Recurrent Variceal Bleeding In Patients Research Articles

Safety of Nonselective Beta-Blockers in Decompensated Liver Cirrhosis and Their Role in Inducing Hepatorenal Syndrome.

Background Nonselective beta-blockers (NSBBs) have been used in the management of portal hypertension and the prevention of initial and recurrent variceal bleeding in patients with liver cirrhosis. However, there is controversy regarding the use of NSBBs in patients with decompensated cirrhosis (DC) due to concerns over potential adverse effects, such as worsening of hepatic function and risk of hepatorenal syndrome (HRS). HRS is a serious complication of DC characterized by acute kidney injury (AKI) and progressive renal failure, and its development can lead to significant morbidity and mortality in this setting. Therefore, using NSBBs in patients with DC remains an area of ongoing research and debate. Our study aims to investigate the potential effect of NSBBs on HRS development. Methodology A retrospective chart review of 404 patients with cirrhosis was performed across all Northwell Health institutions between January 01, 2019, and December 31, 2020. An analysis was done on 516 patient encounters. Inclusion criteria included patients with an established International Classification of Diseases 10th Revision code of cirrhosis and AKI.After adjusting for clinical predictors, the Student's t-test or Mann-Whitney U-testwas used to compare variables between the two outcome groups (HRS vs. no HRS) for the continuous variables. Pearson's chi-square test or Fisher's exact test was used for the categorical variablesto test if an association existed between the use of NSBBs at home and HRS. A two-sided p-value <0.05 was considered statistically significant. SAS 9.4 (SAS Institute Inc., Cary, NC, USA) was used for statistical analysis. Results The primary outcome was the development of HRS during the hospital stay. With a total of 109 visits with HRS, we had 21 (23.60%) reported HRS in the 89 visits where NSBBs were used at home before the hospitalization, while 88 (20.61%) HRS were observed in the 427 visits with no NSBB use at home. The use of NSBBs at home was not significantly associated with the development of HRS (odds ratio = 1.1, 95% confidence interval = 0.6-1.9, p = 0.7321). We also found that higher serum albumin on admission is associated with lower odds of HRS. In contrast, increased serum creatinine, bilirubin, presence of ascites, and use of pressors were associated with a higher risk of HRS. Conclusions Our study highlights the relevant safety of NSBB use in end-stage liver disease. Their use did not appear to increase the risk of developing HRS during hospitalization with DC. Further randomized controlled trials are warranted to shed more light on the efficacy, dose tolerance limits, and safety of NSBBs in decompensated end-stage liver disease.

Transjugular intrahepatic portosystemic shunt and splenectomy are more effective than endoscopic therapy for recurrent variceal bleeding in patients with idiopathic noncirrhotic portal hypertension.

BACKGROUNDTransjugular intrahepatic portosystemic shunt (TIPS), splenectomy plus esophagogastric devascularization (SED) and endoscopic therapy + non-selective β-blockers (ET + NSBB) are widely applied in secondary prevention of recurrent gastroesophageal variceal bleeding in patients with liver cirrhosis. These different treatments, however, have not been compared in patients with idiopathic non-cirrhotic portal hypertension (INCPH).AIMTo compare the outcomes of TIPS, SED and ET + NSBB in the control of variceal rebleeding in patients with INCPH.METHODSThis retrospective study recruited patients from six centers across China. Demographic characteristics, baseline profiles and follow-up clinical outcomes were collected. Post-procedural clinical outcomes, including incidence of rebleeding, hepatic encephalopathy (HE), portal vein thrombosis (PVT) and mortality rates, were compared in the different groups.RESULTSIn total, 81 patients were recruited, with 28 receiving TIPS, 26 SED, and 27 ET + NSBB. No significant differences in demographic and baseline characteristics were found among these three groups before the procedures. After treatment, blood ammonia was significantly higher in the TIPS group; hemoglobin level and platelet count were significantly higher in the SED group (P < 0.01). Rebleeding rate was significantly higher in the ET + NSBB group (P < 0.01). Mortality was 3.6%, 3.8% and 14.8% in the TIPS, SED and ET + NSBB groups, respectively, with no significant differences (P = 0.082). Logistic regression analysis showed that mortality was significantly correlated with rebleeding, HE, portal thrombosis and superior mesenteric vein thrombosis (P < 0.05).CONCLUSIONIn patients with INCPH, TIPS and SED were more effective in controlling rebleeding than ET + NSBB, but survival rates were not significantly different among the three groups. Mortality was significantly correlated with rebleeding, HE and PVT.

Complications of liver cirrhosis - pharmaceutical versus interventional therapy

The prognosis of patients with liver cirrhosis is impaired by complications such as variceal bleeding, ascites, hepatorenal syndrome, hepatic encephalopathy and hepatocellular carcinoma. A steadily increasing array of treatment options for these complications is available, including pharmaceutical treatment (e. g. beta blockers for varices or diuretics for ascites), endoscopic treatment (e. g. band ligation of varices), radiological interventions (e. g. transjugular shunt, transarterial chemoembolization) and liver transplantation. Most of the complications occur due to portal hypertension. Therefore, decompressive treatment by implantation of a transjugular intrahepatic portosystemic shunt (TIPS) an effective therapeutic option for many complications of liver cirrhosis. Its main indications are acute and recurrent variceal bleeding in patients with advanced disease as well as refractory ascites. The TIPS does not affect options of abdominal surgery and may therefore be used as a bridge to liver transplantation.

EFFICACY OF CARVEDILOL COMBINED WITH ENDOSCOPIC VARICEAL LIGATION IN THE PREVENTION OF RECURRENT VARICEAL BLEEDING IN PATIENTS OF CIRRHOSIS

Background: The recurrent variceal bleeding is still very high with a very poor prognosis. The combination of a non-selective beta-blocker and endoscopic variceal ligation (EVL) is still a standard therapy for the prevention, but many patients showed no response to propranolol. Carvedilol is a new, non-selective beta-blocker having intrinsic alpha-blocker activity, but the data about the efficacy and safety of carvedilol is still very limited. This study is aimed at assessing the efficacy and safety of carvedilol combined with EVL in the prevention of recurrent variceal bleeding. Patients and methods: 33 patients having variceal bleeding were enrolled. All patients received carvedilol and were performed the EVL until variceal eradication. All the patients were followed after 9 months. Results: rate of variceal eradication of oesophageal varices was 87.88%; the recurrence rate of variceal bleeding was 12.12% after 9 months. The side effects of carvedilol were rare and not severe, including vertiges, headache, and orthostatic hypertension. Conclusion: Carvedilol combined with EVL appeared as a relatively safe and effective in the prevention of recurrent variceal bleeding in patients of cirrhosis. Key words: carvedilol, variceal bleeding, EVL

Outcome of the Pediatric Patients with Portal Cavernoma: The Retrospective Study for 10 Years Focusing on Recurrent Variceal Bleeding.

Background. Portal cavernoma (PC) is the most critical condition with risk or variceal hemorrhage in pediatric patients. We retrospectively investigated the patients with PC focusing on the predictors for recurrent variceal bleeding. Methods. Between July 2003 and June 2013, we retrospectively enrolled all consecutive patients admitted to our department with a diagnosis of PC without abdominal malignancy or liver cirrhosis. The primary endpoint of this observational study was recurrent variceal bleeding. Independent predictors of recurrent variceal bleeding were identified using the logistic regression model. Results. A total of 157 patients were enrolled in the study. During the follow-up period, 24 patients exhibited onset of recurrent variceal bleeding. Acute variceal bleeding was subjected to conservative symptomatic treatment and emergency endoscopic sclerotherapy. Surgical procedure selection was based on the severity of vascular dilation and collateral circulation. Multivariate logistic regression analysis demonstrated that the presence of ascites, collateral circulation, and portal venous pressure were independent prognostic factors of recurrent variceal bleeding for patients with portal cavernoma. Conclusions. The presence of ascites, collateral circulation, and portal venous pressure evaluation are important and could predict the postsurgical recurrent variceal bleeding in patients with portal cavernoma.

Obstruktion chirurgischer portosystemischer Shunts in der frühen postoperativen Phase: Interventionelle Behandlung durch Angioplastie und Stentimplantation

Recurrent variceal bleeding in patients treated with surgical porto-systemic shunting is most often due to shunt stenoses or occlusion. Radiological interventional procedures are a possible method of therapy and our experience herein is described in this report. From 1997 to 1999 54 patients with recurrent variceal bleeding were treated with a surgical porto-systemic shunt procedure. Of these early shunt occlusion occurred in 5 patients, which was treated with percutaneous transcatheter techniques. In only one patient was PTA alone sufficient to reestablish shunt patency, in four patient stent placement was necessary in addition. In the follow-up period 1 patient died 26 month after intervention with (autopsy-proven) patent shunt, in one patient shunt reocclusion occurred after 11 months and in 3 patients the shunt is still patent. PTA, if necessary in combination with stent placement, is an attractive alternative method of therapy in case of an early surgical porto-systemic shunt occlusion.

Surgical portosystemic shunts for treatment of portal hypertensive bleeding: Outcome and effect on liver function

Background: Since the advent of liver transplantation and transjugular intrahepatic portosystemic shunts (TIPS), the role of surgical portosystemic shunts in the treatment of portal hypertension has changed. However, we have continued to use portosystemic shunts in patients with noncirrhotic portal hypertension and in patients with Child's A cirrhosis. Methods: We performed 48 surgical portosystemic shunt procedures between 1988 and 1998. The outcomes of these patients were evaluated to assess the efficacy of this treatment. Data from 39 of 48 patients were available for analysis. The average follow-up was 42 months. Results: Liver function generally remained stable for the patients; only 2 patients had progressive liver failure and required transplant procedures. Gastrointestinal bleeding (3 patients), encephalopathy (3 patients), and shunt thrombosis (3 patients) were rare. Patient survival was 81% at 4 years, similar to survival with liver transplantation (P = .22). Conclusions: Surgical shunts remain the treatment of choice for prevention of recurrent variceal bleeding in patients with good liver function and portal hypertension. (Surgery 1999; 126:708-13.)

A Controlled Trial of Oral Propranolol Compared With Injection Sclerotherapy for the Long–Term Magnagement of Variceal Bleeding

This trial was carried out to assess the value of propranolol for the prevention of recurrent variceal bleeding in patients with well-compensated cirrhosis. We also compared propranolol therapy to long-term injection sclerotherapy. One hundred and eight patients, in whom the original variceal hemorrhage stopped spontaneously (before diagnostic endoscopy) and without sclerotherapy or surgical intervention, were included. All were Pugh grade A or B; 55% had alcoholic cirrhosis. Patients were chosen randomly to receive oral propranolol (in a dosage to reduce resting pulse rate by 25%) or to undergo long-term injection sclerotherapy. In both groups, episodes of repeat bleeding that did not stop spontaneously were managed with sclerotherapy. Patients considered to have failed propranolol therapy were treated with long-term sclerotherapy. Follow-up ranged from 12 to 64 mo. In the propranolol group, 28 (54%) of the 52 patients had repeat bleeding from varices with a total of 57 episodes; 14 received long-term sclerotherapy. In the sclerotherapy group, 25 (45%) of the 56 patients had repeat bleeding, with a total of 40 episodes (p less than 0.20). On an intention-to-treat basis, the risk of bleeding expressed per patient-month of follow-up was similar for the two groups, at 0.05 and 0.037, respectively. Survival as assessed by cumulative life analysis was also similar, with 55% and 66% alive at 3 yr (p less than 0.40). Stepwise regression analysis of possible factors predicting further bleeding in patients taking propranolol selected only two variables--the pretreatment pulse rate and the extent of pulse-rate reduction in response to propranolol.(ABSTRACT TRUNCATED AT 250 WORDS)

Endoscopic Variceal Sclerosis Compared with Distal Splenorenal Shunt To Prevent Recurrent Variceal Bleeding in Cirrhosis

To define the roles of endoscopic variceal sclerosis and distal splenorenal shunt in the prevention of recurrent variceal bleeding in patients with cirrhosis. A prospective, randomized clinical trial with crossover for those failing therapy. The median follow-up was 61 months. A private, tertiary-referral university hospital. Seventy-two patients fulfilling inclusion criteria were drawn from a total of 420 patients treated during a 4.5-year interval. Endoscopic variceal sclerosis or distal splenorenal shunt. Survival was significantly (P = 0.02) improved in patients randomly assigned to receive sclerotherapy: 13 of these 37 (35%) patients failed sclerotherapy and required surgical rescue. A survival advantage (P = 0.01) was seen in patients with alcoholic cirrhosis who had this combined therapy; however, in patients with nonalcoholic cirrhosis, survival for those receiving sclerotherapy and surgical rescue was not significantly (P = 0.36) different from that of patients receiving distal splenorenal shunt. Control of variceal bleeding was significantly (P less than 0.001) better in the distal splenorenal shunt group (34 of 35 [97%] compared with 15 of 37 [41%] in the sclerotherapy group). Using death, uncontrolled rebleeding, or shunt thrombosis as the endpoints resulted in no significant difference between treatment groups. Hepatocyte function and portal perfusion were significantly better maintained in patients with alcoholic cirrhosis who were managed by sclerotherapy rather than shunt (P = 0.01 and P = 0.001, respectively). Endoscopic sclerotherapy with surgical rescue for uncontrolled bleeding is the optimum therapy for patients with alcoholic cirrhosis and variceal bleeding. Survival is similar in nonalcoholic patients treated with either distal splenorenal shunt or endoscopic sclerotherapy, but shunting provides better control of variceal bleeding.

Controlled trial of propranolol to prevent recurrent variceal bleeding in patients with non-cirrhotic portal fibrosis.

Fifty patients with non-cirrhotic portal fibrosis who were admitted to hospital because of upper gastrointestinal bleeding were randomly assigned to treatment with either oral propranolol given in doses that reduced the resting pulse rate by 25% (25 patients) or with a placebo (25 patients). One year after the start of the study 20 patients in the propranolol group and five patients in the placebo group were free from recurrent gastrointestinal bleeding (p less than 0.0001). Giving continuous oral propranolol treatment is therefore effective in preventing recurrent upper gastrointestinal bleeding in patients with non-cirrhotic portal fibrosis.
