Harvard Health Publishing Logo


Clostridioides (beforehand Clostridium) difficile (C. diff) is the commonest explanation for diarrhea amongst hospitalized sufferers and probably the most generally reported micro organism inflicting infections in hospitals. In a 2019 report, the CDC referred to C. diff as “an pressing menace.”

Who’s most in danger?

C. diff an infection (CDI) happens extra generally following antibiotic remedy or hospitalization, and amongst older adults or sufferers with weakened immune responses. In 2002, an epidemic pressure of C. diff emerged, inflicting extra extreme illness with irritation of the colon (colitis) and a rise in deaths. This pressure adheres higher to the gut and produces extra toxin, which is chargeable for inflicting sickness. Non-epidemic strains could trigger much less extreme illness.

What makes C. diff so troublesome to deal with?

A excessive relapse price poses challenges to treating folks with CDI. Recurrence of diarrhea following preliminary remedy happens in about 20% of circumstances. The chance of yet one more relapse is even higher within the weeks following remedy for a recurrent CDI.

C. diff produces spores (dormant cells able to surviving harsh situations for extended intervals) that may contaminate the atmosphere. Spores are hearty and proof against routine cleansing. However enhanced protecting measures — cautious hand washing, isolation precautions for contaminated sufferers (personal room, robe, and gloves), and cleansing with brokers able to killing C. diff spores — are efficient methods to forestall transmission and management CDI.

Antibiotics disrupt the wholesome intestine micro organism (microbiome), which then offers appropriate situations for ingested spores to flourish and end in CDI.

Hospitalized sufferers are at higher danger, though wholesome people in the neighborhood who haven’t been handled with antibiotics also can develop into contaminated.

The World Society of Emergency Surgical procedure launched up to date scientific observe tips in 2019, specializing in CDI in surgical sufferers. Surgical procedure, notably gastrointestinal surgical procedure, is a recognized danger for CDI. (Satirically, surgical procedure can also be a possible remedy possibility for extreme CDI.)

What’s the distinction between C. diff colonization and C. diff an infection?

As much as 5% of individuals in the neighborhood, and a good higher share of people who find themselves hospitalized, could also be colonized with C. diff micro organism, however not expertise any signs. The chance of progressing to illness varies, since not all C. diff strains produce toxin that makes you sick. Individuals colonized with a non-toxin-producing pressure of C. diff may very well be protected against CDI.

CDI is identified based mostly on signs, primarily watery diarrhea occurring no less than 3 times a day, and stool that checks optimistic for C. diff. A optimistic take a look at with out signs represents colonization and doesn’t require remedy. Sufferers colonized with toxin-producing strains are in danger for illness, notably if uncovered to antibiotics.

How is C. diff handled?

The most typical antibiotics used to deal with CDI are oral vancomycin or fidaxomicin. Prolonged regimens, lasting a number of weeks, have been used efficiently to deal with recurrences. Vancomycin enemas and intravenous metronidazole, one other antibiotic, are additionally utilized in extreme circumstances.

Fecal microbiota or stool transplant (FMT) from screened donors is an efficient investigational remedy for individuals who don’t reply to different remedy. Nonetheless, it isn’t with out danger. FMT capsules are efficient and logistically simpler.

Sufferers with extreme CDI not responding to remedy could profit from surgical procedure, sometimes a colon resection or a colon-sparing process.

You probably have a longtime (non-C. diff) bacterial an infection, a number of latest research present that shorter antibiotic programs are efficient and may additionally cut back your danger of CDI. You also needs to ask your physician about avoiding antibiotics which might be extra more likely to end in CDI (clindamycin, fluoroquinolones, penicillins, and cephalosporins).

If you’re hospitalized with CDI, it’s best to use a delegated rest room and wash your palms steadily with cleaning soap and water, notably after utilizing the restroom. Within the hospital, encourage employees to observe hand hygiene in your line of sight, and categorical appreciation to hospital employees for holding your atmosphere germ-free. If you’re at excessive danger for a CDI recurrence (you’re 65 or older, have a weakened immune response, or had a extreme bout of CDI), focus on the potential worth of bezlotoxumab along with your supplier. This monoclonal antibody may help to additional cut back danger of recurrent CDI in those that are at excessive danger for recurrence.

There are different preventive measures which you can take whether or not or not you’re hospitalized. Restrict using antacids, notably proton-pump inhibitors (PPIs). Don’t ask your physician for antibiotics to deal with colds, bronchitis, or different viral infections. Request training about uncomfortable side effects of prescribed antibiotics out of your physician or dentist, and focus on the shortest efficient remedy length on your situation. Let your physician know that you just wish to decrease your danger for CDI.
