The therapeutical effect is very good not only for induction of remission of the intestinal inflammation, but also for a long-term maintenance treatment. For some patients, however, BT is associated with the occurrence of sometimes serious side effects. Their pathogenesis is not known yet and in some cases these serious side effects are the cause of the termination of the treatment. Methods: In the period 2007–2012, 136 patients with IBD TNF-α were treated at the Department of Internal Medicine II of the University Hospital in Olomouc. In this set of patients, the occurrence of serious side effects of TNF-α was observed

within the dispensarization. The difference in the occurrence of side events was compared with the control set of 114 patients with IBD, who underwent only conventional therapy (aminosalicylates, corticosteroids, immunosuppressants). Linsitinib The observed side effects included skin, articulary, CH5424802 mw ocular, infectious, metabolic and hematopoietic disorders. The data were statistically processed

using standard descriptive methods for continuous data. Results: The serious side effects were documented in 12 (8.8%) patients with TNF-α therapy; the most common complications were skin complications (54.3%). In the set of patients under the conventional therapy, the side effects of the treatment have been reported in 8 (7.0%) patients, mostly involving hematopoietic disorders (61.2%). The observed difference of occurrence of serious side effects was not statistically significant (p = 0.11). Conclusion: In the last decade, the introduction of BT has caused a significant change in the routine clinical treatment of IBD. It turns out that this treatment is relatively safe, the incidence of serious side effects is not higher than when using conventional drug therapy.

It is necessary to indicate the TNF-α treatment properly, the patient must be carefully examined before the initiation of the treatment and intensively monitored during the course of the treatment.

Recent years, researchers find TNF ligand-related molecule-1A (TL1A) is a new member of tumor necrosis factor superfamily (TNFSF), which can bind DcR3 to induce some inflammation, also may provide a new biological therapeutic target with IBD.
