AbstractDonor-derived cell-free DNA (dd-cfDNA) has been of major interest recently as a non-invasive marker of graft injury, but has not yet been extensively tested in children. From May to September in 2019, a total of 76 pediatric patients receiving a liver graft were enrolled and there were 27 patients excluded. Ultimately plasma samples and matched liver specimens from 49 patients were successfully collected whenever rejection was suspected clinically. Dd-cfDNA were analyzed and then compared to biopsy. Of these, 11 (22.4%) patients were found to have rejection by biopsy. Dd-cfDNA levels were higher among patients with rejection compared to those with no rejection. In subgroup analysis, dd-cfDNA% among patients with rejection differed from those with EBV/CMV infection and DILI patients. Similarly, observations were available concerning dd-cfDNA (cp/mL). The AUC for dd-cfDNA% and dd-cfDNA (cp/mL) were 0.878, 0.841, respectively, both of which were higher than conventional LFTs. For rejection, dd-cfDNA% ≥ 28.7% yielded a sensitivity of 72.7%, specificity 94.7% and dd-cfDNA (cp/mL) ≥ 2076 cp/mL, yielded a sensitivity of 81.8%, specificity 81.9%. Of note, the dd-cfDNA distribution was significantly different between whole liver and LLS transplantation. In the setting of pediatric LTx, dd-cfDNA appears to be a sensitive biomarker indicating the presence of rejection.International Clinical Trails Registry Platform: ChiCTR1900022406.

Liver transplantation is a life-saving procedure for many forms of end-stage liver disease in pediatrics. Cytomegalovirus (CMV) is the most common and signifi cant posttransplant infection after pediatric liver transplant (PLT) with developing an episode of CMV infection or disease. It is well known that CMV increases risk of graft loss. The review presents aspects of etiology and epidemiology of CMV after PLT, approaches employed in diagnostics and prophylaxis of CMV, algorithms for valganciclovir dosing and methods to prevent complications associated with CMV. The latest data on current prevention strategies in pediatric liver transplantation centers in the world are also presented.

ABSTRACT AIM: To study and compare the incidence and time of occurrence of cytomegalovirus (CMV) infection in the posttransplant period in adult and pediatric liver transplant recipients. MATERIALS AND METHODS: Consecutive live donor liver transplant recipients not on CMV prophylaxis, were prospectively enrolled from March 2012 to September 2015 and followed up for 1 year post transplant to look for CMV infection. For analysis, patients were divided into pediatric (up to 18 years) and adult (>18 years) age groups. RESULTS: The study population of 146 patients consisted of 132 adult and 14 pediatric patients. Overall CMV infection posttransplant was seen in 54/146 (36.98%) patients, and 16/54 (29.6%) patients developed CMV disease. Post-transplant CMV infection rate was significantly higher in pediatric patients(10/14 [71.4%]) as compared to adults (44/132 [33.4%]) (P = 0.004). Among adults, CMV infection was seen in 22 (50%) patients in the 1st month, 13 (29.5%) patients in the 2nd month, 5 (11.4%) patients in the 3rd month, 2 (4.5%) patients in the 4th month, and 1 (2.3%) patient each in the 5th and 6th month. However, in pediatric patients, all the patients having CMV infection had it in the 1st-month posttransplant (P = 0.003). The median time of occurrence of CMV infection was 11.5 (7.75–19.00) days in pediatric patients versus 30 (18.5–54.5) days in adult patients (P = 0.001). CONCLUSIONS: The results of this study show a clear difference in the incidence and timeline of posttransplant CMV infection in pediatric patients as compared to adults.
