Efficacy of donkey's milk in treating highly problematic cow's milk allergic children: An in vivo and in vitro study

Successful therapy in cows milk protein allergy rests on completely eliminating cows milk proteins from the childs diet: it is thus necessary to provide a replacement food. This prospective study investigated tolerance of donkeys milk in a population of 46 selected children with cows milk protein allergy, for whom it was not possible to use any cows milk substitute. Thirty‐eight children (82.6%) liked and tolerated donkeys milk at the challenge and for the entire duration of follow‐up. Catch‐up growth was observed in all subjects with growth deficit during cows milk proteins challenge. The degree of cross‐reactivity of immunoglobulin E (IgE) with donkeys milk proteins was very weak and aspecific. Donkeys milk was found to be a valid alternative to both IgE‐mediated and non‐IgE‐mediated cows milk proteins allergy, including in terms of palatability and weight‐height gain.

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 Wessels 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 Students t‐test, χ2 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.

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 β-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.Sponsorship:The study was supported by funds from Numico, Italy.

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 β 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).

Cimetropium bromide in the treatment of crisis in infantile colic

Background Treatment of infantile colic remains an open issue. In Italy, cimetropium bromide is used extensively to treat infantile colic. The aim of this randomized, double-blind, placebo-controlled clinical trial was to investigate the effectiveness and side effects of cimetropium bromide in the treatment of infants with colic crisis. Methods Ninety-seven infants with colic were enrolled. The diagnosis of infantile colic in healthy infants with regular growth, aged 15 to 60 days was made according to the criteria of Wessel. The infants were divided into two groups, one treated with cimetropium bromide (1.2 mg/kg) and the other treated with placebo at onset of each crisis for 3 days. Duration of crying and side effects were recorded daily in a structured diary for the 3 days of therapy. Statistical analysis was performed using the chi-square and t tests. Results Eighty-six infants completed the trial. The average duration of crying for each crisis was 17.3 ± 12.6 minutes in the cimetropium bromide group and 47.5 ± 28.5 minutes in the placebo group (P < 0.005). Response to cimetropium bromide was 74%. Response to placebo was 33% (P < 0.05). Side effects did not differ significantly between the two groups, except sleepiness, which increased in the infants treated with cimetropium bromide. Conclusion Cimetropium bromide was more effective than placebo in reducing the duration of crying in children with infantile colic. The use of the anticholinergic drugs, aside from the dicyclomine because of its dangerous side effects, should be revaluated for treating infantile colic.

The Effect of Holder Pasteurization on Nutrients and Biologically-Active Components in Donor Human Milk: A Review

When a mother’s milk is unavailable, the best alternative is donor milk (DM). Milk delivered to Human Milk Banks should be pasteurized in order to inactivate the microbial agents that may be present. Currently, pasteurization, performed at 62.5 °C for 30 min (Holder Pasteurization, HoP), is recommended for this purpose in international guidelines. Several studies have been performed to investigate the effects of HoP on the properties of DM. The present paper has the aim of reviewing the published papers on this topic, and to provide a comparison of the reported variations of biologically-active DM components before and after HoP. This review was performed by searching the MEDLINE, EMBASE, CINHAL and Cochrane Library databases. Studies that clearly identified the HoP parameters and compared the same DM samples, before and after pasteurization, were focused on. A total of 44 articles satisfied the above criteria, and were therefore selected. The findings from the literature report variable results. A possible explanation for this may be the heterogeneity of the test protocols that were applied. Moreover, the present review spans more than five decades, and modern pasteurizers may be able to modify the degradation kinetics for heat-sensitive substances, compared to older ones. Overall, the data indicate that HoP affects several milk components, although it is difficult to quantify the degradation degree. However, clinical practices demonstrate that many beneficial properties of DM still persist after HoP.

Benefits of donor milk in the feeding of preterm infants.

Mothers own milk is widely recognized as the optimal feeding for term infants, but also provides health benefits that are of vital importance for sick and preterm infants in neonatal intensive care units (NICUs), even though the growth and neurodevelopmental needs of very premature infants are best met by appropriate fortification of human milk (HM). When mothers milk is unavailable or in short supply, donor milk (DM) represents the second best alternative and, although some nutritional elements are inactivated by the pasteurization process, it still has documented advantages compared to formula. Occasionally, the concern that the use of DM might decrease breastfeeding is being raised, but reports exist in literature showing that the use of donor HM in the NICU increases breastfeeding rates at discharge for VLBW infants. The demonstrated benefits of HM highlight the importance of educating health care professionals in breastfeeding support.

Methemoglobinemia caused by the ingestion of courgette soup given in order to resolve constipation in two formula-fed infants

Methemoglobinemia is not a rare condition arising from the exposure to hemoglobin-oxidizing agents such as nitrates-nitrites present in well water or vegetables. Infants <3 months of age are more susceptible than adults because of lower amounts of a key enzyme, NADH-cytochrome b5 reductase, which converts methemoglobin back to hemoglobin. We report 2 infants, aged respectively 2 and 1 months, suffering from methemoglobinemia, fed with a formula that was reconstituted with a high concentration of courgette soup to resolve constipation. They developed a severe cyanosis with methemoglobinemia (respectively 30.4 and 27%) and were hospitalized and treated with methylene blue at 1%. After 12 h the syndrome was completely resolved. Home-prepared infant foods containing vegetables are potential causes of methemoglobinemia. It is important not to feed infants with vegetables having a high nitrate content (e.g., courgette, spinach, beets and green beans) to resolve constipation since, particularly in the first months of life, they may cause severe methemoglobinemia.

Perfusion index variations in clinically and hemodynamically stable preterm newborns in the first week of life

BackgroundThe perfusion index, derived from the pulse oximeter signal, seems to be an accurate predictor for high illness severity in newborns. The aim of this study was to determine the perfusion index values of clinically and hemodynamically stable preterm newborns in the first week of life.MethodsPerfusion index recordings were performed on the first, third and seventh day of life on 30 preterm newborns. Their state of health was assessed according to clinical and behaviour evaluation and to the Score for Neonatal Acute Physiology.ResultsThe median(interquartile range) perfusion index values were 0.9(0.6) on the first, 1.2(1.0) on the third, and 1.3(0.9) on the seventh day, with a significant increase between the first and the third day.ConclusionsPerfusion index proved to be an easily applicable, non-invasive method for monitoring early postnatal changes in peripheral perfusion. Its trend during the first week of life suggests that its clinical application should take age into account. Further studies are needed to obtain reference perfusion index values from a larger sample of preterm newborns, to identify specific gestational age-related cut-off values for illness and to test the role of perfusion index in monitoring critically ill neonates.

Advances in the management of digestive problems during the first months of life

UNLABELLED A study was carried out on 168 full-term infants with digestive problems such as regurgitation and/or constipation to evaluate the efficacy of new infant formulas containing partially hydrolysed whey protein, modified vegetable oil with a high beta-palmitic acid content, prebiotic oligosaccharides and starch. Infants receiving the new formulas had an increase in stool frequency of 0.60 between day 1 and day 7 (95% CI 0.19-1.01; p=0.004) and 0.53 (95% CI 0.11-0.90; p=0.015) between day 7 and day 14. A reduction of 1.06 in the number of regurgitation episodes was reported between day 1 and day 7 (95% CI 0.24-1.88; p=0.012) and 1.31 (95% CI 0.42-2.21; p=0.005) between day 7 and day 14. CONCLUSION A prebiotic mixture of galacto-/fructo-oligosaccharides with a high beta-palmitic acid content may reduce digestive problems and improve intestinal tolerance in infants during the first months of life.
