Abstract
[Resumen] Objetivo. El uso de sirolimus en anomalías vasculares es una indicación especial no autorizada en ficha técnica. El objetivo de este
estudio es incrementar la evidencia del empleo por vía oral o tópica de
sirolimus en esta indicación en población pediátrica.
Método. Estudio observacional retrospectivo de pacientes menores de 18 años tratados con sirolimus oral o tópico para anomalías
vasculares recogiendo: diagnóstico y ubicación de lesiones, forma de
administración y dosificación de sirolimus, niveles sanguíneos de fármaco en los pacientes con tratamiento oral, duración del tratamiento,
respuesta y toxicidad.
Resultados. Se incluyeron 18 pacientes (7 con tratamiento oral y
11 tópico). Con sirolimus oral, la tasa de respuesta global fue 85,7%.
Se interrumpió sirolimus en 2 casos: por resolución completa y por
progresión. El 57,1% experimentó algún efecto adverso, en su mayoría
leves; siendo la dislipemia el efecto adverso más frecuente. La monitorización de niveles sanguíneos fue empleada en todos los pacientes
para el ajuste de dosis. Con el tratamiento tópico, la tasa de respuesta
global fue 72,7%. Se interrumpió sirolimus en 3 casos: progresión en
2 casos y estabilidad en 1. El 27,3% experimentó algún efecto adverso,
siendo el prurito el más frecuente.
Conclusiones. Los resultados favorables del tratamiento con sirolimus en nuestros pacientes parecen confirmar la efectividad y seguridad
del fármaco en anomalías vasculares y lo posicionan como una opción
terapéutica en pacientes pediátricos. Aun así, parece necesaria mayor
investigación que trate de aclarar, entre otros, el régimen óptimo del
tratamiento, la duración del mismo y los potenciales efectos adversos
a largo plazo.
[Abstract] Objective. The use of sirolimus in vascular anomalies is a special indication not authorized in its data sheet. The objective of this study was to increase the evidence of oral or topical use of sirolimus for this indication in the pediatric population. Materials and methods. An observational, retrospective study of patients under 18 years of age treated with oral or topical sirolimus for vascular anomalies was carried out. Diagnosis and location of lesions, administration route and dosage of sirolimus, blood levels of sirolimus in patients who received oral treatment, treatment duration, response, and toxicity were collected. Results. 18 patients –7 with oral treatment and 11 with topical treatment– were included. With oral sirolimus, the overall response rate was 85.7%. Sirolimus was discontinued in 2 cases –as a result of full resolution and progression. 57.1% of patients had adverse effects, most of which were mild. Dyslipidemia was the most frequent adverse effect. Blood levels were monitored in all patients for dose adjustment purposes. With topical treatment, the overall response rate was 72.7%. Sirolimus was discontinued in 3 cases –due to progression in 2 cases and to stability in 1. 27.3% of patients had adverse effects, with itching standing out as the most frequent one. Conclusions. The favorable results of sirolimus treatment in our patients seem to confirm its effectiveness and safety in vascular anomalies, which make it stand as a therapeutic option in pediatric patients. However, further research is required to establish the optimal treatment regimen, treatment duration, and potential long-term adverse effects.
