Abstract

Thyroid hormones have a very crucial role in the regulation of metabolism, proteins synthesis and influencing functions of various other hormones in the human body. While both kidneys play an essential role in the metabolism of thyroid hormone by conversion of thyroxine (T4) to triiodothyronine (T3). In patients with chronic kidney diseases, frequent abnormal thyroid functions are observed. Aim:To study the pattern of thyroid dysfunction in chronic kidney disease population and to evaluate the correlation existing in between severity of kidney failure and thyroid dysfunction Methods:This cross sectional observational study was conducted in the department of internal medicine in a tertiary care hospital, central India. 100 chronic kidney disease patients were included in the study. Diagnosis of chronic kidney failure was performed as per criteria laid down by Kidney Disease Outcome Quality Initiative. Blood was drawn for estimation of serum creatinine, GFR and thyroid profile. Results: Among 100 CKD patients, most of them (64%) were male with age ranging from 18 to 80 years with mean age of 57.08±10.35 years. Of the total patients, 6%, 12%, 29%, 26% & 27% patients belonged to CKD Stages 1,2,3,4 & 5 respectively. Low T3 is the most common thyroid dysfunction & the earliest abnormality noticed in CKD patients. The prevalence of low T3 syndrome in this study was 48%. Increasing trend for Low T3 prevalence with increasing severity of CKD was noticed in this study and was statistically significant (P
