Abstract

Background/aims: Hepatitis C virus leads to chronic liver disease, cirrhosis and hepatocellular cancer. Viral markers and other laboratory tests used in the diagnosis and follow-up of chronic hepatitis C do not correlate well with disease activity and liver histopathology. Therefore, alternative tests that indicate disease activity and relate with liver biopsy findings are needed. We aimed to investigate the relationship between serum complement levels and biopsy findings in patients with chronic hepatitis C. Methods: One hundred cases (70 patients, 30 healthy controls) were included in the study. Patients were divided into two groups: chronic hepatitis C patients with high transaminase levels were evaluated as the first group and patients with normal transaminase levels as the second group. Patients with a high transaminase level were biopsied and activity scores were evaluated against complement C3c and C4 levels. In addition, demographic data and laboratory tests were evaluated. Patients with chronic hepatitis C without proteinuria, acute phase response, cirrhosis, or coinfection with another hepatitis virus were included in the prospective study. Results: Serum complement C3c (p<0.01) and C4 (p<0.01) levels were significantly lower in the first group than the second group. Serum complement C3c levels did not correlate with laboratory tests, hepatitis C virus-RNA levels, histological activity index, or fibrosis scores in patients with high transaminase levels, whereas complement C4 levels showed significant correlation with alanine aminotransferase (r: -0.368, p: 0.001) and histological activity index (r: -0.639, p: 0.001). We could not find any relation between serum complement C4 level and fibrosis. Conclusions: Serum complement C4 levels correlate with the histological activity index of the Knodell scoring system.

Özet

Amaç: Hepatit C virusu kronik karaciğer hastalığı, siroz ve hepatoselluler kansere neden olmaktadır. Kronik hepatit C’nin tanı ve takibinde kullanılan viral marker ve laboratuvar testleri hastalığın aktivitesi ve karaciğer histopatolojik bulgularıyla iyi korelasyon gostermemektedir. Buna ba.lı olarak karaciğer biyopsi bulguları ve hastalık aktivitesi ile uyumluluk gosteren testlere gereksinim vardır. Bu calışmada kronik hepatit C hastalarında, serum kompleman duzeyi ile biyopsi bulguları arasındaki ilişkiyi araştı rmak istedik. Yöntem: Yuz olgu (70 hasta ve 30 sağlıklı kontrol) calışmaya alındı. Hastalar birincisi, yuksek transaminazlı kronik hepatit C hastaları ve ikincisi, normal transaminazlı kronik hepatit C hastaları olmak uzere ikiye ayrıldı. Yuksek transaminazlı hastalara biyopsi uygulandı ve aktivite skorları ile C3c ve C4 arasındaki ilişki değerlendirildi. Ayrıca demografik veriler ve laboratuvar testleri de.erlendirildi. Bu calışmaya proteinuri, akut faz yanıtı, siroz, di.er hepatit virusleri ile birlikteliği olmayan kronik hepatit C hastaları alındı. Bulgular: Serum kompleman C3c (p <0,01) ve C4 (p<0,01) duzeyleri birinci gurupta ikinci guruba gore anlamlı olarak daha duşuktu. Yuksek transaminazlı hastalarda serum kompleman C3c duzeyi laboratuvar testleri, hepatit C virusu-RNA duzeyleri, histolojik aktivite indeksi ve fibrozis skoru ile korelasyon bulunmadı. Kompleman C4 duzeyleri ile alanin aminotransferaz (r:-0,368 ve p:0,001) ve histolojik aktivite indeksi (r: -0,639 ve p:0,001) ile anlamlı korelasyon vardı. Serum kompleman C4 ile fibrozis arasında anlamlı bir ilişki saptanmadı. Sonuç: Serum kompleman C4 duzeyi Knodell skorlama sistemindeki histolojik aktivite indeksi ile korelasyon gosterir.
