Abstract:
Objective To investigate the association between neutrophil-to-lymphocyte ratio (NLR) and the state of sustained immune response after hepatitis B vaccination, to explore the possibility to predict the effect of hepatitis B vaccination.Methods Data were analysed from 10 153 individuals aged 18 years and older who had received three doses of hepatitis B vaccine and met the inclusion criteria in the National Health and Nutrition Examination Survey (NHANES) 1999-2018. They were divided into seropositive and seronegative groups based on the results of post-vaccination hepatitis B marker testing. The association between NLR and sustained immune response status after hepatitis B vaccination was assessed using a variety of methods, including multivariate weighted logistic regression models, generalised linear analysis, and smoothed curve fitting.Results This study included 10 153 subjects with a mean age of 35.36 years, 42.82% male and 57.18% female. Adjusted multivariate weighted logistic regression models showed that for each unit increase in NLR level, the odds of a sustained immune response after hepatitis B vaccination decreased by 7% (OR=0.93, 95%CI: 0.88-0.97). Stratified analysis of NLR levels showed that the odds of a sustained immune response were 37% lower in the group with the highest NLR levels (T4) compared with the lowest group (T1) (OR=0.63, 95%CI: 0.47-0.85), and the odds of a sustained immune response were 30% lower in the T3 group compared with the T1 group (OR=0.70, 95%CI: 0.53-0.91). Restricted cubic spline analysis showed a non-linear relationship between NLR and sustained immune response status after hepatitis B vaccination (P non-linear<0.05), approximating an 'L' curve. Inflection point analysis showed that when NLR <2.16, elevated NLR significantly reduced the occurrence of sustained immune response status after hepatitis B vaccination; when NLR >2.16, the effect of its elevation on the production of sustained immune response after vaccination leveled off.Conclusion NLR levels were negatively associated with the development of a sustained immune response after hepatitis B vaccination. Lower NLR levels have a strong positive correlation with sustained immune response after hepatitis B vaccination, whereas higher NLR levels may attenuate the effect of hepatitis B vaccination.
