CORRELATION OF THYROID HORMONES IN PATIENTS WITH CHRONIC KIDNEY DISEASE: AN OBSERVATIONAL STUDY

Abstract

Introduction: Chronic kidney disease (CKD) is an international public health problem affecting about 5–10% of the population. It is the ninth leading cause of death. A trend towards increased incidence and prevalence is being reported worldwide with epidemic proportions in many countries. CKD is associated with variety of endocrine disturbances among which thyroid dysfunction is most common. This is probably due to reduce circulating hormone levels, altered binding of hormone to carrier protein or due to reduced peripheral metabolism of hormone.

Materials and Methods: The study included 100 patients diagnosed with CKD. Both male and female patients aged between 30-70 years were selected for the study. Estimated Glomerular Filtration Rate (eGFR) was calculated using Modification of Diet in Renal Disease (MDRD) formula. Total T3, Total T4, TSH levels were measured by CLIA methodology.

Results: Statistically significant alteration in TSH (p<0.01) values were seen with eGFR suggesting that alteration in the eGFR may lead to thyroid hormone resistance.
