ABSTRACT

A doença de Addison é uma endocrinopatia rara, de etiologia autoimune. É caracterizada por défice na secreção de glicocorticoides e mineralocorticoides. A esclerose múltipla consiste em patologia neurológica, de origem autoimune, que resulta na desmielinização da bainha de mielina. O objetivo deste relato foi demonstrar a associação rara entre essas duas patologias e suas possíveis relações imunológicas. A paciente analisada é do sexo feminino, 41 anos, portadora de esclerose múltipla, que posteriormente foi diagnosticada com insuficiência adrenal primária. (AU)


Addison's disease is a rare endocrinopathy of autoimmune etiology. It is characterized by a secretion's deficit of glucocorticoids and mineralocorticoids. Multiple sclerosis is a neurological pathology of autoimmune origin, which results in demyelination of the myelin sheath. The purpose of this report is to demonstrate the uncommon association between these two pathologies and their possible immunological relationships. The analyzed patient is a woman, 41 years old, with multiple sclerosis, who was later diagnosed with primary adrenal insufficiency. (AU)

ABSTRACT

OBJECTIVE: To search for mutations in DAX1/NR0B1A gene in siblings to establish the molecular etiology of the adrenal hypoplasia congenita (AHC), a rare potentially life-threatening disorder. CASE REPORT: We describe two siblings who presented with salt-wasting syndrome in the newborn period and received hormonal replacement for primary adrenal insufficiency. A diagnostic hypothesis of AHC was suspected because the children maintained, during hormonal treatment, low plasma 17-OH progesterone (17-OHP) and androgens, despite high ACTH levels. RESULTS: DAX1 gene was studied by molecular analysis, which showed a mutation, confirming the diagnosis in the siblings and a heterozygous state in the mother. Direct sequencing of DAX1 revealed an insertion of an adenine base (c1382-1383 A ins), which lead to a pMet461Asp substitution. CONCLUSION: A novel frameshift mutation of DAX1 gene, which established the molecular etiology of the AHC in the siblings, was identified. Obtaining a precise genetic diagnosis of this adrenal disorder, which, sometimes, cannot be confirmed only by clinical aspects, may have important implications for the long-term management of the disease.


OBJETIVO: Pesquisar mutações no gene DAX1/NR0B1A em dois irmãos com suspeita de hipoplasia adrenal congênita (HAC), rara doença potencialmente fatal, para estabelecer sua etiologia molecular. RELATO DOS CASOS: São apresentados os relatos de dois irmãos com síndrome perdedora de sal no período neonatal que receberam terapia de reposição hormonal para insuficiência adrenal primária. O diagnóstico de HAC foi suspeitado porque as crianças mantiveram, durante o tratamento hormonal, níveis plasmáticos reduzidos de 17-OH-progesterona e andrógenos ao lado de níveis elevados de ACTH. RESULTADOS: A análise molecular do gene DAX1 mostrou a mutação, confirmando o diagnóstico nos irmãos e o estado heterozigoto da mãe. No sequenciamento direto do DAX1 foi encontrada inserção de uma adenina (c1382-1383 A ins), levando à substituição pMet461Asp. CONCLUSÃO: Uma nova mutação da fase de leitura no gene DAX1 foi identificada, estabelecendo a etiologia molecular da HAC nos dois irmãos. Um diagnóstico genético preciso deste distúrbio adrenal, frequentemente não confirmado apenas pelos aspectos clínicos, pode ter importantes implicações para o manuseio em longo prazo da doença.

ABSTRACT

Primary adrenal insufficiency is an uncommon disease which has worldwide distribution. The commonest cause in underdeveloped countries is tuberculosis followed by autoimmune destruction of the adrenal gland. We report a case of a 15 years boy who had congenital adrenal insufficiency associated with achalasia of the cardia and deficient tear secretion.
