Subcategories were formed for recurring keywords, for example, different body localisations. For cross-country comparison, the monthly number of web searches per 100,000 inhabitants was calculated. For detailed methodology, see the Appendix.&lt;/p&gt;&lt;p&gt;Most European countries (&lt;i&gt;n&lt;/i&gt; = 11) had the highest median number of web searches per 100,000 inhabitants for AD-related lay terms, followed by AD (&lt;i&gt;n&lt;/i&gt; = 8) and AE (&lt;i&gt;n&lt;/i&gt; = 2, Figure 1). Analysis revealed common search themes across European countries, including &lt;i&gt;general&lt;/i&gt; disease information, &lt;i&gt;age groups&lt;/i&gt;, &lt;i&gt;localisations&lt;/i&gt;, and &lt;i&gt;treatment&lt;/i&gt;, with slight variations between countries (Figure 2A). The lay term's keywords were often about other diseases. Depending on the search terms, internet queries in some categories focused on different subcategories (Figure 2B). For example, when using the lay term, more countries searched for &lt;i&gt;(natural) remedies&lt;/i&gt; and anogenital localisations, and only AD-related searches included searches for &lt;i&gt;animals&lt;/i&gt;. However, there were also similarities between the search terms, with &lt;i&gt;face&lt;/i&gt;, &lt;i&gt;hands&lt;/i&gt;, and &lt;i&gt;scalp&lt;/i&gt; being the most frequently searched localisations. &lt;i&gt;Age-&lt;/i&gt;related internet searches concerned primarily babies and children, whereas in Austria and Germany, adults were the only search subjects. Search content for lay terms appeared less differentiated than for the other search terms.&lt;/p&gt;&lt;p&gt;Consistent with previous research, both a review study and a global crowdsourced approach found that the term AD was used more freque","PeriodicalId":10334,"journal":{"name":"Clinical and Translational Allergy","volume":"14 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clt2.12355","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140550044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Asthma, AR, and AD collectively affect approximately one-fifth of the global population, imposing a significant economic burden on society. Despite the availability of drugs to treat allergic diseases, they have been shown to be insufficient in controlling relapses and halting disease progression. Therefore, new drug targets are needed to prevent the onset of allergic diseases.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Method&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;We employed a Mendelian randomization approach to identify potential drug targets for the treatment of allergic diseases. Leveraging 1798 genetic instruments for 1537 plasma proteins from the latest reported Genome-Wide Association Studies (GWAS), we analyzed the GWAS summary statistics of Ferreira MA et al. (nCase = 180,129, nControl = 180,709) using the Mendelian randomization method. Furthermore, we validated our findings in the GWAS data from the FinnGen and UK Biobank cohorts. Subsequently, we conducted sensitivity tests through reverse causal analysis, Bayesian colocalization analysis, and phenotype scanning. Additionally, we performed protein-protein interaction analysis to determine the interaction between causal proteins. Finally, based on the potential protein targets, we conducted molecular docking to identify potential drugs for the treatment of allergic diseases.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;At Bonferroni significance (&lt;i&gt;p&lt;/i&gt; &lt; 3.25 × 10&lt;sup&gt;−5&lt;/sup&gt;), the Mendelian randomization analysis revealed 11 significantly associated protein-allergic disease pairs. Among these, the increased levels of TNFAIP3, ERBB3, TLR1, and IL1RL2 proteins were associated with a reduced risk of allergic diseases, with corresponding odds ratios of 0.82 (0.76–0.88), 0.74 (0.66–0.82), 0.49 (0.45–0.55), and 0.81 (0.75–0.87), respectively. Conversely, increased levels of IL6R, IL1R1, ITPKA, IL1RL1, KYNU, LAYN, and LRP11 proteins were linked to an elevated risk of allergic diseases, with corresponding odds ratios of 1.04 (1.03–1.05), 1.25 (1.18–1.34), 1.48 (1.25–1.75), 1.14 (1.11–1.18), 1.09 (1.05–1.12), 1.96 (1.56–2.47), and 1.05 (1.03–1.07), respectively. Bayesian colocalization analysis suggested that LAYN (coloc.abf-PPH4 = 0.819) and TNFAIP3 (coloc.abf-PPH4 = 0.930) share the same variant associated with allergic diseases.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Conclusions&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Our s","PeriodicalId":10334,"journal":{"name":"Clinical and Translational Allergy","volume":"14 4","pages":""},"PeriodicalIF":4.4,"publicationDate":"2024-04-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/clt2.12350","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140348563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
