Bone Health in Adolescents and Young Adults With Oral Macro-progestin Treatment

NCT04007614 · Status: WITHDRAWN · Type: OBSERVATIONAL

No results posted yet for this study

Summary

Many factors are known to influence the acquisition of bone capital, especially estrogens in women. Estrogens have a major role in bone growth and the acquisition of bone mass peaks during puberty. This peak of bone mass is an important determinant of the risk of osteoporotic fracture in adulthood.

It is known that estrogen deficiency increases the rate of bone remodeling and engenders an imbalance between resorption and bone formation, which can lead to osteoporosis.

Oral estroprogestin contraceptives have an anti-gonadotropic effect and suppress estrogen secretion by the ovaries.

However, studies in adolescents and young adults are rare and evidence of an effect on bone is still inconclusive, although there is increasing evidence that oral estroprogestin contraceptives in teenage girls may compromise the performance of the bone mass.

Macro progestins treatments are prescribed in France to patients with contraindications to estroprogestin treatments. This practice is french and few recommendations exist on the use of these molecules by the oral route. There are no studies that describe the impact of these oral treatments on the bone health of young women treated.

The Department of endocrinology, gynecology and pediatric diabetes of Necker-Enfants Malades hospital, follows many young girls taking a macro progestin treatment. This study is exclusively descriptive and will focus on the clinical and medical datas available on the bone health of these patients.
