Background: Alternatives to cow’s milk and soy milk are often necessary for children with food allergies. Although hydrolyzed and elemental formulas are appropriate replacements, other milk products such as rice and almond milk are insufficient protein sources for children under 2 years of age. A chart review on three patients treated for protein malnutrition in association with multiple diagnosed food allergies that resulted in refractory eczema revealed adverse outcomes that resulted from elimination diets. The use of rice milk resulted in hypoalbuminemia and poor weight gain in all cases, and multiple secondary infections in one patient. These cases illustrate the need for careful nutritional guidance in the management of food allergy, as well as the importance of cautious use and interpretation of testing for food allergies in the absence of a clear clinical history of reaction.

Background: Cow's milk allergy is the most prevalent food hypersensitivity, affecting 2–3% of infants, but it tends to resolve with age. Cow’s milk-specific immunoglobulin E in the serum is an important measure in the diagnosis and follow-up of infants and children with cow's milk allergy.

Objectives: To examine the relation between CmsIgE[1] and the probability of resolution of milk allergy.

Methods: CMsIgE was determined in the serum of 1800 infants and children referred for the evaluation of possible milk allergy. All children with CmsIgE of 1 kU/L or above were followed at the allergy clinic and, according to their condition, underwent milk challenge. The diagnosis of cow's milk allergy was made on the basis of a significant and specific history or a positive oral food challenge. Subsequently, oral tolerance was defined as an uneventful oral challenge.

Results: A total of 135 infants and children had milk-specific IgE greater than 1 kU/L. Forty-one percent of children still had clinical milk allergy after the age of 3 years. Sixty-eight percent of children older than 3 years with persistence of cow's milk allergy had milk-specific IgE > 3 IU/ml before the age of 1 year. Furthermore, 70% of children who at 3 years old had resolved their cow's milk allergy had milk-specific IgE that was lower than 3 IU/ml before the age of 1 year. The positive predictive value of CmsIgE > 3 IU/ml to persistent cow's milk allergy at age 3 years was 82.6% (P = 0.001), with a sensitivity of 67.9% and specificity of 70.4%.

Conclusions: Milk-specific IgE concentration in the first year of life can serve as a predictor of the persistence of milk allergy.

Background: Atopic dermatitis or atopic eczema is an itchy inflammatory skin condition with a predilection of the skin flexures. Most cases start in children although some have been reported in adults. Patients with moderate to severe disease refractory to topical corticosteroid or calcineurin inhibitors may require second-line treatment such as phototherapy or systemic immunosuppressants. Methotrexate therapy has been suggested to be a useful immunosuppressant in adult atopic dermatitis.

Objectives: To further determine the efficacy of low dose methotrexate therapy in adults with new-onset atopic dermatitis or with idiopathic eczema.

Methods: All adult patients with new-onset atopic dermatitis or idiopathic eczema treated by methotrexate in our clinics from 2004 to 2006 were included in the study. All had failed prolonged therapy with oral antihistamines and local corticosteroid creams. Methotrexate, 10–20 mg, was given orally once a week along with folic acid supplements 5 days a week. Additional therapies included predominantly emollients. During the entire treatment period the investigators made global assessments of the clinical response.

Results: Nine patients diagnosed with late-onset atopic dermatitis (n=6) or idiopathic eczema (n=3) were treated with methotrexate. All patients responded to the drug. The initial response was noted after 3–7 weeks. Six patients achieved complete remission after 3 months of methotrexate therapy and three patients had significant improvement. One patient's the condition worsened after achieving a complete response while on methotrexate and it was withdrawn completely. No serious adverse events were noted during treatment.

Conclusions: Low dose methotrexate is an effective therapeutic alternative for late-onset atopic dermatitis or idiopathic eczema in patients unresponsive to local and other systemic therapies.

Background: Atopic dermatitis is a common disease in infants and children and the incidence appears to be rising.

Objectives: To determine the presentation, allergies, and outcome among Israeli infants and children.

Methods: Children with atopic dermatitis referred to the allergy clinic at a regional pediatric center were evaluated for their medical history and their allergy. The allergic assessment was determined by utilizing skin prick tests and/or serum specific immunoglobulin E concentrations. The children were reexamined again for all parameters at the end of the follow-up period.

Results: Forty-six children with atopic dermatitis were studied, 27 males (58.7%) and 19 females (41.3%). A family history of allergy was found in 19 (41.3%). The median age at presentation was 17 months. Of the 46 children 33 (71.7%) revealed an allergy to one or more of the allergens. The most common combination was allergy to food and house-dust mites. The mean follow-up time was 64 months. By the age of 8 years full recovery was seen in 16 patients, half of whom recovered within 3.3 years from the date of presentation. The probability of complete remission was 58%, and for either complete or partial remission 76%. Upon reevaluation at the end of the follow-up period some patients lost their sensitivities, while others, who had been allergic to foods, became sensitive to house-dust mites and/or pollens.

Conclusions: Atopic dermatitis is an allergic problem in the northern region of Israel, as it is in other parts of the world. Food allergy and house-dust mites are major contributors to the evolution of eczema.
