Recurrent C. difficile or Ulcerative Colitis flare?

A case of a 24yo woman with rapidly progressive ulcerative colitis and recurrent C. dif was presented. We reviewed how to diagnose C. dif (ELISA vs. PCR vs. culture) and available treatments, including a new antibiotic fidaxomicin. ISDA guidelines were also reviewed. Cost of various treatment regimens were mentioned: metronidazole course ~$100; vancomycin course ~$200; fidaxomicin course ~$3000!
