Safety Data in Patients with Autoimmune Diseases during Treatment with High Doses of Vitamin D3 According to the "Coimbra Protocol".

Serum 25-hydroxyvitamin D levels in patients with skin diseases including psoriasis, infections, and atopic dermatitis.

In routine serum samples of 1,532 patients from the previous 12 months we identified retrospectively 180 (mean age 49.
