Background: Strongyloides spp hyperinfections are a worldwide phenomenon that proves fatal for solid organ transplant recipients. Screening protocols to guide prophylaxis management vary institution to institution from universal to epidemiology driven. Our institution initiated a universal screening protocol regardless of travel history and exposure to ensure no cases were missed., Methods: In this study, we describe the outcomes of three Strongyloides sero-positive children whom underwent intestinal or liver transplantation and the experience of universal screening at a tertiary care county hospital in South Florida., Results: Among the 66 intestine and liver pediatric transplant recipients who were screened for Strongyloides antibodies, only three were identified to be sero-positive via the screening mechanism. Two of three had significant epidemiology risk factors. None of the patients reviewed were found to have developed hyperinfection. However, reflecting on the experience represented by our series of pediatric patients, the risk of any complication related to Strongyloides status appears low. Even among this South Florida population whom come from or travel to endemic regions are in contact with sero-positive individuals, very few illustrate sero-positivity., Conclusion: While institutions continue to analyze the cost-benefit of universal testing vs. universal prophylaxis vs. targeted screening, the decision must encompass the patient population, rolling cumulative incidence, and morbidity and mortality related to this disease., (© 2021 Wiley Periodicals LLC.)

CMV disease continues to stand as a significant threat to the longevity of renal transplants in children. More pediatric recipients are CMV-negative with CMV-positive donor serologies resulting in a HR mismatch. The length of prophylaxis with GCV or VGCV required to optimally prevent recurrence of CMVDNAemia remains unknown. This study is a meta-analysis comparing GCV/VGCV prophylaxis regimens provided for <6 months, from 6 to <12 months, and ≥12 months after transplant in order to prevent CMVDNAemia. The search conducted involved PubMed, EMBASE, ISI Web of Science, and Cochrane Central Register from inception through December 2017. Search terms Kidney Transplantation, CMV, GCV, and VGCV provided 204 studies for abstract review. Studies excluded were those which did not itemize pediatric data separately, single case reports, and duplicate studies. Pooled analysis of five retrospective studies and one prospective study identified that there is no statistically significant difference in the incidence of CMV DNAemia when comparing <6 months of prophylaxis and >12 months of prophylaxis (23% and 15%, respectively, P = 0.23). Regardless of the length of prophylaxis, there was no statistical difference in the incidence of CMV DNAemia in the HR patients (6 to <12 months vs <6 months, P = 0.62; 6 to <12 months vs ≥12 months, P = 0.78; ≥12 months vs <6 months, P = 0.83). This study identifies no optimal length of prophylaxis for HR mismatch pediatric renal transplant patients as many develop CMV DNAemia., (© 2019 Wiley Periodicals, Inc.)

BIs are ubiquitous among the pediatric intestinal transplant patient population. Personalizing postoperative prophylaxis antibiotic regimens may improve outcomes in this population. A retrospective analysis of all pediatric patients who underwent intestinal transplantation was evaluated to compare standardized and tailored regimens of antibiotics provided as prophylaxis postoperatively. Patients in the standard group have both shorter time to and higher rate of BIs, which was statistically significant (P < 0.001). Of the children who developed a BI, there was no statistical difference in average times to the development of a second BI (293 vs 119 days, P = 0.211). The tailored group had prolonged times until the development of a MDRO (52.6 vs 63.9 days, P = 0.677). Although not statistically significant, the tailored group had a propensity to present with gram-negative pathogens after transplant as compared to the standard regimen group, which presented with gram-positive pathogens (P = 0.103). Children with a history of an MDRO held a 7.3 (P < 0.01) times more likelihood of death within a year of transplant. A tailored prophylactic antibiotic regimen in the post-transplant period appears to prolong the time to the first BI. Although the data do not show differences in mortality, further study may prove the impact of a tailored antibiotic regimen on morbidity and mortality rates., (© 2018 Wiley Periodicals, Inc.)
