Brief Summary

Arterial wall inflammation has been consistently suggested to serve a causal role in promoting atherosclerosis and predisposing to hard cardiovascular outcomes. Therefore, there is a global trend in the pharmaceutical industry to develop safe and effective anti-inflammatory agents that could lessen arterial wall inflammation and prevent its detrimental impact on atheroma growth and instability. To this end, autophagy has emerged as a key regulator of inflammation and dysfunctional autophagy machinery has been consistently reported as a contributing factor to atherosclerosis and inflammation. Trehalose, a natural disaccharide sugar found extensively among miscellaneous organisms, by preventing protein denaturation plays various protective roles against stress conditions. Numerous studies indicated trehalose's ability to induce macrophage autophagy-lysosomal biogenesis and reduce inflammation. Also, intravenous (IV) administration of trehalose showed beneficial effects in the reversal of atherosclerosis in atherosclerotic animals. Therefore, in this study, the investigators will explore the potential efficacy of IV trehalose administration on arterial inflammation by employing an positron emission tomography (PET) with 18F-labeled fluoro-2-deoxyglucose (18F-FDG) and computed tomography (18F-FDG PET/CT) technique which noninvasively characterizes vascular inflammation and atherosclerosis.

Study Arms (2)

Trehalose

EXPERIMENTAL

Participants will be received intravenous trehalose infusion weekly (15 g/week) for a period of 12 weeks

Drug: Trehalose

Placebo

PLACEBO COMPARATOR

Participants will be received equal volume of normal saline weekly for a period of 12 weeks

Drug: Normal saline

Interventions

Trehalose is a natural disaccharide sugar found extensively among miscellaneous organisms including bacteria, plants, insects, yeast, fungi, and invertebrates. By preventing protein denaturation, it plays various protective roles against stress conditions such as heat, freeze, oxidation, desiccation and dehydration. Owing to this capacity, trehalose is an FDA-approved pharmaceutical excipient that is used as a stabilizer in numerous medicines including parenteral products. In this study, all injections will be conducted by a trained nurse in the presence of a specialist physician at a duration of 45-90 minutes.
