Vutukuru S, Solanki S, Kanojia RP. Delphi Method Analysis and Consensus of Prevalent Distinctive Practices for Biliary Atresia Management after Kasai Portoenterostomy. J Indian Assoc Pediatr Surg 2024; 29:271-276. [PMID: 38912031 PMCID: PMC11192269 DOI: 10.4103/jiaps.jiaps_250_23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2023] [Revised: 01/29/2024] [Accepted: 02/05/2024] [Indexed: 06/25/2024] Open
Abstract
Background Extrahepatic biliary atresia (BA) is seen in infants, with an incidence of 1 in 15,000 live births. The presentation is progressive jaundice, dark-colored urine, and clay-colored stools. Kasai portoenterostomy (KPE) is the commonly performed surgical procedure in these patients. Postoperatively, phenobarbitone, ursodeoxycholic acid (UDCA), steroids, and other drugs are given to improve bile drainage and prevent inflammation and fibrosis. However, a definitive protocol regarding the need for different drugs, dosage, and duration varies across individual surgeons and centers. No universally accepted protocol exists for postoperative management after KPE. Aim The aim of this study was to know the prevailing postoperative management of BA by subject experts and use the Delphi process to know if the experts want to change their practice based on the results from the survey. Material and Methods A questionnaire was made after discussing with two experts in the field of BA. The questionnaire was mailed to 25 subject experts. The first survey data were analyzed and shared with all responders. In the second survey, change in the management based on the results from the first survey was assessed. Results The Delphi questionnaire was answered by 17 experts. Postoperatively, prophylactic antibiotics are prescribed for 6-12 weeks by around 40% and >12 weeks by 30% of respondents. Phenobarbitone is prescribed for <3 months by nearly 50%. UDCA is prescribed for <3 months, ≤6 months, and 6 months-1 year by 47.1%, 23.5%, and 23.5% responders, respectively. Nearly 50% prescribe steroids (mostly prednisolone), and among them, two-thirds prescribe it for 6-12 weeks. Approximately 60% give antiviral drugs to children who are cytomegalovirus immunoglobulin M positive. In our survey, 50% of experts perform 5-10 KPE per year, and 25% each perform 10-15 and >15 KPE per year. The second survey noted that a significant percentage of responders want to change their practice according to consensus. Conclusion From our Delphi survey, an overview of the postoperative management of BA could be made. However, multicentric studies are required for uniform protocol on the postoperative management of BA.

Takeda M, Tsukui T, Cazares J, Tsuboi K, Ochi T, Shibuya S, Koga H, Lane GJ, Yamataka A. Prednisolone administration monitored by postoperative stool color achieves high jaundice clearance after laparoscopic portoenterostomy for biliary atresia. Pediatr Surg Int 2023; 39:299. [PMID: 37985521 DOI: 10.1007/s00383-023-05580-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 10/22/2023] [Indexed: 11/22/2023]
Abstract
PURPOSE Stool color (SC) for monitoring prednisolone use in biliary atresia (BA) patients after laparoscopic portoenterostomy (LPE) was reviewed. METHODS Subjects were 47 post-LPE BA patients given a reducing dose course of intravenous prednisolone. The course started at 4 mg/kg/day and gradually reduced, ultimately reaching a final total dose (TD) of 31.5 mg/kg. Normal SC indicated a course could progress until finished and was repeated until jaundice clearance (JC) was achieved. Abnormal SC persisting for two consecutive courses was the absolute indication for redo or liver transplantation (LTx). RESULTS JC was achieved in 38/47 (80.9%) LPE cases and 4/6 redos to give an overall JC rate (JCR) of 42/47 (89.4%). Outcomes after one course (n = 5; JCR: 80.0%; median TD: 30.0 mg/kg, interquartile range [IQR: 26.0-31.5]), two courses (n = 10; JCR: 90.0%; median TD: 62.5 mg/kg [IQR: 60.8-66.0]), three courses (n = 13; JCR: 92.3%; median TD: 90.0 mg/kg [IQR: 86.0-90.0]), four courses (n = 10; JCR: 80.0%; median TD: 120.0 mg/kg [IQR: 116.7-123.3]), five courses (n = 7; JCR: 100%; median TD: 156.0 mg/kg [IQR: 154.3-157.5]), six courses (n = 1; JCR: 100%; TD: 189.0 mg/kg), ten courses (n = 1; JCR: 100%; TD: 308 mg/kg). CONCLUSION Indications for repeat prednisolone and timing of redo/LTx based on SC monitoring appeared effective based on high JCR and successful redo/LTx. LEVELS OF EVIDENCE III.

Single cell RNA-sequencing analysis reveals that N-acetylcysteine partially reverses hepatic immune dysfunction in biliary atresia. JHEP Rep 2023; 5:100908. [PMID: 37869073 PMCID: PMC10585304 DOI: 10.1016/j.jhepr.2023.100908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2023] [Revised: 07/12/2023] [Accepted: 08/22/2023] [Indexed: 10/24/2023] Open
Abstract
Background & Aims Our previous study indicated that CD177+ neutrophil activation has a vital role in the pathogenesis of biliary atresia (BA), which is partially ameliorated by N-acetylcysteine (NAC) treatment. Here, we evaluated the clinical efficacy of NAC treatment and profiled liver-resident immune cells via single cell RNA-sequencing (scRNA-seq) analysis to provide a comprehensive immune landscape of NAC-derived immune regulation. Methods A pilot clinical study was conducted to evaluate the potential effects of intravenous NAC treatment on infants with BA, and a 3-month follow-up was carried out to assess treatment efficacy. scRNA-seq analysis of liver CD45+ immune cells in the control (n = 4), BA (n = 6), and BA + NAC (n = 6) groups was performed and the effects on innate cells, including neutrophil and monocyte-macrophage subsets, and lymphoid cells were evaluated. Results Intravenous NAC treatment demonstrated beneficial efficacy for infants with BA by improving bilirubin metabolism and bile acid flow. Two hepatic neutrophil subsets of innate cells were identified by scRNA-seq analysis. NAC treatment suppressed oxidative phosphorylation and reactive oxygen species production in immature neutrophils, which were transcriptionally and functionally similar to CD177+ neutrophils. We also observed the suppression of hepatic monocyte-mediated inflammation, decreased levels of oxidative phosphorylation, and M1 polarisation in Kupffer-like macrophages by NAC. In lymphoid cells, enhancement of humoral immune responses and attenuation of cellular immune responses were observed after NAC treatment. Moreover, cell-cell interaction analysis showed that innate/adaptive proinflammatory responses were downregulated by NAC. Conclusions Our clinical and scRNA-seq data demonstrated that intravenous NAC treatment partially reversed liver immune dysfunction, alleviated the proinflammatory responses in BA by targeting innate cells, and exhibited beneficial clinical efficacy. Impact and implications BA is a serious liver disease that affects newborns and has no effective drug treatment. In this study, scRNA-seq showed that NAC treatment can partially reverse the immune dysfunction of neutrophil extracellular trap-releasing CD177+ neutrophils and Kupffer cells, and lower the inflammatory responses of other innate immune cells in BA. In consequence, intravenous NAC treatment improved the clinical outcomes of patients with BA in term of bilirubin metabolism.

Front Pharmacol 2022; 13:956093. [PMID: 36188593 PMCID: PMC9516003 DOI: 10.3389/fphar.2022.956093] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2022] [Accepted: 08/19/2022] [Indexed: 11/30/2022] Open
Abstract
Background: Postoperative adjuvant steroid therapy is regarded as the conventional treatment for patients with biliary atresia (BA) who have undergone Kasai portoenterostomy (KP). However, whether the steroid therapy can improve BA outcomes is controversial. This meta-analysis aimed to evaluate the effects of adjuvant steroid therapy on the surgical prognosis of BA. Methods: We searched related studies published in PubMed, Embase, Web of Science, Cochrane, and the Chinese National Knowledge Infrastructure database up to May 2022. Data on the effect of steroid use on the clinical prognosis of the patients, including the jaundice clearance rate (JCR), native liver survival rate (NLSR) at 6, 12, and 24 months after KP, and the incidence of cholangitis, were extracted. Subgroup analyses based on age at KP, administration method, initial dosage, and steroid type were conducted. Statistical analysis was conducted using Stata/SE 12.0. Results: Eleven articles (a total of 1,032 patients) were included in the present meta-analysis. The results demonstrated that postoperative adjuvant steroid therapy improved JCR at the 6/12/24-month follow-up (RR: 1.35, 95% CI: 1.18–1.55, p < 0.001; RR:1.49, 95% CI, 1.12–1.99, p = 0.006; RR: 1.41, 95% CI: 1.14–1.75, p = 0.002) and improved NLSR at the 24-month follow-up (RR: 1.31, 95% CI: 1.03–1.68, p = 0.028). However, steroids could not significantly improve NLSR at the 6/12-month follow-up (RR: 1.06; 95% CI: 0.98–1.15; p = 0.17; RR: 1.22; 95% CI: 0.97–1.54; p = 0.095), and might not decrease the incidence of postoperative cholangitis (RR: 0.78, 95% CI: 0.60–1.01, p = 0.058). Furthermore, subgroup analyses confirmed that three variables (age at KP, administration method, and initial dosage) could affect the efficacy of steroids in BA patients. Conclusion: Postoperative adjuvant steroid therapy can significantly improve bile flow. The superiority of steroid therapy was more remarkable in patients aged ≤70 days at KP than in those aged >70 days. Additionally, intravenous followed by oral steroid administration method and medium initial dosage seemed to have the more reliable efficiency on bile flow. And patients treated by steroid had better long-term (24-month) native liver survival, but there is no significant effect on short-term native liver survival and postoperative cholangitis. Further studies are warranted.

Abstract
Following Kasai hepatic portoenterostomy (HPE), most patients with biliary atresia will eventually require liver transplantation due to progressive cirrhosis and liver failure. Preventing liver transplantation, or even delaying eventual liver transplantation, is the key to improving long-term outcomes. This review first examines the commonly used adjuvant therapies in post-HPE biliary atresia and the strength of the evidence supporting these therapies. Next, it examines the evolving frontiers of management through a comprehensive evaluation of both recently completed and ongoing clinical trials in biliary atresia. Promising therapies used in other cholestatic liver diseases with potential benefit in biliary atresia are discussed. Improving post-HPE management is critical to prevent complications, delay liver transplantation, and ultimately improve the long-term survival of patients with biliary atresia.

The incidence of different forms of ileus following surgery for abdominal birth defects in infants: a systematic review with a meta-analysis method. Innov Surg Sci 2021; 6:127-150. [PMID: 35937853 PMCID: PMC9294340 DOI: 10.1515/iss-2020-0042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/07/2020] [Accepted: 04/06/2021] [Indexed: 11/15/2022] Open
Abstract
Abstract
Objectives
Ileus following surgery can arise in different forms namely as paralytic ileus, adhesive small bowel obstruction or as anastomotic stenosis. The incidences of these different forms of ileus are not well known after abdominal birth defect surgery in infants. Therefore, this review aims to estimate the incidence in general between abdominal birth defects.
Content
Studies reporting on paralytic ileus, adhesive small bowel obstruction or anastomotic stenosis were considered eligible. PubMed and Embase were searched and risk of bias was assessed. Primary outcome was the incidence of complications. A meta-analysis was performed to pool the reported incidences in total and per birth defect separately.
Summary
This study represents a total of 11,617 patients described in 152 studies of which 86 (56%) had a follow-up of at least half a year. Pooled proportions were calculated as follows; paralytic ileus: 0.07 (95%-CI, 0.05–0.11; I
2=71%, p≤0.01) ranging from 0.14 (95% CI: 0.08–0.23) in gastroschisis to 0.05 (95%-CI: 0.02–0.13) in omphalocele. Adhesive small bowel obstruction: 0.06 (95%-CI: 0.05–0.07; I
2=74%, p≤0.01) ranging from 0.11 (95% CI: 0.06–0.19) in malrotation to 0.03 (95% CI: 0.02–0.06) in anorectal malformations. Anastomotic stenosis after a month 0.04 (95%-CI: 0.03–0.06; I
2=59%, p=0.30) ranging from 0.08 (95% CI: 0.04–0.14) in gastroschisis to 0.02 (95% CI: 0.01–0.04) in duodenal obstruction. Anastomotic stenosis within a month 0.03 (95%-CI 0.01–0.10; I
2=81%, p=0.02) was reviewed without separate analysis per birth defect.
Outlook
This review is the first to aggregate the known literature in order approximate the incidence of different forms of ileus for different abdominal birth defects. We showed these complications are common and the distribution varies between birth defects. Knowing which birth defects are most at risk can aid clinicians in taking prompt action, such as nasogastric tube placement, when an ileus is suspected. Future research should focus on the identification of risk factors and preventative measures. The incidences provided by this review can be used in those studies as a starting point for sample size calculations.

Abstract
Background Biliary atresia in very low birth weight (VLBW) and extremely low birth weight (ELBW) infants is rarely reported, and the optimal timing of Kasai portoenterostomy (KPE) in these cases remains unclear. Case presentation We report a case of biliary atresia in a preterm female infant of 24 weeks of gestation who weighed 824 g. She underwent exploratory laparotomy and intraoperative cholangiography at 58 days of age (weight, 1336 g). Despite the diagnosis of biliary atresia with a type I cyst, we could only perform gallbladder drainage at that time due to the unstable intraoperative condition. While we waited for her body weight to increase, KPE was performed at 122 days of age (corrected age: 16 days), when the patient weighed 2296 g. Although she initially became jaundice-free, her liver function deteriorated due to cholangitis, and she developed decompensated cholestatic liver cirrhosis. Living donor liver transplantation was successfully performed at 117 days after KPE, and the postoperative course was uneventful. The timing of KPE is difficult to determine and a review of the relevant literature revealed that a poor prognosis in VLBW and ELBW infants with BA. Conclusions Early KPE and careful postoperative follow-up, including liver transplantation is important for the improvement of outcomes.

Abstract
PURPOSE High-dose postoperative steroid therapy after Kasai portoenterostomy is reported to improve jaundice clearance and a strong anti-inflammatory activity might prevent fibrous tissue formation which is often observed at the porta hepatis in revision surgery. We started steroid pulse therapy for the patients with cessation of decrease in jaundice and aimed to evaluate the efficacy in this study. METHODS The demographics and outcomes of patients who underwent laparoscopic Kasai portoenterostomy and received steroid pulse therapy within 2 months postoperatively between September 2014 and December 2018 were retrospectively reviewed; the therapy was determined successful when the serum total bilirubin level decreased to or below two-thirds of the pre-therapy level after 2 weeks. Patient data in the successful group were compared with those in the unsuccessful group. RESULTS Steroid pulse therapy was successful in seven of 16 patients (43.8%). The percentage of patients whose serum total bilirubin level decreased to normal was significantly higher in the successful group at 3 months (85.7% vs. 11.1%, P = 0.0028) and after all (100% vs. 33.3%, P = 0.011). CONCLUSIONS Steroid pulse therapy was effective for some patients. Unsuccessful cases may have little chances of jaundice clearance; revision Kasai portoenterostomy would be a good option.

Comparison of laparoscopic portoenterostomy and open portoenterostomy for the treatment of biliary atresia. Surg Endosc 2019; 33:3143-3152. [PMID: 31190228 DOI: 10.1007/s00464-019-06905-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 06/06/2019] [Indexed: 02/05/2023]
Abstract
BACKGROUND Although open portoenterostomy (OPE) is considered the standard treatment for biliary atresia (BA), laparoscopic portoenterostomy (LPE) is conducted and reported by many investigators. Data on the safety and efficacy of LPE remain controversial. The aim of this meta-analysis is to compare the safety and efficacy of LPE and OPE for the treatment of BA. METHODS Three electronic databases were searched: PubMed, Embase, and the Cochrane Library. The eligible studies were limited to those published in English. The following keywords were used: "biliary atresia," "laparoscopic portoenterostomy," "Kasai portoenterostomy," "open portoenterostomy," "surgery," and "treatment." RESULTS Nine studies, including 434 patients, were analyzed. The operative time of LPE was significantly longer than that of OPE (MD = 40.55 min, 95% CI 4.83-76.27 min, P = 0.03). There was no significant difference between the two groups in terms of the time of hospital stay, the volume of intraoperative blood loss, or the rates of cholangitis, early clearance of jaundice or two-year survival with the native liver. The subgroup analyses revealed that the rate of early clearance of jaundice in the LPE group was significantly higher than that in the OPE group in studies published after 2016 (95% CI 1.04-1.75; P = 0.02). CONCLUSIONS The present meta-analysis provides evidence that LPE is a feasible option for patients with BA. LPE should be revaluated by further studies and longer follow-up.

Abstract
PURPOSE The purpose of this study was to determine perioperative risk factors for need of liver transplantation following hepatoportoenterostomy. METHODS A retrospective review of patients undergoing hepatoportoenterostomy for biliary atresia at our institution from 1990 to 2016 was completed. RESULTS A total of 81 patients were identified with a median age of 51 days (IQR: 33-68) at hepatoportoenterostomy and a median follow-up time of 5.7 years (IQR: 1-11.6). Ten-year overall survival was 93% (95% CI: 84-97). Thirty-six patients (44%) ultimately required transplantation at a median time from hepatoportoenterostomy of 8.9 months (IQR: 5.2-19). The 10-year transplant-free survival was 36% (95%CI: 24-49). Steroid use (N=42) was not associated with improved 10-yr transplant-free survival (33% vs. 38%, p=0.690). Age at hepatoportoenterostomy was not significantly associated with the need for transplantation. Multivariable logistic regression analysis demonstrated that total bilirubin >2mg/dL (OR: 97, p<0.001) and albumin < 3.5g/dL (OR: 24, p=0.027) at 3 months after surgery were independent predictors of the need for transplantation, while adjusting for age, sex, prematurity, and steroid use. CONCLUSION Overall survival for children with biliary atresia is excellent, although most patients will ultimately require liver transplantation. Total bilirubin and albumin level at 3 months following hepatoportoenterostomy are predictive of the need for transplantation. Steroid use is not associated with improved outcomes.

Abstract
BACKGROUND Biliary atresia (BA) is a neonatal obstructive biliary tract disease in which the intrahepatic and extrahepatic bile ducts are obstructed and can lead to congenital biliary atresia of cholestatic cirrhosis and eventually liver failure. It has been confirmed that the Kasai portoenterostomy is an effective treatment for BA. But most patients still face complications, such as cholangitis and liver fibrosis. Yinchen Sini decoction (YCSND), a traditional herbal formula, is used as a treatment for BA after Kasai portoenterostomy. And it is supported that YCSND can improve jaundice and liver fibrosis through multiple targets and pathways. Based on the published literature, this study aims to evaluate the current situation in the treatment of BA in children with YCSND. METHODS The following databases will be searched until October 2018: PubMed, The Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure (CNKI), Chinese biomedical literature database (CBM), Wan Fang Database, Chinese Scientific Journals Database (VIP) and other sources such as Hand searching, Conference proceeding, International Clinical Trials Registry Platform and Chinese Clinical Trials Registry. All randomized controlled trials (RCTs) of YCSND or related formula as a treatment for postoperative patients of Kasai portoenterostomy for BA will be collected. Data extraction and risk of bias assessments will be carried out by 2 verifiers independently. The risk of bias will be evaluated through the Cochrane risk of bias tool. Review Manager software (RevMan V.5.3.0) and STATA 15 will be used for statistical analyses. RESULTS This study will provide a high-quality synthesis of current evidence of YCSND in treating children undergoing Kasai portoenterostomy for BA from several aspects. CONCLUSION The conclusion of the meta-analysis will offer evidence for deciding whether YCSND is an effective measure for children undergoing Kasai portoenterostomy for BA. ETHICS AND DISSEMINATION Not only will this systematic review be published in a peer-reviewed journal, but it will also be propagated electronically and in print. The review will bring patients benefit and provide practitioners reference in the fields of conventional medicine. PROSPERO REGISTRATION NUMBER PROSPERO CRD 42018111321.

Abstract
BACKGROUND Biliary atresia is a life-threatening disease characterised by progressive destruction of both intra- and extra-hepatic biliary ducts. The mainstay of treatment is Kasai portoenterostomy, as soon as the disease has been confirmed. Glucocorticosteroids are steroid hormones which act on the glucocorticoid receptor and have a range of metabolic and immunomodulatory effects. Glucocorticosteroids are used to improve the postoperative outcomes in infants who have undergone Kasai portoenterostomy. OBJECTIVES To assess the beneficial and harmful effects of glucocorticosteroid administration versus placebo or no intervention following Kasai portoenterostomy in infants with biliary atresia. SEARCH METHODS We searched the Cochrane Hepato-Biliary Group Controlled Trials Register, Cochrane Central Register of Controlled Trials (CENTRAL) in the Cochrane Library, MEDLINE Ovid, Embase Ovid, Science Citation Index Expanded (Web of Science), and online trial registries (last search: 20 December 2017) for randomised controlled trials. SELECTION CRITERIA We included randomised clinical trials which assessed glucocorticosteroids for infants who have undergone Kasai portoenterostomy. For harm, we also considered quasi-randomised studies, observational studies, and case-control studies that were identified amongst the search results. DATA COLLECTION AND ANALYSIS We used standard methodological procedures expected by Cochrane. We assessed the risk of bias for each trial according to prespecified domains. We analysed data using both random-effects and fixed-effect models. We performed the analyses using Review Manager 5.3 and Trial Sequental Analysis software. We considered a P value of 0.025 or less, two-tailed, as statistically significant. We planned to calculate risk ratios (RRs) for dichotomous outcomes, and the mean difference (MD) for continuous outcomes. For all association measures, we planned to use 95% confidence intervals (CIs) as well as Trial Sequential Analysis-adjusted CIs. We used Trial Sequential Analyisis to control the risks of random errors; however, we were often unable to implement this beyond calculating the required information size as there were few trials and data. We assessed the certainty of the evidence using GRADE. MAIN RESULTS We found two randomised controlled trials fulfilling the inclusion criteria of our review. The trials provided data for meta-analysis. We judged the two trials as trials at low risk of bias. The two trials randomised a total of 213 infants to glucocorticosteroids versus placebo. In our Trial Sequential Analysis, the required information size (that is, the meta-analytic sample size) was not reached for any outcome. Trials were funded by charities, public organisations, and received support from private sector companies, none of which seemed to have an interest in the outcome of the respective trials. The effect of glucocorticosteroids after Kasai portoenterostomy on all-cause mortality is uncertain; the confidence interval is consistent with appreciable benefit and harm (RR 1.00; 95% CI 0.14 to 6.90; low-certainty evidence). The results showed little or no difference in adverse effects between the use of glucocorticosteroids or placebo after Kasai portoenterostomy, however this analysis was based on a single trial and we have low certainty in the result (RR 1.02; 95% CI 0.87 to 1.20;). Available data suggest that the proportions of infants who do not clear their jaundice at six months is similar between the two groups (RR 0.89; 95% CI 0.67 to 1.17; low-certainty evidence). All-cause mortality or liver transplantation did not differ at two years between the two groups (RR 1.00; 95% CI 0.72 to 1.39; low-certainty evidence). There were no data regarding health-related quality of life.Our searches also yielded 19 observational studies, some of them containing limited information on harmful effects of glucocorticosteroid treatment. We presented the extracted information narratively. We identified one further ongoing trial with no currently available results. AUTHORS' CONCLUSIONS The two meta-analysed randomised clinical trials present insufficient evidence to determine the effects of using glucocorticosteroids versus placebo after Kasai portoenterostomy in infants with biliary atresia on any of the primary or secondary review outcomes. There is insufficient evidence to support glucocorticosteroid use in the postoperative management of infants with biliary atresia for long-term outcomes of all-cause mortality or liver transplantation. It is also unclear if glucocorticosteroids are able to reduce the numbers of infants who did not clear their jaundice by six months. Further randomised, placebo-controlled trials are required to be able to determine if glucocorticosteroids may be of benefit in the postoperative management of infants with biliary atresia treated with Kasai portoenterostomy. Such trials need to be conducted as multicentre trials.

Abstract
Given that the aetiology of biliary atresia (BA) is complex and that there is a multiplicity of possible pathogenic mechanisms then it is perhaps not surprising that the evidence for effect of a number of different agents is contradictory. Post-operative cholangitis for instance is common, bacterial in origin and various antibiotic regimens have been tested (although none in a randomized trial) but continuation beyond the early post-operative period does not appear to offer any greater protection. There is an inflammatory reaction in about 25-35% of cases of BA illustrated by abnormal expression of class II antigen and upregulation of ICAM, VCAM and E-selectin with an infiltrate of immune-activated T cells (predominantly CD4 + Th1 and Th17) and NK cells and a systemic surge in inflammatory cytokines (e.g. TNF-α, IL-2, IL-12). This has potential as a therapeutic target and is the main hypothesis behind the rationale use of steroids. The first report of steroids was published in 1985 by Karrer and Lilly as "blast" therapy to treat recalcitrant cholangitis, followed by a multiplicity of small-scale uncontrolled studies suggesting benefit. To date there has been one randomized placebo-controlled study with a low-dose (prednisolone 2 mg/kg/day) regimen (2007); one with a high-dose (IV prednisolone 4 mg/kg/day regimen) (2014); two prospective high-dose open-label studies (2013); a prospective comparison of low- and high-dose regimen and a large (380 infants) retrospective comparison. The most recent meta-analysis (2016) identified a significant difference in clearance of jaundice at 6 months (OR 1.59, 95% CI 1.03-2.45, P = 0.04), in patients treated with high-dose steroids, particularly if < 70 days at surgery. Ursodeoxycholic acid (UDCA) may increase choleresis or change the ratio of endogenous bile acids to a less hydrophobic and, therefore, less toxic millieu. UDCA may protect cholangiocyte membranes against damage and perhaps reduce the tendency to fibrogenesis. Biochemical benefit has been shown in a single crossover trial in older BA children who had cleared their jaundice. Other potential adjuvant therapies include immunoglobulin therapy, anti-viral agents and Chinese herbs although real evidence of benefit is lacking.

Abstract
The use of adjuvant steroids following Kasai porteoenterostomy (KPE) for biliary atresia is controversial. The aim of this study was twofold: a systematic review of published literature and an update of the clinical Kings College Hospital series to look for evidence of an effect of age on the outcome in a group of BA infants treated with high-dose steroids. This clinical study included infants treated between January 2006 and June 2014 who underwent KPE by day 70 of life and who received high-dose steroids (oral prednisolone starting 5 mg/kg/day). They were subdivided into cohorts according to age at which KPE was performed. The outcome measured was clearance of jaundice (<20 µmol/L) by 6 months and native liver survival. R × C χ(2) analysis and log-rank tests were used, respectively, and P ≤ 0.05 was regarded as significant. 104 infants were included with a median age at KPE of 45 (range 12-70) days. 71/104 (67 %) cleared their jaundice by 6 months of age. Age-cohort analysis showed a trend (P = 0.03) favouring early KPE (e.g. 100 % of 11 infants operated on <30 days clearing their jaundice compared to 66 % of those operated on between 61 and 70 days). There was a significant native liver survival benefit for those operated on <45 days (5 year NLS estimate 69 versus 46 %; P = 0.05). Clearance of jaundice is related to the age at KPE in infants who receive high-dose steroids. Native liver survival appears to be improved as a result of this. This is the first study to show tangible longer-term benefit from high-dose steroids in biliary atresia.

Abstract
PURPOSE OF REVIEW The purpose of this study is to review advances in both the pathogenesis and clinical management of biliary atresia. RECENT FINDINGS Immunologic studies have further characterized roles of helper T-cells, B-cells, and natural killer cells in the immune dysregulation following viral replication within and damage of biliary epithelium. Prominin-1-expressing portal fibroblasts may play an integral role in the biliary fibrosis associated with biliary atresia. A number of genetic polymorphisms have been characterized as leading to susceptibility for biliary atresia. Postoperative corticosteroid therapy is not associated with greater transplant-free survival. Newborn screening may improve outcomes of infants with biliary atresia and may also provide a long-term cost benefit. SUMMARY Although recent advances have enhanced our understanding of pathogenesis and clinical management, biliary atresia remains a significant challenge requiring further investigation.

Abstract
Biliary atresia (BA), a chronic progressive cholestatic disease of infants, is the leading cause for liver transplant in children, especially in patients under two years of age. BA can be successfully treated with the Kasai portoenterostomy; however most patients still require a liver transplant, with up to one half of BA children needing a transplant by age two. In the current pediatric end-stage liver disease system, children with BA face the risk of not receiving a liver in a safe and timely manner. In this review, we discuss a number of possible solutions to help these children. We focus on two general approaches: (1) preventing/delaying need for transplantation, by optimizing the success of the Kasai operation; and (2) expediting transplantation when needed, by performing techniques other than the standard deceased-donor, whole, ABO-matched organ transplant.

Abstract
Objective. Symptoms and laboratory data between acute cholangitis (AC) patients treated with and AC patients treated without immunosuppressive drugs (corticosteroids or methotrexate) were compared to identify factors that can be meaningful to the diagnosis of AC. Methods. The Wilcoxon signed-rank test was used for comparison of baseline variables between the patients with AC treated with immunosuppressive drugs and those without it. The chi-squared test was used in the analysis of the symptoms. Results. In total, 69 patients with AC were enrolled. Fifteen patients were treated with immunosuppressants due to rheumatoid arthritis or other collagen diseases. Jaundice was less frequent in the patients treated with immunosuppressive drugs (P = 0.0351). T-Bil level was marginally lower in the patients treated with immunosuppressants (P = 0.086). AST and ALT levels were lower in the patients treated with immunosuppressants (P = 0.0417 and 0.022, respectively). Conclusions. The frequency of jaundice and AST and ALT levels were lower in the patients treated with immunosuppressive drugs. It is recommended that care be taken to evaluate jaundice, AST level, and ALT level in the diagnosis of AC.
