Trauma reactivation under propranolol among traumatized Syrian refugee children: preliminary evidence regarding efficacy
Abstract
Background: There is a dearth of therapeutic solutions for traumatized young patients. Trauma reactivation conducted under the influence of the reconsolidation blocker propranolol (Reconsolidation Therapy) is a simple, cost-effective treatment option that has some promising initial results in adults suffering from posttraumatic stress disorder (PTSD). Objective: To explore the usefulness of this novel treatment in children. The primary outcome was the reduction of PTSD symptoms at the end of treatment, while secondary outcomes included reduction in anxiety and in depressive symptoms. Method: An open-label clinical trial was conducted in a refugee camp in Syria, investigating the safety and efficacy of this therapeutic strategy in 117 children suffering from enduring PTSD symptoms. Participants received propranolol 90 minutes before briefly recalling (i.e. reactivating) a single personal traumatic memory, for 5 consecutive days. Self-reported anxiety, depressive, and PTSD symptoms were assessed at baseline, as well as 4 and 13 weeks after treatment. Results: A significant, clinically meaningful symptom reduction was observed at all post-treatment measurement times vs. baseline. More specifically, between baseline and the 13-week follow-up we observed a 64% PTSD symptoms reduction (d = 2.71). In a similar vein, we obtained a 39% symptoms reduction for depressive symptoms (d = 1.01). The general anxiety symptoms improved, but eventually returned to prior level, probably because of the deteriorating living conditions in the camp. Conclusions: This therapy appeared as a potentially safe and useful treatment strategy for children suffering from PTSD symptoms, warranting replication studies using stronger study designs. The social acceptability and ease of implementation of the treatment should also be noted.
Introducción: Existe una escasez de soluciones terapéuticas para pacientes jóvenes traumatizados. La reactivación del trauma conducida bajo los efectos del propanolol bloqueador de reconsolidación (Terapia de Reconsolidación) es una opción de tratamiento simple, costo-efectiva, que tiene algunos resultados iniciales prometedores en adultos que sufren del trastorno de estrés postraumático (TEPT).Objetivos: Explorar la utilidad de este novedoso tratamiento en niños. El resultado primario fue la reducción de los síntomas de TEPT al final del tratamiento, mientras que los resultados secundarios incluyeron la reducción de los síntomas ansiosos y depresivos.Métodos: Se condujo un estudio clínico abierto en un campo de refugiados en Siria, investigando la seguridad y eficacia de esta estrategia terapéutica en 117 niños que permanecían con síntomas de TEPT. Los participantes recibieron propranolol 90 minutos antes de recordar brevemente (es decir, reactivación) un único recuerdo personal traumático, por 5 días consecutivos. Se evaluó los síntomas de ansiedad, depresión y TEPT auto-reportados, tanto al inicio, como a las 4 y 13 semanas después del tratamiento.Resultados: Se observó una reducción sintomática significativa, clínicamente importante en todas las mediciones post tratamiento versus el nivel basal. Más específicamente, observamos un 64% de reducción de síntomas de TEPT entre el nivel basal y el seguimiento en la semana 13 (d = 2.71). De forma similar, obtuvimos un 39% de reducción de los síntomas depresivos (d =1.01). Los síntomas generales de ansiedad mejoraron, pero retornaron a sus niveles previos al final, probablemtente por las condiciones de vida deteriorantes en el campo de refugiados.Conclusiones: Esta terapia pareciera ser una estrategia de tratamiento potencialmente segura y útil en niños que sufren síntomas de TEPT, justificando estudios de replicación que usen diseños más estrictos. Se debería hacer notar también la aceptabilidad social y la fácil implementación del tratamiento.
引言: 针对遭受创伤的年轻患者的治疗方案有所欠缺。在再巩固阻滞剂普萘洛尔 (再巩固疗法) 影响下进行的创伤再激活是一种简单划算的治疗选择, 在创伤后应激障碍 (PTSD) 成年患者中取得了一些有希望的初步结果。目标: 探究此新颖治疗方法在儿童中的有效性。主要结果是治疗结束时PTSD症状的减轻, 次要结果包括焦虑和抑郁症状的减轻。方法: 在叙利亚一个难民营中进行了一项开放性临床试验, 考查此治疗策略对于117名有持久性PTSD症状的儿童的安全性和有效性。参与者连续5天在简要回忆 (即再激活) 个人创伤记忆的90分钟前摄入普萘洛尔。在基线及治疗后4周和13周时, 对焦虑, 抑郁和PTSD症状进行自评式评估。结果: 与基线相比, 在治疗后所有测量时间上均观察到显著且有临床意义的症状减轻。更具体地说, 在基线和13周的随访之间, 我们观察到PTSD症状减轻了64% (d = 2.71) 。同样, 我们发现抑郁症状减轻了39% (d = 1.01) 。总体焦虑症状有所改善, 但最终恢复到之前的水平, 这可能是营地生活条件恶化所致。结论: 对于有PTSD症状的儿童, 这种疗法似乎是一种潜在安全有效的治疗策略, 保证了更强研究设计的重复性研究。也应注意该治疗方法的社会可接受性和易于实施性。.
