There were no statistical differences between these 2 groups of children with regard to age, sex, serum IgE levels or prevalence of asthma. However, the prevalence of eczema was significantly lower in the infection-prone group (p = 0.035). Of greater interest was the finding that 7 children in the infection-prone group had IgG subclass and\/or IgA deficiency compared with none in the non-infection-prone group (p = 0.006). These results suggest that IgG subclass studies may be warranted in children with markedly elevated levels of serum IgE and proneness to infection.<\/jats:p>","DOI":"10.1159\/000235255","type":"journal-article","created":{"date-parts":[[2009,8,7]],"date-time":"2009-08-07T09:46:18Z","timestamp":1249638378000},"page":"285-288","source":"Crossref","is-referenced-by-count":6,"title":["Immunoglobulin G Subclass Deficiency in Children with High Levels of Immunoglobulin E and Infection Proneness"],"prefix":"10.1159","author":[{"given":"R.K.S.","family":"Loh","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Y.H.","family":"Thong","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Ferrante","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,8,7]]},"container-title":["International Archives of Allergy and Applied Immunology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/235255","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000235255","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T11:07:02Z","timestamp":1777633622000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000235255"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,8,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000235255","archive":["Portico"],"relation":{},"ISSN":["0020-5915","2571-6662"],"issn-type":[{"value":"0020-5915","type":"print"},{"value":"2571-6662","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,8,7]]}}}
