Correlation of APRI Index with Metavir Index in Children with Neonatal Cholestasis Without Biliary Atresia

Combi-Elasto Evaluation of the Degree of Liver Fibrosis in Children with Cholestatic Liver Disease

Cholestatic liver disease is a common liver disease in infants and young children. Liver fibrosis is a key factor affecting the prognosis, and liver transplantation is the only treatment option for liver cirrhosis. This study aimed to explore the efficacy of Combi-elasto for diagnosing liver fibrosis in children affected by cholestatic liver disease. A total of 64 children with S1-S4-grade liver fibrosis were enrolled. The general data, routine ultrasound, Combi-elasto, aspartate aminotransferase-to-platelet ratio index (APRI) and Fibrosis-4 (FIB-4) score were compared among children with different grades of liver fibrosis, and the efficacy of the above indexes for evaluating the degree of liver fibrosis was reported. There were remarkable differences in liver size, liver echogenicity, Young's modulus (E), fibrosis index (FI), activity index (AI) and FIB-4 score among the groups (all p < 0.05). E and liver echogenicity were the independent impact factors of liver fibrosis. The areas under the curve of E, APRI, FIB-4 score and the combined model (E+ liver echogenicity) in the evaluation of liver fibrosis were 0.84, 0.61, 0.66 and 0.90, respectively. Ultimately, we concluded that CE is an effective method to evaluate liver fibrosis in children with cholestatic liver disease.

Evaluating the non-invasive tools for assessment of liver fibrosis in children with intrahepatic cholestasis prior to partial biliary diversion: tertiary-center experience

Background

The liver biopsy is an essential element of evaluating progression of liver disease in children with Progressive Familial Intrahepatic Cholestasis (PFIC) and Allagille Syndrome (AGS). Several noninvasive techniques, including radiological imaging and blood biomarkers assay, can be used to evaluate liver stiffness.

Objectives

To identify whether liver Transient elastography (FibroScan) and AST/PLT Ratio Index (APRI) could be reliable tools to assess the degree of fibrosis prior to partial biliary diversion (PBD).

Methods

A prospective cohort in which all patients with PFIC and AGS who underwent PBD from July 2019 to July 2021 were included. Preoperative liver functions, pelvic-abdominal ultrasonography and FibroScan assessments were performed while intraoperative liver biopsy was obtained.

Results

Eight patients with chronic cholestatic liver disease who were candidates for PBD due to intractable pruritus were enrolled, including PFIC (n = 6; 75%), and AGS (n = 2; 25%). The liver FibroScan results were similar to the liver biopsy histopathological assessment in 87.5% of cases. APRI ranged from 0.1 to 3.2 (median = 1.2). In four cases (50%), APRI was consistent with histological evaluation of liver samples. The FibroScan results were in concordance with APRI results in three patients (37.5%).

Conclusion

The current cohort demonstrated that fibroScan was consistent with histopathology in 87.5% of patients, highlighting its value in determining the degree of liver fibrosis prior to surgery, whereas the APRI was only consistent with histopathology in half of cases.

Risk Prediction Scoring System to Predict the Postsurgical Outcomes of Biliary Atresia

Aim

To find out association between liver function, liver histopathology and outcomes of biliary atresia (BA) following Kasai Portoenterostomy (KPE).

Materials and Methods

This is a retrospective study of children who underwent KPE at a single institute by single surgeon. The patient records analyzed and data of complete blood counts, liver function tests, coagulation profile and histopathology reports collected. The outcomes recorded as alive and jaundice free, alive but jaundiced, and deceased. Statistical analysis done using SPSS 23.

Observations

Total of 148 children operated during January 2000 to December 2018. Of these, 26 matched inclusion criteria. The parameters assessed were percentage of direct bilirubin, ratios of Aspartate transaminase (AST) to Alanine transaminase (ALT); Gamma glutamyl transferase (GGT) to AST; GGT to ALT and Aspartate transaminase to platelet ratio index (APRi). Among histopathology reports, fibrosis grade and bile ductular size noted. Among 26, 16 alive and ten are deceased. Among 16 alive, all are jaundice free. Of the parameters, ratio of AST to ALT, APRi and grade of fibrosis found statistically significant and further analysis showed if AST to ALT ratio < 2.1, APRi < 1.8 and grade of fibrosis < four, irrespective of age at surgery, had 96.2 % probability of successful KPE. Based on these observations, a scoring system and risk prediction model constructed based on Receiver operating characteristic (ROC) curves which are first in BA management.

Results and Conclusion

Although numbers are sufficient for statistical analysis, we further intend to validate the scoring system in a prospective trial. BA children can be subjected to risk prediction model and KPE performed in those who have a score less than seven and offered to those with score between eight and 16 out of 20.

Key Message

The scoring system and risk prediction model can guide in the management and post-operative follow up of children with biliary atresia.

A Liver Biopsy Validation Pilot Study of Shear Wave Elastography, APRI, FIB-4, and Novel Serum Biomarkers for Liver Fibrosis Staging in Children With Chronic Viral Hepatitis

As liver biopsy in children poses inherent risks, noninvasive measures of liver fibrosis are needed. This was a cross-sectional, liver biopsy validation pilot study of 16 participants evaluating the ability of shear wave elastography, aspartate transaminase to platelet ratio index (APRI), fibrosis index based on the 4 factors, and novel serum biomarkers to stage liver fibrosis in children with chronic hepatitis B or C. There was very high intrasegmental shear wave speed variation in our participants and little correlation with fibrosis. APRI and monocyte chemoattractant protein (MCP-1) were higher in fibrosis stage F2-3 versus F0-1 (P = .02, P = .06, respectively). Soluble Fas (sFas) was lower in F2-3 versus F0-1 (P = .046). A logistic regression analysis calculated by (APRI × MCP-1)/sFas demonstrated an area under the receiver operating characteristic curve of 0.92 (P < .001), suggesting that this combination can differentiate fibrosis stage F0-1 from F2-3 in children with chronic viral hepatitis.
