Background: Although short-term renal allograft survival in children has improved over the years, long-term graft outcomes remain unclear. In this study we report the characteristics and other variables that impact long-term kidney graft survival in children.
Material And Methods: Records of 61 pediatric kidney transplant recipients (mean age: 14±3 years) performed at our institution between 1995 and 2011 were evaluated. Patients were divided into 2 groups (functional and non-functional grafts) to investigate the factors that impact graft survival. The groups were compared in terms of recipient characteristics, underlying disease, HLA status, immunosuppressive therapy, donor characteristics, acute rejection, and delayed graft function (DGF). Statistical significance was detected with the t and chi-squared tests (Pearson and Fisher's exact tests). Kaplan-Meier analysis was performed for graft survival.
Results: Overall graft survival at 1, 5, 10, and 15 years were 93%, 66%, 46%, and 41%, respectively. The median graft survival was 128.4 months (range: 3-188 months). Donor age, acute rejection, and DGF strongly predicted the chance of graft survival (p<0.05).
Conclusions: It appears that several modifiable risk factors can partially account for poorer graft survival in pediatric kidney transplant recipients.

Background: Maintenance immunosuppression is required for suppression of alloimmunity or allograft rejection. However, continuous use of immunosuppressants may lead to various side effects, necessitating the use of alternative immunosuppressive drugs. The early secreted antigenic target of 6 kDa (ESAT-6) is a virulence factor and immunoregulatory protein of mycobacterium tuberculosis (Mtb), which alters host immunity through dually regulating development or activation of various immune cells.

Multiple Aneurysmal Arterial Disease (MAD) is an extremely rare arterial vascular condition and is produced by an abnormal alteration of smooth muscle cells and neutrophils, producing a multiple-aneurysmal degeneration. We present the case of a 36-year-old patient with a MAD in the cerebral territory and extremities with no surgical indication; however, with an aneurysm of the right inferior renal segmental artery, inferior mesenteric artery, left common iliac artery, and right internal iliac artery with surgical indication. An open approach with single-stage surgical repair, including graft interposition, bypass, exclusion, and vascular reimplantation, was performed.

Antibody-mediated rejection (ABMR) remains a leading cause of graft loss during kidney transplantation. Ischemia reperfusion injury (IRI) has been reported to promote T-cell proliferation, leading to B-cell activation and subsequent production of donor-specific antibodies (DSA), which target antigens on the vascular endothelium. We hypothesize that a novel therapeutic strategy targeting highly toxic reactive oxygen species could mitigate oxidative stress and immune responses associated with IRI.

Bariatric surgery has been shown to be safe in chronic kidney disease and improves access of patients to transplantation. Whether bariatric surgery after kidney transplantation associates with improved graft or patient survival has not been examined nationally. We included adults with obesity who received a first kidney transplant according to the US Renal Data System between 2003-2019.

Introduction: Recurrent portal hypertension (PH) after liver transplant (LT) and its management are not well-studied. This study aims to evaluate the impact of transjugular intrahepatic portosystemic shunt (TIPS) on outcomes of recurrent PH.
Methods: From a cohort of 1846 LT recipients, 36 patients who underwent TIPS creation after LT were identified and considered as cases.
