Effect of Dapagliflozin on Metabolic Parameters in Patients With Non-Alcoholic Fatty Liver Disease

This study was designed to assess the effect of dapagliflozin on body weight, blood sugar, liver enzymes, and blood fats in adults with non-alcoholic fatty liver disease (NAFLD), a condition involving excess fat accumulation in the liver. The study hypothesis was that changes in these measurements after 12 weeks would differ significantly between participants receiving dapagliflozin and those receiving placebo. The study was designed as a randomized, single-blind trial at the Department of Medicine, Shalamar Hospital, Lahore. Planned enrolment was 146 adults aged 20-70 years with NAFLD confirmed by ultrasound and a body mass index of at least 29 kg/m². Participants were to be randomly assigned to two equal groups of 73. One group was to receive dapagliflozin 10 mg by mouth once daily for 12 weeks, while the other was to receive an identical-looking placebo tablet containing no active medicine. Participants were to remain unaware of their assigned treatment. Both groups were to receive the same advice regarding diet, weight reduction, physical activity, and management of metabolic risk factors. The protocol specified measurements of body weight, body mass index, fasting blood sugar, HbA1c-a measure of average blood sugar-and liver enzymes before treatment and after 12 weeks. Blood fats, including cholesterol and triglycerides, and the ultrasound grade of liver fat were also included. Follow-up visits were scheduled every four weeks to assess medication use and record side effects. The planned analysis compared changes from baseline between the two treatment groups.

Lifestyle, Dietary Patterns, and Cardiometabolic Risk in Metabolic Dysfunction-Associated Steatotic Liver Disease Among People Living With HIV

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease, is an increasingly recognized comorbidity in people living with human immunodeficiency virus (HIV). Chronic low-grade inflammation, altered lipid metabolism, and certain antiretroviral therapy (ART) regimens may heighten the vulnerability of people living with HIV (PLWH) to liver fat accumulation, progressive liver fibrosis, and cardiometabolic complications. The primary purpose of this observational case-control study is to determine the prevalence, clinical characteristics, and laboratory findings of MASLD and hepatic fibrosis among PLWH compared with matched HIV-negative individuals. The study also aims to evaluate dietary quality, lifestyle habits, and cardiovascular risk profiles in both groups, and to determine whether adherence to a healthy lifestyle protects against significant liver disease. Adult participants (aged 18 years and older) attending the Department of Tropical Medicine and Gastroenterology at Assiut University Hospitals will be enrolled into two groups: people living with HIV and HIV-negative individuals matched by age, sex, and degree of liver steatosis. All participants will complete the following non-invasive evaluations: * Hepatic Assessment: Abdominal ultrasound and transient elastography (FibroScan) to detect fatty liver and quantify liver stiffness, alongside non-invasive scoring systems (FIB-4 score and NAFLD Fibrosis Score). * Laboratory Investigations: Fasting blood tests including liver function tests, lipid profiles, glycemic status (HbA1c), kidney function, complete blood count, and immune markers (CD4+ T-cell count and CD4/CD8 ratio). * Physical and Body Measurements: Measurement of body mass index (BMI), waist circumference, and mid-arm muscle circumference (MAMC). * Dietary and Lifestyle Questionnaires: Validated assessment tools including the Food Frequency Questionnaire (FFQ), Short Healthy Eating Index (sHEI), and Healthy Lifestyle Questionnaire to quantify nutritional quality, physical activity, and daily lifestyle habits. * Cardiometabolic Risk Calculation: Calculation of predicted cardiovascular risk using the American Heart Association PREVENT risk score. Findings from this study are intended to clarify the role of dietary quality and lifestyle factors in liver and metabolic health among people living with HIV, potentially informing proactive screening and management strategies.

Glycemic Effect of Diazoxide in NAFLD

The goal of this clinical trial is to compare a two-week course of diazoxide (at two different doses) and placebo in people with overweight/obesity and insulin resistance (IR) with, or at high risk for, non-alcoholic fatty liver disease (NAFLD). The main questions it aims to answer are how mitigation of compensatory hyperinsulinemia with diazoxide affects parameters of glucose and lipid metabolism (how people with IR and NAFLD respond to lowering high insulin levels so that the investigators can see what happens to how the liver handles fat and sugar). Participants will: * Take 27 doses of diazoxide (at 1 mg per kg of body weight per dose \[mpk\] or 2 mpk) or of placebo, over 14 days * Take 32 doses of heavy (deuterated) water (50 mL each) over 14 days * Have blood drawn and saliva collected after an overnight fast on four mornings over the two-week study period * Consume their total calculated daily caloric needs as divided into three meals per day * Wear a continuous glucose monitor for the two-week study period Researchers will compare fasting blood tests at intervals during the study period in participants randomized (like the flip of a coin) to diazoxide 1 mpk, diazoxide 2 mpk, or placebo, to see how the drug treatment affects plasma glucose, serum insulin, and serum lipid parameters (triglycerides, free fatty acids, and apolipoprotein B). They will also consume heavy (deuterated) water to assess de novo lipogenesis (building of new fatty acids by the liver).

NAFLD in Adolescents and Young Adults With PCOS

This project focuses on an at-risk adolescent and young adult population who may gain long-term health benefits from detection of risk factors at a young age. The primary aims of this proposal are: 1) To observe whether adolescents and young adults with Polycystic Ovary Syndrome (PCOS) are more likely to have elevated liver fat (\>/=4.8%) than controls by studying liver fat deposition measured by magnetic resonance spectroscopy (MRS); 2) To assess the association of percentage liver fat with biomarkers of Non-alcoholic fatty liver disease (NAFLD), dyslipidemia, insulin resistance and body composition in PCOS and controls. In the proposed study, 40 adolescents and young adults with PCOS and 40 age-comparable control subjects will be evaluated for metabolic disturbances and elevated liver fat using noninvasive and state-of-the-art techniques including MRI, dual-energy x-ray absorptiometry and an oral glucose tolerance test in order to fully assess the metabolic and body composition differences between these groups. This research proposal represents a critical step in understanding the metabolic and cardiovascular comorbidities of PCOS and their relationship to NAFLD. The investigator hopes to use the results generated by this research proposal in order to lay the groundwork for the prevention and treatment of metabolic disorders in adolescents with PCOS. The overarching goal is to decrease and prevent lifelong morbidity associated with this common disorder.

Impact of Soymilk on Liver Disease Severity of Children With Non-alcoholic Fatty Liver Disease (NAFLD)

A randomized, controlled study of standard soy milk consumption compared to 2% fat cow's milk consumption in children with Non-alcoholic Fatty Liver Disease (NAFLD). The investigators hypothesize that the daily consumption of soy isoflavones found in the soy milk will be beneficial in reducing NAFLD and other obesity-related comorbidities. The investigators do not expect any adverse endocrine or metabolomic effects from the consumption of soy isoflavones.

Nutritional Indices and Inflammatory Markers in MASLD

Metabolic Dysfunction-Associated steatotic Liver Diseases MASLD affects approximately 25 percent of population. Systemic inflammation plays role in MASLD progression. This cross-sectional observational study at Assiut University Hospitals will include 180 participants aged 18 to 65 years divided into 90 with MASLD and 90 without MASLD over one year. Nutritional indices Prognostic Nutritional Index PNI and Controlling Nutritional Status CONUT score will be calculated from albumin lymphocyte count and cholesterol. CBC-based inflammatory indices SIRI SII PIV PWR PLR MPR WNR NLR will be calculated. MASLD fibrosis score based on age BMI diabetes AST ALT ratio platelet albumin and FibroScan will assess fibrosis F0-F2 versus F3-F4. Aim to evaluate correlation between PNI CONUT and MASLD and role of inflammatory indices as predictors for MASLD and advanced fibrosis.

Impact of Overt and Subclinical Hypothyroidism on Liver Fibrosis in Patients With MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD), previously known as non-alcoholic fatty liver disease (NAFLD), is one of the most common chronic liver conditions globally. The progression of liver fibrosis (scarring) represents the most critical determinant of long-term liver-related morbidity and mortality in these patients. Thyroid hormones play an essential role in hepatic lipid metabolism, and thyroid dysfunction, specifically overt and subclinical hypothyroidism, has been implicated in the development and progression of MASLD. However, evidence regarding whether hypothyroidism independently worsens liver fibrosis severity remains inconsistent. This study aims to investigate the association between overt and subclinical hypothyroidism and the stages of liver fibrosis in adult Egyptian patients with MASLD using non-invasive diagnostic tools. A total of 120 adult patients diagnosed with MASLD attending the outpatient hepatology and endocrinology clinics at Assiut University Hospital will be enrolled, consisting of 60 patients with hypothyroidism and 60 euthyroid controls. All participants will undergo standardized clinical assessments, anthropometric measurements, and laboratory investigations, including thyroid function panels (TSH and free T4), liver function tests, lipid profiles, and glycemic markers. Hepatic steatosis will be evaluated via abdominal ultrasound, while liver fibrosis severity will be assessed using transient elastography (FibroScan) to measure liver stiffness, alongside validated blood-based scoring models (FIB-4 index and NAFLD Fibrosis Score). Comparing these findings across groups will help clarify whether thyroid deficiency acts as an independent contributor to advanced liver fibrosis.

12-Month Once-a-week HIIT Improves Body Adiposity and Liver Fat

Obesity and non-alcoholic fatty liver disease (NAFLD) are two related growing epidemics that are becoming pressing public health concerns. High-intensity interval training (HIIT) is a promising cost-effective and time-efficient exercise modality for managing obesity and NAFLD. However, patients with obesity and NAFLD are generally inactive and unfit, and might feel intimidated by the frequency of the prescribed HIIT (conventionally three times weekly). Previous HIIT studies, mostly over 2-4 month periods, showed that the participants could accomplish this exercise frequency under a controlled laboratory environment, but the long-term adherence and sustainability, especially in a field setting, remains uncertain. The situation is more unclear if we also consider those individuals who refused to participate possibly because of their overwhelming perceptions or low self-efficacy toward HIIT. Thus, logically, HIIT at a lower frequency would be practical and more suitable for patients with obesity and NAFLD, but the minimum exercise frequency required to improve health, especially in the long-term, is unknown. This proposed study aims to examine the effectiveness of long-term low-frequency HIIT for improving body adiposity and liver fat in centrally obese adults. The premise of this proposal is supported by recent findings that HIIT performed once a week could improve cardiorespiratory fitness, blood pressure, cardiac morphology, metabolic capacity, muscle power, and lean mass. This study will provide evidence for the benefits of long-term low-frequency HIIT with a follow-up period to assess its effectiveness, safety, adherence, and sustainability. We expect this intervention will enhance the practical suitability of HIIT in inactive obese adults and will provide evidence for low-frequency HIIT as a new exercise option in the management of obesity and NAFLD.

Dynamic Changes and Risk Factors of Fibrosis and Steatosis Progression in Nonalcoholic Fatty Liver Disease

It is an observational study of non alcoholic fatty liver disease (NAFLD) patients with a calculated sample size of 500. Liver biopsy proved NAFLD patients will be recruited in this study for 10 years follow-up. Patients will be assessed at baseline, at every six months for blood count, liver function test, fasting blood-glucose, fasting insulin, ferritin, liver ultrasonography, and liver stiffness.

Ursodeoxycholic Acid in Patients With NAFLD - Clinical Observation

Patients with NAFLD indicated for ursodeoxycholic acid treatment ("by SPC: cholestatic hepatitis") will be offered an observational study. Examinations will be performed before the treatment and after 6month period. Laboratory parameters, non-invasive indices, liver elastography, cardiovascular parameters and liver MR spectroscopy will be performed.

Characteristics of NAFLD Among Type 2 Diabetes Patients

Type 2 diabetes patients have a high risk of developing NAFLD. This was confirmed during previous research, a high prevalence of NAFLD among type 2 diabetes mellitus patients was found. The investigators want to determine the characteristics of this population.

MASLD in Primary Hypothyroidism and Efficacy of Dapaglifozin

Non-alcoholic fatty liver disease (NAFLD) is a global epidemic with a prevalence of 25-40%.Primary Hypothyroidism is one of Endocrinopathies who are at risk of developing NAFLD/NASH and estimated prevalence of Primary Hypothyroidism in NAFLD patients is 10-15 %.Though First line Management is Dietary changes and lifestyle modifications(LSM),unfortunately Adherence to Lifestyle has been poor,rise of Lean NAFLD is on rise, faster progression of NAFLD,evolving risk factors for NAFLD like endocrinopathies,these push need for Pharmacotherapy.Currently therapies for NAFLD patients without diabetes mellitus (DM) are limited, and are associated with various adverse side effects. Sodium-glucose cotransporter type-2 (SGLT2) inhibitors can reduce hepatic fat content in patients with DM which is independent of glycemic control. However, the role of SGLT2 inhibitors in NAFLD patients without DM has not been investigated.Magnetic resonance imaging-derived proton density fat fraction (MRI-PDFF) is an emerging non-invasive imaging technique, and is more sensitive than liver biopsy/histology in quantifying liver fat change. Liver stiffness measurement (LSM) by Transient Elastography is a non-invasive method to diagnose fibrosis/cirrhosis with high accuracy.The novelty of utilizing the concept of "drug repositioning" by changing the role of SGLT2 inhibitors in treating DM to treating NAFLD in patients without DM deserves exploration.The investigators propose a double-blind, randomized, placebo-controlled trial to compare the effects of Dapagliflozin (a type of SLGT2 inhibitors) versus placebo (in a 1:1 ratio) in reducing hepatic fat content as measured by MRI-PDFF in NAFLD patients with Primary Hypothyroidism.The study results will determine whether SGLT2 inhibitors can reduce hepatic steatosis/hepatic fibrosis in NAFLD patients with Primary Hypothyroidism.

Hypothyroidism and Liver Fibrosis Severity in MASLD

Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most common chronic liver disease worldwide, characterized by excess fat accumulation in the liver associated with metabolic risk factors such as obesity and type 2 diabetes. Over time, MASLD can progress from simple liver fat accumulation to liver inflammation and fibrosis (scar tissue formation), which is the most critical factor predicting long-term liver health complications. Thyroid hormones play a key role in controlling hepatic metabolism and lipid handling. An underactive thyroid gland (hypothyroidism), including both overt and mild (subclinical) forms, has been linked to increased fat accumulation and advanced fibrosis in the liver. However, further evidence is needed regarding how thyroid dysfunction relates to liver fibrosis using modern, non-invasive assessment tools in clinical practice. The primary purpose of this observational case-control study is to evaluate the relationship between hypothyroidism and the severity of liver fibrosis in adult patients with MASLD. Participants diagnosed with MASLD will be categorized into two groups based on thyroid function: patients with hypothyroidism (cases) and patients with normal thyroid function (controls). All participants will undergo standard clinical assessments, routine fasting laboratory tests, thyroid function tests, abdominal ultrasound, and transient elastography (FibroScan) to measure liver stiffness and fibrosis severity non-invasively. Non-invasive fibrosis scores, including the FIB-4 index and the NAFLD Fibrosis Score (NFS), will also be calculated. The findings will help determine whether hypothyroidism is independently associated with more severe liver fibrosis in patients with MASLD, potentially guiding screening and management strategies.

Human Models of Selective Insulin Resistance: Alpelisib, Part I

The goal of this clinical trial is to understand how the blood sugar-lowering hormone insulin works in healthy adults versus those who are at risk for type 2 diabetes. The study will use a drug called alpelisib, which interferes with insulin's actions in the body, to answer the study's main question: does the liver continue to respond to insulin's stimulation of fat production even when it loses the ability to stop making glucose (sugar) in response to insulin. Researchers will compare the impact of single doses of both alpelisib and placebo (inert non-drug) in random order (like flipping a coin) in study participants. Participants will be asked to stay twice overnight in the hospital, take single doses of alpelisib and placebo (one or the other on each of the two hospital stays), and receive intravenous (into the vein) infusions of non-radioactive "tracer" molecules that allow researchers to measure the production of glucose (sugar) and fats by the liver. Measurements will be done both while participants are fasting (not eating or drinking other than water) and while consuming a standardized diet of nutritional beverages. The objective is to evaluate the effect of lowering insulin levels, while maintaining constant mild hyperglycemia, on plasma glucose and lipid levels.

Impact of Lifestyle Interventions on Cognitive Decline in Non-alcoholic Fatty Liver Disease

This study investigates whether a structured lifestyle program can help improve thinking skills and liver health in adults with Non-Alcoholic Fatty Liver Disease (NAFLD). We are enrolling 45 participants, aged 18-42, who will be randomly assigned to one of three groups for six months: one receiving general health advice, a second following a supervised Mediterranean diet plan, and a third combining the same diet with a regular walking program. The main goal is to see if these diet and exercise interventions can lead to better scores on memory and reasoning tests, reduce liver stiffness measured by a painless scan (FibroScan), and improve related blood markers of inflammation and hormone balance.

InAdvance: Surveillance, Prevention, and Interception in a Population at Risk for Cancer

This research study is creating a way to collect and store specimens and information from participants who may be at an increased risk of developing cancer, or has been diagnosed with an early phase of a cancer or a family member who has a family member with a precursor condition for cancer. * The objective of this study is to identify exposures as well as clinical, molecular, and pathological changes that can be used to predict early development of cancer, malignant transformation, and risks of progression to symptomatic cancer that can ultimately be fatal. * The ultimate goal is to identify novel markers of early detection and risk stratification to drive potential therapeutic approaches to intercept progression to cancer.

Non-Alcoholic Fatty Liver Disease, the HEpatic Response to Oral Glucose, and the Effect of Semaglutide (NAFLD HEROES)

Background: In non-alcoholic fatty liver disease (NAFLD), fat accumulates in the liver and can cause damage. Researchers want to learn what causes the damage NAFLD, and to see if a medication can help. Objective: To find out how the liver in people with NAFLD responds to feeding, and how this relates to their response to the drug semaglutide. Eligibility: People with NAFLD and healthy volunteers ages 18 and older Design: Participants will be screened with: Medical history Physical exam Blood tests Imaging: A machine will take pictures of the participant s body. Within 2-8 weeks of enrollment, participants will stay in the clinic for several days. This includes: Blood, urine, heart, and imaging tests For NAFLD participants only: A needle-like device will remove a small biopsy of the liver and fatty tissue. Participants will be alone in a special room for 5 hours. They will breathe through a tube under the nostrils. They will have blood drawn several times. The baseline visit concludes participation for healthy volunteers but NAFLD participants will contine. About 6 weeks after discharge, participants will stay in the clinic again and repeat the tests. They will get their first semaglutide dose by injection. Participants will have visits weeks 1, 2, 4, 8, 12, 16, 20, and 24 of treatment. Visits include blood tests. Participants will inject semaglutide once a week at home. At week 30, participants will stay in the clinic again and repeat the tests. Participants will have a final visit 12 weeks after stopping treatment. This includes blood and urine tests. ...

Harnessing Macrophage Lysosomal Lipid Metabolism in Obesity (ATM)

The goal of this study is to evaluate the role of transcription factor EB (TFEB) in adipose (fat) tissue macrophages (ATM) in regulating adipose tissue and systemic metabolic function in obesity. The investigators will assess the differences in ATM lipid metabolism in people with metabolically abnormal obesity and lean individuals. Both groups will have: * screening visit * imaging (body composition testing - dual-energy x-ray absorptiometry (DEXA) scans, magnetic resonance imaging \[MRI\] and magnetic resonance spectroscopy \[MRS\] scans) * Overnight visit with intravenous infusion (IV), muscle, and fat tissue biopsies

Hyperpolarized Pyruvate (13C) Magnetic Resonance Imaging In Patients With Fatty Liver Disease

The recent development of dissolution dynamic nuclear polarization (DNP) technology for hyperpolarized (HP) 13C imaging offers a promising new avenue for non-invasively accessing fundamental metabolic changes associated with the progression of fatty liver disease in vivo. The purpose of this pilot study is to optimize sequence parameters for hyperpolarized 13C acquisition in the human liver and determine which metabolic changes can be seen in humans with simple, non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) when compared to healthy volunteers.

Fibrosis Lessens After Metabolic Surgery

Metabolic dysfunction-associated steatotic liver disease (MASLD), formerly known as non-alcoholic fatty liver disease (NAFLD), a major global public health concern, is commonly associated with obesity, diabetes, and dyslipidemia. MASLD is currently the most common cause of chronic liver disease affecting about 80% of people with obesity, ranging from simple fat deposits in the liver to Metabolic Dysfunction-Associated Steatohepatitis (MASH), cellular injury, advanced fibrosis, cirrhosis, or hepatocellular carcinoma. Patients with MASH are also at risk for cardiovascular disease and mortality. There is no universally approved medication for MASH. Weight loss remains the cornerstone of MASH treatment. Patients meeting the inclusion and exclusion criteria and who give informed consent will be enrolled in the trial and undergo the baseline liver biopsy (if none available). Approximately 120 patients with MASH and liver fibrosis (F1-F4 in baseline liver biopsy) will be randomized in a 1:1 ratio to metabolic surgery or medical treatment (incretin-based therapies ± other medical therapies for MASH) and followed for 2 years at which time a repeat liver biopsy will be performed for the assessment of the primary end point.

Nonalcoholic Steatohepatitis in Chinese Children

Nonalcoholic steatohepatitis (NASH) is now recognised as an increasing clinical problem in children. Steatosis without significant liver cell injury or fibrosis is the most common form of nonalcoholic fatty liver disease (NAFLD) in both adults and children. Studies in the adult population have variably suggested that steatosis is a benign nonprogressive condition and NASH is recognised as a potentially serious condition with significantly risk of morbidity and mortality. A growing body of evidence suggests that children with NASH frequently show histopathological features that differ from those of adults. The prevalence of this pattern in a wide range of paediatric cases as well as other histopathological lesions and their relevance and prognostic significance in children with NAFLD remains to be determined. Thus the investigators would like to conduct a study of biopsies and clinical information to document the histological features of paediatric NAFLD, to explore the natural history of paediatric NAFLD, and to determine the frequency and prognostic value of these features.

Moderately Carbohydrate-restricted Diet to Treat NAFLD in Adolescents

This will be a 6-month randomized clinical trial with two arms: moderately carbohydrate-restricted diet and a fat-restricted control diet. This 6-month study will have 2 phases: a 12-week controlled feeding phase and a 12-week "free living" phase. During the controlled feeding phase, all food will be provided to the families of the participants for the entirety of the 12 weeks. Participants (n=80) will have been diagnosed with NAFLD based on the presence of current evidence of active disease, which will be determined by the ongoing presence of hepatic steatosis estimated by diffusely echogenic liver via ultrasound suggestive of fatty liver and a serum alanine aminotransferase (ALT) level of 45 U/L or greater. All participants will be children and adolescents age 10-17 yrs.; will have an HbA1c \<7.0; and will be overweight or obese (BMI \>85th percentile). It is anticipated that most participants will be sedentary. The investigators will inquire as to routine physical activity at screening. All participants will be asked to maintain their usual level of physical activity throughout the study. Physical activity will be monitored via a smart watch provided to each participant at the beginning of the study, and participants will be queried weekly by the study dietitian regarding changes in physical activity. Participants who use oral contraceptives will be asked to maintain consistent use of these preparations throughout the study. Hormone use will be examined as a potential covariate in statistical analyses.

Accuracy of Imaging Techniques in Diagnosing Steatohepatitis and Fibrosis in NAFLD Patients

Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent condition, and when fatty liver is associated with inflammation and hepatocellular injury (steatohepatitis), it can lead to fibrosis, cirrhosis, liver failure and hepatocellular carcinoma. Liver biopsy is the gold standard for NAFLD assessment but has several drawbacks. Several drugs for NASH are now in phase 2-3 trials, and if medical treatments become available, non-invasive tools to identify patients who may benefit from a therapeutic intervention will be strongly needed. Some imaging methods have shown promising potential in fibrosis and NASH diagnosis. This study aims to evaluate the diagnostic accuracy of non-invasive imaging methods, including ultrasound (US) and Magnetic Resonance (MR) techniques, in diagnosing NASH and fibrosis in patients with or at high risk of NAFLD, using liver biopsy as the reference standard. Consecutive patients with a clinical indication for liver biopsy assessment of NAFLD are enrolled in this non-inferiority study. They undergo both a liver US and a multiparametric unenhanced liver MR examination. As reference standard, histological diagnosis of fibrosis and steatohepatitis made according to the fatty liver inhibition of progression (FLIP) algorithm is used. Sensitivity and specificity of imaging parameters alone or in different combinations will be calculated with the aim of finding one or more tests with at least 90% sensitivity/specificity compared to liver biopsy.
