Background
To determine the predictive value of mid-regional pro-adrenomedullin (MR-proADM) compared to routine clinical and laboratory parameters in patients with COVID-19.

Methods
A total of 135 adult patients hospitalized with COVID-19 were included in a prospective single-centre study. In addition to routine parameters, the levels of MR-proADM in blood plasma were measured on the day of hospitalization. The patients were divided into 2 groups: those who survived and were discharged (n = 115, 85%) and those who did not survive (n = 20, 15%). Data are presented as median and interquartile range.

Results
The non-survivors had a statistically significantly greater age (73.4 [63.5–84.8] vs. 62.2 [50.3–71.4] years, P = 0.001), a lower level of haemoglobin oxygen saturation (91 [87–92] vs. 92 [92–93]%, P < 0.001), lower lymphocyte level (13 [7–30] vs. 21 [15–27]%, P = 0.03), higher lactate dehydrogenase (338 [273–480] vs. 280 [233–383] EU L–1, P = 0.04) and aspartate aminotransferase levels (49 [28–72] vs. 33 [23–47] EU L–1, P = 0.03), a higher National Early Warning (NEWS) score (7 [7– 8] vs. 6 [5–7] points, P < 0.001), and higher procalcitonin (0.16 [0.11–0.32] vs. 0.1 [0.07–0.18] ng mL–1, P = 0.006) and MR-proADM levels (1.288 [0.886–1.847] vs. 0.769 [0.6–0.955] nmol L–1, P < 0.001). MR-proADM had the highest predictive value for death during hospital stay (cut-off: 0.895 nmol L–1, AUC ROC 0.78 [95% CI: 0.66–0.90], sensitivity 75%, specificity 69%, OR 6.58 [95% CI: 2.22–19.51]).

Conclusions
Compared with other indicators, MR-proADM has the highest predictive value for in-hospital mortality in patients with COVID-19.
