Treatment of Vitamin D Deficiency in Intestinal Rehabilitation Clinic Patients With a Portable Ultraviolet B Lamp
A study testing Ultraviolet B lamp in people with Vitamin D Deficiency and Short Bowel Syndrome, run by University of Nebraska at 1 site in United States.
Trial summary
This is a randomized, controlled, unblinded pilot study for patients with vitamin D deficiency in Intestinal Rehabilitation clinic. These patients are not able to absorb oral vitamin D efficiently and thus have a high prevalence of vitamin D deficiency, leading to low bone density. Read more about this study

About this study
This is a randomized, controlled, unblinded pilot study for patients with vitamin D deficiency in Intestinal Rehabilitation clinic. These patients are not able to absorb oral vitamin D efficiently and thus have a high prevalence of vitamin D deficiency, leading to low bone density.
The investigators will use FDA approved portable Ultraviolet B lamp for the intervention group, 11 patients will be recruited from October 2013 to end of January 2014 and study period is 12 weeks for each patient. Study completion will be end of April 2014.
Study hypothesis: Ultraviolet B light with a portable ultraviolet device will increase Total 25 hydroxy vitamin D level in Intestinal Rehabilitation Clinic patients.
Read the detailed description
Vitamin D plays an integral role in bone metabolism and is one of the principal hormonal regulators of calcium and phosphorus absorption in the body. In 2011, the Endocrine Society defined Vitamin D deficiency as a 25 hydroxy vitamin D below 20 ng/ml and vitamin D insufficiency as a 25 hydroxy vitamin D of 21 ng/ml to 29 ng/ml.Without vitamin D, only 10 to 15% of dietary calcium and about 60% of phosphorus is absorbed.
Intestinal Rehabilitation clinic at University of Nebraska Medical Center includes patients with short bowel syndrome, multiple abdominal fistulae, and altered GI motility.
Hypovitaminosis D is associated with increased parathyroid hormone secretion,increased bone turnover, osteoporosis, histological osteomalacia and increased risk of hip and other fractures, and, in its most severe expression,clinical osteomalacia. These patients have been given high doses of both oral vitamin D2 and vitamin D3 supplementation without an improvement in vitamin D status due to poor intestinal absorption . Standardized treatment of vitamin D deficiency in most healthy individuals is achieved by giving vitamin D2 50,000 IU once a week for few weeks and then daily supplementation with lower doses. In the investigators Intestinal rehabilitation clinic, these patients are vitamin D insufficient or deficient while on large replacement doses of vitamin D2/D3 with some taking 200,000 IU daily.
It has been reported that irradiation with Ultraviolet B can be used safely and effectively to treat vitamin D deficiency among vitamin D deficient patients. Exposure of the body in a bathing suit to 1 Minimum Erythemal Dose (MED) of sunlight is equivalent to ingesting about 10,000 IU to 25,000 IU of vitamin D. Thus, exposure of 6% to 10% of the body surface to 1 MED is equivalent to ingesting about 600 to 2500 IU of vitamin D. Although ultraviolet irradiation can be achieved from exposure to sunlight, it is generally available only seasonally and difficult for persons who are too ill to spend much time outdoors. Ultraviolet-Fluorescent lamp (KBD, Inc, Crescent Springs, Kentucky,USA) was designed to use ultraviolet B emitting fluorescent bulbs that have lower heat emission and allows a larger area of skin exposure. The Lamp is equipped with a timer for improved safety. This device is FDA (Food and Drug Administration) approved.
Baseline labs include 25 hydroxy D, intact parathyroid hormone and complete metabolic profile. Patients will receive a 3 minute skin exposure to Ultraviolet B light and if they do not develop a sun burn, they will be randomized to Control or Ultraviolet B light group. Patients will continue their current dose of Vitamin D2/D3 for 12 weeks in both groups.Ultraviolet B light will be administered in 3 different areas on the same day for 5 minutes each, once a week at a distance of 14 inches wearing an UV eye shield. Areas of skin exposure will be based on rule of nine for body surface area which includes back, abdomen, thighs, and arms.
Patients will get blood draws at baseline and 12 weeks to monitor response to Ultraviolet B light. If Ultraviolet B light is able to increase total 25 hydroxy vitamin D level, it can potentially be used at home by these patients after receiving basic training and instructions.

| Study group | Role | What they receive |
|---|---|---|
| Ultraviolet B lamp | Experimental | Intervention arm: Patients in the Ultraviolet B lamp group will continue vitamin D2/D3 daily and will receive 3 treatment sessions of Ultraviolet B light once a week for 12 weeks.

Ultraviolet B light sessions will be supervised and conducted by study personnel or Center for Clinical and Translational Research staff. A food questionnaire will be reviewed at each visit to assess dietary intake of calcium. Skin exam will be conducted at the beginning and end of the session. Receives: Device: Ultraviolet B lamp |
| Control | No intervention | Patients in control group will continue with their current dose of Vitamin D2/D3 for 12 weeks.Patients will remain on the same steady dose for the duration of the study.These patients will not receive Ultraviolet B light sessions. |
What is being measured
The primary outcome is the main question the study is designed to answer.
25 Hydroxy Vitamin D Levels
Our hypothesis is that Ultraviolet B light with a portable Ultraviolet device will increase Total 25 hydroxy vitamin D level in Intestinal Rehabilitation Clinic patients.
We will measure serum level of 25 hydroxy vitamin D at baseline and 12 weeks to monitor the response of Ultraviolet B exposure administered by the portable Ultraviolet B lamp.
Measured: 12 weeks
Secondary outcomes (1)
Serum Intact Parathyroid Hormone Level
Hypovitaminosis D is associated with increased Parathyroid hormone secretion (inversely related to 25 hydroxy D), increased bone turnover, osteoporosis, histological osteomalacia and increased risk of hip and other fractures, and, in its most severe expression,clinical osteomalacia.
Measured: 12 weeks

Questions about this trial
What is this clinical trial studying?
A study testing Ultraviolet B lamp in people with Vitamin D Deficiency and Short Bowel Syndrome, run by University of Nebraska at 1 site in United States.
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 3 inclusion and 14 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 4 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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?
Yes. Results are posted in the registry (first posted 25 Aug 2023). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
25 Hydroxy Vitamin D Levels (time frame: 12 weeks). 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 NCT01930539, which also lists 9 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 4 Oct 2023.
