Why the study?

Does aspirin at different doses improve markers of inflammation, oxidative stress, insulin resistance, and endothelial function in patients with type 2 diabetes?

Population

17 subjects with type 2 diabetes, mean age 57.4 years, 12 male (71%)

Comparison

Aspirin 75 mg/day, 300 mg/day, or 3.6 g/day for… vs Placebo for 2 weeks

Design

RCT, random, sequential, blinded

Follow-up

2 weeks per intervention

Key result

Aspirin at 75 mg, 300 mg, or 3.6 g daily for 2 weeks had no significant impact on markers of vascular inflammation, oxidative stress, insulin resistance, or endothelial function in type 2 diabetes.

Overview

Short-term aspirin lacks benefit on vascular or metabolic markers in type 2 diabetes; confirms neutral effects and challenges presumed pleiotropic actions.

Study Design

Type

RCT (n=17)

Blinding

Population
17 subjects with type 2 diabetes, mean age 57.4 years, 12 male (71%)
I
Intervention
Aspirin 75 mg/day, 300 mg/day, or 3.6 g/day for 2 weeks with a 2-week washout
C
Comparator
Placebo for 2 weeks
O
Outcome
Markers of vascular inflammation (sVCAM-1, Hs-CRP), oxidative stress (TAOS, FRAP, GSH), insulin resistance (HOMA), and endothelial function (photoplethysmography)surrogate

Short-term aspirin therapy at various doses does not significantly improve markers of vascular inflammation, oxidative stress, insulin resistance, or endothelial function in patients with type 2 diabetes.

Cite This Study

Raghavan et al. (2013) conducted an RCT in type 2 diabetes (n=17). aspirin vs. placebo was evaluated on markers of vascular inflammation, oxidative stress, insulin resistance and endothelial function. Aspirin at 75 mg, 300 mg, or 3.6 g daily for 2 weeks had no significant impact on markers of vascular inflammation, oxidative stress, insulin resistance, or endothelial function in type 2 diabetes.
