Introduction. Inflammatory bowel disease (IBD), which includes Crohn’s disease (CD) and ulcerative colitis (UC), is a multifactorial intestinal disorder but its precise etiology remains elusive. As the cells of the intestinal mucosa have high energy demands, mitochondria may play a role in IBD pathogenesis. The present study is aimed at evaluating the expression levels of mitochondrial oxidative phosphorylation (OXPHOS) complexes in IBD. Material and Methods. 286 intestinal biopsy samples from the terminal ileum, ascending colon, and rectum from 124 probands (34 CD, 33 UC, and 57 controls) were stained immunohistochemically for all five OXPHOS complexes and the voltage-dependent anion-selective channel 1 protein (VDAC1 or porin). Expression levels were compared in multivariate models including disease stage (CD and UC compared to controls) and age (pediatric/adult). Results. Analysis of the terminal ileum of CD patients revealed a significant reduction of complex II compared to controls, and a trend to lower levels was evident for VDAC1 and the other OXPHOS complexes except complex III. A similar pattern was found in the rectum of UC patients: VDAC1, complex I, complex II, and complex IV were all significantly reduced, and complex III and V showed a trend to lower levels. Reductions were more prominent in older patients compared to pediatric patients and more marked in UC than CD. Conclusion. A reduced mitochondrial mass is present in UC and CD compared to controls. This is potentially a result of alterations of mitochondrial biogenesis or mitophagy. Reductions were more pronounced in older patients compared to pediatric patients, and more prominent in UC than CD. Complex I and II are more severely compromised than the other OXPHOS complexes. This has potential therapeutic implications, since treatments boosting biogenesis or influencing mitophagy could be beneficial for IBD treatment. Additionally, substances specifically stimulating complex I activity should be tested in IBD treatment.

Background: Infusion reactions (IRs) are the most common adverse events (AEs) of infliximab (IFX) treatment in patients with inflammatory bowel disease (IBD). Prophylactic premedication (PM) with corticosteroids or antihistamines prior to IFX infusions has been used in clinical practice, but its efficacy is not known. The aim of this study was to assess the influence of steroid PM on IR incidence in pediatric patients with IBD receiving IFX. Methods: We performed a case–control study that included pediatric patients with IBD receiving IFX. Patients were divided into four subgroups according to the agent and PM they received: Remicade (original drug) + PM, and two biosimilars—Reshma +/− PM, and Flixabi—PM. At our site, until 2018, PM with steroids was used as a part of standard IFX infusion (PM+); however, since then, this method has no longer been administered (PM−). IRs were divided into mild/severe reactions. Differences between subgroups were assessed with the appropriate chi-square test. Multivariate logistic regression was used to assess associations between PM and IR incidence, correcting for co-medication usage. Results: There were 105 children (55 PM+, 44 male, mean age 15 years) included in the study who received 1276 infusions. There was no difference between the PM+ and PM− subgroups, either in incidence of IR (18.2% vs. 16.0% of patients, p > 0.05) or in percentage of infusions followed by IR (2.02% vs. 1.02% of infusions, p > 0.5). The OR of developing IR when using PM was 0.34, and the difference in IRs ratio in PM+ and PM− patients was not statistically significant (95% CI, 0.034–1.9). There were 11/18 (61.1%) severe IRs (anaphylactic shock) reported in all patients (both PM+ and PM−). Conclusion: At our site, the incidence of IR was low, and PM did not decrease the incidence of IR in pediatric patients with IBD receiving IFX. These results indicate that PM with steroids should not be a standard part of IFX infusion to prevent IR.
