BACKGROUND Obesity is associated with hypovitaminosis D. Whether body mass index (BMI) determines the replacement dose of vitamin D to achieve sufficiency is unclear. OBJECTIVE To determine the relationship between BMI and serum 25-OH vitamin D concentrations and whether the increase in serum 25-OH vitamin D concentrations with vitamin D replacement is dependent on BMI. METHODS Retrospectiv...
OBJECTIVES To review the relationships between vitamin D status and systemic lupus erythematosus (SLE) concerning immunological, clinical aspects and possible effects of supplementation in disease modulation. METHODS The literature was reviewed up to January 2017 for studies regarding the epidemiology, pathogenesis, immunological aspects, clinical implications and supplementation strategies. ...
BACKGROUND The presence of hypovitaminosis D in patients with autoimmune bullous skin diseases, such as pemphigus vulgaris (PV) and bullous pemphigoid (BP), is debated. In a previous study we found an increased prevalence of vertebral fractures (VFx) and hypovitaminosis D in PV and BP patients. The present study extends the sample size of the previous one, for investigating the 25-hydroxyvitami...
Alzheimer's disease (AD) is characterized by extracellular plaques in the brain, mainly consisting of amyloid-β (Aβ), as derived from sequential cleavage of the amyloid precursor protein. Epidemiological studies suggest a tight link between hypovitaminosis of the secosteroid vitamin D and AD. Besides decreased vitamin D level in AD patients, an effect of vitamin D on Aβ-homeostasis is discussed...
Dietary reference intakes (DRIs) for Vitamin D (VitD) have been traditionally established based on plasma 25-OHD concentration sufficient to prevent rickets and osteomalacia. While nutritional rickets is still prevalent in developing countries, hypovitaminosis D is becoming widespread around the world regardless the latitude. Emerging evidence has unravelled the physiological roles of VitD beyo...
