Routine Administration of Vitamin K1 Prophylaxis to the Newborn
Routine Administration of Vitamin K1 Prophylaxis to the Newborn Practice Resource for Health Care Providers July 2016 Practice Resource Guide: ROUTINE ADMINISTRATION OF VITAMIN K1 PROPHYLAXIS TO THE NEWBORN The information attached is the summary of the position statement and the recommendations from the recent CPS evidence-based guideline for routine intramuscular administration of Vitamin K1 prophylaxis to the newborn*: www.cps.ca/documents/position/administration-vitamin-K-newborns Summary Vitamin K deficiency bleeding or VKDB (formerly known as hemorrhagic disease of the newborn or HDNB) is significant bleeding which results from the newborn’s inability to sufficiently activate vitamin K-dependent coagulation factors because of a relative endogenous and exogenous deficiency of vitamin K.1 There are three types of VKDB: 1. Early onset VKDB, which appears within the first 24 hours of life, is associated with maternal medications that interfere with vitamin K metabolism. These include some anticonvulsants, cephalosporins, tuberculostatics and anticoagulants. 2. Classic VKDB appears within the first week of life, but is rarely seen after the administration of vitamin K. 3. Late VKDB appears within three to eight weeks of age and is associated with inadequate intake of vitamin K (exclusive breastfeeding without vitamin K prophylaxis) or malabsorption. The incidence of late VKDB has increased in countries that implemented oral vitamin K rather than intramuscular administration. There are three methods of Vitamin K1 administration: intramuscular, oral and intravenous. The Canadian Paediatric Society (2016)2 and the American Academy of Pediatrics (2009)3 recommend the intramuscular route of vitamin K administration. The intramuscular route of Vitamin K1 has been the preferred method in North America due to its efficacy and high compliance rate. -

Received: 24 January 2019; Accepted: 16 February 2019; Published: 19 February 2019 Abstract: Vitamin K is an essential bioactive compound required for optimal body function. Vitamin K can be present in various isoforms, distinguishable by two main structures, namely, phylloquinone (K1) and menaquinones (K2). The difference in structure between K1 and K2 is seen in different absorption rates, tissue distribution, and bioavailability. Although differing in structure, both act as cofactor for the enzyme gamma-glutamylcarboxylase, encompassing both hepatic and extrahepatic activity. Only carboxylated proteins are active and promote a health profile like hemostasis. Furthermore, vitamin K2 in the form of MK-7 has been shown to be a bioactive compound in regulating osteoporosis, atherosclerosis, cancer and inflammatory diseases without risk of negative side effects or overdosing. -
An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Larry Stanford Merrifield for the M.S. in Food Science (Name) (Degree) (Major) Date thesis is presented June 26, 1964 Titie FACTORS AFFECTING THE ANTIMICROBIAL ACTIVITY OF VITAMIN K 5 Abstract approved (M^jor Tp&Sfesso/) Vitamin K, 4-amino-2-methyl- 1-naphthol hydrochloride, a 5 water soluble analog of vitamin K has been shown to possess an anti- microbial activity toward many bacteria, molds, and yeast. Much of the work reported in the literature is on its use as a food preserva- tive, and it was the purpose of this study to investigate some of the factors which might affect the antimicrobial activity of vitamin K in order to add insight into its more effective use as a food preserva- tive. Pure cultures of Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens were utilized. The effect of the method of application of vitamin K on Escherichia coli; the effect of purity of vitamin K against Escherichia coli; the bactericidal concentrations required for Escherichia coli, Bacillus subtilis, Proteus vulgaris, Staphlococcus aureus, and Pseudomonas fluorescens; the effect of an absence of oxygen; the effect of contact time with Escherichia coli; the effect of initial count/ml of Escherichia coli; and the synergistic action in combination with propylene glycol were studied. The results demonstrated that air oxidation of vitamin K was 5 necessary to obtain maximum inhibitory activity against Escherichia coli. The use of white, crystalline vitamin K synthesized in the laboratory, as compared to partially oxidized commercial prepara- tions, gave better results against Escherichia coli. -

Mephyton (Phytonadione Label
7918719 TABLETS MEPHYTON® (PHYTONADIONE) Vitamin K1 DESCRIPTION Phytonadione is a vitamin which is a clear, yellow to amber, viscous, and nearly odorless liquid. It is insoluble in water, soluble in chloroform and slightly soluble in ethanol. It has a molecular weight of 450.70. Phytonadione is 2-methyl-3-phytyl-1, 4-naphthoquinone. Its empirical formula is C31H46O2 and its structural formula is: MEPHYTON* (Phytonadione) tablets containing 5 mg of phytonadione are yellow, compressed tablets, scored on one side. Inactive ingredients are acacia, calcium phosphate, colloidal silicon dioxide, lactose, magnesium stearate, starch, and talc. CLINICAL PHARMACOLOGY MEPHYTON tablets possess the same type and degree of activity as does naturally-occurring vitamin K, which is necessary for the production via the liver of active prothrombin (factor II), proconvertin (factor VII), plasma thromboplastin component (factor IX), and Stuart factor (factor X). The prothrombin test is sensitive to the levels of three of these four factors II, VII, and X. Vitamin K is an essential cofactor for a microsomal enzyme that catalyzes the post-translational carboxylation of multiple, specific, peptide-bound glutamic acid residues in inactive hepatic precursors of factors II, VII, IX, and X. The resulting gamma-carboxyglutamic acid residues convert the precursors into active coagulation factors that are subsequently secreted by liver cells into the blood. Oral phytonadione is adequately absorbed from the gastrointestinal tract only if bile salts are present. After absorption, phytonadione is initially concentrated in the liver, but the concentration declines rapidly. Very little vitamin K accumulates in tissues. Little is known about the metabolic fate of vitamin K. -

Many countries have a Recommended Daily Intake (RDI) for vitamin K based on early research, and its necessary role in the activation of vitamin K-dependent coagulation proteins is known. In the past few decades, the role of vitamin K-dependent proteins in processes beyond coagulation has been discovered. Various isoforms of vitamin K have been identified, and vitamin K2 specifically has been highlighted for its long half-life and extrahepatic activity, whereas the dietary form vitamin K1 has a shorter half-life. In this review, we highlight the specific activity of vitamin K2 based upon proposed frameworks necessary for a bioactive substance to be recommended for an RDI. -
Adverse Effects of Antioxidative Vitamins

Biegański Memorial Regional Specialistic Hospital, Łódź, Poland Department of Endoscopy and One Day Gastroenterology Abstract High doses of synthetic antioxidative vitamins: A, E, C and β-carotene are often used on long-term basis in numerous preventive and therapeutic medical applications. Instead of expected health effects, the use of those vitamins may however lead to cases of hypervitaminosis and even to intoxication. The article points out main principles of safety which are to be observed during supplementation with antioxidative vitamins. Toxic effects resulting from erroneous administration of high doses of those substances on organs and systems of the organism are also discussed. Attention is drawn to interactions of antioxidative vitamins with concomitantly used drugs, as well as intensification of adverse effects caused by various exo- genous chemical factors. Moreover, the article presents the evaluation of supplementation with these vitamins, which was performed in large studies. Key words: Vitamins A, E and C, β-carotene, Supplementation, Side actions, Toxic effects INTRODUCTION pharmaceutical drugs, and their preparations are gener- ally sold over the counter.
