The histological grading of fibrosis in Budd-Chiari syndrome: A chronic liver disease, different from others.

Introduction: Budd-Chiari syndrome (BCS) is an uncommon disease caused by hepatic venous outflow obstruction. They can result in centrilobular fibrosis, nodular regenerative hyperplasia and cirrhosis. Assessing liver fibrosis is crucial for determining the stage of BCS, predicting disease progression and guiding treatment decisions.

Rejuvenating bone marrow hematopoietic reserve prevents regeneration failure and hepatic decompensation in animal model of cirrhosis.

Background And Aim: Bone marrow stem cells (BM-SCs) and their progeny play a central role in tissue repair and regeneration. In patients with chronic liver failure, bone marrow (BM) reserve is severally compromised and they showed marked defects in the resolution of injury and infection, leading to liver failure and the onset of decompensation. Whether BM failure is the cause or consequence of liver failure during cirrhosis is not known.

Clinical and Genomic Perspective of SARS CoV-2 Infection in Liver Disease Patients: A Single-Centre Retrospective Study.

The limited literature on the clinical course of COVID-19 among patients with underlying liver disease (LD) is available from India. The present study aimed to evaluate the clinical and mutational profile of SARS-CoV-2 among LD cases. This was a retrospective study including admitted LD cases in whom SARS-CoV-2 RT-PCR testing was performed.

Survivin inhibition ameliorates liver fibrosis by inducing hepatic stellate cell senescence and depleting hepatic macrophage population.

Persistent activation of hepatic stellate cells (HSCs) in the injured liver leads to the progression of liver injury from fibrosis to detrimental cirrhosis. In a previous study, we have shown that survivin protein is upregulated during the early activation of HSCs, which triggers the onset of liver fibrosis. However, the therapeutic potential of targeting survivin in a fully established fibrotic liver needs to be investigated.

Tranexamic acid in upper gastrointestinal bleed in patients with cirrhosis: A randomized controlled trial.

Background And Aims: Patients with Child-Turcotte-Pugh class B and C cirrhosis with upper gastrointestinal bleeding (UGIB) have systemic as well as localized (in the mucosa of the esophagus and stomach) fibrinolysis. The aim of this study was to evaluate the efficacy and safety of tranexamic acid in the treatment of acute UGIB in patients with cirrhosis.

Approach And Results: A total of 600 patients with advanced liver cirrhosis (Child-Turcotte-Pugh class B or C) presenting with UGIB were randomly allocated to either the tranexamic acid (n=300) or the placebo group (n=300).

Prevalence and clinicopathological Spectrum of Auto-Immune Liver Diseases & Overlap syndrome.

Aims: Autoimmune liver diseases (AILD) represent a spectrum of related yet distinct immune-mediated disorders. The literature on the prevalence of these AILDs in Indian population is scarce. This study aims to assess the prevalence and clinicopathological spectrum of various AILDs especially the overlap syndrome.

Dissociation in hepatic vein pressure gradient, liver stiffness measurement and complications in histological subtypes of porto-sinusoidal vascular disease.

Background And Aims: Portosinusoidal vascular disease (PSVD) is a broad term encompassing varied histological patterns with changes in portal tracts and sinusoids without cirrhosis. We aimed to assess whether there is any clinical and pathological difference among the various histological categories of PSVD.

Patients And Methods: This study included liver biopsy cases classified as PSVD (2020-2022).

18F-Fluorodeoxyglucose Positron Emission Tomography/Computed Tomography in a Rare Case of Epithelioid Hemangioendothelioma - A Diagnostic Challenge.

Our case highlights the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) scan findings in a rare case of biopsy-proven epithelioid hemangioendothelioma (EHE) in a 66-year-old woman with multi-organ involvement (lung, liver, and bone) who was subsequently treated with palliative radiation therapy and oral pazopanib. Furthermore, follow-up 18F-FDG PET/CT findings are detailed. EHE is a rare malignant vascular neoplasm (<1% of all vascular tumors) with an epithelioid and histiocytoid appearance arising from the vascular endothelial and preendothelial cells.

Utility and diagnostic accuracy of intraoperative frozen sections in hepato-pancreato-biliary surgical pathology.

Background And Purpose: Hepato-pancreato-biliary (HPB) surgeries are one of the most challenging and complex procedures. Intraoperative frozen section (IFS) diagnosis plays a pivotal role in management decisions. Comprehensive large cohort studies evaluating utility of IFS in HPB malignancies are lacking.

Cytological Diagnosis of Castleman Disease by Endoscopic Ultrasound Guided Fine Needle Aspiration.

Castleman disease is a nonmalignant, lymphoproliferative disorder. Unicentric disease type involves a single enlarged lymph node or nodal regions, and multicentric disease involves multiple lymph node site involvement. We present a case of 26-year-old young female presented to outpatient with complaint of generalized weakness and abdominal pain for last 2 months.

Autoantibody Positivity Has No Impact on Histological Parameters in Nonalcoholic Fatty Liver Diseases.

Objectives: Previous reports on association of autoantibodies with histological severity in nonalcoholic fatty liver disease (NAFLD) have revealed inconsistent results. Therefore, this study was undertaken to find the impact of autoantibodies on histological severity of NAFLD.

Methods: All cases with histological diagnosis of NAFLD during January 2016 to January 2021 were included in the study.

Vascular Extracellular Vesicles Indicate Severe Hepatopulmonary Syndrome in Cirrhosis.

Background: Hepatopulmonary syndrome (HPS) is a pulmonary vasculature complication in the setting of liver disease that is characterized by pathological vasodilation resulting in arterial oxygenation defects. We investigated the role of extracellular vesicles (EV) in cirrhosis patients with HPS, as well as the functional effect of EV administration in a common bile duct ligation (CBDL) HPS mouse model.

Methods: A total of 113 cirrhosis patients were studied: 42 (Gr.

Hepatopulmonary syndrome is associated with low sphingosine-1-phosphate levels and can be ameliorated by the functional agonist fingolimod.

Background & Aims: Hepatopulmonary syndrome (HPS) is characterised by a defect in arterial oxygenation induced by pulmonary vascular dilatation in patients with liver disease. Fingolimod, a sphingosine-1-phosphate (S1P) receptor modulator, suppresses vasodilation by reducing nitric oxide (NO) production. We investigated the role of S1P in patients with HPS and the role of fingolimod as a therapeutic option in an experimental model of HPS.

Topographic Distribution Pattern in Hepatic Amyloidosis Presenting with Portal Hypertension.

Background/aims: The liver is often involved in both primary and secondary forms of amyloidosis. Significant clinical evidence of portal hypertension is relatively uncommon and seems to be related to the reduced sinusoidal lumen and increased resistance to blood flow due to massive perisinusoidal amyloid deposits. The relationships between the pattern and extent of amyloid deposition in patients presenting with portal hypertension have not yet been clearly demonstrated.

Histological Changes in Portal Cavernoma Cholangiopathy.

Introduction: Portal cavernoma cholangiopathy (PCC)' refers to abnormalities of the extrahepatic and intrahepatic bile ducts in patients with portal hypertension. Although there is data on clinical and imaging aspects of PCC, the description of liver pathology has been strikingly deficient. The purpose of this study was to examine the histopathological characteristics of PCC.

Biliary Epithelial Senescence in Cellular Rejection Following Live Donor Liver Transplantation.

Background: As with the hepatocytes, cholangiocyte senescence can also easily be detected in damaged small bile ducts and bile ductules during liver disease affecting the biliary system and cholangiocytes. Despite cellular senescence being a feature of chronic progressive cholangiopathies in adults, only a few studies have investigated its role in liver transplant rejection.

Method: Transplant biopsies displaying features of rejection were reviewed and classified based on the type of rejection and the time since transplantation.

A comparative histological analysis of early and late graft dysfunction in different time zones following living donor liver transplantation.

Background: Liver biopsy plays a crucial role in evaluating allograft dysfunction. Comprehensive analysis of the histological spectrum of complications, particularly rejection, in different time zones is lacking.

Aim: To evaluate the histological spectrum of rejection, in four time zones, in a large Living donor liver transplant series.

Non-alcoholic fatty liver disease (NAFLD) in lean individuals - Single centre large cohort clinicopathologic and immunophenotypic study.

Background: Non-alcoholic fatty liver disease is one of the most common causes of chronic liver diseases and occurs even in lean individuals having normal or low body mass index (BMI). Crucial issue is understanding the clinical, pathobiologic and metabolic characteristics in comparison to obese patients. Very few studies have compared clinicopathological characteristics between lean and obese.

Emerging Role of Edible Exosomes-Like Nanoparticles (ELNs) as Hepatoprotective Agents.

Liver diseases are responsible for over 2 million deaths each year and the number is rapidly increasing. There is a strong link between edibles, gut microbiota, liver fat and the liver damage. There are very limited therapeutic options for treatment specifically for Alcoholic liver disease (ALD) and Non-Alcoholic liver disease (NAFLD).

Progressive Familial Intrahepatic Cholestasis: Need for Genetic Analysis Before Liver Transplantation.

The clinical course after liver transplantation (LT) in progressive familial intrahepatic cholestasis type 1 (PFIC1) is complicated by intractable diarrhoea, growth failure, graft steatosis and cirrhosis. Recent evidence from Japan suggests the role of genotype to predict outcome after LT. We report a case with pathogenic frameshift mutation who had failed partial external biliary diversion, underwent LT and his post-LT course has been complicated by intractable diarrhoea, growth failure, steatosis and fibrosis.
