BACKGROUND Industry payments can lead to financial conflicts of interest (FCOI) among authors of clinical practice guidelines (CPGs). Guidelines for inflammatory bowel disease (IBD) may be at particularly high risk. We determined the prevalence of FCOI in IBD CPGs produced by various gastroenterology societies. METHODS We conducted a cross-sectional analysis of FCOI disclosure among CPGs related to the management of IBD. We ascertained the prevalence and types of FCOI for each guideline and determined adherence to National Academy of Medicine (NAM) standards. FCOI disclosures were compared between societies producing CPGs. RESULTS We identified 11 relevant CPGs with 173 total authors. There were 117 (68%) authors who declared a payment. A total of 107 (62%) authors declared FCOI related to a medication recommended in the guideline. There was a significant difference (P < 0.001) between the proportion of authors with FCOI between countries or regions. Authors of US CPGs had a significantly lower FCOI prevalence (19%) compared with other societies. Authors of UK CPGs had a significantly lower FCOI prevalence (56%) compared with Canadian (84%) and European (94%) CPGs. Three (27%) guidelines adhered to both NAM standards. CONCLUSIONS A substantial portion of authors of IBD CPGs had FCOI. Our study found a significant difference in FCOI prevalence based on CPG sponsor nationality. Most CPGs for IBD did not adhere to NAM standards for FCOI disclosure.

Background. Aseptic abscesses (AA) are sterile lesions that represent an extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD). Though Canada has the highest prevalence of IBD in the world, reports of IBD-associated AA are absent in Canada. This may represent a different IBD phenotype or underrecognition and underreporting. Purpose. To explore AA as a possible EIM of IBD and evaluate clinical and investigative findings among patients with IBD-associated AA. Methods. Retrospective chart and literature reviews were performed to find cases of IBD-associated AA at our institution and in the literature. Results. We identified 2 cases of IBD-associated AA in our institution. Both patients had ulcerative colitis and presented with fever, abdominal pain, and weight loss. Radiological workup and aspiration showed sterile splenic abscesses. The AA were unresponsive to antibiotics. One patient improved on corticosteroids and one underwent splenectomy. We retrieved 37 cases of IBD-associated AA from the literature. All patients showed no evidence of infection, failed to resolve with antibiotics, and, if attempted, improved on corticosteroids. Conclusions. Our cases are the first reported in Canada. They support literature which suggests AA as an EIM of IBD and may help increase recognition and reporting of this phenomenon.
