Clostridium Difficile Infection
If you are having any symptoms or have any questions, please call 811 to speak with a registered nurse 24 hours a day.
What is Clostridium difficile?
Clostridium difficile (say: “klo-STRID-ee-um dif-uh-SEEL”), or C. diff., is a type of bacteria that lives in many people’s intestines. For these people, C. diff. is part of the normal balance of bacteria living in the intestines. It’s also present in the environment, such as in the soil, water and in animal feces.
Most people never experience any problems with C. diff. But if something throws off the balance in your intestines, C. diff. may begin to grow out of control. The bacteria start to release toxins that attack the lining of the intestines. This is what leads to symptoms of C. diff. infection.
What are the symptoms of C. diff. infection?
Typical symptoms of a mild C. diff. infection include:
- Frequent, watery diarrhea (3 or more times each day for several days)
- Abdominal pain or tenderness
Symptoms of a more severe C. diff. infection include:
- Frequent, watery diarrhea (up to 15 times each day)
- Severe abdominal pain or tenderness
- Loss of appetite
- Low-grade fever of up to 38.3°C (101°F) in children or 37.8°C to 38.9°C (100°F to 102°F ) in adults
- Blood or pus in the stool
When should I contact my healthcare provider?
Contact your healthcare provider if your symptoms begin after you started taking an antibiotic. Also call if you have symptoms that last longer than three days or get worse.
CAUSES & RISK FACTORS
Who is at risk for developing a C. diff. infection?
If you are in good health, you will probably not get a C. diff. infection. The most common risk factor for C. diff. is the use of antibiotic medicine. Antibiotics can disrupt the normal balance in the intestines.
Risk factors for C. diff. infection include:
- Antibiotic use, especially a type of antibiotic that is broad-spectrum (is able to treat a wide variety of bacteria) or if you have been taking antibiotics for an extended period of time
- Surgery of the gastrointestinal (GI) tract
- Abdominal surgery that requires moving the intestines aside
- Living in a nursing home or extended-care facility
- Colon problems, such as inflammatory bowel syndrome or colorectal cancer
- Weakened immune system
- Previous C. diff. infection
- Being 65 years of age or older
DIAGNOSIS & TESTS
How is C. diff. diagnosed?
Tests of stool samples can determine if you have C. diff. Sometimes, follow-up tests are needed to confirm the diagnosis.
In certain scenarios, your healthcare provider may do an X-ray or computerized tomography (CT) scan of your colon.
You may test positive for C. diff. without having any symptoms. This is known as C. diff. colonization. Some people are carriers for C. diff. but do not have C. diff. infection. A positive test result plus symptoms indicate that you have an active C. diff. infection.
How is C. diff. infection treated?
If you were taking an antibiotic when your symptoms started, your healthcare provider will probably ask you to stop taking it. You may be watched for dehydration if you have had bouts of severe diarrhea. About 25% of patients show improvement 2 to 3 days after they stop taking the antibiotic that was causing C. diff. infection.
For more serious cases, your healthcare provider may prescribe a 10-day dose of an antibiotic that has proved effective in treating C. diff. infection, such as metronidazole or vancomycin. You should improve after 72 hours of starting the medicine, although the diarrhea may return temporarily. In about 15% to 35% of cases, another round of antibiotics is needed.
Certain probiotics, or “good bacteria,” such as Saccharomyces boulardii, may be helpful against repeat C. diff. infection when taken along with the antibiotics your healthcare provider prescribes. Be sure to contact your healthcare provider before taking any supplements.
Home care includes:
- Drinking plenty of fluids to replace fluids your body has lost due to diarrhea
- Temporarily avoiding milk products and foods that contain wheat flour (your digestive tract may be very sensitive to them for a few days) and high-fibre foods (such as fruits, corn and wheat bran)
If you have diarrhea and think it could be caused by C. diff., contact your healthcare provider before using anti-diarrhea medicine. These drugs could make your infection worse.
What complications can C. diff. cause?
If the infection worsens, you may become dehydrated or be unable to pass your stool. Rarely, C. diff. infection can lead to sepsis (a serious infection that spreads through the blood) or a perforation (a hole) in the intestines.
How can I avoid getting C. diff.?
Since C. diff. spores (inactive bits of C. diff.) can live a long time on surfaces (such as toilet seats, telephones and doorknobs) you should use good hygiene to avoid the bacteria.
- Wash your hands often and thoroughly, using soap and water.
- Use disposable gloves when caring for someone who may have C. diff.
- Use chlorine bleach-based products to disinfect surfaces or items that may have come in contact with an infected person.
- Wash clothing that may be soiled with stool with detergent and chlorine bleach.
- If you are visiting someone in a healthcare facility, wash your hands before, during and after your visit, especially if you use the restroom facilities.
- Don’t use antibiotics unless your healthcare provider recommends them.
- If you have C. diff. infection, wash your hands with soap and water before eating and after using the restroom. Use a chlorine bleach-based product to clean surfaces you may have touched (doorknobs, telephones or keyboards, for example) to avoid spreading the infection to others.
