Effect of Vitamin D Supplementation on Hemoglobin A1c in Patients With Uncontrolled Type 2 Diabetes Mellitus

2014-08-27 03:19:03 | BioPortfolio

Summary

The purpose of this study is to determine if daily supplementation with 2000 International Units of Vitamin D will improve hemoglobin A1c in uncontrolled type 2 diabetics.

Description

Vitamin D is typically understood to support musculoskeletal health when administered concomitantly with calcium. A number of recent studies suggest, however, that this important nutrient may play a significant role in many pathophysiological processes, including diabetes mellitus. With the prevalence of diabetes mellitus ever increasing, novel mechanisms for controlling blood glucose and hemoglobin A1c are being sought to help prevent the costly and debilitating complications of this chronic disease.

Vitamin D C3-epimer levels are proportionally higher with oral vitamin D supplementation compared to ultraviolet irradiation of skin in mice but not humans.

A proportion of circulating 25-hydroxy vitamin D (25(OH)D) undergoes epimerization to form C3-epi 25(OH)D and C3-epi 1,25(OH)D. These epimers have less calcaemic activity than non-epimerized metabolit...

Medical and Biotech [MESH] Definitions

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.

A group of substances similar to VITAMIN K 1 which contains a ring of 2-methyl-1,4-naphthoquinione and an isoprenoid side chain of varying number of isoprene units. In vitamin K 2, each isoprene unit contains a double bond. They are produced by bacteria including the normal intestinal flora.

A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)

OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.

A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
