Institut de Recherche Cliniques de Montreal (IRCM) Post-COVID-19 (IPCO) Research Clinic

While many COVID19 studies are focusing on the immediate biological impact of SARS-CoV2 infection, this multidisciplinary research clinic will inform the global community on its recovery phase across patient cohorts with different degrees of disease severity (asymptomatic, mild \[non-hospitalized\], moderate/severe \[hospitalized\]). The primary objectives are to: 1) evaluate the short- and long-term end-organ complications post-COVID-19 in relation to the severity of the acute COVID-19 infection and 2) establish a post-COVID-19 biobank. The secondary objective is to develop a model that can predict end-organ complications using epidemiological and clinical data. To complete the objectives, the study will follow 6 patient cohorts: Patients who had previous asymptomatic or mild COVID-19 (no need for oxygen), patients who had previous moderate/severe COVID-19 (patients who had an oxygen requirement; moderate=oxygen by nasal cannula; severe=oxygen by high flow nasal cannula, non-invasive positive pressure ventilation or intubation), patients who had COVID-19 but did not develop the post-COVID-19 condition, patients who have never had COVID-19, patients who had flu-like symptoms but did not have signs or symptoms related to the infection lasting beyond 4 weeks from the date of symptom-onset, and patients with flu-like symptoms and have signs or symptoms related to the infection lasting beyond 4 weeks from the date of symptom-onset. Patients will be recruited into these cohorts using a strategy that targets the following populations: patients that were hospitalized in centers across Montreal, patients already followed at the IRCM (non-COVID-19) clinic, essential workers, and members of the same household as patients already enrolled in the IPCO clinic research protocol. The IPCO clinic research protocol is the first in the province of Quebec to systematically follow patients post-COVID-19 for short- and long-term complications including end-organ damage while building an extensive biobank that can support future mechanistic research projects.
