Reliable Earlier and Causative Biomarker in newly Diagnosed Hypothyroid Cases—Vitamin D: A Case–control Study

Abstract

ABSTRACT Background In Indian population there are 42 million people suffering from hypothyroidism. Hence, even though thyroid-stimulating hormone (TSH) has been used as the diagnostic marker of hypothyroidism, there arises a need to evaluate an earlier and a causative marker for hypothyroidism and thus it could be a better predictor of the disease in the earlier stages only. Aims and objectives The aim of the study is to identify a reliable earlier and one of the causative biomarkers of hypothyroidism. Materials and methods This study was conducted in 200 cases of newly diagnosed hypothyroidism and 200 controls of healthy individuals. Vitamin D, intact parathyroid hormone, TSH, triiodothyronine, thyroxine, and calcium were measured. Results It was observed that vitamin D was significantly decreased in hypothyroid cases. There was a negative correlation between vitamin D and TSH. Conclusion Vitamin D being one of the causative factors in thyroid disorders should be included as a routine parameter of analysis in hypothyroid cases and supplementation of vitamin D also to be initiated by the clinicians to avoid the progression to overt hypothyroidism in the newly diagnosed cases.
