Introduction Hepatitis C Virus (HCV) is a chronic infection of the liver and the leading cause of liver failure and liver transplantation worldwide. While prior HCV therapies were prolonged and had variable success rates, the advent of direct-acting antivirals (DAAs) has dramatically improved HCV therapy with minimal side effects, shorter treatment durations, and higher cure rates. Areas covered In this paper, we review the literature discussing the use of Vedroprevir (GS-9451) in treatment of HCV in a variety of patient populations...

BACKGROUND/AIM: Facial transplantation is a revolutionary procedure developed recently, which is indicated if autologous transfers fail to restore human appearance. More than 30 patients have undergone facial transplantation in different centers worldwide. Here, we provide an update on its main anatomical, surgical, immunological, ethical, and follow- up aspects. We also provide innovative perspectives of regenerative medicine and tissue engineering that could hold promise for this emerging surgical field...

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...

REVIEW
Noelle Frey
Chimeric Antigen Receptor (CAR) T cells that have been engineered to target CD19 have shown great promise in patients with relapsed and refractory B cell acute lymphocytic leukemia with remission rates of 70-90%. Some remissions have successfully bridged patients to a curable allogeneic stem cell transplant, some responses have been durable without further treatment, and some patients have achieved durable remissions for relapsed ALL after allogeneic stem cell transplant. Cytokine release syndrome, correlating with the in vivo activation and expansion of T cells, and neurologic toxicity are the most significant side effects and approaches to better understand and manage these events are the subject of ongoing clinical trials...

Immunotherapy has become one of the most promising avenues for cancer treatment, making use of the patient's own immune system to eliminate cancer cells. Clinical trials with T-cell-based immunotherapies have shown dramatic tumor regressions, being effective in multiple cancer types and for many different patients. Unfortunately, this progress was tempered by reports of serious (even fatal) side effects. Such therapies rely on the use of cytotoxic T-cell lymphocytes, an essential part of the adaptive immune system...

BACKGROUND: Permanent hypoparathyroidism is a serious problem and requires medications indefinitely. Parathyroid allotransplantation (PA) with short-term immunosuppression is definitive choice but long-term results are not clear. METHOD: We performed PA from two donors to two recipients. Both recipients were 39-year-old females. Donors were a 32-year-old female and a 36-year-old male, who both have chronic kidney disease. Routine tests, viral markers, and cross-matches were analyzed individually...

This article focuses on the unconventional treatments used in chronic inflammatory demyelinating polyneuropathy (CIDP). First line, evidence-based treatments for CIDP include corticosteroids, immunoglobulins and plasma exchanges. Several unproven treatments are however given in treatment-refractory disease or to reduce requirements in validated therapies for reasons of side effects/practical delivery/cost. Despite methodological issues, IFN-α, azathioprine and methotrexate have not been shown to be useful in randomized controlled trials...

Patients who undergo corrective surgery for cleft lip are known to be at risk for subsequently developing secondary nasal deformity. The aim of this study was to investigate the effects of Y-shaped conchal cartilage transplantation on the correction of nasal deformity secondary to cleft lip and its influence on mental health. Sixteen patients with nasal deformity secondary to cleft lip admitted to The First People's Hospital Xuzhou (Xuzhou, China) from February 2014 to February 2015 were selected for the study...

BACKGROUND: Cryopreserved hematopoietic progenitor cell (HPC) grafts are widely infused to patients with malignant and nonmalignant conditions. Despite reduction of immediate side effects linked to dimethyl sulfoxide (DMSO), cell debris-containing grafts and comparable hematopoietic engraftment between washed and unwashed cryopreserved products, bedside infusion of thawed HPC grafts is still preferred. Introduction of automated devices is important for standardization and consistency of graft manipulation...

BACKGROUND: Urea cycle disorders (UCDs) still have a poor prognosis despite several therapeutic advancements. As liver transplantation can provide a cure, liver cell therapy (LCT) might be a new therapeutic option in these patients. METHODS: Twelve patients with severe UCDs were included in this prospective clinical trial. Patients received up to six infusions of cryopreserved human heterologous liver cells via a surgically placed catheter in the portal vein. Portal vein pressure, portal vein flow, and vital signs were monitored continuously...

Adipose-derived mesenchymal stem cells (ASCs) have been shown to produce vascular endothelial growth factor (VEGF) and can increase perfusion in patients with critical limb ischemia. We will show that this concept can be applied to augment blood flow in zones of flap ischemia. We presented a case study of a 26-year-old man with a complex hand injury covered by a reverse radial perforator fasciocutaneous flap, which developed ischemic necrosis and was treated by debridement, transplantation of ASCs to enhance vascular support, and saline dressings...

The activation of β-cell's A- and B-type gamma-aminobutyric acid receptors (GABAA-Rs and GABAB-Rs) can promote their survival and replication, and the activation of α-cell GABAA-Rs promotes their conversion into β-cells. However, GABA and the most clinically applicable GABA-R ligands may be suboptimal for the long-term treatment of diabetes due to their pharmacological properties or potential side-effects on the central nervous system (CNS). Lesogaberan (AZD3355) is a peripherally restricted high-affinity GABAB-R-specific agonist, originally developed for the treatment of gastroesophageal reflux disease (GERD) that appears to be safe for human use...

Integrase strand transfer inhibitors (INSTIs) are the preferred third agent in first-line antiretroviral therapies. Raltegravir (RAL) was the first INSTI to be approved and used in naïve and experienced patients. Due to its good tolerability and low side effects, RAL has been largely used also in hepatitis co-infected patients. Many years of experience in RAL use now allow literature evidence to be gathered on its safety in HIV/HCV-co-infected patients pre, during and post direct acting agents (DAA) treatment, at all possible stages...

Background: Primary focal segmental glomerulosclerosis (FSGS) frequently recurs after kidney transplantation (KTx) in children. This can lead to delayed graft loss. As the management of children with recurrent FSGS is not well established, apheresis strategies could be a cornerstone to control the disease. Immunoadsorption (IA) is a recent apheresis therapy. There have been few studies examining IA in this setting. We report the results of IA for management of recurrent FSGS after KTx in children in France...

Post-transplant diabetes mellitus (PTDM) is common after most types of solid organ transplantation, though the actual incidence is as yet unknown because of the use of different diagnostic criteria. PTDM is the result of individual risk factors as well as risk factors associated with the transplant itself, particularly immunosuppressants. Previously called New Onset Diabetes, in many cases inadequate screening for diabetes before transplant cannot assure that the diabetes is new after transplant. The most recent international consensus guidelines suggest diagnosis should be delayed until the patient is taking maintenance doses of immunosuppressants even if they require treatment in the immediate hospitalization...

BACKGROUND: Immunosuppressive therapies derived from solid organ transplantation are effective in promoting survival of vascularized composite allotransplantation (VCA), but they cause serious side effects that are difficult to justify for this non-life-saving procedure. Unlike solid organ transplantation, hand and face transplants offer the possibility of site-specific immunosuppression for reducing systemic exposure while increasing intra-graft concentrations of the drug. Therefore, in this study, we tested whether a single intra-graft injection tacrolimus could promote VCA survival...

Joanne M Bowen, Hannah R Wardill
PURPOSE OF REVIEW: Mucositis is a severe and common side effect of anticancer treatments, with an incidence of between 40 and 80% depending on the cytotoxic regimen used. The most profound mucositis burden is experienced during conditioning regimens for hematopoietic stem cell transplant (HSCT), where the use of highly mucotoxic agents with or without total body irradiation leads to serious damage throughout the alimentary tract. Currently, the assessment and management of both oral and gastrointestinal mucositis lack authoritative guideline, with recommendations only achieved in narrow clinical scenarios...

BACKGROUND: Pharmacokinetic data show reduced mycophenolic acid levels in renal transplant recipients taking mycophenolate mofetil (MMF) and proton pump inhibitors (PPIs) concomitantly. This reduced exposure could increase rejection risk. The typical initial MMF dose post-renal transplant is 2 g daily, which often requires dose reduction secondary to side effects. Existing studies have not shown significant acute rejection differences for patients taking MMF-PPI versus MMF-ranitidine...
