Early Biochemical Response to Antithyroid Drugs in Graves’ Disease: The Role of Initial Dosing

Abstract:

Introduction: Optimal initial antithyroid drugs (ATD) dosing may achieve rapid improvement in thyroid hormone levels while minimizing risk of adverse events. As ATD have become the most common first line therapy for the treatment of Graves’ disease (GD), we examined trends over time in initial ATD dosing, and the association between guideline-based ATD dosing with time to normalization of FT4 and frequency of adverse events. Methods: This is a single cohort retrospective study in Mayo Clinic, Rochester, MN. We identified adults (≥18 years old) diagnosed with new onset GD between January 1, 2002-December 31, 2019 treated with at least 14 days of ATD and with available initial follow up data within 3 months prior to a dose change. Propylthiouracil (PTU) doses were converted to Methimazole (MMI) equivalents at 10:1 ratio. Guideline concordant care was defined as initial ATD dosed based on …
