BACKGROUND: Idiopathic hyperammonemia syndrome (IHS) is an uncommon, often deadly complication of solid organ transplantation. IHS cases in solid organ transplantation seem to occur predominantly in lung transplant (LTx) recipients. However to the best of our knowledge the occurrence of IHS has not been systematically evaluated. We set out to identify all reported cases of IHS following non-liver solid organ transplantations. METHODS: Retrospective review of our institutional experience and systematic review of the literature...

OBJECTIVE: The aim of this single-centre, cross-sectional study was to evaluate dental, periodontal and mycological findings, as well as oral behaviour, in patients before (pre-LTx) and after (post-LTx) liver transplantation. METHODS: A total of 47 patients pre-LTx and 119 patients post-LTx were asked to participate. Oral health behaviour was assessed using a standardised questionnaire. Oral examinations included dental [decayed, missing and filled teeth (DMFT) index] and periodontal [papillary bleeding index (PBI), periodontal probing depth (PPD) and clinical attachment loss (CAL)] findings...

BACKGROUND: This study compared therapeutic azole plasma trough levels (APL) of the azole antimycotics itraconazole (ITR), voriconazole (VOR), and posaconazole (POS) in lung transplant recipients and analyzed the influencing factors. In addition, intrapatient variability for each azole was determined. METHODS: From July 2012 to July 2015, 806 APL of ITR, VOR, posaconazole liquid (POS-Liq), and posaconazole tablets (POS-Tab) were measured in 173 patients of the Munich Lung Transplantation Program...

AIM: To systematically review reports on deceased-donor-lobar lung transplantation (ddLLTx) and uniformly describe size matching using the donor-to-recipient predicted-total lung-capacity (pTLC) ratio. METHODS: We set out to systematically review reports on ddLLTx and uniformly describe size matching using the donor-to-recipient pTLC ratio and to summarize reported one-year survival data of ddLLTx and conventional-LTx. We searched in PubMed, CINAHL via EBSCO, Cochrane Database of Systematic Reviews via Wiley (CDSR), Database of Abstracts of Reviews of Effects via Wiley (DARE), Cochrane Central Register of Controlled Trials via Wiley (CENTRAL), Scopus (which includes EMBASE abstracts), and Web of Science for original reports on ddLLTx...

Fiberoptic bronchoscopy and transbronchial lung biopsy are currently the gold standard for detection of acute rejection following human lung transplantation (LTx). However, these surveillance procedures are expensive and invasive. Up to now, there are few new methods that have demonstrated clinical utility for detecting early stages of rejection following human lung transplantation. We optimized and technically validated a novel method to quantify donor-derived circulating cell free DNA (DcfDNA) that can be used as an early biomarker for lung allograft rejection...

BACKGROUND This study investigated the protective effects of pharmaceutical CD26/dipeptidylpeptidase-4 (CD26/DPP-4) inhibitor in lung transplantation (LTx). Changes in protein expression associated with the treatment were screened and identified to evaluate the role of kininogen-1 in early-term ischemia/reperfusion (I/R) injury after LTx. MATERIAL AND METHODS Orthotopic single LTx was performed in syngeneic C57BL/6 mice, with a pharmaceutical CD26/DPP-4 inhibitor (vildagliptin, subcutaneous injection, 10 mg/kg, every 12 h) administered to the investigational group...

BACKGROUND: Donation after cardiac death (DCD) to overcome the donor organ shortage is well accepted in the clinical setting, although long-term outcome after DCD lung transplantation (LTx) remains largely unknown. METHODS: In this retrospective study, DCD LTx recipients (n=59) were compared with a cohort of donation after brain-death (DBD) LTx recipients (n=331) transplanted between February 2007 and September 2013; follow-up was until January 1st 2016. Short-term (duration of mechanical ventilation, ICU stay, hospital stay and highest PGD score within 72 hours) and long-term (CLAD-free and overall survival) follow-up were compared over a median follow-up of 50...

While reduced HRQOL following isolated organ transplantation has been previously reported, there are no data in the context of children following CLKT. Twenty-three children who underwent CLKT at our institution were included in the study. The indication for CLKT was PH1 in 13 patients and ARPKD in 10 patients. Quantification of HRQOL was facilitated through the use of the PedsQL 4.0 Generic Core Scale. The results of the study were compared to healthy children and published data of children who had undergone LTx or KTx...

Post-transplantation mortality after lung transplantation (LTX) is higher than for other solid organ transplantations. Thoracic surgery is associated with increased risk of thromboembolic complications, and since LTX recipients lack the collateral bronchial circulation, pulmonary thromboembolism (PTE) may represent a pertinent yet largely under-diagnosed cause of post-transplantation respiratory failure. In the present systematic review, we sought to elucidate the occurrence and predilection site of PTE after LTX, and its potential impact on LTX-associated mortality...

Wei Zhang, John Fung
BACKGROUND: The use of calcineurin inhibitor (CNI)-based immunosuppressive regimens following liver transplantation (LTx) has improved the outcomes of the recipients. However, CNI has nephrotoxicity and causes short- and long-term renal complications. The progressive structural changes can be irreversible in the long-term, leading to chronic kidney dysfunction. The present review was to evaluate the different strategies of CNI application to renal function in liver recipients. DATA SOURCES: PubMed database was searched for relevant articles in English on the issue of immunosuppressive regimen and kidney injury that related to early minimization of CNI after LTx...

BACKGROUND: Lung transplantation (LTx) is frequently considered for patients with cystic fibrosis (CF) when FEV1 reaches <30%. This study estimated transplant-free survival for CF patients and FEV1 <30% and identified predictors of death without LTx. METHODS: We conducted a retrospective cohort study using the CF Foundation Patient Registry, 1/1/2003-12/31/2013. Adult patients (≥18 years) with FEV1 <30% prior to LTx were included. We performed Kaplan-Meier survival estimates censored at LTx...

BACKGROUND: The prognosis of patients after liver transplantation (LTx) with high Model of End-Stage Liver Disease (MELD) score (>30) is predicted, but patients with lower MELD scores (<30) have no conclusive studies of pre- and post-transplant risk factors that influence the long-term outcome. METHODS: This retrospective study reviewed 268 recipients with MELD score <30, from 2008 to 2013 in our institution, for evaluation of pre-transplant risk factors including patients' clinical background data, pre-transplant lymphocyte subpopulation, and early post-transplant infection complication as predictors for long-term survival after LTx...

BACKGROUND: Prior studies reveal that a significant proportion of patients with cystic fibrosis (CF) and advanced lung disease are not referred for lung transplant (LTx) evaluation. We sought to assess expert CF physician perspectives on the timing of LTx referral and investigate their LTx knowledge. METHODS: We developed an online anonymous survey that was distributed by the Cystic Fibrosis Foundation (CFF) to the medical directors of all CFF-accredited care centers in the United States in 2015...

A new bimodal fluorescent cationic calix[4]arene (L1) conjugate has been synthesized in multiple steps and well characterized by NMR and electrospray ionization-mass spectrometry (ESI-MS) techniques. L1 has been investigated for its DNA binding ability by various spectroscopy techniques like absorption, fluorescence, and circular dichroism (CD). The formation of L1-DNA complex has been confirmed by the gel electrophoresis in the presence of incremental concentration of L1. To visualize the packing of the plasmid (pBR322), detailed tapping mode atomic force microscopy study has been performed, which revealed blob-like structure of plasmid upon addition of the incremental amount of L1...

Solid organs may differ in their potential to induce and maintain a state of donor-specific tolerance. Previously, we induced stable immunological tolerance in a lung transplantation model in miniature swine. Here, we wished to transfer this established protocol into a heart transplantation model in miniature swine. Heterotopic heart transplantation (HTX) was performed in four and left-sided lung transplantation (LTX) in seven minipigs from gender- and SLA-mismatched donors. All recipients received nonmyeloablative irradiation, donor splenocyte infusion and intravenous pharmacologic immunosuppression for 28 postoperative days...

PURPOSE OF REVIEW: To provide latest information on differences between standard tacrolimus (TAC BID) and slow-released formulation of tacrolimus (Advagraf) in liver transplantation (LTx), and to discuss the latter's therapeutic value as a distinct entity. RECENT FINDINGS: Two articles on de-novo studies, several on conversion and one on survival analysis from the European Liver Transplant Registry published recently showed that low-dose Advagraf immediately after transplantation provided same protection to the kidney as standard dose delayed until day 5, and was associated with lower rejection rate; to maintain the same trough level after late conversion to Advagraf, an approximately 1...

OBJECTIVES: Cannabis is the most commonly abused illicit drug and the smokers are at the risk of lung infections, bullous emphysema and lung cancer. However, no evidence about the outcomes of lung transplantation (LTx) utilizing the lungs from such donors is available in the literature. METHODS: We retrospectively analysed lung 'organ offers' and LTx at our centre between January 2007 and November 2013. The outcomes of LTx utilizing lungs from donors with a history of cannabis smoking were compared with the outcomes of those with no such history using unadjusted model as well as propensity score matching...

Background: The criterion of Milan (CM) has been used as standard for indication of liver transplantation (LTx) for hepatocellular carcinoma (HCC) worldwide for nearly 20 years. Several centers have adopted criteria expanded in order to increase the number of patients eligible to liver transplantation, while maintaining good survival rates. In Brazil, since 2006, the criterion of Milan/Brazil (CMB), which disregards nodules <2 cm, is adopted, including patients with a higher number of small nodules...
