Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this observational study is to evaluate muscle fiber type composition in people with type 2 diabetes mellitus (T2DM) with a common complication of T2DM: diabetic peripheral neuropathy (DNP), specifically diabetic sensorimotor polyneuropathy. Researchers will also look into factors related to DNP: inflammation, the use of energy in the cell, nerve function and the tiny blood vessels in the muscle.

The main question it aims to answer is: Are there differences in muscle fiber type composition between persons with T2DM with and without DNP, in comparison to sex and age-matched healthy peers?

Participants will partake in the following tests:

* electromyoneurography (EMNG): evaluation of nerve function, damage and repair; for diagnosis of DNP or other diseases of the nerves
* blood analysis: researchers will measure insulin, blood sugar, lipid profile, inflammation
* muscle biopsy in the calf (m. gastrocnemius): a doctor will take a small sample of muscle to evaluate the muscle shape and structure
* mechanography: patients will perform functional tests (e.g. standing up from a chair), researchers will evaluate maximal power and maximal force of the muscles by jumping tests
* questionnaires: on food intake, physical activity, smoking history, alcohol use, medical history
* measurement of height, weight, and the comparison of the hip and waist circumference
* peripheral Quantitative Computed Tomography (pQCT): scan of the calf for muscle density and bone density
* electrocardiography (ECG): evaluation of electrical signals of the heart

Researchers will compare (1) patients with T2DM with DNP, (2) patients with T2DM without DNP, and (3) healthy persons to see if there are differences in muscle fiber type composition

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

T2DM DNP+

type 2 diabetes with diabetic neuropathy

Blood sampling

Intervention Type DIAGNOSTIC_TEST

Fasting blood samples will be obtained.

Electromyoneurography (EMNG)

Intervention Type DIAGNOSTIC_TEST

Nerve conduction of sensory and motor nerves of the upper and lower limb will be performed, including F- and H-waves. Needle EMNG of the m. tibialis anterior, m. gastrocnemius (medial head), m. tensor fascia lata and m. gluteus maximus) will be performed.

Muscle biopsy

Intervention Type PROCEDURE

Muscle biopsy of the m. gastrocnemius will be performed under local anesthesia using the modified Bergström technique.

Quantitative peripheral computed tomography (qPCT)

Intervention Type RADIATION

A qPCT scan of the calf will be performed.

Mechanography

Intervention Type DEVICE

Single two leg jump, multiple one leg hopping, chair rise and sit to stand tests will be performed.

Electrocardiography (ECG)

Intervention Type DIAGNOSTIC_TEST

A 15-minute resting ECG will be performed.

Questionnaires

Intervention Type OTHER

Questionnaires will be performed to collect information on medical background (drug use, comorbidities, symptoms of peripheral neuropathy, ...) and lifestyle factors (ethyl consumption, food intake, physical activity, smoking).

Anthropometry

Intervention Type OTHER

Length and hip:waist ratio will be measured. Furthermore, body weight and composition will be determined by bio-impedance measurement. Systolic and diastolic blood pressure (mean of 3 times) will be evaluated.
