All papers submitted to Gut and Liver are reviewed by the editorial team before being sent out for an external peer review to rule out papers that have low priority, insufficient originality, scientific flaws, or the absence of a message of importance to the readers of the Journal. A decision about these papers will usually be made within two or three weeks.
The remaining articles are usually sent to two reviewers. It would be very helpful if you could suggest a selection of reviewers and include their contact details. We may not always use the reviewers you recommend, but suggesting reviewers will make our reviewer database much richer; in the end, everyone will benefit. We reserve the right to return manuscripts in which no reviewers are suggested.
The final responsibility for the decision to accept or reject lies with the editors. In many cases, papers may be rejected despite favorable reviews because of editorial policy or a lack of space. The editor retains the right to determine publication priorities, the style of the paper, and to request, if necessary, that the material submitted be shortened for publication.

Background/Aims: Anti-hepatitis B virus (HBV) therapy is required for patients with HBV infection receiving biologics because of the high risk of HBV reactivation. However, it is unclear when to start biologics after anti-HBV treatment. We investigated the risk of HBV reactivation according to the timing of biologics initiation after anti-HBV treatment in immune-mediated inflammatory disease (IMID) patients with HBV infection.
Methods: We retrospectively evaluated the incidence of HBV reactivation in IMID patients who received biologics between July 2005 and April 2020. The patients were divided into two groups (within 1-week and after 1-week) according to the timing of biologics initiation after anti-HBV treatment. The cumulative probabilities and factors associated with HBV reactivation were evaluated.
Results: A total of 60 hepatitis B surface antigen-positive patients with IMID received biologics (within 1-week group, n=23 [38%]; after 1-week group, n=37 [62%]). During a median follow-up of 34 months (interquartile range, 20 to 74 months), three patients (5%) developed HBV reactivation. In univariate analysis, the timing of biologics after anti-HBV treatment was not significantly associated with the risk of HBV reactivation (hazard ratio, 0.657; 95% confidence interval, 0.059 to 7.327; p=0.733). The cumulative probabilities of HBV reactivation did not significantly differ according to the timing of biologics (p=0.731).
Conclusions: The risk of HBV reactivation was not significantly associated with the timing of biologics administration after anti-HBV treatment. Thus, biologics may be initiated early in patients with IMID undergoing treatment for HBV.
