Autoimmune Diseases and Vitamin D

Vitamin D, disease activity and comorbidities in early spondyloarthritis. In early axial spondyloarthritis vitamin D deficiency was associated with higher disease activity and severity and presence of metabolic syndrome. PubMed, Clin Exp Rheumatol, 04/05/2016. (Also see Ankylosing Spondylitis)

How a daily supplement could guard against HIV: Vitamin D. High doses of vitamin D may be able to stave off HIV infections, scientists believe. Mail Online, 06/18/2015.

Vitamin D status in rheumatoid arthritis (RA) patients: relation to clinical manifestations, disease activity, quality of life (QoL) and fibromyalgia syndrome (FMS). Special attention is required regarding vitamin D levels in RA patients with FMS and decreased QoL. Vitamin D should be corrected and supplementation considered among the RA management armamentarium.

Scleroderma and Vitamin D Deficiencies

Systemic Sclerosis Patients Found to Have Low Vitamin D Levels, Reduced Bone Mineral Density & Total Mineral Content. Findings suggest that skin thickness in SSc patients could be one factor in determining low circulating levels of vitamin D that in turn could play a significant role in the reduction of bone mineral density and total mineral content. Scleroderma News, 09/23/2015.

Vitamin D receptor (VDR) regulates TGF–ß signalling in systemic sclerosis (SSc). Impaired VDR signalling with reduced expression of VDR and decreased levels of its ligand may thus contribute to hyperactive TGF–ß signalling and aberrant fibroblast activation in SSc. Ann Rheum Dis, 2015;74:e20.

Sunshine Exposure and Protection

Sunbathers take heed: skin damage continues hours after exposure. Here's a warning to sunbathers everywhere. Scientists have found that the skin damage caused by UV rays does not stop once you get out of the sun. Reuters, 02/19/2015.
