ABSTRACT
Diversas enfermedades que constituyen problemas para la salud humana a nivel mundial, son el resultado de fallos en la homeostasis del cobre en la célula. El mecanismo de transporte del cobre no está completamente dilucidado; de ahí la necesidad de continuar profundizando en este tema. La presente revisión bibliográfica, sustentada en el análisis de 40 artículos científicos, describe los procesos de captación, distribución y eliminación del cobre en la célula; se refiere además a las enfermedades relacionadas con alteraciones en el metabolismo de dicho elemento y a su tratamiento, tales como, la enfermedad de Menkes y la de Wilson; y por último, a los estudios moleculares realizados en pacientes cubanos. Se concluye que el trabajo aporta información relevante que contribuye a la actualización y preparación del personal médico, respecto a estas afecciones a nivel molecular, celular y de organismo.
Several diseases which constitute a health problem for humans worldwide result from failure of copper cellular homeostasis. The mechanism of copper transportation in not completely defined therefore it is necessary to continue deepening on the topic. The present bibliographical review, based on the analysis of 40 scientific articles, describes the processes of copper catchment, distribution and elimination of copper in the cell; it refers, in addition to the diseases related to the metabolic disturbances of this element and its treatment, such as Menkes and Wilson diseases and lastly the molecular studies performed in Cuban patients. It is concluded that this work offers a significant information which contribute to the updating and preparation of the medical personnel regarding these illnesses at the molecular, cellular levels so as in the organism.
ABSTRACT
A Síndrome de Menkes ou tricopoliodistrofia é umadesordem neurodegenerativa de caráter recessivo, ligadaao cromossomo X, caracterizada por um distúrbiono transporte e metabolismo do cobre. O diagnósticoé sugerido pela tríade clássica dos fatores clínicos(atraso no desenvolvimento, degeneração neurológicae má formação dos cabelos) e com a demonstração daredução dos níveis séricos de cobre e ceruloplasmina.Relata-se o caso de dois irmãos, diagnosticados comSíndrome de Menkes, enfatizando-se ainda, a raridadedesse acontecimento e os tratamentos atuais de eficácialimitada.
Menkes syndrome or Twisted Hair Syndromeand trichopolyodistrophy is a rare, X-linked recessiveneurodegenerative disorder, characterized by adisturbance in copper metabolism. The diagnosis isclinically suggested by the classic triad of features(developmental delay, neurological degenerationand malformation of the hair) and with the demonstrationof reduction of serum copper and ceruloplasmin.We report on the case of two brothers, diagnosedwith Menkes syndrome, emphasizing also therarity of this event and the current treatments of limitedeffectiveness.
