Initial disease severity and methimazole titration for Graves' disease: a retrospective longitudinal cohort study
Authors' conclusion
When given a larger dose of methimazole, patients with severe thyrotoxicosis from GD reach euthyroid status as quickly as other patients with GD. However, these patients have more lability in thyroid control and may benefit from more frequent monitoring. After 6 months, severity of initial thyrotoxicosis was not associated with methimazole dose.
Study context
- Population
- Patients aged ≥18 years diagnosed with graves' disease (GD) treated with MMI, single tertiary medical center, 2018–2024
- Participants
- 152 patients1,432 encounters
- Exposure
- Association of initial disease severity (IDS), age and sex with MMI titration and thyrotoxicosis control
- Outcome
- Association of IDS, age and sex with average decrease in MMI dose per encounter, biochemical thyroid status per encounter, time until first euthyroid encounter, and MMI dose after 180 days

Main finding
As reported in the abstract
- IDS positively associated with percentage dose reduction of MMI per encounter
- P = .012
- IDS positively associated with proportion of hypothyroid encounters
- P = .0101
- No association of IDS with proportion of hyperthyroid encounters
- P = .088
- No association of IDS with MMI dose after 180 days
- P = .222
Observational data: associations, not effects.
