We read with interest the article by Nicole S. Glaser et al. We have
following comments to offer:
Baseline TSH receptor stimulating antibody (TSHRAb) titres and the
fall in titres with anti-thyroid drug therapy has been shown to predict
remission in Graves' disease.(1) Follow up titres of TSHRAb in these
cohorts could have helped in prediction of remission.
The dose of Propylthiouacil (PTU) used varied from 5-7 mg/kg body
weight. As the BMI in the two group was different (higher in the remission
group), this could have meant use of higher dose of PTU in the group
having remission, thus contributing to remission.
Role of ultrasound for echogenecity and color doppler flow study for
vascularity of thyroid gland can help assessing disease activity and may
predict remission. (2)
