About this study

Official title: Effects of Levothyroxine Treatment on Hemodynamic and Isotopic Renal Functions in Subclinical Hypothyroidism

Renal and cardiovascular effects of subclinical hypothyroidism, defined by a high TSH and normal T4 are less known and the indications for treatment of subclinical hypothyroidism are subject to controversies.

The investigators propose to assess whether the hormone replacement for subclinical hypothyroidism in patients with chronic kidney disease is beneficial for hemodynamic and renal functions and which mechanisms are involved.

Isotopic measurements of glomerular filtration and renal blood flow and an hemodynamic evaluation by transthoracic echocardiography and flow-mediated vasodilation will be carried out before and 6 months after substitution.

Read the detailed description

Animal experimental hypothyroidism is associated with renal and hemodynamic abnormalities. In human, exact measurements of GFR showed a decline in GFR after thyroidectomy and an increase in GFR and renal blood flow after hormone replacement. Renal and cardiovascular effects of subclinical hypothyroidism, defined by a high TSH and normal T4 are less known and the indications for treatment of subclinical hypothyroidism are subject to controversies. A retrospective study suggests that treatment of subclinical hypothyroidism may slow the degradation rate of renal function estimated by MDRD. However, the potential hemodynamic benefit of treatment has not yet been studied.

The investigators propose to assess whether the hormone replacement for subclinical hypothyroidism in patients with chronic kidney disease is beneficial for hemodynamic and renal functions and which mechanisms are involved.

Isotopic measurements of glomerular filtration and renal blood flow and an hemodynamic evaluation by transthoracic echocardiography and flow-mediated vasodilation will be carried out before and 6 months after substitution. This open prospective study will include 16 patients in order to detect an increase of 1.2 standard deviation for the measured glomerular filtration.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing LEVOTHYROXINE in people with Subclinical hypothyroïdism, run by Centre Hospitalier Universitaire de Nice at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: withdrawn, as of the sponsor's last update on 28 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

KIDNEY CLEARANCE (time frame: Before treatment and 6 months after treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 28 Oct 2016.
