25-Hydroxyvitamin D deficiency is associated with increased aortic stiffness in patients with systemic lupus erythematosus
OBJECTIVE To determine the relationship between serum vitamin D and markers of subclinical cardiovascular disease (CVD) in patients with SLE. METHODS We recruited SLE patients (≥ 4 ACR 1997 criteria) from outpatient clinics between January 2007 and January 2009. Vitamin D deficiency was defined as serum 25(OH)D <20 ng/ml measured by ELISA. Disease activity was measured using the SLEDAI-2K sco...
متن کاملHigher 25-hydroxyvitamin D is associated with lower relapse risk in multiple sclerosis.
OBJECTIVE A protective association between higher vitamin D levels and the onset of multiple sclerosis (MS) has been demonstrated; however, its role in modulating MS clinical course has been little studied. We investigated whether higher levels of serum 25-hydroxyvitamin D (25-OH-D) were associated with a lower risk of relapses in people with MS. METHODS We conducted a prospective cohort stud...
متن کاملDepression is associated with decreased 25-hydroxyvitamin D and increased parathyroid hormone levels in older adults.
CONTEXT Depression has incidentally been related to altered levels of 25-hydroxyvitamin D [25(OH)D] and parathyroid hormone (PTH), but this relation has never been studied systematically. OBJECTIVE To determine in a large population-based cohort whether there is an association between depression and altered 25(OH)D and PTH levels. DESIGN Population-based cohort study (Longitudinal Aging Stu...
متن کاملLow 25-hydroxyvitamin D is associated with increased mortality in female nursing home residents.
CONTEXT Vitamin D deficiency contributes to skeletal diseases and is highly prevalent among institutionalized elderly patients. Whether low 25-hydroxyvitamin D (25[OH]D) concentrations are an independent risk factor for mortality in these patients is, however, unclear. OBJECTIVE We aimed to evaluate whether 25(OH)D concentrations are associated with mortality. DESIGN, SETTING, AND PARTICIPA...
متن کاملTanning is associated with optimal vitamin D status (serum 25-hydroxyvitamin D concentration) and higher bone mineral density.
BACKGROUND Vitamin D is made in the skin on exposure to solar radiation, and it is necessary to optimal skeletal health. Subjects who use a tanning bed that emits ultraviolet B radiation (290-315 nm) are likely to have higher 25-hydroxyvitamin D [25(OH)D] concentrations than do subjects who do not regularly use a tanning bed. OBJECTIVE The first objective of this study was to ascertain whethe...
