Impact of sleeve gastrectomy on renal function in patients with morbid obesity: a 1-year prospective cohort study.

Purpose: Obesity is an independent risk factor for renal injury. A more favorable metabolic environment following weight loss may theoretically lead to improved renal function. We aimed to evaluate the evolution of renal function one year after sleeve gastrectomy in a large prospective cohort of patients with morbid obesity and assess the influence of fat-free mass (FFM) changes.

Adaptation of controlled attenuation parameter (CAP) measurement depth in morbidly obese patients addressed for bariatric surgery.

Background And Aim: The controlled attenuation parameter (CAP) using FibroScan (Echosens, Paris, France) M or XL probe has been developed for liver steatosis assessment. However, CAP performs poorly in patients with high body mass index. The aim of our study was to assess whether CAP is overestimated using the standard XL probe in patients with morbid obesity, and in the case of an overestimation, to reprocess the data at a greater depth to obtain the appropriate CAP (CAPa).

Predictive score of sarcopenia occurrence one year after bariatric surgery in severely obese patients.

Background And Aim: Sarcopenic obesity is a risk factor of morbidity and mortality. The aim of this study was to generate a predictive score of sarcopenia occurrence one year after bariatric surgery.

Patients And Methods: We conducted an observational prospective cohort study on a total of 184 severely obese patients admitted to our institution to undergo sleeve gastrectomy.

Controlled attenuation parameter for diagnosing steatosis in bariatric surgery candidates with suspected nonalcoholic fatty liver disease.

Introduction: Steatosis in patients with nonalcoholic fatty liver disease (NAFLD) is often benign, but may progress to fibrosis. The accurate diagnosis of hepatic steatosis is therefore important for clinical decision-making and prognostic assessments. The controlled attenuation parameter (CAP), a noninvasive measurement obtained with Fibro-Scan, has been developed for liver steatosis assessment.

Transient elastography alone and in combination with FibroTest for the diagnosis of hepatic fibrosis in alcoholic liver disease.

Background & Aims: The reliability of transient elastography (TE) to assess liver fibrosis is insufficiently validated in alcoholic liver disease (ALD). We aimed to validate the diagnostic utility of TE for liver fibrosis in patients with excessive alcohol consumption and evaluate whether Fibrotest adds diagnostic value relative to or in combination with TE.

Methods: We conducted a multicentre prospective study on a total of 217 heavy drinkers with high serum aminotransferase levels.

Adaptation of liver stiffness measurement depth in bariatric surgery candidates with suspected nonalcoholic fatty liver disease.

Background And Aims: A thick layer of subcutaneous adipose tissue may lead to an overestimation of liver stiffness by transient elastography. The aim of this study was to assess whether liver stiffness measurement (LSM) was overestimated using an XL probe in patients with severe obesity and, if so, to reprocess the data to the adapted depth to obtain the appropriate LSM (LSMa).

Methods: A total of 152 obese patients prospectively underwent bariatric surgery and needle liver biopsy.

The diagnostic accuracy of transient elastography for the diagnosis of liver fibrosis in bariatric surgery candidates with suspected NAFLD.

Background: Severe obesity and metabolic syndrome have been implicated in the development of nonalcoholic fatty liver disease (NAFLD). We evaluated the diagnostic value of liver stiffness measurement (LSM), by transient elastography (FibroScan®) in bariatric surgery candidates with suspected NAFLD.

Methods: A total of 100 prospectively included consecutive severely obese subjects underwent bariatric surgery with liver needle biopsy.

Alcohol withdrawal alleviates adipose tissue inflammation in patients with alcoholic liver disease.

Background & Aims: Patients with alcoholic liver disease (ALD) display inflammation of the subcutaneous adipose tissue (SAT) which correlates with liver lesions. We examined macrophage markers and polarization in the SAT of alcoholic patients and adipokine expression according to liver inflammation; we studied the consequences of alcohol withdrawal.

Patients And Methods: Forty-seven patients with ALD were prospectively included.

Comparison of Fibrotest and PGAA for the diagnosis of fibrosis stage in patients with alcoholic liver disease.

Background And Aims: The PGAA index was one of the first composite liver fibrosis markers. This study aims, prospectively, to confirm the diagnostic value of PGAA and Fibrotest in patients with alcoholic liver disease and to compare their diagnostic performances.

Patients And Methods: We prospectively included 200 consecutive patients (159 men and 41 women; mean age: 51±0.

Body fat distribution and risk factors for fibrosis in patients with alcoholic liver disease.

Background: Only a small proportion of alcoholic patients develop advanced liver disease, suggesting that factors other than alcohol intake may influence alcoholic liver disease (ALD) progression. We have shown that body mass index (BMI) is an independent risk factor for fibrosis in alcohol-induced liver disease and that adipose tissue inflammation is correlated with liver lesions in alcoholic patients. The aim of this study was to determine whether visceral adipose tissue, as assessed by abdominal height measurement, affected individual susceptibility to fibrosis in alcoholic patients.

Housekeeping gene variability in the liver of alcoholic patients.

Background: Quantification of gene expression using reverse transcription-quantitative polymerase chain reaction (RT-qPCR) requires normalization to an endogenous reference gene termed housekeeping gene (HKG). Many of the commonly used HKGs are regulated and vary under experimental conditions and disease stages. Alcoholic liver disease (ALD) is associated with several different liver histological lesions that may modulate HKG expression.

Harmful effect of adipose tissue on liver lesions in patients with alcoholic liver disease.

Background & Aims: Adipose tissue is an important source of cytokines. Excess weight is an independent risk factor for steatosis, acute alcoholic hepatitis (AAH), and cirrhosis in patients with alcoholic liver disease (ALD). In this study, we investigated the role of adipose tissue in human ALD.

Predictive factors for pure steatosis in alcoholic patients.

Background: Bearing in mind the mechanisms involved in nonalcoholic fatty liver disease, this study aims to verify whether metabolic syndrome or its various individual components are independent predictive factors for steatosis > or =10% in alcoholic patients.

Methods: This study included 281 consecutive alcoholic patients with abnormal liver tests and either normal liver histology or steatosis <10% (n = 119) or steatosis > or =10% (n = 162). Logistic regression analysis was used to study the relationship between metabolic syndrome components and various risk factors and the presence of steatosis > or =10%.

Diagnostic and prognostic values of noninvasive biomarkers of fibrosis in patients with alcoholic liver disease.

FibroTest has been validated as a biomarker of fibrosis in patients with chronic viral hepatitis, with a similar prognostic value as biopsy. The aim of the study was to compare the diagnostic and prognostic values of FibroTest versus the recently patented biomarkers, FibrometerA, and Hepascore. A total of 218 consecutive patients with ALD and available liver biopsy examination were included.
