Abstract

Background/aims: T cell immunoregulatory cytokines may play a crucial role in the host response to hepatitis C virus infec-tion. While T-helper type 1 cytokines are required for host antiviral immune responses, T-helper type 2 cytokines can inhibit the development of these effector mechanisms. The aim of the present study was to determine T-helper type I and T-helper type 2 cytokine levels in chronic hepatitis C infection. Methods: Serum levels of T-helper type 1 cytokine, interferon-gamma (IFN-Y), and T-helper type 2 cytokines, IL-4 and IL-10 were measured in 30 patients with hepatitis C infection and 25 healthy controls using ELISA. Serum levels of alanine transaminase were also assessed in both patients and controls. Histologie activity score was evaluated in the chronic hepatic C infected patients. Results: Serum levels of IFN-j were 59.03+46.24 pg/mL, IL-4 were 213.59±135.67 pg/mL and IL-10 were 106.73±60.85 pg/mL in hepatitis C infected patients whereas in healthy controls they were found to be 61.84±54.87 pglmL, 67.39±59.74 pg/mL and 60.14±50.73 pglmL respectively. Serum levels of IL-4, IL-10 but not IFN-ywere found to be significantly increased in chronic HCV patients compared to those of control subjects. Conclusions: Our findings may suggest the involvement of Th2 cytokines in the pathogenesis of chronic hepatitis C virus liver disease.

Özet

Amaç: T hücre regülatuvar sitokinleri, vücudun hepatit C virüs infeksiyonlarına karsı geliştirdiği yanıtta önemli rol oynayabilirler. Yardımcı T hücre tip l sitokinleri, vücudun antiviral immün yanıtı için gerekli iken yardımcı T hücre tip 2 sitokinleri, bu etken mekanizmaların gelişimini inhibe edebilirler. Bu çalışmanın amacı, kronik HCV infeksiyonlarmda yardımcı T hücre tip l ve 2 sitokinlerinin düzeylerini belirlemektir. Yöntem: Yardımcı T hücre tip l sitokinlerinden Interferon (IFN)-gamma ve yardımcı T hücre tip 2 sitokinlerinden IL-4 ve IL-10 düzeylerine kronik hepatit C virüs infeksiyonu olan 30 hastada ve 25 sağlıklı kontrolde ELISA yöntemi ile bakıldı. Hasta ve kontrollerde, serum alanin transaminaz (ALT) düzeyleri de ölçüldü. Hasta grubunda, histolojik aktivite skoru değerlendirildi. Bulgular: Hepatic C virüs ile inpekte hasta grubunda serum IFN-gamma düzeyleri 59.03±46.24 pglmL, IL-4 düzeyleri 213.59+135.67 pg/mL, IL-10 düzeyleri 106.73±60.85 pglmL olarak bulunurken aynı sitokinlerin düzeyi sağlıklı kontrol grubunda sırası ile 61.84+54.87 pg l mL, 67.39±59.74 pglmL, 60.14±50.73 pglmL, olarak saptandı. Serum IL-4 ve IL-10 düzeyleri sağlıklı kontrol grubuna göre anlamlı olarak yüksek bulunurken, her iki grubun IFN-gamma düzeyleri arasında anlamlı fark saptanmadı. Sonuç: Bulgularımız, kronik hepatic C virüs infeksiyonunun patogenezinde yardımcı T hücre tip 2 sitokinlerinin yer aldığını düşündürtmektedir.
