Relation Between Plasma Vitamin K2 and Glycemic Control and Metabolic Parameters in Type 2 Diabetic Patients.
Background and Rationale:
The agents inducing type 2 diabetes are yet to be clarified. Current studies show that several genetic and environmental parameters are associated with type 2 diabetes . Vitamin K is emerging as an important micronutrient for its beneficial role in improving insulin sensitivity and glucose metabolism and reducing the risk of type 2 diabetes (T2 D) . Studies demonstrated the lowest prevalence of Metabolic syndrome and its five components among individuals with the highest phylloquinone intake.
Objectives : The aim of our study was to evaluate the relation between plasma vitamin K2 and uncontrolled Type 2 diabetic patients.

Detailed Description
The frequency of diabetes mellitus is increasing globally and it is expected that this latent disorder will affect 300 million by 2025. Type 2 diabetes mellitus (T2DM) is a metabolic and chronic disease characterized by hyperglycemia representing the major cause of various micro and macrovascular complications
The agents inducing type 2 diabetes are yet to be clarified; however, it has been suggested that diabetes is an immune-dependent disease . Current studies show that several genetic and environmental parameters are associated with type 2 diabetes .
Vitamin K is a fat soluble vitamin . Two vitamin K- dependent-proteins, osteocalcin and matrix gamma carboxy glutamate (Gla ) protein, present in skeletal and vascular system , vitamin K exists mainly in two biologically active forms: vitamin K1 (also known as phylloquinone) and vitamin K2 (also known as menaquinone) .
According to current studies, vitamin K2 has a wider range of effects besides coagulation and functioning as a cofactor for γ--glutamate carboxylase (GGCX ) . The effect on bone is to prevent and treat osteoporosis and the effect on the cardiovascular system is to prevent and treat vascular calcification.
study by Sogabe N et al ., reported an important role of vitamin K in the regulation of dyslipidemia and vitamin K2 treatment delayed the progression of atherosclerotic plaque formation, intima-thickening, and pulmonary atherosclerosis.
study by Dam V et al ., demonstrated the lowest prevalence of Metabolic syndrome and its five components among individuals with the highest phylloquinone intake. Among the five components of Metabolic syndrome , an increase in dietary phylloquinone intake was significantly associated with a decrease in the prevalence of elevated blood pressure and reduced HDL cholesterol .
Vitamin K is emerging as an important micronutrient for its beneficial role in improving insulin sensitivity and glucose metabolism and reducing the risk of type 2 diabetes (T2 D) .
The effect of vitamin K supplementation on insulin sensitivity and glycemic status has been reviewed by study by Manna et al . They integrated currently available evidences and proposed that both vitamin K1 and vitamin K2 supplementation were beneficial to the reduced risk of T2DM. This also suggests a beneficial role of vitamin K2 on insulin sensitivity and glucose metabolism.
studies by (Yan Li et al ., 2018 - Prasenjit Manna And Jatin Kalita , 2016 ) provided an overview of the currently available studies to assess the effect of vitamin K2 supplementation on insulin sensitivity, glycaemic control and reviewed the underlying mechanisms. Overall, carboxylation of vitamin K-dependent protein osteocalcin, anti-inflammatory property, regulation of adipokine levels and lipid-lowering effect were three mechanisms underlying vitamin K2 reduced risk of T2DM and vitamin K2 had a better effect than vitamin K1 on T2DM. The interpretation of this review will increase comprehension of the development of a therapeutic strategy to prevent and treat T2DM.
Objectives:
The aim of our study was to evaluate the relation between plasma vitamin K2 and uncontrolled Type 2 diabetic patients.
Patients and methods:
A case control study including 90 subjects aged 20 to 65 years, 30 healthy subjects as a control group and 60 patients with type 2 DM .Patients will be collected from the endocrinology outpatient clinic, Kasr El Ainy, Cairo university. Patients will be divided into 3 groups, (group I) 30 patients with uncontrolled type 2 DM, (group II) 30 controlled type 2 DM and (group III) 30 non DM as control group.
All subjects will be consented and then subjected to full history taking emphasizing on the age , duration of diabetes mellitus and its treatment and full clinical examination including blood pressure measurement, weight, height, BMI (kg/m2) and waist circumference .
Laboratory investigations : in the form of fasting blood glucose (FBG), 2 hr postprandial blood glucose (2 hr -PPG), fasting lipids {total cholesterol (TC), triglycerides (TAG), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C)}, glycosylated hemoglobin (Hb A1c) and Vitamin K 2 levels will be assessed .
laboratory methodology: Two milliliters of peripheral venous blood were collected after 8 hour fasting from each participant. The measurement of Vit K2 was achieved by commercial ELISA kit based on its protocol (Glory science Co., Ltd: U.S.A.).
-Study outcomes:
Primary outcomes :
- Relation between plasma vitamin K2 and glycemic control in Type 2 diabetic patients.
- Relation between plasma vitamin K2 and metabolic parameters in Type 2 diabetic patients.
Secondary outcome parameters :
- Relation between plasma vitamin K2 and disease duration in Type 2 diabetic patients.
- Relation between plasma vitamin K2 and forum of antidiabetic treatment in Type 2 diabetic patients.
