This study aims to evaluate the prognostic significance of the AKI criteria in cirrhotic patients hospitalized for acute decompensation. This is a prospective cohort study. AKI was defined as an increase in creatinine (Cr) levels ≥ 0.3 mg/dL in 48 h or ≥ 50% of the basal value in the last 7d. AKI was divided into stages 1 (elevation: < 2x basal), 2 (2 or 3x), and 3 (> 3x). In this study, 227 patients aged 53.9 ± 11.5 years were included, of whom 37% had AKI (28% AKI1, 5% AKI2, and 4% AKI3). Thirty percent of the patients died or were transplanted within 90 days from causes related to the presence of ascites at hospital admission and higher values of Chronic Liver Failure-Sequential Organ Failure Assessment (CLIF-SOFA) scores, but not to the presence of AKI. In a regression analysis conducted to assess the effect of the final Cr level in patients with AKI, 90-...

Early diagnosis and treatment of syphilis are essential to reduce morbidity and prevent transmission. The availability of rapid tests (RTs) for this diagnosis means that testing can be performed more quickly, as a point-of-care test, even in non-laboratory environments and requires only simple technical training to antibodies detection. The objective of this study was to evaluate the performance and operational aspects of seven commercially available RTs for syphilis in Brazil. Seven rapid treponemal tests were evaluated for sensitivity, specificity, accuracy and Kappa value, according to a panel composed of 493 members. The operational performance of the assay was also determined for these tests. The seven RTs showed sensitivity ranging from 94.5% to 100% when compared with the reference tests and specificity of between 91.5% and 100%. All the RTs evaluated p...

We aimed to study PTX3 levels in patients with liver cirrhosis. A prospective cohort study included 130 patients hospitalized for acute decompensation of liver cirrhosis, 29 stable cirrhotic outpatients and 32 healthy controls evaluated in a tertiary hospital in Southern Brasil. The median PTX3 level was significantly higher in stable cirrhotic patients compared to controls (2.6 vs. 1.1 ng/mL; p < 0.001), hospitalized cirrhotic patients compared to controls (3.8 vs. 1.1 ng/mL; p < 0.001), and hospitalized cirrhotic patients compared to stable cirrhotic patients (3.8 vs. 2.6 ng/mL; p = 0.001). A positive correlation was found between PTX3 and serum creatinine (r = 0.220; p = 0.012), Chronic Liver Failure - Sequential Organ Failure Assessment score (CLIF-SOFA) (r = 0.220; p = 0.010), MELD (r = 0.279; p = 0.001) and...

Our aim was to evaluate the prognostic significance of circulating cytokines interleukin (IL)-6, IL-17 and IL-10 in different stages of cirrhosis. 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. 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 disea...

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 Chronic Liver Failure (CLIF)-Sequential Organ Failure Assessment (SOFA) Score recently proposed by the EASL-CLIF Consortium in a cohort of patients admitted for acute decompensation (AD) of cirrhosis. Methods: The diagnosis of cirrhosis was established either histologically (when available) or by the combination of clinical, imaging, and laboratory findings in patients with evidence of portal hypertension. Patients were clinically assessed within 24 hours of admission and at days 3, 7, 30 and 90 post enrollment. All subjects underwent laboratory evaluation at admission. The CLIF-SOFA score and the ACLF criteria were applied according to the EASL-CLIF Consortium definition. R...

However, data about its prognostic significance is still lacking. We sought to investigate the relationship between serum IGF-1 levels and short-term prognosis in patients admitted for acute decompensation of cirrhosis. Methods: In this prospective cohort study, patients admitted in the emergency department were followed during their hospital stay and 90-day mortality was evaluated by phone call, in case of hospital discharge. All subjects underwent laboratory evaluation at admission. The acute-on-chronic liver failure (ACLF) criteria were applied according to the EASL-CLIF Consortium definition. Twenty-one patients were also evaluated in the outpatient clinic after discharge and were compared in two moments (inpatient and outpatient evaluation). Results: Between December 2011 and November 2013, 103 patients were included, with a mean age...
