Barbut F, et al. - Researchers here determined the utility of quantifying faecal lactoferrin and calprotectin concentrations in Clostridium difficile infection (CDI) patients with or without free toxins in the stools. Findings revealed that in patients with CDI, both faecal calprotectin and lactoferrin were higher. This was particularly evident in those with detectable toxin in faeces. Thus suggesting a correlation between intestinal inflammation and toxins in stools.
