Insect Venom Immunotherapy: Analysis of the Safety and Tolerance of 3 Buildup Protocols Frequently Used in Spain.

INTRODUCTION: Hymenoptera venom immunotherapy (VIT) is an effective treatment but not one devoid of risk, as both local and systemic adverse reactions may occur, especially in the initial phases. We compared the tolerance to 3 VIT buildup protocols and analyzed risk factors associated with adverse reactions during this phase. MATERIALS AND METHODS: We enrolled 165 patients divided into 3 groups based on the buildup protocol used (3, 4, and 9 weeks). The severity of systemic reactions was evaluated according to the World Allergy Organization model. Results were analyzed using exploratory descriptive statistics, and variables were compared using analysis of variance. RESULTS: Adverse reactions were recorded in 53 patients (32%) (43 local and 10 systemic). Local reactions were immediate in 27 patients (63%) and delayed in 16 (37%). The severity of the local reaction was slight/moderate in 15 patients and severe in 13. Systemic reactions were grade 1-2. No significant association was found between the treatment modality and the onset of local or systemic adverse reactions or the type of local reaction. We only found a statistically significant association between severity of the local reaction and female gender. As for the risk factors associated with systemic reactions during the buildup phase, we found no significant differences in values depending on the protocol used or the insect responsible. CONCLUSIONS: The buildup protocols compared proved to be safe and did not differ significantly from one another. In the population studied, patients undergoing the 9-week schedule presented no systemic reactions. Therefore, this protocol can be considered the safest approach.

Introducción: La inmunoterapia con veneno de himenópteros (ITV) es un tratamiento eficaz, pero no está desprovisto de riesgo ya que pueden ocurrir reacciones adversas locales o sistémicas, especialmente en las etapas iniciales del tratamiento. Comparamos la tolerancia de tres protocolos de inicio de ITV y analizamos los factores de riesgo asociados con las reacciones adversas que se produjeron en esta fase. Métodos: Se incluyeron 165 pacientes divididos en tres grupos según el protocolo de iniciación utilizado (3, 4 o 9 semanas). Evaluamos la gravedad de las reacciones sistémicas de acuerdo con el modelo de la Organización Mundial de Alergia. Analizamos los resultados mediante estadística descriptiva exploratoria y comparamos variables mediante el análisis de la varianza. Resultados: Cincuenta y tres pacientes (32%) experimentaron algún tipo de reacción adversa; 43 eran locales y 10 sistémicas. Las reacciones locales fueron inmediatas en 27 pacientes (63%) y tardías en 16 (37%). La gravedad de la reacción local fue leve o moderada en 15 pacientes y grave en 13. Las reacciones sistémicas fueron de grado 1 o 2. No encontramos asociación significativa entre la modalidad de tratamiento y la aparición de reacciones adversas locales o sistémicas o el tipo de reacción local. Solo encontramos una asociación estadísticamente significativa de la gravedad de la reacción local con el sexo femenino. En cuanto a los factores de riesgo asociados con las reacciones sistémicas en la fase de inicio, no se encontraron diferencias significativas en estos valores en función del protocolo utilizado o el insecto responsable. Conclusiones: Los protocolos de inicio comparados demostraron ser seguros y no difirieron significativamente entre sí. En la población estudiada, el protocolo de 9-semanas no produjo reacciones sistémicas, por lo que se puede considerar el protocolo más seguro (AU)
