Immunosuppression in kidney transplantation is still largely driven by center-specific protocols and adjusted according to the presence of graft dysfunction, drug toxicity or infection. Due to the current inability to titrate immunosuppression to the needs of every single patient, this approach is burdened by an increased risk of under or over-immunosuppression. To extend allograft survival, immunosuppression should be decided based on reliable biomarkers capable of quantifying the alloimmune response and/or noninvasively diagnosing acute rejection...

Acute antibody-mediated rejection (AMR) remains an important challenge in the field of kidney transplantation despite the advances in immunosuppressive strategies, and has been recognized as an important cause of allograft dysfunction and graft loss. The treatments of acute AMR are not standardized and poor evidence is currently available on the effectiveness of therapy regimens with combinations of drugs. Standard treatment for acute AMR is based on 3 cornerstones: removal of donor-specific antibodies (DSAs) from the bloodstream, reduction of DSAs synthesis, and inhibition of the interaction between DSAs and human leukocyte antigen antigens on donor's cells...

BACKGROUND Development of post-transplant diabetes mellitus after kidney transplant (PTDM) significantly increases kidney graft loss and mortality. Several risk factors for PTDM have been reported, including Hispanic ethnicity and the use of calcineurin inhibitors and corticosteroids. The incidence and impact of PTDM in the Hispanic kidney transplant population is unknown. MATERIAL AND METHODS We retrospectively reviewed the medical records of 155 Hispanic and 124 Caucasian patients, who were not diabetics and underwent kidney transplant between January 2006 and December 2011...

Endogenous danger signals, or damage-associated molecular patterns (DAMPs), are generated in response to cell stress and activate innate immunity to provide a pivotal mechanism by which an organism can respond to damaged self. Accumulating experimental and clinical data have established the importance of DAMPs, which signal through innate pattern recognition receptors (PRRs) or DAMP-specific receptors, in regulating the alloresponse to solid organ transplantation (SOT). Moreover, DAMPs may incite distinct downstream cellular responses that could specifically contribute to the development of allograft fibrosis and chronic graft dysfunction...

INTRODUCTION: Although there are therapeutic options for the treatment of oral mucosa defects, the need for functional, anatomical and aesthetically similar substitutes persists, as well as for solutions to reduce autologous grafts morbidity. OBJECTIVE: To determine clinical and histological compatibility of equivalent oral mucosa allografts generated through tissue engineering in non-consanguineous rats. MATERIALS AND METHODS: We used a sample of oral mucosa from Sprague Dawley rats to obtain a fibroblast culture and a keratinocytes and fibroblasts co-culture...

Despite advances in testing compatibility between donor and recipient, graft rejection remains a current concern. Single-nucleotide polymorphisms (SNPs) that codify altered enzymes of metabolism, drug transport, and the immune system may contribute to graft rejection in transplant patients. This study examined the association between SNPs present in genes of these processes and occurrence of graft rejection episodes in 246 kidney transplant patients, 35% of which were diagnosed with rejection. Genotype-gene expression associations were also assessed...

Human papillomavirus (HPV) 16 E7 (E7) protein expression in skin promotes epithelial hyperproliferation and transformation to malignancy. Grafts of murine skin expressing E7 protein as a transgene in keratinocytes are not rejected from immunocompetent recipients, whereas grafts expressing ovalbumin (OVA), with or without coexpression of E7 protein, are promptly rejected, demonstrating that E7-associated non-antigen-specific local immunosuppression is not a major determinant of lack of rejection of E7 transgenic skin...

REVIEW
Katayoun Behnam Sani, Birgit Sawitzki
Ever since its first application in clinical medicine, scientists have urged to induce tolerance towards foreign allogeneic transplants and thus avoid rejection by the recipient's immune system. This would circumvent chronic use of immunosuppressive drugs (IS) and thus avoid development of IS-induced side effects, which are contributing to the still unsatisfactory long-term graft and patient survival after solid organ transplantation. Although manifold strategies of tolerance induction have been described in preclinical models, only three therapeutic approaches have been successfully utilized in a still small number of patients...

In Asian countries, concomitant splenectomy in living donor liver transplantation (LDLT) is indicated to modulate the portal vein pressure in the small sized graft to protect against small for size syndrome. While concomitant splenectomy in deceased donor liver transplantation is almost contraindicated based on western reports of increased mortality and morbidity rate due to septic complications, there are few studies about that in LDLT. So, we retrospectively investigated the clinical outcome of adult LDLT at Kyoto University Hospital from July 2010 to July 2016...

Background: Kidney transplantation is associated with harmful processes affecting the viability of the graft. One of these processes is associated with the phenomenon of ischaemia-reperfusion injury. Anaesthetic conditioning is a widely described strategy to attenuate ischaemia-reperfusion injury. We therefore conducted the Volatile Anaesthetic Protection of Renal Transplants-1 trial, a pilot project evaluating the influence of two anaesthetic regimens, propofol- vs sevoflurane-based anaesthesia, on biochemical and clinical outcomes in living donor kidney transplantation...

In immunocompromised patients, the NoV infection is prolonged and severe. We retrospectively studied the severity of the NoV infection in children after an ITx, the treatment, and the long-term evolution. Norovirus PCR in stools was positive for 19 children in 21 separate episodes. The infection was symptomatic in 18 cases. At diagnosis, the median weight loss was 5% (0-11) and the creatinine clearance was 75 mL/min/1.73 m(2) (19-142). On 14 digestive biopsies, the pathological findings were non-specific with a constant mononuclear infiltration, showing signs of rejection in one case...

BACKGROUND: While screening for asymptomatic BK viremia (BKV) has been well studied in isolated kidney transplant recipients, there is a paucity of published outcomes in simultaneous pancreas-kidney (SPK) transplant recipients who underwent BKV screening followed by pre-emptive reduction of immunosuppression. METHODS: This is a single-center, retrospective review of 31 consecutive SPK recipients who were transplanted over a five year period following the initiation of a serum BKV screening protocol...

Pyelonephritis post-renal transplantation is common and in up to 50% of cases can be asymptomatic. Transplant pyelonephritis shares a lot of histopathological features with acute cellular rejection. We present a case of asymptomatic acute graft pyelonephritis where a renal biopsy was complicated by sepsis, and discuss the difficulties in interpretation of renal histology in the setting of transplant pyelonephritis where rejection may also be a possibility, but differentiation is challenging.

PURPOSE: Acute cellular rejection is the major cause of immune-mediated graft failure early in the course of kidney transplantation, whereas chronic antibody-mediated rejection is a major contributor to graft loss in the late post-transplant phase. Based mainly on the results of short-term studies, the calcineurin inhibitor tacrolimus prevails over the mammalian target of rapamycin (mTOR) inhibitors. However, the toxicity profile of the two drug categories differs, making the interchange between them appealing...

BACKGROUND: Fresh or frozen nonvascularized osteotendinous joint allografts (OTJA) have not been used previously, clinically or experimentally, for metacarpophalangeal joint reconstruction. Therefore, we evaluated the viability of OTJA for metatarsophalangeal joint (MTJ) reconstruction in rats. METHODS: In the experimental group of 12 Lewis rats, we reconstructed the MTJ of the third digit of the hindlimb with a fresh, nonvascularized OTJA obtained from the same digit from 12 donor rats...

Corneal transplantation (keratoplasty) is the most frequently performed form of transplantation worldwide. A rejection reaction against the transplant is the main complication occurring after transplantation in an already vascularized, so-called "high-risk" recipient eye. Our group has shown that clinically invisible lymphatic vessels play a crucial role in the induction of a rejection reaction against the corneal graft, and that anti-(lymph)angiogenic therapies in the mouse model of keratoplasty can significantly improve transplant survival...

PURPOSE OF REVIEW: Pediatric keratoplasty poses unique challenges in clinical and surgical management. However, successful transplantation can afford a child vision in an otherwise poorly seeing eye. This review will provide an update on recent advances in pediatric keratoplasty. RECENT FINDINGS: Although children who receive corneal transplants remain at increased risk of rejection, infection, and graft dehiscence compared with adult corneal transplant recipients, new surgical techniques, and advances in clinical management have led to better outcomes...
