[Effect of thyroid function on ketogenesis (author's transl)]

|November 1, 1980
Summary
Thyroid hormone excess, particularly triiodothyronine (T3), increases ketone body levels during starvation in rats. This hormonal effect is also observed in humans with Grave's disease, correlating with elevated thyroid hormone levels.
Area of Science:
- Endocrinology
- Metabolic Research
Context:
- Thyroid hormones play a crucial role in regulating metabolism.
- Starvation significantly alters metabolic pathways, including glucose and ketone body production.
- Previous studies have indicated a link between thyroid status and metabolic changes.
Purpose:
- To investigate the direct effects of thyroid hormone excess on ketone body and glucose metabolism during starvation.
- To compare these effects in a rat model and in human patients with Grave's disease.
Summary:
- In rats, thyroid hormone excess elevates ketone body and glucose levels during the initial phase of starvation.
- Isolated liver cells from thyroid hormone-deficient rats show reduced ketone body production, which is restored by triiodothyronine (T3) administration.
- Patients with Grave's disease exhibit increased ketone body levels, significantly correlated with their thyroid hormone levels.
Impact:
- Demonstrates a direct role of T3 in regulating ketone body production.
- Provides mechanistic insights into metabolic alterations in hyperthyroid states.
- Highlights the clinical relevance of thyroid hormone levels in metabolic disturbances.
