RESUMEN
El STAR*D es la más grande investigación que se ha realizado sobre el tratamiento de la depresión mayor. El objetivo del estudio fue determinar qué tratamientos sucesivos resultaban más efectivos en caso de falta de respuesta o intolerancia a un inhibidor selectivo de la recaptación de serotonina. Sus hallazgos principales fueron 1) La tasa de remisión en monoterapia es baja; 2) No hubo diferencias en cambiar a otro IRSS, a un dual o a otro mecanismo de acción; 3) Las potenciaciones funcionaron posiblemente un poco mejor, en pacientes que tenían respuesta parcial y buena tolerancia al citalopram. Leve ventaja del bupropión sobre la buspirona y mejor tolerabilidad y facilidad de manejo de la T3 sobre el litio; 4) No hubo diferencias entre agregar o cambiar a psicoterapia y medicación en pacientes que no responden al citalopram; la medicación fue más rápida como potenciación; 5) Todos los caminos que se tomaron dieron en general resultados similares; 6) La probabilidad de remitir va decreciendo a medida que se suceden tratamientos, especialmente a partir del tercero, mientras que las chances de recaer aumentan; 7) La remisión tiene menores posibilidades de recurrencia que la simple respuesta.
ABSTRACT
STAR*D, the biggest investigation ever conducted on the treatment of major depression, was aimed to determine prospectively which of several treatments is the most effective "next step" for patients who do not reach remission with an initial or subsequent treatment or who cannot tolerate the treatment. Its main findings show that 1) Monotherapy remission rates are low; 2) There were no outcome differences in changing to another SSRI, to a dual reuptake inhibitor o to another mechanism of action. 3) Augmentation strategies worked perhaps better in patients with partial response and good citalopram tolerability. There was a slight advantage of bupropion over buspirone. T3 had better tolerability and was easier to use than lithium; 4) There was no difference between cognitive therapy as a switch or as augmentation strategy versus medication as a switch or augmentation strategy. Antidepressants were faster in augmentation. 5) There were no statistical differences in remission rates among any of the medications compared in this study; 6) Remission rates drop level after level, more substantially after two failed treatments. Conversely, recurrence rates rise progressively; 7) Patients who achieve remission are less likely to relapse than patients who have only responded.
