[Efficacy and safety of patients immunization with chronic obstructive pulmonary disease with monoclonal antibodies]

Chronic obstructive pulmonary disease (COPD) is characterized by a high level of morbidity and mortality and is associated with significant social and economic damage to the health system and society. COPD and COVID-19 have many potentially negative relationships that can lead to worse outcomes of COVID-19, including impaired lung function, old age and the presence of concomitant diseases Aim. To assess efficacy and safety of the drug Tixagevimab + Cilgavimab for the pre-contact prevention of COVID-19 infection in patients with COPD.

A total of 324 male patients were included in the study, who were treated or monitored at the Regional Clinic Hospital №3 and the Regional Pulmonological Center of Chelyabinsk in April-May 2022. The main endpoints of observation, for 3 and 6 months, to assess the effectiveness were the dynamics of shortness of breath according to The Modified Medical Research Council Dyspnea Scale - mMRC, the The forced expiratory volume in 1 second, the number of exacerbations, emergency calls, hospitalizations, polymerase chain reaction for SARS-CoV-2. Local and general reactions after immunization were evaluated. The drug Evusheld (150 mg Tixsagevimab +150 mg Cilgavimab, AstraZeneca) was used for immunization.

The effectiveness of pre-contact prevention of COVID-19 was 88.8%. The administration of the drug does not provoke an exacerbation of the underlying disease. The main clinical and functional indicators have positive dynamics by the 6th month of follow-up. The drug is well tolerated and has no significant both early and late complications.
