Is Crohn's disease rare in India?

BACKGROUND

Crohn's disease (CD) is believed to be rare in India.

OBJECTIVE

To analyze the data pertaining to patients with CD seen in a tertiary referral center.

METHODS

Data on patients with chronic inflammatory bowel disease attending our Unit over a 5-year period were analyzed. The diagnosis of CD was established by the presence of characteristic segmental bowel involvement, consistent histological picture, exclusion of infectious causes, relapsing nature of the disease, response to appropriate drug therapy, and lack of evidence for another etiological factor.

RESULTS

Of the 25 patients (age range 12-52, mean 31.7, years) 13 were men. Abdominal pain was present in 21 (84%) patients, diarrhea in 20 (80%), blood per rectum in 11 (44%) and fever in 4 (16%). The ileocecal region was involved in 6 (24%) patients and anal canal in 4 (16%); 19 (76%) had patchy involvement of different segments of the large bowel. Colonoscopic biopsies revealed granulomas in 12 (48%). During a mean follow up of 36.4 (range 6-54) months, 15 (60%) patients had 21 relapses. Despite initial response to 5-aminosalicylic acid in five patients, 23 needed glucocorticoid therapy at least once.

CONCLUSIONS

CD may not be rare in India. Because of the high prevalence of intestinal tuberculosis there is a possibility that CD may be under-recognized in India.
