ABSTRACT
The aim of this study was to evaluate the impact of insulin resistance on the persistence of a protective level of anti-HBs (hepatitis B surface antigen) in a nondiabetic general population. A cohort study was designed comprising of 38 473 Korean men and women with anti-HBs at concentrations ≥10 mIU/mL, who underwent a health examination. Insulin resistance was assessed with a homoeostasis model assessment of insulin resistance (HOMA-IR). A decline in anti-HBs to <10 mIU/L during the follow-up was considered to be a loss of protective anti-HBs. Cox-proportional hazard models were used to estimate the adjusted hazard ratios and 95% confidence intervals for anti-HBs loss across quintiles of HOMA-IR and insulin. We identified 20 826 incidents of loss of anti-HBs antibody during 180 522 person-years of follow-up (incident rate 11.5 per 100 person-years). Increasing HOMA-IR was positively associated with incident loss of anti-HBs. The multivariable-adjusted hazard ratios (95% confidence intervals) for incident loss of anti-HBs comparing quintiles 2-5 vs quintile 1 of HOMA-IR were 1.09 (1.04-1.14), 1.14 (1.09-1.19), 1.14 (1.09-1.19) and 1.21 (1.16-1.27), respectively. These associations were stronger in younger individuals under the age of 35 than in people 35 years of age or older (P for interaction = 0.004). The association was also more evident in subjects with higher titres (≥100 mIU/mL) of anti-HBs than in those with low titres (P for interaction < 0.001). Insulin resistance was associated with an increased risk for loss of vaccine-acquired anti-HBs in a large sample of a nondiabetic, general population, indicating a possible role of insulin resistance in vaccine-induced immunity.
