Objective. The aim of this study was to assess whether subclinical hypothyroidism (SCH) is associated with dyslipidaemia and arterial hypertension. Methods. At the Department of Endocrinology, Diabetes and Metabolic Disorders, Skopje, R. Macedonia, we examined 24 consecutive patients with SCH and 13 healthy controls in a period of 6 months. SCH was defined as an elevated thyrotropin (TSH) (> 4.2 mU/1) and normal free thyroxine (IT4) level (10.3-24.45 pmol/l). None of the patients had been previously treated with thyroxine. In all participants we determined blood pressure, body mass index (BMI), TSH, IT4, antibodies to thyroid peroxidise (TPOabs), total lipids (TL), total cholesterol (TH), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), and triglycerides. Results. Mean diastolic blood pressure increased in SCH patients vis-a-vis controls (85 vs. 74 mmHg; p < 0.05). Mean values of TL, TH, HDL-C, LDL-C, triglycerides, TC/HDL-C, and LDL-C/HDL-C were no different in patients with SCH compared with controls. Individual analysis revealed that the percentages of patients with SCH having arterial hypertension (29%), hypertriglyceridaemia (34.78%), elevated LDL-C (41.66%), elevated TC/HDL-C (21.7%), and LDL-C/HDL-C (21.74%) ratios were higher than the percentages in controls. No significant correlation between TSH and biochemical parameters was detected. Conclusion. Our study revealed that SCH patients have a greater prevalence of dyslipidaemia and arterial hypertension, and, as well, a greater value of mean diastolic pressure vs. control patients.

    Abstract. The Greek screening program for primary congenital hypothyroidism was initiated in 1979. By early 2000, thyrotropin measurements had been performed in 1,976,719 newborns, using dried blood spots obtained by heel prick. Among these children, 584 were diagnosed with congenital...

    Hypothyroidism is an endocrine disorder characterized by abnormally low thyroid hormone production, resulting in the deficiency of thyroid hormone. Hypothyroid can be treated by giving synthetic drug intake of L-thyroxin (T4) and L-triiodothyronine (T3) as a replacement or supplementary therapy...
