How Common Are Repeat Cdiff Infections
The rate of repeat infection varies from 5% to 50% among patients with a resolved first infectionthe recurrence rate varies according to risk factors like age, exposure to hospital environments, and an underlying disease like kidney failure. However, the typical recurrence rate among patients is approximately 20%.
Among patients who have already experienced a C. diff infection twice, the rate of reinfection is approximately 45% to 65%.
Collection Of Faecal Samples
Faecal samples were collected by patients into sterile containers just prior to initiation of UTI treatment , at its completion and 1week after initiation . The samples were kept frozen until retrieval by the research assistant, transported on ice to the laboratory and stored at 80°C until used.
Can C Diff Infections Be Prevented
There are steps you can take to try to prevent getting or spreading C. diff:
- Wash your hands with soap and water after you use the bathroom and before you eat.
- If you have diarrhea, clean the bathroom that you used before anyone else uses it. Use bleach mixed with water or another disinfectant to clean the toilet seat, handle, and lid.
Health care providers can also help prevent C. diff infections by taking infection control precautions and improving how they prescribe antibiotics.

The Use Of Probiotics To Prevent Clostridium Difficile Diarrhea Associated With Antibiotic Use
What is Clostridium difficile-associated diarrhea?
Antibiotics are among the most prescribed medications worldwide. Antibiotic treatment may disturb the balance of organisms that normally populate the gut. This can result in a range of symptoms, most notably, diarrhea. Clostridium difficile is a particularly dangerous organism that may colonize the gut if the normal healthy balance has been disturbed. Clostridium difficile-related disease varies from asymptomatic infection, diarrhea, colitis, and pseudo-membranous colitis to toxic megacolon and death. The cost of treatment is expensive and the financial burden on the medical system is substantial.
What are probiotics?
Probiotics are live organisms . thought to improve the balance of organisms that populate the gut, counteracting potential disturbances to the gut microbial balance that are associated with antibiotic use, and reducing the risk of colonization by pathogenic bacteria. 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 .

How Is C Diff Transmitted
Although antibiotics are the most common cause of c. diff, the infection can also spread in hospital and community settings. In hospitals, c. diff is spread by touching unclean hospital surfaces or the hands of health care providers, especially if the providers are using hand sanitizer instead of soap and water to clean their hands. In the community, c. diff can spread through direct contact with an infected person. Fortunately, most healthy adults who come in contact with c. diff are not likely to get sick. Eighty percent of infections occur in people older than 65 years of age.
New Recurrent C Diff Treatments Being Researched
Summit Pharmaceuticals is evaluating an investigational drug called Ridinilazole to determine its safety and efficacy in treating Clostridioides difficile and to help reduce the risk of C. diff coming back. Ridinilazole is designed specifically to target the C. diff bacteria, which could potentially mean less damage to the gut and a reduced chance of another infection.

When Is Testing Indicated
Testing for C. difficile infection should be considered in patients presenting with at least three unformed stools in 24 hours.
Evidence Summary
Patients should be asked about antibiotic use in the past three months, including single perioperative doses. Symptoms vary from mild diarrhea to fulminant colitis, which can be complicated by toxic megacolon, bowel perforation, and sepsis. Less than one-half of patients with C. difficile infection have fever, abdominal discomfort, or leukocytosis. Although occult blood may be present in the stool, melena and hematochezia are uncommon.2 Ileus is a rare presentation of C. difficile infection.10 Guidelines from the American College of Gastroenterology recommend testing all patients with inflammatory bowel disease hospitalized with a disease flare-up.11

Precautions And Possible Complications
Its a good idea to get tested for C. diff if you exhibit symptoms, especially if symptoms occur during or after taking antibiotics or after being around someone that you know has a C. diff infection.
What complications can C. diff cause? If the infection worsens, you may become seriously dehydrated, be unable to pass stool and/or experience weight loss. C. diff can also lead to a toxic megacolon, which may require emergency surgery or bowel perforation, which can lead to a dangerous infection called peritonitis. Can C. diff kill you? Rarely, a C. diff infection can lead to a hole in the intestines or , which can be deadly. In severe cases, surgery may be required to remove the infected part of the colon.
Can you kiss someone with C. diff? Its usually considered OK to kiss and hug someone with C. diff since the infection is not typically spread through touching, and it also is not spread through the air by things like sneezing or coughing. However, if you visit someone hospitalized with C. diff, you should take some key C. diff precautions, including wearing gloves while in the room and washing your hands before leaving their room. Wearing gloves and practicing good hand washing hygiene is also very important for people who work in hospitals and long-term care facilities.
How Is Mrsa Treated
Although MRSA is resistant to most drugs, it still responds to certain medications. Most doctors rely on intravenous vancomycin or other antibiotic drugs in its class to treat resistant bacteria. Many less severe staph skin infections can be treated by draining any abscesses or boils. Additionally, applying prescribed antiseptics and creams to the site of infection can decrease the amount of bacteria in the body. This should only be done by a healthcare professional.

What Increases My Risk For A C
You may be at a greater risk for getting a C-diff infection if:
- You have been taking an antibiotic during the past 30 days. Antibiotics can kill the good germs in your intestines.
- You have an immune system that is weak from a major chronic illness.
- You are a woman 65 or older.
- You take medicine for heartburn or to lower the acid in your stomach. These medicines include Prevacid®, Tagamet®, Prilosec®, or Nexium®.
- You have been in the hospital, especially in an intensive care unit, or you live in a nursing home.
C-diff infections occur most often in hospitals, nursing homes, and other places where there are more people who are sick or who are taking antibiotic medicines.
What Is Clostridium Difficile
Clostridium difficile is a bacterium that causes mild to severe diarrhea and intestinal conditions like pseudomembranous colitis . C. difficile is the most frequent cause of infectious diarrhea in hospitals and long-term care facilities in Canada, as well as in other industrialized countries.
Most cases of C. difficile occur in patients who are taking certain antibiotics in high doses or over a prolonged period of time. Some antibiotics can destroy a person’s normal bacteria found in the gut, causing C. difficile bacteria to grow. When this occurs, the C. difficile bacteria produce toxins, which can damage the bowel and cause diarrhea. However, some people can have C. difficile bacteria present in their bowel and not show symptoms.
There are many different strains of C. difficile and one strain, North American Pulsed Field type 1, known as NAP1, is likely to cause serious illness.

What Causes Antibiotic Resistance
When a person takes an antibiotic, the drug kills bacteria, but a few can survive. These surviving bacteria are resistant to that antibiotic. They then multiply. This means that every time a patient takes an antibiotic, he or she is creating more drug-resistant bacteria. Although bacterial antibiotic resistance is an evolutionary process, societal factors also contribute to the problem. The inappropriate use of antibiotics contributes to the growing number of antibiotic-resistant bacteria today. For years, antibiotics have been prescribed for colds, earaches, flu, and other infections that normally clear up on their own. Inappropriate use of antibiotics, such as not taking doses as prescribed or taking antibiotics for viral infections, can also contribute to the emergence of antibiotic-resistant bacteria.
In recent years, antibacterial household products have become common in household cleaners, soaps, detergents, hand lotions, tooth brushes, and sometimes even plastic containers and mattresses. Although people buy these products with the intent of protecting their family from harmful germs, the widespread use of antibacterial products helps to produce resistant bacteria. As with antibiotic medications, it is important to be cautious when using these products.
What Causes A C
Your intestines have many good germs in them that help you digest food. A C-diff germ enters your body when you eat or swallow something that has C-diff on it. The germ moves to your intestines. A healthy person with a normal immune system and normal good germs may not get sick. But if your immune system is weak or these good germs have been killed by an antibiotic you may be taking for a different kind of infection, C-diff may grow in your intestines and cause diarrhea. This is called a C-diff infection.

Refinements To Fecal Microbiota Transplantation: Use Of Fecal Derivatives For The Treatment Of Cdi
Treatment with undefined consortia of fecal bacteria that are quality-controlled and semi-standardized is another avenue of therapy being explored. RBX2660 is a standardized stool-derived microbial suspension containing live bacteria in a cryopreservative derived from screened healthy donors. This microbial suspension can be stored frozen and then thawed and delivered to patients via retention enema.
A phase 2 single-arm study of 34 patients assessed safety and efficacy of RBX2660 in non-immunocompromised patients with â¥two recurrences of CDI. Patients with persistent diarrhea after a first RBX2660 dose could receive a second dose within ten days. Of 31 patients evaluated for efficacy, 14 required a second treatment, and 27 of 31 had treatment success after one or two doses. This study shows the promise of a standardized fecal microbial suspension that is easy to administer, though the patient sample was small and the first dose efficacy was suboptimal. However, a follow-up phase 2b trial of 150 subjects receiving two doses of RBX2660 versus placebo failed to meet its primary end point of absence of CDI at 56 days . Larger randomized trials will be needed to further assess efficacy for recurrent CDI.
How Can Hospitals And Care Homes Prevent The Spread Of Clostridium Difficile
Clostridium difficile bacteria can spread easily, particularly in healthcare environments, such as a hospital or care home. It may not be possible to prevent the bacteria from spreading altogether. However, a number of precautions can be taken to reduce the risk of infection.
Healthcare workers should wear disposable gloves and aprons when caring for anyone who has a Clostridium difficile infection. Whenever possible, people who are infected with Clostridium difficile should have their own room and toilet facilities to avoid passing the infection onto others.
Staff, patients and visitors should be encouraged to wash their hands regularly and thoroughly. Alcohol hand gel is not effective against Clostridium difficile spores, so the use of soap and water is essential.
Surfaces that may have come into contact with the bacteria or spores, such as toilets, the floor around toilets, bedpans and beds, should also be cleaned thoroughly with disinfectants with proven effectiveness against Clostridium difficile. Many hospitals now use peracetic acid wipes on commodes etc.
The Department of Health advises that doctors prescribe antibiotics cautiously to try to reduce the amount of broad-spectrum antibiotics being given to patients. This is to help cut down the number of people who are vulnerable to an infection.
Wash your hands before and after contact with the patient, and before handling food.

How And Where You Get C Diff
Most people who develop a C. diff infection are taking an antibiotic or took one in the previous few months. In addition to harmful bacteria, antibiotics also destroy the protective bacteria that normally live in the intestines for up to several months. That allows dangerous C. diff bacteria an opportunity to take hold and multiply.
Half of hospitalized patients receive an antibiotic during their stay, according to the CDC, leaving them particularly vulnerable to C. diff. And unless the hospital is scrupulous about hand-washing and disinfection, the bacteria can easily spread from one patient to the next via hospital staff or equipment.
Doctors typically treat infected patients with another antibiotic, one capable of killing C. diff bacteria. But once-reliable antibiotic treatments are no longer working in many cases, according to Lewis’s study. More patients have persistent or recurring diarrhea and other symptoms of C. diff for two months or longer, even after being treated with three or more courses of different antibiotics.
Direct Inhibition Of C Difficile
Certain bacteria produce antibacterial compounds, that could prevent or treat CDI. This can include molecules such as the bacteriocin produced by Bacillus thuringiensis DPC 6431. Other bacteria produce non-protein antimicrobial compounds. Lactobacillus reuteri ferments glycerol to produce reuterin, an antibacterial substance with activity against numerous enteric pathogens, including C. difficile. A recent study by Spinler and colleagues utilized L. reuteri strain 17938, which displays high-level resistance to vancomycin, metronidazole, and fidaxomicin, making it an attractive option in patients receiving concomitant anti-CDI therapy. These investigators utilized a mini-bioreactor system that contained a human-derived microbial community to compare the ability of L. reuteri 17938 with or without the addition of glycerol to inhibit C. difficile growth in bioreactors pretreated with clindamycin. The combination of L. reuteri and glycerol resulted in a 5-log reduction in the growth of C. difficile in these bioreactors .

What Puts A Person At Risk Of Getting C Difficile Infection
People in healthcare settings are most at risk of acquiring this type of infection because C. difficile is often a healthcare-associated infection. These types of infections can be transmitted within a hospital when infection prevention and control measures are not followed.
Those at higher risk include the elderly, people with severe underlying illness, and people taking certain antibiotics or cancer chemotherapy. In addition, patients taking stomach ulcer drugs, known as proton pump inhibitors, are at increased risk for contracting C. difficile infection.
How Can It Be Treated
You will only need treatment for a Clostridium difficile infection if you have symptoms. No treatment is needed if the bacteria are living harmlessly in your gut. Clostridium difficile can be treated with specific antibiotics, rather than broad spectrum antibiotics. There is a risk of relapse in 20-30% of patients and other treatments may be tried, there is now good evidence that for a small number of patients who suffer repeated infections, treatment by giving them a stool transplant from a healthy donor can restore gut bacteria and cure the infections in the majority of cases. Most cases of Clostridium difficile diarrhoea make a full recovery. However, elderly patients with other underlying conditions may have a more severe course. Occasionally, infection in these circumstances may be life threatening.
For mild or moderate symptoms of Clostridium difficile infection, it is best to stop taking the antibiotics that may have caused the infection, if this is possible. This will allow the natural ‘good’ bacteria to regrow in your gut. In many cases where the symptoms are mild or moderate, this is often enough to ease the symptoms and clear the infection.
If you have symptoms that are more severe, such as severe diarrhoea or colitis , you may need to take an antibiotic that can kill Clostridium difficile bacteria. This will usually be either metronidazole or vancomycin, which should ease the symptoms within two to three days.
