RESUMEN
OBJECTIVES: Amino acid-based formulas (AAFs) are recommended for children with cow's-milk allergy (CMA) failing to respond to extensively hydrolysed formulas (eHFs). We evaluated the effects of a new thickened AAF (TAAF, Novalac), containing a pectin-based thickener, and a reference AAF (RAAF, Neocate) on allergy symptoms and safety, through blood biochemistry analysis and growth. METHODS: Infants (ages < 18 months) with CMA symptoms failing to respond to eHFs were randomised in a double-blind manner to receive TAAF or RAAF for 3 months. All of the infants were then fed TAAF for 3 additional months. Paediatric visits occurred at 1, 3, and 6 months. Blood samples were collected at inclusion and 3 months. RESULTS: Results at 1 month were previously described. The 75 infants with proven CMA and eHF intolerance tolerated their allocated formula. At 3 months, the dominant allergic symptom had disappeared in 76.2% of the infants with TAAF and in 51.5% of the infants with RAAF (Pâ=â0.026). The Scoring Atopic Dermatitis Index significantly improved more with TAAF than with RAAF (-27.3â±â2.3 vs -20.8â±â2.2, Pâ=â0.048). Of the infants, 92.9% had normal stools (soft or formed consistency) with TAAF vs 75.8% with RAAF (Pâ=â0.051). More infants in TAAF group had better quality of nighttime sleep (Pâ=â0.036) and low frequency of irritability signs (Pâ<â0.001). With both formulas, all of the biochemical parameters were within normal ranges. There were no differences between the 2 groups in any of the anthropometric z scores. CONCLUSIONS: The new TAAF was tolerated by all of the infants with CMA and intolerance to eHFs. Anthropometric and clinical data showed that both formulas were safe.

We report here a 4-month-old girl with atopic dermatitis accompanied by weight loss, electrolyte disturbance, hypoproteinemia and hypogammaglobulinemia. She has suffered from eczema since one-month of age. Although she was treated with Chinese herbal medicines, including Syosaikotokakikyosekko, Tokishigyakukagoshuyushokyoto and Jumihaidokuto and ibuprofen ointment since three-month of age, she was referred to our hospital due to deteriorated eczema, severe diarrhea and failure to thrive. Laboratory examination revealed hyponatremia, hyperpotassemia, hypoproteinemia, hypogammaglobulinemia and elevated levels of serum IL-18, TARC and fecal EDN. Drug-induced lymphocyte stimulation tests were positive for the prescribed Chinese herbal medicines. Discontinuation of these medicines and application of steroid ointments improved loose bowels and skin lesions as well as laboratory data. It is suggested that the application of inadequate ointment and Chinese herbal medicines exaggerated inflammation in the skin and the intestinal mucosa leading to electrolyte disturbance, hypoproteinemia and hypogammaglobulinemia. Chinese herbal medicines are depicted as an additional therapy in Japanese guideline for atopic dermatitis, whereas their indication to infants with atopic dermatitis should be carefully assessed.
