Study on occurrence of Hepatitis B virus Genotypes at a tertiary care hospital in Jaipur

: The hepatitis B virus's (HBV) capability to mutate genetically poses a threat to the sensitivity of serological and genomic diagnostics. As a result the knowledge about the distribution of HBV genotypes (GENs) and mutation has a significant impact on treatment plans, immunisation campaigns, treatment, and prophylaxis of HBV. : The objective of our study was to identify HBV Genotypes in HBsAg-positive individuals. : The study was conducted on 117 HBsAg-positive patients who showed the presence of the S gene were subjected to DNA extraction. The extracted DNA was amplified by Nested PCR (Polymerase Chain Reaction) followed by RFLP (Restriction fragment length polymorphism). : Out of 117 patients, 84% were genotype D and 16 % were genotype A. More patients of Genotype A had a fever and Jaundice (15.7%; 21 vs 5%; 13.2%) as compared to Genotype D. In this study 19.6% of patients were in the immune clearance phase, 18% in the inactive carrier, 6% in immune tolerance phase. : A better understanding of the prevalence, diagnostic, and serologic patterns of hepatitis B in this region can aid practitioners in recommending appropriate antivirals by genetic data.
