The effect of ivermectin on non-severe and severe COVID-19 disease and gender-based difference of its effectiveness
et al., Monaldi Archives for Chest Disease, doi:10.4081/monaldi.2022.2062
Retrospective 188 hospitalized patients in Pakistan, 90 treated with ivermectin, showing no significant differences with treatment. The ivermectin group had more severe disease (66% vs 58%, with 6x higher risk for severe disease patients), and more male patients (70% vs. 65%). Higher use of remdesivir and steroids in the ivermectin group also suggests that ivermectin was more likely to be given to patients in more severe condition. There were no side effects seen with ivermectin. Authors note that significantly improved ferritin levels were seen with treatment. Authors state that ivermectin patients received 2 12mg doses, 24 hours apart, but later state that the dosage was not standardized.
