M, et al. – This study tested the hypothesis that Aged Garlic Extract
(AGE) may improve endothelial function, oxidative stress, vascular
inflammation and insulin resistance in high risk cardiovascular subjects
with type 2 diabetes. In this group of type 2 diabetic patients at high
cardiovascular risk, 4 weeks treatment with AGE did not significantly
improve endothelial function, vascular inflammation, oxidative stress or
insulin resistance.
Methods
- A double blind, placebo controlled cross-over pilot study was performed in 26 subjects with type 2 diabetes who received 1200mg of AGE or placebo daily for 4 weeks with a 4 week washout period.
- Plasma HsCRP was measured as a marker of inflammation.
- Plasma TAOS,blood GSH/GSSG and plasma LHP were measured as markers of oxidative stress/anti-oxidant defence.
- Insulin resistance was measured using the HOMA-IR method.
- Endothelial function was measured using change in the reflective index (RI) post salbutamol using digital photoplethysmography and urinary albumin/creatinine ratio was measured as a biochemical surrogate.
- Measurements were taken at baseline and after intervention with AGE or placebo.
Results
- Of the 26 patients studied (Male 17, Female 9), age was 61 ± 8 yrs (mean ± 1 SD), HbA1c 7.2 ±1.1%, BP 130/75 ±15.9/9.8 mmHg , total cholesterol 4.2 ±0.81mmol/l, triglyceride 2.11 ± 1.51mmol/l, HDL-cholesterol 1.04 ± 0.29mmol/l.
- The majority of patients were being treated with metformin (59%), aspirin (50%) and statin (96%) therapy. 36% were treated with an ACEI.
- There were no changes in these therapies throughout the study.
- Treatment with AGE had no significant effect upon the above metabolic parameters including insulin resistance.
- Treatment with AGE also had no significant effect on markers of endothelial function (plethysmography), oxidative stress (TAOS, GSH/GSSG, LHP) or inflammation (HsCRP).
