RT Journal Article SR Electronic T1 Influence of comorbidities on treatment considerations for first-line biologic prescribing in patients with inflammatory bowel disease in the UK JF Frontline Gastroenterology JO Frontline Gastroenterol FD BMJ Publishing Group Ltd SP 490 OP 496 DO 10.1136/flgastro-2021-101995 VO 13 IS 6 A1 Ayesha Akbar A1 Tim Orchard A1 Nick Powell A1 Christian Selinger A1 Clare tibbatts YR 2022 UL http://fg.bmj.com/content/13/6/490.abstract AB Background Anti-tumour necrosis factor (anti-TNF) therapies are the most commonly used biologics for inflammatory bowel disease (IBD), but for patients with a comorbidity, newer agents may be a more appropriate treatment choice.Aims To investigate the impact of comorbidities in patients with IBD, on first-line biologic prescribing habits of IBD-specialist healthcare practitioners in the UK.Methods IBD-specialist physicians and nurses were asked to answer an online survey, considering different prescribing scenarios in ulcerative colitis (UC) and Crohn’s disease (CD). Respondents could indicate a preference for anti-TNFs or newer biologics, both in the absence and presence of 10 common comorbidities.Results A total of 120 IBD-specialist healthcare professionals (HCPs) completed the survey. In the absence of comorbidities, anti-TNFs were favoured; infliximab was the preferred first-line biologic in both UC and CD (43% and 37% of respondents, respectively). On introducing comorbidities, the largest shift in prescribing behaviour was for vedolizumab, with preference increasing by 27% and 21%, compared with infliximab, which fell by 14% and 9% in UC and CD, respectively. Chronic/recurring infection (46%), congestive heart failure (≤44%) and malignancies (≤43%) were the most commonly selected comorbidities for vedolizumab treatment.Conclusions Clinicians adapt their biologic prescribing habits in patients with IBD with comorbidities, considering known contraindications and precautions. A preference for vedolizumab is evident in many cases, however, for several comorbid scenarios, including demyelinating disorders, chronic obstructive pulmonary disease and malignancy, anti-TNFs are prescribed despite known risks. It is important that continual re-evaluation of the IBD treatment landscape is undertaken by HCPs, in alignment with recommendations in published guidelines.Data available within the article or its supplementary materials.
