Abstract:
Objective Allergic rhinitis (AR) is studied extensively while nonallergic rhinitis (NAR) insufficiently in the recent years .The aim of this study is to describe the inflammation characteristics of different types of NAR . Methods Using the skin prick test , we investigated the characteristics , nasal cytokine levels , serum cytokine levels , and the proportion of peripheral blood Treg cells in 12 cases of AR, 10 cases of NAR with eosinophilia (EOS) syndrome (NARES), 12 cases of NAR without ES (NAR), and 11 control adults . Results The NARES patients had a signifi-cantly higher level of IFN-γ(28.89 [10.97-127.07] pg/mL) than the control (8.98 [7.88-14.90] pg/mL) and the NAR patients (7.92 [7.67-45.85] pg/mL) ( P<0.05) but a lower level of nasal IL-10 than the control ([3.97±0.68] vs [4.80±1.32] pg/mL, P<0.05) .The contents of nasal IL-4, serum IL-4, nasal IL-17 and ser-um IL-17 were all markedly higher in the AR and NARES groups than in the control (P<0.05).The proportion of CD4+CD25+FOXP3+Treg cells in the CD4+T cells in the peripheral blood was (4.5±1.3)%in the AR group and (4.0±1.8) %in the NARES group, both significantly lower than (6.5±1.0) %in the control group (P<0.05) and (6.5±1.0) %in the NAR group (P<0.05). Conclusion NAR was classified according to the EOS level into NARES and NAR without EOS, which had different mechanisms and manifestations of inflammation and similar inflammatory manifestations of Th 2 and Th17.The classification of rhinitis by the level of EOS has more practical significance .
