King Edward Medical University96 enrolled

Overview

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a spectrum of hepatic disease ranging from fat accumulation in liver to fibrosis and cirrhosis. It affects 25% of the world population on average. Objective of this study is to compare the effect of metformin (1000 milligrams daily) versus pioglitazone (30 milligrams daily) in improving liver transaminases and ultrasound changes in non-diabetic patients of NAFLD when given for six months. METHODS: A Quasi-experimental study was conducted in Mayo Hospital Lahore from October 2019 to November 2020.Out of 96 half Patients were assigned randomly to Group-A (metformin) or Group-B (pioglitazone). Demographic history, abdominal ultrasound \& liver enzymes were recorded on Proforma monthly till 6 months. Data was put into and analyzed by SPSS version 26; t-test was used to compare the mean liver transaminases between the two groups. Ultrasound findings were compared by Chi square. The P value of less than 0.05 was counted as significant.

Outcomes

Primary Outcomes

Liver transaminase levels

There should be a 22% or more change in transaminases levels from baseline.

Time frame: The comparison is done after 6 months of drug treatment

Secondary Outcomes

Fatty Liver Grade

There should be a change of liver fat content determined by ultrasound as Fatty Liver Grade
