Bone health, vitamin D and lupus

Abstract

The prevalence of vitamin D deficiency and insufficiency among patients with systemic lupus erythematosus is high. This is likely due to photoprotection measures in addition to intrinsic factors of the disease. Low levels of vitamin D increase the risk of low bone mineral density and fracture. Vitamin D deficiency could also have undesirable effects on patients' immune response, enhancing mechanisms of loss of tolerance and autoimmunity. Vitamin D levels should be periodically monitored and patients should be treated with the objective of reaching vitamin D levels higher than 30-40 ng/ml.
