Trauma and sepsis, epidemiology and pathophysiology
Trauma and sepsis are common causes for intensive care admission. These conditions are closely linked and carry high mortality. We are conducting translational studies ranging from epidemiology to in vitro experiments in this field.
The epidemiological studies on traumatology utilise trauma registries from the Karolinska trauma centre, as well as local and national health registries. Our group is also studying the prevalence and dynamics of biomarkers induced by severe trauma and sepsis. Studies are based on our plasma biobank from ICU patients.
The endothelin system and its role in sepsis have been closely studied by our group for over a decade. The dominant peptide, endothelin-1 (ET-1), is largely released in sepsis and correlated to outcome. The group has shown that ET-1, a highly vasoconstrictive peptide, contribute to hypoperfusion, pulmonary hypertension, oedema formation and cardiac dysfunction in experimental sepsis. ET-1 has also been attributed to have pro-inflammatory effects, a field currently investigated by our group.
