These diseases need to be treated quickly and properly because if left untreated, they can impact brain development, thinking abilities, growth, puberty, and other important body functions. However, treating thyroid diseases in children can be challenging, as it's important to avoid both under- and overdosing.\n\nAlgorithms that help determine the best individual dose for children with thyroid diseases could reduce the risk of long-term problems, like impaired thinking and growth. This is especially important because cases of thyroid diseases in children are increasing worldwide.\n\nOptiThyDose is a new mathematical model developed to help doctors find the right dose for children with thyroid diseases.\n\nThe primary goal of this multicentric, randomised, two-arms and single-blinded study is to test how well OptiThyDose works for children with two types of thyroid diseases: Congenital Hypothyroidism (CH) and Graves' Disease (GD).\n\nIf proven effective, OptiThyDose could help ensure more accurate dosing of thyroid medications, leading to better hormone control, fewer side effects, and improved health outcomes in children with Congenital Hypothyroidism (CH) and Graves' Disease (GD).",[49,53,58,61],{"label":50,"type":51,"description":52,"interventionNames":41},"Control group w\u002F Congenital Hypothyroidism","NO_INTERVENTION","Patients with Congenital Hypothyroidism receiving routine levothyroxine (LT4) treatment",{"label":54,"type":55,"description":52,"interventionNames":56},"OptiThyDose w\u002F Congenital Hypothyroidism","EXPERIMENTAL",[57],"Other: OptiThyDose",{"label":59,"type":51,"description":60,"interventionNames":41},"Control group w\u002F Graves' Disease","Patients with Graves' Disease receiving routine carbimazole (CMZ) or methimazole (MMZ) treatment",{"label":62,"type":55,"description":60,"interventionNames":63},"OptiThyDose w\u002F Graves' Disease",[57],[65],{"type":6,"name":66,"description":67,"armGroupLabels":68,"otherNames":41},"OptiThyDose","OptiThyDose is an iterative mathematical model applied at each patient visit, consisting of three components: (i) a disease-specific pharmacometrics (PMX) model, (ii) an empirical Bayesian estimation (EBE) component, and (iii) an optimal control theory (OCT) component.
