PUCCINI: Safety of Anti-TNF in the Perioperative Setting

Preoperative Optimization of Crohn's Patients before Abdominopelvic Surgery

In this article, we review and identify modifiable risk factors associated with postoperative complications of Crohn's disease. We highlight the importance of factors such as nutrition, corticosteroids, immunomodulators, abscesses, ideal timing of surgery, and biologic and small-molecule therapy on surgical outcomes. Herein, we discuss the strategies for attenuating these risk factors. Special consideration is given to venous thromboembolism prophylaxis in this patient population.

Janus kinase inhibitors in the management of acute severe ulcerative colitis: a comprehensive review

BACKGROUND

One-third of patients with acute severe ulcerative colitis (ASUC) are steroid-refractory. Cyclosporine and infliximab are currently the mainstays of salvage therapy. Janus kinase inhibitors (JAKi) could play a role in the treatment of ASUC.

AIM

To review the evidence on JAKi in the management of ASUC.

METHODS

We performed a bibliographic search to identify studies focusing on the treatment of ASUC with JAKi.

RESULTS

Potential advantages of JAKi for the management of ASUC include their oral administration, rapid onset of action, short half-life, lack of immunogenicity, and effectiveness in patients with prior biologic exposure. Thirty studies (including 373 patients) have evaluated the efficacy of tofacitinib in ASUC, with a response rate (avoidance of colectomy) ranging between 43% and 100%, with a weighted mean of 82%. Experience with upadacitinib is more limited (only 10 studies and 74 patients are available) but also encouraging: mean colectomy-free rate ranging between 67% and 100%, with a weighted mean of 79%. However, experience with filgotinib in ASUC is currently nonexistent. Regarding safety, the available data does not reveal any new safety concerns when JAKi are used in ASUC, although follow-up periods are still short.

CONCLUSION

JAKi seems to be a promising treatment option for ASUC, with both tofacitinib and upadacitinib achieving colectomy-free rates of approximately 80%. Further studies are essential to define whether JAKi can replace cyclosporine/infliximab as second-line therapy for the medical management of ASUC, or whether they can even be used as initial treatment in place of intravenous corticosteroids.
