Development and post-Kasai procedure prognostic relevance of histological features for biliary atresia. BMC Pediatr 2023; 23:589. [PMID: 37993876 PMCID: PMC10664255 DOI: 10.1186/s12887-023-04413-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/23/2023] [Accepted: 11/09/2023] [Indexed: 11/24/2023] Open
Abstract
OBJECTIVES To validate an appropriate evaluation method of liver fibrosis assessment based on the unique pathological features of biliary atresia (BA) that could well predict its prognosis. METHODS A total of 68 patients with BA who underwent Kasai procedure (KP) and an intraoperative liver biopsy, followed up from January 2019 to December 2021, were recruited in a retrospective analysis. Ishak, Metavir, and BA-specific staging systems in relation to outcomes were analyzed using logistic regression, COX proportional hazard regression, Kaplan-Meier analysis, etc. RESULTS: Kaplan-Meier analysis determined a significant difference in native liver survival according to the BA-specific stage (p = 0.002). The ROC curve analysis for predicting prognosis showed that the AUC of BA-specific staging combined with iBALF and severe bile duct proliferation (BDP) (0.811, 95% CI: 0.710-0.913, p < 0.0001) was higher than BA-specific staging alone (0.755, 95% CI: 0.639-0.872, p < 0.001). CONCLUSIONS The BA-specific staging system reflects the condition of the liver fibrosis, and its combination with iBALF and severe BDP helps to better evaluate the prognosis of patients with BA.

Synergistic effects of cagA+ Helicobacter pylori co-infected with Opisthorchis viverrini on hepatobiliary pathology in hamsters. Acta Trop 2021; 213:105740. [PMID: 33159904 DOI: 10.1016/j.actatropica.2020.105740] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 10/26/2020] [Accepted: 10/27/2020] [Indexed: 12/12/2022]
Abstract
Human liver fluke infection caused by Opisthorchis viverrini is associated with several biliary diseases including cholangiocarcinoma (CCA). Recently, it was discovered that the liver fluke is a reservoir of Helicobacter pylori, particularly the cagA-positive strain (cytotoxin-associated gene A) in its gut. Given that two carcinogenic pathogens are associated with CCA development, however, the role of cagA-positive H. pylori in opisthorchiasis has not been clarified. The present study was therefore aimed to investigate histopathological changes of the biliary system in hamsters co-infected with O. viverrini and cagA-positive H. pylori or O. viverrini and cagA-negative H. pylori, with controls of O. viverrini, cagA-positive H. pylori, or cagA-negative H. pylori alone, over time. Major histopathological changes were systematically investigated. All pathological features were quantified/semi-quantified and compared among the experimental groups. The results showed that O. viverrini infection groups (O. viverrini, cagA-positive H. pylori and cagA-negative H. pylori) showed a high degree of eosinophil and mononuclear cell infiltration, lymphoid aggregation and granuloma. Specifically, O. viverrini co-infected with cagA-positive H. pylori presented significantly higher inflammatory scores than O. viverrini and O. viverrini with cagA-positive H. pylori. Proliferation and adaptive lesions such as hyperplasia, goblet cell metaplasia and dysplasia were detected only in O. viverrini infection groups. Dysplasia, the precancerous lesion of CCA, was observed in the first-order bile ducts, especially where the inflammation existed and was found earlier and more severely in O. viverrini with cagA-positive H. pylori than other groups. Similarly, the BrdU (bromodeoxyuridine) proliferation index was significantly higher in O. viverrini co-infected with cagA-positive H. pylori than O. viverrini and O. viverrini with cagA-negative H. pylori groups. Periductal fibrosis was a prominent histopathologic feature in chronic infection in O. viverrini infection groups. Multiple logistic regression showed that O. viverrini co-infected with cagA-positive H. pylori and the duration of infection were the most important factors associated with periductal fibrosis (OR 3.02, 95% CI 1.02-9.29, p = 0.04 and OR 3.82, 95% CI 2.61-5.97, p<0.001). This study demonstrates that the liver fluke co-infected with cagA-positive H. pylori induces severe biliary pathology that may predispose to cholangiocarcinogenesis.

Abstract
OBJECTIVES Atrophy of the left lateral segment (LLS) is often encountered in liver transplantation (LT) for biliary atresia (BA). To clarify the meaning of the heterogeneous atrophy, we compared the pathological characteristics of the LLS with the right posterior segment (RPS) of BA livers obtained during LT. METHODS Among the 116 patients with BA who underwent LT at our hospital between 2014 and 2018, 63 patients with persistent cholestasis after the Kasai portoenterostomy (KP) were selected. Three pathologists evaluated tissues from the LLS and RPS for 5 pathological parameters. Positive areas in whole-slide image observed as portal inflammation, fibrosis, cholestasis, and ductular reaction, were analyzed with automated image quantitation. Moreover, we examined the relationship between the pathological score and the Pediatric End-stage Liver Disease (PELD) score. RESULTS The median age at LT was 7 months (range 4-26 months). Inflammation and fibrosis were significantly greater in the LLS than in the RPS (P < 0.001, for both); however, there were no differences in cholestasis, ductular reaction, and hepatocellular damage (P = 0.3, 0.3, and 0.82). The same results were obtained in automated image quantitation. Moreover, the sums of the 5 pathological scores in the LLS showed a significant positive correlation with the PELD score (P = 0.016, rs = 0.3). CONCLUSIONS More severe inflammation and fibrosis without cholestasis were observed in the LLS. The segmental atrophy may not be associated with poor bile drainage, but with etiopathogenesis of BA. Moreover, the proper site for biopsy during KP could be the LLS.

Abstract
BACKGROUND/AIMS The present study aimed at investigating the long-term outcomes and prognostic factors of patients with biliary atresia (BA) diagnosed and followed at a single center. MATERIALS AND METHODS Patients with BA treated during 1994-2014 at a large-volume pediatric tertiary referral center were reviewed retrospectively with regard to demographic, clinical, laboratory, and diagnostic characteristics for identifying the prognostic factors and long-term clinical outcomes. RESULTS Overall, 81 patients (49 males, 32 females) were included. Mean age at diagnosis was 73.1±4.7 (median: 64) days. Of the patients included, 78 patients (96%) underwent a portoenterostomy procedure. Mean age at operation was 76.8±4.7 (median: 72) days. The surgical success rate was 64.8%. A younger age (either at diagnosis or surgery) was the only determinant of surgical success. The 2-, 5-, and 10-year overall survival (OS) rates, including all patients with or without liver transplantation, were 75%, 73%, and 71% respectively, whereas the 2-, 5-, and 10-year survival rates with native liver (SNL) were 69%, 61%, and 57%, respectively. Mean follow-up duration was 9.4±7.5 years. Successful surgery, presence of fibrosis and/or cirrhosis on the liver pathology, and prothrombin time [international normalized ratio (INR)] at presentation were independent prognostic factors for both OS and SNL. CONCLUSION A younger age at diagnosis is strongly associated with surgical success in BA. Surgical success, the prothrombin time (INR) at presentation, and liver pathology are independent prognostic factors affecting the long-term outcomes in patients with BA. Therefore, timely diagnosis and early referral to experienced surgical centers are crucial for optimal management and favorable long-term results in BA.

[PMID: 32296668 PMCID: PMC7136468 DOI: 10.3389/fped.2020.00131] [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] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/09/2020] [Accepted: 03/10/2020] [Indexed: 01/29/2023] Open
Abstract
Background: Several non-invasive markers have been reported as being effective for the assessment of fibrosis in adults with chronic viral hepatitis. The infantile liver is more susceptible to cholestasis, and it is important to promptly evaluate liver fibrosis to guide the clinical treatment. However, the clinical value of these markers in infants with cholestasis remains unknown. Aim: To investigate the correlation between serum laminin (LN), hyaluronic acid (HA), procollagen III N-terminal peptide (PIIINP) level, and liver fibrosis stage in infants with cholestasis. Methods: One hundred and thirty-seven term infants with cholestasis were included. Laparoscopic exploration and cholangiography were performed to diagnose or rule out biliary atresia. Serum LN, HA, and PIIINP were measured prior to laparoscopic exploration. Liver biopsy was performed for all patients. Liver fibrosis was staged on a five-point scale (F0-F4) according to the METAVIR scoring system. The correlation between serum markers and liver fibrosis stage was assessed. A receiver operator characteristic analysis was performed to determine the accuracy of serum markers for predicting the liver fibrosis stage. Results: Serum PIIINP and HA were positively correlated with liver fibrosis stage (r = 0.622, P < 0.001, and r = 0.41, P < 0.001, respectively). There was no significant correlation between serum LN and liver fibrosis stage (P > 0.05). Serum aspartate aminotransferase, total bilirubin, direct bilirubin, and PIIINP were independently correlated with the fibrosis stage on multivariate ordinal regression analysis. Receiver operating curve (ROC) analysis showed that serum PIIINP was the most effective for the diagnosis of fibrosis grade. The area under the ROC curves (AUROCs) for serum PIIINP for diagnosing fibrosis stages ≥F1, ≥F2, ≥F3, and F4 (cirrhosis) were 0.843, 0.789, 0.82, and 0.891, respectively. The cut-off serum PIIINP value for predicting fibrosis stage ≥F1 was 242.3 ng/mL, with 73.8% sensitivity and 90% specificity. The cut-off value for predicting cirrhosis was 698.7 ng/mL, with 75% sensitivity and 96% specificity. Conclusion: Serum PIIINP is a promising biomarker for predicting liver fibrosis stage, especially cirrhosis. Its assessment is a simple and non-invasive diagnostic method for liver fibrosis in infants with cholestasis.

Abstract
Aim: This study investigates the fall in total serum bilirubin levels within 1 week after surgery, as a marker to predict early outcome in biliary atresia (BA) patients post-Kasai portoenterostomy (KP). Methods: The ratio of total serum bilirubin levels at the 7th postoperative day to the preoperative level (TB7/TB0) in patients undergoing KP was calculated (January 2011–July 2015). Patients were stratified after 3-months follow-up into outcome groups depending on the clinical clearance of jaundice and TB7/TB0 ratio was correlated to outcome and liver histopathological changes in these groups. Results: Sixty-one patients (M:F = 44:17), median age 75 days were included. At the end of 3 months, 27 (44.39%) were anicteric while 26 (42.6%) were still clinically jaundiced. Patients with a higher median value of TB7/TB0, that is, 0.856 were more likely to have jaundice at the end of 3 months as compared to patients with a lower median value of 0.615 (P < 0.0001). A cutoff TB7/TB0 ratio >0.723 predicted the KP outcome with 84.6% sensitivity and 81.5% specificity. The difference in TB7/TB0 ratio between patients with varying severity of liver histopathological changes was also significant, namely, cholestasis (P = 0.01), hepatocellular damage (P = 0.03), portal inflammation (P = 0.04), and portal fibrosis (P = 0.02). Conclusions: The rapidity of fall in the total serum bilirubin levels within 1 week post-KP was able to predict the likely outcome in BA patients.

Abstract
Kasai hepato-portoenterostomy (HPE) is the most widely used surgical technique to restore bile flow in biliary atresia (BA). We aimed to review literature on HPE substitutes and additions to Kasai especially in advanced BA (ABA). A PubMed search was done for surgical procedures apart from or along with Kasai HPE for BA. Additional procedures to prevent cholangitis were also reviewed. Procedures and outcome were analysed. Alternative procedures done by the authors have also been described briefly. Results have been compiled in this review article. In ABA, with portal hypertension and liver cirrhosis, Kasai HPE is associated with poor outcome, increased morbidity, and even mortality. Most require liver transplant (LT). Some alternatives to HPE include exploration at porta hepatis to assess the bile flow yet avoid the major surgery (HPE) as a bridge to LT. Conduit diversion may help to combat cholangitis resistant to steroid therapy. Stoma formation is not preferred in cases listed for LT due to high risk of bleeding. Hepatocyte infusion, stem cell therapy, and synthetic liver are the future options to meet the challenges in BA. Various alternative procedures may become handy in the future especially in ABA.

Abstract
The liver biopsy guides diagnostic investigation and therapy in infants with undiagnosed cholestasis. Histologic features in the liver may also have prognostic value in the patient with biliary atresia (BA). We assessed the relative value of histologic features in 227 liver needle biopsies in discriminating between BA and other cholestatic disorders in infants enrolled in a prospective Childhood Liver Disease Research Network (ChiLDReN) cohort study by correlating histology with clinical findings in infants with and without BA. In addition, we reviewed 316 liver biopsies from clinically proven BA cases and correlated histologic features with total serum bilirubin 6 months after hepatoportoenterostomy (the Kasai procedure, HPE) and transplant-free survival up to 6 years. Review pathologists were blinded to clinical information except age. Semiquantitative scoring of 26 discrete histologic features was based on consensus. Bile plugs in portal bile ducts/ductules, moderate to marked ductular reaction, and portal stromal edema had the largest odds ratio for predicting BA versus non-BA by logistic regression analysis. The diagnostic accuracy of the needle biopsy was estimated to be 90.1% (95% confidence interval [CI]: 85.2%, 94.9%), whereas sensitivity and specificity for a diagnosis of BA are 88.4% (95% CI: 81.4, 93.5) and 92.7% (95% CI: 84.8, 97.3), respectively. No histologic features were associated with an elevated serum bilirubin 6 months after HPE, although it (an elevated serum bilirubin) was associated with an older age at HPE. Higher stages of fibrosis, a ductal plate configuration, moderate to marked bile duct injury, an older age at HPE, and an elevated international normalized ratio were independently associated with a higher risk of transplantation.

Abstract
BACKGROUND/AIMS The basic problem in diagnosis of neonatal cholestasis (NC) is to differentiate biliary atresia (BA) from other non-obstructive disorders. Because if bile flow cannot be provided by surgery, BA leads to cirrhosis and death within the first year of life. The aim of the present study is to determine histopathological features that may help to differentiate BA from neonatal hepatitis (NH). MATERIAL AND METHODS This retrospective study was carried out on 105 liver biopsy specimens of 74 infants with NC who were diagnosed between 2003 and 2012. RESULTS The mean age was 76.5 ± 40.64 days. The most valuable biopsy findings for the discrimination between NH and BA, in decreasing order of importance, were ductular proliferation (p < 0.001), cholestasis in neoductuli (p < 0.001), fibrosis (p = 0.002), and extramedullar hematopoiesis (p = 0.02). While Kasai operations were performed in 19 cases, liver transplantation was performed in 10 cases. Survival rate among the death cases with BA was longer than the survival time of the death cases with NH (p = 0.023). Currently more children live with a close to normal quality of life with portoenterostomy and/or liver transplantation. On the contrary, NH can be more fatal with associated disorders such as growth retardation, specific infections, respiratory distress, and metabolic or endocrine diseases.

Abstract
PURPOSE To evaluate the role of bone marrow-derived mononuclear cells (BMC) in rat bile duct ligation (BDL) model. METHODS Wistar rats were categorized into four Groups A-D. Normal liver biopsy was taken from Group A. BDL model was created in Groups B and C (15 each). Normal saline and BMC were injected through portal vein (PV) in Groups B and C, respectively. In Group D (healthy rat), only BMC were infused through PV. Groups B and C were compared for body weight, liver functions, survival, and histopathological changes. RESULTS Serum bilirubin was lower in Group C at day 6 (p = 0.0010). Median survival time was 5 (4, 6) and 13 (9, 17) days in Groups B and C (p = 0.0147), respectively. Portal edema (p = 0.013) and portal inflammation (p = 0.025) were less in Group C vs Group B. On post hoc subgroup analysis of rats surviving 8-26 days, portal inflammation (p = 0.004), bile duct proliferation (p = 0.016) and portal fibrosis (p = 0.038) were less in Group C vs Group B. Hepatocyte regeneration was found in four rats in Group C. CD34-positive cells were prominent in sinusoids and portal tracts in the BDL rat model. CONCLUSIONS BMC have shown to delay fibrosis, facilitate hepatocyte regeneration and improve survival in an experimental BDL model, with potential clinical implication in obstructive cholangiopathy.

Abstract
BACKGROUND In liver transplantation (LT) for adult biliary atresia (BA), we often encounter a cirrhotic deformation of the native liver. We aimed to investigate a morphological study of the removed livers and the patient's clinical status. METHODS We examined 8 BA patients who had undergone LT in adulthood at our hospital. The presence of hypertrophic or atrophic areas of the removed liver was recorded macroscopically. We graded the microscopic findings in the porta hepatis area, a hypertrophic area, and an atrophic area, respectively. Moreover, we investigated the relationship between these morphological findings and the pre-transplant clinical status (MELD score). RESULTS Macroscopically, a hypertrophic area existed in central liver in all cases (8/8 cases), while an atrophic area was existed in peripheral liver (7/8 cases). Microscopically, an atrophic area was the most severely impaired, while the porta hepatis and hypertrophic area were relatively intact. The pathological score in a compensatory hypertrophic area was strongly correlated with the MELD score. CONCLUSIONS This study suggests that the partial shrinking is not uncommon in BA cirrhotic liver. It may be due to the imbalance of bile drainage by the different segment. The patient's pre-transplant status depends on the compensatory hypertrophic liver.

Abstract
Biliary atresia is an infantile destructive inflammatory cholangiopathy that causes obliteration of both intrahepatic and extrahepatic bile ducts and eventually liver cirrhosis. So far, the exact etiology and pathogenesis of biliary atresia remain unclear, and possible etiologies include congenital and genetic factors, infection, inflammation, immune reaction, maternal factors, and vascular factors. Immunoinflammatory theory has been accepted by most researchers, which is supported by liver pathological changes. This review focuses on the recent progress in understanding pathogenesis and liver pathology in biliary atresia.

Abstract
CONTEXT Biliary atresia is an inflammatory cholangiopathy of infancy that results in progressive fibrosis and obliteration of bile ducts and represents the main indication for liver transplant in young children. In spite of extensive investigation, its etiology has remained poorly understood. Timely surgical intervention (Kasai procedure) may result in significant benefit to these patients and represents the final goal of an accurate diagnostic evaluation. OBJECTIVE To present an overview of biliary atresia, including clinical and surgical approaches to this disease, with emphasis on the histopathologic evaluation. DATA SOURCES Review of relevant literature indexed in PubMed (US National Library of Medicine). CONCLUSION A well-coordinated multidisciplinary approach is required in the assessment of suspected cases of biliary atresia. Pathologic examination of biopsy specimens is an integral part of the diagnostic algorithm and, therefore, plays a pivotal role in the diagnostic evaluation of this disease.
