Brief Summary

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

Oxygen is required for an optimal muscle function. In patients with diabetes mellitus, hyperglycemia can cause vascular complications. The endothelium (inter layer of the blood vessels) can be damaged leading to a reduced oxygen flow towards the muscle cells. Besides, it is possible that mitochondrial dysfunction is occuring leading to reduced extraction of oxygen.

Both conditions will lead to a reduced flow of oxygen towards the muscle and this can have impact on the production of energy necessary for optimal functioning.

In this study, the investigators will examine the functionality of the blood vessels (1) and the uptake of oxygen into the muscles (2) in patients with diabetes mellitus type 1 and type 2 (with and without vascular complications) compared to healthy persons.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigators plan to recruit in total 125 participants who will be divided into 3 main groups: (I) diabetes mellitus type 1 (with (a) or without (b) vascular complications), (II) diabetes mellitus type 2 (with (a) or without (b) vascular complications), and (III) healthy persons. Diabetes mellitus will be defined by the guidelines of the American Diabetes Association (ADA).

The examinations for this study consist of a blood pressure assessment, Flow Mediated Dilatation (FMD)-measurement, and a handgrip exercise test. The protocol will take approximately 2 hours.

The investigator who performs the FMD-test followed a course and passed thorough evaluation.

The blood pressure assessment will be continuously for 20 minutes to avoid large bias.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

NA

Intervention Model

SINGLE_GROUP

Participants are divided into 3 groups based on their diagnosis: diabetes mellitus type 1, diabetes mellitus type 2, and healthy persons. Each participant (independent of group) will have the same examinations. There is no retesting of the same participant in other conditions.
Primary Study Purpose

OTHER

Blinding Strategy

NONE

There is no masking because the participant knows his diagnosis. Besides, the investigator checks the blood sugar at different times during the examinations, so also the investigator is not blinded. In this study, blinding would have no additional value.

Study Groups
