UNASSIGNED: Increasing incidence of hepatocellular carcinoma (HCC) in India is a matter of concern and need for adequate profiling and streamlining management strategies cannot be over-emphasized.
UNASSIGNED: This is a prospective multi-centric observational cohort study comprising of an oncology center, one university tertiary hospital with specialized hepatology service, one public hospital with gastroenterology service, and a private liver transplant center located within a 3-km radius. The demographic and clinical parameters were recorded on a prospectively maintained database. The clinical profile, demographics, characteristics of HCC and the allocated treatment were noted and compared among the four centers.
UNASSIGNED: In total, 672 patients were enrolled from June 2016 till January 2020. Abdominal pain (64.3%) and weight loss (47.3%) were the most common symptoms. Most common identified etiology was hepatitis B (39%). The cancer center received lesser patients with hepatitis C and those with advanced stage of HCC. The private transplant center reported the highest proportion of NASH, which was also significantly higher in those belonging to higher socioeconomic strata, and lowest proportion of alcoholic cirrhosis. Metastasis was seen in almost one-fifth (19%) cases at diagnosis. Portal vein thrombosis was evident in 40%. Adherence to treatment guidelines was seen in three-fourth cases (76%).
UNASSIGNED: Hepatitis B is the most common underlying cause for HCC, whereas other causes like NASH are on the rise. Etiologic profile may vary with selective specialization of centers catering to patients with HCC. Adherence to guideline while allocating treatment was high among all centers with highest non-adherence in BCLC A.

UNASSIGNED: Gut-barrier dysfunction is well recognized in pathogenesis of both non-alcoholic fatty liver disease (NAFLD) and alcoholic liver disease (ALD). However, comparison of components of this dysfunction between the two etiologies remains unexplored especially in early stages of NAFLD.
UNASSIGNED: Components of gut-barrier dysfunction like alterations in intestinal permeability (IP) by lactulose mannitol ratio (LMR) in urine, systemic endotoxemia (IgG and IgM anti-endotoxin antibodies), systemic inflammation (serum tumor necrosis factor alpha [TNF-α] and interleukin-1 [IL-1] levels), tight junction (TJ) proteins expression in duodenal biopsy and stool microbiota composition using Oxford Nanopore MinION device were prospectively evaluated in patients with NAFLD (n = 34) with no cirrhosis, ALD (n = 28) and were compared with disease free controls (n = 20).
UNASSIGNED: Patients with ALD had more advanced disease than those with NAFLD (median liver stiffness -NAFLD:7.1 kPa [5.9-8.9] vs. ALD:14.3 kPa [9.6-24], P < 0.001]. Median LMR was significantly higher in NAFLD and ALD group when compared to controls (NAFLD 0.054 [0.037-0.17] vs. controls 0.027 [0.021-0.045] (P = 0.001)) and ALD 0.043 [0.03-0.068] vs. controls 0.027 [0.021-0.045] (P = 0.019)]. Anti-endotoxin antibody titer (IgM) (MMU/mL) was lowest in NAFLD 72.9 [3.2-1089.5] compared to ALD 120.6 [20.1-728]) (P = 0.042) and controls 155.3 [23.8-442.9]) (P = 0.021). Median TNF-α (pg/mL) levels were elevated in patients with NAFLD (53.3 [24.5-115]) compared to controls (16.1 [10.8-33.3]) (P < 0.001) and ALD (12.3 [10.1-42.7]) (P < 0.001). Expression of zonulin-1 and claudin-3 in duodenal mucosa was lowest in NAFLD. On principal co-ordinate analysis (PCoA), the global bacterial composition was significantly different across the three groups (PERMANOVA test, P < 0.001).
UNASSIGNED: While remaining activated in both etiologies, gut-barrier dysfunction abnormalities were more pronounced in NAFLD at early stages compared to ALD despite more advanced disease in the latter.

UNASSIGNED: This study analyzes the changing levels of circulating inflammatory cytokines Interferon gamma (IFN-γ) and interleukin (IL)-10 (as the main cytokines of T-helper-1 and T-helper-2 immune responses) in patients with chronic hepatitis C virus (HCV) infection undergoing therapy with direct-acting antivirals (DAAs) and to correlate them with laboratory markers.
UNASSIGNED: This Pilot study included 50 HCV monoinfected patients who received DAAs for 12 or 24 weeks. They were followed up monthly during therapy and 3 months after the end of the treatment. Liver disease was determined by transient elastography, in addition to FIB-4 indices. Analysis of IFN-gamma and IL-10 was carried out using an enzyme-linked immunosorbent assay.
UNASSIGNED: All patients carried HCV genotype 4. The Sustained virological response was 100% and 92% in cirrhotics and noncirrhotics, respectively. There was no significant difference between groups in baseline IL-10 or IFN-gamma. In noncirrhotics, IL-10 showed a significant reduction at Week 4 after treatment start. In cirrhotics, IL-10 showed a significant reduction at Week 4 after treatment starts and a significant reduction at Week 12 after the end of the treatment. At Week 12 after the end of the treatment, serum IL-10 levels were significantly lower in cirrhotics. IFN-γ showed nonsignificant changes in noncirrhotics. A significant increase of IFN-γ occurred in cirrhotics from Week 4 after treatment starts to 12 weeks after the end of the treatment. IFN-γ was significantly higher in cirrhotics at Week 12 after the end of the treatment. IFN-γ and IL-10 showed different correlations with laboratory markers.
UNASSIGNED: Viral eradication induced by DAAs caused a significant change in IL-10 and IFN-gamma.

UNASSIGNED: Liver cirrhosis is a chronic disease in which normal liver tissue is replaced by fibrous tissue, leads to liver malfunction. Although transplantation is the most certain cure, stem cell therapies are shedding light on efforts to regenerate cirrhotic liver. The purpose of this study was to evaluate the regenerative potential of mesenteric fat stem cells in CCL4-induced liver cirrhosis in an animal model.
UNASSIGNED: Thirty rats were treated with the mixture of CCL4 and olive oil intraperitoneally by a dose of 0.2 ml (0.1 ml CCL4 and 0.1 ml olive oil) every other day for 16 weeks till cirrhosis signs appeared. Fifteen rats were randomly selected as control group. Others treated by mesenteric fat derived mesenchymal stem cells transferred into the liver parenchyma.
UNASSIGNED: After 5 weeks, rats received stem cells had improved clinically by increased movements, appetite, improvement in overall behavior and decreased abdomen size. Histopathologically, liver cells showed state of regeneration and forming new colonies.
UNASSIGNED: Liver cirrhosis was induced. The mesenchymal stem cells derived from mesenteric adipose tissue could improve hepatic status of the rats, as cirrhotic livers were regenerated back into normal appearing parenchyma. Rats\' clinical behavior also reached healthy status.

Acute liver failure (ALF) is not an uncommon complication of a common disease such as acute hepatitis. Viral hepatitis followed by antituberculosis drug-induced hepatotoxicity are the commonest causes of ALF in India. Clinically, such patients present with appearance of jaundice, encephalopathy, and coagulopathy. Hepatic encephalopathy (HE) and cerebral edema are central and most important clinical event in the course of ALF, followed by superadded infections, and determine the outcome in these patients. The pathogenesis of encephalopathy and cerebral edema in ALF is unique and multifactorial. Ammonia plays a crucial role in the pathogenesis, and several therapies aim to correct this abnormality. The role of newer ammonia-lowering agents is still evolving. These patients are best managed at a tertiary care hospital with facility for liver transplantation (LT). Aggressive intensive medical management has been documented to salvage a substantial proportion of patients. In those with poor prognostic factors, LT is the only effective therapy that has been shown to improve survival. However, recognizing suitable patients with poor prognosis has remained a challenge. Close monitoring, early identification and treatment of complications, and couseling for transplant form the first-line approach to manage such patients. Recent research shows that use of dynamic prognostic models is better for selecting patients undergoing liver transplantation and timely transplant can save life of patients with ALF with poor prognostic factors.

Acute liver failure (ALF) is an infrequent, unpredictable, potentially fatal complication of acute liver injury (ALI) consequent to varied etiologies. Etiologies of ALF as reported in the literature have regional differences, which affects the clinical presentation and natural course. In this part of the consensus article designed to reflect the clinical practices in India, disease burden, epidemiology, clinical presentation, monitoring, and prognostication have been discussed. In India, viral hepatitis is the most frequent cause of ALF, with drug-induced hepatitis due to antituberculosis drugs being the second most frequent cause. The clinical presentation of ALF is characterized by jaundice, coagulopathy, and encephalopathy. It is important to differentiate ALF from other causes of liver failure, including acute on chronic liver failure, subacute liver failure, as well as certain tropical infections which can mimic this presentation. The disease often has a fulminant clinical course with high short-term mortality. Death is usually attributable to cerebral complications, infections, and resultant multiorgan failure. Timely liver transplantation (LT) can change the outcome, and hence, it is vital to provide intensive care to patients until LT can be arranged. It is equally important to assess prognosis to select patients who are suitable for LT. Several prognostic scores have been proposed, and their comparisons show that indigenously developed dynamic scores have an edge over scores described from the Western world. Management of ALF will be described in part 2 of this document.

Clinical practice guidelines for Wilson\'s disease (WD) have been published by the American Association for the Study of Liver Diseases and European Association for the Study of the Liver in 2008 and 2012, respectively. Their focus was on the hepatic aspects of the disease. Recently, a position paper on pediatric WD was published by the European Society of Pediatric Gastroenterology Hepatology and Nutrition. A need was felt to harmonize guidelines for the hepatic, pediatric, and neurological aspects of the disease and contextualize them to the resource-constrained settings. Therefore, experts from national societies from India representing 3 disciplines, hepatology (Indian National Association for Study of the Liver), pediatric hepatology (Indian Society of Pediatric Gastroenterology, Hepatology and Nutrition), and neurology (Movement Disorders Society of India) got together to evolve fresh guidelines. A literature search on retrospective and prospective studies of WD using MEDLINE (PubMed) was performed. Members voted on each recommendation, using the nominal voting technique. The Grades of Recommendation, Assessment, Development and Evaluation system was used to determine the quality of evidence. Questions related to diagnostic tests, scoring system, and its modification to a version suitable for resource-constrained settings were posed. While ceruloplasmin and 24-h urine copper continue to be important, there is little role of serum copper and penicillamine challenge test in the diagnostic algorithm. A new scoring system - Modified Leipzig score has been suggested with extra points being added for family history and serum ceruloplasmin lower than 5 mg/dl. Liver dry copper estimation and penicillamine challenge test have been removed from the scoring system. Differences in pharmacological approach to neurological and hepatic disease and global monitoring scales have been included. Rising bilirubin and worsening encephalopathy are suggested as indicators predicting need for liver transplant but need to be validated. The clinical practice guidelines provide recommendations for a comprehensive management of WD which will be of value to all specialties.

OBJECTIVE: NAFLD has today emerged as the leading cause of liver disorder. There is scanty data on risk factors associated with NAFLD emanating from India. The present study was conducted to identify the risk factors associated with NAFLD.
METHODS: 464 consecutive NAFLD patients and 181 control patients were subjected to detailed questionnaire regarding their lifestyle and dietary risk factors. Anthropometric measurements were obtained and biochemical assays were done. Comparison of different variables was made between NAFLD patients and controls using principal component analysis (PCA).
RESULTS: NAFLD patients had higher BMI [26.25 ± 3.80 vs 21.46 ± 3.08 kg/m(2), P = 0.000], waist-hip ratio [0.96 ± 0.12 vs 0.90 ± 0.08, P = 0.000] and waist-height ratio [0.57 ± 0.09 vs 0.50 ± 0.06, P = 0.000] compared to controls. Fasting blood sugar [101.88 ± 31.57 vs 90.87 ± 10.74 mg/dl] and triglyceride levels [196.16 ± 102.66 vs 133.20 ± 58.37 mg/dl] were significantly higher in NAFLD group. HOMA-IR was also higher in NAFLD group [2.53 ± 2.57 vs 1.16 ± 0.58, P = 0.000]. Majority (90.2%) of NAFLD patients were sedentary. Family history of metabolic syndrome (MS) was positively correlated with NAFLD. Dietary risk factors associated with NAFLD were non-vegetarian diet [35% vs 23%, P = 0.002], fried food [35% vs 9%, P = 0.000], spicy foods [51% vs 15%, P = 0.001] and tea [55% vs 39%, P = 0.001]. Diabetes, hypertension, snoring and sleep apnoea syndrome were common factors in NAFLD. On multivariate PCA, waist/height ratio and BMI were significantly higher in the NAFLD patients.
CONCLUSIONS: The risk factors associated with NAFLD are sedentary lifestyle, obesity family history of MS, consumption of meat/fish, spicy foods, fried foods and tea. Other risk factors associated with NAFLD included snoring and MS.

OBJECTIVE: The study aimed at assessing the therapeutic efficacy and safety of metadoxine versus placebo on the ultrasonographic and histological features of non-alcoholic steatohepatitis (NASH).
METHODS: 134 subjects with biopsy-confirmed NASH were randomized to receive metadoxine 500 mg two times daily (n = 75) or placebo (n = 59) added to the standard of care, over 16 weeks.
UNASSIGNED: Originally, the primary efficacy endpoint was the composite of: reduction in the steatosis by ≥1 grade, reduction in hepatic necro-inflammation by ≥1 grade and ALT normalization. Since >50% of patients refused the second biopsy, it was decided to analyze only the individual parameters.
RESULTS: There was no significant difference between the treatment and the placebo groups in either liver histology or ALT or AST. Overall, as expected both groups showed reduction in serum ALT and AST compared to baseline. Compared to placebo (9 out 54), patients on metadoxine (34 out of 75) had significantly higher rates of improvement in 1-point in steatosis grade on ultrasound (P-value <0.001). Safety and tolerability did not differ between treatments.
CONCLUSIONS: Metadoxine is not effective in improvement of liver histology or serum ALT or AST in patients with NASH. However, there was significant improvement of steatosis assessed by ultrasound. To properly estimate the effects on histology and transaminases, further studies of longer duration and at higher doses are needed.
