Abstract
la obesidad es una patología de elevada prevalencia en nuestro medio, cuyas comorbilidades asociadas representan un gran reto para la salud pública global. La inyección de toxina botulínica intragástrica en animales y humanos se ha empleado como tratamiento para la obesidad. Su efecto incluiría el retraso del vaciamiento gástrico y la inducción de saciedad temprana, con la consiguiente disminución de la ingesta y la pérdida de peso. Materiales y métodos: se realizó una búsqueda bibliográfica en las bases de datos PubMed, Scopus y EMBASE, para el periodo comprendido entre 2000 y 2016. Se incluyeron los artículos que trataron las bases del tratamiento con toxina botulínica intragástrica en humanos, así como los diferentes estudios de intervención, aleatorizados o no. Resultados: se encontraron un total de 105 artículos y, utilizando los criterios de inclusión, se seleccionaron 10. De ellos, solo cuatro fueron aleatorizados y ocho duraron entre 8 y 24 semanas. En cuatro de los estudios, uno de ellos aleatorizado, se encontró una pérdida de peso significativa, que varió entre los 3,5 y los 11,8 kg. La mayor parte de los estudios halló un enlentecimiento del vaciado gástrico. Ningún estudio comunicó efectos secundarios de relevancia. Conclusión: la inyección de toxina botulínica intragástrica podría ser eficaz y segura en el tratamiento de la obesidad, pero son necesarios estudios bien diseñados, controlados con placebo, de largo seguimiento y adecuado tamaño muestral.
Obesity is a prevalent disease in our environment, which comorbidities suppose a great challenge to public health. Intragastric injection of botulinum toxin has been used as treatment for obesity, both in humans and animals. It acts by inhibiting gastric emptying and inducing early satiety, consequently reducing intake and finally achieving weight loss. A bibliographic search in PubMed, Scopus and EMBASE databases between 2000 and 2016 was carried out. Articles regarding the physiological basis of the treatment with intragastric injection of botulinum toxin in human were included, as well as interventional studies, randomised or not. A total of 105 articles were found and 10 were chosen according to our inclusion criteria. Of those, only 4 were randomised and 8 lasted between 8 and 24 weeks. In four of the studies, one randomised, a statistically significant weight loss was found which varied between 3.5 and 11.8 kg. Most of the studies found slowing of gastric emptying. None of them notified any significant side-effects. Intragastric injection of botulinum toxin could be useful and safe in the treatment of obesity but better designed, placebo-controlled, long term and with an adequate sample size studies are needed.
