Abstract
BACKGROUND Therapeutic management of inflammatory bowel diseases (IBD) is rapidly evolving, with an expanding armoury of biological drugs at our disposal. However, real-world findings about treatment persistence and the impact of biologicals on surgery remain inconsistent. AIMS This study aimed to investigate trends in biological use and surgery rates in a nationwide cohort of biological-naïve IBD patients. METHODS Patients with IBD who initiated biological treatment between 2011 and 2018 were identified in the Danish National Patient Registry. Data on use of biologicals, surgeries and healthcare costs were retrieved and analysed for time trends. RESULTS Between 2011 and 2018, a total of 6,036 IBD (51% ulcerative colitis (UC), 49% Crohn's disease (CD)) patients received biological treatment for the first time. Cumulative use of biologicals increased from 5.0% to 10.8% among UC and 8.9%-14.5% among CD patients. Infliximab remained the most-prescribed first-line biological for UC and CD. Treatment persistence was 44.3% and 16.9% after 1 and 3 years in UC, compared to 59.9% and 33.6% in CD patients. Overall, 32.8% of patients switched to a second biological. Surgery rates decreased in both UC (P = 0.015) and CD (P = 0.008) patients and remained significant for UC in the Cox regression model (P = 0.002). Outpatient and surgical costs also fell among both UC and CD patients. CONCLUSIONS Persistence rates for first-line biologicals among IBD patients were low and one-third switched treatment. Surgery rates and direct costs decreased over time, but whether this is related to the use of biologicals has yet to be determined.

Gut Liver 2021; 15:867-877. [PMID: 33785664 PMCID: PMC8593500 DOI: 10.5009/gnl20353] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 01/02/2021] [Accepted: 01/08/2021] [Indexed: 11/22/2022] Open
Abstract
Background/Aims Although anti-tumor necrosis factor (TNF) agents have been widely used to treat ulcerative colitis (UC), the real-world incidence of suboptimal response to anti-TNF agents has not been thoroughly investigated, especially among Asians. Methods Using the Korean National Health Insurance database, we collected data on UC patients who initiated anti-TNF agents between July 1, 2014, and June 30, 2017. We assessed suboptimal responses, including anti-TNF discontinuation or dose escalation, switching to other biologics, augmentation with a non-biologic therapy, and the requirement for colectomy. Results A total of 1,268 patients were included as new anti-TNF users (infliximab 713, adalimumab 433, golimumab 122). The proportion of patients who experienced at least one suboptimal response within 1 year among all patients was 63.5%, including 59.1%, 69.5%, and 68.0% of patients treated with infliximab, adalimumab, and golimumab, respectively. The cumulative incidences of at least one suboptimal response over time were 41.5%, 63.7%, 80.5%, and 87.1% at 6, 12, 24, and 36 months, respectively. Cox proportional hazards modeling revealed that adalimumab was associated with a higher risk of at least one suboptimal response (hazard ratio [HR], 1.29; 95% confidence interval [CI], 1.13 to 1.48), dose escalation (HR, 4.35; 95% CI, 2.97 to 6.38) and discontinuation (HR, 1.25; 95% CI, 1.03 to 1.52) than infliximab. Golimumab was associated with a higher risk of switching to other biologics than infliximab (HR, 1.78; 95% CI, 1.21 to 2.60). Conclusions More than half of Korean UC patients had suboptimal responses to anti-TNF agents within 1 year. UC patients treated with infliximab might be less prone to suboptimal responses than those treated with adalimumab or golimumab.

Abstract
INTRODUCTION Ulcerative colitis (UC) is an idiopathic, chronic inflammatory disease of the colon, characterized by relapsing and remitting symptoms. Although traditionally viewed as a Western disease, the incidence and prevalence of UC is increasing in developing regions, including Asian countries. AREAS COVERED A PubMed search identified articles describing epidemiology, disease burden, patient demographics, clinical characteristics, risk factors, and treatment of UC across Asia. We review the epidemiology and disease course of UC across Asia, including region-specific factors that may aid development of more cost-effective treatment approaches tailored to the needs of Asian populations. EXPERT OPINION The opinion of non-Pfizer-affiliated practicing gastroenterologists is that epidemiological data from the last four decades have shown 1.5-fold to almost 20-fold increases in the incidence and prevalence of UC in some Asian countries, although prevalence remains generally lower than in the West. As the prevalence of UC rises, so will overall healthcare costs. Disparities in healthcare systems and funding mean that different Asian countries face unique challenges in how best to use available resources, including selection from a growing number of emerging treatment options. More clinical trial and real-world data are required to help define treatment approaches that will most benefit Asian populations.

Effect of Thiopurine on Potential Surgical Intervention in Crohn’s Disease in Korea: Results from the CONNECT Study. J Clin Med 2020; 10:jcm10010025. [PMID: 33374886 PMCID: PMC7796432 DOI: 10.3390/jcm10010025] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2020] [Revised: 12/09/2020] [Accepted: 12/16/2020] [Indexed: 12/21/2022] Open
Abstract
Objectives: The incidence of Crohn's disease and the number of associated surgeries are increasing in Korea. This study investigated the effect of azathioprine/6-mercaptopurine (6-MP) and TNF-α antagonists on abdominal and perianal surgery in Korean patients with Crohn's disease. Design: A retrospective cohort study. Setting: Data from the Crohn's Disease Clinical Network and Cohort (CONNECT) were used. Patients with confirmed Crohn's disease between 1982 and 2008 from 32 hospitals in the Republic of Korea were enrolled. The effect of azathioprine/6-MP on abdominal and perianal surgery was analysed using logistic regression analysis adjusting for age and sex. Participants: In total, 1161 Crohn's disease patients were included in the Republic of Korea in the surgery (n = 462, male = 339, female = 123) and control groups (n = 699, male = 484, female = 215). Results: In total, 1161 patients were selected, with 462 patients who underwent abdominal (n = 245) or perianal surgery (n = 217). The preoperative usage rates of azathioprine/6-MP were 18.8% and 65.1% (p < 0.0001) in the surgery and control groups, respectively. The preoperative usage rates of TNF-α antagonists were 7.1% and 23.3% (p < 0.0001) in the surgery and control groups, respectively. A multivariate analysis revealed that the preoperative use of azathioprine/6-MP had an odds ratio of 0.094 for all surgeries (95% confidence interval [CI]: 0.070-0.127, p < 0.0001), 0.131 for abdominal surgery (95% CI: 397-1.599, p < 0.0001), and 0.059 for perianal surgery (95% CI: 0.038-0.091, p < 0.0001). The preoperative use of TNF-α antagonists had an odds ratio of 0.225 for all surgeries (95% CI: 0.151-0.335, p < 0.0001), 0.403 for abdominal surgery (95% CI: 0.261-0.623, p < 0.0001), and 0.064 for perianal surgery (95% CI: 0.026-0.160, p < 0.001). Strengths of this study: The study presents new evidence of the reduced risk of surgery following azathioprine use in Crohn's disease patients. Limitations of this study (1) This was not a controlled prospective study. (2) There was a selection bias specific to the CONNECT cohort. (3) The combination or sequential use of azathioprine/6-MP and TNF-α antagonists was not excluded. Conclusion: Azathioprine/6-MP is significantly associated with a reduced risk of abdominal and perianal surgery in Korean patients with Crohn's disease.

Incidence of suboptimal response to tumor necrosis factor antagonist therapy in inflammatory bowel disease in newly industrialised countries: The EXPLORE study. Dig Liver Dis 2020; 52:869-877. [PMID: 32563721 DOI: 10.1016/j.dld.2020.05.031] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2020] [Revised: 05/11/2020] [Accepted: 05/18/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Incidence of inflammatory bowel disease (IBD) is increasing in newly industrialised countries (NICs); however, data on suboptimal response to anti-tumor necrosis factor (anti-TNF) agents are limited. OBJECTIVES To assess incidence and indicators of suboptimal response to first anti-TNF therapy in IBD patients in NICs. METHODS A chart review was conducted in ten countries from Asia-Pacific (APAC), Latin America (LatAm), and Russia and the Middle East (RME) regions among patients diagnosed with ulcerative colitis (UC) or Crohn's disease (CD), initiating anti-TNF therapy in 2010-2015. The cumulative incidence of suboptimal response to anti-TNF therapy was assessed using the following indicators: dose escalation or discontinuation, augmentation with non-biologic therapy, IBD-related hospitalization, or surgery. RESULTS The study included 1,674 patients (570 UC; 1,104 CD). At 24 months, 32.9% of UC (APAC: 45.1%; LatAm: 38.2%; RME: 23.8%) and 41.2% of CD patients (APAC: 54.1%; LatAm: 42.5%; RME: 29.5%) had experienced suboptimal response. The most frequent first indicator was non-biologic therapy augmentation in LatAm (41.7%), IBD-related hospitalization in RME (UC: 50.7%; CD:37.3%) and in APAC for CD (39.1%), and anti-TNF discontinuation in APAC for UC (38.3%). CONCLUSION Suboptimal response to anti-TNF agents is common in IBD patients in NICs. Observed regional differences in the incidence and indicators may reflect local practice and anti-TNF restrictions in IBD management. NCT REGISTRATION NUMBER NCT03090139.
