Probiotics for NEC -More Work is Needed (part 2)

Posted on by

For very low birth weight (VLBW) premature infants, there is even more evidence that probiotics are effective (The Journal of Pediatrics Volume 165, Issue 2 , Pages 285-289.e1, August 2014 -thanks to Kipp Ellsworth for abstract link).

Abstract ():

Study design

Within the observational period (September 1, 2010, until December 31, 2012, n = 5351 infants) study centers were categorized into 3 groups based on their choice of Lactobacillus acidophilus/Bifidobacterium infantis use: (1) no prophylactic use (12 centers); (2 a/b) change of strategy nonuser to user during observational period (13 centers); and (3) use before start of observation (21 centers). 

Results

The use of probiotics was associated with a reduced risk for necrotizing enterocolitis surgery (group 1 vs group 3: 4.2 vs 2.6%,P = .028; change of strategy: 6.2 vs 4.0%, P < .001), any abdominal surgery, and hospital mortality. Infants treated with probiotics had improved weight gain/day, and probiotics had no effect on the risk of blood-culture confirmed sepsis. In a multivariable logistic regression analysis, probiotics were protective for necrotizing enterocolitis surgery (OR 0.58, 95% CI 0.37-0.91; P = .017), any abdominal surgery (OR 0.7, 95% CI 0.51-0.95; P = .02), and the combined outcome abdominal surgery and/or death (OR 0.43; 95% CI 0.33-0.56; P < .001).

The Time for a Confirmatory NEC Probiotic Prevention Trial in ELBW Infants is Now. Editorial in J Peds  (The Journal of Pediatrics
Volume 165, Issue 2 , Pages 389-394, August 2014)

This editorial reviews previous studies and recommends implementing a Probiotic Trial in North America. Here’s an excerpt:

“An adequately powered double-blinded placebo-controlled trial replicating a previous effective NEC prevention study in VLBW infants was published (the ProPrem trial)…the study revealed a significant reduction of NEC: from 4.4%-2.0% but no effect on mortality (4.9% vs 5.1%)…A closer look at the results of the ProPrem study, however, reveals that the probiotic supplementation did not have any effect on NEC in the ELBW (<1000 g) infants, which is consistent with two small previous studies reporting data on these infants separately.36, 42 Thus, there is currently no compelling evidence for recommending prophylactic probiotics to prevent NEC in infants with a birth weight <1000 g. Especially important is the lack of safety information in these most immature and highly vulnerable babies…Probiotics appear promising for use as prevention strategy for NEC, but there is still insufficient data for general recommendation of the use of probiotics in the ELBW infant. We argue, therefore, that now is the time to conduct in the North American setting, a high quality confirmative NEC prevention trial using probiotics in at-risk ELBW infants.”
