Key Takeaways

In this study, the clinical outcomes and adverse drug events were explored in patients hospitalized with COVID‐19 treated with off‐label hydroxychloroquine (HCQ) and azithromycin (Az). Researchers conducted a retrospective analysis of hospitalized patients who had a positive polymerase chain reaction test for SARS‐CoV‐2 and received HCQ plus Az or no targeted therapy. The primary outcome included clinical improvement on day 7 defined as either hospital discharge or improvement of 2 points on a 6‐category ordinal scale. The mortality at day 28, intensive care admission, the requirement for mechanical ventilation and incidence of adverse events were considered as secondary outcomes. They examined data from a total of 134 patients; 82 patients received HCQ/Az and 52 patients received no targeted therapy.  It was shown that the administration of these repurposed drugs did not result in clinical improvement and was associated with a significant increase in toxicity, although patients who received HCQ/Az were more severely ill. This descriptive study indicates the utility of monitoring all repurposed agents for adverse events.
