简要总结
Transient elastography is novel non-invasive method for assessment of hepatic fibrosis in patients with chronic liver disease, by measuring liver stiffness. Transient elastography is a user friendly technique that can be easily performed at bedside or in outpatient clinic with immediate results and good reproducibility.
Liver stiffness values ranges from 2.5 to 75 kPa with lower values <6kPa suggest no fibrosis where as higher values above 14kPa suggests cirrhosis. In the present study the investigators hypothesis that the investigators can differentiate ACLF and acute severe viral hepatitis based on fibroscan as patients with underlying fibrosis with superadded inflammation would have higher fibroscan value than when patient have only inflammation with no underlying fibrosis and hence the investigators can avoid unnecessary test in such subgroup.
详细描述
Transient elastography is a novel non-invasive method that for the assessment of hepatic fibrosis in patients with chronic liver diseases, by measuring liver stiffness.
Acute on chronic liver failure: acute hepatic insult manifesting as jaundice and coagulopathy, complicated within 4 weeks by ascites and/or encephalopathy in patients with previously diagnosed or undiagnosed chronic liver disease.
Acute severe hepatitis: Acute severe hepatitis which is characterized by serum bilirubin > or = 10.0 mg/dL and international normalized ratio (INR) > or = 1.5.
Patients with acute severe viral hepatitis or acute on chronic liver failure will be enrolled in this prospective study after taking informed written consent. All patients will be evaluated at baseline as per standard protocol which include evaluation of etiology of disease and tests to exclude underlying liver disease which includes ultrasound/computed tomography and if necessary upper gastrointestinal endoscopy and liver biopsy if imaging shows any signs of underlying liver disease. the patients will be followed up for 1 month, all patients will undergo Fibroscan at the time of admission and thereafter at 1week and 4th week .
