Abstract

Background/aims: We aimed to evaluate the diagnostic accuracy of AST-platelet ratio index in the prediction of significant fibrosis and cirrhosis in chronic hepatitis B patients by comparison with liver biopsy. Materials and Methods: We retrospectively reviewed our computerized data of chronic hepatitis B patients who attended the Gastroenterology Clinic from 2004-2009. Treatmentnaive chronic hepatitis B patients who had undergone liver biopsy were included in this study. The degree of fibrosis was scored according to the Ishak staging system. Significant fibrosis was defined as F3-6 and cirrhosis as F5-6. AST-platelet ratio index was calculated based on the original studies. Tests results were compared between the groups F0-2 versus F3-6 and F0-4 versus F5-6. Results: Two hundred and fifty consecutive patients with chronic hepatitis B were included in this study. The area under the ROC curves of AST-platelet ratio index to predict significant fibrosis and cirrhosis were 0.779 and 0.781, respectively. Using cut-off values ≤0.5 and >1.5, significant fibrosis was excluded with a negative predictive value of 91.30% and sensitivity of 87.69% and predicted with a positive predictive value of 59.52% and specificity of 90.81% in 53.60% of patients. Using cut-off values ≤1 and >2, cirrhosis was excluded with a negative predictive value of 92.09% and sensitivity of 64.10% and predicted with a positive predictive value of 33.33% and specificity of 91.47% in 81.60% of patients. Conclusions: AST-platelet ratio index may be a useful noninvasive marker in the exclusion of both significant fibrosis and cirrhosis in patients with chronic hepatitis B. However, it is not accurate in the prediction of either significant fibrosis or cirrhosis.

Özet

Amaç: Kronik hepatit Bli hastalarda belirgin fibrozis ve sirozun belirlenmesinde AST-platelet oranı indeksinin tanısal güvenilirliğini karaciğer biyopsisi ile karşılaştırmalı olarak değerlendirmek. Yöntem ve Gereç: 2004-2009 yıllarında Gastroenteroloji Kliniğine kronik hepatit B tanısı ile başvuran hastaların bilgisayar kayıtlarını retrospektif olarak inceledik. Karaciğer biyopsisi yapılmış olan hiç tedavi olmamış kronik hepatit Bli hastalar çalışmaya alındı. Fibrozisin derecesi Ishak sistemine göre belirlendi. F3-6 belirgin fibrozis ve F5-6 siroz olarak kabul edildi. AST-platelet oranı indeksi orijinal çalışmalar esas alınarak hesaplandı. Test sonuçları F0-2 ile F3-6 olan gruplar ve F0-4 ile F5-6 olan gruplar arasında karşılaştırıldı. Bulgular: 250 kronik hepatit Bli hasta çalışmaya alındı. Belirgin fibrozis ve sirozun belirlenmesinde AST-platelet oranı indeksi için ROC eğrisi altında kalan alan sırası ile 0.779 ve 0.781 idi. ≤0.5 ve >1.5 sınır değerleri kullanıldığında hastaların %53.60ında belirgin fibrozis %91.30 negatif prediktif değer ve %87.69 sensitivite ile dışlandı, %59.52 pozitif prediktif değer ve %90.81 spesifite ile doğrulandı. ≤1 ve >2 sınır değerleri kullanıldığında hastaların %81.60ında siroz %92.09 negatif prediktif değer ve %64.10 sensitivite ile dışlandı, %33.33% pozitif prediktif değer ve %91.47 spesifite doğrulandı. Sonuç: Kronik hepatit Bli hastalarda AST-platelet oranı indeksi hem belirgin fibrozis hem de sirozun dışlanmasında güvenilir bir noninvaziv belirteçtir. Ancak belirgin fibrozis ve sirozun doğrulanmasında yeterince güvenilir değildir.
