Clostridium Difficile Infection (CDI)

Clostridium difficile infection or CDI is a disease that is caused from a severe mishap of the microbiota in the gut by antibiotics. This causes the patient to have persistent diarrheal problems from mild symptoms to very extreme and severe symptoms. In the past twenty years, this infection has been on the rise in numbers of problems in public health and has even caused a number of deaths. Although this is not the only infection the transplant can help conquer, C.difficile a great example to portray since in the past ten years it has become a growing health problem.

Clostridium difficile is a gram positive, spore forming anaerobic bacillus, which may or may not carry the genes for toxin A-B production (Nipa, 2010). These two types of protein exotoxins produced by the Clostridium difficile bacillus, toxin A and toxin B, can have an infectious form and a non-active, non-infectious form (Grossman, 2010). The infectious form can survive for a short duration of time in the environment. The spores can survive for a longer period of time in the environment and are not infectious unless and until they are ingested or are transformed into an infectious state (Nipa, 2010).

This paper will mainly explain what Clostridium difficile is, its causal agent, epidemiology, ways of transmission, some clinical features, diagnoses and how to test for the bacterium, treatment, prognosis, and preventative measures. There are treatments available for this

Clostridium difficile is a Gram-positive, spore-forming, rod-shaped bacillus that is renowned for being the leading cause of hospital-acquired diarrhea in adult patients. C. difficile is present as normal intestinal flora within 3% to 5% of healthy people2, while its spores are ubiquitous in the environment, especially in hospital settings. It grows at an optimal temperature and pH of 37ºC and 6.5–7.5 respectively.1 It is an obligate anaerobic as it thrives in the absence of oxygen. It is highly motile with the presence of peritrichous flagella, which are evenly spread out along its surface. As briefly mentioned above, this evolving pathogen produces endospores. The bacterium produces dormant spores, which are extremely hardy and resistant to antibiotics, the host’s innate immune system, and once shed into the environment through the host’s feces, they are resistant to unfavorable aerobic conditions3 as well as several types of bleach-free disinfectants, which are commonly used in hospitals.3 The spores will germinate under the favorable conditions of the intestinal tract, resulting in the multiplication of vegetative cells, colonizing in the gastrointestinal tract. The vegetative cells release two powerful exotoxins upon adherence to the epithelial cells of the GI tract. Pathogenic strains of C. difficile produce two exotoxins: toxin A and toxin B. Toxin A is an enterotoxin that causes fluid excretion, resulting in fluid accumulation and watery diarrhea. Toxin B is a potent

C-Diff is an anaerobic gram-positive spore forming bacterium, which affects and grows in the gastrointestinal tract after the normal intestinal flora, has been changed by antibiotic therapy or by contact through the fecal- oral route (Kelly & Lamont, 2014). The C-Diff organism, releases two different toxins, toxins A & B. Both toxins are cytotoxic for many different cells. Toxin B is more potent then A, both toxins cause increased vascular permeability by opening tight junctions between cells, which cause hemorrhage, these toxins also stimulate the

Many Americans die each year from complications connected to Clostridium difficile. It can ill a significant number of individuals as well as animals. The Clostridium difficile infection is the result of poor hygiene, misuse, overuse of antibiotics and an aging population. In this paper I will be discussing the following topics, what clostridium difficile means, what it causes, signs and symptoms, complications, treatment and the prevention.

Clostridium difficile is a gram-positive, spore-forming, anaerobic bacillus. Since the turn of the 21st century, there has been a dramatic increase in the number of nosocomial infections associated with antibiotic exposure and an increase in the severity of the disease. Challenges of disease containment include emerging risk factors and recurrence. In 2008 the acute care costs, not including the economic burden placed outside of the hospital, was estimated to be around $4.8 billion in the US. As such, it has become clear that preventative measures are needed to monitor and reduce the risk of infection and recurrence.

761). Since the nutrients in the intestines are available due to the good bacteria being destroyed, Clostridium difficile uses the nutrients to multiply and releases the toxins , which attack the lining of the intestines, thus causing colitis (Fordtran, 2006, pp. 3).

Clostridium difficile involves a gram-positive spore-forming bacterium, which is a normal element of the colon flora in people. The Clostridium difficile can cause antibiotic-associated diarrhea when the competing bacteria in the gut flora are all killed by antibiotic treatment. The Clostridium difficile infection is one of the serious healthcare-related infection and also a rising health care problem. In the early 1970s, the Clostridium difficile has been known to have the ability to cause pseudomembranous colitis. As stated, the infection is the most cause of nosocomial infectious diarrhea (Aktories & Wilkins, 2000). Individuals that are colonized with clostridium difficile serve as the reservoir for infection and this is by contaminating the environment with spores of such bacteria. This will lead to the spread of the organism on the health care worker’s hands or even through the use of medical equipment. In this paper, we are going to focus on the effective prevention strategies for clostridium difficile. What are the effective prevention strategies for clostridium difficile?

“Clostridium difficile is a gram positive, spore forming anaerobic bacillus, which may or may not carry the genes for toxin A-B production” (Patel 102). In the 1930’s, Hall and O’Toole

Ample literature has been published to elucidate the pervasive nature of Clostridium difficile and its relationship with inadequate health-care practices. Clostridium difficile-associated disease: New challenges from an established pathogen by Sunshine and McDonald, published in the Cleveland Clinic Journal of Medicine discusses the concern over Clostridium difficile. It includes a case report involving infection caused by the bacterium and important guidelines for prevention and treatment associated with the bacterium.

Ingestion of the endospore causes infection. Once it reaches the preferred anaerobic environment of the gut, the endospores germinate and begin releasing toxins A and B (Burns & Minton 2011). The presence of C. difficile does not necessarily mean infection. A patient can be positive for C. difficile but have normal stool, which means there is colonization without infection. Patients who have the C. difficile pathogen without experiencing any symptoms allow it to be passed along undetected which contributes to the ongoing spread to others. Only when toxin A and toxin B are released at suitable levels does C. difficile become pathogenic to humans. Once infected, typical symptoms include watery diarrhea, abdominal pain, colitis, fever, and fecal leukocytes. Moderate to severe Clostridium difficile infection (CDI) consist of profuse diarrhea, abdominal distention, leukocytosis, systemic inflammatory response, pseudomembranous colitis, megacolon and death (Sunenshine & McDonald, 2006). With the combination of a highly resilient endospores, and asymptomatic carriers, this allows C. difficile to persist in the environment and spread to patients with compromised immune systems, or older patients who have a high risk of contracting CDI with a higher severity than healthy adults (Laffan, Bellantoni, Greenough, Zenilman, 2006).

CDI cannot be treated with many antibiotics, and as early as 2000 another strain appeared that was resistant to even more antibiotics, including fluoroquinolones (“Antibiotic/Antimicrobial Resistance.”). This new strain creates more toxins and can show up in people not normally considered at risk for CDI infection, like those who have not been hospitalized or treated with antibiotics (“C. difficile infection.”). This aggressive strain only adds more danger to an already resistant bacteria. As antibiotics became more common, they were prescribed for thousands of common illnesses. Over time, Clostridium difficile has built up a resistance to antibiotics to become a major concern. Even more frightening, it has started to appear in the community. In fact, the Centers for Disease Control rate it as an urgent threat. Superbugs like CDI are becoming a more ever-present threat and we must continually work towards newer and more effective treatments to counteract the bacterias frightening ability to resist us (“Antibiotic/Antimicrobial Resistance.”). CDI is just one of many superbugs, however, and others pose just as great a

Clostridium difficile has infected up to 500,000 people in the United States every year. Clostridium difficile is a bacterial infection it can cause diarrhea and also a fever. It has also caused death among people. There has been a recorded 14,000 deaths from Clostridium difficile a year.

Most of the public have heard of broad-spectrum drugs, especially in terms of antibiotic resistance, because they fight a wide range of bacteria but also kills normal flora in the gut (Haddox, 2013). The loss of this gut flora can lead to an abnormal growth of harmful bacteria such as clostridium difficile (C-Diff). The four “C” antibiotics that have a high risk for patient to develop C-diff are clindamycin, cephalosporins, coamoxiclav, and ciprofloxacin (Haddox, 2013). These antibiotics have the highest risk of leading to C-diff development, however all antibiotics increase a patient’s likelihood of a C-diff infection. This effect can last up to 12 weeks post antibiotic administration (Haddox, 2013).
