Project title

"Treatment with oral vitamin D in diabetic patients with chronic foot ulcers on the lower limb; a clinical controlled study of the effect on wound healing".

Abstract

Aims and objectives

The purpose of this study is to determine whether daily supplements of vitamin D improves wound healing in diabetic patients with chronic foot ulcers.

Background

Lifetime risk of developing chronic lower extremity ulcers summarized in type I and type II diabetics is about 25% and the prevalence is approximately 7%. There is often a long term resource consuming disorder where 47% of the diabetic leg and foot ulcers effectively can be treated within 12 months.

In Denmark in 2011 there were more than 300,000 diagnosed type I and type II diabetics, and estimated about 200,000 undiagnosed type II diabetics. Therefore, approximately 35,000 diabetics each year are treated for chronic leg or foot ulcers in the Danish health sector. The treatment of these chronic wounds are associated with significant costs, as well as emotional, physical and financial.

Vitamin D deficiency is a widespread problem, and it is estimated that worldwide there is 1 billion people suffering from vitamin D deficiency. A Danish study from 2012 showed vitamin D deficiency in 52% of adults aged 30 60 years. Vitamin D deficiency is more common in diabetics with chronic foot or leg ulcers, when compared with non diabetics and diabetics without ulcers.

Methods and materials

48 diabetic patients with chronic foot ulcers will be included in the study. The patients will be recruited from the outpatient clinic, department of orthopaedic surgery at Zealand University Hospital, Denmark. The patients will randomly be divided into two groups, respectively treated with vitamin D or placebo.

Expected outcome and perspectives

The investigators expect that this study will show that supplementation with oral vitamin D, will result in a significant effect on wound treatment and healing for a large group of diabetic patients with chronic foot ulcers. This will contribute to a changed procedure in this specific group of patients, leading to measurement of vitamin D status and supplementation with vitamin D if needed.

Questions about this trial

What is this clinical trial studying?

A study testing Vitamin D in people with Diabetic Foot Ulcers and Vitamin D Deficiency, run by Zealand University Hospital.

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 4 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: finished, as of the sponsor's last update on 23 Jan 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Wound healing (time frame: 48 weeks or wound healing.). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 23 Jan 2019.
