Autoimmune Diseases and Vitamin D

Vitamin D could prevent rheumatoid arthritis – but much higher doses may be required in already–affected sufferers. New research reveals┬áthe so-called 'sunshine supplement' strengthens the immune system, which helps to prevent the body from attacking healthy cells and causing autoimmune conditions, such as arthritis.

Low levels of calcium or vitamin D, which is more important in systemic lupus erythematosus patients? An extensive data analysis. Calcium levels may play a significant role in the SLE disease process, more than originally thought, since SLE patients are at a higher risk for hypocalcaemic events.

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.

Low vitamin D level is not associated with increased incidence of rheumatoid arthritis (RA). Vitamin D levels were not associated with the development of RA in this patient population with matched controls. PubMed, Rheumatol Int, 2014 Apr 19. (Also see Rheumatoid Arthritis)

Vitamin D May Ease Fibro Pain. Patients who think they are deficient in the nutrient should consult their doctor first, experts say. WebMD, 01/17/2014. (Also see Fibromyalgia)

Deficiencies of Vitamin D

Association between serum vitamin D levels and neuropathic pain (NP) in rheumatoid arthritis (RA) patients: A cross–sectional study. Although further research is needed to clarify the association between serum vitamin D levels and NP, our study raises awareness of the need to screen for vitamin D deficiency in RA patients with NP.

Vitamin D Deficiency Linked More Closely to Diabetes than Obesity. Vitamin D deficiency and obesity interact synergistically to heighten the risk of diabetes and other metabolic disorders. Journal of Clinical Endocrinology & Metabolism, 02/23/2015. (Also see Prevention of Diabetes)

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

How Sunlight Affects Your Mental Health. A new study suggests just how much sunlight really matters to our emotional and mental health, more than any other weather phenomenon. Time Healthland, 11/07/2016.
