introduction: iron deficiency anemia (ida) is the most common form of anemia and one of the most important health problems. iron supplementation for high risk groups can prevent ida and its complications in the community. we need to have a holistic approach to control ida with minimum cost and complications. considering the high prevalence rate of ida in iran, assessment of the effects of micro...

Most vertebrates synthesize vitamin C (ascorbate) de novo from glucose, but humans and certain other mammals cannot. In this issue, Montel-Hagen et al. (2008) demonstrate that erythrocytes from these ascorbate auxotrophs switch the preference of their glucose transporter Glut1 from glucose to dehydroascorbate (DHA), the oxidized form of vitamin C. This substrate preference switch is mediated by...

BACKGROUND AND OBJECTIVES Vitamin D deficiency is reportedly common, but we lack data from young adults. Such data are of interest because epidemiological data support vitamin D as a possible risk modulator for diabetes and cardiovascular ('cardiometabolic') disease. Our objectives were to assess vitamin D status (as plasma 25(OH)D concentration) and investigate associations between this and bi...

Background Vitamin D deficiency is associated with physiologic changes that are similar to pathogenesis of preeclampsia. Although association of vitamin D and preeclampsia has been studied previously, their results are not consistent. The aim of this study was to investigate the relationship of serum vitamin D and calcium with preeclampsia severity. Materials and Methods: This case- control st...

Elevated serum alkaline phosphatase (ALP) is a screening marker for the diagnosis of vitamin D deficiency, which may fail to be diagnosed if serum ALP is not elevated. Here, we describe a case of vitamin D deficiency without elevation of serum ALP. A 1-year-old Japanese girl was referred to our hospital for the evaluation of genu varum. Her serum intact PTH level was elevated, while her serum A...

Vitamin D deficiency is considered as one of the most prevalent healthcare problems in the world. Vitamin D contributes to insulin synthesis and secretion. Deficiency of vitamin D leads to insulin resistance which is the major cause of type 2 diabetes mellitus. We aim to evaluate the effect of treating vitamin D deficiency or insufficiency on serum adiponectin, leptin, and leptin to adiponectin...

Scurvy is a potentially lethal condition caused by inadequate vitamin C intake. Hypovitaminosis of vitamin C causes vessel fragility and follicular hyperkeratosis that can lead to palpable purpuric skin lesions. In this case report, we aim to remind readers that scurvy still occurs in Western countries and that the clinical presentation may resemble vasculitis.

Background: Iron deficiency anemia is one of the major causes of morbidity and mortality worldwide. Evidences from epidemiological and clinical studies suggest a possible correlation between antioxidant levels and the anemic disease risk. The present work is to investigate antioxidant levels and lipid peroxidation in anemic patients. Methods: A number of 30 patients (15 males and 15 females) we...

Vitamins are organic compounds needed in minute amounts that are essential for life and must be absorbed from the gastro-intestinal tract. Either the vitamin must be in the diet (dietary essential) or be synthesized by microorganisms in the digestive system and absorbed by the host animal. Currently there are 14 recognized vitamins but not all animals require all 14 vitamins (Table 1). When an ...
