Key recommendations

Topics 1. Overall management of DC – – Suppression of aetiological factor(s) Treatment of key pathogenic factors 2. Management of specific complications of DC – – – – – Ascites Refractory ascites Hepatic hydrothorax Hyponatremia Gastrointestinal bleeding Bacterial infections Renal impairment Acute-on-chronic liver failure Relative adrenal insufficiency Cardiopulmonary complications EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024 Click on a topic to skip to that section

Overall management of DC • Management should aim to prevent progression, not treat complications • No treatment exists that can act on cirrhosis progression directly • Two alternative approaches can be taken: – Suppress aetiological factor(s) that cause liver inflammation and cirrhosis development – Target key factors in the pathogenesis of cirrhosis decompensation and progression EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Suppression of aetiological factor(s) • Impact is variable • Probably depends on the status of liver disease at the time Recommendation Grade of evidence Grade of recommendation In patients with DC the aetiological factor should be removed, particularly alcohol consumption and hepatitis B or C virus infection, as this strategy is associated with decreased risk of decompensation and increased survival EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024 II-2 1

Treatment of key pathogenic factors • Several strategies have been evaluated to prevent disease progression in patients with DC – Targeting microbiome abnormalities and bacterial translocation to improve the gut–liver axis (i. e. rifaximin) – Improving the disturbed circulatory function (i. e. long-term albumin) – Treating the inflammatory state (i. e. statins) – Targeting portal hypertension (i. e. β-blockers) Further clinical research is needed to confirm the safety and potential benefits of these therapeutic approaches to prevent cirrhosis progression in patients with DC EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Ascites • Most common complication of decompensation in cirrhosis – Develops in 5– 10% of patients with compensated cirrhosis per year • Significant impact on patients – – – Impairs patient working and social life Frequently leads to hospitalization Requires chronic treatment Direct cause of further complications Poor prognosis (5 -year survival, ~30%) • Ascites can be uncomplicated or refractory – Ascites is uncomplicated when not infected, refractory or associated with impairment of renal function EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: evaluation and diagnosis • Cirrhosis is responsible for 80% of cases of ascites • Initial patient evaluation: – – History Physical examination Abdominal ultrasound Laboratory assessment • Liver and renal function, serum and urine electrolytes, analysis of ascitic fluid • Ascites is graded based on amount of fluid in the abdominal cavity Grading of ascites* Grade 1 Mild ascites: only detectable by ultrasound examination Grade 2 Moderate ascites: manifest by moderate symmetrical distension of abdomen Grade 3 Large or gross ascites: provokes marked abdominal distension *Ascites recurring on ≥ 3 occasions within a 12 -month period despite dietary sodium restriction and adequate diuretic dosage are considered recurrent EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: evaluation and diagnosis • Diagnostic paracentesis is indicated in: * – All patients with new-onset grade 2 or 3 ascites – Patients hospitalized for worsening ascites or any complication of cirrhosis Recommendation Grade of evidence Grade of recommendation Neutrophil count and culture of ascitic fluid culture† should be performed to exclude bacterial peritonitis • Neutrophil count >250 cells/µl denotes SBP II-2 1 Ascitic total protein concentration should be performed to identify patients at higher risk of developing SBP‡ II-2 1 The SAAG should be calculated when the cause of ascites is not immediately evident, and/or when conditions other than cirrhosis are suspected§ II-2 1 Cytology should be performed to differentiate malignancy-related from non-malignant ascites II-2 1 *Grade of evidence II-2, grade of recommendation 1; †Bedside inoculation blood culture bottles with 10 ml fluid each; ‡A total protein concentration <1. 5 g/dl is generally considered a risk factor for SBP; §SAAG ≥ 1. 1 g/dl indicates that portal hypertension is involved in ascites formation with an accuracy of about 97% EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: prognosis • Development of ascites in patients with cirrhosis is associated with a poor prognosis – 1 -year mortality: 40% – 2 -year mortality: 50% • Patients with ascites should be considered for referral for LT Recommendation Grade of evidence Grade of recommendation Since the development of grade 2 or 3 ascites in patients with cirrhosis is associated with reduced survival, LT should be considered as a potential treatment option II-2 1 • Patients may not receive adequate priority in transplant lists – Most commonly used prognostic scores can underestimate mortality risk • Improved methods to assess prognosis in these patients are needed EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: management • Grade 1 or mild ascites – No data on evolution and not known if treatment modifies natural history • Grade 2 or moderate ascites – Hospitalization not required – Correct sodium imbalance: • Dietary restriction and increased renal excretion with diuretics Recommendation Grade of evidence Moderate restriction of sodium intake (80– 120 mmol/day, corresponding to 4. 6– 6. 9 g of salt) is recommended Grade of recommendation I 1 Generally equivalent to a no added salt diet with avoidance of pre-prepared meals. Adequate nutritional education of patients on how to manage dietary sodium is also recommended II-2 1 Very low sodium diets (<40 mmol/day) should be avoided II-2 1 III 1 Prolonged bed rest cannot be recommended EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: recommended diuretics • Mainstay of medical treatment are anti-mineralocorticoid drugs* • Loop diuretics may be added in patients with long-standing ascites Recommendation Grade of evidence Grade of recommendation First episode of grade 2 ascites • Anti-mineralocorticoid drug alone (from 100 mg/day with 100 mg stepwise increased every 72 hours to a maximum of 400 mg/day if no response to lower doses) I 1 In patients who do not respond to anti-mineralocorticoids† or who develop hyperkalaemia, furosemide should be added (from 40 mg/day with 40 mg stepwise increases to a maximum of 160 mg/day) I 1 Long-standing or recurrent ascites • Combination of an anti-mineralocorticoid drug and furosemide (dose increased sequentially according to response) I 1 Torasemide can be given in patients exhibiting a weak response to furosemide I 2 *Spironolactone, canrenone or K-canrenoate; †Body weight reduction <2 kg/week EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: considerations prior to initiating diuretics • Patients with cirrhosis and ascites are highly susceptible to rapid reductions in extracellular fluid volume – Can lead to renal failure and hepatic encephalopathy Recommendation Grade of evidence Grade of recommendation GI haemorrhage, renal impairment, hepatic encephalopathy, hyponatraemia, or alterations in serum potassium concentration, should be corrected before starting diuretic therapy • In these patients, cautious initiation of diuretic therapy and frequent clinical and biochemical assessments should be performed III 1 Diuretic therapy is generally not recommended in patients with persistent overt hepatic encephalopathy III 1 EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: monitoring of patients receiving diuretics • Loop diuretics can lead to potassium and magnesium depletion and hyponatraemia • Muscle cramps can impair quality of life in patients receiving diuretics Recommendation Grade of evidence Grade of recommendation Frequent clinical and biochemical monitoring during the first weeks of treatment (particularly on first presentation) I 1 II-2 1 Once ascites have largely resolved, the dose of diuretics should be reduced to the lowest effective dose III 1 Discontinue diuretics in case of severe hyponatraemia, * AKI, worsening hepatic encephalopathy, or incapacitating muscle cramps III 1 Discontinue furosemide for severe hypokalaemia (<3 mmol/L ) Discontinue anti-mineralocorticoids for hyperkalaemia (>6 mmol/L) III 1 Albumin infusion or baclofen administration† are recommended in patients with muscle cramps I 1 Recommended maximum weight loss: 0. 5 kg/day in patients without oedema, 1 kg/day in patients with oedema *Serum sodium <125 mmol/L; † 10 mg/day, with a weekly increase of 10 mg/day up to 30 mg/day EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: management of Grade 3 ascites • Grade 3 or large ascites – LVP, under strict sterile conditions, is the treatment of choice • Ascites should be completely removed in a single session* – Contraindications to LVP include: • Uncooperative patient, abdominal skin infection at puncture sites, pregnancy, severe coagulopathy, severe bowel distention Recommendation Grade of evidence Grade of recommendation LVP should be followed with plasma volume expansion I 1 Plasma volume expansion should be performed by albumin infusion (8 g/L ascites) • For >5 L of ascites: more effective than other plasma expanders • For <5 L of ascites (low risk of PPCD): treat with albumin due to concerns about use of alternative plasma expanders I 1 III 1 After LVP, patients should receive the minimum dose of diuretics necessary to prevent re-accumulation of ascites I 1 When needed, LVP should be performed in patients with AKI or SBP III 1 *Grade of evidence I, grade of recommendation 1 EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Uncomplicated ascites: contraindicated drugs • Patients with DC and ascites are at increased risk of renal impairment from several types of drug Recommendation Grade of evidence Grade of recommendation NSAIDs should not be used (high risk of developing further sodium retention, hyponatraemia, and AKI) II-2 1 Angiotensin-converting enyzme inhibitors, angiotensin II antagonists, or 1 -adrenergic receptor blockers should not generally be used (increased risk of renal impairment) II-2 1 Aminoglycosides are discouraged (increased risk of AKI) • Reserved for patients with severe bacterial infections that cannot be treated with other antibiotics II-2 1 II 2 III 1 Contrast media • In patients with preserved renal function: does not appear to be associated with increased risk of renal impairment • In patients with renal failure: insufficient data, cautious use and preventative measures recommended EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Refractory ascites: definition • International Ascites Club: – “Ascites that cannot be mobilized or the early recurrence of which (after LVP) cannot be satisfactorily prevented by medical therapy” Refractory ascites Diuretic resistant Diuretic intractable Ascites that cannot be mobilized or the early recurrence of which cannot be prevented because of a lack of response to sodium restriction and diuretic treatment Ascites that cannot be mobilized or the early recurrence of which cannot be prevented because of the development of diuretic-induced complications that preclude the use of an effective diuretic dosage EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Refractory ascites: diagnostic criteria Diagnostic criteria Treatment duration Patients must be on intensive diuretic therapy* for at least 1 week and on a salt-restricted diet of less than 90 mmol/day Lack of response Mean weight loss of <0. 8 kg over 4 days and urinary sodium output less than the sodium intake Early ascites recurrence Reappearance of grade 2 or 3 ascites within 4 weeks of initial mobilization • HE: development of encephalopathy in the absence of any other precipitating factor • Renal impairment: increase of serum creatinine by >100% to a value >2 mg/dl (177 µmol/L) in patients with ascites responding to Diuretic-induced treatment complications • Hyponatraemia: a decrease of serum sodium by >10 mmol/L to a serum sodium of <125 mmol/L • Hypo- or hyperkalaemia: a change in serum potassium to <3 mmol/L or >6 mmol/L despite appropriate measures • Incapacitating muscle cramps *Spironolactone 400 mg/day and furosemide 160 mg/day EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Refractory ascites: diagnosis • Refractory ascites is associated with a poor prognosis – Median survival around 6 months Recommendation Grade of evidence Grade of recommendation The diagnosis of refractory ascites relies on the assessment of the response of ascites to diuretic therapy and salt restriction • Evaluation should be done in stable patients without associated complications, such as bleeding or infection, after ascertaining patient compliance to treatment III 1 Patients with refractory ascites should be evaluated for LT III 1 EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Refractory ascites: management • LVP is a safe and effective treatment – Should be associated with albumin administration to prevent PPCD • Drug treatments are controversial or inadequately studied Recommendation Grade of evidence Grade of recommendation Repeated LVP plus albumin (8 g/L of ascites removed) are recommended as first-line treatment for refractory ascites I 1 Diuretics should be discontinued in patients with refractory ascites who do not excrete >30 mmol/day of sodium under diuretic treatment III 1 II-2 1 I 2 Although controversial data exist on the use of NSBBs in refractory ascites, caution should be exercised in severe cases* • High doses of NSBB should be avoided (i. e. propranolol >80 mg/day) • Carvedilol can not be recommended at present *See also section on gastrointestinal bleeding EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Refractory ascites: indications for TIPS • TIPS decompresses the portal system* – Short term: accentuates peripheral arterial vasodilation – Within 4– 6 weeks: improves effective volaemia and renal function to increase renal sodium excretion Recommendation Grade of evidence Grade of recommendation Patients should be evaluated for TIPS insertion when: • There is refractory or recurrent ascites • Paracentesis is ineffective I III 1 1 TIPS insertion is recommended in patients: • With recurrent ascites as it improves survival • With refractory ascites as it improves the control of ascites I I 1 1 II-2 III 1 1 The use of small-diameter PTFE-covered stents is recommended to reduce the risk of TIPS dysfunction and hepatic encephalopathy After TIPS insertion, continue the following until ascites resolution: • Diuretics and salt restriction • Close clinical follow-up *By shunting an intrahepatic portal branch into a hepatic vein EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Hepatic hydrothorax: definition and diagnosis • Definition – Accumulation of transudate in the pleural space • In the absence of cardiac, pulmonary or pleural disease – Ascites moves through small diaphragmatic defects • Negative intrathoracic pressure induced by inspiration – Can lead to respiratory failure – Can be complicated by spontaneous bacterial infections (empyema) – Associated with poor prognosis • Median survival: 8 12 months • Diagnosis – Once pleural effusion has been ascertained, cardiopulmonary and primary pleural diseases should be excluded* – Diagnostic thoracentesis is required to rule out bacterial infection* *Grade of evidence III, grade of recommendation 1 EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Hepatic hydrothorax: treatment • First-line management relies on treatment of ascites with diuretics and/or LVP – Not rare for pleural effusion to persist (refractory hepatic hydrothorax) • Therapeutic thoracentesis is required to relieve dyspnoea Recommendation Grade of evidence Grade of recommendation Patients with hydrothorax should be evaluated for LT III 1 Diuretics and thoracentesis are recommended as the first-line management of hepatic hydrothorax III 1 II-2 1 Therapeutic thoracentesis is indicated in patients with dyspnoea • Chronic pleural drainage should not be performed because of the frequent occurrence of complications EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Hepatic hydrothorax: beyond diuretics and thoracentesis • Other treatments are appropriate in selected patients Recommendation Grade of evidence Grade of recommendation In selected patients, TIPS insertion for recurrent symptomatic hepatic hydrothorax is recommended II-2 1 Pleurodesis can be suggested to patients with refractory hepatic hydrothorax not amenable to LT or TIPS insertion • The frequent occurrence of side effects restricts its use to selected patients I 2 II-2 2 Mesh repair of diaphragmatic defects is suggested for the management of hepatic hydrothorax in very selected patients • The best results are achieved in patients with non-advanced cirrhosis without renal dysfunction EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Hyponatraemia • Common in patients with advanced cirrhosis – Arbitrarily defined as serum sodium concentration <130 mmol/L • Hypo- and hypervolaemic hyponatraemia can occur • Associated with: – Increased mortality and morbidity, particularly neurological complications – Reduced survival after LT Recommendation Grade of evidence Grade of recommendation Patients with cirrhosis who develop hyponatraemia should be evaluated for LT II-2 1 Removal of the cause and administration of normal saline are recommended in the management of hypovolaemic hyponatraemia III 1 Fluid restriction* to 1, 000 ml/day is recommended in the management of hypervolaemic hyponatraemia since it may prevent a further reduction in serum sodium levels III 1 *Beyond fluid restriction, hypertonic saline should be limited to rare patients with life-threatening complications. It can be considered in patients with severe hyponatraemia who are expected to undergo LT within days. Correction of serum sodium concentration after attenuation of symptoms should be slow (≤ 8 mmol/L per day) to avoid irreversible neurological sequelae (II-3; 1). Albumin can be administered but data are very limited (II-3; 2). Use of vaptans should be limited to clinical trials (III; 1) EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Variceal haemorrhage: pathophysiology and natural history • Occurs when variceal wall ruptures due to excessive wall tension – Portal pressure is a key factor in both rupture and severity of bleeding • 70% of GI bleeding events result from VH in patients with portal hypertension – Second most common decompensating event – Most severe and immediate life threatening complication Recommendation Grade of evidence Grade of recommendation Patients with DC are at high risk and should have an OGD to screen for varices, unless previously diagnosed and treated II-2 1 If OGD is performed, the presence, size and presence of red wale marks should be reported II-2 1 III 2 In patients without varices in whom aetiological factor persists and/or remain decompensated, screening OGD should be repeated yearly • In other patients the screening interval could be prolonged, but the exact interval is unclear and more data are required EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Variceal haemorrhage: prevention and treatment • High risk of death when VH occurs in patients with DC – Strategies to adequately treat VH and prevent (re)bleeding and death should be actively pursued Recommendation Grade of evidence Grade of recommendation Primary prophylaxis must be initiated upon detection of high-risk varices* because of increased risk of VH I 1 Patients with small varices with red wale marks or Child–Pugh C should be treated with NSBBs III 1 III 2 II-2 2 Patients with medium–large varices should be treated with either NSBBs or EBL • Choice of treatment can be based on local resources and expertise, patient preference, contraindications and AEs • NSBBs could be preferred because in addition to lowering portal pressure, they also exert other potential beneficial effects *High-risk = small varices with red signs, medium or large varices irrespective of Child–Pugh classification or small varices in Child–Pugh C patients EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Variceal haemorrhage: prophylaxis with NSBBs and EBL • NSBBs and EBL are equally effective in preventing first bleeding in patients with high-risk varices – Choice between options depends on factors such as patient preference, contraindications or adverse events Recommendation Grade of evidence Grade of recommendation Ascites is not a contraindication for NSBBs. However, caution should be exercised in cases of severe or refractory ascites • High doses of NSBBs should be avoided • The use of carvedilol can not be recommended at present NSBBs should be discontinued in patients with progressive hypotension or those who develop an acute intercurrent condition* After recovery, reinstatement of NSBBs can be attempted • When NSBB intolerance or contraindications persist, patient’s bleeding risk should be managed by expeditious EBL *Such as bleeding, sepsis, SBP or AKI EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024 I 1 II-2 I 1 2 III 1 III 2 1

Variceal haemorrhage: prevention of variceal rebleeding • NSBBs and EBL in combination reduces the risk of re-bleeding compared with monotherapy Recommendation Combination therapy of NSBBs + EBL is recommended I 1 Covered TIPS placement is recommended in patients who continue to be intolerant to NSBBs* III 1 *Provided that there are no absolute contraindications EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Variceal haemorrhage: management of acute GI bleeding • Medical emergency: high rate of complications and mortality in DC Acute GI bleed + portal hypertension Airway Breathing Circulation Initial assessment* and resuscitation • ENDOSCOPY Immediate start of vasoactive drug therapy† Antibiotic prophylaxis (I; 1) ‡ Early diagnostic endoscopy (<12 hours) Confirm variceal bleeding Endoscopic band ligation + ENDOSCOPY Balloon tamponade or oesophageal stenting (if massive bleeding) – Requires immediate treatment and close monitoring • Volume replacement with colloids and/or crystalloids should be initiated promptly (III; 1) Starch should not be used (I; 1) Restrictive transfusion is recommended in most patients (Hb threshold, 7 g/dl; target range 7– 9 g/dl) (I; 1) Maintain drug therapy for 3– 5 days and antibiotics‡ Control Further bleeding (~85% of cases) (~15% of cases) Consider early TIPS in high risk patients Rescue with TIPS *History, physical and blood exam, cultures; †Somatostatin/terlipressin; ‡Ceftriaxone (1 g/24 hours) is the first choice in patients with DC, those already on quinolone prophylaxis, and in hospital settings with high prevalence of quinolone-resistant bacterial infections. Oral quinolones (norfloxacin 400 mg BID) should be used in the remaining patients (I; 1) Figure adapted from de Franchis R, et al. J Hepatol 2015; 63: 743 52; EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Acute variceal haemorrhage: treatment • Vasoactive drugs and ligation are the primary options for acute VH – There may be a role for TIPS in selected high-risk patients Recommendation Grade of evidence Grade of recommendation The combination of vasoactive drugs and ligation is recommended as the first therapeutic option in acute variceal bleeding I 1 Early pre-emptive covered TIPS (placed within 24– 72 hours) can be suggested in selected high-risk patients, such as those with Child–Pugh class C with score <14 • However, the criteria for high-risk patients, particularly Child–Pugh B with active bleeding, remains debatable and needs further study I 2 EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Management of persistent bleeding • Up to 10– 15% of patients have persistent bleeding or early re-bleeding – Despite treatment with vasoactive drugs and EBL, and prophylactic antibiotics Recommendation Grade of evidence Grade of recommendation TIPS should be used as the rescue therapy of choice in cases of persistent bleeding or early re-bleeding I 1 III 1 I 2 In the context of bleeding, where encephalopathy is commonly encountered, prophylactic lactulose may be used to prevent encephalopathy, but further studies are needed I 2 β-blockers and vasodilators should be avoided during the acute bleeding episode III 1 With the pre-requisite of expertise, balloon tamponade should be used in case of uncontrolled bleeding as a temporary ‘‘bridge” (max 24 hours) until definitive treatment can be instituted • Removable, covered and self-expanding oesophageal stents can be used as an alternative to balloon tamponade EASL CPG decompensated cirrhosis. J Hepatol 2018; doi: 10. 1016/j. jhep. 2018. 03. 024

Bacterial infections • Risk of bacterial infection in patients with cirrhosis is caused by multiple factors – – – • Liver dysfunction Portosystemic shunting Gut dysbiosis Increased BT Cirrhosis-associated immune dysfunction Genetic factors Spontaneous bacterial peritonitis – Definition: bacterial infection of ascitic fluid without any intra-abdominal surgically treatable source of infection – Prevalence: all patients with cirrhosis and ascites are at risk • 1. 5– 3. 5% in outpatients; 10% in hospitalized patients – Prognosis: mortality exceeded 90% when first described • Reduced to ~20% with early diagnosis and treatment EASL CPG decompensated cirrhosis.

Hg should be considered an absolute contraindication to LT irrespective of therapy applied II-2 1 III 1 Therapy to lower m. PAP and improve right ventricular function should be commenced in patients with m. PAP ≥ 35 mm. Hg • Right ventricular function should be periodically evaluated II-2 1 MELD exception can be considered in patients with proven PPHT in whom targeted therapy fails to decrease m. PAP <35 mm. Hg but does facilitate normalization of PVR to <240 dyn. s/cm-5 and right ventricular function II-3 2 MELD exception should be advocated in patients with proven PPHT of moderate severity (m.
