RESUMEN
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.

BACKGROUND: Anastomotic leakage is the deadliest complication of colonic procedures. Ghrelin is an orexigenic hormone with potent actions on growth hormone release and functions in the processes of growth, tissue inflammation, repair, and oxidative stress. We evaluated the hypothesis that the exogenous administration of ghrelin causes beneficial effects on the healing of colonic anastomosis. MATERIALS AND METHODS: Sixty-four male Wistar rats were randomly assigned to eight subgroups receiving postoperative intraperitoneal administration of ghrelin (23 µg/kg/d) or saline after a colonic anastomosis. The anastomotic tissue was evaluated on the third, seventh, and 14th postoperative days. Anastomotic bursting pressure, histological parameters, hydroxyproline content, and tissue oxidative stress markers were compared. RESULTS: There was a significant increase in the mean anastomotic bursting pressure in the ghrelin subgroup on the seventh postoperative day (P = 0.035). Histological evaluation demonstrated a significant difference in the neutrophilic infiltrate (P = 0.035) on the third and 14th d and in apoptosis (P = 0.004), granulation tissue (P = 0.011) and peritoneal inflammation (P = 0.014) on the 14th postoperative day. There was a statistically significant increase in the hydroxyproline content in the ghrelin subgroup on the 14th postoperative day (P = 0.043). There were significant differences in the nitrite tissue levels (P = 0.021) on day 3 and in reactive oxygen species (P = 0.012) on day 14. CONCLUSIONS: The administration of ghrelin had beneficial anti-inflammatory and antioxidant effects, increasing the resistance of the anastomosis and the hydroxyproline tissue content in the postoperative period.

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.

In recent years, there has been increasing interest in finding new biomarkers for diagnosis and prognostication of liver diseases. MicroRNAs (miRNAs) are small noncoding RNA molecules involved in the regulation of gene expression and have been studied in relation to several conditions, including liver disease. Mature miRNAs can reach the bloodstream by passive release or by incorporation into lipoprotein complexes or microvesicles, and have stable and reproducible concentrations among individuals. In this review, we summarize studies involving circulating miRNAs sourced from the serum or plasma of patients with nontumoral liver diseases in attempt to bring insights in the use of miRNAs as biomarkers for diagnosis, as well as for prognosis of such diseases. In addition, we present pre-analytical aspects involving miRNA analysis and strategies for normalization of reverse transcription-quantitative polymerase chain reaction (RT-qPCR) data related to the studies evaluated.

MicroRNAs (miRNAs) have remarkable potential as diagnostic and prognostic markers because of their roles in disease pathogenesis. miRNAs can be released into the bloodstream, where they are sufficiently stable to be detected noninvasively. Here, we prospectively evaluated serum levels of miR-21, miR-34a, miR-122, miR-181b, and miR-885-5p in patients with stable cirrhosis. Total RNA was extracted from the sera of patients with cirrhosis and healthy individuals, and the expression levels of the target miRNAs were analyzed by reverse transcription-quantitative polymerase chain reaction. Serum miRNAs levels were correlated with liver function parameters, etiology, and complications of cirrhosis. Circulating miR-34a, miR-122, and miR-885-5p levels were higher in patients with cirrhosis than in healthy individuals. These miRNAs were positively correlated with alanine aminotransferase and aspartate aminotransferase levels, and the relative expression levels were higher in hepatitis C virus-infected patients and lower in patients with Child-Pugh C cirrhosis. miR-122 and miR-885-5p levels were also positively correlated with γ-glutamyl transpeptidase concentrations. miR-21 was associated with transplant-free survival in univariate Cox regression analysis and remained independently associated with survival after adjustment for age, Child-Pugh classification, Model for End-stage Liver Disease score, and history of previous decompensation in multivariate Cox regression analysis. These data suggested that miR-34a, miR-122, and miR-885-5p levels may be more related to the inflammatory process and ongoing hepatocyte damage in patients with cirrhosis. Moreover, miR-21 levels were independently associated with shorter transplant-free survival and may be used as a prognostic tool in outpatients with stable cirrhosis.

BACKGROUND: New criteria for acute kidney injury (AKI) in cirrhosis have been proposed, but its prognostic significance is unclear. This study aims to evaluate the prognostic significance of the AKI criteria in cirrhotic patients hospitalized for acute decompensation. MATERIAL AND METHODS: 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). RESULTS: 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-day mortality was associated with ascites, higher CLIF-SOFA score, and AKI with final Cr level ≥ 1.5 mg/dL. The patients with AKI with Cr levels ≥ 1.5 mg/dL showed lower transplant-free survival rates than those without AKI, and those with AKI1 with final Cr level < 1.5 mg/dL. CONCLUSIONS: Early AKI was frequent and associated with 90-day mortality or transplantation only when the final Cr level was ≥ 1.5 mg/dL. Distinct approaches are needed for patients with AKI1 according to final Cr.

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 < 0.001) and resistin levels (3.83 ng/mL vs. 2.66 ng/mL, P < 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 < 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.

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.

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.

BACKGROUND: Despite the circulating levels of PTX3 were related to the severity of various diseases, there are no studies investigating its role in patients with liver cirrhosis. We aimed to study PTX3 levels in patients with liver cirrhosis. MATERIAL AND METHODS: 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. RESULTS: 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 Child-Pugh score (r = 0.224; p = 0.010). Significantly higher levels of PTX3 were observed in patients on admission with ACLF (8.9 vs. 3.1 ng/mL; p < 0.001) and MELD score ≥ 20 (6.6 vs. 3.4 ng/mL; p = 0.002). Death within 90 days occurred in 30.8% of patients and was associated with higher levels of PTX3 (5.3 vs. 3.4 ng/mL; p = 0.009). The probability of Kaplan-Meier survival was 77.0% in patients with PTX-3 < 5.3 ng mL (upper tercile) and 53.5% in those with PTX3 ≥ 5.3 ng/mL (p = 0.002). CONCLUSION: These results indicate the potential for use of PTX3 as an inflammatory biomarker for the prognosis of patients with hepatic cirrhosis.

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.

BACKGROUND: Experimental studies in animal models and case reports in humans have described the hepatotoxic potential of cocaine. However, there are few data regarding the clinical and laboratory characteristics of patients admitted for cocaine intoxication, particularly regarding the status of the liver enzymes. GOAL: To investigate the significance of alanine aminotransferase (ALT) levels in individuals hospitalized for acute cocaine intoxication. METHODS: Retrospective study with standardized chart review that included patients admitted between January 2003 and December 2010. Bivariate analyses were used to investigate factors associated with ALT above the upper tertile according to gender. Cases of marked ALT elevation were described in detail. RESULTS: Ninety-three patients were included (79% men, mean age of 27.73±9.97 y). ALT above the upper tertile was associated with higher aspartate aminotransferase (AST), creatine phosphokinase, creatinine, and international normalized ratio. Higher levels of ALT were also related to acute renal failure and death. Five subjects had severe ALT elevation during follow-up and all had evidence of hepatocellular dysfunction (jaundice, prolonged prothrombin time with or without hepatic encephalopathy), rhabdomyolysis, and acute renal failure. AST/ALT ratio <2 was present in 2 subjects with severe ALT elevation at admission, but AST/ALT ratio >2 was observed in 3 cases with evidence of progression to acute liver injury. CONCLUSIONS: In acute cocaine intoxication, higher ALT levels were associated with evidence of muscle damage, progression to acute renal failure, and death. Severe liver damage was observed in 5% of the sample and was associated with rhabdomyolysis and renal failure in all cases.

BACKGROUND: Although several prognostic models have been proposed for cirrhotic patients listed for transplantation, the performance of these scores as predictors of mortality in patients admitted for acute decompensation of cirrhosis has not been satisfactorily investigated. AIMS: To study MELD, MELD-Na, MESO, iMELD, Refit-MELD and Refit MELD-Na models as prognostic predictors in cirrhotic patients admitted for acute decompensation, and to compare their performance between admission and 48 hours of hospitalization to predict in-hospital mortality. MATERIAL AND METHODS: This cohort study included cirrhotic patients admitted to hospital due to complications of the disease. Individuals were evaluated on admission and after 48 h of hospitalization, and mortality was evaluated during the present admission. RESULTS: One hundred and twenty-three subjects with a mean age of 54.26 ± 10.79 years were included; 76.4% were male. Mean MELD score was 16.43 ± 7.08 and 52.0% of patients were Child-Pugh C. Twenty-seven patients (22.0%) died during hospitalization. Similar areas under the curve (AUROCs) for prognosis of mortality were observed when different models were compared on admission (P > 0.05) and after 48 h of hospitalization (P > 0.05). When models executed after 48 h of hospitalization were compared to their corresponding model calculated on admission, significantly higher AUROCs were obtained for all models (P < 0.05), except for MELD-Na (P = 0.075) and iMELD (P = 0.119). CONCLUSION: The studied models showed similar accuracy as predictors of in-hospital mortality in cirrhotic patients admitted for acute decompensation. However, the performance of these models was significantly better when applied 48 h after admission when compared to their calculation on admission.

INTRODUCTION: Lower 25-hydroxyvitamin D [25(OH)D] levels have been observed in cirrhotic patients and have been related to disease severity. However, most previous studies included patients with very advanced disease, lacking an adequate control for other variables that could interfere with vitamin D levels. We sought to investigate the prevalence of hypovitaminosis D and the factors related to its occurrence. MATERIAL AND METHODS: This cross-sectional study included 133 cirrhotic patients and 30 healthy controls. Bivariate and multivariate analyses were performed to determine factors associated with 25(OH)D levels below the lower tertile. Thirty patients who had been recently hospitalized were compared in two time points. RESULTS: Mean 25(OH)D levels were 32.34 ± 11.38 in controls and 27.03 ± 6.22 ng/mL in patients (P = 0.018). 25(OH)D levels were < 30 ng/mL in 69.9% and < 20 ng/mL in 14.3% of the sample. Levels of 25(OH)D below the lower tertile (< 24 ng/mL) were independently associated with higher triceps skinfold and non-Caucasian race. Parathyroid hormone above the reference value (65 pg/mL) was found in 24.6% of patients without association with 25(OH)D or severity of liver disease. Significantly lower levels of 25(OH)D were found at the time of acute decompensation of cirrhosis. CONCLUSIONS: In conclusion, hypovitaminosis D was prevalent in cirrhotics and it was associated with adiposity and non-Caucasian race in stable patients with relatively well preserved liver function. However, significantly lower levels were observed during admission for acute decompensation suggesting an impact of systemic inflammation or liver dysfunction on 25(OH)D levels.

Spondyloarthritis (SpA) is a musculoskeletal inflammatory disease linked with immune responses to intestinal microbiota, and subclinical intestinal ulcerations that are closely related to inflammatory bowel diseases. Helicobacter pylori is a common cause of gastroduodenal ulceration, and anti-Saccharomyces cerevisiae antibodies (ASCA) are associated with intestinal inflammation in both Crohn disease (CD) and SpA. We investigated the relationship between H. pylori and ASCA. Ninety-one patients with axial SpA and forty with CD were included. ASCA IgG/IgA and anti-H. pylori IgG titers were assessed by ELISA. The proportion of ASCA+ patients in the positive and negative anti-H. pylori IgG groups with SpA and CD were compared using Chi-square tests, and correlations were evaluated using the Spearman's coefficient. Anti-H. pylori IgG titers were significantly negatively correlated with the ASCA IgG (r = -0.563, p < 0.001) and IgA (r = -0.342, p = 0.019) titers in the axial SpA patients. The same pattern of negative correlation was also observed in the CD patients. Anti-H. pylori+ serology was significantly more frequent in axial SpA patients than in those with CD (52.4 vs. 18.4 %, p < 0.001), while ASCA+ serology was significantly more frequent in CD patients than in SpA patients. A negative correlation between the anti-H. pylori titers and ASCA was found for axial SpA and CD. Anti-H. pylori+ serology was more frequent in SpA than in CD, while ASCA positivity was more frequent in CD patients than in those with SpA. A possible influence of H. pylori on the development of ASCA needs further investigation.

AIM: To evaluate the use of intermittently scanned continuous glucose monitoring (isCGM) in patients with liver cirrhosis (LC). METHODS: Observational study including 30 outpatients with LC (Child-Pugh B/C): 10 without diabetes (DM) (G1), 10 with newly diagnosed DM by oral glucose tolerance test (G2), and 10 with a previous DM diagnosis (G3). isCGM (FreeStyle Libre Pro) was used for 56 days (four sensors/patient). Blood tests were performed at baseline and after 28 and 56 days. RESULTS: No differences were found in the baseline characteristics, except for higher age in G3. There were significant differences between G1, G2 and G3 in glucose management indicator (GMI) (5.28 ± 0.17, 6.03 ± 0.59, 6.86 ± 1.08%, P < .001), HbA1c (4.82 ± 0.39, 5.34 ± 1.26, 6.97 ± 1.47%, P < .001), average glucose (82.79 ± 7.06, 113.39 ± 24.32, 149.14 ± 45.31mg/dL, P < .001), time in range (TIR) (70.89 ± 9.76, 80.2 ± 13.55, 57.96 ± 17.96%, P = .006), and glucose variability (26.1 ± 5.0, 28.21 ± 5.39, 35.31 ± 6.85%, P = .004). There was discordance between GMI and HbA1c when all groups were considered together, with a mean difference of 0.35% (95% SD 0.17, 0.63). In G1, the mean difference was 0.46% (95% SD 0.19, 0.73) and in G2 0.69% (95% SD 0.45, 1.33). GMI and HbA1c were concordant in G3, with a mean difference of -0.10 % (95% SD [-0.59, 0.38]). CONCLUSION: Disagreements were found between the GMI and HbA1c levels in patients with LC. isCGM was able to detect abnormalities in glycemic control that would not be detected by monitoring with HbA1c, suggesting that isCGM can be useful in assessing glycemic control in patients with LC.
RESUMEN
Intestinal perforation is described in coeliac disease in the setting of refractoriness or Enteropathy-Associated T-cell Lymphoma (EATL). We report the case of a man with untreated coeliac disease who presented intestinal perforation and was diagnosed with EATL over one year later.

INTRODUCTION: Adipose tissue as an endocrine organ is responsible for the release of multiple cytokines, which have the most diverse metabolic functions. Therefore, it is extremely important to preserve its physiological health in order to avoid local and systemic disorders. Experiments available in literature show the importance of the nitric oxide (NO)/guanosine 3'5' cyclic monophosphate (cGMP)/protein kinase G (PKG) pathway in adipocyte biology. Phosphodiesterase 5 (PDE5) is an enzyme responsible for cGMP inactivation, and the use of its inhibitors can be an alternative in the search of a more balanced adipose tissue. OBJECTIVE: This review aims to describe the PDE5 role and the possibility of using PDE5 inhibitors in adipocyte physiology derangements and their consequences. DESIGN AND METHODS: Studies published in the last 10years that related PDE5 and its inhibitors to adipose tissue were raised in major databases. RESULTS: PDE5 is present in adipocyte, and PDE5 inhibitors can promote adipogenesis, interfere with adipokines secretion, decrease inflammatory markers expression, and increase the thermogenic potential of white adipose tissue. CONCLUSIONS: PDE5 plays an important role in adipocyte physiology and the use of its inhibitors may prove a useful tool to combat adipose tissue disorders and its highest expression, metabolic syndrome.

INTRODUCTION: Bacterial infection is a frequent complication in patients with decompensated liver cirrhosis and is related to high mortality rates during follow-up of these individuals. We sought to evaluate the diagnostic value of C-reactive protein (CRP) and procalcitonin (PCT) in diagnosing infection and to investigate the relationship between these biomarkers and mortality after hospital admission. MATERIAL AND METHODS: Prospective study that included cirrhotic patients admitted to the hospital due to complications of the disease. The diagnostic accuracy of CRP and PCT for the diagnosis of infection was evaluated by estimating the sensitivity and specificity and by measuring the area under the receiver operating characteristics curve (AUROC). RESULTS: A total of 64 patients and 81 hospitalizations were analyzed during the study. The mean age was 54.31 ± 11.87 years with male predominance (68.8%). Significantly higher median CRP and PCT levels were observed among infected patients (P < 0.001). The AUROC of CRP and PCT for the diagnosis of infection were 0.835 ± 0.052 and 0.860 ± 0.047, respectively (P = 0.273). CRP levels > 29.5 exhibited sensitivity of 82% and specificity of 81% for the diagnosis of bacterial infection. Similarly, PCT levels > 1.10 showed sensitivity of 67% and specificity of 90%. Significantly higher levels of CRP (P = 0.026) and PCT (P = 0.001) were observed among those who died within three months after admission. CONCLUSION: CRP and PCT were reliable markers of bacterial infection in subjects admitted due to complications of liver cirrhosis and higher levels of these tests are related to short-term mortality in those patients.
