About Allergology International

Allergology International is the official journal of the Japanese Society of Allergology and publishes original papers dealing with the etiology, diagnosis and treatment of allergic and related diseases. Papers may include the study of methods of controlling allergic reactions, human and animal models of hypersensitivity and other aspects of basic and applied clinical allergy in its broadest sense.

The Journal aims to encourage the international exchange of results and encourages authors from all countries to submit papers in the following three categories: Original Articles, Review Articles, and Letters to the Editor.

The acceptance criteria for all papers are the quality and originality of the research and its significance to our readership. Except where otherwise stated, manuscripts are peer reviewed by two anonymous reviewers and the Editor.

Editor's Choices

Original Article

Editor’s comment: Long COVID causes multiple prolonged symptoms, including general fatigue, in patients recovered from COVID-19 infections. Sunata et al. conducted a multicenter cohort study at 26 medical institutions to identify the risk factors for general fatigue in long COVID. They found that asthma, younger age, and female sex were risk factors for prolonged fatigue by univariate logistic regression analysis and that asthma was an independent risk factor for persistent fatigue during the 12-month follow-up period by multivariable logistic regression analysis. They conclude that patients with asthma need to take strong preventive measures against COVID-19 to avoid sustained fatigue, thereby minimizing their social and economic losses.

Original Article

Editor’s comment: Asthma has been classified into several phenotypes based on various factors, including age. Chuang et al. conducted a factor analysis to select 17 variables and classified subjects with asthma phenotypes using a two-step cluster analysis. They identified three clusters with different characteristics in nonelderly and elderly asthmatic adults, finding that asthma in elderly patients has different phenotypes than asthma in nonelderly patients. Their age-stratified cluster study also demonstrated heterogeneous clinical characteristics, occupational factors, and inflammatory patterns between nonelderly and elderly asthma adults. These findings suggest that classifying asthma phenotypes stratified by age may lead to more precise patient identification, bringing us closer to personalized disease management.

Original Article

Editor’s comment: Atopic dermatitis and autoimmune diseases, both beginning at an early age, are immune-mediated diseases involving genetic predisposition. Although there have been several studies on the co-occurrence of atopic dermatitis and autoimmune diseases, the association between the two diseases is still controversial. Ahn et al. address this point using a national administrative cohort study involving 499,428 children born in Korea. They found that during a mean follow-up of 12 years, the group exposed to atopic dermatitis had an increased risk of autoimmune disease (hazard ratio, 1.27 [95 % confidence interval, 1.23-1.32]) compared to the unexposed group and that the hazard ratios of autoimmune illnesses consistently increased with two- and five-year lag times.

Review Series: Non-IgE-mediated food allergy: Where are we now?

Invited Review Article

Prof. Nowak-Wegrzyn and her colleagues focused on the current and future perspectives of the international consensus guideline for non-IgE-mediated food allergies. The establishment of the 2017 guidelines greatly aided in recognizing this difficult-to-diagnose disease, particularly in childhood. The guidelines provided a common language for clinicians and researchers worldwide. She summarizes current clinical questions and comments related to this topic, in particular oral food challenge testing and the treatment of FPIES. Some of these issues may be incorporated into the revised version of the international consensus guidelines, which is forthcoming.

Invited Review Article

Prof. Morita and his colleagues primarily focus on the heterogeneity of non-IgE-mediated food allergies and propose pathogenetic mechanisms to explain this heterogeneity. In addition, their review article aims to separate "early-onset neonatal FPIES," characterized by severe vomiting with macroscopic bloody stool, from acute and chronic FPIES, in line with their previous studies. Finally, they demonstrate geographic heterogeneity of triggering foods for acute FPIES.
