Background: Improvements in transplantation have increased the survival of children after kidney transplantation. These patients have complex needs, and the current medical system is not prepared to effectively transfer the care of these individuals from pediatric to adult health-care systems. Too often, transfer occurs during moments of crisis and is associated with poor outcomes. Objective: The aim of this study was to use a national database, the Scientific Registry of Transplant Recipients, to test the hypothesis that the increased risk of graft loss after transfer of care (from pediatric to adult services) for young adult kidney transplant recipients over a 2- to 3-year posttransfer follow-up period was related to these posttransfer risk factors (medication noncompliance, acute rejection, insurance status). Design: A retrospective, longitudinal, correlational design using secondary data was used to evaluate the transfer of care of 250 kidney transplant recipients (ages 16-25). Results: Seventy-seven (30.8%) individuals lost their graft within 3 years after transfer of care. Medication noncompliance, acute rejection, and serum creatinine >2.0 mg/dL at transfer were significant predictors of graft loss after accounting for multiple other factors. Conclusion: These individuals are at risk for graft loss after transfer of care and may benefit from increased personalized care during this risky period.

Background: Invasive fungal disease (IFD) is common in solid organ transplant (SOT) recipients and contributes to high morbidity and mortality. Although kidney transplantation (KT) is a commonly performed SOT, data on the risk factors for IFD-related mortality are limited. Methods: A 1:2 retrospective case-control study was performed in an experienced single center in the Republic of Korea. We reviewed the electronic medical records of patients with IFD after KT between February 1995 and March 2015. Results: Of 1963 kidney transplant recipients, 48 (2.5%) were diagnosed with IFD. The median interval from KT to IFD diagnosis was 172 days. Invasive aspergillosis (IA) was the most common, followed by invasive candidiasis (IC). Diabetes mellitus (DM) (odds ratio (OR) 3.72, 95% confidence interval (CI) 1.34–10.31, p = 0.011) and acute rejection (OR 3.41, 95% CI 1.41–8.21, p = 0.006) were associated with IFD development. In the subgroup analyses, concomitant bacterial infection was associated with IC development (OR 20.10, 95% CI 3.60–112.08, p = 0.001), and delayed graft function was associated with IA occurrence (OR 10.60, 95% CI 1.05–106.84, p = 0.045). The 12-week mortality rate in all patients was 50.0%. Mortality rates were significantly higher in older patients (adjusted hazard ratio (aHR) 1.06, 95% CI 1.02–1.11, p = 0.004), or those with DM (aHR 2.61, 95% CI 1.02–6.68, p = 0.044), deceased donor transplantation (aHR 2.68, 95% CI 1.03–6.95, p = 0.043), lymphocyte-depleting antibody usage (aHR 0.26, 95% CI 0.08–0.80, p = 0.019), acute rejection (aHR 0.38, 95% CI 0.15–0.97, p = 0.044), and concomitant bacterial infection (aHR 8.76, 95% CI 1.62–47.51, p = 0.012). Conclusions: A total of 50% of IFD cases occurred six months or later after transplantation. The IFD-related mortality rate was high in kidney transplant recipients despite the low incidence. DM and acute rejection were associated with high mortality, as well as IFD development. As old age, deceased donor transplantation, lymphocyte-depleting antibody usage, and concomitant bacterial infection are risk factors for IFD-related mortality, efforts for its early diagnosis and appropriate treatment are required.

ABSTRACT Objectives: to assess the prevalence of colonization and infection by multidrug-resistant bacteria in patients undergoing kidney transplantation and identify the rate of infection, morbidity and mortality and associated risk factors. Methods: a prospective cohort of 200 randomly included kidney transplant recipients. Epidemiological surveillance of the studied microorganisms was carried out in the first 24 hours and 7 days after transplantation. Results: ninety (45%) patients were considered colonized. Female sex, hypertension and diabetes (p<0.005), dialysis time (p<0.004), length of stay after transplantation, delayed renal function, and length of stay were identified as risk factors. The microorganisms were isolated from surgical site, bloodstream and urinary tract infections. Conclusions: colonization by resistant microorganisms in kidney transplant patients was frequent and risk factors associated with infection were identified. The results should guide the care team in order to minimize morbidity and mortality related to infectious causes in this population.

SummaryWe analysed whether the factor V Leiden mutation – the most common hereditary predisposing factor for venous thrombosis – is associated with early and long-term graft dysfunction after kidney transplantation in 394 Caucasian kidney transplant recipients. The presence of factor V Leiden mutation was identified by allele specific PCR. The prevalence of the factor V Leiden mutation was compared to 32216 unselected neonates. The prevalence of the factor V Leiden mutation (GA genotype) was similar in 394 kidney transplant recipients and 32216 neonates. The frequency of known factors predicting long-term graft function were similar in patients with the GA genotype and with the normal factor V gene (GG genotype). The GA genotype was associated with the occurrence of no primary graft function (risk: 2.87; 95% confidence interval: 1.01-8.26; p < 0.05), the number of dialysis after transplantation in patients with no primary graft function until graft function (7.5 ± 2.06 dialysis in GA patients; 4.2 ± 0.36 dialyses in GG patients; p < 0.05), and the risk for at least one acute rejection episode (risk: 3.83; 95% confidence interval: 1.38-10.59; p < 0.02). The slope of 1/creatinine per year was significantly lower in patients with the GA genotype (GA patients: – 0.0204 ± 0.008 dl/mg per year; GG patients: 0.0104 ± 0.004 dl/mg per year; p < 0.02). The annual enhancement of the daily protein excretion rate was elevated in patients with the GA genotype (GA patients: 38.5 ± 16.6 mg/24 h per year; GG patients: 4.9 ± 4.4 mg/24 h per year; p < 0.02). Our study showed that the factor V Leiden mutation is associated with the occurrence of delayed graft function, acute rejection episodes and chronic graft dysfunction after kidney transplantation.
