Search for: [Abstract = "3\-fold increased risk of PNon\-ANN \(respectively\: OR=3.081\; p=0.038 and OR=2.909\; p=0.024\) comparing to the PAR. There was a significant upward trend in the incidence of PNon\-AR with increasing estimated exposure to tobacco smoke \(p=0.004\). Other factors \(contacts with animals, housing dampness, mold presence, type of flooring, windows construction\) failed to modify the relative proportions of Non\-AR and AR. In all children with PAR and 90% PNon\-AR was found eosinophilic rhinitis \(in the presence of ≥ 10% eosinophils in the nasal cytology examination\). The percentage of eosinophils, neutrophils, the relative proportions of these cells were similar in PAR and PNon\-AR and does not differentiate between these inflammation’s processes. Similarly, spirometry parameters and the frequency and degree of BHR in AR and Non\-AR were similar. BHR was observed in 12% children with PNon\-AR and in 28% ones with PAR \(difference in frequency at the borderline significance, p=0.077\). In children with intermittent non\-allergic rhinitis \(INon\-AR\) the average value of FEV1 was significantly lower compared to the intermittent allergic rhinitis \(IAR\) \(p=0.014\). Moreover, BHR was present in 5 out of 17 children \(29%\) with INon\-AR and in 2 of 12 \(18%\) with IAR \(p=0.49\). The values %FEV1 in the two groups did not differ significantly. Among the analyzed markers of allergic inflammation, only the value"]
