Abstract
Objective There has been increasing research regarding the effects of vitamin D on autoimmune disorders. There is some evidence of a correlation between vitamin D levels and sicca symptoms. We attempted to evaluate the correlation between vitamin D levels and inflammation of the minor salivary gland (MSG). Methods Data for 214 patients who had undergone MSG biopsy were reviewed. Eighteen patients with other autoimmune/neoplastic processes were excluded. Seventy-seven of 196 patients had serum Vitamin D levels available and were selected for this retrospective study. Demographic, clinical, and immunological features, extra-glandular manifestations, autoantibodies, and clinical laboratory tests were collected and compared between patient groups with a focus score (FS) of 0 and 1 or more. Results Out of 77, 29 patients had an FS of 0 while 48 had an FS of 1 or more. Mean vitamin D levels were noted to be lower in patients with an FS of 1 when compared to patients with an FS of 1 or more. Conclusion In this study, patients with an FS of 1 were noted to have low vitamin D levels but this association was not seen at a higher FS.
