Abstract
Subclinical hypothyroidism is characterised by elevated serum thyroid stimulating hormone (TSH) concentrations in association with normal free thyroid hormones. The aim of the study was to evaluate the prevalence and pattern of serum lipid alterations in patients with stable subclinical hypothyroidism in comparison to age- as well as sex-matched euthyroid group and also subgroup analysis between them in regard to age of presentation, sex, antithyroperoxidase (anti TPO) positivity, and TSH value. In this study, 100 patients of SCH were recruited, age ranged 17-68 years, majority (78%) being females, presenting mainly with non-specific symptoms and compared with 52 euthyroid control regarding lipid parameters. Of the subclinical hypothyroidism patients, only 10% had goitre and anti TPO was positive in 52% cases. Serum lipoprotein (a) above the age of 20 years, and total cholesterol, triglyceride and low density liporpotein cholesterol in the age group of 40-50 years were significantly elevated. In addition, total cholesterol, triglyceride and low density lipoprotein cholesterol levels in anti TPO positive cases and serum triglyceride and low density lipoprotein cholesterol in anti TPO negative patients showed statistically significant higher levels. In males only lipoprotein (a), but in females total cholesterol, triglyceride, low density lipoprotein cholesterol and liproprotein (a)--all were significantly elevated.
