Huntington estudio con OCT en Argentina

Dres. Gatto, Etchverry, Persi, Cesarini y equipo

La enfermedad de Huntington (EH) es un trastorno neurodegenerativo genético, raro y progresivo que causa deterioro motor y cognitivo en pacientes de mediana edad. La tomografía de coherencia óptica (OCT) es una metodología no invasiva que analiza las capas de fibras nerviosas de la retina (RNFL) y podría reflejar procesos de neurodegeneración.
Luego de un estudio transversal con 14 pacientes enfermos que se sometieron a un OCT se demostró que la tomografía es una técnica rápida y no invasiva que puede investigarse en grandes cohortes de pacientes para evaluar su papel potencial como biomarcador en pacientes con EH.

Abstract


BACKGROUND:

Huntington's disease (HD) is a genetic, rare and progressive neurodegenerative disorder that causes motor and cognitive impairment in midlife patients. Although retinal damage was observed in animal HD models and in patients with other neurodegenerative diseases, we still need confirmation of impairment in HD patients. Optical coherence tomography (OCT) is a non-invasive methodology that analyses the retinal nerve fibre layers (RNFL) and could reflect processes of neurodegeneration.


METHODS:

A cross-sectional study with 14 HD patients who underwent a spectral domain OCT. Results were compared with a control group. Demographic data were also obtained.


RESULTS:

Temporal and superior RNFL sectors in HD showed a significant RNFL thinning compared with a control group. However, no differences were identified in mean total RNFL thickness between HD patients and controls.


CONCLUSIONS:

OCT is a rapid and non-invasive technique that can be investigated in larger cohorts of patients to assess its potential role as a biomarker in HD patients.
