The aim of this report is to provide details of the methodology and results of the Sri Lankan component of the Asia-Pacific Crohn's and Colitis. Epidemiology Study. Fourteen state and private hospitals with specialist services in the Gampaha and Colombo districts were kept under surveillance over a 12 month period to recruit patients with newly diagnosed Inflammatory Bowel Disease (IBD) who were permanent residents of the Gampaha district. Thirty five cases (ulcerative colitis-21, Crohn's disease-13, IBD-undetermined-1) were detected, giving a crude annual IBD incidence of 1.59 per 100,000 population.

OBJECTIVE: Health-related quality of life (QOL) is an important outcome measure in inflammatory bowel disease (IBD). QOL of Asian patients with IBD at presentation has not been studied. AIM: This study evaluates the QOL of IBD patients at diagnosis from an inception cohort across eight countries in Asia. METHODS: Health-related QOL was measured by the validated IBD Questionnaire (IBDQ) in patients with newly diagnosed IBD between 2011 and 2012. Disease activity was assessed by the Simple Clinical Colitis Activity Index and Harvey-Bradshaw index for ulcerative colitis (UC) and Crohn’s disease (CD), respectively. Demographic and disease characteristics were recorded. RESULTS: 284 incident IBD cases (CD 93; UC 147; IC 14) were included. Median age was 37 (IQR: 26–49). Median duration from symptom onset to diagnosis was 6 months (IQR:2– 24). Overall mean IBDQ score was 159 ± SEM 2.2 (Remission: IBQ≥170). The median IBDQ Score of South Asians (Thailand, Malaysia, Indonesia, Sri Lanka) (150; IQR:117–181) was significantly lower than the Han Chinese (Mainland China, Hong Kong, Singapore, Macau) (167; IQR:139–190; p = 0.003). IBD patients with active disease had significantly lower scores for all 4 dimensions of IBDQ (bowel, systemic, emotional and social functions) compared with those in remission (p < 0.001). Multiple regression analyses identified only disease activity index to be associated with variations in QOL (p < 0.001). There was no significant difference in QOL between patients with CD, UC or IC (p = 0.403). QOLwas not significantly affected by disease behavior for CD (B1, B2, B3, or perianal) but worsened with increasing mucosal involvement in UC (extensive > distal > proctitis; p = 0.014). QOL score was not affected by employment status, education level or smoking history. CONCLUSION: QOL is impaired in newly diagnosed IBD patients, and varies across ethnic groups in Asia. Active disease and more extensive disease are associated with worse QOL in IBD.
Survival of patients with alcoholic and cryptogenic cirrhosis without liver transplantation: a single center retrospective study
(Biomed Central, 2012) Senanayake, S.M.; Niriella, M.A.; Weerasinghe, S.K.; Kasturiratne, A.; de Alwis, J.P.N.; de Silva, A.P.; Dassanayake, A.S.; de Silva, H.J.
BACKGROUND: There is no recent data addressing the long term survival of cirrhosis patients without transplantation, but with the availability of optimal pharmacological and endoscopic therapies. We compared the long term transplant free survival of alcoholic (AC) and cryptogenic (CC) cirrhosis patients in a setting where liver transplantation was, until very recently, not available. AC and CC patient details were extracted from our database, maintained since 1995. For those who had not attended clinics within the past 4 weeks, the patient or families were contacted to obtain survival status. If deceased, cause of death was ascertained from death certificates and patient records. Survival was compared using Kaplan-Meier curves. RESULTS: Complete details were available in 549/651 (84.3%) patients (AC 306, CC 243). Mean follow up duration (SD) (months) was 29.9 (32.6). 82/96 deaths (85.4%) among AC and 80/94 deaths (85.1%) among CC were liver related. Multivariate analysis showed age at diagnosis and Child's class predicted overall survival among all groups. The median survival in Child's class B and C were 53.5 and 25.3 months respectively. Survival was similar among AC and CC. Among AC survival was improved by abstinence [HR = 0.63 (95% CI: 0.40-1.00)] and was worse with diabetes [HR=1.59 (95% CI: 1.02- 2.48)] irrespective of alcohol status. CONCLUSIONS: The overall survival of AC was similar to CC. Death in both groups were predominantly liver related, and was predicated by age at diagnosis and Child class. Among AC, presence of diabetes and non-abstinence from alcohol were independent predictors for poor survival.
