Prognostic role of serial alpha-fetoprotein levels in hepatocellular carcinoma treated with locoregional therapy.

Background and aim: To evaluate early serial AFP changes in responders and non-responders to locoregional therapy and identify differences between significant AFP decliners and non-decliners post-treatment. Methods: Case records of hepatocellular carcinoma (HCC) patients having AFP ≥20 ng/ml and treated with locoregional therapy were examined retrospectively. Patients with complete details were included. Trends of serial AFP change (from baseline to post-treatment one month) in patients showing early tumor response (complete response (CR), partial response (PR), progressive disease (PD)) as assessed on multiphasic MRI/CT liver performed at one month following treatment. Receiver operating curves were drawn to estimate the best AFP reduction cut off for differentiating between responders (CR plus PR) from non-responders (PD). AFP decliners (those with AFP level reduction greater than 20% post-treatment) were identified and comparisons of their clinical parameters, tumor response and survival rate were made with AFP non-decliners. Results: HCC patients (n = 126) had mean age of 52.8 years, male:female ratio (4:1), Child's A 94, BCLC stage A/B/C HCC 49/65/12, respectively. On 4-6 weeks' MRI/CT, 46 patients developed CR, 55 PR and 25 PD. Reduction in median AFP level (83% in CR, 19% in PR) occurred in responders while 16% increase occurred in PD patients (non-responders). A 30% AFP reduction could differentiate responders from non-responders with 70% sensitivity and 68% specificity, AUROC 74% (CI 0.64-0.85). AFP decliners showed better survival and tumor response than non-decliners. Conclusions: Serial AFP change can predict tumor response to locoregional therapy in AFP producing HCC patients. AFP decliners have better survival and tumor response than AFP non-decliners.

Comparison of Dynamic Changes Among Various Prognostic Scores in Viral Hepatitis-Related Acute Liver Failure.

INTRODUCTION AND AIM: Multiple prognostic scores are available for acute liver failure (ALF). Our objective was to compare the dynamicity of model for end stage liver disease (MELD), MELD-sodium, acute liver failure early dynamic model (ALFED), chronic liver failure (CLIF)-consortium ACLF score and King's College Hospital Criteria (KCH) for predicting outcome in ALF. MATERIALS AND METHODS: All consecutive patients with ALF at a tertiary care centre in India were included. MELD, MELD-Na, ALFED, CLIF-C ACLF scores and KCH criteria were calculated at admission and day 3 of admission. Area under receiver operator characteristic curves (AUROC) were compared with DeLong method. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), likelihood ratio (LR) and diagnostic accuracy (DA) were reported. RESULTS: Of the 115 patients included in the study, 73 (63.5%) died. The discrimination of mortality with baseline values of prognostic scores (MELD, MELD-Na, ALFED, CLIF-C ACLF and KCH) was modest (AUROC: 0.65-0.77). The AUROC increased on day 3 for all scores, except KCH criteria. On day 3 of admission, ALFED score had the highest AUROC 0.95, followed by CLIF-C ACLF 0.88, MELD 0.81, MELD-Na 0.77 and KCH 0.52. The AUROC for ALFED was significantly higher than MELD, MELD-Na and KCH (P < 0.001 for all) and CLIF-C ACLF (P = 0.05). ALFED score ≥ 4 on day 3 had the best sensitivity (87.1%), specificity (89.5%), PPV (93.8%), NPV (79.1%), LR positive (8.3) and DA (87.9%) for predicting mortality. CONCLUSIONS: Dynamic assessment of prognostic scores better predicts outcome. ALFED model performs better than MELD, MELD, MELD-Na, CLIF-C ACLF scores and KCH criteria for predicting outcome in viral hepatitis- related ALF.

Severity and Outcome of Acute-on-Chronic Liver Failure is Dependent on the Etiology of Acute Hepatic Insults: Analysis of 368 Patients.

BACKGROUND: Acute-on-chronic liver failure (ACLF) may be precipitated by various hepatic insults. The present study evaluated the outcomes of ACLF with different acute insults. PATIENTS AND METHODS: A total of 368 ACLF patients were included. Data collected included etiologies of acute hepatic insult and underlying chronic liver disease, and organ failure. Model for end-stage liver disease (MELD), chronic liver failure consortium (CLIF)-C ACLF, and acute physiology and chronic health evaluation (APACHE) II scores were calculated. Predictors of survival were assessed by the Cox proportional hazard model. RESULTS: The most frequent acute insult was active alcohol consumption [150 (40.8%) patients], followed by hepatitis B virus (HBV) [71 (19.3%) patients], hepatitis E virus (HEV) superinfection [45 (12.2%) patients], autoimmune hepatitis flare [17 (4.6%) patients], antituberculosis drugs [16 (4.3%) patients], and hepatitis A virus superinfection [2 (0.5%) patients]; 67 (18.2%) cases were cryptogenic. Alcohol-ACLF and cryptogenic-ACLF were more severe. Median CLIF-C, MELD, and APACHE II scores in alcohol-ACLF and cryptogenic-ACLF were significantly higher than those in HBV-ACLF and HEV-ACLF (CLIF-C: 47.1, 47.4 vs. 42.9, 42.0, P=0.002; MELD: 29, 29.9 vs. 28.9, 25.2, P=0.02; APACHE II: 16.5, 18.0 vs. 12, 14, P<0.001, respectively). Frequencies of kidney and brain failures were also higher in alcohol/cryptogenic-ACLF than in HBV/HEV-ACLF (kidney failure: 35.3%/34.3% vs. 23.9%/11.1%, P=0.009; brain failure: 26.0%/22.4% vs. 15.5%/4.4%, P=0.01, respectively). Mortality in the alcohol-ACLF group was the highest (64.0%), followed by that in the cryptogenic-ACLF (62.7%), HBV-ACLF (45.1%), and HEV-ACLF (17.8%) groups (P<0.001). In multivariable analysis, alcohol-ACLF had significantly higher mortality compared with HEV-ACLF (hazard ratio, 3.06; 95% confidence interval, 1.10-8.49, P=0.03). CONCLUSIONS: Alcohol/cryptogenic-ACLF had more severe phenotypic presentation, more incidence of organ failures, and higher mortality compared with HEV/HBV-ACLF. Alcohol-ACLF had the highest mortality, whereas HEV-ACLF had the best survival.

Predictors of infection in viral-hepatitis related acute liver failure.

OBJECTIVE: Infections are common and associated with complications and mortality in acute liver failure (ALF). The temporal relationship between ammonia and infection in ALF patients is unclear. We aimed to evaluate the predictors of infection and its relationship with arterial ammonia levels. MATERIALS AND METHODS: Consecutive ALF patients hospitalized between January 2004 and December 2015, without signs of infection at/within 48 h of admission, were included. Occurrence of infection after 48 h was documented and ammonia levels were estimated for five consecutive days. Multivariate logistic regression analysis was used to assess factors associated with development of infection. Generalized estimating equations (GEE) were used to evaluate five-day time trend of ammonia in patients with and without infection. RESULTS: Of 540 consecutive patients, 120 were infected at admission/within 48 h and were excluded. Of the rest 420 patients, 144 (34.3%) developed infection after 48 h and 276 (65.7%) remained non-infected. Infected patients had higher mortality than non-infected patients (61.8% vs 40.0%, p < .001). On multivariate analysis, presence of cerebral edema(HR 2.049; 95%CI, 1.30-3.23), ammonia level on day 3 of admission (HR 1.006; 95%CI, 1.003-1.008), and model for end stage liver disease (MELD) score (HR 1.051; 95%CI, 1.026-1.078) were associated with development of infection. GEE showed group difference in serial ammonia values between infected and non-infected patients indicating lack of ammonia decline in infected patients. CONCLUSIONS: Cerebral edema, elevated ammonia on day 3, and higher MELD score predict the development of infection in ALF. Ammonia persists at high levels in infected patients, and elevated ammonia on day 3 is associated with complications and death.

Acute-on-chronic liver failure in India: The Indian National Association for Study of the Liver consortium experience.

BACKGROUND AND AIM: The aim of this study was to analyze etiologies and frequency of hepatic and extrahepatic organ failures (OFs) and outcome of acute-on-chronic liver failure (ACLF) at 10 tertiary centers in India. METHODS: In this retrospective study (2011-2014), patients satisfying Asian Pacific Association for the Study of the Liver definition of ACLF were included. Etiology of acute precipitating insult and chronic liver disease and outcomes were assessed. Occurrence and severity of OF were assessed by chronic liver failure-sequential organ failure assessment score. RESULTS: The mean (±SD) age of 1049 consecutive ACLF patients was 44.7 ± 12.2 years; Eighty-two percent were men. Etiology of acute precipitants included alcohol 35.7%, hepatitis viruses (hepatitis A, hepatitis B, and hepatitis E) 21.4%, sepsis 16.6%, variceal bleeding 8.4%, drugs 5.7%, and cryptogenic 9.9%. Among causes of chronic liver disease, alcohol was commonest 56.7%, followed by cryptogenic and hepatitis viruses. Predictors of survival were analyzed for a subset of 381 ACLF patients; OF's liver, renal, coagulation, cerebral, respiratory, and failure were seen in 68%, 32%, 31.5%, 22.6%, 14.5%, and 15%, respectively. Fifty-seven patients had no OF, whereas 1, 2, 3, 4, and 5 OFs were recorded in 126, 86, 72, 28, and 12 patients, respectively. The mortality increased progressively with increasing number of OFs (12.3% with no OF, 83.3% with five OFs). During a median hospital stay of 8 days, 42.6% (447/1049) of patients died. On multivariate analysis by Cox proportional hazard model, elevated serum creatinine (hazard ratio [HR] 1.176), advanced hepatic encephalopathy (HR 2.698), and requirement of ventilator support (HR 2.484) were independent predictors of mortality. CONCLUSIONS: Alcohol was the commonest etiology of ACLF. Within a mean hospital stay of 8 days, 42% patients died. OFs independently predicted survival.

The Story of Ammonia in Liver Disease: An Unraveling Continuum.

Hyperammonemia and liver disease are closely linked. Most of the ammonia in our body is produced by transamination and deamination activities involving amino acid, purine, pyrimidines, and biogenic amines, and from the intestine by bacterial splitting of urea. The only way of excretion from the body is by hepatic conversion of ammonia to urea. Hyperammonemia is associated with widespread toxicities such as cerebral edema, hepatic encephalopathy, immune dysfunction, promoting fibrosis, and carcinogenesis. Over the past two decades, it has been increasingly utilized for prognostication of cirrhosis, acute liver failure as well as acute on chronic liver failure. The laboratory assessment of hyperammonemia has certain limitations, despite which its value in the assessment of various forms of liver disease cannot be negated. It may soon become an important tool to make therapeutic decisions about the use of prophylactic and definitive treatment in various forms of liver disease.

A Study of Impact of Fixed-Dose Albumin Infusion on Outcome in Patients With Cirrhosis and Infection: A Randomized Open-label Clinical Trial.

Background and aim: Antibiotics and albumin infusion constitute the standard of treatment in patients with decompensated cirrhosis who have spontaneous bacterial peritonitis (SBP). Recent studies have also shown that the use of albumin in patients with advanced liver disease who have infections other than SBP leads to the resolution of acute and chronic liver failure and prevents the development of nosocomial infections. The recommended dose of albumin for these patients is out of reach for many in resource-limited settings like India. The evidence for this recommendation is also scarce. This study aimed to assess the efficacy of a lower dose of albumin infusion in addition to antibiotics on short-term mortality and morbidity in patients with cirrhosis and infections. Patients and methods: A prospective, open-label, randomized control study was performed. Consecutive patients with cirrhosis and infections were randomized in a 2:1 ratio into two groups: group A (116) and group B (58) patients. In addition to antibiotics and standard medical therapy, group A was given albumin in a dose of 20 g/day for five days, and group B was given the recommended dose (1.5 g/kg/body weight and 1 g/kg body weight on days one and three, respectively). The primary outcome was in-hospital mortality. Secondary outcomes were improvements in clinical and laboratory parameters. Results: Except for etiology, all the baseline clinical and laboratory variables in both groups were comparable. The in-hospital mortality in groups A and B was (11 [10.67%] vs. 6 [10.09%], (P = 0.965). The duration of hospitalization, 30-day mortality, improvement in shock and sensorium, and absolute improvements in serum creatinine, international normalized ratio (INR), and serum bilirubin were also comparable in both groups. Conclusion: Low-dose albumin infusion in patients with cirrhosis and infections can have the same results as standard-dose albumin and can be used in resource-limited situations. Clinical trial registration number: CTRI/2020/03/023794.

2023 Update of Indian National Association for Study of the Liver Consensus on Management of Intermediate and Advanced Hepatocellular Carcinoma: The Puri III Recommendations.

Hepatocellular carcinoma (HCC) presents significant treatment challenges despite considerable advancements in its management. The Indian National Association for the Study of the Liver (INASL) first published its guidelines to aid healthcare professionals in the diagnosis and treatment of HCC in 2014. These guidelines were subsequently updated in 2019. However, INASL has recognized the need to revise its guidelines in 2023 due to recent rapid advancements in the diagnosis and management of HCC, particularly for intermediate and advanced stages. The aim is to provide healthcare professionals with evidence-based recommendations tailored to the Indian context. To accomplish this, a task force was formed, and a two-day round table discussion was held in Puri, Odisha. During this event, experts in their respective fields deliberated and finalized consensus statements to develop these updated guidelines. The 2023 INASL guidelines offer a comprehensive framework for the diagnosis, staging, and management of intermediate and advanced HCC in India. They represent a significant step forward in standardizing clinical practices nationwide, with the primary objective of ensuring that patients with HCC receive the best possible care based on the latest evidence. The guidelines cover various topics related to intermediate and advanced HCC, including biomarkers of aggressive behavior, staging, treatment options, and follow-up care.

Fibroscan can avoid liver biopsy in Indian patients with chronic hepatitis B.

BACKGROUND AND AIM: Liver fibrosis is an established determinant of prognosis and therapy in chronic hepatitis B (CHB). The role of fibroscan in assessing fibrosis in CHB remains unclear. Present study was designed to correlate fibroscan with liver biopsy and determine whether fibroscan can avoid liver biopsy in patients with CHB. METHODS: Fibroscan and liver biopsy were performed in 382 consecutive patients with CHB. Biopsies were reviewed by pathologist blinded to the fibroscan value. Discriminant values of liver stiffness measurement (LSM) to reasonably exclude and predict significant fibrosis were calculated from receiver operating characteristic (ROC) curves. The factors affecting LSM independent of fibrosis were assessed. RESULTS: Three hundred fifty-seven patients were included (mean age 30.1 ± 9.7 years, male : female 17 : 3). There was significant correlation between LSM and histological fibrosis (r = 0.58, P < 0.001). The area under ROC curve of LSM for significant fibrosis (F0-1 vs. F2-4), bridging fibrosis (F0-2 vs. F3-4), and cirrhosis (F0-3 vs. F4) was 0.84 (95% CI: 0.78-0.89), 0.94 (95% CI: 0.89-0.99), and 0.93 (95% CI: 0.85-1.00), respectively. LSM < 6.0 KPa could exclude significant (F ≥ 2) and bridging fibrosis (F ≥ 3) with a negative predictive value (NPV) of 92.4% and 99.5%, respectively. Cut-off of 9 KPa could detect significant (F ≥ 2) and bridging fibrosis (F ≥ 3) with specificity of 95% and 97%, respectively, and had a positive predictive value (PPV) of 84.3% in predicting significant fibrosis. LSM < 6 KPa and > 9 KPa matched with histological fibrosis in 227/250 (91%) patients. Therefore, fibroscan could avoid liver biopsy in 70% (250/357) patients with an accuracy > 90%. Histological fibrosis, ALT > 5 times, and age > 40 years were independent determinants of increased liver stiffness. CONCLUSIONS: Fibroscan accurately assessed fibrosis and could avoid liver biopsy in more than two-thirds of patients with CHB.

Incidence and Predictors of Liver-Related Events in Patients With Nonalcoholic Fatty Liver Disease.

Background: Nonalcoholic fatty liver disease (NAFLD) is the commonest type of liver disease worldwide. We aimed to assess the incidence and predictors of liver-related events (LREs) and mortality in NAFLD patients. Methods: NAFLD patients (n = 957) evaluated between January 2000 and November 2021 were included. Patients were categorised as noncirrhosis (NC), compensated cirrhosis (CC) and decompensated cirrhosis (DC), and the incidence of LRE and mortality were estimated and compared. Results: The proportions of NC, CC and DC were 87.8% (n = 840), 8.8% (n = 84) and 3.4% (n = 33), respectively. The median follow-up duration was 3.9 (3.0-5.7) years, and the total cumulative duration was 4633 person-years. The incidence of LRE per 100 person-years was 0.14, 2.72 and 10.24 in patients with NC, CC and DC, respectively. The incidence of mortality was 0.12, 1.05 and 4.24 per 100 person-years, respectively, in the 3 groups. The causes of mortality in the 3 groups were liver related in 1/5 (20%), 3/4 (75%) and 6/9 (66.7%), respectively. Overall, the mortality rate was higher in those with diabetes than those without diabetes (log-rank P value = 0.005). On further analysis, diabetes was associated with poor outcomes only in NC group (log-rank P value = 0.036), and not in CC (log-rank P value = 0.353) or DC groups (log-rank P value = 0.771). On multivariate Cox proportional hazard analysis, age (hazard ratio [HR] 1.070), hypertension (HR 4.361) and DC (HR 15.036) were independent predictors of poor outcomes. Liver stiffness measurement, bilirubin, CC and DC were independent predictors of LRE. Conclusion: In our study of NAFLD from India, the incidence of LRE was found to be similar to that seen in Western studies. In NC NAFLD, diabetes was associated with poor outcomes.

INASL-SAASL Consensus Statements on NAFLD Name Change to MAFLD.

There is an ongoing debate on the change of terminology of non-alcoholic fatty liver disease (NAFLD) to metabolic associated fatty liver disease (MAFLD). Experts from the Indian National Association for Study of the Liver (INASL) and the South Asian Association for Study of the Liver (SAASL) involved in diagnosing, managing, and preventing NAFLD met in March 2022 to deliberate if the name change from NAFLD to MAFLD is appropriate, as proposed by a group of experts who published a "consensus" statement in 2020. Proponents of name change to MAFLD opined that NAFLD does not reflect current knowledge, and the term MAFLD was suggested as a more appropriate overarching term. However, this "consensus" group which proposed the name change to MAFLD did not represent the views and opinions of gastroenterologists and hepatologists, as well as perceptions of patients across the globe, given the fact that change of nomenclature for any disease entity is bound to have multidimensional impact on all aspects of patient care. This statement is the culmination of the participants' combined efforts who presented recommendations on specific issues concerning the proposed name change. The recommendations were then circulated to all the core group members and updated based on a systematic literature search. Finally, all the members voted on them using the nominal voting technique as per the standard guidelines. The quality of evidence was adapted from the Grades of Recommendation, Assessment, Development and Evaluation system.

Indian National Association for Study of the Liver (INASL) Guidance Paper on Nomenclature, Diagnosis and Treatment of Nonalcoholic Fatty Liver Disease (NAFLD).

Nonalcoholic fatty liver disease (NAFLD) is a major cause of chronic liver disease globally and in India. The already high burden of NAFLD in India is expected to further increase in the future in parallel with the ongoing epidemics of obesity and type 2 diabetes mellitus. Given the high prevalence of NAFLD in the community, it is crucial to identify those at risk of progressive liver disease to streamline referral and guide proper management. Existing guidelines on NAFLD by various international societies fail to capture the entire landscape of NAFLD in India and are often difficult to incorporate in clinical practice due to fundamental differences in sociocultural aspects and health infrastructure available in India. A lot of progress has been made in the field of NAFLD in the 7 years since the initial position paper by the Indian National Association for the Study of Liver on NAFLD in 2015. Further, the ongoing debate on the nomenclature of NAFLD is creating undue confusion among clinical practitioners. The ensuing comprehensive review provides consensus-based, guidance statements on the nomenclature, diagnosis, and treatment of NAFLD that are practically implementable in the Indian setting.

Association of pro-inflammatory cytokines, adipokines & oxidative stress with insulin resistance & non-alcoholic fatty liver disease.

BACKGROUND & OBJECTIVES: The cytokines, adipokines, and oxidative stress have been implicated in the pathogenesis of non-alcoholic fatty liver disease (NAFLD); however, such data remain scarce in India. The present study evaluated pro-inflammatory cytokines, adipokines, and markers of oxidative stress in patients with non-alcoholic fatty liver disease (NAFLD), and their association with degree of adiposity, insulin resistance and markers of disease severity. METHODS: The present prospective cross-sectional pilot study included 79 subjects; 34 NAFLD, 22 chronic hepatitis B (CH-B) and 23 healthy controls (HC). The parameters studied were adiponectin, leptin, tumour necrosis factor α (TNFα), interleukin-1 and 6 (IL-1, IL-6), and systemic markers of oxidative stress. RESULTS: The mean body mass index (kg/m 2 ) in NAFLD patients, CHB, and HC were 26.4±3.7, 21.3±2.3, and 22.3±2.7, respectively. The median serum levels of all pro-inflammatory cytokines were significantly higher (P<0.001) in NAFLD compared to control groups. Compared to HC, levels of adiponectin and leptin were significantly (P<0.05, P<0.01) reduced in both NAFLD and CHB. IL-6 showed marked and selective increase only in NAFLD patients. The levels of IL-6 were significantly (P<0.02) higher in NAFLD patients with advanced histology grade and correlated with IR (r=0.42, P=0.02). In a sub-group, markers of oxidative stress were significantly higher, and that of antioxidant potential were significantly lower among NAFLD patients compared to control subjects. INTERPRETATION & CONCLUSIONS: Patients with NAFLD revealed significantly elevated levels of pro-inflammatory cytokines, increased oxidative stress, and a significant association of IL-6 with IR and advanced histopathology.

Splenectomy in cirrhosis with hypersplenism: improvement in cytopenias, Child's status and institution of specific treatment for hepatitis C with success.

INTRODUCTION: Hypersplenism in cirrhosis is not infrequent and may compromise with quality of life and therapy. Splenectomy is a therapeutic option, but information on results of splenectomy is scarce. MATERIAL AND METHODS: Consecutive patients with cirrhosis who underwent splenectomy between 2001-2010 were included in the study. Safety, efficacy of splenectomy and subsequent influence on therapy were evaluated. RESULTS: Thirty three patients (mean age 30.9 ± 11.6 years, 19 men, viral 48.5%, autoimmune 15.1%, cryptogenic 36.4%) underwent splenectomy. Twenty were Child's A, 13 Child's B. Twenty patients had > 6 months follow up. Common indications were inability to treat with interferon, transfusion-dependent anemia, recurrent mucosal bleeds, and large spleen compromising quality of life. Median hospital stay was 7 (4-24) days. There was no splenectomy related mortality. Twenty three (70%) patients had post-operative complications, most commonly infections. Two patients required percutaneous drainage of post-operative collections, and 1 needed re-exploration for intra-abdominal bleed. Subsequent to splenectomy platelet count (44,000 to 151,000/mm 3 , p < 0.01) and TLC (2,500 to 13,400/mm 3 , p < 0.01) had sustained increase in all patients except one. Five HCV cirrhotics completed interferon and ribavirin therapy, 4 achieved sustained viral response. The quality of life improved and there was no recurrence of infections, mucosal bleed or anemia requiring transfusions in any patient. In patients on long term follow up (median duration 27 months), the median Child's score improved from 6 at baseline to 5 at follow up (p < 0.05). CONCLUSIONS: Splenectomy was safe and effective in patients with cirrhosis, and improved therapeutic options as well as Child's score.

Adapting the Utility of Lipiodol CT in Treating Small Hepatocellular Carcinoma.

Introduction: Multiphase MRI liver is the gold-standard imaging modality for staging hepatocellular carcinoma (HCC) in patients with cirrhosis. Often, small HCCs diagnosed on multiphase MRI are occult on B-mode ultrasound and multiphase CT (MPCT) and thus pose a challenge for loco-regional therapy. We adapted the technique of lipiodol CT in treating two such patients of small HCC. Methods: Lipiodol-CT involved an intra-arterial lipiodol injection through the hepatic artery followed by a noncontrast CT liver. CT delineated small, hyperdense, lipiodol-laden hepatic nodules, which served as a target for executing ablation of the nodule and also revealed the true disease stage by depicting the additional number of tumors in the liver. Results: Case one was a 51-year female, known case of chronic hepatitis C who presented with ascites for two months. She was diagnosed with a small HCC (LI-RADS-4) in a cirrhotic liver on multiphase MRI. Percutaneous radiofrequency ablation was planned, but the mass was not located on ultrasound or multiphase CT. Lipiodol-CT was undertaken, which delineated the lipiodol-laden small HCC, which served as a target for executing ablation. Case 2 was a 55-year male, Child-Pugh A cirrhotic, who had undergone right extended hepatectomy for hepatitis B-related HCC. Follow-up MRI revealed a 5 mm segment III nodule, which had increased in size on repeat MRI at 3 months (LI-RADS-4). This nodule, too, was occult on both ultrasound and MPCT. Lipiodol CT revealed additional multiple, variable-sized lipiodol-laden nodules in the liver remnant. Treatment of trans-arterial chemoembolization was performed at one month. Both patients showed complete response to treatment. Conclusion: Lipiodol CT can be safely used in a new role of facilitating treatment of small HCCs diagnosed on MRI but occult on ultrasonography and MPCT.

Spectrum of Neuroimaging Abnormalities in Brain in Patients of Acute-on-Chronic Liver Failure.

Background and aims: Acute-on-chronic liver failure (ACLF) is associated with high short-term mortality. There is a paucity of data about the spectrum of neuroimaging abnormalities in the brain in ACLF patients. The present study was aimed to study the prevalence of cerebral edema and other parenchymal changes in MR imaging of the brain in patients with ACLF. Methods: In this prospective observational study, MR imaging was done in patients with ACLF (n = 41), and findings were compared with age and sex-matched patients with acute decompensation (AD) (n = 13) and those with cirrhosis but without any decompensation at recruitment (n = 21). Results: Forty-one patients with ACLF (24.4% Grade 1 and Grade 2, 51.2% Grade 3) with 14 (34.1%) having cerebral failure were included in the study. T2-weighted (T2W) diffuse white matter hyperintensities (WMHs) and focal WMHs were seen in 17 (41.4%) and 7 (17%) patients, respectively. T1W basal ganglia hyperintensities in 20 (48.7%), cerebral microbleeds (CMBs) in 6 (14.6%), and 2 (4.8%) patients had cerebral edema. In patients with AD, T2W diffuse WMHs were seen in 3 (23%), T2W focal WMHs in 3 (23%) patients. None of the patients with AD had cerebral edema or CMBs. In compensated cirrhosis patients, T2W diffuse WMHs were present in 7 (33.3%), T2W focal WMHs in 5 (23.8%), while 3 (14.2%) patients had CMBs. T1 weighted hyperintensities in basal ganglia were more common in AD [9 (69.2%)] and compensated cirrhosis [15 (71.4%)] as compared to ACLF patients [20 (48.7%)], P = 0.174. The survival time of 30 and 90 days for patients with diffuse T2W WMHs was significantly lesser than patients without T2W WMHs (P = 0.007). Conclusion: Cerebral edema is uncommon in ACLF patients, and T2-weighted diffuse white matter hyperintensities may be associated with worse outcomes. However, due to the limited scope of the present study, the same needs to be explored further in larger cohorts.

Effect of Nonalcoholic Fatty Liver Disease (NAFLD) on COVID-19: A Single-Center Study of 3983 Patients With Review of Literature.

Background The presence of metabolic syndrome (MS) is associated with increased disease severity in patients with coronavirus disease 2019 (COVID-19). Non-alcoholic fatty liver disease (NAFLD) associated with or without MS may be related to increased morbidity and mortality in COVID-19, but large Indian studies are lacking. The present study was carried out to assess the impact of NAFLD on the clinical outcomes in patients with COVID-19 infection. Methods All patients with COVID-19 hospitalized at a tertiary care hospital in eastern India from April 4 to December 31, 2020, were included in the study. Patients who underwent non-contrast CT (NCCT) chest were evaluated for the presence of hepatic steatosis based on a validated criterion liver attenuation (HU) value lower than the spleen, absolute liver attenuation lower than 40 HU, and liver to spleen attenuation ratio less than 1. Patients were divided into two groups, those with or without fatty liver. Baseline characteristics including age, sex, liver function tests, and outcomes including duration of hospital stay and mortality were compared. Results A total of 6003 COVID-19-positive patients were admitted during the study period. Of these patients, 214 children (<18 years) with COVID-19 infection were excluded. One hundred and eight patients with a history of significant ethanol abuse were excluded from the analysis. NCCT scan was not done in 1698 patients. Finally, 3983 patients were included in the study. They were divided into two groups depending on the presence or absence of NAFLD. Of the 3983 patients, 814 (20.4%) had NAFLD. Overall in-hospital mortality among the study group was 6.4%. The mortality rate among patients with NAFLD was 6.7% while that in patients without fatty liver was 6% (P=0.381). Similarly, the mean duration of hospital stay was also comparable between both the groups (10.63±7.2days vs 10.65±6.6 days;P=0.66). Prevalence of NAFLD was similar in survivors and non-survivors; 759 of 2981 patients (25.4%) and 55 of 188 patients 29.2% (P=0.381), respectively. On univariate analysis, male sex, older age, elevated alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transpeptidase (GGT) along with low serum albumin and low absolute eosinophil counts (AEC) were associated with higher mortality. However, on multivariate analysis, only older age, male sex, and low albumin levels were associated with higher mortality. Surprisingly, a sub-group analysis showed that females without NAFLD were at a higher risk of mortality than those with fatty liver (4.9% vs 12.3%; P=0.006). Similarly, patients with lower AST levels had higher mortality compared to patients with significantly elevated AST levels (more than two times the upper limit of normal (ULN)), irrespective of the presence of fatty liver. Conclusions The prevalence of fatty liver in severe acute respiratory syndrome coronavirus 2 (SARS CoV-2) infected patients is similar to the general population in India, the presence of which is not a predictor of severe disease. However, mortality is higher in males and elderly patients.

Histologic Changes in Core-Needle Liver Biopsies From Patients With Acute-on-Chronic Liver Failure and Independent Histologic Predictors of 28-Day Mortality.

CONTEXT.­: The histologic features in patients with acute-on-chronic liver failure (ACLF) are evolving, and histologic indicators of patients' poor prognosis are not yet fully established. OBJECTIVE.­: To evaluate the independent histologic predictors of 28-day mortality in ACLF patients on core-needle liver biopsies. DESIGN.­: Core-needle biopsies from patients with a diagnosis of ACLF (n = 152) as per the European Association for the Study of the Liver criteria were included during 8 years. Liver biopsies from 98 patients with compensated chronic liver disease were included as disease controls for histologic comparison. Features of ongoing changes, such as hepatic necrosis, hepatic apoptosis, cholestasis, hepatocyte degeneration, bile ductular proliferation, Mallory-Denk bodies, steatosis, and extent of liver fibrosis, were analyzed for predicting short-term mortality (28 days). A P value of <.05 was considered significant. RESULTS.­: In our cohort of ACLF patients, the following etiologies for acute decompensation were identified: alcohol, 47 of 152 (30.9%); sepsis, 24 of 152 (15.7%); hepatotropic viruses, 20 of 152 (13.1%); drug-induced liver injury, 11 of 152 (7.2%); autoimmune flare, 9 of 152 (5.9%); mixed etiologies, 5 of 152 (3.2%); and cryptogenic, 36 of 152 (23.6%). On histologic examination, hepatic necrosis (P < .001), dense lobular inflammation (P = .03), cholestasis (P < .001), ductular reaction (P = .001), hepatocyte degeneration (P < .001), and absence of advanced fibrosis stages (P < .001) were identified significantly more othen in ACLF patients than in disease controls on univariate analysis. On multivariate Cox regression analysis, the absence of advanced Ishak histologic activity index fibrosis stages (P = .02) and the presence of dense lobular inflammation (P = .04) were associated with increased 28-day mortality in ACLF patients. After adjusting the clinical causes of acute decompensation, only dense lobular inflammation was found as an independent predictor of short-term mortality (P = .04) in ACLF patients. CONCLUSIONS.­: Dense lobular necroinflammatory activity is a clinically independent histologic predictor of 28-day short-term mortality in patients with ACLF.

Antituberculosis therapy-induced acute liver failure: magnitude, profile, prognosis, and predictors of outcome.

UNLABELLED: Antituberculosis therapy (ATT)-associated acute liver failure (ATT-ALF) is the commonest drug-induced ALF in South Asia. Prospective studies on ATT-ALF are lacking. The current study prospectively evaluated the magnitude, clinical course, outcome, and prognostic factors in ATT-ALF. From January 1986 to January 2009, 1223 consecutive ALF patients were evaluated: ATT alone was the cause in 70 (5.7%) patients. Another 15 (1.2%) had ATT and simultaneous hepatitis virus infection. In 44 (62.8%) patients, ATT was prescribed empirically without definitive evidence of tuberculosis. ATT-ALF patients were younger (32.87 [+/-15.8] years), and 49 (70%) of them were women. Most had hyperacute presentation; the median icterus encephalopathy interval was 4.5 (0-30) days. The median duration of ATT before ALF was 30 (7-350) days. At presentation, advanced encephalopathy and cerebral edema were present in 51 (76%) and 29 (41.4%) patients, respectively. Gastrointestinal bleed, seizures, infection, and acute renal failure were documented in seven (10%), five (7.1%), 26 (37.1%), and seven (10%) patients, respectively. Compared with hepatitis E virus (HEV) and non-A non-E-induced ALF, ATT-ALF patients had nearly similar presentations except for older age and less elevation of liver enzymes. The mortality rate among patients with ATT-ALF was high (67.1%, n = 47), and only 23 (32.9%) patients recovered with medical treatment. In multivariate analysis, three factors independently predicted mortality: serum bilirubin (>or=10.8 mg/dL), prothrombin time (PT) prolongation (>or=26 seconds), and grade III/IV encephalopathy at presentation. CONCLUSION: ATT-ALF constituted 5.7% of ALF at our center and had a high mortality rate. Because the mortality rate is so high, determining which factors are predictors is less important. A high proportion of patients had consumed ATT empirically, which could have been prevented.
