Summary
Background: Hydroxychloroquine sulphate (HCQ) is being scrutinized for repositioning in the therapy and prevention of SARS-Cov-2 infection. This antimalarial drug is furthermore chronically frail to handle sufferers with autoimmune diseases.
Techniques: By analyzing the Portuguese anonymized files on deepest and public essentially based medical prescriptions we beget identified all cases chronically receiving HCQ for the administration of diseases similar to systemic lupus erythematosus, rheumatoid arthritis, and various autoimmune diseases. Additionally, we beget detected all laboratory confirmed cases of SARS-CoV-2 infection and all laboratory confirmed destructive cases in the Portuguese inhabitants (mandatorily registered in a centrally managed database). Notorious linking the two sets of files has allowed us to envision the proportion of HCQ chronic therapy (no longer decrease than 2 grams month-to-month) in laboratory confirmed cases of SARS-CoV-2 infection with laboratory confirmed destructive cases.
Results: Out of 26,815 SARS-CoV-2 sure sufferers, 77 (0.29%) had been chronically treated with HCQ, whereas 1,215 (0.36%) out of 333,489 destructive sufferers had been receiving it chronically (P=0.04). After adjustment for age, sex, and chronic therapy with corticosteroids and/or immunosuppressants, the possibilities ratio of SARS-CoV-2 infection for chronic therapy with HCQ has been 0.51 (0.37-0.70).
Conclusions: Our files suggest that chronic therapy with HCQ confer security in opposition to SARS-CoV-2 infection.
