RESUMO
Background: Hereditary angioedema type 1 (HAE1) is an autosomal dominant disorder, characterized by quantitative and qualitative deficiency of C1 inhibitor, excessive production of bradykinin and causing recurrent angioedema in varying degrees of severity that affects quality of life and life itself. from the patients. Lanadelumab is a human monoclonal antibody, a specific inhibitor of plasma kallikrein, approved for long-term prophylaxis of HAE1. Case report: A 59-year-old female patient, diagnosed with HAE 1 since November 1987, without therapeutic response to danazol, fresh frozen plasma, or C1 inhibitor derived from intravenous plasma, requiring 3 to 9 monthly vials of icatibant acetate due to angioedema. laryngeal, cutaneous and visceral with highly altered quality of life indices. Lanadelumab 300 mg subcutaneously every 14 days was started. At the start of treatment, the AECT1 score was 1 point; AE-Qol2: 57 points, AAS3: 32 points, being followed up at 5, 10 and 12 months. After one year of treatment, the records showed an AECT1 of 19 points; AE-Qol2: 36 points and AAS3: 5 points. The requirement for icatibant acetate has been no more than 3 vials per month. Conclusion: In accordance with the literature, lanadelumab offered a significant decrease in angioedema activity and a significantly positive impact on the pa- tient's quality of life, confirming that lanadelumab is an effective option for long-term HAE prophylaxis. .
Antecedentes: El angioedema hereditario tipo 1 (AEH1) es un trastorno autosómico dominante, caracterizado por la carencia cuantitativa y cualitativa del C1 inhibidor, producción excedida de bradicinina y causar angioedema recurrente en diversos grados de severidad que afecta la calidad de vida y la vida misma de los pacientes. Lanadelumab es un anticuerpo monoclonal humano, inhibidor específico de la calicreína plasmática, aprobado para profilaxis a largo plazo del AEH1. Reporte de caso: Paciente femenino de 59 años, con diagnóstico de AEH 1 desde noviembre de 1987, sin respuesta terapéutica a danazol, plasma fresco con- gelado ni C1 inhibidor derivado del plasma intravenoso, requerimiento de 3 a 9 ampolletas mensuales de acetato de icatibant por angioedema laríngeo, cutáneo y visceral con índices de calidad de vida sumamente alterada. Se inició lanadelumab 300 mg cada 14 días subcutánea. Al inicio del tratamiento el puntaje de AECT1 fue de 1 punto; AE-Qol2:57 puntos, AAS3: 32 puntos, realizándose un seguimiento a los 5, 10 y 12 meses. Al año de tratamiento, los registros mostraron un AECT1 de 19 puntos; AE-Qol2: 36 puntos y AAS3: 5 puntos. El requerimiento de acetato de icatibant ha sido a no más de 3 ampolletas por mes. Conclusión: En concordancia a la literatura, lanadelumab ofreció al caso, una importante disminución de la actividad del angioedema y un impacto significativa- mente positivo en la calidad de vida de la paciente, constatando que lanadelumab es una opción eficaz en la profilaxis a largo plazo del AEH.

BACKGROUND: Even though there are multiple options for the treatment of asthma, there still exists a fair group of patients with difficult-to-control asthma. We describe for the first time the real-world effects of three-year omalizumab treatment on patients with difficult-to-control asthma, seen in a social security hospital in a Latin American country. METHODS: Difficult-to-control asthmatic patients from the out-patient clinic of a regional hospital were recruited to receive a three-year omalizumab course. Efficacy parameters were asthma control test (ACT) score; FEV1; daily beclomethasone maintenance dose; and unplanned visits for asthma exacerbations (emergency room (ER), hospitalisations, intensive care). RESULTS: 52 patients were recruited, 47 completed the three-year treatment (42 female, 15-67 years, mean age 43.5). Comparing efficacy parameters of the year before omalizumab with the 3rd year of omalizumab: mean ACT improved from 12.4 to 20.5, mean FEV1 from 66.3% (standard deviation (SD) 19.1%) to 88.4% (SD 16.2%) of predicted, while mean beclomethasone dose reduced from 1750 to 766 mcg/day and there was a significant reduction in patients experiencing ER visits (from 95% to 19%, p<0.0001), hospitalisation (38% to 2%, p<0.0001) and intensive care (4% to 0, NS). Five patients discontinued omalizumab, two because of an adverse event (anaphylaxis, severe headache, both resolved without sequelae). CONCLUSION: Omalizumab improved most clinical parameters of Mexican patients with difficult-to-control asthma. Especially the rates of ER visits and hospitalisation were significantly reduced, thus reducing costs. Omalizumab was generally well tolerated.
