Abstract

Background: Hepatitis B virus (HBV) which was acquired during perinatal or childhood would promote hepatocellular carcinoma with even higher percentage than that which was acquired during adult age. That is why HBV represents a serious public health threat for children. HBV vaccination has been integrated into national expanded programme on immunization (EPI) since 1997. The aimof they study is to investigate the prevalence of HBV among children who were born after 1997 in Sumenep. Material and Methods: a total of 102 children who were born after 1997 were enrolled in this study. All children were admitted in the Emergency Room and Pediatric Ward of dr. H. Moh Anwar General Hospital for some reasons. Written informed consents were obtained from parents/guardians of all the children. Study protocol was reviewed and approved by the Ethics Committees. All of these cases were examined for hepatitis B surface antigen (HBsAg), antibody to HBsAg (Anti-HBs), and antibody to hepatitis B core antigen (Anti-HBc). Result and Discussion: Overall, 6 (5.88%) of 102 samples were positive for HBsAg, 51 (50.00%) of 102 samples were positive for anti-HBs, and 49 (48.04%) of 102 samples were positive for anti-HBc. All the children were born after 1997. Conclusion: HBsAg rate is still high even after universal vaccination program, acquired protective antibodies against hepatitis B surface antigen were sufficient, but there is a suspicion for occult hepatitis B infections (OBI). A further study to confirm OBI is needed.

Abstract

Polymorphisms in TNF-α gene promoter region are known of its role in the production of TNF-α which may influences the pathogenesis of liver disease. SNPs in positions 238 and 308 of TNF-α gene promoters may affect the production of these cytokines. This study was aimed to detect Single Nucleotide Polymorphism (SNP) on -238 and -308 positions in the TNF-α gene promoter among liver cirrhosis patients with HBV infection in Surabaya, Indonesia. This was descriptive exploratory research with cross sectional study design using serum liver cirrhosis patients with HBV infection in Endoscopy Outpatient Clinic Dr. Soetomo General Hospital, Surabaya from April-May 2017. SNPs at -238 and -308 on TNF-α gene promoter (rs361525 and rs1800629 respectively) were detected using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) with primers specific for the TNF-α promoter region and restriction enzymes NcoI and MspI. The genotypes of TNF-α gene promoter were assessed according to the length of the fragments produced in RFLP. Serum TNF-α levels was measured by commercial ELISA. In this study, as much as 149 positive HBsAg patients was found in Endoscopy Outpatient Clinic, Dr. Soetomo General Hospital, Surabaya. From those amount, as much as 30 liver cirrhosis patients with positive HBsAg were obtained. From 2/30 (6.7%) patients showed the GA heterozygote SNP either position -238 or -308. No patient had the AA genotype. Median blood TNF-α level in women (38 ng / L) was higher than in men (33 ng / L). TNF-α levels in patients with GA heterozygote genotype at -238 and -308 in this research was not different than wild-type (GG genotype). Among patients with liver cirrhosis due to chronic HBV infection in Surabaya, Indonesia, Surabaya, we found GA polymorphisms the TNF-α promoter gene at positions -238 and -308 in 6.7% patients, and did not find homozygous AA polymorphisms. Further studies including larger numbers of patients from various ethnic backgrounds in Indonesia are needed to provide robust data on TNF-α gene promoter polymorphisms and their role in the pathogenesis of liver cirrhosis with HBV infection in this country.
