Antibiotic-associated diarrhea (AAD) frequently complicates treatment of infections. A recent randomized, double-blind, placebo-controlled trial tested a proprietary probiotic mixture and found that it reduced the incidence of AAD by 16%. This is encouraging for patients, but future progress on prob …

The rapid increase in microbial antibiotic resistance in Clostridioides difficile (C. difficile) strains and the formation of hypervirulent strains have been associated with a global increase in the incidence of C. difficile infection (CDI) and subsequently, an increase in the rate of recurrence. Th …

Colitis is associated with many diseases, and treatment depends on the exact cause.

Dr David Johnson highlights studies on increasing disease rates, the surprising effects of palliative care consultations, and drugs on the verge of approval.

Taking probiotics with antibiotics can help protect the gut from the negative effects of antibiotics. But some people may benefit from it more than others.

PHILADELPHIA — Rebyota was safe and effective at 8 weeks and up to 6 months in patients with recurrent Clostridioides difficile infection, many of whom had other gastrointestinal comorbidities and risk factors, according to data presented. “We showed a significant decrease in recurrence rates of Clostridioides difficile in a real-world population,” Timothy E. Ritter, MD, a

Clostridioides difficile is an anaerobic, spore-forming, Gram-positive pathogen responsible for various conditions from mild diarrhea to severe toxic megacolon and potentially death. Current treatments for C. difficile infection (CDI) rely on antibiotics like vancomycin and metronidazole (MTZ); however, the high doses required often disrupt gut microbiota, leading to a high recurrence rate. Mitomycin C (MMC), a chemotherapy drug approved by the FDA, is known for inducing phage production in lysogenic bacterial strains, effectively targeting the host bacteria. Given that 70% of C. difficile strains harbor prophages, this study investigates MMC's potential to enhance antibiotic efficacy against CDI. Our in vitro experiments indicate that MMC acts synergistically with MTZ to inhibit the growth of C. difficile strain R20291. Furthermore, this combination decreases biofilm-resident vegetative cell resistance and reduces the MTZ concentration needed to kill C. difficile in stool samples ex vivo. In a CDI mouse relapse model, in vivo results show that MMC combined with a low dose of MTZ significantly improves survival rates and reduces fecal spore counts after antibiotic treatment. Overall, these findings suggest that a low-dose combination of MMC and MTZ offers enhanced therapeutic efficacy for CDI, both in vitro and in vivo, and may provide a promising new approach for treatment. ### Competing Interest Statement The authors have declared no competing interest.

Clostridioides difficile and mortality in Hidradenitis Suppurativa patients: a retrospective cohort study

Recurrent CDI occurred in 10% of HCT recipients in the early posttransplant period and was associated with use of metronidazole. Further study is needed to characterize risk factors for recurrent CDI among HCT recipients to guide use of agents aimed at preventing recurrence.

In elderly IBD patients hospitalized for IBD flare and subsequently discharged, a concurrent CDI infection was not associated with post-discharge IBD-related complications or mortality up to 1-year.

Comprehensive strategies are needed to treat and prevent C. difficile infection, which is a significant contributor to morbidity across the general population.

Metronidazole compared to vancomycin for treatment of mild to moderate CDI in IBD is effective however may be associated with higher rates of treatment failure.

Penn Medicine and the Children’s Hospital of Philadelphia have developed the first mRNA vaccine against C. difficile to successfully ward off the bacterial infection.
