Overall , the current meta- analysis demonstrated that ALA administration may lead to an improvement in glucose homeostasis parameters and lipid profiles except HDL-cholesterol levels
OBJECTIVE This systematic review and meta- analysis of r and omized controlled trials ( RCTs ) was performed to summarize the effect of alpha-lipoic acid ( ALA ) supplementation on glycemic control and lipid profiles among patients with metabolic diseases .
Impact of therapy with alpha-lipoic acid (ALA) on the oxidative stress in the controlled NIDDM: a possible preventive way against the organ dysfunction?
There is a growing evidence that excess generation of highly reactive free radicals , largely due to hyperglycemia , causes oxidative stress , which further exacerbates the development and progression of diabetes and its complications . The purpose of this study was to evaluate the impact of ALA on lipid profile , oxidative pattern and inflammation in patients with controlled non-insulin dependent diabetes mellitus ( NIDDM ) .  ALA , 400mg/day was investigated in NIDDM patients over a period of 4 weeks using a r and omized , placebo-(PLA)-controlled study with two parallel groups . The marker of oxidative stress was the concentration of reactive oxygen metabolites , evaluated using a commercially available test , called d-ROMs  test  , and the  biological antioxidant potential ( BAP ) ; besides , the lipid profile ( total cholesterol = TC , high-density lipoprotein-cholesterol = HDL-C ; low-density lipoprotein-cholesterol = LDL-C , and triglycerides = TG ) and the C-reactive protein ( CRP ) , marker of inflammation were measured at the beginning and at the end of the treatment . A total of 14 patients were r and omly assigned to the two groups . ALA was safe and well tolerated in the only oral daily administration . The d-ROMs test ( p=0.03 ) and HDL-C ( p=0.04 ) showed a significant difference between the two groups . BAP ( p=0.06 ) tended to be higher in the treated patients , while LDL-C ( p=0.07 ) presented a moderate decline . There were no significant differences in TC ( p=0.65 ) , TG ( p=0.78 ) and CRP ( p=0.96 ) between the ALA and PLA groups . ALA therapy appears to reduce significantly d-ROMs and to improve HDL-C value , especially in men with metabolic syndrome treated with oral hypoglycemic drugs . These findings will be useful in patient selection in future clinical trials with ALA in long term studies
