Management of Dental-Oral Procedures in Patients With Hereditary Angioedema due to C1 Inhibitor Deficiency

Antecedentes: El angioedema hereditario por déficit de C1 Inhibidor (AEH-C1-INH) tiene unas importantes implicaciones para los profesionales de la salud bucodental ya que una cirugía dental puede desencadenar episodios de angioedema potencialmente mortales. El objetivo del estudio fue analizar la eficacia y seguridad de los andrógenos atenuados (AAs) y/o del concentrado plasmático de C1 Inhibidor derivado de humanos (pdhC1INH) para prevenir el desarrollo de angioedema de vías respiratorias superiores tras procedimientos odontoestomatológicos en pacientes con AEH-C1-INH. Material y métodos: Se revisaron los procedimientos odontoestomatológicos realizados en el Hospital Universitario La Paz. Se consideraron datos demográfi cos, tratamiento de mantenimiento, profi laxis pre-procedimiento, grado de severidad de la enfermedad y aparición de angioedema faringolaríngeo. Resultados: Veinticuatro pacientes (14H/10M) (edad media: 42,6 años) se sometieron a 66 procedimientos. La mayor parte se realizaron en pacientes con estadio grave (20 procedimientos) o moderado (26 procedimientos) de la enfermedad. Sólo nueve procedimientos se realizaron sin profilaxis de corto plazo (PCP). En tres procedimientos realizados sin PCP se desarrolló angioedema faríngeo leve ocurriendo en pacientes en estadio asintomático o mínimo de la enfermedad. Se encontró una asociación estadísticamente significativa entre desarrollo mínimo de angioedema de vías respiratorias superiores y ausencia de tratamiento de mantenimiento con AA, ausencia de incremento de dosis y no-administración de pdhC1INH preprocedimiento (Test exacto de Fisher: P=.002). Conclusiones: El aumento de dosis preprocedimiento de AA y/o la administración de pdhC1INH son buenas opciones para el manejo ambulatorio de los procedimientos odontoestomatológicos en pacientes con AEH-C1-INH. El tratamiento profiláctico con pdC1INH o el incremento de dosis de AA es recomendable antes de la manipulación dental, incluso en pacientes con estadio bajo en la escala de gravedad de la enfermedad (AU)

Background: Hereditary angioedema due to C1 inhibitor deficiency (HAE-C1-INH) has considerable implications for dental health care providers, since dental procedures may trigger severe and even life-threatening episodes. The aim of the present study was to analyze the efficacy and safety of premedication with attenuated androgens (AAs), plasma-derived human C1 esterase inhibitor concentrate (pdhC1INH), or both to prevent the development of upper airway angioedema after dental-oral procedures in patients with HAE-C1-INH. Material and Methods: All dental-oral procedures performed on patients with HAE-C1-INH who were followed up at La Paz University Hospital, Madrid, Spain were reviewed. Demographic data, maintenance treatment, preprocedure prophylaxis, disease severity, and occurrence of upper airway angioedema were recorded. Results: Twenty-four patients (14 male/10 female; mean age, 42.6 years) underwent 66 procedures. Most procedures were performed on patients with severe HAE-C1-INH (20 procedures) or moderate HAE-C1-INH (26 procedures). Only 9 procedures were performed without short-term prophylaxis. Mild upper airway angioedema developed after 3 procedures performed without short-term prophylaxis in patients with minimal or asymptomatic HAE-C1-INH. A statistically significant association was found between development of mild postprocedure upper airway angioedema and lack of maintenance treatment with AA, lack of increased dose of preprocedure AA, and failure to administer preprocedure pdhC1INH (P=.002, Fisher exact test). Conclusions: Increased doses of prophylactic AA, administration of pdhC1INH, or both were good options for ambulatory management of dental-oral procedures in patients with HAE-C1-INH. Prophylaxis with pdC1INH or increased doses of AA is advisable before dental-oral procedures, even in patients with low disease severity (AU)

Changes in IL-10 and specific antibodies associated to successful Dermatophagoides pteronyssinus immunotherapy in children during the first year of treatment

Background: Allergen-specific immunotherapy (SIT) is a long-term treatment of respiratory allergy. Objective: To look for early predictors of the effectiveness of Dermatophagoides pteronyssinus SIT. Methods: A prospective multi-centre study was carried out in Spain. Children with D. pteronyssinus rhinitis or asthma were invited to participate. The study was divided into times: T0 (recruitment); T1 (inclusion); T2 a-f (immunotherapy times) and T3 (the end of study). Efficacy of SIT was assessed by clinical scores, visual analogue scales (VAS) and lung function tests. We performed D. pteronyssinus skin tests at T1 and T3, and determined specific serum IgE, IgG4 and IL-10 at T1, T2f and T3.Data were analysed using Mann–Whitney and Kruskal–Wallis tests, compared using Wilcoxon and Chi-square tests, and correlated to Spearman test. All tests had a significance level of 0.05. Results: Thirty-eight children completed the study. At T1 all had rhinitis and 34 also had asthma. At T3, 30 patients had improved, six experienced no changes and two worsened. Improvement was associated to FEV1/FVC and VAS improvement; to a reduction in D. pteronyssinus skin prick test; to a progressive increase in serum levels of D. pteronyssinus IgE, and D. pteronyssinus, Der p1 and Der p2 IgG4. IL-10 levels showed an early increase at T2f (the end of initial build-up immunotherapy phase), and then a reduction at T3 (the end of a year of immunotherapy).Improvement associated to an early increase in IL-10 and was correlated with VAS and specific IgG4 evolution(AU)
