Early Detection of Advanced Fatty Liver Disease
Prospective Study: Early Detection of Advanced Fatty Liver Disease in the General Adult Population by Using Non-Alcoholic Fatty Liver Disease Score and Elastography
Non-alcoholic fatty liver disease is the most common cause of chronic liver disease in the western world, affecting one in every three subjects.
The investigators hypothesize that a patient population without known liver disease has a certain percentage of patients with liver fibrosis who are undiagnosed and not monitored.

Conditions
Detailed Description
The investigators will run an algorithm for the non-invasive diagnosis of advanced fibrosis in non-alcoholic fatty liver disease on a participants without known liver disease.
Nafld Score and Elastography are now being used to predict the severity of liver fibrosis and deciding whether the patient is going to a biopsy, clinical follow-up or further investigation of liver cirrhosis and complications.
The detection of participants with Nafld Score more than 0.675 (advanced fibrosis) will enroll them to an elastography test. Participants with advanced fibrosis according to elastography will be introduced to follow-up and treatment that should delay or prevent progression of the disease to more advanced conditions like: cirrhosis, portal hypertension, esophageal varicose veins and hepatocellular carcinoma.
If the investigators find that the results of the study are consistent with their hypothesis, this will lead to applying the flowchart to a larger sample of population in order to use it as a future survey.
Moreover, the investigators will check whether there is a correlation between Nafld Score and elastography in participants without know liver disease with Nafld Score more than 0.675.

Non-Alcoholic Fatty Liver Disease Score
Time Frame: Up to five minutes
|
Non-alcoholic fatty liver disease Score (Nafld Score) is a non-invasive scoring system based on several laboratory tests that helps to estimate the amount of scarring in the liver. The score is made up of six parameters: age, BMI(body mass index), aspartate aminotransferase(AST) / alanine transaminase(ALT), platelet count, impaired fasting glucose(IFG), albumin. The Nafld Score formula is: -1.675 + 0.037 × age (years) + 0.094 × BMI (kg/m^2) + 1.13 × IFG/diabetes (yes = 1, no = 0) + 0.99 × AST/ALT ratio - 0.013 × platelets (×10^9/l) - 0.66 × albumin (g/dl). 2 cutoff points were selected to identify the presence (> 0.675) and absence (< -1.455) of significant fibrosis. < -1.455: predictor of absence of significant fibrosis (F0-F2 fibrosis), negative predictive value 93% . between -1.455 and 0.675: indeterminate score. >0.675: predictor of presence of significant fibrosis (F3-F4 fibrosis), positive predictive value of 90%. The score will be calculated for all the participants. |

Elastography Test
Time Frame: Up to two hours
|
Ultrasound Elastography is a non-invasive test which uses the technology of Shear Wave Elastography (SWE) obtained from the right liver lobe for staging liver fibrosis according to Metavir Fibrosis Score with sensitivity between 86% -98% and specificity between 90% -93%. Metavir Fibrosis Score is a system used to assess the extent of inflammation and fibrosis by histopathological evaluation in a liver biopsy. Liver fibrosis assessed by Shear Wave Elastography is well correlated to biopsy using Metavir Score. Participants with Nafld Score above 0.675 will undergo ShearWave Elastography. The outcome of the test will be correlated to Metavir Score system according to the chart below: SWE (kiloPascal) , METAVIR score, Fibrosis Level. Below 5 , F0 , No fibrosis. 5.0-7.1 , F1 , Mild Fibrosis. 7.1-8.7 , F2 , Significant Fibrosis. 8.7-10.4 , F3 , Sever Fibrosis. 10.4-19 , F4 , Cirrhosis. |
