Best treatments for pseudomembranous enterocolitis

Understanding pseudomembranous enterocolitis

"Enterocolitis, Pseudomembranous" is the MeSH heading for what clinicians call pseudomembranous colitis. MedlinePlus (NLM) defines it as "swelling or inflammation of the large intestine (colon) due to an overgrowth of Clostridioides difficile bacteria," typically after antibiotics have thinned the gut flora that keep C. diff in check; the bacteria then "give off a strong toxin that causes inflammation and bleeding in the lining of the colon." The name describes what a colonoscope sees — StatPearls (NCBI Bookshelf) reports raised yellowish, sometimes hemorrhagic plaques up to 2 cm across, scattered among healthy-looking mucosa. StatPearls also lists other causes of the same picture (ischemic colitis, inflammatory bowel disease, CMV colitis, vasculitis, Behçet's disease, chemotherapy), so a pseudomembrane is a finding, not automatically a C. diff diagnosis. Two things people get wrong. First, testing: CDC clinical guidance says labs should test only unformed stool, and that laxatives should be discontinued with a 48-hour wait before testing. Second, and counterintuitively, CDC says that once a patient tests positive, you do not repeat testing to prove cure — tests can stay positive for six weeks or longer. Scale, per StatPearls: almost 500,000 episodes and 29,000 deaths a year in the US, roughly 20% relapse after treatment, and 3–8% progress to fulminant disease including toxic megacolon. This is general information, not medical advice — discuss your own case with a clinician.
