About

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.

Full 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).

Enrollment: 44 estimated patients

Sex: All

Ages: 18 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion and exclusion criteria

Inclusion Criteria:Patients over 18 years old with CKD stages 3 and 4 were included in the study.

Exclusion Criteria: 1) acute systemic inflammatory disease; 2) pituitary disease in the past or present; 3) regular treatment with amiodarone, lithium, interferon, immunosuppressive drugs and glucocorticoids; 4) previously diagnosed hypothyroidism and undergoing levothyroxine replacement.

Trial design

44 participants in 1 patient group

Treatment:

Diagnostic Test: Thyroid function
