Objectives: Subclinical hypothyroidism (SCH) is also the major risk for cardiovascular disease like metabolic syndrome (MetS). Hence, the aim of this study is to assess the association of SCH in MetS patients.Materials and Methods: Ninety patients reporting to Saveetha Dental College and Hospitals were enrolled in the study which includes 40 patients with MetS and 40 healthy individuals. 5 ml of venous blood was collected and centrifuged. Then, it is analyzed for fasting blood sugar, serum triglycerides, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), and very low-density lipoprotein (VLDL) using the standard kit method. Then, Free T3, Free T4, and thyroid-stimulating hormone (TSH) were estimated by ELISA method. The data obtained were subjected to statistical analysis using the SPSS software.Results: SCH is 20% in cases when compared to 4.4% in controls, which was significant, p=0.024. The biochemical parameters were compared between the study population fasting blood glucose, triglycerides, total cholesterol, low-density lipoprotein cholesterol, and VLDL cholesterol was statistically significant, with p<0.001. TSH levels showed significant difference between two groups with the p=0.002.Conclusion: MetS patients should be screened for the SCH as an important risk factor in evaluation protocol. Mere correction of TSH levels can reverse the associated morbidity in these patients rather than leaving them untreated pushing them to a state of overt hypothyroidism with its attendant complications.

Abstract Background. Usually both hypothyroidism and hyperthyroidism are related to the cardiovascular and cerebrovascular disease development. The relationship between subclinical hypothyroidism has been widely investigated but the findings remain controversial. The aim of the present study was to evaluate the lipid profile in patients with subclinical hypothyroidism (SHypo) in comparison to controls and to determine the association of SHypo and dyslipidemia in attempt to find importance of small dense low-density lipoprotein cholesterol (sdLDL-C) in atherosclerosis. Material and methods. In this study we included 100 women, aged 30 to 70 years that were divided into subgroups according to their age. According to the values of levels of thyroid hormones they were divided into euthyroid (control) group (n = 64) and (newly discovered) subclinical hypothyroidism (SHypo) group (n = 36). A high-sensitivity C-reactive protein (hs-CRP) and lipid profile, including small dense low-density lipoprotein cholesterol (sdLDL-C) were determined. Body weight and height were measured and BMI calculated. History of the current illness, medication, alcohol consumption and cigarettes smoking were noted. Results. Changed lipid profile as well as elevated triglycerides and sdLDL-C were observed in the group with subclinical hypothyroidism compared to the control group. Conclusions. It is important to determine serum lipid levels, especially serum sdLDL-C levels at an early stage of subclinical hypothyroidism, since they represent atherogenic LDL particles and are better indicators for dyslipidaemia in subclinical hypothyroidism and the development of atherosclerosis with potential complications such as cardiovascular and cerebrovascular diseases.
