Comparison of hydroxychloroquine, lopinavir/ritonavir, and standard of care in critically ill patients with SARS-CoV-2 pneumonia: an opportunistic retrospective analysis

https://doi.org/10.1186/s13054-020-03117-9

In this retrospective observational study, eighty patients were treated during a 4-week period and included in the analysis: 22 (28%) received standard of care only, 20 (25%) patients received lopinavir/ritonavir associated to standard of care, and 38 (47%) patients received hydroxychloroquine and standard of care. Baseline characteristics were well balanced between the 3 groups. Treatment escalation occurred in 9 (41%), 10 (50%), and 15 (39%) patients who received standard of care only, standard of care and lopinavir/ritonavir, and standard of care and hydroxychloroquine, respectively (p = 0.567). There was no significant difference between groups regarding the number of ventilator-free days at day 28 and mortality at day 14 and day 28. Finally, there was no significant change between groups in viral respiratory or plasma load between admission and day 7. In critically ill patients admitted for SARS-CoV-2-related pneumonia, no difference was found between hydroxychloroquine or lopinavir/ritonavir as compared to standard of care only on the proportion of patients who needed treatment escalation at day 28.
