#CDI in #IBD compared to general 👩👨🦱
⬆️⬆️ common (5-8x 🔺)
⬆️ community-acquired
⬆️ w/o antibiotic 💊 exposure
⬆️ colonization
⬆️⬆️ recurrence ☹️
⬆️ colectomy risk 🔪
🚨 often no pseudomembranes on 🔦
🚨 can happen post-colectomy 🔪 in #smallbowel or #IPAA

Testing for #CDI ⬇️
💩 GDH:
✅ detects organism
⬆️ sensitive
⬇️ specific
💩 PCR:
✅ detects genes that code for toxin
🚫 detect toxin
⬆️ sensitive
⬆️ specific
🚨 can over-diagnose
💩 EIA for toxin A/B:
✅ detects toxin
⬆️ specific
⬇️ sensitive
🚨 can under-diagnose

🤔 about diagnosis?
🥇Start with ⬆️ sensitive test (GDH or PCR)
➖ not #CDI
➕ do ⬆️ specific test (toxin EIA)
🥈 Toxin EIA
➕ #CDI confirmed
➖ is 1/3 scenarios:
🟤 colonization
🟤 false ➖ toxin EIA
🟤 early infection
🤔 PCR if GDH ➕ and toxin EIA ➖
