In Qatar, there are no data on hepatitis D virus infection among patients positive for hepatitis B surface antigen (HBsAg). Aims: To determine the seroprevalence of hepatitis D virus infection among patients with chronic hepatitis B virus infection in Qatar and assess the characteristics of these patients. Methods: This was a retrospective cohort study of all HBsAg-positive individuals tested for hepatitis D virus between 1 January 2010 and 29 December 2019 within the Hamad Medical Corporation. Data were retrieved from electronic records and included demographic and clinical information of the patients. Results: Of the 2348 HBsAg-positive patients, 125 were positive for hepatitis D virus (seroprevalence 5.3%). The median age of hepatitis D positive patients was significantly higher than for hepatitis D negative patients (P = 0.001). Most of the patients with hepatitis D had a hepatitis B viral load &lt; 2000 IU\/mL (53.6%) and were negative for hepatitis B e antigen (93.6%). A significantly greater proportion of hepatitis D positive patients than hepatitis D negative patients were infected with hepatitis C virus (P &lt; 0.001), and had liver cirrhosis (P &lt; 0.001) and hepatocellular carcinoma (P = 0.006). Conclusions: Hepatitis D virus infection is associated with lower hepatitis B virus viraemia and more advanced liver disease in the study population.<\/jats:p>","DOI":"10.26719\/emhj.22.081","type":"journal-article","created":{"date-parts":[[2022,10,20]],"date-time":"2022-10-20T12:54:27Z","timestamp":1666270467000},"page":"840-846","source":"Crossref","is-referenced-by-count":2,"title":["Seroprevalence and clinical outcome of hepatitis D infection in Qatar"],"prefix":"10.26719","volume":"28","author":[{"given":"Tasneem","family":"Abdallah","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tawheeda","family":"Ibrahim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammed","family":"Hajmusa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammed","family":"Abdulgayoom","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Afra","family":"Elhassan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alyaa","family":"Abusabeib","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mona","family":"Babikir","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaimaa","family":"Abdelrahim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanne","family":"Daghfal","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Moutaz","family":"Derbala","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"11263","published-online":{"date-parts":[[2022,11,30]]},"container-title":["Eastern Mediterranean Health Journal"],"original-title":[],"link":[{"URL":"https:\/\/applications.emro.who.int\/EMHJ\/V28\/11\/1020-3397-2022-2811-840-846-eng.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,11,30]],"date-time":"2022-11-30T08:31:05Z","timestamp":1669797065000},"score":1,"resource":{"primary":{"URL":"https:\/\/applications.emro.who.int\/EMHJ\/V28\/11\/1020-3397-2022-2811-840-846-eng.pdf"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,11,30]]},"references-count":0,"journal-issue":{"issue":"11","published-online":{"date-parts":[[2022,11,30]]},"published-print":{"date-parts":[[2022,11,30]]}},"URL":"https:\/\/doi.org\/10.26719\/emhj.22.081","relation":{},"ISSN":["1020-3397","1687-1634"],"issn-type":[{"value":"1020-3397","type":"print"},{"value":"1687-1634","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,11,30]]}}}
