Antibodies of various immunoglobulin classes against cow's milk proteins were studied in infants and children with cow's milk protein intolerance, gluten-sensitive enteropathy and acute gastroenteritis. Their IgE, IgG, IgM and IgA antibody levels determined with the enzyme-linked immunosorbent assay (ELISA) and the IgE antibodies also determined with RAST, were compared with reference groups of children and adults. IgE, IgT or IgA antibodies against unseparated cow's milk proteins, alpha-lactalbumin, beta-lactoglobulin, alpha-casein and beta-casein were present in many of the studied samples, but did not discriminate between the individuals with and without intolerance symptoms. As a group, the infants with late reactions to cow's milk showed increased levels of IgE and IgG antibodies detected with the ELISA, while patients with gluten-sensitive enteropathy had significantly increased levels of IgG and IgA antibodies of cow's milk proteins compared to the reference group. By combining the findings of antibody increases in various immunoglobulin classes, an individual discrimination could be reached. Thus, 8 of 9 of the patients with late reactions to cow's milk had increased levels of IgE or IgG + IgA antibodies as compared to 3 of 22 in the reference group. Serodiagnosis with the ELISA may, therefore, be of some use in patients with a suspicion of cow's milk protein intolerance.

The diagnosis of Cow's Milk Protein Allergy was considered in 303 infants aged less than 1 year, who presented with one or more of the following symptoms: acute reaction related to cow's milk proteins (CMP) ingestion, severe colics, persisting vomiting, protracted diarrhea with or without blood and mucus, failure to thrive, eczema, respiratory symptoms, such as chronic rhinitis and wheezing. A diagnosis of CMPA was confirmed in 148 cases (60%): 125 relapsed on milk challenge, 23 were not challenged because of acute reactions at onset, presence of specific IgE (RAST and prick), and improvement on milk free diet. Familial atopy, familial history of CMPA and previous acute gastroenteritis were significantly more frequent in cases than in 191 age matched controls. Breast feeding was not more common or of longer duration in controls, compared to cases. Mean IgE serum levels were higher (46.3 U/ml) in cases than in controls (17 U/ml), while specific Cow's Milk Protein IgE were found in 71/148 cases (48%). 15 infants entered the study while on breast milk, because of the confirmed relation between their symptoms and CMP on the maternal diet. These infants had a higher prevalence of IgE mediated problems. All cases improved on a milk free diet but in 26 (17.8%) a further modification of the diet was required after the first prescription. Milk challenge was monitored by simple laboratory tests: all cases who had symptoms on challenge showed at least one test modification. Six infants, with no history of acute reaction, showed severe self-limited clinical symptoms at challenge. Key words: cow's milk allergy, milk, allergy, prick test, eczema, diarrhea.

We have reviewed 53 cases of allergic disorders of the gastrointestinal tract in children, including 15 with principal effects in the rectum (allergic proctitis) and 38 with dominant involvement of the upper and mid portions of the gut (allergic gastroenteritis). Most cases of allergic proctitis had their onset at less than 6 months of age, and all were under 2 years old when they presented with rectal bleeding alone or in combination with diarrhea. Rectal mucosal biopsy revealed in most cases a diffuse increase of eosinophils in the lamina propria together with a focal infiltration of the epithelium by eosinophils. Cases of allergic gastroenteritis affected all age groups and had a lower frequency of overt rectal bleeding. More common were other symptoms (vomiting, pain, and weight loss), an allergic history, anemia, blood eosinophilia, and increased serum IgE. Mucosal biopsy abnormalities were present in the gastric antrum in all cases sampled, the small intestine in 79%, the esophagus in 60%, and the gastric corpus in 52%. The lesions were usually diffuse and marked in the antrum and esophagus; in contrast, they tended to be focal and mild in the small intestine and gastric corpus. All cases of proctitis responded to a dietary change by cessation of symptoms without recurrences, whereas most of those with gastroenteritis had multiple relapses and required corticosteroid therapy.

Sixty-five infants (mean age 14.7 months, range 6-34 months), hospitalized for acute gastroenteritis, were treated with oral rehydration and rapid reintroduction of full feedings appropriate for age. Cow's milk and milk products were eliminated from the diet of 27 infants, whereas the remaining 38 children continued to receive their usual milk and milk products as parts of the mixed diet. There was no difference between the groups in the clinical recovery from diarrhea. No child had prolonged diarrhea. No new cases of clinical atopy were observed at 1-month follow-up, and there were no significant increases in the total or milk-specific IgE levels. Serum IgG and IgA antibodies to beta-lactoglobulin and alpha-casein were initially present in the majority of the children, but there were no appreciable changes in these cow's milk antibodies after gastroenteritis, regardless of the type of diet. It is concluded that cow's milk and milk products can be safely given in acute gastroenteritis as parts of the mixed diet for children over 6 months of age. Rapid reintroduction of feedings is beneficial for recovery from diarrhea, and there appears to be little need for dietary restrictions in this age group.

Jejunal biopsies from 20 well nourished children (average age 12.8 months) with gastroenteritis, and 20 children (average age 20 months) with protein-energy malnutrition were examined by immunofluorescent technique for immunoglobulins A, G, M, E, and D, and for epithelial glycoprotein secretory component. Compared with previous studies on normal infants, the children with gastroenteritis showed a moderate increase in IgA-containing cells, a large increase in IgM-containing cells, and no change in IgG-containing cells. These findings are similar to previously recorded findings on adults with gastroenteritis. In contrast there was a pronounced and highly significant decrease in IgA-containing cells in the jejunal mucosa of the children with protein-energy malnutrition. No significant differences were noted between the populations of IgG-, IgM-, IgE-, and IgD-containing cells in the two groups. It is suggested that this selective deficiency in mucosal IgA results from a delay in maturation of the secretory IgA system, and the mechanisms of such a deficiency are discussed.

ALCAT Test results were the base for elimination diet treatment in several ailments regarded as the result of food allergy (intolerance) in 72 patients (45 children and 27 adults). The best results were achived in arthritis, urticaria, bronchitis, gastroenteritis (83%, 75%, 70% of improvement in treated patients respectively). Worse results were observed in children hypereactivity, rhinitis and atopic dermatitis (32%, 47%, 49% of improvement respectively). Less satisfactory effects of the elimination diet treatment based on the ALCAT Test results in the two latter diseases may result from the considerable involvement of IgE-mediated mechanism in the pathology of the skin and nose, which are under a great influence of external environmental factors other than food. In 57% of patients skin prick tests were positive (in 35% with inhalants and foods, 12% with inhalants only, in 9% with foods only).

A male infant was born with generalized erythroderma and scaling; the newborn demonstrated poor neonatal development and developed several complications such as hypernatremic dehydration, septicemia, gastroenteritis and seizures. In the neonatal period, the erythema faded, but exfoliation persisted. The parents are healthy but related. One older brother, who died at the age of 3 months, had shown the same clinical picture in the neonatal period and was diagnosed with congenital psoriasis. All clinical investigations, including serum immunoglobulins, complement levels and lymphocyte counts, were normal. Only raised total IgE and multiple positive specific IgE reactions were noted. Skin biopsy revealed an image of ichthyosis. Polarization microscopy of scalp hair showed trichorrhexis nodosa and discrete focal twisting of the hair shaft. This clinical picture and all histological findings are compatible with the indications of Netherton's syndrome. The purpose of this report is to call attention to this severe presentation of congenital ichthyosis in the neonatal period and to the difficulty of a correct diagnosis when confronted with congenital erythroderma.

Atopic diseases of infants and children are common, debilitating, chronic and sometimes even life-threatening. Several well-conducted studies in high risk babies have demonstrated a significant reduction in the prevalence and severity of atopic diseases with dietary and environmental manipulations. The currently available cow's milk (CM) substitutes for infants are soy protein (SP) formulas (SPFs), hydrolyzed formulas (HF), and home-made meat-based formulas. Soybeans have been cultivated in Eastern countries for many centuries and were first used to feed US babies with CM allergy (CMA) in 1929. Since then, SPFs containing purified SP, a mixture of vegetable oils, and purified carbohydrate have been developed. From a nutritional point of view, SPFs are adequate, support normal growth, protein status, bone mineralization, are well accepted, and economical. SPFs are used for different conditions including CMA, lactose and galactose intolerance and in the management of severe gastroenteritis, and some studies show that feeding SPFs for the first six months of life significantly reduces the prevalence of atopic diseases in high risk babies. Although gastrointestinal symptoms and atopic dermatitis (AD) may occur in some SPF-fed children, anaphylaxis following the ingestion of soybean is extremely rare in children. However, in the past few years the antigenicity/allergenicity of SPFs has been over-emphasized in the medical literature. In this paper on the natural history of soy antigenicity/allergenicity we discuss all the pros and cons of SPFs, their composition and nutritional value, the basic immune definitions, chemistry and characterization of SPs. We then discuss the antigenicity and allergenicity of SPFs in animals, recent data on the use of SPFs and the incidence of soy allergy in children, clinical reactions to SPFs, and the clinical relevance of skin testing and IgE antibodies to soy, challenge test procedure, clinical indication of SPFs, and their relevance in the prevention of atopy. We have meta-analyzed 17 different studies and conclude that history-based SPF allergy incidence totals 27%, in skin prick tests (SPT) RAST-oral food challenge (OFC)/double-blind food challenge (DBFC)-based epidemiological studies attains 3%, and in challenge test studies 4%. We suggest that double-blind placebo-controlled food challenge (DBPCFC) studies in larger cohorts of babies may establish a more reliable prevalence of SPF allergy in different disorders associated with CMA.

The mechanisms responsible for sensitization, in particular within the gastrointestinal tract, are IgE-mediated as well as of a non-IgE-mediated, immunological origin. The phenomenon that is the opposite of sensitization is the maintenance of tolerance and is exemplified by the phenomenon 'oral tolerance'. The cytokines transforming growth factor beta and interferon gamma have been shown to be key immunoregulatory cytokines in oral tolerance. A new experimental model of eosinophilic allergic gastroenteritis has been developed with the use of encapsulated dietary antigen. The model was used in mice with genetic deletions of the eosinophil chemokine eotaxin or of the cytokine IL-5, demonstrating the importance of eotaxin. In clinical allergy research, a major question has been to explain the global increase in asthma and allergy. The 'hygiene hypothesis' states that a lack of maturation of the infant immune system from a T helper 2 to a T helper 1 type of immune response may be caused by less microbial stimulation in Western societies. Several lines of data support this hypothesis. However, apart from the genetic constitution of the individual, breastfeeding in infancy may be the most important single determinant for the development of clinical tolerance.
