Simultaneous assays for Clostridium difficile and faecal lactoferrin in ulcerative colitis.
Infectious agents may be one of the important factors in initiating or perpetuating ulcerative colitis. Increasing evidence has accumulated regarding the role of Clostridium difficile (C. difficile) infection in the exacerbation of ulcerative colitis. The present work was undertaken to study the implications of C. difficile toxin (CDT) and faecal lactoferrin (FL) positivity in patients with idiopathic ulcerative colitis (IUC) in a north Indian hospital. Ninety-four faecal samples from patients of IUC were processed for CDT and FL simultaneously. Clinical details of patients, including antibiotic intake in the past 6 weeks, were recorded. Eighty-one of the 94 patients (86.2%) had diarrhoea and 48 (51.1%) had received antibiotics. There was a statistically significant (p < 0.001) increase in the prevalence of diarrhoea among individuals receiving antibiotics. Twelve of the 94 samples (12.8%) were CDT positive while 16 were FL positive. No statistical significance (p > 0.05) was seen while comparing the positivity of CDT and FL in relation to the receipt of antibiotics. A statistically significant (p < 0.001) positive correlation was present between CDT and FL assays. FL positivity in IUC may depend on the intestinal inflammation precipitated by C. difficile infection.
