Abstract

INTRODUCTION:

Recent data supported the presence of T helper 2 dominance in the immune processes of Graves' disease and allergic diseases. A common role of regulatory T cells in the antigen- (or allergen-) specific immune responses was also demonstrated.

AIMS:

To study whether allergic events may play a role in the initiation or progression of autoimmune Graves' disease. The occurrence of seasonal allergy may explain the fluctuation in the onset of Graves' disease.

METHODS:

The presence of specific IgE levels against inhalative allergens was investigated in 327 patients with thyroid disease (Graves' disease, Hashimoto's thyroiditis, euthyroid goitre). Western blot method was used for the measurement of allergen-specific IgE levels with densitometric evaluation.

RESULTS:

Allergic sensitization was found in 88 cases (58%) for Graves' disease, 51 cases (46%) for Hashimoto's thyroiditis and 31 cases (55%) for euthyroid goitre. According to allergens, significant difference was demonstrated by Penicillium notatum, Dermatophagoides farinae, alder - rye (pollens) between Graves' disease (depending ophthalmopathy) and euthyroid goitre. In the four groups based on allergen seasonality, the month of the onset in Graves' disease was associated with the season of early tree and mugwort allergy (P < 0.019 between Graves' disease and Hashimoto's thyroiditis). The number of cases, in whom the onset of Graves' disease in a given month was similar to the month of allergic season, was 17 cases vs 7 cases with Hashimoto's thyroiditis (P < 0.028).

CONCLUSIONS:

The allergic sensitization was more frequent in Graves' disease, and the allergic seasonality may explain the fluctuation in the onset of Graves' disease.
