About Pouchitis
The root causes of pouchitis are not fully understood, but several factors have been found:
- Dysbiosis: Changes in the balance of bacteria in the gut, like having too much or too little of certain types, may play a role in the development of pouchitis.
- Altered fecal microbes: Changes in the bacteria found in stool before surgery have also been linked with pouchitis.
Non-modifiable risk factors for pouchitis cannot be changed or controlled. These include:
- History of ulcerative colitis: This increases your chance of developing pouchitis after colon removal surgery.
- Severe disease at the time of colectomy: A more serious condition at the time of surgery raises the risk of pouchitis.
- Other health issues: Other issues like joint pain or eye problems may suggest immune system issues, which can increase the risk of developing pouchitis by causing more inflammation.
- Younger age at the time of surgery: Having surgery at a younger age means a higher chance of developing pouchitis over time
- Immune disorders: Other immune system problems raise the risk of pouchitis
Modifiable risk factors for pouchitis can be influenced or changed. These include:
- Use of biologics and steroids before colectomy: These medicines affect the immune system and may increase the risk of pouchitis after surgery.
- Postoperative use of nonsteroidal anti-inflammatory drugs (NSAIDs): These medicines can irritate the digestive system and increase the risk of inflammation in the pouch.
- Smoking: Smoking can damage the tissues and worsen inflammation, increasing the risk of pouchitis.
- Poor diet: A diet low in nutrients or high in irritating foods can negatively impact gut health and add to the development of pouchitis.
It's important to note that these risk factors are based on studies and may be different for each person. It's always best to talk with a healthcare professional for personalized advice.
The most common early symptoms of pouchitis include:
- Watery diarrhea
- Abdominal pain
- Fever
- Skin irritation around the anus
As pouchitis progresses or becomes more severe, other common symptoms that may occur include:
- Loss of control over bowel movements (incontinence)
- Problems in other parts of the body, like joint pain or eye issues
- Severe constipation (obstipation)
- Swelling or bloating of the abdomen (abdominal distention)
- Vomiting
It's important to note that these symptoms are not specific to pouchitis and may be caused by other conditions too. To confirm the diagnosis and rule out other conditions, specific tests using a scope (endoscope)and looking at tissue samples (histology) are needed. If you have any of these symptoms, it is important to talk with your healthcare professional for the right diagnosis and treatment.
To diagnose pouchitis, the following exams, tests, and procedures are commonly performed:
- History and physical exam: Healthcare providers will ask about your symptoms, like how often you go to the bathroom, if you have any pain, and other things that could affect your condition. They will also check your abdomen for tenderness, bloating, or swelling.
- Lab tests: Blood tests may be done to check for inflammation by measuring markers like C-reactive protein (CRP). Stool tests may also measure fecal calprotectin to help check for inflammation in the digestive system.
- Pouchoscopy: This test is done by inserting a thin, flexible tube with a camera into the anus to check the pouch for any problems. It allows doctors to see the inside of the pouch and look for signs of inflammation or other issues.
- Biopsy: During endoscopy, small tissue samples may be taken from the pouch to look at under a microscope. This helps confirm the diagnosis, rule out otherconditions and check how much inflammation is present.
To determine the stage or severity of pouchitis, additional exams, tests, and procedures may include:
- Modified pouchitis disease activity index (mPDAI) score: This scoring system measures symptoms such as diarrhea, abdominal pain, fever, and the urgent need to use the bathroom. It helps determine how active the disease is.
It's important to note that these exams and tests should be performed by healthcare professionals. They will help give an accurate diagnosis and determine the severity of the pouchitis.
The goals of treatment for pouchitis are to control the disease, prevent it from coming back, and reduce symptoms. Here are the different treatment options and how they work to reach these goals:
- Medication types: Antibiotics are the main treatment for helping control pouchitis. They help reduce inflammation and control overgrowth of bacteria in the pouch.
- Therapies: Probiotics have been helpful in keeping pouchitis under control after antibiotics. They help restore a healthy balance of bacteria in the pouch, reducing inflammation and preventing the condition from coming back.
- Therapeutic procedures: Fecal microbiota transplant (FMT) is a new approach for treating pouchitis. It involves transferring healthy bacteria from a donor's stool into the patient's colon. This helps restore a healthy balance of bacteria and reduce inflammation.
- Health behavior changes: Dietary interventions can help manage pouchitis. Eating fruits and vegetables, which are rich in fiber and nutrients, may support a healthy balance of gut bacteria and reduce inflammation. It’s recommended to include these foods in your daily diet.
Overall, these treatments aim to restore balance to the bacteria in the pouch, reduce inflammation, and prevent pouchitis from coming back. However, it's important to talk with your healthcare professional before making any changes or starting any new treatments.
Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Other side effects can occur. Check with your health care professional or read the information provided with your medication for additional side effect information.
