Highlights
- Colitis encompasses various diseases, demanding a tailored, multidisciplinary approach for effective management and improved quality of life.
- Ulcerative colitis significantly impacts patients, with symptoms affecting both physical health and psychological well-being.
- Early diagnosis and innovative therapies are critical in navigating the complexities of colitis for better patient outcomes.
Summary and Overview
Colitis is inflammation of the colon’s mucosal lining, presenting as acute or chronic conditions such as infectious, ischemic, or autoimmune causes. Inflammatory bowel diseases (IBD) like ulcerative colitis and Crohn’s disease are prominent chronic forms, with symptoms including abdominal pain, diarrhea, urgency, tenesmus, and blood in stool. Diagnosis involves clinical evaluation, lab tests, imaging, and endoscopy with biopsy. Management is multidisciplinary, tailored to cause, and may include medication, lifestyle changes, and surgery for severe cases. Despite advances, challenges remain due to varied causes, symptom overlap, and potential complications like perforation and toxic megacolon.
Causes and Risk Factors
Colitis can result from infections (viral, bacterial, parasitic), ischemia, radiation, autoimmune disorders, or drug reactions. Infectious colitis often stems from contaminated food or Clostridium difficile infection. Ischemic colitis occurs due to reduced blood flow, commonly affecting older adults with cardiovascular issues. Autoimmune factors contribute to IBD, influenced by genetics and environment. Drug-induced and immune deficiency-related colitis also occur. Diet and stress may worsen symptoms, emphasizing the need for individualized diagnosis and treatment.
Symptoms and Pathophysiology
Common symptoms include abdominal pain, cramping, diarrhea (often bloody), tenesmus, and urgency. Extra-intestinal manifestations like arthritis, skin lesions, and eye inflammation affect up to 25% of ulcerative colitis patients. Severe complications include bowel perforation and fulminant colitis. Diarrhea in IBD results mainly from impaired absorption of sodium, chloride, and water due to inflammation disrupting ion transport. Symptoms reflect both local inflammation and systemic immune responses. Unlike IBS, colitis involves visible mucosal inflammation and immune-mediated damage.
Diagnosis and Differential Diagnosis
Diagnosis combines history, physical exam, blood and stool tests, imaging (CT, MRI), and endoscopy with biopsy, the latter being the gold standard. Differentiating ulcerative colitis from Crohn’s disease, infectious, ischemic, and radiation colitis is essential. IBS is distinguished by lack of inflammation and immune involvement. Emerging biomarkers like LGI2 and PRSS22 may improve early diagnosis and monitoring.
Disease Course and Complications
Ulcerative colitis features alternating flare-ups and remission, with symptom severity varying widely. Flare-ups involve increased inflammation and gastrointestinal symptoms, while remission may still involve silent disease progression. Complications from severe or chronic inflammation include bowel perforation, which can cause life-threatening infection requiring emergency surgery.
Patient Perspective
UC significantly affects quality of life, causing depression, anxiety, and sleep disturbances. Many patients feel the disease limits normal life, yet psychological support is often lacking in care. Symptom fluctuations and extra-intestinal manifestations add to the burden. Improved patient-physician communication and integration of emotional support are important for better outcomes.
Treatment and Management
Treatment aims to relieve symptoms during flare-ups and maintain remission, primarily through medications like budesonide, mesalamine, and bismuth subsalicylate. Severe cases may require hospitalization or surgery. Even during remission, continued medication adherence is crucial to prevent relapse. Lifestyle and dietary adjustments are recommended, though no specific diet has proven to alter disease development. Psychological interventions such as mindfulness may improve quality of life, while cognitive behavioral therapy shows limited impact on disease activity.
