Objective To evaluate the significance of several Dermatophagoides pteronyssinus allergen extracts for skin prick test(SPT) in patients allergic to Dermatophagoides pteronyssinus.Methods Two hundred and nineteen patients enrolled in Peking Union Medical College Hospital underwent SPT and serum specific IgE assay to detect the Dermatophagoides pteronyssinus allergen.Three kinds of house dust mite allergen extracts were used for SPT,including the Dermatophagoides pteronyssinus extract prepared by our laboratory(group A),standardized Dermatophagoides pteronyssinus extract(group B),and mixed extracts of Dermatophagoides pteronyssinus and Dermatophagoides farinae(group C).Human serum specific IgE result was regarded as the reference standard for diagnosis of Dermatophagoides pteronyssinus allergy.The receiver operating characteristic(ROC) curve was used to evaluate the diagnostic performance of SPT with the extracts of three groups.Results SPT results showed that the median wheal diameter of group A,group B,and group C was 0.43,0.35,and 0.28 cm,respectively,with significant difference among three groups(P<0.05).The difference was significant between group A and B(P<0.01) as well as group A and C(P<0.01),but not between group B and C(P>0.05).There was no local urticaria or systemic allergic reactions following the procedure of SPT.Local reaction was observed in 5 patients and delayed reaction was in 2 patients of group A.As for group B and C,local reaction occurred in 3 cases and delayed reaction in 2 cases in each group.The area under ROC curve of SPT with extract in group A,group B,and group C was 0.765,0.801,and 0.782,respectively.Based on the detection results of serum specific IgE,the sensitivity of SPT in diagnosis of Dermato-phagoides pteronyssinus allergy with extract of group A,group B,and group C was 92.4%,87.0%,and 81.5%,and the specificity was 60.6%,73.2%,and 74.8%,respectively.Conclusion The Dermatophagoides pteronyssinus extract for SPT prepared by our laboratory offers good sensitivity and specificity comparable to commercially available allergen extracts,and it may be an appropriate candidate for clinical screening and diagnosis of Dermatophagoides pteronyssinus allergy. 展开更多

The high-order implicit finite difference schemes for solving the fractional- order Stokes' first problem for a heated generalized second grade fluid with the Dirichlet boundary condition and the initial condition are given. The stability, solvability, and convergence of the numerical scheme are discussed via the Fourier analysis and the matrix analysis methods. An improved implicit scheme is also obtained. Finally, two numerical examples are given to demonstrate the effectiveness of the mentioned schemes 展开更多

Background: Wheat-dependent, exercise-induced anaphylaxis (WDEIA) is an allergic reaction induced by intense exercise combined with wheat ingestion. The gold standard for diagnosis of WDEIA is a food exercise challenge: however, this test is unacceptable for Chinese WDEIA patients and unable to be approved by the Ethics Committee of Chinese hospitals due to substantial risk. There are no diagnostic criteria tbr Chinese WDEIA patients. The aim of present study was to propose new practical diagnosis criteria t'or Chinese WDE1A patients. Methods: We prospectively included 283 clinically diagnosed WDEIA patients from January 1,2010 to June 30, 2014, and in tile meanwhile, three groups were enrolled which included 133 patients with the history of anaphylaxis induced by lbod other than wheat. 186 recurrent urticaria patients, and 94 healthy participants. Clinical comprehensive evaluation by allergists used as the reference gold standard, receiver operator characteristic (ROC) curves were plotted, areas under curve (AUC) tbr specific immunoglobin E (slgE) were compared to evaluate the diagnostic value of lgE specific to wheat, gluten, and 0)-5 gliadin. Patients were followed up by telephone questionnaire 1 year after diagnosis. Results: We reviewed 567 anaphylactic reactions in 283 WDEIA patients. Of these anaphylactic reactions, 415 (73.3%) reactions were potentially life-threatening anaphylaxis. Among the 567 anaphylactic reactions, 75% (425/567) occurred during exercise. The highest AUC (0.910) was observed for sIgE for gluten, followed by omega-5 gliadin (AUC 0.879). Combined gluten- and co-5 gliadin-specific IgE testing provided sensitivity and specificity of 73.1% and 99.0%, respectively. During the 1-year follow-up period, repeat anaphylaxis was rare when patients observed strict avoidance of wheat products combined with exercise or other triggering agents. Conclusions: In this study, we proposed diagnostic criteria and management of WDEIA patients in China, Our present study suggested that confirmed anaphylactic reactions triggered by wheat with positive slgE to gluten and omega-5-gliadin may provide supportive evidence for clinicians to make WDEIA diagnosis without perforating a food exercise challenge. 展开更多

Allergic contact dermatitis is a common clinical allergic disease.The patch test is the gold standard for finding and clarifying contact allergens.With the deepening understanding of the epidemiology,pathogenesis,and clinical manifestations of contact dermatitis,as well as the increased requirements for the standardized application of patch tests,the relevant consensus needs to be continuously updated.This consensus is updated on the basis of the version issued in 2015.In this revised version,it refines the selection of clinical indications,improves the judgment end interpretation of results,adds delayed detection and patient education,and so on,which aims to further standardize clinical applications and improve the value of patch test. 展开更多
