Question clinique
Can hydroxychloroquine plus azithromycin improve outcomes for patients with COVID-19?
L’Essentiel
The virologic and clinical outcomes of treatment with hydroxychloroquine plus azithromycin were poor in a prospective study of 11 patients. Larger, well-designed, randomized controlled trials are needed to draw any conclusions. 2b

Sommaire
In a prospective study, French investigators assessed virologic and clinical outcomes of 11 consecutive hospitalized patients (7 men and 4 women with a mean age of 59 years) with COVID-19 who received hydroxychloroquine (HCQ) 600 mg per day for 10 days plus azithromycin 500 mg on day 1 and 250 mg on days 2 to 5. Eight patients had significant comorbidities. At the time of treatment initiation, 10 of the 11 patients had fever and received nasal oxygen therapy. Within 5 days, 1 patient died and 2 were transferred to the intensive care unit. In one patient, treatment with HCQ and azithromycin was discontinued after 4 days because of a prolongation of the QT interval. Repeated nasopharyngeal swabs in 10 patients (not done in the patient who died) using a qualitative PCR assay were still positive for SARS-CoV2 RNA in 8 patients at days 5 or 6 after treatment initiation. These virologic results stand in contrast with those reported by Gautret et al and cast doubts about the strong antiviral efficacy of this combination treatment.
