RESUMEN

BACKGROUND: Highly active antiretroviral therapy has turned human immunodeficiency virus (HIV)-infected patients with end-stage renal disease into suitable candidates for renal transplantation. We present the Brazilian experience with kidney transplantation in HIV-infected recipients observed in a multicenter study. METHODS: HIV-infected kidney transplant recipients and matched controls were evaluated for the incidence of delayed graft function (DGF), acute rejection (AR), infections, graft function, and survival of patients and renal grafts. RESULTS: Fifty-three HIV-infected recipients and 106 controls were enrolled. Baseline characteristics were similar, but a higher frequency of pre-transplant positivity for hepatitis C virus and cytomegalovirus infections was found in the HIV group. Immunosuppressive regimens did not differ, but a trend was observed toward lower use of anti-thymocyte globulin in the group of HIV-infected recipients (P = 0.079). The HIV-positive recipient group presented a higher incidence of treated AR (P = 0.036) and DGF (P = 0.044). Chronic Kidney Disease Epidemiology Collaboration estimated that glomerular filtration rate was similar at 6 months (P = 0.374) and at 12 months (P = 0.957). The median number of infections per patient was higher in the HIV-infected group (P = 0.018). The 1-year patient survival (P < 0.001) and graft survival (P = 0.004) were lower, but acceptable, in the group of HIV-infected patients. CONCLUSIONS: In the Brazilian experience, despite somewhat inferior outcomes, kidney transplantation is an adequate therapy for selected HIV-infected recipients.

RESUMEN

BACKGROUND: Tuberculosis (TB) is a great challenge in kidney transplantation, and is often associated with high morbidity and mortality. The aim of this study was to evaluate the epidemiology, clinical manifestations, and impact of TB in kidney transplant (KT) recipients. METHODS: We performed a retrospective analysis of a cohort of adult KT recipients from 2000 to 2012, with follow-up until July 2014. RESULTS: Among the 1737 KT recipients evaluated, 60 developed TB: a 5% cumulative incidence, and an incidence rate of 589.4 cases/100,000 patient-years. Median time to diagnosis was 13.4 months, with 40% of the cases occurring in the first year. New-onset diabetes was significantly associated with post-transplant TB (P = 0.018). Pulmonary TB represented 78% of the cases, including disseminated disease. Two patients received latent TB treatment and developed active infection. TB was associated with a significant reduction in patient and graft survival (74% vs. 90.2% in 5 years for patient survival, P = 0.001; and 58.6% vs. 80.2% in 5 years for graft survival, P < 0.001). Death and graft loss occurred in the first 6 months after diagnosis in one-third of the patients, 38.8% of them with disseminated disease. Disseminated disease was significantly associated with mortality compared to local disease (41.8% vs. 9.7%, P = 0.035). CONCLUSION: TB continues to be a great challenge in KT, especially in developing countries, with significant impact on patient and graft survival.

RESUMEN

BACKGROUND: Organ transplantation in Brazil is increasing, but one of its current obstacles is the negative response of the population to organ donation. Therefore, to make the process viable, it is essential that people are educated in organ donation and transplantation. The purpose of this research was to evaluate the main doubts on this subject and to clarify these issues by educating the respondents on the basis of their questions. METHODS: Handout questionnaires about organ donation and transplantation were distributed in public schools. The public targets were parents, teachers, and students. The interviewers were trained medical students. RESULTS: In this pilot study with 293 subjects, 97% of respondents had already heard about organ donation; 81% said they would donate their organs, whereas 76% said they would donate the organs of family members and 78% said they believe in the existence of organ trafficking in Brazil. CONCLUSIONS: The high percentage of respondents believing in the existence of an organ trade highlights the urgency in clarifying this topic. To do so, the population must be educated about the ethics of the process of donation, emphasizing the fact that there is no organ trade in Brazil.

RESUMEN

BACKGROUND: Kidney transplantation prior to dialysis (pre-emptive kidney transplantation, PKT) has been controversial because of the paucity of clinical evidence to clarify the risks and benefits of PKT. Several authors have confirmed a significant advantage of PKT in the treatment of patients with end-stage renal disease (ESRD). The aim of this study was to examine the characteristics of patients who received PKT or non-pre-emptive kidney transplant (NPKT). METHODS: We used a cohort of 323 consecutive kidney-transplanted children (53% boys) from Hospital da Criança Santo Antonio, Porto Alegre, Brazil, who underwent transplantation between January 2000 and December 2010. RESULTS: The main causes of ESRD were congenital anomalies of the kidney and urinary tract (CAKUT) (39%) and glomerulopathies (27.5%). The 12-, 36-, 60-, and 90-months death-censored graft survival rates were 97%, 92%, 86%, and 76%, respectively, in the PKT group, and 87%, 79%, 72%, and 65% in the NPKT group (P < .05). CONCLUSIONS: The results of this study suggest that pre-emptive transplantation is beneficial (hazard ratio = 0.37; 95% confidence interval: 0.18-0.82). The main causes of graft loss (n = 67) were recurrence of primary disease (21%), chronic allograft injury (17%), and death with a functioning graft (16%). We recommend PKT as a better choice for transplantation whenever possible to minimize ESRD morbidity and provide better long-term patient and graft survival.

RESUMEN

INTRODUCTION: Today there is an insufficient number of donated organs in Brazil. This is particularly due to the general population's and health care professionals' lack of information. Therefore, with this project we intend to consolidate knowledge on organ donation to teach health care students of different areas so they are able to propagate such knowledge. MATERIALS AND METHODS: In 2006, at Universidade Federal de Ciências da Saúde de Porto Alegre, an "Organ donation and transplants" subject was created, with the aim to educate health care students. In the next years, it was split in two subjects, named "Introduction to transplants" and "Donation and transplants." By enrolling, students get theoretical classes and practical experience in out- and inpatient facilities and in surgical environments at the Santa Casa Hospital Complex. Furthermore, they can participate in campaigns at parks, stadiums, and health care fairs that take place at several schools in Porto Alegre. To finish the subjects, students present a conclusion report. RESULTS: Seven years after implementation of the subject, and with more than 400 students enrolled, several accomplishments can be highlighted. For example, the creation of the Organ Transplantation League, the implementation of a day to spread conception of the donation-transplant process (with the elaboration of a Web page on the subject), and the release of a book on the subject written by students and professors. DISCUSSION AND CONCLUSION: Health care professionals' education is a central point in donation and transplant process. This is because they become, inevitably, educators, and this brings a long-term consequence, consisting of enhanced logistics skills on brain-death diagnosis and further transfer of information to the population (hopefully reducing denial by families at the time of the donation). We conclude that this is a project to be followed by other medical schools so that, effectively, the number of donors increases and, consequently, the transplantation of organs and tissues as well.

RESUMEN

Planned conversion from tacrolimus to sirolimus was evaluated in de novo kidney transplant recipients. In this multicenter, randomized, open-label study, 297 patients were initially treated with tacrolimus, mycophenolate sodium and prednisone. Of the 283 patients reaching 3 months, 97 were converted to sirolimus (SRL), 107 were maintained on tacrolimus (TAC) and 79 were patients receiving TAC without criteria to undergo intervention at month 3 (TACex). The primary objective was to show superior estimated glomerular filtration rate (eGFR) in the SRL group at month 24. Of the 258 patients who completed 24 months, 91 (94%) were in the SRL group, 101 (94%) in the TAC group and 66 (84%) in the TACex group. In the intention-to-treat population there were no differences in eGFR (66.2 ± 25.3 vs. 70.7 ± 25.1, p = 0.817) or in the severity of chronic sclerosing lesions scores in 24-month protocol biopsies. Higher mean urinary protein-to-creatinine ratio (0.36 ± 0.69 vs. 0.15 ± 0.53, p = 0.03) and higher incidence of treated acute rejection between months 3-24 (13.4% vs. 4.7%, p = 0.047) were observed in SRL compared to TAC group. In this population planned conversion from TAC to SRL 3 months after kidney transplantation was not associated with improved renal function at 24 months.

RESUMEN

Small children are a challenging group in whom to perform KT. This retrospective study analyzed the results of 62 KTs in children weighing <15 kg, performed between 1998 and 2010, using extraperitoneal access and anastomosis of the renal vessels of donors to the aorta and IVC or iliac vessels of the recipients. Thirty-two (51.6%) grafts were LRDTs and 30 (48.4%) were DDRTs-28 of them pediatric. The mean age at KT was 3.7 ± 2.2 yr (1-12), and the mean weight was 12.3 ± 2.1 kg (5.6-14.9). Ten children weighed <10 kg, and five (8.1%) children presented previous thrombosis of the venous system. At one and five yr, patient survival was 93.2% and 84.2%, and graft survival was 85.2% and 72.7%. There were no differences between the rates for LRDT and DDRT. There were six vascular complications (four vascular thromboses, one laceration, and one renal artery stenosis) and two perirenal collections. Extraperitoneal access is a valid KT technique in children weighing <15 kg.

RESUMEN

Recipients of extended-criteria donor (ECD) kidneys have poorer long-term outcomes compared to standard-criteria donor kidney recipients. We report 3-year outcomes from a randomized, phase III study in recipients of de novo ECD kidneys (n = 543) assigned (1:1:1) to either a more intensive (MI) or less intensive (LI) belatacept regimen, or cyclosporine. Three hundred twenty-three patients completed treatment by year 3. Patient survival with a functioning graft was comparable between groups (80% in MI, 82% in LI, 80% in cyclosporine). Mean calculated GFR (cGFR) was 11 mL/min higher in belatacept-treated versus cyclosporine-treated patients (42.7 in MI, 42.2 in LI, 31.5 mL/min in cyclosporine). More cyclosporine-treated patients (44%) progressed to GFR <30 mL/min (chronic kidney disease [CKD] stage 4/5) than belatacept-treated patients (27-30%). Acute rejection rates were similar between groups. Posttransplant lymphoproliferative disorder (PTLD) occurrence was higher in belatacept-treated patients (two in MI, three in LI), most of which occurred during the first 18 months; four additional cases (3 in LI, 1 in cyclosporine) occurred after 3 years. Tuberculosis was reported in two MI, four LI and no cyclosporine patients. In conclusion, at 3 years after transplantation, immunosuppression with belatacept resulted in similar patient survival, graft survival and acute rejection, with better renal function compared with cyclosporine. As previously reported, PTLD and tuberculosis were the principal safety findings associated with belatacept in this study population.

RESUMEN

The clinical profile of belatacept in kidney transplant recipients was evaluated to determine if earlier results in the BENEFIT study were sustained at 3 years. BENEFIT is a randomized 3 year, phase III study in adults receiving a kidney transplant from a living or standard criteria deceased donor. Patients were randomized to a more (MI) or less intensive (LI) regimen of belatacept, or cyclosporine. 471/666 patients completed ≥3 years of therapy. A total of 92% (MI), 92% (LI), and 89% (cyclosporine) of patients survived with a functioning graft. The mean calculated GFR (cGFR) was ∼21 mL/min/1.73 m(2) higher in the belatacept groups versus cyclosporine at year 3. From month 3 to month 36, the mean cGFR increased in the belatacept groups by +1.0 mL/min/1.73 m(2) /year (MI) and +1.2 mL/min/1.73 m(2) /year (LI) versus a decline of -2.0 mL/min/1.73 m(2) /year (cyclosporine). One cyclosporine-treated patient experienced acute rejection between year 2 and year 3. There were no new safety signals and no new posttransplant lymphoproliferative disorder (PTLD) cases after month 18. Belatacept-treated patients maintained a high rate of patient and graft survival that was comparable to cyclosporine-treated patients, despite an early increased occurrence of acute rejection and PTLD.

RESUMEN

Recipients of extended criteria donor (ECD) kidneys are at increased risk for graft dysfunction/loss, and may benefit from immunosuppression that avoids calcineurin inhibitor (CNI) nephrotoxicity. Belatacept, a selective costimulation blocker, may preserve renal function and improve long-term outcomes versus CNIs. BENEFIT-EXT (Belatacept Evaluation of Nephroprotection and Efficacy as First-line Immunosuppression Trial-EXTended criteria donors) is a 3-year, Phase III study that assessed a more (MI) or less intensive (LI) regimen of belatacept versus cyclosporine in adult ECD kidney transplant recipients. The co-primary endpoints at 12 months were composite patient/graft survival and a composite renal impairment endpoint. Patient/graft survival with belatacept was similar to cyclosporine (86% MI, 89% LI, 85% cyclosporine) at 12 months. Fewer belatacept patients reached the composite renal impairment endpoint versus cyclosporine (71% MI, 77% LI, 85% cyclosporine; p = 0.002 MI vs. cyclosporine; p = 0.06 LI vs. cyclosporine). The mean measured glomerular filtration rate was 4-7 mL/min higher on belatacept versus cyclosporine (p = 0.008 MI vs. cyclosporine; p = 0.1039 LI vs. cyclosporine), and the overall cardiovascular/metabolic profile was better on belatacept versus cyclosporine. The incidence of acute rejection was similar across groups (18% MI; 18% LI; 14% cyclosporine). Overall rates of infection and malignancy were similar between groups; however, more cases of posttransplant lymphoproliferative disorder (PTLD) occurred in the CNS on belatacept. ECD kidney transplant recipients treated with belatacept-based immunosuppression achieved similar patient/graft survival, better renal function, had an increased incidence of PTLD, and exhibited improvement in the cardiovascular/metabolic risk profile versus cyclosporine-treated patients.

RESUMEN

INTRODUCTION: Posttransplant diabetes mellitus (PTDM) is considered to be a serious complication of kidney transplantation that may reduce patient and graft survival. The immunosuppressant tacrolimus (TAC) increases the risk of developing PTDM. PURPOSE: We sought to estimate the risk of PTDM among renal transplant recipients treated with TAC, to identify other risk factors for PTDM, and to describe its consequences. METHODS: We retrospectively analyzed 413 recipients of ages >or=18 years who were free of diabetes before kidney transplantation. They were treated with TAC, cyclosporine (CyA), or sirolimus (SIR) plus steroid therapy with a minimum follow-up posttransplant of 6 months. PTDM was diagnosed according to American Diabetes Association guidelines. RESULTS: The mean age was 42.3 years and 230 (55.7%) were male. The initial immunosuppression for 171 (41.4%) patients was TAC; 221 (53.5%), CyA; and 21 (5.1%), SIR. PTDM occurred in 85/413 (20.6%) of patients. The median time to PTDM development was 54 days posttransplant. The cumulative incidence of PTDM was 24.6% and 17.2% for TAC and CyA treatment groups, respectively. In the intention-to-treat analysis, the proportion of patients receiving TAC who developed PTDM was significantly higher than that of CyA (HR = 1.6 [1.01-2.42]; P = .04). The Kaplan-Meier method showed that 78.5% patients taking TAC were free of PTDM at 6 months compared with 88.8% taking CyA (P = .003). The other independent risk factors were body mass index (BMI; P < .0001); recipient age (P < .0001) and acute rejection episodes (AE; P = .01). Three-year actuarial graft survivals were 85.5% for PTDM patients compared with 93.3% for those without diabetes (P = .021); patient survivals, 88.9% and 96.7%, respectively (P = .017). CONCLUSION: The incidence of PTDM is associated with TAC use, recipient age, BMI, and ARE. Therefore, PTDM is an important risk factor for graft loss and mortality.

RESUMEN

AIMS: To evaluate pancreas graft function, use of insulin, cholesterol, triglyceride levels, prescription of lipid-lowering drugs, and immunosuppressive regimens among recipients of simultaneous pancreas-kidney transplants (SPKT), who had initial immunosuppression with tacrolimus, sirolimus, and corticosteroids. METHODS: From 2000 to 2007, we performed 73 SKPT, among which we conducted a retrospective data analysis on 51 medical records of patients who had been followed for at least 6 to 72 months. We excluded from the analysis eight recipients who died before 6 months: eight with early pancreas graft losses and six for continued follow-up in other centers. RESULTS: There were four pancreas graft losses after 6 months due in two diabetes mellitus recurrence, one posttuberculosis treatment, and one after use of nonsteroidal inflammatory medication. Mean plasma glucose levels ranged from 84 to 103 mg/dL, while glycosylated hemoglobin (HbA1) levels ranged from 5.7% to 6.2%. At 6, 12, 36, and 60 months, 80%, 91%, 86%, and 75% of recipients, respectively, had HbA1 lower than 6.5%. In the same period, 10%, 8%, 10%, and 11% of recipients became insulin-dependent. Mean cholesterol levels (mg/dL) at 6, 12, 36, and 60 month were 190, 180, 196 and 193, while triglyceride levels (mg/dL) were 162, 129, 106, and 113 respectively. Recipient's rate of lipid-lowering drug use was 18%, 21%, 20%, and 22% at 6, 12, 36, and 60 months. Mean serum creatinine levels (mg/dL) with standard deviations were 1.3 +/- 0.4, 1.5 +/- 0.4, 1.6 +/- 0.5, 1.8 +/- 0.9, at 6, 12, 36 and 60 months respectively. Nineteen recipients had sirolimus suspended and 14 recipients, tacrolimus suspended as well for various reasons. CONCLUSION: Mean plasma glucose levels were normal during the period. About 10% of recipients became insulin-dependent and 20% required lipid-lowering drugs. The immunosuppressive regimen protocol had to be changed in 60% of patients.

RESUMEN

BACKGROUND: The increasing use of living kidney donors requires knowledge about long-term effects, especially number and causes of donors with chronic renal failure (CRF), and discussion about a regular follow-up program for donors, policies giving priority to kidney donors on the waiting list for a kidney, and a national record of donors. METHODS: We performed a Retrospective analysis of 470 records of our kidney donors from the kidney transplantation unit between 1977 and 1997. RESULTS: Five out of the 470 donors developed CRF (1.1%), with a calculated incidence of 610 per million people a year. CONCLUSION: The data showed that the risk of a donor developing CRF may be higher than in the in general population. These results showed the necessity of creating an effective follow-up program for donors and a national record.

RESUMEN

A favorable attitude of health professionals to organ donation can positively influence the decision of families of potential donors. By increasing health professionals knowledge about donation and transplantation and qualifying them to disseminate information, education has produced a positive response to increase the insufficient number of donors. Educating students early in their careers may become crucial in this setting. In order to supply the necessary information about the process of donation and transplantation, a medical school in association with the Hospital Transplant Coordination Department created an educational program of organ donation and transplantation. This course is intended for medical, biomedical, and nutrition students. The objective of our program is to supply basic knowledge about organ donation and transplantation to students of medicine, nutrition, and biomedicine and to enhance their commitment to this process. Each semester, 50 to 90 students are enrolled in the course, which involves a total of 25 hours. Various aspects are approached such as brain death, donor management, political and legal aspects of donation, and skin, lung, bone marrow, heart, pancreas, liver, and kidney transplantation. Between March 2006 and June 2007, three courses were carried out and 200 students were trained. The students evaluated the course and rated it as excellent, concluding that it contributed to their education. Their attitude toward organ donation and transplantation was strongly positive at the end of the course. This project aims to educate and stimulate students in the process of organ donation and transplantation and should be implemented in other medical schools.

RESUMEN

Corticosteroids are a cornerstone of immunosuppressive therapy in renal transplantation despite their side effects and morbidity. Newer immunosuppressive agents may be more effective to allow corticosteroid sparing. An interim analysis of 60 completed out of 100 planned primary kidney transplant recipients is presented. All patients on tacrolimus (Prograf) and MMF (Cellcept) were randomized into two groups following a 1:1 distribution for early steroid reduction at posttransplant day 7 (G1; n = 31) versus to long-term maintenance steroids (G2; n = 29). Primary efficacy endpoints were composite endpoint of death, graft loss, or severe acute rejection at 6 and 12 months follow-up. Safety evaluation included severity and frequency of diabetes mellitus, hypertension, hyperlipidemia, leukopenia, infection, malignancy, and severe adverse events. Mean age was 39.1 years, with 45.0% males and 66.7% Caucasians. African-Americans were 25.8% in G1 and 27.6% in G2. One death occurred in each group, as well as one case of severe (Banff III) rejection in G1 (P = 1.00). The incidence of rejection episodes between groups was not significant, namely, 41.9% in G1 and 20.7% in G2 (P = .077). There were no differences between groups concerning mean, systolic and diastolic blood pressure, HbA1c, or creatinine at 12 months. This interim analysis showed no evidence of an increased risk of poorer performance among the early steroid reduction or safety differences in kidney transplant recipients versus a regular dosage steroid group of patients. Further analysis of the complete study data is underway.

RESUMEN

Recently in Latin America, there has been a strong influence of the "Spanish model" of organ procurement. In 2001, The "Punta Cana Group" was created by Latin American transplantation coordinators with the objective of registering and improving the system of donation and procurement. In many countries there is no universal financial support from the government for medical treatment, including dialysis and transplantation. In other countries there is complete financial support for all of the population, including immunosuppressive drugs. Practically all countries have transplantation laws that follow ethical concepts, such as brain death diagnosis criteria, forms of consent, criteria of allocation, and inhibition of commerce. The rate of potential donors notified in countries that perform transplantations with deceased donors varied from 6 to 47 per million population yearly (pmp/y); The rate of effective donors varied from 1 to 20 pmp. In 2004, the mean rate of effective donors in Latin America was 5.4 pmp. The family refusal rate for the donation of organs varied from 28% in Uruguay to 70% in Peru. In some countries, such as Puerto Rico, Uruguay, and Cuba, it was more than 15 pmp, whereas in others countries deceased donors were practically not used. The number of patients on the waiting list for solid organ transplants in 12 Latin American countries is 55,000. Although the donation rate has increased by 100% during the last 10 years, it is lower than that in Europe (15 pmm/y) or the United States (20 pmp/y).

RESUMEN

In Brazil from 1993 to 1997, the rate of deceased organ donors did not increase, remaining fixed around 3 donors per million population (pmp/y). In 1997, seeking to improve this situation, we introduced a policy seeking to improve the transplantation rates. Among the organizational measures, we created hospital transplantation coordinators based on the Spanish model. Because there was not enough qualified personnel in this area, 18 basic courses (12 to 24 hours) were performed in 9 states, with the purpose to train 1020 coordinators. Furthermore 20 advanced courses (40 hours) were introduced to train these coordinators in 16 of the 21 Brazilian states that perform transplantations in addition to the Federal District, resulting in 920 new coordinators. As a consequence, there was a mean annual increase of 20% in donations, namely 600 deceased donors in 1999 (3.8 pmp), 840 in 2001 (5.2 pmp), and 1232 in 2004 (7.3 pmp). The potential rate of donors notification attained 4981 (29 pmp) in 2004, about 50% of the estimate figures. However, this rate is far lower than that necessary. It is important to continue coordination of new training (4 yearly) and retraining courses for qualified coordinators using 2-day intensive courses (16 hours).

RESUMEN

Rio Grande do Sul is a state of 10 million inhabitants, with 800 patients on the transplantation waiting list (80 per million population [pmp]/y) with a mean waiting time of 2 years. Up to 2000, there were 11 to 15 cornea donors and 70 to 80 transplantations yearly. Seeking to increase the number of corneas available for transplantation and reduce the time on the waiting list, we initiated a project wherein the hospital transplantation coordinator trained the morgue staff to evaluate all deceased persons. If the person had no contraindication, the morgue staff called the coordinator to interview the family. Whenever donation was authorized, the coordinator communicated with the Cornea Bank to perform a removal. There was a major increase in the number of donations (220/y) with this project responsible for more than 70% of the cornea donors on cardiac arrest in the Rio Grande do Sul State. The mean time on the waiting list decreased to 14 months. This model was efficient, and must be implemented in other hospitals in the state, attempting to decrease both the list and the waiting time for a corneal transplant.

RESUMEN

INTRODUCTION: There are few reports in the literature analyzing brain death epidemiology in suicides, or the rate of donation and family authorization in such situations. OBJECTIVE: The objectives of this study were to analyze the frequency of suicide as a cause of brain death and to compare the donation rates among this population with other causes of brain death. PATIENTS AND METHODS: We reviewed records from 2627 potential donors between 1988 and 2004. RESULTS: Within that period, 101 (3.8%) cases of brain death were recorded as suicides. The mean age was significantly lower (P < .05) in cases of suicide than for other causes (26.2 + 11.1 vs 34.4 + 16.5 years); there was a male prevalence (76.2% vs 60.8%). As to suicides, the donation rate was significantly higher than in other situations (62.3% vs 43.8%). This was due to a lower rate of negative family responses (17.8% vs 32.1%). CONCLUSIONS: Suicide is a frequent cause of brain death (3.8%), mainly among young men. The donation rate in this group is higher than that due to other causes of death because of a lower negative response rate by the family. The explanation remains to be clarified for such a low refusal rate for organ donation by the relatives of potential donors due to suicide.
