- W2912777063 abstract "CMV-IgM + ve associated biliary atresia (CMV-BA) is a distinct etiological subgroup characterized by older age at presentation and a greater degree of inflammation and hepatic fibrosis, leading to a worse outcome. We report our experience with adjuvant antiviral therapy after Kasai portoenterostomy (KPE).Single-center prospective database identification of CMV-IgM + ve associated BA managed between 2003 and 2017. Since 2011, IV ganciclovir (5 mg/kg b.d.) and/or oral valganciclovir (520 mg/m2 b.d.) were started in the early postoperative period in selected cases and continued until negativity of CMV DNA load [Anti-Viral Therapy (AVT) Group 1]. Clearance of jaundice was defined as achieving a total bilirubin ≤20 μmol/L in post-KPE period and tested with a Fisher test; native liver survival (NLS) and overall actuarial survival (OS) were compared with untreated BA CMV IgM + ve patients (Group 2) using a Log-Rank test. A P value of <0.05 was regarded as significant. Data are quoted as median (IQ range).During the 14-year period, 376 infants with histologically confirmed BA were treated; of those 38(10%) were CMV IgM + ve at presentation. One child was considered too late at presentation for KPE and underwent primary liver transplantation while another only started AVT one month after KPE. Both were excluded from survival analysis. Therefore 36 underwent KPE [AVT Group 1 (n = 8) and Control Group 2 (n = 28)]. Overall age at surgery was 67(53-77) days. There was no difference in age at surgery (P = 0.26); bilirubin (P = 0.12); or AST (P = 0.15) between Group 1 and Group 2. Viral load data were available in 16 with a trend towards higher counts in the AVT group 1 [4935 (2668-18,817) vs. 1296 (253-10,471) c/ml; P = 0.06]. Clearance of jaundice was higher in AVT Group 1 (75% vs 21%, P = 0.009). There was no difference in OS (P = 0.24) but NLS was improved in the AVT Group 1 (75% vs. 25% at 2 years; P = 0.04).Although this finding may be regarded as preliminary, adjuvant antiviral therapy appeared to improve outcome in infants with CMV IgM + ve BA.III." @default.
