Association between hepatitis B virus infection and the incidence risk of chronic pancreatitis / 中华胰腺病杂志

ABSTRACT

Objective To investigate the correlation of previous hepatitis B virus (HBV) infection with the incidence risk of chronic pancreatitis (CP).Methods This was a case control study.Five hundred and seventy-one patients with CP admitted in the Department of Gastroenterology, Changhai Hospital, Second Military Medical University between January 2015 and October 2016 were enrolled, and 1216 sex and age matched health individuals were also enrolled as the control group.The 5 serum HBV markers(HBsAg,HBsAb, HBeAg, HBeAb and HBcAb) were detected and their correlation with CP incidence was analyzed.Results The positive rate of HBsAg in the CP group and the control group were 3.0% and 3.8%, respectively, and the difference was statistical significant.(OR=0.039, 95% CI 0.02~0.80, P0.05).The positive rate of HBeAb in the CP group and the control group were 24.3% and 10.8%, respectively, and the difference was statistical significant(P<0.00).The positive rate of HBcAb in the CP group and the control group were 50.1% and 16.5%, respectively,and the difference was statistical significant(P<0.000).In the(HBsAb+, HBeAb+, HBcAb+), (HBsAb+, HBcAb+), (HBeAb+, HBcAb+), (HBcAb+) models, the positive rate in CP group was significantly higher than that of the control group(P<0.000).Multivariate regression analysis showed that the positivity of HBsAb and HBeAb were the protection factors for the occurrence of CP(P<0.05),and HBcAb positivity was the independent risk factor for CP (OR=6.931,P<0.000).Conclusions HBsAb and HBeAb poitivity were the protectors for CP, while HBcAb positivity could be considered as an independent risk factor for CP.
