DERMATOSE BOLHOSA IGA LINEAR EM DOENTE COM COLITE ULCEROSA – UMA ASSOCIAÇÃO RARA MAS ESTABELECIDA
Resumo
A associação da dermatose bolhosa IgA linear (DBAL) com colite ulcerosa (CU) está descrita, embora a sua origem desta associação não esteja bem definida. Descreve-se o caso de uma doente de 41 anos, com CU diagnosticada há 6 anos e agravamento há 2 meses, referenciada devido a bolhas tensas, pruriginosas, dispersas no tegumento, com 1 mês de evolução. Referidos antecedentes de diabetes gestacional, depressão reactiva e hipertensão arterial. Medicada com mesalazina desde há 1,5 anos, bisoprolol, mexazolam e drospirenona/etinilestradiol. A biopsia cutânea mostrou bolha na junção dermoepidérmica, com infiltrado inflamatório polimórfico dérmico. A imunorreactividade linear de IgA confirmou o diagnóstico de DBAL. Foi iniciada prednisolona e dapsona com boa resposta clínica. A etiologia desta associação poderá dever-se à reactividade cruzada do idiotipo IgA presente na CU contra os antigénios dermoepidérmicos. Não se pode excluir totalmente a imputabilidade da mesalazina na indução de uma forma de DBAL associada a fármacos.
