Endoscopic Ultrasound for the Treatment of Gastric Variceal Bleeding in a Patient with Portal Cavernoma

"A 30-year-old lady was admitted with two weeks of fever and right upper quadrant pain. She had a background of non-malignant, non-cirrhotic portal vein thrombosis (PVT) with cavernoma formation. There was no detected underlying pro-thrombotic condition. She had established portal hypertension with esophageal varices. Her portal cavernoma was complicated by portal biliopathy and concurrent gallstone disease - with an endoscopic retrograde cholangio-pancreatography (ERCP) and stenting four weeks prior to admission. Drug history included carvedilol for primary prophylaxis of bleeding, anticoagulation had not been undertaken due to collateralisation. Admission computerised tomography (CT) revealed multiple small liver abscesses with a patent biliary stent and no progression of PVT and she was treated conservatively with intravenous antibiotics."--Case summary and discussionAlexander Boyd (1, 2, 3), Brinder S Mahon (2), Neil Rajoriya (2, 3) ; 1.

Protocol for a case-control prospective study to investigate the impact of Hepatic Encephalopathy on Nutritional Intake and Sarcopenia status in patients with end-stage LIVer disease:HENS-LIV study

INTRODUCTION: Hepatic encephalopathy (HE) is a debilitating symptom of end-stage liver disease (ESLD), but there remains a paucity of evidence regarding its impact on nutritional status, nutritional intake, compliance with nutritional support and resultant muscle health and function. Malnutrition and sarcopenia are associated with increased morbidity and mortality in patients with ESLD. The aim of the current case–control study is to prospectively investigate the impact of HE on nutritional intake and sarcopenia status in patients with ESLD. METHODS AND ANALYSIS: Patients with ESLD, with HE (n=10) and without HE (n=10) will be recruited at the outpatient liver unit, University Hospital Birmingham, UK. All patients will undergo clinical assessment at baseline and again at 6–8 weeks (in-line with their routine clinical follow-up), to assess the impact of HE on reported nutritional intake, nutritional status and sarcopenia/physical functional status. Standard medical, dietetic and home-based exercise physiotherapy care will continue for all participants as determined by their clinical team. Two methods of assessing nutritional intake will include the 24-hour food recall and 3-day food diaries. Assessment of sarcopenia status will be undertaken using anthropometry (mid-arm muscle circumference (MAMC)) and ultrasound imaging of the quadriceps muscle group. Markers of physical function (hand grip strength; chair rise time), frailty (Liver Frailty Index (LFI)), physical activity (accelerometery) and exercise capacity (Duke Activity Status Index (DASI)) will be assessed at both clinic visits. ETHICS AND DISSEMINATION: The study is approved by Wales Research Ethics Committee 2 and Health Research Authority (REC reference: 21/WA/0216). Recruitment into the study commenced November 2021. The findings will be disseminated through peer-reviewed publications and international presentations. TRIAL REGISTRATION NUMBER: RRK7156

Circulating myeloid populations have prognostic utility in alcohol-related liver disease

Introduction: Alcohol-related liver disease (ARLD) accounts for over one third of all deaths from liver conditions, and mortality from alcohol-related liver disease has increased nearly five-fold over the last 30 years. Severe alcohol-related hepatitis almost always occurs in patients with a background of chronic liver disease with extensive fibrosis or cirrhosis, can precipitate ‘acute on chronic’ liver failure and has a high short-term mortality. Patients with alcohol-related liver disease have impaired immune responses, and increased susceptibility to infections, thus prompt diagnosis of infection and careful patient management is required. The identification of early and non-invasive diagnostic and prognostic biomarkers in ARLD remains an unresolved challenge. Easily calculated predictors of infection and mortality are required for use in patients who often exhibit variable symptoms and disease severity and may not always present in a specialized gastroenterology unit.Methods: We have used a simple haematological analyser to rapidly measure circulating myeloid cell parameters across the ARLD spectrum.Results and Discussion: We demonstrate for the first time that immature granulocyte (IG) counts correlate with markers of disease severity, and our data suggests that elevated counts are associated with increased short-term mortality and risk of infection. Other myeloid populations such as eosinophils and basophils also show promise. Thus IG count has the potential to serve alongside established markers such as neutrophil: lymphocyte ratio as a simply calculated predictor of mortality and risk of infectious complications in patients with alcohol-related hepatitis. This would allow identification of patients who may require more intensive management

Comparable Overall Survival in Patients with Hepatocellular Carcinoma Diagnosed within and outside a Surveillance Programme:The Potential Impact of Liver Cirrhosis

Hepatocellular carcinoma (HCC) is the third leading cause of cancer death, and its incidence is rising. Mortality from HCC is predicted to increase by 140% by 2035. Surveillance of high-risk patients with cirrhosis or chronic liver disease may be one means of reducing HCC mortality, but the level of supporting evidence for international guidelines is low/moderate. This study explores the real-world experience of HCC surveillance at a tertiary referral centre. Electronic patient records for all new HCCs diagnosed between August 2012 and December 2021 were retrospectively reviewed. Patient and tumour characteristics were evaluated, including the co-existence of chronic liver disease, cancer treatment and survival, and categorised according to HCC diagnosis within or outside a surveillance programme. Patients with HCC who presented through surveillance had smaller tumours diagnosed at an earlier stage, but this did not translate into improved overall survival. All patients in surveillance had chronic liver disease, including 91% (n = 101) with cirrhosis, compared to 45% (n = 29) in the non-surveillance cohort. We propose that the immune dysfunction associated with cirrhosis predisposes patients to a more aggressive tumour biology than the largely non-cirrhotic population in the non-surveillance group

Duke Activity Status Index and Liver Frailty Index predict mortality in ambulatory patients with advanced chronic liver disease:A prospective, observational study

BACKGROUND: There remains a lack of consensus on how to assess functional exercise capacity and physical frailty in patients with advanced chronic liver disease (CLD) being assessed for liver transplantation (LT). Aim To investigate prospectively the utility of the Duke Activity Status Index (DASI) and Liver Frailty Index (LFI) in ambulatory patients with CLD.AIM: To investigate prospectively the utility of the Duke Activity Status Index (DASI) and Liver Frailty Index (LFI) in ambulatory patients with CLD.METHODS: We recruited patients from outpatient clinics at University Hospitals Birmingham, UK (2018-2019). We prospectively collated the DASI and LFI to identify the prevalence of, respectively, functional capacity and physical frailty, and to evaluate their accuracy in predicting overall and pre-LT mortality.RESULTS: We studied 307 patients (57% male; median age 54 years; UKELD 52). Median DASI score was 28.7 (IQR 16.2-50.2), mean LFI was 3.82 (SD = 0.72), and 81% were defined either 'pre-frail' or 'frail'. Female sex and hyponatraemia were significant independent predictors of both DASI and LFI. Age and encephalopathy were significant independent predictors of LFI, while BMI significantly predicted DASI. DASI and LFI were significantly related to overall (HR 0.97, p = 0.001 [DASI], HR 2.04, p = 0.001 [LFI]) and pre-LT mortality (HR 0.96, p = 0.02 [DASI], HR 1.94, p = 0.04 [LFI]).CONCLUSIONS: Poor functional exercise capacity and physical frailty are highly prevalent among ambulatory patients with CLD who are being assessed for LT. The DASI and LFI are simple, low-cost tools that predict overall and pre-LT mortality. Implementation of both should be considered in all outpatients with CLD to highlight those who may benefit from targeted nutritional and exercise interventions.</p

Portal hypertension in polycystic liver disease patients does not affect wait-list or immediate post-liver transplantation outcomes

AIM: To establish the impact of portal hypertension (PH) on wait-list/post-transplant outcomes in patients with polycystic liver disease (PCLD) listed for liver transplantation. METHODS: A retrospective single-centre case controlled study of consecutive patients listed for liver transplantation over 12 years was performed from our centre. PH in the PCLD cohort was defined by the one or more of following parameters: (1) presence of radiological or endoscopic documented varices from our own centre or the referral centre; (2) splenomegaly (> 11 cm) on radiology in absence of splenic cysts accounting for increased imaging size; (3) thrombocytopenia (platelets < 150 × 10(9)/L); or (4) ascites without radiological evidence of hepatic venous outflow obstruction from a single cyst. RESULTS: Forty-seven PCLD patients (F: M = 42: 5) were listed for liver transplantation (LT) (single organ, n = 35; combined liver-kidney transplantation, n = 12) with 19 patients (40.4%) having PH. When comparing the PH group with non-PH group, the mean listing age (PH group, 50.6 (6.4); non-PH group, 47.1 (7.4) years; P = 0.101), median listing MELD (PH group, 12; non-PH group, 11; P = 0.422) median listing UKELD score (PH group, 48; non-PH group, 46; P = 0.344) and need for renal replacement therapy (P = 0.317) were similar. In the patients who underwent LT alone, there was no difference in the duration of ICU stay (PH, 3 d; non-PH, 2 d; P = 0.188), hospital stay length (PH, 9 d; non-PH, 10 d; P = 0.973), or frequency of renal replacement therapy (PH, 2/8; non-PH, 1/14; P = 0.121) in the immediate post-transplantation period. CONCLUSION: Clinically apparent portal hypertension in patients with PCLD listed for liver transplantation does not appear to have a major impact on wait-list or peri-transplant morbidity
