There was no difference in mortality caused by NEC .
In premature newborns , the use of probiotics is effective as a prophylaxis for NEC and its complications
OBJECTIVE To eluci date the benefits of using probiotics in the prevention of  necrotizing enterocolitis ( NEC ) and its complications in preterm newborns .
A Randomized Placebo-controlled Comparison of 2 Prebiotic/Probiotic Combinations in Preterm Infants: Impact on Weight Gain, Intestinal Microbiota, and Fecal Short-chain Fatty Acids
Objective : To compare the effect of 2 prebiotic/probiotic products on weight gain , stool microbiota , and stool short-chain fatty acid ( SCFA ) content of premature infants . Patients and Methods : This r and omized , blinded , placebo-controlled trial included 90 premature infants treated with either a dietary supplement containing 2 lactobacillus species plus fructooligosaccharides ( CUL , Culturelle , ConAgra , Omaha , NE ) , a supplement containing several species of lactobacilli and bifidobacteria plus fructooligosaccharides ( PBP  , ProBioPlus DDS , UAS Laboratories , Eden Prairie , MN ) , or placebo ( a dilute preparation of Pregestamil formula ) twice daily for 28 days or until discharge if earlier . The primary outcome was weight gain . Secondary outcomes were stool bacterial analysis by culture and 16S rDNA quantitative polymerase chain reaction and stool SCFA content measured by high performance liquid chromatography . Results : Both prebiotic/probiotic combinations contained more bacterial species than noted on the label . No significant effect on infant growth of either prebiotic/probiotic supplement was observed . By cultures , 64 % of infants receiving PBP became colonized with bifidobacteria , compared with 18 % of infants receiving CUL and 27 % of infants receiving placebo ( chi-square , P = 0.064 ) . No differences were noted between groups in colonization rates for lactobacilli , Gram-negative enteric bacteria , or staphylococci . By 16S rDNA polymerase chain reaction analysis , the bifidobacteria content in the stools of the infants receiving PBP was higher than in the infants receiving CUL or placebo ( Kruskal-Wallis , P = 0.011 ) . No significant differences in stool SCFA content were detected between groups . No adverse reactions were noted . Conclusions : Infants receiving PBP were more likely to become colonized with bifidobacteria . No significant differences in weight gain or stool SCFA content were detected
