    Comparison of high-sensitivity C-reactive protein and fetuin-A levels before and after treatment for subjects with subclinical hyperthyroidism
    (Humana Press Inc., 2014) Bilgir O.; Bilgir F.; Topcuoglu T.; Calan M.; Calan O.
    This study was designed to show the effect of propylthiouracil treatment on sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels on subjects with subclinical hyperthyroidism. After checking sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels of 35 patients with subclinical hyperthyroidism, each was given 50 mg tablets of propylthiouracil three times daily. After 3 months, sCD40L, high-sensitivity C-reactive protein, and fetuin-A levels were then compared to the levels before treatment. Although high-sensitivity C-reactive protein and sCD40L levels were normal in the subclinical hyperthyroidism patients compared to the healthy controls, fetuin-A levels were statistically significantly higher (*p = 0.022). After treatment, fetuin-A levels of subclinical hyperthyroidism patients decreased statistically significantly compared to the levels before treatment (**p = 0.026). sCD40L and high-sensitivity C-reactive protein levels did not have a statistically significant difference compared to the control group and post-propylthiouracil treatment. In subclinical hyperthyroidism patients, high fetuin-A levels before propylthiouracil treatment and decreases in these levels after treatment in cases with subclinical hyperthyroidism indicated the possibility of preventing long-term cardiac complications with propylthiouracil treatment. © 2013 Springer Science+Business Media New York.

    Subclinical hypothyroidism: Comparison of adhesion molecule levels before and after levothyroxine therapy
    (SAGE Publications Ltd, 2014) Bilgir F.; Bilgir O.; Calan M.; Calan O.; Isikyakar T.
    Objective: Adhesion molecules are involved in inflammation, atherosclerosis and malignancy. This study measured levels of adhesion molecules before and after levothyroxine therapy in patients with subclinical hypothyroidism (SHO). Methods: Levels of soluble (s) intracellular adhesion molecule (ICAM)-1, s vascular cell adhesion molecule (sVCAM) VCAM-1 and sE-selectin were analysed in patients diagnosed with SHO, prior to administration of 50 mg/day levothyroxine orally for 3 months. Subsequently, levels of sICAM-1, sVCAM-1 and sE-selectin were reanalysed then compared with the pretreatment levels. Results: In 30 patients with SHO, levels of sICAM-1 were found to be significantly higher than those in healthy controls, (P=0.001). Post-treatment sICAM-1 levels were significantly lower than pretreatment levels (P=0.001). No significant differences were found in sVCAM-1 or sE-selectin levels between healthy controls and patients with SHO before treatment, or between patients with SHO pre- and post-treatment. Conclusions: Patients with SHO had significantly higher levels of sICAM-1 compared with controls. Levels became normal after treatment with levothyroxine. These findings emphasize the need for levothyroxine therapy in cases of SHO to normalize sICAM-1 levels. Such treatment helps to prevent the future development of atherosclerosis or cancer. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
