Inflammatory Bowel Disease (IBD) Updates with Dr. Aline Charabaty

Understanding Inflammatory Bowel Disease (IBD)

• 💡 IBD is on the rise across all demographics, affecting individuals of all backgrounds, not just Caucasians or those of Jewish descent.
• 🩺 Early recognition of IBD symptoms, including extraintestinal manifestations, and prompt referral to specialists are crucial to prevent complications and hospitalizations.
• 🤝 Managing IBD requires a multidisciplinary approach involving internists, gastroenterologists, rheumatologists, surgeons, dietitians, and psychologists.

Diagnostic Approaches and Imaging

• 🩸 Blood in the stool, even if only on toilet paper, warrants serious evaluation due to rising colon cancer rates in young patients.
• 🔬 While IBS, lactose intolerance, or celiac disease might be initial thoughts, bleeding and anemia are concerning for IBD.
• 📊 Inflammatory markers like CRP and fecal calprotectin are important, though not always elevated in flares, and fecal calprotectin is more specific to gut inflammation.
• 📸 CT scans can show bowel wall thickening and inflammation, but intestinal ultrasound is a non-invasive, real-time tool for monitoring IBD, especially for Crohn's involving the terminal ileum.

Endoscopic and Pathological Findings

• 🔍 Endoscopic evaluation for suspected Crohn's disease reveals ulcerations, narrowing (strictures), and potentially skip lesions or patchy inflammation.
• 🔬 Ulcerative colitis typically presents with continuous inflammation, granular mucosa, and friability, always involving the rectum.
• 🧬 Pathological findings for IBD require both acute and chronic inflammatory changes, with granulomas being a supportive, though not definitive, sign of Crohn's disease.

Treatment Strategies and Goals

• 💊 Multiple drug classes are available, including anti-TNF agents, vedolizumab, IL-12/23 inhibitors, and small molecules (JAK inhibitors, S1PR modulators), chosen based on disease severity, location, phenotype, and patient factors.
• 🎯 Treatment goals have evolved beyond symptom relief to include clinical remission and endoscopic healing, which reduces the risk of flares, complications, and surgery.
• ⚖️ Shared decision-making with patients is key, considering their lifestyle, preferences, and goals of care, which extend beyond GI health to overall quality of life.

Diet, Lifestyle, and Preventive Health

• 🥗 While dietary recommendations vary, a healthy diet rich in fiber, fruits, and vegetables, and low in processed foods is generally advised, adapted to individual tolerance and cultural preferences.
• 💉 Patients with IBD on immunosuppressive therapy require age-appropriate vaccinations (except live virus vaccines) and annual skin checks due to increased risk of skin cancer.
• 🦴 Bone density scans are recommended for patients with a history of steroid use or other risk factors for osteopenia and osteoporosis.
• 🩸 Iron and B12 deficiencies are common, with IV iron often preferred for severe anemia or active inflammation due to impaired oral absorption.

Managing Flares and Extra-intestinal Manifestations

• 🚨 Acute severe ulcerative colitis requires hospitalization, prompt evaluation for infection (C. diff), IV steroids, fluids, and early surgical consultation.
• 🩹 Outpatient flares may be managed with oral prednisone while initiating advanced therapies, with IL-23 inhibitors or vedolizumab being common choices.
• 🏃 Extra-intestinal manifestations (EIMs), such as joint pain or uveitis, can influence therapy selection, with anti-TNF agents and JAK inhibitors often effective for these conditions.
