Pakarinen et al., on the other hand, noted similar CRP levels in 15 patients with elevated fecal calprotectin compared to 17 with normal calprotectin levels.18 In a recent study by Ollech et al., CRP was compared to fecal calprotectin as a marker for pouch inflammation in a cohort of 156 patients with IPAA.19 The authors found that median CRP values were higher in patients with pouchitis compared to patients without pouchitis. The gene discussed is CRP; the disease is pouchitis.
