Abstract
BACKGROUND Anti-drug antibodies are associated with treatment failure to anti-TNF agents in patients with inflammatory bowel disease (IBD). AIM To assess whether immunogenicity to a patient's first anti-TNF agent would be associated with immunogenicity to the second, irrespective of drug sequence METHODS: We conducted a UK-wide, multicentre, retrospective cohort study to report rates of immunogenicity and treatment failure of second anti-TNF therapies in 1058 patients with IBD who underwent therapeutic drug monitoring for both infliximab and adalimumab. The primary outcome was immunogenicity to the second anti-TNF agent, defined at any timepoint as an anti-TNF antibody concentration ≥9 AU/ml for infliximab and ≥6 AU/ml for adalimumab. RESULTS In patients treated with infliximab and then adalimumab, those who developed antibodies to infliximab were more likely to develop antibodies to adalimumab, than patients who did not develop antibodies to infliximab (OR 1.99, 95%CI 1.27-3.20, p = 0.002). Similarly, in patients treated with adalimumab and then infliximab, immunogenicity to adalimumab was associated with subsequent immunogenicity to infliximab (OR 2.63, 95%CI 1.46-4.80, p < 0.001). For each 10-fold increase in anti-infliximab and anti-adalimumab antibody concentration, the odds of subsequently developing antibodies to adalimumab and infliximab increased by 1.73 (95% CI 1.38-2.17, p < 0.001) and 1.99 (95%CI 1.34-2.99, p < 0.001), respectively. Patients who developed immunogenicity with undetectable drug levels to infliximab were more likely to develop immunogenicity with undetectable drug levels to adalimumab (OR 2.37, 95% CI 1.39-4.19, p < 0.001). Commencing an immunomodulator at the time of switching to the second anti-TNF was associated with improved drug persistence in patients with immunogenic, but not pharmacodynamic failure. CONCLUSION Irrespective of drug sequence, immunogenicity to the first anti-TNF agent was associated with immunogenicity to the second, which was mitigated by the introduction of an immunomodulator in patients with immunogenic, but not pharmacodynamic treatment failure.

Abstract
PURPOSE We studied preoperative and perioperative factors with particular attention to the role of immunomodulatory medication, which may impact the incidence of pouch-related septic complications. METHODS A retrospective review of data from patients who underwent ileal pouch surgery during a 20-year period from 1985 to 2005 was performed. Preoperative use of immunomodulatory medication along with perioperative clinical, surgical, and disease variables were recorded. Patients were monitored for pouch-related sepsis in the early (within 30 days of surgery) and late (after 30 days of surgery) postoperative periods. Univariate and multivariate logistic regression analysis was performed. RESULTS There were 445 patients (206 females; 46.4 percent). Median age was 36 (interquartile range, 27-46) years. Median follow-up period was 52 (interquartile range, 26-86) months. Complete data were available for 335 patients. Early sepsis was seen in 58 patients (17.3 percent). Another 22 patients (6.5 percent) developed late sepsis. On multivariate analysis, only steroid use remained predictive of higher rates of early sepsis (odds ratio, 1.81; 95 percent confidence interval, 1.02-3.45; P=0.002). Likewise on multivariate analysis, both male gender (odds ratio, 0.24; 95 percent confidence interval, 0.09-0.71; P=0.007) and 5-aminosalicylic-acid use (odds ratio, 0.22; 95 percent confidence interval, 0.08-0.76; P=0.023) remained predictive of lower rates of sepsis. CONCLUSIONS Preoperative steroid use is associated with higher rates of early but not late pouch-related septic complications. We recommend that patients be weaned of steroids before ileal pouch surgery or be warned of the higher risk of postoperative sepsis.
