What Caregivers Need to Know About C. Difficile - glovnomesgui.tk
Why not share! While most of these therapeutics are still in the laboratory phase, their emergence might provide future therapies for the treatment of CDI. The potential use of bacteriophage lysin proteins is one of such emerging strategies. A bacteriophage lysin protein and its catalytic domain PlyCD cloned from the prophage sequence harbored in C.

Indeed, the catalytic domain PlyCD was found to have a broader lytic spectrum against this pathogen In addition, subinhibitory doses of vancomycin combined with the PlyCD catalytic domain in vitro were significantly more bactericidal against C. This suggests a defense mechanism for human defensins against some types of clostridial glucosylating cytotoxins It is suggested that HD-5 used in combination with FMT therapies would be useful for treating recurrent forms of CID due to the antitoxin, bactericidal, and immunostimulatory effects of such a treatment Another more recent study has described a synthesized, bioactive, low molecular weight organoselenium compound, ebselen, that directly targets the glucosyltransferase domain GDT of C.
This agent was found to have a good activity against both TcdA and TcdB , and in treatment tests in a mouse model that closely resembles human infection, treatment with ebselen reduced the disease pathology in murine tissues by inhibiting the release of the toxic GDT Tolevamer is a non-absorbable high molecular weight anionic polymer that could potentially absorb the toxins TcsA and TcdB involved in CDI. Clinical trials evaluating tolevamer for the therapy of CDI have been initiated.
Even though a lower CDI recurrence rate 4.

However, anion-binding resins might still be useful as a substitute for antibiotics as an emerging alternative for the treatment of CDI. The current status of CDI management is still worrisome. Therefore, active prevention will play an increasingly important role in managing this disease more effectively. As most CDIs are hospital-acquired, and C. Healthcare workers and visitors must use gloves and gowns on entry to a room of a patient with CDI, and they are required to wash hands with soap or antimicrobial soap and water after caring for or otherwise having contact with these patients; patients with CDI should be accommodated in a single room with contact precautions, or at least, patients should be cohorted and provided with a dedicated commode for each patient when private rooms are not available 5 , Moreover, environmental cleaning and disinfection also are important for reducing C.
Any potential environmental sources of C. Antibiotic stewardship is another important aspect for the prevention and control of CDI, as antibiotic use is regarded as the most important risk factor for CDI 1 , Almost all antibiotics have been associated with CDI, but ampicillin, amoxicillin, cephalosporins, clindamycin, and fluoroquinolones are the most frequently cited 1. Therefore, implementation of an antimicrobial stewardship program is recommended; this program should minimize the frequency and duration of antibiotic therapy in general and specifically restrict the use of those antibiotics most frequently associated with CDI i.
The effect of using probiotics to help prevent and control CDI is uncertain at present. While a number of investigators have documented that the use of probiotics composed of various microbial strains had an effect on preventing AAD as well as CDAD 84 , 85 , 86 , 87 , 88 , other researchers have found no benefit with the administration of probiotics for the prevention of CDI 89 , 90 , 91 , 92 , Therefore, the routine use of probiotics for preventing CDI is not recommended at present 1 , 5.
In addition to the above recommendations, rapid diagnostic testing of the patients with diarrheal illness acquired in the hospital or associated with antimicrobial therapy is recommended A hospital-based infection prevention program combined with active surveillance also has been proposed to decrease the incidence of CDI It is widely known that C.
Although there is still a lack of direct evidence that CDI can be transmitted between animals and humans through contact, a large number of studies have demonstrated a close phylogenetic relationship between C. In particular, the hypervirulent isolate has been commonly detected in farm animals as well as in human cases of CDI in North America and Europe. Moreover, this hypervirulent strain also has been frequently detected in meat products It has been postulated that direct transmission of ribotype strains has occurred between pigs and humans in the Netherlands Cases of human CDI caused by a livestock-associated ribotype strain recently have been reported in Western Australia These findings would seem to confirm the possibility that C.
In addition, because C. Although antimicrobial therapy remains the first choice for CDI, alternate treatment strategies such as FMT and surgical intervention should be considered. Because of the reduction of susceptibility of C.
While many guidelines have been suggested for the control and prevention of CDI, proper diagnostic testing and antimicrobial stewardship are the most important factors because antibiotic use remains the most important risk factor for CDI in the absence of effective vaccines.
However, some non-medical factors such as proper management of pets and food-producing animals as well as developing good food practices should not be ignored.

Introduction Clostridium difficile infection CDI has become a significant healthcare-associated infection with a considerable economic impact throughout the world and is particularly important in developed countries. Current laboratory diagnosis An effective diagnosis of CDI requires both clinical symptoms and a positive laboratory test 7 , Open in a separate window. Bacterial targets for CDI therapeutics.

Test algorithms for the diagnosis of Clostridium difficile infection. Strain typing Strain typing also may be an important component of the laboratory diagnosis of CDI. Current antibiotics for the therapy of CDI Antimicrobial therapy remains the first choice for CDI, and specific antimicrobial therapy guideline recommendations should be based on the severity of the disease.
Emerging antibiotics There are a number of antibiotics that are currently being evaluated for the therapy of CDI. Alternative treatment strategies Since the expression of clostridial toxins TcdA and TcdB is mandatory for the development of CDI, the development of agents such as monoclonal antibodies aimed at preventing the cytotoxic effect of these toxins is a sensible strategy for controlling the disease. Emerging strategies for the therapy of CDI Due to the continued development of science and technology, a number of non-antibiotic therapeutics are emerging that may be useful for the therapy of CDI.
Future perspectives The current status of CDI management is still worrisome. References 1.
