ABSTRACT

Background:

The ultrarush protocol is an attractive approach in the buildup phase of venom immunotherapy (VIT-UR). However, the degree of risk of VIT-UR in children remains unknown. The objective of this study was to compare the safety of VIT-UR in children and adults.

Methods:

We performed a study based on prospectively gathered medical records of children and adults with hymenoptera venom allergy treated with VIT-UR in 3 allergy centers in Poland.

Results:

The study population comprised 134 children (mean [SD] age, 12.6 [3.7] years; males, 70.1%) and 207 adults (mean age, 42.4 [14.0] years; males, 47.8%). The number of children in the subgroups of bee venom (BV) allergy and wasp venom (WV) allergy were comparable, although sensitization to WV was more predominant in the adult group (70.1%). Skin reactivity to both venoms was more common in children than in adults (P<.001); however, children had higher concentrations of total IgE and specific IgE to BV (both P<.001). Systemic allergic reactions (VIT-SARs) occurred in 6.2% of the patients (3.7% in children and 7.7% in adults; nonsignificant). In adults, SARs occurred more frequently in patients treated with BV than WV extracts (21.4% vs 2.6%; P<.001). The same pattern was observed in children (7.2% vs 0%; P=.058). However, VIT-SARs to BV were less frequent in children than in adults (P=.034). Similarly, no significant relationship was noted between children and adults receiving WV VIT (2.6% vs 0%; nonsignificant). The severity of VIT-SAR did not differ between children and adults.

Conclusions:

VIT-UR is safer in children. Age below 18 is not a risk factor for VIT-SARs (AU)
RESUMEN

Introducción:

Los protocolos ultra rápidos son considerados de utilidad para realizar la fase de inicio de la inmunoterapia con venenos de himenópteros (VIT-UR). La seguridad de estos protocolos VIT-UR en los niños sigue siendo una cuestión debatida. El objetivo de este estudio fue comparar la seguridad de VIT-UR en niños y adultos.

Métodos:

Estudio prospectivo de seguimiento de la seguridad de la inmunoterapia en niños y adultos regularmente tratados con VIT-UR seguidos en tres unidades de alergia en Polonia.

Resultados:

En el estudio fueron incluidos un total de 134 niños (edad media de 12,6 años, SD 3,7; varones 70,1%) y 207 adultos (edad media 42,4 años, SD 14,0; 47,8% varones). El número de niños sensibilizados a veneno de abeja (BV) era comparable al de los sensibilizados a veneno de avista (WV), mientras que la sensibilidad al veneno de avispa prevaleció en el grupo de adultos (70,1%). Los niños con hipersensibilidad a venenos (HVA) mostraron menor reactividad cutánea a ambos venenos que los adultos con HVA (p <0,001) pero, por el contrario, en comparación con los adultos presentan concentraciones de IgE sérica total e IgE específica frente a BV (ambas p <0,001). Un 6,2% de todos los pacientes (3,7% de los niños y 7.7% de los adultos, NS) presentaron reacciones alérgicas sistémicas frente a la inmunoterapia con venenos (VIT-SAR). En los adultos, el SARS fueron más frecuentes en los pacientes tratados con BV que los tratados con WV (21,4% frente a 2,6% p <0,001). El mismo patrón se produjo en niños (7,2% vs 0%; p = 0,058). Sin embargo, las VIT-SAR frente a inmunoterapia con BV fueron menos frecuentes en los niños que en adultos (p = 0,034). Del mismo modo la frecuencia de reacciones frente a WV VIT fue menor en niños que en adultos pero sin diferencias significativas (0% vs 2,6%, NS). La gravedad de las VIT-SAR fue similar para niños y adultos.

Conclusiones:

Los protocolos VIT-UR son más seguros en los niños. Edad menor de 18 años no es un factor de riesgo de VIT-SAR (AU)
