The use of urinary kidney injury molecule-1 and neutrophil gelatinase-associated lipocalin for diagnosis of hepato-renal syndrome in advanced cirrhotic patients.

BACKGROUND: Chronic liver disease is a common and important clinical problem.Hepatorenal syndrome (HRS) is a life threatening complication. Serum creatinine (Cr) remains the only conventional indicator of renal function. However, the interpretation of serum Cr level can be confounded by malnutrition and reduced muscle mass often observed in patients with severe liver disease. Here, we present a cross-sectional study to explore the sensitivity and specificity of other markers as urinary KIM-1 and NGAL for cases of HRS. METHODS: Cross-sectional study was conducted on 88 patients who were admitted to Alexandria main university hospital. Enrolled patients were divided in two groups; group 1: patients with advanced liver cirrhosis (child B and C) who have normal kidney functions while group 2: patients who developed HRS. Stata© version 14.2 software package was used for analysis. RESULTS: Group 1 included 18 males and 26 females compared to 25 males and 19 females in group 2 (p = 0.135). Only the urinary KIM-1 showed a statistically significant difference between both groups in the multivariate logistic regression analysis adjusted for gender, serum bilirubin, serum albumin, INR, serum K, AST and ALT levels. CONCLUSION: In conclusion, our study aligns with prior research, as seen in the consistent findings regarding Urinary NGAL elevation in cirrhotic patients with AKI. Urinary KIM-1, independent of Urinary NGAL, may have a role in precisely distinguishing between advanced liver cirrhosis and HRS and merits further exploration.

Hepato-Cardio-Renal Syndrome.

Hepatorenal syndrome has conventionally been regarded as a multisystem syndrome in which pathophysiologic pathways that link cirrhosis with impairment in kidney function are followed by dysfunction of several organs such as the heart. The advances in cardiac studies have helped diagnose more subtle cardiac abnormalities that would have otherwise remained unnoticed in a significant subset of patients with advanced liver disease and cirrhosis. Accumulating data suggests that in many instances, the cardiac dysfunction precedes and predicts development of kidney disease in such patients. These observations point to the heart as a key player in hepatorenal syndrome and challenge the notion that the cardiac abnormalities are either the consequence of aberrancies in hepatorenal interactions or have only minor effects. As such, the disturbances traditionally bundled within hepatorenal syndrome may indeed represent a hepatic form of cardiorenal syndrome whereby the liver affects the kidney in part through cardiorenal pathways (that is, hepato-cardio-renal syndrome).

Hepatorenal Syndrome Type 1: Diagnosis and Treatment.

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.

Hepatorenal Syndrome in Cirrhosis.

Hepatorenal syndrome (HRS) is a form of kidney dysfunction that characteristically occurs in liver cirrhosis. It is characterized by a marked impairment of kidney function in response to circulatory and hemodynamic alterations that occur in advanced stages of liver cirrhosis, aggravated by systemic inflammation and bacterial translocation. The classical definitions of the types of HRS have been recently revisited and 2 forms of HRS have been redefined: the acute form, referred to as acute kidney injury (HRS-AKI), and the chronic form, referred to as chronic kidney disease. HRS-AKI is one of the most severe forms of AKI in patients with cirrhosis and it consists of an abrupt impairment of kidney function, frequently triggered by an infection, appearing in the setting of advanced decompensated cirrhosis. Differential diagnosis with other causes of AKI is crucial because HRS-AKI requires a specific treatment. Differential diagnosis with AKI-acute tubular necrosis may be challenging and kidney biomarkers may be useful in this setting. Treatment of HRS-AKI is based on the administration of vasoconstrictor drugs in combination with volume expansion with albumin. Prognosis of HRS-AKI is poor, and the ideal definitive treatment consists of liver transplantation or simultaneous liver-kidney transplantation. HRS-AKI has a big impact on patients' quality of life. Management of HRS-AKI remains challenging in specific situations such as alcohol-associated hepatitis or metabolic-associated steatotic liver disease cirrhosis. Developing preventive measures for HRS-AKI, improving its early identification, discovering new biomarkers for differential diagnosis, and improving the response to therapy are some of the unmet needs in the field of HRS-AKI.

Hepatorenal Syndrome With Acute Kidney Injury: Diagnosis and Medical Management.

OBJECTIVES: To review the current definitions and diagnostic criteria for acute kidney injury (AKI) and type 1 hepatorenal syndrome (HRS) now termed HRS-AKI and discuss the challenges in deciding the most appropriate medication regimens to treat patients with HRS-AKI. DATA SOURCES: PubMed (inception to April 2023) with bibliographies of retrieved articles searched for additional articles; organizational websites for clinical practice guidelines (CPGs). STUDY SELECTION AND DATA EXTRACTION: Randomized controlled trials (RCTs) evaluating albumin and vasoconstrictors for HRS-AKI. DATA SYNTHESIS: A major change in the most recent revision of definitions and diagnostic criteria for HRS-AKI is the elimination of the set cutoff serum creatinine values for AKI. This change should be considered when comparing studies of HRS-AKI over time. Albumin has been administered to both vasoconstrictor treatment and placebo groups in all recent RCTs; however, there has never been a large RCT evaluating a no-albumin group. Most prospective trials comparing a midodrine/octreotide combination or norepinephrine to placebo or terlipressin have enrolled less than 100 patients limiting any conclusions regarding clinically important outcomes. Terlipressin with albumin has shown mixed results for complete HRS-AKI reversal with no reductions in crude mortality but adverse effect concerns involving ischemic and pulmonary events. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: Type 1 hepatorenal syndrome with acute kidney injury is a potentially life-threatening syndrome with diagnostic and treatment challenges. Albumin plus a vasoconstrictor has become the routine HRS-AKI treatment even though there has not been a large RCT evaluating a no-albumin group. Terlipressin is the vasoconstrictor of choice for HRS-AKI in current CPGs, but it has adverse effect concerns and, until recently, was not available in the United States. CONCLUSIONS: In conjunction with changes in the definitions and diagnostic criteria for HRS-AKI, debate continues regarding the optimal therapy for HRS-AKI, particularly considering recent trials demonstrating ischemic and pulmonary adverse events with terlipressin used in combination with albumin.

Analyzing the utility of renal replacement therapy to manage hepatorenal syndrome in alcoholic hepatitis without liver transplantation: a nationwide analysis.

BACKGROUND: Hepatorenal syndrome (HRS) frequently complicates alcoholic hepatitis (AH) and portends poor survival in this population. Published literature indicates mixed benefits from renal replacement therapy (RRT) for HRS refractory to medical management. Therefore, we sought to assess the utilization of RRT in AH and clinical outcomes at a national level. METHODS: Using the International Classification of Diseases, Tenth Revision (ICD-10) codes, we identified adult patients with AH with a coexisting diagnosis of HRS from the National Readmission Database 2016 through 2019. Mortality, morbidity, and resource utilization were compared. We compared proportions using the Fisher exact test and computed adjusted P-values based on multivariate regression analysis. Analyses were performed using Stata, version 14.2, considering a two-sided P < 0.05 as statistically significant. RESULTS: A total of 73 203 patients with AH were included in the analysis (mean age 46.2 years). A total of 3620 individuals had HRS diagnosis (5%), of which 14.7% (n: 532) underwent RRT. HRS patients receiving RRT had a higher mortality rate than those who did not (adjusted odds ratio [aOR] 1.8, 95% confidence interval [CI]: 1.3-2.6, P: 0.01), along with higher resource utilization. Only those patients with HRS who underwent liver transplantation (LT) experienced a mortality reduction (24.4% for those not receiving RRTs and 36.5% for those receiving RRT). CONCLUSIONS: RRT is associated with higher mortality and morbidity when offered to patients with AH and HRS, who do not undergo LT. Therefore, our results suggest careful selection of AH patients when deciding to initiate RRT for HRS.

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.

Hepatorenal Syndrome-Novel Insights into Diagnostics and Treatment.

Hepatorenal syndrome (HRS) is a disorder associated with cirrhosis and renal impairment, with portal hypertension as its major underlying cause. Moreover, HRS is the third most common cause of acute kidney injury, thus creating a major public health concern. This review summarizes the available information on the pathophysiological implications of HRS. We discuss pathogenesis associated with HRS. Mechanisms such as dysfunction of the circulatory system, bacterial infection, inflammation, impaired renal autoregulation, circulatory, and others, which have been identified as critical pathways for development of HRS, have become easier to diagnose in recent years. Additionally, relatively recently, renal dysfunction biomarkers have been found indicating renal injury, which are involved in the pathophysiology of HRS. This review also summarizes the available information on the management of HRS, focusing on vasoconstrictive drugs, renal replacement therapy, and liver transplant together with currently being investigated novel therapies. Analyzing new discoveries for the underlying causes of this condition assists the general research to improve understanding of the mechanism of pathophysiology and thus prevention of HRS.

[Hepatorenal Syndrome].

Hepatorenal syndrome (HRS) is a critical and potentially life-threatening complication of advanced liver disease, including cirrhosis. It is characterized by the development of renal dysfunction in the absence of underlying structural kidney pathology. The pathophysiology of HRS involves complex interactions between systemic and renal hemodynamics, neurohormonal imbalances, and the intricate role of vasoconstrictor substances. Understanding these mechanisms is crucial for the timely identification and management of HRS. The diagnosis of HRS is primarily clinical and relies on specific criteria that consider the exclusion of other causes of renal dysfunction. The management of HRS comprises two main approaches: vasoconstrictor therapy and albumin infusion, which aim to improve renal perfusion and mitigate the hyperdynamic circulation often seen in advanced liver disease. Additionally, strategies such as liver transplantation and renal replacement therapy are essential considerations based on individual patient characteristics and disease severity. This review article provides a comprehensive overview of hepatorenal syndrome, focusing on its pathophysiology, diagnostic criteria, and current management strategies.

Securing the diagnosis of HRS-AKI: implications for current therapies.

INTRODUCTION: Hepatorenal syndrome (HRS)-acute kidney injury (HRS-AKI) is a specific type of kidney injury seen in patients with cirrhosis and ascites and is associated with high mortality and morbidity. It is characterized by rapid deterioration of renal function due to reduced renal blood flow secondary to portal hypertensive splanchnic and systemic vasodilation. Early diagnosis and treatment of HRS-AKI are associated with greater likelihood of improvement in renal function, lower need for dialysis, and better post-transplant outcomes. AREAS COVERED: This review discusses the diagnostic criteria for HRS-AKI, which has undergone several key changes over the last decade, with an aim to secure an early diagnosis and aid swift treatment initiation. Additionally, this review outlines the current treatment paradigms for HRS-AKI. EXPERT OPINION: In the last 20 years, there have been several advances in understanding the pathophysiology and natural course of HRS-AKI. These have led to critical changes in its definition and diagnostic algorithm. However, prognosis of HRS-AKI remains dismal with no significant improvement in HRS-AKI reversal or HRS-related mortality over this time. We discuss several gaps in the current understanding and management of HRS-AKI that will benefit from further research.

Acute kidney injury in patients with cirrhosis - practical summary.

Acute kidney injury (AKI) is a relatively common condition in patients with advanced liver disease and which is associated with increased mortality. It mainly affects patients with decompensated cirrhosis, particularly those with advanced portal hypertension and ascites. The dual organ involvement may have different forms. The contributing pathogenetic mechanisms are common and predict a dismal prognosis. Early diagnosis and interventions involving specialists (in particular, hepatologists and nephrologists) are essential to improve outcomes.

Essentials of Liver Transplantation in the Setting of Acute Kidney Injury and Chronic Kidney Disease.

Kidney dysfunction is common among liver transplant candidates with decompensated cirrhosis and has a major impact on pre- and post-liver transplant survival. Updated definitions of acute kidney injury and criteria for the diagnosis of hepatorenal syndrome allow for early recognition and intervention, including early initiation of vasoconstrictor therapy for hepatorenal syndrome. The rise of the metabolic syndrome and nonalcoholic fatty liver disease as a cause of cirrhosis has coincided with an increase in intrinsic chronic kidney disease recognized in transplant candidates and recipients. Ultimately, the ability to accurately assess kidney function and associated risk is essential to decision-making in the context of transplantation, including selection of candidates for simultaneous liver and kidney transplantation.

[Guidelines on the management of ascites in cirrhosis (2023 version)].

Chinese Society of Hepatology of Chinese Medical Association organized relevant experts to update the Guidelines on the management of ascites and complications in cirrhosis in 2017 and renamed it as Guidelines on the management of ascites in cirrhosis. It provides guiding recommendations for the diagnosis and treatment of cirrhotic ascites, spontaneous bacterial peritonitis (SBP) and hepatorenal syndrome (HRS).

Renal damage in Hepatorenal Syndrome: A still unsolved issue.

Acute kidney injury (AKI) is a common complication of cirrhosis, burdened by high morbidity and mortality rates and progression to chronic kidney disease. Hepatorenal syndrome (HRS) is a peculiar type of functional AKI observed in cirrhotic patients with ascites. HRS diagnosis is still clinical, once pre-renal azotemia and intrinsic kidney damage have been excluded by applying well-established and internationally adopted criteria. HRS is considered reversible because of the absence of intrinsic renal damage. However, HRS reversibility has been questioned, due to the lack of response to treatment with vasoconstrictors plus albumin in a relevant percentage of patients and to the persistence of renal dysfunction in HRS patients who underwent liver transplantation (LT). Indeed, LT is the only ultimate treatment, as it solves both liver failure and portal hypertension. Thus, the presence of renal damage in HRS can be hypothesized. In this scenario, neutrophil gelatinase-associated lipocalin (NGAL), one of the most promising biomarkers, may help in characterizing the type of renal injury, distinguishing between HRS and acute tubular necrosis. This review gathers the available evidence in favor and against the presence of structural lesions in HRS in terms of either renal histology and urinary biomarkers with a particular focus on NGAL. The ability to properly characterize which component of renal dysfunction prevails - functional rather than structural - entails a relevant clinical impact for the treatment of these patients, both in terms of medical therapy and liver vs. combined liver-kidney transplantation.

Outcomes of patients with hepatorenal syndrome undergoing liver transplantation in the era of terlipressin.

BACKGROUND: The efficacy of terlipressin in improving pre-liver transplant renal function in hepatorenal syndrome (HRS) has been well documented, however, its impact on post-transplant renal function remains poorly described. This study aims to describe the impact of HRS and terlipressin on post-liver transplant renal function and survival. METHODS: A single-centre, retrospective, observational study was conducted to identify post-transplant outcomes of patients diagnosed with HRS undergoing liver transplant (HRS cohort) and those undergoing transplant for non-HRS, non-hepatocellular carcinoma cirrhotic indications (comparator cohort) between January 1997 and March 2020. The primary outcome was serum creatinine at 180 days post-liver transplant. Other renal outcomes and overall survival were secondary outcomes. RESULTS: 109 patients with HRS and 502 comparator patients underwent liver transplant. The comparator cohort was younger than the HRS cohort (53 vs. 57 years, P < 0.001). The median creatinine at day 180 post-transplant was higher in the HRS transplant group (119 µmol/L vs. 103 µmol/L, P < 0.001), however, this association lost significance following multivariate analysis. Seven patients (7%) in the HRS cohort received a combined liver-kidney transplant. There was no significant difference in the 12-month post-transplant survival between the two groups (94% vs. 94%, P = 0.5). CONCLUSION: Patients with HRS treated with terlipressin who subsequently undergo liver transplantation have post-transplant renal and survival outcomes comparable to patients transplanted for cirrhosis without HRS. This study supports the practice of liver-only transplant in this cohort and the reservation of renal allografts for those who have primary renal disease.

Terlipressin in combination with albumin as a therapy for hepatorenal syndrome in patients aged 65 years or older.

INTRODUCTION AND OBJECTIVES: Clinical data for older patients with advanced liver disease are limited. This post hoc analysis evaluated the efficacy and safety of terlipressin in patients aged ≥65 years with hepatorenal syndrome using data from 3 Phase III, randomized, placebo-controlled studies (OT-0401, REVERSE, CONFIRM). PATIENTS AND METHODS: The pooled population of patients aged ≥65 years (terlipressin, n = 54; placebo, n = 36) was evaluated for hepatorenal syndrome reversal-defined as a serum creatinine level ≤1.5 mg/dL (≤132.6 µmol/L) while receiving terlipressin or placebo, without renal replacement therapy, liver transplantation, or death-and the incidence of renal replacement therapy (RRT). Safety analyses included an assessment of adverse events. RESULTS: Hepatorenal syndrome reversal was almost 2-times higher in terlipressin-treated patients compared with patients who received placebo (31.5% vs 16.7%; P = 0.143). Among surviving patients, the need for RRT was significantly reduced in the terlipressin group, with an almost 3-times lower incidence of RRT versus the placebo group (Day 90: 25.0% vs 70.6%; P = 0.005). Among 23 liver-transplant-listed patients, significantly fewer patients in the terlipressin versus placebo group needed RRT by Days 30 and 60 (P = 0.027 each). Fewer patients in the terlipressin group needed RRT post-transplant (P = 0.011). More terlipressin-treated patients who were listed for and received a liver transplant were alive and RRT-free by Day 90. No new safety signals were revealed in the older subpopulation compared with previously published data. CONCLUSIONS: Terlipressin therapy may lead to clinical improvements in highly vulnerable patients aged ≥65 years with hepatorenal syndrome.

Hepatorenal Syndrome: Pathophysiology, Diagnosis, and Treatment.

Hepatorenal syndrome (HRS) is a primarily functional form of acute kidney injury (AKI) that develops in patients with decompensated cirrhosis. The pathophysiologic cascade that leads to HRS begins with pooling of blood in the splanchnic system, resulting in a decrease in effective circulating arterial volume. The definitive treatment of HRS is liver transplantation. When this is not possible, HRS is treated with a combination of vasoconstrictor agents and intravenous albumin. Although the combination of midodrine and octreotide is used in the United States, the recently approved terlipressin, an analog of vasopressin, is likely to become the first-line standard of care.

AKI-HRS, more than a name change for type-1 hepatorenal syndrome.

Acute renal failure (ARF) development is likely the most relevant event in the natural history of severely decompensated cirrhosis. It is a common complication affecting 20-49% of inpatients with decompensated cirrhosis. Also, its presence is associated with a notable increase in morbidity and mortality, and hampers management of classical cirrhosis decompensations such as ascites or hepatic encephalopathy.

Precipitating Factors and Outcome of Hepatorenal Syndrome in Liver Cirrhosis.

INTRODUCTION: Hepatorenal syndrome (HRS) is a functional renal failure due to intense renal vasoconstriction that frequently develops in patients with cirrhosis. Past studies reported that in almost half of the cases of HRS, one or more precipitating factors can be identified. We conducted a study to determine the Precipitating factors and outcome of hepatorenal Syndrome in liver cirrhosis. MATERIALS: This cross-sectional analytical study was conducted in tertiary care centre. A total of 62 consecutive patients admitted with HRS were included in this study. All adult patients admitted with diagnosis chronic liver disease with hepatorenal syndrome after applying exclusion criteria. The precipitants of HRS were correlated with the type of HRS; length of hospital stay and mortality. RESULT: Among the 62 subjects, 52% were alcoholics who were predominantly male and they had alcoholic cirrhosis. 21% and 16% were affected by hepatitis B and C respectively. Remaining 11% of them had non-alcoholic fatty liver disease. Bacterial infection and Large volume paracentesis had the longest duration of stay 16 ± 2 days and 12 deaths, GI bleed was around 12 ± 1 days and 4 deaths, ug induced HRS had 8 ± 2 days and 2 deaths, unknown factors were 5 ± 2 days. CONCLUSION: Patients presenting with two or more precipitating factors and advanced grade of HE had a prolonged hospital stay and increased mortality rate. Spontaneous bacterial infection was the most common precipitating factor at our centre. References Ginès A, Escorsell A, Ginès P, et al.
