RESUMO
BACKGROUND AND AIM: The prevalence of alcohol-associated cirrhosis is increasing. In this respect, we investigated the long-term impact of non-abstinence on the clinical course of alcohol-associated cirrhosis. METHODS: We retrospectively evaluated 440 patients with alcohol-associated cirrhosis (compensated cirrhosis: n â =â 190; decompensated cirrhosis: n â =â 250) diagnosed between January 2000 and July 2017 who consumed alcohol until diagnosis of cirrhosis. We assessed liver-related outcomes including first and further decompensating events (ascites, variceal bleeding, and hepatic encephalopathy), and death in relation to continued alcohol use. RESULTS: Overall, 53.6% of patients remained abstinent (compensated cirrhosis: 57.9%; decompensated cirrhosis: 50.4%). Non-abstinent versus abstinent patients with compensated cirrhosis and decompensated cirrhosis showed significantly higher 5-year probability of first decompensation (80.2% vs. 36.8%; P â <â 0.001) and further decompensation (87.9% vs. 20.6%; P â <â 0.001), respectively. Five-year survival was substantially lower among non-abstinent patients with compensated cirrhosis (45.9% vs. 90.7%; P â <â 0.001) and decompensated cirrhosis (22.9% vs. 73.8%; P â <â 0.001) compared to abstinent. Non-abstinent versus abstinent patients of the total cohort showed an exceedingly lower 5-year survival (32.2% vs. 82.4%; P â <â 0.001). Prolonged abstinence (≥2â years) was required to influence outcomes. Non-abstinence independently predicted mortality in the total cohort (hazard ratio [HR] 3.371; confidence interval [CI]: 2.388-4.882; P â <â 0.001) along with the Child-Pugh class (HR: 4.453; CI: 2.907-6.823; P â <â 0.001) and higher age (HR: 1.023; CI: 1.007-1.039; P â =â 0.005). CONCLUSION: Liver-related outcomes are worse among non-abstinent patients with alcohol- associated cirrhosis prompting urgent interventions ensuring abstinence.

Autoimmune hepatitis (AIH) is characterized by elevated serum transaminase, increased immunoglobulin G levels, presence of autoantibodies, and hepatocellular damage. Coexistence with other autoimmune diseases has been reported in almost half of patients with AIH. Here, we report a 60-year-old man who developed rapidly progressive, bilateral, asymmetrical, and asynchronous sensorineural hearing loss that was consistent with immune-mediated inner ear disease (IMIED). This devastating presentation evolved as a late manifestation in the context of a six-month systemic illness that had previously resulted in type 1 AIH. A biochemical remission with normalization of aminotransferases achieved within two months after the initiation of corticosteroids with azathioprine. Further, an acceptable response has also been achieved at the patient regarding the right ear-hearing impairment; though, treatment could not reverse the substantial decrement in hearing capability of the left ear. To our knowledge, this is the first case report of the concurrent development of type 1 AIH and IMIED.
RESUMO
BACKGROUND AND AIMS: The definition of relative adrenal insufficiency (RAI) in patients with cirrhosis remains controversial. We investigated the serum and salivary cortisol (SalC) response after low-dose and standard-dose Synacthen test in patients with stable cirrhosis and ascites. METHODS: Ninety-five cirrhotic patients with ascites were prospectively evaluated from January 2014 to January 2018. Low-dose [adrenocorticotrophic hormone (ACTH): 1 µg] and standard-dose (ACTH: 250 µg) Synacthen test were successively performed. Paired serum total and saliva cortisol were taken at baseline, 30 min (low-dose test) and 60 min (standard-dose test). Salivary and Δserum total cortisol criteria included post-ACTH SalC < 12.7 ng/ml and/or SalC increase <3 ng/ml and serum total cortisol increase <9 µg/dl, respectively. RESULTS: The prevalence of RAI varied according to the definition used. SalC-defined RAI was significantly more common after low-dose than standard-dose test (54.7% vs. 20%; P < 0.001). Δserum total cortisol-defined RAI was also significantly more frequent after low-dose than standard-dose test (66.3% vs. 24.2%; P < 0.001). Considering low-dose test/SalC criteria as reference diagnostic criteria, standard-dose/salivary and Δserum total cortisol criteria showed low specificity for RAI diagnosis (43.9% and 52.7%, respectively). Survival probability was significantly lower in patients with low-dose test/SalC-defined RAI compared to those without (53.8% vs. 79.1%; P = 0.01). SalC-defined RAI after low-dose test was significantly more common than that defined after standard-dose test (72.7% vs. 30.3%; P < 0.001) among patients who died. CONCLUSION: Low-dose test/SalC definition can identify RAI in about half of patients with stable cirrhosis and ascites and is associated with increased mortality.

BACKGROUND: No evidence is available on the natural history of grade 1 ascites and its progression to grade 2/3 in patients with liver cirrhosis. The aim of the current study was to address this issue, to assess the development of main comorbid disorders closely related to ascites progression, and to identify the predictive factors for survival in this setting. METHODS: Consecutive Caucasian cirrhotic patients with grade 1 ascites were retrospectively analyzed. None of patients was under treatment with diuretics at diagnosis. Control groups consisted of 145 cirrhotics with grade 2/3 ascites and 175 cirrhotics without ascites. RESULTS: Diuretics were initiated in 58 patients with grade 1 ascites at baseline by the attending physician. At the last follow up, 29 patients had no ascites, 33 patients had grade 1 and 38 patients had grade 2/3 ascites. No variable was found to be an independent predictor of grade 2/3 ascites. Seven patients developed spontaneous bacterial peritonitis while under treatment with diuretics; at that time only 1 patient had grade 1 ascites. The mortality rate was similar among all examined groups. CONCLUSIONS: This study suggests that the presence of grade 1 ascites does not constitute a precursor of grade 2/3 ascites in patients with cirrhosis. Thus, patients with grade 1 ascites do not require specific treatment with diuretics.

BACKGROUND: In recent years, concerns have been raised on the potential adverse effects of nonselective beta-blockers, and particularly carvedilol, on renal perfusion and survival in decompensated cirrhosis with ascites. We investigated the long-term impact of converting propranolol to carvedilol on systemic hemodynamics and renal function, and on the outcome of patients with stable cirrhosis and grade II/III nonrefractory ascites. PATIENTS AND METHODS: Ninety-six patients treated with propranolol for esophageal varices' bleeding prophylaxis were prospectively evaluated. These patients were randomized in a 2:1 ratio to switch to carvedilol at 12.5 mg/d (CARVE group; n=64) or continue propranolol (PROPRA group; n=32). Systemic vascular resistance, vasoactive factors, glomerular filtration rate, and renal blood flow were evaluated at baseline before switching to carvedilol and after 6 and 12 months. Further decompensation and survival were evaluated at 2 years. RESULTS: During a 12-month follow-up, carvedilol induced an ongoing improvement of systemic vascular resistance (1372±34 vs. 1254±33 dynes/c/cm5; P=0.02) along with significant decreases in plasma renin activity (4.05±0.66 vs. 6.57±0.98 ng/mL/h; P=0.01) and serum noradrenaline (76.7±8.2 vs. 101.9±10.5 pg/mL; P=0.03) and significant improvement of glomerular filtration rate (87.3±2.7 vs. 78.7±2.3 mL/min; P=0.03) and renal blood flow (703±17 vs. 631±12 mL/min; P=0.03); no significant effects were noted in the PROPRA group. The 2-year occurrence of further decompensation was significantly lower in the CARVE group than in the PROPRA group (10.5% vs. 35.9%; P=0.003); survival at 2 years was significantly higher in the CARVE group (86% vs. 64.1%; P=0.01, respectively). CONCLUSION: Carvedilol at the dose of 12.5 mg/d should be the nonselective beta-blocker treatment of choice in patients with cirrhosis and nonrefractory ascites, as it improves renal perfusion and outcome.

BACKGROUND: The aim of this study was to predict the occurrence of hepatorenal syndrome (HRS) and death in patients with advanced cirrhosis and ascites. PATIENTS AND METHODS: We retrospectively evaluated 2-year data of 78 patients with cirrhosis and ascites (Child-Pugh B/C: 45/43). The mean arterial pressure (MAP) and cardiac output (CO) were measured in all patients just before administration of 2 mg of terlipressin and 30 min later. Systemic vascular resistance (SVR) was calculated as MAP/CO. ΔMAP, and ΔCO, and ΔSVR were defined as the percentage change of MAP, CO, and SVR, respectively, after terlipressin injection. Plasma renin activity (PRA) and plasma aldosterone were evaluated at baseline. Two multivariate models were used: one excluding (model 1) and one including (model 2) the Model of End-stage Liver Disease score. RESULTS: Higher ΔSVR, Model of End-stage Liver Disease score, and PRA were related independently to the severity of cirrhosis. Independent predictors of HRS at 12 and 24 months were ΔSVR (models 1/2: P=0.008/0.01 and 0.01/0.02, respectively), ΔCO (models 1/2: P=0.01/0.03 and 0.03/0.04, respectively), and PRA (models 1/2: P=0.04 and model 1: P=0.04, respectively). ΔSVR at 12 and 24 months (models 1/2: P=0.005/0.01 and 0.01/0.03, respectively) and ΔCO at 24 months (models 1/2: P=0.02/0.01, respectively) were related independently to survival. Patient groups with significantly higher probability of HRS and mortality were identified by certain cutoffs of ΔSVR (20.6 and 22.8%, respectively) and ΔCO (-10.6 and -11.8%, respectively). ΔSVR and ΔCO independently predicted survival in patients with the most advanced cirrhosis and infection-related survival. CONCLUSION: An increase in SVR by at least 20% and a decrease in CO at least 10% in response to terlipressin could predict HRS and mortality in patients with advanced cirrhosis.

BACKGROUND & AIMS: Several lines of evidence suggest that the hemostatic disorders of cirrhosis may have a significant clinical impact. We investigated the independent predictive value of components of the hemostatic system on the occurrence of ascites, variceal bleeding (VB), and survival. METHODS: One hundred and two patients with thrombocytopenia (Child-Pugh class A/B/C: 34/34/34) were enrolled. Platelet counts, factors (F) II, V, VII, and VIII, antithrombin, protein C (PC), FVIII-to-PC ratio as an index of procoagulant imbalance, von Willebrand factor antigen (vWF-Ag), and model for end-stage liver disease (MELD) were evaluated. Two multivariate analyses were performed: one excluding (model 1) and one including MELD (model 2). RESULTS: Higher vWF-Ag levels and FVIII-to-PC ratios were the most prominent hemostatic disorders in patients with cirrhosis. Increased levels of vWF-Ag and FVIII, and higher FVIII-to-PC ratios independently predicted the presence of ascites and varices at baseline. Independent predictors of ascites and VB during follow-up were vWF-Ag (model 1/2: p=0.001/p=0.009 and p=0.008/p=0.01, respectively) and FVIII-to-PC ratio (model 1/2: p=0.003/p=0.02 and p=0.01/p=0.03, respectively). vWF-Ag (model 1/2: p=0.007/p=0.002), FVIII-to-PC ratio (model 1/2: p=0.001/p=0.01), and MELD (p=0.02) independently predicted mortality. Patient groups with significantly higher probability of new-onset ascites, VB, and mortality were identified by certain cut-offs of vWF-Ag (213%, 466%, and 321%, respectively) and FVIII-to-PC ratio (1.99, 3.29, and 2.36, respectively). vWF-Ag and FVIII-to-PC ratio equaled MELD in mortality prediction. CONCLUSIONS: Advanced cirrhosis is characterized by increased thrombotic potential. vWF-Ag and FVIII-to-PC ratio independently predict new-onset ascites, VB, and mortality. Targeting hypercoagulability could improve the outcome of patients with cirrhosis. LAY SUMMARY: Higher von Willebrand factor antigen (vWF-Ag) levels and factor VIII-to-protein C (FVIII-to-PC) ratio are the prominent hemostatic disorders in patients with cirrhosis. vWF-Ag and FVIII-to-PC ratio independently predict new-onset ascites, variceal bleeding, and mortality in these patients.

Increased thrombotic potential within the liver sinusoids due to local endothelial production of von Willebrand factor antigen macromolecules could represent an additional therapeutic target of portal hypertension in patients with cirrhosis. In this case, anti-inflammatory and antithrombotic drugs could modulate portal pressure by preventing the formation of intrahepatic platelet-induced microthrombi.

AIM: Hypercoagulability has been detected in patients with cirrhosis yet its clinical significance remains unclear. We investigated the association of hypercoagulability with clinical outcomes in patients with cirrhosis. METHODS: Thrombin-antithrombin (TAT) complexes as thrombin generation (TG) marker, D-dimer, antithrombin (AT), protein C, protein S, international normalized ratio (INR), activated partial thromboplastin time, fibrinogen, Child-Pugh class and Model for End-Stage Liver Disease (MELD) were evaluated. Two different multivariate analyses were performed: one not including MELD (model 1) and one including MELD and excluding INR (model 2). RESULTS: Eighty-one patients (Child-Pugh class A/B/C: 27/27/27) and 40 healthy subjects were enrolled. Only ΤΑΤ and AT were independently associated with increasing liver disease severity. Increased TAT levels and MELD score were significantly associated with ascites and varices at baseline. Independent predictors of follow-up events were: TAT and MELD score for new-onset ascites; TAT and AT for variceal bleeding (VB); TAT and AT for portal vein thrombosis (PVT); and TAT and MELD for mortality. TAT equaled MELD in mortality prediction at 12 and 18 months. TAT cut-offs at 5.35, 14.6, 13.5 and 9.25 ng/mL identified patient groups with significantly higher probability of new-onset ascites, VB, PVT and mortality, respectively. CONCLUSION: Increased TG is strongly correlated with portal hypertension-related complications, PVT and mortality in patients with cirrhosis. Measuring TG by TAT could enable risk stratification and institution of preventive strategies to improve clinical outcomes.
RESUMO
According to a review article by Biecker et al published in a previous issue of World Journal of Gastroenterology in March 2011, intestinal decontamination with norfloxacin remains the mainstay of primary prophylaxis of spontaneous bacterial peritonitis (SBP) at the expense of development of quinolone-resistant bacteria after long-term use. In our research, the administration of a 4-wk regimen with rifaximin 1200 mg/d reduced significantly the ascitic neutrophil count in cirrhotic patients with sterile ascites in line with a significant decrease in plasma endotoxin levels. Our observations concur with recent findings, showing a significantly reduced 5-year probability of SBP in cirrhotic patients taking rifaximin.

Circulating levels of endotoxin, interleukin (IL)-6, and tumor necrosis factor (TNF)-α increase with intestinal bacterial overgrowth and translocation, and are believed to be involved in the pathogenesis of hyperdynamic circulatory syndrome and functional renal failure in patients with advanced cirrhosis. We investigated the effects of the antibiotic rifaximin on systemic hemodynamics and renal function in patients with alcohol-related cirrhosis and ascites. We measured mean arterial pressure, cardiac output (CO) by Doppler ultrasound, systemic vascular resistance (as the ratio of mean arterial pressure:CO), plasma renin activity, levels of plasma aldosterone, the glomerular filtration rate by plasma clearance of technetium-99m-DTPA, natriuresis, levels of plasma endotoxin, and serum levels of IL-6 and TNF-α in 13 patients at baseline and after 4 weeks of treatment with rifaximin. Rifaximin treatment significantly reduced CO and significantly increased systemic vascular resistance, in association with a significant decrease in plasma rennin activity. The therapy also significantly increased the glomerular filtration rate and natriuresis while reducing levels of endotoxin, IL-6, and TNF-α. Intestinal decontamination with rifaximin improved systemic hemodynamics and renal function in patients with advanced cirrhosis.

PURPOSE: Endotoxin and interleukin-6 levels (IL-6) have been involved in the development of pulmonary hypertension (PH) in non-cirrhotic experimental models and subjects. High circulating levels of both substances have been detected in cirrhosis. The association between circulating endotoxin and IL-6 levels and echocardiographically evaluated pulmonary vascular resistance (PVR) in cirrhotic patients are investigated. METHODS: Thirty-seven cirrhotic patients were studied: 25 with PVR <120 dynes s cm(-5) (group 1) and 12 with PVR >120 dynes s cm(-5) (group 2). Plasma endotoxin and serum IL-6 levels were measured. The PVR and cardiac output (CO) by Doppler ultrasound, mean arterial pressure (MAP), and systemic vascular resistance (SVR) as the ratio MAP/CO were evaluated. RESULTS: Child-Pugh scores, MAP, CO, and SVR were similar in both groups. Endotoxin levels were correlated significantly with IL-6 levels (r = 0.342; P = 0.03). Endotoxin and IL-6 levels were significantly higher in group 2 compared to group 1 (2.26 [0.39-8.4] vs. 0.85 [0.37-7.6] EU/mL; P = 0.04 and 37.4 [7.85-106.5] vs. 8.36 [3.15-53.7] pg/mL; P < 0.001, respectively). The PVR was correlated significantly with endotoxin levels in group 2 (r = 0.587; P = 0.04) and with IL-6 levels in group 1 (r = 0.529; P = 0.01) and group 2 (r = 0.760; P = 0.004), respectively. CONCLUSIONS: Our results suggest that endotoxin and IL-6 may contribute to cirrhosis-associated PH. In this regard, modulation of these substances could improve pulmonary pressures in cirrhotic patients.
RESUMO
Terlipressin has been associated with pulmonary arterial vasodilation in patients with pulmonary hypertension (PH). We investigated the effects of terlipressin on pulmonary vascular resistance (PVR) in patients with cirrhosis without and with PH. Pulmonary vascular resistance and cardiac output (CO) by Doppler ultrasound, mean arterial pressure (MAP), and systemic vascular resistance (SVR) were evaluated in patients with cirrhosis with PVR -120 dyne s cmâ»5 (group 1, n = 20) and PVR >120 dyne s cmâ»5 (group 2, n = 10) before and 30 minutes after terlipressin infusion (2 mg). After terlipressin, PVR increased significantly in group 1 (96.1 ± 20.2 vs 85.1 ± 18 dyne s cmâ»5; P = .004) but decreased significantly in group 2 (170.4 ± 37.8 vs 157.8 ± 28.1 dyne s cmâ»5; P= .04). Pulmonary vascular resistance changes in group 2 correlated significantly with baseline PVR (r = -0.632; P = .04). Terlipressin induced a significant increase in MAP and SVR and a significant decrease in CO in both groups. Terlipressin significantly reduces pulmonary pressures in patients with cirrhosis having PH together with systemic hemodynamic improvement.
