Improvement of quality of care provided to outpatients with hepatic cirrhosis after an educational intervention.

OBJECTIVE: A set of indicators has been reported to measure the quality of care for cirrhotic patients, and previously published studies report variable adherence rates to these indicators. This study aimed to assess the quality of care provided to cirrhotic outpatients before and after an educational intervention by determining its impact on adherence to quality indicators. METHODS: We conducted a quasi-experimental, cross-sectional study including 324 cirrhotic patients seen in 2017 and 2019 at a tertiary teaching hospital in Spain. Quality indicators were assessed in five domains: documentation of cirrhosis etiology, disease severity assessment, hepatocellular carcinoma (HCC) screening, variceal bleeding prophylaxis, and vaccination. After identifying areas for improvement, an educational intervention was implemented. A second evaluation was performed after the intervention to assess changes in adherence rates. RESULTS: Before the intervention, adherence rates were excellent (>90%) for indicators related to variceal bleeding prophylaxis and documentation of cirrhosis etiology, acceptable (60-80%) for HCC screening and disease severity assessment, and poor (<50%) for vaccinations. After the educational intervention, there was a statistically significant improvement in adherence rates for eight indicators related to HCC screening (70-90%), disease severity assessment (90%), variceal bleeding prophylaxis (>90%), and vaccinations (60-90%). CONCLUSION: Our study demonstrates a significant improvement in the quality of care provided to cirrhotic outpatients after an educational intervention. The findings highlight the importance of targeted educational interventions to enhance adherence to quality indicators in the management of cirrhosis.

Clinical profile of Spanish hepatitisC virus-infected treatment-naïve patients with compensated cirrhosis in the CREST study. / Perfil clínico de los pacientes españoles con hepatitisC naïve con cirrosis compensada tratados en el estudio CREST.

BACKGROUND AND AIM OF THE STUDY: There are still patients with hepatitisC in Spain who have yet to be diagnosed, but their clinical profile is unclear. In 2021, 21.93% of patients diagnosed had cirrhosis and were mostly treatment-naïve. METHODS: This sub-analysis describes the clinical profile of the 60Spanish treatment-naïve patients with compensated cirrhosis who were included in the CREST study. MAJOR RESULTS: Sixty percent of patients were male, median age 56years, and 33% had a history of drug use. Almost three-quarters (71.3%) had more than one comorbidity and 78.3% took concomitant medication. At treatment initiation, median platelet count was 139×103/µL and FibroScan® 17kPa. No virological failure was observed and no patient discontinued treatment due to adverse events. No clinically significant changes were noted during or after treatment in the median platelet, albumin, bilirubin, and transaminase levels. CONCLUSIONS: Treatment with glecaprevir/pibrentasvir for 8weeks in this cohort of treatment-naïve patients with compensated cirrhosis in Spain was safe and effective. This information reinforces the use of this short antiviral regimen even when there is compensated cirrhosis, simplifying the approach to hepatitisC among those patients still to be diagnosed and treated in Spain.

Fatal case of HBV-liver failure after withdrawal of antiviral treatment.

We report a case of fatal HBV reactivation in a patient with chronic hepatitis B infection HBeAg-, who was withdrawn from antiviral therapy.. We think that it may be a warning of risks that this clinical decision may entail.

Alcohol-related liver disease phenotype impacts survival after an acute variceal bleeding episode.

BACKGROUND & AIMS: Alcohol-related hepatitis (AH) encompasses a high mortality. AH might be a concomitant event in patients with acute variceal bleeding (AVB). The current study aimed to assess the prevalence of AH in patients with AVB and to compare the clinical outcomes of AH patients to other alcohol-related liver disease (ALD) phenotypes and viral cirrhosis. METHODS: Multicentre, observational study including 916 patients with AVB falling under the next categories: AH (n = 99), ALD cirrhosis actively drinking (d-ALD) (n = 285), ALD cirrhosis abstinent from alcohol (a-ALD) (n = 227) and viral cirrhosis (n = 305). We used a Cox proportional hazards model to calculate adjusted hazard ratio (HR) of death adjusted by MELD. RESULTS: The prevalence of AH was 16% considering only ALD patients. AH patients exhibited more complications. Forty-two days transplant-free survival was worse among AH, but statistical differences were only observed between AH and d-ALD groups (84 vs. 93%; p = 0.005), when adjusted by MELD no differences were observed between AH and the other groups. At one-year, survival of AH patients (72.7%) was similar to the other groups; when adjusted by MELD mortality HR was better in AH compared to a-ALD (0.48; 0.29-0.8, p = 0.004). Finally, active drinkers who remained abstinent presented better survival, independently of having AH. CONCLUSIONS: Contrary to expected, AH patients with AVB present no worse one-year survival than other patients with different alcohol-related phenotypes or viral cirrhosis. Abstinence influences long-term survival and could explain these counterintuitive results.

Long-term use of somatostatin analogs for chronic gastrointestinal bleeding in hereditary hemorrhagic telangiectasia.

Background: Chronic bleeding due to gastrointestinal (GI) involvement in patients with hemorrhagic hereditary telangiectasia (HHT) can provoke severe anemia with high red blood cells (RBC) transfusion requirements. However, the evidence about how to deal with these patients is scarce. We aimed to assess the long-term efficacy and safety of somatostatin analogs (SA) for anemia management in HHT patients with GI involvement. Methods: This is a prospective observational study including patients with HHT and GI involvement attended at a referral center. SA were considered for those patients with chronic anemia. Anemia-related variables were compared in patients receiving SA before and during treatment. Patients receiving SA were divided into responders (patients with minimal hemoglobin levels improvement >10 g/L and maintaining hemoglobin levels ≥80 g/L during treatment), and non-responders. Adverse effects during follow-up were collected. Results: Among 119 HHT patients with GI involvement, 67 (56.3%) received SA. These patients showed lower minimal hemoglobin levels (73 [60-87] vs. 99 [70.2-122.5], p < 0.001), and more RBC transfusion requirements (61.2% vs. 38.5%, p = 0.014) than patients without SA therapy. Median treatment period was 20.9 ± 15.2 months. During treatment, there was a statistically significant improvement in minimum hemoglobin levels (94.7 ± 29.8 g/L vs. 74.7 ± 19.7, p < 0.001) and a reduction of patients with minimal hemoglobin levels <80 g/L (39 vs. 61%, p = 0.007) and RBC transfusions requirement (33.9% vs. 59.3%, p < 0.001). Sixteen (23.9%) patients showed mild adverse effects, mostly diarrhea or abdominal pain, leading to treatment discontinuation in 12 (17.9%) patients. Fifty-nine patients were eligible for efficacy assessment and 32 (54.2%) of them were considered responders. Age was associated with non-responder patients, OR 95% CI; 1.070 (1.014-1.130), p = 0.015. Conclusion: SA can be considered a long-term effective and safe option for anemia management in HHT patients with GI bleeding. Older age is associated with poorer response.

Hepatic encephalopathy is not a contraindication to pre-emptive TIPS in high-risk patients with cirrhosis with variceal bleeding.

BACKGROUND: A pre-emptive transjugular intrahepatic portosystemic shunt (pTIPS) reduces mortality in high-risk patients with cirrhosis (Child-Pugh C/B+active bleeding) with acute variceal bleeding (AVB). Real-life studies point out that <15% of patients eligible for pTIPS ultimately undergo transjugular intrahepatic portosystemic shunt (TIPS) due to concerns about hepatic encephalopathy (HE). The outcome of patients undergoing pTIPS with HE is unknown. We aimed to (1) assess the prevalence of HE in patients with AVB; (2) evaluate the outcome of patients presenting HE at admission after pTIPS; and (3) determine if HE at admission is a risk factor for death and post-TIPS HE. PATIENTS AND METHODS: This is an observational study including 2138 patients from 34 centres between October 2011 and May 2015. Placement of pTIPS was based on individual centre policy. Patients were followed up to 1 year, death or liver transplantation. RESULTS: 671 of 2138 patients were considered at high risk, 66 received pTIPS and 605 endoscopic+drug treatment. At admission, HE was significantly more frequent in high-risk than in low-risk patients (39.2% vs 10.6%, p<0.001). In high-risk patients with HE at admission, pTIPS was associated with a lower 1-year mortality than endoscopic+drug (HR 0.374, 95% CI 0.166 to 0.845, p=0.0181). The incidence of HE was not different between patients treated with pTIPS and endoscopic+drug (38.2% vs 38.7%, p=0.9721), even in patients with HE at admission (56.4% vs 58.7%, p=0.4594). Age >56, shock, Model for End-Stage Liver Disease score >15, endoscopic+drug treatment and HE at admission were independent factors of death in high-risk patients. CONCLUSION: pTIPS is associated with better survival than endoscopic treatment in high-risk patients with cirrhosis with variceal bleeding displaying HE at admission.

Perioperative Complications and Long-Term Follow-Up of Liver Transplantation in Hemorrhagic Hereditary Telangiectasia: Report of Three Cases and Systematic Review.

The aim was to describe three patients with hemorrhagic hereditary telangiectasia (HHT) requiring liver transplantation (LT) and to perform a systematic review focusing on surgical complications and long-term follow-up. Unrestricted searches of the Medline and Embase databases were performed through February 2022. Forty-five studies were selected including 80 patients plus the three new reported patients, 68 (81.9%) were female and mean age was 50 (27-72) years. Main indications for LT were high-output cardiac failure (n = 40; 48.2%), ischemic cholangitis (n = 19; 22.9%), and a combination of both conditions (n = 13;15.6%). Mean cold ischemic time and red blood cell units transfused during LT were 554 (300-941) minutes and 11.4 (0-88) units, respectively. Complications within 30 days were described in 28 (33.7%) patients, mainly bleeding complications in 13 patients, hepatic artery (HA) thrombosis in four and hepatic vein thrombosis in one. Mean follow-up was 76.4 (1-288) months, and during it, four new patients developed thrombotic complications in HA, HA aneurysm, celiac artery, and the portal-splenic-mesenteric vein. HHT relapse in the transplant allograft was detected in 13 (17.1%) patients after 1-19 years (including two fatal recurrences). Overall mortality was 12%. In conclusion, previous assessment of HA anatomy and hyperdynamic circulatory state could reduce LT complications. The risk of relapse in the hepatic graft supports a multidisciplinary follow-up for HHT patients with LT.

Detection of anti-mitochondrial 2-oxoacid dehydrogenase complex subunit's antibodies for the diagnosis of primary biliary cholangitis.

Anti-mitochondrial antibodies (AMA), directed against the E2 subunits of the 2-oxo acid dehydrogenase complexes, are markers of Primary Biliary Cholangitis (PBC), a chronic autoimmune liver disease. However, the clinical significance of subunits-specific AMA type PDC-E2 -E2 subunit of the pyruvate dehydrogenase complex-, BCOADC-E2 -E2 subunit of the branched-chain 2-oxo acid dehydrogenase complex-, OGDC-E2 -E2 subunit of the 2-oxo-glutarate dehydrogenase complex- and nPDC -native pyruvate dehydrogenase complex (M2-AMA) . Is not well known, and not all AMA specificities are associated with PBC. The aim of the study was to show the usefulness of the number and combination of subunits-specific AMA positive for the diagnosis of PBC. We detected AMA by indirect immunofluorescence (IIF-AMA) and M2-AMA by dot-blot. We studied the relationship of AMA with some clinical and laboratory variables in 307 patients (37% PBC) with positive dot-blot for M2-AMA. In PBC patients, we detected different E2 subunits of the 2-oxo acid dehydrogenase complexes antibodies (M2-AMA): 82.9% were specific for nPDC, 64.5% for PDC-E2, 44.4% for BCOADC-E2, and 9.6% for OGDC-E2. IIF and dot-blot tests achieved a Area Under the Receiver Operating Characteristic Curve (ROC AUC) of 0.674 (1: 320 cut-off titer, Sensibility (Se) 64.7%, Specificity (Sp) 63.4%) and 0.663 (three specificities M2-AMA, Se 43%, Sp 81.2%), respectively. The detection of different E2 subunits of the 2-oxo acid dehydrogenase complexes antibodies (M2-AMA) by dot-blot showed different ROC AUC: anti-PDC-E2 showed an AUC of 0.610, a Se of 43.7%, and a Sp of 76.4%. Finally, the combined detection of nPDC/BCOADC-E2/PDC-E2 reached an AUC of 0.6095, a Se of 59.6%, and a Sp of 70.2%.The identification of two M2-AMA specificities through dot-blot increased PBC odds ratio (OR) by 2.05 (p:0.031), as compared to the identification of one specificity. Moreover, the identification of three and four specificities increased OR by 4.63 (p:0.000) and by 21.53 (p:0.006), respectively. nPDC/OGDC-E2/PDC-E2 and nPDC/OGDC-E2/BCOADC-E2/PDC-E2 combinations increased PBC OR by 10.04 (p:0.034), as compared to any other combination. 1:320 and 1:640 IIF-AMA increased PBC OR by 4.93 (p:0.009) and 7.67 (p:0.001), respectively, as compared to IIF-AMA titers equal to or less than 1:160. M2-AMA dot-blot was less sensitive but more specific than IIF-AMA, with similar predictive capacity for PBC. Increased numbers of M2-AMA specificities clearly increased the risk of PBC. Some combinations were strongly related to PBC (nPDC/BCOADC-E2/PDC-E2), but others were not (one single M2-AMA, and nPDC plus PDC-E2). M2-AMA dot-blot was less sensitive but more specific than IIF-AMA, with similar predictive capacity for PBC. Increased numbers of M2-AMA specificities clearly increased the risk of PBC, being some combinations, such as nPDC/BCOADC-E2/PDC-E2, more related to PBC than others. Finally, the determination of the number of M2-AMA specificities was more useful than the particular subunit target for PBC diagnosis. In conclusion, the study of the number of M2-AMA specificities by dot-blot should definitely be considered for PBC diagnosis.

Bacterial infections in patients with acute variceal bleeding in the era of antibiotic prophylaxis.

BACKGROUND & AIMS: Antibiotic prophylaxis reduces the risk of infection and mortality in patients with cirrhosis and acute variceal bleeding (AVB). This study examines the incidence of, and risk factors for, bacterial infections during hospitalization in patients with AVB on antibiotic prophylaxis. METHODS: A post hoc analysis was performed using the database of an international, multicenter, observational study designed to examine the role of pre-emptive transjugular intrahepatic portosystemic shunts in patients with cirrhosis and AVB. Data were collected on patients with cirrhosis hospitalized for AVB (n = 2,138) from a prospective cohort (October 2013-May 2015) at 34 referral centers, and a retrospective cohort (October 2011-September 2013) at 19 of these centers. The primary outcome was incidence of bacterial infection during hospitalization. RESULTS: A total of 1,656 patients out of 1,770 (93.6%) received antibiotic prophylaxis; third-generation cephalosporins (76.2%) and quinolones (19.0%) were used most frequently. Of the patients on antibiotic prophylaxis, 320 patients developed bacterial infection during hospitalization. Respiratory infection accounted for 43.6% of infections and for 49.7% of infected patients, and occurred early after admission (median 3 days, IQR 1-6). On multivariate analysis, respiratory infection was independently associated with Child-Pugh C (odds ratio [OR] 3.1; 95% CI 1.4-6.7), grade III-IV encephalopathy (OR 2.8; 95% CI 1.8-4.4), orotracheal intubation for endoscopy (OR 2.6; 95% CI 1.8-3.8), nasogastric tube placement (OR 1.7; 95% CI 1.2-2.4) or esophageal balloon tamponade (OR 2.4; 95% CI 1.2-4.9). CONCLUSION: Bacterial infections develop in almost one-fifth of patients with AVB despite antibiotic prophylaxis. Respiratory infection is the most frequent, is an early event after admission, and is associated with advanced liver failure, severe hepatic encephalopathy and use of nasogastric tube, orotracheal intubation for endoscopy or esophageal balloon tamponade. LAY SUMMARY: Bacterial infections develop during hospitalization in close to 20% of patients with acute variceal bleeding despite antibiotic prophylaxis. Respiratory bacterial infections are the most frequent and occur early after admission. Respiratory infection is associated with advanced liver disease, severe hepatic encephalopathy and a need for a nasogastric tube, orotracheal intubation for endoscopy or esophageal balloon tamponade.

A notable proportion of liver transplant candidates with alcohol-related cirrhosis can be delisted because of clinical improvement.

BACKGROUND & AIMS: To what extent patients with alcohol-related decompensated cirrhosis can improve until recovery from decompensation remains unclear. We aimed to investigate the probability of recovery and delisting due to improvement in patients with alcohol-related decompensated cirrhosis on the waiting list (WL) for liver transplantation (LT). METHODS: We conducted a registry-based, multicenter, retrospective study including all patients admitted to the LT WL in Catalonia (Spain) with the indication of alcohol-, HCV-, cholestasis- or non-alcoholic steatohepatitis-related decompensated cirrhosis between January 2007 and December 2018. Competing-risk analysis was used to investigate variables associated with delisting due to improvement in patients with alcohol-related decompensated cirrhosis. Criteria for delisting after improvement were not predefined. Outcomes of patients after delisting were also studied. RESULTS: One-thousand and one patients were included, 420 (37%) with alcohol-related decompensated cirrhosis. Thirty-six (8.6%) patients with alcohol-related decompensated cirrhosis were delisted after improvement at a median time of 29 months after WL admission. Lower model for end-stage liver disease (MELD) score, higher platelets and either female sex or lower height were independently associated with delisting due to improvement, while time of abstinence did not reach statistical significance in multivariate analysis (p = 0.055). Five years after delisting, the cumulative probability of remaining free from liver-related death or LT was 76%, similar to patients with HCV-related decompensated cirrhosis delisted after improvement. CONCLUSIONS: A significant proportion of LT candidates with alcohol-related cirrhosis can be delisted due to improvement, which is predicted by low MELD score and higher platelet count at WL admission. Women also have a higher probability of being delisted after improvement, partially due to reduced early access to LT for height discrepancies. Early identification of patients with potential for improvement may avoid unnecessary transplants. LAY SUMMARY: Patients with alcohol-related cirrhosis can improve until being delisted in approximately 9% of cases. Low model for end-stage liver disease score and high platelet levels at admission predict delisting after improvement, and women have higher probabilities of being delisted due to improvement. Long-term outcomes after delisting are generally favorable.

Rebleeding and mortality risk are increased by ACLF but reduced by pre-emptive TIPS.

BACKGROUND & AIMS: The relationship between acute-on-chronic liver failure (ACLF) and acute variceal bleeding (AVB) is poorly understood. Specifically, the prevalence and prognosis of ACLF in the context of AVB is unclear, while the role of transjugular intrahepatic portosystemic shunt (TIPS) in the management in patients with ACLF has not been described to date. METHODS: A multicenter, international, observational study was conducted in 2,138 patients from 34 centers between 2011 and 2015. ACLF was defined and graded according to the EASL-CLIF consortium definition. Placement of pre-emptive TIPS (pTIPS) was based on individual center policy. Patients were followed-up for 1 year, until death or liver transplantation. Cox regression and competing risk models (Gray's test) were used to identify independent predictors of rebleeding or mortality. RESULTS: At admission, 380/2,138 (17.8%) patients had ACLF according to EASL-CLIF criteria (grade 1: 38.7%; grade 2: 39.2%; grade 3: 22.1%). The 42-day rebleeding (19% vs. 10%; p <0.001) and mortality (47% vs. 10%; p <0.001) rates were higher in patients with ACLF and increased with ACLF grades. Of note, the presence of ACLF was independently associated with rebleeding and mortality. pTIPS placement improved survival in patients with ACLF at 42 days and 1 year. This effect was also observed in propensity score matching analysis of 66 patients with ACLF, of whom 44 received pTIPs and 22 did not. CONCLUSIONS: This large multicenter international real-life study identified ACLF at admission as an independent predictor of rebleeding and mortality in patients with AVB. Moreover, pTIPS was associated with improved survival in patients with ACLF and AVB. LAY SUMMARY: Acute variceal bleeding is a deadly complication of liver cirrhosis that results from severe portal hypertension. This study demonstrates that the presence of acute-on-chronic liver failure (ACLF) is the strongest predictor of mortality in patients with acute variceal bleeding. Importantly, patients with ACLF and acute variceal (re)bleeding benefit from pre-emptive (early) placement of a transjugular intrahepatic portosystemic shunt.

Ulcer bleeding after band ligation of esophageal varices: Risk factors and prognosis.

BACKGROUND: Post-banding ulcer bleeding is a rare complication of endoscopic band ligation of esophageal varices with high morbidity and mortality. There exist no management guidelines for this complication. AIMS: To determine the incidence, outcome and risk factors of post-banding ulcer bleeding. METHODS: Data for cirrhotic patients with acute variceal bleeding during a six-year period were prospectively collected, and all band ligation sessions performed were retrospectively analyzed. Demographic, analytic and endoscopic data were recorded, as well as complications, outcome and management of each episode of post-banding ulcer bleeding. RESULTS: The study includes 521 band ligation sessions performed on 175 patients. There were 24 cases of post-banding ulcer bleeding in 21 patients (incidence 4.6%). Independent risk factors for post-banding ulcer bleeding were MELD score, hepatocellular carcinoma and total beta-blocker dose. Mortality during the bleeding episode was 23.8%. Active bleeding or adherent clots at the time of endoscopy was associated with treatment failure or death. CONCLUSIONS: Post-banding ulcer bleeding is an uncommon but severe complication of esophageal banding. Patients with hepatocellular carcinoma, poor liver function and a low beta-blocker dose have higher risk of post-banding ulcer bleeding. An aggressive treatment should be considered in case of active bleeding at endoscopy.

Deep-sequencing reveals broad subtype-specific HCV resistance mutations associated with treatment failure.

A percentage of hepatitis C virus (HCV)-infected patients fail direct acting antiviral (DAA)-based treatment regimens, often because of drug resistance-associated substitutions (RAS). The aim of this study was to characterize the resistance profile of a large cohort of patients failing DAA-based treatments, and investigate the relationship between HCV subtype and failure, as an aid to optimizing management of these patients. A new, standardized HCV-RAS testing protocol based on deep sequencing was designed and applied to 220 previously subtyped samples from patients failing DAA treatment, collected in 39 Spanish hospitals. The majority had received DAA-based interferon (IFN) α-free regimens; 79% had failed sofosbuvir-containing therapy. Genomic regions encoding the nonstructural protein (NS) 3, NS5A, and NS5B (DAA target regions) were analyzed using subtype-specific primers. Viral subtype distribution was as follows: genotype (G) 1, 62.7%; G3a, 21.4%; G4d, 12.3%; G2, 1.8%; and mixed infections 1.8%. Overall, 88.6% of patients carried at least 1 RAS, and 19% carried RAS at frequencies below 20% in the mutant spectrum. There were no differences in RAS selection between treatments with and without ribavirin. Regardless of the treatment received, each HCV subtype showed specific types of RAS. Of note, no RAS were detected in the target proteins of 18.6% of patients failing treatment, and 30.4% of patients had RAS in proteins that were not targets of the inhibitors they received. HCV patients failing DAA therapy showed a high diversity of RAS. Ribavirin use did not influence the type or number of RAS at failure. The subtype-specific pattern of RAS emergence underscores the importance of accurate HCV subtyping. The frequency of "extra-target" RAS suggests the need for RAS screening in all three DAA target regions.

Endoscopic biliary drainage in unresectable biliary obstruction: the role of endoscopic ultrasound-guidance in a cohort study

Background and study aims: the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) has increased in cases of failed endoscopic retrograde cholangiopancreatography (ERCP) and there are some concerns. The main aim of the study was to determine the role of EUS-BD in a palliative case cohort. The secondary aim was to compare the efficacy, safety and survival of EUS-BD and ERCP procedures. Patients and methods: this was an observational study at a single tertiary institution, with a consecutive inclusion from January 2015 to December 2016. The inclusion criteria were unresectable tumors of the biliopancreatic region with an indication of BD. Statistical comparison analysis was performed between the ERCP and EUS-BD groups. The incidence between groups was compared using the Chi-square and Fisher exact tests. The log rank test was used to compare the risk of death. Results: fifty-two cases with an indication of palliative BD were included in the study. Transpapillary drainage via ERCP was possible in 44 procedures and EUS-BD was required in eight cases; 15.4% of the cohort and seven using lumen apposing metal stent (LAMS). The technical and clinical success of global endoscopic BD was 100% and 88.5% (ERCP: 84.6% and 78.9%; EUS-BD: 100% and 62.5%, respectively). Pancreatitis was the most frequent adverse event (AE) in the ERCP group (9.62%) and bleeding in the EUS-BD (25%). There were fatal AEs in ERCP (1.9%) and EUS-BD (25%) cases. Patient survival was higher with ERCP transpapillary stents compared to EUS-guided stents, which was statistically significant (p = 0.007). Conclusions: the requirement of EUS-BD in palliative biliopancreatic pathology is not marginal. EUS-BD is associated with a lower survival rate and a higher rate of fatal AE, which argues against its use as a first choice procedure

Tratamiento de la telangiectasia hemorrágica hereditaria en el paciente adulto / Medical management of haemorrhagic hereditary telangiectasia in adult patients

La telangiectasia hemorrágica hereditaria es una enfermedad minoritaria con herencia autosómica dominante que ocasiona un crecimiento vascular anómalo de forma sistémica. El abordaje y seguimiento de estos pacientes debería hacerse desde unidades multidisciplinares. Su diagnóstico es clínico según los criterios de Curaçao. Las telangiectasias en la mucosa nasal ocasionan epistaxis recurrentes, principal síntoma de esta enfermedad y de difícil control. Los 3 patrones de afectación hepática, comunicaciones entre arteria hepática y venas suprahepáticas, entre arteria hepática y vena porta o entre vena porta y venas suprahepáticas pueden causar insuficiencia cardiaca por hiperaflujo, hipertensión portal o encefalopatía hepática, respectivamente. Estos tipos de afectación vascular se pueden establecer mediante tomografía computarizada. Se debe realizar un cribado de fístulas arteriovenosas pulmonares a todos los pacientes mediante una ecocardiografía con contraste. Nuestro principal objetivo es realizar una revisión del manejo de las epistaxis, afectación hepática y pulmonar del paciente adulto con telangiectasia hemorrágica hereditaria

Hereditary haemorrhagic telangiectasia (HHT) is an autosomal dominant inherited Rare Disease that causes a systemic anomalous vascular overgrowth. The approach and follow-up of these patients should be from multidisciplinary units. Its diagnosis is carried out according to Curaçao clinical Criteria. Telangiectasia in the nasal mucosa cause recurrent epistaxis, the main symptom of HHT and difficult to control. The three types of hepatic shunting, hepatic artery to hepatic vein, hepatic artery to portal vein or to portal vein to hepatic vein, can cause high-output heart failure, portal hypertension or porto-systemic encephalopathy, respectively. These types of vascular involvement can be established using computerised tomography. Pulmonary arteriovenous fistula should be screened for all HHT patients by contrast echocardiography. The main objective is to review the management of epistaxis, liver and lung involvement of the adult patient with HHT

Manejo de la insuficiencia hepática aguda grave. Documento de posicionamiento de la Societat Catalana de Digestologia / Management of acute liver failure. Clinical guideline from the Catalan Society of Digestology

La insuficiencia hepática aguda grave es una enfermedad infrecuente de etiología diversa caracterizada por la rápida aparición de insuficiencia hepatocelular grave en individuos sin enfermedad hepática previa. El manejo inicial de esta enfermedad condiciona su evolución posterior. El primer contacto con el paciente afecto de insuficiencia hepática aguda grave suele realizarse en unidades de urgencias, consultas de aparato digestivo o, en casos más graves, unidades de cuidados intensivos. En todos estos casos resulta fundamental un abordaje multidisciplinario que incluya cirujanos y hepatólogos expertos en esta enfermedad, es decir, de centros hospitalarios que dispongan de programa de trasplante hepático. El presente artículo revisa la evidencia actual en el manejo médico de la insuficiencia hepática aguda grave, desde la sospecha diagnóstica y el manejo inicial, hasta el tratamiento médico intensivo, incluyendo la necesidad de un trasplante hepático urgente. También se revisan las evidencias sobre el uso de sistemas de soporte hepático artificial en esta enfermedad

Acute liver failure is an uncommon and severe disease characterised by a rapid onset of severe hepatocellular failure in individuals without previous liver disease. Initial management of this entity determines the outcome of the patient. Initial contact with the acute liver failure patients usually occurs in the emergency department, digestology clinic or, in more severe cases, intensive care units. The management of acute liver failure patients in all these cases must be multidisciplinary, involving surgeons and hepatologists who are experts in this condition, meaning those from hospitals with active liver transplant programmes. This article reviews the current body of evidence concerning the medical management of acute liver failure patients, from the suspected diagnosis and initial management to intensive medical treatment, including the need for an emergency liver transplantation. Moreover, we also review the use of artificial liver support systems in this setting

Factors influencing hepatitis C cure in the era of direct-acting antivirals. / Factores que influyen en la curación de la hepatitis C en la era de los antivirales de acción directa.

Direct-acting antiviral agents are highly potent drugs with a strong genetic barrier. Consequently, the factors influencing hepatitis C cure have been reduced and have progressively lost importance. Host factors, such as the presence of cirrhosis, race, and treatment adherence, influence sustained viral response. Adherence, together with treatment errors and drug interactions, are also important, especially in older patients. Viral factors, such as viral load, genotype, and the presence of baseline resistances affect the response rate but their influence can be minimised by using pan-genotypic regimens. Treatment simplification and the high efficacy of new antiviral treatments will allow treatment universalisation and will hopefully enable elimination of the infection in the next few decades.
