For the first time, these included a stepwise plan for the reintroduction of egg for egg-allergic children who could already tolerate well-cooked egg, such as cakes and cookies. Since then, various egg ladders have been developed [2, 3, 4, 5, 6, 7, 8, 9]. In the past 3 years, several studies have been published suggesting that a gradual introduction of highly processed to less processed egg containing foods contribute to the acceleration of tolerance development [2, 3, 4, 5]. However, depending on the study and egg ladder, the egg products vary in their level of processing (wheat matrix, degree, and location of heating (e.g., oven, pan, pot), egg quantity, and egg protein). In the UK, the introduction of the egg ladder is recommended at the age of 12 months or if the last reaction occurred 6 months before. The benefits of introducing egg at home include an early increase in the variety of foods, reduction of food fears, improved nutrient intake, and the avoidance of hospitalization fears in children [10]. Children with mild reactions in the past can start with small amounts of baked goods at home. Food challenges in an inpatient setting to exclude or reconfirm the allergy should be conducted if the patients have previously had severe allergic reactions, i.e., anaphylaxis, or if the smallest amounts triggered an allergic reaction or if existing asthma is poorly controlled [10, 11].

From these, a new egg ladder as therapeutic option for the German-speaking region has been developed.

Physicians face the challenge to find single, extremely rare PAD patients/families among the millions of individuals with common allergic diseases. We describe case scenarios with signature PAD. We review the literature and deduct specific clinical red flags for PAD detection. They include a positive family history and/or signs of pathological susceptibility to infections, immunodysregulation, or syndromic disease. Results of conventional laboratory and most immunological lab studies are not sufficient to make a definitive diagnosis of PAD. In the past, multistep narrowing of differential diagnoses by various immunological and other laboratory tests led to testing of single genes or gene panel analyses, which was a time-consuming and often unsuccessful approach. The implementation of whole-genomic analyses in the routine diagnostics has led to a paradigm shift. Upfront genome-wide analysis by whole genome sequencing (WGS) will shorten the time to diagnosis, save patients from unnecessary investigations, and reduce morbidity and mortality. We propose a rational, clinical landmark-based approach for deciding which cases pass the filter for carrying out early WGS. WGS result interpretation requires a great deal of caution regarding the causal relationship of variants in PAD phenotypes and absence of proof by adequate functional tests. In case of negative WGS results, a re-iteration attitude with re-analyses of the data (using the latest data base annotation)) may eventually lead to PAD diagnosis. PAD, like many other rare genetic diseases, will only be successfully managed, if physicians from different clinical specialties and geneticists interact regularly in multidisciplinary conferences.</p>","PeriodicalId":101298,"journal":{"name":"Allergologie select","volume":"8 ","pages":"304-323"},"PeriodicalIF":0.0,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11460323/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142396601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
