СHROMOSOMAL REARRANGEMENTS AND ATOPIC DERMATITIS

Abstract

Objective. To determine the frequency and patterns of chromosomal abnormalities in patients with atopic dermatitis. Material and methods. 470 patients with torpid variant of atopic dermatitis were observed. The study included patients with established and recorded in the medical record diagnosis of atopic dermatitis, which has been confirmed in accordance with the diagnostic criteria of J. Hanifin and G. Rajka. Karyological study was performed to 47 patients with skin rash, interpreted as atopic dermatitis and various polysystemic lesions that could be associated with chromosomal aberrations. Results. According to results of karyotyping, 8 (17%) patients had a variety of deviations from the normal karyotype, which made 1.8%. In 3 cases the karyotype corresponding to syndrome Turner was detected. One patient had karyotype 46XY inv7 (gh ph). In 2 patients minor, differing in size inversion of chromosome 9 was detected. In 2 patients translocation forms of chromosomal rearrangements were identified. Conclusion. Given that the prevalence of chromosomal diseases in the population is 0.5%, the frequency of chromosomal rearrangements obtained in this study was 1.8%, significantly higher than general population figures. According to the results, we can recommend karyotyping for torpid form of atopic dermatitis particularly with concomitant pathology polysystemic or reproductive harm.
