Network medicine aims at using networks to uncover patterns in diseases and use them to understand their biology and propose new drugs.
Since the appearance of Covid19, the disease provoked by the SARS-Cov-2 virus, the research community all around the globe has been on a race to develop treatments or repurpose existing drugs for this new challenge.
We are now relieved by the existence of effective vaccines, but better understanding of this disease will improve treatment of patients who keep succumbing to it while the logistic challenge of world-wide vaccination is met.
We therefore suggest the use of network medicine to reveal the biological processes affected by this disease by compiling information from multiple public databases collecting information on protein and drug interactions as well as symptoms for other diseases .
In this study we introduce CovMulNet19, a comprehensive COVID-19 network containing all available known interactions involving the SARS-CoV-2 virus proteins, interacting-human proteins, related diseases, symptoms and drugs that can potentially target them. We used extensive network analysis methods to prioritize a list of diseases that display a high similarity to COVID-19 and a list of drugs that could potentially be beneficial to treat patients. Amongst the diseases that have high similarity with COVID-19, we find some of the conditions that were reported to be risk factors in patients to develop severe forms of COVID-19, including intestinal, hepatic, and neurological diseases as well as other respiratory conditions.
The database CovMulNet19 can be used as a valuable tool for exploring drug repurposing options but also to better understand the symptomatology of COVID-19, especially in the long-term forms. The network approach accounts for the intertwined relationships between molecular interactions, diseases and symptoms of this and all other diseases.
