, cat dander and dog dander were developed for skin prick test (SPT). Since standardization and composition alone cannot guarantee that the allergen extracts are within the concentration range that give the best chance of a true diagnosis, it is necessary to explore the optimal diagnostic concentration (ODC) of allergens in SPT.

To identify the optimal diagnostic concentration of eight allergen extracts in SPT and assess the safety of simultaneous administration.

Patients with a history of allergic disease were enrolled in this two-part open-label, parallel study. In Study 1, 92 patients were enrolled into eight groups according to their disease-causing allergens and were given three increasing concentrations of the corresponding allergen. In Study 2, 20 patients were divided into two concentration groups and were given all of the eight allergens. Safety and sensitivity were evaluated to determine the optimal diagnostic concentration.

In Study 1, the sensitivity of seven allergen extracts was >80% at middle and high concentrations, except for
pollen. The optimal diagnostic concentration (in DU/mL) for eight allergens was 33,333, 12,000, 8667, 50,000, 40,000, 3333, 7000, and 5000. In Study 2, the prevalence of adverse events in the two groups was 70% and 80%, respectively. A total of 10 wheals of 8 patients did not subside <24 h after SPTs.

The eight allergens showed high sensitivity and safety at a certain concentration, which was defined as optimal diagnostic concentration. The results support further clinical research of investigated allergens and our study offers a scheme to determine the ODC of allergens in SPT.

When activated, MCs release pre-formed granules of many pro-inflammatory mediators, including histamine, serotonin, and various chemokines and cytokines including tumor necrosis factor (TNF)-α, interferon ɣ (IFN ɣ), macrophage inhibitory factor, transforming growth factor, interleukin (IL) 1, 3-6, 9, 10, 13 and 16. These mediators promote inflammation in AERD by recruiting or activating a network of cells involved in acute and chronic inflammatory pathways, such as endothelial, epithelial, stromal, and other immune cells. Several studies have implicated multifactorial pathways for MC activation in AERD beyond classical IgE mediated mechanisms. learn more The elucidation of these complex networks therefore represents important targets for innovative patient therapeutics. This review summarizes classic and alternative pathways of MC activation in AERD with a special focus in relation to new and emerging treatment strategies.
The efficacy of antifungal therapy in fungal-associated severe asthma remains controversial.

We aimed to evaluate the differences in the clinical presentation and response to antifungal therapy between severe asthmatics with fungal sensitization and positive fungal isolates.

This retrospective study included 73 patients with severe asthma from January 2004 to December 2017. We examined the presentation, medication, exacerbations, pulmonary function, serum IgE, blood eosinophils, and sputum culture results. Follow-up care was provided to each patient for minimum 3 years.

We classified the patients into four groups group 1, neither fungal sensitization nor fungal isolates in the sputum (n=16); group 2, positive fungal sensitization (n=16); group 3, positive fungal isolates (n=31); and group 4, concomitant positive fungal sensitization and positive fungal isolates (n=10). There were four participants in group 2, 15 in group 3, and 6 in group 4 had received itraconazole therapy for 3 months. Patients in group 3 presented with lower serum IgE level than those in groups 2 and 4. Antifungal therapy significantly improved ACT score during the first year in groups 3 (from 18 [15-22] to 24 [23-24], p=0.0004) and resulted in a long-lasting ACT improvement till the third year in group 3 (from 18 [15-22] to 24 [22-24], p=0.0013).

Antifungal therapy could effectively control the symptoms in patients with severe asthma with positive fungal isolates, contrary to those with merely fungal sensitization; therefore, highlighting the need for a more precise treatment strategy in future for fungal-associated severe asthma.

In contrast, there is a decrease in the prevalence of helminthic infections and other neglected diseases. The hygiene hypothesis elaborates parasitic infection, and allergy-associated diseases have an inverse relationship. Acute helminthic infection and allergic reaction stimulate Type 2 helper cells (Th2) immune response with up-regulation of cytokines IL-4-, IL-5-, and IL-13-mediated IgE and mast cell production, as well as eosinophilia. However, people who chronically suffer from helminthic infections are demarcated through polarized Th2 resulting in alternative macrophage activation and T regulatory response. This regulatory system reduces allergy incidence in individuals that are chronically diseased through helminth. As a result, the excretory-secretory (ES) substance derived from parasites and extracellular vesicular components can be used as a novel therapeutic modality of allergy. Therefore, the aim of this review meticulously explored the link between helminth infection and allergy, and utilization of the helminth secretome for therapeutic immunomodulation.
