Abstract
Introduction

The aim of this study was to evaluate discontinuation of quetiapine treatment in adolescents (12–18 years) in a 6-month naturalistic follow-up study and to assess the influence of distinct demographic and clinical factors on quetiapine discontinuation.

Material and methods

We performed a naturalistic 6-month follow-up study in 61 antipsychotic-naïve patients [39 boys (64%)] who initiated quetiapine treatment. The dependent variable was treatment discontinuation for any cause (continuation/discontinuation was a dichotomic variable). The independent variables were age, gender, race, duration of mental illness, Global Assessment of Functioning (GAF) score at treatment initiation, adverse effects in the first 16 days of treatment, the presence of involuntary movements before starting treatment, and abusive consumption or toxic dependency.

Results

Of the 61 patients participating in the study, 42 (68.9%) complied with quetiapine treatment for 6 months, while 19 (31.1%) discontinued the treatment (for any cause). The presence of Parkinson-like symptoms before starting treatment was a risk factor for discontinuation (Hazard ratio=8.3, P=.007).

Conclusions

Continuation/discontinuation of quetiapine was influenced by the presence of motor symptoms before treatment initiation, which therefore affected the patient's overall prognosis. Consequently, we recommend that the presence of motor symptoms be evaluated before treatment with antipsychotic drugs is started.

Resumen
Introducción

Este trabajo pretende evaluar la discontinuación del tratamiento con quetiapina en pacientes adolescentes (12–18 años) en un seguimiento naturalístico de 6 meses, así como valorar la influencia de distintos factores demográficos y clínicos sobre la suspensión de quetiapina.

Material y métodos

Seguimiento naturalístico a 6 meses de un total de 61 pacientes (39 varones (64,0%) naïve para antipsicóticos que iniciaron tratamiento con quetiapina. La variable dependiente fue la suspensión del tratamiento por cualquier causa (continuación/discontinuación en forma de variable dicotómica). Las variables independientes analizadas fueron: edad, género, raza, tiempo de evolución de enfermedad mental, puntuación GAF al inicio de tratamiento, síntomas adversos en los primeros 15 días de tratamiento, presencia de movimientos involuntarios antes del inicio del tratamiento, y consumo abusivo o dependencia de tóxicos.

Resultados

De los 61 pacientes que participaron en el estudio, 42 (68,9%) cumplieron el tratamiento con quetiapina durante los 6 meses de tratamiento, mientras que 19 (31,1%) discontinuaron el tratamiento (cualquier causa). La presencia de síntomas parkinsoniformes antes de comenzar el tratamiento constituyó un factor de riesgo para la discontinuación de la medicación (Hazard Ratio=8,3, p=0,007).

Conclusiones

La presencia de sintomatología motora antes de la primera prescripción de antipsicótico influye sobre la continuación/discontinuación de la medicación y, por tanto, sobre la evolución global del caso. Por ello, recomendamos evaluar la presencia de sintomatología motora antes del inicio del tratamiento farmacológico con antipsicóticos.
