colColagernopatias y psoriasis.

Autores: La asociación de diferentes colagenopatias con psoriasis la hemos visto con cierta frecuencia en nuestra estadística.
Presentamos cuatro pacientes con una colagenopatia (lupus, dermatomiositis y esclerodermia) y psoriasis.
Es importante recordar que tanto las colagenopatias como la psoriasis son enfermedades autoinmunes con genesis multifactorialen las cuales se combinan fenómenos genéticos, inmunológicos e ambientales con algunos lazos en común.
El interés de esta comunicación radica en que la superposición de estas enfermedades puede en algunos casos dificultar el diagnostico, agravar el pronostico o complicar su tratamiento.

|Nov. 11, 2000 -- Changes in one gene have been discovered that are shared by three common autoimmune diseases -- the skin condition psoriasis as well as systemic lupus |
|erythematosus (SLE) and rheumatoid arthritis (RA). The genetic changes involve a gene called Runx-1.|
|What is Runx-1? |
||
|Runx-1 is a protein that acts as a transcription factor. It controls when genes are switched on or off. Runx-1 does so by binding to regulatory sequences -- specific sequences of|
|DNA -- that are close to the genes they regulate. These DNA sequences, called Runx-1 binding sites, are scattered throughout the human genome, wherever there is a gene under the|
|control of Runx-1. |
|Runx-1 stands for runt-related transcription factor 1. Runx-1 is also called AML1 because it is also altered in a form of acute myeloid leukemia, but that is a very different |
|story, one to be told another...
