Low-dose continuous terlipressin infusion is effective and safer than intravenous bolus injections in reducing portal pressure and control of acute variceal bleeding

Multisystem hemodynamic effects of terlipressin in cirrhosis: A scoping review

INTRODUCTION

Hepatorenal syndrome (HRS-AKI) is a serious complication of advanced liver disease. Pharmacologic options are limited in effectiveness, therefore liver transplantation is the definitive therapy. Early investigation into terlipressin as a first-line therapy for HRS-AKI has been promising but expected hemodynamic changes across organ systems in patients with cirrhosis have not been thoroughly examined.

METHODS

We conducted a scoping review of the literature including adult patients with cirrhosis who received terlipressin and hemodynamic parameters were recorded. Non-human studies, case reports, conference abstracts, and review articles were excluded. Searches were performed up to December 2024 in the following databases: MEDLINE, Embase, Cochrane Library, Scopus, Web of Science, and CINAHL.

RESULTS

Of 2022 studies retrieved, 56 studies met inclusion criteria. Heart rate, mean arterial pressure, and cardiac output were the most reported parameters. Pulmonary arterial pressure and wedge pressure were the next most common. Systemic vascular resistance, hepatic and renal measures such as resistive indices and portal pressure gradients had fewer studies. Studies reported decreased heart rate, increased mean arterial pressure, decreased cardiac output/index, and increased systemic vascular resistance. Other hemodynamic outcomes were more varied across studies.

CONCLUSIONS

Terlipressin exerts a variety of hemodynamic effects across organ systems and vascular beds. More studies are required to understand if any hemodynamic parameters might predict terlipressin response or adverse events.

Effectiveness and safety evaluation of terlipressin in the treatment of intestinal paralysis in end-stage liver disease

BACKGROUND AND AIMS

Intestinal paralysis is a common complication in end-stage liver disease (ESLD), our aim is to assess the effectiveness and safety of low-dose terlipressin for treating intestinal paralysis in ESLD.

METHODS

The study was divided into two phases, in the exploratory phase, we retrospectively analyzed the clinical data of patients with intestinal paralysis treated with low-dose terlipressin and explored its efficacy. In the clinical research phase, we designed a prospective cohort study, patients with intestinal paralysis were categorized into terlipressin treatment group (low-dose terlipressin was added to the conventional treatment) and conventional treatment group according to their wishes. The remission of intestinal paralysis, time to symptom remission, and differences in adverse reactions were compared between the two groups.

RESULTS

In the exploratory phase, 26 patients were exposed to low-dose terlipressin, 12 were cured, 11 were moderately effective, and 3 were ineffective. The mean time to abdominal bloating remission was 2 days, and the time to anal flatus and feces passage was 1 day. In the clinical research phase, a total of 131 patients were included at baseline, with the exception of one patient who discontinued medication due to severe vomiting, resulting in a final total of 130 patients included in the analysis. The mean time to abdominal pain and bloating remission in the terlipressin treatment group (32/130) was demonstrably shorter compared to the conventional treatment group (98/130) (P < 0.001), the mean time to anal flatus and feces passage was also shorter (P < 0.001), and the remission rate was higher (P < 0.05). The incidence of adverse events was similar.

CONCLUSIONS

Low-dose terlipressin treatment could considerably increase intestinal paralysis remission in ESLD patients with intestinal paralysis, and have good safety.

Efficacy and safety of terlipressin infusion during liver surgery: a meta-analysis

Although numerous studies have investigated terlipressin (TP) administration in liver surgery to mitigate bleeding, its efficacy remains controversial. This meta-analysis evaluates the effects of TP on estimated blood loss (EBL), blood transfusion requirements, and patient outcomes. We systematically searched PubMed, EMBASE, Cochrane Library, and Web of Science (WOS) for studies on perioperative TP use in liver surgery from their inception through February 2024. Only English-language publications were included. Primary outcomes included EBL and allogeneic blood transfusion volume. Twelve studies involving 988 eligible subjects were included. No significant differences were observed in EBL (weighted mean difference [WMD] =  - 99.09; 95% confidence interval [CI], - 318.41 to 120.24; P = 0.38), red blood cell (RBC) transfusion volume (standardized mean difference [SMD] =  - 0.10; 95% CI =  - 0.74 to 0.54; P = 0.76), or fresh frozen plasma (FFP) transfusion volume (SMD = 0.07; 95% CI =  - 0.24 to 0.37; P = 0.67). Subgroup analysis demonstrated that continuous TP infusion significantly reduced intraoperative EBL (WMD =  - 336.22; 95% CI =  - 562.13 to - 110.31; P = 0.004). TP infusion does not reduce intraoperative EBL or allogeneic blood transfusion requirements in liver surgery. However, continuous TP infusion may lower EBL.PROSPERO registration number: CRD42023450333.

Hemodynamic profile of terlipressin and octreotide in patients with cirrhosis and portal hypertension: a randomized, single-blind clinical trial

Background & Aims

Continuous infusion of terlipressin may result in a more sustained reduction in portal pressure with fewer adverse effects than administered as a bolus. This study aimed to compare the hepatic and cardiopulmonary hemodynamic effects and safety profiles of bolus vs. terlipressin continuous infusion.

Methods

This is a single-center, single-blinded, double-dummy, parallel-group, clinical trial in which 38 patients with cirrhosis and portal hypertension were randomized to receive the following: 1 mg bolus of terlipressin + continuous infusion of placebo (TERLBOL, n = 12), a bolus of placebo + continuous infusion of terlipressin (2 or 4 mg/day if <10% reduction in hepatic venous pressure gradient [HVPG] at 30 min of infusion) (TERLINF, n = 14), or a bolus of octreotide (50 μg) + continuous infusion of octreotide (50 μg/h) (OCTR, n = 12) as an additional control group. HVPG, cardiopulmonary pressures, and cardiac output were measured at baseline and after 30, 60, and 120 min.

Results

Sixty-eight percent of patients were male, with a median age of 59 years. There were no significant differences in baseline characteristics. In the TERLBOL group, there was a nonsignificant reduction in HVPG (at 120 min, -4.9%; p = 0.14). However, cardiopulmonary and mean arterial pressures significantly increased, whereas cardiac output and heart rate significantly decreased. In the TERLINF group, there were nonsignificant changes in cardiopulmonary hemodynamics or HVPG (NS) despite doubling the infusion dose after 30 min in 13/14 patients. In the OCTR group, there was a nonsignificant reduction in HVPG (at 120 min, -4.9%; p = 0.08), and pulmonary capillary pressure significantly decreased. All treatments were well tolerated, and no adverse events were observed.

Conclusions

There were nonsignificant reductions in HVPG with the three therapeutic strategies. Further investigations are warranted to determine the optimal dosing strategy for continuous infusion of terlipressin in patients with cirrhosis and portal hypertension.

Impact and implications

The results of our study do not show a significant reduction in portal pressure, at least in the first 2 h after the selected dose. Although the study was not performed in the setting of acute variceal bleeding and terlipressin was used as a standard therapy, these results do not support the treatment strategy of terlipressin infusion alone at the doses studied for the management of acute variceal bleeding, where a quick reduction in portal pressure is thought to play a major role controlling variceal bleeding. It is important to highlight that the continuously infused terlipressin regimen is better tolerated and appears to have a better cardiopulmonary safety profile. Other treatment strategies of continuous terlipressin infusion, such as initial bolus administration or higher infusion doses, should be evaluated to support its use in managing variceal bleeding.

The current applications and future directions of terlipressin

Terlipressin is a vasopressin analog with potent splanchnic vasoconstrictor properties. It has an established role in managing portal hypertensive bleeding and hepatorenal syndrome-acute kidney injury, with a growing body of evidence demonstrating improved safety and efficacy with continuous infusion-based administration compared to bolus dosing. We discuss previously reported adverse effects of terlipressin and evidence-based strategies to maximize the safety of administration. We also review the literature surrounding emerging indications for terlipressin in decompensated cirrhosis, particularly in the management of refractory ascites. Furthermore, we present data on novel ambulatory programs utilizing long-term continuous terlipressin infusion as bridging therapy for liver transplant candidates with recurrent hepatorenal syndrome-acute kidney injury, diuretic-refractory ascites, or hydrothorax.

Effect of Continuous Infusion Therapy With Low-dose Terlipressin Combined With Norepinephrine on Hemodynamics, Inflammatory Markers, and Prognosis in Patients With Severe Septic Shock

OBJECTIVE

The present study investigated the impact of continuous infusion therapy with low-dose terlipressin (TP) combined with norepinephrine on hemodynamics, inflammatory markers, and prognosis in patients with severe septic shock.

MATERIALS AND METHODS

Seventy-four patients with severe septic shock were randomly assigned to either a control group (n = 37) or an observation group (n = 37). Patients in the control group received norepinephrine alone, while those in the observation group received a continuous infusion of low-dose TP in addition to norepinephrine. To assess the effect of treatment, a set of clinical parameters was evaluated in both groups before and after treatment. These parameters included hemodynamic indicators (heart rate [HR], mean arterial pressure [MAP], central venous pressure [CVP], cardiac index [CI], and systemic vascular resistance index [SVRI]), levels of serum inflammatory markers (interleukin-8 [IL-8], tumor necrosis factor-α [TNF-α], and hypersensitivity C-reactive protein [hs-CRP]), renal function indicators (blood urea nitrogen [BUN], serum creatinine [SCr], and cystatin C [Cys-C]), serum procalcitonin (PCT), and lactate, as well as lactate clearance rate (LCR). Additionally, the acute physiology and chronic health evaluation II (APACHE II) score, 28-day mortality rate, multiple organ dysfunction syndrome (MODS) incidence rate, and adverse reaction incidence were also determined.

RESULTS

Compared to baseline values, MAP, CVP, CI, SVRI, and LCR increased in both groups after treatment, while HR, levels of IL-8, TNF-α, hs-CRP, BUN, SCr, PCT, and lactate all decreased. Additionally, APACHE II scores also decreased. Furthermore, the observation group exhibited higher MAP, CVP, CI, SVRI, and LCR, along with lower HR, levels of IL-8, TNF-α, hs-CRP, BUN, SCr, PCT, and lactate than the control group after treatment. The observation group also had lower APACHE II score, 28-day mortality rate, MODS incidence rate, and adverse reaction incidence than the control group after treatment (P < .05).

CONCLUSION

Continuous infusion therapy with low-dose TP combined with norepinephrine was effective in treating patients with severe septic shock, improving hemodynamic parameters, reducing the levels of inflammatory markers, promoting renal function recovery, and reducing the mortality rate.

Comprehensive approach to esophageal variceal bleeding: From prevention to treatment

Esophageal variceal bleeding is a severe complication often associated with portal hypertension, commonly due to liver cirrhosis. Prevention and treatment of this condition are critical for patient outcomes. Preventive strategies focus on reducing portal hypertension to prevent varices from developing or enlarging. Primary prophylaxis involves the use of non-selective beta-blockers, such as propranolol or nadolol, which lower portal pressure by decreasing cardiac output and thereby reducing blood flow to the varices. Endoscopic variceal ligation (EVL) may also be employed as primary prophylaxis to prevent initial bleeding episodes. Once bleeding occurs, immediate treatment is essential. Initial management includes hemodynamic stabilization followed by pharmacological therapy with vasoactive drugs such as octreotide or terlipressin to control bleeding. Endoscopic intervention is the cornerstone of treatment, with techniques such as EVL or sclerotherapy applied to directly manage the bleeding varices. In cases where bleeding is refractory to endoscopic treatment, transjugular intrahepatic portosystemic shunt may be considered to effectively reduce portal pressure. Long-term management after an acute bleeding episode involves secondary prophylaxis using beta-blockers and repeated EVL sessions to prevent rebleeding, complemented by monitoring and managing liver function to address the underlying disease. In light of new scientific evidence, including the findings of the study by Peng et al, this editorial aims to review available strategies for the prevention and treatment of esophageal varices.

Bleeding Complications of Portal Hypertension

In portal hypertension, acute variceal bleed is the cause of 2/3rd of all upper gastrointestinal bleeding episodes. It is a life-threatening emergency in patients with cirrhosis. Nonselective beta-blockers by decreasing the hepatic venous pressure gradient are the mainstay of medical therapy for the prevention of variceal bleeding and rebleeding. Evaluation of the severity of bleed, hemodynamic resuscitation, prophylactic antibiotic, and intravenous splanchnic vasoconstrictors should precede the endoscopy procedure. Endoscopic band ligation is the recommended endotherapy. Rescue transjugular intrahepatic port-systemic shunt (TIPS) is recommended for variceal bleed refractory to endotherapy. In patients with a high risk of failure of combined pharmacologic and endoscopic therapy, pre-emptive TIPS may improve the outcome. For gastric varices, "Sarin classification" is universally applied as it is simple and has therapeutic implication. For IGV1 and GOV2, injection cyanoacrylate glue is considered the endotherapy of choice. Endoscopic ultrasound is a useful modality in the management of gastric varices.

Management of hepatorenal syndrome and treatment-related adverse events

Hepatorenal Syndrome is a critical complication of liver failure, mainly in cirrhotic patients and rarely in patients with acute liver disease. It is a complex spectrum of conditions that leads to renal dysfunction in the liver cirrhosis population; the pathophysiology is characterized by a specific triad: circulatory dysfunction, nitric oxide (NO) dysfunction and systemic inflammation but a specific kidney damage has never been demonstrated, in a clinicopathological study, kidney biopsies of patients with cirrhosis showed a wide spectrum of kidney damage. In addition, the absence of significant hematuria or proteinuria does not exclude renal damage. It is estimated that 40% of cirrhotic patients will develop hepatorenal syndrome with in-hospital mortality of about one-third of these patients. The burden of the problem is dramatic considering the worldwide prevalence of more than 10 million decompensated cirrhotic patients, and the age-standardized prevalence rate of decompensated cirrhosis has gone through a significant rise between 1990 and 2017. Given the syndrome's poor prognosis, the clinician must know how to manage early treatment and any complications. The widespread adoption of albumin and vasopressors has increased Hepatorenal syndrome-acute kidney injury reversal and may increase overall survival, as previously shown. Further research is needed to define whether the subclassification of patients may allow to find a personalized strategy to treat Hepatorenal Syndrome and to define the role of new molecules and extracorporeal treatment may allow better outcomes with a reduction in treatment-related adverse effects. This review aims to examine both pharmacological and non-pharmacological treatment of hepatorenal syndrome, with a particular focus on managing adverse events caused by treatment.

Efficacy and safety of terlipressin infusion during liver surgery: a protocol for systematic review and meta-analysis

INTRODUCTION

Liver disease causes 2 million deaths annually, accounting for 4% of all deaths worldwide. Liver surgery is one of the effective therapeutic options. Bleeding is a major complication during liver surgery. Perioperative bleeding and allogeneic blood transfusion may deteriorate the prognosis. Terlipressin (TP), a synthetic analogue of the antidiuretic hormone, may reduceblood loss during abdominal surgery. Several clinical centres have attempted to use TP during liver surgery, but the evidence for its effectiveness in reducing blood loss and the need for allogeneic blood transfusion, as well as its safety during the perioperative period, remains unclear. The aim of this systematic review and meta-analysis is to evaluate the efficacy and safety of TP in reducing blood loss and allogeneic blood transfusion needs during liver surgery.

METHODS AND ANALYSIS

We will search PubMed, EMBASE, the Cochrane Library and Web of Science for studies on perioperative use of TP during liver surgery from inception to July 2023. We will limit the language to English, and two reviewers will independently screen and select articles. The primary study outcomes are estimated blood loss and the need for allogeneic blood transfusion. Secondary outcomes include operating time, intensive care unit stay, length of stay, intraoperative urine output, acute kidney injury rate, postoperative complications, hepatic and renal function during follow-up, and TP-related adverse effects. We will include studies that met the following criteria: (1) randomised controlled trials (RCTs), cohort studies or case-control studies; (2) the publication time was till July 2023; (3) adult patients (≥18 years old) undergoing elective liver surgery; (4) comparison of TP with other treatments and (5) the study includes at least one outcome. We will exclude animal studies, case reports, case series, non-original articles, reviews, paediatric articles, non-controlled trials, unpublished articles, non-English articles and other studies that are duplicates. We will use Review Manager V.5.3 software for meta-analysis and perform stratification analysis for the study quality of RCTs based on the Jadad score. For cohort or case-control studies, the study quality will be analysed based on Newcastle-Ottawa Scale scores. Grading of Recommendations, Assessment, Development and Evaluation will be used to assess confidence in the cumulative evidence. For primary outcomes, we will conduct subgroup analyses based on meta-regression. We will also perform leave-one-out sensitivity analyses to evaluate the effect of each individual study on the combined results by removing the individual studies one by one for outcomes with significant heterogeneity. The protocol follows the Cochrane Handbook for Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols guidelines.

ETHICS AND DISSEMINATION

This study is a secondary analysis of existing data; therefore, it does not require ethical approval. We will disseminate the results through peer-reviewed publications.

AGA Clinical Practice Update on the Use of Vasoactive Drugs and Intravenous Albumin in Cirrhosis: Expert Review

DESCRIPTION

Cirrhosis is a major cause of morbidity and mortality in the United States and worldwide. It consists of compensated, decompensated, and further decompensated stages; median survival is more than 15 years, 2 years, and 9 months for each stage, respectively. With each stage, there is progressive worsening of portal hypertension and the vasodilatory-hyperdynamic circulatory state, resulting in a progressive decrease in effective arterial blood volume and renal perfusion. Vasoconstrictors reduce portal pressure via splanchnic vasoconstriction and are used in the management of variceal hemorrhage. Intravenous (IV) albumin increases effective arterial blood volume and is used in the prevention of acute kidney injury (AKI) and death after large-volume paracentesis and in patients with spontaneous bacterial peritonitis (SBP). The combination of vasoconstrictors and albumin is used in the reversal of hepatorenal syndrome (HRS-AKI), the most lethal complication of cirrhosis. Because a potent vasoconstrictor, terlipressin, was recently approved by the US Food and Drug Administration, and because recent trials have explored use of IV albumin in other settings, it was considered that a best practice update would be relevant regarding the use of vasoactive drugs and IV albumin in the following 3 specific scenarios: variceal hemorrhage, ascites and SBP, and HRS.

METHODS

This expert review was commissioned and approved by the American Gastroenterological Association (AGA) Institute Clinical Practice Updates Committee and the AGA Governing Board to provide timely guidance on a topic of high clinical importance to the AGA membership. It underwent internal peer review through standard procedures of Gastroenterology. These Best Practice Advice statements were drawn from a review of the published literature and from expert opinion. Some of the statements are unchanged from published guidelines because of lack of new evidence in the literature. Because systematic reviews were not performed, these Best Practice Advice statements do not carry formal ratings regarding the quality and evidence or strength of the presented considerations. Best Practice Advice Statements BEST PRACTICE ADVICE 1: Vasoactive drugs should be initiated as soon as the diagnosis of variceal hemorrhage is suspected or confirmed, preferably before diagnostic and/or therapeutic endoscopy. BEST PRACTICE ADVICE 2: After initial endoscopic hemostasis, vasoactive drugs should be continued for 2-5 days to prevent early rebleeding. BEST PRACTICE ADVICE 3: Octreotide is the vasoactive drug of choice in the management of variceal hemorrhage based on its safety profile. BEST PRACTICE ADVICE 4: IV albumin should be administered at the time of large-volume (>5 L) paracentesis. BEST PRACTICE ADVICE 5: IV albumin may be considered in patients with SBP. BEST PRACTICE ADVICE 6: Albumin should not be used in patients (hospitalized or not) with cirrhosis and uncomplicated ascites. BEST PRACTICE ADVICE 7: Vasoconstrictors should not be used in the management of uncomplicated ascites, after large-volume paracentesis or in patients with SBP. BEST PRACTICE ADVICE 8: IV albumin is the volume expander of choice in hospitalized patients with cirrhosis and ascites presenting with AKI. BEST PRACTICE ADVICE 9: Vasoactive drugs (eg, terlipressin, norepinephrine, and combination of octreotide and midodrine) should be used in the treatment of HRS-AKI, but not in other forms of AKI in cirrhosis. BEST PRACTICE ADVICE 10: Terlipressin is the vasoactive drug of choice in the treatment of HRS-AKI and use of concurrent albumin can be considered when accounting for patient's volume status. BEST PRACTICE ADVICE 11: Terlipressin treatment does not require intensive care unit monitoring and can be administered intravenously through a peripheral line. BEST PRACTICE ADVICE 12: Terlipressin use is contraindicated in patients with hypoxemia and in patients with ongoing coronary, peripheral, or mesenteric ischemia, and should be used with caution in patients with acute-on-chronic liver failure grade 3. The benefits may not outweigh the risks in patients with serum creatinine >5 mg/dL and in patients listed for transplantation with a Model for End-stage Liver Disease ≥35.

Continuous vs. intermittent terlipressin infusion for portal hypertension: a systematic review and meta-analysis

Background

Portal hypertension, a major complication of chronic liver disease, often leads to life-threatening variceal bleeding, managed effectively with vasoactive drugs like terlipressin. However, the most optimal method of terlipressin administration, continuous versus intermittent infusion, remains a subject of debate, necessitating this systematic review and meta-analysis for evidence-based decision-making in managing this critical condition.

Methods

This systematic review and meta-analysis adhered to the PRISMA standards and explored multiple databases until 6 April 2023, such as MEDLINE through PubMed, Scopus, Web of Science, and CENTRAL. Independent reviewers selected randomized controlled trials (RCTs) that met specific inclusion criteria. After assessing study quality and extracting necessary data, statistical analysis was performed using Review Manager (RevMan), with results presented as risk ratios (RR) or mean differences.

Results

Five RCTs (n=395 patients) were included. The continuous terlipressin group had a significantly lower risk of rebleeding (RR=0.43, P=0.0004) and treatment failure (RR=0.22, P=0.02) and fewer total adverse effects (RR=0.52, P<0.00001) compared to the intermittent group. However, there were no significant differences between the two groups in mean arterial pressure (P=0.26), length of hospital stays (P=0.78), and mortality rates (P=0.65).

Conclusion

This study provides robust evidence suggesting that continuous terlipressin infusion may be superior to intermittent infusions in reducing the risk of rebleeding, treatment failure, and adverse effects in patients with portal hypertension. However, further large-scale, high-quality RCTs are required to confirm these findings and to investigate the potential benefits of continuous terlipressin infusion on mortality and hospital stays.

Effect of different infusion approaches on safety and efficacy of terlipressin: Current controversies

Terlipressin, a synthetic analog of vasopressin, has been widely used to treat acute variceal bleeding, hepatorenal syndrome, and other complications of cirrhosis. However, among different infusion approaches of terlipressin, its safety and efficacy are also heterogeneous. Previous studies have demonstrated that continuous infusion of terlipressin is more effective with a lower incidence of adverse events than intermittent intravenous infusion. This paper aims to review the relevant literature and summarize the data regarding the safety and effectiveness of different infusion approaches of terlipressin to guide clinical practice.

Terlipressin in the management of liver disease

INTRODUCTION

Terlipressin is a synthetic vasopressin analog which has been recently approved in the United States by the Food and Drug Administration for the treatment of hepatorenal syndrome. Terlipressin stimulates vasopressin receptors located on the smooth muscle vasculature of the splanchnic circulation and renal tubules which results in splanchnic vasoconstriction with improved renal perfusion and antidiuretic activity, respectively.

AREAS COVERED

In this review, we discuss available data regarding the FDA approved use of terlipressin, safety, and tolerability, as well as highlight alternative uses in chronic liver disease currently still under investigation.

EXPERT OPINION

Terlipressin is more efficacious compared to other vasoactive agents including midodrine octreotide and norepinephrine in reversal of hepatorenal syndrome and improves short-term survival. Other potential applications of terlipressin's vasoconstrictor actions reported in the literature include management of variceal hemorrhage and other complications of portal hypertension.

Advances in the diagnosis and management of hepatorenal syndrome: insights into HRS-AKI and liver transplantation

In hepatorenal syndrome-acute kidney injury (HRS-AKI), accurate and early diagnosis is crucial. HRS is a severe condition seen in advanced cirrhosis, requiring prompt recognition and proper management to enhance patient outcomes. Diagnosis of HRS-AKI relies on serum creatinine elevations, similar to other AKI cases in cirrhosis. However, distinguishing HRS-AKI from other renal impairments in these patients can be challenging. Biomarkers and clinical criteria aid in diagnosis and guide treatment. The management of HRS-AKI initially involves improving the haemodynamic profile using albumin and vasoconstrictors like terlipressin, a synthetic vasopressin analogue. Despite some reports linking terlipressin to increased adverse events compared with norepinephrine, it remains the preferred choice in HRS-AKI and acute-on-chronic liver failure due to its faster, stronger response and improved survival. Additional therapies like midodrine (alpha-1 adrenergic agonist), octreotide (somatostatin analogue) and transjugular intrahepatic portosystemic shunt are proposed as adjuvant treatments for HRS-AKI, aiming to improve vasoconstriction and renal blood flow. However, these adjunctive therapies cannot replace the definitive treatment for HRS-AKI-liver transplantation (LT). In cases unresponsive to medical management, LT is the only option to restore liver function and improve renal outcomes. Current evidence favours combined liver and kidney transplantation (CLKT) in certain situations. This review aims to evaluate the present evidence and recommendations on AKI in patients with cirrhosis, the pathophysiology of HRS-AKI, different treatments and indications for LT and CLKT. Understanding the complexities of managing HRS-AKI is crucial for optimising patient care and achieving better outcomes in this challenging clinical setting.

Austrian consensus on the diagnosis and management of portal hypertension in advanced chronic liver disease (Billroth IV)

The Billroth IV consensus was developed during a consensus meeting of the Austrian Society of Gastroenterology and Hepatology (ÖGGH) and the Austrian Society of Interventional Radiology (ÖGIR) held on the 26th of November 2022 in Vienna.Based on international recommendations and considering recent landmark studies, the Billroth IV consensus provides guidance regarding the diagnosis and management of portal hypertension in advanced chronic liver disease.
