Hypothyroidism Clinical Trial
Official title:
Survey for the Initial Treatment of Hypothyroidism in France
This observational survey with prospective and/or retrospective follow-up is designed to study practices for the initial treatment of hypothyroidism in France without modifying subject treatment.
Thyroid disorder can be central, caused by a deficiency in thyroid stimulating hormone (TSH)
production; or peripheral, caused by the decrease in the plasma concentration of thyroid
hormones, more specifically of free thyroxine (free T4). Peripheral hypothyroidism is caused
by the decrease in the production capacities of the thyroid gland.
The treatment of hypothyroidism is based on the restoration and maintenance of biological
(judged on the basis of the standardised TSH and T4 values) and clinical euthyroidism.
A number of forms of thyroid hormones are available in the French market (Euthyral®,
Cynomel®, L-thyroxine drops®), of which, Levothyrox® is the most frequently prescribed drug
in this category.
The treatment of peripheral hypothyroidism, in particular, is well codified and almost
consensual. In France, there is no published observational study, based on which one can
document the manner in which subjects are treated. This observational study is set up to
document these practices.
OBJECTIVES The principal objectives of this survey is to to get information on the use of
Levothyrox in France
- Circumstances of diagnosis
- Record realised
- Terms and conditions of treatment by the general practitioner and/or the
endocrinologist
The secondary objective is to evaluate the inclusion criteria for levothyroxine treatment.
For each subject the participating doctor will complete a follow up questionnaire form until
the first control level of TSH after the diagnosis of hypothyroidism.
