Insuficiência Hepática Aguda Induzida pela Trazodona e Diazepam

Most antidepressant agents have the potential to cause liver injury, even at therapeutic doses. Nevertheless, drug-induced liver injury (DILI) from antidepressant agents is a rare event. There is no way to prevent idiopathic DILI, but the severity of the reaction may be minimized with prompt recognition and early withdrawal of the agent. We describe a rare case of a 63-year-old man presenting with acute liver failure after 3 months of trazodone and diazepam administration at normal therapeutic doses, requiring liver transplantation. This report should increase physicians' awareness of this complication and call attention to the regular monitoring of liver tests in patients taking trazodone, in order to prevent life-threatening complications.info:eu-repo/semantics/publishedVersio

How good is controlled attenuation parameter and fatty liver index for assessing liver steatosis in general population: correlation with ultrasound

Liver steatosis measurement by controlled attenuation parameter (CAP) is a non-invasive method for diagnosing steatosis, based on transient elastography. Its usefulness as screening procedure for hepatic steatosis in general population has not been previously evaluated. The aim of this study was to evaluate the diagnostic accuracy of CAP and fatty liver index (FLI) for detection and quantification of steatosis in general population

What is the role of the new index relative fat mass (RFM) in the assessment of nonalcoholic fatty liver disease (NAFLD)?

Introduction: Nonalcoholic fatty liver disease (NAFLD) is the liver manifestation of adiposopathy. Recently, a new score was developed to estimate body fat percentage (relative fat mass, RFM). We aimed to evaluate the value of RFM in predicting the presence and severity of NAFLD, compared with other anthropometric measurements. Methods: RFM, body mass index (BMI), and other anthropometric measurements were evaluated in two cohorts of subjects: a cohort from a Portuguese prospective epidemiological study (e_Cor) and morbidly obese patients with biopsy-proven NAFLD. We evaluated if RFM and BMI were related with the presence and severity of liver disease, which was assessed by noninvasive tools in the first cohort and by liver histology in the morbidly obese cohort. The independence of relations found in univariate analysis was assessed with multivariable logistic regression analysis. Results: In the general population cohort, 744 subjects (48% male) were enrolled. BMI-defined obesity was present in 23% and RFM-defined obesity in 86%. Insulin resistance (IR) related with BMI-defined obesity (OR 4.37 [2.16-8.84]) and weight (OR 1.05 [1.02-1.08]) in men, and waist circumference (WC) (OR 1.07 [1.03-1.11]) in women. Dyslipidemia and hypertension related with RFM-defined obesity in men (OR 2.96 [1.36-6.47] and OR 5.37 [1.31-22.06], respectively). Ultrasound-diagnosed NAFLD in 33% related with weight in men (OR 1.03 [1.003-1.06] and WC in women (OR 1.06 [1.02-1.10]). In men, ALT elevation related with weight (OR 1.04 [1.02-1.07]). In women, advanced fibrosis (estimated by NAFLD Fibrosis Score) associated with BMI-defined obesity (OR 42.43 [3.61-498.13]). In the morbidly obese cohort, 152 subjects were enrolled, of whom 84% were female, 37% had steatohepatitis, and 9.4% had advanced fibrosis. Adiponectin associated inversely and leptin positively with RFM in men. The severity of steatosis increased linearly with BMI and WC in women. Higher BMI associated with steatohepatitis in women and advanced fibrosis in men. Conclusion: RFM-defined obesity better predicted dyslipidemia and hypertension (though not IR) and adipokine imbalance; however, it did not add value to BMI-defined obesity in predicting NAFLD or liver injury.info:eu-repo/semantics/publishedVersio

Prevalence of alcoholic steatosis in the general adult Portuguese population

Background and Aims: Fatty liver is very frequent in the general population. Although many studies evaluated the prevalence of nonalcoholic fatty liver disease there is scarce information regarding alcoholic fatty liver. We aimed to estimate the prevalence of alcoholic hepatic steatosis, and to what extent it depended on obesity and its interaction.info:eu-repo/semantics/publishedVersio

Hepatic steatosis in an adult population: stronger correlation with the presence of obesity and insulin resistence than with the dietary pattern: results from a cross-sectional study

Background and Aims: Hepatic steatosis is very frequent in thegeneral population, mostly associated with obesity and insulinresistance. Typical dietary patterns have been difficult to identifywith controversial information. We aimed to estimate in a represen-tative sample of the Portuguese adult population, what was thecontribution of the dietary pattern in what concerns macronutrientsand food groups for the presence of steatosis as well as the othertraditional risk factors for steatosis.info:eu-repo/semantics/publishedVersio

Range of Normal Liver Stiffness and Factors Associated With Increased Stiffness Measurements in Apparently Healthy Individuals

Background & Aims: Transient elastography (TE) is a noninvasive technique used to measure liver stiffness to estimate the severity of fibrosis. The range of liver stiffness measurements (LSMs) in healthy individuals is unclear. We performed a systematic review to determine the range of LSMs, examined by TE, in healthy individuals and individuals who are susceptible to fibrosis. Methods: We collected data from 16,082 individuals, in 26 cohorts, identified from systematic searches of Embase, Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Cochrane Database of Systematic Reviews for studies of liver stiffness measurements. Studies analyzed included apparently healthy adults (normal levels of liver enzymes, low-risk alcohol use patterns, and negative for markers of viral hepatitis). The presence of diabetes, hypertension, dyslipidemia, or steatosis, based on ultrasound examination, was known for most participants. We performed a meta-analysis of data from individual participants. The cohort was divided into 4 groups; participants with a body mass index <30 kg/m2 were examined with the medium probe and those with a body mass index =30 kg/m2 were examined with the extra-large probe. Linear regression models were conducted after adjusting for potential confounding factors of LSMs. We performed several sensitivity analyses. Results: We established LSM ranges for healthy individuals measured with both probes—these did not change significantly in sensitivity analyses of individuals with platelets =150,000/mm3 and levels of alanine aminotransferase =33 IU/L in men or =25 IU/L in women. In multivariate analysis, factors that modified LSMs with statistical significance included diabetes, dyslipidemia, waist circumference, level of aspartate aminotransferase, and systolic blood pressure at examination time. Significant increases in LSMs were associated with the metabolic syndrome in individuals examined by either probe. Diabetes in obese individuals increased the risk of LSMs in the range associated with advanced fibrosis. Conclusions: In a systematic review and meta-analysis of data from individual participants, we established a comprehensive set of LSM ranges, measured by TE in large cohorts of healthy individuals and persons susceptible to hepatic fibrosis. Regression analyses identified factors associated with increased LSMs obtained by TE with the medium and extra-large probes
