OBJECTIVES: To analyze the role of HLA genotypes in persistence of chronic hepatitis B in Western India. METHODS: HLA genotyping for class II-DR was done in 26 subjects having chronic hepatitis B infection (HBsAg positive) and in 100 healthy controls. Statistics were done using Halden's modification of Woolf's formula. RESULT: Significant association of chronic hepatitis B infection was found for class II-DR antigens DRB1*15XX (57.6 vs. 25%) and DRB1*11XX (23 vs. 4%). DRB1*13XX (0 vs. 19%) was negatively associated with chronic hepatitis B infection. CONCLUSION: HLA phenotype, which varies with different regions, is one of the factors in persistence of hepatitis B infection. Our study supports negative association of DRB1*13XX to persistence of HBV. Also there may be role of DRB1*11XX and DRB1*15XX in persistence of HBV and development of chronic HBV hepatitis.
