These episodes were associated with at least two different serotypes of enterovirus. There were no residual neurological deficits and he underwent complete recovery in between. Immunology workup showed normal circulating leucocyte differential counts and lymphocyte subsets. His serum IgG concentration was persistently low but could mount satisfactory specific antibody responses to booster vaccines. The clinical picture was compatible with transient hypogammaglobulinaemia of infancy (THI) which was traditionally believed not to be associated with serious viral infections. This is the first case report to alert physicians that repeated serious enterovirus infections can happen in a relatively benign immunodeficiency disease.<\/jats:p>","DOI":"10.1136\/bcr.12.2008.1358","type":"journal-article","created":{"date-parts":[[2009,6,4]],"date-time":"2009-06-04T04:12:33Z","timestamp":1244088753000},"page":"bcr1220081358","source":"Crossref","is-referenced-by-count":3,"title":["Recurrent enterovirus encephalitis: chance or something else?"],"prefix":"10.1136","volume":"2009","author":[{"given":"Frankie Wai Tsoi","family":"Cheng","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul K S","family":"Chan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wendy C S","family":"Ho","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Felix Y W","family":"Wong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T F","family":"Leung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2009,6,3]]},"reference":[{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.1","doi-asserted-by":"publisher","DOI":"10.1177\/039463200802100211"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.2","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2296-5-23"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.3","doi-asserted-by":"publisher","DOI":"10.1128\/JCM.00542-06"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.4","first-page":"686","article-title":"A case of IgG subclass deficiency with the initial presentation of transient hypogammaimmuno-globulinemia of infancy and a review of IgG subclass deficiencies","volume":"86","author":"Nettagul","year":"2003","journal-title":"J Med Assoc Thai"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.5","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1007\/978-0-387-72005-0_2","article-title":"The four most common pediatric immunodeficiencies","volume":"601","author":"Stiehm","year":"2007","journal-title":"Adv Exp Med Biol"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0091-6749(95)70138-9"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.7","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(78)80417-X"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.8","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(97)09514-7"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.9","doi-asserted-by":"publisher","DOI":"10.1007\/BF00918150"},{"key":"2025042508003394000_2009.jun03_1.bcr1220081358.10","first-page":"141","article-title":"Transient hypogammaglobulinemia of infancy presenting as Staphylococcus aureus sepsis with deep neck infection","volume":"38","author":"Hsueh","year":"2005","journal-title":"J Microbiol Immunol Infect"}],"container-title":["BMJ Case Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/syndication.highwire.org\/content\/doi\/10.1136\/bcr.12.2008.1358","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,25]],"date-time":"2025-04-25T15:00:37Z","timestamp":1745593237000},"score":1,"resource":{"primary":{"URL":"https:\/\/casereports.bmj.com\/lookup\/doi\/10.1136\/bcr.12.2008.1358"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":10,"alternative-id":["10.1136\/bcr.12.2008.1358"],"URL":"https:\/\/doi.org\/10.1136\/bcr.12.2008.1358","relation":{},"ISSN":["1757-790X"],"issn-type":[{"value":"1757-790X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
