The Impact

Local allergic rhinitis is a localized allergic response of the nasal mucosa to aeroallergens in the absence of atopy with characteristic production of specific local immunoglobulin E antibodies in the nasal mucosa, T helper type 2 cellular infiltration response during the exposure to aeroallergens and positive results via the nasal allergic provocation test with the release of inflammatory mediators (triptase and eosinophil cationic proteins). Even though the prevalence of local allergic rhinitis has been and is still being investigated, a large number of patients with diagnosed non-allergic rhinitis or idiopathic rhinitis are currently classified as having local allergic rhinitis. The causes of local allergic rhinitis are most commonly house dust, dust mites, pollens and many others. Diagnosis of local allergic rhinitis is made using nasal allergen provocation tests when the prick test for standard inhalation allergens and the serum specific immunoglobulin analysis for aeroallergens are negative. The increasing amount of data on localized allergic response in non-atopic patients asks for many answers regarding local allergic rhinitis. These answers can be obtained by a study on the prevalence and incidence in children and adults, the impact of positive family atopy in the development of disease, the impact of associated diseases of the lower respiratory tract and conjunctiva, the effectiveness of drug treatment and the issue of administration of specific immunotherapy.

Nasal Provocation Testing

Background Allergen identification is the first step for allergen-specific immunotherapy (AIT) of allergic rhinitis (AR). Currently, the diagnosis of AR is based mainly on the positive results of the skin prick test (SPT) and/or serum specific immunoglobulin E (sIgE) measurement. However, the results of these two tests may not always directly correlate with AR. Objective To investigate the importance of nasal provocation testing (NPT) in the diagnosis of Dermatophagoides pteronyssinus (Der p)-induced AR. Methods Rhinitis patients willing to undergo AIT (n = 171) were enrolled. The correlations of Der p SPT, sIgE, NPT, and clinical symptom severity were assessed. Results NPT-positive responses were more common in patients with higher SPT and sIgE levels. The optimal cut-off value for a NPT-positive response for SPT was 5.5 mm and for sIgE was 2.77 kUA/L, based on the respective receiver operating characteristic (ROC) curves. The area under the curve (AUC) of the ROCs was 0.814 (SPT only) and 0.794 (sIgE only) and increased to 0.828 with the combination of SPT and sIgE. The Der p-NPT concentration was inversely correlated with SPT and sIgE levels ( r = −0.477, P < .001, and r = −0.461, P < .001, respectively), but none was correlated with the total nasal symptom score. Conclusion For patients who are willing to receive Der p AIT, NPT is a useful and safe test to confirm diagnosis prior to treatment initiation, especially in patients with lower levels of Der p SPT (< 5.5 mm) or sIgE (< 2.77 kUA/L).

The Impact

Background. Efficacy of allergen immunotherapy (AIT) in local allergic rhinitis (LAR) is a new subject of research. The presence of asthmatic symptoms in patients with LAR in the context of AIT is unexplored. Objective. The efficacy and safety of AIT in patients with LAR towards birch pollen were investigated. The possibility of concomitant local allergic asthma in studied patients and the impact of AIT on it were examined. Methods. 36 patients with LAR towards birch were included in three years of AIT in a double-blind, placebo-control study. Primary outcome measurement was the mean changes in the combined symptom and medication scores (CSMSs) after AIT, and the second is the changes in the quality of life (QoL). Skin prick tests, serum, nasal allergen-specific IgE to birch, nasal and bronchial provocation challenge tests with birch allergen, methacholine tests, and spirometry were carried out at baseline and after AIT. Results. Mean CSMSs of three years of AIT were significantly decreased in the active group from 5.88 (range: 4.11-9.01) to 1.98 (range: 1.22-4.51; p<0.05). After three years of AIT, there was a significant increase of toleration for birch allergen from the mean concentration of 6250±1200 SQ-U/ml up to 45000±2500 SQ-U/ml (p=0.02) during repeated nasal challenges. 16 patients with LAR had the positive results of methacholine tests, and 11 of them had a positive bronchial challenge to birch allergen. After AIT, the significant decrease of bronchial responsiveness to birch allergen in 5 from 7 patients was confirmed (p=0.03). QoL assessed by the use of the RQLQ score was improved after AIT from 1.84 (95% CI: 1.53-1.97) to 1.45 (95% CI: 1.32-1.62) score in the active group after three years of AIT therapy (p=0.03). Conclusion. AIT to birch can be useful and safe in a patient with local allergic rhinitis and also with concomitant asthmatic symptoms. Further studies are needed.

<b><i>Introduction:</i></b> Different endotypes of rhinitis are known, but its pathomechanism has not been conclusively established. For example, the precise difference between systemic allergic rhinitis (SAR) and local allergic rhinitis (LAR) is still being checked. Comparison of patients with LAR and with allergies to birch of those with intermittent allergic rhinitis, same allergy, or with non-allergic rhinitis (NAR) was the purpose of this study. <b><i>Methods:</i></b> Twenty-six patients with LAR, 18 with SAR and allergy to birch, and 21 with NAR were included. Patients who met the inclusion criteria were selected to undergo the following procedures at baseline: medical examinations, nasal provocation test (NPT), detection of nasal-specific IgE to birch as well as basophil activation test (BAT). All immunological parameters were detected before and after NPT. <b><i>Results:</i></b> Concentration of nasal IgE to Bet v1 increased comparably in the LAR and SAR groups after NPT to birch as follows: in 21 (81%) patients with LAR, 14 (78%) with SAR, and in everyone in the NAR group. Serum concentration of allergen-specific IgE to Bet v1 increased significantly from a median of 20.7 (25–75% interval: 11.2–35.6) IU/mL to 29.9 (13.6–44.1) (<i>p</i> = 0.028) after NPT in patients with SAR. Allergen-specific IgE to Bet v1 was absent in all patients with LAR and NAR before and after NPT. BAT with Bet v1 was positive in 22 (85%) patients with LAR, in 14 (78%) with SAR, and 2 (9.5%) with NAR. <b><i>Conclusion:</i></b> These obtained data suggest there are no potential mechanisms that could explain LAR compared to SAR.

Predator Mite

Mites can sensitize and induce atopic disease in predisposed individuals and are an important deteriorating factor in patients with allergic rhinitis, asthma, and atopic dermatitis. Although Pyroglyphidae mites have been extensively studied, very scarce reports are available on Cheyletidae spp. especially regarding human respiratory pathology. The main objective of the present study is to investigate the clinical role of this predator mite (Cheyletus eruditus) as a respiratory antigen in a selected sensitized human population. Fifty-two adult patients were recruited from the outpatient allergy clinic to assess their eligibility for the study. The thirty-seven subjects with persistent allergic rhinitis (PAR) who fulfilled the ARIA criteria had a positive IgE response confirmed by skin prick test (SPT) toC. eruditus. Only those individuals (37/47) with a positive SPT toC. eruditusshowed a positive nasal provocation test (NPT), while 10 patients with nonallergic mild-to-moderate persistent rhinitis,control group, had a negative NPT withC. eruditus. The present paper describes a new role for the predator miteCheyletus eruditusas a respiratory allergen in a selected subset of patients in a subtropical environment afflicted with persistent nonoccupational allergic rhinitis.

Background. Chitinase-like protein YKL-40 plays an important role in human atopic diseases. The aim of this study was to determine of the level of chitinase-like protein YKL-40 in the secretions of nasal mucosa of patients with chronic allergic rhinitis. Methods. Samples of allergic nasal mucosa were obtained from twelve patients with perennial allergic rhinitis. Measurement of nasal YKL-40 levels was performed with modification in duplicate using commercially available ELISA kits for YKL-40. The amount of nasal eosinophils and neutrophils were also determined. Results. There were significant differences between healthy volunteers and patients with allergic rhinitis for mucosal YKL-40 levels and the amount of nasal eosinophil and neutrophil cells, which have some characteristics closely associated with allergic response. The nasal YKL-40 levels in patients with allergic rhinitis were in tens times more higher than those in controls. Conclusion. Thus, we conclude that the level of chitinase-like protein YKL-40 was upregulated in allergic nasal mucosa compared with normal nasal mucosa, suggesting their roles in the pathogenesis of allergic rhinitis.
