Insights
Crohn's disease may not be rare in India. High rates of intestinal tuberculosis might lead to under-recognition of Crohn's disease, impacting patient diagnosis and care.
Area of Science:
- Gastroenterology
- Internal Medicine
- Inflammatory Bowel Disease Research
Background:
- Crohn's disease (CD) is historically considered rare in India.
- This perception may stem from diagnostic challenges and potential under-recognition.
Purpose of the Study:
- To analyze patient data for Crohn's disease (CD) at a tertiary referral center.
- To assess the prevalence and characteristics of CD in an Indian population.
Main Methods:
- Retrospective analysis of chronic inflammatory bowel disease patients over 5 years.
- Diagnosis of CD based on clinical, histological, and exclusion criteria.
- Evaluation of disease presentation, involvement, and treatment response.
Main Results:
- 25 patients diagnosed with Crohn's disease (CD), mean age 31.7 years.
- Common symptoms included abdominal pain (84%) and diarrhea (80%).
- Ileocecal and colonic involvement were frequent; granulomas found in 48% of biopsies.
Conclusions:
- Crohn's disease (CD) may be more prevalent in India than previously thought.
- High prevalence of intestinal tuberculosis could lead to misdiagnosis or under-recognition of CD.
- Further research is needed to understand the true incidence and diagnostic challenges of CD 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.
