Abstract

Background/aims:Immune-modulator and antiviral treatments for carriers of hepatitis B virus are knoum to have poor efficacy with a high cost and frequent side effects, which has led to investigation of new treatment modalities. The aim of this study ıvas to determine the efficacy of recombinant hepatitis B vaccine in the treatment of patients with chronic hepatitis B (HBV DNA>5 pg / mi, ALT>60) infection diagnosed histopathologically and asymptomatic carriers (HBV DNA<5 pg / mi, ALT <40, Anti Hbepositive) of the virus. Methods: The vaccine (Gen Hevac B Pasteur) ıvas administered at baseline and at months öne and six to patients with chronic hepatitis and asympto-matic carriers. Ten cases ıvith chronic hepatitis B infection ıvere assigned to a control group to whom no treatment was given. Biochemical and microbiological investigations were performed at baseline and at months three, six and twelve in ali cases. Seroconversion of Hbe Ağ, loss of HBV DNA and nor-mallzation of ALT were considered as a positive response. Results: Patients ıvith chronic hepatitis B who were given the vaccine ıvere found to have significantly low levels of HBV DNA at 12 months (63.2±20pg / mi) compared to baseline values (174.4±36.9pg/ml), vjhile controls were found to have high lev-els of HBV DNA at 12 months (223.1±33pg/ml) compared to baseline values (165.2±33.2pg / mi) (p<0.05). At 12 months, HBV DNA had 'become negative in seven of 19 patients given the vaccine (36.8%) Four patients ıvith chronic hepatitis (36.35%) vjere observed to have HBeAg seroconversion and öne patient (5.2%) HBsAg seroconversion at the end of 12 months and there ıvere four (21.05%) patients ıvho responded positive-ly to vaccine therapy in this group. Asymptomatic carriers and controls did not have seroconversion of HBs Ag. Also, HBV DNA did not become negative in controls. Conclusion: it may be concluded that recombinant hepatitis B vaccine is effective in the treatment of chronic hepatitis B.

Özet

Amaç: Kronik hepatit tedavisinde denenen immünmodülatör ve antiviral tedavilerin etkinliklerinin istenen düzeylerde olmaması, bu tedavilerin yüksek maliyeti ve sık görülen yan etkilerinden dolayı HBV taşıyıcıları için tedavi arayışları sürmektedir. Bu çalışmanın amacı HBV enfeksiyonu sonrası kronik hepatit gelişen veya taşıyıcı olan olguların tedavisinde rekombinan hepatit B (rHB) aşı uygulamasının etkinliğini belirlemektir. Yöntem: Kronik hepatit tanısı alan 19 ve asemptomatik taşıyıcı olan 18 olguya 0,1 ve 6. ay olmak üzere üç defa 0.5 cc (Gen Hevac B Pasteur) rHB aşısı uygulandı. Kontrol grubu olarak kronik hepatit B tanısı alan 10 olgu tedavisiz izlendi. Olguların O, 3, 6 ve 12. ay da biyokimyasal, mikrobiyolojik tetkikleri ve HBV DNA düzeyleri çalışıldı. Hbe Ag serokonversiyonu, ALT normalleşmesi ve HBV DNA' nın kaybolması durumunda tedaviye pozitif cevap oluştuğu kabul edildi. Bulgular: Kronik hepatitli olguların 12. ay (63.2±20 pqlml) HBV DNA düzeylerinin 0. ay (174.4±36.9 pq/ml) düzeylerinden anlamlı düşük olduğu kontrol grubunda ise 12. ay (223.1+33 pq/ml) HBV DNA düzeylerinin 0. aydan (165.2±33.2 pq/ml) anlamlı yüksek olduğu gözlendi (p<0.05). Çalışma grubunu oluşturan 19 olgunun yedisinde HBV DNA' nın (%36.8) negatifleştiği, ALT nin normal düzeye indiği gözlendi. Kronik hepatitli olguların dördünde (%36.35) HBeAg serokonversiyonu, birinde ise (%5.2) Anti HBs oluşumu gözlendi. Bu olguların dördünde (%21.05) pozitif cevap oluştuğu gözlendi. HBV DNA' nın negatif olduğu taşıyıcı olgularda ve kontrol grubu olgularda HBs Ag serokonversiyonu gözlenmedi. Sonuç: Çalışmamız sonuçlarına göre rHB aşısı kronik hepatit B tedavisinde etkili bir tedavi yöntemi olarak düşünülebilir.
