Ulcerative colitis: epidemiology, diagnosis, and management.

Area of Science:

• Gastroenterology
• Internal Medicine
• Inflammatory Bowel Disease

Background:

• Ulcerative colitis is a chronic idiopathic inflammatory bowel disease.
• Characterized by continuous mucosal inflammation starting in the rectum and extending proximally.
• Symptoms include bloody diarrhea, abdominal pain, urgency, and tenesmus; extraintestinal manifestations may occur.

Purpose of the Study:

• To outline the diagnostic approach to ulcerative colitis.
• To describe the therapeutic goals and step-up treatment strategies.
• To emphasize the role of primary care physicians in managing complications and preventive care.

Main Methods:

• Diagnosis relies on endoscopy revealing continuous colonic inflammation.
• Confirmatory biopsy specimens show signs of chronic colitis.
• Treatment is guided by symptom severity, employing a step-up approach.

Main Results:

• 5-Aminosalicylates are first-line for mild to moderate disease.
• Corticosteroids are used for moderate to severe disease, followed by steroid-sparing agents (thiopurines, anti-TNF agents, adhesion molecule inhibitors).
• Approximately 15% of patients require proctocolectomy despite medical therapies.

Conclusions:

• Treatment aims to induce and maintain remission, reduce complications, and improve quality of life.
• A step-up therapeutic approach is standard, tailored to disease severity.
• Primary care physicians are crucial for optimizing preventive care and mitigating risks associated with ulcerative colitis and its treatment.
