Background: The role of vitamin D in the pathogenesis of rheumatoid arthritis is under investigation. This study was designed to evaluate the correlation between serum values of 25(OH) vitamin D [25(OH)D] and disease activity in rheumatoid arthritis (RA) patients according to Disease Activity Score 28 joints and ESR (DAS28ESR). Methods: Ninety-nine patients according to ACR classification crit...

background: it seems that serum vitamin d levels are one of the potential environmental factors affecting the severity of multiple sclerosis (ms). in this study, we aim to evaluate vitamin d levels in ms patients and healthy subjects and assess the relationship between vitamin d level and disability. methods: in this case-control study, 168 rapid relapsing ms patients and 168 matched healthy co...

Vitamin D (VIT D) deficiency is determined by serum 25-OH-D. Several studies revealed high prevalence of VIT D deficiency in females of the Asian sunny countries. 162 females referred to Urmia Orthopedic Clinics, with bone and muscle pain with the ages 15 up to 40 yrs participated in the study. The individuals were not pregnant, lactating, with no systemic or neurological diseases during the co...

Methods: The prevalence of multiple sclerosis (MS) is high in patients suffering from 25-hydroxyvitamin D3 [25(OH)D] deficiency. The aim of this study was to investigate the possible association of saliva and serum 25(OH)D concentrations with MS in women.Methods: Serum and saliva 25(OH)D levels of 30 MS women and 30 matched healthy controls in this case-control study were measured by ELIS...

BACKGROUND There is increasing evidence that vitamin D deficiency is common and has been associated with several non-bone related outcomes, including insulin resistance, type 2 diabetes and cardiovascular disease. The influences of gender, puberty, and adiposity on serum hydroxyvitamin D (25-OH-D) levels and the relationship between 25-OH-D and insulin resistance in obese children were studied....
