Endoscopic glue injection versus glue plus BRTO or TIPSS for preventing gastric variceal bleeding: A randomized controlled trial.

BACKGROUND AND AIMS: To compare the efficacy of endoscopic injection sclerotherapy with N-butyl cyanoacrylate glue (EIS-CYA) vs EIS-CYA plus a radiologic intervention (either transjugular intrahepatic portosystemic shunt (TIPSS) or balloon-occluded retrograde transvenous obliteration (BRTO)) for secondary prophylaxis in patients with liver cirrhosis who presented with acute variceal bleeding (AVB) from cardiofundal varices. Primary outcome measure was gastric varix (GV) rebleed rates at 1 year. METHODS: Consecutive cirrhosis patients with AVB from cardiofundal varices were randomized into two arms (45 in each) after primary hemostasis by EIS-CYA. In the 'endoscopic intervention' (EI) arm, EIS-CYA was repeated at regular intervals (1, 3, 6 and 12 months), while in the 'radiological intervention' (RI) arm, patients underwent TIPSS or BRTO followed by endoscopic surveillance. RESULTS: GV rebleed rates at 1 year were higher in the EI arm compared to the RI arm: 11 (24·4%; 95% CI: 12·9%-39·5%) versus 1 (2·2%; 95% CI: 0·1%-11·8%); (p=0·004) [ARD: 22.2% (95% CI: 8.4%-36.6%)]. GV rebleed related mortality in the EI arm [8 (17·8%; 95% CI: 8·0%-32·1%)] was significantly higher than in the RI arm [1 (2·2%; 0·1%-11·8%)] (p=0.030) [ARD: 15.6 (95% CI: 2.9%-29.2%)], however, there was no difference in all-cause mortality between the two groups (12 [26·7%; 95% CI: 14·6 to 41·9] versus 7 [15·6%; 95% CI: 6·5 to 29·5]). Numbers needed to treat (NNT) to prevent one GV-related rebleed at 1 year was 4.5. CONCLUSION: Radiological intervention for secondary prophylaxis reduces rebleeding from gastric varices and GV rebleeding related mortality in patients with gastric variceal hemorrhage.

Definitions, Etiologies, and Outcomes of Acute on Chronic Liver Failure: A Systematic Review and Meta-analysis.

BACKGROUND & AIMS: Acute-on-chronic liver failure (ACLF) is a major public health concern. We aimed to assess the definitions, etiologic spectrum, organ failure (OF), and outcomes of ACLF globally. METHODS: Three databases were searched for studies on ACLF from 1990 until September 2022. Information regarding definitions, acute precipitants, underlying chronic liver disease (CLD), OF, and mortality were extracted. Meta-analyses were performed for pooled prevalence rates (95% confidence interval [CI]) using random-effects model for each definition of ACLF. RESULTS: Of the 11,451 studies identified, 114 articles (142 cohorts encompassing 210,239 patients) met the eligibility criteria. Most studies (53.2%) used the European Association for the Study of the Liver (EASL) definition, followed by Asia-Pacific Association for the Study of the Liver (APASL) (33.3%). Systemic infection was the major acute precipitant, and alcohol use was the major cause of CLD in EASL-defined studies, whereas alcohol was both the major acute precipitant and cause of CLD in APASL-defined studies. Liver failure was the major OF in APASL-based studies, whereas renal failure was predominant in EASL-based studies. Thirty-day mortality varied across definitions: APASL: 38.9%, 95% CI, 31.2%-46.9%; EASL: 47.9%, 95% CI, 42.2%-53.5%; and NACSELD: 52.2%, 95% CI, 51.9%-52.5%. Diagnostic overlap between definitions ranged from 7.7% to 80.2%. Meta-regression suggested that the World Health Organization region influenced 30-day mortality in studies using EASL definition. CONCLUSIONS: Heterogeneity in the definition of ACLF proposed by different expert societies and regional preferences in its use result in differences in clinical phenotype and outcomes. A uniform definition would enhance the comparability and interpretation of global data.

Thromboelastography-guided vs. standard-of-care or on-demand platelet transfusion in patients with cirrhosis and thrombocytopenia undergoing procedures: A randomized controlled trial.

PURPOSE: To compare the efficacy and safety of a thromboelastography (TEG)-guided platelet transfusion strategy to empirical or on-demand transfusions in patients with cirrhosis and severe thrombocytopenia (platelet counts <50 x109/L) undergoing high-risk invasive procedures. MATERIALS AND METHODS: This was a single-center, single-blinded, randomized controlled trial. Patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures were randomized into three groups- TEG group: transfusions based on TEG parameters; SOC group: 3 units of random donor platelets pre-procedure; On-demand group: transfusions based on procedural adverse effects /clinician's discretion. The primary outcome was periprocedural platelet transfusion in each arm. RESULTS: Eighty-seven patients were randomized (29 in each group) with no significant differences in demographics/coagulation profile/procedures. The median platelet count was 33 x109/L (IQR: 26-43). Percutaneous liver biopsy was the most common procedure (46, 52.9%). Significantly lower number of patients in the TEG group received platelets (4 cases, 13.8%; 95%CI: 3.9-31.7) compared to SOC (100%; 95%CI: 88.1-100) (p<0.001). Four patients in the on-demand group received platelets (13.8%; 95%CI: 3.9-31.7). Minor (WHO grade 2) procedure-related bleeding occurred in 3 (10%; 95%CI: 2.2-27.4) patients in the TEG-guided transfusion group, compared to 1 (3.4%; 95%CI: 0.1-17.8) each in SOC and on-demand groups, respectively (p=0.43) although our sample size was underpowered for comparison of outcomes such as post-procedural bleeding. No bleeding-related mortality was observed in any of the three groups. CONCLUSION: Thromboelastography-guided transfusion reduces prophylactic transfusions in patients with cirrhosis and severe thrombocytopenia undergoing high-risk invasive procedures.

We describe a rare occurrence of bilateral acute severe sensorineural hearing loss in a middle-aged man that heralded the diagnosis of metastatic gastric cancer.

Compensated Advanced Chronic Liver Disease in Nonalcoholic Fatty Liver Disease: Two-Step Strategy is Better than Baveno Criteria.

BACKGROUND: Advanced fibrosis and cirrhosis (compensated advanced chronic liver disease [cACLD]) are clinically indistinguishable and increase risk of developing clinically significant portal hypertension. Baveno VII recommends using elastography to rule out and diagnose cACLD with liver stiffness measurement (LSM) cut-offs of 10/15 kPa. METHODS: In a retrospective analysis of 330 nonalcoholic fatty liver disease (NAFLD) patients, performance of the Baveno VII cut-offs for diagnosing cACLD was compared with newly suggested lower cut-offs (8/12 kPa). A model for detecting cACLD among those with LSM between 8 and 12 kPa was developed and compared with recently published models. RESULTS: Seventy (21.2%) of the 330 NAFLD patients had biopsy-proven cACLD. The Baveno VII cut-offs (10/15 kPa) had a lower sensitivity of 72.8% (60.9-82.8%) and a specificity of 93.4% (89.7-96.1%). Sensitivity and specificity of lower cut-offs (8/12 kPa) were 91.4% (82.3-96.8%) and 88.5% (83.9-92.1%), respectively. Modeling based on the presence of diabetes (odds ratio [OR] 3.625[1.161-11.320], p = 0.027) and serum aspartate aminotransferase (AST) levels (OR 1.636[1.098-2.436], p = 0.015) correctly identified 75.7% of patients with LSM between 8 and 12 kPa. Our model performed best with an area under receiver operator curve (AUROC) of 0.725 (95%CI 0.609-0.822), compared to Papatheodoridi (AUROC 0.626, CI 0.506-.736) and Zhou (AUROC 0.523, CI 0.403-0.640) models. A two-step strategy comprising application of lower LSM cut-offs followed by the predictive model correctly identified the presence of cACLD in 83% of the patients as compared to 75% by the Baveno VII cut-offs. CONCLUSION: A two-step strategy employing lower LSM cut-offs and modeling based on diabetes and AST levels outperforms Baveno VII cut-offs for identifying cACLD in NAFLD patients.

Poor Performance of Non-invasive Tests for Advanced Fibrosis in Nonalcoholic Fatty Liver Disease: A Multicentric Asian Study.

BACKGROUND: Non-invasive tests (NITs) are useful to assess advanced fibrosis (AF) in nonalcoholic fatty liver disease (NAFLD). Data from Asian countries suggest that these tests have poor performance. We aimed to assess diagnostic accuracy of established thresholds of biomarker-based NITs and Transient Elastography (TE) in identifying AF and evaluated the utility of a two-step test approach. METHODS: Biopsy-proven 641 NAFLD patients (55.2% males, median age 42 years) were included from three different centers of Asia. AF (≥ F3) was identified as per histological staging (24.8%). RESULTS: TE had the highest area under the receiver operating characteristic curve (AUROC) 0.82 (0.79-0.86), and all other biomarker-based NITs had low AUROC (< 0.7). NITs performed poorly at established thresholds. The combination of NITs utilizing liver stiffness measurement (LSM) and biomarkers, Agile 3+ and FAST, demonstrated acceptable diagnostic accuracy (AUROC 0.82 and 0.78, respectively), but none were superior to LSM alone. LSM measured using appropriate M and XL probes remained accurate regardless of body mass index (BMI); NFS and APRI scores were less accurate at higher BMI ranges. A two-step approach using NFS rule-out criteria (< - 2.97 to rule out) followed by LSM (< 7.3 kPa to rule out and ≥ 12.7 kPa to rule in) correctly classified 62.4% of patients, with only 10.2% of patients incorrectly classified. CONCLUSION: NITs have not been validated to identify AF in the Asian NAFLD population, and internationally accepted thresholds yield high false-negative rates. LSM and LSM-based combination tests remain the most accurate.

Therapeutic plasma-exchange improves short-term, but not long-term, outcomes in patients with acute-on-chronic liver failure: A propensity score-matched analysis.

BACKGROUND: Acute-on-chronic liver failure (ACLF) is associated with a high short-term mortality rate in the absence of liver transplantation. The role of therapeutic plasma exchange (TPE) in improving the outcomes of ACLF and acute decompensation (AD) is unclear. In this retrospective analysis, we aimed to determine the impact of TPE on mortality in patients with ACLF. METHODS: ACLF patients receiving TPE with standard medical treatment (SMT) were propensity score matched (PSM) with those receiving SMT alone (1:1) for sex, grades of ACLF, CLIF C ACLF scores, and the presence of hepatic encephalopathy. The primary outcomes assessed were mortality at 30 and 90 days. Survival analysis was performed using Kaplan Meier survival curves. RESULTS: A total of 1151 patients (ACLF n = 864 [75%], AD [without organ failure] n = 287 [25%]) were included. Of the patients with ACLF (n = 864), grade 1, 2, and 3 ACLF was present in 167 (19.3%), 325 (37.6%), and 372 (43.0%) patients, respectively. Thirty-nine patients received TPE and SMT, and 1112 patients received only SMT. On PSM analysis, there were 38 patients in each group (SMT plus TPE vs SMT alone). In the matched cohort, the 30-days mortality was lower in the TPE arm compared to SMT (21% vs 50%, P = .008), however, the 90-day mortality was not significantly different between the two groups (36.8% vs 52.6%, P = .166); HR, 0.82 (0.44-1.52), P = .549. CONCLUSION: TPE improves short-term survival in patients with ACLF, but has no significant impact on long-term outcomes. Randomized control trials are needed to obtain a robust conclusion in this regard.

Impact of body mass index on disease progression and outcomes in patients with nonalcoholic fatty liver disease.

BACKGROUND: The relationship between body mass index (BMI) and outcomes in patients with nonalcoholic fatty liver disease (NAFLD) is not well defined. This study aimed to assess the presentations, outcomes, and development of liver-related events (LREs) and non-LREs in patients with NAFLD stratified by BMI. METHODS: Records of NAFLD patients from 2000-2022 were reviewed. Patients were categorized as lean (18.5-22.9 kg/m2), overweight (23-24.9 kg/m2), and obese (>25 kg/m2) based on BMI. Stage of steatosis, fibrosis, and NAFLD activity score were noted in the patients undergoing liver biopsy in each group. RESULTS: Out of 1051 NAFLD patients, 127 (12.1%) had normal BMI, 177 (16.8%) and 747 (71.1%) were overweight and obese, respectively. Median [interquartile range] BMI was 21.9 [20.6-22.5], 24.2 [23.7-24.6], and 28.3 [26.6-30.6] kg/m2 in each group, respectively. Prevalence of metabolic syndrome and dyslipidemia were significantly higher in the obese. Obese patients had significantly higher median [interquartile range] liver stiffness (6.4 [4.9-9.4] kPa) than overweight and lean subjects. A higher proportion of obese patients had significant and advanced liver fibrosis. At follow-up, there were no significant differences in the progression of liver disease, new LREs, coronary artery disease, or hypertension across the BMI groups. Overweight and obese patients were more likely to develop new-onset diabetes by follow-up. The mortality rates in the three groups were comparable (0.47, 0.68, and 0.49 per 100 person-years, respectively), with similar causes of death (liver-related vs non-liver-related). CONCLUSIONS: Patients with lean NAFLD have similar disease severity and rates of progression as the obese. BMI is not a reliable determinant of outcomes in NAFLD patients.

Pancreatic hemorrhage contributes to late mortality in patients with acute necrotizing pancreatitis.

OBJECTIVES: The frequency, risk factors, and impact on survival of hemorrhage into (peri)pancreatic collections in patients with acute pancreatitis (AP) has not been well studied. The study was designed to evaluate the risk factors for hemorrhage, successful hemostasis and its effect on in-hospital mortality. METHODS: In a prospective cohort study for prediction of severity of AP, the incidence, risk factors, and outcomes of pancreatic hemorrhage were analyzed. Patients with significant hemorrhage were managed according to a predefined protocol including endovascular intervention. RESULTS: Out of 363 patients hospitalized during the study-period, 33(9%) patients developed hemorrhage. Median time from onset of AP to hemorrhage was 59(45-68) days. The cause of hemorrhage was arterial in 19(57.5%) patients and unlocalized in 14(42.5%) patients. Hemorrhage was managed by conservative approach in 7 (21.2%), radiographic angioembolisation in 16 (48.5%), radiographic angioembolisation followed by surgery in 3 (9.1%), and surgery in 7 (21.2%) patients. Persistent organ failure [aHR 2.3 (1.1-5.1), p = 0.03], use of large bore (>20 Fr) catheter for initial drainage [aHR 3.9 (1.7-9.1), p = 0.001] and extensive (>50%) necrosis [aHR 3.1 (1.4-6.9), p = 0.005] were significant risk factors for hemorrhage. Hemorrhage was an independent predictor of mortality [aHR 2.0 (1.2-3.4), p = 0.008] in addition to persistent organ failure (aHR 12.1 (5.7-25.8), p < 0.001). In-hospital mortality in patients with hemorrhage was 22/33 (66.7%) vs. 81/330 (25%) in no hemorrhage group [p <0.001]. CONCLUSION: Pancreatic hemorrhage occurs later in the course of acute pancreatitis in relatively sicker group of patients with organ failure and extensive necrosis, and is independently associated with a higher risk of in-hospital mortality.

Virus related acute pancreatitis and virus superinfection in the 'Dual disease' model of acute pancreatitis and SARS-Co-V2 infection: A multicentre prospective study.

BACKGROUND: SARS-CoV-2 can cause acute pancreatitis (AP) and SARS-CoV-2 superinfection can occur in patients with AP during prolonged hospitalisation. Our objective was to characterize SARS-CoV-2 related AP and study the impact of SARS-CoV-2 superinfection on outcomes in AP. METHODS: In this multicentre prospective study, all patients with AP and SARS-CoV-2 infection between August 2020 and February 2021 were divided into two groups: SARS-CoV-2-related AP and superadded SARS-CoV-2 infection in patients with AP. The two groups were compared with each other and the whole cohort was compared with a non-COVID AP cohort. RESULTS: A total of 85 patients with SARS-CoV-2 and AP (SARS-CoV-2-related AP; n = 18 and AP with SARS-CoV-2 superadded infection; n = 67) were included during the study period. They had a higher mortality [28 (32.9%) vs. 44 (19.1%), aOR 2.8 (95% CI, 1.5-5.3)] than 230 propensity matched non-COVID AP patients. Mortality in SARS-CoV-2 and AP patients was due to critical COVID. SARS-CoV-2-related- AP (n = 18) had a higher but statistically insignificant mortality than SARS-CoV-2 superinfection in AP [8/18 (44.4%) vs 20/67 (29.8%), p = 0.24]. On multivariable analysis, infection with SARS-CoV-2 (aHR 2.3; 95% CI, 1.43.7) was a predictor of in-hospital mortality in addition to organ failure (OF) in patients with AP. CONCLUSION: Patients with AP and SARS-CoV-2 infection had a higher mortality than matched non-COVID AP patients which was largely attributable to the severity of COVID-19. SARS-CoV-2 related AP had higher OF and in-hospital mortality.

Clinical Utility of Transient Elastography in the Management of Patients with Budd-Chiari Syndrome Undergoing Endovascular Intervention.

PURPOSE: To quantify liver stiffness measurement (LSM) changes after endovascular intervention for Budd-Chiari syndrome (BCS) and evaluate whether LSM changes predict restenosis after endovascular intervention. MATERIALS AND METHODS: Patients with BCS who underwent endovascular intervention and had at least 2 LSM values available after the intervention were included. ΔLSM was the difference between LSMs estimated at the last and second last hospital visits. In patients with restenosis, 2 LSM values before restenosis were included. ΔLSM% was calculated as the ratio of ΔLSM to the LSM at the second last visit and expressed as a percentage. Odds ratio (OR) with confidence interval (CI) and area under the receiver operating characteristic curves (AUROCs) were calculated for the predictors of restenosis. RESULTS: The median baseline and postinterventional 1-week, 3-month, 6-month, and 12-month LSM values were 47.2 kPa (33.8-68.4 kPa), 29.2 kPa (24.5-43.0 kPa), 26.2 kPa (18.6-38.9 kPa), 20.9 kPa (13.3-29.8 kPa), and 17.3 kPa (11.8-25.4 kPa), respectively. Of the 118 patients, including 67 men, restenosis developed in 10 patients after a median (interquartile range) duration of 19 months (11-46 months). ΔLSM% was higher (more positive) in patients with restenosis than in those without restenosis (44.7 [8.3-134.3] vs -6.6 [-19.4 to 14.9], P = .001). ΔLSM% was a significant predictor of restenosis with an OR of 1.032 (95% CI, 1.015-1.050; P < .001). The AUROC for ΔLSM% was 0.831 (95% CI, 0.750-0.893; P = .001), and a ΔLSM% increment of 13.2% predicted restenosis with a sensitivity and specificity of 80.0% and 74.1%, respectively. CONCLUSIONS: LSM gradually decreases after endovascular intervention, and transient elastography is a promising test for detecting restenosis after the endovascular treatment of patients with BCS.

Clinical Course of Chronic Pancreatitis During Pregnancy and its Effect on Maternal and Fetal Outcomes.

INTRODUCTION: There are limited data on the effect of chronic pancreatitis (CP) on pregnancy outcomes and vice versa. Our aim was to evaluate the clinical trajectory of CP during pregnancy and its effect on pregnancy outcomes. METHODS: All female patients of child-bearing age (≥15 years) diagnosed with CP were studied from January 2004 to July 2019. The change in frequency of painful episodes was assessed before, during, and after pregnancy. Maternal and fetal outcomes were compared between pregnant women (early onset) and women presenting with CP after completion of all pregnancies (late onset). RESULTS: Of 187 women with CP, pregnancy outcomes and clinical course were assessed in 99 patients. The frequency of painful exacerbations was significantly lower during pregnancy compared with prepregnancy and postpregnancy periods (P < 0.001). The median pain score decreased significantly to 0 (0-2) during pregnancy from 3 (0-6) before conception and increased to 4 (0-8) after pregnancy (P = 0.002). Women with early onset CP (n = 57) had their first child later and had fewer pregnancies compared with those with late onset CP (n = 42). There was no difference in maternal outcomes such as gestational diabetes, hypertension, and preterm delivery, and fetal outcomes such as abortion, low birth weight, and still birth between the groups. There was no reported congenital anomaly. DISCUSSION: Younger patients with CP had later and fewer pregnancies, but there was no increased risk of adverse maternal and fetal outcomes. The clinical course of CP was usually benign during pregnancy with decreased frequency and severity of pain.

Real-world re-treatment outcomes of direct-acting antiviral therapy failure in patients with chronic hepatitis C.

Direct-acting antiviral (DAA) drugs are associated with high (>95%) sustained virological response at 12 weeks (SVR12) in chronic hepatitis C (CHC) patients. There is a paucity of data regarding the characteristics and re-treatment outcomes of DAA treatment failure patients. In a retrospective analysis of the prospectively collected database, we assessed the outcomes of re-treatment among patients with previous DAA failure. Patients' characteristics, viral characteristics, including resistance-associated substitutions (RAS) in a subgroup of patients, SVR12, and clinical outcomes were studied. Of 40 patients with DAA failure, among whom 36 were retreated, mean age was 45.7 years, 63.9% (n = 23) were male, 63.9% (n = 23) had a genotype-3 infection and 63.9% (n = 23) were cirrhotic. The re-treatment regimens included a combination of pan-genotypic DAA, mainly sofosbuvir and velpatasvir with or without ribavirin. Three patients who declined retreatment and one who was still on treatment was excluded. For patients who completed re-treatment, SVR12 was 100% irrespective of genotypes. SVR12 among genotype 3 was 75% (15 of 20) when lost to follow-up was considered a treatment failure. Six patients died due to liver-related causes, including five (83.3%) with hepatocellular carcinoma. RAS analysis in 17 randomly selected patients did not reveal any dominant substitutions in NS5A or NS5B region affecting SVR12, though several novel mutations were observed. In conclusion, re-treatment of CHC patients with prior DAA failure using pan-genotypic DAA is associated with high SVR12 rates irrespective of genotype or the presence of RAS.

Endoscopic transmural drainage tailored to quantity of necrotic debris versus laparoscopic transmural internal drainage for walled-off necrosis in acute pancreatitis: A randomized controlled trial.

BACKGROUND AND AIMS: Both endoscopic and laparoscopic transmural internal drainage are practiced for drainage of walled-off necrosis (WON) following acute pancreatitis (AP) but the superiority of either is not established. Our aim was to compare transperitoneal laparoscopic drainage with endoscopic drainage using either lumen apposing metal stents (LAMS) or plastic stents tailored to the amount of necrotic debris in WON. METHODS: In a randomized controlled trial, adequately powered to exclude the null hypothesis, patients with symptomatic WON were randomized to either endoscopic or laparoscopic drainage. In the endoscopy group, two plastic stents were placed if the WON contained <1/3rd necrotic debris and a LAMS was placed if it was >1/3rd. Primary outcome was resolution of WON within 4 weeks without re-intervention for secondary infection. Secondary outcome was overall success (resolution of WON at 6 months) and adverse events. RESULTS: Forty patients were randomized: 20 to each group. Baseline characteristics were comparable between the groups. Primary outcome was similar between the groups [16 (80%) in laparoscopy and 15 (75%) in endoscopy group; p = 0.89]. The overall success was similar [18 (90%) in laparoscopy vs. 17 (85%) in endoscopy; p = 0.9]. Median duration of hospital stay was shorter in endoscopy group [4 (4-8) vs. 6 days (5-9); p = 0.03]. Adverse events were comparable between the groups. CONCLUSION: Laparoscopic drainage was not superior to endoscopic transmural drainage with placement of multiple plastic stent or LAMS depending on the amount of necrotic debris for symptomatic WON in AP. The hospital stay was shorter with the endoscopic approach.

FibroScan-aspartate aminotransferase score in an Asian cohort of non-alcoholic fatty liver disease and its utility in predicting histological resolution with bariatric surgery.

BACKGROUND AND AIM: The FibroScan-aspartate aminotransferase (FAST) score was developed for identifying patients with non-alcoholic steatohepatitis, who also have an elevated non-alcoholic fatty liver disease (NAFLD) activity score (NAS) ≥ 4 and significant fibrosis (F ≥ 2). We aimed to validate it in our NAFLD cohort and assess if it correlates with the histological changes after bariatric surgery. METHODS: Patients with NAFLD, including those undergoing bariatric surgery, were included. The FAST score was calculated using liver stiffness measure, controlled attenuation parameter, and aspartate aminotransferase. Calibration and discrimination of the model were assessed by calibration plots and area under the receiver operating characteristic curve, respectively. Sensitivity and specificity were assessed at the rule-out and rule-in cutoffs (≤0.35 and ≥0.67), respectively. Changes in the NAS and FAST scores were compared in the bariatric cohort 1 year after surgery. RESULTS: The cohort composed of 309 patients, of which 48 patients underwent repeat liver biopsy at 1 year. The model showed good discrimination with area under the receiver operating characteristic curve of 0.79 (0.74-0.84); however, it was not satisfactorily calibrated (Hosmer-Lemeshow test, P = 0.008). The sensitivity and specificity at the rule-out and rule-in cutoffs were 0.90 and 0.84, respectively. A significant correlation was seen between the 1-year reduction in the NAS and FAST scores (r = 0.38, P = 0.009). A significant reduction in the median FAST score was seen in patients who had ≥2-point reduction in NAS after bariatric surgery. CONCLUSION: FibroScan-aspartate aminotransferase score demonstrated good discrimination for fibrotic non-alcoholic steatohepatitis in our cohort. However, a miscalibration resulted in overprediction. The score correlated well with the histological response to interventions for NAFLD.

Acute pancreatitis and nosocomial COVID-19: Cause specific host responses may determine lung injury.

BACKGROUND: Coronavirus disease 2019 (COVID-19) presents with myriad extra-pulmonary manifestation and a high mortality in patients with comorbidities. Its effect on patients with pre-existing acute pancreatitis is not known. METHODS: We hereby, present 3 cases with severe acute pancreatitis with persistent respiratory failure who acquired nosocomial COVID-19 during their hospital stay after recovery from respiratory failure. Their clinical course is highlighted which reflects on pathophysiology of organ dysfunction in these 2 disease states. RESULTS: None of the 3 patients with severe acute pancreatitis who developed nosocomial COVID-19 redeveloped respiratory failure due to COVID-19 despite having recently recovered from pancreatitis induced acute hypoxemic respiratory failure. Only one patient developed SARS-CoV2 induced moderate pneumonia. CONCLUSION: These cases highlight that host responses and mechanisms of lung injury might be different in severe acute pancreatitis and COVID-19.

Acute-on-Chronic Liver Failure in Budd-Chiari Syndrome: Profile and Predictors of Outcome.

BACKGROUND AND AIM: There is a paucity of data on the clinical presentations and outcome of Budd-Chiari syndrome (BCS) patients presenting as acute-on-chronic liver failure (BCS-ACLF). We aimed to describe the profile and outcomes of endovascular interventions in patients with BCS-ACLF. METHODS: All BCS-ACLF patients presenting between October 2007 and April 2019 satisfying the Asian Pacific Association for the Study of the Liver (APASL) definition were studied. We compared 30- , 90- and, 180-day survival among BCS-ACLF patients who underwent endovascular intervention with those who did not, and with a historical cohort of Child-C BCS patients without ACLF who underwent endovascular intervention. RESULTS: Twenty-eight (5%) of 553 BCS patients presented as ACLF as per APASL definition. The majority (60.7%) were males, and mean age was 29.6 ± 11.2 years. The most common site of the block was isolated involvement of hepatic veins-HV (68%), followed by combined inferior vena cava (IVC) and HV block (25%) and isolated IVC block (7%). The acute precipitants were stent thrombosis (17.9%), acute HV thrombosis (10.7%), acute viral hepatitis (7.1%), and antituberculosis drug with hepatitis B virus reactivation (3.6%). In 60.7% patients, no acute precipitant could be identified. The 30- , 90- , and 180-day survival in BCS-ACLF post-endovascular intervention (n = 15), BCS-ACLF without endovascular intervention (n = 13), and Child-C BCS without ACLF who underwent endovascular intervention (n = 25) were (93%, 87%, and 87%), (46%, 28%, and 0%) and (96%, 92%, and 88%), respectively (log-rank test, p value < 0.001). On multivariate Cox proportional analysis, endovascular intervention and the presence of hepatic encephalopathy were independent predictors of mortality. CONCLUSION: Budd-Chiari syndrome can present as acute-on-chronic liver failure. Endovascular intervention is associated with an improved outcome.
