From the Guidelines
The best treatment for hepatic fibrosis in this 55-year-old man with type 2 diabetes (HbA1c 7.8%), on metformin alone, obesity (BMI 38), and steatohepatitis with F3 fibrosis without cirrhosis is weight loss of 10%. Weight loss is the cornerstone of treatment for non-alcoholic steatohepatitis (NASH) and has been shown to improve liver histology, including fibrosis regression 1. A weight loss of at least 7-10% is typically needed to achieve significant improvement in fibrosis, with greater benefits seen with more substantial weight loss. This approach addresses the underlying pathophysiology by reducing fat accumulation in the liver, decreasing insulin resistance, and attenuating inflammatory processes that drive fibrosis progression.
Key Considerations
- Weight loss should be achieved through lifestyle modifications, including a hypocaloric diet and regular physical activity 1.
- A minimum weight loss goal of 5%, preferably 10%, is needed to improve liver histology, with fibrosis requiring the larger weight reduction to change 1.
- The Mediterranean diet has the best evidence for improving liver and cardiometabolic health 1.
- Both aerobic and resistance training improve NAFLD in proportion to treatment engagement and intensity of the program 1.
Additional Recommendations
- Patients with NAFLD should be evaluated for coexisting metabolic conditions, such as obesity, diabetes mellitus, hypertension, dyslipidemia, and cardiovascular disease, and these comorbidities should be managed aggressively 1.
- Statin therapy should be initiated or continued for cardiovascular risk reduction as clinically indicated, as it appears to be safe in adults with type 2 diabetes and NASH, including in the presence of compensated cirrhosis 1.
From the Research
Treatment Options for Hepatic Fibrosis
The treatment for hepatic fibrosis in a 55-year-old man with type 2 diabetes (T2D) and an HbA1c of 7.8%, who is taking Metformin, has obesity with a body mass index (BMI) of 38, and steatohepatitis with stage F3 fibrosis without cirrhosis, includes:
- Lifestyle modifications, such as weight loss through dietary modification and lifestyle change, which remains the mainstay of therapy 2, 3
- Pharmacological management, including:
- Pioglitazone, which has shown to significantly improve liver histology in patients with T2DM and NASH 4
- Vitamin E, which may improve histology in NASH, but its use is limited due to safety issues 2, 5
- Novel agents, such as obeticholic acid, which has shown significant histological improvements in steatohepatitis and fibrosis 2
- Other agents, such as liraglutide and pentoxiphylline, which have shown some success in non-diabetic patients with NASH 4
Considerations for Treatment
When considering treatment options, it is essential to:
- Diagnose and treat comorbidities, such as cardiovascular disease, which remains a primary cause of death in patients with NASH 2
- Monitor the patient's response to treatment and adjust the therapy as needed
- Consider the potential benefits and risks of each treatment option, including the use of vitamin E, which may improve clinical outcomes in patients with NASH and bridging fibrosis or cirrhosis, but may also increase the incidence of cardiovascular events 5
Emerging Therapies
Several emerging therapies are being developed for the treatment of NASH, including:
