title: [Role of Candida allergen in atopic dermatitis and efficacy of oral therapy with various antifungal agents].
abstract: We studied whether fungal allergens play a role in exacerbating the clinical symptoms of atopic dermatitis (AD). We found that the percentage of the patients who showed CAP-RAST positive (2 < or = score) to Candida albicans (Ca) was significantly higher in the patients with severe symptoms and high serum IgE level than those with mild symptoms and lower IgE. This was also true for the patients with CAP-RAST positive to Pityrosporum ovale (Po). AD patients with their symptoms localized to head and neck showed significantly higher tendency to have positive CAP-RAST (2 < or = score) to Ca and Po when compared to those with their eruption distributing to the extremities. We then evaluated the efficacy of oral therapy with antifungal agents in 140 cases of refractory AD with positive CAP-RAST to Ca. Good or excellent response was obtained in 60% with fluconazole, 35% with itraconazole, 31% with amphotericin B, 28% with nystatin. The present finding that amphotericin B and nystatin, both of which are not absorbed through intestine, were effective for approximately a third of the patients indicates that Ca in the intestine plays an important role in triggering AD symptoms. Fluconazole was more effective than amphotericin B and nystatin, suggesting that fungal colonizing in other parts of the body but the digestive tract also play a role in the exacerbation of AD symptoms.
