Vitamin D status and psoriasis duration: is there a link?

Psoriasis is a chronic, inflammatory disease that causes the life cycle of skin cells to accelerate. This results in red, thickened patches of skin that itch or burn. Psoriasis is not contagious, and this condition comes and goes over time.

Currently, there is no cure for psoriasis. Treatment involves medication that slows down skin cell growth. Unfortunately, many of these treatments are costly and can cause a variety of side effects. Therefore, scientists have begun looking into ways to help manage psoriasis naturally. In a new study, researchers evaluated the relationship between vitamin D status and psoriasis.

A total of 170 psoriasis patients, 51 patients with autoimmune bullous and 340 healthy control were included in the analysis. Autoimmune bullous is a rare skin condition that causes fluid filled blisters to appear on the skin. All participants had their vitamin D levels measured, and the season this measurement took place was recorded.

Research findings:

  • Vitamin D levels differed significantly between all three groups (p = 0.0001).
  • Patients with autoimmune bullous had the lowest average vitamin D levels at 18.2 ng/ml.
  • Those with psoriasis had significantly lower 25(OH)D levels than health controls (21.8 ng/ml vs. 34.3 ng/ml; p = 0.007).
  • Of the patients with psoriasis, 45.8% were vitamin D deficient (defined as levels < 20 ng/ml) and 38.9% were insufficient (20-30 ng/ml).
  • Vitamin D deficiency was inversely associated with psoriasis duration (p = 0.038).

The researchers concluded,

“These results confirm the reduced vitamin D levels in psoriatic patients when compared to healthy controls, and provide new evidence regarding the association of vitamin D levels and psoriasis duration.”
