A study from the Vall d’Hebron Campus demonstrates that the Ex Vivo C5b-9 deposition test is useful for monitoring the activity of the complement system (CS) in patients with aHUS or transplant-associated TMA.

The results show that, in some patients with mutations in the X chromosome, the healthy gene is inactivated and the mutated gene manifests itself, which favors the onset of the disease.

Researchers have used an innovative protocol to identify people with this autoimmune disease who have a higher risk of cancer.

As age increases in men, the concentration of the hormone in the blood drops and this increases the likelihood of severe progression of the infection in COVID-19 patients

The work used a machine learning system to show that certain immunological patterns are related to a more severe progression of the disease and more mortality.

The publication summarises the main results showing that at least 20% of cases of severe pneumonia after SARS-CoV-2 infection are explained by genetic and immunological anomalies.

This year, the Vall d'Hebron team has participated in the publication of three articles to understand the 2016 enterovirus A71 (EV-A71) outbreak in Catalonia and the follow-up of non-polio enteroviruses today.

Researchers have found lung-resident memory T lymphocytes months after SARS-CoV-2 infection, which would rapidly activate in the event of possible reinfection.
