Abstract

AIM: T lymphocytes, which are responsible for cellular immunity, are chief cells in specific antibody response against antigens. Approximately, 60% of these circulating T cells are CD4+ (T-helper) and 30% are CD8+ (T-suppressor). While stress, fatigue and corticosteroids have negative impact on their activation, exercise and some viral infections increase their activity. It was shown that percutaneous translüminal coronary angioplasty induced ischemia causes changes in circulating CD4+ and CD8+ cell percentages. PURPOSE: In this study, we aimed to determine the exercise induced changes of lymphocyte subtypes in patients with coronary artery disease (CAD). METHOD: We studied 31 patients with 50% or more stenosis of at least one major coronary vessel on coronary angiography (14 women, mean age: 56±6). Control group consisted of 10 patients (5 women, mean age: 50±9) with low likelihood of CAD and negative treadmill test in whom coronary angiography was considered to be unnecessary. Lymphocyte subsets were investigated in the resting stage, immediately and 24 hours after exercise. RESULTS: In both groups number of leucocytes and lymphocytes were significantly increased after exercise and returned to basal values after 24 hours. For the patient group, CD4+ T lymphocytes did not change immediately after exercise but increased significantly 24 h after exercise (P< 0.05). However, CD8+ T lymphocytes were significantly increased after exercise and returned to basal values after 24 hours in CAD group (39±11% vs 31±10, P<0.01). CONCLUSION: In conclusion, in patients with CAD, physical exercise induces increase in CD8+ T lymphocyte subset. This may be due to changes of immune function in patients with CAD and suggests immune system mediated inflammatory nature of ischemic syndromes. Further studies are needed to determine the place of lymphocyte subset analysis in the evaluation of exercise test.

Özet

AMAÇ: T lenfositler hücresel bağışıklıktan sorumlu olup, antijen spesifik antikor cevabının oluşmasında esas hücrelerdir. Periferde dolaşan T lenfositlerin %60'ı CD4+ (T-helper), %30'u CD8+ (T-supressor) hücrelerdir. Stres, yorgunluk ve kortikosteroidler bunların aktivitesini olumsuz yönde etkilerken egzersiz ve bazı viral enfeksiyonlar bu hücrelerin aktivitesini artırmaktadır. Perkütan translüminal koroner anjiyoplasti ile oluşturulan iskemi esnasında lenfosit alt gruplarının incelenmesinde CD4 ve CD8 seviyelerinde değişiklik olduğu gösterilmiştir. Bu çalısına, koroner arter hastalığı (KAH) olanlarda, egzersiz ile lenfosit alt gruplarında oluşan değişiklikleri araştırmak amacıyla yapıldı. YÖNTEM: Çalışmaya koroner anjiografilerinde majör koroner arterlerin en az birinde %50 ve üzerinde darlık bulunan ve yaş ortalaması 56±6 yıl olan I4'ü kadın 31 olgu alındı. Kontrol grubunu ise koroner anjiografi endikasyonu olmadığı kanısına varılan, yaş ortalaması 50±9 yıl olan. treadmil testi negatif 5 'i kadın 10 olgu oluşturdu. Lenfosit alt grupları egzersiz öncesi ile hemen sonrasında ve testten 24 saat sonra tespit edildi. BULGULAR: Her iki grupta da lökosit ve lenfosit sayısında egzersiz öncesine göre anlamlı bir yükselme olup 24 saat sonra bu değerlerde bazal değerlere dönüş saptandı. Hasta grubunda, CD4+ T-lenfosit sayısında egzersiz hemen sonrasında istatiksel olarak anlamlı değişiklik olmamakla birlikte 24 saat sonrasında anlamlı artış gözlendi (P<0.05). CD8 T lenfosit düzeyleri kontrol grubunda istatiksel olarak anlamlı düzeyde yükselmezken KAH olanlarda egzersiz hemen sonrasında öncesine göre anlamlı artış (%31±10 'a %39±11. P<0.01) saptandı. SONUÇ: Sonuç olarak, KAH olanlarda fizik egzersiz ile CD8+ T lenfosit alt grubunda artış olmuştur. Bu KAH' lı hastalarda immün fonksiyondaki değişikliğe ve iskemik sendromların immün sistem aracılığıyla oluşan inflamatuar yapısına bağlanabilir. Lenfosit alt grup analizinin egzersiz testindeki yerinin belirlenmesi için daha ileri çalışmalara gereksinim vardır.
