目的探讨真菌变应原在慢性鼻-鼻窦炎发病中的作用。方法实验组为慢性鼻-鼻窦炎患者30例,对照组为同期鼻中隔偏曲患者30例,检测患者血清TIgE、血清SIgE、嗜酸粒细胞阳离子蛋白(ECP)及吸入物过筛试验。结果实验组血清TIgE、SIgE、ECP均高于对照组,有统计学差异。结论在慢性鼻-鼻窦炎中嗜酸粒细胞处于活化状态,嗜酸粒细胞活化促进了病变的迁延与发展;慢性鼻-鼻窦炎变应原以户尘螨、粉尘螨、北艾、蓓草为主,真菌变应原检出较少。  相似文献

目的研究粉尘螨和屋尘螨之间是否存在交叉反应。方法应用Uni CAP System对480例粉尘螨皮肤点刺试验阳性的过敏性鼻炎患者血清进行屋尘螨、粉尘螨SIgE检测。结果粉尘螨SIgE等于或大于2级的患者,100%同时屋尘螨SIgE等于1级或以上,且大部分阳性等级相当。粉尘螨SIgE 1级患者,有90%患者屋尘螨SIgE等于1级或以上,只有10%患者屋尘螨SIgE 0级,但其荧光值较高,均接近1级的荧光值水平。把其中100例屋尘螨和粉尘螨同时过敏的患者血清进行热带无爪螨变应原检测,只有26%的阳性率,且阳性级别均在3级以下。应用粉尘满舌下含服制剂对102例患者进行免疫治疗2年,症状完全缓解有45例,44.12%,其中有效86.27%,显效83.91%,良效2.36%,微效13.73%。结论绝大部分对粉尘螨变应原过敏的患者同时对屋尘螨变应原过敏,粉尘螨和屋尘螨变应原存在高度的交叉反应,用粉尘螨变应原免疫制剂治疗可达到较好的疗效,而粉尘螨和屋尘螨变应原与热带无爪螨变应原关系不密切。  相似文献

Objectives: To investigate the occupational exposure and sensitization to storage mites (SM) in sales staff working in a moisture-damaged and three healthy reference buildings. Methods: The study population consisted of the entire personnel (n=12) in the moisture-damaged grocery store. They all suffered from persistent upper respiratory tract symptoms. Twelve (in results 11) symptom-free controls working in three healthy reference groceries were matched with age, sex and occupation. Dust samples from each building were examined for mites. The clinical study consisted of otorhinolaryngological examination and determination of IgE reactivity. Specific serum IgE antibodies were measured against three SMs and two house dust mites (HDM). Skin prick tests (SPT) were made to the same five mites and to five common aeroallergens. If sensitization to any of the SMs was detected, a nasal provocation test (NPT) was performed. Results: SMs were found in all buildings. In all, seven cases and four control subjects showed IgE-mediated reactivity. Sensitization to mites was detected in six cases and in three controls and in 2/12 and 3/11 this was the only IgE antibody response observed. In addition, one case and one control subject were sensitized to common aeroallergens. NPT with SMs was positive in four cases and in one control. Conclusions: In grocery stores, the personnel are exposed to SMs. The risk of sensitization to mites is obvious and an IgE response can occur without any reactivity to common aeroallergens. SM allergy may in some cases explain the chronic rhinitis related to moisture-damaged buildings.  相似文献

Kawasaki syndrome: a controlled study of an outbreak in Wisconsin   总被引:2,自引:0,他引:2  
The etiology of Kawasaki syndrome remains unestablished, although a possible role has been suggested for exposure to the application of carpet shampoo, house dust mites, and rickettsial infection. During an outbreak of 20 cases of Kawasaki syndrome that occurred in southeastern Wisconsin from November 1982 through March 1983, a case-control study was done of 15 cases and 30 matched controls. The study included questionnaire administration, dust collection from homes, and serum specimen collection. Only one patient had been exposed to a shampooed carpet within 30 days before onset of illness. No differences were noted between cases and controls in the degree of exposure to house dust mite-associated factors in the home, nor in the occurrence, density and species-specific prevalence of house dust mites in the home. Meadow voles exposed to house dust mites from the homes of patients did not develop serologic or pathologic evidence of infection due to rickettsiae in the spotted fever and typhus groups or Coxiella burnetii. Anti-mite-specific immunoglobulin E was not detected in serum specimens from cases or controls. Results from this study do not support hypotheses suggesting that the development of Kawasaki syndrome is associated with exposure to application of carpet shampoo, house dust mites, or rickettsial infection.  相似文献

It has been hypothesised that house dust mite is as a causative and/or deteriorating factor in some cases of chronic urticaria. In this report we describe two patients with the history of respiratory house dust mite allergy and chronic urticaria, which resolved in the course of house dust mite immunotherapy. Basing on literature and our own experiences, we can only speculate that some patients suffering from mite-induced respiratory allergy and concomitant chronic urticaria may benefit additionally from allergen immunotherapy, manifesting as the withdrawal or alleviation of urticaria symptoms.  相似文献

House dust mites have been shown to be important sources of indoor allergens associated with asthma and other allergic conditions. Asthma is a chronic respiratory disease that affects millions of people worldwide, and numerous scientific studies have shown that the prevalence of asthma is increasing. The most common dust mite species around the world include Dermatophagoides pteronyssinus (Dp), Dermatophagoides farinae (Df), Euroglyphus maynei (Em) and Blomia tropicalis (Bt). Over the past three decades, many important allergens from these species have been identified and characterized at the molecular level. The biological function of several house dust mite allergens has been elucidated, with many of them showing enzymatic activity. However, Bt allergens remain the least studied, even though this mite is very common in tropical and subtropical regions of the world, including Puerto Rico. Therefore, it is very important to include Bt in diagnostic and therapeutic strategies for house dust mite induced allergy and asthma, particularly in areas where Bt exposure and sensitization is high. Recombinant DNA technology, as well as other molecular biology and immunological techniques, have played a fundamental role in advances towards a better understanding of the biology of house dust mites and their role in allergic diseases. This kind of study also contributes to the understanding of the complex immunologic mechanisms involved in allergic reactions. The development of effective diagnostic and therapeutic approaches depends on the continuity of research of house dust mite allergens. The objectives of this review are to describe the most important aspects of house dust mite allergy and to acquaint the scientific community with the latest findings pertaining to house dust mite allergens, particularly those derived from Bt.  相似文献

A statistical analysis was made of data concerning diagnosis of IgE-mediated allergy in the upper respiratory tract in 292 patients. It appears that screening for an IgE-mediated allergy can be performed with a limited number of skin tests (rye grass, timothy, birch, house dust mite and cat). In this study a larger number of skin tests (15 instead of 5) and investigation of specific IgE (RAST) yielded little additional information (in 2% and 3% of the patients, respectively). When indicated, an extended series of skin tests, immuno-assay (total IgE and specific IgE) and eosinophil counts in the serum and nasal smear should be performed.  相似文献
