13. Use of preoperative embolization prior to Transplant nephrectomy
ABSTRACT Introduction After a failed transplant, management of a non-functional graft with pain or recurrent infections can be challenging. Transplant nephrectomy (TN) can be a morbid procedure with the potential for significant blood loss. Embolization of the renal artery alone has been proposed as a method of reducing complications from an in vivo failed

14. Quantification of C4d deposition and hepatitis C virus RNA in tissue in cases of graft rejection and hepatitis C recurrence after liver transplantation
Histology is the gold standard for diagnosing acute rejection and hepatitis C recurrence after liver transplantation. However, differential diagnosis between the two can be difficult. We evaluated the role of C4d staining and quantification of hepatitis C virus (HCV) RNA levels in liver tissue. This was a retrospective study of 98 liver biopsy samples divide

15. An analysis of tacrolimus-related complications in the first 30 days after liver transplantation
OBJECTIVES: Orthotopic liver transplantation has improved survival in patients with end-stage liver disease; however, therapeutic strategies that achieve ideal immunosuppression and avoid early complications are lacking. To correlate the dose and level of Tacrolimus with early complications, e.g., rejection, infection and renal impairment, after liver trans

16. Human herpesvirus-6 and cytomegalovirus DNA in liver donor biopsies and their correlation with HLA matches and acute cellular rejection
Herpesvirus reactivation is common after liver transplantation. OBJECTIVE: Analyze the presence of cytomegalovirus (HCMV) and human herpesvirus-6 (HHV-6) DNA in liver donor biopsies, seeking to better understand issues involving human donor leukocyte antigens (HLA)-A, B and DR, as well as correlations with acute cellular rejection. METHODS: Fifty-nine liv

17. Frequency of alleles and haplotypes of the human leukocyte antigen system in Bauru, São Paulo, Brazil
Background: HLA allele identification is used in bone marrow transplant programs as HLA compatibility between the donor and recipient may prevent graft rejection. Objective: This study aimed to estimate the frequency of alleles and haplotypes of the HLA system in the region of Bauru and compare these with the frequencies found in other regions of the coun

18. Issues in solid-organ transplantation in children: translational research from bench to bedside
In this review, we identify important challenges facing physicians responsible for renal and cardiac transplantation in children based on a review of the contemporary medical literature. Regarding pediatric renal transplantation, we discuss the challenge of antibody-mediated rejection, focusing on both acute and chronic antibody-mediated rejection. We review

19. New immunosuppressive agents in pediatric transplantation
Immunosuppressive therapy in pediatrics continues to evolve. Over the past decade, newer immunosuppressive agents have been introduced into adult and pediatric transplant patients with the goal of improving patient and allograft survival. Unfortunately, large-scale randomized clinical trials are not commonly performed in children. The purpose of this review

20. Long-term outcomes of children after solid organ transplantation
Solid organ transplantation has transformed the lives of many children and adults by providing treatment for patients with organ failure who would have otherwise succumbed to their disease. The first successful transplant in 1954 was a kidney transplant between identical twins, which circumvented the problem of rejection from MHC incompatibility. Further pro

21. In vitro proliferation and differentiation of hepatic oval cells and their potential capacity for intrahepatic transplantation
Hepatic oval cells (HOCs) are recognized as facultative liver progenitor cells that play a role in liver regeneration after acute liver injury. Here, we investigated the in vitro proliferation and differentiation characteristics of HOCs in order to explore their potential capacity for intrahepatic transplantation. Clusters or scattered HOCs were detected in

22. Experimental diabetes exacerbates skin transplant rejection in rats
PURPOSE: To investigate the effect of chronic experimental diabetes on skin allografts in rats as a simple model that could clarify some basic aspects and mechanisms involved in transplant rejection in diabetes compared to normal animals. METHODS: Skin grafting was performed with fragments of tail skin from sex matched non diabetic Wistar rats engrafted onto

23. Transplante cardíaco: co-morbidades e complicações apresentadas por pacientes em um hospital universitário de Belo Horizonte
Cardiovascular diseases are a major cause of death in many developing countries including Brazil. The heart failure is a cardiovascular disease considered severe and irreversible. Nowadays, with advance in technology and medicine the last alternative of treatment to heart failure is the cardiac transplantation. To assist the patients submitted to the procedu

24. Advances in haploidentical stem cell transplantation
Hematopoietic stem cell transplantation from haploidentical donors is an attractive method of transplantation due to the immediate donor availability, ease of stem cell procurement and the possibility to collect additional donor cells for cellular therapy, if needed. Historically, maintaining T-cells in the graft has been associated with very high rates of g
