Rheumatoid arthritis disease activity and vitamin D deficiency in an Asian resident population

Abstract

We highlight the importance of skin exposure to sunlight in a conservative dressing culture. No association was observed between vitamin D and disease activity. However, the high prevalence of vitamin D deficiency may negatively impact on bone health of these patients in the future.

Inverse Relationship Between High Blood 25-Hydroxyvitamin D and Late Stage of Age-Related Macular Degeneration in a Representative Korean Population

“…[21][22][23] Several human studies have shown an inverse relationship between vitamin D and several chronic conditions associated with inflammation. [24][25][26][27] In the eye, vitamin D may prevent AMD progression via its antiinflammatory and antiangiogenic properties. 28 However, epidemiologic studies on the relationship between vitamin D and AMD have been limited, and the results are inconsistent.…”

The relationship between vitamin d level and disease activity in patients with rheumatoid arthritis

“…In addition, there was no significant relationship between duration of illness and serum 25 (OH) vitamin D level [14]. In a study with 35 patients in the United Arab Emirates, there was no significant correlation between serum vitamin D levels and disease activity score (DAS28) or HAQ scores [15]. In another study with patients with RA, a moderately significant negative correlation was found between serum 25 (OH) vitamin D level in active disease, pain, and number of sensitive joints and DAS28, but no significant correlation was found between parameters in the remission group [16].…”

Valuable verities on vitamin D

“…In a study performed by Quraishi et al . in RA patients from Dubai, mainly originating from the Indian subcontinent and of Arab origin, no association was found between disease activity and vitamin D levels; this finding may be explained by the fact that the disease was well controlled with DMARDs, mainly methotrexate …”
