The determinants of leptin, angiopoietin like 8, and thyroid hormones levels in Saudi females with type 2 diabetes mellitus: A retrospective study.

ABSTRACT

This study aimed to assess the prevalence of thyroid dysfunction, as measured by hormone levels, in Saudi women with type 2 diabetes mellitus (T2DM). The study will also assess thyroid hormones and leptin, angiopoietin like 8 (ANGPTL8), obesity, and cardiovascular diseases (CVD) in T2D patients. A total of 250 women aged 40 to 60 years with T2DM were retrospectively studied between 2021 and 2022. This research examined medical records for T2DM patients. In this investigation, no T2DM patients had thyroid autoantibodies in their medical records. These patients were chosen for their FT4 and TSH values. All participants were Saudi females with T2DM, aged 54.5 years. Of the 250 participants, 32% had hypothyroidism, 14.8% had hyperthyroidism, and 40.8% (102) had no thyroid disease. Hypothyroidism (7.8 ±â€…0.67 mmol/L) exhibited greater fasting blood glucose (FBG) levels than hyperthyroidism (7.1 ±â€…0.64 mmol/L) (P < .05). Hypothyroid and hyperthyroid females had significant differences in high density lipoprotein-cholestrol (HDL-C), triglycerides, triglyceride glucose (TyG) index, body mass index (BMI), waist circumstance (WC), high-sensitivity C-reactive protein (hs-CRP), leptin, ANGPTL8, insulin resistance (IR), and insulin levels (P < .05). Pearson's correlation test showed that T2DM patients' HDL-C levels were favorably but negatively correlated with leptin and ANGPTL8 levels. In hypothyroidism, thyroid stimulation hormone (TSH) is favorably linked with glycated hemoglobin (HbA1c), triglyscride (TG), TyG index, BMI, WC, leptin, ANGPTL8, hs-CRP, and IR. T2DM is linked to thyroid malfunction, notably hypothyroidism, which correlates positively with TSH. TSH variations due to increasing leptin, ANGPTL8, and TyG index may enhance the risk of insulin resistance diseases, such as obesity and CVD, in Saudi females with T2DM.
