Abstract

Amaç: Bu çalışmadaki amacımız, lokalize provoke vulvodinisi (LPV) olan hastaların vestibular mukozasında, B lenfosit yoğunluğu ve germinal merkez varlığına bakılarak lokal immün aktivasyonun olup olmadığını araştırmaktır. Gereç ve Yöntem: LPV olup vestibülektomi ameliyatı geçiren 20 hastanın kolporafi posterior ameliyatı olan 20 kontrol hastanın vulvar vestibüler doku kesitleri incelenmiştir. B lenfositini göstermek için kullanılan CD20 antikoru ile yapılan immünohistokimyasal boyamayı takiben mikroskop altında B lenfosit yoğunluğuna ve germinal merkez varlığına bakılmıştır. Bulgular: Kontrol vakaların kesitleri ile kıyaslandığında, LPV olan hastaların vulvar vestibüler mukoza kesitlerinde B lenfosit yoğunluğu daha yüksek izlenmiştir (LPV hasta 87 vs kontrol hasta 21, p<0,01). Germinal merkez varlığı sadece LPV olan hastaların vestibüler mukoza kesitlerinde izlenmiştir (LPV hasta 0,31 vs kontrol hasta 0, p<0,011). Sonuç: LPV hastalığında, vestibüler mukozada artmış B lenfosit yoğunluğu ve beraberinde izlenen germinal merkez varlığı, lokal bir immün aktivasyonun olduğunu göstermektedir. Anormal germinal merkez cevabının olması durumunda, otoreaktif B lenfositleri ve bunun sonucunda otoimmün hastalıklar gelişebilmektedir. LPV’nin patofizyolojisinin ve otoimmünite ile ilişkisinin ortaya konmasında daha fazla sayıda çalışmaya ihtiyaç vardır.

THE ROLE OF B LYMPHOCYTES AND PRESENCE OF GERMINAL CENTERS IN PATIENTS WITH LOCALIZED PROVOKED VULVODYNIA

Abstract

Objective: The aim of the study is to assess local immune activation through B lymphocytes density and the presence of germinal centers in the vestibular mucosa of patients with localized provoked vulvodynia (LPV). Materials and Methods: Vestibulectomy specimens of 29 patients with LPV and colporrhaphy posterior specimens of 20 control women were included in the study. Immunohistochemical staining with CD20 antibodies for B lymphocytes were performed and subsequently, microscopical evaluation for B lymphocytes density and the presence of germinal centers was conducted. Results: B lymphocyte densities were higher in the vestibular mucosa of patients with LPV compared to control women (87 vs 21, p<0.01). The presence of germinal centers was only observed in the specimens of patients with LPV (0.31 vs 0, p<0.011). Conclusion: The presence of germinal centers with increased B lymphocyte density underlines a local immune activation in the vestibule of patients with LPV. An abnormal germinal center response can trigger the pathway to the development of autoimmunity through the emergence of an autoreactive B cell clone and autoantibodies. LPV can potentially emerge as an autoimmune disease of the vestibule. More studies are needed to understand the pathophysiology of LPV and its association with autoimmunity.
