Objectives: Some evidence suggests gene-treatment interactions might cause persistent symptoms in individuals receiving levothyroxine (LT4) treatment. We investigated, as previously hypothesized, if single nucleotide polymorphisms (SNPs) in rs225014 (Thr92Ala), rs225015, or rs12885300 (ORFa-Gly3Asp) in the Deiodinase 2 gene (DIO2), or rs17606253 in the Monocarboxylate Transporter 10 gene (MCT10) were associated with outcomes indicative of local tissue hypothyroidism in LT4-tre...

Background: Increased oxidative stress has been linked to both hypo- and hyperthyroidism. Whole-body oxidative stress can be estimated by the oxidized guanine nucleosides, 8-oxo-7,8-dihydroguanosine (8-oxoGuo) and 8-oxo-7,8-dihydro-2’-deoxyguanosine (8-oxodG), derived from RNA and DNA, respectively. These biomarkers have been associated with increased morbidity and mortality in several diseases but are not well explored in humans with thyroid disorders.<p class="abste...

Treatment of hyperthyroidism reduces the systemic oxidative stress load, as measured by biomarkers of RNA and DNA damages

Larsen Camilla , Ryom Riis Kamilla , Hillert Winter Kristian , List Larsen Emil , Ellervik Christina , Hegedüs Laszlo , Brix Thomas , Enghusen Poulsen Henrik , Joop Bonnema Steen

Background: Increased oxidative stress has been linked to both hypo- and hyperthyroidism. Whole-body oxidative stress can be estimated by the oxidized guanine nucleosides, 8-oxo-7.8-dihydroguanosine (8-oxoGuo) and 8-oxo-7.8-dihydro-2’-deoxyguanosine (8-oxodG), derived from RNA and DNA, respectively. These biomarkers have been associated with increased morbidity and mortality in several diseases but are not well explored in humans with thyroid disorders.<p class="abst...

Treatment of hypothyroidism does not affect whole-body oxidative stress, as measured by biomarkers of RNA and DNA damage

Ryom Riis Kamilla , Larsen Camilla , Winther Kristian H. , Larsen Emil L. , Ellervik Christina , Hegedüs Laszlo , Brix Thomas , Poulsen Henrik E. , Bonnema Steen J.

Background: Hyperthyroidism as well as hypothyroidism have been associated with oxidative stress, caused by an imbalance between pro-oxidants and antioxidants. Oxidative stress may damage the genomic apparatus and other cellular structures. Urinary excretion of 8-oxo-7.8-dihydroguanosine (8-oxoGuo) and 8-oxo-7.8-dihydro-2’-deoxyguanosine (8-oxodG), respectively, represent global RNA and DNA oxidation, thus reflecting oxidatively generated modification of nucleic acids in...

Whole-body oxidative stress measured by biomarkers of RNA and DNA damage is higher in hypothyroid women, even after treatment, than in healthy individuals, measured by biomarkers of RNA and DNA damage

Introduction: Hypothyroidism has been associated with oxidative stress. Urinary excretion of 8-oxo-7,8-dihydroguanosine (8-oxoGuo) and 8-oxo-7,8-dihydro-2’-deoxyguanosine (8-oxodG), respectively, represent whole-body RNA and DNA oxidation. While these biomarkers have been associated with increased morbidity and mortality in various diseases, they have been only sparsely explored in patients with thyroid disorders.Method: In 45 women with newly diagn...
