Description

In this Power Point lecture I discuss how to diagnose lupus using the new 2012 classification criteria by SLICC as well as the importance of vitamin D, light protection, not smoking, and preventing human papilloma virus infection in people who have systemic lupus erythematosus. To learn more about the causes and symptoms of lupus as well as its complications such as arthritis, Sjogren's syndrome, and fibromyalgia, go to and click on "Like" to get daily tips and facts at http://www.facebook.com/LupusEncyclopedia

- Low vitamin D levels - UV light - Smoking - Sulfa antibiotics

- White blood cell membranes have Vit D receptors - Higher prevalence of low Vit D in SLE patients - More severe SLE at presentation associated with lower Vit D - Lower Vit D levels occur during SLE flares - Low vitamin D correlated with flares

- Petri M et al, Vitamin D and SLE, Arthr & Rheum;65(7):1865-71 1006 patients, 128 weeks 25[OH]D < 40 ng/mL TX = 50,000 IU ergocalciferol (vit D2) + daily calcium with 200 IU vit D3 - - Results: - ≥ 20 ng/mL increase 25[OH]D associated with: - .22 decrease in SELENA/SLEDAI (P = .032) 21% decrease in having a SELENA/SLEDAI ≥ 5 Random urine/protein decreased by 2% (P = .0001) 15% decrease in odds of having urine/prot > .5

- Treat patients with 25[OH]D < 40 ng/mL - Aim for a level of around 40 ng/mL or higher

- Increased risk for lupus flares - Ask patients to include Bactrim and Septra in allergies

- Make sure all patients get yearly flu shot
