MTD) of BV in this population. Escalating doses of BV were planned, starting with 0.6 mg/kg q3weeks (dose level 0) and increasing by 0.3 mg/kg per dose level. BV was administered in 21-day cycles for up to 16 cycles of therapy...

Waitlist time for kidney transplantation is long but may be shortened with the utilization of hepatitis C positive allografts. We retrospectively reviewed the course of 36 hepatitis C positive patients awaiting kidney transplantation at two large centers within the same health system, with near-identical care delivery models with the exception of timing of hepatitis C treatment, to determine the impact of timing of hepatitis C treatment on access to transplant, waitlist time and treatment efficacy and tolerability...

Background: Current reliance on clinical, laboratory and Doppler ultrasound (DUS) parameters for monitoring kidney transplant perfusion in the immediate post-operative period in children risks late recognition of allograft hypoperfusion and vascular complications. Near-infrared spectroscopy (NIRS) is a real-time, non-invasive technique for monitoring tissue oxygenation percutaneously. NIRS monitoring of kidney transplant perfusion has not previously been validated to the gold standard of DUS...

The incidence of most hematologic malignancies increases with age. Physicians increasingly refer older patients for hematopoietic stem cell transplantation (HSCT) due to more experience and improved supportive care in HSCT. This article discusses the available data regarding the feasibility, tolerability, toxicity, and effectiveness of autologous and allogeneic HSCT in older adults.

Heme oxygenase-1 (HO-1) is a major anti-inflammatory enzyme and a key regulator that induces immune tolerance through affecting the differentiation of dendritic cells. The aim of this study is to determine whether the combination of 5-aminolevulinic acid (ALA) and iron induces HO-1 expression in healthy human peripheral blood mononuclear cells (PBMC). The study was an open labeled, non-randomized, non-placebo-controlled trial using healthy male adults and consisted of three parts. Study A aimed to find the peak HO-1 expression at 0, 1, 2, 3, 4, 6, 8, 12, 16, and 24h after administration...

The development of T cell tolerance in the thymus requires the presentation of host proteins by multiple antigen-presenting cell (APC) types. However, the importance of transferring host antigens from transcription factor AIRE-dependent medullary thymic epithelial cells (mTECs) to bone marrow (BM) APCs is unknown. We report that antigen was primarily transferred from mTECs to CD8α+ dendritic cells (DCs) and showed that CD36, a scavenger receptor selectively expressed on CD8α+ DCs, mediated the transfer of cell-surface, but not cytoplasmic, antigens...

Regulatory T cells (Tregs) are essential for the maintenance of tolerance and immune homeostasis. In allogeneic hematopoietic stem cell transplantation (aHSCT), transfer of appropriate Treg numbers is a promising therapy for the prevention of graft-versus-host disease (GVHD). We have recently reported a novel approach which induces the marked expansion and selective activation of Tregs in vivo by targeting TNF receptor superfamily 25 (TNFRSF25) and CD25. A potential advance to promote clinical application of Treg cells to ameliorate GVHD and other disorders would be the generation of more potent Treg populations...

Recurrent/refractory hematologic malignancies have a poor prognosis, and there is a need for novel treatment regimens that can be tolerated by this heavily pretreated patient group. Clofarabine has antileukemic activity with an acceptable toxicity profile. In a phase I clinical trial (NCT00824135), we substituted clofarabine for fludarabine in a well-established reduced-intensity conditioning regimen for a T cell-depleted, mismatched-related (haploidentical) donor transplant backbone and explored the maximum tolerated dose of clofarabine in this combination in 15 patients undergoing hematopoietic cell transplantation for recurrent/refractory or secondary leukemia...

Alcohol abstinence is the most important therapeutic goal for individuals with advanced liver disease (ALD), but commonly co-occurring alcohol use disorders (AUD) make it difficult to achieve (DiMartini et a, 2004). This challenge is perhaps best documented in the pre- and post-liver transplant period: around 30% of patients on a liver transplant list relapse with alcohol (Carboneau et al., 2010), and up to 50% can relapse in the first 10 years post-transplant (DiMartini et al., 2010). Tools to assist patients with ALD and AUD in initiating and maintaining abstinence have been limited: safe, tolerable, and effective pharmacotherapies for AUD are not widely used and treatment is often complicated by medical issues including malnourishment, physically debility, covert or overt hepatic encephalopathy, sleep and fatigue disorders, comorbid depression, and anxiety disorders...

Jellyfish green fluorescent protein (GFP) and firefly luciferase can serve as versatile tracking markers for identification and quantification of transplanted cancer cells in vivo. However, immune reactions against these markers can hamper the formation of syngraft tumors and metastasis that follows. Here, we report two transgenic (Tg) mouse lines that express nonfunctional mutant marker proteins, namely modified firefly luciferase (Luc2) or enhanced GFP (EGFP). These mice, named as Tg-mLuc2 and Tg-mEGFP, turned out to be immunologically tolerant to the respective tracking markers and thus efficiently accepted syngeneic cancer cells expressing the active forms of the markers...
