Systemic lupus erythematosis and vitamin D deficiency are associated with shorter telomere length among African Americans, according to a study published last week in PLOS ONE.
Systemic lupus erythematosis (SLE) is a chronic autoimmune disorder resulting in tissue damage and inflammation. SLE can harm the heart, lungs, skin, joints, blood vessels, liver, kidneys, and nervous system. SLE is most common in African American women. Vitamin D deficiency is thought to be a potential environmental trigger of SLE and SLE linked disease expression. Patients with SLE often avoid the sun, a common trigger of disease flair, so the risk of vitamin D deficiency is high among people with SLE.
