Abstract

We aimed to evaluate the genetic variation of poly (ADP-ribose) polymerase-1 (PARP-1) as risk factor in development of Graves' disease (GD) and Graves' ophthalmopathy (GO) among Chinese individuals. Patients with confirmed diagnosis of GD or healthy individuals with no clinical symptoms of hyperthyroiditis were enrolled at the Department of Ophthalmology, Tianjin First Center Hospital, China. Genetic polymorphism was studied in plasma DNA samples of subjects by polymerase chain reaction of restriction fragment length polymorphism to confirm our hypothesis. Cytokine levels were measured routinely on serum samples of subjects by sandwich ELISA technique. Patients with GG genotype (odds ratio (OR) 95% CI = 2.25 (1.35-3.73), p = 0.002) and carriers of G allele (OR = 2.03 (1.23-3.36), p = 0.006) were at high risk of developing ophthalmopathy. Polymorphism of del/ins of nuclear factor-K[kappa]1 gene (NF[kappa]B1) gene (OR = 7.1 (2.88-17.52), p < 0.0001) and PARP-1 C410T polymorphism was found to be associated with GO (p < 0.05). Cytokine level was significantly higher in patients with GD (p < 0.05), but no significant change in cytokines level among GO patients from baseline (p > 0.05). Our study results recommended that polymorphism of PARP-1 gene is more likely responsible for development of GD in Chinese individuals. We also observed that the polymorphism of gene-related del/ins to NF[kappa]B1 in development of GO. Key words: poly (ADP-ribose) polymerase-1, Graves' disease, Graves' ophthalmopathy, cytokine, polymorphism, gene, genetic polymorphism. Resume: Nous visions a evaluer la variation genetique de la poly (ADP-ribose) polymerase-1 (PARP-1) comme facteur de risque de la maladie de Graves (MG) et de l'ophtalmopathie de Graves (OG) chez des Chinois. Nous avons inscrit a l'etude des patients porteurs d'un diagnostic de MG confirme ou des personnes en bonne sante sans symptomes d'hyperthyroidie dans le service d'ophtalmologie du Premier Hopital central de Tianjin, en Chine. Pour confirmer notre hypothese, nous avons etudie le polymorphisme genetique dans des echantillons plasmatiques d'ADN des sujets a l'aide de l'amplification en chaine par polymerase du polymorphisme des sites de restriction. Nous avons mesure de routine les taux de cytokines dans des echantillons de serum des sujets a l'aide de la technique immunoenzymatique en sandwich. Les patients presentant un genotype GG (rapport de cotes (RC) = 2,25 avec IC a 95 % de 1,35 a 3,73, p = 0,002) et les porteurs de l'allele G (RC = 2,03 (1,23 a 3,36), p = 0,006) etaient exposes a un risque eleve de presenter une ophtalmopathie. Nous avons observe que le polymorphisme de type del/ins du gene du facteur nucleaire [kappa]B1 (NF[kappa]B1) (RC = 7,1 (2,88 a 17,52), p < 0,0001) et le polymorphisme C410T du gene de la PARP-1 etaient associes a l'OG (p < 0,05). Les taux de cytokines etaient nettement plus eleves chez les patients atteints de MG (p < 0,05), mais nous n'avons observe aucune variation notable des taux de cytokines chez les patients atteints d'OG depuis le debut de l'etude (p > 0,05). Les resultats de notre etude montrent que le polymorphisme du gene de la PARP-1 est plus susceptible d'etre responsable de l'apparition de la MG chez les Chinois. Nous avons aussi observe que le polymorphisme (del/ins) du gene NF[kappa]B1 est associe a la presentation de l'OG.
