Crohn's Disease Treatment: Current and Emerging Options

Crohn's Disease Treatment

There are several medication options available for treating the symptoms of Crohn's disease and inducing remission. The specific treatment will depend on factors like the location and severity of inflammation. Common medications include:

Aminosalicylates: Drugs like mesalamine and sulfasalazine are aminosalicylates. They work locally in the gut and are generally well-tolerated. Aminosalicylates are often the first line of treatment for mild to moderate cases of Crohn's located in the small intestine or beginning of the colon.

Corticosteroids: Corticosteroids like prednisone are powerful anti-inflammatory drugs that can provide quick symptom relief and induction of remission during active flares of Crohn's Disease Treatment. However, long-term use is not recommended due to side effects. Corticosteroids may be used for short periods to get symptoms under control before transitioning to a drug with fewer side effects.

Immunosuppressants: Immunomodulators and biologics are immunosuppressive medications that work to regulate the overactive immune response seen in Crohn's disease. Common options include azathioprine, 6-mercaptopurine, methotrexate, anti-TNF inhibitors, vedolizumab, and ustekinumab. Immunosuppressants are generally used for moderate to severe cases of Crohn's or when corticosteroids are not providing enough relief of symptoms. They help induce and maintain remission.

Antibiotics: Certain antibiotics like metronidazole and ciprofloxacin are sometimes used to specifically treat bowel inflammation caused by bacterial overgrowth in Crohn's. They can help control fistulas or perianal disease. Antibiotics are not a long-term treatment but may be needed intermittently during flare ups.

Nutritional Therapy for Crohn's Disease

Diet and nutrition play an important role in Crohn's disease treatment. Specific diets or nutrition supplements may be used alone or in addition to medications:

Exclusive Enteral Nutrition (EEN): EEN involves receiving complete nutrition through a liquid formula given through a feeding tube or orally, while excluding all regular food from the diet. This "rests" the gastrointestinal tract and provides powerful anti-inflammatory effects. EEN is especially beneficial for inducing remission in children with Crohn's.

Specialized Exclusion Diets: The specific carbohydrate diet, anti-inflammatory diet, and low FODMAP diet aim to eliminate problem foods that could trigger or exacerbate symptoms. Foods that may cause issues include high-fiber grains and raw fruits and vegetables, dairy, gluten, and foods high in poorly absorbed short-chain carbohydrates.

Nutritional Supplements: Supplements like probiotics, prebiotics, omega-3 fatty acids, vitamin D, zinc, and natural anti-inflammatories like turmeric may help support remission and control symptoms in some cases of Crohn's by improving gut health and modulating the immune system.

Surgery for Complications of Crohn's Disease

While medication and diet aim to control inflammation and maintain remission, surgery may sometimes be necessary to repair damage or treat dangerous complications from Crohn's such as:

Strictureplasty: This reconstructive procedure treats narrowing (strictures) in the bowels by cutting out the strictured segment and rejoining the healthy ends.

Resection surgery: When a segment of bowel is dangerously inflamed, damaged, or has developed an abscess or fistula, resection surgery may be required to remove the affected portion and rejoin the healthy ends.

Perianal surgery: Draining or seton placement treats abscesses and fistulas located in the perianal area near the anus. More advanced procedures may be needed for complex or recurrent perianal disease.

Colon cancer screening: Regular colonoscopies are advised for Crohn's patients beginning 8-10 years after diagnosis due to increased colon cancer risk from long-standing active inflammation. Any suspicious growths detected can be biopsied or removed during the procedure.

Ostomy surgery: In rare cases where the bowels need to fully rest and heal or in advanced disease, a temporary or permanent ostomy may be created by diverting feces to a surgically formed stoma on the abdomen.

Emerging Crohn's Disease Treatment

Research continues on new treatments to provide additional options for controlling Crohn's disease symptoms and inflammation when standard therapies are not effective enough. Some promising emerging treatments include:

JAK inhibitors: Drugs like upadacitinib that inhibit the JAK pathway of cytokine signaling show potential as novel biologic therapies for Crohn's, especially in moderate to severe cases resistant to TNF antagonists.

Stem cell therapy: Transplantation of carefully sourced and expanded mesenchymal stem cells aims to temper abnormal immune reactions and promote gut healing through their immunomodulating and regenerative properties.

Fecal microbiota transplantation: Transferring whole stool from a healthy donor into the recipient's gut via colonoscopy or enema may help reintroduce a balanced and healthy intestinal microbiota to treat complications from antibiotic-resistant C. difficile infection or inflammatory bowel disease like ulcerative colitis. Research on its role in Crohn's continues.

MT-1303: A first-in-class oral formulation of allogeneic human mesenchymal stem cells targets mucosal healing and treatment of fistulas in Crohn's with the goal of providing an alternative to injectable biologics. Phase 3 trials have shown promising results.

While more research is still needed, crohn's disease treatment emerging therapies represent promising new directions in developing optimized treatments that could greatly improve quality of life for the many people living with Crohn's disease worldwide. Controlling symptoms, eliminating complications, and achieving lasting remission continue to be important goals.
