Prognostic factors in Crohn's disease: a systematic review
Key prognostic factors for Crohn's disease include immunosuppressive therapy, intestinal resection, and disabling disease. Ileal involvement, perianal disease, and corticosteroid treatment are significant predictors.
Area of Science:
- Gastroenterology
- Immunology
Background:
- Crohn's disease natural history is influenced by various prognostic factors.
- Identifying these factors is crucial for patient management.
Purpose of the Study:
- To systematically review and identify the most significant prognostic factors in Crohn's disease.
Main Methods:
- Systematic literature review.
Main Results:
- Key indicators for Crohn's disease progression include need for immunosuppressive therapy, intestinal resection, and disabling disease.
- Ileal involvement, perianal disease, and initial corticosteroid treatment are significant prognostic markers.
- Factors like young age, CRP levels, and smoking status showed inconsistent associations across studies; anti-TNF drugs suggest a protective role needing further confirmation.
Conclusions:
- A "top-down" treatment strategy may be suitable for a specific subgroup of Crohn's disease patients identified with these prognostic markers.

Inflammatory Bowel Disease III: Crohn's Disease
Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
