Basel Study: Why Lopinavir and Hydroxychloroquine Do Not Work on Covid-19
Lopinavir is a drug against HIV, hydroxychloroquine is used to treat malaria and rheumatism. Until recently, both drugs were regarded as potential agents in the fight against the coronavirus SARS-CoV-2. A research group from the University of Basel and the University Hospital Basel has now discovered that the concentration of the two drugs in the lungs of Covid-19 patients is not sufficient to fight the virus.
In February 2020, a Covid-19 patient cohort was established at the University and the University Hospital in Basel to prospectively monitor a range of diagnostic means and potential treatments for Covid-19, including the off-label use of hydroxychloroquine and lopinavir/ritonavir.
A research group monitored lopinavir plasma levels in Covid-19 patients. “Considering that substantial inflammation was observed in these patients, and previous studies have shown the inhibition of drug metabolism by systemic inflammation, we had the rationale to investigate the effect of inflammation on lopinavir and hydroxychloroquine plasma levels,” states Professor Catia Marzolini, first author of the study and professor for experimental medicine at the University of Basel.

NASA Infrared Data Shows Cristina Strengthening
NASA’s Aqua satellite revealed better organization and colder cloud top temperatures in Tropical Storm Cristina, indications that the storm was strengthening.
On July 10 at 4:35 a.m. EDT (0835 UTC), the MODIS instrument aboard NASA’s Aqua satellite analyzed Tropical Storm Cristina’s cloud tops in infrared light. Infrared data provides temperature information, and the strongest thunderstorms that reach high into the atmosphere have the coldest cloud top temperatures.
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA’s Aqua satellite found that the most powerful thunderstorms were east and south of the center of circulation, where temperatures were as cold as or colder than minus 70 degrees Fahrenheit (minus 56.6 Celsius). These cloud top temperatures had become colder than they were over the previous day. Cloud top temperatures that cold indicate strong storms with the potential to generate heavy rainfall.
