简要总结
The main objective of this randomised pilot study is to explore the relative efficacy of dietary MLCT oil versus LCT oil (corn oil) in augmenting therapy of overweight and obese NAFLD patients with at least a 1-stage reversal between F1 and F4.
详细描述
The hypothesis of the study will be that daily intake of MLCT oil is more effective than corn oil in improving either NAFLD or NASH phenotype, with a greater reduction in liver fibrosis stage of participants with NASH.
The single-centre trial is a 2-arm, randomized pilot study with stratification by BMI. Up to 30 participants with biopsy/imaging proven NAFLD / NASH would undergo blinded 1:1 allocation to either control or test group.
All participants would be offered biopsy, whereby a repeat liver biopsy would be undertaken at the end of the study (6 months) to investigate the efficacy of dietary MLCT versus corn oil in augmenting therapy of NASH.
Dietary counselling for the participants will be provided by NUH dietician on 6 weekly basis on how to adhere to the required dietary regimen. For the first 12 weeks, participants are to consume only the 3 provided RTE meals (breakfast, lunch and dinner), with additional fruits or low calories snacks to be advised by dietician. During the second 12-week experimental period, participants will follow strict dietary guideline under the recommendation of the NUH dietician and have oil-containing products [chocolate sauce / oatmeal biscuits] with 30 g of corn or MLCT oil per day.
During the 6 months, study participants would be followed up at 0, 3, 6, 9, 12, 18 and 24 weeks. During each of the follow up visit, the participant would have blood drawn, urine and stool collected as per study schedule.
