Relevant clinical data\u2014including patient characteristics, IBD treatments, and respiratory outcomes\u2014were extracted from electronic medical records. Statistical analyses were performed using SPSS version 30, employing chi\u2010square tests and logistic regression for univariate and multivariate analyses, with a significance threshold set at\n p<\/jats:italic>\n \u2009<\u20090.05.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Total of 184 IBD patients with 288 episodes of respiratory symptoms underwent respiratory swabs and PCR. Overall detectable pathogens on respiratory swab were 14% (\n n<\/jats:italic>\n \u2009=\u200940), including 60% (\n n<\/jats:italic>\n \u2009=\u200924) COVID, 5% (\n n<\/jats:italic>\n \u2009=\u20092) RSV, 8% (\n n<\/jats:italic>\n \u2009=\u20093) Influenza and 28% (\n n<\/jats:italic>\n \u2009=\u200911) other viruses. Of the total IBD patients, the median age was 37.5 [IQR 27\u201355], median disease duration 7\u2009years [IQR 3\u201314] and the majority diagnosed with ulcerative colitis (\n n<\/jats:italic>\n \u2009=\u200997, 52.7%) or Crohn's disease (\n n<\/jats:italic>\n \u2009=\u200980, 43.5%). The median age was 37.5\u2009years (interquartile range [IQR] 28\u201355.5) in the pathogen positive detection group and 38\u2009years (IQR 27\u201356.25) in the undetectable pathogen group. Most of the patients with a positive detectable respiratory pathogen had ulcerative colitis (\n n<\/jats:italic>\n \u2009=\u200922, 57.9%) or Crohn's disease (\n n<\/jats:italic>\n \u2009=\u200918, 45%). We found no significant effect of conventional or advanced IBD therapy on respiratory pathogen detection including infliximab (\n p<\/jats:italic>\n \u2009=\u20090.856), adalimumab (\n p<\/jats:italic>\n \u2009=\u20090.148), vedolizumab (\n p<\/jats:italic>\n \u2009=\u20090.957), ustekinumab (\n p<\/jats:italic>\n \u2009=\u20090.976), immunomodulator(s) (\n p<\/jats:italic>\n \u2009=\u20090.560, 0.573) or 5\u2010ASA (\n p<\/jats:italic>\n \u2009=\u20090.758). However, concurrent prednisolone use significantly increased the risk of detectable pathogens (OR 2.78 [95% CI 1.07\u20137.19],\n p<\/jats:italic>\n \u2009=\u20090.035).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n This study found no increase in respiratory pathogen detection in IBD patients taking advanced therapies or immunomodulators, but concurrent prednisolone use was a significant risk factor. This suggests the importance of reducing steroid exposure via early introduction of steroid\u2010sparing agents.<\/jats:p>\n <\/jats:sec>","DOI":"10.1002\/jgh3.70456","type":"journal-article","created":{"date-parts":[[2026,8,6]],"date-time":"2026-08-06T03:43:02Z","timestamp":1785987782000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The Burden of Viral Respiratory Infections in Immunosuppressed Inflammatory Bowel Disease Patients"],"prefix":"10.1002","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-7750-6032","authenticated-orcid":false,"given":"D.","family":"Huynh","sequence":"first","affiliation":[{"name":"Mater Hospital Brisbane South Brisbane Australia"},{"name":"Faculty of Medicine The University of Queensland Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E.","family":"Khoo","sequence":"additional","affiliation":[{"name":"Mater Hospital Brisbane South Brisbane Australia"},{"name":"Faculty of Medicine The University of Queensland Brisbane Australia"},{"name":"Mater Research Institute South Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5977-3978","authenticated-orcid":false,"given":"A.","family":"Shanmuga Anandan","sequence":"additional","affiliation":[{"name":"Mater Hospital Brisbane South Brisbane Australia"},{"name":"Faculty of Medicine The University of Queensland Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5256-7672","authenticated-orcid":false,"given":"J.","family":"Begun","sequence":"additional","affiliation":[{"name":"Mater Hospital Brisbane South Brisbane Australia"},{"name":"Faculty of Medicine The University of Queensland Brisbane Australia"},{"name":"Mater Research Institute South Brisbane Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,5]]},"reference":[{"issue":"9","key":"e_1_2_10_2_1","first-page":"1880","article-title":"Cause\u2010Specific Mortality and 30\u2010Year Relative Survival of Crohn's Disease and Ulcerative Colitis","volume":"19","author":"Selinger C.
