Study on rhGM-CSF as adjuvant in revaccination among adults of non-and hyporesponders to hepatitis B vaccine / 中华实验和临床病毒学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effect of recombinant human granulocyte macrophage colony stimulating factor (rhGM-CSF) as adjuvant on immune response in adults of non-and hyporesponders to hepatitis B vaccine.</p><p><b>METHODS</b>Those who were once immunized with recombined yeast gene hepatitis B vaccine more than one standard scheme in two years and negative for hepatitis B markers were randomly sorted as group A and group B. 33 adults of group A were given hepatitis B vaccine 10 microg each time. The immune procedure was 0, 1 and 6 month. 34 adults of group B were given rhGM-CSF 300 microg for the first day, then 10 microg each time for routine immune. The blood samples were collected before the first injection and in 1, 2 and 8 months (T1, T2, T8) following the first injection to test Anti-HBs.</p><p><b>RESULTS</b>Anti-HBs positive conversion rates of group A and B at T8 was 39.39% and 64.71% respectively (P = 0.038). Anti-HBs levels of group B at T1, T2, T8 were (113.85 +/- 198.56) mIU/ml, (312.40 +/- 349.44) mIU/ml, (427.74 +/- 411.58) mIU/ml (P = 0.001). There was significant difference between group A and B in T8 Anti-HBs levels (P = 0.010).</p><p><b>CONCLUSION</b>Better immune response was found in the group of rhGM-CSF with hepatitis B vaccine. So rhGM-CSF can induce the immune respond to hepatitis B vaccine.</p>
