Over Time

The treatment of inflammatory bowel disease (IBD) has changed over time with the increasing use of biologics to achieve therapeutic goals. As a result, the cost of treatment increased considerably, making it necessary to develop strategies that could increase access to biological therapies. In this scenario, the biosimilars were developed with the aim of reducing costs, maintaining safety and efficacy compared to the originator. Initially, its use in IBD was based on the extrapolation of studies in other specialties, such as rheumatology. More recently, studies in inflammatory bowel disease have emerged, with favorable results for its use. It is known that there are still knowledge gaps in the use of biosimilars and more experience is needed to increase clinicians’ confidence in their clinical practice. This chapter proposes a review of what is currently known about biosimilars in IBD. It discusses about aspects such as safety, efficacy, interchangeability, immunogenicity and switches.

Sarcopenia is a disorder characterized by a loss of muscle mass which leads to the reduction of muscle strength and a decrease in the quality and quantity of muscle. It was previously thought that sarcopenia was specific to ageing. However, sarcopenia may affect patients suffering from chronic diseases throughout their entire lives. A decreased mass of muscle and bone is common among patients with inflammatory bowel disease (IBD). Since sarcopenia and osteoporosis are closely linked, they should be diagnosed as mutual consequences of IBD. Additionally, multidirectional treatment of sarcopenia and osteoporosis including nutrition, physical activity, and pharmacotherapy should include both disorders, referred to as osteosarcopenia.

Leukocyte Imaging

A prospective study was initiated to compare the clinically proven results concerning localization/extent and activity of inflammatory bowel diseases with those of 111ln-oxine leukocyte imaging. All patients studied were completely examined with barium enema x-ray, clinical and laboratory investigations, and endoscopy with histopathology. A total of 31 leukocyte scans were performed in 15 patients (12 with Crohn’s disease, 3 with ulcerative colitis). The scans were graded by comparing the cell uptake of a lesion (when present) and a bone marrow area providing a count ratio (CR). The inflammatory lesions were correctly localized on 26 leukocyte scans, and in 21 scans the scintigraphically estimated extent of disease was identical to endoscopy. In 5 cases the disease extent was underestimated, 4 scans in patients with relapse of Crohn’s disease were falsely negative, and in one patient with remission truly negative. The scintigraphically assessed disease activity was also in a good agreement with clinical disease activity based on histopathology in all cases. We conclude that leukocyte imaging provides valuable information about localization and activity of inflammatory bowel disease.

Abstract Background Inflammatory bowel diseases are characterized by chronic inflammation of the gastrointestinal tract. In particular, Crohn disease and ulcerative colitis represent the two most common types of clinical manifestations. Extraintestinal manifestations of inflammatory bowel diseases represent a common complications, probably reflecting the systemic inflammation. Renal involvement is reported in 4–23% of cases. However, available data are limited to few case series and retrospective analysis, therefore the real impact of renal involvement is not well defined. Case presentation We report the case of a 10-years old male affected by very early onset unclassified-Inflammatory bowel diseases since he was 1-year old, presenting with a flare of inflammatory bowel diseases associated with acute kidney injury due to granulomatous interstitial nephritis. Of interest, at 7-year-old, he was treated for IgA nephropathy. To our knowledge, no previous reports have described a relapse of renal manifestation in inflammatory bowel diseases, characterized by two different clinical and histological phenotypes. Conclusions The link between the onset of kidney injuries with flares of intestinal inflammation suggest that nephritis maybe considered an extra-intestinal manifestation correlated with active inflammatory bowel disease. However, if granulomatous interstitial nephritis represents a cell-mediated hypersensitivity reaction than a true extraintestinal manifestation of inflammatory bowel diseases is still not clarified. We suggest as these renal manifestations here described may be interpreted as extraintestinal disorder and also considered as systemic signal of under treatment of the intestinal disease.

Abstract Currently over 70 genes known to be causative in very early onset inflammatory bowel disease (VEOIBD) have been identified. In the current issue of Inflammatory Bowel Diseases, 2 articles describing monogenetic forms of VEOIBD are highlighted. One describes a patient with life-threatening VEOIBD and a mutation in ITGA6, illustrating the importance of the epithelial barrier in maintaining mucosal homeostasis. The other describes the presentation and management of 10 patients with VEOIBD secondary to damaging mutations in MVK, resulting in mevalonate kinase deficiency. Though most monogenic causes of VEOIBD remain “private,” understanding the different categories of pathways affected in children with VEOIBD is critical and has already resulted in invaluable insight in the management of patients with VEOIBD and may hold strong implications for the care of IBD overall.

Abstract Background No data on the recently introduced infliximab (IFX) biosimilar SB2 in inflammatory bowel disease (IBD) are available. Methods The Sicilian Prospective Observational Study of Patients With IBD Treated With Infliximab Biosimilar SB2 is a multicenter, observational, prospective study performed among the cohort of the Sicilian Network for Inflammatory Bowel Disease. All consecutive IBD patients starting the IFX biosimilar SB2 from its introduction in Sicily (March 2018) to September 2019 (18 months) were enrolled. Results Two hundred seventy-six patients (Crohn disease: 49.3%, ulcerative colitis: 50.7%) were included: 127 (46.0%) were naïve to IFX and naïve to anti-tumor necrosis factor medications (anti-TNFs), 65 (23.5%) were naïve to IFX and previously exposed to anti-TNFs, 17 (6.2%) were switched from an IFX originator to SB2, 43 (15.6%) were switched from the biosimilar CT-P13 to SB2, and 24 (8.7%) were multiply switched (from IFX originator to CT-P13 to SB2). The cumulative number of infusions of SB2 was 1798, and the total follow-up time was 182.7 patient-years. Sixty-seven serious adverse events occurred in 57 patients (20.7%; incidence rate: 36.7 per 100 patient-year), and 31 of these events caused the withdrawal of the drug. The effectiveness after 8 weeks of treatment was evaluated in patients naïve to IFX (n = 192): 110 patients (57.3%) had steroid-free remission, while 56 patients had no response (29.2%). At the end of follow-up, 72 patients (26.1%) interrupted the treatment, without significant differences in treatment persistency estimations between the five groups (log-rank P = 0.15). Conclusions The safety and effectiveness of SB2 seem to be overall similar to those reported for the IFX originator and CT-P13.
