A great many medical groups, like this one, have not completely figured out why vitamin D is so low and why it helps so much
They want to continue to delay treating until they are abolutely sure why it works
Seems like there are many other treatments which are widely used but not fully understood.
Wonder why they are delaying Vitamin D so much

Beyond its role in calcium and phosphorus metabolism for healthy bone mineralization, there is increasing awareness for vitamin D contribution in modulation of immune reactions. Given that ankylosing spondylitis (AS) is a chronic inflammatory disease involving excess immune/inflammatory activity and posing great therapeutic challenges, it is conceivable to claim that vitamin D treatment may be a safe and effective treatment to influence or modify the primary disease and its related comorbidities. Nevertheless, consistent body of research supporting this hypothesis is still lacking. In this paper, we examine whether systematic screening and treatment for vitamin D deficiency are feasible at present. We will review the immunomodulatory role of vitamin D and its contribution in initiation and progression of AS, as well as how they would determine the occurrence of comorbid conditions.

Our conclusion is that despite the overwhelmed interest about vitamin D treatment in AS patients, systematic screening and treatment for vitamin D deficiency of all AS patients are not feasible as yet. This stresses the need for further extensive well-designed research to prove vitamin D efficacy in AS beyond bone protection. And if utility is proven, personalized treatment regimes, duration of treatment, and threshold values for vitamin D should be provided.

Seems like 23 interactions of AS with Vitamin D are understood


Other health problems which are currently screened for low vitamin D (from the PDF)

"These include patients with

  • underlying conditions
    rickets, osteomalacia, osteoporosis, chronic kidney disease, hepatic failure, malabsorption syndromes, hyperparathyroidism, granuloma-forming disorders, and some lymphomas
  • taking medications that interact with vitamin D metabolism
    antiseizure medications, glucocorticoids, AIDS medications, ketoconazole, and cholestyramine),
  • obese subjects,
  • pregnant and lactating women, and
  • older adults with history of falls or nontraumatic fractures as well as
  • African-American and Hispanic adults and children "
