The diagnostic sensitivity of IgG anti-αvβ6 in UC was 76.3%, and the specificities were 79.0% (vs. CD) and 96.0% (vs. IBS). The IgG anti-αvβ6 levels related to disease severity of the UC patients (p < 0.01-0.05). Our study shows that IgG anti-αvβ6 is associated with UC in Swedish IBD patients and that the levels of the autoantibodies reflect disease severity. IgG anti-αvβ6 could be an attractive complement to fCP in the diagnostic work up of IBD patients. We aimed to explore immune parameters in COVID-19 patients admitted to the intensive care unit (ICU) to identify distinctive features in patients with cardiac injury. A total of 30 COVID-19 patients &gt;18 years admitted to the ICU were studied on days D1, D3 and D7 after admission. Cardiac function was assessed using speckle-tracking echocardiography (STE). Peripheral blood immunophenotyping, cardiac (pro-BNP; troponin) and inflammatory biomarkers were simultaneously evaluated. Cardiac dysfunction (DYS) was detected by STE in 73% of patients 40% left ventricle (LV) systolic dysfunction, 60% LV diastolic dysfunction, 37% right ventricle systolic dysfunction. High-sensitivity cardiac troponin (hs-cTn) was detectable in 43.3% of the patients with a median value of 13.00 ng/L. There were no significant differences between DYS and nDYS patients regarding mortality, organ dysfunction, cardiac (including hs-cTn) or inflammatory biomarkers. Patients with DYS showed persistently lower lymphocyte counts (median 896 [661-1837] cells/µL vs. 2141 [924-3306] cells/µL, = 0.058), activated CD3 (median 85 [66-170] cells/µL vs. 186 [142-259] cells/µL, = 0.047) and CD4 T cells (median 33 [28-40] cells/µL vs. 63 [48-79] cells/µL, = 0.005), and higher effector memory T cells (TEM) at baseline (CD4% 10.9 [6.4-19.2] vs. 5.9 [4.2-12.8], = 0.025; CD8% 15
