Guery B, et al. - Researchers performed a comparison of clinical outcomes of extended-pulsed fidaxomicin with standard vancomycin for Clostridium difficile infection in patients 60 years and older. Compared to standard-dose vancomycin, extended-pulsed fidaxomicin proved superior for sustained cure of C difficile infection. As per them, extended-pulsed fidaxomicin recurrence rates in this study were the lowest observed in a randomised clinical trial of antibiotic treatment for C difficile infection.
