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 Objective Vedolizumab (VDZ) has been incriminated in the occurrence of articular manifestations in patients with inflammatory bowel diseases (IBDs). The aim of this study was to describe musculoskeletal manifestations occurring in IBD patients treated by VDZ and to identify risk factors. Methods In this retrospective monocentric study, we included all consecutive patients treated by VDZ for IBD in our hospital. Incident musculoskeletal manifestations occurring during VDZ treatment were analysed and characteristics of patients with and without articular inflammatory manifestations were compared. Results Between 2013 and 2017, 112 patients were treated with VDZ for IBD: ulcerative colitis (n = 59), Crohn’s disease (n = 49) and undetermined colitis (n = 4). Four patients (3.6%) had a history of SpA, whereas 13 (11.6%) had a history of peripheral arthralgia. Some 102 (91.1%) patients had previously received anti-TNF. After a mean (S.d.) follow-up of 11.4 (8.6) months, 32 (28.6%) patients presented 35 musculoskeletal manifestations, of which 18 were mechanical and 17 inflammatory. Among the latter, 11 had axial or peripheral SpA, 5 had early reversible arthralgia and 1 had chondrocalcinosis (n = 1). Among the 11 SpA patients, only 3 (2.6%) had inactive IBD and may be considered as paradoxical SpA. The only factor associated with occurrence of inflammatory manifestations was history of inflammatory articular manifestation [7/16 (43.8%) vs 10/80 (12.5%), P = 0.007]. Conclusion Musculoskeletal manifestations occurred in almost 30% of IBD patients treated with VDZ, but only half of them were inflammatory. Since most of the patients previously received anti-TNF, occurrence of inflammatory articular manifestations might rather be linked to anti-TNF discontinuation than to VDZ itself.

Inflammasomes are intracellular multiprotein complexes that coordinate the maturation of interleukin (IL)-1β and IL-18 in response to pathogens and metabolic danger. Both cytokines have been linked to intestinal inflammation. However, recently evolving concepts ascribe a major role to the inflammasome in maintaining intestinal homeostasis. This review recapitulates its position in the development of inflammatory bowel disease, thereby outlining a model in which hypo- as well as hyperfunctionality can lead to an imbalance of the system, depending on the specific cell population affected. In the epithelium, the inflammasome is essential for regulation of permeability and epithelial regeneration through sensing of commensal microbes, while excessive inflammasome activation within the lamina propria contributes to severe intestinal inflammation.
