ABSTRACT
BACKGROUND: Ustekinumab (UST) and vedolizumab (VDZ) are biologic therapies for moderate-to-severe Crohn's disease (CD) in patients who failed or had contraindication to anti-TNF treatment. AIMS: To evaluate ustekinumab efficacy as third-line treatment after swapping from VDZ for failure. METHODS: We conducted a monocentric, retrospective, observational study where CD patients were followed for 12 months from the beginning of UST therapy. We assessed clinical activity (HBI) and laboratory markers (CRP) at the initiation of UST therapy (T0) and after 2(T2), 6(T6) and 12(T12) months. Endoscopic activity was recorded at T0 and T12. We registered data regarding their clinical history and previous biologic treatments. Steroid-free clinical remission was defined as HBI ≤ 4 without need for steroids. Clinical response was defined as HBI reduction of at least three points or the suspension of steroids. RESULTS: 27 CD patients treated with UST after VDZ failure had a minimum follow up of 12 months and were included. All patients had previously been treated with anti-TNF agents. After 12 months, steroid-free clinical remission was evident in 15 (55.5%) patients, 5 (18.5%) had clinical response, while 7 (26%) had suspended for failure or persisted on treatment after optimization. CONCLUSIONS: Ustekinumab should be considered as third-line biologic treatment in multi-refractory CD patients.
ABSTRACT
BACKGROUND: COVID-19 pandemic is an unprecedented global medical emergency. National and international gastrointestinal societies recommended that any endoscopic activity during the lockdown phase of the pandemic should be limited to emergency or non-deferrable procedures only. We assessed the financial implications and impact on endoscopy activity of the lockdown phase in a tertiary referral endoscopy unit. METHODS: The number of endoscopy procedures canceled and performed in our endoscopy unit during our "delay phase" (16-22/03/2020) and "lockdown phase" (23/03-29/05/2020) was reviewed and compared with endoscopy activity conducted during the same period in 2019. The financial impact was subsequently analyzed. RESULTS: Between 16/03/2020 and 29/05/2020, 683 procedures were canceled and 365 non-deferrable procedures were performed. In contrast, in 2019, 3437 procedures were performed over the same timeframe, resulting in a revenue contraction of approximately 2,062,857. We estimated that the number of lists required to recuperate the canceled endoscopic activity, ranges from 103-155, depending on the level of personal protective equipment required and mitigating policy relating to COVID-19. CONCLUSION: Our results highlight that COVID-19 pandemic had a substantial negative impact on our endoscopy activity and on the revenue generated by our endoscopy unit.
