Kronik Hepatit B hastalarında prekor/kor mutantlarının sıklığı.

Objective: In recent years, the presence of precore/core region mutations were uncovered by the examination of Hepatitis B Virus (HBV) deoxyribonucleic acid (DNA) that is isolated from patient samples with anti-HBe seroconversion without viral replication loss. In this study, the frequency of precore/core mutations were investigated on serum samples obtained from chronic hepatitis B patients. Methods: From a total of 100 samples 69 anti-HBe and HBV DNA positive, and 31 HBeAg and HBV DNA positive samples were analyzed in the study to determine the imitations with the INNO-LIPA method at the Serology laboratory. Statistical analyses were bone with, SPSS vll.5 and chi-square and variance analysis (ANOVA) tests were conducted. Results: The precore mutations were detected in 68, while the core promoter mutations were present in 57 samples. Mutations were detected at the precore region in 11 out of 31 HBeAg positive (35%), and 57 out of 69 anti-HBe positive samples (83%). Likewise, the core promoter region was affected in 10 of 31 HBeAg (32%), and 47 out of 69 anti-HBe positive samples (68%). Both precore and core promoter imitations were substantially higher in the anti-HBe positive group (p<0.05). Conclusion: As a result, since precore/core mutations were prevalent in samples obtained from the study group, it is our opinion that careful attention must be paid to such mutations during the diagnosis and treatment phases of chronic hepatitis B patients.
