Abstract
Las psicosis (o trastornos psicóticos) son un grupo de trastornos del neurodesarrollo en cuyas etiología, fisiopatología y pronóstico convergen factores genéticos y ambientales. Varias líneas de investigación sugieren que la compleja fisiopatología de las psicosis incluye, entre otros mecanismos, un envejecimiento celular acelerado. En los últimos años se han producido avances significativos en la identificación de las vías moleculares relacionadas con el envejecimiento en personas con trastornos psicóticos. Los telómeros son los biomarcadores genéticos de envejecimiento celular o senescencia celular más estudiados y utilizados. Hay pocos estudios sobre el envejecimiento celular medido según el cambio de la longitud de telómeros de los leucocitos de personas en los primeros años de enfermedad tras un primer episodio psicótico (PEP), y los trabajos que hay tienen resultados contradictorios. Hasta el momento no existe ningún estudio longitudinal que analice el cambio en la longitud de los telómeros en esta población y que, además, describa el papel que tienen factores como la edad, el sexo, el tratamiento antipsicótico y la gravedad de la enfermedad en este cambio...
Psychoses (or psychotic disorders) are a group of neurodevelopmental disorders in which genetic and environmental factors converge. Several lines of research suggest that the complex pathophysiology of psychosis includes, among other mechanisms, accelerated cellular aging. In recent years there have been significant advances in the identification of molecular pathways related to aging in people with psychotic disorders. Telomeres are the most studied and used genetic biomarkers of cellular aging or cellular senescence. There are few studies on cellular aging as measured by telomere length change in leukocytes from people in the first years of illness after a first psychotic episode (FEP), and those that exist have contradictory results. So far, there is no longitudinal study that analyzes the change in telomere length in this population that also describes the role of such factors as age, sex, antipsychotic treatment and severity of illness...
