Hydroxychloroquine with azithromycin in patients hospitalized for mild and moderate COVID-19

The active group comprised 101 (52.3%) patients using hydroxychloroquine associated with azithromycin and the control group 92 (47.7%) patients who did not take these medications. Median age was 59 (47-70) in the active group and 65 (47-77) in the control group (p<0.05). Patients in the control group had greater extent of pulmonary involvement on baseline chest CT scans (p<0.05). In the medication group, 25% (25 out of 101) were admitted to the ICU, compared to 21% (19 out of 92) in the control group (p>0.05). No difference in mortality, duration of non-invasive oxygen use or duration of hospitalization was seen between groups. The therapeutic regimen was well tolerated, with only eight (7.9%) patients presenting gastrointestinal symptoms and eight (7.9%) patients withdrawn treatment due to QTc prolongation. Patients treated with hydroxychloroquine combined with azithromycin and the control group had similar clinical outcomes. This therapeutic regimen was considered ineffective in hospitalized patients with mild to moderate COVID-19 related ARDS and was associated with few non-severe adverse events.
