Euthyroid endocrine ophthalmopathy: a study of the pituitary-thyroid system
Acta Medica Academiae Scientiarum Hungaricae
|January 1, 1975
Summary
Thyroid stimulating hormone (TSH) response to thyrotropin-releasing hormone (TRH) is often abnormal in euthyroid endocrine ophthalmopathy. These abnormalities may predict future hyperthyroidism development.
Area of Science:
- Endocrinology
- Ophthalmology
- Thyroid Research
Background:
- Euthyroid endocrine ophthalmopathy presents with abnormal TSH response to TRH.
- A potential link exists between euthyroid and hyperthyroid forms of endocrine ophthalmopathy.
Purpose of the Study:
- To investigate the patterns of TSH response to TRH in euthyroid endocrine ophthalmopathy.
- To explore the relationship between euthyroid and hyperthyroid endocrine ophthalmopathy.
- To identify predictors of future hyperthyroidism in euthyroid endocrine ophthalmopathy patients.
Main Methods:
- Assessing TSH response to TRH in patients with euthyroid endocrine ophthalmopathy.
- Evaluating serum levels of triiodothyronine.
- Testing for Long-Acting Thyroid Stimulator (LATS) presence.
- Performing triiodothyronine suppression tests.
Main Results:
- Abnormal TSH response to TRH observed in euthyroid endocrine ophthalmopathy.
- Slightly elevated serum triiodothyronine levels detected.
- Presence of LATS in some patients.
- Abnormal triiodothyronine suppression tests noted.
Conclusions:
- The TSH-TRH axis is frequently disturbed in euthyroid endocrine ophthalmopathy.
- Findings suggest euthyroid and hyperthyroid ophthalmopathy may represent stages of the same disease process.
- Specific markers may indicate impending hyperthyroidism in euthyroid endocrine ophthalmopathy.
