Background and aims: Probiotics exert a beneficial effect on the host through modulation of gastrointestinal microflora. The aim of this study was to investigate the effect of the probiotic Lactobacillus plantarum 299v on gut barrier function and the systemic inflammatory response in critically M patients. Subjects and methods: One hundred and three critically M patients were randomised to receive an oral preparation containing L. plantarum 299v (ProViva) in addition to conventional therapy (treatment group, n = 52) or conventional therapy atone (control group, n = 51). Serial outcome measures included gastric cotonisation, intestinal permeability (lactulose/rhamnose dual-sugar probe technique), endotoxin exposure (IgM EndoCAb), C-reactive protein and Interteukin 6 levels. Results: L. plantarum had no identifiable effect on gastric colonisation, intestinal permeability, endotoxin exposure or serum CRP levels. There were no differences between the groups in terms of septic morbidity or mortality. On day 15 serum IL-6 levels were significantly tower in the treatment group compared to controls. Conclusions: The enteral administration of L. plantarum 299v to critically M patients was associated with a late attenuation of the systemic inflammatory response. This was not accompanied by any significant changes in the intestinal microflora, intestinal permeability, endotoxin exposure, septic morbidity or mortality. (c) 2004 Elsevier Ltd.
