Take you to interpret those things about "milk protein allergy"

Speaking of cow's milk protein allergy (CMPA), many babies may suffer from it. Allergic diseases affect approximately 25% of the global population, and milk protein allergy is the most common food allergy in infants and young children. According to survey statistics, 5%-15% of infants and young children will have abnormal reactions and clinical manifestations when ingesting dairy products [1]. Today's article will talk about a few issues that mothers are usually concerned about about milk protein allergies.
  • What are the symptoms of a baby's milk protein allergy?
  • What should I do if I suspect a milk protein allergy?
  • Babies with milk protein allergy should pay attention to adding complementary foods?
  • Does milk protein allergy get better with age?
01What are the symptoms of a baby's milk protein allergy? Let's look at two cases first: Case 1, 2-month-old Dudu was hospitalized for 1 week due to jaundice when he was born; at that time, he was fed formula milk, and he mainly ate breast milk after being discharged from the hospital; in the past month, he was intermittently supplemented with formula milk, and several occurrences occurred during this period. Blood in the stool, feeding less than before. In the hospital, there were a few white blood cells and red blood cells in the stool routinely. The doctor diagnosed it as "enteritis". The oral cephalosporin did not improve, and there were still blood threads in the discharged stool. The physical examination revealed a good response, no abnormality in the abdomen, and no anal fissure. After asking about the family history, the father was allergic to milk, eggs, and shrimp. The doctor finally made a diagnosis: milk protein allergy. After avoiding milk food for 1 month, there was no bloody stool again, and the weight gradually increased and the appetite improved. Case 2 An An, who was born 6 months ago, began to have eczema, spit up milk easily, breastfeeding, and slow weight gain 2 months ago, and these symptoms became more and more serious. The sleep is not stable, it takes a long time to be comforted to fall asleep, and then suddenly wake up screaming and crying, which is difficult to be comforted. After inquiring about the feeding situation in detail, it was found that An An started adding milk powder 2 months ago, and no abnormal findings were found in the physical examination. Diagnosis: Milk protein allergy. After switching to deeply hydrolyzed protein milk powder feeding, An'an's sleep condition was significantly improved, and she gradually returned to normal weight gain. (The above two cases are from Zhuozheng Medical) Through the above two cases, it is reflected that the child is allergic to milk protein, and the symptoms may be manifested in the gastrointestinal tract, skin, etc., and may also have growth and development disorders. That's when mom needs to be vigilant. Milk protein allergy is divided into mild-moderate and severe according to clinical manifestations. Let's look at the symptoms of different grades: Most exclusively breastfed children have mild-moderate milk protein allergy. Children with severe milk protein allergy will have acute clinical manifestations (such as laryngeal edema, anaphylactic shock, etc.) and affected growth and development (such as dysplasia, growth retardation), and these manifestations also distinguish between severe and mild-moderate milk. The main basis for protein allergy [1]. 02What should I do if I suspect a baby's milk protein allergy? First of all, you should take your baby to the doctor for a check-up to determine whether the baby is allergic to cow's milk protein. If a milk protein allergy is determined, there are different treatment methods for babies with different feeding methods: breastfeeding mothers strictly avoid milk and its products (such as: milk, yogurt, cheese, cake, milk-containing biscuits, etc.) for at least 2 weeks, If the baby's symptoms improve significantly while the mother is avoiding the diet, the mother can try adding milk gradually. If symptoms do not recur, normal diet can be resumed; if symptoms recur, mothers should avoid a diet containing milk and its products during breastfeeding, continue breastfeeding for at least 6 months, and after weaning from breast milk Give heavily hydrolyzed protein formula or amino acid formula instead [2]. Milk is the main source of calcium, and mothers should pay attention to calcium supplements when avoiding diet. The recommended daily calcium intake (RNI) for lactating women is 1000 mg/day. Infants and young children with severe cow's milk protein allergy can directly consider using deeply hydrolyzed protein formula or amino acid formula milk instead when the mother's dietary avoidance is ineffective. Formula feeding ≤ 2 years old: Foods and formulas containing cow's milk protein should be completely avoided and replaced with hypoallergenic formula (such as amino acid formula or deeply hydrolyzed formula), and the infant can be fed continuously until 6 months or until 9-12 age in months [2]. > 2 years old: The child's food source is relatively rich, which can meet the needs of growth and development, so a dairy-free diet can be adopted. How to choose milk powder with different degrees of hydrolysis? Amino acid formula milk is made of complete free amino acids in a certain proportion, and does not have immunogens that can cause human immune responses; it is recommended to use amino acids for infants with severe milk protein allergies whose growth and development are affected, and who cannot tolerate deeply hydrolyzed formulas. formula. Deeply hydrolyzed formula milk is the final product of forming milk protein into short molecular chain dipeptide, tripeptide and a small amount of free amino acid through a special process, which reduces the spatial structure of allergens and is suitable for most infants and young children allergic to milk protein. , Infants with <10% cow's milk protein allergy cannot tolerate deeply hydrolyzed formula. Therefore, babies with allergic symptoms should first try to deeply hydrolyze formula powder when changing milk powder, pay attention to whether the child has allergic reactions, and if so, change to amino acid milk powder [2]. Infants and young children who eat amino acid formula or deeply hydrolyzed formula powder usually need to continue for 3-6 months before trying partially hydrolyzed milk powder, and at the same time, they need to seek medical attention to evaluate whether they need to make dietary adjustments. Some mothers may have such doubts: Can they be allergic to cow's milk protein and can be replaced with goat milk powder and soy milk powder? The answer is not recommended; the proteins in goat milk powder and milk powder are macromolecular proteins, and eating goat milk powder may cause cross-allergies. Soy protein formula milk, made from soybeans, does not contain milk protein, and other basic ingredients are the same as conventional formulas. However, due to the cross-allergic reaction between soy and milk and its nutrition cannot meet the needs of infants, soy protein formula milk is generally not recommended. For infants >6 months who have real financial difficulties and no soy protein allergy, soy protein formula can be used, but it is not recommended for those with colic symptoms [2]. Q: Some mothers think that hydrolyzed milk powder is not nutritious, is that true? A Hydrolyzed milk powder is a medical special infant formula milk powder that meets the national standards for special infant formula milk powder and has passed the formula registration. Under the premise of ensuring the milk supply of the child, nutrition can fully meet the normal growth and development needs of infants and young children. Some babies don't like the taste of hydrolyzed milk powder very much, but for the growth and development of the baby, it is still necessary to let the baby try more contact, bottle feeding, spoon feeding and other methods gradually allow the baby to gradually adapt to it. 03What should I pay attention to when adding complementary food to babies with milk protein allergy? There are currently no guidelines recommending that the introduction of complementary foods should be delayed for children with cow's milk protein allergies. Generally speaking, on the premise that the child's allergy symptoms are under control, after the child reaches the age of 6 months, the complementary food should be added according to the principle of addition. The principles of adding complementary foods are as follows:
  • Add only one new food at a time, from less to more, from thin to thick, and from thin to thick, step by step;
  • Adapt to a food for 2-3 days every time you introduce it, and closely observe whether there are adverse reactions such as vomiting, diarrhea, and rash;
  • Adapt to a food After that, add other new foods [3].
The first food added should be free of allergens. You can start with iron-rich pure rice noodles, and gradually introduce various vegetables, fruits, etc., and gradually transition to livestock, poultry, eggs, fish and shrimp and other foods. If it is necessary to switch from amino acid milk powder (AAF) to highly hydrolyzed formula milk powder (eHF) at the same time, the addition of complementary food should be suspended during the weaning period, so as to better observe the situation of the baby during the weaning process. 04 Will babies with cow's milk protein allergy get better with age? The answer is not sure. As the child grows older, the baby's intestinal barrier gradually develops and matures, and the immune function becomes more and more perfect. There are also a small number of children with cow's milk protein allergies that persist into adolescence or beyond. In short, mothers should not be too anxious for babies with milk protein allergies. They can relieve the baby's current situation by correcting the way of avoiding food or changing the feeding method. When buying snacks for babies over 6 months old, you should first read the food labels to see if they contain "milk protein" allergens to avoid unintentional ingestion.
