Vascular Regenerative Cell Exhaustion in Adults with Peripheral Artery Disease (PAD-VRCE)

Recruiting now

Conditions studied: Peripheral Vascular Diseases, Cardiovascular Disease, Type 2 Diabetes, Peripheral Artery Disease

In brief

PAD-VRCE is an observational, cross-sectional, two arm study aimed at determining if the presence of peripheral artery disease (PAD) can influence the number of circulating regenerative cells in blood. From peripheral blood samples, circulating progenitor cell content will be assessed via flow cytometry and compared between individuals with PAD and individuals without PAD. Ultimately, this study plans to evaluate the relationship between PAD, vascular regenerative cell exhaustion and overall cardiovascular health.

Who can join

Age: 18 and older, up to 80. Sex: any. Healthy volunteers: accepted.

You may qualify if…

Adults ≥18 and ≤80 years of age who meet either of the following criteria:
Clinically significant/symptomatic PAD (defined as symptomatic claudication with and an ankle brachial index of less than 0.85).
No history of PAD.
Willing and able to provide written informed consent and comply with study procedures.

You may not qualify if…

Unable or unwilling to provide written informed consent or to provide a peripheral blood sample.
Any life-threatening disease expected to result in death within two years.
Any malignancy not considered cured (except basal cell carcinoma of the skin). An individual is considered cured if there has been no evidence of cancer recurrence for the five years prior to screening.
Uncontrolled hypertension.

Active infectious disease requiring systemic antibiotic or anti-viral agents.
Known acquired immunodeficiency syndrome, such as Human Immunodeficiency Virus.
On oral steroid therapy (e.g. prednisone or other corticosteroids) or other immunosuppressive agents (e.g. methotrexate).
Treated autoimmune disorders
