Thyroid hormones (TH) regulate the metabolic processes required for normal development and growth; also, to organizemetabolism in adults, any defect in thyroid function leads to abnormality in thyroid hormones level. The current study hasbeen designed to find the relationship between retinol-binding protein-4 and progranulin in the serum of Iraqi women withhypothyroidism and hyperthyroidism, also, to study whether these patients are exposed to a risk of developing diabetes mellitus,and PGRN may be a biomarker in detection early stage of diabetes mellitus.Materials and Methods: in this study, serum samples were obtained from 50 Iraqis women patients, [25 patients withhypothyroidism (G2) and 25 patients with hyperthyroidism (G3)] in addition to 25 healthy women as a control group (G1),their ages ranged from (30–55) years. The patients attended the Specialized Center for Endocrinology and Diabetes, Baghdad.Results: the results in this study showed a highly significant decrease in RBP4 levels and a significant increase in PGRNlevels in G2 and G3, respectively, compared with G1. Additionally, a considerable increase in BMI, FSG, and HbA1C levelsin G2 and G3 Comparison with G1, and a significant difference between G2 and G3 patients.Conclusions: The current study is the first to shed light on the relationship between PGRN and thyroid disorder, which providesa guide on the increase in PGRN levels of patients with a thyroid disorder, especially in patients with hyperthyroidism, relatedwith metabolic and glucose abnormalities, and then, it may be a trustable predictive biomarker for detection early stage ofdiabetes mellitus type 2 in patients with a thyroid disorder. Also, there was a significant correlation between RBP4 and PGRN inthese patients. In addition, these patients with hyperthyroidism were more likely to diabetes than patients with hypothyroidism (7) (PDF) A Comparative Study of Retinol-binding protein-4 and Progranulin in Iraqi Women with Thyroid Disorder.
