RESUMEN
BACKGROUND AND AIMS: Alcohol-associated hepatitis (AH) poses significant short-term mortality. Existing prognostic models lack precision for 90-day mortality. Utilizing artificial intelligence in a global cohort, we sought to derive and validate an enhanced prognostic model. APPROACH AND RESULTS: The Global AlcHep initiative, a retrospective study across 23 centers in 12 countries, enrolled patients with AH per National Institute for Alcohol Abuse and Alcoholism criteria. Centers were partitioned into derivation (11 centers, 860 patients) and validation cohorts (12 centers, 859 patients). Focusing on 30 and 90-day postadmission mortality, 3 artificial intelligence algorithms (Random Forest, Gradient Boosting Machines, and eXtreme Gradient Boosting) informed an ensemble model, subsequently refined through Bayesian updating, integrating the derivation cohort's average 90-day mortality with each center's approximate mortality rate to produce posttest probabilities. The ALCoholic Hepatitis Artificial INtelligence Ensemble score integrated age, gender, cirrhosis, and 9 laboratory values, with center-specific mortality rates. Mortality was 18.7% (30 d) and 27.9% (90 d) in the derivation cohort versus 21.7% and 32.5% in the validation cohort. Validation cohort 30 and 90-day AUCs were 0.811 (0.779-0.844) and 0.799 (0.769-0.830), significantly surpassing legacy models like Maddrey's Discriminant Function, Model for End-Stage Liver Disease variations, age-serum bilirubin-international normalized ratio-serum Creatinine score, Glasgow, and modified Glasgow Scores ( p < 0.001). ALCoholic Hepatitis Artificial INtelligence Ensemble score also showcased superior calibration against MELD and its variants. Steroid use improved 30-day survival for those with an ALCoholic Hepatitis Artificial INtelligence Ensemble score > 0.20 in both derivation and validation cohorts. CONCLUSIONS: Harnessing artificial intelligence within a global consortium, we pioneered a scoring system excelling over traditional models for 30 and 90-day AH mortality predictions.

RESUMEN
BACKGROUND & AIMS: Corticosteroids are the only effective therapy for severe alcohol-associated hepatitis (AH), defined by a model for end-stage liver disease (MELD) score >20. However, there are patients who may be too sick to benefit from therapy. Herein, we aimed to identify the range of MELD scores within which steroids are effective for AH. METHODS: We performed a retrospective, international multicenter cohort study across 4 continents, including 3,380 adults with a clinical and/or histological diagnosis of AH. The main outcome was mortality at 30 days. We used a discrete-time survival analysis model, and MELD cut-offs were established using the transform-the-endpoints method. RESULTS: In our cohort, median age was 49 (40-56) years, 76.5% were male, and 79% had underlying cirrhosis. Median MELD at admission was 24 (19-29). Survival was 88% (87-89) at 30 days, 77% (76-78) at 90 days, and 72% (72-74) at 180 days. A total of 1,225 patients received corticosteroids. In an adjusted-survival-model, corticosteroid use decreased 30-day mortality by 41% (hazard ratio [HR] 0.59; 0.47-0.74; p <0.001). Steroids only improved survival in patients with MELD scores between 21 (HR 0.61; 0.39-0.95; p = 0.027) and 51 (HR 0.72; 0.52-0.99; p = 0.041). The maximum effect of corticosteroid treatment (21-30% survival benefit) was observed with MELD scores between 25 (HR 0.58; 0.42-0.77; p <0.001) and 39 (HR 0.57; 0.41-0.79; p <0.001). No corticosteroid benefit was seen in patients with MELD >51. The type of corticosteroids used (prednisone, prednisolone, or methylprednisolone) was not associated with survival benefit (p = 0.247). CONCLUSION: Corticosteroids improve 30-day survival only among patients with severe AH, especially with MELD scores between 25 and 39. LAY SUMMARY: Alcohol-associated hepatitis is a condition where the liver is severely inflamed as a result of excess alcohol use. It is associated with high mortality and it is not clear whether the most commonly used treatments (corticosteroids) are effective, particularly in patients with very severe liver disease. In this worldwide study, the use of corticosteroids was associated with increased 30-day, but not 90- or 180-day, survival. The maximal benefit was observed in patients with an MELD score (a marker of severity of liver disease; higher scores signify worse disease) between 25-39. However, this benefit was lost in patients with the most severe liver disease (MELD score higher than 51).

BACKGROUND : Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common and most serious complication of ERCP. Our aim was to estimate the nationwide incidence, temporal trends, and mortality of PEP in the United States and to establish risk factors associated with PEP development. METHODS : This was a retrospective cohort study analyzing Nationwide Inpatient Sample data from 2011 to 2017 using International Classification of Diseases codes. The primary outcomes were trends in PEP incidence and predictors of PEP development. Secondary outcomes were in-hospital mortality, length of hospital stay, and admission to the intensive care unit. RESULTS : Of 1â222â467 adult patients who underwent inpatient ERCP during the study period, 55â225 (4.5â%) developed PEP. The hospital admission rate of PEP increased by 15.3â%, from 7735 in 2011 to 8920 in 2017 (odds ratio [OR] 1.23, 95â% confidence interval [CI] 1.04â-â1.46; Pâ=â0.02). The overall rate of mortality increased from 2.8â% of PEP cases in 2011 to 4.4â% in 2017 (OR 1.62, 95â%CI 1.10â-â2.38; Pâ=â0.01). Multiple patient-related (alcohol use, cocaine use, obesity, chronic kidney disease, heart failure), procedure-related (therapeutic ERCP, sphincterotomy, pancreatic duct stent placement, sphincter of Oddi dysfunction), and hospital-related (teaching hospitals, hospitals located in the West and Midwest) factors that impact the occurrence of PEP were identified. CONCLUSIONS : Our study showed rising hospital admission and mortality rates associated with PEP in the United States. This calls for a greater recognition of this life-threatening complication and amelioration of its risk factors, whenever possible.

BACKGROUND: Emerging evidence suggests an association between acute pancreatitis and COVID-19. Our objective is to conduct a systematic review and meta-analysis to evaluate whether COVID-19 affects the severity and outcomes associated with acute pancreatitis. METHODS: Cochrane guidelines and PRISMA statement were followed for this review. Digital dissertation bases were searched and all studies comparing the outcomes of acute pancreatitis amongst patients with and without COVID-19 were included. We compared the etiology, severity, length of hospital stay and mortality associated with acute pancreatitis in patients with and without COVID-19. RESULTS: Four observational studies with a total of 2,419 patients were included in the review. Presence of COVID-19 significantly increased the odds of mortality (OR 4.10, 95% CI 2.03-8.29) in patients with acute pancreatitis. These patients also had an increased incidence of severe pancreatitis (OR 3.51, 95% CI 1.19-10.32), necrotizing pancreatitis (OR 1.84, 95% CI 1.19-2.85) and a longer length of hospital stay (OR 2.88, 95% CI 1.50-5.52), compared to non-COVID patients. Patients with COVID-19 were more likely to have an unknown or idiopathic etiology of acute pancreatitis (OR 4.02, 95% CI 1.32-12.29), compared to non-COVID-19 patients. CONCLUSION: Current evidence suggests that COVID-19 adversely impacts the morbidity and mortality associated with acute pancreatitis. SARS-CoV-2 may be a causative agent for acute pancreatitis. Further population-based studies are needed to confirm or refute these findings.

BACKGROUND AND AIM: A delay in performing colonoscopies after positive fecal tests in a screening program may risk neoplastic progression. Our objective is to conduct a systematic review and meta-analysis to evaluate the effects of timing of a colonoscopy after a positive fecal test on the detection of colorectal cancer. METHODS: Cochrane guidelines and PRISMA statement were followed for this review. Digital dissertation databases were searched from inception to June 1, 2020, and all studies reporting the detection rates of colorectal cancer on the basis of different time intervals between a positive fecal test and the post-test colonoscopy were included. We compared the detection rates of colorectal cancer (overall and advanced-stage) and advanced adenoma based on different time intervals. RESULTS: A total of 361 637 patients from six observational studies were included for the analysis. The odds of detecting any colorectal cancer (odds ratio [OR] 1.58, 95% confidence interval [CI] 1.23-2.03, P < 0.001), advanced-stage colorectal cancer (OR 2.16, 95% CI 1.47-3.16, P < 0.001), or advanced adenomas (OR 1.17, 95% CI 1.06-1.28, P = 0.001) are significantly higher if the colonoscopies are performed after 6 months from a positive fecal test, compared with within 6 months. There was no significant difference in the detection rates based on a 1-month, a 2-month, or a 3-month cut-off. CONCLUSIONS: A delay of colonoscopies beyond 6 months after positive fecal tests is associated with a higher odds of detecting colorectal cancer. A timely follow up of patients with positive fecal tests is warranted.

BACKGROUND AND AIMS: The nature and outcomes of infection among patients with cirrhosis in safety-net hospitals are not well described. We aimed to characterize the rate of and risk factors for infection, both present on admission and nosocomial, in this unique population. We hypothesized that infections would be associated with adverse outcomes such as short-term mortality. METHODS: We used descriptive statistics to characterize infections within a retrospective cohort characterized previously. We used multivariable logistic regression models to assess potential risk factors for infection and associations with key outcomes such as short-term mortality and length of stay. RESULTS: The study cohort of 1112 patients included 33% women with a mean age of 56 ± 10 years. Infections were common (20%), with respiratory and urinary tract infections the most frequent. We did not observe a difference in the incidence of infection on admission based on patient demographic factors such as race/ethnicity or estimated household income. Infections on admission were associated with greater short-term mortality (12% vs 4% in-hospital and 14% vs 7% 30-day), longer length of stay (6 vs 3 days), intensive care unit admission (28% vs 18%), and acute-on-chronic liver failure (10% vs 2%) (p < 0.01 for all). Nosocomial infections were relatively uncommon (4%), but more frequent among patients admitted to the intensive care unit. Antibiotic resistance was common (38%), but not associated with negative outcomes. CONCLUSION: We did not identify demographic risk factors for infection, but did confirm its morbid effect among patients with cirrhosis in safety-net hospitals.

BACKGROUND AND AIMS: Several criteria have been described to noninvasively predict the presence of high-risk esophageal varices in patients with compensated advanced chronic liver disease (cACLD). However, a recent study showed that treatment with ß blockers could increase decompensation-free survival in patients with clinically significant portal hypertension, thereby making it important to predict the presence of any esophageal varices. We aimed to develop a simple scoring system to predict any esophageal varices. METHODS: We retrospectively reviewed patients who had vibration-controlled transient elastography (VCTE) at Cook County Hospital, Chicago, USA. Patients with cACLD and liver stiffness measurement (LSM) ≥ 10 kPa with esophagogastroduodenoscopy performed within one year of VCTE were analyzed. We generated a novel score to predict esophageal varices, using the beta coefficient of predictive variables. The score was validated in an external cohort at the University of Iowa Hospital, USA. RESULTS: There were 372 patients in the development cohort and 200 patients in the validation cohort. LSM, platelet count, and albumin were identified as predictors of esophageal varices and were included for generating the Cook County score as "platelet count * - 0.0155872 + VCTE score * 0.0387052 + albumin * - 0.8549209." The area under receiver operating curve for our score was 0.86 for any varices and 0.85 for high risk varices and avoided more endoscopies than the expanded Baveno VI criteria while maintaining a very low miss rate (negative predictive value > 99%). CONCLUSION: We propose a new, highly accurate, and easy-to-use scoring system to predict the presence of not only high-risk but any esophageal varices in patients with cACLD.

BACKGROUND: The causes and management of pyogenic liver abscess (PLA) have undergone multiple changes over the past decades. It is a relatively rare disease in the USA, and its incidence rate in the USA is increasing. The last US community hospital experience of PLA was published in 2005. We performed a retrospective study of patients admitted with PLA to an urban safety net hospital. AIMS: To ascertain risk factors, management approaches, and outcomes of PLA. METHODS: Electronic medical record was queried for diagnosis codes related to PLA during the years 2009-2018. Clinical information was compiled in an electronic database which was later analyzed. Main study outcomes were in-hospital mortality, 30-day readmission rate, and intensive care utilization rate. RESULTS: A total of 77 patients with PLA were admitted in the study period. Most common risk factors were diabetes mellitus (23.4%), previous liver surgery (20.7%), and hepatic malignancy (16.9%). 89% of patients were treated with percutaneous drainage or aspiration, and surgical drainage was reserved for other with other indications for laparotomy. In-hospital mortality, 30-day readmission, and intensive care utilization rates were 2.6%, 7% and 22%, respectively. Median length of stay was 11 days (inter-quartile range 7). Rate of antimicrobial resistance in abscess fluid cultures was 40%; 13 cases of Klebsiella pneumoniae liver abscess were noted in our cohort, most of whom were Hispanic or Asian. CONCLUSIONS: PLA was principally managed by percutaneous drainage or aspiration with good outcomes. Further studies investigating the racial predilection of K. pneumoniae liver abscesses could reveal clues to its pathogenesis.

BACKGROUND: Modified Marshall Score is one of the severity scores for acute pancreatitis (AP) and is included in the Revised Atlanta Classification, but given its utilization of a set serum creatinine level (sCr), it may misclassify stable patients with chronic kidney disease (CKD) to a more severe class just due to their elevated sCr. AIMS: Our study aims to evaluate the role of CKD in AP and the possibility of utilizing acute kidney injury (AKI) into developing a new scoring system. METHODS: We retrospectively reviewed the electronic medical records of three hundred consecutive patients who were diagnosed with AP during hospitalization. Multiple demographic variables and clinical course indices were collected. Univariate logistic regression was then applied to predict mortality and ICU admission. Finally, receiver operating curve was utilized to compare original versus New Revised Marshall Score. RESULTS: Two hundred and eight-four (284) patients had a definitive diagnosis of AP. When comparing patients who had AKI on admission to those without AKI, the AKI group showed statistically significant higher mortality rate (5.6% vs. 1.1%, p = 0.04). Finally, we substituted the renal part of Marshall Score with our AKIN and we plotted the New "Revised" Marshall Score, which showed a higher AUROC compared to the original modified version (C-statistics 0.93 vs. 0.89, p < 0.05). CONCLUSION: We found that AKI predicts mortality and outperforms the use of a fixed sCr value alone. The use of our New Revised Marshall Score can accurately classify AP severity, avoiding misclassification of AP severity and providing better patient care.

BACKGROUND: Crohn's disease is an idiopathic inflammatory process that is occasionally associated with complications, which cause significant morbidity and mortality. The anti-inflammatory effect of cannabis in intestinal inflammation has been shown in several experimental models; it is unknown whether this correlates with fewer complications in Crohn's disease patients. AIMS: To compare the prevalence of Crohn's disease-related complications among cannabis users and non-users in patients admitted with a primary diagnosis of Crohn's disease or a primary diagnosis of Crohn's related complication and a secondary diagnosis of Crohn's disease between 2012 and 2014. METHODS: We used data from the Healthcare Cost and Utilization Project-National Inpatient Sample. Cannabis users (615) were compared directly after propensity score match to non-users, in aspects of various complications and clinical end-points. RESULTS: Among matched cohorts, Cannabis users were less likely to have the following: active fistulizing disease and intra-abdominal abscess (11.5% vs. 15.9%; aOR 0.68 [0.49 to 0.94], p = 0.025), blood product transfusion (5.0% vs. 8.0%; aOR 0.48 [0.30 to 0.79], p = 0.037), colectomy (3.7% vs. 7.5%; aOR 0.48 [0.29-0.80], p = 0.004), and parenteral nutrition requirement (3.4% vs. 6.7%, aOR 0.39 [0.23 to 0.68], p = 0.009). CONCLUSION: Cannabis use may mitigate several of the well-described complications of Crohn's disease among hospital inpatients. These effects could possibly be through the effect of cannabis in the endocannabinoid system.

WHAT IS KNOWN AND OBJECTIVE: Drug-induced liver injuries (DILI) are overall rare and often associated with use of medications. Medications are also the most common aetiology of Stevens-Johnson syndrome (SJS), but SJS is seldom seen concomitantly with liver injury. Many common drugs can cause either one of these conditions; however, there are no reported cases of concomitant DILI and SJS secondary to fluoxetine. CASE SUMMARY: A 41-year-old female presented with a skin rash and abnormal liver function tests after the recent initiation of fluoxetine. Skin and liver biopsies showed features of SJS and DILI, respectively. Fluoxetine was stopped, following which there was improvement in her liver function tests and skin rash, without progression to fulminant hepatic failure. WHAT IS NEW AND CONCLUSION: Commonly used and safe pharmaceuticals such as fluoxetine have the potential for serious adverse events affecting the skin and liver.

INTRODUCTION: Recent studies attribute promising prognostic values to various inflammatory biomarkers in acute pancreatitis, including the following: the neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and red cell distribution width (RDW). We aimed to determine the performance of these biomarkers for detecting disease severity in patients with hypertriglyceridemia-induced acute pancreatitis (HTG-AP). METHODS: We retrospectively reviewed 110 patients with HTG-AP and compared the NLR, PLR, and RDW in different severity groups. We performed receiver-operating characteristic (ROC) analysis to identify the optimal cut-off value for NLR to predict severe AP. RESULTS: NLR was significantly higher in patients with severe AP than mild and moderately severe AP (14.6 vs. 6.9, p < 0.001), and higher with organ failure upon presentation (9.1 vs. 7.1, p = 0.026). After dichotomization by the optimal cut-off value of 10 as determined by the ROC curve, the high-NLR group had a significantly longer length of stay (9.1 vs. 6.6 days, p = 0.001), duration of nil per os (4.9 vs. 3.7 days, p = 0.007), and higher rates of complications, including systemic inflammatory response syndrome (81.5% vs. 44.6%, p = 0.001) and persistent acute kidney injury (25.9% vs. 3.6%, p < 0.001). High NLR independently predicted severe acute pancreatitis in multivariate analysis (Odds ratio 6.71, p = 0.019). CONCLUSION: NLR represents an inexpensive, readily available test with a promising value to predict disease severity in HTG-AP. Among the three inflammatory biomarkers, NLR has the highest discriminatory capacity for severe HTG-AP, with an optimal cut-off value of 10.

Abstracts Objectives: Cardiogenic ascites has been well described regarding its pathophysiology and fluid characteristics in prior literatures. However, ascites in patients with cardiac cirrhosis has not been characterized as a separate entity despite its unique pathophysiology and clinical aspects. This study aims to describe the fluid profile of ascites of cardiac cirrhosis and explore the utility of ascitic fluid protein (AFP) to predict concurrent cardiac cirrhosis. METHODS AND MATERIALS: We retrospectively selected and reviewed samples from the patients with cardiogenic ascites with and without concurrent cardiac cirrhosis. Epidemiologic characters, serum laboratory values, and fluid characteristics were directly compared between the groups. RESULTS: We analyzed 20 samples of ascitic fluid from the patients of cardiac cirrhosis and compared with 48 samples of non-cirrhotic cardiac ascites. The AFP was significantly lower in patients with cardiac cirrhosis (3.66g/dl) as compared to non-cirrhotic patients (4.31g/dl, p < .01); while there was no difference in serum-ascites albumin gradient (1.48g/dl vs. 1.47g/dl, p = .95). AFP equal to or less than 4.3g/dl predicted cirrhosis with a sensitivity of 95% and negative likelihood ratio of 0.10; the corresponding ROC curve of AFP has an AUC of 0.777, higher than AUC of other noninvasive prediction models. CONCLUSIONS: We presented the first fluid characterization of ascites in patients with cardiac cirrhosis. AFP was significantly lower than that from non-cirrhotic cardiac ascites, likely secondary to decreased serum protein level. AFP equal to or less than 4.3g/dl could be utilized to screen for concurrent cardiac cirrhosis with high sensitivity in patients with cardiogenic ascites without other predisposing factors for liver injury.

BACKGROUND AND AIMS: Eosinophilic esophagitis (EoE) is a clinicopathologic condition characterized by symptoms of esophageal dysfunction in the presence of eosinophil-predominant inflammation of esophageal mucosa. Topical steroids are recommended as first line pharmacologic therapy in EoE. We aimed to determine the efficacy of topical steroids in inducing histologic and clinical remission in children and adults with EoE. METHODS: We performed a systematic search of the MEDLINE, EMBASE, Scopus, and Cochrane library databases for studies investigating the efficacy of topical steroids in EoE. We collected data on the number of patients, dose and duration of therapy, complete and partial histological response, and clinical improvement. We performed meta-analysis of placebo-controlled randomized clinical trials using Review Manager version 5.2. We used funnel plots to evaluate for publication bias. RESULTS: Five studies that included 174 patients with EoE were included in the meta-analysis. Topical fluticasone was administered in three studies involving 114 patients, and topical budesonide in two studies involving 60 patients. Patients treated with topical steroids, as compared with placebo, had higher complete histological remission (odds ratio [OR] 20.81, 95% confidence interval [CI] 7.03, 61.63) and partial histological remission (OR 32.20, 95% CI 6.82, 152.04). There was a trend towards improvement in clinical symptoms with topical steroids as compared with placebo but it did not reach statistical significance (OR 2.72, 95 %CI 0.90, 8.23). CONCLUSIONS: Topical corticosteroids seem to be effective in inducing histological remission but may not have similar significant impact in improving clinical symptoms of EoE. Studies with large sample size are needed to uniformly validate symptom improvement in EoE.

BACKGROUND: Thrombocytopenia has been shown to be the single most useful laboratory investigation for identifying subclinical cirrhosis of varying etiologies. However, alcohol per se can result in thrombocytopenia, and hence it is unclear whether platelet count can identify cirrhosis in patients who are alcoholic. OBJECTIVES: To characterize the utility of clinical predictors, especially platelet count, for identifying the presence of cirrhosis in alcoholics. To develop a simple, objective model for identifying cirrhosis in alcoholics. DESIGN: Retrospective cohort study. PARTICIPANTS: A total of 2,471 consecutive hospitalized patients with abnormal liver enzyme levels were screened, from which 272 patients with a history of recent and ongoing alcohol intake, negative diagnostic studies for alternative etiologies of chronic liver disease, and recent liver imaging with ultrasound or CT scan were included. MAIN MEASURES: Results of liver imaging and admission laboratory studies including liver enzymes, coagulation studies, and blood counts. KEY RESULTS: One hundred twenty-nine patients (47%) had cirrhosis based on imaging; 143 patients (53%) had no cirrhosis. A pre-sobriety platelet count (during ongoing alcohol intake) of less than 70*10(3) cells/mm(3) was effective for ruling in cirrhosis (positive likelihood ratio [LR] 6.8, 95% CI: 3.4, 14); platelet count greater than 200*10(3) was useful for ruling out cirrhosis in alcoholics (negative LR 0.18, 95% CI: 0.10, 0.35). Multivariate logistic regression analysis identified international normalized ratio (INR) (p < 0.01) and pre-sobriety platelet count (p < 0.01) as independent predictors of cirrhosis. A Model for identifying Cirrhosis in Alcoholic Liver Disease (MCALD) was developed using the INR and pre-sobriety platelet count; it had an area under the receiver operating characteristic curve of 0.89 and Hosmer-Lemeshow goodness of fit chi(2) (p value) of 8.9 (0.35) for predicting cirrhosis in alcoholics. A MCALD score > 5.5 corresponded to an increased likelihood of cirrhosis (LR: 6.5, 95% CI: 4.3, 11.0) and a MCALD score < 5.5 corresponded to decreased likelihood of cirrhosis in alcoholics (LR: 0.25, 95% CI: 0.19, 0.36). Sobriety platelet count (after alcohol abstinence) at a cutoff of 160*10(3) had positive LR of 7.9 (95% CI: 4.4, 14) and negative LR of 0.42 (95% CI: 0.34, 0.52) for predicting cirrhosis in alcoholics. CONCLUSIONS: A simple model of platelet count and INR has good diagnostic accuracy for identifying cirrhosis in alcoholics.

GOALS: To compare the efficacy and tolerability of morning-only polyethylene glycol (PEG) with split-dose preparation in hospitalized patients scheduled for colonoscopy. BACKGROUND: Morning-only colonoscopy preparation may improve efficiency by allowing patient preparation and colonoscopy to be performed on the same day. There are limited data comparing morning-only with split-dose preparation, and more studies are needed before morning-only preparation can be routinely recommended. STUDY: A single-center, prospective, endoscopist-blinded study was conducted, in which hospitalized patients scheduled to undergo diagnostic colonoscopy were randomly assigned to receive 4 L of PEG either on the morning of colonoscopy or as a split-dose (evening-morning). The primary endpoint was efficacy of bowel preparation measured by the Ottawa scale. Secondary endpoints were patient compliance and tolerance. RESULTS: A total of 120 hospitalized patients scheduled for diagnostic colonoscopy were randomized. The mean total Ottawa score was slightly superior for the morning-only arm, and the upper bound of 95% confidence interval (CI) for difference between arms was less than our prespecified noninferiority margin of 1.5 (difference=-0.23; 95% CI, -1.72 to 1.25). The percentage of patients with good bowel preparation was similar for all colonic segments. There was a trend toward more side effects among patients in the morning-only compared with the split-dose arm (71% vs. 54%; P=0.08). Compared with morning-only preparation, more patients in the split-dose arm were willing to undergo similar preparation for future colonoscopies (71% vs. 89%; P=0.02). CONCLUSIONS: Morning-only PEG is not inferior to split-dose preparation regarding bowel cleansing efficacy for colonoscopy in hospitalized patients. However, split-dose preparation was preferred by patients because of less side effects.

BACKGROUND: Plasma and hepatic lipid abnormalities are frequent in hepatitis C infected individuals. METHODS: Plasma lipid and medical records profiles were prospectively obtained in 130 consecutive individuals seen by a single hepatologist in a university liver disease clinic. The relationships between viral load, genotype, plasma lipid fractions, HDL, LDL particle number and particle size were examined. RESULTS: Of 130 individuals studied, 74 had hepatitis C while 15 had NAFLD/NASH and 30 had alcohol related liver disease. The LDL particle number and LDL-C levels did not differ between those with and without hepatitis C although the number of small LDL particles was greater in those with hepatitis C infection. The HDL-C and total cholesterol levels were greater in those without hepatitis C than those with hepatitis C (P = 0.009). In contrast, the serum triglyceride level was greater in the hepatitis C viral group (P = 0.013). Importantly, the hepatitis C viral load regardless of the genotype correlated directly with the triglyceride and VLDL levels with r values of 0.73 and 0.84, respectively. CONCLUSIONS: There are: (1) important differences in lipid classes, number and the size of lipid particles exist between hepatitis C virus infected and noninfected liver disease groups, (2) the serum total triglyceride and the LDL levels correlate significantly with the hepatitis C viral load and, (3) Serum triglyceride level may play an important role in viral replication. These data further suggest that therapies directed at lowering plasma triglyceride levels may enhance the efficacy of current antiviral treatment regimens.
