Abstract
Background:
The purpose of this study was to investigate the safety and effects of Melissa officinalis, a good source of bioactive components, on apolipoprotein (Apo)B, Apo A-I, and their ratio, lipids ratios and intercellular adhesion molecule-1(ICAM-1) in patients with type 2 diabetes.
Methods:
For the present randomized, double-blinded, placebo-controlled clinical trial, 70 type 2 diabetic patients aged 20-65 years old were randomly assigned to receive hydroalcoholic extract of M. officinalis (HEMO) (700 mg/d) or placebo twice-daily for 12 weeks.
Results:
There were significant differences in serum Apo A-I, TC/ HDL-c and LDL-c/ HDL-c between the two groups at the end of the study (p < 0.05), but we did not show significant differences in the values for Apo B, Apo B/Apo A-I, TG/HDL-c, ICAM-1 and liver enzymes include AST, ALT, and ALP between the study groups. Although both groups showed a significant reduction in ICAM-1, AST and, ALP (p < 0.05), no significant differences in ICAM-1, AST and, ALP were observed. At end, in M. officinalis group, there was a significant increase in Apo A-I (p = 0.003) and significant reduction in TG/HDL-c (p = 0.05) compared with initial values, as well as in placebo group, there was a significant rising in Apo B/Apo A-I (p = 0.02) and significant reduction in Apo A-I (p = 0.001) compared with baseline values.
Conclusions:
M. officinalis is safe and effective in improvement of Apo A-I, Apo B/Apo A-I, and lipids ratios as key factors promoting cardiovascular disease (CVD) in type II diabetic patients.
