Abstract

Objective: The balance between the bacillus and host defense mechanisms seems to be important for manifestations of tuberculosis infection. Not only subtypes of T-lymphocytes but their activation status also is important in the immunity of tuberculosis infection. The aim of this study is to address the relationship between T-lymphocyte subtypes, activation and natural killer cells with different clinical forms of mycobacterium tuberculosis infection. Material and Method: Twenty-one active pulmonary tuberculosis, 10 inactive pulmonary tuberculosis, 10 tuberculous pleurisy patients and 18 healthy subjects were involved in the study. Immunophenotyping was carried out in peripheral blood for T cell subtypes, natural killer cells and B cells by flow-cytometry, and HLA-DR and CD25 positivity were studied to determine T-lymphocyte activation. Results: The CD4+ T lymphocyte rates was found significantly lower in bilateral active pulmonary tuberculosis compared to healthy controls. T-lymphocyte activation was found to be increased in tuberculous pleurisy cases. The CD3/CD25+ T lymphocyte rate was sinificantly higher in tuberculous pleurisy cases compared both to healthy controls and inactive pulmonary tuberculosis cases. Conclusion: CD4+ T-lymphocyte rate may be decreased in pulmonary tuberculosis patients with bilateral pulmonary infiltration. Prominent T-lymphocyte activation in tuberculous pleurisy might be a result of a hypersensitivity reaction against the bacillus. (Tur Toraks Der 2012; 13: 1-5)

Özet

Amaç: Tüberküloz enfeksiyonunun ortaya çıkan bulgularında basil ile konakçının savunma mekanizmaları arasındaki denge önemlidir. Tüberküloz enfeksiyonunun immünitesinde T lenfositlerin alt grupları kadar aktivasyon durumları da önemlidir. Bu çalışmanın amacı Mikobakterium tüberkülozis enfeksiyonunun farklı klinik formları ile T lenfosit alt grupları, aktivasyonu ve natural killer hücreler arasındaki ilişkinin araştırılmasıdır. Gereç ve Yöntem: Yirmi bir aktif pulmoner tüberküloz, 10 inaktif pulmoner tüberküloz, 10 tüberküloz plörezi hastası ve 18 sağlıklı kontrol olgusu çalışmaya dahil edildi. Periferik kanda immün fenotiplendirme yapılarak T hücre subgrupları, natural killer hücreler ve B hücreler için flowsitometri ve T lenfosit aktivasyonunun gösterilmesi için HLA-DR ve CD25 pozitifliği çalışıldı. Bulgular: Bilateral aktif pulmoner tüberkülozlu hastalarda kontrol grubuna göre CD4+ T lenfosit oranları anlamlı olarak düşük bulundu. Tüberküloz plörezili hastalarda T lenfosit aktivasyonunun artmış olduğu saptandı. CD3/CD25+ T lenfosit yüzdesi tüberküloz plörezili hastalarda hem sağlıklı kontrollere hem de inaktif pulmoner tüberkülozlu olgulara göre istatistiksel anlamlı olarak artmış bulundu. Sonuç: İki taraflı parankimal infliltrasyonu olan pulmoner tüberkülozlu hastalarda CD4 T lenfosit yüzdeleri düşebilmektedir. Tüberküloz plörezili hastalarda belirgin T lenfosit aktivasyonunun gösterilmesi basile karşı hipersensitivite reaksiyonunun sonucu olabilir. (Tur Toraks Der 2012; 13: 1-5)
