Patients With Compensated Hepatitis B Virus-Related Cirrhosis and Low-Level Viremia: Treat or Not to Treat?

ABSTRACT: Patients with hepatitis B virus-related cirrhosis and low-level viremia represent a special group that might benefit from treatment because of their higher risk of complications. Evidence for the benefit of treatment in this population is lacking. The current study, which analyzed data of a historical cohort of 627 patients from a single Korean center with hepatitis B virus-related compensated cirrhosis, reported a 2.4-fold increased hepatocellular carcinoma risk among patients with low-level viremia compared with those with undetectable viremia provides indirect evidence in support of treatment for this population. The study underscores the importance of treating patients before the development of cirrhosis and the need for finite duration curative therapy.

Controlling the Balance between Remote, Pinhole, and van der Waals Epitaxy of Heusler Films on Graphene/Sapphire.

Remote epitaxy is promising for the synthesis of lattice-mismatched materials, exfoliation of membranes, and reuse of expensive substrates. However, clear experimental evidence of a remote mechanism remains elusive. Alternative mechanisms such as pinhole-seeded epitaxy or van der Waals epitaxy can often explain the resulting films. Here, we show that growth of the Heusler compound GdPtSb on clean graphene/sapphire produces a 30° rotated (R30) superstructure that cannot be explained by pinhole epitaxy. With decreasing temperature, the fraction of this R30 domain increases, compared to the direct epitaxial R0 domain, which can be explained by a competition between remote versus pinhole epitaxy. Careful graphene/substrate annealing and consideration of the relative lattice mismatches are required to obtain epitaxy to the underlying substrate across a series of other Heusler films, including LaPtSb and GdAuGe. The R30 superstructure provides a possible experimental fingerprint of remote epitaxy, since it is inconsistent with the leading alternative mechanisms.

Breathability and Safety Testing of Personal Protective Equipment: "Human-comfort" Factor Remains Undefined.

Healthcare systems all over the world have been enormously affected by the COVID-19 pandemic. Healthcare workers (HCWs) taking care of these patients need personal protective equipments (PPEs) standardized for full protection from droplets and aerosols carrying viral load to variable distances. There has been a surge of manufacturers supplying these protective gears in India and regulatory agencies have issued technical specifications pertaining to PPEs focusing solely on synthetic blood penetration tests (SBPTs) and keeping the upper limit of non-woven fabric to 95 g/m2 (GSM). These PPE specifications are silent on air permeability (AP) and water/moisture vapor transmission rate (WVTR/MVTR) of the fabric. As a result, most of the PPE kits, despite having appropriate SBPT certifications from regulatory agencies, have extremely poor permeability and breathability. The acceptability of PPEs by HCWs can be vastly improved when the end-users are proactively invited to participate in "comfort testing" of PPEs before getting issuance of certification for marketing. "Field testing" or "end-user trials" in which HCWs don the PPE and assess it for comfort while performing different types of clinical work, e.g., in intensive care units (ICUs), operation theaters, cath labs, etc., also takes into account a hitherto often ignored "human-comfort-factor" that not only enhances the understanding of HCWs about the need for the PPEs but can also motivate them to use it without worrying about discomfort. We hereby propose that comfort fit testing (COmfort and Material Fit is an Obviously Required Test) should be a part of the mandatory testing and certification process for PPE, so that the industry invests wisely in manufacturing PPE kits that are not only certified for fabric but are also tested for comfort factors.

Childhood pancreatic trauma: Clinical presentation, natural history and outcome.

OBJECTIVES: To study the presentation, management strategies and long-term natural history of children with pancreatic trauma. METHODS: Children admitted with pancreatic trauma were analyzed for their presentation, management and outcome. Management included nasojejunal feeds, total parenteral nutrition (TPN), octreotide, drainage (radiological and endoscopic), endoscopic retrograde cholangiopancreatography (ERCP) and surgery. Patients were assessed in follow-up for development of chronic pancreatitis (CP). RESULTS: 36 children [29 boys, age 144 (13-194) months] presented at 30 (3-210) days after trauma. Most common cause of trauma was bicycle handle bar injury [n = 18,50%]. Presenting features were abdominal pain [n = 26,72%], lump [n = 16, 44.4%], ascites [n = 13,36%], pleural effusion [n = 9,25%] and anasarca [n = 3,8.3%]. All presented with sequelae of ductal disruption with pseudocyst, ascites or pleural effusion. Fifteen (41.6%) patients each had Grade III and IV injury, 4 (11%) had grade V, and grading was unavailable in 2. Other organs were injured in 4 (11%) cases. Management consisted of various combinations of nasojejunal feeds [n = 17,47.2%], TPN [n = 5,13.8%], octreotide [n = 13,36%], pseudocyst drainage [radiological (n = 18,50%), endoscopic (n = 3,8.3%)] and ERCP [n = 12,33.3%]. Surgical intervention was done in 2 (5.5%) cases [cystojejunostomy and peritoneal lavage in 1 each]. Two (5.5%) patients died due to sepsis. Of the 32 cases in follow-up, 19 (59.3%) recovered and 13 (40.6%) developed CP, with half (6/13) of them being symptomatic with recurrent pain. CONCLUSION: Multi-disciplinary non-operative management is effective for managing pancreatic trauma in 94.4% of children, with 75% requiring radiological or endoscopic intervention. 40% developed structural changes later but only half were symptomatic.

Utility and accuracy of transient elastography in determining liver fibrosis: a case-control study.

The objectives of this prospective case-control study were to determine liver stiffness (LSM) by transient elastography (TE) in children with newly diagnosed chronic liver disease (CLD) and to find out normal values in healthy Indian children. Two groups (A: 50 CLD who underwent liver biopsy and B: 50 healthy) aged 5-18 years were recruited prospectively. Liver biopsies were scored as per Metavir scoring and compared with TE. The median age of 100 recruited children was 13.6 years. In group B, normal LSM was 4.9 (2.5-7.3) kPa with significantly higher LSM in adolescent males (5.6 (4.1-7.3) kPa) as compared with females (4.3 (3.7-4.9) kPa), p = 0.001. In group A, TE was excellent in discriminating significant fibrosis (≥ F2) (P = 0.001) at a cut-off value of 10.6 kPa with area under receiver operating characteristic curve of 0.96. Metavir fibrosis stage (ß = 0.611; R2 = 0.586) and age (ß = 0.230; R2 = 0.586) were independent variables associated with higher LSM in stepwise multiple logistic regression analysis.Conclusions: TE is an excellent non-invasive tool to assess significant liver fibrosis and can be used as an alternative to liver biopsy. Normative value of TE in adolescent males is higher than in females.What is Known:• Transient elastography is a good non-invasive test for liver fibrosis assessment.• Normal liver stiffness depends on race, gender, and age.What is New:• This is the first study from India to show the normative data of transient elastography in healthy Indian children.• We have documented that liver stiffness measurement by fibroscan in treatment naïve chronic liver disease has excellent correlation in significant fibrosis, severe fibrosis, and cirrhosis.

Drug-Induced Acute-on-Chronic Liver Failure in Asian Patients.

OBJECTIVES: Acute insults from viruses, infections, or alcohol are established causes of decompensation leading to acute-on-chronic liver failure (ACLF). Information regarding drugs as triggers of ACLF is lacking. We examined data regarding drugs producing ACLF and analyzed clinical features, laboratory characteristics, outcome, and predictors of mortality in patients with drug-induced ACLF. METHODS: We identified drugs as precipitants of ACLF among prospective cohort of patients with ACLF from the Asian Pacific Association of Study of Liver (APASL) ACLF Research Consortium (AARC) database. Drugs were considered precipitants after exclusion of known causes together with a temporal association between exposure and decompensation. Outcome was defined as death from decompensation. RESULTS: Of the 3,132 patients with ACLF, drugs were implicated as a cause in 329 (10.5%, mean age 47 years, 65% men) and other nondrug causes in 2,803 (89.5%) (group B). Complementary and alternative medications (71.7%) were the commonest insult, followed by combination antituberculosis therapy drugs (27.3%). Alcoholic liver disease (28.6%), cryptogenic liver disease (25.5%), and non-alcoholic steatohepatitis (NASH) (16.7%) were common causes of underlying liver diseases. Patients with drug-induced ACLF had jaundice (100%), ascites (88%), encephalopathy (46.5%), high Model for End-Stage Liver Disease (MELD) (30.2), and Child-Turcotte-Pugh score (12.1). The overall 90-day mortality was higher in drug-induced (46.5%) than in non-drug-induced ACLF (38.8%) (P = 0.007). The Cox regression model identified arterial lactate (P < 0.001) and total bilirubin (P = 0.008) as predictors of mortality. DISCUSSION: Drugs are important identifiable causes of ACLF in Asia-Pacific countries, predominantly from complementary and alternative medications, followed by antituberculosis drugs. Encephalopathy, bilirubin, blood urea, lactate, and international normalized ratio (INR) predict mortality in drug-induced ACLF.

Polymorphism in interferon λ3/interleukin-28B gene and risk to noncirrhotic chronic hepatitis C genotype 3 virus infection and its effect on the response to combined daclatasvir and sofosbuvir therapy.

Hepatitis C virus (HCV) infection is a considerable public-health problem and an important cause of liver disease with about 71 million people infected worldwide and more than 399 000 people die every year from hepatitis C-related liver diseases. The present study was, therefore, initiated to investigate the association of polymorphism in interferon λ3 (IFNL3) also known as interleukin-28B (IL-28B) gene with chronic HCV infection and association of these polymorphic variants with the combination daclatasvir and sofosbuvir HCV therapy response. Genotypes were determined by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay in a total of 250 chronic HCV genotype three patients and 500 number of healthy controls. Our data revealed that the TT (minor) genotype of IFNL3 (rs12979860) and GG (minor) genotype of IFNL3 (rs8099917) exhibited a significant association with chronic HCV genotype 3 infection when compared with controls. The results of treatment response showed that CC (major) genotype of IFNL3 (rs12979860) and TT (major) genotype of IFNL3 (rs8099917) are associated with the likelihood of achieving a higher sustained virological response (SVR), to combined daclatasvir and sofosbuvir therapy, in genotype 3-infected HCV patients, whereas the individuals with TT (minor) genotype of IFNL3 (rs12979860) and GG (minor) genotype of IFNL3 (rs8099917) are more susceptible to chronic HCV infection and treatment relapse, suggesting a role of IFNL3 (rs12979860) and (rs8099917) in the treatment outcome of combined daclatasvir and sofosbuvir therapy in chronic HCV genotype 3 infection.

Enhancing the signal strength of surface sensitive 2D IR spectroscopy.

Spectroscopic techniques that are capable of measuring surfaces and interfaces must overcome two technical challenges: one, the low coverage of molecules at the surface, and two, discerning between signals from the bulk and surface. We present surface enhanced attenuated reflection 2D infrared (SEAR 2D IR) spectroscopy, a method that combines localized surface plasmons with a reflection pump-probe geometry to achieve monolayer sensitivity. The method is demonstrated at 6 µm with the amide I band of a model peptide, a cysteine terminated α-helical peptide tethered to a gold surface. Using SEAR 2D IR spectroscopy, the signal from this sample is enhanced 20 000-times over a monolayer on a dielectric surface. Like attenuated total reflection IR spectroscopy, SEAR 2D IR spectroscopy can be applied to strongly absorbing solvents. We demonstrated this capability by solvating a peptide monolayer with H2O, which cannot normally be used when measuring the amide I band. SEAR 2D IR spectroscopy will be advantageous for studying chemical reactions at electrochemical surfaces, interfacial charge transfer in photovoltaics, and structural changes of transmembrane proteins in lipid membranes.

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. Multivariate logistic regression model (PIRO score) was developed from a derivation cohort (n=1363) which was validated in another prospective multicentric cohort of acute on chronic liver failure patients (n=997). RESULTS: Factors significant for P component were serum creatinine[(≥2 mg/dL)OR 4.52, 95% CI (3.67-5.30)], bilirubin [(<12 mg/dL,OR 1) vs (12-30 mg/dL,OR 1.45, 95% 1.1-2.63) vs (≥30 mg/dL,OR 2.6, 95% CI 1.3-5.2)], serum potassium [(<3 mmol/LOR-1) vs (3-4.9 mmol/L,OR 2.7, 95% CI 1.05-1.97) vs (≥5 mmol/L,OR 4.34, 95% CI 1.67-11.3)] and blood urea (OR 3.73, 95% CI 2.5-5.5); for I component nephrotoxic medications (OR-9.86, 95% CI 3.2-30.8); for R component,Systemic Inflammatory Response Syndrome,(OR-2.14, 95% CI 1.4-3.3); for O component, Circulatory failure (OR-3.5, 95% CI 2.2-5.5). The PIRO score predicted acute kidney injury with C-index of 0.95 and 0.96 in the derivation and validation cohort. The increasing PIRO score was also associated with mortality (P<.001) in both the derivation and validation cohorts. CONCLUSIONS: The PIRO model identifies and stratifies acute on chronic liver failure patients at risk of developing acute kidney injury. It reliably predicts mortality in these patients, underscoring the prognostic significance of acute kidney injury in patients with acute on chronic liver failure.

Clinical profile and treatment outcome of chronic pancreatitis in children: a long-term follow-up study of 156 cases.

AIM: There is a paucity of literature in pediatric chronic pancreatitis (CP) and most information is derived from adult literature. We, therefore, analyzed our experience of CP to look for clinical profile and long-term outcome. METHODS: From January 2003 to December 2015, 156 consecutive children (≤18 years) diagnosed as CP were included. Their clinical profile, management, and follow-up data were retrieved. Genetic markers (PRSS1, SPINK1, and CFTR) were studied in 40 idiopathic cases. RESULTS: The median age of the patients was 13 [inter-quartile range (IQR): 10-14] years (93 males) and 134 (86%) were idiopathic. Genetic mutations were found in 22/40 (55%) idiopathic cases. All but two presented with pain abdomen (episodic pain in 93.6%) and symptom duration was 12 (IQR: 6-24) months. There were two subsets; calcific (CCP) 68 (43.5%) and non-calcific (NCCP) 88 (56.5%). In CCP group, significantly more children had Cambridge grade 5 magnetic resonance cholangiopancreatography changes, low weight Z-score, and had continuous pain more compared to NCCP group. Over a median follow-up of 23 (IQR: 8-45.5) months, more children in CCP group had complications. Endoscopic therapy (done for persistent pain in 40) relieved pain in 52.5% of cases while medical therapy did so in 36% of cases. CONCLUSION: Pediatric CP in Asia presents with episodic pain and genetic predisposition seems to be a major cause. There are two subsets; CCP and NCCP with former showing marked imaging changes, more often associated with malnutrition and complications. Endoscopic therapy for pain relief gives modest benefit but medical therapy is not encouraging.

NMR-based urinary profiling of lactulose/mannitol ratio used to assess the altered intestinal permeability in acute on chronic liver failure (ACLF) patients.

The article presents a simplified NMR-based protocol for urinary profiling of lactulose/mannitol ratio (LMR) and demonstrates here its utility to assess increased intestinal permeability (IP) in patients with acute on chronic liver failure (ACLF). ACLF is a serious clinical complication associated with chronic liver disease (cirrhosis). The major risk factor in its development is increased IP ('leaky gut'), which has been linked to disease progression and to infectious complications. However, IP has seldom been investigated in patients with ACLF, even though patients frequently report gastrointestinal disorders and associated complications. To this end, we first optimized the NMR-based targeted profiling of urinary metabolites (i.e. actulose, mannitol, and creatinine) and subsequently used this resulted protocol (a) first to evaluate the altered IP in ACLF patients and then (b) to explore its utility for monitoring the treatment response in these patients. The normal profiles were obtained for 7 age and sex matched healthy volunteers. The results revealed that the urinary LMR excretion was significantly higher in ACLF patients compared to normal controls (median ~0.7, range (0.12-2.84), vs median ~0.11, range (0.02-0.28), p < 0.001) suggesting that the ACLF patients' exhibit altered IP. However, the LMR excretion in six clinically improved follow-up ACLF patients was comparable to normal controls indicating restored IP after the treatment. The protocol-as demonstrated here with ACLF-is equally applicable for evaluating IP or mucosal barrier function in other intestinal disorders with reasonable sensitivity and specificity, highlighting its general utility.

Evaluation of cognitivity, proinflammatory cytokines, and brain magnetic resonance imaging in minimal hepatic encephalopathy induced by cirrhosis and extrahepatic portal vein obstruction.

BACKGROUND AND AIMS: Minimal hepatic encephalopathy (MHE) is the mildest form of hepatic encephalopathy (HE) and is characterized by deficits in neurocognitive performance without any clinical symptoms of HE. In the current study, we aim to evaluate and compare the neurocognitive, biochemical, and brain magnetic resonance (MR) imaging changes between patients with cirrhotic MHE and extrahepatic portal vein obstruction (EHPVO) MHE. METHODS: Thirty-three cirrhotic and 14 EHPVO patients were diagnosed with MHE and were included in the analysis along with 24 normal healthy volunteers. All subjects underwent MR imaging including diffusion tensor imaging and proton MR spectroscopy (1 H-MRS) followed by cognitive assessments, critical flicker frequency (CFF) measurements, quantification of blood ammonia, and serum proinflammatory cytokine levels. RESULTS: We observed abnormal neurocognitive functions and CFF measurements in both cirrhotic MHE and EHPVO MHE patients as compared with controls. Significantly increased blood ammonia, serum proinflammatory cytokines (IL-6, TNF-α) level, mean diffusivity in multiple brain sites, 1 H-MRS derived glutamate/glutamine (Glx)/creatine (Cr), and significantly decreased 1 H-MRS derived myo-inositol/Cr were observed in both cirrhotic MHE and EHPVO MHE compared with those of controls. Choline/Cr level was significantly decreased in cirrhotic MHE as compared with controls and EHPVO MHE. CONCLUSIONS: Cirrhotic MHE showed more severe changes on mean diffusivity in multiple brain sites and inflammation as compared with EHPVO MHE. This study confirms that there are significant difference in neurocognitive, biochemical, and MR profile between cirrhotic MHE and EHPVO MHE, which may help to understand the pathophysiologies of these two types of MHE and may contribute to improve their clinical managements.

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.

Reduced cortical thickness in patients with acute-on-chronic liver failure due to non-alcoholic etiology.

BACKGROUND: Acute-on-chronic liver failure (ACLF) is a form of liver disease with high short-term mortality. ACLF offers considerable potential to affect the cortical areas by significant tissue injury due to loss of neurons and other supporting cells. We measured changes in cortical thickness and metabolites profile in ACLF patients following treatment, and compared it with those of age matched healthy volunteers. METHODS: For the cortical thickness analysis we performed whole brain high resolution T1-weighted magnetic resonance imaging (MRI) on 15 ACLF and 10 healthy volunteers at 3T clinical MR scanner. Proton MR Spectroscopy ((1)H MRS) was also performed to measure level of altered metabolites. Out of 15 ACLF patients 10 survived and underwent follow-up study after clinical recovery at 3 weeks. FreeSurfer program was used to quantify cortical thickness and LC- Model software was used to quantify absolute metabolites concentrations. Neuropsychological (NP) test was performed to assess the cognitive performance in follow-up ACLF patients compared to controls. RESULTS: Significantly reduced cortical thicknesses in multiple brain sites, and significantly decreased N-acetyl aspartate (NAA), myo-inositol (mI) and significantly increased glutamate/glutamine (glx) metabolites were observed in ACLF compared to those of controls at baseline study. Follow-up patients showed significant recovery in cortical thickness and Glx level, while NAA and mI were partially recovered compared to baseline study. When compared to controls, follow-up patients still showed reduced cortical thickness and altered metabolites level. Follow-up patients had abnormal neuropsychological (NP) scores compared to controls. CONCLUSIONS: Neuronal loss as suggested by the reduced NAA, decreased cellular density due to increased cerebral hyperammonemia as supported by the increased glx level, and increased proinflammatory cytokines and free radicals may account for the reduced cortical thickness in ACLF patients. Presence of reduced cortical thickness, altered metabolites and abnormal NP test scores in post recovery subjects as compared to those of controls is associated with incomplete clinical recovery. The current imaging protocol can be easily implemented in clinical settings to evaluate and monitor brain tissue changes in patients with ACLF during the course of treatment.

Respiratory dysfunction is common in patients with achalasia and improves after pneumatic dilation.

BACKGROUND: Dysphagia, regurgitation, and chest pain are common achalasia, with a variable report of pulmonary symptoms possibly due to micro-aspiration. Pneumatic dilation (PD) may improve pulmonary function. Data on pulmonary dysfunction among achalasia patients are scanty, and the effect of PD is unknown. AIM: To evaluate pulmonary dysfunction in patients with achalasia based on clinical and radiologic evaluation and spirometry and to study the effect of PD at 1-month follow-up. METHODS: Patients with achalasia (diagnosed using high-resolution manometry and the Chicago classification) were evaluated prospectively by spirometry before (n = 38) and 1 month after PD (n = 31). All patients received a chest X-ray, and patients with respiratory abnormality before PD received high-resolution computed tomography of the thorax. RESULTS: Of the 38 patients, 17 and 21 had type I and II achalasia, respectively. The respiratory symptoms, such as pharyngeal symptoms [27/38 (71 %) vs. 8/31 (26 %); P = 0.0001], cough [23/38 (60.5 %) vs. 5/31 (16 %), P = 0.0001], and dyspnea [8/38 (21 %) vs. 0/31 (0 %), P = 0.006], improved after treatment with PD. Spirometry showed abnormalities in 17/38 (45 %) patients before and in 8/15 (53 %) after PD. Median FEV(1), FVC, PEFR, and percentage of predicted MEF(25-75), improved from 78 % (36-85), 74 % (48-100), 62 % (18-72), and 48 % (15-66) before to 83 % (58-94), 86 % (55-99), 69 % (38-81), and 59 % (33-78) after PD, respectively (P < 0.05 for all). CONCLUSION: Respiratory symptoms and spirometry abnormalities are common in patients with achalasia and improved after successful PD.

Risk Factors for Post-Endoscopic Retrograde Cholangio-Pancreatography Pancreatitis in Children With Chronic Pancreatitis and Its Prediction Using 4-Hour Postprocedure Serum Amylase and Lipase Levels.

BACKGROUND: Post-endoscopic retrograde cholangio-pancreatography pancreatitis (PEP) is seen in 3% to 16% of children undergoing therapeutic endoscopic retrograde cholangio-pancreatography (ERCP). We evaluated the risk factors of PEP and utility of 4-hour post-ERCP amylase and lipase for early prediction of PEP in children with chronic pancreatitis (CP). MATERIALS AND METHODS: Thirty children with CP (boys 20, 14.3 [interquartile range, 9.3-16] years) who underwent 62 ERCP procedures were studied. Clinical and procedural details with outcome were noted. Serum amylase and lipase were measured before, 4 hours, and 24 hours after ERCP. Multivariate analysis was done to identify risk factors for PEP. Cutoff scores of 4-hour amylase and lipase were identified. RESULTS: PEP occurred in 14.5% (9/62) of ERCP procedures (mild, 8; moderate, 1) with no mortality. On univariate analysis, endoscopic sphincterotomy ( P = 0.04), difficult cannulation ( P = 0.004), and prior PEP ( P = 0.036) were risk factors, while prior ERCP ( P = 0.04) was protective. Difficult cannulation (odds ratio, 5.83; 95% confidence interval, 1.329-25.592) was the independent risk factor on multivariate analysis overall and for first ERCP session alone. Amylase >3.3 times upper limit of normal (ULN) and lipase of >5 times ULN at 4 hours had best sensitivity and specificity for diagnosis of PEP. All cases with PEP were symptomatic by 6 hours and none had amylase/lipase <3 ULN at 4 hours. Amylase/lipase of <3 ULN at 4 hours could exclude PEP with good sensitivity (100%) and specificity (76% and 81%, respectively). CONCLUSIONS: PEP occurred in 14.5% of procedures in children with CP, with difficult cannulation being the independent risk factor. Asymptomatic patients with 4-hour amylase/lipase <3 times ULN can be safely discharged.

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.
