Use of human albumin infusion in cirrhotic patients: a systematic review and meta-analysis of randomized controlled trials

Serum Albumin for Short-Term Poor Prognosis in Patients With Acute Pulmonary Embolism: A Clinical Study Based on a Database

The relationship between serum albumin (ALB) and short-term prognosis in patients with acute pulmonary embolism (APE) remains unclear. We investigated the predictive value of ALB for short-term prognosis in APE patients using our hospital pulmonary embolism (PE) database (384 patients consecutively collected). Logistic regression analysis and nomograms were applied to construct the predictive model, and validation was assessed. A total of 340 APE patients were included, with a 30-day all-cause mortality rate of 8.5%. The incidence of hypoalbuminemia was 15.9%. The odds ratio (OR) for short-term mortality in patients with high ALB was 0.89 (0.886, 95% CI: 0.812-0.967). Additionally, we created a nomogram for individualized mortality risk prediction. Receiver operating characteristic (ROC) curve analysis showed that the diagnostic area under the curve (AUC) of ALB was 0.758 (95% CI 0.683-0.833), and the best cut-off value was 33.85 g/L. Optimal simplified Pulmonary Embolism Severity Index (sPESI) (ALB combined sPESI) AUC was 0.835 (95% CI 0.775-0.896). Baseline hypoalbuminemia may be an independent prognostic indicator of short-term mortality in patients with APE.

Drainage of ascites in cirrhosis

For cirrhotic refractory ascites, diuretics combined with albumin and vasoactive drugs are the first-line choice for ascites management. However, their therapeutic effects are limited, and most refractory ascites do not respond to medication treatment, necessitating consideration of drainage or surgical interventions. Consequently, numerous drainage methods for cirrhotic ascites have emerged, including large-volume paracentesis, transjugular intrahepatic portosystemic shunt, peritoneovenous shunt, automated low-flow ascites pump, cell-free and concentrated ascites reinfusion therapy, and peritoneal catheter drainage. This review introduces the advantages and disadvantages of these methods in different aspects, as well as indications and contraindications for this disease.

Efficacy of albumin use in decompensated cirrhosis and real-world adoption in Australia

The current treatment approach to patients with liver cirrhosis relies on the individual management of complications. Consequently, there is an unmet need for an overall therapeutic strategy for primary and secondary prevention of complications. The clinical potential of long-term albumin infusions supported by recent clinical trials has expanded its indications and holds promise to transform the management and secondary prevention of cirrhosis-related complications. This renewed interest in albumin comes with inherent controversies, compounding challenges and pressing need for rigorous evaluation of its clinical potential to capitalize on its therapeutic breakthroughs. Australia is among a few countries worldwide to adopt outpatient human albumin infusion. Here, we summarize currently available evidence of the potential benefits of human albumin for the management of multiple liver cirrhosis-related complications and discuss key challenges for wide application of long-term albumin administration strategy in Australian clinical practice. Australian Gastroenterological week (AGW), organised by the Gastroenterological Society of Australia (GESA), was held between 9-11 September 2022. A panel of hepatologists, advanced liver nurses and one haematologist, were invited to a roundtable meeting to discuss the use of long-term albumin infusions for liver cirrhosis. management in Australia. In this review, we summarise the proceedings of this meeting in context of the current literature.

Durability and on-treatment predictors of recompensation in entecavir-treated patients with hepatitis B and decompensated cirrhosis

BACKGROUND & AIMS

Hepatic recompensation may be achieved in patients with decompensated cirrhosis due to chronic hepatitis B (CHB) upon effective suppression of viral replication by nucleos(t)ide analogues (NAs). However, the optimal timing and predictors of recompensation and the subsequent clinical course of patients with CHB with vs. without recompensation are not well-defined.

METHODS

This study was a retrospective extension of a multi-centre prospective cohort, focusing on patients with CHB and decompensated cirrhosis treated with entecavir. We followed patients beyond treatment week 120 until a second decompensation event or June 2023. We identified the optimal timing and predictors of recompensation by week 120, evaluated durability of recompensation in patients fulfilling recompensation criteria by week 120 and examined late recompensation in those who did not fulfil it by week 120.

RESULTS

At treatment week 24, serum albumin ≥34 g/L predicted recompensation by week 120. The Brec-PAS model offered good predictive ability for recompensation by week 120. Of the 283 patients who finished 120 weeks of therapy, 175 were followed beyond week 120 (median follow-up: 240 weeks). Among the 106 patients achieving recompensation by week 120, 92 (86.8%) maintained recompensation for another 120 (72-168) weeks. Among the 69 patients without recompensation by week 120, 40.6% attained late recompensation during the subsequent 120 (72-168) weeks. Additionally, hepatocellular carcinoma incidence was lower in the recompensated group (5.0% vs. 16.13%, p = 0.002).

CONCLUSIONS

A serum albumin ≥34 g/L at treatment week 24 predicted recompensation by week 120. Recompensation achieved by week 120 of NA treatment is maintained in >80% of patients in the long term. Some patients may achieve recompensation only after >120 weeks of NA treatment. The incidence of hepatocellular carcinoma was reduced but not completely abolished after recompensation.

IMPACT AND IMPLICATIONS

Our research provides a meaningful contribution to understanding the long-term prognosis of recompensation in patients with chronic hepatitis B and decompensated cirrhosis, as well as to evaluating the predictive value of serum albumin levels, offering a comprehensive view of clinical outcomes after recompensation. The significance of early biomarkers in guiding therapeutic decisions is highlighted, shedding light on the continued benefits and possible risks after recompensation. This enhances the capability for more precise prognostic evaluations and informed therapeutic strategies. For healthcare providers, these insights afford a detailed perspective on patient monitoring and intervention planning, underscoring the need for ongoing assessment past the initial recompensation phase.

European Society of Intensive Care Medicine clinical practice guideline on fluid therapy in adult critically ill patients. Part 1: the choice of resuscitation fluids

PURPOSE

This is the first of three parts of the clinical practice guideline from the European Society of Intensive Care Medicine (ESICM) on resuscitation fluids in adult critically ill patients. This part addresses fluid choice and the other two will separately address fluid amount and fluid removal.

METHODS

This guideline was formulated by an international panel of clinical experts and methodologists. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was applied to evaluate the certainty of evidence and to move from evidence to decision.

RESULTS

For volume expansion, the guideline provides conditional recommendations for using crystalloids rather than albumin in critically ill patients in general (moderate certainty of evidence), in patients with sepsis (moderate certainty of evidence), in patients with acute respiratory failure (very low certainty of evidence) and in patients in the perioperative period and patients at risk for bleeding (very low certainty of evidence). There is a conditional recommendation for using isotonic saline rather than albumin in patients with traumatic brain injury (very low certainty of evidence). There is a conditional recommendation for using albumin rather than crystalloids in patients with cirrhosis (very low certainty of evidence). The guideline provides conditional recommendations for using balanced crystalloids rather than isotonic saline in critically ill patients in general (low certainty of evidence), in patients with sepsis (low certainty of evidence) and in patients with kidney injury (very low certainty of evidence). There is a conditional recommendation for using isotonic saline rather than balanced crystalloids in patients with traumatic brain injury (very low certainty of evidence). There is a conditional recommendation for using isotonic crystalloids rather than small-volume hypertonic crystalloids in critically ill patients in general (very low certainty of evidence).

CONCLUSIONS

This guideline provides eleven recommendations to inform clinicians on resuscitation fluid choice in critically ill patients.

Review article: Recent advances in ascites and acute kidney injury management in cirrhosis

BACKGROUND

Better understanding of disease pathophysiology has led to advances in managing ascites and its associated complications including hepatorenal syndrome-acute kidney Injury (HRS-AKI), especially medicinal and interventional advances.

AIM

To review the latest changes in the management of ascites and HRS-AKI.

METHODS

A literature search was conducted in Pubmed, using the keywords cirrhosis, ascites, renal dysfunction, acute kidney injury, hepatorenal syndrome, beta-blockers, albumin, TIPS and vasoconstrictors, including only publications in English.

RESULTS

The medicinal advances include earlier treatment of clinically significant portal hypertension to delay the onset of ascites and the use of human albumin solution to attenuate systemic inflammation thus improving the haemodynamic changes associated with cirrhosis. Furthermore, new classes of drugs such as sodium glucose co-transporter 2 are being investigated for use in patients with cirrhosis and ascites. For HRS-AKI management, newer pharmacological agents such as vasopressin partial agonists and relaxin are being studied. Interventional advances include the refinement of TIPS technique and patient selection to improve outcomes in patients with refractory ascites. The development of the alfa pump system and the study of outcomes associated with the use of long-term palliative abdominal drain will also serve to improve the quality of life in patients with refractory ascites.

CONCLUSIONS

New treatment strategies emerged from better understanding of the pathophysiology of ascites and HRS-AKI have shown improved prognosis in these patients. The future will see many of these approaches confirmed in large multi-centre clinical trials with the aim to benefit the patients with ascites and HRS-AKI.

Management of liver disease and portal hypertension in cystic fibrosis: a review

INTRODUCTION

Cystic fibrosis (CF)-associated liver disease can significantly affect the quality of life and survival of people with CF. The hepatobiliary manifestations in CF are various, with focal/multilobular biliary cirrhosis more common in children and porto-sinusoidal vascular disease (PSVD) in young adults. Portal hypertensive complications, particularly bleeding from esophagogastric varices and hypersplenism are common, while liver failure is rarer and mainly linked to biliary disease.

AREAS COVERED

This review explores current therapeutic options for CF-associated liver disease, presenting ongoing studies and new insights into parthenogenesis for potential future therapies.

EXPERT OPINION

Monitoring for signs of portal hypertension is essential. Limited evidence supports ursodeoxycholic acid (UDCA) efficacy in halting CF liver disease progression. The effect of cystic fibrosis transmembrane conductance regulator (CFTR) modulators on liver outcomes lacks definitive data, since patients with CF-related liver disease were excluded from trials due to potential hepatotoxicity. A proposed approach involves using UDCA and modulators in early stages, along with anti-inflammatory agents, with further therapeutic strategies awaiting randomized trials. Prevention of portal hypertensive bleeding includes endoscopic sclerotherapy or ligation of esophageal varices. Nonselective beta-blockers may also prevent bleeding and could be cautiously implemented. Other non-etiological treatments require investigation.

Evolving portal hypertension through Baveno VII recommendations

The Baveno VII consensus workshop has provided several novel recommendations regarding the management of patients with clinically significant portal hypertension (CSPH). The expert panel summarized the existing data into simple clinical rules to aid clinicians in their clinical practice. The use of non-invasive tests (NITs), especially liver stiffness measurement (LSM), have gain an important role in daily practice. The use of LSM alone or in combination with platelet count can be used to rule-in and rule-out compensated advanced chronic liver disease (cACLD) and CSPH. Further decompensation events were defined as a prognostic stage associated with an even higher mortality than that associated with first decompensation. Moreover, the term hepatic recompensation was introduced in Baveno VII consensus implying a partial or complete regression of the functional and structural changes of cirrhosis after the removal of the underlying etiology. This review will summarize the reader main aspects of Baveno VII consensus regarding the use of NITs in cACLD, analyze further decompensation events, and evaluate recent recommendations for prophylaxis and management of liver decompensation events.

Pathophysiology of Hepatorenal Syndrome - Acute Kidney Injury

Hepatorenal syndrome is a complication of liver cirrhosis with ascites that results from the complex interplay of many pathogenetic mechanisms. Advanced cirrhosis is characterized by the development of hemodynamic changes of splanchnic and systemic arterial vasodilatation, with paradoxical renal vasoconstriction and renal hypoperfusion. Cirrhosis is also an inflammatory state. The inflammatory cascade is initiated by a portal hypertension-induced increased translocation of bacteria, bacterial products, and endotoxins from the gut to the splanchnic and then to the systemic circulation. The inflammation, whether sterile or related to infection, is responsible for renal microcirculatory dysfunction, microthrombi formation, renal tubular oxidative stress, and tubular damage. Of course, many of the bacterial products also have vasodilatory properties, potentially exaggerating the state of vasodilatation and worsening the hemodynamic instability in these patients. The presence of cardiac dysfunction, related to cirrhotic cardiomyopathy, with its associated systolic incompetence, can aggravate the mismatch between the circulatory capacitance and the circulation volume, worsening the extent of the effective arterial underfilling, with lower renal perfusion pressure, contributing to renal hypoperfusion and increasing the risk for development of acute kidney injury. The presence of tense ascites can exert an intra-abdominal compartmental syndrome effect on the renal circulation, causing renal congestion and hampering glomerular filtration. Other contributing factors to renal dysfunction include the tubular damaging effects of cholestasis and adrenal dysfunction. Future developments include the use of metabolomics to identify metabolic pathways that can lead to the development of renal dysfunction, with the potential of identifying biomarkers for early diagnosis of renal dysfunction and the development of treatment strategies.

Use of albumin infusion for cirrhosis-related complications: An international position statement

BACKGROUND & AIMS

Numerous studies have evaluated the role of human albumin (HA) in managing various liver cirrhosis-related complications. However, their conclusions remain partially controversial, probably because HA was evaluated in different settings, including indications, patient characteristics, and dosage and duration of therapy.

METHODS

Thirty-three investigators from 19 countries with expertise in the management of liver cirrhosis-related complications were invited to organise an International Special Interest Group. A three-round Delphi consensus process was conducted to complete the international position statement on the use of HA for treatment of liver cirrhosis-related complications.

RESULTS

Twelve clinically significant position statements were proposed. Short-term infusion of HA should be recommended for the management of hepatorenal syndrome, large volume paracentesis, and spontaneous bacterial peritonitis in liver cirrhosis. Its effects on the prevention or treatment of other liver cirrhosis-related complications should be further elucidated. Long-term HA administration can be considered in specific settings. Pulmonary oedema should be closely monitored as a potential adverse effect in cirrhotic patients receiving HA infusion.

CONCLUSIONS

Based on the currently available evidence, the international position statement suggests the potential benefits of HA for the management of multiple liver cirrhosis-related complications and summarises its safety profile. However, its optimal timing and infusion strategy remain to be further elucidated.

IMPACT AND IMPLICATIONS

Thirty-three investigators from 19 countries proposed 12 position statements on the use of human albumin (HA) infusion in liver cirrhosis-related complications. Based on current evidence, short-term HA infusion should be recommended for the management of HRS, LVP, and SBP; whereas, long-term HA administration can be considered in the setting where budget and logistical issues can be resolved. However, pulmonary oedema should be closely monitored in cirrhotic patients who receive HA infusion.

Meta-analysis: Efficacy and safety of albumin in the prevention and treatment of complications in patients with cirrhosis

INTRODUCTION

Albumin is used in multiple situations in patients with cirrhosis, but the evidence of its benefit is not always clear. The aim was to synthesise the evidence on the efficacy and safety of albumin compared to other treatments or no active intervention in cirrhotic patients.

MATERIALS AND METHODS

We conducted a systematic review including randomised controlled trials (RCTs) published in MEDLINE, EMBASE and CENTRAL up to May 2022. We assessed all-cause mortality, liver transplant, cirrhosis complications of any type and serious adverse events (SAEs). Second, AEs, hospital readmission, length of hospital stay, need for paracentesis and quality of life (QoL) were evaluated. Meta-analyses with Mantel-Haenszel method and random-effects model were performed.

RESULTS

Fifty studies (5118 participants) were included. Albumin was associated with a reduction in mortality in cirrhotic patients with spontaneous bacterial peritonitis (SBP) (RR 0.49, 95% CI 0.32-0.75; low certainty) and hepatic encephalopathy (HE) (RR 0.53, 95% CI 0.34-0.83; low certainty) when compared to no administration of albumin, but not in other scenarios. In general, no additional benefit of albumin was found in liver transplants, SAEs or cirrhosis complications (low/very low certainty). Long-term administration (>3 months) of albumin led to a reduction in cirrhosis complications (RR 0.75, 95% CI 0.57-0.97; low certainty), hospital readmissions, length of hospital stay, need for paracentesis and improvement of QoL.

CONCLUSION

Albumin may reduce mortality risk in cirrhotic patients with SBP or HE. No benefit was identified in reducing liver transplants or SAEs. Long-term administration may be associated with a lower risk of cirrhosis complications and need for paracentesis.
