Brief Summary

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

Participants in this study will be randomized to receive either oral vitamin D pills OR ultraviolet light treatment. The investigators will compare how these two methods of raising vitamin D levels will affect cholesterol levels.

Detailed Description

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

Potential subjects will be screened for eligibility, including serum 25(OH)D levels \<20ng/ml. Eligible subjects will be randomly assigned to receive either: 1) oral vitamin D3, 50,000 units weekly for 8 weeks or 2) narrow-band UVB radiation, 2 treatments/wk for 8 weeks. Duration of treatment will be based on skin type. After 8 weeks, 25(OH)D levels will be measured monthly. For participants with levels \<35 ng/ml, additional doses of oral vitamin D3 or UV radiation will be administered.

A subset of participants from both groups will participate in a skin biopsy cohort, where skin biopsies are obtained before and after 8 weeks of treatment.

Study Groups

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

Oral Vitamin D3

Participants will receive oral vitamin D3 50,000 units weekly for 8 weeks. If 25(OH)D levels remain \<35 ng/ml, subjects will receive additional doses of oral vitamin D.

Group Type ACTIVE_COMPARATOR

Oral Vitamin D3

Intervention Type DIETARY_SUPPLEMENT

50,000 units orally, each week x8 weeks; supplemental doses of 50,000 units orally, each month thereafter as needed

Ultraviolet Light

Subjects will receive 16 treatments with ultraviolet light (narrow band UVB) over 8 weeks. If 25(OH)D levels remain \<35 ng/ml, subjects will receive additional doses of narrow band UVB.

Group Type ACTIVE_COMPARATOR

Ultraviolet Light

Intervention Type RADIATION

16 treatments, 2-3 times weekly over 8 weeks; initial dose 45-75 seconds, whole-body exposure except face and groin, increasing by 10% as tolerated, to a maximum of 4.5 minutes
