Specific IgE to Total IgE Ratio Does Not Improve Peanut Diagnostic Accuracy in Adults
Conclusions: We found that there was no significant benefit in using peanut sIgE to tIgE ratio over sIgE alone to predict peanut reactivity in an adult population. Larger prospective studies are needed to further confirm these findings.Int Arch Allergy Immunol (Source: International Archives of Allergy and Immunology)

miR-146a-5p Attenuates Allergic Airway Inflammation by Inhibiting the NLRP3 Inflammasome Activation in Macrophages
Conclusion: miR-146a-5p inhibited NLRP3 inflammasome activation in macrophages in the lung tissue of allergic mice, prevented pro-inflammatory phenotype M1 polarization, and promoted anti-inflammatory phenotype M2 polarization by targeting the TIRAP/NF- κB pathway, thus alleviating airway inflammation in allergic asthma.Int Arch Allergy Immunol (Source: International Archives of Allergy and Immunology)

The Contribution of Complement Protein C1q in COVID-19 and HIV Infection Comorbid with Preeclampsia: A Review
Dysregulation in component 1q (C1q) levels is associated with weak placental development in preeclampsia (PE). Human immunodeficiency virus infection (HIV-1) triggers the C1q complex, resulting in opsonization of healthy host cells, contributing to their removal, and augmented progression of HIV disease. In coronavirus disease 2019 (COVID-19)-infected patients, the deposition of C1q activates the complement. Considering the paucity of data, this review highlights a significant gap in the potential of C1q in the immunocompromised state of preeclamptic HIV-infected women and COVID-19 infection. In PE, C1q is downregulated; w...

Evaluation of the Clinical Characteristics of Patients with Food Protein-Induced Enterocolitis Syndrome: A Multicenter Study
Conclusion: FPIES is a non-IgE-mediated food hypersensitivity that commonly affects infants and is often misdiagnosed. The pathophysiology of the disease remains unclear and the low awareness of FPIES among physicians and parents highlights the need for more education.Int Arch Allergy Immunol (Source: International Archives of Allergy and Immunology)

TRIM33 Modulates Inflammation and Airway Remodeling of PDGF-BB-Induced Airway Smooth-Muscle Cells by the Wnt/ β-Catenin Pathway
In this study, the TRIM33 expressions in serum samples and platelet-derived growth factor BB (PDGF-BB)-induced airway smooth-muscle cells (ASMCs) were evaluated. A gain-of-function experiment was performed, and cell proliferation and migration were detected using CCK-8 and w ound healing assays. Besides, the protein levels of EMT biomarkers and airway-remodeling markers were determined by Western blot assay. ELISA analyzed the contents of IL-1β, IL-6, and TNF-α in the supernatant. The modulation of Smad4 expression and subsequent activation of Wnt/β-catenin by TRIM33 were also assessed. We found that TRIM33 was downregu...

Delayed Pressure Urticaria: Clinical and Diagnostic Features and Response to Omalizumab
Conclusions: Despite the limitation of a low sample size in this real-life study, our findings suggest that omalizumab is a rapid, effective, and safe treatment for patients with DPU refractory to antihistamines in an up-dosing regimen. We recommend omalizumab for patients who do not respond to up-dosing antihistamines and montelukast.Int Arch Allergy Immunol (Source: International Archives of Allergy and Immunology)

Mast Cell Activation Syndromes: Collegium Internationale Allergologicum Update 2022
Mast cell activation syndromes (MCASs) are defined by systemic severe and recurrent mast cell activation, usually in form of anaphylaxis, a substantial, event-related increase of the serum tryptase level beyond the individual ’s baseline and a response of the symptomatology to drugs directed against mast cells, mast cell-derived mediators, or mediator effects. A number of predisposing genetic conditions, underlying allergic and other hypersensitivity states, and related comorbidities can contribute to the clinical mani festation of MCASs. These conditions include hereditary alpha tryptasemia, mastocytosis with an expansi...

The Identification and Characterization of Immunoreactive Fungal Proteins Recognized by Sera from Zimbabweans Sensitized to Fungi
Conclusions: We identified novel immunogens from fungi expanding the number of known fungal allergens. These form a potential basis for diagnostics specific for the Zimbabwean population. Validation assays will now need to be carried out to further evaluate the cross-reactivity of the identified allergen candidates as well as investigate their potential recognition in a larger cohort of patients. Furthermore, there is now a need to conduct studies relating sensitization to these immunogens and clinical diseases in the population.Int Arch Allergy Immunol (Source: International Archives of Allergy and Immunology)
