Abstract

Objective: The presence of antinuclear antibodies (ANA), directed against intracellular antigens, is a distinctive feature of systemic autoimmune rheumatic diseases (SARDs). The standard test for antinuclear antibody screening is the indirect immunofluorescence (IIF). Anti-dense fine speckled 70 (anti-DFS70) antibodies were initially identified as an ANA IIF pattern from a patient with interstitial cystitis, but they were later associated with various other conditions. The objective of the study was to determine the frequency of anti-DFS70 antibodies in a cohort of patients undergoing routine ANA testing. Material and Methods: From January 2011 to January 2012, a total of 5800 serum samples were screened for ANA by IIF (Euroimmune AG, Lübeck, Germany). DFS pattern was searched. Results: ANA were present in 1302 (22.4%) of all patients. There were 16 (1.2%) anti-DFS70 antibody-positive patients. The number of females and males who have anti-DFS70 antibody was eleven and five, respectively. All of the samples presented a titer of ≥1/320. There was one patient with SARD from the rheumatology department. Another 15 patients were from gastroenterology, endocrinology, and general internal medicine. Conclusion: Although a distinctive clinical association has not been reported, anti-DFS70 have been proposed as a significant biomarker for the exclusion of SARD. The present study is a preliminary study. There is a need for a reliable assay to ensure reactivity to DFS70 and screening large populations

Özet

Amaç: Intraselüler antijenlere karşı yönlendirilen anti-nükleer antikorların (ANS) varlığı, sistematik otoimmün romatolojik hastalıkların (SORH) ayırt edici bir özelliğidir. İndirekt immunofloresan (IIF) antinükleer antikor taraması için kullanılan standart yöntemdir. Anti-yoğun ince benekli 70 (anti-DFS70) antikorları ilk olarak, interstisyel sistiti olan bir hastanın ANAIIF paterni olarak tanımlanmışlardır. Fakat daha sonra çeşitli durumlarla ilişkilendirilmişlerdir. Bu çalışmanın amacı, rutin ANA testi uygulanan bir kohort hasta grubunda anti-DFS70 antikorlarının sıklığını belirlemektir. Gereç ve Yöntemler: Ocak 2011 ile Ocak 2012 tarihleri arasında, toplam 5800 serum örneği ANA açısından IIF (Euroimmune AG, Lübeck, Almanya) ile tarandı. DFS paterni araştırıldı. Bulgular: 1302 hastada (%22.4%) ANA tespit edildi. Anti-DFS70 antikor-pozitif hasta sayısı 16 (%1.2) olarak bulundu. Anti-DFS70 antikor bulunan kadın ve erkek hasta sayısı sırasıyla 11 ve 5 olarak tespit edildi. Tüm hastalar ≥1/320 titre değeri sergilediler. Romatoloji bölümünden SORH olan sadece bir hasta vardı. Diğer 15 hasta gastroenteroloji, endokrinoloji ve genel dahiliye bölümlerindendiler. Sonuç: Ayırt edici klinik bir ilişki henüz bildirilmemiş olsa da, anti-DFS70in SORHun dışlanması için önemli bir biyobelirteç olduğu ileri sürülmüştür. Mevcut çalışma bir ön çalışmadır. DFS70 reaktivitesini sağlamak ve büyük popülasyonları taramak için güvenilir bir analize ihtiyaç vardır.
