Acta Scientific Pharmaceutical Sciences (ISSN: 2581-5423) Volume 2 Issue 12 December 2018 Review Article Recent Insights into the Role of Vitamin B12 and Vitamin D upon Cardiovascular Mortality: A Systematic Review Raja Chakraverty1 and Pranabesh Chakraborty2* 1Assistant Professor, Bengal School of Technology (A College of Pharmacy), Sugandha, Hooghly, West Bengal, India 2Director (Academic), Bengal School of Technology (A College of Pharmacy),Sugandha, Hooghly, West Bengal, India *Corresponding Author: Pranabesh Chakraborty, Director (Academic), Bengal School of Technology (A College of Pharmacy), Sugandha, Hooghly, West Bengal, India. Received: October 17, 2018; Published: November 22, 2018 Abstract since the pathogenesis of several chronic diseases have been attributed to low concentrations of this vitamin. The present study Vitamin B12 and Vitamin D insufficiency has been observed worldwide at all stages of life. It is a major public health problem, throws light on the causal association of Vitamin B12 to cardiovascular disorders. Several evidences suggested that vitamin D has an effect in cardiovascular diseases thereby reducing the risk. It may happen in case of gene regulation and gene expression the vitamin D receptors in various cells helps in regulation of blood pressure (through renin-angiotensin system), and henceforth modulating the cell growth and proliferation which includes vascular smooth muscle cells and cardiomyocytes functioning. The present review article is based on identifying correct mechanisms and relationships between Vitamin D and such diseases that could be important in future understanding in patient and healthcare policies. There is some reported literature about the causative association between disease (CAD). Numerous retrospective and prospective studies have revealed a consistent, independent relationship of mild hyper- Vitamin B12 deficiency and homocysteinemia, or its role in the development of atherosclerosis and other groups of Coronary artery homocysteinemia with cardiovascular disease and all-cause mortality. -

The Reliability and Reproducibility of the Schilling Test in Primary Malabsorptive Disease and After Partial Gastrectomy
Gut: first published as 10.1136/gut.4.1.32 on 1 March 1963. Downloaded from Gut, 1963, 4, 32 The reliability and reproducibility of the Schilling test in primary malabsorptive disease and after partial gastrectomy J. F. ADAMS AND E. JUNE CARTWRIGHT From the Western Infirmary, Glasgow EDITORIAL SYNOPSIS A study of the reproducibility and reliability of the Schilling test in patients with primary malabsorptive disease and after partial gastrectomy is reported. The value of the test was assessed by repeated tests in each patient. Consistently normal or abnormal results were obtained in only one of the seven patients with primary malabsorptive disease and in only two of the eight patients who had undergone partial gastrectomy. From these results it is concluded that the result of a single test may be of little clinical value. Assessment of the results suggests that the mean value for a series of Schilling tests may give some indication of value clinically about the capacity to absorb radioactive vitamin B12 at the time of the tests at least in patients who have undergone partial gastrectomy. The significance of the findings is discussed, particularly in relation to the aetiology of post-gastrectomy megaloblastic anaemia. http://gut.bmj.com/ Absorption tests using radioactive vitamin B12 may ml. water; two hours later 1,000 ptg. vitamin B12 was given be of considerable value in establishing a precise intramuscularly and urine was collected for the subsequent diagnosis in conditions in which anaemia results 24 hours.

Injection Composition Each ampoule of 1 ml contains: Active Ingredient Cyanocobalamin (vitamin B12) 1000 micrograms/ml Other Ingredients Sodium acetate anhydrous, acetic acid glacial, water for injection. Mechanism of Action Vitamin B12 (cyanocobalamin) is essential for growth, cell reproduction, hematopoiesis, and nucleoprotein and myelin synthesis. It has many metabolic interrelationships with the basic nutrients. Its physiological role is associated with methylation, participating in nucleic acid and protein synthesis. Vitamin B12 (cyanocobalamin) is essential for folate utilization with functional folate deficiency resulting from its absence. Indications Pernicious anemia and its neurological complication, subacute combined degeneration of the spinal cord. Treatment of vitamin B12 deficiency states and macrocytic anemias associated with nutritional deficiencies, gastrectomy and abnormalities of, or malabsorption from, the gastrointestinal tract such as celiac disease, sprue and accompanying folic acid deficiency. Bedodeka is also suitable for use as the flushing dose in the Schilling Test for pernicious anemia. Contraindications Known hypersensitivity to vitamin B12, or to any other ingredient of the preparation. Bedodeka is not indicated for treatment of toxic amblyopias. Warnings An intradermal sensitivity test may be performed in patients with suspected hypersensitivity to cobalamins. It is important to accurately diagnose anemias prior to treatment, to ensure that appropriate therapy is initiated. -

She recently relocated from another state to be closer to her daughter, although she lives in her own “se- nior” apartment. Through history taking, you learn that she has a long history of osteoarthritis, mild hypertension requir- ing medication for the past 5 years, and occasional gastroe- sophageal reflux. Surgical history includes appendectomy as a teenager, a ventral hernia repair after her last child was born, and right knee arthroscopy about 5 years ago. Her medications include triamterene/hydrochlorthiazide 37.5/25 mg daily, acetaminophen 650 mg (2) twice daily , cal- cium citrate 600 mg/vitamin D 400 international units twice daily, omeprazole 20 mg daily p.r.n for heartburn, and hy- drocodone/acetaminophen 5/325 mg every 6h p.r.n. for severe pain. You perform a physical exam, discuss healthy diet and physical activity, order serum electrolytes and creatinine, refill her prescriptions, and advise her to schedule a follow-up ap- pointment in 3 months for preventative screening. You are about to conclude the visit and leave the room when Mrs. Abra- ham asks if she can get a vitamin B12 shot now. You question her about her need for B12 and Mrs. Abraham states she never knew how her previous primary care provider knew she had a vitamin B12 deficiency, but monthly shots have helped boost her energy over the past year. -
VI.2 Elements for a Public Summary VI.2.1 Overview of Disease Epidemiology Vitamin B12 Deficiency Can Have a Number of Possible
VI.2 Elements for a public summary VI.2.1 Overview of disease epidemiology Vitamin B12 deficiency can have a number of possible causes. Typically it occurs in people whose digestive systems do not adequately absorb the vitamin from the foods they eat. This can be caused by: Pernicious anemia, a condition in where there is a lack of a protein called intrinsic factor. The protein, which is made in the stomach, is necessary for vitamin B12 absorption. Other causes can be gastritis, surgery in which part of the stomach and/or small intestine is removed or conditions affecting the small intestine. Vitamin B12 deficiency can also occur in pregnancy and with long- term use of acid-reducing drugs. VI.2.2 Summary of treatment benefits A deficiency of vitamin B12 (cobalamin) is manifested by fatigue, weakness, mood fluctuations, memory loss, limb weakness, difficulty walking, tingling, and paralysis. Drug treatment involves the administration of vitamin B12 by injection. If the deficiency of vitamin B12 (cobalamin) depends on the underlying disease being resolved, the vitamin supplementation continues until normal levels of vitamin B12 are achieved. If the deficiency state cannot be resolved (e.g. inadequate secretion of intrinsic factor, genetic abnormalities related to the site absorption, etc.) therapy should be continued for life. VI.2.3 Unknowns relating to treatment benefits None.

A more sensitive method of screening for vitamin B12 defi- vided on page 993. ciency is measurement of serum methylmalonic acid and homocysteine levels, which are increased early in vitamin B12 deficiency. Use of the Schilling test for detection of pernicious anemia has been supplanted for the most part by serologic testing for pari- etal cell and intrinsic factor antibodies. Contrary to prevailing medical practice, studies show that supplementation with oral vitamin B12 is a safe and effective treatment for the B12 deficiency state. Even when intrinsic factor is not present to aid in the absorp- tion of vitamin B12 (pernicious anemia) or in other diseases that affect the usual absorption sites in the terminal ileum, oral therapy remains effective.
