A Randomized Study to Compare the Efficacy of Vitamin E, Ursodeoxycholic Acid and Pentoxyfylline on Egyptian Patients With Non-alcoholic Fatty Liver Disease Using (IL6 and CCL2) as a Predictors of Non-alcoholic Steatohepatitis

This was a 3-month, prospective, randomized, and single blind study. Participants were recruited from the outpatient clinic and hepatology, gastroenterology and infectious diseases department at Kafrelsheikh University Hospital between February 2020 and January 2021. Two-hundred and five Egyptian patients diagnosed with NAFLD with potential clinical inclusion criteria were invited for a screening session to determine their eligibility for the study. Patients were enrolled in the study if they are > 18 years old, had evidence for NASH; persistently elevated alanine aminotransferase (ALT) >1.5 times the upper limit of normal), imaging (ultrasound) showing fatty infiltration, and histological evidence of NASH after biopsy (macrovascular steatosis, ballooning degeneration of hepatocytes, scattered lobular inflammation and apoptotic bodies).One hundred and forty-six patients were excluded from the study either because they did not meet the inclusion criteria (n = 135) or refused to enroll in the study (n =11). Qualifying participants (n = 102) were randomly assigned to one of the three treatment groups using a computer-generated randomization sequence. Group I (n = 34) received 400 IU Vitamin E (Vitamin E 400 IU®, MEPACO Pharmaceutical Company, Sharqia, Egypt) twice daily for 3 months. Group II (n =34) received 250 mg Ursodeoxycholic acid (Ursofalk 250 mg®, MINAPHARM Pharmaceutical Company, Cairo, Egypt) twice daily for 3 months. Group III (n = 34) received 400 mg sustained release (SR) Film-Coated Tablets of pentoxifylline (Trental 400 mg®, SANOFI Pharmaceutical Company, Cairo, Egypt) twice daily for 3 months. Patients were followed up every week to ensure compliance, drug adherence and to report side effects or drop out from the study.The following parameters were measured both before and after intervention intake; liver aminotransferases (AST, ALT), cytokine and chemokine (IL6 and CCL2/MPC-1), albumin, total bilirubin, direct bilirubin, total cholesterol, triglyceride, LDL, HDL.
