    Input: OBJECTIVE The use of probiotics is increasingly popular in preterm neonates , as they may prevent necrotizing enterocolitis sepsis and improve growth and feeding tolerance . There is only limited literature on Saccharomyces boulardii CNCM I-745 ( S. boulardii ) in preterm infants . METHOD A prospect i ve , r and omized , case-controlled trial with the probiotic S. boulardii ( 50mg/kg twice daily ) was conducted in newborns with a gestational age of 30 - 37 weeks and a birth weight between 1500 and 2500 g . RESULTS 125 neonates were enrolled ; 63 in the treatment and 62 in the control group . Weight gain ( 16.14±1.96 vs. 10.73±1.77g/kg/day , p<0.05 ) and formula intake at maximal enteral feeding ( 128.4±6.7 vs. 112.3±7.2mL/kg/day , p<0.05 ) were significantly higher in the intervention group . Once enteral feeding was started , the time needed to reach full enteral feeding was significantly shorter in the probiotic group ( 0.4±0.1 vs. 1.7±0.5 days , p<0.05 ) . There was no significant difference in sepsis . Necrotizing enterocolitis did not occur . No adverse effects related to S. boulardii were observed . CONCLUSION Prophylactic supplementation of S. boulardii at a dose of 50mg/kg twice a day improved weight gain , improved feeding tolerance , and had no adverse effects in preterm infants > 30 weeks old UNLABELLED The aim of the study is to compare the role of killed ( KP ) Lactobacillus acidophilus with living ( LP ) in reducing incidence of sepsis ( NS ) and necrotizing enterocolitis ( NEC ) in neonates . R and omized double blind placebo study , included 150 neonates admitted to NICU at day 1 , sixty received oral ( LP ) and 60 received ( KP ) and 30 received placebo .  One gram of stools was collected on admission , at day 7 , at end of the study , as well as on suspected NEC or NS and was sent for culture . RESULTS LP and KP were preventive factors for NEC with absolute risk reduction ( AAR ) 16 , 15 % , respectively and 18 % for NS compared to placebo .  Incidence of NEC and NS did not differ significantly between neonates supplemented with LP and those with KP . Preterm neonates supplemented with KP showed significantly lower incidence of NEC compared to placebo , while incidence of NS showed no significant difference between both groups . There is significant reduction in NS and NEC among neonates with positive Lactobacillus colonization of gut compared to those none colonized at day 7 ( 27.9 vs. 85.9 % , 0 vs. 7.8 % ) and at day 14 ( 48.7 vs. 91.7 % for NS and 0 vs. 20.8 % for NEC ) . Overall comparison between the three groups showed statistical significant reduction in the incidence of NEC . Present conclusions are that early gut colonization with beneficial bacteria lowers the incidence of NEC and NS . KP retained similar benefits to live bacteria Background : The increase in invasive fungal infections ( IFIs ) in neonatal intensive care unit ( NICU ) is jeopardizing the survival of preterm neonates . Probiotics modulating the intestinal microflora of preterm neonates may minimize enteral fungal colonization . Aims : This study was to examine whether probiotic supplementation in neonates reduced fungal septicemia . Material s and Methods : This prospect i ve , r and omized , double blind trial investigating the  supplementation of preterm infants with a probiotic  was done from May 2012 to April 2013 , with 112 subjects r and omized into two groups . Primary outcome : Decreased fungal colonization in gastrointestinal tract . Others : Incidence of late onset septicemia ; duration of the primary hospital admission ; number of days until full enteral feeds established . Results : Full feed establishment was earlier in probiotics group compared to placebo group ( P = 0.016 ) . The duration of hospitalization was less in the probiotic group ( P = 0.002 ) . Stool fungal colonization , an important outcome parameter was 3.03 ± 2.33 × 105 colony formation units ( CFU ) in the probiotics group compared to 3 ± 1.5 × 105 CFU in the placebo group ( P = 0.03 ) . Fungal infection is less in the study group ( P = 0.001 ) . Conclusion : The key features of our study were reduced enteral fungal colonization , reduce invasive fungal sepsis , earlier establishment of full enteral feeds , and reduced duration of hospital stay in the probiotics group BACKGROUND Probiotics are used for the prevention of necrotizing enterocolitis ( NEC ) because of their positive effects on intestinal motor function , modulation of inflammatory response , and mucosal barrier function . OBJECTIVE The objective was to assess whether the combined use of Lactobacillus casei and Bifidobacterium breve may prevent the occurrence of NEC stage ≥ 2 by the criteria of Bell in very-low-birth-weight preterm infants . DESIGN A double-blind , r and omized , controlled clinical trial was conducted in 231 preterm infants weighing from 750 to 1499 g at birth . The intervention group was composed of 119 infants who received human milk with probiotic supplementation ( B. breve and L. casei )  and a control group of 112 infants who received human milk containing no probiotics .  The primary outcome was the occurrence of NEC stage ≥ 2 as defined by Bell 's modified criteria . RESULTS Four confirmed cases of NEC stage ≥ 2 by Bell 's criteria occurred only in the control group . CONCLUSIONS Oral supplementation of B. breve and L. casei reduced the occurrence of NEC ( Bell 's stage ≥ 2 ) . It was considered that an improvement in intestinal motility might have contributed to this result . This trial was registered at www.is rct in.org as number 67165178 ( International St and ard R and omized Controlled Trial ) BACKGROUND & AIMS Recent studies have suggested that the gut microflora has metabolic effects . We aim ed to evaluate postnatal growth in preterm infants who received different probiotic supplements  , and to assess the safety of probiotic administration . METHODS This prospect i ve , r and omized , double-blind , controlled trial was performed at three tertiary care neonatal units . Preterm infants were r and omly assigned to receive daily supplementation over 4 - 6 weeks with placebo ( group C ) or probiotics ( group P ) . Group P comprised three subgroups : P1 received Bifidobacterium lactis , P2 received Bifidobacterium longum , and P3 received B. lactis and B. longum . We assessed postnatal growth during the supplementation period and up to a corrected gestational age ( GA ) of 41 weeks when body composition was assessed using whole-body dual-energy X-ray absorptiometry . Aerobic and anaerobic blood cultures were performed on suspicion of late-onset sepsis . RESULTS The study comprised 199 preterm infants with a mean GA of 29.1 ± 1.4 weeks and a mean birth weight of 1173 ± 210 g , who received a placebo  ( group C , n = 52 )  or probiotics  ( group P , n = 147 ) from the first week of life . At the end of the supplementation period , no statistically significant differences were seen between the groups in relation to the mean body weight ( group C = 1906 ± 23 g , group P = 1875 ± 14 g , p = 0.25 ) , length , or head circumference . The incidence rates of necrotizing enterocolitis and late-onset sepsis were similar in the two groups . At the corrected GA of 41 weeks , there were no differences between the groups with respect to anthropometric measurements or body composition analysis . CONCLUSIONS Preterm infants receiving  Bifidobacterium supplements did not exhibit better postnatal growth compared with those who received placebo treatment . No adverse effects were associated with probiotic administration . Registered under Clinical Trials.gov Identifier no. NCT01379417 BACKGROUND Probiotics have strain specific effects and the effects of fungi in preventing diseases in preterm infants have been investigated poorly . Saccharomyces boulardii is a yeast which acts both as a probiotic and a polyamine producer . AIM The objective of this study was to investigate the efficacy of S. boulardii in preventing necrotizing enterocolitis ( NEC ) or sepsis in very low birth weight infants . STUDY DESIGN AND SUBJECTS A prospect i ve , double blind , placebo controlled trial was conducted in preterm infants ( ≤ 32 GWs , ≤ 1500 g birth weight ) . They were r and omized either to receive feeding supplementation with S. boulardii 50 mg/kg every 12 h or placebo , starting with the first feed until discharged . OUTCOME MEASURES Necrotizing enterocolitis ( NEC ) or sepsis and NEC or death . RESULTS Birth weight and gestational age of the study ( n = 104 ) and the control ( n = 104 ) groups were 1126 ± 232 vs 1162 ± 216 g and 28.8 ± 2.2 vs 28.7 ± 2.1 weeks , respectively . Neither the incidence of stage ≥ 2 NEC or death nor stage ≥ 2 NEC or late onset culture proven sepsis was significantly lower in the study group when compared with the control group ( 9.6 % vs 7.7 % , p = 0.62 ; 28.8 % vs 23 % , p = 0.34 ) . Time to reach 100 mL/kg/day of enteral feeding ( 11.9 ± 7 vs 12.6 ± 7 days , p = 0.37 ) was not different between the groups . CONCLUSIONS Saccharomyces boulardii did not decrease the incidence of NEC or sepsis ABSTRACT The gastrointestinal microbiota of preterm infants in a neonatal intensive care unit differs from that of term infants . In particular , the colonization of preterm infants by bifidobacteria is delayed . A double-blind , placebo-controlled , r and omized clinical study was performed on 69 preterm infants to investigate the role of Bifidobacterium lactis Bb12 supplementation in modifying the gut microbiota . Both culture-dependent and culture-independent approaches were used to study the gut microbiota . Bifidobacterial numbers , determined by fluorescence in situ hybridization , were significantly higher in the probiotic than in the placebo group ( log10 values per g of fecal wet weight : probiotic , 8.18 + 0.54 [ st and ard error of the mean ] ; placebo , 4.82 + 0.51 ; P < 0.001 ) . A similar trend for bifidobacterial numbers was also obtained with the culture-dependent method . The infants supplemented with Bb12 also had lower viable counts of Enterobacteriaceae ( log10 values of CFU per g of fecal wet weight : probiotic , 7.80 + 0.34 ; placebo , 9.03 + 0.35 ; P = 0.015 ) and Clostridium spp . ( probiotic , 4.89 + 0.30 ; placebo , 5.99 + 0.32 ; P = 0.014 ) than the infants in the placebo group . Supplementation of B. lactis Bb12 did not reduce the colonization by antibiotic-resistant organisms in the study population . However , the probiotic supplementation increased the cell counts of bifidobacteria and reduced the cell counts of enterobacteria and clostridia BACKGROUND It is known that the bifidobacteria flora play important roles in mucosal host defense and can prevent infectious diseases . Because bacterial population s develop during the first day of life , the authors examined whether the early administration of bifidobacteria has a positive effect on the health of low birth weight infants . METHODS The effects of oral administration of Bifidobacterium breve ( B. breve ) supplements were studied in a controlled trial with low birth weight infants ( average birth weight 1489 g ) . The infants were divided into three groups : Group A and B received a dose of 1.6 x 10(8 ) cells of B. breve supplement twice a day , commencing either from several hours after birth ( group A ) or 24 h after birth ( group B ) . Group C , the control group , received no supplement . RESULTS There were no significant differences in birth weight , treatment with antibiotics , and the starting time of breast-feeding among the three groups . A Bifidobacterium-predominant flora was formed at an average of 2 weeks after birth in group A and at an average of 4 weeks after birth in group B , while no Bifidobacterium was isolated in eight out of 10 infants in group C during the observation period of 7 weeks . In comparison between group A and B , Bifidobacterium was detected significantly earlier in group A , and the number of Enterobacteriaceae present
