ABSTRACT

Type 2 Diabetes Mellitus (T2DM) and hypothyroidism frequently coexist and contribute to a pro-inflammatory state, potentially complicating disease progression and management. This cross-sectional study aimed to evaluate the correlation between Neutrophil-to-Lymphocyte Ratio (NLR), Platelet-to-Lymphocyte Ratio (PLR), and Thyroid-Stimulating Hormone (TSH) levels in individuals with T2DM and hypothyroidism. A total of 200 participants were enrolled, including 100 cases and 100 age- and sex-matched controls. NLR and PLR were significantly elevated in the case group, with a strong positive correlation observed between TSH and NLR (r = 0.558, p < 0.001), and a moderate correlation with PLR (r = 0.397, p < 0.001). ROC analysis showed good diagnostic performance for NLR (AUC = 0.795), while PLR showed limited discriminatory ability (AUC = 0.601). These findings suggest that NLR may serve as a reliable, low-cost inflammatory marker in T2DM patients with hypothyroidism.
