[Medical societies in Germany call for a ban on flavors in e-cigarettes - A Position Paper of the German Respiratory Society (DGP) in cooperation with other professional associations and organizations]. / Medizinische Fachgesellschaften fordern ein Verbot von Aromen in E-Zigaretten.

E-cigarettes are primarily used by teenagers and young adults. Flavors in e-cigarettes increase their attractiveness and encourage young people and adults to start using them. This exposes young people in particular to the risk of nicotine addiction and various toxic substances from the aerosol of e-cigarettes. There are indications that various flavors in e-cigarettes are harmful to health, although toxicological studies are still lacking for the majority of flavors. There is a need for independent scientific investigations in this area. The scientific societies involved are calling for a ban on flavors in e-cigarettes, a ban on disposable e-cigarettes, effective regulation of the sale of e-cigarettes and effective control and implementation of the provisions for the protection of minors.

Intestinal Oxalate Absorption, Enteric Hyperoxaluria, and Risk of Urinary Stone Formation in Patients with Crohn's Disease.

Nephrolithiasis is a common urologic manifestation of Crohn's disease. The purpose of this study was to investigate the clinical characteristics, intestinal oxalate absorption, and risk factors for urinary stone formation in these patients. In total, 27 patients with Crohn's disease and 27 healthy subjects were included in the present study. Anthropometric, clinical, and 24 h urinary parameters were determined, and the [13C2]oxalate absorption test was performed. Among all patients, 18 had undergone ileal resection, 9 of whom had a history of urinary stones. Compared to healthy controls, the urinary excretion values of calcium, magnesium, potassium, sulfate, creatinine, and citrate were significantly lower in patients with Crohn's disease. Intestinal oxalate absorption, the fractional and 24 h urinary oxalate excretion, and the risk of calcium oxalate stone formation were significantly higher in patients with urolithiasis than in patients without urolithiasis or in healthy controls. Regardless of the group, between 83% and 96% of the [13C2]oxalate was detected in the urine within the first 12 h after ingestion. The length of ileum resection correlated significantly with the intestinal absorption and urinary excretion of oxalate. These findings suggest that enteric hyperoxaluria can be attributed to the hyperabsorption of oxalate following extensive ileal resection. Oral supplementation of calcium and magnesium, as well as alkali citrate therapy, should be considered as treatment options for urolithiasis.

Improving primary prophylaxis of variceal bleeding by adapting therapy to the clinical stage of cirrhosis. A competing-risk meta-analysis of individual participant data.

BACKGROUND & AIMS: Non-selective ß-blockers (NSBBs) and endoscopic variceal-ligation (EVL) have similar efficacy preventing first variceal bleeding. Compensated and decompensated cirrhosis are markedly different stages, which may impact treatment outcomes. We aimed to assess the efficacy of NSBBs vs EVL on survival in patients with high-risk varices without previous bleeding, stratifying risk according to compensated/decompensated stage of cirrhosis. METHODS: By systematic review, we identified RCTs comparing NSBBs vs EVL, in monotherapy or combined, for primary bleeding prevention. We performed a competing-risk, time-to-event meta-analysis, using individual patient data (IPD) obtained from principal investigators of RCTs. Analyses were stratified according to previous decompensation of cirrhosis. RESULTS: Of 25 RCTs eligible, 14 failed to provide IPD and 11 were included, comprising 1400 patients (656 compensated, 744 decompensated), treated with NSBBs (N = 625), EVL (N = 546) or NSBB+EVL (N = 229). Baseline characteristics were similar between groups. Overall, mortality risk was similar with EVL vs. NSBBs (subdistribution hazard-ratio (sHR) = 1.05, 95% CI = 0.75-1.49) and with EVL + NSBBs vs either monotherapy, with low heterogeneity (I2 = 28.7%). In compensated patients, mortality risk was higher with EVL vs NSBBs (sHR = 1.76, 95% CI = 1.11-2.77) and not significantly lower with NSBBs+EVL vs NSBBs, without heterogeneity (I2 = 0%). In decompensated patients, mortality risk was similar with EVL vs. NSBBs and with NSBBs+EVL vs. either monotherapy. CONCLUSIONS: In patients with compensated cirrhosis and high-risk varices on primary prophylaxis, NSBBs significantly improved survival vs EVL, with no additional benefit noted adding EVL to NSBBs. In decompensated patients, survival was similar with both therapies. The study suggests that NSBBs are preferable when advising preventive therapy in compensated patients.

[A correspondence in Munich: Karl Valentin and Ferdinand Sauerbruch]. / Eine Korrespondenz in München: Karl Valentin und Ferdinand Sauerbruch.

Karl Valentin, one of Germany's greatest comic talents, and the surgeon Ferdinand Sauerbruch probably met in Munich about 100 years ago. Their correspondence is outlined. Another encounter some years later in Berlin has been documented. Sauerbruch was one of many physicians whom Valentin consulted because of his fragile health, especially his "mood depressions." Sauerbruch, himself plagued by mood swings, but as a surgeon not actually responsible for such illnesses, meets this special person with empathy.

TIPS prevents further decompensation and improves survival in patients with cirrhosis and portal hypertension in an individual patient data meta-analysis.

BACKGROUND & AIMS: Further decompensation represents a prognostic stage of cirrhosis associated with higher mortality compared with first decompensation. A transjugular intrahepatic portosystemic shunt (TIPS) is indicated to prevent variceal rebleeding and for refractory ascites, but its overall efficacy to prevent further decompensations is unknown. This study assessed the incidence of further decompensation and mortality after TIPS vs. standard of care (SOC). METHODS: Controlled studies assessing covered TIPS compared with SOC for the indication of refractory ascites and prevention of variceal rebleeding published from 2004 to 2020 were considered. We collected individual patient data (IPD) to perform an IPD meta-analysis and to compare the treatment effect in a propensity score (PS)-matched population. Primary outcome was the incidence of further decompensation and the secondary outcome was overall survival. RESULTS: In total, 3,949 individual patient data sets were extracted from 12 controlled studies and, after PS matching, 2,338 patients with similar characteristics (SOC = 1,749; TIPS = 589) were analysed. The 2-year cumulative incidence function of further decompensation in the PS-matched population was 0.48 (95% CI 0.43-0.52) in the TIPS group vs. 0.63 (95% CI 0.61-0.65) in the SOC group (stratified Gray's test, p <0.0001), considering mortality and liver transplantation as competing events. The lower further decompensation rate with TIPS was confirmed by adjusted IPD meta-analysis (hazard ratio 0.44; 95% CI 0.37-0.54) and was consistent across TIPS indication subgroups. The 2-year cumulative survival probability was higher with TIPS than with SOC (0.71 vs. 0.63; p = 0.0001). CONCLUSIONS: The use of TIPS for refractory ascites and for prevention of variceal rebleeding reduces the incidence of a further decompensation event compared with SOC and increases survival in highly selected patients. IMPACT AND IMPLICATIONS: A further decompensation (new or worsening ascites, variceal bleeding or rebleeding, hepatic encephalopathy, jaundice, hepatorenal syndrome-acute kidney injury and spontaneous bacterial peritonitis) in patients with cirrhosis is associated with a poor prognosis. Besides the known role of TIPS in portal hypertension-related complications, this study shows that TIPS is also able to decrease the overall risk of a further decompensation and increase survival compared with standard of care. These results further support the role of TIPS in the management of patients with cirrhosis and portal hypertension-related complications.

Trends and the course of liver cirrhosis and its complications in Germany: Nationwide population-based study (2005 to 2018).

BACKGROUND: Cirrhosis is known to have a high prevalence and mortality worldwide. However, in Europe, the epidemiology of cirrhosis is possibly undergoing demographic changes, and etiologies may have changed due to improvements in standard of care. The aim of this population-based study was to analyze the trends and the course of liver cirrhosis and its complications in recent years in Germany. METHODS: We analyzed the data of all hospital admissions in Germany within diagnosis-related groups from 2005 to 2018. The diagnostic records of cirrhosis and other categories of diseases were based on ICD-10-GM codes. The primary outcome measurement was in-hospital mortality. Trends were analyzed through Poisson regression of annual number of admissions. The impact of cirrhosis on overall in-hospital mortality were assessed through the multivariate multilevel logistic regression model adjusted for age, sex, and comorbidities. FINDINGS: Of the 248,085,936 admissions recorded between 2005 and 2018, a total of 2,302,171(0•94%) were admitted with the diagnosis of cirrhosis, mainly as a comorbidity. Compared with other chronic diseases, patients admitted with cirrhosis were younger, mainly male and had the highest in-hospital mortality rate. Diagnosis of cirrhosis was an independent risk factor of in-hospital mortality with the highest odds ratio (OR:6•2[95%CI:6.1-6•3]) among all diagnoses. The prevalence of non-alcoholic fatty liver disease has increased four times from 2005 to 2018, while alcoholic cirrhosis is 20 times than other etiologies. Bleeding was found to be decreasing over time, but ascites remained the most common complication and was increasing. INTERPRETATION: This nationwide study demonstrates that cirrhosis represents a considerable healthcare burden, as shown by the increasing in-hospital mortality, also in combination with other chronic diseases. Alcohol-related cirrhosis and complications are on the rise. More resources and better management strategies are warranted. FUNDING: The funders had no influence on this study.

Beta-blockers in patients with liver cirrhosis: Pragmatism or perfection?

With increasing decompensation, hyperdynamic circulatory disturbance occurs in liver cirrhosis despite activation of vasoconstrictors. Here, the concept of a therapy with non-selective beta-blockers was established decades ago. They lower elevated portal pressure, protect against variceal hemorrhage, and may also have pleiotropic immunomodulatory effects. Recently, the beneficial effect of carvedilol, which blocks alpha and beta receptors, has been highlighted. Carvedilol leads to "biased-signaling" via recruitment of beta-arrestin. This effect and its consequences have not been sufficiently investigated in patients with liver cirrhosis. Also, a number of questions remain open regarding the expression of beta-receptors and its intracellular signaling and the respective consequences in the intra- and extrahepatic tissue compartments. Despite the undisputed role of non-selective beta-blockers in the treatment of liver cirrhosis, we still can improve the knowledge as to when and how beta-blockers should be used in which patients.

Bile Acids, Liver Cirrhosis, and Extrahepatic Vascular Dysfunction.

The bile acid pool with its individual bile acids (BA) is modulated in the enterohepatic circulation by the liver as the primary site of synthesis, the motility of the gallbladder and of the intestinal tract, as well as by bacterial enzymes in the intestine. The nuclear receptor farnesoid X receptor (FXR) and Gpbar1 (TGR5) are important set screws in this process. Bile acids have a vasodilatory effect, at least according to in vitro studies. The present review examines the question of the extent to which the increase in bile acids in plasma could be responsible for the hyperdynamic circulatory disturbance of liver cirrhosis and whether modulation of the bile acid pool, for example, via administration of ursodeoxycholic acid (UDCA) or via modulation of the dysbiosis present in liver cirrhosis could influence the hemodynamic disorder of liver cirrhosis. According to our analysis, the evidence for this is limited. Long-term studies on this question are lacking.

Liver Fibrosis-From Mechanisms of Injury to Modulation of Disease.

The Transregional Collaborative Research Center "Organ Fibrosis: From Mechanisms of Injury to Modulation of Disease" (referred to as SFB/TRR57) was funded for 13 years (2009-2021) by the German Research Council (DFG). This consortium was hosted by the Medical Schools of the RWTH Aachen University and Bonn University in Germany. The SFB/TRR57 implemented combined basic and clinical research to achieve detailed knowledge in three selected key questions: (i) What are the relevant mechanisms and signal pathways required for initiating organ fibrosis? (ii) Which immunological mechanisms and molecules contribute to organ fibrosis? and (iii) How can organ fibrosis be modulated, e.g., by interventional strategies including imaging and pharmacological approaches? In this review we will summarize the liver-related key findings of this consortium gained within the last 12 years on these three aspects of liver fibrogenesis. We will highlight the role of cell death and cell cycle pathways as well as nutritional and iron-related mechanisms for liver fibrosis initiation. Moreover, we will define and characterize the major immune cell compartments relevant for liver fibrogenesis, and finally point to potential signaling pathways and pharmacological targets that turned out to be suitable to develop novel approaches for improved therapy and diagnosis of liver fibrosis. In summary, this review will provide a comprehensive overview about the knowledge on liver fibrogenesis and its potential therapy gained by the SFB/TRR57 consortium within the last decade. The kidney-related research results obtained by the same consortium are highlighted in an article published back-to-back in Frontiers in Medicine.

Combination of phosphodiesterase-5-inhibitors and beta blockers improves experimental portal hypertension and erectile dysfunction.

BACKGROUND & AIMS: Phosphodiesterase-5 inhibitors (PDE-5-I) are used for treatment of erectile dysfunction (ED), which is common in patients with cirrhosis. They may improve portal hypertension (PH), but contradictory data on efficacy and side-effects have been reported. Non-selective beta blockers (NSBB) reduce portal pressure, but might aggravate ED. Thus, we evaluated the combination of PDE-5-I with NSBB and its impact on PH and ED in experimental cirrhosis. METHODS: ED was assessed in cirrhotic patients (n = 86) using standardized questionnaire. Experimental cirrhosis was induced by bile-duct-ligation or carbon-tetrachloride intoxication in rats. Corpus cavernosum pressure - a surrogate of ED -, as well as systemic and portal haemodynamics, were measured in vivo and in situ after acute administration of udenafil alone or in combination with propranolol. mRNA and protein levels of PDE-5 signalling were analysed using PCR and western Blot. RESULTS: ED in humans was related to severity of liver disease and to NSBB treatment. PDE-5 was mainly expressed in hepatic stellate cells and upregulated in human and experimental cirrhosis. Propranolol reduced corpus cavernosum pressure in cirrhotic rats and it was restored by udenafil. Even though udenafil treatment improved PH, it led to a reduction of mean arterial pressure. The combination of udenafil and propranolol reduced portal pressure and hepatic resistance without systemic side-effects. CONCLUSIONS: ED is common with advanced cirrhosis and concomitant NSBB treatment. The combination of PDE-5-I and NSBB improves ED and PH in experimental cirrhosis.

Short-Term Western Diet Aggravates Non-Alcoholic Fatty Liver Disease (NAFLD) With Portal Hypertension in TGR(mREN2)27 Rats.

Non-alcoholic fatty liver disease (NAFLD) is gaining in importance and is linked to obesity. Especially, the development of fibrosis and portal hypertension in NAFLD patients requires treatment. Transgenic TGR(mREN2)27 rats overexpressing mouse renin spontaneously develop NAFLD with portal hypertension but without obesity. This study investigated the additional role of obesity in this model on the development of portal hypertension and fibrosis. Obesity was induced in twelve-week old TGR(mREN2)27 rats after receiving Western diet (WD) for two or four weeks. Liver fibrosis was assessed using standard techniques. Hepatic expression of transforming growth factor-ß1 (TGF-ß1), collagen type Iα1, α-smooth muscle actin, and the macrophage markers Emr1, as well as the chemoattractant Ccl2, interleukin-1ß (IL1ß) and tumor necrosis factor-α (TNFα) were analyzed. Assessment of portal and systemic hemodynamics was performed using the colored microsphere technique. As expected, WD induced obesity and liver fibrosis as confirmed by Sirius Red and Oil Red O staining. The expression of the monocyte-macrophage markers, Emr1, Ccl2, IL1ß and TNFα were increased during feeding of WD, indicating infiltration of macrophages into the liver, even though this increase was statistically not significant for the EGF module-containing mucin-like receptor (Emr1) mRNA expression levels. Of note, portal pressure increased with the duration of WD compared to animals that received a normal chow. Besides obesity, WD feeding increased systemic vascular resistance reflecting systemic endothelial and splanchnic vascular dysfunction. We conclude that transgenic TGR(mREN2)27 rats are a suitable model to investigate NAFLD development with liver fibrosis and portal hypertension. Tendency towards elevated expression of Emr1 is associated with macrophage activity point to a significant role of macrophages in NAFLD pathogenesis, probably due to a shift of the renin-angiotensin system towards a higher activation of the classical pathway. The hepatic injury induced by WD in TGR(mREN2)27 rats is suitable to evaluate different stages of fibrosis and portal hypertension in NAFLD with obesity.

[Balthasar Neumann and His Disease]. / Balthasar Neumann und seine Krankheit.

On August 26 in 1753, Balthasar Neumann's wife wrote a letter to the Abbot of Neresheim describing her husband's disease one week after his death. This article outlines Neumann's medical history and builds connections towards the understanding of diseases in these times. As an example - and probably Neumann's ailment - the gastric cerarcinoma is discussed with special attention in this report.

TGR(mREN2)27 rats develop non-alcoholic fatty liver disease-associated portal hypertension responsive to modulations of Janus-kinase 2 and Mas receptor.

Prevalence of non-alcoholic fatty liver disease (NAFLD) is increasing. Resulting fibrosis and portal hypertension, as a possible secondary event, may necessitate treatment. Overexpression of mouse renin in the transgenic rat model, TGR(mREN2)27, leads to spontaneous development of NAFLD. Therefore, we used TGR(mREN2)27 rats as a model of NAFLD where we hypothesized increased susceptibility and investigated fibrosis and portal hypertension and associated pathways. 12-week old TGR(mREN2)27 rats received either cholestatic (BDL) or toxic injury (CCl4 inhalation). Portal and systemic hemodynamic assessments were performed using microsphere technique with and without injection of the Janus-Kinase 2 (JAK2) inhibitor AG490 or the non-peptidic Ang(1-7) agonist, AVE0991. The extent of liver fibrosis was assessed in TGR(mREN2)27 and wild-type rats using standard techniques. Protein and mRNA levels of profibrotic, renin-angiotensin system components were assessed in liver and primary hepatic stellate cells (HSC) and hepatocytes. TGR(mREN2)27 rats developed spontaneous, but mild fibrosis and portal hypertension due to the activation of the JAK2/Arhgef1/ROCK pathway. AG490 decreased migration of HSC and portal pressure in isolated liver perfusions and in vivo. Fibrosis or portal hypertension after cholestatic (BDL) or toxic injury (CCl4) was not aggravated in TGR(mREN2)27 rats, probably due to decreased mouse renin expression in hepatocytes. Interestingly, portal hypertension was even blunted in TGR(mREN2)27 rats (with or without additional injury) by AVE0991. TGR(mREN2)27 rats are a suitable model of spontaneous liver fibrosis and portal hypertension but not with increased susceptibility to liver damage. After additional injury, the animals can be used to evaluate novel therapeutic strategies targeting Mas.

Smaller-Diameter Covered Transjugular Intrahepatic Portosystemic Shunt Stents Are Associated With Increased Survival.

BACKGROUND & AIMS: We studied the effects of diameter of covered, self-expandable, nitinol stents on survival times of patients with a transjugular intrahepatic portosystemic shunt (TIPS). METHODS: We collected data from 185 patients (median age, 55 y; 30% female) who received a covered nitinol stent, from February 2006 through September 2010, using the online multicenter German TIPS registry. TIPS were given to 107 patients for refractory ascites and to 78 patients for variceal bleeding. Patients at risk of hepatic encephalopathy (owing to advanced age, prior episodes) or liver failure (bilirubin level, >3 mg/dL), and bleeding patients receiving variceal embolization at TIPS, received 8-mm stents (n = 53). The remaining patients received 10-mm stents (n = 132). Eighty-one of the 10-mm stents were underdilated using 8-mm dilation balloons. Clinical and biochemical data were collected after TIPS placement at 1 month, 3 months, 6 months, 9 months, 1 year, and thereafter every 3 to 6 months. Groups were compared using propensity score analysis. RESULTS: Patients who received 8-mm stents survived significantly longer (34 ± 26 mo) than patients who received 10-mm stents (18 ± 19 mo), regardless of whether they were fully dilated or underdilated. When we compared 10-mm stents with or without underdilation, we found that a significantly higher proportion of patients who received underdilated stents survived for 1 month after TIPS placement (95% vs 84%; P = .03), but not for 3 months (P = .10). In multivariate analysis, 1-year mortality correlated with full dilation of the stent to 10 mm (hazard ratio [HR], 2.0; 95% CI, 1.1-3.5) and with serum creatinine concentration at baseline (HR, 1.5; 95% CI, 1.0-1.7). Five-year mortality was associated with use of the 10-mm stents (HR, 1.8; 95% CI, 1.4-2.7) and baseline concentration of creatinine (HR, 1.3; 95% CI, 1.1-1.6). CONCLUSIONS: A smaller stent (nominal diameter of 8 mm, but not underdilation of a 10-mm stent) is associated with a prolonged survival compared with 10-mm stents, independent of liver-specific prognostic criteria.

Addressing Profiles of Systemic Inflammation Across the Different Clinical Phenotypes of Acutely Decompensated Cirrhosis.

Background: Patients with acutely decompensated cirrhosis (AD) may or may not develop acute-on-chronic liver failure (ACLF). ACLF is characterized by high-grade systemic inflammation, organ failures (OF) and high short-term mortality. Although patients with AD cirrhosis exhibit distinct clinical phenotypes at baseline, they have low short-term mortality, unless ACLF develops during follow-up. Because little is known about the association of profile of systemic inflammation with clinical phenotypes of patients with AD cirrhosis, we aimed to investigate a battery of markers of systemic inflammation in these patients. Methods: Upon hospital admission baseline plasma levels of 15 markers (cytokines, chemokines, and oxidized albumin) were measured in 40 healthy controls, 39 compensated cirrhosis, 342 AD cirrhosis, and 161 ACLF. According to EASL-CLIF criteria, AD cirrhosis was divided into three distinct clinical phenotypes (AD-1: Creatinine<1.5, no HE, no OF; AD-2: creatinine 1.5-2, and or HE grade I/II, no OF; AD-3: Creatinine<1.5, no HE, non-renal OF). Results: Most markers were slightly abnormal in compensated cirrhosis, but markedly increased in AD. Patients with ACLF exhibited the largest number of abnormal markers, indicating "full-blown" systemic inflammation (all markers). AD-patients exhibited distinct systemic inflammation profiles across three different clinical phenotypes. In each phenotype, activation of systemic inflammation was only partial (30% of the markers). Mortality related to each clinical AD-phenotype was significantly lower than mortality associated with ACLF (p < 0.0001 by gray test). Among AD-patients baseline systemic inflammation (especially IL-8, IL-6, IL-1ra, HNA2 independently associated) was more intense in those who had poor 28-day outcomes (ACLF, death) than those who did not experience these outcomes. Conclusions: Although AD-patients exhibit distinct profiles of systemic inflammation depending on their clinical phenotypes, all these patients have only partial activation of systemic inflammation. However, those with the most extended baseline systemic inflammation had the highest the risk of ACLF development and death.

Treatment of Oesophageal Varices in Liver Cirrhosis.

BACKGROUND: The development of cirrhosis with resultant portal hypertension can lead to oesophageal varices at a rate of 7% per annum. Bleeding from varices happens when the portal pressure is ≥12 mm Hg and can threaten life. SUMMARY: Eliminating the aetiology of cirrhosis is a pivotal step to prevent the formation of varices. In patients with established varices, primary prophylaxis with non-selective beta blockers (NSBB) may slow down the progression of varices and prevent the first variceal bleed. NSBB, similar to other agents such as renin/angiotensin blockers, statins, and rifaximin, may have the additional advantage of blunting inflammatory stimuli, which can contribute to the progression of varices. Variceal band ligation is an alternative for primary bleeding prophylaxis with excellent results. Any acute variceal bleed should be managed with band ligation after careful resuscitation. Early pre-emptive transjugular intrahepatic portosystemic shunt (TIPS) in decompensated cirrhotic patients is very effective in controlling the bleeding and improves survival. Secondary prophylaxis against further variceal bleeding using NSBB and band ligation is recommended in most other patients. TIPS may be considered in appropriate patients as a secondary prophylaxis against recurrent variceal bleed. Future research should be directed towards the prevention of varices and targeting inflammation to reduce cirrhotic complications. Key Messages: Treatment strategies depend on the stage the patient is at along the natural history of varices: NSBB or band ligation for primary prophylaxis; band ligation or early TIPS for acute bleed; and a combination of NSBB + band ligation or TIPS for secondary prophylaxis (Fig. 1).

Managing portal hypertension in patients with liver cirrhosis.

Portal hypertension is one cause and a part of a dynamic process triggered by chronic liver disease, mostly induced by alcohol or incorrect nutrition and less often by viral infections and autoimmune or genetic disease. Adequate staging - continuously modified by current knowledge - should guide the prevention and treatment of portal hypertension with defined endpoints. The main goals are interruption of etiology and prevention of complications followed, if necessary, by treatment of these. For the past few decades, shunts, mostly as intrahepatic stent bypass between portal and hepatic vein branches, have played an important role in the prevention of recurrent bleeding and ascites formation, although their impact on survival remains ambiguous. Systemic drugs, such as non-selective beta-blockers, statins, or antibiotics, reduce portal hypertension by decreasing intrahepatic resistance or portal tributary blood flow or by blunting inflammatory stimuli inside and outside the liver. Here, the interactions among the gut, liver, and brain are increasingly examined for new therapeutic options. There is no general panacea. The interruption of initiating factors is key. If not possible or if not possible in a timely manner, combined approaches should receive more attention before considering liver transplantation.
