Summary

This study looks at whether a simple intestinal ultrasound can accurately measure disease activity in people with active ulcerative colitis, compared to the standard colonoscopy. Researchers will enroll 200 adults with active UC to see if the ultrasound scores match the colonoscopy findings. If successful, it could offer a less invasive way to monitor the disease.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

-Thorough medical history including abdominal pain, bloody diarrhea and its frequency, tensesmus,and mucous with stool, and physical examination (general and abdominal) stressing on fever, tachycardia, abdominal tenderness and significant weight loss. Each patient was phenotypically classified according to the Montreal classification (14). Harvey Bradshaw Index \[HBI\] (15) was used to assess clinical disease activity, where clinical remission was defined as HBI \< 5. * Colonoscopy will done and assessment of severity according to Mayo Endoscopic Score (MES) for ulcerative colitis. * Intestinal ultrasound examination: * Patient preparation: no specific preparation needed but fasting 6-8 hours before examination decrease gaseous content and allow better visualization. * Calculate ultrasound activity scores (including Ulcerative Colitis-Intestinal Ultrasound Index (UC-IUS index), Simple IUS score).
