GOAL: The purpose of this study was to assess the effect of decreased colonoscopy reimbursement on gastroenterologist practice behavior, including time to retirement and procedure volume. BACKGROUND: In 2015, the Centers for Medicare and Medicaid Services proposed reductions in colonoscopy reimbursements. With new initiatives for increased colorectal cancer screening, it is crucial to understand how reimbursement changes could affect these efforts. STUDY: Randomly selected respondents from the American College of Gastroenterology membership database were surveyed on incremental changes in practice behavior if colonoscopy reimbursement were to decrease by 10, 20, 30, or 40 %. Data were analyzed using both Pearson's Chi-square and analysis of variance. RESULTS: Two thousand and nine gastroenterologists received the survey with a 16.3 % response rate. Procedure volume significantly decreased with degree of reimbursement reductions (p < 0.001). With a 10 % decrease, 72 % of respondents reported no change in the number of colonoscopies performed. With a 20 % decrease, 39 % would decrease their procedure volume, while 21 % of respondents would increase their procedure volume. With a 30 and 40 % decrease, procedure volume decreased by 48 and 50 %, respectively. In terms of retirement, current plans predict a cumulative retirement rate of 29.4 % at 10 years. More than 42 % of respondents plan to retire after 2030. In the 2014-2023 retirement subgroup (N = 74 responses), there was a significant hastening of retirement year at 20 % (p = 0.016), 30 % (p < 0.001), and 40 % (p < 0.001) reimbursement reductions as compared to baseline responses. CONCLUSION: Decreasing colonoscopy reimbursements may have a significant effect on the effective gastroenterology work force.

Depression, common in chronic medical conditions, and hepatic encephalopathy (HE), a reversible neuropsychiatric syndrome due to liver dysfunction, are associated with impaired health-related quality of life (HRQOL) in cirrhosis and hepatitis C (HCV). This study investigated the impact of depression and HE on HRQOL in cirrhotic patients with HCV. A convenience sample of 43 ambulatory patients, with varying degrees of cirrhosis secondary to HCV, was prospectively enrolled in this study. Participants were assessed for any current depressive, fatigue, and daytime sleepiness symptoms and underwent a psychometric evaluation to determine the presence of HE symptoms. Participants reported current HRQOL on general health and liver disease-specific questionnaires. Diagnosis and current health status were confirmed via medical records. The associations between disease severity, depressive symptoms, HE, fatigue, and daytime sleepiness were measured. Predictors of HRQOL in this sample were determined. Depressive symptoms (70 %) and HE (77 %) were highly prevalent in this sample, with 58 % actively experiencing both conditions at the time of study participation. A significant positive association was found between depressive symptoms and HE severity (P = .05). Depressive symptoms were significantly associated with fatigue (P < .001), daytime sleepiness (P < .001), general HRQOL (P < .001), and disease-specific HRQOL (P < .001). HE was significantly associated with fatigue (P = .02), general HRQOL (P < .001), and disease-specific HRQOL (P < .001). Depressive symptoms and HE were significant predictors of reduced HRQOL (P < .001), with depressive symptoms alone accounting for 58.8 % of the variance. Depressive symptoms and HE accounted for 68.0 % of the variance. Findings suggest a possible pathophysiological link between depression and HE in cirrhosis, and potentially a wider-reaching benefit of treating minimal and overt HE than previously appreciated.

Current management practices for hyponatremia (HN) are incompletely understood. The HN Registry has recorded diagnostic measures, utilization, efficacy, and outcomes of therapy for eu- or hypervolemic HN. To better understand current practices, we analyzed data from 3087 adjudicated adult patients in the registry with serum sodium concentration of 130 mEq/l or less from 225 sites in the United States and European Union. Common initial monotherapy treatments were fluid restriction (35%), administration of isotonic (15%) or hypertonic saline (2%), and tolvaptan (5%); 17% received no active agent. Median (interquartile range) mEq/l serum sodium increases during the first day were as follows: no treatment, 1.0 (0.0-4.0); fluid restriction, 2.0 (0.0-4.0); isotonic saline, 3.0 (0.0-5.0); hypertonic saline, 5.0 (1.0-9.0); and tolvaptan, 4.0 (2.0-9.0). Adjusting for initial serum sodium concentration with logistic regression, the relative likelihoods for correction by 5 mEq/l or more (referent, fluid restriction) were 1.60 for hypertonic saline and 2.55 for tolvaptan. At discharge, serum sodium concentration was under 135 mEq/l in 78% of patients and 130 mEq/l or less in 49%. Overly rapid correction occurred in 7.9%. Thus, initial HN treatment often uses maneuvers of limited efficacy. Despite an association with poor outcomes and availability of effective therapy, most patients with HN are discharged from hospital still hyponatremic. Studies to assess short- and long-term benefits of correction of HN with effective therapies are needed.

BACKGROUND AND AIM: Thrombocytopenia is frequently observed in patients with chronic hepatitis C virus (HCV) infection and cirrhosis, although it can also be observed in patients without cirrhosis by a virus-mediated phenomenon. This study assessed the prevalence, characteristics, and outcomes of antiviral therapy in patients with chronic HCV infection and thrombocytopenia not associated with cirrhosis. METHODS: The study included 1268 patients with HCV infection and thrombocytopenia enrolled in the phase 3 ENABLE studies that assessed the impact of eltrombopag on achieving a sustained virologic response to pegylated interferon and ribavirin. The study population was subdivided according to baseline FibroSURE test results into patients with non-cirrhosis (FibroSURE < 0.4) and cirrhosis-related (FibroSURE ≥ 0.75) thrombocytopenia. RESULTS: Compared with patients with cirrhosis-related thrombocytopenia (n = 995; 78.5%), non-cirrhotic patients with thrombocytopenia (n = 59; 4.6%) were younger (mean age [95% confidence interval (CI)]: 43.9 [40.7-47.2] vs 52.7 [52.2-53.3] years; P < 0.0001), predominantly female (64% [51-76] vs 30% [27-33]; P < 0.0001), and less frequently had a Model for End-Stage Liver Disease score ≥ 10 (24% [14-37] vs 45% [42-49]; P = 0.0012), low albumin levels (≤ 35 g/L; 2% [0-9] vs 32% [29-35]; P < 0.0001), and prevalence of diabetes mellitus (3% [0-12] vs 21% [19-24]; P = 0.0005). The sustained virologic response rate was higher in non-cirrhotic patients with thrombocytopenia (46% [95% CI, 33-59] vs 16% [14-18]; P < 0.0001). CONCLUSIONS: Patients with thrombocytopenia associated with HCV who have lower FibroSURE test results may have better preserved liver function and higher sustained virologic response rates than patients with cirrhosis.

Objectives: Hepatitis B virus (HBV) is endemic in West Africa. Because of immigration to the United States, screening and transition to long-term care is a significant public health concern. We describe the challenges of integrating individuals identified in a screening program into long-term care and the spectrum of disease severity. Methods: Between 2019 and 2023, 749 individuals were screened. Beginning 2022, all were offered a free serologic evaluation. Details of the previous diagnosis, HBV care, the serologic evaluation, aspartate aminotransferase to platelet ratio index, and Fibrosis index-4 scores were recorded. The results of transient elastography (TE) were correlated with the serologic evaluation. Results: A total of 75 (10%) individuals were hepatitis B surface antigen-positive, including 58 (77.3%) previously and 17 (22.7%) newly diagnosed. Despite attempts at linkage to care, only 14 (37.8%) of those diagnosed before the offer continued and/or entered long-term care. A total of 63 of 75 (84%) returned for the evaluation. Among 56 HBV treatment-naïve individuals, 66.1% had a serologic profile consistent with the carrier state. A total of 10 (18.2%) individuals met the criteria for HBV therapy, and 10 (21.7%) had ≥F2 fibrosis on TE. There was no correlation between aspartate aminotransferase to platelet ratio index and Fibrosis index-4 scores and TE. Eight (29.6%) of 27 patients with a profile of the HBV carrier state had ≥F2 fibrosis. Conclusion: Integration of individuals with HBV from West Africa identified in a screening program into long-term care is challenging. Inclusion of a serologic evaluation in programs for immigrant communities should be considered. Up to 30% of individuals with a serologic profile consistent with the HBV carrier state may have ≥F2 fibrosis.
RESUMO
Background: Hepatitis B (HBV) and hypertension (HTN) are prevalent in West Africa (WA). Inadequate control is common, and evaluation and management are challenging among immigrants due to unfamiliarity with the United States (US) healthcare system. While HBV is stigmatised, HTN is recognised as an important condition. We describe how a HTN screening program can facilitate HBV screening in the Bronx WA community. Methods: Thirty-minute HTN educational programs were delivered in collaboration with faith-based organisations, and 5-min presentations were presented upon request at community gatherings. Arrangements were made for those interested in a clinic visit where a questionnaire was completed, blood pressure (BP) measured, a free BP cuff provided, HBV testing performed, and referrals made. For those without ongoing care, insurance was arranged, and linkage to care provided. Findings: Seven 30-min and five 5-min presentations were conducted. After the 30-min presentation, 204 of 445 attendees (45.8%) requested a visit, and 68 (33.3%) attended the visit. After the 5-min presentation, 80 requested a visit and 51 (63.8%) attended the visit. A BP >140/90 mmHg was present in 122 individuals (48.4%), including 43 (17.1%) without a history of HTN and 39 (15.5%) with BP >160/90 mmHg. All except two who reported previous testing agreed to HBV testing. 19 (7.5%) were hepatitis B surface antigen positive. Transition into ongoing care was provided for 60 (33.9%) with HTN who were not integrated into the US healthcare system. Interpretation: HTN screening with a free BP cuff promotes HBV screening and US healthcare integration. Funding: No funding.
RESUMO
Background and Aims: Thrombocytopenia is present in up to 76% of patients with chronic liver disease, and lower platelet counts (PCs) are associated with greater severity of portal hypertension. In this study, we assess the relationship of PC in patients with a clinical diagnosis of severe alcoholic hepatitis (SAH) with clinical severity and response to corticosteroid (CS) therapy. Methods: Clinical characteristics, treatment, and hospital outcomes for patients admitted with SAH were analyzed from an electronic health record system. Patients were categorized based on admission PC (k/uL) into 5 categories: <50, 50-99, 100-149, 150-199, and ≥200. Frequency of complications (acute kidney injury, ascites, and hepatic encephalopathy), length of stay, and admission to an intensive care unit were analyzed across PC categories. Characteristics of patients who did and did not receive at least 4 days of CS therapy were compared. Results: Among 159 patients, 15 (9.4%) were in the PC < 50 category, 42 (26.4%) in PC 50-99, 51 (32%) in PC 100-149, 23 (14.5%) in PC 150-199, and 28 (17.6%) in PC ≥ 200. A higher admission PC was associated with greater white blood cell count, absolute neutrophil count, and total bilirubin (P < .05). Patients with higher PC on admission were more likely to receive steroids. PC was inversely associated with Lille score at treatment day 4 (P < .05). Conclusion: A higher PC in SAH was associated with a greater inflammatory response and total bilirubin. Patients with a higher PC were more likely to receive CS and have a favorable treatment response.
RESUMO
BACKGROUND: Hepatitis B virus (HBV) infection is endemic in West Africa. There has been a significant increase in the Bronx West African (WA) community. To achieve HBV elimination, vaccination of non-immune individuals is important. Unfortunately, vaccine uptake in immigrant populations is at this time very limited. METHODS: An educational program was conducted by medical providers of WA origin in collaboration with local faith-based organizations, after which free HBV screening was offered. Non-immune individuals were initially recommended to contact their medical provider or referred to the Department of Health for vaccination. Beginning in 2021, the program offered vaccination. A questionnaire including reasons for vaccination in the program was offered. FINDINGS: Among the first500 individuals screened,34.6 % required vaccination. Among those screened before program vaccine availability, 72.2 % initiated the vaccination series,with38.2 % obtainingit at an outside setting and34 % returning when available through the program.Among patients screened after program vaccineavailability, 92.1 % initiated the series.Of those receiving vaccination in the program and completing the questionnaire,70.7 % had access to care but chose vaccination by the program because of the trust instilled by WA personnel. INTERPRETATION: Our findings demonstrate the effectiveness of integrating vaccination into an HBV screening program for an immigrant population. It emphasizes the importance of timeliness and cultural sensitivity.

Background: Many residents of the Bronx are from West Africa where chronic hepatitis B is endemic. Hepatitis B screening is low in West African immigrant communities due to multiple possible cultural and socioeconomic factors. Methods: A culturally sensitive educational program on hepatitis B with a special emphasis on the relevance for the West African community was developed. Arrangements were made with leaders of West African faith-based organizations to conduct educational programs following religious services after which a survey was completed to assess changes in attitudes towards the infection and motivation for testing. Arrangements were then made for serologic testing at which time hypertension screening was also performed. Findings: Nine events in which a total of 550 people attended were held. Among the 339 (61.6%) participants who completed the questionnaire, 325 of the participants (95.1%) reported improved understanding, and 236 (67.0%) indicated greater comfort in sharing a meal and talking with an infected individual. Two hundred seventy-four participants (82.7%) indicated an intention to undergo testing, and 339 (97.8%) indicated that they would encourage family and friends to undergo screening. Three hundred thirty-two of the 550 participants (60.3%) requested serologic testing. Among those requesting testing, 224 (67.5%) underwent testing. Interpretation: A culturally sensitive educational program in collaboration with faith-based organizations is effective in motivating people from West Africa to undergo screening for hepatitis B at which time other preventative health care measures such as hypertension screening can be performed.

RESUMO
Thrombocytopenia is a frequent complication in patients with cirrhosis. As many as 84% of patients with cirrhosis have thrombocytopenia, and it is an independent variable indicative of advanced disease and poor prognosis. Although there is great concern that it may aggravate bleeding during surgical procedures, there is limited evidence to inform decisions regarding the treatment of cirrhotic patients with thrombocytopenia undergoing invasive procedures. Finally, there is evidence that platelets play a significant role in liver regeneration. In this report, the clinical implications of thrombocytopenia in cirrhotic patients are reviewed. The utility of platelet counts in the prognosis of cirrhosis and relationship to complications of advanced liver disease, including portal hypertension, esophageal varices, and hepatocellular carcinoma. The impact of low platelet counts on bleeding complications during invasive procedures is outlined. Finally, the role of platelets and potential adverse impact in liver regeneration is reviewed.
RESUMO
Aim: Treatment practices and effectiveness in cirrhotic patients with hyponatremia (HN) in the HN Registry were assessed. Methods: Characteristics, treatments, and outcomes were compared between patients with HN at admission and during hospitalization. For HN at admission, serum sodium concentration [Na] response was analyzed until correction to > 130 mmol/L, switch to secondary therapy, or discharge or death with sodium ≤ 130 mmol/L. Results: Patients with HN at admission had a lower [Na] and shorter length of stay (LOS) than those who developed HN (P < 0.001). Most common initial treatments were isotonic saline (NS, 36%), fluid restriction (FR, 33%), and no specific therapy (NST, 20%). Baseline [Na] was higher in patients treated with NST, FR, or NS versus hypertonic saline (HS) and tolvaptan (Tol) (P < 0.05). Treatment success occurred in 39%, 39%, 52%, 78%, and 81% of patients with NST, FR, NS, HS, and Tol, respectively. Relapse occurred in 55% after correction and was associated with increased LOS (9 versus 6 days, P < 0.001). 34% admitted with HN were discharged with HN corrected. Conclusions: Treatment approaches for HN were variable and frequently ineffective. Success was greatest with HS and Tol. Relapse of HN is associated with increased LOS.

BACKGROUND: Portal vein thrombosis (PVT) develops in cirrhotic patients because of stagnation of blood flow. Transjugular intrahepatic portosystemic shunt (TIPS) creates a low-resistance conduit that restores portal venous patency and blood flow. AIM: The effect of PVT on transplant-free survival in cirrhotic patients undergoing TIPS creation was evaluated. PATIENTS AND METHODS: A multicenter, retrospective cohort study of patients who underwent TIPS creation for cirrhotic portal hypertension was carried out. A Cox model with propensity score adjustment was developed to evaluate the effect of PVT on 90-day and 3-year transplant-free survival. A subgroup analysis examining mortality of those with superior and inferior PVT was also carried out. RESULTS: A total of 252 consecutive TIPS creations were assessed, including 65 in patients with PVT. Survival of patients with high Model for End-stage Liver Disease scores (≥18) and PVT was not statistically different compared with patients with low Model for End-stage Liver Disease scores (<18) and no PVT at 90 days (P=0.46) and 3 years (P=0.42). Those with superior PVT had improved 90-day and 3-year survival both compared with patients with a inferior PVT and those without a PVT (P<0.01, all cases). CONCLUSION: The presence of PVT does not impair the prognosis of patients following TIPS creation, particularly in patients with superior portal occlusion.

Hepatitis B virus (HBV) is the most common cause of chronic hepatitis and end-stage liver disease worldwide. Untreated, chronic hepatitis B acquired early in life results in cirrhosis, liver failure, or hepatocellular carcinoma in up to 40% of individuals. Until recently, the options for a patient who had end-stage hepatitis B cirrhosis were severely limited, but during the past 15 years great strides have been made in prevention and treatment of hepatitis B cirrhosis. This article reviews recent advances in the understanding of the natural history, prevention, and medical management of HBV-related end-stage liver disease.

There are multiple possible causes of ascites in patients with end-stage renal disease on hemodialysis therapy. In this report, we describe a patient with chronic hepatitis C infection who presented with refractory inflammatory ascites, along with cachexia, hypoalbuminemia, and erythropoietin resistance associated with the chronic inflammatory state induced by a failed kidney transplant. Evaluation showed only mild hepatic fibrosis, absence of portal hypertension, and no other identifiable cause of the ascites. Furthermore, the inflammatory ascites did not respond to antibiotic therapy, but promptly resolved, along with the other manifestations of the chronic inflammatory state, after transplant nephrectomy. This report describes a novel cause for refractory inflammatory ascites in a patient with a failed kidney transplant and emphasizes the importance of transplant nephrectomy.

Drug-induced injury (DILI) is a frequent cause of abnormal liver tests and a leading cause of liver failure in the United States. Colchicine has long been used as a systemic anti-inflammatory agent for treatment of gout by inhibiting mitotic activity and neutrophil function. We present the first case of colchicine-induced hepatoxicity, supported by histopathologic findings characteristic of colchicine-induced injury and resolution of liver enzyme abnormalities after its discontinuation. Colchicine-associated DILI has implications for the evaluation of patients with abnormal liver tests and gout, especially for patients with alcoholism and non-alcoholic fatty liver disease, in whom there is an increased incidence of gout.
RESUMO
Thrombocytopenia is the most common hematological abnormality encountered in patients with chronic liver disease (CLD). In addition to being an indicator of advanced disease and poor prognosis, it frequently prevents crucial interventions. Historically, thrombocytopenia has been attributed to hypersplenism, which is the increased pooling of platelets in a spleen enlarged by congestive splenomegaly secondary to portal hypertension. Over the past decade, however, there have been significant advances in the understanding of thrombopoiesis, which, in turn, has led to an improved understanding of thrombocytopenia in cirrhosis. Multiple factors contribute to the development of thrombocytopenia and these can broadly be divided into those that cause decreased production, splenic sequestration, and increased destruction. Depressed thrombopoietin levels in CLD, together with direct bone marrow suppression, result in a reduced rate of platelet production. Thrombopoietin regulates both platelet production and maturation and is impaired in CLD. Bone marrow suppression can be caused by viruses, alcohol, iron overload, and medications. Splenic sequestration results from hypersplenism. The increased rate of platelet destruction in cirrhosis also occurs through a number of pathways: increased shear stress, increased fibrinolysis, bacterial translocation, and infection result in an increased rate of platelet aggregation, while autoimmune disease and raised titers of antiplatelet immunoglobulin result in the immunologic destruction of platelets. An in-depth understanding of the complex pathophysiology of the thrombocytopenia of CLD is crucial when considering treatment strategies. This review outlines the recent advances in our understanding of thrombocytopenia in cirrhosis and CLD.
RESUMO
Autoimmune phenomena are common in patients with chronic hepatitis C. Management of chronic hepatitis C/autoimmune hepatitis syndrome has until recently been problematic due to the adverse effects of interferon on autoimmune processes and immunosuppression on viral replication. In this report we describe 3 patients with chronic hepatitis C/autoimmune hepatitis overlap syndrome who responded rapidly to direct acting anti-viral therapy. The resolution of the autoimmune process supports a direct viral role in its pathophysiology.
