LTF and pouchitis: In a subset of 16 patients with pouchitis, treatment with a three-week course of metronidazole was described, with appropriate reduction in stool excretion of fecal A1AT in follow-up; however, the exact data from these assessments are not reported.47 Similarly, in a subset of seven patients, Gonsalves et al. reported an improvement in lactoferrin level that correlated with clinical improvement as assessed by the clinical PDAI following a course of antibiotics.
