Abstract

Background/aims: Effective hepatitis B virus control has warranted a decline in hepatitis B virus prevalence over the world with a relevant reduction in hepatitis B virus-associated delta hepatitis. However, despite the dramatic decline in hepatitis D virus infection rate, no further decrease was recorded after 2000. This cross-sectional study aims to investigate: I- The prevalence of hepatitis D virus co-infection in children with hepatitis B virus infection in Western Turkey; II- The influence of neonatal hepatitis B virus vaccination on hepatitis D virus co-infection rate; and III- The impact of co-infection on prognosis of liver disease. Materials and Methods: Serological markers of hepatitis B virus and hepatitis D virus infections were determined by ELISA in patients with chronic hepatitis during immune tolerance, immunoactive, HBeAg-negative chronic, and inactive carrier state. Delta co-infection rate was evaluated in two groups, children born before and after the national neonatal mass vaccination has started (before and after 2000). Viral load, serum alanine aminotransferase, and histological grade were evaluated in co-infected cases. Results: Overall hepatitis delta virus infection rate was 1,76% (3/170); two patients with eAg-negative chronic hepatitis B and one patient in the immunoactive phase were infected with hepatitis D virus. Mean fibrosis score of hepatitis D virus -infected cases and hepatitis B virus -infected counterparts were 4±1,7 and 1,3±1, respectively (p: 0,006). Hepatitis D virus infection was detected in 2 out of 158 children born before and in 1 of 12 born after the neonatal vaccination program. Hepatitis B e-antibody was detected in two patients with delta co-infection (11 and 6 years old), and all mothers of delta hepatitis cases were chronically hepatitis B virus-infected. Conclusions: Delta hepatitis is rare among hepatitis B virus-infected children in the Western region of Turkey. Despite the success of the national vaccination program, delta hepatitis is not a vanishing disease and it has a grave prognosis due to development of early cirrhosis.

Özet

Giriş ve Amaç: Hepatit B virüsünün kontrolü ile dünyada gerek hepatit B virüsü ve gerekse delta hepatiti prevalansında azalma sağlanmıştır. Ancak; ilk zamanlarda delta hepatiti sıklığında izlenen dramatik düşüş 2000'li yıllardan sonra izlenmemiştir. Bu ke- sitsel çalışmada şunlar hedeflenmektedir: I- Türkiye'nin batı bölgesinde hepatit B virüsü enfeksiyonlu çocuklarda delta hepatiti ko- enfeksiyon sıklığını belirlemek II- Yeni doğan hepatit B virüsü aşı programının delta hepatiti ko-enfeksiyon sıklığına etkisini belir- lemek III- Karaciğer hastalığının prognozu üzerine delta hepatiti'nin etkisini belirlemek. Gereç ve Yöntem: Kronik hepatit B virü- sü enfeksiyonunun immun toleran, immunoaktif, HBeAg negatif ve inaktif taşıyıcılık fazında olan olgularda hepatit B virüsü ve del- ta hepatiti serolojisi ELİSA yöntemi ile çalışıldı. Ulusal yeni doğan aşılamasından önce ve sonra doğanlar olmak üzere 2 grupta delta hepatiti ko-enfeksiyon sıklığı değerlendirildi. Viral yük, serum alanin aminotransferaz ve histolojik derecelendirme delta he- patiti ko-enfeksiyonu olan ve olmayan olgularda karşılaştırıldı. Bulgular: Tüm olgularda delta infeksiyonu sıklığı 1,76% (3/170) bulundu. HBeAg negatif kronik hepatitli 2 hasta ve immunoaktif 1 hastada delta hepatiti enfeksiyonu tespit edildi. Sadece hepatit B enfeksiyonu ve delta hepatiti dual enfeksiyonu olan hastalarda ortalama fibrosis skoru sırasıyla 1,3±1 ve 4±1,7 bulundu (p: 0,006). Hepatit delta sıklığı aşılama öncesi ve sonrası doğan çocuklarda sırasıyla, 2/158 (%1,2) ve 1/12 idi. Hepatit e antikoru (an- ti-HBe) delta hepatiti tespit edilen olguların 2'sinde pozitifti ve tüm çocukların annelerinde kronik hepatit B enfeksiyonu mevcuttu. Sonuç: Türkiye'nin batı bölümünde, hepatit B virüsü ile enfekte çocuklarda delta hepatiti sıklığı düşüktür. Ulusal aşı programına rağmen, delta hepatiti ortadan kaldırılamamıştır ve bu olgular erken yaşta siroza ilerlemektedir.
