When to Seek Medical Care for C. diff
If an individual has watery diarrhea, especially after administration of antibiotics or a recent hospitalization, C. difficile colitis should be suspected. Your physician should be notified in order to properly evaluate the diarrhea.
If the symptoms are severe, such as the presence of a high grade fever, severe diarrhea, moderate to severe abdominal pain, or signs of dehydration, hospitalization may be required for supportive care and treatment of the infection.
C. diff Diagnosis
Similar to other illnesses, a thorough medical examination by the doctor is necessary in evaluating for C. difficile colitis. A careful review of all medications, especially antibiotics, and recent hospitalization or nursing home admissions should be carried out.
Laboratory tests include blood work including a basic chemistry panel and complete blood count (CBC). An elevated white blood cell count (WBC), or leukocytosis, is very common in C. diff infection. The WBC is typically elevated in any type of bacterial infection, but in C. diff infection it is markedly elevated, often much higher than with other infections.
There are two ways to detect the presence of C. difficile.
Stool samples should be collected and analyzed. The presence of C. diff toxins in the stool is diagnostic of the infection, and the results of stool analysis are generally available within a day or so. The actual detection of Clostridium difficile bacterium by stool cultures may also be done. This, however, may take a few days, which may delay the diagnosis and treatment. C. diff culture may be positive in a carrier; however, the strain of the organism may be one that does not cause infection.
Other tests used to diagnose C. difficile colitis are a CT scan of the abdomen, which may show thickening of the wall of the colon, signifying inflammation. This finding is not specific as it may be present in other inflammatory diseases of the colon; however, it may add further evidence for C. difficile colitis in the proper clinical setting.
Sigmoidoscopy and colonoscopy are other procedures which may be useful in the evaluation of C. difficile colitis. These procedures involve inserting an endoscope (a tube), which has a camera and a light source at the tip, into the colon from the rectum. Visualization of pseudomembranes suggests C. diff infection. These tests are not always necessary to diagnose the infection, but they may have a role in cases where the diagnosis is in doubt due to non-diagnostic stool tests, unresponsiveness to appropriate treatment, or unusual presentation of the disease with little or no diarrhea and fever.
Examination of the stool for white blood cells (fecal leukocytes) is also an easy and helpful way to indicate possible C. diff infection.
C. diff Self-Care at Home
If C. diff infection is suspected, the doctor should be notified immediately. It is important to try to stay well hydrated by drinking adequate amounts of liquids in order to compensate for the fluid losses due to diarrhea. However, further management should be carried out under the supervision of a physician.
