Timing of Last Preoperative Dose of Infliximab Does Not Increase Postoperative Complications in Inflammatory Bowel Disease Patients.

ABSTRACT: The association between preoperative use of infliximab and postoperative complications in patients with inflammatory bowel disease (IBD) is a subject of continued debate. Results from studies examining an association between the timing of last preoperative dose of infliximab and postoperative complications remain inconsistent.To assess whether timing of last dose of infliximab prior to surgery affects the rate of postoperative complications in patients with Crohn's disease or ulcerative colitis.Retrospective chart review of IBD patients who have undergone surgery while receiving therapy with infliximab was conducted. Forty-seven patients were included in the analysis.No significant association was found between timing of infliximab and the rate of postoperative complications. Age, gender, disease type, steroid use, preoperative status, surgery type, or surgeon type was not associated with increased rate of postoperative complications.Timing of last dose of infliximab does not affect the rate of postoperative complications in patients with Crohn's disease or ulcerative colitis.

Project description:BackgroundVaccination has been effective in preventing COVID-19 infections and related mortality. However, waning immunity after two-dose vaccination prompted health authorities to recommend a third dose of COVID-19 vaccine to boost immunity. The aim of our study was to assess willingness to receive a third (booster) dose among patients with inflammatory bowel disease (IBD).MethodsA cross-sectional study was performed at an IBD tertiary care center. Patients were recruited at the infusion room from 1 January 2022 to 31 March 2022. The primary outcome was the prevalence of a third (booster) dose of the BNT162b2 vaccine in infliximab- or vedolizumab-treated patients with IBD. The secondary outcome evaluated whether the prevalence of a third (booster) dose of the BNT162b2 vaccine differed based on type of COVID-19 vaccine, gender, age, type of biologic therapy, and citizenship.ResultsIn total, 499 patients with IBD were included in this study. The median age was 34.5 years, and 60% had ulcerative colitis (UC). Among the study participants, 302 (60.5%) patients were vaccinated with BNT162b2, and 197 (39.5%) were vaccinated with ChAdOx1 nCoV-19. Of the total number of participants, 400 (80.2%) were receiving infliximab, and 99 (19.8%) were receiving vedolizumab. Overall, 290 (58.1%) of the included patients were willing to receive the third (booster) dose. Patients vaccinated with BNT162b2 were more likely to be willing to receive a booster dose compared to patients vaccinated with ChAdOx1 nCoV-19 (201 (66.5%) vs. 103 (52.0%), p = 0.014). Infliximab-treated patients were more likely to be willing to receive a booster dose compared to patients receiving vedolizumab (310 (77.5%) vs. 62 (62.6%), p = 0.002). There was no statistical difference in willingness to receive a booster dose in terms of age, nationality, or gender.ConclusionsThe percentage of patients with IBD willing to receive or having already received a third (booster) dose of BNT162b2 vaccine was lower compared to the general population. In addition, patients who received two doses of BNT162b2 vaccines were more likely to be willing to receive a third (booster) dose compared to patients who received ChAdOx1 nCoV-19. Patients treated with infliximab were more likely to be willing to receive a third (booster) dose of COVID-19 vaccine.

Project description:BackgroundPostoperative complications after major gastrointestinal surgery are a major contributor to hospital costs. Thus, reducing postoperative complications is a key target for cost-containment strategies. We aimed to evaluate the relationship between postoperative complications and hospital costs following small bowel resection.MethodsPostoperative complications were recorded for 284 adult patients undergoing major small bowel resection surgery between January 2013 and June 2018. Complications were defined and graded according to the Clavien-Dindo classification system. In-hospital cost of index admission was calculated using an activity-based costing methodology; it was reported in US dollars at 2019 rates. Regression modeling was used to investigate the relationships among a priori selected perioperative variables, complications, and costs.FindingsThe overall complication prevalence was 81.6% (95% CI: 85.7-77.5). Most complications (69%) were minor, but 22.9% of patients developed a severe complication (Clavien-Dindo grades III or IV). The unadjusted median total hospital cost for patients with any complication was 70% higher than patients without complications (median [IQR] USD 19,659.64 [13,545.81-35,407.14] vs. 11,551.88 [8,849.46-15,329.87], P < 0.001). The development of 1, 2, 3, and ≥ 4 complications increased hospital costs by 11%, 41%, 50%, and 195%, respectively. Similarly, more severe complications incurred higher hospital costs (P < 0.001). After adjustments were made (for the Charlson Comorbidity Index, anemia, surgical urgency and technique, intraoperative fluid administration, blood transfusion, and hospital readmissions), a greater number and increased severity of complications were associated with a higher adjusted median hospital cost. Patients who experienced complications had an adjusted additional median cost of USD 4,187.10 (95% CI: 1,264.89-7,109.31, P = 0.005) compared to those without complications.ConclusionsPostoperative complications are a key target for cost-containment strategies. Our findings demonstrate a high prevalence of postoperative complications following small bowel resection surgery and quantify their associated increase in hospital costs.Trial registrationAustralian Clinical Trials Registration number: 12620000322932.

Project description:BackgroundInadequate infliximab (IFX) drug exposure remains a clinical challenge and leads to high loss of response rates and therapy failure in inflammatory bowel disease (IBD). We aimed to determine the feasibility and pilot effectiveness of a novel, web-based, mobile IFX dosing calculator (mIDC) for therapy optimization.MethodsWe developed an mIDC leveraging the known clinical variables of C-reative protein (CRP), albumin, patient's weight, disease activity indices, calprotectin, drug trough levels, and antibodies to IFX that significantly affect pharmacokinetics and/or outcomes. A prospective observational cohort study in pediatric and young adult IBD patients receiving maintenance IFX was performed. System-wide practice adoption of mIDC was achieved through a quality improvement (QI) initiative within a hospital-based infusion unit.ResultsForty-nine patients (median age: 16.0 years; 55% female; 65% Crohn's disease) were followed over 9 months. mIDC recommendations for dose optimization were followed by the treating physicians in 198 (89%) out of 222 infusions. Twenty-eight (13%) of 222 mIDC recommendations were to escalate IFX dosing; 15 (54%) of 28 escalation recommendations were declined, and these patients were more likely to already be receiving IFX dose intensification compared with those in whom escalation recommendations were followed (P < 0.05). From mIDC initiation to end of follow-up, mean albumin levels remained unchanged at 3.8 g/dL. Median CRP remained unchanged at 2 g/L. Median calprotectin levels showed a downward trend from 30 to 27 μg/g (n = 9, P < 0.05). The percentage of patients undergoing therapeutic drug monitoring in clinical care increased from 34% to 86% with the QI initiative. The target median IFX trough goal of >5 μg/mL was achieved with 81% probability throughout the QI initiative, an increase of 12% compared with pre-QI values.ConclusionsThe use of a novel mIDC is feasible and potentially effective, facilitating both standardization and individualization of therapy in clinical care. mIDC appears to be a practical IFX dosing tool for point-of-care use, leveraging individual pharmacokinetic considerations.
