Association of Serum Ferritin, Folate, Vitamin B12 with Thyroid Hormone Levels in Patients with Thyroid Disorders.

ABSTRACT

INTRODUCTION: Anemia frequently occurs during course of clinical thyroid diseases. Without proper diagnosis & effective treatment of underlying thyroid disease, it is often difficult to achieve complete correction of anemia. AIM: The present study was conducted to assess prevalence & types of anaemia in patients with thyroid disorders. MATERIALS A cross sectional study was conducted on 160 patients including both hypothyroid & hyperthyroid patients at OPD/IPD in SRN Hospital affiliated to MLN Medical college Prayagraj between July 2021 & August 2022. Blood samples were taken to estimate CBC, GBP with Retic count, S. ferritin, S. folate, S. Vitamin B12, Thyroid profile. Data was entered in MS Excel Spreadsheet & appropriate statistical package applied. RESULT: Out of 144 hypothyroid patients, 102 (70.83%) were found to be anaemic & out of 16 hyperthyroid patients, 6 (37.5%) were found to be anaemic. In 102 anaemic hypothyroid patients, 56 (54.9%)had normocytic normochromic, 25 (24.5%) had microcytic and 21 (20.5%) had macrocytic anaemia. In 6 anaemic hyperthyroid patients, 3 (50%) had normocytic normochromic, 2(33.33%) had microcytic and 1 (16.67%) had macrocytic anaemia. CONCLUSION: High prevalence of anaemia was found in patients with thyroid disorders. Anaemia is an uncommon finding in hyperthyroidism but when present may be similar to that present in hypothyroidism. The most common type of anaemia in both hyperthyroidism & hypothyroidism was found to be normocytic normochromic, followed by microcytic & least common being macrocytic.
