Nonimmunity against hepatitis B virus infection in patients newly diagnosed with inflammatory bowel disease
This issue chosen by the Editor of Intestinal Research is a population based case-control study of the prevalence of hepatitis B virus (HBV) serologic markers in patients who were newly diagnosed with treatment-naïve IBD performed using registry of Crohn’s and Colitis Association in Daegu-Gyeongbuk district of Korea.

This study reported a 3.8% HBs-Ag-positivity rate and a 30.0% anti-HBc-positivity rate in Korean patients newly diagnosed with IBD. In this study, the prevalence of chronic HBV infection (positive HBsAg, positive anti-HBc, and negative anti-HBs results) and past infection (negative HBsAg, positive anti-HBc, and positive or negative anti-HBs results) were similar between IBD patients and healthy control.

Nonimmunity against HBV infection (negative HBsAg and negative anti-HBc results and anti-HBs level of <10 mIU/mL) was higher in IBD patients compared with healthy control (P<0.001). The IBD patients with the age of <20 years at the time of diagnosis and symptom duration of ≥ 12 months before diagnosis were at a higher susceptibility risk for nonimmunity against HBV infection.
