简要总结

This is a prospective observational study designed to understand how gut bacteria and body chemicals influence ulcerative colitis in the Indian population. Ulcerative colitis is a long term inflammatory disease of the colon that causes symptoms such as abdominal pain, diarrhea, and bleeding. The study will compare the gut microbiome and metabolite profiles of patients with ulcerative colitis and healthy individuals to identify specific bacterial and metabolic changes linked to the disease.

About 200 participants will be included, 100 with ulcerative colitis and 100 healthy controls matched for age and sex. Stool, blood, and biopsy samples will be collected for analysis. The study will also include a smaller follow up group of ulcerative colitis patients to observe changes over time. The samples will be processed using advanced genomic and metabolomic techniques to identify differences in gut microbes, metabolites, and genetic markers.

This research does not involve any new drug or device. Participants will continue their routine medical care as advised by their treating doctors. All data will be coded to maintain confidentiality. The information gained from this study may help in understanding disease mechanisms, identifying early biomarkers, and guiding the development of personalized or microbiome based treatment strategies for ulcerative colitis in the future.

结局指标

主要结局

Microbial diversity and richness (e.g., Shannon index, alpha-diversity, beta-diversity)

时间窗: At baseline, fecal, blood, and tissue samples from ulcerative colitis patients and healthy controls will be analyzed for gut microbial diversity, genetic mutations, and metabolite profiles. At 6 months, repeat samples from ulcerative colitis patients will assess temporal changes. At 12 months, follow up will evaluate stability or progression of dysbiosis and metabolomic changes.

Metabolomic profile differences between UC and healthy individuals.

Presence and frequency of genetic mutations correlated with gut dysbiosis.
