Abstract

The aim of the study was to detect CD4 and CD8 T-lymphocyte counts of patients with severe pulmonary tuberculosis (TB) and compare these parameters in patients with mild pulmonary TB and healthy controls. Twenty HIV (-), severely ill patients with pulmonary TB, 20 HIV (-), mildly ill patients with pulmonary TB, and 20 healthy people were included in the study. T-lymphocyte subgroups (CD4+ and CD8+) were detected by şow cytometry in all groups before and three months after the treatment for both TB groups. In severely ill group, CD4+ T-lymphocytes (269±101/$mm^3$) were found to be decreased when compared those of mildly ill group (596±205/$mm^3$) and healthy controls (714±174/$mm^3$) (p<0.001). In severely ill group, CD4/CD8 ratios were lower than those in mildly ill and healthy controls (p<0.01). Three cases in severely ill group died due to uncontrolled disease. In severe pulmonary TB cases, CD4+ T-lymphocytes and CD4/CD8 ratio may fall and such abnormalities in Tlymphocytes may improve with appropriate treatment.

Özet

Çalışmamızda genel durumu kötü HIV (-) akciğer tüberkülozlu hastaların kandaki CD4 ve CD8 T lenfosit sayılarını tespit etmek ve bu değerlerin genel durumu iyi olgularla karşılaştırılması amaçlanmıştır. Çalışmaya, HIV(-) akciğer tüberkülozlu genel durumu kötü 20, genel durumu iyi 20 ve sağlıklı 20 olgu alınmıştır. Hastaların tedavi öncesi ve tedavinin 3. ayı, gönüllülerin ise tedavi öncesinde periferik kanlarında akım sitometrisi yöntemiyle T lenfosit altgrupları sayısal olarak incelenmiştir. Genel durumu kötü olan olgularda CD4+ T lenfosit sayısının (269±101/$mm^3$), genel durumu iyi olan olgulara (596±205/$mm^3$) ve sağlıklı gönüllülere (714±174/$mm^3$) göre azaldığı belirlenmiştir (p <0.001). Genel durumu kötü olan olguların CD4/CD8 oranları, genel durumu iyi olan olgulara ve sağlıklı gönüllülere göre düşük bulunmuştur (p <0.01). Genel durumu kötü olan olgulardan 3'ü hastalığın ilerlemesiyle yaşamını yitirmiştir. Sonuç olarak, genel durumu kötü akciğer tüberkülozunda CD4+ T lenfosit sayısı ve CD4/CD8 oranı düşebil - mekte ve başarılı bir tedavi ile T- lenfositlerdeki anormallikler düzeltilebilmektedir.
