Ischemia-reperfusion injury, a form of sterile inflammation, is the leading risk factor for both short-term mortality following pulmonary transplantation and chronic lung allograft dysfunction. While it is well recognized that neutrophils are critical mediators of acute lung injury, processes that guide their entry into pulmonary tissue are not well understood. Here, we found that CCR2+ classical monocytes are necessary and sufficient for mediating extravasation of neutrophils into pulmonary tissue during ischemia-reperfusion injury following hilar clamping or lung transplantation...

BACKGROUND: Although, presence of donor specific antibodies (DSA) is known to impact lung allograft, limited data exists regarding DSA management. METHODS: We did a retrospective study at our center evaluating DSA management in adult lung transplant recipients undergoing lung transplantation between January 1, 2010 and June 30, 2014. Study follow up was completed through October 2017. All recipients were stratified into two groups based on the presence or absence of DSA...

Chronic lung allograft dysfunction (CLAD) with its clinical correlative of bronchiolitis obliterans syndrome (BOS) remains the major limiting factor for long-term graft survival. Currently there are no established methods for the early diagnosis or prediction of BOS. To assess the feasibility of breath collection as a non-invasive tool and the potential of breath volatile organic compounds (VOC) for the early detection of BOS, we compared the breath VOC composition between transplant patients without and different stages of BOS...

Chronic kidney disease is most desirably and cost-effectively treated by renal transplantation, but graft survival is a major challenge. Although irreversible graft damage can be averted by timely treatment, intervention is delayed when early graft dysfunction goes undetected by standard clinical metrics. A more sensitive and specific parameter for delineating graft health could be the viscoelastic properties of the renal parenchyma, which are interrogated non-invasively by Viscoelastic Response (VisR) ultrasound, a new acoustic radiation force (ARF)-based imaging method...

INTRODUCTION: Lung retransplantation is an important therapy for a growing population of lung transplant recipients with graft failure, but detailed outcome data are lacking. METHODS: We conducted a retrospective cohort study of adult lung retransplant in the Toronto Lung Transplant Program from 2001 to 2013 (n=38). We analyzed the post-operative course, graft function, renal function, microbiology, donor specific antibodies (DSA), quality of life and survival compared to a control cohort of primary transplant recipients matched for age and era...

Under current immunosuppressive regimes, T-cell-mediated acute and chronic rejection remain common and important posttransplant complications. The definition of humoral (antibody-mediated) rejection has been greatly expanded in recent years. The histopathologic assessment of allograft biopsies continues to serve an important role in the diagnosis of rejection and to facilitate patient management. The diagnosis of both acute and chronic antibody-mediated rejection requires integration of the results of donor-specific antibody testing and C4d immunostaining, as well as exclusion of other potential etiologies of allograft dysfunction...

This retrospective study presents our 4-year experience of preemptive treatment of early anti-HLA donor specific antibodies with IgA- and IgM-enriched immunoglobulins. We compared outcomes between patients with antibodies and treatment (case patients) and patients without antibodies (control patients). Records of patients transplanted at our institution between 03/2013 and 11/2017 were reviewed. The treatment protocol included one single 2g/kg immunoglobulin infusion followed by successive 0.5g/kg infusions for a maximum of 6 months, usually combined with a single dose of anti-CD20 antibody and, in case of clinical rejection or positive crossmatch, with plasmapheresis or immunoabsorption...

Acute kidney injury (AKI) after liver transplantation (LT) is a common event, but its pathogenesis remains unclear. The aim of this prospective study is to investigate the potential relationship between post-reperfusion gene expression, serum mediators, and the onset of AKI after LT. Sixty-five consecutive patients undergoing LT were included in the study. Reverse transcription polymerase chain reaction (RT- PCR), was performed on liver biopsies. Gene expression of 23 genes involved in ischemia reperfusion injury (IRI) was evaluated...

Antibody-mediated rejection (ABMR) is a major cause of late renal allograft dysfunction and graft loss. Risks and benefits of treatment of late ABMR have not been evaluated in randomized clinical trials. We report on a 35-year-old patient with deterioration in renal function and progressive proteinuria 15 years after transplantation. Recurrent infections after a splenectomy following traumatic splenic rupture 3 years earlier had led to reduction of immunosuppression. Renal transplant biopsy showed glomerular double contours, 40% fibrosis/tubular atrophy, peritubular capillaritis, and positive C4d staining indicating chronic-active ABMR...

RATIONALE: Chronic lung allograft dysfunction is the biggest impediment to long-term survival after lung transplantation. Studies have shown an increased risk for chronic lung allograft dysfunction in patients exposed to traffic-related air pollution, using residential distance to roadways and outdoor pollution. OBJECTIVES: Personal monitoring and the indoor environment post-lung transplantation have not been investigated. The exposome is a novel conceptual framework that allows for concurrent examination of multiple intrinsic and extrinsic factors, including environmental exposures, as well as changes in exposures over time, to elucidate the complex environmental factors that affect health outcomes...

BACKGROUND Correction of hypovitaminosis D is simple, but it is unclear whether it is associated with an accelerated decline of renal allograft function in pediatric renal transplantation patients. This retrospective single center cohort study aimed at analyzing the effect of vitamin D and covariates on the slope of 1/creatinine after the first year. MATERIAL AND METHODS After ethics committee approval, 37 (14 male) pediatric renal transplant recipients on mycophenolate mofetil, who were followed between 2006 and 2014, were included in this study...

BACKGROUND: Due to its multisystemic nature, scleroderma is considered a relative contraindication to lung transplantation at many centers. However, recent studies suggest similar post-transplant outcomes in patients with scleroderma compared to those with other causes of interstitial lung disease (ILD). Furthermore, it remains unknown whether scleroderma-associated pulmonary arterial hypertension (PAH) influences post-transplant outcomes. Our objective in this study was to assess the indications, survival, and prognostic factors of lung or heart-lung transplantation for scleroderma lung disease...

In the context of limited donor pool in cardiothoracic transplantation, utilization of organs from high risk donors, such as suicidal hanging donors, while ensuring safety, is under consideration. We sought to evaluate the outcomes of lung transplantations (LTx) that use organs from this group.Between January 2011 and December 2015, 265 LTx were performed at our center. Twenty-two recipients received lungs from donors after suicidal hanging (group 1). The remaining 243 transplantations were used as a control (group 2)...

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...

Chronic lung allograft dysfunction (CLAD) remains the leading cause of morbidity and mortality after lung transplantation. Diagnosis requires spirometric change, that becomes increasingly difficult with advancing CLAD. Fourier decomposition MRI (FD-MRI) permits acquisition of ventilated-weighted images during free-breathing. This study evaluates FD-MRI in detecting CLAD in selected patients after bilateral lung transplantation (DLTx). DLTx recipients demonstrating CLAD at various stages participated. Radiologists remained blinded to clinical status until completion of image analysis...

BACKGROUND: Cytomegalovirus (CMV) disease has been associated with the development of chronic lung allograft dysfunction (CLAD) after transplantation. However, the relevance of CMV replication occurring after the discontinuation of antiviral prophylaxis on the development of CLAD has not been fully established. METHODS: Patients who underwent lung transplantation during 2004-2014 were included. All patients received antiviral prophylaxis for 3-6 months, followed by monitoring of CMV replication during the first year post-transplantation (preemptive therapy)...

Primary graft dysfunction (PGD) is a form of acute lung injury that results from ischemia reperfusion injury (IRI) and is the major cause of early posttransplant morbidity and mortality. Patients who survive PGD have decreased quality of life, an increased risk of chronic lung allograft dysfunction, specifically bronchiolitis obliterans syndrome, and a significantly increased risk of death. In 2017, the International Society for Heart and Lung Transplantation released updated consensus statements on the PGD definition, most up-to-date PGD risk factors, mechanisms of PGD development, and the state-of-the-art for PGD therapeutics...

There is currently no way to diagnose a rejection before a change in serum creatinine. This had led some to start doing SB, but little data exist on the utility and safety of SB in pediatric patients. There is also little known on practice patterns of pediatric nephrologists. A retrospective review of pediatric kidney transplant SB between January 2013 and January 2017 at a single center was performed. A survey went to the PedNeph email list. There were 47 SB; 15 at 6 months, 12 at 1 year, 13 at 2 years, and 7 at 3 years...

Chronic renal allograft dysfunction (CRAD) is the primary factor affecting the long-term survival of patients who have undergone renal transplantation. Oxidative stress and inflammation serve an important role in the pathological damage caused by CRAD in the early post-transplantation phase. Previous studies have demonstrated that sirtuin 3 (sirt3) protects cells from oxidative stress and inflammation. A model of renal orthotopic transplantation was established in the current study and kidney samples were harvested from the rats 12 weeks following surgery...
