#covid19: less albumin, more thrombotic risk

A new study by Sapienza University and Policlinico Umberto I Hospital of Rome, offers, for the first time, an interpretation of the thrombotic risk in Covid-19 patients, allowing early identification of individuals at high risk and opening the door to new therapeutic perspectives

Rashes, swollen legs, clogged catheters and sudden death. The “storm of blood clots” is a frequent and lethal complication in people severely affected by COVID-19.
A few studies have begun to explain the mechanisms underlying this correlation, but, to date, the right therapeutic strategy is still a distant goal.

In a new study coordinated by Francesco Violi of the Department of Internal Medicine and Medical Specialities and published on Circulation Research Journal, the team of researchers of Sapienza University and Policlinico Umberto I noted extremely low serum albumin level in patients affected by Covid-19; the team, after thorough investigations, confirmed a connection with thrombotic complications.

Regardless of one’s clinical condition, when the albumin is lower than a given range – i.e. <35g/L – risks of venous and arterial thrombosis increase; the researchers verified this data on Covid-19 patients.
The study, carried out on 73 patients hospitalised in the Infectious Diseases ward and ICU of Policlinico Umberto I Hospital in Rome, directed by Claudio Mastroianni and Francesco Pugliese respectively, demonstrated how Covid-19 patients, especially those severely affected or facing thrombotic complications, had albumin level lower than 35g/L.

Albumin is an essential protein in human blood. It has a strong anti-inflammatory effect achieved by antagonising oxidative stress effects in our body. When the serum albumin range decreases, cells produce high levels of oxygen radicals with resulting uncontrolled activation of the cells leading them to their death.

“Our job” – says Francesco Violi of the Department of Internal Medicine and Medical Specialities of Sapienza University and Director of Policlinico I Clinica Medica – “as well as giving an interpretation – to date not entirely clarified – about the thrombotic risk in Covid-19 patients, will open the door to early identification of high-risk individuals and to new therapeutic approaches aimed at reducing thromboses.”
