Hydroxychloroquine

Background of the Study:

The controversial study by French researcher Didier Raoult, published on March 20, 2020, claimed that hydroxychloroquine (HCQ) and HCQ combined with azithromycin significantly reduced SARS-CoV-2 viral load.
The paper was retracted on December 17, 2024, due to concerns about ethical approval and methodological issues.

About Hydroxychloroquine (HCQ)

Hydroxychloroquine is a medication primarily used to treat malaria, rheumatoid arthritis, and systemic lupus erythematosus (SLE).
It reduces immune system activity or kills the malaria-causing parasites from Anopheles mosquito bites.

Use in Autoimmune Disorders:

Effective in managing rheumatoid arthritis by reducing joint inflammation.
Helps treat lupus by controlling the overactive immune response.

HCQ and COVID-19:

Early studies claimed HCQ could reduce SARS-CoV-2 viral loads, especially in combination with azithromycin.
Proposed as a prophylactic to prevent COVID-19 infection; however, large-scale use raised concerns due to:
- Cardiac arrhythmia risks
- Liver damage
- Potential weakening of the immune system’s response to infection.
