Weight Loss and Weight Regain in Usual Clinical Practice: Results From the TARGET-NASH Observational Cohort.

First-line treatment for nonalcoholic fatty liver disease (NAFLD) focuses on weight loss through lifestyle modifications.1,2 Weight loss ≥5% results in reduction of steatosis and weight loss ≥10% has been associated with improvement in hepatic inflammation and fibrosis.3 The incidence and sustainability of weight loss among patients with NAFLD were estimated and associating factors identified.

Predictors of No-show Rate in the GI Endoscopy Suite at a Safety Net Academic Medical Center.

BACKGROUND/OBJECTIVES: Noncompliance with physician and procedure appointments is associated with poor disease control and worse disease outcomes. This also impacts the quality of care, decreases efficiency, and affects revenue. Studies have shown that no-show rates are higher in clinics caring for underserved populations and may contribute to poorer health outcomes in this group. METHODS: We performed a 17-month retrospective observational cohort study of patients scheduled for outpatient procedures in the Gastroenterology endoscopy suite at the University of Florida Health, Jacksonville. Multivariate logistic regression analysis was performed to evaluate associations between attendance and predictors of no-show. RESULTS: In total, 6157 patients were scheduled to undergo different GI procedures during the study period. A total of 4388 (71%) patients completed their procedure, whereas 2349 (29%) failed to attend their appointment and were considered "no-show". There was a significant relationship between the visit attendance and race, insurance, gender, and marital status. Males had a higher no-show rate compared with females (30% vs. 28%; P<0.05). African Americans had the highest no-show rate (32%; P<0.05) amongst different races. Patients scheduled for surveillance colonoscopy (ie, history of polyps, IBD, Colon cancer) were more likely to show (78%) than those obtaining initial colorectal cancer screening (74%) or other indications (71%) (P<0.05).In the logistic regression model, patients with commercial insurance are more likely to show for their appointments than those with noncommercial insurance (eg, Medicare, Medicaid, City contract etc) [odds ratio (OR), 2.6; 95% confidence interval (CI), 2.2-3.0]. The odds of showing up are 1.7 times higher for married men compared with single men (OR, 1.7; 95% CI, 1.3-2.0). Similarly, married females are more likely to show up for appointment than single females (OR, 1.1; 95% CI, 0.9-1.3). We did not find significant association between the type of GI procedure (eg, colonoscopy vs. esophagogastroduodenoscopy vs. advanced endoscopic procedures) (P>0.05). CONCLUSIONS: Predictors of no-shows for endoscopic gastrointestinal procedures included unpartnered or single patients, African American race and noncommercial insurance providers. Patients scheduled for surveillance colonoscopy had better adherence than initial screening. Further studies are required to better characterize these factors and improve adherence to the outpatient appointments based on the identified predictors.

Barriers to treatment of chronic hepatitis C with direct acting antivirals in an urban clinic.

INTRODUCTION AND AIM: Direct-acting antiviral (DAA) agents are highly effective for treatment of chronic hepatitis C virus (HCV) yet access to treatment remains a serious challenge. The aim of this study was to identify barriers to treatment initiation with DAA-containing regimens in an urban clinic setting. MATERIALS AND METHODS: A retrospective cohort of all chronic HCV patients seen in an urban academic practice in Jacksonville, FL, USA from 1/2014 to 1/2017 was analyzed. Baseline characteristics were recorded and a review of medical records was performed to identify barriers to treatment initiation and overall success rates. RESULTS: Two-hundred and forty patients with chronic HCV were analyzed. Fifty-six percent of patients were African-American and 63% were insured through Medicaid/county programs or uninsured. Sixty-nine percent had barriers to initiating antiviral therapy categorized as psychosocial (n=112), provider (n=26), medical (n=20), and insurance-related factors (n=7). The most commonly encountered psychosocial barriers included failure to keep appointments (79/240, 33%), active substance abuse (18/240, 8%), and failure to obtain laboratory testing (11/240, 5%). Overall, only 27% of patients evaluated were initiated on DAA-containing regimens with 18% reaching SVR12 within the 36-month study period. CONCLUSION: In conclusion, only 27% of patients who presented to an urban academic practice with chronic HCV received DAA-containing regimens over a 36-month period. Psychosocial issues were the major barriers to antiviral therapy. These findings illustrate the need for an integrated approach that addresses psychosocial factors as well as comorbidities and adherence to care in order to increase rates of HCV treatment in at risk patients.

Prevalence and correlates of suspected nonalcoholic fatty liver disease in Chinese American children.

GOALS: The aim of this study was to evaluate the prevalence and clinical correlates of nonalcoholic fatty liver disease (NAFLD) in children of Chinese immigrants. BACKGROUND: NAFLD is increasing in prevalence and is frequently identified in children. High rates of NAFLD were found in adult Chinese immigrants. However, there are limited data regarding NAFLD in Chinese American children. STUDY: Clinical and laboratory data were collected from 407 children, aged 6 to 18 years, who had routine office visits at a Chinatown medical practice. Children were classified as having suspected NAFLD if common causes of liver disease were excluded, alanine aminotransferase levels exceeded established thresholds (>22.1 IU/L for girls and >25.8 IU/L for boys), and elevated alanine aminotransferase levels were confirmed by repeat measurement. RESULTS: 6.1% of Chinese American children had suspected NAFLD, including 33% of obese children. Seventeen percent of children were overweight, 14% were obese, and 52% had 25-hydroxy vitamin D levels <20 ng/mL. In univariable analysis, children with suspected NAFLD were more frequently male, had higher body mass index percentile and lipid levels, and lower vitamin D levels compared with children without evidence of NAFLD. In multivariable analysis, suspected NAFLD was associated with higher BMI percentile and lower vitamin D levels when adjusting for other factors. CONCLUSIONS: Chinese American children with obesity are at high risk for NAFLD. They should be screened accordingly, including testing for metabolic disorders and low vitamin D levels. Early identification of NAFLD in childhood will allow for intervention with lifestyle modification, providing a means to reduce the prevalence of NAFLD in children and adults.

Comparison of 24 vs 72-hour octreotide infusion in acute esophageal variceal hemorrhage - a multi-center, randomized clinical trial.

BACKGROUND: Current guidelines lack clarity about the optimal duration of octreotide therapy for patients with esophageal variceal hemorrhage (EVH). To address this lack of evidence, we conducted a randomized clinical trial (RCT) of 24-hours versus 72-hours continuous infusion of octreotide for patients with EVH. METHODS: This multi-center, prospective RCT (NCT03624517), randomized patients with EVH to 24-hour versus 72-hour infusion of octreotide. Patients were required to undergo esophageal variceal band ligation prior to enrollment. The primary endpoint was rebleeding rate at 72 hours. The study was terminated early due to an inability to recruit during and after the COVID-19 epidemic. RESULTS: For patients randomized to 72-hours (n = 19) of octreotide vs 24-hours (n = 15), there were no differences in the need for transfusion, average pRBC units transfused per patient (3 units vs 2 units), infection (5% vs 0%), mechanical ventilation (11% vs 7%), or the need for vasopressors (5% vs 3%), respectively (none of these differences were statistically significantly different). There were 2 re-bleeding events in the 72-hour group (11%), and no re-bleeding events in the 24-hour group (p = 0.49). 8/15 of patients receiving 24 hours of octreotide were discharged at or before hospital day 3 while none in the 72-hour group was discharged before day 3 (p < 0.001). There was one death (in the 72-hour group) within 30 days. CONCLUSIONS: A 24-hour infusion is non-inferior to a 72-hour infusion of octreotide for prevention of re-bleeding in patients with EVH. We propose that shortened octreotide duration may help reduce hospital stay and related costs in these patients.

Association Between Helicobacter pylori and Steatosis Severity on Transient Elastography.

Background A possible association between Helicobacter pylori (HP) infection and liver diseases including steatosis is suspected. There is a lack of studies evaluating the association of HP and liver steatosis severity using transient elastography. Aim The aim of this study was to evaluate the frequency and risk factors for liver steatosis measured by transient elastography in patients with or without HP. Methods A total of 484 patients tested for liver steatosis and fibrosis using transient elastography from January 2017 to June 2018 were evaluated. Ninety-one patients who were also tested for H. pylori infection were included in the study. Transient elastography findings were compared between HP-positive patients and HP-negative patients. Demographic, clinical, and laboratory variables and the presence and severity of liver fibrosis and steatosis were analyzed. Results Patients with HP had a higher frequency of steatosis on transient elastography (86.8% vs. 60.7%, p =0.009). Patients with HP had increased steatosis severity compared to HP-negative patients (mild steatosis 15.8% vs. 7.1%, p=0.037; moderate to severe steatosis 71.1% vs. 53.6%, p=0.015, respectively). In the stepwise multivariate logistic regression analysis, HP infection remained an independent risk factor for steatosis (odds ratio: 4.36, 95% confidence interval: 1.09-14.78; p=0.037). Conclusion Patients with HP had an increased steatosis frequency, and patients with liver steatosis may warrant HP evaluation and treatment.

Barriers to treatment of hepatitis B in an urban Chinatown community.

GOALS: To evaluate the net effect of a concerted effort to treat hepatitis B virus (HBV) in a Chinese immigrant population, including barriers to initiating and continuing therapy and antiviral efficacy. BACKGROUND: Oral antiviral agents for HBV achieve high rates of viral suppression. However, there is limited information about the impact of attempts to treat HBV in high prevalence immigrant communities. METHODS: Sixty-nine patients were identified in an urban Chinatown Internal Medicine practice who had indications for treatment of HBV. A coordinated effort was made to provide antiviral therapy to these patients. Barriers to starting treatment and reasons for discontinuation were categorized on the basis of a systematic review of medical records. Suppression of HBV DNA to undetectable levels was considered a treatment response. RESULTS: Twenty-six percent (18/69) of patients did not start medication because of failure to follow-up or treatment refusal. Oral antiviral therapy was initiated in 74% (51/69) of cases and 38 of 39 patients who remained on treatment achieved viral suppression. Twelve patients discontinued medication because of social, economic, or other reasons. In total, 55% (38/69) of treatment candidates achieved undetectable HBV DNA levels on therapy. CONCLUSIONS: Although oral antiviral therapy was highly effective in achieving viral suppression in patients who were maintained on treatment, only 55% of treatment candidates reached this endpoint. Barriers to care kept nearly one half of patients from initiating or continuing therapy. A multidisciplinary approach including education and social and financial support is needed to maximize the benefit of available HBV treatment in this urban immigrant population.

Esophageal Bronchial Artery Fistulaization: A Complication of an Endobronchial Ultrasound.

Bronchial artery pseudoaneurysms are an extremely rare cause of upper gastrointestinal bleeding. The presence of a bronchial artery pseudoaneurysm resulting in an esophageal fistula is an entity that, to our knowledge, has yet to be described. Successful management requires an interdisciplinary approach to guide closure of the defects. We present a novel case of an esophageal fistula and bronchial artery pseudoaneurysm resulting from an endobronchial ultrasound-guided transbronchial needle aspiration successfully managed by endoscopic therapy and coil embolization.

Endocrine Diseases and the Liver: An Update.

The endocrine system is a complex interconnected system of organs that control corporeal processes and function. Primary endocrine organs are involved in hormonal production and secretion but rely on a bevy of signals from the hypothalamic-pituitary axis and secondary endocrine organs, such as the liver. In turn, proper hepatic function is maintained through hormonal signaling. Thus, the endocrine system and liver are codependent, and diseases affecting either organs can lead to alterations in function within their counterparts. This article explores the hepato-endocrine relationship, including the effects on endocrine diseases on the liver.

Safety and efficacy of over-the-scope clip-assisted full thickness resection of duodenal subepithelial tumors: A case report.

BACKGROUND: Over-the-scope clip-assisted endoscopic full thickness resection (eFTR) of subepithelial tumors is a novel and promising endoscopic technique. Recently, there have been prospective studies investigating its use for colonic masses, but data regarding its use and efficacy in the duodenum are limited to a few reports. CASE SUMMARY: A 65-year-old African American female presents for evaluation of persistent gastroesophageal reflux disease not responsive to medical treatment. A 1 cm nodule was incidentally found in the duodenum and biopsies revealed a low grade well differentiated neuroendocrine tumor. The nodule was removed using over-the-scope clip-assisted eFTR and pathology revealed clear margins. We review the available literature with a discussion on the efficacy and safety of clip-assisted eFTR s of subepithelial lesions in the duodenum. CONCLUSION: Clip assisted eFTR appears to be a safe and efficacious treatment approach to duodenal subepithelial lesions. Further prospective studies are needed to investigate the long-term utility and safety of clip-assisted eFTR in the management of subepithelial duodenal lesions.

Comparison of EUS-guided versus percutaneous and transjugular approaches for the performance of liver biopsies.

BACKGROUND: Liver biopsy through endoscopic ultrasound (EUS) has become a novel approach for tissue acquisition. We aim to evaluate the adequacy of EUS-guided liver biopsies in comparison to those obtained through interventional radiology (IR) techniques. METHODS: A retrospective single-center analysis was performed of all IR (transjugular or image-guided percutaneous) and EUS-guided liver biopsies performed at an academic medical center from January 2016 to January 2018. Patient demographics, histologic characteristics, and clinical outcomes were collected. RESULTS: 152 procedures were included for analysis. 45% of liver biopsies were performed through EUS-guidance. The most common indication for liver biopsy was NASH fibrosis staging (n = 64). IR-guided biopsies contained a higher number of complete portal triads (13.6 vs. 10.8 p ≤ 0.01) while EUS-guided biopsies produced an increased total specimen length (4.6 cm vs. 3.6 cm p ≤ 0.01).47% of biopsy samples were fragmented with the majority of these (72%) occurring with EUS-guided procedures (p ≤ 0.01). IR-guided biopsies led to more complications in comparison to EUS-guided procedures (p = 0.03) CONCLUSION: Liver biopsies performed through EUS-guidance are comparable to IR-guided liver biopsies and may have an enhanced safety profile with acceptable tissue acquisition characteristics. Standardization of techniques and needles is needed for optimization of tissue sampling.

Helicobacter pylori is Associated with Less Fistulizing, Stricturing, and Active Colitis in Crohn's Disease Patients.

Introduction A potential protective role of Helicobacter pylori (HP) infection against the development of Crohn's disease (CD) has been postulated. There is a lack of studies evaluating the association of HP with CD phenotypes. The aim of this study was to investigate the clinical features and disease activity of patients with CD who were diagnosed with HP infection. Methods The charts of 306 consecutive patients from the inflammatory bowel disease (IBD) database at the University of Florida College of Medicine, Jacksonville from January 2014 to July 2016 were reviewed. Ninety-one CD patients who were tested for HP were included, and the frequencies of strictures, fistulas, and colitis in surveillance biopsies in these patients were evaluated. Results Of the 91 CD patients tested for HP, 19 had HP infection. A total of 44 patients had fistulizing/stricturing disease, and 62 patients had active colitis. In the univariate analysis, patients with HP infection had less fistulizing/stricturing disease (21.1% vs. 55.6%, p = 0.009) and less active colitis (42.1% vs. 77.1%, p = 0.005). In the multivariate analysis, HP infection remained as a protective factor for fistulizing/stricturing disease phenotype (OR: 0.22; 95%CI: 0.06-0.97; p = 0.022) and active colitis (OR: 0.186; 95%CI: 0.05-0.65; p = 0.010). Conclusion HP infection was independently associated with less fistulizing/stricturing disease and less active colitis in CD patients. Our study suggests CD patients with a history of HP infection are less prone to complications.

Ipilimumab and Nivolumab induced steroid-refractory colitis treated with infliximab: A case report.

BACKGROUND: A variety of immune-modulating drugs are becoming increasingly used for various cancers. Despite increasing indications and improved efficacy, they are often associated with a wide variety of immune mediated adverse events including colitis that may be refractory to conventional therapy. Although these drugs are being more commonly used by Hematologists and Oncologists, there are still many gastroenterologists who are not familiar with the incidence and natural history of gastrointestinal immune-mediated side effects, as well as the role of infliximab in the management of this condition. CASE SUMMARY: We report a case of a 63-year-old male with a history of metastatic renal cell carcinoma who presented to our hospital with severe diarrhea. The patient had received his third combination infusion of the anti-CTLA-4 monoclonal antibody Ipilimumab and the immune checkpoint inhibitor Nivolumab and developed severe watery non-bloody diarrhea the same day. He presented to the hospital where he was found to be severely dehydrated and in acute renal failure. An extensive workup was negative for infectious etiologies and he was initiated on high dose intravenous steroids. However, he continued to worsen. A colonoscopy was performed and revealed no endoscopic evidence of inflammation. Random biopsies for histology were obtained which showed mild colitis, and were negative for Cytomegalovirus and Herpes Simplex Virus. He was diagnosed with severe steroid-refractory colitis induced by Ipilimumab and Nivolumab and was initiated on Infliximab. He responded promptly to it and his diarrhea resolved the next day with progressive resolution of his renal impairment. On follow up his gastrointestinal side symptoms did not recur. CONCLUSION: Given the increasing use of immune therapy in a variety of cancers, it is important for gastroenterologists to be familiar with their gastrointestinal side effects and comfortable with their management, including prescribing infliximab.

Case Series of 10 Patients with Cirrhosis Undergoing Emergent Repair of Ruptured Umbilical Hernias: Natural History and Predictors of Outcomes.

OBJECTIVES: Ascites represents an important event in the natural history of cirrhosis, portending increased 1-year mortality. Umbilical herniation with rupture is an uncommon complication of large-volume ascites that is associated with significant morbidity and mortality. The aim of this study was to describe predictors of outcomes in patients undergoing emergent repair for spontaneous umbilical hernia rupture. MATERIALS AND METHODS: We report a case series of 10 patients with decompensated cirrhosis (mean age 66 ± 9 years, mean Model for End-Stage Liver Disease score of 21 ± 7) who presented with a ruptured umbilical hernia and had emergent repair. RESULTS: Thirty percent (3/10) of patients died or required liver transplant. Factors associated with death or transplant included the development of bacterial peritonitis (P = .03) and the presurgical 30-day Mayo Clinic Postoperative Mortality Risk in Patient with Cirrhosis Score (P = .03). CONCLUSIONS: Emergent repair after umbilical hernia rupture in patients with decompensated cirrhosis carries a poor prognosis with 30% of patients developing poor postsurgical outcomes.

Nutritional Considerations in Liver Disease.

Malnutrition occurs in most patients with advanced liver diseases and is associated with higher rates of morbidity and mortality. In this article, the authors discuss the pathophysiology of malnutrition and methods to optimize nutrition status in liver disease and include a brief section on perioperative and postoperative nutrition.

Botulinum Toxin as a Treatment for Refractory Gastroparesis: a Literature Review.

PURPOSE OF REVIEW: Gastroparesis (GP) is a disorder of gastrointestinal motility which leads to delayed gastric emptying in the absence of mechanical obstruction. Treatment is limited as many patients are refractory to dietary modification and the use prokinetic medications carry significant adverse risks. These limitations necessitate more research into experimental therapies. The purpose of this article is to summarize the known information and guidelines on the diagnosis and management of GP and to review the latest literature on experimental treatments. RECENT FINDINGS: Based on the current available literature, there is conflicting data regarding the efficacy of intra-pyloric botulinum injections (IPBIs) for refractory gastroparesis. There have been many open-label trials showing good clinical response, but the only two randomized controlled trials on the matter showed no objective improvement gastric emptying studies. However, both studies were likely underpowered and changes in gastric emptying may not correlate with symptom improvement. As such, these discouraging findings should not be used to exclude botox from the armamentarium of therapies for refractory GP. More large-scale, double-blinded, multicenter randomized control trials are needed to further validate the long-term efficacy and safety of IPBI, as well as gastric peroral endoscopic myotomy (G-POEM), as compared to gastric electrical stimulation (GES) or surgical intervention (i.e., laparoscopic pylorotomy) for refractory gastroparesis.

Intestinal Spirochetosis: An Obscure Cause of Lower Gastrointestinal Bleeding.

Adherence of spirochetes to the apical membrane of the colonic epithelium has been well-described in the literature, but the exact pathogenesis leading to symptomatic clinical manifestations is poorly understood. Most cases are found incidentally on the pathological evaluation of colonic biopsies taken during diagnostic or therapeutic colonoscopies. However, whether the colonization of the intestinal mucosa can be attributed to clinical symptoms is a matter of debate. Here, we present a case of intermittent hematochezia attributed to the overwhelming invasion of the colonic mucosa by intestinal spirochetes.

Intestinal Schistosomiasis: A Rare Cause of Abdominal Pain and Weight loss.

Abdominal pain is one of the most common reasons for outpatient visits. Although intestinal schistosomiasis is extremely rare in US, it should be considered in the differential diagnosis for those patients with risk factors such as international traveling history. This case report illustrates a unique case of intestinal schistosomiasis, which presented with an eight-week history of nonspecific abdominal pain and weight loss. Her colonoscopy revealed a 10 mm polyp in the colon. Endoscopic mucosal resection confirmed the diagnosis of schistosomiasis. Treatment with Praziquantel resulted in significant improvement of her symptoms.
