Retrospective 1,534 patients (67% hospitalized) accessing long-COVID centers in Italy showing higher persistent long-COVID symptoms with antiviral treatment (97% remdesivir) after adjustment for confounders, without statistical significance. The mean interval between acute SARS-CoV-2 infection and symptom evaluation was of 338 days.
Gérard, Zhou, Wu, Kamo, Choi, Kim show increased risk of acute kidney injury, Leo, Briciu, Muntean, Petrov show increased risk of liver injury, and Negru, Cheng, Mohammed show increased risk of cardiac disorders with remdesivir.
