Abstract
Hepatorenal syndrome (HRS) is a feared complication in patients with advanced cirrhosis and is associated with significant morbidity and mortality. While recognized as a distinct physiologic condition for well over one hundred years, a lack of objective diagnostic tests has made the diagnosis one of exclusion. Since 1979, multiple sets of diagnostic criteria have been proposed. Though varying in detail, the principal intent of these criteria is to identify patients with severe, functional acute kidney injury that is unresponsive to volume resuscitation and exclude those with structural injury. However, accurate differential diagnosis remains challenging. Recently, multiple urinary biomarkers of kidney injury, including neutrophil gelatinase-associated lipocalin, have been studied as a means of objectively phenotyping etiologies of acute kidney injury in patients with cirrhosis. Along with markers reflecting tubular functional integrity, including the fractional excretion of sodium, injury markers will likely be incorporated into future diagnostic criteria. Making an accurate diagnosis is critical, as therapeutic options exist for HRS but must be given in a timely manner and only to those patients likely to benefit. Terlipressin, an analog of vasopressin, is the first line of therapy for HRS in much of the world and has recently been approved for use in the United States. Significant questions remain regarding the optimal dosing strategy, metrics for titration, and the potential role of point-of-care ultrasound to help guide concurrent albumin administration.

Abstract
Hepatorenal syndrome (HRS) is a rare and highly morbid form of kidney injury unique to patients with decompensated cirrhosis. HRS is a physiologic consequence of portal hypertension, leading to a functional kidney injury that can be reversed by restoring effective circulating volume and renal perfusion. While liver transplantation is the only definitive "cure" for HRS, medical management with vasoconstrictors and i.v. albumin is a cornerstone of supportive care. Terlipressin, a V1a receptor agonist that acts on the splanchnic circulation, has been used for many years outside the United States for the treatment of HRS. However, its recent Food and Drug Administration approval has generated new interest in this population, as a new base of prescribers now work to incorporate the drug into clinical practice. In this article, we review HRS pathophysiology and diagnostic criteria, the clinical use of terlipressin and alternative therapies, and identify areas of future research in the space of HRS and kidney injury in cirrhosis.

Abstract
BACKGROUND During the perioperative period of living donor liver transplantation, anesthesiologists and intensivists may encounter patients in receipt of small grafts that puts them at risk of developing small for size syndrome (SFSS). METHODS A scientific committee (106 members from 21 countries) performed an extensive literature review on aspects of SFSS with proposed recommendations. Recommendations underwent a blinded review by an independent expert panel and discussion/voting on the recommendations occurred at a consensus conference organized by the International Liver Transplantation Society, International Living Donor Liver Transplantation Group, and Liver Transplantation Society of India. RESULTS It was determined that centers with experience in living donor liver transplantation should utilize potential small for size grafts. Higher risk recipients with sarcopenia, cardiopulmonary, and renal dysfunction should receive small for size grafts with caution. In the intraoperative phase, a restrictive fluid strategy should be considered along with routine use of cardiac output monitoring, as well as use of pharmacologic portal flow modulation when appropriate. Postoperatively, these patients can be considered for enhanced recovery and should receive proactive monitoring for SFSS, nutrition optimization, infection prevention, and consideration for early renal replacement therapy for avoidance of graft congestion. CONCLUSIONS Our recommendations provide a framework for the optimal anesthetic and critical care management in the perioperative period for patients with grafts that put them at risk of developing SFSS. There is a significant limitation in the level of evidence for most recommendations. This statement aims to provide guidance for future research in the perioperative management of SFSS.

Abstract
Cirrhosis is characterised by a prolonged asymptomatic period in which the inflammation persists, increasing as the disease progresses. Characteristic of this is the increase in pro-inflammatory cytokines and pro-oxidant molecules which are determining factors in the development of multiple organ dysfunction. In the early development of cirrhosis, splanchnic arterial vasodilation, activation of vasoconstrictor systems (renin-angiotensin-aldosterone) and the sympathetic nervous system (noradrenaline) bring about bacterial translocation and systemic dissemination via portal circulation of bacterial products, and molecular patterns associated with damage, which exacerbate the systemic inflammation present in the patient with cirrhosis. Albumin is a molecule that undergoes structural and functional changes as liver damage progresses, affecting its antioxidant, immunomodulatory, oncotic and endothelial stabilising properties. Our knowledge of the properties of albumin reveals a molecule with multiple treatment options in patients with cirrhosis, from the compensated then decompensated phases to multiple organ dysfunction. Its recognised uses in spontaneous bacterial peritonitis, post-paracentesis circulatory dysfunction, acute kidney injury and hepatorenal syndrome are fully validated, and a treatment option has opened up in decompensated cirrhosis and in acute-on-chronic liver disease.

Abstract
The occurrence of acute kidney injury (AKI) in patients with end-stage liver disease constitutes one of the most challenging clinical scenarios in in-hospital and critical care medicine. Hepatorenal syndrome type 1 (HRS-1), which is a specific type of AKI that occurs in the context of advanced cirrhosis and portal hypertension, is associated with particularly high mortality. The pathogenesis of HRS-1 is largely viewed as a functional derangement that ultimately affects renal vasculature tone. However, new insights suggest that non-haemodynamic tubulo-toxic factors, such as endotoxins and bile acids, might mediate parenchymal renal injury in patients with cirrhosis, suggesting that concurrent mechanisms, including those traditionally associated with HRS-1 and non-traditional factors, might contribute to the development of AKI in patients with cirrhosis. Moreover, histological evidence of morphological abnormalities in the kidneys of patients with cirrhosis and renal dysfunction has prompted the functional nature of HRS-1 to be re-examined. From a clinical perspective, a diagnosis of HRS-1 guides utilization of vasoconstrictive therapy and decisions regarding renal replacement therapy. Patients with cirrhosis are at risk of AKI owing to a wide range of factors. However, the tools currently available to ascertain the diagnosis of HRS-1 and guide therapy are suboptimal. Short of liver transplantation, goal-directed haemodynamically targeted pharmacotherapy remains the cornerstone of treatment for this condition; improved understanding of the underlying pathogenic mechanisms might lead to better clinical outcomes. Here, we examine our current understanding of the pathophysiology of HRS-1 and existing challenges in its diagnosis and treatment.

Abstract
Objective To evaluate the effectiveness of noradrenaline for the treatment of hepatorenal syndrome (HRS). Background HRS represents the development of renal failure in cirrhotic patients. The standard treatment for HRS is terlipressin, which, as opposed to noradrenaline, is more expensive and less accessible in most tertiary care centers. Patients and methods Thirty consecutive patients with HRS type 1 received noradrenaline (1–4.0 mg/hour) and albumin for 14 days. The parameters recorded were: serum creatinine levels, creatinine clearance, mean arterial pressure (MAP), urine output, and serum sodium levels evaluated at baseline and on treatment days 1, 3, 7, and 14. Results Most patients achieved serum creatinine levels <1.5 mg/dL and were considered responders (22/30, 73%), whereas eight patients (27%) were nonresponders. At baseline, responders and nonresponders differed only regarding initial bilirubin levels and international normalized ratio values. Treatment duration was 7.5±3.2 days. Responders experienced a significant (p<0.05) decrease in serum creatinine levels (from 3.26±0.48 to 1.28±0.14 mg/dL), as well as a significant increase (p<0.05) in creatinine clearance (from 21±4.1 to 67.7±12.1 mL/min), urine output (from 583±41.1 to 1163±105 mL/day), MAP (from 79.2±2.94 to 93.9±2.34 mmHg), and serum sodium levels (from 125±2.01 to 132.3±1.39 mEq/L). In nonresponders, the MAP increased, but serum creatinine levels also increased, reflecting a decrease in creatinine clearance and urine output, with no significant change in serum sodium levels over the duration of the treatment. Conclusion In most patients, noradrenaline treatment induced systemic vasoconstriction resulting in HRS reversal, with acceptable safety, in agreement with previously reported outcomes of terlipressin treatment.

Abstract
Background Hepatorenal syndrome (HRS) is a severe complication of end-stage renal disease whose management still constitutes a big challenge. Various approaches have been used for hepatorenal syndrome treatment, including vasoconstrictor therapy. Terlipressin, a vasopressin analogue, has frequently been used. Aim To evaluate the efficacy and safety of terlipressin in patients with HRS by performing a systematic review with a meta-analysis of controlled, clinical trials. Methods Only prospective, placebo-controlled, randomized clinical trials (RCTs) were included. We used the random effects model of DerSimonian and Laird, with heterogeneity and subgroups analyses. The primary end-point of interest was the HRS reversal after terlipressin (or placebo) therapy in study patients vs. control patients (as a measure of efficacy). The secondary outcome was the rate of ischemic side-effects in study patients vs. placebo patients (as a measure of tolerability). The additional end-point was the impact of terlipressin on survival in the HRS population. Results We identified five studies involving 243 unique patients with HRS. Pooling of study results showed a significant increase in HRS reversal among study (terlipressin) versus control (placebo) patients; the pooled odd ratio (OR) of HRS reversal was 8.09; 95% CI, 3.521; 18.59; p=0.0001. The p-value was 0.5 for our test of study heterogeneity. In a subgroup analysis excluding case-control trials these results did not change. The rate of severe ischemic events was higher in study than control patients, pooled OR=2.907; 95% CI, 1.094; 7.723 (p=0.032). The test for heterogeneity was not significant. Terlipressin use had no significant impact upon survival (pooled OR for survival rate, 2.064; 95% CI, 0.939; 4.538; p=0.07). No significant heterogeneity (NS) was found. Conclusions Our meta-analysis shows that terlipressin has higher efficacy than placebo in reversing renal function in the HRS population. There was no apparent impact of terlipressin therapy on survival in HRS patients but further large-size trials are needed. Terlipressin use in the HRS population requires careful selection of patients and close clinical surveillance. These results support the use of terlipressin for reversal of renal function in the HRS population.

Abstract
Acute kidney injury (AKI) is common in patients with cirrhosis and ascites on the waiting list for liver transplant. Hepatorenal syndrome (HRS) is an important cause of AKI among cirrhotics. A dynamic definition of AKI in patients with cirrhosis has been introduced and changed the diagnosis criteria. Liver transplantation remains the better option but the medical management of HRS has changed. Terlipressin plus albumin is currently the gold standard. Surgery and liver or kidney support systems have been recommended. Clinical trials will assess the most appropriate approach for the treatment of HRS in light of the revised diagnostic criteria.

Abstract
Albumin, a negatively charged globular protein encoded on chromosome 4, is one of the most abundant proteins in the plasma and accounts for approximately 75% of plasma oncotic pressure. The role of albumin in the management of various disease states has shown to be beneficial historically. Low serum albumin is a predictor of mortality and poor outcomes. In cirrhotics undergoing paracentesis, albumin infusion prevents rapid re-accumulation of ascitic fluid while simultaneously decreasing the risk of post-paracentesis related circulatory dysfunction. Additionally, albumin is utilized in patients with hepatorenal syndrome (HRS) and spontaneous bacterial peritonitis (SBP). Overall, albumin appears to be an effective pharmacological agent in the management of cirrhosis and its complications.

Abstract
Renal failure is a late consequence of end-stage liver disease (ESLD). Even with liver transplantation, pretransplant renal impairment remains a strong predictor of posttransplant mortality. This review seeks to summarize and critically appraise common therapies used in this setting, including pharmacologic agents, procedures (transjugular intrahepatic portosystemic shunt, renal replacement therapy), and simultaneous liver-kidney transplantation. More experimental extracorporal modalities, eg, albumin dialysis or bioartificial livers, will not be discussed. A brief discussion on the definition and pathophysiologic underpinnings of renal failure in ESLD will be held at the beginning to lay the groundwork for the main section.

Abstract
Anesthesia for liver transplantation pertains to a continuum of critical care of patients with end-stage liver disease. Hence, anesthesiologists, armed with a comprehensive understanding of pathophysiology and physiologic effects of liver transplantation on recipients, are expected to maintain homeostasis of all organ function. Specifically, patients with fulminant hepatic failure develop significant changes in cerebral function, and cerebral perfusion is maintained by monitoring cerebral blood flow and cerebral metabolic rate of oxygen, and intracranial pressure. Hyperdynamic circulation is challenged by the postreperfusion syndrome, which may lead to cardiovascular collapse. The goal of circulatory support is to maintain tissue perfusion via optimal preload, contractility, and heart rate using the guidance of right-heart catheterization and transesophageal echocardiography. Portopulmonary hypertension and hepatopulmonary syndrome have high morbidity and mortality, and they should be properly evaluated preoperatively. Major bleeding is a common occurrence, and euvolemia is maintained using a rapid infusion device. Pre-existing coagulopathy is compounded by dilution, fibrinolysis, heparin effect, and excessive activation. It is treated using selective component or pharmacologic therapy based on the viscoelastic properties of whole blood. Hypocalcemia and hyperkalemia from massive transfusion, lack of hepatic function, and the postreperfusion syndrome should be aggressively treated. Close communication between all parties involved in liver transplantation is also equally valuable in achieving a successful outcome.

Abstract
The progression of liver disease can cause several physiologic derangements that may precipitate hepatic failure and require admission to an intensive care unit. The underlying pathology may be acute, acute-on chronic, or chronic in nature. Liver failure may manifest with a variety of clinical signs and symptoms that need prompt attention. The compromised synthetic and metabolic activity of the failing liver affects all organ systems, from neurologic to integumentary. Supportive care and specific therapies should be instituted in order to improve outcome and minimize time of recovery. In this chapter we will discuss the definition, clinical manifestations, workup, and management of acute and chronic liver failure and the general principles of treatment of these patients. Management of liver failure secondary to certain common etiologies will also be presented. Finally, liver transplantation and alternative therapies will also be discussed.

Role of albumin in diseases associated with severe systemic inflammation: Pathophysiologic and clinical evidence in sepsis and in decompensated cirrhosis. J Crit Care 2015; 33:62-70.

Abstract
The metabolism of albumin in inflammatory states such as sepsis or major surgery is complex and still not well characterized. Nevertheless, in inflammatory states, albumin synthesis has been observed to increase. By contrast, in decompensated cirrhosis, a disease characterized by systemic inflammation, albumin synthesis by the liver may decrease to 30% to 50% of normal values. Furthermore, in these conditions, there are high capillary leakage and altered albumin kinetics. The discussion regarding the effect of exogenous albumin administration on intravascular volume in inflammatory states should therefore address albumin turnover. To add complexity to our understanding of the effects of albumin, there are many data indicating that the therapeutic action of albumin is mediated not only through the impact on plasma volume expansion but also through a modulatory effect on inflammation and oxidative stress. All these characteristics are relevant to diseases associated with systemic inflammation including sepsis and decompensated cirrhosis.

Abstract
BACKGROUND Terlipressin with albumin is recommended in hepatorenal syndrome (HRS). Terlipressin is expensive and not licensed in many countries. Alternative therapy is necessary. We compared the efficacy of terlipressin and albumin with concurrent low-dose dopamine, furosemide, and albumin in HRS. METHODS In an open-label, randomized trial, forty consecutive patients each with HRS type I and HRS type II received either concurrent infusion of terlipressin 0.5 mg for every 6 hr and albumin 20 g/day for 5 days (n = 20) or a combination of dopamine 2 μg/kg/min, furosemide 0.01 mg/kg/hr, and albumin 20 g/day (triple therapy), in one of two therapeutic arms. Twenty-four-hour urine output, urinary sodium, and plasma renin activity (PRA) were assessed before and after treatment. RESULTS The two groups were comparable at baseline in both HRS-I and II. In HRS-I, 24 hr urine output and urine sodium at the end of 5 days increased in both treatment groups (terlipressin, urine output 278 ± 136 to 765 ± 699 ml/day, P < 0.01; urine sodium 28 ± 25.1 to 39 ± 32.1 meq/l, P = 0.05. Triple therapy: urine output 219 ± 134 to 706 ± 595 ml/day, P < 0.01; urine sodium 25 ± 18.3 to 41 ± 27.5 meq/l, P < 0.01). PRA (ng/ml/hr) decreased from 28.1 ± 9.76 to 24.2 ± 9.5 (P = 0.01) and from 29.5 ± 15.8 to 27.3 ± 17.1 (P = 0.02) in the terlipressin and triple therapy groups, respectively. In HRS-II, similar significant improvement (P < 0.01) was seen in 24 hr urine output and urine sodium; decrease in PRA (P < 0.05) was documented after treatment in both the arms. Post-treatment changes in parameters were comparable between the two arms, in both HRS-I and HRS-II cases. CONCLUSIONS Concurrent triple therapy improved renal function in HRS and was less expensive than terlipressin (Registration: CTRI/2011/07/001860; www.ctri.nic.in).

Creatinine Change on Vasoconstrictors as Mortality Surrogate in Hepatorenal Syndrome: Systematic Review & Meta-Analysis. PLoS One 2015; 10:e0135625.

Abstract
BACKGROUND AND AIMS Hepatorenal syndrome is a severe complication of cirrhosis and associates with significant mortality. Vasoconstrictor medications improve renal function in patients with hepatorenal syndrome. However, it is unclear to what extent changes in serum creatinine during treatment may act as a surrogate for changes in mortality. We have performed a meta-analysis of randomized trials of vasoconstrictors assessing the association between changes in serum creatinine, taken as a continuous variable, and mortality, both while on treatment and during the follow-up period for survivors. METHODS The electronic databases of PubMed, Web of Science and Embase were searched for randomized trials evaluating the efficacy of vasoconstrictor therapy for treatment of HRS type 1 or 2. The relative risk (RR) for mortality was calculated against delta creatinine. The proportion of treatment effect explained (PTE) was calculated for delta creatinine. RESULTS Seven trials enrolling 345 patients were included. The correlation between delta creatinine and ln (RR) was moderately good (R2 = 0.61). The intercept and parameter estimate indicated a fall in creatinine while on treatment of 1 mg/dL resulted in a 27% reduction in RR for mortality compared to the control arm. In patients surviving the treatment period, a fall in creatinine while on treatment of 1 mg/dL resulted in a 16% reduction in RR for post-treatment mortality during follow-up. The PTE of delta creatinine for overall mortality was 0.91 and 0.26 for post-treatment mortality. CONCLUSIONS Changes in serum creatinine in response to vasoconstrictor therapy appear to be a valid surrogate for mortality, even in the period following the completion of treatment.

Abstract
UNLABELLED Hepatorenal syndrome (HRS), a serious complication of cirrhosis, is associated with high mortality without treatment. Terlipressin with albumin is effective in the reversal of HRS. Where terlipressin is not available, as in the United States, midodrine and octreotide with albumin are used as an alternative treatment of HRS. The aim was to compare the effectiveness of terlipressin plus albumin versus midodrine and octreotide plus albumin in the treatment of HRS in a randomized controlled trial. Twenty-seven patients were randomized to receive terlipressin with albumin (TERLI group) and 22 to receive midodrine and octreotide plus albumin (MID/OCT group). The TERLI group received terlipressin by intravenous infusion, initially 3 mg/24 hours, progressively increased to 12 mg/24 hours if there was no response. The MID/OCT group received midodrine orally at an initial dose of 7.5 mg thrice daily, with the dose increased to a maximum of 12.5 mg thrice daily, together with octreotide subcutaneously: initial dose 100 μg thrice daily and up to 200 μg thrice daily. Both groups received albumin intravenously 1 g/kg of body weight on day 1 and 20-40 g/day thereafter. There was a significantly higher rate of recovery of renal function in the TERLI group (19/27, 70.4%) compared to the MID/OCT group (6/21, 28.6%), P = 0.01. Improvement in renal function and lower baseline Model for End-Stage Liver Disease score were associated with better survival. CONCLUSION Terlipressin plus albumin is significantly more effective than midodrine and octreotide plus albumin in improving renal function in patients with HRS.

Abstract
For many years, hepatorenal syndrome was considered a uniformly and rapidly fatal complication of end-stage liver disease. Although the syndrome still carries a poor long-term prognosis, increased understanding of its hemodynamic derangements has led to new pharmacologic treatments that significantly improve short-term outcomes. In this article, Drs Tong, Hurley, and Hayashi discuss a case of remarkable reversal of hepatorenal syndrome with use of oral midodrine hydrochloride, subcutaneous octreotide acetate, and intravenous albumin. The authors highlight the great progress that has been made in this field and review new therapeutic options that are on the market or under study. It is important for physicians who are caring for patients with hepatorenal syndrome to know about and consider the available treatments before an approach of "supportive care only" is taken.

Abstract
Human serum albumin (HSA) is one of the most frequent treatments in patients with decompensated cirrhosis. Prevention of paracentesis-induced circulatory dysfunction, prevention of type-1 HRS associated with bacterial infections, and treatment of type-1 hepatorenal syndrome are the main indications. In these indications treatment with HSA is associated with improvement in survival. Albumin is a stable and very flexible molecule with a heart shape, 585 residues, and three domains of similar size, each one containing two sub-domains. Many of the physiological functions of HSA rely on its ability to bind an extremely wide range of endogenous and exogenous ligands, to increase their solubility in plasma, to transport them to specific tissues and organs, or to dispose of them when they are toxic. The chemical structure of albumin can be altered by some specific processes (oxidation, glycation) leading to rapid clearance and catabolism. An outstanding feature of HSA is its capacity to bind lipopolysaccharide and other bacterial products (lipoteichoic acid and peptidoglycan), reactive oxygen species, nitric oxide and other nitrogen reactive species, and prostaglandins. Binding to NO and prostaglandins are reversible, so they can be transferred to other molecules at different sites from their synthesis. Through these functions, HSA modulates the inflammatory reaction. Decompensated cirrhosis is a disease associated systemic inflammation, which plays an important role in the pathogenesis of organ or system dysfunction/failure. Although, the beneficial effects of HAS have been traditionally attributed to plasma volume expansion, they could also relate to its effects modulating systemic and organ inflammation.

Abstract
Hepatorenal syndrome is a severe complication of end-stage liver disease. The pathophysiological hallmark is severe renal vasoconstriction, resulting from peripheral and splanchnic vasodilation as well as activation of renal vasoconstrictor molecules, which induce the effective arterial volume reduction and the functional renal failure. The diagnosis of hepatorenal syndrome is currently based on the exclusion of other causes of renal failure (especially prerenal). Spontaneous bacterial peritonitis is one of the triggering factors and should be sought in all patients with severe liver disease and acute renal failure. Quickly treating patients with parental antibiotics and albumin infusion significantly decreases the risk. The combined use of intravenous albumin, splanchnic and peripheral vasoconstrictor and/or renal replacement therapy sometimes enables a delay until liver transplantation (or combined liver-kidney in selected patients). Transplantation is in fact the only way to improve the long-term prognosis.

Abstract
Hepatorenal syndrome is a complication of end stage liver disease. It is a unique form of functional renal failure related to kidney vasoconstriction in the absence of underlying kidney pathology. Hepatorenal syndrome is classified into 2 types: type-1 HRS shows a rapid and progressive decline in renal function with a very poor prognosis (median survival of about 2 weeks); type-2 HRS has a more stable kidney failure, with a median survival of 6 months; its main clinical manifestation is refractory ascites. The most appropriate therapy for HRS is liver transplantation but only a minority of HRS patients undergo the procedure due to the high mortality; survival among liver transplant recipients is lower in HRS than among their counterparts without HRS. A large body of evidence, based on observational studies and randomized controlled trials, has been accumulated in the last decade showing that terlipressin represents a milestone in the management of HRS. According to our meta-analysis of randomized trials comparing terlipressin vs. placebo (five trials, n=243 patients), the pooled rate of patients who reversed HRS by terlipressin was 8.09 (95% CI, 3.52; 18.59) (P<0.001). Among vasoconstrictors, terlipressin (a V1 vasopressin agonist) is the most widely used; however, noradrenaline is another good choice. Vasoconstrictor drugs alone or with albumin reduce mortality compared with no intervention or albumin (RR of mortality, 0.82; 95% Confidence Intervals, 0.70; 0.96) (P<0.01). Two series of patients with HRS recurrence after the first treatment have recently shown that long-term therapy with terlipressin and albumin is beneficial as a bridge to liver transplant. Nevertheless, recovery of renal function can be achieved in less than 50% of patients with HRS after terlipressin use and the recovery of renal function may also be partial in patients who are defined full responders. Renal replacement therapy should not be considered a first-line therapy for HRS Clinical trials are under way in order to assess efficacy and safety of novel therapeutic agents for the treatment of type-1 and type-2 HRS.

Abstract
Hepatorenal syndrome (HRS) is a severe complication of cirrhosis that is associated with poor survival. A rapid diagnosis of HRS and a prompt initiation of the treatment with terlipressin and albumin are mandatory because this leads to an improvement of prognosis. This review covers the predictive value of HRS on 3-month mortality beyond the MELD score and its consequential impact on the prioritization policy to liver transplantation (LT). Moreover, it analyzes the impact of the response to pharmacological treatment on the MELD score, its possible delaying effect on the timing of LT, and suggests a way of overcoming the paradoxical effect of terlipressin and albumin on the priority to LT in responders. Finally, the review discusses the appropriate use of combined liver-kidney transplantation (CLKT) in patients with HRS who do not respond to treatment with terlipressin and albumin.

BACKGROUND & AIMS Treatment with albumin in patients with cirrhosis and spontaneous bacterial peritonitis (SBP) prevents renal failure and improves survival. Whether albumin has similar beneficial effects in patients with infections other than SBP is unknown. METHODS One hundred and ten patients with cirrhosis hospitalized for infections other than SBP were randomly assigned to receive antibiotics plus albumin (1.5 g/kgbw at diagnosis and 1 g/kgbw at day 3) (albumin group; n=56) or antibiotics alone (control group; n=54). The primary end point was survival at 3 months. Secondary end points were effects on renal and circulatory function. RESULTS The renal function, as evaluated by differences in changes in serum creatinine and estimated glomerular filtration rate between the two groups, improved in patients treated with albumin. The circulatory function improved significantly in patients treated with albumin, but not in those from the control group. There was a trend for a lower frequency of type 1 hepatorenal syndrome in the albumin group compared to the control group (1 vs. 4 patients, respectively; p=n.s.). Probability of survival at 3 months was not significantly different among the two groups. However, when adjusted for factors with independent prognostic value, treatment with albumin was an independent predictive factor of survival. CONCLUSIONS As compared with standard antibiotic therapy alone, treatment with albumin together with antibiotics has beneficial effects on the renal and circulatory function and shows a potential survival benefit. Further studies with large sample sizes should be performed to confirm these findings.

Abstract
Hepatorenal syndrome (HRS) is defined as a functional renal failure in patients with liver disease with portal hypertension and it constitutes the climax of systemic circulatory changes associated with portal hypertension. This term refers to a precisely specified syndrome featuring in particular morphologically intact kidneys, where regulatory mechanisms have minimised glomerular filtration and maximised tubular resorption and urine concentration, which ultimately results in uraemia. The syndrome occurs almost exclusively in patients with ascites. Type 1 HRS develops as a consequence of a severe reduction of effective circulating volume due to both an extreme splanchnic arterial vasodilatation and a reduction of cardiac output. Type 2 HRS is characterised by a stable or slowly progressive renal failure so that its main clinical consequence is not acute renal failure, but refractory ascites, and its impact on prognosis is less negative. Liver transplantation is the most appropriate therapeutic method, nevertheless, only a few patients can receive it. The most suitable “bridge treatments” or treatment for patients ineligible for a liver transplant include terlipressin plus albumin. Terlipressin is at an initial dose of 0.5-1 mg every 4 h by intravenous bolus to 3 mg every 4 h in cases when there is no response. Renal function recovery can be achieved in less than 50% of patients and a considerable decrease in renal function may reoccur even in patients who have been responding to therapy over the short term. Transjugular intrahepatic portosystemic shunt plays only a marginal role in the treatment of HRS.

Abstract
Hepatorenal syndrome (HRS) is defined as the occurrence of renal dysfunction in a patient with end-stage liver cirrhosis in the absence of another identifiable cause of renal failure. The prognosis of HRS remains poor, with a median survival without liver transplantation of <6 months. However, understanding the pathogenesis of HRS has led to the introduction of treatments designed to increase renal perfusion and mean arterial blood pressure using vasopressors and albumin, which has led to improvement in renal function in ∼50% of patients.

Abstract
Hepatorenal syndrome (HRS) is a unique type of kidney failure that occurs in advanced cirrhosis. It is characterized by functional impairment of the kidneys due to vasoconstriction of the renal arteries in the setting of preserved tubular function and absence of significant histologic abnormalities. Renal vasoconstriction in HRS is due to severe vasodilation of the splanchnic arteries associated with portal hypertension, leading to a decrease in effective arterial blood volume and arterial pressure. HRS commonly develops after a trigger, usually a bacterial infection, that disrupts the arterial circulation, but it also may occur spontaneously. There are 2 forms of HRS: type 1 is characterized by an acute progressive decrease in kidney function and very short survival without treatment, whereas type 2 features stable less severe kidney failure and longer survival compared with type 1. A liver transplant is the preferred treatment for HRS. Pharmacologic treatment with vasoconstrictors to reverse splanchnic vasodilation, together with albumin, is effective in 40%-50% of patients with type 1 HRS and improves survival. The drug of choice is the vasopressin analogue terlipressin. Renal replacement therapy should not be used as first-line therapy.

Abstract
Albumin has been widely used in patients with cirrhosis in an attempt to improve circulatory and renal functions. The benefits of albumin infusions in preventing the deterioration in renal function associated with large-volume paracentesis, spontaneous bacterial peritonitis, and established hepatorenal syndrome in conjunction with a vasoconstrictor are well established. While some of these indications are supported by the results of randomized studies, others are based only on clinical experience and have not been proved in prospective studies. The paucity of well-designed trials, the high cost of albumin, the lack of a clear-cut survival benefit, and fear of transmitting unknown infections make the use of albumin controversial. The recent development of the molecular adsorbent recirculating system, an albumin dialysis, is an example of the capacity of albumin to act by mechanisms other than its oncotic effect. Efforts should be made to define the indications for albumin use, the dose required, and predictors of response, so that patients gain the maximum benefit from its administration.

Abstract
Acute kidney injury (AKI) has a major impact on short- and long-term survival in liver transplant (LT) patients. There is no currently accepted uniform definition of AKI, which would facilitate standardization of the care of patients with AKI and to improve and enhance collaborative research efforts. New promising biomarkers such as neutrophil gelatinase-associated lipocalin or kidney injury molecule-1 have been developed for the prevention of delayed AKI treatment. Early dialysis has been shown to be beneficial in patients with AKI stage III according to the classification of the Acute Kidney Injury Network, whereas treatment with loop diuretics or dopamine is associated with worse outcome. The mainstay for the prevention of AKI seems to be avoidance of volume depletion and maintenance of a mean arterial pressure >65 mmHg. Although the aetiology of chronic kidney disease in transplant recipients may be multifactorial, calcineurin-inhibitor (CNI)-induced nephrotoxicity significantly contributes to the development of renal dysfunction over time after LT. The delayed introduction of CNI at minimal doses has shown to be safe and effective for the preservation of kidney function. Other strategies to overcome CNI nephrotoxicity include CNI minimization protocols or CNI withdrawal and conversion to mycophenolate mofetil or the mammalian target of rapamycin inhibitor-based immunosuppressive regimens. However, CNI avoidance may bear a higher rejection risk. Thus, more results from randomized-controlled studies are urgently warranted to determine which drug combinations are the most beneficial approaches for the potential introduction of CNI-free immunosuppressive regimens.

Abstract
Human serum albumin (HSA), the most abundant protein in plasma, is a monomeric multi-domain macromolecule, representing the main determinant of plasma oncotic pressure and the main modulator of fluid distribution between body compartments. HSA displays an extraordinary ligand binding capacity, providing a depot and carrier for many endogenous and exogenous compounds. Indeed, HSA represents the main carrier for fatty acids, affects pharmacokinetics of many drugs, provides the metabolic modification of some ligands, renders potential toxins harmless, accounts for most of the anti-oxidant capacity of human plasma, and displays (pseudo-)enzymatic properties. HSA is a valuable biomarker of many diseases, including cancer, rheumatoid arthritis, ischemia, post-menopausal obesity, severe acute graft-versus-host disease, and diseases that need monitoring of the glycemic control. Moreover, HSA is widely used clinically to treat several diseases, including hypovolemia, shock, burns, surgical blood loss, trauma, hemorrhage, cardiopulmonary bypass, acute respiratory distress syndrome, hemodialysis, acute liver failure, chronic liver disease, nutrition support, resuscitation, and hypoalbuminemia. Recently, biotechnological applications of HSA, including implantable biomaterials, surgical adhesives and sealants, biochromatography, ligand trapping, and fusion proteins, have been reported. Here, genetic, biochemical, biomedical, and biotechnological aspects of HSA are reviewed.

Abstract
Little is known about how alcohol causes liver disease and cirrhosis. The strongest evidence of the causality between alcohol and liver disease stems from epidemiological observations. Factors contributing to alcohol-induced fibrosis and cirrhosis include cytokines, oxidative stress, and toxic metabolites of ethanol. Patients with alcoholic cirrhosis generally have complications at diagnosis, and cirrhotic complications should be actively assessed because they are closely associated with subsequent morbidity as well as mortality. Abstinence is strictly required to prevent disease progression and is critical for eventual liver transplantation. In addition, nutritional therapy remains the mainstay of managing alcoholic cirrhosis.

Abstract
BACKGROUND Vasoconstrictor therapy has been advocated as treatment for hepatorenal syndrome (HRS). Our aim was to explore across all tested vasoconstrictors whether achievement of a substantial increase in arterial blood pressure is associated with recovery of kidney function in HRS. STUDY DESIGN Pooled analysis of published studies identified by electronic database search. SETTING & POPULATION Data pooled across 501 participants in 21 studies. SELECTION CRITERIA FOR STUDIES Human studies evaluating the efficacy of a vasoconstrictor administered for 72 hours or longer in adults with HRS type 1 or 2. INTERVENTION Vasoconstrictor therapy. OUTCOMES & MEASUREMENTS Cohorts' mean arterial pressure (MAP), serum creatinine level, urinary output, and plasma renin activity (PRA) at baseline and subsequent times during treatment. Linear regression models were constructed to estimate mean daily changes in MAP, serum creatinine level, urinary output, and PRA for each study subgroup. Correlations were used to assess for association between variables. RESULTS An increase in MAP is associated strongly with a decrease in serum creatinine level, but is not associated with an increase in urinary output. Associations were stronger when analyses were restricted to randomized clinical trials and were not limited to cohorts with either lower baseline MAP or lower baseline serum creatinine level. Most studies tested terlipressin as vasoconstrictor, whereas fewer studies tested ornipressin, midodrine, octreotide, or norepinephrine. Excluding cohorts of participants treated with terlipressin or ornipressin did not eliminate the association. Furthermore, a decrease in PRA correlated with improvement in kidney function. LIMITATIONS Studies were not originally designed to test our question. We lacked access to individual patient data. CONCLUSIONS An increase in MAP during vasoconstrictor therapy in patients with HRS is associated with improvement in kidney function across the spectrum of drugs tested to date. These results support consideration for a goal-directed approach to the treatment of HRS.

Abstract
The development of hepatorenal syndrome (HRS) is related to many changes associated with advanced cirrhosis. Because vasoconstrictors correct systemic and splanchnic hemodynamic abnormalities, they are effective treatments for HRS, although only in approximately 40% of HRS patients. Emerging data show that combination treatment with vasoconstrictors and TIPS may yield better outcomes than either alone. All HRS patients should be assessed for liver transplantation. Reversing HRS before transplantation is associated with better long-term survival. Combined liver– kidney transplantation is indicated for those with irreversible kidney injury. Otherwise, there is some merit in performing a liver transplant first and only considering a kidney transplant later.

Abstract
Hepatorenal syndrome (HRS) is a functional form of acute kidney injury (AKI) associated with advanced liver cirrhosis or fulminant hepatic failure. Various new concepts have emerged since the initial diagnostic criteria and definition of HRS was initially published. These include better understanding of the pathophysiological mechanisms involved in HRS, identification of bacterial infection (especially spontaneous bacterial peritonitis) as the most important HRS-precipitating event, recognition that insufficient cardiac output plays a role in the occurrence of HRS, and evidence that renal failure reverses with pharmacotherapy. Patients with HRS are often critically ill and, by definition, have multiorgan failure. The purpose of this review is to provide an update on novel advances in HRS, with emphasis on the different aspects of management of these patients in the intensive care unit.

Abstract
INTRODUCTION Renal failure in cirrhosis is a common complication that is associated with poor survival. A rapid diagnosis of the cause of renal failure is mandatory because it is associated with prognosis. AREAS COVERED This review covers the differential diagnosis between hepatorenal syndrome (HRS) and other causes of renal failure, as well as the difficulty in making a correct diagnosis, caused by the differentiation between hepatorenal syndrome and acute tubular necrosis. This review also discusses the multifactorial mechanisms involved in the pathogenesis of HRS. The paper provides diagnostic algorithms to use in clinical practice, emphasized by the fact that some patients may have HRS superimposed on pre-existent renal failure. EXPERT OPINION The correct diagnosis of renal failure is essential to initiate the correct treatment of this complication. In patients with HRS type 1, treatment with vasopressin and albumin is the treatment of choice; however, 50% of patients do not respond to this treatment.

Abstract
Over the past 50 years, the pathophysiology and features of the hepatorenal syndrome have been illuminated. The syndrome can be divided into 2 distinct clinical patterns: a rapidly progressive renal failure with an extremely poor prognosis (type 1) and a slow progressive renal failure that correlates with the degree of cirrhosis (type 2). Although our understanding of hepatorenal syndrome continues to grow, our current methods of treating this condition remain limited in their effectiveness. The only definitive therapy is liver transplantation. This is a review of the definition, pathophysiology, and current recommendations for management of hepatorenal syndrome with the critical care nurse in mind.

Abstract
Hepatorenal syndrome (HRS) is a reversible form of functional renal failure that occurs with advanced hepatic cirrhosis and liver failure. Despite mounting research in HRS, its etiology and medical therapy has not been resolved. HRS encompasses 2 distinct types. Type 1 is characterized by the rapid development of renal failure that occurs within 2 wk and involves a doubling of initial serum creatinine. Type 2 has a more insidious onset and is often associated with ascites. Animal studies have shown that both forms, in particular type 1 HRS, are often precipitated by bacterial infections and circulatory changes. The prognosis for HRS remains very poor. Type 1 and 2 both have an expected survival time of 2 wk and 6 mo, respectively. Progression of liver cirrhosis and the resultant portal hypertension leads to the pooling of blood in the splanchnic vascular bed. The ensuing hyperdynamic circulation causes an ineffective circulatory volume which subsequently activates neurohormonal systems. Primarily the sympathetic nervous system and the renin angiotensin system are activated, which, in the early stages of HRS, maintain adequate circulation. Both advanced cirrhosis and prolonged activation of neurohormonal mechanisms result in fatal complications. Locally produced nitric oxide may have the potential to induce a deleterious vasodilatory effect on the splanchnic circulation. Currently medical therapy is aimed at reducing splanchnic vasodilation to resolve the ineffective circulation and maintain good renal perfusion pressure. Terlipressin, a vasopressin analogue, has shown potential benefit in the treatment of HRS. It prolongs both survival time and has the ability to reverse HRS in the majority of patients. In this review we aim to focus on the pathogenesis of HRS and its treatment with terlipressin vs other drugs.

Abstract
BACKGROUND The vasoconstrictor terlipressin is widely used in the treatment of the hepatorenal syndrome and variceal bleeding. However, terlipressin may compromise cardiac function and induce ischemia. AIM Therefore, we aimed to assess the effects of terlipressin on cardiac function and perfusion. METHODS Twenty-four patients with cirrhosis and ascites participated, including nine with refractory ascites. Gated myocardial perfusion imaging, mean arterial blood pressure (MAP), cardiac output (CO), ejection fraction (EF), end-diastolic volume (EDV), perfusion, and motion of the myocardium were determined before and after a bolus injection of 2 mg terlipressin. RESULTS MAP increased after terlipressin (P value of less than 0.001). EF and CO fell by -16 and -17%, respectively in the terlipressin group versus 1 and -2%, respectively in the placebo group (P value of less than 0.001 and P value of less than 0.01). In the terlipressin group, EDV increased by 18 versus -4% in the placebo group (P value of less than 0.01). Wall motion in the anterior and posterior walls fell by -18 and -22%, respectively after terlipressin treatment versus 0 and 0% in the placebo group (P value of less than 0.01). In contrast, myocardial perfusion and stroke volume were unaltered in both the groups. The change in EF during terlipressin treatment correlated significantly with the change in MAP (r=-0.60, P value <0.002). Patients with refractory ascites had a higher EF and lower EDV and ESV than the patients with nonrefractory ascites, both at baseline and after terlipressin treatment. The decrease in the left ventricular wall thickening and wall motion correlated with the Child--Pugh score, r=-0.59, P=0.005 and r=-0.48, P=0.03. CONCLUSION In advanced cirrhosis, the increase in afterload and EDV after terlipressin treatment result in a decrease in left ventricular wall motion, resulting in reduced CO and EF, but myocardial perfusion is preserved. Alteration in cardiac function at baseline and after terlipressin treatment relates to the stage of decompensation.

Abstract
OBJECTIVE Terlipressin (TP) is a potent vasoconstrictor, which is widely used in the treatment of bleeding esophageal varices and the hepatorenal syndrome. Side effects to TP are often related to skin hypoxaemia. The aim of the study was to investigate the transcutaneous oxygen pressures (TcPO(2) mmHg) after administration of 2 mg of TP. PATIENTS AND METHODS Nineteen patients with cirrhosis and ascites were included. TcPO(2) mmHg were measured continuously measured at the chest, abdominal wall and at the lower extremity at baseline and after 2 mg TP in 15 patients and placebo in 4 patients. RESULTS The mean whole body TcPO(2) decreased after TP by 34% (p < 0.005). The decrease was even more pronounced in the lower extremity: above knee -33% (50 vs. 33 mmHg, p = 0.01) and below knee -52% (52 vs. 26 mmHg, p = 0.001). Levels below 30 mmHg, were found in 60% of the patients after TP compared to 0% in the placebo group, p = 0.005. There were no significant changes in TcPO(2) after placebo. The baseline leg TcPO(2) correlated inversely with the MELD score (r = -0.64 and p < 0.003) and the increase in MAP after TP correlated inversely with TcPO(2) at the thorax (r = -0.60, p = 0.009). CONCLUSIONS Sixty percent of patients with decompensated cirrhosis develop hypoxaemia in the lower limb after one dose of TP.

Abstract
Critical care nurses occasionally confront patient conditions that are not common. One such condition is hepatorenal syndrome (HRS). Three primary processes contribute to regional alterations in circulation in the renal and splanchnic beds. These processes include effective hypovolemia from the massive release of vasoactive mediators, thereby underfilling circulation, systemic and splanchnic vasodilation along with renal vasoconstriction, and hyperdynamic circulation. A "second-hit" hypothesis, whereby a triggering event causes intravascular volume depletion, likely initiates the development of HRS. The idea of a second hit focuses the attention of the health care team on surveillance strategies to prevent or limit HRS in patients with advanced cirrhosis and ascites. The treatment goal is to restore systemic and splanchnic vasoconstriction, while promoting renal vasodilation, balance sodium, and achieve euvolemia. The critical care nurse must maintain ongoing education to care for the patient with this complex syndrome in order to prevent complications and death.

Abstract
Hepatorenal syndrome (HRS) is a functional renal failure that often occurs in patients with cirrhosis and ascites. HRS develops as a consequence of a severe reduction of effective circulating volume due to both an extreme splanchnic arterial vasodilatation and a reduction of cardiac output. There are 2 different types of HRS. Type 1 HRS, which is often precipitated by a bacterial infection, especially spontaneous bacterial peritonitis, is characterized by a rapidly progressive impairment of renal function. Despite its functional origin, the prognosis of type 1 HRS is very poor. Type 2 HRS is characterized by a stable or slowly progressive renal failure so that its main clinical consequence is not acute renal failure but refractory ascites and its impact on prognosis is less negative. New treatments (vasoconstrictors plus albumin, transjugular portosystemic shunt, and molecular adsorbent recirculating system), which were introduced in the past 10 years, are effective in improving renal function in patients with HRS. Among these treatments vasoconstrictors plus albumin can also improve survival in patients with type 1 HRS. Thus, this therapeutic approach has changed the management of this severe complication in patients with advanced cirrhosis.
