About this study

Official title: Effect of Electroacupuncture on Sensitive Symptoms of Distal Diabetic Peripheral Neuropathy and Its Correlation With Nerve Conduction Changes

This is a controlled clinical trial with the aim to study the effects of electroacupuncture on neuropathic pain reduction, quality of life and changes in sensory and motor nerve conduction velocity in patients with type 2 diabetes mellitus, beneficiaries of the familiar medical centers 20, 40 and 41 of the Instituto Mexicano del Seguro Social, at north of Mexico City, in colaboration with the human acupuncture specialty of the Escuela Nacional de Medicina y Homeopatía, Instituto Politécnico Nacional, Mexico.

Read the detailed description

Controlled clinical trial to evaluate the effect of electroacupuncture on the reduction of neuropathic pain, quality of life; electrophysiological, inflammatory response, oxidative stress, and genetic expression, in patients with type 2 diabetes mellitus, beneficiaries from the family medical centers 20 , 40 and 41 of the Instituto Mexicano del Seguro Social, at north of Mexico City.

Once the acceptance letter has been signed, a series of questionnaires (MNSI, MDNS, DN-4, NRS, and SF-36), and a physical examination will be carried out to meet the necessary criteria to continue participating.

Only candidates with clinical diagnosis of diabetic polyneuropathy will have an electrophysiological examination by nerve conduction velocity study, if so, patients will be randomized to the electroacupunture or sham acupuncture groups.

Before intervention, laboratory studies will be taken after fasting for 8 to 10 hours, to determine biochemichal profile (glucose, urea, creatinine, uric acid , triglycerides, total cholesterol, HDL and LDL), oxidative stress (Malondialdehyde), inflammatory response (IL-6, IL1β, TNF-α, IL-10 and IL-18 cytokines), and gene expression (5-HT1AR, Neurokinin 1, α-adrenoreceptors, NGF, CX3CR1, GAP-43, and NT3).

Intervention will be applied in a total of 32 acupuncture sessions, divided into two intervention cycles, that is, 16 sessions over two months, with a rest period of one month in between.

At the end of both cycles of interventions, the questionnaires, the nerve conduction velocity study the biochemical and molecular studies will be re-assessed. Finally, this will be re-evaluated after three months post-intervention in order to evaluate the effect of intervention over time.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ElectroacupunctureProcedure or surgery

    Also called EA

    Intervention consists of a total of 32 sessions, divided into two intervention cycles, that is, 16 sessions over two months, with a rest period of one month in between. EA is applied for 20 minutes at an alternating frequency of 2 Hz. Acupunctural points are Zusanli (E36), Fenlong (E40), Yinlingquan (B9), Sanyinjiao (B6), Taichong (H3) and Zulinqi (VB41).

  • Sham AcupunctureProcedure or surgery

    Also called Sham

    Intervention consists of a total of 32 sessions, divided into two intervention cycles, that is, 16 sessions over two months, with a rest period of one month in between. Sham acupuncture will be applied using a nonpuncture device without electrical stimulation at the same acupunctural points as in the EA group.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Nerve Conduction Velocity

    Measured by Nerve Conduction Velocity Study using the VIKING LIFE-SAVING EQUIPMENT, to determine Motor and Sensitive Nerve Conduction Velocity of common peroneal nerve, sural nerve, and tibial nerve.

    Sensitive Nerve Conduction (SCV). Distance between the receiving point and the stimulus point. SCV normal values: Peroneal nerve ≥ 41 m/s, tibial nerve ≥ 44 m/s, sural nerve ≥ 50 m/s.

    Motor Conduction Velocity (MCV). Distance between two points and the difference in incubation between them after superstimulation of the corresponding nerve branch. MCV normal values: Peroneal nerve ≥ 41 m/s, tibial nerve ≥ 44 m/s, sural nerve ≥ 60 m/s.

    *Values below those stipulated above indicate that NCV has slowed down, and is abnomal.

    The investigators expect a diminishment of SCV and MCV in sham acupuncture group from the first cycle of intervention whereas electroacupuncture group remains unchanged or even increases SCV and MCV.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

Secondary outcomes (8)
  1. Michigan Neuropathy Screening Instrument (MNSI).

    It will be assessed with a lower extremity examination by a health professional of both feet in search of deformities, dry skin, calluses, infections, fissures and ulcers. Complemented with measurement of vibratory sensation, ankle reflexes, and Semmes-Weinstein monofilament test.

    The investigators expect improvement in the physical aspect of the foot in the electroacupuncture group, while in the sham acupuncture group the complication progresses.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  2. Michigan Diabetic Neuropathy Score (MDNS)

    Composed of three items where the sensory compromise is evaluated with the perception of vibration, 10 gr. monofilament and pin prick, in addition to the muscular strength of the toes, and the bicipital, tricipital, quadriceps and achilles muscle reflexes. The investigators expect a diminishment of MDNS score and clinical improvement in the electroacupuncture group and progression of clinical manifestations in the sham group.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  3. Douleur Neuropathique en 4 Questions (DN-4)

    A screening tool for neuropathic pain consisting of 10 interview questions (DN4-interview) and physical tests. A score greater than 4 points suggests neuropathic pain. The investigators expect decreased scores in the electroacupuncture group and increased or persistent scores in the sham group.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  4. Numerical Pain Rating Scale (NRS)

    Patients are only asked to circle the number between 0 and 10, 0 and 20 or 0 and 100 that best matches the intensity of their pain currently and in the last 7 days, where zero usually represents "no pain", while the upper limit represents "the worst pain of their life". The investigators expect diminishment of rating scale in electroacupuncture group and an increase in sham acupuncture group.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  5. Quality life (SF-36)

    It will be measured by The Short Form-36 Health Survey (SF-36) a measure of health status that consists of eight scaled scores (vitality, physical functioning, bodily pain, general health perceptions, physical role functioning, emotional role functioning, social role functioning, and mental health), which are the weighted sums of the questions in their section. The investigators expect quality life improvement in electroacupuncture group while in sham acupuncture group might worsen.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  6. Oxidative Stress

    Determined by quantifying the concentrations of the lipoperoxidation product Malondialdehyde (MDA). An increase of MDA is expected in the sham group, while in the electroacupuncture group it is expected to decrease.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  7. Inflammatory response

    Assessed by changes in serum concentrations of proinflammatory (IL-6, IL1β, TNF-α and IL-18) and anti-inflammatory (IL-10) cytokines determined by quantitative ELISA by flow cytometry. The investigators expect increase of anti-inflammatory cytokine and decrease of proinflammatory cytokines in the electroacupuncture group, while in the sham group this is inversely presented.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.

  8. Genetic expression

    mRNA expression of 5-HT1AR, Neurokinin 1, α-adrenoreceptors, NGF (Nerve growth factor), CX3CR1, GAP-43 (Growth associated protein 43) and Neurotrophin (NT3), (Chemoline receptor 1) genes quantified by real-time PCR. The investigators expect an increase in gene expression in patients with electroacupuncture while in sham patients it is decreased or even unchanged.

    Measured: Baseline evaluation, after the first and second cycle of intervention, respectively, and three months after the end of the intervention.
