Ankylosing spondylitis disease activity and serum vitamin D levels: a systematic review and meta-analysis

Abstract

Review question / Objective: Through a meta-analysis of case-control studies and cross-sectional research on AS, we examined the relationship between blood vitamin D levels and disease activity in order to establish the rationale for using VD as a therapeutic adjunctive treatment for AS. Rationale: It has not been established previously that serum Vitamin D (VD) levels and important monitoring indicators of disease activity in patients with ankylosing spondylitis (AS) correlate.
