An interesting Lancet case series on pregnant mothers with confirmed COVID19 – all 9 moms survived, and delivered healthy babies with no evidence of detectable coronavirus in cord blood, throat, or amniotic fluid in any of the nine babies suggesting a low risk of transplacental transmission.

There is a fast track phase 3 trial of 1,000 patients here and in China. This is a therapeutic “game changer” based on its success when used in compassionate use outcomes in a limited number of people. It has a therapeutic window when used in the first 5-10 days before the cytokine storm sets in. Currently IL-6 inhibitor are being studied to attenuate the inflammatory response i.e. “cytokine storm” caused by the immune response in the lung to COVID19
