Pseudomembranous Colitis (Clostridium Difficile Infection): Risks and Treatment Strategies
Pseudomembranous colitis (PMC) is an antibiotic associated severe inflammatory condition of the colon caused by an overgrowth of Clostridium difficile (C. difficile), a toxin producing bacterium. It's known for forming yellow-white plaques – called pseudomembranes – on the lining of the colon which can be seen during colonoscopy or on histology [1], [6]. Although often linked to antibiotic use, PMC can present with a wide range of severity from mild diarrhea to life threatening colitis.
While Clostridioides difficile (formerly Clostridium difficile) is the primary organism behind PMC, it's not the only one. Other pathogens have occasionally been found to cause similar colonic inflammation and pseudomembrane formation [1], [3]. But C. difficile is the most common and clinically relevant.
The process starts with antibiotics. These medications while useful for treating bacterial infections can disrupt the balance of normal colonic flora in the gut. This gives C. difficile – often present in small amounts in the intestines – the opportunity to flourish [2], [7], [9]. Spores that were once dormant now find an environment ripe for growth.
C. difficile produces two potent toxins, toxin A (TcdA) and toxin B (TcdB). These toxins bind to cells lining the colon, damaging them and setting off a cascade of inflammation. In severe cases the body's immune response and cell damage leads to the hallmark pseudomembranes seen in PMC [5].
Not all antibiotic therapy is created equal, but broad spectrum agents like clindamycin, cephalosporins and fluoroquinolones are often implicated. These drugs wipe out a wide range of gut flora making room for C. difficile to flourish [10].
PMC symptoms often start during or shortly after antibiotics:
These symptoms can overlap with other conditions but the timing, especially after antibiotics, is a key clue.
PMC doesn't affect everyone the same way. While some people have mild diarrhea others can spiral into severe colitis and complications like:
These cases need urgent medical attention.
Healthcare providers consider PMC when a patient on antibiotics develops sudden or worsening diarrhea, so rapid diagnosis is key. But diagnosing it isn't always easy.
Metronidazole: Metronidazole is used for mild to moderate PMC. It's effective, cheap and oral [1], [8]. But it's being replaced by other treatments due to higher relapse rates and slower symptom resolution.
Vancomycin: Oral vancomycin is now the go to for severe or complicated C. difficile infections. It stays in the gut (where it's needed) without being absorbed into the bloodstream so it targets the infection locally.
PMC relapses so recurrent Clostridioides difficile infection is common. Some patients may need extended vancomycin tapers, fidaxomicin (a newer antibiotic) or even fecal microbiota transplantation (FMT).
FMT involves restoring healthy gut bacteria by transplanting stool from a donor—a treatment that's showing promising results in recurrent Clostridioides difficile infection cases [4].
One of the best ways to prevent PMC is smart antibiotic prescribing. Avoiding unnecessary prescriptions especially broad spectrum antibiotics can help preserve the natural gut microbiome and prevent C. difficile overgrowth.
Hospitals and healthcare facilities also have a role to play by enforcing infection control measures such as hand hygiene and isolation protocols to limit the spread of C. difficile spores.
Pseudomembranous colitis is more than just a complication of antibiotic use—it's a serious gastrointestinal illness that needs timely diagnosis and treatment. Understanding the underlying disruption of gut microbiota and toxin production is key to managing and preventing this condition. As we learn more about PMC the emphasis remains on prevention through good antibiotic stewardship and early intervention when symptoms occur.

Dartmouth Hitchcock Medical Center's safety grade dropped from an ‘A' to a ‘C,' per new report
The spring 2024 Center in Lebanon, dropped from an 'A' to a 'C.' Get N.H. Morning Report A weekday newsletter delivering the N.H. news you need to know right to your inbox. Enter Email Sign Up On infections, it found DHMC performed worse than average when it came to rates of sepsis infection after surgery and C. difficile infection. The hospital also lost points on issues related to surgery, such as surgical wounds splitting open, blood leakage, kidney injury after surgery, and accidental cuts and tears. Advertisement Michael S. Calderwood, the chief quality officer at DHMC, said Dartmouth Health has robust quality and safety standards to ensure that patients experience the highest-quality care. 'Voluntary data submissions to groups like Leapfrog are nuanced and don't always capture the full picture of safety ratings,' he said in an email. He added that in the latest Leapfrog report DHMC maintained or improved performance in all areas except four. Advertisement Calderwood said the hospital has made improvements on managing infections since the 2023-2024 data reflected in the latest Leapfrog report. He said a hospital task force has worked on infections caused by catheters, " The Leapfrog safety report found DHMC was also below average on handwashing. But Calderwood said the report's methodology relies heavily on automated hand hygiene data, which he said is unreliable and lacks the opportunity for 'in-the-moment' education. These automated systems include technology like Calderwood said DHMC is using direct observation instead of the automated system, but that has impacted the Leapfrog methodology for data collection. 'Recognizing that we have already driven significant improvement in a number of the key areas identified in the Leapfrog survey and beyond, we see our Spring 2025 score as an opportunity to focus on areas for improvement,' he said. The New Hampshire hospitals that received the highest safety grade include Wentworth-Douglass Hospital in Dover, Exeter Hospital, Portsmouth Regional Hospital, and St. Joseph Hospital in Nashua. Both Catholic Medical Center and Cheshire Medical Center received a 'D' grade, the lowest safety grade assigned to any hospital in the state. A spokesperson for Cheshire Medical Center said the hospital has chosen not to participate in the Leapfrog survey and that the grade does not accurately reflect the safety and quality of care provided to patients. Advertisement 'Cheshire has been notified from the Centers for Medicare & Medicaid Services' annual Preview Report that it will be awarded four stars, up from three stars last year,' the spokesperson said. Facing serious financial problems, Catholic Medical Center was CMC was the subject of a 'CMC did not participate in the Leapfrog survey prior to joining HCA Healthcare earlier this year, which means the current grade is based on limited historical information,' a spokesperson for the hospital said in a statement. 'HCA Healthcare has a strong and continuous commitment to measuring quality and safety in patient care,' the statement said. 'We are actively integrating our comprehensive quality and safety programs at CMC.' On the latest safety report for other HCA-owned hospitals, Parkland Medical Center received a 'B,' while Frisbie Memorial Hospital received a 'C.'
