Objective: To investigate the prognostic significance of thyroid hormone profile in patients hospitalized for decompensated cirrhosis., Subjects and Methods: Prospective cohort study that included 119 subjects. All subjects were evaluated at admission and followed for 90 days. TSH, fT3, fT4 were measured within 24 hours of hospitalization., Results: Higher fT4 and lower fT3 levels were observed among Child-Pugh C patients as compared to Child-Pugh A and B, and in those with acute-on-chronic liver failure (ACLF). Lower fT3/fT4 ratio was observed in those with ascites, infections, ACLF, and in Child-Pugh C. Ninety-day mortality was 26.9% and it was independently associated with higher Model for End-stage Liver Disease (MELD) and TSH, and lower fT3/fT4 ratio in multivariate analysis. A new prognostic model including MELD, TSH and fT3/fT4 ratio was devised. The areas under the receiver operating characteristic curves for MELD, fT3/fT4 ratio, TSH (μIU/mL), and the new model for predicting 90-day mortality were 0.847 ± 0.041, 0.841 ± 0.039, 0.658 ± 0.062, and 0.899 ± 0.031, respectively. The 90-day survival was 31.6% in patients with values of the predictive model ≥ -0.77 and 93.5% for values < -0.77 (P < 0.001)., Conclusions: Thyroid hormone profile was strongly associated with worse outcomes in patients with cirrhosis and might represent promising prognostic tools that can be incorporated in clinical practice., Competing Interests: Disclosure: no potential conflict of interest relevant to this article was reported.

Introduction and Aim: Hepatic encephalopathy (HE) is a frequent complication of cirrhosis, but the clinical and prognostic significance of the progression of mental status in hospitalised cirrhotics is unknown. We aimed to investigate the prognostic significance of serial evaluation of HE in patients hospitalised for acute decompensation (AD) of cirrhosis., Materials and Methods: Patients (n=293) were evaluated for HE (West-Haven criteria) at admission and at day-3 and classified in two groups: (1) Absent or improved HE: HE absent at admission and at day-3, or any improvement at day-3; (2) Unfavourable progression: Development of HE or HE present at admission and stable/worse at day-3., Results: Unfavourable progression of HE was observed in 31% of patients and it was independently associated with previous HE, Child-Pugh C and acute-on-chronic liver failure (ACLF). MELD score and unfavourable progression of HE were independently associated with 90-day mortality. The 90-day Kaplan-Meier survival probability was 91% in patients with MELD<18 and absent or improved HE and only 31% in subjects with both MELD≥18 and unfavourable progression of HE. Unfavourable progression of HE was also related to lower survival in patients with or without ACLF. Worsening of GCS at day-3 was observed in 11% of the sample and was related with significantly high mortality (69% vs. 27%, P<0.001)., Conclusion: Among cirrhotics hospitalised for AD, unfavourable progression of HE was associated with high short-term mortality and therefore can be used for prognostication and to individualise clinical care., (Copyright © 2019 Fundación Clínica Médica Sur, A.C.

Background & Aims: An algorithm including Sepsis-3 criteria and quick Sequential Organ Failure Assessment (qSOFA) was recently proposed to predict severity of infection in cirrhosis. However, its applicability among patients without a baseline SOFA available for Sepsis-3 definition is unknown. We sought to investigate the applicability and prognostic value of qSOFA and Sepsis-3 criteria in patients with cirrhosis hospitalised for bacterial infections, without pre-hospitalisation SOFA., Methods: In this cohort study, 164 patients were followed up to 30 days. Data collection, including the prognostic models, was performed at admission and at day-3., Results: All patients fulfilled Sepsis-3 criteria (admission SOFA ≥ 2) and, therefore, admission Sepsis-3 was not included in further analysis. Admission qSOFA was an independent predictor of survival (HR = 2.271, P = 0.015). For patients initially classified as high risk by qSOFA, Chronic Liver Failure - Sequential Organ Failure Assessment (CLIF-SOFA) was the only prognostic predictor. Among patients initially classified as low risk by qSOFA, the following parameters evaluated at day-3 were independent predictors of survival: qSOFA, acute-on-chronic liver failure, and Child-Pugh classification. Although not independently related to survival, Sepsis-3 criteria at day-3 was associated with lower 30-day survival in Kaplan-Meier analysis (66% vs 85%, P = 0.008). However, prognosis was better predicted by day-3 qSOFA, with 30-day Kaplan-Meier survival probability of 88% when qSOFA < 2 and 24% among those with qSOFA ≥ 2., Conclusion: Sepsis-3 criteria evaluated at admission are very limited in infected patients with cirrhosis without baseline SOFA. qSOFA was independently related to survival and appears to be a valuable tool for determining severity of infection and to follow patients initially classified as low risk., (© 2018 John Wiley & Sons A/S.

Introduction: Adiponectin and resistin levels are increased in patients with cirrhosis, but it prognostic significance is unknown. We sought to investigate the factors associated with adiponectin and resistin levels and its clinical significance in patients with cirrhosis., Materials and Methods: This was a prospective cohort study that included 122 subjects with cirrhosis who attended an outpatient clinic and were initially evaluated in 2012. Serum adiponectin and resistin levels were measured in samples collected in 2012 (adiponectin and resistin) and 2014 (adiponectin). Thirty healthy subjects served as a control group., Results: Higher adiponectin (21.59 μ g/mL vs. 12.52 μg/mL, P &lt; 0.001) and resistin levels (3.83 ng/mL vs. 2.66 ng/mL, P &lt; 0.001) were observed among patients with cirrhosis compared to controls. Patients classified as Child-Pugh B/C had higher adiponectin levels in relation to Child-Pugh A patients. At second measurement, adiponectin levels increased significantly in non-transplant patients and decreased in liver transplant recipients. Univariate Cox analysis showed that among patients with alcoholic liver disease, adiponectin levels were associated with lower transplant-free survival (HR = 1.034, 95% CI 1.006 - 1.062, P = 0.016). The transplant-free survival was significantly lower among patients with alcoholic liver disease and adiponectin ≥ 17 μg/mL (26.55 months, 95% CI 21.40-31.70) as compared to those with levels &lt; 17 μg/mL (33.76 months, 95% CI 30.70-36.82) (P = 0.045). No relationship was found between the levels of resistin and survival., Conclusion: Adiponectin but not resistin levels were associated with intensity of liver dysfunction and worse prognosis in patients with alcoholic liver disease, suggesting a potential as a prognostic biomarker.

Context: IGF-I serum levels are suppressed in cirrhosis, but its prognostic significance is unknown., Objectives: To investigate the prognostic value of IGF-I in patients admitted for acute decompensation of cirrhosis., Materials and Methods: Cohort study that included 103 patients. IGF-I was measured by enzyme-linked immunosorbent assay (ELISA)., Results: Ninety-day mortality was 26.2% and it was independently associated with MELD, age and IGF-I. The Kaplan-Meier survival probability at 90 days was 94.3% in patients with IGF-I ≥13 ng/mL and 63.2% for patients with IGF-I <13 ng/mL (p = .001)., Discussion and Conclusion: IGF-I levels are independently associated with mortality in acute decompensation of cirrhosis.

Introduction: Although both pro- and anti-inflammatory circulating cytokines are known to be elevated in liver cirrhosis, its clinical significance is not completely recognized. Our aim was to evaluate the prognostic significance of circulating cytokines interleukin (IL)-6, IL-17 and IL-10 in different stages of cirrhosis., Methods: This prospective study included two cohorts: (1) stable cirrhosis attended in the Outpatient Clinic (n=118), and (2) subjects hospitalized for acute decompensation (AD) (n=130). Thirty healthy subjects served as control group., Results: Patients with cirrhosis exhibited higher levels of cytokines as compared to controls. In stable cirrhosis, during a median follow-up of 17months, liver-related events occurred in 26 patients. Higher IL-10 levels and Child-Pugh B/C were independently associated with reduced event-free survival. In AD cohort, death after 90days of follow-up occurred in 39 patients and was independently associated with ascites, higher IL-6 and model for end-stage liver disease. IL-6 levels also showed higher AUROC than CRP for predicting bacterial infection in the AD cohort (0.831±0.043vs. 0.763±0.048, respectively). IL-17 decreased at third day of hospitalization only in patients who progressed to death. Higher IL-6 levels were observed in acute-on-chronic liver failure (ACLF) patients even in the absence of bacterial infection whereas IL-10 was higher only in subjects with infection-related ACLF. Higher IL-10 and IL-17 levels were associated with progression to death in ACLF., Conclusions: The pattern of immune response seems to vary according to the phase of cirrhosis and is related to prognosis, from stable disease to ACLF., (Copyright © 2017 Elsevier Ltd.

Aim: To investigate the prognostic significance of insulin-like growth factor-binding protein 3 (IGFBP-3) in patients with cirrhosis., Methods: Prospective study that included two cohorts: outpatients with stable cirrhosis (n = 138) and patients hospitalized for acute decompensation (n = 189). Development of complications, mortality or liver transplantation was assessed by periodical phone calls and during outpatient visits. The cohort of stable cirrhosis also underwent clinical and laboratory evaluation yearly (2013 and 2014) in predefined study visits. In patients with stable cirrhosis, IGFBP-3 levels were measured at baseline (2012) and at second re-evaluation (2014). In hospitalized subjects, IGFBP-3 levels were measured in serum samples collected in the first and in the third day after admission and stored at -80 °C. IGFBP-3 levels were measured by immunochemiluminescence., Results: IGFBP-3 levels were lower in hospitalized patients as compared to outpatients (0.94 mcg/mL vs 1.69 mcg/mL, P < 0.001) and increased after liver transplantation (3.81 mcg/mL vs 1.33 mcg/mL, P = 0.008). During the follow-up of the stable cohort, 17 patients died and 11 received liver transplantation. Bivariate analysis showed that death or transplant was associated with lower IGFBP-3 levels (1.44 mcg/mL vs 1.74 mcg/mL, P = 0.027). The Kaplan-Meier transplant-free survival probability was 88.6% in patients with IGFBP-3 ≥ 1.67 mcg/mL and 72.1% for those with IGFBP3 < 1.67 mcg/mL (P = 0.015). In the hospitalized cohort, 30-d mortality was 24.3% and was independently associated with creatinine, INR, SpO2/FiO2 ratio and IGFBP-3 levels in the logistic regression. The 90-d transplant-free survival probability was 80.4% in patients with IGFBP-3 ≥ 0.86 mcg/mL and 56.1% for those with IGFBP3 < 0.86 mcg/mL (P < 0.001)., Conclusion: Lower IGFBP-3 levels were associated with worse outcomes in patients with cirrhosis, and might represent a promising prognostic tool that can be incorporated in clinical practice.

Background & Aims: The idea of acute-on-chronic liver failure (ACLF) has emerged to identify those subjects with organ failure and high mortality rates. However, the absence of a precise definition has limited the clinical application and research related to the ACLF concept. We sought to validate the ACLF definition and the CLIF-SOFA Score recently proposed by the EASL-CLIF Consortium in a cohort of patients admitted for acute decompensation (AD) of cirrhosis., Methods: In this prospective cohort study, patients were followed during their hospital stay and thirty and 90-day mortality was evaluated by phone call, in case of hospital discharge. All subjects underwent laboratory evaluation at admission., Results: Between December 2010 and November 2013, 192 cirrhotic patients were included. At enrollment, 46 patients (24%) met the criteria for ACLF (Grades 1, 2 and 3 in 18%, 4% and 2% respectively). The 30-day mortality was 65% in ACLF group and 12% in the remaining subjects (P < 0.001). Logistic regression analysis showed that 30-day mortality was independently associated with ascites and ACLF at admission. The Kaplan-Meier survival probability at 90-day was 92% in patients without ascites or ACLF and only 22% for patients with both ascites and ACLF. The AUROC of CLIF-SOFA in predicting 30-day mortality was 0.847 ± 0.034, with sensitivity of 64%, specificity of 90% and positive likelihood ratio of 6.61 for values ≥9., Conclusion: In our single-centre experience the CLIF-SOFA and the EASL-CLIF Consortium definition of ACLF proved to be strong predictors of short-term mortality in cirrhotic patients admitted for AD., (© 2014 John Wiley & Sons A/S.

Introduction: Autoantibodies are often produced during infection with chronic hepatitis C virus (HCV), but it remains controversial whether they influence the biochemical profile and histological features of this disease. Therefore, this current study sought to describe these autoantibodies and evaluate their impact on the clinical and histological presentation of hepatitis C., Methods: This cross-sectional analytical study assessed patients with HCV (RNA+) from October 2011 to July 2012., Results: This study included 66 patients, with a mean age of 53.2±10.5 years. Of these patients, 60.6% were male, and 54.3% presented with genotype 1. Non-organ-specific autoantibodies (NOSA) were detected in 24% of the patients; of these, 7.6% were anti-mitochondrial antibodies (AMA+), 26.7% were anti-smooth muscle antibodies (SMA+) and 6.8% were liver kidney microsomal type 1 antibodies (LKM1+). With respect to the thyroid autoantibodies, 7.4% were anti-peroxidase (ATPO+) antibodies, and none were anti-thyroglobulin (ATG+) antibodies. Regarding celiac disease autoantibodies, 5.8% were endomysial antibodies (EMA+), and no transglutaminase (TTG+) antibodies were detected. Cryoglobulins were found in 2.1% of patients. When NOSA+ individuals were compared to patients without the presence of NOSAs, they exhibited higher median alkaline phosphatase (0.7 vs. 0.6 xULN; p=0.041), lower median platelet counts (141,500.0 vs. 180,500.0/mm 3 ; p=0.036), lower mean prothrombin activity (72.6±11.5% vs. 82.2±16.0%; p=0.012) and an increased prevalence of significant fibrosis (E≥2) (45.5% vs. 18.2%; p=0.012). There was also a tendency for a greater proportion of NOSA+ cases to have marked periportal activity (APP≥3) (44.5% vs. 15.6%; p=0.087)., Conclusions: In addition to the high prevalence of autoantibodies associated with HCV infection, it was observed that NOSA positivity was associated with a more severe histological and biochemical profile of hepatitis C infection.

Introduction: Although it is standard procedure in the evaluation of liver diseases, biopsy is an invasive method subject to sampling error and intra or inter-observer variability. Thus, surrogate markers of liver fibrosis have been proposed, with variable availability and accuracy., Aim: Validate and compare the performance of APRI and FIB-4 as predictors of liver fibrosis in HCV patients., Material and Methods: Cross-sectional study including patients with HCV-RNA (+) who underwent liver biopsy. Significant fibrosis was defined as METAVIR stage ≥ 2. The diagnostic performance of the models in predicting significant fibrosis were evaluated and compared by ROC curves., Results: The study included 119 patients, mean age 43.7 ± 10.6 years and 62% males. Significant fibrosis was identified in 41 patients. The AUROCs observed were: APRI = 0.793 ± 0.047, FIB-4 = 0.811 ± 0.045 and AST/ALT = 0.661 ± 0.055 (P = 0.054 for APRI vs. AST/ALT, and P = 0.014 for FIB-4 vs. AST/ALT). Considering classic cutoffs, the PPV and NPV for APRI and FIB-4 were, respectively, 77% and 92% and 83% and 81%. Thirteen (19%) patients were misdiagnosed by APRI and 16 (18%) by FIB-4. By restricting the indication of liver biopsy to patients with intermediate values, it could have been correctly avoided in 47% and 63% of the patients with APRI and FIB-4, respectively., Conclusion: The models APRI and FIB-4 were superior to AST/ALT ratio in the diagnosis of significant fibrosis in chronic HCV infection. Even though the overall performance of APRI and FIB-4 was similar, a higher proportion of patients may be correctly classified by FIB-4.

Relapsing polychondritis is an immune-mediated disease associated with inflammation in cartilaginous structures and other tissues throughout the body, particularly the ears, nose, eyes, joints, and respiratory tract. Although association with other conditions is seen in about one-third of the cases, liver involvement is not usually observed in those patients. We described a case of liver involvement in relapsing polychondritis, presenting with a predominantly cholestatic pattern. Other conditions associated with abnormal liver tests were excluded and the patient showed a prompt response to steroid therapy. We discuss the spectrum of the liver involvement in relapsing and review the literature.
