We aimed to determine the prevalence and underlying causes of recurrent\/persistent pneumonia in children in Upper Egypt.   Settings: Assiut University Children Hospital, Assiut, Egypt. \u00a0 Methods: Patients with pneumonia admitted to the hospital during 2 years were investigated (microbiological, biochemical, immunological and radiological tests) for recurrent\/persistent pneumonia to determine its prevalence and to find out the underlying causes. \u00a0 Results: 113 out of 1228 patients (9.2%) met the diagnosis of recurrent\/persistent pneumonia. Identified causes were;\u00a0 aspiration syndromes (17.7%), pulmonary TB (14%), congenital heart disease (11.5%), bronchial asthma (9.7%), immune deficiency disorders (8.8%) and vitamin D deficiency rickets (7%). Other causes included; congenital anomalies of the respiratory tract, interstitial lung diseases, bronchiectasis, and sickle cell anemia. No predisposing factors could be identified in 15% of cases.   Conclusion: Approximately 1 in 10 children with pneumonia in our locality had recurrent\/persistent pneumonia. The most frequent underlying cause for recurrent\/persistent pneumonia in children in Upper  Egypt is aspiration syndromes, followed by pulmonary TB.<\/jats:p>","DOI":"10.4084\/mjhid.2013.028","type":"journal-article","created":{"date-parts":[[2013,5,2]],"date-time":"2013-05-02T03:19:42Z","timestamp":1367464782000},"page":"e2013028","source":"Crossref","is-referenced-by-count":13,"title":["RECURRENT\/PERSISTENT PNEUMONIA AMONG CHILDREN IN UPPER EGYPT"],"prefix":"10.4084","volume":"5","author":[{"given":"Khaled","family":"Saad","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"2554","published-online":{"date-parts":[[2013,4,18]]},"updated-by":[{"DOI":"10.4084\/mjhid.2014.024","type":"retraction","label":"Retraction","source":"retraction-watch","updated":{"date-parts":[[2014,3,22]],"date-time":"2014-03-22T00:00:00Z","timestamp":1395446400000},"record-id":"2985"}],"container-title":["Mediterranean Journal of Hematology and Infectious Diseases"],"original-title":[],"link":[{"URL":"https:\/\/www.mjhid.org\/mjhid\/article\/download\/2013.028\/667","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.mjhid.org\/mjhid\/article\/download\/2013.028\/668","content-type":"text\/html","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.mjhid.org\/mjhid\/article\/download\/2013.028\/667","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,1,13]],"date-time":"2026-01-13T11:25:23Z","timestamp":1768303523000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.mjhid.org\/mjhid\/article\/view\/2013.028"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,4,18]]},"references-count":0,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2013,1,1]]}},"URL":"https:\/\/doi.org\/10.4084\/mjhid.2013.028","relation":{},"ISSN":["2035-3006"],"issn-type":[{"value":"2035-3006","type":"electronic"}],"subject":[],"published":{"date-parts":[[2013,4,18]]}}}
