Hipocalcemia Crónica por Anticorpos Anti-Recetor do Cálcio

Abstract

Introdução: O hipoparatiroidismo cursa com hipocalcemia e é mais frequentemente registado após cirurgia cervical. A etiologia autoimune é mais rara e difícil de diagnosticar.Caso clínico: Mulher, 52 anos, sem antecedentes pessoais, medicamentosos ou familiares relevantes, referenciada por hipocalcemia e calcificação dos núcleos da base, detetados no decurso de investigação de quadro de mialgias. Além de hipocalcemia (4,6 mg/dL), foi verificada hiperfosfatemia (8,7 mg/dL), hormona paratiroideia indetetável, calciúria, fosfatúria e magnesúria baixas. A análise molecular do gene CaSR excluiu mutações germinais. A pesquisa de anticorpos anti-receptor sensível do cálcio (anti-CaSR) foi positiva. Atualmente está assintomática e normocalcémica sob terapêutica com cálcio e vitamina D.Discussão: Embora rara, a hipocalcemia por hipoparatiroidismo autoimune deve ponderar-se em adultos sem antecedentes de cirurgia cervical, medicação hipocalcemiante, história familiar ou fenótipo sugestivo de doença genética. Hormona paratiroideia diminuída ou indetetável exclui pseudohipoparatiroidismo e a positividade para anti-CaSR confirma o diagnóstico.Palavras-chave: Hipocalcemia; Hipoparatiroidismo; Receptores de Detecção de Cálcio.
