In most developing Middle Eastern countries, chILD is still underdiagnosed. Our objective was to describe and investigate patients diagnosed with chILD in a tertiary university hospital in Egypt.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We analysed data of consecutive subjects (aged &lt;18\u2005years) referred for further evaluation at the Children's Hospital, Ain Shams University (Cairo, Egypt). Diagnosis of chILD was made in accordance with the ChILD-EU criteria. The following information was obtained: demographic data, clinical characteristics, chest computed tomography findings, laboratory studies, spirometry, bronchoalveolar lavage and histopathology findings.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>22 subjects were enrolled over 24\u2005months. Median age at diagnosis was 7\u2005years (range 3.5\u201314\u2005years). The most common manifestations were dyspnoea (100%), cough (90.9%), clubbing (95.5%) and tachypnoea (90.9%). Systematic evaluation led to the following diagnoses: hypersensitivity pneumonitis (n=3), idiopathic interstitial pneumonias (n=4), chILD related to chronic granulomatous disease (n=3), chILD related to small airways disease (n=3), post-infectious chILD (n=2), Langerhans cell histiocytosis (n=2), idiopathic pulmonary haemosiderosis (n=2), granulomatous lymphocytic interstitial lung disease (n=1), systemic sclerosis (n=1) and familial interstitial lung disease (n=1). Among the subjects who completed the diagnostic evaluation (n=19), treatment was changed in 13 (68.4%) subjects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Systematic evaluation and multidisciplinary peer review of chILD patients at our tertiary hospital led to changes in management in 68% of the patients. This study highlights the need for an Egyptian chILD network with genetic testing, as well as the value of collaborating with international groups in improving healthcare for children with chILD.<\/jats:p><\/jats:sec>","DOI":"10.1183\/23120541.00880-2020","type":"journal-article","created":{"date-parts":[[2021,3,11]],"date-time":"2021-03-11T17:55:15Z","timestamp":1615485315000},"page":"00880-2020","update-policy":"https:\/\/doi.org\/10.1183\/ers-crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Spectrum of childhood interstitial and diffuse lung diseases at a tertiary hospital in Egypt"],"prefix":"10.1183","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0284-0674","authenticated-orcid":false,"given":"Salma G.","family":"Abdelhady","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eman M.","family":"Fouda","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malak A.","family":"Shaheen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faten A.","family":"Ghazal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed M.","family":"Mostafa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahmed M.","family":"Osman","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew G.","family":"Nicholson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Heba M.","family":"Hamza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"81","published-online":{"date-parts":[[2021,3,11]]},"reference":[{"key":"2024101711065899000_7.2.00880-2020.1","doi-asserted-by":"publisher","DOI":"10.1183\/16000617.0100-2017"},{"key":"2024101711065899000_7.2.00880-2020.2","doi-asserted-by":"publisher","DOI":"10.1136\/thoraxjnl-2015-207349"},{"key":"2024101711065899000_7.2.00880-2020.3","first-page":"57","article-title":"Interstitial lung disease in childhood: clinical and genetic aspects","volume":"9","author":"Kitazawa","year":"2015","journal-title":"Clin Med Insights Circ Respir Pulm Med"},{"key":"2024101711065899000_7.2.00880-2020.4","doi-asserted-by":"crossref","first-page":"1679","DOI":"10.1148\/rg.2017170006","article-title":"Interstitial lung disease in children made easier \u2026 well, almost","volume":"37","author":"Semple","year":"2017","journal-title":"Radiographics"},{"key":"2024101711065899000_7.2.00880-2020.5","doi-asserted-by":"crossref","first-page":"836","DOI":"10.1378\/chest.15-1986","article-title":"Update on diffuse lung disease in children","volume":"149","author":"Vece","year":"2016","journal-title":"Chest"},{"key":"2024101711065899000_7.2.00880-2020.6","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.201305-0923ST"},{"key":"2024101711065899000_7.2.00880-2020.7","doi-asserted-by":"publisher","DOI":"10.1002\/ppul.20114"},{"key":"2024101711065899000_7.2.00880-2020.8","doi-asserted-by":"publisher","DOI":"10.1164\/rccm.200703-393OC"},{"key":"2024101711065899000_7.2.00880-2020.9","doi-asserted-by":"publisher","DOI":"10.1111\/his.12185"},{"key":"2024101711065899000_7.2.00880-2020.10","doi-asserted-by":"crossref","first-page":"1051","DOI":"10.1080\/17476348.2018.1538795","article-title":"Chronic interstitial lung diseases in children: diagnosis approaches","volume":"12","author":"Nathan","year":"2018","journal-title":"Expert Rev Respir Med"},{"key":"2024101711065899000_7.2.00880-2020.11","doi-asserted-by":"publisher","DOI":"10.1186\/1750-1172-5-22"},{"key":"2024101711065899000_7.2.00880-2020.12","doi-asserted-by":"crossref","unstructured":"Cunningham S , Graham C , MacLean M , et al.
