Korábbi kezelés

• Clinical or histological evidence of alcoholic liver disease: Regular and excessive use of alcohol within the 2 years prior to interview defined as alcohol intake greater than 14 drinks per week in a man or greater than 7 drinks per week in a woman. Approximately 10 g of alcohol equals one 'drink' unit. One unit equals 1 ounce of distilled spirits, one 12-oz beer, or one 4-oz glass of wine

Más betegség

• Short bowel syndrome
• History of gastric or jejunoileal bypass preceding the diagnosis of NAFLD. Bariatric surgery performed following enrollment is not exclusionary. Liver biopsies obtained during bariatric surgery cannot be used for enrollment because of the associated surgical or anesthetic acute changes and the weight loss efforts that precede bariatric surgery
• History of biliopancreatic diversion
• Evidence of advanced liver disease defined as a Child-Pugh-Turcotte score equal to or greater than 10
• Wilson's disease
• Known glycogen storage disease
• Vascular lesions (vasculitis, cardiac sclerosis, acute or chronic Budd-Chiari, hepatoportal sclerosis, peliosis)
• Polycystic liver disease
• Other metabolic or congenital liver disease
• Evidence of systemic infectious disease
• Known HIV positive
• Disseminated or advanced malignancy
• Any other condition, which in the opinion of the investigator would impede compliance or hinder completion of study

Laborértékek
