There is no evidence of whether everolimus (EVR) reduces cytomegalovirus (CMV) events in patients receiving steroid-free regimens. Besides, studies evaluating a tacrolimus (TAC) and EVR regimen are limited to 1-year follow-up. In this single-center prospective randomized trial, the incidence of CMV and 3-year efficacy and safety outcomes of EVR were compared to those of mycophenolate sodium (MPS) in a steroid-free regimen based on low-exposure TAC. Both groups received rabbit anti-thymocyte globulin (r-ATG) induction (6 mg/kg) and the steroids were withdrawn at day 7. Maintenance immunosuppression consisted of TAC (4-7 ng/ml until month 3 and 2-4 ng/ml thereafter) plus EVR (3-8 ng/ml) in the EVR group (n = 59); and TAC (4-7 ng/ml during all follow-up) plus MPS (1440 mg) in the MPS group (n = 56). The EVR group presented with a lower incidence of CMV events (18.6% vs. 50%, P = 0.001). No differences were observed in biopsy-proven acute rejection (6.8% vs. 3.6%, P = 0.680),graft loss (0.0% vs. 1.8%, P = 0.487),death (6.8% vs. 1.8%, P = 0.365), or estimated glomerular filtration rate at 36 months (61.1 ± 25.4 vs. 66.3 ± 24 ml/min/1.73 m , P = 0.369). A higher proportion of patients discontinued MPS treatment (8.5% vs. 26.8%, P = 0.013) for safety issues. In conclusion, EVR was associated with lower rates of CMV events in patients induced with standard dose r-ATG and a maintenance steroid-free regimen based on TAC. This regimen effectively prevented acute rejection and demonstrated a more favorable safety profile. (ClinicalTrials.gov:NCT02084446).
Background:The kidney transplant is a foreign body in the patient's organism, thus constituting a procedure that triggers an intense inflammatory reaction. Objective: To assess the clinical characteristics of people undergoing kidney transplantation with immune sensitization. Methodology: A descriptive, documentary, and retrospective study with a quantitative approach to data treatment and analysis was carried out between June and August 2019. Results: The association between donor-specific antibodies (DSA) and graft dysfunction (p < 0.03) and pregnancy (p < 0.04) was statistically significant. The occurrence of complications was also associated with the length of hospital stay (p < 0.00) and serum creatinine levels in the first week after transplant (p < 0.006). Conclusion:The clinical characterization showed that most patients had graft dysfunction, DSA, and complications, meaning that transplanted patients require a critical and individualized follow-up.

Objetivo: Avaliar os desfechos do transplante renal (TxR) em receptores de rins pareados e analisar os fatores de risco para desfechos inferiores. Métodos: Estudo retrospectivo de centro único incluindo todos os TxR com doador falecido realizados em 2014 em que ambos os rins foram transplantados em receptores do nosso centro. Os pacientes foram divididos em receptores do rim direito ou esquerdo. Foram avaliados os seguintes desfechos: função tardia do enxerto (FTE) rejeição aguda, perda, óbito, taxa de filtração glomerular estimada (TFGe) e incidência do desfecho composto de perda, óbito ou TFG<50mL/min em dois anos. A análise de risco foi feita através de regressão logística binária. Resultados: Os doadores eram predominantemente jovens (29+14 anos), homens (71%), que faleceram por trauma craniano (70%). Apenas dois doadores (6%) eram de critério expandido. Os receptores foram similares quanto à demografia: homens (77 vs. 57%, p=0,126), jovens (35+20 vs. 37+17 anos, p=0,668), com doença renal crônica de etiologia indeterminada (31 vs. 40%, p=0,179), estando em média 31+37 meses em diálise (27+25 vs. 36+47 meses, p=0,311), 7% eram retransplantes (9 vs. 5%, p=0,309) e as médias de PRA de classe I e II foram 6 20% (9+23 vs. 10+19%, p=0,907) e 9+20% (9+25 vs. 5+15%, p=0,476), respectivamente. O tempo médio de isquemia fria foi de 25+9h (24+9 vs. 27+9h, p=0,269) e 66% (66 vs. 66%, p=1,000) foram perfundidos em máquina de perfusão pulsátil. Todos foram induzidos com globulina anti-timócito, 52% (54 vs. 49%, p=0,808) receberam tacrolimo e everolimo como regime imunossupressor inicial e 62% (69 vs. 54%, p=0,319) n o receberam corticoide. Não houve diferença entre os grupos quanto à incidência de FTE (20 vs. 32%, p=0,282), rejeição aguda (0 vs. 11%, p=0,054), perda (0 vs. 6%, p=0,493), óbito (6 vs. 6%, p=1,000), TFGe (71+28 vs. 72+37 mL/min, p=0,877) ou quanto à incidência do desfecho composto de perda, óbito ou TFGe<50mL/min em 2 anos (29 vs. 23%, p=0,785). Em análise multivariada, o único fator de risco para o desfecho composto foi FTE (OR 4,120, IC 95% 1,194-14,271, p=0,025). Conclusão: Nesta coorte de TxR com rins pareados, FTE foi o único fator de risco para desfechos inferiores.
