Probiotic Prophylaxis in Predicted Severe Acute Pancreatitis: A Randomised, Double-Blind, Placebo-Controlled Trial

Background: Infectious complications and associated mortality are
a major concern in acute pancreatitis. Enteral administration of probiotics
could prevent infectious complications, but convincing evidence is scarce. Our
aim was to assess the effects of probiotic prophylaxis in patients with
predicted severe acute pancreatitis. Methods: In this multicenter
randomized, double-blind, placebo-controlled trial, 298 patients with
predicted severe acute pancreatitis (Acute Physiology and Chronic Health
Evaluation [APACHE II] score 8, Imrie score 3, or C-reactive protein
>150 mg/L) were randomly assigned within 72 h of onset of symptoms to
receive a multispecies probiotic preparation (n = 153) or placebo (n = 145),
administered enterally twice daily for 28 days. The primary endpoint was the
composite of infectious complications—i.e., infected pancreatic
necrosis, bacteremia, pneumonia, urosepsis, or infected ascites—during
admission and 90-day follow-up. Analyses were by intention to treat. This
study is registered, number ISRCTN38327949. Findings: One person in
each group was excluded from analyses because of incorrect diagnoses of
pancreatitis; thus, 152 individuals in the probiotics group and 144 in the
placebo group were analysed. Groups were much the same at baseline in terms of
patients' characteristics and disease severity. Infectious complications
occurred in 46 (30%) patients in the probiotics group and 41 (28%) of those in
the placebo group (relative risk 1.06, 95% CI 0.75–1.51). 24 (16%)
patients in the probiotics group died, compared with nine (6%) in the placebo
group (relative risk 2.53, 95% CI 1.22–5.25). Nine patients in the
probiotics group developed bowel ischaemia (eight with fatal outcome),
compared with none in the placebo group (p = 0.004). Interpretation:
In patients with predicted severe acute pancreatitis, probiotic prophylaxis
with this combination of probiotic strains did not reduce the risk of
infectious complications and was associated with an increased risk of
mortality. Probiotic prophylaxis should therefore not be administered in this
category of patients. (Lancet. 2008;371(9613):651-659)
