Abstract

Objective: To compare plasma thiol-disulfide balance of primary Sjögren's syndrome, secondary Sjögren's syndrome, non-Sjögren's syndrome dry eyes and healthy subjects and to evaluate the correlation with clinical parameters. Material and Method: Sixty five female subjects were included in the study; 13 were primary Sjögren's syndrome, 18 were secondary Sjögren's syndrome, 19 were non-Sjögren's syndrome dry eye and 15 were healthy. Plasma native thiol, disulfide levels were measured and thiol-disulfide ratio was calculated. Patients were assessed for tear osmolarity, ocular surface staining scores according to Oxford staging, Schirmer I, tear break-up time and ocular surface disease index. Results: Demographic characteristics were similar among all groups. There was a statistically significant difference in plasma native thiol levels between the primary, secondary Sjögren's syndrome group, and the control group (p=0.001). Higher plasma disulfide levels in the nonSjögren's syndrome, primer Sjögren's syndrome, and secondary Sjögren's syndrome groups were statistically significant (p=0.002, p=0.001, p=0.001). In all groups, there was no significant correlation between plasma thiol-disulfide levels and tear osmolarity, ocular surface staining scores and ocular surface disease index (p>0.05). Conclusion: Thiols containing a sulphydryl group are non-enzymatic antioxidants and cause disulfide structure as oxides. Thiol-disulfide balance plays an important role in cellular events such as oxidative stress, apoptosis. In the pathogenesis, the thiol-disulfide balance may be important in dry eye syndromes in which oxidative stress-induced inflammation and apoptosis occur in ocular surface cells in advanced stages.

Özet

Amaç: Primer Sjögren sendromu, sekonder Sjögren sendromu, Sjögren sendromu olmayan (non-Sjögren sendromu) kuru göz hastalarıve sağlıklı bireylerin plazma tiol-disülfid den ge sini karşılaştırmak ve klinik parametrelerle korelasyonunu değerlendirmek. Gereç ve Yöntem: Onüç primer Sjögren sendromu, 18 sekonder Sjögren sendromu, 19 non-Sjögren sendromu kuru göz tanılı ve 15 sağlık lı olmak üzere 65 kadın çalışmaya dahil edildi. Plazma native tiol, disülfid seviyeleri ölçüldü, tiol-disülfid oranı hesaplandı. Gözyaşı ozmolaritesi, Oxford evrelemesine göre oküler yüzey boyanma dereceleri, Schirmer I, gözyaşı kırılma zamanı ve oküler yüzey hastalık indeksi sonuçları değerlendirildi.Bulgular: Tüm gruplar arasında demografik özellikler benzerdi. Primer Sjögren sendromu ve sekonder Sjögren sendromu ile kontrol grubu arasında plazma native tiol düzeylerindeki fark istatistiksel olarak anlamlıydı (p = 0,001). Primer Sjögren sendromu, sekonder Sjögrensend romu ve non-Sjögren sendromu kuru göz hastalarında plazma disülfid düzeyi (p=0,001, p=0,001, p=0,002). Tüm gruplarda, plazma tioldisülfid düzeyleri ile gözyaşı ozmolaritesi, oküler yüzey boyanma dereceleri ve oküler yüzey hastalık indeksi arasında anlamlı korelasyon saptanmadı (p>0,05).Sonuç: Sülfidril grubu içeren tioller enzimatik olmayan antioksidanlardır ve okside olarak disülfid yapısını meydana getirirler. Tiol-disülfid dengesi, oksidatif stres, apoptozis gibi hücresel olaylarda önemli rol almaktadır. Patogenezinde, oksidatif strese bağlı enflamasyonun ve ileri evrelerde oküler yüzey hücrelerinde apoptozisin yer aldığı kuru göz sendromlarında, tiol-disülfid dengesinin önemli olması muhtemeldir.
