[Show abstract][Hide abstract] ABSTRACT: The prevalence of fish allergy among 11 atopic children with elevated levels of specific immunoglobulin (Ig) E for cod was determined. None of the children had a history of fish allergy. All of the children had asthma and allergic rhinitis and 5 of them had also atopic dermatitis. The children underwent allergy skin tests (codfish, tuna, catfish, salmon, flounder, and bass), specific IgE tests (salmon, trout, tuna, eel, and mackerel), and food challenge tests. Skin tests in cod-specific IgE-positive children were positive for codfish in 4 children, tuna in 2, catfish in 2, salmon in 6, flounder in one, and bass in 2. Three children had elevated specific IgE for salmon, 5 for trout, 8 for tuna, 4 for eel, and 4 for mackerel. Oral fish challenge with 10 g of fish did not result in positive reaction in any of the children. In conclusion, a positive food challenge test provided the only definitive confirmation of fish allergy, whereas positive allergy skin tests or positive specific IgE tests were less reliable. Skin tests and in vitro specific IgE assays were not correlated with clinical symptoms of fish allergy, and the results of these 2 tests did not correlate with each other in this study.

[Show abstract][Hide abstract] ABSTRACT: Childhood serum sickness is a rare allergic disease that follows the administration of a foreign antigenic material, most commonly caused by injecting a protein or haptenic drug. The disease is a type III hypersensitivity reaction mediated by deposits of circulating immune complexes in small vessels, which leads to complement activation and subsequent inflammation. The clinical features are fever, cutaneous eruptions, lymphadenopathy, arthralgias, albuminuria, and nephritis. Serum sickness is an acute self-limited disease. We report a 3-year-old child who presented with fever and a rash; an invasive bacterial infection was strongly suspected. He was therefore given penicillin and gentamicin and responded well. At day 4 after admission, he developed a serum sickness reaction and showed symptoms of arthralgias, generalized edema, purpura, and gross hematuria. The white blood cell count was 12 190/mm3 with 7% eosinophils. Urinalysis revealed red blood cell above 100 per high power field, white blood cell 10 to 15 per high power field, and proteinuria. The antibiotics were discontinued and hydrocortisone (20 mg/kg/d), diphenhydramine HCl (4 mg/kg/d), aspirin (66 mg/kg/d) was administered, plus 1 dose of epinephrine (0.01 mL/kg) administered intramuscularly. On day 7, the 3rd day after withholding antibiotics, his condition dramatically improved. The clinical symptoms resolved progressively and his urinalysis returned to normal.
