[Prognostic factors of ulcer colitis flow]

Area of Science:

• Genetics
• Immunology
• Gastroenterology

Context:

• Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
• Understanding prognostic factors is crucial for optimizing patient management.
• Genetic polymorphisms may influence UC phenotype and treatment response.

Purpose:

• To investigate the association between specific gene polymorphisms and the clinical phenotype of ulcerative colitis.
• To identify prognostic factors for disease severity and the need for systemic immunosuppressive therapy.

Summary:

• This study analyzed 101 ulcerative colitis patients, examining gene polymorphisms (IL-12b, IL-17A, IL-17F, TNF-alpha) and their relation to disease phenotype within the first 5 years.
• IL-17 F T7488C and TNF-alpha G-308A polymorphisms were found to be significantly associated with disease severity, inflammatory polyp formation, and the need for immunosuppressive therapy.
• No significant influence of IL-12b A1188C and IL-17A G-197A polymorphisms on the UC phenotype was identified.

Impact:

• Identified key genetic markers (IL-17 F T7488C, TNF-alpha G-308A) that predict ulcerative colitis progression and therapeutic requirements.
• Developed a prognostic algorithm for patient supervision, enabling tailored treatment strategies.
• Contributes to personalized medicine approaches in managing ulcerative colitis.
