水解蛋白配方与婴幼儿牛奶过敏的预防和治疗 总被引:2,自引:0,他引:2
食物过敏是婴幼儿最早出现的过敏问题,牛奶是婴幼儿最常见的过敏食物。牛奶过敏的临床表现多种多样,可涉及皮肤、呼吸道、消化道等多器官多系统。母乳喂养是过敏高风险婴儿的首选喂养方式,但对不能进行母乳喂养的婴儿应选择适当的低敏配方奶,水解蛋白是获得低敏配方的最好方法。根据水解的程度,水解蛋白配方分为适度水解蛋白配方和完全水解蛋白配方。完全水解配方被推荐用于牛乳蛋白过敏婴儿的治疗,适度水解配方通常推荐用于特应质高风险婴儿的初级干预。 相似文献

<正>婴儿期最常见的过敏性疾病是食物过敏,由于牛奶蛋白是婴儿期主要的食物蛋白来源,所以婴儿期食物过敏以牛奶蛋白过敏(cow's milk allergy,CMA)最为常见。牛奶蛋白过敏可涉及全身各个系统,并以消化系统症状和皮肤症状为最主要表现。如:呕吐、反流、腹泻、便血、肠绞痛、湿疹、荨麻疹等。这些症状均为非特异性。单从临床症状判断是否为食物过敏有一定的困难,需要结合辅助检查进行综合分析。本文探讨婴儿牛奶蛋白过敏的诊断及鉴别诊断。 相似文献

Cow's milk protein allergy (CMPA) is best treated by complete elimination of cow's milk from the diet. For infants with CMPA who cannot be breast-fed, formulas based on extensively hydrolyzed proteins or on amino acids are the preferred substitutes for cow's milk-based formulas. In this study, we compared the tolerance and growth of infants with CMPA who were fed a new extensively hydrolyzed formula containing lactose (eHF) with those who were fed an amino acid formula (AAF). This was a prospective, multi-center, randomized, reference-controlled study. Seventy-seven infants <12 months old with suspected CMPA were enrolled. In 66 of these, CMPA was confirmed by oral challenge in a double-blind, placebo-controlled food challenge (DBPCFC) or by a medical history of severe allergic reaction to cow's milk and a positive skin prick test. These infants were then tested for their reaction to eHF and AAF in a DBPCFC. All infants tolerated both formulas and were randomized to receive either eHF (n = 34) or AAF (n = 32) for 180 days. Growth (weight, length, and head circumference) and tolerance [skin, gastro-intestinal, and respiratory tract symptoms of allergy] were evaluated after 30, 60, 90, and 180 days. There were no significant differences between the two groups in any of the growth measurements. Length and head circumference were similar to Euro-growth standards, but weight was slightly lower. Gastro-intestinal and respiratory tract symptoms of allergy were also similar in the two groups. However, whereas SCORAD scores for atopic dermatitis remained constant throughout the study in infants-fed eHF, there was a slight decrease in those fed AAF. Infants-fed eHF had significantly fewer incidents of vomiting than infants-fed AAF and a significantly higher frequency of soft stools. The new eHF is safe and well tolerated in infants diagnosed with CMPA. 相似文献

Abstract. 1079 of 1548 newborn infants were followed during their first year. 328 were prospectively contacted once a month. 751 were followed up at child welfare clinics. Altogether 20 were diagnosed as being cow's milk protein intolerant (1.9%). Symptoms from the gastrointestinal tract and the skin predominated. Only 2 had respiratory symptoms. Ten had their symtpoms within one week after the introduction of cow's milk, 3 of them at their first cow's milk-containing meal. A further 4 already had symptoms when fed only human milk. The others (6 infants) showed symptoms after more than one week on a cow's milk containing diet. Before 2 years of age, 13 had recovered. Twelve of the cow's milk protein intolerant infants also showed adverse reactions to other foods, soy-protein intolerance being the most common (7 infants). A family history of allergy was found in 35% (116) of the 328 infants and in 70% (14) of those with cow's milk protein intolerance. 相似文献

Childhood cow's milk allergy is a diagnosis encompassing various syndromes. Antigen-immunoglobulin E (IgE) antibody interaction is classically involved in mast cell degranulation in IgE-mediated food allergy, while non-IgE mediated cow's milk allergy is mostly mediated by cellular mechanisms. The diagnosis of cow's milk allergy largely relies on a good knowledge of the clinical expression of the disease. In this educational review series, we describe three cases of cow's milk allergy, first a 7-yr-old girl with persisting IgE-mediated cow's milk allergy, second a 8-month-old boy with cow's milk induced flares of atopic dermatitis, and third a 6-yr-old boy with sheep and goat milk allergy, in the absence of cow's milk allergy. The cases are discussed and summarized with more general recommendations for the clinical management of cow's milk allergy. 相似文献

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

Cow's milk protein (CMP) allergy was investigated in 25 children (age-range 3 months to 11 years) with chronic constipation. A diagnosis of constipation was made on the basis of a history of painful elimination of hard stools for at least 1 month, whether or not associated with a reduced frequency of stools or soiling. The children were evaluated using clinical parameters and the following laboratory tests: total serum immunoglobulin E (IgE); specific IgE (radioallergosorbent test [RAST]) for whole cow's milk, α-lactoalbumin, β-lactoglobulin, and a food group; and skin-prick tests with whole milk, α-lactoalbumin, β-lactoglobulin, and casein. Following the evaluation, the children were submitted to a CMP-free diet for a period of 4 weeks. In seven patients (28%), constipation disappeared during the CMP-free diet and reappeared within 48–72 h following challenge with cow's milk. In two infants a rectal biopsy revealed allergic colitis and they therefore did not undergo the challenge. High serum levels of total IgE were observed in five of the children who showed a clinical improvement (71%), a positive skin-test in two (29%), and detectable specific IgE in two (29%). These results suggest that CMP allergy or intolerance should be considered as a cause of chronic refractory constipation in children, although the underlying mechanism still require further investigation. 相似文献

ABSTRACT. During a nutritional study of 198 infants, seven became allergic to cow's milk. The seven infants showed acute cutaneous manifestations during cow's milk challenge tests in hospital and six had increased levels of IgE cow's milk-specific antibodies. Neither in the development of the levels of immunoglobulins G, A and M, nor in that of the cow's milk-specific antibodies of these isotypes did these seven patients differ from the remaining infants. Beta-lactoglobulin content and levels of cow's milk-, and beta-lactoglobulin-specific antibodies and of immunoglobulins A, G and M were measured in samples of colostrum and milk from the mothers of the seven infants with cow's milk allergy and from a comparison group (non-atopic mothers of non-atopic infants). The milk of the mothers whose infants became allergic to cow's milk contained less IgA through the lactation: 95% confidence intervals of the groups did not overlap. The difference was most marked in the colostrum. All other measurements were similar in the two groups. This suggests that an infant is more likely to develop cow's milk allergy if the mother's colostrum had a low total IgA content. 相似文献

Cases of cow's milk protein allergy have been occasionally reported after neonatal intestinal surgery. AIM OF THE STUDY: To measure the prevalence of cow's milk protein allergy (CMPA) following neonatal intestinal surgery. PATIENTS AND METHODS: The files of all children who underwent intestinal surgery in the neonatal period over a four-year-period were reviewed. The diagnosis of CMPA was made on the association of one or several symptoms suggesting food allergy after the introduction of cow's milk protein in the diet, the disappearance of the symptoms after exclusion of cow's milk protein from the diet and their reappearance after reintroduction of cow's milk protein. RESULTS: During the study period, 251 neonates underwent an intestinal surgery. Among them, 11 babies (4.3%) developed CMPA. None of them had a medical history of family atopy. Moreover, while 5 children were fed with a diet containing cow's milk protein before surgery: none of them presented initially with symptoms suggesting CMPA before intestinal surgery. Small intestine suffering was observed during operation in seven of 11 patients. No specific neonatal digestive disease or malformation was associated with CMPA. The signs revealing CMPA were primarily digestive : diarrhoea (N =3), vomiting (N =4), abdominal distension (N =2), colic or anorexia (N =2). Casein specific immunoglobulin E were present in nine of ten cases, alpha lactalbumin and/or beta lactoglobulin specific immunoglobulin E were present in six of ten cases. Prick test were performed in three children and were positive. CONCLUSION: The high prevalence of CMPA among these patients with no risk factors of allergy raises the question of the role of neonatal intestinal surgery in developing food allergy. These data should be confirmed by prospective case-control studies. They underline the interest to evoke the diagnosis of CMPA when digestive symptoms occur after milk protein introduction in children undergoing neonatal intestinal surgery. Breast feeding or milk protein hydrolysate formula should be used for refeeding these patients. 相似文献

Cow's milk protein allergy (CMPA) is the first allergy that affects infants. In this population, the incidence rate reaches 7.5%. The multiplicity and aspecificity of the symptoms makes its diagnosis sometimes complicated, especially in the delayed type (gastrointestinal, dermatological, and cutaneous). CMPA symptoms can develop in exclusively breastfed infants with an incidence rate of 0.5%. It, therefore, raises questions about sensitization to cow's milk proteins through breast milk. Transfer of native bovine proteins such as β-lactoglobulin into the breast milk is controversial: some authors have found bovine proteins in human milk but others point to cross-reactivity between human milk proteins and cow's milk proteins. However, it seems that a small percentage of dietary proteins can resist digestion and become potentially allergenic. Moreover, some authors suspect the transfer of some of these dietary proteins from the maternal bloodstream to breast milk, but the mechanisms governing sensitization are still being studied. Theoretically, CMPA diagnosis is based on clinical observations, prick-test or patch-test results, and cow's milk-specific IgE antibody concentration. A positive food challenge test usually confirms the diagnosis. No laboratory test is available to make a certain diagnosis, but the detection of eosinophil cationic protein (ECP) in the mother's milk, for example, seems to be advantageous since it is linked to CMA. Excluding cow's milk from the mother's diet is the only cure when she still wants to breastfeed. Usually, cow's milk proteins are reintroduced after 6 months of exclusion. Indeed, the prognosis for infants is very good: 80% acquire a tolerance before the age of 3 or 4 years. Mothers should not avoid dairy products during pregnancy and breastfeeding as preventive measures against allergy. 相似文献
