Correlation between severity of thyroid dysfunction and renal function.

Objective: Renal function is profoundly influenced by thyroid status; however, this has not been studied in detail in human subjects. The purpose of the present study was to determine the relationship between renal function and thyroid status before and after treatment for hypothyroidism and hyperthyroidism, respectively.

Design And Patients: In 37 consecutive hypothyroid and 14 hyperthyroid patients renal function as measured by plasma creatinine and glomerular filtration rate (GFR) [based on the modification of diet in renal disease (MDRD) formula] was determined before treatment and after regaining euthyroidism.
