Anticancer drug may improve outcome for severe COVID-19 patients

Date Time Anticancer drug may improve outcome for severe COVID-19 patients Treating severe COVID-19 patients with the anticancer drug bevacizumab may reduce mortality and speed up recovery, according to a small clinical study in Italy and China that was led by researchers at Karolinska Institutet in Sweden between February and April 2020. On average, blood oxygen levels, body temperature and inflammatory markers significantly improved in patients treated with a single dose of bevacizumab in addition to standard care. The research is published in Nature Communications. Yihai Cao, photo: Ulf Sirborn “To reduce COVID-19 mortality, we aim to develop an effective therapeutic paradigm for treating patients with severe COVID-19,” says corresponding author Yihai Cao, professor of vascular biology at the Department of Microbiology, Tumor and Cell Biology at Karolinska Institutet. “Our findings suggest that bevacizumab plus standard care is highly beneficial for patients with severe

Accurate drug dosages with proton traps

The new technique may reduce drug side effects, and in the long term, ion pumps may help patients with symptoms of neurological diseases for which effective treatments are not available. The results have been published in Science Advances. Approximately 6% of the world s population suffer from neurological diseases such as epilepsy, Parkinson s disease, and chronic pain. However, currently available drug delivery methods - mainly tablets and injections - place the drug in locations where it is not required. This can lead to side effects that harm the patient.

New promising antibodies against SARS-CoV-2

They bind to the surface structures of bacteria or viruses and prevent their replication. One strategy in the fight against disease is therefore to produce effective antibodies in large quantities and inject them into the patients. The outgoing US President Donald Trump probably owes his rapid recovery to this method. However, the antibodies used to treat him have a complex structure, do not penetrate very deeply into the tissue and may cause unwanted complications. Moreover, producing antibodies is difficult and time-consuming. They are therefore probably not suitable for widespread use.
