Ultrasound (US) detection of liver nodules in cirrhotic patients requires further radiological examinations and often a follow-up with repeated short-term evaluations to verify the presence of hepatocellular carcinoma (HCC). Aims of the study were to assess the rate of HCC diagnosis and to identify HCC predictors in a cohort of cirrhotics followed-up after US detection of the liver nodule(s). One-hundred-eighty-eight consecutive cirrhotic patients (124 males, mean age 64.2 years) with liver nodule(s) detected by US were enrolled. All patients underwent second-level imaging [computed tomography (TC) or magnetic resonance (MR)], and those without a definite diagnosis of HCC were followed-up with TC and/or RM repeated every 3-6 months up to 18 months if HCC was not diagnosed. After 18 months, non-HCC patients came back to routine US surveillance. HCC was diagnosed in 73/188 cases (38.8%). In 66/73 patients (90.4%) HCC was identified at first radiological evaluation after US, while in the remaining seven subjects it was diagnosed at the subsequent imaging examination. Age (p = 0.001) and nodule dimension (p = 0.0001) were independent predictors of HCC at multivariate analysis. Fourty-nine/188 patients were lost at follow up after 18 months. Twenty/139 remaining patients developed HCC and 3/139 cholangiocarcinoma; 77 died between 3 and 110 months from the beginning of the study (61 for end-stage liver disease, 8 for extrahepatic causes, eight for unknown causes). Patients who developed liver cancer earlier during the follow up had the shortest overall survival. US-detected liver nodules are not neoplastic in more than half of cirrhotic patients. A definite diagnosis may be obtained at the time of the first radiologic evaluation after US in the vast majority of the cases. Patients in whom nodules are found not to be tumoral may return to the US surveillance program routinely applied to all cirrhotics.

Background: Data on erectile dysfunction (ED) in cirrhotic patients are limited as yet. Aim of this study was to investigate the prevalence of ED and the factors potentially involved in its development in compensated cirrhosis., Methods: We prospectively enrolled 102 male (mean age 63 ± 10 years) affected by cirrhosis in Child-Pugh Class A. The following questionnaires were used: simplified International Index of Erectile Function (IIEF-5) Questionnaire, Centre of Epidemiologic Studies Depression Scale and ANDROTEST., Results: ED was found in 57/102(55.9%) patients, and was mild, moderate and severe in 21(36.8%), 6(10.5%) and 30(52.6%) subjects, respectively. ED patients were significantly older than those without (66 ± 10 vs 60 ± 10,p = 0.006); ED prevalence gradually increased with age. There was no statistically significant difference between patients with and without ED concerning the coexistence of diabetes, hypertension, and cardiovascular disease. Age(p = 0.040) and serum haemoglobin(p = 0.027) were identified as predictors of ED on multivariate analysis. Liver-related factors and pharmacological treatment, including β-blockers, were not associated with the presence of ED., Conclusions: In patients with compensated liver cirrhosis, even in concomitance with other chronic comorbidities, the prevalence of ED is not markedly different from the general population. Compensated cirrhosis per se is not a risk factor for ED occurrence. Older age and low haemoglobin values are significantly associated with ED in cirrhotics., (Copyright © 2018 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Background & Aims: The outcome of compensated cirrhosis may vary considerably and cannot be predicted by routinely performed tests at present. The aim of this study was to evaluate possible predictors of clinical evolution in patients with Child-Pugh (C-P) class A cirrhosis because of untreatable causes by analysing clinical/biochemical/instrumental parameters evaluated at the time of diagnosis and during the subsequent long-lasting follow-up., Methods: Two hundred and seventy-two consecutive C-P class A cirrhotic patients (155 males; median age 63 years, range 34-81) were analysed. All patients were followed up for a median time of 96 months (range 21-144) through periodically performed clinical/biochemical/ultrasonographic and esophagogastroduodenoscopic examinations., Results: During the follow-up, 97 individuals (36%) were clinically stable, 104 (38%) developed hepatocellular carcinoma (HCC) and 71 (26%) progressed towards C-P class B/C without developing cancer. One hundred and thirty-one patients (48%) died or underwent liver transplantation. Multivariate regression analysis showed that clinical stability was significantly associated with older age (P < .001), the absence of diabetes (P = .04) and of oesophageal varices (P < .001), serum albumin >3.5 gr/dL (P = .01) and gamma globulin <1.8 gr/dL (P = .01). HCC development was significantly associated with younger age (P = .01) and serum gamma globulin values ≥1.8 gr/dL (P < .001). C-P score progression was associated with oesophageal varices (P < .001), lower serum albumin (P = .03) and cholesterol (P = .01) values, and hypergammaglobulinemia (P = .02). Death was associated with younger age (P < .001) and hypergammaglobulinemia (P = .01). Multivariate Cox regression analysis and Kaplan-Meier's survival test confirmed that gammaglobulinemia ≥1.8 g/dL was a significant predictor of death (P < .02, and P < .01 respectively)., Conclusions: Hypergammaglobulinemia identifies C-P class A cirrhotic patients at higher risk of disease progression, HCC development and death., (© 2017 John Wiley & Sons A/S.

Background: Patients with cirrhosis are at high risk of bacterial infections. Invasive procedures are generally believed to increase this susceptibility., Aims: We investigated the incidence of bacterial infections in cirrhotic patients undergoing elective endoscopic variceal ligation (EVL)., Methods: We enrolled 60 consecutive cirrhotic patients who underwent a total number of 112 elective EVL procedures. One to seven bands were applied at each session until variceal eradication. Markers of inflammation/infection and blood cultures were obtained before and 24 h after EVL., Results: Aetiology of liver disease was metabolic in 27 (45%), viral in 21 (35%), alcoholic in 12 (20%) patients. Child-Pugh class A/B/C distribution was 29/26/5, respectively, 23 (38%) patients had ascites and 15 (25%) had hepatocellular carcinoma. Blood cultures were negative in all samples before EVL, whereas 3/112 (2.7%) cultures tested positive after endoscopy. Streptococcus mitis and Staphylococcus epidermidis were isolated in 1 and 2 cases, respectively. None of these three patients developed any features of clinically relevant infection, suggesting that the positive cultures were an expression of a transient bacteraemia with no clinical sequelae., Conclusions: Bacterial infection is an uncommon occurrence after elective EVL in cirrhotic patients, and antibiotic prophylaxis is not necessary in this clinical setting., (Copyright © 2017 Editrice Gastroenterologica Italiana S.r.l.

Background & Aims: Serial evaluation of hepatitis B virus (HBV) DNA and aminotransferase values is required for identification of inactive HBV carriers (ICs). Recently, HBV surface antigen quantification (qHBsAg) and liver stiffness measurement (LSM) have been proposed as diagnostic tools in chronic HBV infection. The aim of this study was to evaluate the efficacy of HBV DNA quantification, qHBsAg and LSM in diagnosing ICs at a single time point., Methods: Fifty-seven previously characterized ICs and 90 untreated HBsAg-/anti-HBe-positive patients [49 chronic hepatitis (CH), 41 cirrhosis] were enrolled. HBV DNA ≤2000 IU/mL, LSM ≤6.2 kPa and qHBsAg ≤1000 IU/mL were used as cut-offs to evaluate sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy (DA)., Results: Combined HBV DNA quantification and qHBsAg correctly identified 30/57 (52.6%) ICs showing 94% sensitivity, 96% specificity, 98% PPV, 87% NPV and 95% DA. HBV DNA coupled with LSM identified 40/57 (70.2%) ICs showing 97% sensitivity, 97% specificity, 98% PPV, 95% NPV and 97% DA. Combined LSM and qHBsAg identified 33/57 (57.9%) ICs showing 95% sensitivity, 78% specificity, 89% PPV, 89% NPV and 89% DA. The evaluation of the three parameters altogether allowed the identification of 23/57 (40.3%) ICs showing 100% specificity, 96% sensitivity, 100% PPV, 92% NPV and 97% DA. Similar results were obtained when either CH or cirrhotic patients were excluded from the analysis., Conclusions: Combined evaluation of HBV DNA amount with LSM and/or qHBsAg is a highly reliable tool allowing the identification of a considerable number of HBV ICs at a single time point evaluation., (© 2016 John Wiley & Sons A/S.

Contrast medium administration is one of the leading causes of acute kidney injury (AKI) in different clinical settings. The aim of the study was to investigate occurrence and predisposing factors of AKI in cirrhotic patients undergoing contrast-enhanced computed tomography (CECT).Datasets of 1279 consecutively hospitalized cirrhotic patients were retrospectively analyzed. Two hundred forty-nine of 1279 patients (mean age 64 ± 11 years, 165 male) who had undergone CECT were selected on the basis of the availability of serum creatinine (sCr) values evaluated before and after CECT (CECT group). In analogy, 203/1279 cases (mean age 66 ± 10 years, 132 male) who had not undergone CECT and had been tested twice for sCr in 7 days were also included as controls (Control group). AKI network criteria were employed to assess contrast-induced AKI (CI-AKI) development. Apart from lack of narrowed double sCr measurements, additional exclusion criteria were active bacterial infections, nephrotoxic drugs intake, and estimated glomerular filtration rate <30 mL/min.AKI developed in 22/249 (8.8%) and in 6/203 (3%) of the CECT and the Control groups, respectively (P = 0.01). The multivariate logistic regression analysis showed that AKI was significantly associated with contrast medium administration (odds ratio [OR]: 3.242, 95% confidence interval [CI]: 1.255-8.375; P = 0.015), female sex (OR: 0.339, 95% CI: 0.139-0.827; P = 0.017), and sCr values (OR: 0.124, 95% CI: 0.016-0.975; P = 0.047). In the CECT group, presence of ascites (OR: 2.796, 95% CI: 1.109-7.052; P = 0.029), female sex (OR: 0.192, 95% CI: 0.073-0.510; P = 0.001), and hyperazotemia (OR: 1.018, 95% CI: 1.001-1.037; P = 0.043) correlated with CI-AKI development at multivariate analysis.CI-AKI is a quite frequent occurrence in cirrhotic patients with female sex, presence of ascites, and hyperazotemia being the predisposing factors., Competing Interests: The authors have no conflicts of interest to disclose.

Background & Aims: Few information is available regarding atrial fibrillation in cirrhotic patients. The aim of this study was to investigate the occurrence and clinical impact of atrial fibrillation in these patients., Methods: Three hundred and thirty-five cirrhotic patients (219 males; mean age 65 ± 10.85 years; 196 Child-Pugh class A, 104 class B and 35 class C) were consecutively analysed and followed up for 24 months. Electrocardiograms were available for all patients before starting the study, at basaltime and during the follow-up. Echocardiography was performed in individuals with atrial fibrillation and in 100 randomly chosen patients without it., Results: Atrial fibrillation was observed in 21/335 cirrhotics (mean age 75 ± 7 years, 13 male), six of whom had permanent and 15 had paroxysmal atrial fibrillation. At univariate analysis, atrial fibrillation significantly correlated with older age, history of coronary heart disease, Child-Pugh score, serum albumin, hepatic encephalopathy, treatment with furosemide, QTc prolongation, atrial section areas, increased PAPs and thickness of interventricular septum. Age [odd ratio 1.12, 95% CI (1.05-1.2), P = 0.001], history of coronary heart disease [odd ratio 4.93, 95% CI (1.04-23.54), P = 0.04] and PAPs [odd ratio 1.12, 95% CI (1.02-1.2), P = 0.01] maintained statistical significance at multivariate analysis. Fifty-one of the 335 patients died during the follow-up. At Cox regression analysis, advanced Child-Pugh score [hazard ratio 1.546, 95% CI (1.357-1.762), P = 0.037] and increased heart rate [hazard ratio 1.117, 95% CI (1.021-1.223), P = 0.016] were significantly associated with mortality which was independent of atrial fibrillation occurrence., Conclusions: Cirrhosis is not a predisposing factor of atrial fibrillation, which in turn has no impact on mortality in cirrhotic patients., (© 2015 John Wiley & Sons A/S.

The predictive factors of long-term clinical benefits in patients with hepatitis C virus (HCV)—related liver cirrhosis after Direct Antiviral Agents (DAA) treatment are still undefined. The aim of this study was to identify any predictors of liver failure, hepatocellular carcinoma (HCC) and/or death in patients with compensated liver cirrhosis who achieved the sustained virological response (SVR). To this purpose, 324 consecutive cirrhotic patients who started DAA treatment from 1 April 2015 to 31 December 2016 were retrospectively analyzed. All patients were followed up for a median time of 63 months (range 19–77) through clinical/biochemical/instrumental examinations performed at baseline and after stopping the DAA treatment. At the end of the evaluation, 230 (71%) individuals showed stable clinical liver disease over time, 43 (13.3%) developed HCC, and 24 (7.4%) developed hepatic decompensation without HCC. Overall, 49 (15,1%) patients died. Multivariate regression analysis showed that hepatic decompensation was significantly associated with at baseline older age, higher liver stiffness, higher spleen longitudinal size values and hypergammaglobulinemia (p = 0.003, p = 0.005, p = 0.001, p = 0.029, respectively). HCC development was significantly associated with hypergammaglobulinemia (p < 0.001). Death was associated with older age and hypergammaglobulinemia (p < 0.001 and p = 0.007, respectively). Finally, survival analysis confirmed that patients with gamma globulin levels ≥ 1.8 gr/dl had a significantly higher risk of death compared to those with gamma globulin levels < 1.8 gr/dl (p < 0.001). In conclusion, hypergammaglobulinemia before starting DAA therapy represents a strong predictor of hepatic decompensation, HCC and death in cirrhotic patients even after HCV clearance.
