The literature on AIH in the Middle East, including Jordan, is scarce; therefore, this study aimed to determine the clinical characteristics of AIH in an understudied population. This retrospective chart review study was conducted on AIH patients who presented to Jordan University Hospital over a seven-year period (2014\u20132020). Retrieved data included sociodemographics, liver function tests, autoimmune serologic markers, viral hepatitis serology, findings on liver biopsies, treatment regimens, post-therapy outcomes and treatment-related complications. The total number of AIH patients included in the study was 30, divided as follows: type 1 AIH (n = 17, 56.7%), type 2 AIH (n = 2, 6.7%), seronegative AIH (n = 9, 30.0%), and two patients who had AIH-primary biliary cirrhosis overlap syndrome (6.7%). The mean age at diagnosis was 44 years (standard deviation: 17 years), with a female predominance (n = 25, 83.3%). Acute presentation was seen among 18 patients (60.0%). Mild to moderate fibrosis (F1 and F2 on METAVIR scoring system) without cirrhosis was observed among patients who underwent liver biopsies (10\/19, 52.6%). The majority of patients (73.3%) were initially treated with prednisone, with azathioprine combination in 16.7% of the patients. At 6 months post initial treatment, twenty patients (66.7%) achieved biochemical remission, four patients had incomplete response, two patients failed to improve (one died during the induction of remission period due to AIH-related complications), and four patients were lost to follow-up. This study provided an updated overview of AIH in Jordan. The results showed typical female predominance, and interestingly high rates of acute presentation and seronegative disease. Future longitudinal studies are recommended to address the nature and long-term prognosis of AIH in Jordan.<\/jats:p>","DOI":"10.3390\/jcm12020629","type":"journal-article","created":{"date-parts":[[2023,1,13]],"date-time":"2023-01-13T02:29:57Z","timestamp":1673576997000},"page":"629","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Clinical Characteristics of Autoimmune Hepatitis in a Middle Eastern Population: A Tertiary Care Center Experience"],"prefix":"10.3390","volume":"12","author":[{"given":"Tarek A.","family":"Tamimi","sequence":"first","affiliation":[{"name":"Section of Gastroenterology, Department of Internal Medicine, Jordan University Hospital, Amman 11942, Jordan"},{"name":"Department of Internal Medicine, School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0165-9670","authenticated-orcid":false,"given":"Malik","family":"Sallam","sequence":"additional","affiliation":[{"name":"Department of Pathology, Microbiology and Forensic Medicine, School of Medicine, University of Jordan, Amman 11942, Jordan"},{"name":"Department of Clinical Laboratories and Forensic Medicine, Jordan University Hospital, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Deema","family":"Rayyan","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randa","family":"Farah","sequence":"additional","affiliation":[{"name":"Department of Internal Medicine, School of Medicine, University of Jordan, Amman 11942, Jordan"},{"name":"Section of Nephrology, Department of Internal Medicine, Jordan University Hospital, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dana","family":"Alkhulaifat","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3517-3601","authenticated-orcid":false,"given":"Abdallah","family":"Al-Ani","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Reem","family":"Elmusa","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Said","family":"Sharawi","sequence":"additional","affiliation":[{"name":"School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Omar","family":"Tanash","sequence":"additional","affiliation":[{"name":"Section of Gastroenterology, Department of Internal Medicine, Jordan University Hospital, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0421-5143","authenticated-orcid":false,"given":"Yaser","family":"Rayyan","sequence":"additional","affiliation":[{"name":"Section of Gastroenterology, Department of Internal Medicine, Jordan University Hospital, Amman 11942, Jordan"},{"name":"Department of Internal Medicine, School of Medicine, University of Jordan, Amman 11942, Jordan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18017","DOI":"10.1038\/nrdp.2018.17","article-title":"Autoimmune hepatitis","volume":"4","author":"Vergani","year":"2018","journal-title":"Nat.
