    Input: 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 & 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 Objective : To evaluate the efficacy of probiotics in the prevention of gastrointestinal colonization by C and ida species , of late-onset sepsis and neurological outcome in preterm newborns . Study Design : A prospect i ve study was conducted in 249 preterms who were subdivided into three groups :  one group ( n=83 ) was supplemented with Lactobacillus ( L. ) reuteri , one group with L. rhamnosus ( n=83 ) and the other with no supplementation ( n=83 ) . The fungal colonization in the gastrointestinal tract , the late onset of sepsis and clinical parameters were recorded . A neurological structured assessment was further performed at 1 year of age . Result : C and ida stool colonization was significantly higher ( P<0.01 ) in the control group than in the groups treated with probiotics . The L. reuteri group presented a significantly higher reduction in gastrointestinal symptoms than did the L. rhamnosus and control groups . Infants treated with probiotics showed a statistically significant lower incidence of abnormal neurological outcome than did the control group . Conclusion : The use of both probiotics seems to be effective in the prevention of gastrointestinal colonization by C and ida , in the protection from late-onset sepis and in reducing abnormal neurological outcomes in preterms BACKGROUND AND OBJECTIVE : It has been suggested that probiotics may decrease  infant mortality and nosocomial infections because of their ability to suppress colonization and translocation of bacterial pathogens in the gastrointestinal tract . We design ed a large double-blinded placebo-controlled trial using Lactobacillus reuteri to test this hypothesis in preterm infants . METHODS : Eligible infants were r and omly assigned during the first 48 hours of life to either daily probiotic administration or placebo .  Infants in the intervention group were administered enterally 5 drops of a probiotic preparation containing 108 colony-forming units of L reuteri DSM 17938 until death or discharge from the NICU . RESULTS : A total of 750 infants ≤2000 g were enrolled . The frequency of the primary outcome , death , or nosocomial infection , was similar in the probiotic and placebo groups ( relative risk 0.87 ; 95 % confidence interval : 0.63–1.19 ; P = .376 ) . There was a trend toward a lower rate of nosocomial pneumonia in the probiotic group ( 2.4 % vs 5.0 % ; P = .06 ) and a nonsignificant 40 % decrease in necrotizing enterocolitis ( 2.4 % vs 4.0 % ; P = .23 ) . Episodes of feeding intolerance and duration of hospitalization were lower in infants ≤ 1500 g ( 9.6 % vs 16.8 % [ P = .04 ] ; 32.5 days vs 37 days [ P = .03 ] ) . CONCLUSIONS : Although L reuteri did not appear to decrease the rate of the composite outcome , the trends suggest a protective role consistent with what has been observed in the literature . Feeding intolerance and duration of hospitalization were decreased in premature infants ≤1500 Background : Nosocomial infections endanger preterm infants . Objective : The aim of the present controlled r and omized trial was to investigate whether Bifidobacterium lactis reduces the incidence of nosocomial infections in infants with very low birth weight ( VLBW ; < 1,500 g ) < 30 weeks of gestation . Patients and Methods : In a r and omized controlled trial , 183 VLBW infants < 30 weeks of gestation were stratified according to gestational age ( 23–26 and 27–29 weeks ) and early antibiotic therapy ( days 1–3 , yes or no ) and r and omly assigned to have their milk feedings supplemented with B. lactis ( 6 × 2.0 × 109 CFU/kg/day , 12 billion CFU/kg/day ) or placebo for the first 6 weeks of life . Primary outcome was the ‘ incidence density ’ of nosocomial infections defined as periods of elevated C-reactive protein ( > 10 mg/l ) from day 7 after initiation of milk feedings until the 42nd day of life ( number of nosocomial infections/total number of patient days ) . The main secondary outcome was necrotizing enterocolitis ( NEC ; ≧stage 2 ) . Results : There were 93 infants in the B. lactis group and 90 in the placebo group . There was no significant difference between the two groups with regard to the incidence density of nosocomial infections ( 0.021 vs. 0.016 ; p = 0.9 , χ2 test ) . There were 2 cases of NEC in the B. lactis group and 4 in the placebo group . None of the blood cultures grew B. lactis . Conclusion : In the present setting , B. lactis at a dosage of 6 × 2.0 × 109 CFU/kg/day ( 12 billion CFU/kg/day ) did not reduce the incidence density of nosocomial infections in VLBW infants . No adverse effect of B. lactis was observed BACKGROUND AND OBJECTIVE : Late-onset sepsis frequently complicates prematurity , contributing to morbidity and mortality . Probiotics may reduce mortality and necrotizing enterocolitis ( NEC ) in preterm infants , with unclear effect on late-onset sepsis . This study aim ed to determine the effect of administering a specific combination of probiotics to very preterm infants on culture-proven late-onset  sepsis . METHODS : A prospect i ve multicenter , double-blinded , placebo-controlled , r and omized trial compared daily administration of a probiotic combination ( Bifidobacterium infantis , Streptococcus thermophilus , and Bifidobacterium lactis , containing 1 × 109 total organisms ) with placebo ( maltodextrin ) in infants born before 32 completed weeks ’ gestation weighing < 1500 g. The primary outcome was at least 1 episode of definite late-onset sepsis . RESULTS : Between
