Abstract

|
Serum creatinine-based eGFR and serum cystatin C-based eGFR are the most popular methods for measuring renal function. Thyroid hormone is known to affect serum creatinine-based eGFR and serum cystatin C-based eGFR; however, the clinical significance of thyroid dysfunctional patients of renal function evaluation has not been fully elucidated to date. This study examined the effect of thyroid hormone on serum creatinine-based eGFR and serum cystatin C-based eGFR. Moreover, we also evaluated the correlation analysis between serum creatinine-based eGFR and serum cystatin C-based eGFR in patients with thyroid dysfunction. A total of 442 patients with hypothyroidism and 284 patients with hyperthyroidism were investigated. A correlation analysis between thyroid hormone and serum creatinine- (and cystatin C-) based eGFR was performed. A correlation analysis between thyroid hormone and serum cystatin-C based eGFR indicated that serum cystatin-C based eGFR is more of an independent biomarker than serum creatinine-based eGFR in thyroid dysfunction patients. Therefore, serum cystatin C-based eGFR more accurately reflects renal function than serum creatinine-based eGFR in thyroid dysfunction patients.
