JHEP Rep 2024; 6:100901. [PMID: 38235169 PMCID: PMC10790098 DOI: 10.1016/j.jhepr.2023.100901] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/20/2023] [Revised: 08/03/2023] [Accepted: 08/24/2023] [Indexed: 01/19/2024] Open
Abstract
Background & Aims Long-term follow-up studies of paediatric onset autoimmune liver disease (AILD) are invaluable in helping better understand the clinical course of disease. In day-to-day practice clinicians struggle with disease definitions whilst patients and parents lack clear prognostic information. Methods The clinical progression of 159 patients with childhood onset AILD between June 1990 and December 2013 was reviewed, capturing data up to adulthood (ending May 2021). Results Presentation with autoimmune hepatitis (AIH) was dominant (n = 119); biliary presentations accounted for 25%. During follow up, biliary disease progression confirmed by cholangiography and/or liver histology was observed frequently: 19.8% (20/101) patients with childhood onset AIH type 1 (AIH-1) developed biliary features by adulthood and of these 50% phenotypically transitioned to primary sclerosing cholangitis (PSC); the remaining transitioned to an overlap disease phenotype. No patients with AIH type 2 developed biliary progression. Two-thirds of patients with overlap features (14/21) in childhood had phenotypically progressed to PSC by adulthood. Approximately 43% (6/14) of AIH-1 patients requiring a liver transplant in adulthood had explant evidence of biliary disease compared with 11% (1/9) in childhood, whereas 35.7% (5/14) of patients had histology diagnostic of PSC in their explant liver and 7.1% (1/14) had overlap features. All patients with biliary phenotypes (PSC, autoimmune sclerosing cholangitis, overlap) who required a transplant (n = 18) were found to have explant histology consistent with PSC. Twelve of 14 patients with biliary progression developed ulcerative colitis during follow-up with 92% progressing to PSC. Conclusions Three decades of follow-up demonstrated how children presenting with AILD had a significant risk of clinical transformation to PSC. Biliary progression was significantly associated with the development of inflammatory bowel disease. Impact and implications Childhood onset autoimmune liver disease remains very impactful for patients and families. Disease nomenclature can however be confusing. Long-term follow up studies as children become adults is important to help understand how and why disease behaves over time. Understanding more about the long-term course of childhood autoimmune liver disease will help patients, families and doctors striving to improve care and reduce poor clinical outcomes. We followed over 150 patients with childhood onset autoimmune liver diseases into adulthood. We found that amongst patients with classical autoimmune hepatitis, 1 in 5 developed biliary disease over time, mostly consisting of primary sclerosing cholangitis. This was associated with developing inflammatory bowel disease. Our study design was retrospective and has relevant limitations. Defining phenotypes of autoimmune liver diseases is difficult and there is insufficient consensus, especially between adult and childhood physicians. Our data confirms the critical importance of careful long-term follow-up of patients, including safe transition to adult care, as well as robustly demonstrates, using real-world data, how disease nature can change over time. Our study affirms the need for investment in prospective cohort studies.

Anthocyanins: Traditional Uses, Structural and Functional Variations, Approaches to Increase Yields and Products' Quality, Hepatoprotection, Liver Longevity, and Commercial Products. Int J Mol Sci 2022; 23:ijms23042149. [PMID: 35216263 PMCID: PMC8875224 DOI: 10.3390/ijms23042149] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2021] [Revised: 02/08/2022] [Accepted: 02/08/2022] [Indexed: 02/06/2023] Open
Abstract
Anthocyanins are water-soluble, colored compounds of the flavonoid class, abundantly found in the fruits, leaves, roots, and other parts of the plants. The fruit berries are prime sources and exhibit different colors. The anthocyanins utility as traditional medicament for liver protection and cure, and importance as strongest plants-based anti-oxidants have conferred these plants products different biological activities. These activities include anti-inflammation, liver protective, analgesic, and anti-cancers, which have provided the anthocyanins an immense commercial value, and has impelled their chemistry, biological activity, isolation, and quality investigations as prime focus. Methods in extraction and production of anthocyanin-based products have assumed vital economic importance. Different extraction techniques in aquatic solvents mixtures, eutectic solvents, and other chemically reactive extractions including low acid concentrations-based extractions have been developed. The prophylactic and curative therapy roles of the anthocyanins, together with no reported toxicity has offered much-needed impetus and economic benefits to these classes of compounds which are commercially available. Information retrieval from various search engines, including the PubMed®, ScienceDirect®, Scopus®, and Google Scholar®, were used in the review preparation. This imparted an outlook on the anthocyanins occurrence, roles in plants, isolation-extraction, structures, biosynthetic as well as semi- and total-synthetic pathways, product quality and yields enhancements, including uses as part of traditional medicines, and uses in liver disorders, prophylactic and therapeutic applications in liver protection and longevity, liver cancer and hepatocellular carcinoma. The review also highlights the integrated approach to yields maximizations to meet the regular demands of the anthocyanins products, also as part of the extract-rich preparations together with a listing of marketed products available for human consumption as nutraceuticals/food supplements.

The role of diffusion tensor imaging of the liver in children with autoimmune hepatitis. Pol J Radiol 2021; 86:e461-e467. [PMID: 34567291 PMCID: PMC8449556 DOI: 10.5114/pjr.2021.108171] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/01/2021] [Accepted: 04/15/2021] [Indexed: 12/04/2022] Open
Abstract
Purpose To evaluate the role of diffusion tensor imaging (DTI) of the liver in children with autoimmune hepatitis (AIH). Material and methods A prospective study was done on 42 children with AIH (30 girls and 12 boys, with a mean age of 13 years) and 20 age- and sex-matched healthy control children. They underwent DTI of the liver and laboratory tests. Liver biopsy was done for the patients. The mean diffusivity (MD) and fractional anisotropy (FA) of the liver were calculated and correlated with the pathological results. Results The mean MD and FA of the liver in children with AIH were 1.42 ± 0.06 × 10-3 mm2/s and 0.37 ± 0.11; and in the control children they were 1.55 ± 0.07 × 10-3 mm2/s and 0.25 ± 0.03, respectively. The MD and FA were significantly different in the children with AIH compared to the control children (p = 0.001). The cutoff MD and FA used to differentiate patients from controls were 1.50 × 10-3 mm2/s, 0.31 with AUC of 0.919 and 0.813, sensitivity of 97.6% and 66.7%, a specificity of 80% and 70%, an accuracy of 94.2% and 67.3%, PPV of 95.3 and 90.3, and NPV of 88.9 and 33.3, respectively. There was significantly lower MD and higher FA of the liver in children with AIH type I (n = 31) than type II (n = 11) (p = 0.001), and patients with (n = 9) and without (n = 33) overlap syndrome (p = 0.005). Conclusions We concluded that DTI parameters can help to diagnose AIH, detect its phenotyping, and give clues as to the presence of associated overlap syndrome.

Abstract
Background and Objectives Chronic liver disease (CLD) in children present a broad spectrum of symptoms. Limited resources in Paediatric Hepatology in developing countries like Pakistan present considerable challenges in investigating and treating children with chronic liver disease in a timely fashion. This study aimed to determine the spectrum and outcomes of CLD other than chronic hep B & C virus (HBV& HCV) liver disease in children. Methods This retrospective descriptive study was conducted at the Paediatric Gastroenterology and Hepatology Department, Pakistan Kidney and Liver Institute and Research Centre in Lahore, Pakistan. The duration of the study was from August 2019 to January 2020. A total of 162 children of CLD were seen during this period of time. Of 162 there were 130 children with chronic HBV & HCV who were excluded from this study. 32 children aged 15 years or younger with chronic liver disease were included. The referrals were received from primary and secondary health care centres in different parts of the country. The data were collected from hospital electronic medical records database and then incorporated into a spreadsheet for analysis. The statistical analysis was performed by applying t-test with p value determined. Results Of 32 children autoimmune hepatitis (n=11; 34.3%) was the most common cause for chronic liver disease referrals, followed by progressive familial intrahepatic cholestasis type-2, (n=7; 21.8%), post Kasai for biliary atresia, (n=4; 12.5%), glycogen storage disease type-1 (n=5; 15.6%), Wilson disease (n=3; 9.3%) and primary sclerosing cholangitis (n=2; 6.2%). The diagnosis was principally established with the assistance of liver ultrasound, liver biopsy, magnetic resonance cholangiopancreatography and genetic testing. Conclusion Autoimmune hepatitis was the most common chronic liver disease. Our systematic approach, in addition to an extensive workup, helped us to diagnose and then initiate an appropriate treatment, which resulted in a more optimal outcome. Prompt referrals to tertiary centres are recommended where resources and expertise are available to reduce patient morbidity and mortality.

Abstract
BACKGROUND Diagnosis of rare diseases possesses a great challenge in pediatric hepatology because expert knowledge in the field is extremely insufficient. The study aims to explore new findings and collect diagnostic experience from pediatric rare liver diseases. METHODS The large-sample case analysis study included pediatric patients who had liver-involved rare diseases. All cases underwent liver biopsy and/or gene sequencing. RESULTS A total of 1158 pediatric patients were identified. Liver-based genetic diseases were most frequent (737 cases), followed by liver damages involved in extrahepatic or systemic disorders (151 cases) and cryptogenic hepatobilliary abnormalities (123 cases). Of note, diagnoses of 16 patients were re-evaluated according to genetic results combined with clinical pointers. In addition, 101 patients who underwent gene sequencing remained undiagnosed. Of them, 55 had negative genetic findings, 30 harbored mutations that failed to meet their typically pathogenic condition, and 16 had detected variants that were inconsistent with clinical pointers. CONCLUSIONS As a study involving known largest number of children with rare hepatobiliary disorders, it allows us to accumulate information (especially new findings) on the etiology and diagnosis of these disorders. The results can help to improve the diagnostic quality in the population. IMPACT Liver-based genetic diseases were most frequent in clinical profiles of pediatric rare liver diseases. Some novel variants in cases with genetic diseases (for example, two variants of c.3638G>T and c.1435G>C in a patient with progressive familial intrahepatic cholestasis type 2) were identified. As a study involving known largest number of pediatric cases with rare hepatobiliary disorders, it allows us to accumulate information on the etiology and diagnosis of these disorders. The study can help to optimize the diagnostic process and significantly improve the diagnostic quality in the field of pediatric hepatology. Given that clinical variability often exists within rare genetic disease entities and not all rare disorders are genetic, clinicians should not over-depend on the genetic results in the diagnosis.

Abstract
BACKGROUND Little is known about the relationships between MRI splenic T1 relaxation measurements and other radiologic and clinical markers of chronic liver disease, including the presence of radiologic portal hypertension. OBJECTIVE To evaluate the relationships between MRI splenic T1 relaxation and other radiologic and clinical biomarkers of liver fibrosis, including the presence of radiologic portal hypertension, in children and young adults with autoimmune liver diseases (AILD). MATERIALS AND METHODS Research MRI examinations performed at 1.5 T from 63 AILD registry participants were identified. Spleen T1 and iron-corrected T1 (cT1) relaxation measurements, liver cT1, liver/spleen stiffness, splenic length percentile for age, and presence of radiologic portal hypertension were recorded, along with demographic and laboratory data. The Mann-Whitney U test was used to compare continuous data between groups; Spearman correlation was used to evaluate associations. Areas-under-the-receiver operating characteristic curve (AuROC) was used to assess diagnostic performance. RESULTS Mean age was 15.2 ± 4.1 years. Mean splenic T1 and cT1 values for the study population were 1158.0 ± 70.9 ms and 1436.0 ± 68.9 ms, respectively. Splenic T1 and cT1 values positively correlated with APRI and FIBROSIS-4 scores, splenic length percentile, liver cT1 values, and liver and spleen stiffnesses (p-values < 0.05). There was no significant relationship between splenic T1/cT1 and age (p-values > 0.05). Splenic T1 and cT1 values were higher in participants with vs. without radiologic portal hypertension (n = 18) (1213.4 ± 69.6 vs. 1135.4 ± 58.5 ms; p = 0.0001, and 1488.2 ± 64.8 vs. 1415.1 ± 59.1 ms; p = 0.0002). Splenic T1 and cT1 both demonstrated an AuROC of 0.81 for discriminating patients without and with portal hypertension (p-values < 0.0001). CONCLUSION Splenic T1 relaxation is associated with other radiologic and clinical biomarkers of liver fibrosis, including radiologic portal hypertension, in children and young adults with AILD.
