Nonalcoholic Fatty Liver Disease (NAFLD) Pharmacological Treatment: Metformin Versus Atorvastatin

Overview[ - collapse ][ - ]

Purpose The first line approach to NAFLD is currently based on diet and lifestyle modification. Aim of our Unit is to compare the efficacy of two different doses of metformin (1 g/day and 2 g/day) with atorvastatin (20 mg/day) on amelioration of inflammatory and cardiometabolic parameters, ultrasound signs and clinical scores associated with liver fibrosis in early-stage NAFLD non-diabetic patients.

Official TitleMetformin Versus Atorvastatin in Nonalcoholic Hepatic Steatosis: a Randomized Study
Brief Summary
The first line approach to NAFLD is currently based on diet and lifestyle modification. Aim
of our Unit is to compare the efficacy of two different doses of metformin (1 g/day and 2
g/day) with atorvastatin (20 mg/day) on amelioration of inflammatory and cardiometabolic
parameters, ultrasound signs and clinical scores associated with liver fibrosis in
early-stage NAFLD non-diabetic patients.
Detailed Description
Non alcoholic fatty liver disease (NAFLD) is a common liver disease that encompasses both
simple steatosis and non alcoholic steatohepatitis (NASH.

There is currently no therapy that is of proven benefit for these liver disorders both of
which are closely associated with insulin resistance and features of the metabolic syndrome
such as obesity, hyperlipidaemia and type 2 diabetes mellitus. The first line approach to
NAFLD is currently based on diet and lifestyle modification. However, dietary treatment is
limited by the lack of compliance and the frequent regain of weight at follow-up.

Aim of our Unit is to compare the efficacy of two different doses of metformin (1 g/day and
2 g/day) with atorvastatin (20 mg/day) on amelioration of inflammatory and cardiometabolic
parameters, ultrasound signs and clinical scores associated with liver fibrosis in
early-stage NAFLD non-diabetic patients.

The investigators will enrol obese or overweight non-diabetic patients with ultrasonographic
diagnosis of hepatic steatosis at early stage (NAFLD). The investigators will exclude from
the study patients with clinical-biochemical and ultrasound markers of disease severity
(age, BMI, lipid profile, AST, ALT, Angulo, BAAT and HAIR clinical fibrosis scores, signs of
portal hypertension and posterior attenuation of the deep liver parenchyma at US). Patients
who meet all eligibility criteria will be randomly assigned to one of three groups for 12
months of study treatment. The first group (n=50) will receive metformin (1g/day) plus
dietary treatment; the second group (n=50) will be given metformin (2 g/day) and the third
group (n=50) will be treated with atorvastatin (20 mg/day). All participants will be
followed-up at 3, 6, 9, 12 months intervals after randomization. We will compare the effects
of two doses of metformin with atorvastatin on the amelioration of both inflammatory (PCR,
TNF-a , IL-6) and metabolic parameters (lipid profile, BMI, waist circumference, fasting
glucose, 2-h glucose tolerance test, insulin, transaminases, adiponectin,leptin, HOMA-IR
index and VAI index). Furthermore, we will assess the improvement under drug treatment of
liver steatosis on the basis of US signs (liver echogenicity and stiffness) and of fibrosis
scoring systems (Angulo, BAAT and HAIR scores).

In conclusion, considering the increasing prevalence of NAFLD and its strong association
with cardiovascular diseases and cancer, the investigators expect to identify a safe
pharmacological regimen that, in addition to dietary treatment, may ameliorate or even
reverse this liver disease and the underlying risk factors. This study could have an
important social impact in terms of both preventive and therapeutic interventions.
