Abstract
AIMS:
Assess IBD patients starting anti-TNF for the impact of preventive measures in HBV and/or HCV, and the predictive response factors to HBV vaccination.
METHODS:
Multicenter prospective study including 389 IBD patients. Four interventions were established: I-1) anti-HBs <100IU/L: HBV vaccination with double doses at 0-1-2months, and revaccination if titres <100IU/L (seroprotection defined as anti-HBs10-100IU/L and effective vaccination anti-HBs >100IU/L); I-2) anti-HBs >100IU/L (previous effective vaccination): monitoring levels; I-3) anti-HBc and/or HCV+: analysis every two months; I-4) HBsAg+: start anti-virals.
RESULTS:
I-1 and I-2) For first vaccination, effective vaccination and seroprotection were obtained in 26.4% and 43.5%, and for revaccination 31.3% and 44.4%, respectively. Predictive factors of effective vaccination were age ≤30years (OR=2.2) and being vaccinated simultaneously with anti-TNF (OR=5.2) instead of late vaccination, whereas age ≤30years (OR=2.6) and anti-TNF monotherapy (OR=2.4) were predictive for seroprotection. 80.8% of patients previously vaccinated maintained titres at 29months follow-up. The only factor related to maintaining titres was previous vaccination versus achieving effective vaccination during anti-TNF (HR=2.49); I-3 and I-4) HBV-DNA + without reactivation was detected in 7% of 29 anti-HBc. No reactivation was found in the remaining HCV (n=5) or HBsAg (n=4) patients.
CONCLUSIONS:
1) Response to vaccination/revaccination is low in patients with anti-TNF. Young patients vaccinated at the beginning of anti-TNF and receiving it as a monotheraphy showed better response. 2) Long-lasting effective vaccination is greatest in patients previously vaccinated. 3) Following-up the established surveillance and/or preventive anti-viral therapy seems to be safe in HBV and HCV patients.
