Full description
Various diagnostic strategies exist for the identification of a cobalamin deficiency. In a retrospective study with existing serum values of vitamin B12 and holotranscobalamin 4 strategies are simulated and the results and costs are compared.
A cobalamin deficiency can have various causes: Dietary habits (vegetarian, vegan), advanced age, pernicious anaemia, gastrectomy, drug interactions (metformin, proton pump blocker). Therapy is often performed by intramuscular administration of cobalamin. However, oral preparations are also available in very different dosages. Investigators want to investigate with focus groups whether different patient groups are aware of a (potential) deficiency, how cobalamin is actually substituted (with registered or otherwise acquired products) and which therapy would lead to best adherence.
