摘要: Background: The aim was to evaluate the association of plasma 25-hydroxyvitamin D (25-O H D) and vitamin binding protein (VDBP or Gc-globin) gene polymorphism with oxidant-antioxidant profiles in patients chronic obstructive pulmonary disease (CO PD), their role as biomarker risk factors susceptibility severity COPD. Methods: Eighty diagnosed CO PD (mild, moderate severe according lung function tests; FEV 1%) 80 healthy controls were included study. Serum nitric oxide (NO) lipid peroxide (LP), reduced glutathione (R G SH), superoxide dismutase (SO D), peroxidase (GSH-Px), catalase (CAT) activity, 25-O VDBP analyzed all subjects. Results: COPD had significantly decreased serum NO, SOD, RGSH, GSH-Px, CAT 25-OHD versus controls, but increased LP patients, levels lower (4 1.4 9± 13 .65 ng/mL) more (3 0 .5 4 ± 9 .0 ng/mL; sensitivity 79.2% ; specificity 73.2% , p< 0.001) mild Co Pd . genotypes frequencies c1S-1S= 23.8% Gc1F-Uvod: Cilj je bio da se utvrdi povezanost između 25-hidroksi-vitamina u plazmi i polimorfizma gena za D-vezujuci (vitamin D-binding protein, ili oksidantnih-antioksidantnih profila kod pacije-nata sa hronicnom opstruktivnom bolescu pluca (H O BP), kao njihova uloga faktora rizika biomarkera podlož-nost ozbiljnost HOBP Metode: U ovu studiju ukljuceno pacijenata dijagno-zom (blag, umeren težak oblik na osnovu testova plucne funkcije; zdravih kontrolnih ispitanika. Kod svih ispitanika analizirani su nivoi azot-oksida lipid-peroksida (LP) serumu, redukovani glutation (RGSH), superoksid-dismutaza (SOD), peroksidaza (GSH/Px) plazmi, aktivnosti katalaze (CAT), polimorfizam VDBP. Rezultati: Oboleli od imali znacajno snižene nivoe NO poređenju s kontrolom, ali povisen se-rumski obolelih bili niži 1 ,4 3 ,6 5 odnosu kontrolu, jos teskim oblikom ,5 ,0 osetljivost 79,2% specificnost 73,2% p < 0,0 01) blagim umerenim oblicima 332 Al-Azzawi et al.: Vitamin 1S= 28.8% c F -1 = /, Gc1S-2 20°/o, -2 .3 / Gc2-2 Also, variants S 8 .1 Gc2 6 .6 However, Gc1F-1S Gc1 higher than (1 2 0.0 09, p= 0.001, respectively).
