  • HbA1c level≥ 7 % through the previous six months.
  • BMI between 19 og 35.
  • Specific inclusion criteria for type 2 diabetes:
  • Either treatment with metformin, sulfonylureas, dipeptidyl peptidase IV (DPP IV) inhibitors or glucagon-like peptide 1 (GLP-1) analogs.
  • Treatment with insulin and insulin in the combination with metformin, sulfonylureas, DPP IV inhibitors or GLP-1 analogs.

Who cannot join

  • HbA1C > 10%
  • Pregnancy.
  • Metal implanted at both ankles and wrists.

This is a multicenter trial involving the University Hospitals of three major danish cities: Aalborg, Aarhus and Odense. The trial is of cross-sectional design and consists of examinations including:

  • Blood samples to analyze bone markers, glycemic state, kidney function and sex-hormones.
  • 24 hour urine sample to analyze bone markers and kidney function.
  • Bone scans including dual energy x-ray absorptiometry (DXA) and high resolution peripheral quantitative computed tomography (HRpQCT) to evaluate Bone Mineral Density, t-score and bone structure.

Participants:

100 type 1 diabetics and 100 type 2 diabetics recruited from outpatient clinics at Aalborg, Aarhus and Odense, general practitioners and flyers.

Read the detailed description

Diabetes Mellitus and Osteoporosis are common conditions. Patients with Diabetes Mellitus are known to have more fractures than their non-diabetic counterparts. However bone mineral density (BMD) which is the most commonly used measure of fracture risk seems to be insensitive in diabetes, thus BMD is lowered in type 1 diabetes but not enough to explain an almost seven fold in fracture risk. BMD is increased in type 2 diabetes although they still have an increased fracture risk.

The investigators investigate this paradox in diabetes by assessing type 1 and type 2 diabetes patients bone status by blood- and urine samples (assessing markers of bone- and glycemic state) and two types of bone scans comprising of DXA and HRpQCT scan.

The diabetes mellitus patients are recruited from outpatients clinics in the three study sites (Aalborg, Aarhus and Odense) as well as general practitioners and by flyers and adds.

What is being measured

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

  1. HbA1c

    Long term blood glucose evaluation

    Measured: Baseline

  2. Bone Mineral Density (t-score)

    Measured: Baseline

Secondary outcomes (8)
  1. Biochemical Bone Markers

    Measured: Baseline

  2. Sex-hormones

    Measured: Baseline

  3. Electrolytes

    Measured: Baseline

  4. Vitamin D (25ODH /1,25OHD)

    Measured: Baseline

  5. Results from the HRpQCT scan including Trabecular and Cortical state

    Not available for participants at center Aalborg

    Measured: Baseline

  6. Markers of fat tissue and glycemic status

    Including Insulin level, adiponectin

    Measured: Baseline

  7. Verterbral fracture assessment

    A part of the DXA if vertebral fracture assessment is available. For patients at center Aalborg this will be evaluated through X-ray.

    Measured: Baseline

  8. Lifestyle and Medical history

    Assessed by structured interview and questionnaire. Information on alcohol consumption, smoking, pharmaceutical use, diabetes complications, diabetes duration, physical activity, previous fractures are collected.

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

An observational study of Diabetes Mellitus and Osteoporosis, run by Jakob Starup Linde at 2 sites in Denmark.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 28 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

HbA1c (time frame: Baseline). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01870557, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 May 2015.
