Non-cirrhotic portal fibrosis/idiopathic portal hypertension: APASL recommendations for diagnosis and management.

Since the Asian Pacific Association for the Study of the Liver (APASL) published guidelines on non-cirrhotic portal fibrosis/idiopathic portal hypertension in 2007, there has been a surge in new information, especially with the introduction of the term porto-sinusoidal vascular disorder (PSVD). Non-cirrhotic intra-hepatic causes of portal hypertension include disorders with a clearly identifiable etiology, such as schistosomiasis, as well as disorders with an unclear etiology such as non-cirrhotic portal fibrosis (NCPF), also termed idiopathic portal hypertension (IPH). This entity is being increasingly recognized as being associated with systemic disease and drug therapy, especially cancer therapy.

Impact of compensated cirrhosis on survival in patients with acute-on-chronic liver failure.

Background And Aims: Acute-on-chronic liver failure (ACLF) is considered a main prognostic event in patients with chronic liver disease (CLD). We analyzed the 28-day and 90-day mortality in ACLF patients with or without underlying cirrhosis enrolled in the ACLF Research Consortium (AARC) database.

Methods: A total of 1,621 patients were prospectively enrolled and 637 (39.

Association of interleukin-18 genotypes (-607C > A) and (-137 G > C) with the hepatitis B virus disease progression to hepatocellular carcinoma.

Chronic infection with HBV has been reported to be associated with the development of HCC. The inflammation mounted by cytokine-mediated immune system plays an important role in the pathogenesis of HBV-associated HCC. IL-18 is a pro-inflammatory cytokine whose role in the development of HBV-associated chronic to malignant disease state has not been much studied.

Adult onset hereditary hemochromatosis is associated with a novel recurrent Hemojuvelin (HJV) gene mutation in north Indians.

Hereditary hemochromatosis (HH) is a rare disorder in Indians and is not associated with the common mutation Cys282Tyr in HFE gene found in Caucasians. Non-HFE HH can be associated with mutations in HJV, HAMP, TFR2 and SLC40A1 genes. Nineteen unrelated north Indian HH patients were detected after screening 258 chronic liver disease patients on the basis of increased transferrin saturation, ferritin levels >1000 ng/L and siderosis by Perl's stain on liver biopsy wherever available.

Cost of Intensive Care Treatment for Liver Disorders at Tertiary Care Level in India.

We undertook this study to assess the health system costs, out-of-pocket (OOP) expenditure and extent of financial risk protection associated with treatment of liver disorders in a tertiary care public sector hospital in India.

Methodology: The present study was undertaken in an intensive care unit (ICU) of a tertiary care hospital in North India.

Comparison of Contrast Enhanced Ultrasound With Contrast Enhanced Computed Tomography for the Diagnosis of Hepatocellular Carcinoma.

Background/aims: The most common primary malignant tumor of liver is hepatocellular carcinoma (HCC). The highest risk of developing HCC is seen in patients of cirrhosis. Ultrasound is used for surveillance in these patients.

Acute Liver Failure Due to Etodolac, a Selective Cycloxygenase- 2 (COX -2) Inhibitor Non-Steroidal Anti-Inflammatory Drug Established by RUCAM-Based Causality Assessment.

Drug induced liver injury is a common cause of acute liver failure (ALF). While most of these cases are due to dose dependent hepatotoxicity with acetaminophen, idiosyncratic drug-induced liver injury (DILI) is responsible for about 15% cases of ALF. Antibiotics are the most common cause of idiosyncratic DILI as well as DILI induced ALF.

Development of predisposition, injury, response, organ failure model for predicting acute kidney injury in acute on chronic liver failure.

Background And Aim: There is limited data on predictors of acute kidney injury in acute on chronic liver failure. We developed a PIRO model (Predisposition, Injury, Response, Organ failure) for predicting acute kidney injury in a multicentric cohort of acute on chronic liver failure patients.

Patients And Methods: Data of 2360 patients from APASL-ACLF Research Consortium (AARC) was analysed.

Noninvasive Assessment of Liver Fibrosis By Transient Elastography and FIB4/APRI for Prediction of Treatment Response in Chronic Hepatitis C-An Experience from a Tertiary Care Hospital.

Background: Liver fibrosis and its sequel cirrhosis represent a major health care burden, and assessment of fibrosis by biopsy is gradually being replaced by noninvasive methods. In clinical practice, the determination of fibrosis stage is important, since patients with advanced fibrosis have faster progression to cirrhosis and antiviral therapy is indicated in these patients.

Aims: To assess the role of transient elastography (TE) and compare it with APRI and FIB4 for predicting liver fibrosis and assessing the effect of host and viral factors on fibrosis and treatment outcome in CHC patients.

A molecular marker of disease activity in autoimmune liver diseases with histopathological correlation; FoXp3/RORγt ratio.

Autoimmune liver diseases (AILDs) encompass a group of diseases with variable clinicopathological manifestations. Th17 and Treg cells have roles in the pathogenesis of AILDs with a balance shifted towards a relative increase in activity of the Th17 cells. In this study, the balance between the transcription factors of Treg and Th17 cells (FoXp3 and RORγt) was sought as a molecular marker of disease activity and to highlight the pathogenesis.

Risk Factors for Transfusion Transmissible Infections Elicited on Post Donation Counselling in Blood Donors: Need to Strengthen Pre-donation Counselling.

Donor notification and counselling transforms the legal and ethical requirement of disclosure of transfusion transmissible infection (TTI) in a blood donor into practice. The present study was done to assess the response to the disclosure of TTI reactivity results in blood donors, assess the risk factors in blood donors and follow the compliance of the disclosure and clinical referral in a population of blood donors who are difficult to convince that they may be harbouring infections apparently in a healthy state today but with possible clinical disease consequences in the future. A retrospective study was conducted from April 2011 to November 2012.

Association of interleukin-10 with hepatitis B virus (HBV) mediated disease progression in Indian population.

Background & Objectives: Interleukin (IL)-10, an anti-inflammatory Th2 cytokine, is one of the key coordinators of the inflammatory responses involved. The present study was designed to evaluate the impact of IL-10 (-819/-592) genotypes, haplotypes, mRNA and the protein levels with risk for hepatitis B virus (HBV) related hepatocellular carcinoma (HCC) development in India.

Methods: A total of 390 subjects (145 controls, 62 inactive HBV-carriers, 64 chronic-active HBV patients, 60 HBV related cirrhotics and 59 HBV- HCC subjects) were enrolled in the study.

Methods: For this, 403 participants (153 controls, 61 inactive HBV-carriers, 65 chronic-active HBV patients, 63 HBV-cirrhotics, and 61 HBV-HCC participants) were enrolled in the study. Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), ELISA, and RT-PCR methods were used for assessing polymorphism, protein, and the mRNA levels, respectively, of IL-6.

Severity of hepatitis C virus (genotype-3) infection positively correlates with circulating microRNA-122 in patients sera.

Introduction: Hepatitis C virus (genotype-3) causes acute and chronic hepatitis infection predomination in India. The infectious phase of the virus requires various host factors for its survival and subsequent viral particle production. Small RNA molecules like microRNA-122 (miR-122) are one such factor mostly present in the liver and play a supportive role in viral replication.

Paroxysmal Nocturnal Hemoglobinuria is rare cause for thrombosis of the intra-abdominal veins in the ethnic Indian population - results from FLAER-based flowcytometry screening.

Background: Paroxysmal nocturnal hemoglobinuria (PNH) may present as cytopenia, hemolysis, or thrombosis at unusual sites including splanchnic vessels. Thrombosis of the portal veins and hepatic veins are associated with thrombophilic risk factors: deficiencies of protein C, protein S, and antithrombin, positivity for antiphospholipid antibodies, and factor V Leiden mutation. There is limited information regarding PNH presenting primarily as a thrombotic event.

Obesity and NAFLD: the role of bacteria and microbiota.

There are trillions of microorganisms in the human intestine collectively called gut microbiota. Obesity may be affected by the gut microbiota through energy harvesting and fat storage by the bacteria. Small intestinal bacterial overgrowth is also responsible for endotoxemia, systemic inflammation, and its consequences including obesity and nonalcoholic fatty liver disease (NAFLD).

Effect of IL-12B, IL-2, TGF-β1, and IL-4 polymorphism and expression on hepatitis B progression.

The hepatitis B virus (HBV) infection-induced chronic inflammation is considered to be the major etiological factor for HBV-related disease chronicity. Cytokines act as the key coordinators of the inflammatory responses involved in HBV disease pathogenesis. The present study assessed association among IL-12B(+1188), IL-2(-330), TGF-β1(-509), and IL-4(-590) genotypes; mRNA; and protein levels with HBV-hepatocellular carcinoma (HCC) risk in India.

IFN-γ (+874) and not TNF-α (-308) is associated with HBV-HCC risk in India.

Tumor necrosis factor (TNF)-α and interferon (IFN)-γ, the pro-inflammatory Th1 cytokines are the indispensable coordinators of the inflammatory responses involved in hepatitis B virus (HBV) pathogenesis. This study attempted to evaluate any possible association among TNF-α (-308G>A) and IFN-γ (+874T/A) genotypes, the spontaneous blood and mRNA levels and expression of their major signal transducers, namely STAT1 and NF-кB with hepatitis B virus-induced hepatocellular carcinoma (HCC) susceptibility in India. For this, 398 subjects (146 controls, 68 inactive-HBV-carriers, 64 chronic-active HBV patients, 61 HBV-cirrhotics, and 59 HBV-HCC subjects) were enrolled.

Angiogenic and anti-angiogenic factor gene transcript level quantitation by quantitative real time PCR in patients with hepatocellular carcinoma.

Tumor angiogenesis, a major requirement for tumor growth and metastasis, is regulated by pro- and anti-angiogenic factors. The aim of this study was to quantify the expression of angiogenic (VEGF, HIF-1α, Angiopiotein-2) and anti-angiogenic (endostatin, angiostatin and Thrombospondin-1) factors and to discern their clinical relevance. A total 90 patients (67 HCC, 9 cirrhosis and 14 chronic hepatitis) were enrolled in the study.

Serum levels of angiogenic and anti-angiogenic factors: their prognostic relevance in locally advanced hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a prototype tumor wherein angiogenesis plays a vital role in its progression. The role of VEGF, a major angiogenic factor in HCC is known; however, the role of anti-angiogenic factors simultaneously with the angiogenic factors has not been studied before. Hence, in this study, the serum levels of major angiogenic [Vascular Endothelial Growth Factor (VEGF), angiopoietin-2 (Ang-2)] and anti-angiogenic (endostatin, angiostatin) factors were analyzed and correlated with clinico-radiological features and with outcome.

Association between urinary 6β-hydroxycortisol/cortisol ratio and CYP3A5 genotypes in a normotensive population.

Genetic polymorphism of genes involved in renal salt handling and arterial vessel tone is considered to be one of the causes of hypertension. Numerous reports suggest that cytochrome P4503A5 (CYP3A5) catalyzes 6β-hydroxylation of endogenous cortisol (CS), which is associated with sodium and water retention in the kidney and involved in the regulation of blood pressure. The purpose of the present study was to study the associations of single nucleotide polymorphisms in the CYP3A5 gene with the urinary 6β-hydroxycortisol/cortisol (6β-OH-CS/CS) ratio considered as quantitative phenotypes.
