Safety of anti-CGRP monoclonal antibodies in patients with migraine during the COVID-19 pandemic: Present and future implications.

BACKGROUND AND OBJECTIVE: CGRP, a neuropeptide involved in migraine pathophysiology, is also known to play a role in the respiratory system and in immunological conditions such as sepsis. We analyzed the impact of the use of CGRP antagonists in patients with migraine during the COVID-19 pandemic, caused by the SARS-CoV-2 coronavirus. METHODS: This is a multicentre cross-sectional study. From May to November 2020, through a national survey distributed by the Spanish Society of Neurology, we collected data about the presence of COVID-19 symptoms including headache and their characteristics and severity in patients with migraine treated with anti-CGRP monoclonal antibodies (mAb), and compared them with patients with migraine not receiving this treatment. We also conducted a subanalysis of patients with COVID-19 symptoms. RESULTS: We recruited 300 patients with migraine: 51.7% (155/300) were taking anti-CGRP mAbs; 87.3% were women (262/300). Mean age (standard deviation) was 47.1 years (11.6). Forty-one patients (13.7%) met diagnostic criteria for COVID-19, with no statistically significant difference between patients with and without anti-CGRP mAb treatment (16.1% vs 11.0%, respectively; P=.320). Of the patients with COVID-19, 48.8% (20/41) visited the emergency department and 12.2% (5/41) were hospitalised. Likewise, no clinical differences were found between the groups of patients with and without anti-CGRP mAb treatment. CONCLUSION: Anti-CGRP mAbs may be safe in clinical practice, presenting no association with increased risk of COVID-19.

Antecedentes y objetivo: El péptido relacionado con el gen de la calcitonina (CGRP, por sus siglas en inglés), es un neuropéptido involucrado en la fisiopatología de la migraña, que también es conocido por participar en la regulación del sistema respiratorio y en algunas enfermedades inmunológicas como la sepsis. Hemos analizado el impacto del uso de los antagonistas de CGRP en pacientes con migraña durante la pandemia de COVID-19, causada por el coronavirus SARS-CoV-2.MétodosEstudio transversal multicéntrico desarrollado entre mayo y noviembre de 2020, en el que la Sociedad Española de Neurología distribuyó a nivel nacional una encuesta de la que recogimos datos sobre la presencia, las características y la gravedad de síntomas de COVID-19, entre los que se encontraba la cefalea, en pacientes con migraña tratados con anticuerpos monoclonales (AcM) anti-CGRP, y los comparamos con los de pacientes con migraña que no recibían dicho tratamiento. También realizamos un subanálisis de los pacientes con síntomas de COVID-19.ResultadosIdentificamos 300 pacientes con migraña: 51,7% (155/300) recibían AcM anti-CGRP; el 87,3% eran mujeres (262/300) y la edad media (desviación estándar) de la muestra fue de 47,1 (11,6) años. Un total de 41 pacientes (13,7%) cumplían los criterios diagnósticos de COVID-19, sin diferencias estadísticamente significativas entre los pacientes que recibían tratamiento con AcM anti-CGRP y los que no (16,1% y 11,0%, respectivamente; p = 0,320). De los pacientes con COVID-19, el 48,8% (20/41) acudieron a urgencias y el 12,2% (5/41) fueron hospitalizados. Igualmente, no se detectaron diferencias clínicas entre los pacientes que recibían dicho tratamiento y los que no.ConclusiónEl tratamiento con AcM anti-CGRP parece un recurso seguro en la práctica clínica, y no se asocia a un mayor riesgo de COVID-19.
