The evidence available to assess the level of risk and the outcome of infection with COVID-19 in AATD patients is extremely limited. Most patients with AATD have adhered to strict self-isolation and shielding practices, which has limited their exposure to COVID-19 and, as a direct consequence, the incidence of infection in this group of patients appears to have remained low. Sporadic reports of infection with COVID-19 in AATD patients would suggest that the early outcomes are not as poor as the AATD expert community would have predicted.
The IMCA1 study aims to collate information on clinician experience of COVID-19 infection in patients with AATD across the EU countries using a pre-existing consortium of AATD researchers (EARCO) that is supported by the European Respiratory Society.
