Prospective Analysis of Lipid Variations in Hyperthyroid Subjects from Lahore, Pakistan.

Perturbations in the actions of T 3 and T 4 influence the normal metabolic pathways. Responsiveness of lipid biomarkers like LDL-C, HDL-C, TC, TG, Apo-A, and Apo-B after rehabilitation of thyroid profile attaining euthyroid state was determined. A total of 179 age-matched subjects of both genders were recruited for this research. Sixty healthy controls, thirty-four subclinical, fifty overt hyperthyroid, and thirty-five follow-up subjects having 3 months of Carbimazole therapy were enrolled. Biochemical analysis was performed by chemistry analyzer, RIA, and ELISA. One-way ANOVA was applied for the statistical analysis, while significance ( P < 0.05) of means was compared by the Student-Newman-Keuls (SNK) test. Pronounced reduction ( P < 0.001) of cholesterol in overt as compared to control and subclinical was noticed, whereas marked improvement ( P < 0.001) was evidenced in follow-up. Prominent elevation ( P < 0.05) of TG in follow-up was evidenced as compared to control. Overt presented marked reduction of HDL-C as compared to subclinical and control ( P < 0.01 and P < 0.001), respectively. Pronounced elevation ( P < 0.001) of HDL-C was evidenced after treatment. Overt presented reduction of LDL-C as compared to subclinical and control ( P < 0.01 and P < 0.05, respectively). The follow-up group demonstrated considerable ( P < 0.001) improvement of LDL-C after treatment and elevation ( P < 0.05) as compared to control. Overt presented reduction of Apo-B as compared to subclinical and control ( P < 0.05 and P < 0.001, respectively). Improvement ( P < 0.05) of Apo-B was evidenced in follow-up. Reduction ( P < 0.05) of Apo-A in overt as compared to control and elevation ( P < 0.05) in follow-up as compared to overt was evidenced. Conclusively, improvement after treatment was evidenced in lipid profile.
