Background
Inflammatory bowel disease (IBD) is considered uncommon in Asia. The aim of this study was to document the demographic characteristics and clinical aspects of ulcerative colitis (UC) and Crohn’s disease (CD) in Kerala, India.
Methods
A survey of IBD in Kerala was performed. All gastroenterologists in the region were invited. From May 2013 to October 2015, data were collected in a standardized pro-forma.
Results
Forty-seven doctors in 34 centers contributed data. A total of 2142 patients were analyzed. This is the largest state-wide survey of IBD in India. Ulcerative colitis was diagnosed in 1112 (38 new), Crohn’s disease in 980 (53 new), and 50 were unclassified (5 new). The district-wise distribution of IBD cases correlated with the District-wise Gross State Domestic Product (r = 0.69, p < 0.01). Three percent was below the age of 18. Patients with UC had more diarrhea (73% vs. 51%), bleeding PR (79% vs. 34%), and intermittent flares (35% vs. 13%) (all p < 0.01). Patients with CD had more abdominal pain (62% vs. 46%), weight loss (53% vs. 40%), fever (28% vs. 18%), and history of antituberculosis treatment (21% vs. 5%) (all p < 0.01). Compared to adults, children (below 18 years) were more likely to have extensive UC (58% vs. 34%, p < 0.01) and unclassified IBD (15% vs. 2%, p < 0.01).
Conclusion
Inflammatory bowel disease is common in Kerala, India. The disease characteristics of patients with IBD are almost similar to those from other parts of the country. Both UC and CD were seen in equal proportion in Kerala.
