The benefits of raising HDL cholesterol levels in patients with type 2 diabetes remains uncertain. Some of the statin trials suggest that statin therapy eliminates some of the excess risk from low HDL cholesterol levels in patients with LDL cholesterol elevation at baseline.

The Veterans Administration HDL Intervention Trial (VA-HIT) showed an approximately 22% reduction in CHD events in patients with diabetes and known CHD when HDL cholesterol levels were increased by approximately 6% by gemfibrozil. [354] This was a population with low LDL cholesterol levels, however, so whether these same benefits would accrue in patients with elevated LDL cholesterol who are treated with a statin before their low HDL cholesterol is addressed is unclear.
