ABSTRACT
OBJECTIVE:
We sought to determine the effect of treatment with topical tacrolimus on B- and T-cell immunity including the primary antibody response to pneumococcal polysaccharide vaccine in children with atopic dermatitis.METHODS:
In this open-label, noncomparative study, 23 children aged 2 to 12 years with moderate to severe atopic dermatitis were treated with tacrolimus 0.03% ointment twice daily for 7 weeks, immunized with a 23-valent pneumococcal polysaccharide vaccine after 3 weeks of treatment, and had their antibody response measured (for 12 pneumococcal serotype antigens present in the vaccine) before and 4 weeks after vaccination. None had received pneumococcal vaccine before the study. Patient antibody and cellular immune responses were assessed at each study visit (baseline, week 3, and week 7).RESULTS:
No significant changes in complete blood cell count, lymphocyte subsets, CD4/CD8 ratio, immunoglobulin levels, antibody titers to tetanus and Haemophilus influenzae , or lymphoproliferative responses were noted during the tacrolimus ointment treatment period. Tacrolimus blood levels were 1 ng/mL or less in all 23 children. Protective pneumococcal titers to all 12 serotypes were observed in 2 of 23 (9%) children prevaccination and in 16 of 23 (70%) children postvaccination. All 6 children who had protective titers to 0 to 5 of the 12 serotypes developed protective titers to an additional 5 to 11 serotypes. Of the patients, 91% had a greater than 4-fold increase in titer for at least 4 of 12 pneumococcal serotypes.CONCLUSION:
Topical application of tacrolimus ointment does not affect the serologic response to pneumococcal vaccine or interfere with preexisting T- and B-cell immune responses.
