ABSTRACT
METHODS: In March 2021, a 19-item survey was sent to 420 patients with AATD who were being treated with AAT replacement therapy (prolastin) and who participated in the German AlphaCare patient program. RESULTS: The majority of the respondents (55.9%; 138) had been diagnosed with AATD ≥10 years prior to the survey and most (93.5%; 231) felt adequately informed about their disease through their physician, AlphaCare and Alpha1 Deutschland. The majority of respondents were concerned/very concerned about acquiring COVID-19. Only 1.2% of the respondents reported having been infected with SARS-CoV-2, less than the infection rate in the general population at that time (3.4%). Almost all of the respondents fully agreed/agreed that they had restricted their social contacts due to the pandemic. A substantial percentage of the responding patients fully agreed/agreed that they were concerned about being infected with COVID-19 during a visit at their doctor's office or clinic. Regarding AAT augmentation therapy, only 18 respondents reported discontinuing therapy during the pandemic, but most of these discontinuations were short-term - one was permanent. CONCLUSIONS: These survey results suggest that AATD patients are well-informed about the risks of COVID-19 with their condition and practised self-protection measures. This may have resulted in an COVID-19 infection rate lower than the general population. Although respondents were concerned about exposure to COVID-19 in their doctor's office or clinic, very few discontinued therapy even temporarily.
