Presently described is a case of disseminated adenovirus infection in a heart-kidney transplant recipient that was successfully treated with cidofovir. There are several reports of adenovirus infections in adult solid organ transplant recipients and the prognosis is usually poor, with mortality rates of 40% to 60%. Severe disseminated adenovirus infections have been associated with increased risk of adverse transplant events, such as rejection, ventricular dysfunction, allograft vasculopathy, graft loss, and the need for re-transplantation...

INTRODUCTION: Cytomegalovirus (CMV) infection is a relevant cause of morbidity and mortality in transplantation patients. Its major incidence is in the first year and viral replication is related to acute rejection, survival reduction, and graft vascular disease. OBJECTIVE: This study aims to evaluate retrospectively whether a high dose of calcineurin inhibitors correlates with CMV-positive polymerase chain reaction (PCR), need for treatment, and death in cardiac transplantation patients...

INTRODUCTION: In liver transplant (LT) patients, hepatitis E virus (HEV) can lead to acute liver failure, chronic hepatitis and graft cirrhosis. Few data on graft rejection associated with HEV are available and are subject to discussion. CASE REPORT: Here we report the case of a 58-year-old male patient who underwent LT in July 2015 for cirrhosis due to NASH and chronic alcohol intake complicated by hepatocellular carcinoma. LT was performed with a deceased donor isogroup and a mismatch CMV (donor+ and recipient-)...

Background: Major hurdles for survival after lung transplantation are rejections and infectious complications. Adequate methods for monitoring immune suppression status are lacking. Here, we evaluated quantification of torque teno virus (TTV) and Epstein-Barr virus (EBV) as biomarkers for defining the net state of immunosuppression in lung-transplanted patients. Methods: This prospective single-center study included 98 patients followed for 2 years after transplantation...

Bronchiolitis obliterans syndrome (BOS) remains the major problem which precludes long-term survival after lung transplantation. Previously, an open label pilot study from our group demonstrated a possible beneficial effect of montelukast in progressive BOS patients with low airway neutrophilia (<15%), and already on azithromycin treatment, in whom the further decline in pulmonary function was attenuated. This was, however, a non-randomized and non-placebo controlled trial. The study design is a single center, prospective, interventional, randomized, double blind, placebo-controlled trial, with a two arm parallel group design and an allocation ratio of 1:1...

BACKGROUND: Chronic kidney disease (CKD) is a growing global problem affecting around 10% of many countries' populations. Providing appropriate palliative care services (PCS) to those with advanced kidney disease is becoming paramount. Palliative/supportive care alongside usual CKD clinical treatment is gaining acceptance in nephrology services although the collaboration with and use of PCS is not consistent. METHODS: The goal of this study was to track and quantify the health service utilisation of people with CKD stages 3-5 over the last 12 months of life...

BACKGROUND: The progression from acute to chronic antibody-mediated rejection in kidney transplant recipients is usually not prevented by current therapeutic options. Here, we investigated whether the use of tofacinitib, a Janus kinase 3 inhibitor, was capable of preventing the progression of allograft dysfunction in a Fisher-to-Lewis rat model of kidney transplantation. METHODS: Rats were treated from the third week after transplantation in order to allow the development of rejection...

In the XXI century diabetes mellitus has become one of the main threats to human health with higher incidence in regions such as Europe and North America. Type 1 diabetes mellitus (T1DM) occurs as a consequence of the immune-mediated destruction of insulin producing β-cells located in the endocrine part of the pancreas, the islets of Langerhans. The administration of exogenous insulin through daily injections is the most prominent treatment for T1DM but its administration is frequently associated to failure in glucose metabolism control, finally leading to hyperglycemia episodes...

During the treatment of extracorporeal photopheresis (ECP), white blood cells are collected by apheresis and exposed to ultraviolet A after incubation with 8-methoxypsoralen. Although ECP was first developed for cutaneous T cell lymphoma, it has shown promising efficacy in a number of other serious conditions, like acute and chronic graft-versus-host disease, lung and cardiac transplant rejection and other autoimmune diseases. The ECP has been used for thirty years in some specialized centers but remains unknown to most of the physicians...

Extracorporeal life support and heart and/or lung transplant are the last resort in children with end-stage cardiac and/or pulmonary failure and short-term life threaten. Currently, circulatory support is used as a bridge to recovery or as a bridge to transplant but not as a destination therapy. The Excor Berlin Heart is the long-lasting external pneumatic ventricular assist system that is currently available from infancy to adulthood. Long-term prognosis after pediatric cardiac and/or pulmonary transplant is conditioned by the occurrence of graft failure, coronary disease of the cardiac graft, viral infections and bronchiolitis obliterans of the pulmonary graft, the incidence of which increase with time...

INTRODUCTION: Lung transplantation is the final treatment option in patients with respiratory failure. Morbidity and mortality rates associated with the management of complications is high despite advances. Postoperative complications include acute transplant rejection, bronchiolitis obliterans, and infections. Because of that, the success of this treatment option depends on the correct choice of donor and candidates to receive a transplant. OBJECTIVE: This study aims to perform a survival analysis of transplanted patients in our center and determine predictive variables of mortality...

BACKGROUND: Recurrent infection with the hepatitis C virus (HCV) after liver transplantation (LT) is associated with decreased graft and patient survival. Direct-acting antiviral (DAA) therapies have changed the landscape of HCV due to their excellent safety profile and cure rates. Our aim was to evaluate the efficacy and tolerability of antiviral therapy in recurrent HCV after LT with DAA therapy. METHODS: Our retrospective analysis included 46 LT recipients with HCV recurrence...

Despite significant progress in the field of transplant immunology, acute cellular rejection (ACR) remains a very frequent complication after lung transplantation (LTx), with almost 30% of LTx recipients experiencing at least one episode of treated ACR during the first year of follow-up. Most episodes respond to the first-line immunosuppressive treatment and are rarely a direct cause of death. However, the association of ACR with later adverse outcomes, such as chronic lung allograft dysfunction, bronchial stricture, and infectious complications associated with the intensification of immunosuppression, negatively impacts long-term survival...

Chronic-active antibody-mediated rejection (CAABMR) is associated with poor kidney graft survival and has no clear effective treatment. Forty-one cases of CAABMR were detected in indication graft biopsies and evaluated according to current Banff classification. We investigated the impact of concurrent donor-specific antibodies (DSA) and their characteristics, together with non-adherence regarding immunosuppression on CAABMR histopathological phenotypes and prognosis. Twenty-four (59%) patients had detectable DSA at biopsy, with 15 of them being considered non-adherent...

HLH occurring after HSCT is a relatively rare disease. Many conditions may mimic or trigger HLH in post-HSCT period (eg, cytokine release syndrome, engraftment syndrome, graft rejection/failure, acute graft-vs-host disease, infections systemic inflammatory response syndrome/sepsis, and thrombotic microangiopathy). Moreover, this period is usually marked by febrile illness, cytopenia, and a "cytokine storm" leading to elevation of inflammatory biomarkers like ferritin and sCD25. These parameters overlap with the diagnostic criteria for HLH...

Mucormycosis is an uncommonly encountered fungal infection in solid organ transplantation. The infection is severe and often results in a fatal outcome. The most common presentations are rhino-sino-orbital and pulmonary disease. We describe a rare case of gastric mucormycosis in a patient with a combined liver-kidney transplant affected by glycogen storage disease type Ia. A 42-year-old female patient presented with gastric pain and melena 26 days after transplantation. Evaluation with upper endoscopy showed two bleeding gastric ulcers...

BACKGROUND: Recent studies have demonstrated that IL-34 is implicated in the regulation of macrophage functions. However, the effect of IL-34 on Kupffer cells (KCs) in acute rejection (AR) of liver transplantation remains unclear. METHODS: IL-34 expression was detected in graft and serum from allotransplantation and syngeneic transplantation groups. The adeno-associated virus expressing IL-34 (AAV-IL-34) was used to assess the effect of IL-34 on AR of rat liver transplantation...

Immunosuppression after lung transplantation may increase susceptibility to opportunistic infection and is associated with early and delayed deaths in lung transplant recipients. Factors that may predispose lung transplant recipients to opportunistic bacterial and fungal infections include prolonged corticosteroid use, renal impairment, treatment of acute rejection, and post-transplant diabetes mellitus. We present a unique case of a 63-year-old woman with diabetes mellitus who underwent redo lung transplantation...
