Trial summary

A higher prevalence of thyroid disease has been associated with chronic kidney disease (CKD), and subclinical hypothyroidism seems to be the most common dysfunction. The aim is to evaluate thyroid function and autoimmunity in patients with CKD stages 3, 4 and 5. Read more about this study

About this study

A higher prevalence of thyroid disease has been associated with chronic kidney disease (CKD), and subclinical hypothyroidism seems to be the most common dysfunction. The aim is to evaluate thyroid function and autoimmunity in patients with CKD stages 3, 4 and 5. Cross-sectional study to be carried out on patients with stages 3 and 4 in a Nephrology outpatient clinic. Thyroid function is evaluated by measuring thyroid stimulating hormone (TSH), free thyroxine, free triiodothyronine and antithyroperoxidase antibodies (TPOAb) levels.

Read the detailed description

Cross-sectional study to be carried out on patients with stages 3, 4 and 5 in a Nephrology outpatient clinic. Thyroid function is evaluated by measuring thyroid stimulating hormone (TSH), free thyroxine, free triiodothyronine and antithyroperoxidase antibodies (TPOAb) levels. Free Thyroxine (FT4) will be measured by liquid chromatography tandem mass spectrometry and electrochemiluminescence immunoassay in order to compare methods in this population.

The glomerular filtration rate was estimated (eGFR) by the Chronic Kidney Disease Epidemiology Collaboration formula (CKD-EPI), and the CKD stages were defined according to the Kidney Disease Improving Global Outcomes directives (KDIGO).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Free thyroxine (FT4) levels in chronic kidney disease

    Free thyroxine levels through two different methods

    Measured: through study completion, an average of 3 years

  2. TSH levels in chronic kidney disease

    TSH levels

    Measured: through study completion, an average of 3 years

Secondary outcomes (2)
  1. Frequency of thyroid antibodies in chronic kidney disease

    antithyroperoxidase and antitireoglobulin antibodies

    Measured: through study completion, an average of 3 years

  2. Free triiodothyronine (FT3) levels in chronic kidney disease

    T3 levels

    Measured: through study completion, an average of 3 years

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Kidney Disease and Thyroid Dysfunction, run by Rio de Janeiro State University at 1 site in Brazil.

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

Who may be eligible to take part?

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: status not confirmed, as of the sponsor's last update on 9 Dec 2020. 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 Brazil. 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.

Are results available for this study?

Results are not available in the source record.

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?

Free thyroxine (FT4) levels in chronic kidney disease (time frame: through study completion, an average of 3 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04658524, which also lists 4 linked publications.

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 9 Dec 2020.
