Comparison of Rate of Infection during Hydroxyapatite and Allogenic Bone Graft Used In Jaw Cyst: A Randomized Clinical Trial

Background: The course of hepatitis B virus (HBV) infection is not only determined by variations in viral virulence but may be influenced by host immune response, where Human Leukocyte Antigen (HLA) plays an important role. Objective: The purpose of the present study was to explore whether HLA-DRB13* allele of MHC gene had any influence in spontaneous recovery from HBV infection among Bangladeshi adults. Method: This cross sectional study was carried out at the Department of Virology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka Bangladesh. A total of 90 randomly selected hepatitis B virus infected adult patients, consisting of 30 acute HBV infections, 30 chronic HBV infection and 30 healthy controls were selected according to selection criteria for evaluation of HLA DRB1*13 allele. Detection of HLA DRB1*13 allele was done by conventional PCR followed by agarose gel electrophoresis. Result: The study revealed a significant increase of DRB1*13 in acute hepatitis B (AHB vs HC-40% vs 6.7%, RR= 9.4; P value 0.05). This is the first report on HLA DRB1* gene associations among hepatitis B (HBV) infected Bangladeshi patients. Conclusion: The present study revealed that HLA DRB1*13 was associated with protection against persistent HBV infection among acutely infected adult HBV patients in Bangladesh.
