OBJECTIVE Vitamin D deficiency is common in patients with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). Whether vitamin D levels are further lowered in patients with concomitant IPAA and primary sclerosing cholangitis (PSC) is not known. The aim of this study was to evaluate the presence of PSC as a risk factor for vitamin D deficiency in patients with UC and IPAA. METHODS ...

Vitamin D deficiency is a preventable health problem. Vitamin D deficiency among pregnant women is frequent in many populations over the world. Research indicates that adequate vitamin D intake in pregnancy is optimal for maternal, fetal and child health. Adverse health outcomes during pregnancy are preeclampsia; gestational diabetes mellitus and caesarean section. Consequences in newborns are ...

The concentration of total vitamin B12 in serum is not a sufficiently sensitive or specific indicator for the reliable diagnosis of vitamin B12 deficiency. Victor Herbert proposed a model for the staged development of vitamin B12 deficiency, in which holotranscobalamin (HoloTC) is the first indicator of deficiency. Based on this model, a commercial immunoassay has been controversially promoted ...

INTRODUCTION Vitamin D deficiency is highly prevalent and is associated with bone disease, cardiovascular disease, metabolic syndrome and malignancy. Injection drug users (IDUs), with or without HIV infection, are at risk for these conditions; however, limited data on vitamin D deficiency exist in this population. We determined the prevalence and correlates of vitamin D deficiency among urban I...

BACKGROUNDS Vitamin D deficiency is common worldwide, including Iran. It has been suggested that vitamin D deficiency is associated with non-specific musculoskeletal pain. The aim of this study is evaluation of the association of musculoskeletal pain with vitamin D deficiency and the response of the patients to vitamin D supplementation. MATERIALS AND METHODS Sixty two adult patients with chi...

The immune system is critical in preventing infection and cancer, and malnutrition can weaken different aspects of the immune system to undermine immunity. Previous studies suggested that vitamin B6 deficiency could decrease serum antibody production with concomitant increase in IL4 expression. However, evidence on whether vitamin B6 deficiency would impair immune cell differentiation, cytokine...

background and objectives: vitamin d deficiency/insufficiency is a global health problem. the importance of this problem is doubled in growing children because of their increased need for skeletal growth. this investigation was performed firstly to assess vitamin d status, and secondly to examine its possible relationship with sex, residing area and duration of sun exposure in 9-12 years old ch...

INTRODUCTION We compared the odds of vitamin D deficiency in three chronic diseases: systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), and type 2 diabetes (T2DM), adjusting for medications, demographics, and laboratory parameters, common to all three diseases. We also designed multivariate models to determine whether different factors are associated with vitamin D deficiency in dif...

Systemic lupus erythematosus (SLE) is a complex multi-system autoimmune disease. Vitamin D deficiency has been proposed as an environmental trigger of disease onset and as a contributor to increased SLE activity. SLE patients are prone to develop vitamin D deficiency because of photosensitivity leading to sun avoidance and other sun protective measures. The impact of vitamin D on immune functio...
