Reduction of crying episodes owing to infantile colic: A randomized controlled study on the efficacy of a new infant formula.

OBJECTIVES: The aim of this study was to evaluate the efficacy on crying episodes owing to infantile colic of a new infant formula containing partially hydrolysed whey proteins, prebiotic oligosaccharides (OS), with a high beta-palmitic acid content. DESIGN: Prospective randomized controlled study. SETTING: Italy. SUBJECTS: Two hundred and sixty-seven formula-fed infants, aged less than 4 months, with infantile colic, were randomized to receive either the new infant formula (study treatment (ST)) or a standard formula and simethicone (6 mg/kg twice a day) (control treatment (CT)). A questionnaire was given to parents to evaluate for 14 days the daily number of colic episodes and crying time. RESULTS: Out of the 199 infants who completed the study, 96 were treated with the new formula and 103 were not treated. Infants receiving the new formula had a significant decrease in colic episodes after 1 week (2.47+/-1.94 at day 7 vs 5.99+/-1.84 at the study entry) compared to infants receiving the CT (3.72+/-1.98 at day 7 vs 5.41+/-1.88 at the study entry) (P < 0.0001). Also at day 14, the crying episodes were significantly different between the two groups of infants (1.76+/-1.60 in ST vs 3.32+/-2.06 in CT) (P < 0.0001). CONCLUSIONS: The use of a partially hydrolysed formula supplemented with fructo- and galacto-OS induces a reduction of crying episodes in infants with colic after 7 and 14 days when compared with a standard formula and simethicone.

Relationship between gastro-oesophageal reflux and gastric activity in newborns assessed by combined intraluminal impedance, pH metry and epigastric impedance.

The pathogenesis of gastro-oesophageal reflux disease (GORD) is complex and multifactorial. A motility disorder resulting from immaturity of the gastro-oesophageal tract may be involved. We have combined multichannel intraluminal impedance (MII) and pH monitoring with epigastric impedance (EGI) to evaluate the activity of this tract in neonates with suspected GORD. Multichannel intraluminal impedance, pH and EGI were followed for 3 h in 30 newborns displaying apparent life-threatening events and signs of GORD. Simultaneous application of MII and pH monitoring identifies reflux episodes and illustrates their duration, height and pH. Episodes detected by MII were placed on the EGI curve and the contemporaneous gastric filling state and emptying velocity were calculated. During the total measuring time, 248 reflux episodes were revealed. An inverse correlation was evident for reflux frequency and gastric emptying velocity (r2 = 0.94; P < 0.001), and between acid refluxes and the gastric filling state (r2 = 0.95; P < 0.001), whereas a positive correlation was found between the reflux level and the gastric filling state (r2 = 0.52; P < 0.05). Simultaneous MII, pH and EGI monitoring provided new information on the relationship between refluxes and gastric activity. Data suggest that gastric emptying patterns influence the frequency, level and pH of reflux episodes.

The Biagram vector: a graphical relation between reactance and phase angle measured by bioelectrical analysis in infants.

BACKGROUND: Biagram vector is derived by plotting direct measurements of reactance and phase angle from the analyzer, which are not dependent on anthropometric characteristics of the subject and it can be considered an emerging method for evaluating the nutritional status in clinical practice. AIM: To calculate and plot the Biagram vector in a sample of healthy infants in their first year of life. METHODS: 174 healthy infants (99 male, 75 female) aged under 1 year, born at full term and adequate for gestational age, were enrolled in a cross-sectional study. The sample was divided into three age groups: 0-3.99 months (group A), 4-7.99 months (group B), and 8-11.99 months (group C). Bioelectric impedance analysis (BIA) was performed by a tetrapolar single frequence phase-sensitive impedance analyzer (STA/BIA; Akern Srl, Firenze, Italy). RESULTS: Biagram vector showed an increasing trend (p < 0.05) in the first year of life (group A: 27.9 +/- 12.6; group B: 32.1 +/- 9.7; group C: 37.2 +/- 9.5). Females showed Biagram vector values significantly higher than males in group A (34.7 +/- 15.0 vs. 24.0 +/- 9.1; p < 0.05). 95% confidence ellipses of Biagram vector for each age group were calculated and plotted and a comparison of our results with published data calculated in older children was conducted. CONCLUSION: The bivariate analysis of BIA measurements, plotted as a vector in relation to the age, showed an increasing trend with a higher gain rate under 1 year with respect to the following age periods. These data could reflect the variation of body composition in the first years of life and could be of interest to assess the nutritional status for clinical practice.

Gastric emptying in infants: epigastric impedance versus scintigraphy.

AIM: To compare epigastric impedance versus scintigraphy in monitoring the gastric emptying of the same adapted milk formula in infants. METHODS: Seven infants with clinical symptoms of gastric motility disease underwent scintigraphy with 99mTc sulphur colloid for the 90 min following the ingestion of the same adapted milk formula, in order to evaluate gastric emptying. A bio-impedance device, connected to a PC, was prepared for this purpose with four standard electrodes placed anteriorly on the upper part of the body. The obtained graphs were compared to those of the scintigraphic method. Statistical analysis was performed using Pearson correlation. The confidence limits were set at 95%. Parental consent was obtained before each analysis. RESULTS: The gastric emptying patterns obtained with epigastric impedance were closely correlated to those shown by the scintigraphy (r = 0.86 +/- 0.08; p < 0.05). A significant correlation between the gastric emptying velocity measured by the two techniques was found (r = 0.94; p = 0.002). CONCLUSIONS: Epigastric impedance in infants provided estimates of gastric emptying that were closely correlated with scintigraphy. However, the limits derived from the epigastric impedance suggest that, at the moment, the two methods should not be used interchangeably.

Intestinal microflora in breastfed colicky and non-colicky infants.

BACKGROUND: Infantile colics are a common problem in the first months of life. During this period, a process of intestinal colonization rapidly occurs. A difference in the gut microflora could play an important role in the pathogenesis of colics, changing the metabolism of carbohydrates and fatty acids. Actually, in the literature, only few data have been collected about this topic. In this study, we evaluated intestinal microflora in breastfed colicky and non-colicky infants. METHODS: Seventy-one breastfed infants, aged 3.2 +/- 0.6 wk, free from episodes of gastroenteritis and without previous assumption of antibiotic and probiotic drugs, were enrolled in the study. They were divided into two groups: colicky (42 cases) and non-colicky (29 cases), according to Wessel's criteria. Stool samples were collected, diluted and cultured on several selective media to detect lactobacilli, clostridia, gram-negative anaerobes and Enterobacteriaceae. Statistical analysis was performed using Student's t-test, chi2 test and a non-parametric test (Mann-Whitney U-test). RESULTS: Differences in gut microflora were found among colicky and non-colicky infants: colicky infants were less frequently colonized by Lactobacillus spp., and more frequently by anaerobic gram-negative bacteria. CONCLUSION: Our study indicates that colicky infants have different patterns of gut microflora. Further studies are required to understand whether gut microflora is the primary cause of colics or its consequence.

Infant nutritional recommendations from pediatricians. Epidemiologic survey of feeding recommendations for the first year of life in Piedmont.

AIM: Timing the introduction of solids and milk formulas in infants' diet varies throughout the world. The aim of the present study was to assess the modalities of weaning, suggested by pediatricians in Piedmont, Italy, and to compare them to current scientific guidelines. METHODS: The survey was conducted using data recording forms sent to the pediatricians of our area (both practitioners and hospital physicians) from September 2000 to January 2001. Pediatricians were asked to fill in a questionnaire about the time of solid food introduction in the 1st year of life. The study was supported by 168 pediatricians, of these 105 practitioners, 53 hospital doctors and 9 university physicians. RESULTS: The mean age of weaning was 4.5 months. The 1st beikost was vegetable soup with rice flour, meat and parmesan in 65.4%; in 73.8% it was given with a spoon. In 94.6% no salt was added, in 84.5% no sweetener was added. Homogenized fruit was introduced at a mean age of 4.4 months: apple was the 1st fruit to be introduced (4.5 months), followed by pear (4.8 months) and banana (5.6). Lyophilised meat was introduced at 5 months, homogenized meat was introduced at 6.2 months, and minced meat was introduced at 8.2 months. Vegetables (potatoes, carrots, courgettes) were introduced between 5.2 to 5.4 months of age. Parmesan was introduced at 5.3 months; gluten at 6.2 months. Egg yolk was the 1st to be introduced (mean age = 8.9 months), while albumen was introduced at a mean age of 11.6 months. Fish was given at a mean age of 8.2 months. Cow's milk was introduced at 9 months. CONCLUSION: Paediatricians give indications about the introduction of solid foods according to scientific guidelines, with the exception of cow's milk which is introduced too early.

"Minor" feeding problems during the first months of life: effect of a partially hydrolysed milk formula containing fructo- and galacto-oligosaccharides.

BACKGROUND: Colic, regurgitation and constipation are common feeding problems in formula-fed infants that might benefit from dietary treatment. A formula containing fructo- and galacto-oligosaccharides, partially hydrolysed proteins, low levels of lactose and palmitic acid in the beta position and higher density has been tested to reduce the occurrence of these symptoms. The aim of this prospective study was to describe the effects of such a formula in infants with minor gastrointestinal disorders. METHODS: An observational prospective trial involving practising Italian paediatricians was performed. Formula fed-infants up to 90 d of age with minor gastrointestinal problems such as infantile colics and/or regurgitation and/or constipation were enrolled in the study from January 2001 to May 2001. The study was completed within 14 d of treatment. On days 1, 7 and 14 the infants were visited by the paediatricians. Parents were given a structured diary to record daily episodes of colic, regurgitation and type and number of stools. RESULTS: Of the 932 infants enrolled, 604 completed the study. Of the 214 infants with colic, 169 (79%) demonstrated a reduction in frequency of colic from 4.1 +/- 2.0 per day at the beginning of the study to 2.0 +/- 1.8 at the end of the study (I.C. 95%: 1.72-2.39; p < 0.005). A reduction in the number of episodes of colic of 1.8 per day at the beginning of the study (I.C. 95%: 1.49-2.11; p < 0.05) was recorded between day 1 and day 7, and of 0.26 (I.C. 95%: 0.15-0.37; p < 0.05) between day 7 and day 14. Of the 201 infants with regurgitation problems, 141 (70%) demonstrated a reduction of frequency of the symptoms from 4.2 +/- 2.0 per day at the beginningof the study to 2.1 +/- 2.2 at the end of the study (I.C. 95%: 1.75-2.35; p < 0.005). A reduction of 1.87 in the number of regurgitation episodes was reported between day 1 and day 7 (I.C. 95%: 1.57-2.16; p < 0.05) and of 0.18 (I.C. 95%: 0.06-0.31; p < 0.05) between day 7 and day 14. Of the 232 infants with constipation, 147 (63%) demonstrated an increase in the daily number of stools of 0.42 (I.C. 95%: 0.5-0.3; p < 0.005). An increase in stool frequency of 0.41 (I.C. 95%: 0.51-0.23; p < 0.05) was reported between day 1 and day 7, and of 0.04 (I.C. 95%: 0.22-0.14; p = ns) between day 7 and day 14. Parents' evaluation of the formula was 7.9 +/- 1.8 (score 0-10); 550 parents (91%) gave a positive judgement (score > 6). The evaluation by the paediatricians of the improvement in symptoms after the treatment was 8.2 +/- 1.5; 574 (95%) a positive effect (score > 6). CONCLUSION: This study shows that the majority of infants followed by paediatricians for minor gastrointestinal symptoms improve within 2 wk of feeding with this new formula. Further double-blind, controlled studies are needed to confirm whether the amelioration of symptoms observed in this trial is in fact due to the new formula.
