Bile duct damage with inflammatory reaction. Cirrhosis and hepatocellular carcinoma (HCC), end stages of all chronic liver diseases, are characterized by expansion of small immature cholangiocytes – a mechanism named ductular reaction (DR). Thus, the following histological features were considered for the analysis: steatosis, hepatocellular damage, neutrophilic infiltration, ductular reaction, intraparenchymal cholestasis, and iron deposits. Histopathologically, cirrhosis is characterized by remodeling of the vascular architecture with septal formation and nodular groups of regenerating hepatocytes. Extensive bile ductular reactions (DRs) accompany many cholestatic liver diseases such as primary biliary cholangitis and primary sclerosing cholangitis (PSC) as well as parenchymal liver cell diseases such as alcoholic liver disease, non‐alcoholic steatohepatitis and HCV and HBV infections. Gut , 65 (4). . AKA cardiac cirrhosis - a term used by clinicians. Ductular reaction (DR) is characterized by the proliferation of reactive bile ducts induced by liver injuries. Ductular reaction (DR) is a reactive lesion at the portal tract interface comprising increased bile ductules with an accompanying complex of stromal and inflammatory cells. However, both the up and downregulation of autophagy have been implicated in fibrogenesis. Our previous studies have shown that autophagy mediates the link between ductular reaction (DR) and liver cirrhosis. Ductular reactions (DRs) are a mixed tissue reaction at the interface of portal tract or septal stroma and the hepatic parenchyma. PFIC3: Presentation in late infancy with rapid progression to biliary cirrhosis. DR cells are believed to be progenitors able to differentiate in cholangiocytes or in hepatocytes. N2 - Cystic fibrosis liver disease (CFLD) in children causes progressive fibrosis leading to biliary cirrhosis, however its cause(s) and early pathogenesis are unclear. Scoring system for ductular reaction was based on Chen et al. Identification of Pc (as a marker of canonical Hh signaling) in human cirrhosis was predominantly confined to the ductular reaction and LPCs. And from there, it may spread to the central acinar area and even reach an adjacent portal field to form a porto-portal septum. hepatic cirrhosis miscellaneous. Pleiotrophin regulates the ductular reaction by controlling the migration of cells in liver progenitor niches. A case of chronic hepatitis showing (a) single scattered CK19-positive cells in the lobule (arrow) (×100). Furthermore, ductular reaction was accompanied by a progressive increase in the arterial supply but a loss of portal blood supply. Identification of Pc (as a marker of canonical Hh signaling) in human cirrhosis was predominantly confined to the ductular reaction and LPCs. This process results in biliary fibrosis and subsequent liver cirrhosis. Biliary cirrhosis often demonstrates a marked ductular reaction along with patchy loss of bile ducts in the portal tracts and mild inflammation. • Second is biliary piecemeal necrosis, which is marked by a striking ductular reaction, sometimes referred to as ductular proliferation, and accompanied by edema, neutrophil infiltration, periductular fibrosis, and necrotic hepatocytes, the latter associated with cholestasis. This case of TPN-induced cirrhosis shows damaged hepatocytes with steatosis and inspissated bile. Reportedly, the patient had a positive antimitochondrial antibody. Ductular reaction was a common finding (55%) in patients with central zone arteries. The role of ductular reaction (DR) in hepatocellular carcinoma (HCC) remains to be elucidated. In other chronic liver diseases it has been shown that a ductular reaction (DR) appears early, correlates with fibrosis progression, and is a consequence of activation of an alternative pathway of hepatocyte replication. Longitudinal analysis of CDAA with 60% fat (HF-CDAA) feeding revealed pronounced ductular reaction and perisinusoidal bridging fibrosis, with a sevenfold increase of hepatic collagen at week 12, which showed limited spontaneous reversibility. Am J Physiol Gastrointest Liver Physiol. Primary biliary cirrhosis (PBC) is characterized by antimitochondrial autoantibodies (AMAs) in patients' sera and histologically by chronic nonsuppurative destructive cholangitis in small bile ducts, eventually followed by extensive bile duct loss and biliary cirrhosis. In the second family, 1 patient died awaiting transplantation and the other patient died at age 5 weeks from complications of an aortic thrombus. Ductular reaction, observed in 25 of 35 cases (71%) using conventional histology and in 30 of 32 cases (94%) using immunohistochemistry, was correlated with portal and lobular inflammation, interface hepatitis and centrilobular necrosis as well as bile duct injury and fibrosis. Children with biliary atresia develop biliary cirrhosis rapidly; with progressive disability. 2 Ductular reactions can occur in many types of disease, and the morphology does not always indicate the precise cause. Comparison of murine steatohepatitis models identifies a dietary intervention with robust fibrosis, ductular reaction, and rapid progression to cirrhosis and cancer. Cases of hepatitis, cirrhosis and HCC stained for CK19. In order to avoid high complexity we additionally combined score 1 and 2 from Chen et al. ductular reaction) Common Less common (except in progressive disease – associated with fibrosis) Fibrosis Mild (collapse, reversible) Variable (may progress to cirrhosis) 2 Acute Lobular Hepatitis Histological Findings in Liver Parenchyma 1. Bile ductular proliferations with a variety of chronic biliary tract diseases, including primary biliary cirrhosis and biliary atresia, 2 tend to be CD56-positive (eFig. Fibrosis around dilated bile ducts, “typical” and “atypical” ductular reaction and an inflammatory infiltrate composed of lymphocytes and pigmented macrophages, with iron deposits and lipofuscin, were found. STAGE II - PERIPORTAL. The relationship between the extent of fibrosis-ductular reaction, proliferative activity of hepatocytes and ductular reaction were studied sequentially in experimental hepatic fibrosis models.Liver fibrosis/cirrhosis was induced in wild type and TGFβ overproducing transgenic mice by carbon tetrachloride and thioacetamide administration. This is similar to the lesion found in autoimmune hepatitis (AIH). The concept of dissecting DRs explains the micronodular pattern of advanced biliary and alcoholic cirrhosis. Ductular reaction … The patient currently has an elevated alkaline phosphatase (184). The rats that did not present dilatation in the diameter of the bile duct, absence of ductular reaction (i.e., increased number of ductules and ducts), fibrosis in the liver tissue, and those that died during the course of the experiment were excluded and replaced by other animals. Background and objective Persistent hepatic progenitor cells (HPC) activation resulting in ductular reaction (DR) is responsible for pathologic liver repair in cholangiopathies. The ductular cell reaction, or ductular cell proliferation together with the inflammatory cell infiltration, 7 has been linked to hepatic fibrogenesis and cirrhosis. Recent studies disclosed that autophagy facilitates the process of senescence. Morphological analysis demonstrated that nodularity, fibrous stroma, dystrophic blood vessels, and ductular reaction were more common in focal nodular hyperplasia, while telangiectasia, hemorrhage, and steatosis were more common in inflammatory hepatocellular adenoma, but there was frequent overlap of morphological features. In addition to steatosis and steatohepatitis, long-term total parenteral nutrition (TPN) may result in cholestasis, hepatocellular damage, ductular reaction, fibrosis, and cirrhosis. b. At that time, it was a stage 1 lesion. Marked hepatocyte swelling and regenerating cholestatic rosettes (hepatocyte “pseudoglands”) may be present in the hepatic lobules ( Fig. When the damage is chronic, regeneration goes awry, impairing liver function and causing cirrhosis. There is no significant steatosis (less than 5%). micronodular cirrhosis: [ sĭ-ro´sis ] a liver disease (actually a group of chronic diseases) characterized by loss of the normal microscopic lobular architecture and regenerative replacement of necrotic parenchymal tissue with fibrous bands of connective tissue that eventually constrict and partition the organ into irregular nodules. – Cirrhosis (see comment) COMMENT: Histologic sections of the liver biopsy show extensive fibrosis with regenerative nodule formation, consistent with cirrhosis. Original Article Immunohistochemical study for the origin of ductular reaction in chronic liver disease . Although N-CAM is useful in differentiating CLC from classical well-differentiated ICCs, which commonly do not express this marker, BDA and ductular reaction [53,54] are also N … PMID: 31630534. Also, HPC/DR expansion correlates with fibrosis in several chronic liver diseases, including steatohepatitis. nephronophthisis-associated hepatic disease; hepatic Ellis-van Creveld disease; Elementary lesions associated: bile plugs ductular dilatation neutrophilic infiltration. DR is pathologically recognized as bile duct hyperplasia and is commonly observed in biliary disorders. Biochemically, the cirrhotic liver functions less efficiently than the normal liver. In contrast, GLI2 … ... ductular reaction, fibrosis and may extravasate into the periportal liver parenchyma thus disrucpting the periportal limiting plate of hepatocytes. In fact, this study showed that the degree of bile ductular reaction was positively correlated with the degree of portal inflammation in addition to fibrosis. toxicity, and ultimately fibrosis progressing to cirrhosis. In response to injury, sophisticated mechanisms are engaged to repair and regenerate the damaged liver, preventing its failure. Micronodular cirrhosis and fibrosis were evident at later stages. A prom-inent response to biliary obstruction is ductular reaction, which occurs at the interphase of the portal and parenchymal compart - ments and is also observed in virtually all forms of human liver diseases (3). Given that cellular senescence is involved in the pathophysiology of ductular reaction (DR) in primary biliary cirrhosis (PBC), we examined an involvement of autophagy in DRs in PBC and control livers. In PFIC3 (Figure 5), there is bile ductular proliferation, inflammatory infiltrate and biliary fibrosis with mild expansion of portal tracts due to a ductular reaction. K18 is produced in hepatocytes while K19, the most widely used ductular reaction (DR) marker, is found in cholangiocytes and hepatic progenitor cells. Some cases demonstrate heterogeneity of the 3 features throughout the tissue. Vanished bile ducts, portal and periportal inflammation and ductular proliferation. Liver biopsies showed intralobular cholestasis, diffuse giant cell transformation, ballooning hepatocytes, and ductular reaction. 10.1136/gutjnl-2014-308176 . N2 - Patients with Alagille syndrome (AGS), a genetic disorder of Notch signaling, suffer from severe ductopenia and cholestasis, but progression to biliary cirrhosis is rare. View 0 peer reviews of Ductular Reaction Cells Display an Inflammatory Profile and Recruit Neutrophils in Alcoholic Hepatitis on Publons Download Web of Science™ My Research Assistant : Bring the power of the Web of Science to your mobile device, wherever inspiration strikes. Ductular reaction: A reactive process that consists of a mixture of ductular proliferation, inflammation, and stromal cells along the limiting plate. cirrhosis. We adapted the scoring of the latter study by including two different cirrhosis scores: 3 = cirrhosis with few and 4 = cirrhosis with many DR (see Table 1). Comparison of murine steatohepatitis models identifies a dietary intervention with robust fibrosis, ductular reaction and rapid progression to cirrhosis, cancer Guangyan Wei, Ping An, Kahini Vaid, Imad Nasser, Pinzhu Huang, Li Tan, Shuangshuang Zhao, Detlef Schuppan, Yury Popov 1–5 These markers include biliary antigens (cytokeratin [CK]7, CK19, and OV-6), hepatocyte antigens … Gross "Nutmeg" liver - yellow spotted appearance. Differential diagnosis: must be distinguished from interlobular bile ducts FIGURE 8.3 Ductular reaction may be part of tumor-associated changes in adjacent parenchyma due to localized bile duct obstruction. Knock-in mice expressing a CCN1 mutant that is unable to bind α v β 5 /α v β 3 were impaired in ductular reaction, leading to massive hepatic necrosis and mortality after bile duct ligation (BDL), whereas treatment of these mice with soluble JAG1 rescued ductular reaction and … There was no biopsy evidence suggestive of sclerosing cholangitis such as a concentric “onion like” fibrosis nor fibro-obliterative scar of … The regenerative nodules in biliary cirrhosis tend to be jigsaw puzzle-shaped as opposed to the rounded contours in nonbiliary causes of cirrhosis. DR is pathologically recognized as bile duct hyperplasia and is commonly observed in biliary disorders. STAGE III - FIBROSIS. Due to the high prevalence (> 95%) of cirrhosis in our patient population, we decided not to take fibrosis into consideration. However, occasionally there are cases in which only 1 or 2 of the features are present, making the scoring difficult. Whether the subsequent fibrogenic response is regulated by increased autophagy in DR remains unclear. Historically, ... Cirrhosis is a diffuse fibrosis of the liver leading to parenchymal nodularity. It can also be identified in various liver … Data represent mean + SEM of 4–8 mice from 3 independent experiments. Ductular reactions (DRs) in DP configuration are the predominant type of progenitor cell reaction in fulminant necro-inflammatory liver disease, when lack of sufficient parenchymal regeneration results in liver failure. (A) Ductular reaction grade, (B) fibrosis score and (C) whole liver Col1a1 expression in livers from water- and 12-week TAA-treated control and LysM-Wls male mice. In contrast, the ductular reaction in acute obstruction tends to be CD56-negative, EMA-positive, and CD10-negative. It should lead to rebiopsy. The morphologic features may mimic those of bile duct obstruction. FIGURE 8.4 In biliary cirrhosis, ductular reaction is diffusely embedded in the portal tracts and fibrous bands. case 102: part 1: allograft liver, needle biopsy - a. central lobular hepatocellular swelling, mild ductular reaction, and moderate deposition of ceroid pigment/iron in kupffer cells and macrophages; consistent with ongoing recovery from moderate ischemic/preservation injury (see microscopic description). 2020 01 01; 318(1):G174-G188. 46.2 ). • A patient with chronic hepatitis C may develop fibrosing cholestatic hepatitis, in which severe exacerbation of intrahepatocellular hepatitis C virus (HCV) growth results in defective bile secretion and marked cholestasis, along with a prominent ductular reaction. D: Proliferation of ducts associated with periductal fibrosis. Biological values The lysosomal degradation pathway, or autophagy, plays a fundamental role in cellular, tissue, and organismal homeostasis. ... and portal inflammation, fibrosis and bile ductular reaction. In cirrhosis following a variety of chronic disease processes, including viral and autoimmune hepatitides, bile duct destructive diseases, such as primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC), and toxic injury from chronic alcohol use, a similar ductular reaction takes place (4, 17-21). In this study, we tried to uncover possible effect by correlating peritumoral DR in a necroinflammatory microenvironment with postoperative prognosis in HCC. Changes to viability and gene expression in LPCs in vitro were assessed following GLI inhibition. In contrast, GLI2 was expressed in multiple cell populations including Pc-ve endothelium, hepatocytes, and leukocytes. The expression of peritumoral DR/CK19 by immunohistochemistry, necroinflammation and fibrosis were assessed from … A correlation between dysregulated autophagy and liver fibrosis (including end-stage disease, cirrhosis) is well-established. The liver is one of the major metabolic organs in the body, susceptible to injury caused by various factors. It was found in this study that small spindle-like CK7-positive, CK19-negative cells, were increased in the hepatic parenchyma in advanced stages of NAFLD. Keratins (Ks) represent tissue-specific proteins. Cirrhosis is finally established. Prominent “ductular reaction” resembling biliary obstruction Cholestasis Hepatocyte feathery degeneration with lobular disarray Sinusoidal/pericellular fibrosis Criteria for Diagnosis At least ¾ of the characteristic histological features Timeframe of >1 month after liver transplantation Prognosis (CK19, ×100). pp. The fibrous septae show a bile ductular reaction and variable chronic inflammatory infiltrate composed of lymphocytes and plasma cells. In the setting of cirrhosis, these hepatocellular nodules pose an increasingly frequent differential diagnostic problem, although few pathologists have had consistent experience with them. Comparison of murine steatohepatitis models identifies a dietary intervention with robust fibrosis, ductular reaction and rapid progression to cirrhosis, cancer Guangyan Wei, Ping An, Kahini Vaid, Imad Nasser, Pinzhu Huang, Li Tan, Shuangshuang Zhao, Detlef Schuppan, Yury Popov C: Proliferation of ducts and ductules simulates changes of mechanical obstruction, Cytokeratin stain. B: Prominent ductular reaction at portal margin. Canalicular cholestasis is present in centrilobular areas, and biliary/micro nodular cirrhosis supervenes with … Single-cell sequencing revealed heterogeneity within BECs and highlighted distinct subsets with increased proliferate capacity, hepatocyte markers or expression of pro-inflammatory genes . The patient's previous liver biopsy (DPS-10-4275) showed changes which favored primary biliary cirrhosis. Ductular reaction is a complex, dynamic and nonspecific reaction to liver injury and disease (acute and chronic) characterized by a ductular phenotype, possibly but not necessarily of ductular origin, at the portal - parenchymal interface. (c) A case of HCC showing negativity for CK19 in tumor cells. Nomenclature of the finer branches of the biliary tree: Canals, ductules, and ductular reactions in human livers Cirrhotic nodules are surrounded by a rim of CK 7/CK19-positive biliary cells termed ductular reaction. (b) A case of cirrhosis showing a higher grade of CK19-positive ductular reaction and individual positive cells in the lobule (arrow). 1 From the standpoint of marker analysis, ductular cells in DR are reportedly heterogeneous in their phenotypes. For patients with cirrhosis treated with DAA, ... For example, thick fibrous septae are likely to demonstrate inflammation and bile ductular reaction. The surviving parenchyma persisted with a jigsaw pattern characteristic of biliary cirrhosis. The lesion is conventionally divided into four stages: STAGE I - FLORID. 2. demonstrated biliary cirrhosis with moderate portal in-flammation, ductular reaction, minimal loss of small bile ducts and chronic cholestasis. 11.2), EMA-negative, and CD10-negative. The development of portal fibrosis following the iron loading of hepatocytes is the first stage of fibrogenesis in hereditary hemochromatosis. FIGURE 2. 683-692. K18-based serum fragments are commonly used liver disease predictors, while K19-based serum fragments detected through CYFRA21-1 are established tumor but not liver disease … We hypothesised that a bile acid-induced Ductular Reaction (DR) drives fibrogenesis. Antiductular antibody was found most frequently in primary biliary cirrhosis (75%), viral hepatitis (67%), and postnecrotic cirrhosis (47%), and the incidence roughly reflected the extent and severity of the bile ductular reaction. 32, 33, 34 Therefore, ... S100B protein is expressed in normal bile duct epithelial cells and is highly upregulated with bile duct proliferation (ductular reaction) during liver fibrosis by BDL, which correlates well with the transcript levels of other markers of fibrosis. BECs can expand [4] during DR or transdifferentiate into hepatocytes to support liver regeneration [2, 3]. Ductular reaction: bile ductular proliferation progressive with time which mean the severity of the disease increases with time Cholestatic because it targets the bile ducts, leading to obstruction, leading to elevated cholesterol level and hyperbilirubinemia and bile salt deposition ductular reaction (DR) [2]. Generally, it does not satisfy pathologic criteria for cirrhosis. Biliary cirrhosis and, with time, micronodular cirrhosis supervene with a biliary halo around cirrhotic nodules, ductular reaction, and bile plugs. Increased ductular reaction and fibrosis in male LysM-Wls mice compared to littermate controls. Instead, in biliary atresia (BA) severe cholestasis is associated with a pronounced "ductular reaction" and rapid progression to biliary cirrhosis. By using dual-immunofluorescence staining, we demonstrated that increased LC3B was located mainly in the cytokeratin 19–labeled ductular reaction (DR) in human cirrhotic livers and in an experimental cirrhosis induced by 2-acetylaminofluorene (AAF) with carbon tetrachloride (CCl 4), indicating a conserved response to chronic liver damage. into score 1 in the current study. The ductular reaction is one of the key injury patterns in the liver. The finding of a prominent bile ductular reaction associated with neutrophils (termed cholangiolitis) in the portal tracts may contribute to confusion with biliary obstruction. Hepatic expression of genes related to ductular reaction in patients with chronic liver disease (cohort i). CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Patients with Alagille syndrome (AGS), a genetic disor-der of Notch signaling, suffer from severe ductopenia and cholestasis, but progression to biliary cirrhosis is rare. Sinusoidal dilatation is often also observed. It can also be identified in various liver … Cirrhosis is the final stage of a variety of chronic diseases involving the liver. HSCs/myofibroblasts (>99%) expressed GLI2, with only 1.92% displaying Pc. K18-based serum fragments are commonly used liver disease predictors, while K19-based serum fragments detected through CYFRA21-1 are established tumor but not liver disease markers yet. Ductular reaction (DR) is characterized by the proliferation of reactive bile ducts induced by liver injuries. Objective The ductular reaction (DR) involves mobilisation of reactive-appearing duct-like cells (RDC) along canals of Hering, and myofibroblastic (MF) differentiation of hepatic stellate cells (HSC) in the space of Disse. K18 is produced in hepatocytes while K19, the most widely used ductular reaction (DR) marker, is found in cholangiocytes and hepatic progenitor cells. Cirrhosis is a premalignant condition leading to hepatocellular carcinoma. Cholestasis is common. Ductular reaction may be present Patients systemically ill, often with sepsis and/or bacteremia Often jaundiced Micro: Classically, Ductular cholestasis (“cholangitis lenta”) However, this is challenged by some as this seems to be common in any condition with cholestasis (including during the hepatic dysfunction seen with sepsis) The damage will lead to cirrhosis.
