The Role of microRNA-210 in Regulating Oxidative Stress in Patients With PAD

MicroRNA-210 (miR-210) can be a potential therapeutic target of patients with peripheral artery disease (PAD). Recent evidence suggests the role of miR-210 and oxidative stress in the pathophysiology of PAD and its association with mitochondrial function, oxidative metabolism, walking distances and quality of life. The protocol evaluates the mechanisms which miR-210 regulates oxidative stress and provides evidence of potential therapeutic strategies.

About this study

The investigators will randomize 180 PAD patients that undergoing a revascularization operation in two groups: (1) an endovascular procedure or (2) an open bypass procedure. They are also planning to recruit 50 non-PAD healthy control subjects.

The goal is to answer the main hypothesis that miR-210 gene expression is a master regulator of oxidative stress and is associated with mitochondrial dysfunction, oxidative metabolism, walking function and quality of life.

Who can participate

Healthy volunteers accepted: Yes

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • male or female 30 years or older,
  • Infrainguinal PAD,
  • critical limb ischemia, defined as arterial insufficiency with gangrene, nonhealing ischemic ulcer, or rest pain consistent,
  • candidate for both endovascular and open infra-inguinal revascularization as judged by the vascular surgeons,
  • absence of musculoskeletal (most commonly arthritis related) or neurologic (most commonly back pain and sciatica related) symptoms,
  • willingness to comply with protocol, attend follow-up appointments, complete all study assessments, and provide written informed consent.

Exclusion criteria

  • life expectancy of less than 2 years due to reasons other than PAD,
  • acute lower extremity ischemic event secondary to thromboembolic disease or acute trauma,
  • current chemotherapy or radiation therapy

Treatment and study plan

Revascularization operation

Procedure

Participants will be randomized into an endovascular or open bypass procedure.

Control Group

Other

Healthy non-PAD participants will be recruited for the study.

Primary outcomes

  1. miR-210 gene expression

    Time frame: Change from baseline to six-month follow-up

    Measure miR-210 gene expression at baseline and after intervention

  2. Calf muscle biopsy biochemical measures

    Time frame: Change from baseline to six-month follow-up

    A skeletal muscle sample will be obtained from the gastrocnemius muscle.

Secondary outcomes

  1. Six-minute walk performance

    Time frame: Change from baseline to six-month follow-up

    Participants walking up and down a 100 foot hallway for six minutes following a standardized protocol. The goal is for them to walk as far as possible in six minutes

  2. Graded treadmill walk performance

    Time frame: Change from baseline to six-month follow-up

    Participants walking on treadmill following a standardized protocol. The goal is for them to walk as far as possible while the treadmill incline increases every 2 minutes.

  3. The 36-Item Short Form questionnaire (SF-36)

    Time frame: Change from baseline to six-month follow-up

    This well validated quality of life measure will be used to assess changes in patient perceived quality of life. The SF-36 is scored from 0-100, with 100 being the best score.

  4. The Walking Impairment Questionnaire

    Time frame: Change from baseline to six-month follow-up

    The well validated Walking Impairment Questionnaire (WIQ) will be used to measure patient- perceived walking performance. The WIQ is scored from 0-100, with 100 being the best score.
