Objectives: To determine the prevalence of vitamin D deficiency in patients with small and medium vessel systemic vasculitis.
Methods: In this cross-sectional study, 25-hydroxy (OH) vitamin D3 levels were measured in adult patients with systemic small and medium vessel vasculitis including antineutrophil cytoplasmic antibody-associated vasculitis (AAV), cryoglobulinaemic vasculitis (CryV), IgA vasculitis (IgAV) and polyarteritis nodosa (PAN), and age- and sex-matched healthy subjects (HS) and patients with rheumatoid arthritis (RA) as control groups. 25OH vitamin D3 levels<30ng/ml and <20ng/ml were regarded as insufficiency and deficiency, respectively.
Results: Fifty-seven patients (42 AAV, 2 CryV, 8 IgA vasculitis, 5 PAN) with systemic vasculitis, 101 HS, and 111 RA patients were included. The mean 25OH vitamin D3 level was
- 21.8±14.2ng/mL in patients with vasculitis,
- 42.7±27.6ng/mL in HS (p<.001) and
- 20.1±18.47ng/mL in patients with RA (p=.54).
Vitamin D insufficiency and deficiency were significantly higher in patients with systemic vasculitis compared to HS (75.4% vs 33.7%, p<.001; %50 vs 21.8%, p<.001, respectively).
Vitamin D status was not different in patients with systemic vasculitis compared to RA. There was a negative correlation between vitamin D status and CRP levels (=-.364, p=.007).
The multivariate logistic regression analysis showed that renal involvement was significantly associated with vitamin D deficiency/insufficiency in patients with vasculitis (OR 22.5 [95% CI 1.6-128.9].
Conclusion: Vitamin D deficiency and insufficiency are more frequent in patients with systemic small and medium vessel vasculitis and RA than HS. Renal involvement is one of the factors associated with vitamin D deficiency/insufficiency in patients with vasculitis.

- FACT: The Kidneys are not the primary way to activate vitamin D; the tissues are
- FACT: When the Kidney has problems, there is less active vitamin D (Calcitriol) for the body
- FACT: When the Kidney has problems, there is increased death due to many factors - many of which are associated with lack of Calcitriol
- FACT: There are many ongoing intervention clinical trials trying to determine how much of what kind of vitamin D is needed to treat the problem
- FACT: One Randomized Controlled Trial has proven that Vitamin D treats CKD
- FACT: 38% of seniors have Chronic Kidney Disease and most are unaware of it CDC statistics 2020
- FACT: Taking extra Vitamin D, in various forms, does not cause health problems - even if poor kidney
- Suggestion: Increase vitamin D getting into body now - and increase co-factors so that the vitamin D can be better used
Sun, UV lamp, Vitamin D supplement - probably > 5,000 IU,
Nanoemulstion vitamin D (inside cheek, topically) gets activated Vitamin D to the cells without the need for healthy kidney, liver, or intestine
Calcitriol - which bypasses the need for the kidney to activate vitamin D
Problems with Calcitriol however: typically only lasts for a few hours, also, possible complications
Update: Pre-cursor of active vitamin D made from plants is better than calcitriol – Sept 2012 - Category Kidney and Vitamin D contains

Vasculitis on the web
Wikipedia March 2022
- "Vasculitis is a group of disorders that destroy blood vessels by inflammation.[2] Both arteries and veins are affected. Lymphangitis (inflammation of lymphatic vessels) is sometimes considered a type of vasculitis.[3] Vasculitis is primarily caused by leukocyte migration and resultant damage. Although both occur in vasculitis, inflammation of veins (phlebitis) or arteries (arteritis) on their own are separate entities."
- According to the size of the vessel affected, vasculitis can be classified into:[7][8]
- Large vessel: Takayasu's arteritis, Temporal arteritis
- Medium vessel: Buerger's disease, Kawasaki disease, Polyarteritis nodosa
- Small vessel: Behçet's syndrome, Eosinophilic granulomatosis with polyangiitis, Cutaneous vasculitis, granulomatosis with polyangiitis, Henoch–Schönlein purpura, and microscopic polyangiitis.
