Abstract

Background/aims: Oxygen free radicals have an important role in the pathogenesis of acute and chronic liver disease. Free radical formation and oxidative damage, probably mediated with copper accumulation, are important in Wilson's disease pathogenesis. This study was performed to determine if accumulating copper in Wilson's disease is a cause of further oxidant stress compared to non-Wilsonian liver disease. Methods: In this study, we investigated plasma malondialdehyde and nitric oxide levels to estimate the oxidant stess and total antioxidant capacity and vitamin E/cholesterol, vitamin C and b-carotene levels to estimate the antioxidant status of patients. The groups investigated included 24 patients with Wilson's disease (group I), 25 patients with non-Wilsonian chronic liver disease (group II) and 23 healthy controls (group III). Wilson's disease and non-Wilson's disease patients were divided into subgroups according to disease stage (i.e. chronic hepatitis and cirrhosis) and all parameters were compared between subgroups and controls. Results: Malondialdehyde and nitric oxide levels were higher than controls in groups I and II (p=0.013, p=0.01), but these levels did not differ between the Wilson's disease and non-Wilson's disease groups. The parameters were also evaluated with respect to the disease stage (i.e. chronic hepatitis and cirrhosis), and there was no difference between groups I and II. Although malondialdehyde and nitric oxide levels were significantly different between both disease stage groups and the controls, we observed decreased vitamin C and b-carotene levels only in cirrhosis stage (p=0.01, p=0.01). Conclusions: We observed the presence of oxidant stress unrelated to the etiology of the liver disorder in our study. Deficiency of the major antioxidants, vitamin C and b-carotene, develops as the disease stage advances from chronic hepatitis to cirrhosis.

Özet

Amaç: Akut ve kronik karaciğer hastalığının patogenezinde serbest oksijen radikallerinin önemli rolü vardır. Wilson hastalığının patogenezinde biriken bakır aracılığı ile oluşan oksidatif hasarın rolü önemlidir. Bu çalışmada Wilson hastalığında biriken bakırın wilson dışı kronik karaciğer hastalıklarında oluşan oksidatif strese ek bir oksidatif stres oluşturup oluşturmadığı araştırılmıştır. Yöntem: Bu çalışmaya çocukluk yaş grubunda 24 Wilson hastası (grup I), 25 Wilson dışı kronik karaciğer hastası (grup II) ve 23 sağlıklı çocuktan oluşan kontrol grubu alınmıştır (grup III). Tüm gruplarda oksidan stresin değerlendirilmesi amacı ile plazma malondialdehit ve nitrik oksit, antioksidan durumu değerlendirmek amacı ile total antioksidan kapasite, vitamin C, beta karoten ve vitamin E/kolesterol oranı ölçülmüştür. Karaciğer hastaları hastalıklarının hepatit veya siroz evresinde oluşuna göre yeniden gruplanarak aynı parametreler açısından karşılaştırılmışlardır. Bulgular: Malondialdehit ve nitrik oksit düzeyleri grup I ve II de sağlıklı kontrollerden anlamlı oranda yüksek bulundu. Grup I ve II de kronik hepatit ve siroz olguları arasında oksidan stres ve antioksidan durum göstergeleri açısından fark saptanmadı. Malondialdehit ve nitrik oksit düzeyleri heriki hastalık grubunun heriki evresinde de kontrol grubundan yüksek bulundu. Vitamin C ve beta karoten düzeyleri ise sadece siroz evresinde kontrol grubundan anlamlı oranda düşüklük gösterdi. Sonuç: Bu sonuçlarla çocukluk çağı kronik karaciğer hastalığının patogenezinde etyolojiden bağımsız olarak oksidatif stresin rol oynadığı ve anti-oksidan vitaminlerden özellikle C vitamini ve beta karotenin hastalığın siroz evresinde düşüş gösterdiği belirlenmiştir.
