Around 20-30% of the antibiotic-related diarrhea cases are caused by Clostridium difficile (C difficile). It is also the most frequent cause of contagious diarrhea in the healthcare system. If we look over the previous decade, the overall incidence rate of Clostridium difficile has raised and the outbursts of dangerous strains have been recognized. Besides, the threat of community-acquired Clostridium difficile has turned out to be more ordinary.
Non-alterable threat aspects for clostridium difficile infection
The Infectious Diseases Society of America (IDSA) outlined some vital aspects of the threat of C difficile infection.
- Older Age
People of older age, particularly 65 years of age or above are a non-modifiable factor of risk to reduce the chances of getting this infection
- Hospitalization
Hospitalization is another non-adjustable risk factor for C difficile infection.
It is important to know that the factors like older age and hospitalization are non-modifiable to trim down the risk of Clostridium difficile diarrhea infection.
Antibiotics: The most vital alterable factors of threat for contagion
Nearly every antibiotic is competent in distracting the basic microflora, which enables clostridium difficile to boom and generates toxin. Astonishingly, a minor dosage of antibiotics for surgical prevention is related with an accelerated threat of clostridium difficile infection. In general, the longer length antibiotic and compound antibiotic are two factors of the threat of antibiotic-associated C difficile diarrhea. These are two customary antimicrobial stewardship principles. However, the IDSA guiding principle is mute concerning some particular antibiotic drugs that may hold a high threat of Clostridium difficile infection.
Numerous readings have been done to way in the relative threat of various antibiotics for C difficile disease. Even though, there is dissimilarity in the existing studies. Numerous analyses have wrapped up parallel results regarding which antibiotics classes are at the peak danger for C difficile disease.
Antibiotic groups with chief threats of C difficile (probable relative amount 5 or more)
- Clindamycin bears the maximum danger of C difficile infectivity with a probable relative amount of around 17-20 evaluated to no antibiotic experience.
- Fluoroquinolones, cephalosporins, aztreonam, and carbapenems hold a moderately high threat, all of which being related with a probable relative amount of something like 5 liken to no antibiotic experience.
Antibiotic groups with the temperate threat of C difficile (probable relative amount 1 to 5)
- Penicillins, sulfonamides/trimethoprim, and Macrolides are linked with a reasonable threat of C difficile infectivity with probable relative amount amid about 1.8 and 3.3.
- In this class, penicillins are usually related to a little high danger (the probable relative amount of around 50% higher) liken to sulfonamides/trimethoprim and macrolides.
Medical implications of C difficile threat statistics.
- Based on prearranged data, clindamycin should entirely be shunned amid the people who are at elevated threat of clostridium difficile infectivity. Particularly, the elderly people, and who are at recurrent antibiotic experience, and hospitalizations.
- In hospitalized patients with harsh infections who need anti-Pseudomonal exposure, the accessible facts propose that penicillins (such as piperacillin/tazobactam) may well have a lesser threat of C difficile infectivity vs. carbapenems (such as meropenem) or cephalosporins (such as cefepime). Though this danger is related to the choice of antimicrobials, local resistance sample should also be believed when picking an agent.
It is crucial to have a familiarity with high-threat and lower-threat antibiotics for clostridium difficile infection, mostly in patients who are prone to a high danger for clostridium difficile infectivity, like aged patients.
