About this study

Official title: Evaluation of Immunologic Response After Vitamin D Supplementation in Patients With Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disorder. It mainly involves the skin, the joints, the nervous system and the kidney and may be life threatening.

SLE is associated with production of autoantibodies and perturbations in regulatory T cells and T helper lymphocytes producing interleukin (IL)-17 (Th17 cells).

Treatments include corticosteroids, hydroxychloroquine and immunosuppressive agents.

Immunomodulatory effects of vitamin D supplementation in VITRO was recently described, notably the expansion of Treg able to suppress inflammatory responses mediated by CD4+ and CD8+ T cells and the decrease of Th17 cells.

Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disorder. It mainly involves the skin, the joints, the nervous system and the kidney and may be life threatening.

SLE is associated with production of autoantibodies and perturbations in regulatory T cells and T helper lymphocytes producing interleukin (IL)-17 (Th17 cells).

Treatments include corticosteroids, hydroxychloroquine and immunosuppressive agents.

Immunomodulatory effects of vitamin D supplementation in VITRO was recently described, notably the expansion of Treg able to suppress inflammatory responses mediated by CD4+ and CD8+ T cells and the decrease of Th17 cells.

Objective : To evaluate the cellular immune response after vitamin D supplementation in patients with SLE.

Methods : This is an open prospective trial. SLE patients with hypovitaminosis D (< 30 ng/mL) receive vitamin D supplementation. 100 000 UI of cholecalciferol per week for 4 weeks then 100 000 UI of cholecalciferol per month for 6 months will be administered. All patients are followed after the beginning of vitamin D supplementation at month 2 and month 6.

End points :

  1. Clinical and biological tolerance: Absence of hypercalcemia or lithiasis during and after vitamin D supplementation.
  2. Immunologic follow-up of T cells and B cells homeostasis (including Treg and Th17) and gene expression profile in PBMCs using TRANSCRIPTOMIC analysis, before, during and after vitamin D supplementation.
  3. Clinical efficacy: follow-up of clinical manifestations of SLE and disease activity score (SLEDAI) during and after vitamin D supplementation.

Schedule : Duration of patients' inclusion period is estimated 3

Questions about this trial

What is this clinical trial studying?

An observational study of Vitamin D Deficiency, run by Assistance Publique - Hôpitaux de Paris at 3 sites in France.

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 3 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 24 Nov 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in France. 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?

Immunologic follow-up of T cells and B cells homeostasis (including regulatory T cells and Th17 cells) and gene expression profile of PBMCs using TRANSCRIPTOMIC analysis, before, during and after vitamin D supplementation (time frame: 6 months). 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 24 Nov 2011.
