Ulcerative colitis: diagnosis and treatment.

Area of Science:

• Gastroenterology
• Immunology
• Colorectal Surgery

Background:

• Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) with unknown etiology, characterized by recurrent symptoms and significant morbidity.
• Extraintestinal manifestations affect up to 25% of UC patients.
• Current diagnostic methods rely on endoscopy, with serological markers like perinuclear antineutrophilic cytoplasmic antibodies (pANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA) showing promise but not yet standard for routine use.

Purpose of the Study:

• To provide a comprehensive overview of ulcerative colitis diagnosis, treatment, and management.
• To highlight the importance of endoscopic diagnosis and risk stratification for colon cancer.
• To discuss current and emerging therapeutic strategies for ulcerative colitis.

Main Methods:

• Review of existing literature on ulcerative colitis etiology, diagnosis, and treatment modalities.
• Analysis of current clinical guidelines for managing ulcerative colitis.
• Discussion of the role of medical and surgical interventions, including novel therapies.

Main Results:

• Diagnosis is primarily endoscopic, with specific timelines for colon cancer screening based on disease extent.
• Treatment strategies are tailored to disease severity, utilizing 5-aminosalicylic acid (5-ASA) compounds, corticosteroids, and immunosuppressants like azathioprine or biologics such as infliximab.
• Surgery is reserved for medically refractory cases or complications like hemorrhage, perforation, or cancer.

Conclusions:

• Ulcerative colitis management requires a multi-faceted approach, balancing efficacy with the side effects of long-term therapies.
• Early and appropriate medical intervention is crucial, with surgical options available for refractory disease.
• Vigilant colon cancer surveillance is essential for patients with longstanding ulcerative colitis to mitigate cancer risk.
