We report a 4\u2010year\u2010old male with poor weight gain, intermittent diarrhea, elevated fecal calprotectin, and persistently elevated erythrocyte sedimentation rate. Endoscopy showed diffuse friable colonic mucosa, and biopsies demonstrated focal active colitis with mild crypt distortion. He was diagnosed with VEO\u2010IBD and treated with mesalamine, infliximab, adalimumab, and upadacitinib, with incomplete response. At age 7, he was hospitalized with fever, cytopenias, and pulmonary infiltrates; human immunodeficiency virus (HIV) testing was positive, with\n                    <jats:italic>Pneumocystis jirovecii<\/jats:italic>\n                    pneumonia and cytomegalovirus viremia. After discontinuing immunosuppression and initiating antiretroviral therapy, gastrointestinal symptoms and inflammatory markers improved. HIV\u2010associated colitis can closely mimic VEO\u2010IBD, and progressive lymphopenia should prompt evaluation for secondary immunodeficiency.\n                  <\/jats:p>","DOI":"10.1002\/jpr3.70245","type":"journal-article","created":{"date-parts":[[2026,10,16]],"date-time":"2026-10-16T10:28:05Z","timestamp":1792146485000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Human immunodeficiency virus infection mimicking very early onset inflammatory bowel disease"],"prefix":"10.1002","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4931-3687","authenticated-orcid":false,"given":"Rasha","family":"Abi Radi Abou Jaoudeh","sequence":"first","affiliation":[{"name":"Division of Gastroenterology, Hepatology, and Nutrition, Children's Healthcare of Atlanta, Department of Pediatrics Emory University Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cary","family":"Sauer","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology, and Nutrition, Children's Healthcare of Atlanta, Department of Pediatrics Emory University Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Teresa","family":"Oh","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology, and Nutrition, Children's Healthcare of Atlanta, Department of Pediatrics Emory University Atlanta Georgia USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,10,16]]},"reference":[{"key":"e_1_2_9_2_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2014.07.023"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11882-017-0724-z"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.3390\/microorganisms9081572"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/ibd\/izz259"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1172\/JCI98642"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1053\/j.gastro.2008.12.073"},{"issue":"4","key":"e_1_2_9_8_1","first-page":"184","article-title":"Acquired immunodeficiency syndrome enteropathy: a perspective","volume":"21","author":"Craig RM","year":"1995","journal-title":"Compr Ther"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/rmv.1935"},{"key":"e_1_2_9_10_1","doi-asserted-by":"publisher","DOI":"10.14202\/vetworld.2020.716-725"}],"container-title":["JPGN Reports"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jpr3.70245","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/jpr3.70245","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/jpr3.70245","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,26]],"date-time":"2026-10-26T11:51:46Z","timestamp":1793015506000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/jpr3.70245"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,16]]},"references-count":9,"alternative-id":["10.1002\/jpr3.70245"],"URL":"https:\/\/doi.org\/10.1002\/jpr3.70245","archive":["Portico"],"relation":{},"ISSN":["2691-171X","2691-171X"],"issn-type":[{"value":"2691-171X","type":"print"},{"value":"2691-171X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,16]]},"assertion":[{"value":"2026-05-16","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-09-03","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2026-10-16","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"jpr3.70245"}}
