Introduction: Elevated anti-thyroid peroxidase (Anti-TPO) antibodies and thyroid
stimulating hormone (TSH) levels in hypothyroidism have been linked to the alter the
vitamin B12 metabolic pathway thereby imparting the anemia. Thyroid peroxidase is
an important enzyme responsible during organification of iodide for synthesis of
thyroid hormone. Antibodies to TPO are formed as a part of autoimmune response of
body causing autoimmune thyroiditis in patients. Antibodies to thyroid peroxidase
(TPO) are clinically useful markers of thyroid autoimmunity
Objectives: Present study aims to correlate the thyroid stimulating hormone and antithyroid
peroxidase expression in Anti-TPO positive patients with the anemia.
Methods:60 patients who were anti-TPO positive and hypothyroid were recruited in
present study.TSH level, anti-TPO antibodies level and haemogram was analysed
among all patients.
Results: There was a positive correlation between the haemoglobin and TSH level (r=
0.09580). There was a negative correlation between the Haemoglobin and Anti-TPO
expression (r= -0.2086).
Conclusion: Present study revealed a correlation of anemia with TSH level and Anti-
TPO expression which have the diagnostic value. Anti-TPO positive hypothyroid
patients have risk of developing anaemia.
