原標(biāo)題：塵螨致敏患者過敏原組份診斷
　?、俦尘埃悍肿舆^敏診斷的應(yīng)用可以提高特異性過敏原免疫治療的療效②方法：在2018年的5個(gè)月內(nèi)，以437例年齡在34.6±5.4 歲的患者（其中56.1% 男性，43.9% 女性）為對(duì)象，使用Raptor Analysis MADx (kUA/L)對(duì)屋塵螨敏感的患者進(jìn)行allergochip ALEX主要過敏原組份評(píng)估。③結(jié)果：106例(24.3%)對(duì)屋塵螨敏感。89例(83.9%)血清總IgE升高(294±4.3)。屋塵螨主要成分陽性情況如下:Der p 2  88例(83.1%)；Der p 1  48例 (45.3%);Der p 23  48例(45.3%)；Der p 5  25 例(23.6%)；Der p 7  18例 (17.0%)；和Der p11  9 例(8.5%)；粉塵螨的主要成分:Der f 1  67 例(63.2%)， Der f 2  65 例(61.3%);原肌球蛋白Der p10  9例(8.5%)。以主要過敏原Der p2和Der f1為主，范圍從0.12 kU/l到38.2 kU/l，但只有4例(3.8%)只對(duì)Der p 5敏感；3例(2.8%)只對(duì)Der p23敏感；1例(0.9%)只對(duì)Der p11敏感；而9例(8.5%)對(duì)主要過敏原 Der p 5, 7, 11均敏感的病人，他們對(duì)這三種組份的特異性IgE水平比對(duì)Der p 2 和/或Der p 1的特異性IgE水平更高（p<0.05）。④結(jié)論：對(duì)室內(nèi)塵螨敏感的患者可能對(duì)Der p1、Der p2同時(shí)敏感，對(duì)Der p5、7、11和23的特異性IgE的存在，提示應(yīng)優(yōu)化AIT制劑，使之含有多種過敏原組分。

Allergen Component Diagnosis of Patients with House Dust Mite Sensitization
DOI: https://doi.org/10.1016/j.jaci.2018.12.718
Rationale
The use of molecular allergy diagnostics may enhance specific allergen immunotherapy (AIT).
Methods
437 patients aged 34.6±5.4 years, 56.1% males 43.9% females, were assessed over five months in 2018. The allergochip ALEX allowing major allergen component assessment was performed on patients sensitized to house dust mites, using Raptor Analysis MADx, (kUA/L).
Results  
106 (24.3%) were dust mite sensitized. Total serum IgE was elevated (294±4.3) in 89 (83.9%) individuals. Major components of D. Pteronyssinus seen were: Der p 2 – in 88 (83.1%); Der p 1 -in 48 (45.3%); Der p 23 – in 48 (45.3%); Der p 5 – in 25 (23.6%); Der p 7 – in 18 (17.0%); and Der p 11 – in 9 (8.5%) ; major components of D. Farinae: Der f 1 – in 67 (63.2%), Der f 2 – in 65 (61.3%); and tropomyosin Der p 10 in 9 (8.5%) of patients. Major components of Der p 2 and Der f 1 dominated, ranging from 0.12 kU/l to 38.2 kU/l, but 4 (3.8%) were sensitized only to Der p 5; 3 (2.8%) to Der p 23; 1 (0.9%) to Der p 11; and 9 (8.5%) co-sensitized to major components Der p 5, 7, 11 at higher levels (p<0.05) of sIgE, than to Der p 2 and/or Der p 1.
Conclusions
Patients with sensitization to house dust mites may have combinations of sensitization to Der p 1 and Der p 2 and sIgE to Der p 5, 7, 11 and 23 suggesting optimization of AIT may require presence of multiple allergen components.
