INTRODUCTION: Renal transplantation became a routine and successful medical treatment for Chronic Kidney Disease in the last 30 years all over the world. Introduction of Luminex based Single Antigen Beads (SAB) and recent BANFF consensus of histopathological phenotypes of different forms of rejection enables more precise diagnosis and changes the therapeutic approach. The graft biopsies, protocol or cause, indicated, remain a golden diagnostic tool for clinical follow up of kidney transplant recipients (KTR)...

REVIEW
Adriana Dejman, Marco A Ladino, David Roth
A substantial body of literature has unequivocally established that prevalent hepatitis C virus infection in chronic kidney disease (CKD), end stage renal disease (ESRD) and kidney transplant recipients is associated with a negative impact on patient survival. As a consequence of remarkable work that explained the details of the hepatitis C virus (HCV) genome, a class of drugs referred to as the direct-acting antiviral (DAA) agents were developed that targeted specific key sites in viral replication. Large clinical trials in the HCV-infected general population followed soon after that demonstrated cure rates exceeding 95%...

BACKGROUND: Cryptococcosis is an important opportunistic infection of organ transplant recipients. It is the third most common fungal infection of transplant patients and occurs especially in kidney recipients. Cryptococcus neoformans is a ubiquitous fungus which infects humans by inhalation of spores. C. gattii has more recently been recognised as a pathogen. Infection commonly is disseminated affecting mainly the central nervous system and the lungs. Cryptococcoma, a localised form of the disease, has been described in various organs...

Introduction: Encapsulating peritoneal sclerosis (EPS) is a clinical syndrome of progressive fibrotic change in response to prolonged, repetitive, and typically severe insult to the peritoneal mesothelium, often occurring in the setting of peritoneal dialysis (PD). Clear guidelines for successful management remain elusive. We describe the successful surgical management of EPS in a 28-year-old male s/p deceased donor kidney transplant for end-stage renal disease (ESRD) secondary to focal segmental glomerulosclerosis (FSGS)...

Background: Pre-transplant donor-specific anti-human leukocyte antigen antibodies (DSAs) are known risk factors for acute rejection and reduced graft survival after kidney transplantation. DSAs may also develop de novo DSAs (dnDSAs) after transplantation but the clinical implications of these antibodies remain uncertain. Methods: We undertook a systematic review of observational studies that examined the association between dnDSAs and graft and patient outcomes (through August 2017) with the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system of reporting used to assess the quality of evidence available...

BACKGROUND Gastrointestinal tract mucosal calcinosis (MC) tends to affect the gastric mucosa, while esophageal involvement is rare. Gastric MC may be seen with solid organ transplantation, use of aluminum-containing antacids or sucralfate, malignancy, and chronic renal failure. While the incidence of gastric MC in renal transplant patients undergoing gastric biopsy is common (between 15-29%), to our knowledge esophageal MC has only been previously reported 3 times. CASE REPORT A 68-year-old male dialysis-dependent end stage renal disease status-post deceased donor kidney transplant underwent an esophagogastroduodenoscopy (EGD) for dysphagia and diffuse esophageal wall thickening seen on imaging studies...

Safety, immunogenicity, pharmacokinetics, and efficacy of the IgG-degrading enzyme of Streptococcus pyogenes (IdeS [imlifidase]) were assessed in a single-center, open-label ascending-dose study in highly sensitized patients with chronic kidney disease. Eight patients with cytotoxic PRAs (median cytotoxic PRAs of 64%) at enrollment received 1 or 2 intravenous infusions of IdeS on consecutive days (0.12 mg/kg body weight ×2 [n = 3]; 0.25 mg/kg ×1 [n = 3], or 0.25 mg/kg ×2 [n = 2]). IgG degradation was observed in all subjects after IdeS treatment, with <1% plasma IgG remaining within 48 hours and remaining low up to 7 days...

Background: Enteric hyperoxaluria due to malabsorption may cause chronic oxalate nephropathy and lead to end-stage renal disease. Kidney transplantation is challenging given the risk of recurrent calcium-oxalate deposition and nephrolithiasis. Methods: We established a protocol to reduce plasma oxalic acid levels peritransplantation based on reduced intake and increased removal of oxalate. The outcomes of 10 kidney transplantation patients using this protocol are reported...

OBJECTIVES: Transplant vasculopathy is a significant predictor of poor outcome. We investigated whether age or pretransplant renal arterial vasculopathy of grafted kidneys affected allograft survival. MATERIALS AND METHODS: This study included 148 recipients and their donors. All donors underwent pretransplant renal arterial biopsy, with renal artery vascular score determined for each artery. Chronic rejection and graft loss were noted for all patients. RESULTS: Variable grades of pretransplant renal arterial lesions were noted in 103 donors (69...

In deceased donors, Ischemia/Reperfusion Injury (IRI) is an important cause of allograft dysfunction. Prolonged cold and warm ischemia time leads to a high risk of early post-transplant complications, including acute and chronic rejection. Ischemia not only up-regulates inflammatory cytokines and chemokines, but also enhances the expression of MHC-class II and adhesion molecules on epithelial and dendritic cells. Moreover, the Danger Associated Molecular Patterns (DAMPs) released from stressed or dying cells, not only cause or amplify tissue inflammation and trigger tissue repair in response to IRI, but also act as adjuvants that enhance DC maturation and potentiate the adaptive immune response...

Bardet-Biedl Syndrome (BBS) is a rare multi-systemic disease with autosomal recessive transmission. BBS was at first considered to be homogeneous as for its genetics, but subsequent studies have shown an extensive gene variability. Currently, 21 genes (BBS1-21) present on different chromosomes have been mapped: these genes are responsible for BBS phenotypes and they show a great heterogeneity of mutations.The most common genes are BBS1 (locus 11q13) and BBS10.We show here the case of a 50 year old patient with BBS...

Strongyloidiasis is caused by a soil-transmitted helminth that is endemic in tropical and subtropical countries. The parasite can complete its life cycle without leaving the host, allowing autoinfection and persistence. The risk of infection in travelers is low, but the disease may become lethal following immunosuppression. In case of solid organ transplantation, the risk of donor transmission has been suspected for several years. However, the management of live donors in this context has only recently been considered, and no guidelines exist for the management of deceased donors...

REVIEW

Improved understanding of sex and gender-specific differences in the aetiology, mechanisms and epidemiology of chronic kidney disease (CKD) could help nephrologists better address the needs of their patients. Population-based studies indicate that CKD epidemiology differs by sex, affecting more women than men, especially with regard to stage G3 CKD. The effects of longer life expectancy on the natural decline of glomerular filtration rate (GFR) with age, as well as potential overdiagnosis of CKD through the inappropriate use of GFR equations, might be in part responsible for the greater prevalence of CKD in women...

Post-transplant lymphoproliferative disorder (PTLD) is defined as a heterogeneous group of lymphoid and plasmocytic proliferations with variable malignant potential. They often arise in immunocompromised post solid organ transplant (SOT) patients linked with Epstein-Barr virus (EBV) infection. Clinical manifestations include fever, lymphadenopathy and organ involvement. Diagnosis of PTLD requires morphopathological tissue examination. Treatment of EBV-related PTLD in SOT patients includes immunosuppressive (IS) agents' reduction, use of antiviral medication, anti-B-lymphocyte antibodies and chemotherapy for high-risk patients...

We report the results of a study of survival, liver and kidney functions, and growth with a median follow-up of 24 years following liver transplantation in childhood. From 1988 to 1993, 128 children underwent deceased donor liver transplantation (median age: 2.5 years). Twenty-year patient and graft survival rates were 79% and 64%, respectively. Raised serum aminotransferase and/or γ-glutamyl transferase activities were present in 42% of survivors after a single transplantation. Graft histology (35 patients) showed signs of chronic rejection in 11 and biliary obstruction in 5...
