(Taehan Chang Yŏn'gu Hakhoe, 2019) Ooi, C.J.; Hilmi, I.; Banerjee, R.; Chuah, S.W.; Ng, S.C.; Wei, S.C.; Makharia, G.K.; Pisespongsa, P.; Chen, M.H.; Ran, Z.H.; Ye, B.D.; Park, D.I.; Ling, K.L.; Ong, D.; Ahuja, V.; Goh, K.L.; Sollano, J.; K.Lim, W.C.; Leung, W.; Raja Ali, R.A.; Wu, D.C.; Ong, E.; Mustaffa, N.; Limsrivilai, J.; Hisamatsu, T.; Yang, S.K.; Ouyang, Q.; Geary, R.; de Silva, H.J.; Rerknimitr, R.; Simadibrata, M.; Abdullah, M.; Leong, R.W.L.; Asia Pacific Association of Gastroenterology (APAGE) Working Group on Inflammatory Bowel Disease and Asian Organization for Crohn's and Colitis
ABSTRACT: The Asia-Pacific Working Group on inflammatory bowel disease (IBD) was established in Cebu, Philippines, under the auspices of the Asian Pacific Association of Gastroenterology with the goal of improving IBD care in Asia. This consensus is carried out in collaboration with Asian Organization for Crohn's and Colitis. With biologic agents and biosimilars becoming more established, it is necessary to conduct a review on existing literature and establish a consensus on when and how to introduce biologic agents and biosimilars in the conjunction with conventional treatments for ulcerative colitis (UC) and Crohn's disease (CD) in Asia. These statements also address how pharmacogenetics influence the treatments of UC and CD and provide guidance on response monitoring and strategies to restore loss of response. Finally, the review includes statements on how to manage treatment alongside possible hepatitis B and tuberculosis infections, both common in Asia. These statements have been prepared and voted upon by members of IBD workgroup employing the modified Delphi process. These statements do not intend to be all-encompassing and future revisions are likely as new data continue to emerge.

Incidence and phenotype of inflammatory bowel disease based on results from the Asia-pacific Crohn's and colitis epidemiology study
(Elsevier-W.B. Saunders, 2013) Ng, S.C.; Tang, W.; Ching, J.Y.; Wong, M.; Chow, C.M.; Hui, A.J.; Wong, T.C.; Leung, V.K.; Tsang, S.W.; Yu, H.H.; Li, M.F.; Ng, K.K.; Kamm, M.A.; Studd, C.; Bell, S.; Leong, R.; de Silva, H.J.; Kasturiratne, A.; Mufeena, M.N.; Ling, K.L.; Ooi, C.J.; Tan, P.S.; Ong, D.; Goh, K.L.; Hilmi, I.; Pisespongsa, P.; Manatsathit, S.; Rerknimitr, R.; Aniwan, S.; Wang, Y.F.; Ouyang, Q.; Zeng, Z.; Zhu, Z.; Chen, M.H.; Hu, P.J.; Wu, K.; Wang, X.; Simadibrata, M.; Abdullah, M.; Wu, J.C.; Sung, J.J.; Chan, F.K.; Asia-Pacific Crohn's and Colitis Epidemiologic Study (ACCESS) Study Group
BACKGROUND & AIMS: Inflammatory bowel diseases (IBD) are becoming more common in Asia, but epidemiologic data are lacking. The Asia Pacific Crohn's and Colitis Epidemiology Study aimed to determine the incidence and phenotype of IBD in 8 countries across Asia and in Australia. METHODS: We performed a prospective, population-based study of IBD incidence in predefined catchment areas, collecting data for 1 year, starting on April 1, 2011. New cases were ascertained from multiple overlapping sources and entered into a Web-based database. Cases were confirmed using standard criteria. Local endoscopy, pathology, and pharmacy records were searched to ensure completeness of case capture. RESULTS: We identified 419 new cases of IBD (232 of ulcerative colitis [UC], 166 of Crohn's disease [CD], and 21 IBD-undetermined). The crude annual overall incidence values per 100,000 individuals were 1.37 for IBD in Asia (95% confidence interval: 1.25-1.51; 0.76 for UC, 0.54 for CD, and 0.07 for IBD-undetermined) and 23.67 in Australia (95% confidence interval: 18.46-29.85; 7.33 for UC, 14.00 for CD, and 2.33 for IBD-undetermined). China had the highest incidence of IBD in Asia (3.44 per 100,000 individuals). The ratios of UC to CD were 2.0 in Asia and 0.5 in Australia. Median time from symptom onset to diagnosis was 5.5 months (interquartile range, 1.4-15 months). Complicated CD (stricturing, penetrating, or perianal disease) was more common in Asia than Australia (52% vs 24%; P = .001), and a family history of IBD was less common in Asia (3% vs 17%; P < .001). CONCLUSIONS: We performed a large-scale population-based study and found that although the incidence of IBD varies throughout Asia, it is still lower than in the West. IBD can be as severe or more severe in Asia than in the West. The emergence of IBD in Asia will result in the need for specific health care resources, and offers a unique opportunity to study etiologic factors in developing nations.
Primary care management of chronic constipation in Asia: the ANMA chronic constipation tool
(The Korean Society of Neurogastroenterology and Motility, 2013) Gwee, K.A.; Ghoshal, U.C.; Gonlachanvit, S.; Chua, A.S.; Myung, S.J.; Rajindrajith, S.; Patcharatrakul, T.; Choi, M.G.; Wu, J.C.; Chen, M.H.; Gong, X.R.; Lu, C.L.; Chen, C.L.; Pratap, N.; Abraham, P.; Hou, X.H.; Ke, M.; Ricaforte-Campos, J.D.; Syam, A.F.; Abdullah, M.
Chronic constipation (CC) may impact on quality of life. There is substantial patient dissatisfaction; possible reasons are failure to recognize underlying constipation, inappropriate dietary advice and inadequate treatment. The aim of these practical guidelines intended for primary care physicians, and which are based on Asian perspectives, is to provide an approach to CC that is relevant to the existing health-care infrastructure. Physicians should not rely on infrequent bowel movements to diagnose CC as many patients have one or more bowel movement a day. More commonly, patients present with hard stool, straining, incomplete feeling, bloating and other dyspeptic symptoms. Physicians should consider CC in these situations and when patients are found to use laxative containing supplements. In the absence of alarm features physicians may start with a 2-4 week therapeutic trial of available pharmacological agents including osmotic, stimulant and enterokinetic agents. Where safe to do so, physicians should consider regular (as opposed to on demand dosing), combination treatment and continuous treatment for at least 4 weeks. If patients do not achieve satisfactory response, they should be referred to tertiary centers for physiological evaluation of colonic transit and pelvic floor function. Surgical referral is a last resort, which should be considered only after a thorough physiological and psychological evaluation. © The Korean Society of Neurogastroenterology and Motility.
