Abstract
The clinical diagnosis of biliary atresia (BA) poses challenges, particularly in distinguishing it from cholestasis (CS). Moreover, the prognosis for BA is unfavorable and there is a dearth of effective non-invasive diagnostic models for detection. Therefore, the aim of this study is to elucidate the metabolic disparities among children with BA, CS, and normal controls (NC) without any hepatic abnormalities through comprehensive metabolomics analysis. Additionally, our objective is to develop an advanced diagnostic model that enables identification of BA. The plasma samples from 90 children with BA, 48 children with CS, and 47 NC without any liver abnormalities children were subjected to metabolomics analysis, revealing significant differences in metabolite profiles among the 3 groups, particularly between BA and CS. A total of 238 differential metabolites were identified in the positive mode, while 89 differential metabolites were detected in the negative mode. Enrichment analysis revealed 10 distinct metabolic pathways that differed, such as lysine degradation, bile acid biosynthesis. A total of 18 biomarkers were identified through biomarker analysis, and in combination with the exploration of 3 additional biomarkers (LysoPC(18:2(9Z,12Z)), PC (22:5(7Z,10Z,13Z,16Z,19Z)/14:0), and Biliverdin-IX-α), a diagnostic model for BA was constructed using logistic regression analysis. The resulting ROC area under the curve was determined to be 0.968. This study presents an innovative and pioneering approach that utilizes metabolomics analysis to develop a diagnostic model for BA, thereby reducing the need for unnecessary invasive examinations and contributing to advancements in diagnosis and prognosis for patients with BA.

Low-dose biliatresone treatment of pregnant mice causes subclinical biliary disease in their offspring: Evidence for a spectrum of neonatal injury. PLoS One 2024; 19:e0301824.

Abstract
Biliary atresia is a neonatal disease characterized by damage, inflammation, and fibrosis of the liver and bile ducts and by abnormal bile metabolism. It likely results from a prenatal environmental exposure that spares the mother and affects the fetus. Our aim was to develop a model of fetal injury by exposing pregnant mice to low-dose biliatresone, a plant toxin implicated in biliary atresia in livestock, and then to determine whether there was a hepatobiliary phenotype in their pups. Pregnant mice were treated orally with 15 mg/kg/d biliatresone for 2 days. Histology of the liver and bile ducts, serum bile acids, and liver immune cells of pups from treated mothers were analyzed at P5 and P21. Pups had no evidence of histological liver or bile duct injury or fibrosis at either timepoint. In addition, growth was normal. However, serum levels of glycocholic acid were elevated at P5, suggesting altered bile metabolism, and the serum bile acid profile became increasingly abnormal through P21, with enhanced glycine conjugation of bile acids. There was also immune cell activation observed in the liver at P21. These results suggest that prenatal exposure to low doses of an environmental toxin can cause subclinical disease including liver inflammation and aberrant bile metabolism even in the absence of histological changes. This finding suggests a wide potential spectrum of disease after fetal biliary injury.

Int J Mol Sci 2023; 24:14719. [PMID: 37834180 PMCID: PMC10572496 DOI: 10.3390/ijms241914719] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2023] [Revised: 09/22/2023] [Accepted: 09/26/2023] [Indexed: 10/15/2023] Open
Abstract
Nonsyndromic biliary atresia (BA) is a rare polygenic disease, with autoimmunity, virus infection and inflammation thought to play roles in its pathogenesis. We conducted a genome-wide association study in 336 nonsyndromic BA infants and 8900 controls. Our results validated the association of rs17095355 in ADD3 with BA risk (odds ratio (OR) = 1.70, 95% confidence interval (95% CI) = 1.49-1.99; p = 4.07 × 10-11). An eQTL analysis revealed that the risk allele of rs17095355 was associated with increased expression of ADD3. Single-cell RNA-sequencing data and immunofluorescence analysis revealed that ADD3 was moderately expressed in cholangiocytes and weakly expressed in hepatocytes. Immuno-fluorescent staining showed abnormal deposition of ADD3 in the cytoplasm of BA hepatocytes. No ADD3 auto-antibody was observed in the plasma of BA infants. In the HLA gene region, no variants achieved genome-wide significance. HLA-DQB1 residue Ala57 is the most significant residue in the MHC region (OR = 1.44, 95% CI = 1.20-1.74; p = 1.23 × 10-4), and HLA-DQB1 was aberrantly expressed in the bile duct cells. GWAS stratified by cytomegalovirus (CMV) IgM status in 87 CMV IgM (+) BA cases versus 141 CMV IgM (-) BA cases did not yield genome-wide significant associations. These findings support the notion that common variants of ADD3 account for BA risk. The HLA genes might have a minimal role in the genetic predisposition of BA due to the weak association signal. CMV IgM (+) BA patients might not have different genetic risk factor profiles compared to CMV IgM (-) subtype.

Abstract
PURPOSE Immunological abnormalities have been hypothesized as a pathogenesis of biliary atresia (BA). We previously investigated the frequency and function of circulating regulatory T-cells (Tregs) and reported no differences compared to controls. However, the local Treg profile remains uncertain. We aimed to investigate the frequency of Tregs in BA liver tissues. METHODS The number of lymphocytes, CD4+ cells, and CD4+FOXP3+ Tregs infiltrating the portal tract and the percentage of Tregs among CD4+ cells of BA and control patients were visually counted. The correlation between these data and clinical indicators was also examined. RESULTS The number of lymphocytes, CD4+ cells, and CD4+FOXP3+ Tregs was higher in the BA group. However, the percentage of Tregs among CD4+ cells was similar in both groups. Each parameter was correlated with serum γ-GTP, but there was no clear association with liver fibrosis, jaundice clearance, and native liver survival. CONCLUSION The number of Tregs infiltrating the portal tract was higher in BA patients. However, the infiltration of lymphocytes was also generally increased. Tregs appear to be unsuccessful in suppressing progressive inflammation in BA patients, despite recruitment to local sites. Investigation of Treg function in the local environment is warranted.

Abstract
Biliary atresia (BA) is a rare but devastating cholangiopathy. We report a case series of dysmorphic gallbladders detected during prenatal ultrasound, which were confirmed as BA after birth. We present the prenatal ultrasound findings as well as integral follow-up, with an aim to raise awareness regarding the association between BA and dysmorphic gallbladder. Although this dysmorphic gallbladder is a strong hint for BA, it is also important to search for other related sonographic features, such as the presence of microcysts at the hepatic hilum, dilated right hepatic artery, and seroperitoneum, which may provide more evidence for the diagnosis of BA.

Abstract
OBJECTIVE To evaluate the accuracy of intraoperative hepatic subcapsular spider-like telangiectasia (HSST) sign for differentiating biliary atresia (BA) from other causes of hepatic cholestasis. METHODS The data of 69 patients with jaundice treated from January 2019 to December 2021 were retrospectively analyzed. Based on intraoperative cholangiography (IOC), the patients were divided into two groups: the BA group (n = 49) and the non-BA group (n = 20). The biochemistry tests, liver ultrasound, liver stiffness value and HSST sign of the two groups were compared. RESULTS The incidence of abnormal gallbladder, elevated γ-glutamyl transpeptidase (γ-GGT) > 182.0U/L and abnormal liver stiffness (> 6.4 kPa) in BA group were significantly higher than those in non-BA group (P < 0.001). The HSST sign was present in all BA patients and not found in non-BA group. The area under receiver operating curve of direct bilirubin(DBIL), γ-GGT, abnormal gallbladder, liver stiffness value and HSST sign were 0.53, 0.84, 0.78, 0.96, and 1.00, respectively. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value(NPV) of HSST sign in the diagnosis of BA were all 100%. CONCLUSION Presence of HSST sign on diagnostic laparoscopy is highly suggestive of BA.It can be used in the differential diagnosis of BA and non-BA. LEVEL OF EVIDENCE Level III.

Abstract
PURPOSE Although the impairment of regulatory T-cells (Tregs) has been shown in the liver or portal area of biliary atresia (BA) the frequency and function of circulating Tregs in BA patients is poorly understood. We aimed to investigate the frequency and function of circulating Tregs in BA patients. METHODS Peripheral blood mononuclear cells were collected from 25 BA patients and 24 controls. Treg frequency was measured by flow cytometry; function was determined by T-cell proliferation assay. We also assessed the association between Treg frequency/function and clinical parameters in BA cases. RESULTS There was no significant difference between the two groups in both frequency (BA: 3.4%; control: 3.2%; p = 0.97) and function (BA: 22.0%; control: 7.5%; p = 0.23) of Tregs. We further focused on 13 preoperative BA patients and 14 age-matched controls. Neither Treg frequency nor function were significantly different (frequency: BA: 4.6%; control: 3.4%; p = 0.38, function: BA: 2.7%; control: 7.6%; p = 0.89). There was no association between Treg frequency/function and clinical parameters. CONCLUSION Neither the frequency nor function of circulating Tregs was affected in BA patients, suggesting the negative role of circulating Tregs in the pathogenesis of BA. Further investigation of local Treg profiles is warranted.

Abstract
The diagnosis of biliary atresia (BA) is mainly based on clinical manifestations, screening, and related biochemistry tests. In recent years, the development of blood biomarkers and the improvement in ultrasound examination have made it possible for BA to be diagnosed at a younger age. In particular, matrix metalloproteinase-7 shows high sensitivity and specificity and has a higher diagnostic efficiency than existing biochemical parameters, thereby holding a promise for clinical application. Sound touch elastography can increase the diagnostic efficiency for BA in terms of diagnosis and prognostic evaluation. Surgery is still the only method for the treatment of BA at present, with the preferred surgical treatment regimen of Kasai portoenterostomy combined with pharmacotherapies for alleviating infection and inflammation, and the patients who fail Kasai portoenterostomy or have liver dysfunction may require liver transplantation to save their lives. Therefore, the current research on BA should focus on the biomarkers for early diagnosis, specifically targeted drugs, and drugs for preventing progressive liver fibrosis. This article reviews the current diagnosis and treatment methods for BA and discusses the potential research directions.

Abstract
Biliary atresia, a fibro-obliterative disease of the newborn, is usually initially treated by Kasai portoenterostomy, although there are many variations in technique and different options for post-operative adjuvant medical therapy. A questionnaire on such topics (e.g., open vs. laparoscopic; the need for liver mobilisation; use of post-operative steroids; use of post-operative anti-viral therapy, etc.) was circulated to delegates (n = 43) of an international webinar (Biliary Atresia and Related Diseases-BARD) held in June 2021. Respondents were mostly European, but included some from North America, and represented 18 different countries overall. The results of this survey are presented here, together with a commentary and review from an expert panel convened for the meeting on current trends in practice.

Abstract
Objection: To explore the clinical features and prognosis of non-visualization of the fetal gallbladder (NVFGB). Methods: Sixty-five cases diagnosed with NVFGB in the Peking University First Hospital were collected retrospectively from January 2019 to December 2020. Results: Forty-nine cases were successfully followed up. Among them, the gallbladder of 21 fetuses (42.9%) was present in the later pregnancy. In the rest 28 cases (57.1%), the gallbladders were absent during the whole pregnancy. Eleven of twenty-eight fetuses (39.3%) with NVFGB were complicated with other structural anomalies. In the remaining 17 cases of isolated NVFGB (60.7%) during the whole pregnancy, there was one case of congenital biliary atresia, three cases of a small gallbladder, one case of gallstone and one case of the gallbladder with several septa inside. A total of nine cases (18.4%) underwent prenatal diagnosis, four of which revealed abnormal copy number variant (CNV) results. Conclusion: Nearly half of NVFGB could be noted during the later pregnancy. The persistent NVFGB during the pregnancy has a higher risk to complicate gallbladder abnormality, other structural anomalies and abnormal CNV results. Other structures, especially the heart, gastrointestinal and urinary system, should be carefully examined when NVFGB is suspected.

Abstract
Hyaluronic acid (HA), type III procollagen III (PC-III), type IV collagen IV (IV-C), and laminin (LN) have certain diagnostic value for hepatobiliary diseases. No published studies have compared the diagnostic accuracy of these 4 indicators for the diagnosis of congenital biliary atresia (CBA) in infants. This study aimed to investigate the diagnostic value of HA, PC-III, IV-C, and LN in infants with CBA. From January 2017 to December 2020, 185 infants with nonphysiological jaundice in the Second Department of General Surgery at the Children's Hospital of Hebei were enrolled in this study. Forty-six infants with CBA (CBA group) and 139 infants without CBA (noncongenital biliary atresia group) were diagnosed using ultrasonography, magnetic resonance imaging, intraoperative exploration, and intraoperative cholangiography. The levels of HA, PC-III, IV-C, and LN in the 2 groups were statistically analyzed. The diagnostic accuracy was determined using receiver operating characteristic curves and by calculating the area under the curve. Univariate and multivariate logistic regression analyses were performed to identify the independent risk factors. Compared to the noncongenital biliary atresia group, the levels of HA, PC-III, IV-C, and LN were significantly increased in the CBA group (P <.05). The receiver operating characteristic analysis showed the optimal cutoff values for HA, PC-III, IV-C, and LN were 162.7, 42.5, 199.7, and 101.2 ng/mL, and the area under the curves were 0.892, 0.762, 0.804, and 0.768, respectively. The sensitivity values for the diagnosis of CBA were 76.82%, 71.61%, 70.32%, and 72.28%, and the specificity values for the diagnosis of biliary atresia were 70.22%, 70.44%, 66.34%, and 68.71%, respectively. In the multivariate model, HA ≥162.7 ng/mL (odds ratio [OR] = 5.28, 95% confidence interval [CI]: 3.15-8.37), PC-III ≥42.5 ng/mL (OR = 4.61, 95% CI: 2.54-7.16), IV-C ≥199.7 ng/mL (OR = 5.02, 95% CI: 2.98-7.64), and LN ≥101.2 ng/mL (OR = 6.25, 95% CI: 2.41-10.07) remained associated with the occurrence of CBA. HA, PC-III, IV-C, and LN have high accuracy for the diagnosis of CBA in infants, and these factors are potential diagnostic biomarkers for CBA.

Primary Liver Transplantation vs. Transplant after Kasai Portoenterostomy for Infants with Biliary Atresia. J Clin Med 2022; 11:jcm11113012. [PMID: 35683401 PMCID: PMC9181323 DOI: 10.3390/jcm11113012] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2022] [Revised: 05/04/2022] [Accepted: 05/23/2022] [Indexed: 02/04/2023] Open
Abstract
Introduction: Primary liver transplants (pLT) in patients with biliary atresia (BA) are infrequent, since most babies with BA undergo a prior Kasai portoenterostomy (KPE). This study compared transplant outcomes in children with BA with or without a prior KPE. We hypothesized that pLT have less morbidity and better outcomes compared to those done after a failed KPE. Methods: A retrospective review of patients with BA transplanted at our institution was performed. Patients were included if they received a pLT or if they were transplanted less than 2 years from KPE. Outcomes were compared between those groups. Comparisons were also made based on era (early: 1997−2008 vs. modern: 2009−2020). p < 0.05 was considered significant. Results: Patients who received a pLT were older at diagnosis (141.5 ± 46.0 vs. KPE 67.1 ± 25.5 days, p < 0.001). The time between diagnosis and listing for transplant was shorter in the pLT group (44.5 ± 44.7 vs. KPE 140.8 ± 102.8 days, p < 0.001). In the modern era, the calculated PELD score for the pLT was significantly higher (23 ± 8 vs. KPE 16 ± 8, p = 0.022). Two waitlist deaths occurred in the KPE group (none in pLT, p = 0.14). Both the duration of transplant surgery and transfusion requirements were similar in both groups. There was a significant improvement in graft survival in transplants after KPE between eras (early era 84.3% vs. modern era 97.8%, p = 0.025). The 1-year patient and graft survival after pLT was 100%. Conclusions: Patient and graft survival after pLT are comparable to transplants after a failed KPE but pLT avoids a prior intervention. There was no significant difference in pre- or peri-transplant morbidity between groups other than wait list mortality. A multicenter collaboration with more patients may help demonstrate the potential benefits of pLT in patients predicted to have early failure of KPE.

Abstract
Biliary atresia (BA) is a devastating liver disease in neonates. Liver fibrosis is regarded as a universal and prominent feature of BA. Studies have revealed that long non-coding RNAs (lncRNAs) regulate cellular processes during the development of liver fibrosis in BA. Long non-coding RNA-adducin 3 antisense RNA1 (lnc-ADD3-AS1) has been shown to increase susceptibility to BA. However, the role of lnc-ADD3-AS1 in liver fibrosis in BA remains unclear. Here, we investigated the role of lnc-ADD3-AS1 in the proliferation, migration, and apoptosis of the immortalized human hepatic stellate cell (HSC) line, LX-2. We successfully overexpressed and silenced lnc-ADD3-AS1 in LX-2 cells using adenovirus vectors and evaluated the proliferation of transfected cells using the Cell Counting Kit-8 (CCK8) assay. Cell apoptosis was detected using annexin V-fluorescein isothiocyanate (FITC)/propidium iodide (PI) double staining and flow cytometry. We then analyzed cell migration by performing wound-scratch and transwell migration assays. Our results show that lnc-ADD3-AS1 significantly promoted LX-2 cell proliferation and attenuated apoptosis. More importantly, lncRNA-ADD3-AS1 significantly accelerated the migration of LX-2 cells. Our data indicated that lncRNA-ADD3-AS1 plays a role in the pathogenesis of liver fibrosis in patients with BA and may serve as a potential diagnostic marker for monitoring liver fibrosis in BA or as a therapeutic target for the disease.

Abstract
Congenital anomalies of the liver, biliary tree and pancreas are rare birth defects, some of which are characterized by a marked variation in geographical incidence. Morphogenesis of the hepatobiliary and pancreatic structures initiates from two tubular endodermal evaginations of the most distal portion of the foregut. The pancreas develops from a larger dorsal and a smaller ventral outpouching; emergence of the two buds will eventually lead to the fusion of the duct system. A small part of the remaining ventral diverticulum divides into a "pars cystica" and "pars hepatica", giving rise to the cystic duct and gallbladder and the liver lobes, respectively. Disruption or malfunctioning of the complex mechanisms leading to the development of liver, gallbladder, biliary tree and pancreas can result in numerous, albeit fortunately relatively rare, congenital anomalies in these organs. The type and severity of anomalies often depend on the exact moment in which disruption or alteration of the embryological mechanisms takes place. Many theories have been brought forward to explain their embryological basis; however, no agreement has yet been reached for most of them. While in some cases pathological evaluation might be more centered on macroscopic evaluation, in other instances small biopsies will be the keystone to understanding organ function and treatment results in the context of congenital anomalies. Thus, knowledge of the existence and histopathological characteristics of some of the more common conditions is mandatory for every pathologist working in the field of gastrointestinal pathology.

Abstract
Background: Biliary atresia (BA) is considered to be an autoimmune-mediating inflammatory injury. The pathogenesis of BA has been proposed with the clonal transformation of T cells expressing analogous T-cell receptor β-chain variable regions (TRBVs). Methods: The TRBV profile of the peripheral blood mononuclear cells (PBMCs) in infants with BA and control infants (healthy donors, HDs), respectively, were characterized by using high-throughput sequencing (HTS). The diversity of T cells was analyzed based on the frequency of complementarity-determining region 3 (CDR3) or V(CDR3)J. Moreover, the correlation between absolute lymphocyte count (ALC) and lactate dehydrogenase (LDH) or diversity (clonality) indices, respectively, were analyzed for subjects with BA and HD. Results: The diversity indices of CDR3, V(CDR3)J in BA are lower than those in subjects with HD, in addition, there are significantly different levels of neutrophile, neutrophile/lymphocyte ratio (NLR), and LDH between groups of BA and HD. The correlation between ALC and diversity index is significant in subjects with HD but is not for subjects with BA. Conversely, the relationship between ALC and LDH is significant in subjects with BA but is not for subjects with HD. Moreover, 12 CDR3 motifs are deficient or lower expression in BA compared with that in the HD group. Conclusion: Our results demonstrate that the profile of TRBV repertoire is significantly different between subjects with BA and HD, and suggest that the immune imbalance and elevated LDH level are associated with the pathogenesis of BA. Moreover, the values of neutrophile, NLR, and LDH could be used for the differential diagnosis of BA.

Abstract
Biliary atresia is a rare inflammatory sclerosing obstructive cholangiopathy that initiates in infancy as complete choledochal blockage and progresses to the involvement of intrahepatic biliary epithelium. Growing evidence shows that biliary atresia is not a single entity with a single etiology but a phenotype resulting from multifactorial events whose common path is obliterative cholangiopathy. The etiology of biliary atresia has been explained as resulting from genetic variants, toxins, viral infection, chronic inflammation or bile duct lesions mediated by autoimmunity, abnormalities in the development of the bile ducts, and defects in embryogenesis, abnormal fetal or prenatal circulation and susceptibility factors. It is increasingly evident that the genetic and epigenetic predisposition combined with the environmental factors to which the mother is exposed are potential triggers for biliary atresia. There is also an indication that a progressive thickening of the arterial middle layer occurs in this disease, suggestive of vascular remodeling and disappearance of the interlobular bile ducts. It is suggested that the hypoxia/ischemia process can affect portal structures in biliary atresia and is associated with both the extent of biliary proliferation and the thickening of the medial layer.

Abstract
Biliary Atresia, a common basis for neonatal cholestasis and primary indication for Liver Transplantation, accounts for 60% of pediatric Liver Transplantations. While the pathogenesis of Biliary Atresia remains obscure, abnormalities within bile ducts and the liver, inflammation, fibrosis and cilia defects are thought to comprise the pathological basis for this condition. The findings of genetic variants in Biliary Atresia, such as Copy Number Variations and Single Nucleotide Polymorphism, are considered as essential factors in the development of this condition. In this review, we summarize and analyze these Biliary Atresia variants from a perspective of their pathological characteristics. In conclusion, such analyses may offer novel insights into the pathogenesis of Biliary Atresia and provide a foundation for future studies directed toward a better understanding and treatment of Biliary Atresia.

Abstract
BACKGROUND The failed clearance of jaundice (CJ) in patients with biliary atresia (BA) after the Kasai procedure (KP) often leads to a shorter native liver survival (NLS) time and earlier liver transplantation. We aimed to investigate risk factors of failed CJ and establish a novel nomogram model to predict the status of CJ. METHODS We retrospectively reviewed institutional medical records from January 2015 to April 2020 and enrolled BA patients post-KP, randomly divided into training and testing cohorts at a ratio of 7:3, and further subdivided into cleared and uncleared jaundice groups. Univariate and multiple logistic regression analyses were used to select risk factors to establish the nomogram in the training cohort. The performance of the nomogram was evaluated by calculating the areas under the receiver operating curve (AUC) in both cohorts. RESULTS This study included 175 BA patients post-KP. After univariate and multiple logistic regression analyses, Cytomegalovirus IgM +ve associated BA (OR = 3.38; 95% CI 1.01-11.32; P = 0.04), ln γ-glutamyl transpeptidase (GGT) (OR = 0.41; 95% CI 0.22-0.80; P = 0.009), thickness of the fibrous portal plate (OR = 0.45; 95% CI 0.27-0.76; P = 0.003), liver stiffness measurement (LSM) (OR = 1.19; 95% CI 1.06-1.34; P = 0.002), and multiple episodes of cholangitis (OR = 1.65; 95% CI 1.13-2.41; P = 0.01) were identified as independent risk factors of unsuccessful CJ to construct the nomogram. The receiver operating characteristic curve (ROC) analysis suggested good nomogram performance in both the training (AUC = 0.96) and testing cohorts (AUC = 0.91). CONCLUSION Our nomogram model including several risk factors effectively predicts CJ in patients post-KP, which could aid in clinical decision-making.

Abstract
"Biliary atresia (BA) is a common cause of jaundice in infancy. There is increasing evidence that newborn screening with direct or conjugated bilirubin leads to earlier diagnosis. Although the Kasai portoenterostomy is the primary treatment, there are scientific advances in adjuvant therapies. As pediatric patients transition to adult care, multidisciplinary care is essential, given the complexity of this patient population."

Abstract
BACKGROUND Despite surgical treatment, children with biliary atresia (BA) may face many problems which seriously affect their quality of life. However, there is a paucity of studies in China examining the quality of life of these children after BA treatment. This study investigated the current status of the quality of life of children after BA treatment and analyzed the influencing factors so as to provide a scientific basis for the development of targeted interventional measures. METHODS From May 1 to May 31, 2021, the STAR questionnaire method was used to conduct cross-sectional surveys in children following BA surgery in the West China Hospital of Sichuan University, China. The basic information questionnaire was used to investigate the general characteristics of the children. The children were also given quality of life questionnaires during follow-up sessions after surgical treatment for BA. In addition, a 12-point health survey was used to assess the physical and mental health of the children's caregivers. Age- and gender-matched healthy children were recruited as controls. Correlation analysis and multiple linear regression equations were established to explore the influencing factors of the quality of life of children after surgery for BA. RESULTS After surgery, children with BA experienced significantly lower physical health, emotional function, social function, cognitive function, and quality of life compared to healthy children (P<0.050). Co-existing diseases had a statistically significant impact on the quality of life of children with BA (b=-12.566; t=-2.343; P=0.021), and the caregiver's understanding level of liver transplantation also had a statistically significant impact on the quality of life of these children (b=6.481; t=2.376; P=0.021). CONCLUSIONS The quality of life of children after BA surgery was significantly lower than that of age-matched healthy children. Co-existing diseases and the caregiver's understanding level of liver transplantation were the main factors affecting the quality of life of these children.

Abstract
BACKGROUND AND AIMS Biliary atresia (BA) is a devastating cholangiopathy of infancy. Upon diagnosis, surgical reconstruction by Kasai hepatoportoenterostomy (HPE) restores biliary drainage in a subset of patients, but most patients develop fibrosis and progress to end-stage liver disease requiring liver transplantation for survival. In the murine model of BA, rhesus rotavirus (RRV) infection of newborn pups results in a cholangiopathy paralleling that of human BA. High-mobility group box 1 (HMGB1) is an important member of the danger-associated molecular patterns capable of mediating inflammation during infection-associated responses. In this study, we investigated the role of HMGB1 in BA pathogenesis. APPROACH AND RESULTS In cholangiocytes, RRV induced the expression and release of HMGB1 through the p38 mitogen-activated protein kinase signaling pathway, and inhibition of p38 blocked HMGB1 release. Treatment of cholangiocytes with ethyl pyruvate suppressed the release of HMGB1. Administration of glycyrrhizin in vivo decreased symptoms and increased survival in the murine model of BA. HMGB1 levels were measured in serum obtained from infants with BA enrolled in the PROBE and START studies conducted by the Childhood Liver Disease Research Network. High HMGB1 levels were found in a subset of patients at the time of HPE. These patients had higher bilirubin levels 3 months post-HPE and a lower survival of their native liver at 2 years. CONCLUSIONS These results suggest that HMGB1 plays a role in virus induced BA pathogenesis and could be a target for therapeutic interventions in a subset of patients with BA and high HMGB1.

Abstract
BACKGROUND This study aimed to assess the utility of magnetic resonance imaging (MRI) in the diagnosis of prenatal non-visualization of the fetal gallbladder (PNVGB). MATERIAL AND METHODS The clinical data of 32 pregnant women with PNVGB who underwent MRI examination during the second and third trimester of pregnancy were collected and their outcomes were analyzed. RESULTS MRI showed that 26 patients (81.3%) had isolated PNVGB and 6 (18.8%) had additional malformations. In 26 patients with isolated PNVGB, 7 were found in the gallbladder on MRI and 4 were found on subsequent ultrasonography. One patient had termination of pregnancy (TOP) and 1 patient was lost to follow-up; the remaining 24 patients were known to deliver a healthy child. Among the 6 patients with additional malformations, 3 terminated their pregnancies due to combined severe abnormalities: 1 patient with horseshoe kidney and 1 with fetal echogenic bowel both had a healthy child, while 1 with fetal growth restriction (FGR) delivered a child who walked on tiptoe. CONCLUSIONS MRI contributes to identifying PNVGB detected or suspected by ultrasonography.

Sequential Treatment of Biliary Atresia With Kasai Hepatoportoenterostomy and Liver Transplantation: Benefits, Risks, and Outcome in 393 Children. Front Pediatr 2021; 9:697581. [PMID: 34307260 PMCID: PMC8292612 DOI: 10.3389/fped.2021.697581] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Accepted: 05/25/2021] [Indexed: 11/13/2022] Open
Abstract
Introduction: Surgical treatment of biliary atresia (BA) is still based on sequential strategy with Kasai hepatoportoenterostomy (KP) followed by liver transplantation (LT), in case of complicated secondary biliary cirrhosis. Concerns have been expressed regarding the risks of LT related to previous KP, suggesting primary LT as an exclusive treatment of BA. Methods: Single-center retrospective analysis including 393 pediatric patients who underwent LT for BA from 1993 to 2018, categorized into two groups: with (KP) or without (NoKP) previous KP. Pre-LT clinical condition was estimated considering age at LT, time on waiting list, pediatric end-stage liver disease score (PELD), and presence of portal vein hypoplasia. Post-LT outcome was evaluated considering patient and graft survival rates, and need for early reoperation due to abdominal or graft-related complications (<45 days after LT). Results: Two-hundred ninety-six patients (75.3%) were categorized in the KP group, and 97 (24.7%) in the NoKP group. Median age at LT was 1.14 years in the KP group and 0.85 years in the NoKP group (p < 0.0001). PELD score was significantly less severe in KP patients (p < 0.05). One-year patient survival rates were 96.9 and 96.8% in the KP and NoKP groups, respectively (p = 0.43), and the corresponding graft survival was 92.5 and 94.8% (p = 0.97). The need for early reoperation was more frequent in the KP group (29.8%) vs. NoKP group (12.4%, p = 0.01). The rate of bowel perforation was non-significantly higher in the KP group (8.1%) vs. NoKP group (3.1%, p = 0.11). Conclusions: The sequential strategy including KP and LT allowed performing LT in patients with significant older age and better clinical conditions, when compared to those transplanted without previous KP. Patient and graft survivals were not impacted by previous KP. Although previous KP was associated with an increased rate of post-LT surgical complications, bowel perforation and bleeding did not occur significantly more frequently. Such results support the current strategy based on sequential treatment.

Biological and Histological Assessment of the Hepatoportoenterostomy Role in Biliary Atresia as a Stand-Alone Procedure or as a Bridge toward Liver Transplantation. ACTA ACUST UNITED AC 2020; 57:medicina57010016. [PMID: 33379246 PMCID: PMC7823821 DOI: 10.3390/medicina57010016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2020] [Revised: 12/07/2020] [Accepted: 12/23/2020] [Indexed: 02/05/2023]
Abstract
Background and objectives: In patients with biliary atresia (BA), hepatoportoenterostomy (HPE) is still a valuable therapeutic tool for prolonged survival or a safer transition to liver transplantation. The main focus today is towards efficient screening programs, a faster diagnostic, and prompt treatment. However, the limited information on BA pathophysiology makes valuable any experience in disease management. This study aimed to analyze the evolution and survival of patients with BA referred for HPE (Kasai operation) in our department. Materials and Methods: A retrospective analysis was performed on fourteen patients with BA, diagnosed in the pediatric department and further referred for HPE in our surgical department between 2010 and 2016. After HPE, the need for transplantation was assessed according to patients cytomegalovirus (CMV) status, and histological and biochemical analysis. Follow-up results at 1–4 years and long term survival were assessed. Results: Mean age at surgery was 70 days. Surgery in patients younger than 60 days was correlated with survival. Jaundice’s clearance rate at three months was 36%. Total and direct bilirubin values had a significant variation between patients with liver transplants and native liver (p = 0.02). CMV was positive in eight patients, half with transplant need and half with native liver survival. Smooth muscle actin (SMA) positivity was proof of advanced fibrosis. The overall survival rate was 79%, with 75% for native liver patients and an 83% survival rate for those with liver transplantation. Transplantation was performed in six patients (43%), with a mean of 10 months between HPE and transplantation. Transplanted patients had better survival. Complications were diagnosed in 63% of patients. The mean follow-up period was six years. Conclusions: HPE, even performed in advanced cirrhosis, allows a significant survival, and ensures an essential time gain for patients requiring liver transplantation. A younger age at surgery is correlated with a better outcome, despite early CMV infection.

Abstract
Cholestasis describes impairment in bile formation or flow which can manifest clinically with fatigue, pruritus, and jaundice. The differential diagnosis of cholestatic liver diseases is broad, and the etiologies of cholestasis vary in the anatomical location of the defect and acuity of presentation. Cholestasis may occur in a variety of clinical scenarios. Therefore, it is important for a diverse audience with varied clinical practices to have a basic understanding of manifestations of cholestatic liver diseases.

Abstract
Biliary atresia (BA) is an idiopathic neonatal cholestatic disease. Recent genome-wide association study (GWAS) revealed that common variation of ADD3, GPC1, ARF6, and EFEMP1 gene was associated with BA susceptibility. We aimed to evaluate the association of these genes with BA in Chinese population. Twenty single nucleotide polymorphisms (SNPs) in these four genes were genotyped in 340 BA patients and 1,665 controls. Three SNPs in ADD3 were significantly associated with BA, and rs17095355 was the top SNP (PAllele = 3.23×10-6). Meta-analysis of published data and current data indicated that rs17095355 was associated with BA susceptibility in Asians and Caucasians. Three associated SNPs were expression quantitative trait loci (eQTL) for ADD3. Two GPC1 SNPs in high linkage disequilibrium (LD) showed nominal association with BA susceptibility (PAllele = 0.03 for rs6707262 and PAllele = 0.04 for rs6750380), and were eQTL of GPC1. Haplotype harboring these two SNPs almost reached the study-wide significance (P = 0.0035). No association for ARF6 and EFEMP1 was found with BA risk in the current population. Our study validated associations of ADD3 and GPC1 SNPs with BA risk in Chinese population and provided evidence of epistatic contributions of genetic factors to BA susceptibility.

Abstract
Aim Increasing evidence indicates that hepatic subcapsular flow (HSF) can serve as a noninvasive ultrasonographic marker for the early diagnosis of biliary atresia (BA). However, results regarding its diagnostic accuracy are inconsistent and inconclusive. We conducted this meta-analysis with an aim to systematically evaluate the diagnostic value of HSF in predicting BA. Methods A comprehensive literature search of four databases was conducted to identify the eligible studies. All analyses were performed using STATA 12.0. Results Nine studies from eight articles containing 368 patients and 469 controls were included in our meta-analysis. Briefly, the values for pooled sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and area under the curve (AUC) were 0.95 (95% CI 0.88-0.98), 0.92 (95% CI 0.85-0.96), 11.6 (95% CI 6.3-21.5), 0.06 (95% CI 0.02-0.14), 201 (95% CI 59-689), and 0.98 (95% CI 0.96-0.99), respectively. Additionally, metaregression along with subgroup analysis based on various covariates revealed the potential sources of heterogeneity and the detailed diagnostic value in each subgroup. Conclusion Our meta-analysis showed that HSF assay could provide high accuracy in predicting BA patients and non-BA individuals. However, further studies with better design and larger sample size are required to support the results of the present study.

Abstract
Biliary atresia (BA) is a devastating fibro-inflammatory disease characterized by the obstruction of extrahepatic and intrahepatic bile ducts in infants that can have fatal consequences, when not treated in a timely manner. It is the most common indication of pediatric liver transplantation worldwide and the development of new therapies, to alleviate the need of surgical intervention, has been hindered due to its complexity and lack of understanding of the disease pathogenesis. For that reason, significant efforts have been made toward the development of experimental models and strategies to understand the etiology and disease mechanisms and to identify novel therapeutic targets. The only characterized model of BA, using a Rhesus Rotavirus Type A infection of newborn BALB/c mice, has enabled the identification of key cellular and molecular targets involved in epithelial injury and duct obstruction. However, the establishment of an unleashed chronic inflammation followed by a progressive pathological wound healing process remains poorly understood. Like T cells, macrophages can adopt different functional programs [pro-inflammatory (M1) and resolutive (M2) macrophages] and influence the surrounding cytokine environment and the cell response to injury. In this review, we provide an overview of the immunopathogenesis of BA, discuss the implication of innate immunity in the disease pathogenesis and highlight their suitability as therapeutic targets.

Abstract
Long non-coding RNAs (lncRNAs) are RNAs with lengths exceeding 200 nucleotides that are not translated into proteins. It is well-known that small non-coding RNAs, such as microRNAs (miRNAs), regulate gene expression and play an important role in cholangiopathies. Recent studies have demonstrated that lncRNAs may also play a key role in the pathophysiology of cholangiopathies. Patients with cholangiopathies often develop cholangiocarcinoma (CCA), which is cholangiocyte-derived cancer, in the later stage. Cholangiocytes are a primary target of therapies for cholangiopathies and CCA development. Previous studies have demonstrated that expression levels of lncRNAs are altered in the liver of cholangiopathies or CCA tissues. Some lncRNAs regulate gene expression by inhibiting functions of miRNAs leading to diseased liver conditions or CCA progression, suggesting that lncRNAs could be a novel therapeutic target for those disorders. This review summarizes current understandings of functional roles of lncRNAs in cholangiopathies and seek their potentials for novel therapies.

[PMID: 31271681 DOI: 10.1111/jgh.14777] [Citation(s) in RCA: 33] [Impact Index Per Article: 8.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2018] [Revised: 06/04/2019] [Accepted: 07/01/2019] [Indexed: 01/09/2023]
Abstract
BACKGROUND AND AIM Biliary atresia (BA) is a progressive fibro-inflammatory cholangiopathy with an unclear etiology. Various liver disorders are associated with an altered microbiome. However, gut microbiome in BA remains unknown. Here, we performed a case-control study to investigate the gut microbiota in BA. METHODS A cross-sectional analysis was first conducted for 34 BA patients and 34 healthy controls. Then we investigated the shift in gut microbiota 2 weeks after the Kasai procedure in 16 BA patients. Gut microbiome was initially analyzed using 16S ribosome RNA gene sequencing and further validated by metagenomic sequencing. Fecal bile acids were determined using ultra-high performance liquid chromatography. RESULTS Compared with healthy controls, BA showed lower diversity and significant structural segregation in the microbiome. At phylum level, Proteobacteria numbers increased, whereas those of Bacteroidetes decreased in BA. At genus level, several potential pathogens such as Streptococcus and Klebsiella thrived in BA, while numbers for Bifidobacterium and several butyrate-producing bacteria declined. The microbiome was also disturbed after the Kasai procedure. Operational taxonomic units responding to BA showed significant correlation with liver function. Furthermore, the abundance ratio of Streptococcus/Bacteroides showed great promise in distinguishing BA from healthy controls. Intestinal bile acids were dramatically decreased in BA, and Clostridium XIVa positively correlated with the ratio of primary/secondary bile acids. CONCLUSIONS Gut microbial dysbiosis, may be caused by decreased bile acids, was associated with liver function and had a good diagnostic potential for BA. Therefore, further exploration of gut microbiota may provide important insights into their potential diagnostic and therapeutic benefits.

Abstract
PURPOSE Kasai portoenterostomy (KP) is the primary procedure for biliary atresia (BA). However, due to reports of poor outcomes of KP, primary liver transplantation (LT) is preferred in selected cases. In Japan, primary LT is limited with no study reports details, particularly regarding the indications. We conducted the first nationwide survey to assess the status of primary LT in Japan. METHODS Questionnaires were sent to institutions where procedures other than KP were performed as the initial procedure for BA and registered to the Japan Biliary Atresia Registry. Parameters related to procedure selection were analyzed. RESULTS Of 2895 patients registered (1989-2013), primary LT (n = 15) or exploratory laparotomy (EL) followed by LT (n = 9) without KP was performed in 24 cases (0.8%). The main reason for primary LT was late diagnosis, and for EL followed by LT, lack of fibrous tissue at the porta hepatis (ο-type). The prognoses of LT without KP was good. CONCLUSION Non-KP initial procedures were limited. Clear criteria regarding the timing of diagnosis or patient condition could not be determined. Reasons for not initially selecting KP varied, but late diagnosis was predominant. Further study is needed to create guidelines for the initial treatment of BA patients.

Quantitative Contrast-Enhanced Ultrasound by Sonazoid in the Early Diagnosis of Biliary Atresia: An Experimental Study of Rats With Bile Duct Ligation. ULTRASOUND IN MEDICINE & BIOLOGY 2019; 45:2767-2776. [PMID: 31345651 DOI: 10.1016/j.ultrasmedbio.2019.06.409] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/13/2018] [Revised: 06/08/2019] [Accepted: 06/19/2019] [Indexed: 06/10/2023]
Abstract
We aimed to investigate the feasibility of quantitative Sonazoid contrast-enhanced ultrasound (CEUS) in the diagnosis of biliary atresia (BA) at an early disease stage. First, liver tissue from 10 patients with BA and 10 patients with infantile hepatitis syndrome (IHS) was immunostained with cluster of differentiation 68 (CD68) to compare Kupffer cell counts. Then, quantitative Sonazoid CEUS was performed to evaluate the hyperplasia of the artery branches during the artery phase and changes in Kupffer cell counts during the Kupffer phase in a rat model of BA (common bile duct ligation). Based on our results, liver enhancement from Kupffer cells in BA patients was significantly higher than that in IHS patients (p = 0.026 < 0.05). Furthermore, quantitative CEUS showed that the liver enhancement intensity of rats with bile duct ligation was substantially greater than that of rats without bile duct ligation during the artery phase 3 d post-operation and the Kupffer phase 5 d post-operation. The increased enhancement intensity in the Kupffer phase was in agreement with the increase in Kupffer cell counts in pathologic staining (18/20, 90%). In conclusion, quantitative Sonazoid CEUS can detect the hyperplasia of artery branches in artery phase and the increase of Kupffer cells in Kupffer phase in the liver of BA rats at an early disease stage. Therefore, Sonazoid CEUS could potentially be a valuable non-invasive alternative for the diagnosis of BA.

Five-year native liver survival analysis in biliary atresia from a single large Chinese center: The death/liver transplantation hazard change and the importance of rapid early clearance of jaundice. J Pediatr Surg 2019; 54:1680-1685. [PMID: 30518490 DOI: 10.1016/j.jpedsurg.2018.09.025] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/19/2018] [Revised: 08/22/2018] [Accepted: 09/18/2018] [Indexed: 12/19/2022]
Abstract
PURPOSE This study aimed to analyze the change of death/liver transplantation hazard and biochemical indexes over time after Kasai procedure (KP) based on a retrospective biliary atresia (BA) cohort, and to evaluate the predictive value of early jaundice clearance rate to 5-year native liver survival (NLS). METHODS A retrospective cohort with follow-up results of 139 BA patients from January 2009 to December 2012 was established, and the pre- and postoperative data were collected. NLS rates were estimated with Kaplan-Meier curves, and any differences between groups were tested by log-rank test. Hazard curve of death/liver transplantation was fitted with Weibull distribution, and hazards at certain time points were calculated. Trend charts of biochemical indexes were drawn to show any changes over time. Rate of jaundice clearance was indicated as the proportion of decreased total bilirubin level at a certain postoperative time point to preoperative total bilirubin level. In multivariate analysis for prediction of 5-year NLS, COX proportional hazard regression model was used and results were expressed as hazard ratios with 95% confidence intervals (CIs). The predictive value of early jaundice clearance rates for 5-year NLS was analyzed by receiver operating characteristic (ROC) curve, and a cut-off value of 4-week jaundice clearance rate was determined. RESULTS The estimated 5-year NLS rate of the 139 patients was 58.0%. The patients had a high hazard of death/liver transplantation early after KP, which gradually decreased and stabilized at a lower level 1 year later. Most death/liver transplantation events occurred within 1 year after KP. The total bilirubin (TBIL), direct bilirubin (DBIL) and total bile acid (TBA) levels of successful Kasai group decreased continuously after KP, and the biggest decline was seen in the first month. The aspartate aminotransferase (AST), alanine aminotransferase (ALT) and γ-glutamyl transpeptidase (GGT) levels increased during the first month after KP and decreased continuously thereafter. All the biochemical indexes of successful Kasai group tended to stabilize within/close to normal range 1 year after KP. On the contrary, all the biochemical indexes of failed Kasai group fluctuated at obvious abnormal levels after KP. The estimated 5-year NLS rates of successful Kasai group and failed Kasai group were 90.1% and 10.7% (p = 0.000). The most significant clinical protective factor of 5-year NLS was 4-week jaundice clearance rate, revealed by COX proportional hazard regression model, and the HR was 0.089 (95%CI 0.018-0.432, p = 0.003). In predicting 5-year native liver survival, the largest area under ROC (AUROC) curve belonged to 4-week jaundice clearance rate, which was 0.731 (p = 0.000). A cut-off value of 0.457 was determined, with sensitivity 0.827, specificity 0.552, positive predictive value 0.720, and negative predictive value 0.696. NLS rates of patients divided by cut-off value showed significant statistical difference demonstrated by Kaplan-Meier curve and log-rank test (p = 0.000). CONCLUSIONS The 5-year death/liver transplantation hazard of biliary atresia patients reduces greatly and stabilizes 1 year after KP. A successful KP enables patients to achieve long-term stable normal biochemical indexes. A rapid clearance of jaundice is of great positive significance to 5-year NLS, and the 4-week jaundice clearance rate is of some predictive value. TYPE OF STUDY Prognosis study. LEVEL OF EVIDENCE Level II, retrospective study.

Abstract
INTRODUCTION The common predominant clinical features of cholangiopathies such as primary sclerosing cholangitis (PSC), primary biliary cholangitis (PBC), and biliary atresia (BA) are biliary damage/senescence and liver fibrosis. Curative therapies are lacking, and liver transplantation is the only option. An understanding of the mechanisms and pathogenesis is needed to develop novel therapies. Previous studies have developed various disease-based research models and have identified candidate therapeutic targets. Areas covered: This review summarizes recent studies performed in preclinical models of cholangiopathies and the current understanding of the pathophysiology representing potential targets for novel therapies. A literature search was conducted in PubMed using the combination of the searched term 'cholangiopathies' with one or two keywords including 'model', 'cholangiocyte', 'animal', or 'fibrosis'. Papers published within five years were obtained. Expert opinion: Access to appropriate research models is a key challenge in cholangiopathy research; establishing more appropriate models for PBC is an important goal. Several preclinical studies have demonstrated promising results and have led to novel therapeutic approaches, especially for PSC. Further studies on the pathophysiology of PBC and BA are necessary to identify candidate targets. Innovative therapeutic approaches such as stem cell transplantation have been introduced, and those therapies could be applied to PSC, PBC, and BA.

Abstract
PURPOSE OF REVIEW Biliary atresia is a poorly understood deadly disease. Genetic predisposition factors are suspected albeit not firmly established. This review summarizes recent evidence of genetic alterations in biliary atresia. RECENT FINDINGS Whole-genome association studies in biliary atresia patients identified four distinct predisposition loci with four different genes potentially involved in the disease occurrence. Variations in these genes were searched for, but none were found in patients with biliary atresia suggesting complex mechanisms. SUMMARY Despite decades since its description and decades of intensive researches, cause of biliary atresia disease remains enigmatic. The inheritance of biliary atresia is not Mendelian. Genetic predisposition factor is one of the explored fields to explain biliary atresia pathogenicity. Biliary atresia has been associated with several inborn syndromes, chromosome anomalies, and gene polymorphisms in specific populations. Four predisposition loci encompassing genes relevant to the disease have been identified, but no pathogenic variations were found in biliary atresia patients. Few reported cases of isolated biliary atresia manifestation in the context of known genetic diseases suggest coincidental findings. Alternatives to classic genetic alterations are proposed to explain genetic predisposition in biliary atresia including noncoding and epigenetic factors. Biliary atresia is most likely related to complex traits making its genetic exploration challenging.

Abstract
BACKGROUND & AIMS Biliary atresia (BA) is a neonatal obliterative cholangiopathy with high prevalence in south China. Accurate identification of BA among infants with obstructive jaundice is still difficult by noninvasive diagnostic tools. Th17 cells have been reported closely related with the development of BA, which suggest that Th17-associated cytokines were potential biomarkers for the diagnosis of BA patients. METHODS In the training study, 76 infants who were divided into 2 groups, including BA group (n = 31) and non-BA jaundice group (n = 45). Clinical and routine laboratory data were collected from all subjects. Totally 25 Th17-associated cytokines were tested and compared between groups. The diagnostic value of each differential cytokine was evaluated by the area under the receiver operating characteristic curve (AUC). The best potential diagnostic biomarker was further validated in a cohort including 68 jaundice infants from our partnering institution in a blinded fashion. RESULTS Data from the training study showed that gamma-glutamyl transferase (GGT) and clay stool would be helpful in the identification of BA patients in jaundice subjects. Th17-associated cytokines assay indicated that IL-17F, IL-10, macrophage inflammatory protein-3alpha (MIP3a), IL-22, IL-13, IL-33, IL-6, IL-17E, IL-27, IL-31, TNF-a and TNF-b were differentially expressed in BA patients, and the AUC of MIP3a was higher than other markers. MIP3a alone or combined with other laboratory data would significantly increase the diagnostic accuracy of BA. The diagnostic value of MIP3a was further confirmed in our validation study. CONCLUSION MIP3a alone or combined with other laboratory data would significantly increase the diagnostic accuracy of BA.

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
OBJECTIVES The aim of the study is to determine the prognosis of patients with biliary atresia after 2 years of native liver survival (NLS) and to identify prognostic factors for continued NLS after 2 years of age. METHODS We retrospectively analyzed perioperative, laboratory, and outcome parameters of all biliary atresia patients in The Netherlands between January 1987 and June 2015 with NLS of at least 2 years. We compared parameters between patients who continued to have their native liver (NLS+) to those who did not, either by transplant or death (NLS-). RESULTS We included 100 patients. Upon a median follow-up of 16.4 years, NLS ended in 37% by liver transplantation (LTx) and in 6% by (pre-transplant) mortality. NLS rates at 5, 10, 15, 18 years of age were 89%, 72%, 60%, 54%, respectively. Corresponding overall survival rates were 98%, 90%, 87%, 87%, respectively. Six months post-Kasai, NLS+ patients had higher clearance of jaundice (COJ) rate, significantly lower total and direct serum bilirubin, aspartate-aminotransferase and alkaline phosphatase levels, compared with NLS- patients (each P < 0.05). Cox regression could only assess a significant effect of COJ on continued NLS. Main indications for LTx after the age of 2 were irreversible jaundice and portal hypertension. CONCLUSIONS Eighty-seven percent of patients with 2-year NLS reach adult age and more than 50% with their native liver. A pre-transplant mortality of 6%, however, exists among patients who reach the age of 2 years with their native livers. Early life parameters, other than COJ, did not have a significant effect on continued NLS after 2 years of age.

Abstract
Cholestatic liver injury is characterized by damage induced on the biliary tree and cholangiocytes, the cells lining the biliary tree, thus they are termed "cholangiopathies". Cholangiopathies include diseases such as Primary Biliary Cholangitis, Primary Sclerosing Cholangitis, Biliary Atresia and Cholangiocarcinoma. These pathologies lack viable therapies and most patients are diagnosed during late stage disease progression (with the exception of Biliary Atresia, which is found shortly after birth). The lack of therapies for these diseases has put a significant burden on the need for liver transplantation as this is the only indicative "cure" for cholangiopathies. The molecular mechanisms for cholangiopathies have been extensively studied; however, and unfortunately, the lack of effective biomarkers and therapeutics remains. In this review article we highlight the latest studies to investigate the molecular mechanisms regulating cholangiopathies and the potential therapeutics that might be discovered.

Abstract
PURPOSE To identify genes potentially involved in the pathogenesis of bile duct obstruction in biliary atresia (BA). METHODS We used rhesus rotavirus (RRV) Balb/c mouse BA model to study BA. Liver and serum samples were harvested from BA and normal control (NC) groups at 1, 3, 5, 7, 10 and 14 days postinoculation. Serum total bilirubin (STB) and conjugated bilirubin (CB) were measured. Livers of each group at day 7 were used for a genome-wide expression analysis. Expression of TLR7 signaling pathway in liver was measured by immunohistochemical staining and western blotting, including expression of TLR7, activation of phosphorylated IRF7 and secretion of IFN-β, IL-1α and IL-6. Cell viability and survival rate after RRV infection were measured by using TLR7 knockdown human cholangiocarcinoma cell RBE. RESULTS STB was significantly elevated from day 5 postinoculation and CB was from day 7 postinoculation, while CK19 (the biomarker of biliary epithelial cells) expression by western blotting was decreased. By microarray analysis of liver tissues at day 7 postinoculation, TLR7 signaling pathway was up-regulated in BA mice. Based on the results of microarray analysis, the protein expression of TLR7 in the liver tissues of BA groups were found to be up-regulated from day 5 comparing to respective NC groups, although it was increased as pups aged in NC groups. And the level of p-IRF7 and secretion of cytokines were also statistically significant in BA groups. In vitro, TLR7 knockdown cell line showed less cellular proliferation and more susceptible to RRV infection. CONCLUSION By in vivo study, TLR7 signal pathway was up-regulated in BA group; by additional in vitro study, intact TLR7 signal pathway might have some protective abilities in BA pathogenesis.

Abstract
The aim of our study was to determine the impact of initial orientation for medical and surgical care of children with BA on procedures and outcomes of the first LT. We retrospectively analyzed charts of children with BA who underwent first LT between 2006 and 2015. Patients were divided into two groups for comparison: a single-center management group (from diagnosis to transplantation) and a secondarily referred group (children referred after failure of KP). We focused analysis on disease severity at transplantation, blood transfusion, and overall survival. One hundred and eighty-five children were included. The median delay between pretransplant check-up and transplantation was shorter in patients secondarily referred. A severe undernutrition was observed in 23.7% of children secondarily referred compared to 11.1% in children with a single-center management (P = .024). At transplantation, INR and factor V level were higher in single-center group patients (respectively, 67% vs 55%, P < .001 and 61% vs 49%, P = .002). The total of red blood cell and fresh frozen plasma administrated during procedure was two times higher in patients secondarily referred. Finally, patients with a single-center management had a higher overall 12 months of survival rate (92.1% vs 83.1%, P = .033). In a country without low-density population issues, the authors advocate an early referring to transplant center to further improving LT outcomes in children with BA.

Abstract
BACKGROUND A genome-wide association study in East Asians suggested a genetic association between biliary atresia (BA) and a cluster of variants within the Adducin 3 (ADD3) and ADD3 antisense RNA1 (ADD3-AS1) genes. Another study in Thai neonates reported an association between BA and rs17095355. To validate those findings, this study aimed to analyze the BA association with single nucleotide polymorphisms (SNPs) and the additive influence of ADD3 and ADD3-AS1 in Thai neonates. METHODS DNAs from 56 BA cases and 166 controls were genotyped for rs2501577, rs11194981, rs12268910 (ADD3) and rs17095355 (ADD3-AS1), using TaqMan PCR. Genotype distributions were compared between the groups, and SNP-SNP interactions were analyzed by combination of allelotypes. RESULTS The risk allele frequencies of rs2501577, rs11194981, and rs17095355 in the BA group were significantly higher than in the controls. Univariate analysis showed that recessive variants in the three SNPs were associated with BA risk at ORs of 1.81 (95% CI 1.32-2.50), 1.58 (95% CI 1.14-2.20) and 1.92 (95% CI 1.39-2.66), respectively. SNP-SNP interaction analysis showed that the SNP combination of the two genes rs17095355 and rs2501577 provided an additive increase in BA risk. CONCLUSION ADD3 and ADD3-AS1 variants increased susceptibility to BA, suggesting that these genes may play an additive role in the pathogenesis of the disease. In addition, these interactions may give a clue to the overexpression of the ADD3 protein in the liver of BA patients.

Abstract
AIM To investigate the prevalence and clinical significance of autoimmune liver disease (ALD)-related autoantibodies in patients with biliary atresia (BA).
METHODS Sera of 124 BA patients and 140 age-matched non-BA controls were assayed for detection of the following autoantibodies: ALD profile and specific anti-nuclear antibodies (ANAs), by line-blot assay; ANA and anti-neutrophil cytoplasmic antibody (ANCA), by indirect immunofluorescence assay; specific ANCAs and anti-M2-3E, by enzyme linked immunosorbent assay. Associations of these autoantibodies with the clinical features of BA (i.e., cytomegalovirus infection, degree of liver fibrosis, and short-term prognosis of Kasai procedure) were evaluated by Spearman’s correlation coefficient.
RESULTS The overall positive rate of serum autoantibodies in preoperative BA patients was 56.5%. ALD profile assay showed that the positive reaction to primary biliary cholangitis-related autoantibodies in BA patients was higher than that to autoimmune hepatitis-related autoantibodies. Among these autoantibodies, anti-BPO was detected more frequently in the BA patients than in the controls (14.8% vs 2.2%, P < 0.05). Accordingly, 32 (25.8%) of the 124 BA patients also showed a high positive reaction for anti-M2-3E. By comparison, the controls had a remarkably lower frequency of anti-M2-3E (P < 0.05), with 6/92 (8.6%) of patients with other liver diseases and 2/48 (4.2%) of healthy controls. The prevalence of ANA in BA patients was 11.3%, which was higher than that in disease controls (3.3%, P < 0.05), but the reactivity to specific ANAs was only 8.2%. The prevalence of ANCAs (ANCA or specific ANCAs) in BA patients was also remarkably higher than that in the healthy controls (37.9% vs 6.3%, P < 0.05), but showed no difference from that in patients with other cholestasis. ANCA positivity was closely associated with the occurrence of postoperative cholangitis (r = 0.61, P < 0.05), whereas none of the autoantibodies showed a correlation to cytomegalovirus infection or the stages of liver fibrosis.
CONCLUSION High prevalence of autoantibodies in the BA developmental process strongly reveals the autoimmune-mediated pathogenesis. Serological ANCA positivity may be a useful predictive biomarker of postoperative cholangitis.

Abstract
Introduction Biliary atresia is the main cause of death by hepatic failure and the main indication for liver transplant in children. This study aims to analyze the population with this diagnosis, treated between 2000 and 2015 at Hospital de São João. Material and Methods Descriptive, observational, and retrospective study, including the patients with biliary atresia, diagnosed and treated between January 1, 2000 and December 31, 2015. We analyzed epidemiologic, clinical, biochemical, and image data, as well as registered complications and present status. Results Eighteen patients were evaluated. The median age at time of Kasai portoenterostomy was 63 days of life, with better prognosis for those patients who had surgery before 72 days. The procedure was successful in 2/3 of cases. There was a significant association between recurrent cholangitis and survival. Five cases of transplant and 2 deaths, one of them after transplant, were registered. Survival with native liver was 77.8%, 72.2%, and 64.2% at 1, 5, and 10 years of follow-up, respectively. Discussion The presentation and evolution of patients was similar to other studies. However, there was a higher surgical success and survival rates at 5 and 10 years of follow-up than most series. Age at surgery and recurrence of cholangitis were the only factors significantly related to prognosis. Conclusion In spite of the low number of patients (1,125/year), our results were similar to those of other reference centers.

Abstract
Despite many years of research, the causes of biliary atresia still remain elusive. Infection, immune disorder, toxins or maternal microchimerism have been cited as potential triggers of biliary atresia. This is a rare disease with a stable incidence over the years although with sizeable ethnic variations. This stability suggests that environmental factors have in fact only a slight influence. During the search for etiologies, twin studies have often helped disentangle the genetic from the environmental. For this condition, twin studies have mainly demonstrated a lack of concordance between twins (either monozygotic or dizygotic), ruling out Mendelian, infectious or toxic causes. Indeed, for toxic or infectious embryopathy, the concordance for twins (especially monozygotic) is about 80%. Paradoxically, these data suggest that biliary atresia has neither a genetic nor an environmental cause. One way of severing the Gordian knot is to hypothesize a role for post zygotic somatic mutation, leading to genetic mosaicism (as a cause of biliary atresia). In recent years, post zygotic mutation has been identified as a cause of non-cancerous disease ranging from dysmorphic syndrome to specific organ abnormalities. A potential model for this condition could be post zygotic mutation or copy number variations in genes or regulatory regions, triggering the cascade of events leading to inflammatory and obliterative cholangiopathy. These events could be enhanced by genetic susceptibility explaining the ethnic variations. In these models, the rate of mosaicism in different parts of the liver could explain the success rate of the Kasai procedure. This hypothesis can be tested: as most children with biliary atresia are eligible for the Kasai procedure, genetic material from the liver and ductal plate can be collected easily. If the hypothesis is correct, whole genome sequencing or copy number variation studies at individual cell level should allow to identify the expected low level of genetic mosaicism. Thus, we hypothesize that postzygotic somatic mutation may play a part in the physiopathology of biliary atresia.

Abstract
BACKGROUND Some patients with biliary atresia (BA) have associated anomalies. Our study aimed to investigate the incidence of BA-associated malformations in mainland China, and compare the results with those reported in the Western literature. METHODS Clinical data were collected retrospectively from five medical centers in mainland China. BA patients were diagnosed and confirmed by laparotomy with intraoperative cholangiography and liver biopsy. Cases were divided into isolated type BA and BA with associated anomalies, including polysplenia, situs inversus, intestinal malrotation, and cardiovascular anomalies. RESULTS A total of 851 BA patients were recruited from Tianjin, Beijing, Wuhan, Guangzhou, and Shenzhen. Patients were grouped as follows: Type I, 13 cases (1.5%); Type II, five cases (0.6%); Type III, 833 cases (97.9%). Forty-two (4.94%) patients had 54 associated congenital abnormalities. The intra-abdominal anomalies included polysplenia (n = 4, 1 fusion between liver and spleen), situs inversus (n = 2), and intestinal malrotation (n = 3). The cardiovascular anomalies included atrial septal defect and ventricular septal defect (n = 29), patent foramen ovale (n = 1), patent ductus arteriosus (n = 4), and other cardiac malformations (n = 3, including coronary sinus dilation, left superior vena cava, Tetralogy of Fallot). CONCLUSION Our data showed that spleen anomaly is not as common as reported in the Western literature. The difference may suggests different genetic and environmental risk factors for BA.
