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.

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.

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.

Preemptive-TIPS Improves Outcome in High-Risk Variceal Bleeding: An Observational Study.

Patients admitted with acute variceal bleeding (AVB) and Child-Pugh C score (CP-C) or Child-Pugh B plus active bleeding at endoscopy (CP-B+AB) are at high risk for treatment failure, rebleeding, and mortality. A preemptive transjugular intrahepatic portosystemic shunt (p-TIPS) has been shown to improve survival in these patients, but its use in clinical practice has been challenged and not routinely incorporated. The present study aimed to further validate the role of preemptive TIPS in a large number of high-risk patients. This multicenter, international, observational study included 671 patients from 34 centers admitted for AVB and high risk of treatment failure. Patients were managed according to current guidelines, and use of drugs and endoscopic therapy (D+E) or p-TIPS was based on individual center policy. p-TIPS in the setting of AVB is associated with a lower mortality in CP-C patients compared with D+E (1 year mortality 22% vs. 47% in D+E group; P = 0.002). Mortality rate in CP-B+AB patients was low, and p-TIPS did not improve it. In CP-C and CP-B+AB patients, p-TIPS reduced treatment failure and rebleeding (1-year cumulative incidence function probability of remaining free of the composite endpoint: 92% vs. 74% in the D+E group; P = 0.017) and development of de novo or worsening of previous ascites without increasing rates of hepatic encephalopathy. Conclusion: p-TIPS must be the treatment of choice in CP-C patients with AVB. Because of the strong benefit in preventing further bleeding and ascites, p-TIPS could be a good treatment strategy for CP-B+AB patients.

The irritable bowel syndrome care process from the patients´ and professionals´ views.

BACKGROUND AND PURPOSE OF THE STUDY: This study assessed the experiences of irritable bowel syndrome patients with the healthcare system. Specifically, this study focused on the barriers that patients found. METHODS: Three focus groups were conducted with the participation of 19 patients and 10 healthcare professionals. From this information a script of questions was designed and 33 structured interviews were conducted. Finally, a scale for evaluation of the perception of patients was designed for primary care (14 items) and gastroenterology (13 items). Internal consistency and construct validity were calculated. RESULTS: The difficulties of accessibility, to clarify doubts, concerns regarding uncertainty, reduced information about prognosis and its social and labour effects were the most cited by patients. Low adherence and persistence in the treatment plan were the problems cited most often by professionals. The items of the scale for primary care were grouped into 4 factors (explained variance, 73%), while those for gastroenterology were grouped into 3 factors (explained variance, 67%). The internal consistency was 0.84 and 0.82, respectively. A total of 29 (88%) patients were satisfied with the care provided in gastroenterology, while 24 (73%) declared themselves satisfied with the primary care physician (Chi-square 2.4, p = 0.21). This study was carried out from November 2013 to July 2014. CONCLUSIONS: This study describes the most relevant problems in the assistance received by these patients.

[Recommendations of the Spanish Pancreatic Club on the diagnosis and treatment of chronic pancreatitis: part 2 (treatment)]. / Recomendaciones del Club Español Pancreático para el diagnóstico y tratamiento de la pancreatitis crónica: parte 2 (tratamiento).

Chronic pancreatitis (CP) is a complex disease with a wide spectrum of clinical manifestations ranging from asymptomatic disease to disabling forms or serious complications. The management of CP frequently differs among geographical areas and even among centers. These differences are due to the scarcity of high-quality studies and clinical practice guidelines that focus on the diagnosis and treatment of this disease. The aim of the Spanish Pancreatic Club was to create evidence-based recommendations for the management of CP. Two coordinators chose a multidisciplinary panel of 24 experts in this disease. These experts were selected on the basis of their clinical and research experience in CP. A list of questions was drawn up and each question was then reviewed by two panelists. These questions were then used to produce a draft, which was discussed in a face-to-face meeting with all the participants. Levels of evidence were based on the classification of the Oxford Centre for Evidence-Based Medicine. In the second part of the consensus process, recommendations were established for the management of pain, pseudocysts, biliary and duodenal stenosis, pancreatic fistula and ascites, left portal hypertension, diabetes mellitus, exocrine pancreatic insufficiency, and nutritional support in CP.

[Treatment of refractory hepatic encephalopathy associated with insertion of a transjugular intrahepatic portosystemic shunt through new endovascular techniques: a case report]. / Tratamiento de la encefalopatía hepática resistente asociada a la creación de una derivación percutánea portosistémica intrahepática mediante nuevas técnicas endovasculares: a propósito de un caso clínico.

Insertion of a transjugular intrahepatic portosystemic shunt (TIPS) is an increasingly used treatment in the management of the complications of portal hypertension. However, one of the complications of this technique is refractory or recurrent hepatic encephalopathy, which poses a difficult clinical problem. We report the case of a patient who underwent TIPS insertion to control bleeding due to esophageal varices. The patient subsequently developed refractory hepatic encephalopathy, requiring reduction of the caliber of the shunt.

Usefulness of surveillance programmes for early diagnosis of hepatocellular carcinoma in clinical practice.

BACKGROUND/AIMS: Surveillance programmes (SPs) for hepatocellular carcinoma (HCC) in patients with cirrhosis intend to diagnose the tumour in its early stages when an effective therapy can be applied. The aims of this study have been to compare the survival of patients with HCC being diagnosed or not in SPs, and to establish a more accurate profile of the best target population. METHODS: From January 1996 to June 2005, 290 patients with HCC were included. The relationship between being diagnosed or not in an SP and survival has been analysed in a univariate analysis. Pretreatment variables found to be significant predictors of survival in univariate analysis were included in a multivariate analysis. RESULTS: The mean survival for patients diagnosed in SPs (27 months, 16.6-37.4) was significantly longer than in patients being diagnosed out of these programmes (6 months, 2.6-9.4) (P=0.001). Child-Pugh class A [beta 1.4, 95% confidence interval (CI) 1.14-1.78; P=0.0002] and being diagnosed in SPs (beta 0.4, 95% CI 0.3-0.6; P=0.0003) became the only independent predictive factors of longer survival. CONCLUSIONS: SPs for HCC allow the detection of small tumours and the application of intention-to-cure therapies, which improves survival. However, these programmes do not improve prognosis in patients with advanced cirrhosis.

[Acute liver failure in a patient with hairy cell leukemia]. / Fallo hepático agudo en un paciente con tricoleucemia.

Acute liver failure as a manifestation of primary non-Hodkin's lymphoma is a rare phenomenon with a fatal prognosis. Hairy cell leukemia (HCL) is an uncommon chronic B-cell lymphoproliferative disorder, representing about 2 percent of all leukemies. We report a 78-year-old patient with a history of hairy cell leukemia since 10 years, presenting whith fulminant liver failure due to massive liver infiltration. He have reviewed several cases of infiltration of the liver by haematological malignancies, but we only have found after a review in MEDLINE between 1980 and 2006, one case of acute liver failure in a patient with hepatic invasion by hairy cell leukaemia.

Acute effects of dipyrone on renal function in patients with cirrhosis: a randomized controlled trial.

Use of non-steroidal anti-inflammatory drugs in cirrhosis has been associated with impairment of renal function based on its ability to inhibit the renal production of prostaglandins. Renal effects of dipyrone in patients with cirrhosis have not been evaluated. We aimed to assess the renal effect of therapeutic doses of dipyrone used for short periods of time in patients with cirrhosis. Twenty-nine patients with cirrhosis were included in an observer-blind clinical trial. Patients were randomized to receive three times a day oral acetaminophen (500 mg; N = 15) or dipyrone (575 mg; N = 14) for 72 hr. Serum and urine samples were obtained at baseline, 48 and 72 hr, and cystatin C, creatinine, aldosterone, 6-keto-Prostaglandin-F1 alpha and prostaglandin E2 were measured. Cystatin C and creatinine levels remained comparable in patients treated with acetaminophen and dipyrone. Urine and serum prostaglandins concentrations were significantly decreased at 72 hr in patients treated with dipyrone regardless of the status of ascites. One patient with ascites treated with dipyrone required a paracentesis and developed renal insufficiency. We conclude that dipyrone and acetaminophen did not reduce renal function when used for short periods of time (up to 72 hr) in patients with cirrhosis. However, considering that dipyrone lowered renal vasodilator prostaglandins synthesis, acetaminophen appears as the safest choice with respect to kidney function in cirrhosis.

Acute and chronic hemodynamic changes after propranolol in patients with cirrhosis under primary and secondary prophylaxis of variceal bleeding: a pilot study.

BACKGROUND AND AIM: Prophylactic treatment of variceal bleeding in cirrhotic patients with beta-blockers is effective in only some patients. Our aim was to determine whether the response of the hepatic venous pressure gradient (HVPG) to the intravenous administration of propranolol predicts the response after chronic oral propranolol treatment. PATIENTS AND METHODS: We included prospectively cirrhotic patients with esophageal varices under primary prophylaxis (PP) and secondary prophylaxis (SP). The HVPG was measured at baseline and after a propranolol bolus (0.15 mg/kg intravenous). A patient was considered a good-responder if HVPG decreased to 12 mmHg or 20% from baseline. Patients then received oral propranolol (heart rate titrated). Poor-responders under SP were also included in a variceal band ligation program. After at least 3 months, a second hemodynamic study was conducted. RESULTS: Fifty-six patients were included (36 SP and 20 PP). Response rate was similar (32.1 and 41.9%, P=0.7) and the Pearson's correlation coefficient was 0.61 (P=0.001). In 81.4% patients, the first study predicted the response status of the second. Six patients rebled on follow-up between the studies, all of them were poor responders to intravenous propranolol. CONCLUSION: A single hemodynamic study using intravenous propranolol seems to predict chronic response to propranolol.

Comparison of staging systems to predict survival in hepatocellular carcinoma.

PURPOSE: Some new staging systems in hepatocellular carcinoma (HCC) have been described in the last years. The aim of this study was to compare the survival-predicting capacity of some variables and the prognostic classifications. METHODS: Demographic, clinical, analytical variables and tumour characteristics were collected in a study including 115 patients with HCC. Predictors of survival were identified using the Kaplan-Meier test and the Cox model. Comparison between different staging systems was carried out. RESULTS: The 1-, 2- and 3-year estimated survival was 65%, 45% and 30%, respectively. Child-Pugh score and alpha-fetoprotein level greater than 400 UI/l were independent predictors of survival in the Cox model. Although all systems correctly differentiated between patients regarding survival (Kaplan-Meier, log rank < 0.05 for all), the Barcelona Clinic Liver Cancer (BCLC) showed a better discriminatory ability than the other evaluated scores. In addition, the independent homogenizing ability and stratification value of BCLC was better than that of other systems. On the contrary, model for end-stage liver disease (MELD) showed the worst results. CONCLUSIONS: Child-Pugh score and alpha-fetoprotein levels were the only independent predictors of survival in patients with HCC. Child-Pugh score showed a better prediction value for survival when compared with MELD. BCLC is more accurate than the other prognostic models evaluated in this investigation.
