Oestrogen therapy in Turner's syndrome

Area of Science:

• Pediatric Endocrinology
• Genetics and Genetic Diseases

Background:

• Turner's syndrome is associated with growth and developmental deficiencies.
• Oestradiol is a key hormone for growth and development.

Purpose of the Study:

• To evaluate the effect of low-dose 17-beta-oestradiol on growth rate in Turner's syndrome.
• To investigate potential mechanisms of oestradiol's effect on growth.

Main Methods:

• Observational study of 35 girls with Turner's syndrome treated with 17-beta-oestradiol.
• Analysis of growth rate, bone maturation, and final height.

Main Results:

• A definite increase in growth rate was observed in the first year of therapy.
• Bone maturation was accelerated.
• No reduction in final height was found.

Conclusions:

• Low-dose oestradiol therapy is effective in increasing growth rate in Turner's syndrome.
• Potential mechanisms include effects on somatomedin generation, GH secretion, and bone tissue.
• Accelerated bone maturation does not negatively impact final height.
