Hypoallergenic amino acid-based Medical Food.
Last Updated: Wednesday, December 23, 2015
PurAmino™ Toddler is an iron-fortified, hypoallergenic, amino acid-based toddler medical food for the dietary management of toddlers with severe cow's milk protein allergy, not effectively managed by an extensively hydrolyzed formula. PurAmino Toddler is also indicated for the dietary management of toddlers with multiple food protein allergies. It may also be suitable for conditions requiring an elemental diet such as protein maldigestion, malabsorption, short bowel syndrome, and eosinophilic esophagitis.
PurAmino Toddler is designed to provide a major source of nutrition for toddlers age 1 year and up. In cases of severe and multiple food allergies or intolerances, PurAmino Toddler is sometimes continued as a milk substitute in the diet of children. This and similar supplemental use of PurAmino Toddler in the diet may make a significant contribution to maintenance of good nutrition in such patients.
When PurAmino Toddler is used as a milk substitute, the total calcium content of the diet should be assessed.
Extended use of PurAmino Toddler (or other toddler formulas) is most appropriately monitored by physicians and nutritionists on a case-by-case basis, with attention to developmental as well as nutritional implications of such a dietary regimen.

Cow's milk protein allergy occurs in approximately 2%–3% of infants14. Many healthcare professionals use an extensively hydrolyzed protein formula for the dietary management of cow's milk protein allergy. However, up to 10% of infants with severe cow's milk or food protein allergies develop specific IgE against extensively hydrolyzed casein or whey protein and may require a special formula made of free amino acids. Several of the studies using amino acid–based formulas are summarized below.
Elimination of milk and other foods from a child's diet as part of the management of milk protein allergy and/or multiple food protein allergies may impact growth and overall nutritional status15. Therefore, it is not surprising that the key criteria for assessing the safety and efficacy of a hypoallergenic formula are weight gain and height increases. In this regard, there are a number of clinical studies demonstrating that amino acid–based formulas can both improve compromised growth in infants and young children with severe cow's milk protein allergy and/or multiple food protein allergies and continue to support their growth when used for a short period or long term15-20.
Safety and Efficacy
There are several clinical trials demonstrating the safety and efficacy of reduced antigenic dietary products. However, adverse responses to these cow's milk substitutes may continue to persist in some highly allergic infants. Incidence allergic responses to hydrolyzed formulas, including extensively hydrolyzed formulas, has been reported over the past few years21,22.
In contrast to the residual allergenicity of partial and extensively hydrolyzed formulas, formulas based on free amino acid solutions are designed to contain no intact proteins or peptides23,24. As a result, there is substantial clinical evidence demonstrating the efficacy of amino acid–based formulas in these situations.
Skin Health and Digestive Health
In the dietary management of cow's milk protein allergy, benefits in skin health as well as digestive health are often seen. Atopic dermatitis is common in infants with cow's milk allergy. It has been reported that about one third of infants with severe atopic dermatitis have clinical reactivity to food proteins, including cow's milk and soy proteins25. There have been several clinical studies evaluating the efficacy of amino acid-based formulas in improving skin health as a result of continued allergenicity to cow's milk formula and extensively hydrolyzed proteins15,18,23,26. The SCORAD (SCORing Atopic Dermatitis) has been shown to decrease as dietary management with an amino acid-based formula is continued18.
Digestive issues are common in infants with an allergy to cow's milk protein or extensively hydrolyzed protein formulas. Multiple food protein allergies have been implicated as one of the causes of persistent child distress. It is well known that dietary antigens are capable of provoking gastroduodenal inflammations and hypermotility in hypersensitivity reactions. A number of clinical studies demonstrate the efficacy of amino acid-based formulas for improved GI health in infants and children allergic to cow's milk protein and extensively hydrolyzed protein formulas17,19,23,26-29.
Multiple Food Allergies
Studies suggest that many children who are allergic to cow's milk protein may develop an allergy to a large variety of other foods, such as eggs, wheat, peanuts, soy and even protein hydrolysates. This scenario is typically defined as “multiple intolerances” to dietary proteins in children and may affect 5%–8% of children during the first three years of life17,20,26,29. According to Latcham et al30, "recently there have been increasing reports of multiply-sensitized infants, often despite exclusive breastfeeding.” In the initial studies of Hill et al19, some patients with cow's milk allergy also had adverse reactions to soy milk or casein hydrolysates. Many were also intolerant to other foods (ie, multiple food proteins). A delay in the diagnosis and initiation of appropriate dietary management could sustain and/or worsen these multiple allergies. Clinical studies by Ammar et al17, Hill et al19 and Latcham et al30 add to the growing body of evidence demonstrating the potential benefits of using an amino acid-based formula for the dietary management of infants with multiple food allergies. PurAmino Toddler is a hypoallergenic formula for patients with severe cow's milk allergy and multiple food allergies.
Malabsorption and Maldigestion
Conditions resulting in maldigestion and malabsorption can be problematic for maintaining or achieving appropriate nutrient status and potentially have additional effects such as gastrointestinal issues, changes in stool patterns, and ultimately impact growth and development. Clinicians may often recommend use of an elemental formula to help promote absorption of essential nutrients. Indeed, studies in infants and children with chronic diarrhea suggest that use of an elemental formula may be beneficial. Antonson and colleagues examined the effects of an amino acid-based formula with MCT oil on 27 infants <12 months of age with chronic diarrhea, with improvements in growth and gastrointestinal issues reported31,32.
Short Bowel Syndrome
Elemental diets may also be considered for patients with short bowel syndrome. While some cases are congenital, short bowel syndrome is typically a result of intestinal resection, in which parts of the small and/or large intestine are removed due to disease or trauma33. Bowel resection reduces the absorptive surface area of the gut, which can lead to maldigestion and malabsorption. Thus, strategies for improving nutrient digestion and absorption are necessary to promote growth and development. Protein hydrolysate or amino acid-based formulas are often used in the dietary management of infants and children with short bowel syndrome33-35. In terms of the lipid requirements, it has been suggested that a mixture of both medium-chain and long-chain triglycerides is needed in patients with short bowel syndrome34,36. Due to the malabsorption that occurs, MCTs are particularly important as they are easily and quickly absorbed; however, long-chain triglycerides are still needed as they are key for stimulating trophic effects in the intestine as well as meeting essential fatty acid requirements33,36.
Indeed, studies suggest amino acid-based formulas may be beneficial. Using a retrospective chart review of children with short bowel syndrome, Andorsky and colleagues noted that use of an amino-acid based formula was associated with a shorter duration of parenteral nutrition use45. Similarly, Bines and colleagues conducted a small study of infants and children with short bowel syndrome who had a feeding intolerance to hydrolyzed formulas, noting that feeding tolerance improved within 1 month and patients were weaned from parenteral nutrition within 15 months27.
In addition to the conditions described above, elemental formulas are also commonly used in patients with eosinophilic esophagitis. Dietary recommendations include food eliminations based on allergy testing or use of an amino acid-based elemental formula in infants and children38. Indeed, studies conducted by Liacouras et al39, Markowitz et al40, and Kelly et al41 suggest that elemental formulas improve gastrointestinal issues and esophageal histology in infants and children.
