Documento congiunto di SIBIOC, della Società Italiana dell'Osteoporosi, del Metabolismo Minerale e delle Malattie dello Scheletro (SIOMMMS), della Sezione Italiana della European Ligand Assay Society (ELAS), e della Associazione Medici Endocrinologi (AME) relativo alla nota AIFA 96 sulla prescrivibilità dei farmaci per la carenza di Vitamina D, e raccomandazioni per la refertazione. [Joint Document from: Italian Society of Clinical Biochemistry and Clinical Molecular Biology (SIBioC), Italian Society of Osteoporosis, Mineral Metabolism, and Skeletal Diseases (SIOMMMS), Italina Section of Ligand Assay (ELAS), Association of Endocrinologists (AME) on "Nota 96" by the Italian Medicine Agency (AIFA) about prescription status of medications for Vitamin D deficiency, and recommendations for reporting]

Vitamin D, and its metabolites, have key roles in the functioning of virtually all tissues. Indeed, besides the unquestioned role in bone mineral metabolism, evidences have pointed out roles in inflammation and autoimmunity, skeletal muscle and cardiac function, neuromuscular communication. Therefore, vitamin D deficiency associates with rickets in the child, osteomalacia and increased risk of fracture in the adulthood and possibly with the increased risk of other pathological conditions. In order to regulate the prescription of vitamin D supplementation (cholecalciferol, cholecalciferol/calcium salts, calcifediol) to the adult population, and consequently to contain the costs sustained by the National Health System, the Italian Medicine Agency (AIFA) has recently drafted the "Nota 96" identifying the categories of patients, based on the laboratory measurement of serum levels of 25(OH)D, that can benefit from the reimbursement of vitamin D therapy. If the "Nota 96", AIFA has the merit to define rules in a field only sligtly regulated, several considerations emerged from its analysis. From an analytical point of view, the "Nota 96" does not consider the issues of reliability and reproducibility of 25(OH)D measurement and standardization of the units of measurement and reporting. On the clinical side, the "Nota 96" does not consider the epidemic vitamin D insufficiency/deficiency that needs an adequate preventive approach and, furthermore, beyond its roles, the agency indicates the clinical conditions for whom vitamin D prescription is allowed. This document analyses the content of "Nota 96" highlighting the points that need further evaluations and by giving possible different solutions; the document provides also recommendations on laboratory reporting of vitamin D measurements. © 2020 Biomedia.
