RESUMEN
Resumen La enfermedad de Menkes es una patología neurodegenerativa y letal debida a mutaciones génicas de la enzima ATP-7A trasportadora de cobre; se manifiesta por síntomas neurológicos y alteraciones del tejido conectivo de severidad variable. El uso subcutáneo oportuno de histidinato de cobre (Cu-His) es determinante en la calidad de vida. Se reportan las primeras experiencias en México en la síntesis y uso seguro de Cu-His en tres casos en los que corroboramos hipocupremia e hipoceruloplasminemia. Bajo asesoramiento del Hospital for Sick Children, Toronto, Canadá, elaboramos una solución de 500 µg/mL. En los tres casos aplicamos 250 µg de Cu-His, sin efectos indeseables relevantes durante 30 días y observamos las siguientes determinaciones séricas de cobre (Cu en µg/L) y ceruloplasmina (Cp en mg/dL) caso 1, Cu días 0 y 30, 8 y 504 µg/L; Cp días 0 y 30, 4 y 10.75 mg/dL; caso 2, Cu días 0 y 30, < 50 y 502, µg/L; Cp días 0 y 30, 2 y 15 mg/dL; caso 3, Cu días 0 y 30, 3 y 84.2 µg/L; Cp días 0 y 30, 4 y 10.7 mg/dL. En México es posible la síntesis segura de Cu-His y tratar la enfermedad de Menkes, la cual debe ser intencionalmente buscada.
ABSTRACT
Abstract Menkes disease is a neurodegenerative and lethal pathology caused by gene mutations of the copper-transporting ATP-7A enzyme; it manifests itself by neurological symptoms and connective tissue changes of varying severity. Timely subcutaneous use of copper histidinate (Cu-His) is determinant for quality of life. We report the first experiences in Mexico on Cu-His synthesis and its safe use in 3 cases where hypocupremia and hypoceruloplasminemia were corroborated. With advice of the Hospital for Sick Children of Toronto Canada, we prepared a 500 µg/mL solution. In all three cases were 250 µg of Cu-His applied without relevant undesirable effects for 30 days. Serum copper (Cu, expressed in µg/L) and ceruloplasmin (Cp, in mg/dL) were determined case 1, Cu days 0 and 30, 8 and 504 µg/L; Cp days 0 and 30, 4 and 10.75 mg/dL; case 2, Cu days 0 and 30, <50 and 502 µg/L; Cp days 0 and 30, 2 and 15 mg/dL; case 3, Cu days 0 and 30, 3 and 84.2 µg/L; Cp days 0 and 30, 4 and 10.7 mg/dL. In Mexico, it is possible to safely synthesize Cu-His and treat MD, which must be intentionally sought.
