Proton pump inhibitors(PPIs) represent a milestone in the treatment of acid-related diseases, and are the mainstay in preventing upper gastrointestinal bleeding in high-risk patients treated with ...nonsteroidal antiinflammatory drugs(NSAIDs) or low-dose aspirin. However, this beneficial effect does not extend to the lower gastrointestinal tract. PPIs do not prevent NSAID or aspirin-associated lower gastrointestinal bleeding(LGB). PPIs may increase both small bowel injury related to NSAIDs and low-dose aspirin treatment and the risk of LGB. Recent studies suggested that altering intestinal microbiota by PPIs may be involved in the pathogenesis of NSAID-enteropathy. An increase in LGB hospitalization rates may occur more frequently in older patients with more comorbidities and are associated with high hospital resource utilization, longer hospitalization, and increased mortality. Preventive strategies for NSAID and aspirin-associated gastrointestinal bleeding should be directed toward preventing both upper and lower gastrointestinal damage. Future research should be directed toward identifying patients at low-risk for gastrointestinal events associated with the use of NSAIDs or aspirin to avoid inappropriate PPI prescribing. Alternatively, the efficacy of new pharmacologic strategies should be evaluated in high-risk groups, with the aim of reducing the risk of both upper and lower gastrointestinal bleeding in these patients.
The age of liver donors has been increasing in the past several years because of a donor shortage. In the United States, 33% of donors are age 50 years or older, as are more than 50% in some European ...countries. The impact of donor age on liver transplantation(LT) has been analyzed in several studies with contradictory conclusions. Nevertheless, recent analyses of the largest databases demonstrate that having an older donor is a risk factor for graft failure. Donor age is included as a risk factor in the more relevant graft survival scores, such as the Donor Risk Index, donor age and Model for End-stage Liver Disease, Survival Outcomes Following Liver Transplantation, and the Balance of Risk. The use of old donors is related to an increased rate of biliary complications and hepatitis C virus-related graft failure. Although liver function does not seem to be significantly affected by age, the incidence of several liver diseases increases with age, and the capacity of the liver to manage or overcome liver diseases or external injuries decreases. In this paper, the importance of age in LT outcomes, the role of donor age as a risk factor, and the influence of aging on liver regeneration are reviewed.
Liver diseases are the major predisposing conditions for the development of malnutrition, sarcopenia, and frailty. Recently, the mechanism of the onset of these complications has been better ...established. Regardless of the etiology of the underlying liver disease, the clinical manifestations are common. The main consequences are impaired dietary intake, altered macro- and micronutrient metabolism, energy metabolism disturbances, an increase in energy expenditure, nutrient malabsorption, sarcopenia, frailty, and osteopathy. These complications have direct effects on clinical outcomes, survival, and quality of life. The nutritional status should be assessed systematically and periodically during follow-up in these patients. Maintaining and preserving an adequate nutritional status is crucial and should be a mainstay of treatment. Although general nutritional interventions have been established, special considerations are needed in specific settings such as decompensated cirrhosis, alcohol-related liver disease, and metabolic-dysfunction-associated fatty liver disease. In this review, we summarize the physiopathology and factors that impact the nutritional status of liver disease. We review how to assess malnutrition and sarcopenia and how to prevent and manage these complications in this setting.
Background:
Faecal occult blood test (FOBT) has demonstrated effectiveness in colorectal cancer (CRC) screening. Faecal calprotectin (FC) has proven efficient for evaluating activity in inflammatory ...bowel disease (IBD), but its value in CRC detection is less established. Most symptomatic patients have benign pathologies, but still undergo colonoscopy in many settings.
Aims:
To evaluate the diagnostic accuracy and cost-effectiveness of the combination of FOBT plus FC in symptomatic patients.
Methods:
Patients who completed colonic investigations and returned stool samples, on which FOBT and FC were performed, were recruited prospectively. CRC, advanced adenoma, IBD and angiodysplasia were considered as relevant pathologies.
Results:
A total of 404 patients were included, of whom 87 (21.5%) had relevant pathologies. Sensitivity and specificity were 50.6% and 69.6% for FOBT, 78.2% and 54.4% for FC. Negative predictive value (NPV) was 90.1% for FC and 86.9% for FOBT. NPV for the combination of FOBT and FC was 94.1%, with a sensitivity and specificity of 88.5% and 50.3%. The area under ROC (receiver operator curve) (AUC) was 0.741 for FOBT, 0.736 for FC and 0.816 for the combination. The total cost for visits and procedures was €233,016 (€577/patient). Using a combination of FOBT and FC as pre-endoscopic tool allows colonoscopies to be reduced by 39.4%, reducing total costs by 20.5%.
Conclusion:
The combination of FOBT and FC has a better diagnostic accuracy compared with each test alone. Performing both tests before colonoscopy is a less costly and more effective strategy, reducing unnecessary procedures and complications.
Liver and pancreatic diseases have significant consequences on nutritional status, with direct effects on clinical outcomes, survival, and quality of life. Maintaining and preserving an adequate ...nutritional status is crucial and should be one of the goals of patients with liver or pancreatic disease. Thus, the nutritional status of such patients should be systematically assessed at follow-up. Recently, great progress has been made in this direction, and the relevant pathophysiological mechanisms have been better established. While the spectrum of these diseases is wide, and the mechanisms of the onset of malnutrition are numerous and interrelated, clinical and nutritional manifestations are common. The main consequences include an impaired dietary intake, altered macro and micronutrient metabolism, energy metabolism disturbances, an increase in energy expenditure, nutrient malabsorption, sarcopenia, and osteopathy. In this review, we summarize the factors contributing to malnutrition, and the effects on nutritional status and clinical outcomes of liver and pancreatic diseases. We explain the current knowledge on how to assess malnutrition and the efficacy of nutritional interventions in these settings.

Diverticular disease (DD) of the colon represents the most common disease affecting the large bowel in western countries. Its prevalence is increasing. Recent studies suggest that changes in gut ...microbiota could contribute to development of symptoms and complication. For this reason antibiotics play a key role in the management of both uncomplicated and complicated DD. Rifaximin has demonstrated to be effective in obtaining symptoms relief at 1 year in patients with uncomplicated DD and to improve symptoms and maintain periods of remission following acute colonic diverticulitis (AD). Despite absence of data that supports the routine use of antibiotic in uncomplicated AD, they are recommended in selected patients. In patients with AD that develop an abscess, conservative treatment with broad-spectrum antibiotics is successful in up to 70% of cases. In patients on conservative treatment where percutaneous drainage fails or peritonitis develops, surgery is considered the standard therapy. In conclusion antibiotics seem to remain the mainstay of treatment in symptomatic uncomplicated DD and AD. Inpatient management and intravenous antibiotics are necessary in complicated AD, while outpatient management is considered the best strategy in the majority of uncomplicated patients.
BACKGROUND.Calcineurin inhibitor-induced neurotoxicity (CIIN) is a common and debilitating side effect after liver transplantation (LT). Risk factors and impact on patient outcomes are not well ...defined. Our aim was to assess the incidence, risk factors, and clinical outcomes of CIIN.
METHODS.We retrospectively analyzed 175 LTs performed at our center between January 2010 and September 2016. Donor and recipient demographics as well as clinical variables pre-LT, intra-LT, and post-LT were assessed. All patients were on once-daily prolonged-release tacrolimus.
RESULTS.CIIN was described in 37 (21.4%) recipients. In univariate analysis, history of hepatic encephalopathy (P = 0.033), immunosuppressant treatment protocol (P = 0.041), donor age (P = 0.002), and pre-LT sodium serum levels (P = 0.004) were associated with CIIN. Patients undergoing LT for hepatocellular carcinoma had lower rates of CIIN (P = 0.040). In multivariate analysis, hepatic encephalopathy (odds ratio OR, 2.728; 95% confidence interval CI, 1.098-6.779; P = 0.031), pre-LT serum sodium levels (OR, 1.118 per mEq/L increase, 95% CI, 1.021-1.224; P = 0.016), and donor age (OR, 1.032 per y increase; 95% CI, 1.004-1.062; P = 0.027) were independent risk factors for developing CIIN. In the CIIN group, patients had longer intensive care unit (P = 0.024) and hospital (P = 0.008) stays and more changes in immunosuppressive treatment (54.1% vs 20.4%; P < 0.001).
CONCLUSIONS.Neurotoxicity remains frequent in patients on once-daily prolonged-release tacrolimus. Antecedents of hepatic encephalopathy, pre-LT sodium serum levels, and donor age are independent risk factors for developing CIIN after LT. CIIN is associated with longer hospital stays and changes in immunosuppressive treatment.
Most colonoscopies performed to evaluate gastrointestinal symptoms detect only non-relevant pathologies. We aimed to evaluate the diagnostic accuracy of a qualitative point-of-care (POC) test ...combining four biomarkers (haemoglobin, transferrin, calprotectin, and lactoferrin), a quantitative faecal immunochemical test (FIT) for haemoglobin, and a quantitative faecal calprotectin (FC) test in symptomatic patients prospectively recruited. Colorectal cancer (CRC), adenoma requiring surveillance, inflammatory bowel disease (IBD), microscopic colitis, and angiodysplasia were considered significant pathologies. A total of 571 patients were included. Significant pathology was diagnosed in 118 (20.7%), including 30 CRC cases (5.3%). The POC test yielded the highest negative predictive values: 94.8% for a significant pathology and 100% for CRC or IBD if the four markers turned negative (36.8% of the patients). Negative predictive values of FIT, FC, and its combination for diagnosis of a significant pathology were 88.4%, 87.6%, and 90.8%, respectively. Moreover, the positive predictive value using the POC test was 82.3% for significant pathology when all biomarkers tested positive (6% of the patients), with 70.6% of these patients diagnosed with CRC or IBD. The AUC of the POC test was 0.801 (95%CI 0.754-0.848) for the diagnosis of a significant pathology. Therefore, this POC faecal test allows the avoidance of unnecessary colonoscopies and prioritizes high risk symptomatic patients.
Neutrophil-to-lymphocyte ratio (NLR) is considered a prognostic factor in patients with hepatocellular carcinoma (HCC). Our aim is to investigate the prognostic significance of NLR in patients with ...HCC treated with sorafenib.
Median follow-up time was 7 months. Patients were mostly in the intermediate (27.3%) or advanced (72.7%) BCLC stages, 38.6% had vascular invasion and 27.5% extrahepatic disease. A large proportion (38.9%) had been previously treated with TACE. Liver function was preserved: 65.8% were classed as Child A. Median overall survival was 7.7 months (95% CI: 5.8-9.6). In univariate analysis, vascular invasion (
= 0.004), ECOG-PS ≥ 1 (
< 0.001), high bilirubin (
< 0.001), clinical ascites (
= 0.036), BCLC stage (
= 0.004), no previous TACE (
= 0.041) and NRL ≥ 2.3 (
= 0.005) were predictors of poor survival. Skin toxicity (
= 0.039) or hypertension (
= 0.033) during treatment were related to better survival. In multivariate analysis NLR ≥ 2.3 HR 1.72 (95% CI: 1.03-2.71), hyperbilirubinemia HR 3.42 (95% CI: 1.87-6.25) and ECOG-PS ≥ 1 HR 1.97 (95% CI: 1.19-3.26) were found as independent indicators of poor overall survival. Dermatologic adverse effects were an indicator of good overall survival HR 0.59 (95% CI: 0.38-0.92).
One hundred and fifty-four consecutive HCC patients treated with sorafenib in four different Spanish hospitals between August 2005 and October 2013 were analysed. Clinical, laboratory, and tumour features were obtained. Survival was calculated from the moment sorafenib treatment was initiated. Log-rank and Cox regression were used to analyse the ability of NLR to predict survival.
NLR is an independent prognostic indicator for overall survival in HCC patients treated with sorafenib.
Introduction:
The fecal immunochemical test (FIT) has been established as a cost-effective test in colon cancer screening programmes. This test could also be helpful in symptomatic patients prior to ...colonoscopy, but data about diagnostic performance, and accurate cut-off values for these patients are still scarce.
Materials and Methods:
Prospective study that included consecutive unselected patients with gastrointestinal symptoms referred for colonoscopy between November 2016 and June 2018. We performed a FIT (FOB Gold
®
test, cut-off 20 micrograms of Hb/gram of feces) prior to colonoscopy and determined the accuracy of FIT in terms of sensitivity, specificity, positive and negative predictive value for clinically significant pathology, advanced neoplasia, and colorectal cancer in symptomatic patients, using two different cut-off values.
Results:
A total of 727 patients (44.3% men, aged 58.5 ± 14.9 years) was included in the study. The main symptom was history of previous (non-active) rectal bleeding (34.7%), followed by diarrhea (15.0%). Over one quarter of the patients (25.9%) had a positive FIT result. The caecal intubation rate was 95.5%. Clinically significant pathology was identified in 142 colonoscopies (19.5%), advanced neoplasia in 115 (15.8%) and colorectal cancer in 36 colonoscopies (5.0%). FIT performed very well for clinically significant pathology, advanced neoplasia and cancer, with a high negative predictive value (NPV). Reducing the cut-off value to 10 μg/g yielded similar NPV results, with a decrease in specificity. Using a combination of symptoms with a positive FIT result did not improve FIT performance. Only specificity was slightly higher compared to FIT alone, but this was paralleled by a decrease in sensitivity and NPV for cancer and clinically significant pathology. The odds of presenting clinically significant pathology, advanced neoplasia, or cancer increased with FIT concentration.
Conclusions:
The specificity and NPV of FIT for clinically significant pathology, advanced neoplasia, and cancer are high in symptomatic patients. FIT is a helpful test for determining the need to perform further studies. It may not be necessary to reduce the cut-off value for symptomatic patients, since FIT performance with the current standard cut-off value used in colorectal cancer screening was accurate. FIT can be used to avoid or prioritize colonoscopy procedures.
