Pseudomembranous Colitis Caused By Antibiotics

What Causes Pseudomembranous Colitis

Clostridium Difficile Infection (Pseudomembranous Colitis)

For some people, C. diff is part of the normal bacterial flora, or the collection of bacteria, in the gastrointestinal tract. Pseudomembranous colitis results from changes to the bacterial flora after you use antibiotics.

In some cases, taking antibiotics can cause C. diff to grow out of control and release toxins into intestinal tissues. These toxins attack the lining of the intestine and cause pseudomembranous colitis symptoms.

Can Antibiotics Cause Pseudomembranous Colitis

While almost any antibiotic can cause pseudomembranous colitis, some antibiotics are more commonly linked to pseudomembranous colitis than others, including: Fluoroquinolones, such as ciprofloxacin and levofloxacin. Penicillins, such as amoxicillin and ampicillin. Clindamycin

How long does it take to recover from pseudomembranous colitis?

Most patients75% of symptomatic patients and 25% of patients with colitiswill experience complete recovery within 10 days.

Antibiotics May Cause Issues Such As Pseudomembranous Colitis: Part One

In order to treat our bodies of bacterial infections, we take antibiotics. Many people are against the use of antibiotics and vaccines in hopes of leaving a natural, clean life. Antibiotics do far more good than they do harm in many cases, but antibiotics can leave lasting affects on the bodys digestive system.


Pseudomembranous colitis is often referred to as the antibiotic- associated colitis. It is also called C. difficile colitis. Pseudomembranous colitis is inflammation of the colon and is associated with an overgrowth of the bacterium Clostridium difficile, C diff for short. The overgrowth of Clostridium difficile is most often related to recent antibiotic use.

How antibiotics cause pseudomembranous colitis:

Normally, the body will naturally keep the bacteria in the colon in a healthy balance. Antibiotics and other medications can upset and throw off the balance though. Pseudomembranous colitis takes place when the Clostridium difficile bacteria quickly outgrows other bacteria that would normally keep them in check and balanced. Specific toxins produced by Clostridium difficile are usually only seen in tiny amounts. But they can rise to dangerous levels high enough to damage the colon.

What Complications Are Associated With Pseudomembranous Colitis

Complications of pseudomembranous colitis include the following:

  • Some people suffer reinfections with C. diff, which can cause pseudomembranous colitis to recur many times.
  • If your C. diff infection worsens, you may become dehydrated from frequent diarrhea. You may also temporarily lose the ability to pass stool.
  • In rare cases, pseudomembranous colitis causes toxic megacolon , intestinal perforation or sepsis. These conditions are medical emergencies that must be treated immediately.
  • Severe abdominal distention and pain
  • Rapid heartbeat

Symptoms Of C Diff Colitis

Symptoms of C. difficile infection typically begin 5 to 10 days after starting antibiotics but may occur on the first day or up to 2 months later.

Symptoms vary according to the degree of inflammation caused by the bacteria, ranging from slightly loose stools to bloody diarrhea, abdominal pain and cramping, and fever. Nausea and vomiting are rare.

Enhancing Healthcare Team Outcomes

C difficile is not only an annoying infection it can be associated with high morbidity and mortality. Today the emphasis is on prevention. All healthcare workers including nurses and pharmacists need to play a proactive role in preventing C.difficile colitis. When dealing with patients with C.difficile colitis, one should wear gloves and proper washing techniques. All staff and visitors need to be educated about hand hygiene. All hospital surfaces and inanimate objects need to be disinfected including thermometers, bedpans, doorknobs, and sinks. Patients who have a severe infection should be isolated. The pharmacist should regularly assess the need for antibiotics and gastric acid suppressants as these have been associated with severe C.difficile colitis.

Evidence-based Outcomes

Treatment Of Severe Pmc With Ileus Or Toxic Colon

Patients with an associated ileus or toxic colon represent a major therapeutic challenge because delivery of oral antibiotics to the colon becomes quite difficult. Therapy should include intravenous metronidazole which may penetrate the intestinal tissue at doses of 500 mg every 68 h .While some authors feel that intravenous vancomycin may have no role , other authors do favor the advice of Fekety and Shah who recommend the use of parenteral vancomycin as well as metronidazole. These authors feel that this is such a desperate clinical situation that anything that might help should be used. Vancomycin can be given by nasogastric tube or as enemas. A colonoscope can be used to decompress the colon and medicines can be delivered through a colon decompression tube. Rarely a surgical cecostomy may be necessary to decompress the colon and deliver the vancomycin to the colon lumen.

What You Can Do

When you make the appointment, ask if there’s anything you need to do in advance, such as fasting before having a specific test. Make a list of:

  • Your symptoms, including any that seem unrelated to the reason for your appointment
  • Key personal information, including major stresses, recent life changes and family medical history
  • All medications, vitamins or other supplements you take, including the doses
  • Questions to ask your doctor

Some basic questions you might want to ask your doctor include:

  • What’s the most likely cause of my symptoms?
  • What tests do I need?
  • Is my condition likely temporary or long lasting?
  • What treatments are available and which do you recommend for me?
  • I have these other health conditions. How can I best manage them together?
  • Are there restrictions I need to follow?
  • Should I see a specialist?
  • Are there brochures or other printed material I can have? What websites do you recommend?

Don’t hesitate to ask additional questions. And, if possible, take a family member or friend along to help you remember the information you’re given.

Enterohemorrhagic Escherichia Coli O: H7

Pseudomembranous Colitis – Histopathology

Escherichia coli is a gram-negative, facultative-anaerobic, rod-shaped bacterium that is ubiquitous in the environment and in humans and is associated with a range of clinical disease. Of particular importance is E. coli O157:H7, an enterohemorrhagic strain that was first described as a human GI pathogen in 1983.130 It is strongly associated with outbreaks of hemorrhagic colitis, often linked to the consumption of undercooked ground beef. The spectrum of clinical disease with E. coli O157:H7 is broad and includes asymptomatic carriage, non-bloody diarrhea, hemorrhagic colitis with frank bloody diarrhea, severe colitis with pseudomembrane formation, hemolytic-uremic syndrome , and thrombotic thrombocytopenic purpura .4,131,132 Enterohemorrhagic E. coli is able to cause clinical disease through the activity of specific enterotoxins, often called verotoxins or Shiga/Shiga-like toxins, because of their similarity to initially described Shigella toxins that cause hemorrhagic changes in the bowel mucosa.131,133 Shiga toxins have been shown to possess neurotoxic properties and cause intestinal secretion, microangiopathic changes, and an inflammatory response with cytokine production.134 Clinical presentation of E. coli O157:H7 varies greatly and can include abdominal pain, fever, vomiting, watery diarrhea, bloody diarrhea, and involvement of organ systems outside of the GI tract. Severe disease can be fatal.131,134

  • Treatments For A C Diff Infection

    If a doctor thinks you have a C. diff infection, they may ask for a sample of your poo to be tested.

    The infection can sometimes be treated at home, or you might need to go into hospital. This is because C. diff infections can sometimes lead to more serious problems like .

    A C. diff infection is treated by:

    • stopping any antibiotics you’re taking, if possible
    • taking a 10-day course of another antibiotic that can treat the C. diff infection

    You’ll also be given advice about how to avoid dehydration, such as making sure you drink plenty of water.

    Your symptoms should improve a few days after starting the new course of antibiotics. But it may be 1 to 2 weeks before the infection clears up completely.

    Go back to see the GP if your symptoms get worse, you feel very unwell after starting the antibiotics, or your symptoms come back afterwards.

    If your symptoms return, treatment may need to be repeated.

    Can Yogurt Prevent C Diff

    Probiotics can be found in dietary supplements or yogurts and are becoming increasingly available as capsules sold in health food stores and supermarkets. As ‘functional food’ or ‘good bacteria’, probiotics have been suggested as a means of both preventing and treating C. difficile-associated diarrhea .

    Causes Of C Diff Colitis

    The Spectrum of Pseudomembranous Enterocolitis and Antibiotic ...

    In C. difficileinduced colitis, the bacteria produce toxins that cause inflammation of the colon , usually after antibiotics are taken to treat an infection. Many antibiotics alter the balance among the types and quantity of bacteria that live in the intestine. Thus, certain disease-causing bacteria, such as C. difficile, can overgrow and replace the harmless bacteria that normally live in the intestine. C. difficile is the most common cause of colitis that develops after antibiotics are taken.

    When C. difficile bacteria overgrow, they release toxins that cause diarrhea, colitis, and the formation of abnormal membranes in the large intestine.

    A deadlier strain of C. difficile has been identified in some hospital outbreaks. This strain produces substantially more toxin, causes more severe illness with greater chance of relapse, is easier to transmit, and does not respond as well to antibiotic treatment.

    Almost any antibiotic can cause this disorder, but clindamycin, penicillins , cephalosporins , and fluoroquinolones are implicated most often. C. difficileinduced colitis can occur even after very brief antibiotic courses. C. difficileinduced colitis also may follow the use of certain cancer chemotherapy drugs.

    C. difficile infection is most common when an antibiotic is taken by mouth, but it also occurs when antibiotics are injected into a muscle or given by vein .

    People may also get the bacteria from pets or the environment.

    Which Drug Causes Antibiotics Pseudomembranous Colitis

    All antibiotics, except parenteral aminoglycosides, sulfonamides and vancomycin, can induce pseudomembranous colitis. The worst offenders are clindamycin, ampicillin, amoxicillin and the cephalosporins. The cytotoxin produced by Clostridium difficile has been identified as the cause of pseudomembranous colitis.

    How long after antibiotics can you get C diff?

    difficile may begin during antibiotic therapy or 5 to 10 days after the antibiotic is stopped less commonly, symptoms do not develop until as late as 10 weeks later.

    Can C diff cause long-term problems?

    The overall burden of C. difficile colitis is, therefore, huge. Patients with CDAD are at risk of not only treatment failure and/or early recurrence , but, as we show here, also long-term, debilitating, recurrent disease and death.

    Whats the best probiotic for C diff?

    The best studied probiotic agents in CDI are Saccharomyces boulardii, Lactobacillus GG and other lactobacilli, and probiotic mixtures.

    How Is Pseudomembranous Colitis Treated

    The first thing your doctor may recommend is that you stop taking the antibiotic that led to the pseudomembranous colitis infection.

    Pseudomembranous colitis is treated with antibiotics that target this infection. In most cases, doctors prescribe metronidazole , vancomycin or fidaxomicin for up to 14 days.

    Pseudomembranous colitis recurs in as many as 20% of people who have been treated. If this occurs, your doctor will prescribe another dose of an antibiotic.

    A newer treatment known as a fecal transplant uses stool from a healthy donor to help restore normal bacterial flora to your intestine, especially if the infection has returned after the first treatment.

    Can Pseudomembranous Colitis Be Prevented

    Pseudomembranous colitis from out-of-control growth of C. diff bacteria can be prevented by following basic sanitation practices:

    • Wash your hands often with soap and water.
    • Wash your hands after visiting anyone in a nursing home or hospital.
    • Disinfect surfaces with chlorine bleach-based cleaning products.
    • Dont use antibiotics except those prescribed by your doctor.
    • If caring for someone with C. diff, wear disposable gloves and wash your hands after all contact.
    • If your clothing becomes soiled with stool from someone infected with C. diff, wash your clothing with soap and chlorine bleach.

    Testing For C Difficile

    Enteritis vs Colitis, Enterocolitis – Symptoms, types, treatment and prognosis

    As most patients with pseudomembranous colitis have C difficile infection, it should be excluded first. Empiric anti-C difficile treatment is recommended in seriously ill-appearing patients, ideally starting after a stool sample is obtained.

    Diagnosis of C difficile infection requires laboratory demonstration of the toxin or detection of toxigenic organisms. The gold standard test is the cell culture cytotoxicity assay, but it is labor- and time-intensive. More widely available tests are polymerase chain reaction for the toxin gene or genes, enzyme immunoassay, and stool evaluation for glutamate dehydrogenase, which can yield results readily within hours.

    Polymerase chain reaction has a sensitivity of 97% and a specificity of 93%. Results can be falsely positive if empiric treatment is started before specimen collection, in which case C difficile DNA may still be present and detectable, but not the organism itself.

    Enzyme immunoassay for toxins A and B carries a sensitivity of 75% and a specificity of 99%, but 100 to 1,000 pg of toxin must be present for a positive result.,

    Glutamate dehydrogenase is an enzyme produced by both toxigenic and nontoxigenic strains of C difficile. As a result, stool testing for glutamate dehydrogenase is sensitive but not specific for C difficile infection, although multistep testing sequences have proven to be useful screening tools.

    Treatment Of C Diff Colitis

    • Stopping use of the antibiotics causing the colitis

    • Taking an antibiotic effective against C. difficile

    • In severe, recurring cases, a stool transplant

    If a person with C. difficileinduced colitis has diarrhea while taking antibiotics, the drugs are stopped immediately unless they are essential. After stopping the antibiotic, symptoms usually stop within 10 to 12 days. If the symptoms are severe or persist, people are usually given an antibiotic that is effective against C. difficile.

    Drugs that people sometimes take to slow the movement of the intestine and treat diarrhea are usually avoided. Such drugs may prolong the disorder by keeping the disease-causing toxin in contact with the large intestine.

    Most cases of C. difficileinduced colitis are treated with the antibiotic vancomycin, given by mouth. A relatively new antibiotic, fidaxomicin, appears to be quite effective and results in fewer recurrences of symptoms.

    Symptoms return in 15 to 20% of people with this disorder, typically within a few weeks of stopping treatment. The first time diarrhea returns, people are given another course of the same antibiotic. If diarrhea continues to return, they are usually given vancomycin for several weeks, sometimes followed by the antibiotic rifaximin. Fidaxomicin for 10 days is an alternative.

    Lifestyle And Home Remedies

    Some research suggests that concentrated supplements of good bacteria and yeasts can help prevent C. difficile infection, but more studies are needed for their use in treating recurrences. They are safe to use and available in capsule or liquid form without a prescription.

    To cope with the diarrhea and dehydration that can occur with pseudomembranous colitis, try to:

    • Drink plenty of fluids. Water is best, but fluids with added sodium and potassium also may be beneficial. Examples include sports drinks , oral rehydration solutions , noncaffeinated soft drinks, broths and fruit juices. Avoid beverages that are high in sugar or contain alcohol or caffeine, such as coffee, tea and colas, which can aggravate your symptoms.
    • Avoid irritating foods. Stay away from spicy, fatty or fried foods, and any other foods that make your symptoms worse.

    Occurrence In The United States

    In the United States, C difficile infection occurs primarily in hospitalized patients, causing as many as 3 million cases of diarrhea and colitis per year. Cancer patients are significantly affected by CDI healthcare-associated diarrhea. Diarrhea caused by C difficile is also linked to 14,000 American deaths annually.

    The incidence of reported CDI infection continues to increase. In the 1980s, McFarland et al reported that 7% of patients admitted to a hospital and 28% of patients who were hospitalized had positive cultures for the organism. By the 1990s, the incidence of C difficile in hospitalized patients had risen to 30-40 per 100,000 population, and by 2005, to 84 per 100,000 population.

    Indeed, in contrast to the incidence rates of other nosocomial infections, which declined from 2000 to 2009, the number of hospitalized patients with any CDI as a discharge diagnosis more than doubled in the same period, from approximately 139,000 to 336,600. Furthermore, the number of patients with a primary diagnosis of CDI more than tripled, from 33,000 to 111,000.

    New CDI populations have emerged, and studies have challenged the notion that C difficile is primarily a hospital infection, as more cases are being seen in the community. These cases include patients with community-acquired infection and no previous antibiotic exposure, pregnant women, and patients with inflammatory bowel disease .
