Brief Summary:
Based on data regarding the effect of colchicine on the inflammasome NLP3 and microtubule formation and associations thereof with the pathogenetic cycle of SARS-COV-2, the question arises whether colchicine, administered in a relatively low dose, could potentially have an effect the patients' clinical course by limiting the myocardial necrosis and pneumonia development in the context of COVID-19. If present, this effect would be attributed to its potential to inhibit inflammasome and (less probably) to the process of SARS-CoV-2 endocytosis in myocardial and endothelial respiratory cells.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

Patients >18 years old with laboratory confirmed SARS-CoV-2 infection (RT PCR) AND body temperature >37.5 degrees centigrade AND at least two of: i. sustained coughing, ii. sustained throat pain, iii. anosmia and/or ageusia, iv. fatigue/tiredness, v. PaO2<95 mmHg.

Exclusion Criteria:
