Abstract
BACKGROUND
Allergic rinitis is the more common allergic disease, affecting to 25% of general population. Otitis media, sinusitis and other complications result from not controlled allergic rinitis. It has been reported that a low expression of FOXP3 marker on lymphocytes is associated with allergic diseases, and that allergen immunotherapy increases its synthesis.
OBJECTIVE
To compare CD4+ FOXP3+ T cell levels in patients with allergic rhinitis, with and without allergen immunotherapy.
METHODS
In this cross-sectional, observational and comparative study were included adult patients with allergic rinitis in two groups: one group with 29 patients under allergen immunotherapy for six months, and other group with 30 patients without immunotherapy. Lymphocyte markers CD3, CD4, CD8 y FOXP3 were determined in both groups, as well as serum immunoglobulins.
RESULTS
In the group treated with immunotherapy the mean age was 36.4 years, and 72% of them were women. In the other group the age average was 40.4 years and 63% were women. There were no significant differences in immunoglobulin levels among both groups; IgG4 had higher levels, but not significant, in the immunotherapy group (82.1 vs 72.4 mg/dL, p=0.67). Patients from the group without immunotherapy had higher number of FOXP3+ lymphocytes, but not significant (8.2 vs 7.9, p=0.57).
CONCLUSIONS
Patients treated with allergen immunotherapy had lower FOXP3+ lymphocytes number than those not treated. More studies are needed for considering FOXP3+ lymphocyte molecule as a useful marker in the follow-up of patients under immunotherapy.
