NASH Treatment Approaches:

Now and in the Future


Outline
• Current Best Practices in NASH
Management
– Lifestyle Changes
– Pharmacologic
– Surgical Management Strategies
• Investigational Therapies
– Phase III
– Phase II
Lifestyle Changes in NAFLD
• Foundation of any treatment plan
• Difficult to achieve and sustain
• Not enough for morbidly obese pts
Percentage of Weight Loss
Associated With Histological
Improvement
Weight loss ≥ 10% in NAFLD
• Analysis of data from 4 randomized

studies

Weight loss ≥ 7%
NASH resolution
(64% to 90% of pts)*

Weight loss ≥ 5%
Ballooning/inflammation

Weight loss ≥ 3%
Steatosis
(35% to 100% of pts)*

*Depending on degree of weight loss.

Effect of Diet in NAFLD
• Limiting total caloric intake is ideal and
more important than aiming for a specific
nutrient composition
• My diet recommendation: limit processed
carbs!
– White/brown bread, rice
– White/orange potatoes
– Flour/corn tortillas
Hannah WN, et al. Dig Dis Sci. 2016;61:1365-1374. Slide credit: clinicaloptions.com
– Pizza/pasta
Effect of Exercise on NAFLD
• Physical inactivity linked to
– Increased body weight
– Central adiposity
– Insulin resistance
– Increased risk of metabolic syndrome
– NAFLD
– Severity of NASH

Exercise by METs
Physical Activity METs
Light intensity <3
•Sleeping
•Watching TV
•Writing, desk work, typing
•Walking, 1.7 mph (2.7 km/h), level ground, strolling, very slow
•Walking, 2.5 mph (4 km/h)
Moderate intensity 3 to 6
•Bicycling, stationary, 50 watts, very light effort
•Walking, 3.0 mph (4.8 km/h)
•Calisthenics, home exercise, light or moderate effort, general
•Walk, 3.4 mph (5.5 km/h)
•Bicycling, < 10 mph (16 km/h), leisure, to work or for pleasure
•Bicycling, stationary, 100 watts, light effort
Vigorous intensity >6
•Jogging, general
•Calisthenics (eg, pushups, sit-ups, pullups, jumping jacks), heavy, vigorous effort
•Running/jogging in place

Lack of Exercise Is Common in
NAFLD
• Pts engage in less physical activity
– < 20% meet recommended physical activity
guidelines
• Adults with NAFLD (N = 813)[1]
– 54% of pts reported NO physical activity
– Vigorous-intensity exercise (≥ 6 METs for 75
min/wk) associated with decreased odds of
NASH
• OR: 0.65 (95% CI: 0.43-0.98; P = .04)
1. Kistler KD, et al. Am J Gastroenterol. 2011;106:460-468. Slide credit: clinicaloptions.com
What Is the Right Prescription for
Exercise in Pts With NAFLD?
• Data limited by small sample sizes, poor
statistical power, and lack of correlation
with histopathology
• Exercise associated with a reduction in
hepatic fat even in the absence of weight
loss
• Small studies suggest resistance training
reduces hepatic fat, improves other
metabolic
Hashida R, parameters
et al. J Hepatol. 2016;[Epub ahead of print]. Slide credit: clinicaloptions.com
Evidence for Exercise in NAFLD
• No head-to-head trials of aerobic exercise
vs resistance training for efficacy in
NAFLD
– No data to suggest superiority of one exercise
regimen vs another
• Current evidence

My Recommendation

Hypocaloric diet Moderate


Sustained
(daily reduction
by 500-1000 kcal)
+ intensity = weight loss

Why Not Empirically Treat
Suspected NASH With Vitamin
E?
• ~ 50% of pts do not respond to vitamin E
[1]

– Liver enzymes are not reliable to assess quiescence or


progression
• Increased risk of hemorrhagic stroke[2]
• Prostate cancer risk?
– Absolute increase 1.6/1000 PY; synthetic form[3]
– No effect on prostate cancer risk (n = 11,000)[4]
• Long-term safety?
– Remains unknown though likely safe
